Preferably, the back of the chest card is provided with a clothes clamping groove, and the pintle of the pintle mechanism passes through the clothes clamping groove to fasten clothes.
Preferably, the pin mechanism further comprises a spring for resetting.
Preferably, the sliding block is arranged in the sliding rail, the locking piece is rotationally connected inside the chest card, and the locking piece is provided with a protruding block which is matched with the extending block on the sliding block to form a driving chain.
Preferably, the unlocking piece is a key, and a key hole matched with the key is formed in the locking piece.
Preferably, the pressing block is provided with a groove for being matched with the sliding block to be clamped when the pressing block is pressed down.
Preferably, the movable lock mechanism comprises a first sliding block used for clamping the pressing block, a movable lock used for driving the first sliding block to move along the first sliding rail and a first elastic piece used for resetting the first sliding block.
Preferably, the movable lock mechanism and the locking mechanism are respectively arranged on different two sides of the pintle mechanism.
Preferably, the pressing block is provided with a first groove for being matched with the first sliding block to be clamped when the pressing block is pressed down.
Compared with the prior art, the invention has the following beneficial effects: after the chest card is fastened with clothes through the pintle of the pintle mechanism, the sliding block locked by the locking mechanism is used for locking the pressing block of the pintle mechanism, so that the chest card is locked, illegal disassembly is prevented, and normal monitoring of the chest card is ensured.

Detailed Description
Embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Example 1
As shown in fig. 1 to 4, an anti-disassembly chest card comprises a chest card 1 and a needle mechanism 2 and a locking mechanism 3 which are arranged on the chest card, wherein the needle mechanism 2 comprises a pressing block 21 and a needle 22 connected with the pressing block, the locking mechanism 3 comprises a sliding block 31 for clamping the pressing block, a locking piece 32 for driving the sliding block to move and an elastic piece 33 for resetting the sliding block, and the locking piece 32 is provided with an unlocking piece 322. The chest card is locked by the locking piece driving sliding block locking pressing block, and can be unlocked only by the matched unlocking piece, so that the purposes of locking and preventing disassembly are achieved, and the data monitoring function of the chest card is effectively guaranteed.
The back of the chest card is provided with a clothes clamping groove 11, the pressing block 21 is pressed down, and the buckling needle 22 passes through the clothes clamping groove to buckle clothes. The needle buckling mechanism can be further provided with a reset spring 23, one end of the spring is connected with the pressing block, the other end of the spring props against the inner wall of the chest card clothes clamping groove, elastic potential energy is stored when the pressing block is pressed down, and after unlocking, the needle buckling mechanism can automatically reset by means of elasticity of the spring.
The sliding block 31 of the locking mechanism 3 is arranged in the sliding rail 331, and the sliding rail 331 is a through groove of the fixed block 31 fixed inside the chest card. One end of the sliding block 31 is connected with the elastic piece 34, and the other end is used for matching with the groove 211 on the pressing block to lock the pressing block 21. The lock 32 is rotatably connected inside the chest card, a key hole for external unlocking is formed in the lock, an unlocking piece 322 matched with the lock is a key, and an opening of the key hole is correspondingly formed in the front face of the chest card. The lock 32 is provided with a bump 321 forming a driving chain with the extension block 311 of the slider, and when the lock is turned by an external key, the bump on the lock drives the extension block to drive the slider to move linearly along the sliding rail. When in locking, the pressing block is pressed down, and the sliding block is matched with the groove on the pressing block to lock the pressing block under the driving of the elastic force of the elastic piece; when unlocking, the lock is rotated by the key to enable the sliding block to move along the compression direction of the elastic piece, after the sliding block leaves the groove on the pressing block, the pressing block resets under the elastic force of the spring, the button needle is sprung away from clothes, and after the key is released, the sliding block automatically resets under the elastic action of the elastic piece.
Example 2
In this embodiment, the chest card is internally provided with a pin mechanism 2, a locking mechanism 3 and a movable lock mechanism 4, which are the same as those of embodiment 1, and are respectively arranged on the left and right sides of the pressing block. The chest card in the embodiment can be used in a general state, and the pressing block can be locked by the movable lock mechanism under the condition that locking and anti-disassembly are not needed; under the condition of locking and preventing disassembly, the locking mechanism is used for locking the pressing block, and the locking block can only be unlocked by a key.
As shown in fig. 5 and 6, the movable lock mechanism 4 includes a first slider 41 for catching the pressing block 21, a movable lock 42 for driving the first slider to move along the first slide rail, and a first elastic member 43 for resetting the first slider. The movable lock 42 adopts a button type structure, and the slide block is driven to move along a first slide rail 441 by pressing down the middle upright post 421, wherein the first slide rail is a through groove of a first fixed block 44 fixed in the chest card. The first slider 41 is connected with the first elastic member 43, and when the movable lock is pressed down to drive the first slider to move along the first sliding rail to clamp the first groove 212 of the pressing block, the first elastic member stores elastic potential energy, the movable lock is pressed down again, after the middle upright post is reset, the first slider is reset under the elastic potential energy of the first elastic member, and the pressing block is reset under the elasticity of the spring.
