A kind of sampling pipe clamp in water quality testing meterTechnical field
The present invention relates to water quality testing meter technical field, particularly a kind of sampling pipe clamp in water quality testing meter.
Background technology
With the development of society, people also constantly strengthen for the consciousness of environmental protection, during to environmental protectionNeed to apply to water quality testing meter, existing water quality testing meter needed to carry out water quality sampling before target is detected, butIt is very big to be that existing sampling pipe clamp there is a problem that, so designing a kind of for water quality inspection to improve its operating efficiencyThe sampling pipe clamp surveyed in instrument is just particularly important.
The content of the invention
The technical problem to be solved in the invention is to stretch into the length in the first sleeve by adjusting second sleeve to adapt toThe length of probe tube in protection sleeve is put into, the effect for increasing its Practical Performance is served；There is provided a kind of for water quality testing meterIn sampling pipe clamp.
To solve above-mentioned technical problem, structure of the invention includes
Protection sleeve, is placed with probe tube in described protection sleeve, described protection sleeve is by the first sleeve and theTwo sleeves are vertically connected with composition, and the upper end of described second sleeve is movably connected in the lower end of the first sleeve, and described firstThe first screwed hole is offered on the lateral wall of sleeve lower end, the first puller bolt is connected with the first described screwed hole, it is describedThe first puller bolt be connected with second sleeve through the first screwed hole, the outer sheath of described the first sleeve upper end is equipped with spacingSeat, the lower end of described second sleeve is in sealing shape,
Annular chuck, described annular chuck is movably connected in the outside of the first sleeve, and its upper end connects with limit baseTouch, groove, described annular chuck and first set are offered relative to the position of the first puller bolt on described annular chuckPositioning and clamping mechanism is additionally provided between cylinder,
Handle, described handle is telescoping handle, and described handle is connected on the side wall of annular chuck.
Further：Described positioning and clamping mechanism includes the gathering sill being opened on annular chuck madial wall, is opened in theHemispherical draw-in groove, spherical dop and spring on one sleeve lateral wall, described spherical dop are connected to gathering sill by springInterior, described spherical dop is snapped in hemispherical draw-in groove under the action of the spring.
Further：Described handle is made up of first connecting rod, second connecting rod and the second puller bolt, and describedThe left end of two connecting rods is movably connected in the right-hand member of first connecting rod, and the left end of described first connecting rod 11 is fixedly connected on marmon clampOn head, the second screwed hole is offered on the side wall of described first connecting rod right-hand member, the second described puller bolt passes through the second spiral shellPit is in contact with second connecting rod.
After said structure, the present invention stretches into the length in the first sleeve by adjusting second sleeve and adapts to be put into guarantorThe length of probe tube in pretective sleeve pipe, serves the effect for increasing its Practical Performance；And the design also has simple structure, is easy toManufacture and the advantage of practicality and high efficiency.

Specific embodiment
A kind of sampling pipe clamp in water quality testing meter as shown in Figure 1, including protection sleeve, the and of annular chuck 4Handle 6, is placed with probe tube in described protection sleeve, described protection sleeve is by the first sleeve 1 and second sleeve about 2Connection composition, the upper end of described second sleeve 2 is movably connected in the lower end of the first sleeve 1, the described lower end of the first sleeve 1Lateral wall on offer the first screwed hole, be connected with the first puller bolt 3 in the first described screwed hole, the first described topTight bolt 3 is connected through the first screwed hole with second sleeve 2, and the outer sheath of the described upper end of the first sleeve 1 is equipped with limit base 5,In sealing shape, described annular chuck 4 is movably connected in the outside of the first sleeve 1 for the lower end of described second sleeve 2, its upperEnd is in contact with limit base 5, and the position on described annular chuck 4 relative to the first puller bolt 3 offers groove, describedPositioning and clamping mechanism is additionally provided between the sleeve 1 of annular chuck 4 and first, described handle 6 is telescoping handle, described handle 6It is connected on the side wall of annular chuck 4.The present invention stretches into the length in the first sleeve by adjusting second sleeve and adapts to be put intoThe length of probe tube, serves the effect for increasing its Practical Performance in protection sleeve.
Positioning and clamping mechanism as shown in Figure 2 includes the gathering sill 8 being opened on the madial wall of annular chuck 4, is opened in theHemispherical draw-in groove 7, spherical dop 10 and spring 9 on the lateral wall of one sleeve 1, described spherical dop 10 are connected by spring 9In gathering sill 8, described spherical dop 10 is snapped in hemispherical draw-in groove 7 in the presence of spring 9.The design has structure letterSingle, easily fabricated and practicality and high efficiency advantage
Handle 6 as shown in Figure 3 is made up of first connecting rod 11, the puller bolt 13 of second connecting rod 12 and second, describedThe left end of second connecting rod 12 be movably connected in the right-hand member of first connecting rod 11, the left end of described first connecting rod 11 is fixedly connectedOn annular chuck 4, the second screwed hole, the second described puller bolt are offered on the side wall of the described right-hand member of first connecting rod 1113 are in contact through the second screwed hole with second connecting rod 12.The present invention makes people more square during gripping by this designJust, increased its Practical Performance.
