Description

A kind of hydraulic tongs of convenient clamping

Technical field

Sound detecting pipe connection apparatus field is the utility model is related to, more particularly to a kind of hydraulic tongs of convenient clamping.

Background technology

Sound detecting pipe is the passage that probe enters inside pile body when pouring concrete pile carries out supersonic testing method.It is bored concrete pile The important component of ultrasonic testing system, general concrete-pile is higher, needs to connect sound detecting pipe when detecting and prolongs Extend highly consistent with concrete-pile, bury again in concrete-pile afterwards, sound detecting pipe connection at present mostly will using hydraulic tongs Two sound detecting pipes being nested together are press-connected together.

The Chinese patent of Publication No. CN205009151U discloses a kind of sound detecting pipe Quick Connect Kit, it passes through hydraulic pressure Cylinder promotes flexible plier to coordinate extruding sound detecting pipe to be attached with movable plier, but movable plier passes through plug with fixed plier Pivot pin is attached fixed and departs from, and pivot pin small volume is easily lost, is not easy to look in a short time after loss when not in use To substitute, therefore man-hour influence project progress can be delayed.

Utility model content

The purpose of this utility model is to provide a kind of hydraulic tongs of convenient clamping, it, which has, facilitates sealed hydraulic tongs and sealed The advantages of mechanism will not lose.

The above-mentioned technical purpose of the utility model technical scheme is that：A kind of liquid of convenient clamping Pressing tongs, including hydraulic cylinder, stent, binding clip, flexible plier, the stent are connected with hydraulic cylinder, and described binding clip one end is cut with scissors with stent Connect, the flexible plier is connected with bracket slide, and the flexible plier coordinates extrusion pipe, the pincers by hydraulic cylinder and binding clip The head other end is provided with locked groove, and the stent side is provided with sliding slot, and locking mechanism, the sealed machine are slidably connected in the sliding slot Structure includes lock, switch, and the switch is connected with lock, and the switch control lock is inserted into locked groove by sliding slot.

By using above-mentioned technical proposal, when needing to extrude sound detecting pipe, first binding clip edge is turned on stent hinged place, it The sound detecting pipe packaged is put at flexible plier afterwards, binding clip is fastened on sound detecting pipe afterwards, pull switch makes lock along sliding slot Stretch into locked groove, just that binding clip is sealed firmly at this time, need to only be pushed back switch when needing and taking out sound detecting pipe can release to binding clip It is sealed, easy to operate and locking mechanism is arranged on internal stent, then locking mechanism will not be lost, improve hydraulic tongs make Use efficiency.

Further, the locked groove and sliding slot section are irregular roundness arcuation, and the lock section is arc-shaped, described Switch one end is connected in lock side, and the switch other end exposes stent by sliding slot.

By using above-mentioned technical proposal, the movement for making lock is circular motion, and the movement of arc-shaped will not take too much Working space, and movement is more smooth, the comfort level that operates is higher.

Further, the stent is equipped with the spacing of the switch movement of limitation locked state close to the side of locking mechanism Block, the limited block are connected with bracket slide, and the limited block glide direction is vertical with the plane that switch movement is residing.

By using above-mentioned technical proposal, when locking mechanism by binding clip it is sealed live when, limited block is reached at sliding slot, at this time Limited block card goes out switch, prevents switch from being moved along sliding slot direction, and then lock can be sealed firmly by binding clip always, improves sealed Effect.

Further, the one end of the limited block away from switch is fixed with second back-moving spring, the second back-moving spring It is connected with stent.

By using above-mentioned technical proposal, limited block is set to block switch always using second back-moving spring elastic force, while Pull open and second back-moving spring can also be used after limited block limited block is automatically reset, further improve convenience.

Further, skewback is fixed between the limited block and second back-moving spring, skewback inclined-plane upper end is slided Guide pad is connected with, the guide pad upper end is fixed with briquetting, and the briquetting only slides with the vertical direction of bracket end face.

By using above-mentioned technical proposal, pressing briquetting makes guide pad be moved to skewback direction, utilizes skewback and guide pad Inclined-plane coordinate and make skewback that limited block is pulled out sliding slot, switch restorable at this time and release locking to binding clip；By with stent The vertical direction of end face sets briquetting to make operation more smoothly, improves usage comfort.

Further, the briquetting side is fixed with pressing plate, and (the first back-moving spring is fixed between the pressing plate and stent.

By using above-mentioned technical proposal, briquetting is resetted using the elastic force of (the first back-moving spring, prevent skewback with being oriented to The inclined-plane of block coordinates second back-moving spring when producing self-locking limited block and briquetting pushed home cannot be improved the feasible of mechanism Property.

Further, shell is cased with outside the pressing plate, the shell is connected with stent, and the limited block exposes outer with briquetting Outside shell, the limited block, briquetting are slidably connected with shell.

By using above-mentioned technical proposal, shell covers (the first back-moving spring etc., plays dust-proof effect, at the same time Also limiting limited block and briquetting can only move in one direction.

Further, the hydraulic cylinder bottom is fixed with handle, and the hydraulic cylinder side is hinged with control hydraulic cylinder extension Swing handle.

By using above-mentioned technical proposal, will can need to only make at swing handle steering tiller when needing and extruding sound detecting pipe Hydraulic cylinder releases flexible plier, easy to operate.

In conclusion the utility model has the advantages that：

1st, by setting locking mechanism to make stent to the sealed more convenient of binding clip and improving the service efficiency of hydraulic tongs；

2nd, by setting the movement of limited block limit switch, locking mechanism is made to the sealed more firm of binding clip；

3rd, by setting the convenient control to limited block of the mechanisms such as briquetting, make operation more convenient, improve hydraulic tongs Usage comfort.
