Description

A kind of hand snap ring Press Plier

Technical field

The utility model relates to a kind of pipelayer's tool, is specifically related to a kind of hand snap ring Press Plier.

Technical background

The pipeline that is used for various installations as the product sale; all be to sell according to the yardstick that manufacturer's product specification is determined; especially various little pipe fittings; it is in work progress; usually can be as the case may be; carry out cutting to adapt to construction requirement, therefore, the Press Plier that is used for the pipe fitting cutting just highlights its importance.

Existing a kind of hand Press Plier, as shown in Figure 1, it is made up of caliper 12, pincers snap ring 11, lock-screw 13 3 parts, and lock-screw 13 radially passes pincers snap ring 11, is fixed on the Clamp 12; Because the pincers snap ring needs frequent dismounting and change, and during its dismounting and change, need to screw out lock-screw, because lock-screw is relatively independent parts, the volume of part own is less, is not easy to be found, so in unloading process, lose easily, in addition, the replacing of this mode, extremely inconvenient in use.

In sum, develop the simple hand Press Plier of a kind of use, become the focus of paying close attention in the industry.

Summary of the invention

At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of hand snap ring Press Plier, and it has effectively avoided the phenomenon that part is lost takes place in the renewal part process, and makes things convenient for the part dismounting and change.

For achieving the above object, the utility model adopts following technical scheme:

A kind of hand snap ring Press Plier, comprise caliper with an installing hole, be positioned at the pincers snap ring of described caliper installing hole, described pincers snap ring is provided with a connection piece, described caliper is provided with one can be along the axially movable slide assemblies of described installing hole, and the free end of described slide assemblies is provided with and can clamps the fastener that is connected with described connector.

Described connector is for being axially set in the groove of described pincers snap ring edge along described installing hole, described fastener is the projection that can be connected with described groove coupling.

Described slide assemblies comprises that being parallel to described installing hole is axially set in first through hole on the described caliper, is plugged in described first through hole and can pushes screw in axial sliding along first through hole; Described projection is fixedly installed in the described free end of pushing screw.

Described slide assemblies also comprises and is socketed on the described flexible member of pushing the screw outside, and described flexible member is at described caliper and push between the press-side of screw.

This hand snap ring Press Plier also is provided with a limit assembly, it comprises and is arranged at second parallel with described first through hole on the described caliper through hole, being plugged in described second through hole can be along second through hole guide finger in axial sliding, and described guide finger is fixedlyed connected with described projection.

The hand snap ring Press Plier that the utility model is set forth, its beneficial effect is:

1, avoided losing of accessory, the convenient use;

2, can realize the quick loading and unloading of snap ring are changed;

3, it is simple in structure, is convenient to constructing operation, helps promoting the use of.

The specific embodiment

Below, in conjunction with the accompanying drawings and the specific embodiment, hand snap ring Press Plier of the present utility model is described further, so that clearerly understand the utility model technological thought required for protection.

As Fig. 2,3,4,5, shown in 6, be a kind of hand snap ring Press Plier of the present utility model, comprise caliper 22, and snap ring 21, snap ring 21 is installed in the default installing hole 23 of caliper 22, caliper 22 is provided with the thickness direction along caliper 22 parallel to each other (just installing hole 23 is axial) two manholes 225,226, push screw 224 in through hole 225 cross-under, push the aperture coupling of the exterior contour and the through hole 225 of screw 224, can along through hole 225 axially, slide with respect to caliper 22, the free end (just relative with its a press section end) of pushing screw 224 is fixedly connected with a projection 221, when the press-side of pushing screw 224 was exerted pressure, it drove projection 221 endwisely slipping along installing hole 23; In order to make the projection 221 after sliding to get back to initial position easily, be connected to a spring 223 pushing screw 224 outer cover, spring 223 is between the press-side of pushing screw 224 and caliper 22, when exerting pressure when impelling projection 221 to slide into caliper 22 disengaged positions to pushing screw 224 press-sides, spring 223 is extruded, after discharging to the pressure of pushing screw 224, the screen resilience of spring 223 becomes pushing the buffer brake of screw 224, this moment projection 221 driven to lock body 22 tight close position, just initial positions.

As shown in Figure 5, on above-mentioned snap ring 21, be provided with the groove 211 that is provided with along its thickness direction (installing hole 23 is axial), the profile of groove 211 and projection 221 shaped upper parts coupling.

When above-mentioned projection 221 was fitted in caliper 22 surfaces, the top of projection 221 was connected to the inside of groove 211, and when projection 221 broke away from caliper 22, then its top and groove 211 broke away from.

Fig. 4,5 for another example, and in conjunction with shown in Fig. 6,7, the inventor is in order to play guiding and position-limiting action to the activity of projection 221, cross-under has a guide finger 222 in through hole 226, it can be axially movable along through hole 226, that is to say that its direction of motion is consistent with the direction of motion of pushing screw 224, fixedlys connected with projection 221 tops in the end of guide finger 222.Because guide finger 222 all is to be fixed on the projection 221 with pushing screw 224, define projection 221 along the trend of pushing screw 224 axial rotation; Certainly, according to general mechanical general knowledge, can adopt above-mentioned guide finger structure, also can realize limiting projection along the purpose of pushing screw axial rotation trend, concrete is, above-mentionedly is used for cross-under and pushes the through hole of screw and be set to square opening, then corresponding push screw to be provided with the cross section be the square pin of pushing, other structures are same as described above, do not do too much description here.

The inventor states in the process of technical scheme in realization, has also adopted other modes, for example, changes the shape at above-mentioned groove and projection top or the like; In addition, in use, prevent the disengaging of snap ring and caliper, the end that above-mentioned guide finger is connected with projection also has an anticreep bolt.

Certainly, above-mentioned hand snap ring Press Plier can be installed the device of a plurality of above-mentioned mutual fastenings simultaneously in the utility model on lock body, thereby realizes the multiple spot of snap ring is locked along the periphery of snap ring, can effectively guarantee normal use of the present utility model.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to technical scheme described above and design.
