Description

A kind of stopping means

Technical field

The utility model relates to a kind of clamping device, particularly relates to a kind of stopping means of securing member.

Background technology

At present, the product of my department, as before the bolted on header box is on casing, needs to pad upper gasket between nut and casing, to play insulation and anti-skidding effect, but, in the process tighted a bolt, this packing ring can the transfer along with the rotation of bolt, like this, bolt can be caused can not to be fastened on casing, after of long duration, bolt can unclamp, and header box can vibrate at running casing, and space becomes large, dust in air or rainwater etc. may infiltrate in case, cause the danger such as short circuit.

Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of stopping means, make it have more value in industry.

Utility model content

For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of being conducive to the stopping means of bolted on casing.

Stopping means of the present utility model, the bare terminal end comprising handle and be fixedly connected with handle one end, described bare terminal end front end is provided with groove, this groove front opening, and this groove runs through bare terminal end from top to bottom, described recess edge is circular arc, and radius corresponding to the arc section of this circular arc from slot opening to bottom portion of groove reduces gradually, and the described handle other end is provided with handle.

Concrete, this handle and handle have angle, or this foldable handle.

Further, described recess edge is distributed with sawtooth.

Further, described handle comprises first handle and second handle, described bare terminal end comprises the first bare terminal end and the second bare terminal end, described first bare terminal end is fixedly connected with second handle, described second bare terminal end is fixedly connected with first handle, described first bare terminal end is arranged in a crossed manner with the first handle section of being fixedly connected with the second bare terminal end with the second handle section of being fixedly connected with and have motion bar to run through described infall, and described motion bar two ends are provided with block.

Further, round tube hole is provided with in the middle part of described handle.

Further, also slotted hole is provided with in the middle part of described handle.

By such scheme, the utility model at least has the following advantages:

Stopping means of the present utility model, front end is provided with the groove of band circular arc, and the packing ring of various shape can block by this groove, so that bolt is fastening smoothly, handle of the present utility model can help staff to hold with a firm grip handle, and what make packing ring is fastening easier.

Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model stopping means;

Fig. 2 is the structural representation of the another kind of embodiment of the utility model.

Detailed description of the invention

Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.

See Fig. 1 and Fig. 2, stopping means described in the utility model one preferred embodiment, the bare terminal end 2 comprising handle 1 and be fixedly connected with handle 1 one end, bare terminal end 2 front end is provided with groove, this groove front opening, and this groove runs through bare terminal end 2 from top to bottom, recess edge 3 is circular arc, and radius corresponding to the arc section of this circular arc from slot opening to bottom portion of groove reduces gradually, the handle other end is provided with handle 4; The effect that the radius that the arc section of circular arc from slot opening to bottom portion of groove is corresponding reduces gradually is, larger near slot opening place bore, less near bottom portion of groove circular arc respective radius, like this, bare terminal end can adapt to the difform packing ring of different size.

Concrete, this handle and handle have angle, or this foldable handle; Like this, when only having casing around packing ring, staff is facilitated to carry out clamping washer by holds handle.

In order to improve the chucking power of bare terminal end, increasing frictional force during clamping, recess edge 3 being distributed with sawtooth (not shown); Like this, sawtooth can produce certain clip power with the edges and corners of packing ring, adds clamping dynamics, after packing ring is clamped by bare terminal end, is not easy to slide.

See Fig. 2, in order to the packing ring making bare terminal end can adapt to more large gauge, handle comprises first handle 5 and second handle 6, bare terminal end 2 comprises the first bare terminal end 7 and the second bare terminal end 8, first bare terminal end 7 is fixedly connected with second handle 6, second bare terminal end 8 is fixedly connected with first handle 5, first bare terminal end 7 is arranged in a crossed manner with first handle 5 section of being fixedly connected with the second bare terminal end 8 with second handle 6 section of being fixedly connected with and have motion bar 9 to run through described infall, and motion bar 9 two ends are provided with block (not shown); Like this, by strutting the distance between first handle and second handle, the distance between the first bare terminal end and the second bare terminal end can be made larger, the packing ring of more large gauge can be clamped.

Conveniently access of the present utility model, is provided with round tube hole 10 in the middle part of handle; Like this, by round tube hole, can be suspended on wall or cabinet wall, save space.

In order to prevent in clamping packing ring process, bare terminal end rotates together along with packing ring, is also provided with slotted hole 11 in the middle part of handle 1; Like this, can be stuck in slotted hole by other object and ensure the stable of handle and bare terminal end.

The above is only preferred embodiment of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
