Abstract
The utility model discloses a kind of dismantling device of profile nut, comprise base, base has the step groove that can insert cylindrical profile nut, the position of the corresponding step groove of sidewall of base offers two screws diametrically, two screws are provided with handle type index pin respectively by threaded engagement, there is the stop pin stretching into step groove the end of handle type index pin, and stop pin is corresponding with the hole clipping of the cylindrical profile nut inserting step groove, can snap in the hole clipping of profile nut sidewall.The utility model can not cause any infringement to the outer surface of profile nut in operation, can ensure the aesthetic appearance of profile nut, and service life.
Description
Technical field
The utility model relates to the dismantling device for a kind of columniform profile nut of dismounting.
Background technology
Nut coordinates with bolt or screw rod the part played the role of fastening, and is the element applied in manufacturing machine and daily life widely, nut generally have standard nut and profile nut (some irregular, grotesque nuts) point.Wherein, dismounting and the assembling of standard nut are undertaken by conventional spanner, and operation is very easy, and profile nut, then cannot be undertaken dismantling and assembling by conventional spanner, as shown in Figure 1, a kind of cylindrical profile nut 10, its outer wall is cylindrical, outer wall has annular groove 110, two hole clippings 110 are diametrically provided with in annular groove 110, in prior art, dismantle and assemble this profile nut, usually the cylindrical outer wall of profile nut only " is bitten " by pliers, firmly rotate pliers, thus make it absent-mindedness or tighten, although it can realize dismounting and the assembly manipulation of this type of profile nut substantially, but exist following not enough: 1, in operation, the circular outer wall of pliers and profile nut easily skids, dismounting and efficiency of assembling low, 2, pliers can bite the surface of profile nut, and when particularly skidding, the degree of profile nut surface damage is larger, finally causes the injurious surface mark of this type of profile nut innumerable, not only affects the outward appearance of cylindrical profile nut, also can reduce its service life.
Summary of the invention
The purpose of this utility model is to provide a kind of dismantling device facilitating demolition and the above-mentioned columniform profile nut of assembling, and ensures that the surface of profile nut is injury-free.
The dismantling device of a kind of profile nut described in the utility model, comprise base, base has the step groove that can insert cylindrical profile nut, the position of the corresponding step groove of sidewall of base offers two screws diametrically, two screws are provided with handle type index pin respectively by threaded engagement, there is the stop pin stretching into step groove the end of handle type index pin, and stop pin is corresponding with the hole clipping of the cylindrical profile nut inserting step groove, can snap in the hole clipping of profile nut sidewall.
The dismantling device of cylindrical profile nut described in the utility model, in the process of dismounting or assembling profile nut, is first pulled outwardly the handle of two handles formula index pins, and rotates to and determine stop bit, shrinks exit step groove to make stop pin; Then the step groove of the base of dismantling device is placed on outside cylindrical profile nut, profile nut is made to be inserted in the step groove of base, the handle of turn handle type index pin, makes it reset and drives stop pin to stretch into step groove, offsets with the annular groove elasticity of profile nut sidewall; Then, rotating base, makes stop pin slide, when sliding into stop pin and being relative with hole clipping along the annular groove of cylindrical profile nut outer wall, under elastic force effect, stop pin can be inserted in hole clipping, by extracting tool and circular profile nut locked, now, both hands hold the handle of handle type index pin, rotate dismantling device, under the drive of stop pin, cylindrical profile nut can be followed dismantling device and be rotated, thus completes dismounting or the assembling of profile nut.It is simple, convenient, and efficiency is high, and in disassembly process, the outer surface of cylindrical profile nut does not stress completely, can not cause any infringement, can ensure the aesthetic appearance of profile nut in operating process to the outer surface of profile nut, and service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of cylindrical profile nut of the present utility model;
Fig. 2 is the schematic diagram (with dotted line schematic inner structure) of the structure of the dismantling device of profile nut of the present utility model.
Fig. 3 is the dismantling device schematic perspective view of profile nut of the present utility model.
Detailed description of the invention
As Fig. 2, shown in Fig. 3, a kind of dismantling device of profile nut, comprise columned base 1, base 1 has the step groove 11 that can insert cylindrical profile nut (not shown), the position of the corresponding step groove 11 of sidewall of base 1 offers two screws diametrically, two screws are provided with the handle type index pin 2 of prior art respectively by threaded engagement, there is the stop pin 3 stretching into step groove 11 end of handle type index pin 2, this stop pin 3 can be fixed on handle type index pin 2 by screw thread, stop pin 3 is corresponding with the hole clipping of the cylindrical profile nut inserting step groove, and stop pin 3 stretches by the radial direction of operation index pin 2 along base 1, can snap in the hole clipping of profile nut sidewall.During the cylindrical profile nut of dismounting, dismantling device is placed on outside cylindrical profile nut, after in the hole clipping that operation index pin 2 makes stop pin snap in profile nut, by rotating dismantling device, profile nut can be driven to rotate, thus realize screwing and unscrewing of profile nut easily, realize dismounting fast.
The bottom of described step groove can arrange spacing end face 11, and after cylindrical profile nut inserts step groove 11, its end face and spacing end face 11 offset, and hole clipping is corresponding with stop pin 3.By this vibrational power flow, when using dismantling device dismounting profile nut, only the end face of spacing end face and cylindrical profile nut need be offseted, stop pin can be made to be positioned at the annular groove of profile nut exterior lateral sides, without the need to additionally carrying out the contraposition of annular groove and stop pin during use, operation is more simple, convenient, and stop pin 3 can fast, accurately to the hole clipping of quasi-cylindrical profile nut.
Claims (3)
1. the dismantling device of a profile nut, it is characterized in that: comprise base, base has the step groove that can insert cylindrical profile nut, the position of the corresponding step groove of sidewall of base offers two screws diametrically, two screws are provided with handle type index pin respectively by threaded engagement, there is the stop pin stretching into step groove the end of handle type index pin, and stop pin is corresponding with the hole clipping of the cylindrical profile nut inserting step groove, can snap in the hole clipping of profile nut sidewall.
2. the dismantling device of profile nut according to claim 1, is characterized in that: the bottom of described step groove can arrange spacing end face, and after cylindrical profile nut inserts step groove, its end face and spacing end face offset, and hole clipping is corresponding with stop pin.
