Abstract
The utility model discloses a bolt installation and detachment device. The bolt installation and detachment device is characterized by comprising a cylinder body (1), an annular magnet (2) and an annular gasket (3); the empty chamber (10) is formed inside the cylinder body (1); one end of the cylinder body (1) is opened and the other end of the cylinder (1) is closed and fixedly connected with a handle (11); the annular magnet (2) is fixed in the empty chamber; the annular gasket (3) is fixed on the annular magnet (2); the inner diameter of the annular gasket (3) is equal to that of the annular magnet; the outer diameter of the annular gasket (3) is equal to that of the annular magnet. According to the bolt installation and detachment device, bolts and nuts which are utilized can be attracted, the impact to the strong magnet can be reduced, and accordingly the damage to the strong magnet is avoided and the service life of the tool is extended.
Description
Technical field
The utility model relates to bolt and nut technical field, relates in particular to a kind of instrument that is used for mounting and dismounting bolt and nut.
Background technology
In thread connection, there is an annular strong magnet 2(fastening means inside of often using as shown in Figure 1), its Main Function is to hold bolt and nut, improves employee's operating efficiency.But the service life comparatively of short duration (life cycle is half a day to 1 day) of strong magnetic, if the instrument that strong magnetic fragmentation often just need to more renew, thus production cost increased.
Summary of the invention
The purpose of this utility model is exactly the problem existing in order to overcome above-mentioned prior art, a kind of bolt loading and unloading device is provided, can either holds used bolt and nut, can reduce the impulsive force that strong magnetic is subject to again, thereby avoided strong magnetic damaged, reached the object that extends tool life.
For realizing above-mentioned purpose of the present utility model, provide following technical scheme:
A bolt loading and unloading device, comprising: cylindrical shell, and its inside has cavity, one end opening, the other end seals and is fixedly connected with handle; Annular magnet, is fixed in described cavity; Annular gasket, is fixed on described annular magnet, and its internal diameter equates with described annular magnet internal diameter, and its external diameter equates with the external diameter of described annular magnet.
Preferably, it is that circular circle segments and cross section is polygonal polygon section that described cavity comprises cross section, and the junction of circle segments and polygon section forms step; Wherein, described circle segments is near one end of described handle, and described polygon section is near one end of described opening.
Preferably, described annular magnet is fixed on described step, the internal diameter of described annular magnet and the equal diameters of described circle segments.
The beneficial effects of the utility model embody in the following areas:
The utility model increases one deck pad on annular magnet, can either hold bolt to be loaded and unloaded or nut, can reduce the impulsive force that annular magnet is subject to again, thereby has avoided strong magnetic damaged, has reached the object that extends tool life.

Fig. 1 is the structure chart of prior art bolt loading and unloading tool;
Fig. 2 is the structure chart of the utility model bolt loading and unloading tool;
Description of reference numerals: 1-cylindrical shell; 10-cavity; 10a-circle segments; 10b-polygon section; 11-handle; 2-annular magnet; 3-annular gasket
The specific embodiment
Fig. 2 is the structure chart of the utility model bolt loading and unloading tool; As shown in Figure 2, bolt loading and unloading device of the present utility model comprises: cylindrical shell 1, and its inside has cavity 10, an end opening of cylindrical shell 1, the other end seals and is fixedly connected with handle 11; Annular magnet 2, is fixed in cavity 10, to bolt to be loaded and unloaded or nut are inhaled in cavity 10; Annular gasket 3, is fixed on annular magnet 2, and its internal diameter equates with annular magnet internal diameter, and its external diameter equates with the external diameter of annular magnet.
Wherein, as shown in Figure 2, it is that circular circle segments 10a and cross section is polygonal polygon section 10b that cavity 10 of the present utility model comprises cross section, for example the cross sectional shape of polygon section 10b can be applicable to hex bolts or hex nut for hexagon makes handling instrument of the present utility model, and the junction of circle segments 10a and polygon section 10b forms step; Wherein, circle segments 10a is near one end of handle 11, and polygon section 10b is near one end of opening.Annular magnet 2 is fixed on step, the internal diameter of annular magnet 2 and the equal diameters of circle segments, thus make, when using handler of the present utility model that nut is fixed on bolt, to avoid occurring the phenomenon of existing bolt card on annular magnet.When needs load and unload bolt or nut, the openend of cylindrical shell 1 is aimed to bolt to be loaded and unloaded or nut, and the hexagonal cross-section of openend is alignd with the hexagonal cross-section of bolt or nut, bolt or nut are entered in polygon section 10b and under the effect of magnet to be inhaled on pad, at this moment turn handle 11, just can turn bolt to be loaded and unloaded or nut.
Although above-mentioned, the utility model is described in detail; but the utility model is not limited to this; those skilled in the art can modify according to principle of the present utility model; therefore, all various modifications of carrying out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
