Detailed Description
The present invention will be described with reference to the accompanying drawings and embodiments.
As shown in fig. 1 to 3, the present application provides a special-shaped bolt device for a high voltage switch cabinet, which refers to a combination of a special-shaped bolt for connecting various structural members of the high voltage switch cabinet and a special-shaped wrench adapted to the special-shaped bolt, wherein the special-shaped wrench comprises a handle 3 and a special-shaped joint 5. The special-shaped bolt comprises a screw rod 1 and a nut 2. The application dysmorphism bolt device is different from bolt combination such as conventional style of calligraphy, cross, interior hexagon and outer hexagon, 2 middle parts of dysmorphism bolt device nut are equipped with the special-shaped breach of polygon of non-regular polygon, dysmorphism joint 5 matches with the size and the shape of special-shaped breach. Through this mode, the personnel must use special-shaped joint 5 just can rotate special-shaped bolt to because special-shaped breach and special-shaped joint 5 are non-regular polygon, must just can insert special-shaped joint in special-shaped breach in the specific position, increased the specialty of its use, consequently this application special-shaped spanner should give the professional use when using, and when not using, should give the special messenger and take care, through this mode, can solve the problem that ordinary personnel can open at will, dismantle high tension switchgear using conventional instrument, thereby guarantee personnel and equipment's safety.
Example 1
In the embodiment, the handle 3 and the special-shaped joint 5 are of an integrated structure and are integrally cast by 28 round steel, and in order to ensure that a professional can rotate the wrench more easily when using the wrench, the handle 3 and the special-shaped joint 5 are in non-coaxial connection; more specifically, the handle 3 and the special-shaped joint 5 are vertically connected, and when the handle and the special-shaped joint 5 are vertically connected, the technical effect of saving labor is achieved.
Example 2
On the basis of embodiment 1, as a difference, the handle 3 and the special-shaped joint 5 in this embodiment are of a non-integrated structure, and the handle 3 and the special-shaped joint 5 are connected through a screw thread, so that the advantages of this arrangement are that: handle 3 and dysmorphism joint 5 can be dismantled when not using to deposit special locker side by side in, through this mode, can reduce the volume size of accomodating the locker of this spanner, reinforcing practicality.
Example 3
On the basis of embodiment 2, for making things convenient for the manufacturing and processing of special-shaped joint 5 and nut, each limit junction of special-shaped breach is the fillet, and this setting still is favorable to the dispersed structure internal stress, promotes life to be favorable to conveniently inserting special-shaped joint 5 in the special-shaped breach. But in order to ensure that the special-shaped joint 5 cannot slip at the fillet when being rotated, on the basis, the fillet radian is between 0.1 and 0.2 rad.
Example 4
On the basis of the embodiment 3, in order to facilitate the rotation of the handle 3 by a person, the surface of the handle 3 is provided with anti-skid protrusions so as to increase the friction force of the person holding the handle 3 when rotating the handle 3, thereby achieving the effects of labor saving and skid prevention; in addition, the handle 3 can be covered with a rubber anti-slip sleeve to achieve the same effect.
Example 5
On the basis of embodiment 4, dysmorphism spanner is equipped with screw cover 4 in the dysmorphism connects 5 outsides, screw cover 4 is the ring cylindricality, can avoid dysmorphism to connect 5 to collide with the stereoplasm object, causes 5 fins of dysmorphism joint, deformation, simultaneously when using, because dysmorphism connects 5 to be irregular polygon, consequently is difficult to the disect insertion, has increased the degree of difficulty that ordinary personnel used this dysmorphism spanner, further increases the degree of difficulty that ordinary personnel opened high tension switchgear. On the basis, the nut 2 is cylindrical, the special-shaped notch is formed in the middle of the nut 2, and the inner diameter of the screw sleeve 4 is larger than the outer diameter of the nut 2. The screw cap 4 can be fixed to the outside of the screw 1 by welding.
Example 6
On the basis of embodiment 5, the shape of the special-shaped joint 5 and the special-shaped gap in this embodiment is an irregular triangle, and compared with embodiment 1, the production difficulty of the special-shaped joint 5 and the special-shaped gap in this embodiment is small, and the production cost is low.
The above are only some preferred embodiments of the present invention, and it should be noted that the above preferred embodiments should not be considered as limitations of the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and enhancements can be made without departing from the spirit and scope of the invention, and such modifications and enhancements are intended to be within the scope of the invention.
