Abstract
The utility model discloses a connection structure for epoxy insulator spindle and metalwork, it includes insulator spindle sleeve and metalwork, and the telescopic tip of insulator spindle is inserted to the one end of metalwork, and the other end of metalwork is equipped with the threaded rod of connecting usefulness, the metalwork is connected with insulator spindle sleeve interference fit, has cyclic annular flange in the centre of metalwork, and the flange is hugged closely in the telescopic tip of insulator spindle, is equipped with the radial through-hole of intercommunication in the centre of insulator spindle sleeve and metalwork, has the pin in the through-hole. Through increasing the pin fastening in the centre of epoxy insulator spindle and metalwork, can effectually avoid the emergence that drops, firm in connection is reliable, has gained fine effect.
Description
Technical Field
The utility model relates to an epoxy insulator spindle especially relates to a connection structure that is used for epoxy insulator spindle and metalwork, belongs to transmission equipment and overhauls instrument technical field.
Background
In electric power tool, often will use the connecting piece structure of epoxy insulating part and metal, these structures are in the use, owing to there is the ageing of epoxy insulating part, in being connected with the metalwork, can take place the phenomenon that drops, and on the other hand, epoxy insulating part also has the problem that joint strength is low with the connecting piece of metal, in the use, also can lead to dropping and have the potential safety hazard, leads to the emergence of incident such as equipment unsettled, short circuit fault.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: the utility model provides a connection structure for epoxy insulator spindle and metalwork, through increase the pin fastening in the centre of epoxy insulator spindle and metalwork, can effectually avoid the emergence that drops, firm in connection is reliable, the effectual problem of having solved the aforesaid existence.
The technical scheme of the utility model is that: the utility model provides a connection structure for epoxy insulator spindle and metalwork, it includes insulator spindle sleeve and metalwork, and the telescopic tip of insulator spindle is inserted to the one end of metalwork, and the other end of metalwork is equipped with the threaded rod of connecting usefulness, the metalwork is connected with insulator spindle sleeve interference fit, has annular flange in the centre of metalwork, and the flange hugs closely in the telescopic tip of insulator spindle, is equipped with the radial hole of intercommunication in the centre of insulator spindle sleeve and metalwork, and there is the pin in the radial hole.
The pin is in an expansion screw or bolt structure, and sealing structure glue is arranged at the connecting thread.
The utility model has the advantages that: compared with the prior art, adopt the technical scheme of the utility model, through adopting spiral rotation to reach the fastening, form a fastener like this, utilize the physics and the mathematical principle of the circular rotation of italic and frictional force in kind, thereby fasten the device gradually and make the object fastening. Another method is to use rivet fixing or cross bolt. In order to avoid the falling off of the metal piece and the epoxy resin insulating rod sleeve, the rivet is fixed on the metal piece to prevent the falling off by the stress of the shell of the epoxy resin insulating rod sleeve, so that the safety effect during operation is achieved, meanwhile, the rivet is connected by using special metal fixing glue, and the looseness prevention is achieved by using a method of increasing the friction force between a thread space and a bolt (screw) head and the end face of a nut, so that the aim of preventing the fastening from falling off is achieved. The requirement of safe work is really met, safety accidents are avoided, and a good using effect is achieved.

fig. 2 is a side view of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
Example 1: as shown in the accompanying drawings 1-2, a connection structure for an epoxy resin insulating rod and a metal piece comprises an insulating rod sleeve 4 and a metal piece 1, wherein one end of the metal piece 1 is inserted into the end part of the insulating rod sleeve 4, a threaded rod 2 for connection is arranged at the other end of the metal piece 1, the metal piece 1 is connected with the insulating rod sleeve 4 in an interference fit manner, an annular flange 6 is arranged in the middle of the metal piece 1, the flange 6 is tightly attached to the end part of the insulating rod sleeve 4, a communicated radial hole 3 is arranged in the middle of the insulating rod sleeve 4 and the metal piece 1, and a pin 5 is arranged in the radial hole 3.
Further, the pin 5 is in an expansion screw or bolt structure, and sealing structure glue is arranged at the connecting thread.
The fastening is achieved by adopting spiral rotation, so that a fastening piece is formed, and the physical and mathematical principles of italic circular rotation and friction of an object are utilized to fasten the device step by step so as to fasten the object. Another method is to use rivet fixing or cross bolt. In order to avoid the falling off of the metal piece and the epoxy resin insulating rod sleeve 4, the rivet is fixed on the metal piece by the stress of the shell of the epoxy resin insulating rod sleeve 4 to prevent the metal piece and the epoxy resin insulating rod sleeve from falling off, so that the safety effect during operation is achieved, meanwhile, the metal piece and the epoxy resin insulating rod sleeve are connected by using special metal fixing glue, and the looseness prevention is achieved by using a method of increasing the friction force between a thread space and a bolt (screw) head and the end surface of a nut, so that the purpose of preventing the fastening from. The requirement of safe work is really met, and safety accidents are avoided.
The parts of the present invention not described in detail are the known techniques of those skilled in the art. Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
