Electrodynamic vibrator with case structure preventing burnout

Abstract

The invention provides an electric vibrator for preventing burning and a shell structure thereof. The electric vibrator comprises a reset spring, an electrical box, a bonding post and a spring installation seat, wherein four guide rods are pasted with the circumference of a junction box electrically connected with an outer end of a vibrator main body, a square shell-structure fire extinguishing seat is matched in a penetrating way by a matching mode of the four guide rods and four guide sleeve, limitation seats are arranged at outer ends of the guide rods and are used for allowing the fire extinguishing seat to move and limit, a press sleeve is further pasted with a bottom surface of the fire extinguishing seat, a fire source on the junction box can be controlled, and the safety coefficient during the application process of the vibration motor is improved; since a press seat pasted with the bottom of the fire extinguishing seat is of an air bag structure having buffer and exhaust functions, the fire source can be rapidly extinguished by an airflow effect at the moment when the fire extinguishing seat is bucked to the junction box, so that the press seat originally for generating abuffer force is more reasonable in structure when the fire extinguishing seat is contacted with an outer wall of the vibration motor.

Description

technical field [0001] The invention belongs to the technical field of vibration motor structure, and more specifically relates to an electric vibrator with a shell structure that prevents burning. Background technique [0002] The traditional vibration motor is a kind of electric vibrator, which is installed on the equipment, such as the vibrating screen of the equipment, the discharge hopper, etc., so that these mechanisms can produce vibration effects and achieve the expected results. Due to its simple structure, only Fixing on the mechanism with bolts can make the mechanism vibrate. Therefore, it has been widely used in the field of small product production. Its structure is: the vibration motor is installed at both ends of the rotor shaft. The eccentric block uses the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block to obtain the exciting force. [0003] Based on the above description of the vibration motor, it is found that w...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides an electric vibrator with a shell structure that prevents burning, so as to solve the problem that the wiring connection posts or wiring contacts on the existing vibration motor junction box are affected by external factors, such as excessive current, Or when there is an overload, a current spark will appear at the terminal of the two contacts. When the sparks of the two contacts collide, the junction box will be burned and a fire will occur. If this phenomenon occurs, if it is not handled in time, there will be certain safety hazards. the problem that caused the accident
