Abstract
The invention discloses a spring installing fixture for a ground switch. The spring installing fixture comprises a sleeve of which one end is enclosed and the other end is open, wherein a check block capable of moving forwards and backwards in the sleeve is arranged in the sleeve; a threaded hole is formed in the enclosed end of the sleeve; a screw rod passes through the threaded hole and is connected with the check block in the sleeve; a blocking hook is arranged at the front end of the sleeve; a guide hole for mounting a spring is formed in the sleeve. After the adoption of the structure, when the spring installing fixture needs to be used, the spring is arranged in the guide hole, and the screw rod is used for driving the check block to move forwards in order to compress the spring, so that the compressed spring can be easily arranged at the spring mounting position of the ground switch; the spring installing fixture is simple and reasonable in structure, is reliable and convenient to operate, and meets the requirement of rapid spring installation; the working efficiency is increased; meanwhile the operation safety is very high, and the spring is prevented from injuring people by being ejected out of the ground switch in an installing process.
Description
Technical field
The present invention relates to the aid that a kind of earthed switch parts are installed, specifically a kind of spring fitting fixture of earthed switch.
Background technology
Earthed switch all will each be installed by parts in installation process, but because the spring of earthed switch is larger, elastic force is also larger, the installation of spring in earthed switch is all installed in compressive state, its installation process is comparatively loaded down with trivial details, and install very difficult, not only make its operating efficiency lower, and the unreliable spring that easily makes of installation method ejects the generation causing casualty accident in installation process in earthed switch.
Summary of the invention
It is simple that the technical problem to be solved in the present invention is to provide a kind of structure, easy to operate, can meet the spring fitting fixture of the earthed switch of spring Fast Installation demand.
In order to solve the problems of the technologies described above, the spring fitting fixture of earthed switch of the present invention, comprise an one end to close, the sleeve that the other end opens wide, be provided with one piece of block that can move forward and backward in sleeve in sleeve, the blind end of sleeve is provided with screwed hole, and a screw rod is connected with the block in sleeve through screwed hole, the front end of sleeve is provided with gear and hooks, and is provided with the pilot hole for settling spring in sleeve.
The rear end of described screw rod is connected with the rocking handle that block can be driven to advance or retreat.
The rear end of described block is provided with spherical hollow space, and the front end of screw rod is provided with the bulb matched with spherical hollow space.
The front end of described block is provided with groove.
After adopting above-mentioned structure, due to the block arranged in sleeve and the screw rod be connected with block, the front end of sleeve is provided with gear and hooks, when it is desired to be used, spring is placed in pilot hole, utilizing screw drive block to advance just can by spring-compressed, position settled by the spring that just easily the spring after compression can be placed in earthed switch thus, it is simple and reasonable, operation is reliable convenient, meet the demand of spring Fast Installation, improve operating efficiency, the security simultaneously operated is very high, avoid spring in installation process, in earthed switch, eject the generation causing casualty accident.
