Description
Technical Field
The invention relates to the technical field of auxiliary tools of electronic equipment, in particular to an electronic module extractor.
Background
Most of replaceable electronic modules on a rack of electronic equipment use a puller, when the conventional single-claw puller is used in the electronic module with larger thickness, the single-claw puller arranged in the middle of the electronic module easily causes inconsistent stress at the upper end and the lower end of the electronic module, so that the electronic module deflects and inclines, and at the moment, the electronic module is pulled out outwards, the friction between a sliding rail of the electronic module and a sliding rail on the rack is increased easily, and the electronic module is difficult to pull out from the rack.
Disclosure of Invention

the device comprises a roller, a pull-out body, a fixed stop block, a sliding hole, a locking block, a spring, a locking block and a fixing plate, wherein the end, far away from the roller, of the pull-out body is fixedly connected with the fixed stop block, the sliding hole is formed in the inner part, close to one end of the fixed stop block, of the pull-out body along the length direction of the pull-out body, one end of the sliding hole is a blind end, the other end of the sliding hole penetrates through the pull-out body along the direction far away from the roller, the sliding hole is in sliding connection with the locking block, the spring is arranged in the sliding hole, one end of the spring is fixedly connected with the blind end of the sliding hole, the other end of the spring is fixedly connected with the locking block, and when one end, far away from the spring, of the locking block extends out of the sliding hole, the locking block forms a U-shaped opening matched with the fixing plate on the electronic module, and the end surface, close to the electronic module, of the locking block is provided with an inclined surface;
a slot for communicating the sliding hole with the external space of the pulling body is horizontally arranged on the pulling body, a moving block is arranged in the slot, one end of the moving block is fixedly connected with the locking block, and the other end of the moving block is a free end which extends out of the slot;
the handle is vertically arranged, the upper end of the handle is fixedly connected with the free end of the moving block on the upper pulling body, and the lower end of the handle is fixedly connected with the free end of the moving block on the lower pulling body.
Compared with the existing single-claw extractor, the basic scheme of the invention has at least the following beneficial effects:
1. the lifting bodies in the basic scheme are arranged in an up-and-down number of 2, the lifting bodies which are distributed up-and-down are respectively connected with the upper surface and the lower surface of the electronic module with larger thickness in a rotating way through the rotating shaft, the electronic module is provided with a sliding rail which is matched with the sliding rail, the frame is also provided with a groove which is used for containing the roller to rotate around the rotating shaft, when the handle is held to move towards the direction close to the roller to enable the locking block to retract into the sliding hole, the locking block cannot form a U-shaped opening matched with the fixing plate on the electronic module with the fixing block, the handle is pulled outwards, the roller rotates around the rotating shaft and extrudes the rear side wall of the groove on the frame, and the counter force of the frame to the lifting bodies enables the electronic template to slide out of the frame to the front of the frame.
2. Because the upper and lower pulling bodies are stressed simultaneously when the handle is pulled, the tensile forces born by the upper and lower ends of the electronic module are consistent, the phenomenon that the friction force between the sliding rail on the electronic module and the sliding rail on the frame is increased can not occur, and the electronic module is convenient to separate from the frame quickly.
3. The puller also has the function of enabling the electronic module to be quickly connected and locked with the rack, a locking device for locking the electronic module with the rack is not needed to be additionally arranged, when the sliding rail on the electronic module is inserted into the sliding rail on the rack, the handle is pushed towards the direction close to the electronic module, at the moment, the roller presses the front side wall of the groove on the rack to enable the whole puller to form a stress application lever to increase the thrust to the electronic module, under the action of the inclined plane of the locking block and the fixed plate on the electronic module, the locking block firstly retracts into the sliding hole and then stretches out of the sliding hole to form a U-shaped opening matched with the fixed plate with the fixed block, and after the locking block stretches out of the sliding hole, the electronic module cannot slide out of the rack, so as to play a role in locking the electronic module.
