[0002] At present, electronic products are showing a development trend of field replaceable modularization, which puts forward higher requirements on the replacement speed of modules. The disassembly of modules mainly depends on the locking device on them. However, the traditional locking method has the following disadvantages.

[0003] At present, replaceable modules on the rack of electronic equipment use a puller and a locking device, which are separate. The puller is installed on the end face of the module and the rack is plugged in and out through the action of a lever, and the locking device is fixed on the module, similar to a lead screw and nut structure. When the lead screw is rotated with a tool, the movement of the nut causes the locking device to expand or contract. After expansion, the locking device is pressed against the rack, and the module is locked to the rack by friction. Another type is an airborne electronic module plug-in and locking puller, which relies on the cooperation of a puller rod, a spring, a wedge block, etc. to achieve tool-free module plug-in and pull-out, but the puller has a short force arm, which is more laborious or impossible to lock for modules with large plug-in and pull-out locking forces.

[0056] Specifically, in this embodiment, the mounting bracket 1 is designed to be in the shape of a handle, and the mounting bracket 1 is set on the module through fasteners (such as fastening screws and other structural parts) to facilitate the insertion, removal and transportation of the module; at the same time, an accommodating groove 103 is set in the mounting bracket 1 to form a storage space for the sliding block 2, the pressure rod 3 and the locking hook 4.

[0057] In addition, by providing connecting parts 101 at both ends of the main body of the mounting bracket 1 and opening a countersunk hole between the connecting part 101 and the sliding block 2, a receiving cavity for receiving the coil spring is formed to limit its radial movement so that the coil spring can only move in the axial direction;

[0058] At the same time, an ear 102 is provided on the connecting portion 101, and a strip hole 106 is opened on the ear 102, so that the pressure rod 3, the sliding block 2 and the first rotating shaft 8 have a movement amount in the locking direction, and the final locking state is maintained by the elastic force of the coil spring. The spring expansion and contraction, and the movement of the pressure rod 3 and the sliding block 2 jointly provide an adaptive locking method for the equipment locking, which can eliminate the adverse effects caused by errors such as processing and assembly in the locking direction.

[0059] In some embodiments, Figure 6 As shown, the hook-shaped structure is a first locking tongue 301, and the first locking tongue 301 is buckled and connected with the locking hook 4;

[0060] The other end of the pressure rod 3 is provided with a U-shaped groove 302, and a locking pressing surface 303 and an auxiliary pulling surface 304 are formed in the U-shaped groove 302.

[0061] The second elastic member 6 is installed in the accommodating groove 103 through the connecting member. An inner groove 305 for accommodating the connecting member is provided on the inner side of the pressure rod 3, so as to avoid the connecting member when the pressure rod 3 is recovered to the accommodating groove 103. The second elastic member 6 is a leaf spring.

[0062] An end of the pressing rod 3 close to the first locking tongue 301 is formed with a pressing surface 306 protruding outward.

[0063] Specifically, in the embodiment, one end of the pressure rod 3 is designed to be a U-shaped groove 302, and a locking pressing surface 303 and an auxiliary extraction surface 304 are formed in the U-shaped groove 302. Specifically, for the locking pressing surface 303, when the quick-insert lock device is locked, the locking pressing surface 303 is pressed and locked with the corresponding surface of the block 11 of the frame or the base; and for the auxiliary extraction surface 304, when it is unlocked, the auxiliary extraction surface 304 contacts with the corresponding surface of the frame or the base and turns to the pressure rod 3, and the auxiliary module is pulled out through the lever principle.

[0064] In this embodiment, one end of the pressure rod 3 is also ergonomically designed. By providing a pressing surface 306 protruding outward at one end of the pressure rod 3 close to the first locking tongue 301, the finger can press comfortably. When locking, the pressure rod 3 can be easily pressed into the lock hook 4 with the finger.

[0065] The inner wall surface of the first locking tongue 301 is a self-locking inclined surface, and cooperates with the lock hook 4 to form a self-locking structure to prevent it from springing open; the outer wall surface of the first locking tongue 301 is a pressed-in curved surface. When locking, the lock hook 4 is squeezed, and after the lock hook 4 opens a certain angle, the pressure rod 3 enters the lock hook 4. During the locking and unlocking process, the pressure rod 3 acts as a lever rotating around the first rotating shaft 8, and the resistance position is at the locking pressing surface 303 (when locking) and the auxiliary extraction surface 304 (when unlocking), the fulcrum is at the through hole position, and the driving force is at the pressing surface 306 (when locking) or the rod body away from the through hole (when unlocking).

[0066] In some embodiments, Figure 7 and Figure 8 As shown, the lock hook 4 is rotatably arranged in the accommodating groove 103 through the second rotating shaft 9, and a limiting rib 401 is provided at one end of the lock hook 4 close to the second rotating shaft 9, and a third elastic member 7 is respectively installed in the area formed on both sides of the limiting rib 401, and the third elastic member 7 is a torsion spring, and the two third elastic members 7 are both arranged on the second rotating shaft 9;

[0067] A limiting protrusion 402 is provided on the lock hook 4, and two bending parts of the main body of the mounting bracket 1 are respectively provided with limiting grooves 107 for limiting the limiting protrusion 402;

[0068] The lock hook 4 is provided with a second lock tongue 403 that cooperates with the first lock tongue 301 , and one end of the lock hook 4 close to the second lock tongue 403 is also provided with a lever 404 .

[0069] Specifically, in this embodiment, the lock hook 4 is rotatably arranged in the accommodating groove 103 through the second rotating shaft 9, and a limiting rib 401 is arranged on the lock hook 4, and the areas formed on both sides of the limiting rib 401 are respectively equipped with torsion springs, and the torsion springs are sleeved on the second rotating shaft 9. At the same time, a limiting protrusion 402 is arranged on the lock hook 4 to cooperate with the limiting groove 107 arranged on the mounting bracket 1 to limit the rotation range of the lock hook 4.

[0070] The second lock tongue 403 provided on the lock hook 4 is formed with a pressing bevel and a self-locking bevel. Specifically, with respect to the pressing bevel, when the pressure rod 3 is pressed into the lock hook 4, the pressing bevel is subjected to a force F1, causing the lock hook 4 to rotate and bounce open until the pressure block is completely pressed into the lock hook 4. The lock hook 4 recovers under the action of the torsion spring, thereby locking the pressure rod 3; with respect to the self-locking bevel, after the pressure rod 3 is completely pressed into the lock hook 4, a corresponding self-locking bevel is provided on the pressure rod 3, and the two bevels cooperate with each other to form a self-locking structure.

[0072] like Fig. 9As shown, the device is a locking process, and only the single-side locking process is illustrated in the figure. Push the module with the quick-insert lock device into the base or rack, and apply pressure to the pressing surface 306 of the pressure rod 3 by hand. The locking pressing surface 303 of the pressure rod 3 contacts and presses the corresponding surface of the block 11 of the base or rack. Continue to apply force, and the pressing curved surface of the pressure rod 3 presses the pressing inclined surface of the lock hook 4. Continue to apply force until the pressure rod 3 is completely pressed down. At the same time, the lock hook 4 automatically rebounds under the action of the torsion spring to complete the locking. At this time, the self-locking inclined surface of the pressure rod 3 is in close contact with the self-locking inclined surface of the lock hook 4, and the direction of the interaction force forms a certain angle with the locking direction of the module, forming a self-locking state, and completing the locking process.

[0073] like Fig.10 As shown, the device is an unlocking process, and only the single-side unlocking process is illustrated. When unlocking is required, the lever 404 on the lock hook 4 is pushed by hand to open a certain angle until the pressure rod 3 automatically pops open under the action of the leaf spring, completing the first step, and then releasing the lever 404, pulling the pressure rod 3 by hand, the auxiliary pulling surface 304 of the pressure rod 3 contacts the response surface of the stopper 11 of the rack or base, and under the action of the lever, the module is easily pulled out of the rack to complete the unlocking process.

[0074] like Figures 11 to 13 The figure shows a working schematic diagram of the present application, which illustrates three states, namely, the pulled-out state, the inserted state, and the locked state. The stopper 11 is fixedly mounted on the frame or the base, and the contact portion with the top of the pressure rod 3 is designed as a U-shaped groove 302. The module needs to be limited by manual operation. Disassembly process: open the lock hook 4 directly by hand (no tools are required), the pressure rod 3 will automatically pop open due to the built-in elastic device, and the module will be pulled out. Installation process: insert the module, push the pressure rod 3 directly by hand, and the lock hook 4 will automatically close.
