Description

Technical Field

[0001] The present application relates to a quick plug-in and locking extractor for electronic modules that can be operated without tools, and specifically to a handle-type module plug-in and locking extractor and a module plug-in and locking method, which have both power-assisted plug-in and pull-out and locking and stopping functions. Background Art

[0002] With the development of integrated electronic systems, highly integrated field-replaceable electronic modules LRM (LineReplaceable Module) are increasingly used in various platforms such as land, sea, air and space. In order to quickly respond to field maintenance needs, improve field replacement efficiency, and enable LRM modules to be quickly installed or removed from the rack, a device with assisted plugging and locking functions is required. However, most LRM modules currently use separate plugging and locking devices. The plugging and locking devices are independent of each other and are installed on the front panels and ribs on the left and right sides of the LRM module. This combination is relatively traditional and time-consuming, and the locking device requires special equipment to provide support to complete the locking and loosening operations.

[0003] The patent (CN110300505) proposes an airborne electronic module quick plug-in and lock-in puller, which solves the problem that the existing electronic module pullers cannot take into account the module locking. However, when in use, one needs to be installed on each of the left and right front panels of the LRM module. The puller is a single-hook puller and needs to be operated separately. When plugging and unplugging the LRM module, you need to first hold the LRM module body by hand to pre-plug the module, and then operate the pullers on the left and right sides respectively. This method of directly holding the LRM module by hand may cause scratches on the smooth surface of the LRM module. On the other hand, when the meshing force between the LRM module connector plug and the rack connector socket is large or there is no operating space on both sides of the LRM module, the smooth surface of the LRM module cannot be held, and the puller rod of the single-hook puller is short and cannot provide sufficient leverage, resulting in the LRM module being unable to be pulled out. Summary of the invention

[0004] The purpose of this application is to provide a convenient, time-saving, and labor-saving handle-type module plug-in locking extractor and module plug-in locking method that can take into account auxiliary plug-in and pull-out and tool-free maintenance to complete locking and stopping, thereby solving the operational problems existing in existing LRM module extractors.

[0005] The purpose of this application is achieved through the following technical solutions:

[0006] A handle-type module plug-in locking extractor comprises a handle base, with extractor rods, wedge-shaped top blocks and corner locks on both sides of the handle base, the outer end of the extractor rod is a rod jaw, the middle part of the extractor rod is hinged to the handle base, the inner end of the extractor rod is a rod lock, the corner lock is hinged to the handle base, and the rod lock of the extractor rod on one side is engaged with the lock of the corner lock on the opposite side.

[0007] Furthermore, the handle base is provided with a first handle latch hole and a second handle latch hole, the pulling rods on both sides are provided with rod latch holes and the holes are opposite to each other, the first handle latch hole is opposite to the rod latch hole, the corner locks on both sides are provided with lock latch holes, and the second handle latch hole is opposite to the lock latch hole.

[0008] Furthermore, the pulling rod and the wedge-shaped top block are hinged at the vertical waist-shaped hole of the handle base through the same rotating shaft, and a compression spring is provided between the lower part of the wedge-shaped top block and the handle base.

[0009] Furthermore, the corner lock is hinged to the circular hole of the handle base via a rotating shaft, and a torsion spring is provided between the corner lock and the handle base to provide elastic force from the open position to the locked position.

[0010] Furthermore, a spring sheet is provided between the lower portion of the pulling rod and the handle base, and the spring sheet is fixed to the handle base via a screw assembly.

[0011] Furthermore, the lower part of the rod lock buckle of the pulling rod is provided with an outward rod inclined surface, the upper part of the lock buckle of the corner lock is provided with an inward locking element inclined surface, and the upper part of the inner end of the pulling rod is provided with an obstruction boss.

[0012] Furthermore, the corner portion of the corner locking piece faces the upper outer side, and the limiting boss of the corner locking piece is in limiting contact with the handle base.

[0013] A module plug-in and locking method comprises a module and a rack, and also comprises the above-mentioned handle-type module plug-in and locking puller, wherein the handle base is arranged on the module; when the module is plugged into the rack, the module ribs on the module are aligned and inserted between the rack mounting groove ribs on the rack, the rod jaws of the pull-out rod are locked with the rack stopper, and downward pressure is jointly applied to the inner ends of the pull-out rods on both sides until the rod lock buckle of the pull-out rod is locked with the lock buckle of the corner lock piece, during which the pull-out rod presses down the handle base, drives the module into the rack and the wedge-shaped top block descends, and finally the module completely enters the rack and the wedge-shaped top block is tightly supported between the module ribs and the rack mounting groove ribs; when the module is disengaged from the rack, the corner lock piece is pulled outward, so that the rod lock buckle of the pull-out rod is disengaged from the lock buckle of the corner lock piece, and the handle base is pulled to disengage the module from the rack.

[0014] Furthermore, when the module is plugged into the frame, the same rotating axis on which the pulling rod and the wedge-shaped top block are hinged descends along the waist-shaped hole of the handle base, and overcomes the elastic force of the compression spring between the lower part of the wedge-shaped top block and the handle base; when the module is disengaged from the frame, the elastic force of the compression spring causes the wedge-shaped top block to disengage from between the module ribs and the frame mounting groove ribs, and at the same time causes the rod lock buckle to disengage from the lock buckle.

[0015] Furthermore, when the module is plugged into the rack, the pull-out rod overcomes the elastic force of the spring sheet between the lower part of the pull-out rod and the handle base, and the corner lock overcomes the elastic force of the torsion spring between the corner lock and the handle base, and after the rod lock and the lock lock are locked, the elastic force of the torsion spring makes the lock tight; when the module is disengaged from the rack, the elastic force of the spring sheet causes the rod lock and the lock lock to disengage, and the elastic force of the torsion spring causes the corner lock to return to the locked position.

[0016] Beneficial effects of this application:

[0017] (1) This application can not only realize the plug-in / locking function of the LRM module, but also the handle base is installed on the front face of the LRM module, providing a hand-held grip for the body of the LRM module, facilitating the module to be taken out and transported, and avoiding direct contact with the smooth surface of the module to cause scratches and contamination. At the same time, the handle base is provided with 3 pin holes, which can respectively lock the fork-shaped extended puller rod and the corner lock on both sides of the locking puller, further ensuring that after the LRM module is inserted into the rack and locked, the puller rod will not be unhooked, causing the LRM module to loosen, and has the characteristics of compact structure, strong vibration resistance and high reliability.

[0018] (2) The fork-shaped extended lifting and pulling rod adopted in the present application rotates around the waist-round mounting hole of the handle base during the insertion and removal of the LRM module. The longer operating force arm can provide greater auxiliary force, which can effectively overcome the meshing force between the LRM module connector plug and the rack connector socket, making the entire operation process easier and can be operated with one hand, which has the advantages of being fast, convenient, time-saving and labor-saving.

DETAILED DESCRIPTION

[0029] The following non-limiting examples are provided to illustrate the present application.

[0030] Example 1

[0031] refer to Figure 1 to Figure 6 As shown, a handle type module plug-in locking extractor comprises a handle base 1, an extractor rod 2, a wedge-shaped top block 3, a corner lock 4, a rotating shaft 5, a clamping ring 6, a compression spring 7, a torsion spring 8, a spring sheet 9 and a screw assembly 10.

[0032] Both sides of the handle base 1 are provided with a pull rod 2, a wedge-shaped top block 3 and a corner lock 4. The outer end of the pull rod 2 is a rod jaw 202, which is used to engage with the frame stopper 13 and serve as a prying point during the insertion and extraction process. The inner end of the pull rod 2 is a rod lock 203, which is used to engage with the corner lock 4 in the locked state to ensure the stability of the locked state.

[0033] The middle part of the pulling rod 2 is hinged on the handle base 1, and the hinge point is used as the fulcrum of the pulling rod 2. The outer end of the pulling rod 2 is a short arm and the inner end (operating end) is a long arm, thereby forming a labor-saving lever. When plugging and unplugging, the resistance between the module and the rack acts on the labor-intensive end of the outer end, and the manually applied force acts on the labor-saving end of the inner end. The pulling rod 2 is operated to rotate around the hinge point to realize the specific plugging / unplugging / locking action.

[0034] The wedge-shaped top block 3 is arranged on the handle base 1, and the wedge-shaped top block 3 is used to tighten between the module and the rack to achieve locking. When the pull rod 2 drives the handle base 1 to move during the plugging and unplugging process, the wedge-shaped top block 3 moves synchronously, and the wedge-shaped top block 3 enters / exits between the module and the rack to achieve tightening / disengagement.

[0035] The corner lock 4 is hinged on the handle base 1, and the rod lock 203 of the lifting rod 2 on one side is engaged with the lock lock 402 of the corner lock 4 on the opposite side. When the module is fully inserted into the rack and the wedge-shaped top block 3 is tightened, the corner lock 4 is locked with the lifting rod 2 to maintain the locked state. By turning the corner lock 4, the locking between the rod lock 203 and the lock lock 402 can be released. At this time, the lifting rod 2 is in a free rotation state, and the module can be disengaged.

[0036] Example 2

[0037] refer to Figures 1 to 8 As shown, a module plug-in and locking method includes a module and a rack, and also includes the handle-type module plug-in and locking extractor of Example 1, and the handle base 1 is fixed on the module.

[0038] When the module is plugged into the rack, the module ribs 11 on the module are aligned and inserted between the rack mounting groove ribs 12 on the rack to complete the pre-installation of the module. Then the rod jaws 202 of the pull rod 2 are locked with the rack stopper 13, and downward pressure is applied to the inner ends of the pull rods 2 on both sides. The pull rods 2 rotate inward around the waist-round mounting holes of the handle base 1 to form a labor-saving lever structure until the rod lock 203 of the pull rod 2 is locked with the lock lock 402 of the corner lock 4. In this process, the pull rod 2 presses down the handle base 1, driving the module into the rack and the wedge-shaped top block 3 to descend. Finally, the module completely enters the rack and the wedge-shaped top block 3 is tightly supported between the module ribs 11 and the rack mounting groove ribs 12.

[0039] When the module is to be separated from the rack, the corner lock 4 is pulled outward to disengage the rod lock 203 of the pulling rod 2 from the lock lock 402 of the corner lock 4, and the handle base 1 is pulled to disengage the module from the rack, and the wedge-shaped top block 3 is disengaged from the module rib 11 and the rack mounting groove rib 12.

[0040] It can be seen that when the handle-type module plug-in, lock and puller of Example 1 is used to plug, pull and lock the module, the handle base provides a hand-held grip for the body of the LRM module, which facilitates the module to be taken and transported, and avoids direct contact with the smooth surface of the module to cause scratches and contamination.

[0041] The pull rod adopts a fork-shaped extended pull rod arranged symmetrically on both sides. The pull rod has a long lever arm on the handle base. The long operating lever arm can provide a large auxiliary force, which can effectively overcome the meshing force between the LRM module connector plug and the rack connector socket, making the entire operation process easier. Since the pull rods on both sides are arranged on a handle base, and the pull rods on both sides are overlapped and cross-arranged, the plugging / locking operation can be achieved with one hand, which is fast, convenient, time-saving and labor-saving.

[0042] A new type of corner lock is used to lock the pull rod, which optimizes the structural design of the handle base and the pull rod and avoids the design difficulties of miniaturization and internalization of various components brought by the spring telescopic lock. At the same time, the corner lock structure is externally positioned as a whole, which can be easily operated and the locking status of the card setting at that location can be observed, thereby optimizing the use operation.

[0043] Example 3

[0044] refer to Figure 1 to Figure 6 As shown, a handle-type module plug-in locking extractor is optimized and improved based on the handle-type module plug-in locking extractor of Example 1.

[0045] A centrally symmetrical mounting groove is provided on the handle base 1, so that the pulling rods 2, wedge-shaped top blocks 3 and corner locks 4 on both sides are also centrally symmetrically arranged on the handle base 1, and the pulling rods 2 on both sides are overlapped and cross-arranged, which is convenient for one-handed operation of the two rods, and the wedge-shaped part of the wedge-shaped top block 3 is arranged downward.

[0046] The handle base 1 is a "J" shaped structure, including a middle horizontal section, side vertical sections and edge horizontal sections. The middle horizontal section of the handle base 1 is provided with a first handle latch hole and a second handle latch hole. The first handle latch hole is located in the middle, and the second handle latch hole is located on both sides.

[0047] The pulling rods 2 on both sides are provided with rod member latch holes 201 and the holes are opposite to each other, and the first latch hole of the handle is opposite to the rod member latch hole 201. The corner locks 4 on both sides are provided with lock member latch holes 401, and the second latch hole of the handle is opposite to the lock member latch hole 401. The latch is inserted into the first latch hole of the handle and the rod member latch hole 201 at the same time, and the latch is inserted into the second latch hole of the handle and the lock member latch hole 401 at the same time, so as to realize the locking and fixing of the pulling rod 2 and the corner lock 4, and avoid unhooking in the locked state.

[0048] The pulling rod 2 and the wedge-shaped top block 3 are hinged at the vertical waist-shaped hole in the horizontal section of the edge of the handle base 1 through the same rotating shaft 5 and the clamping ring 6, so that the hinge point of the pulling rod 2 and the wedge-shaped top block 3 can move up and down synchronously relative to the handle base 1, and a compression spring 7 is provided between the spring groove at the lower part of the wedge-shaped top block 3 and the spring groove of the handle base 1.

[0049] When plugged in, the downward pressure of the pull rod 2 overcomes the elastic force of the compression spring 7, and drives the wedge-shaped top block 3 to descend together through the rotating shaft 5, so as to lock the wedge-shaped top block 3 in place. At the same time, due to the transition buffering effect of the compression spring 7, the hinge point exerts a buffering force downward on the handle base 1 and the module. When disengaging, the elastic force of the compression spring 7 causes the wedge-shaped top block 3 to directly disengage from the tightening position, and also provides a certain force for the lock of the pull rod 2 to disengage.

[0050] The corner lock 4 is hinged to the circular hole of the vertical section on the side of the handle base 1 through the rotating shaft 5 and the clamping ring 6. A torsion spring 8 is provided between the corner lock 4 and the handle base 1 to provide elastic force from the open position to the locked position, so as to keep the corner lock 4 in the locked position under normal circumstances, which is conducive to maintaining the locked state. The corner portion of the corner lock 4 extends to the upper part of the outside, which is convenient for personnel to operate and observe the state of the lock. The limiting boss 404 of the corner lock 4 is in limiting contact with the handle base 1 to keep the corner lock 4 locked in the vertical state.

[0051] The torsion spring 8 is a fan-shaped torsion spring, and the L-shaped opening end and the U-shaped end of the fan-shaped torsion spring are respectively attached to the limiting ridge 403 at the lower end of the installation hole of the corner lock 4 and the inner wall of the installation groove of the handle base 1. Under the tension of the fan-shaped torsion spring, the corner lock 4 rotates inward around the installation hole. When the limiting boss 404 is buckled at the limiting opening of the handle base 1, the corner lock 4 is always kept in an upright closed state in the normal state. When the LRM module is plugged in and locked, the conical lock buckle 402 of the corner lock 4 is tightly engaged with the tongue-shaped rod lock buckle 203 at the operating end of the pull rod 2, ensuring that the pull rod 2 does not pop out, thereby achieving the locking of the LRM module.

[0052] A spring sheet 9 is provided between the lower part of the pulling rod 2 and the handle base 1. The spring sheet 9 is fixed in the middle cavity of the handle base 1 by a screw assembly 10. The spring sheet 9 adopts a disc spring sheet with a central symmetrical structure. The spring sheets on both sides are respectively located below the inner end of the pulling rod 2, which can provide elastic support for the inner end of the pulling rod 2, making it convenient for the pulling rod 2 to pop out from the locked position.

[0053] The lower part of the rod lock 203 of the pulling rod 2 is provided with an outward rod inclined surface, and the upper part of the lock lock 402 of the corner lock 4 is provided with an inward lock inclined surface. When the pulling rod 2 is pressed down, the two inclined surfaces can push the corner lock 4 to rotate outward and open, so as to realize the automatic locking of the pulling rod 2. The upper part of the inner end of the pulling rod 2 is provided with an obstruction boss to prevent the handle base 1 from sliding to the corner lock 4. When the corner lock 4 is unlocked, the obstruction boss can be pressed with the palm of the hand at the same time to reduce the contact between the two locks and facilitate opening.

[0054] Example 4

[0055] refer to Figures 1 to 8 As shown, a module plug-in and locking method is optimized and improved based on the handle-type module plug-in and locking extractor of Example 3 and the plug-in and locking method of Example 2.

[0056] When the module is inserted into the rack, the same rotating shaft 5 that the lifting rod 2 and the wedge-shaped top block 3 are hinged to descend along the waist-shaped hole of the handle base 1, and overcomes the elastic force of the compression spring 7 between the lower part of the wedge-shaped top block 3 and the handle base 1. In this process, the lifting rod 2 presses down the handle base 1, driving the module into the rack and the wedge-shaped top block 3 to descend, and finally the module completely enters the rack and the wedge-shaped top block 3 is tightly supported between the module rib 11 and the rack installation groove rib 12.

[0057] When the module enters the rack, the downward pressure of the handle base 1 and the reaction force of the inner side of the rack stopper 13 push the LRM module to move along the rack mounting groove rib 12, so as to achieve the locking of the front and rear ends of the LRM module in the length direction. At the same time, the conical surface of the wedge-shaped top block 3 is in close contact with the module rib 11 and the inclined surface of the rack mounting groove rib 12 to generate a component force along the inclined surface, so as to achieve the locking of the left and right ends of the LRM module in the thickness direction.

[0058] When the module is separated from the rack, the elastic force of the compression spring 7 causes the wedge-shaped top block 3 to separate from between the module rib 11 and the rack mounting slot rib 12, and at the same time causes the rod lock 203 to separate from the lock lock 402.

[0059] When the module is plugged into the rack, the pull rod 2 overcomes the elastic force of the spring sheet 9 between the lower part of the pull rod 2 and the handle base 1, and the corner lock 4 overcomes the elastic force of the torsion spring 8 between the corner lock 4 and the handle base 1, so that the pull rod 2 enters the locked position. After the rod lock 203 and the lock lock 402 are locked, the elastic force of the torsion spring 8 makes the locking tight and maintains the locked state.

[0060] When the module is disengaged from the rack, the elastic force of the spring sheet 9 causes the rod lock 203 to disengage from the lock lock 402, and the elastic force of the torsion spring 8 causes the corner lock 4 to return to the locked position.

[0061] The aforementioned basic examples and their further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection in this application. In the scheme of this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.

[0062] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
