Description

Technical Field

[0001] This utility model relates to the field of industrial chassis technology, and in particular to a push-type board-assisted chassis device. Background Technology

[0002] Industrial chassis, also known as computer chassis for the industrial control industry, are typically used in harsh environments. Currently, industrial chassis are trending towards miniaturization, which places higher demands on the utilization of internal space. For boards that need to be plugged in and out, it's wasteful to leave enough space inside the chassis for a hand or other tools (handles) to fit, especially if the space isn't utilized efficiently.

[0003] Chinese patent document CN210381680U discloses a push-pull assembly, a printed circuit board, and a fixing screw. The push-pull assembly includes a panel assembly, a torsion spring, a wrench, and a rivet stud. The panel assembly includes a panel with a lock-up screw, a rivet through hole, a torsion spring limit stop, a rivet stud, and an elastic shield. The torsion spring includes a torsion shaft and a torsion arm. The wrench includes a countersunk platform, a through hole, an arm, a pull-up lever support boss, a push-up lever hook, a torsion arm pre-embedded groove, a limit block, and a torsion spring pre-embedded countersunk platform. The countersunk platform and the through hole are connected to the rivet stud, which is connected to the rivet through hole. The rivet stud includes a head, a shaft cylinder, a rivet cylinder, and a threaded hole.

[0004] When using the aforementioned industrial control chassis for plug-in board installation, a series of tools such as wrenches are required, and tools are needed to pull out the boards. This makes it difficult to control the force on the internal boards and can easily damage the connectors between the boards and the backplane. As a result, the chassis has low applicability and cannot meet the actual needs of use. Utility Model Content

[0005] The purpose of this utility model is to provide a press-type board-type booster box device to solve the above-mentioned technical problems.

[0006] This utility model provides a push-type board-assisted chassis device, including a chassis body and a plug-in assembly with boards. The plug-in assembly is inserted into the chassis body and is detachably connected to the chassis body via a lock-up bolt mounted on the plug-in assembly. A booster for pushing out the plug-in assembly is rotatably mounted inside the chassis body. A striker extending into the chassis body and corresponding to the drive head of the booster is slidably mounted on the lock-up bolt. The inner end of the striker is slidably connected to the drive head of the booster and pushes the booster to rotate.

[0036] Example 1

[0037] like Figures 1-8 As shown:

[0038] A push-type board booster chassis device includes a chassis body 1 and a plug-in assembly 4 with boards 5. The plug-in assembly 4 is plugged into the chassis body 1, and the connection end 51 of the boards 5 is plugged into a high-speed connector 9 inside the chassis body 1.

[0039] like Figure 2 As shown, the chassis body 1 includes a chassis shell 11 and a chassis cover 12, which are detachably connected by flat-head bolts. The chassis shell 11 is provided with ventilation holes 13.

[0040] The side of the chassis shell 11 is provided with a mounting groove 21, and the inner side of the mounting groove 21 is provided with a plug groove 22, a threaded hole 23 and a through hole 24.

[0041] like Figure 3 As shown, the plug-in assembly 4 includes a panel 42 and a mounting plate 41 for mounting the card 5. The mounting plate 41 and the card 5 are plugged into the plug-in slot 22, and the panel 42 is embedded in the mounting slot 21.

[0042] The connection end 51 of the board 5 is located at the end of the board 5 away from the panel 42. The length of the tray 41 does not exceed the length of the board 5, ensuring that the connection end 51 and the high-speed connector 9 can be stably connected. This avoids the situation where the connection end 51 of the board 5 and the high-speed connector 9 cannot be properly plugged in after the plug-in assembly 4 is inserted due to the tray 41 being too long.

[0043] The plug-in assembly 4 is detachably connected to the chassis body 1 by a non-detachable bolt 6 installed on the plug-in assembly 4.

[0044] like Figure 4 As shown, the non-detachable bolt 6 includes a rotating part 61, an operating part 62, and a threaded part 63. The rotating part 61, the operating part 62, and the threaded part 63 are integrally formed. The rotating part 61 of the non-detachable bolt 6 is rotatably mounted on the panel 42. The threaded part 63 of the non-detachable bolt 6 is correspondingly provided with the threaded hole 23 and is threadedly connected.

[0045] The non-detachable bolt 6 has a coaxial sliding groove through which a striker 7 is slidably installed. A limit block 71 is provided at the tail end of the striker 7.

[0046] like Figure 5 and Figure 6 As shown, a booster 3 for pushing out and pulling out the assembly 4 is rotatably installed inside the chassis body 1.

[0047] The booster 3 is vertically arranged on both sides of the insertion slot 22. The booster 3 has a crescent-shaped structure and a protrusion 33 is provided on the booster 3. The protrusion 33 is rotatably connected to the chassis body 1 through the rotating shaft 37.

[0048] A slot 34 is provided on the protrusion 33, and a reset torsion spring 35 is placed in the slot 34. An opening 36 is provided in the slot 34 near the inner wall of the chassis 11. A rotating shaft 37 is provided through the center area of ​​the reset torsion spring 35. One torsion arm of the reset torsion spring 35 is locked in the slot 34, and the other torsion arm passes through the opening 36 and abuts against the inner wall of the chassis 11 for support.

[0049] The inner end of the striker 7 extends into the interior of the chassis body 1 and is correspondingly and slidably connected to the drive head 31 of the booster 3. The drive head 31 of the booster 3 has a concave arc surface. The striker 7 moves inward to contact the drive head 31 and pushes the booster 3 to rotate. The inner end of the striker 7 slides relative to the drive head 31.

[0050] The drive head 31 of the booster 3 is correspondingly set with the threaded hole 23, and the booster head 32 of the booster 3 is correspondingly set with the through hole 24; the booster head 32 of the booster 3 extends outward through the through hole 24 to push the panel 42 outward and thus the plug-in component 4 is pushed out.

[0051] Work process:

[0052] When board 5 needs to be installed, such as Figure 7 As shown, the tray 41 and the plate 5 are placed into the insertion slot 22, pushing the panel 42 gradually closer to the mounting slot 21; due to the sliding connection between the striker 7 and the captive bolt 6, the striker 7 is fixed relative to the booster 3 until the panel 42 is embedded in the mounting slot 21; the operating part 62 of the captive bolt 6 is screwed on, and the threaded part 63 of the captive bolt 6 is threadedly connected to the threaded hole 23, and the plate 5 is installed. The overall mechanism is as follows. Figure 6 As shown.

[0053] When board 5 needs to be removed, such as Figure 8 As shown, rotating the operating part 62 of the non-detachable bolt 6 causes the threaded part 63 of the non-detachable bolt 6 to separate from the threaded hole 23; pressing the limiting block 71 at the tail end of the impact pin 7 causes the impact pin 7 to move towards the booster 3, and the booster 3 rotates clockwise; at the same time, the inner end of the impact pin 7 slides relative to the drive head 31 of the booster 3; the booster head 32 of the booster 3 pushes the panel 42 outward through the through hole 24, and the board 5 is pushed out.

[0054] As the booster 3 rotates, the torque arm of the return torsion spring 35, which is in contact with the chassis housing 11, is compressed. When the striker 7 separates from the chassis body 1 along with the insertion / removal assembly 4, the booster 3 rotates counterclockwise under the force of the return torsion spring 35 restoring its deformation, returning to its original position. Figure 7 The initial state.

[0055] Example 2

[0056] like Figures 9-12As shown, two clamping components are installed in the insertion slot 22 for mutual use, and the clamping components are located below the high-speed connector 9.

[0057] The clamping assembly includes a rotating seat 81 installed on the inner wall of the insertion slot 22, a vertically arranged connecting shaft 82 rotatably sleeved inside the rotating seat 81, and a support arm 83 and a rotating arm 84 linked to the support arm 83 mounted on the connecting shaft 82.

[0058] An auxiliary torsion spring is provided between the rotating seat 81 and the connecting shaft 82.

[0059] The end of the rotating arm 84 is hinged to a support pad 86 via a connecting lug 85, and the end of the support arm 83 is provided with a roller 87.

[0060] The initial state of the clamping assembly is that the rotating arm 84 is located near the inner wall of the insertion slot 22, and the support arm 83 is tilted towards the opening of the insertion slot 22.

[0061] When the board 5 is inserted into the insertion slot 22, the insertion assembly 4 enters the insertion slot 22. The insertion assembly 4 first rolls into contact with the roller 87 of the support arm 83. The insertion assembly 4 continues to advance, pushing the support arm 83 to rotate into a straight state. Then, the support arm 83 drives the rotating arm 84 to rotate through the connecting shaft 82 until the support pad 86 contacts the side of the insertion assembly 4, thus completing the clamping and fixing of the insertion assembly 4.

[0062] When the board 5 is pulled out of the insertion slot 22, under the force of the auxiliary torsion spring restoring its deformation, the auxiliary torsion spring drives the support arm 83 to rotate back to the initial state. At the same time, the rotating arm 84 provides an outward push force for the insertion assembly 4. Similarly, the rotating arm 84 rotates accordingly, and the support pad 86 no longer contacts the side of the insertion assembly 4, and the insertion assembly 4 is successfully separated.

[0063] By incorporating clamping components, unstable installation of plug-in components and the occurrence of wobbling are prevented, thus improving the convenience and accuracy of installation.

[0064] Example 3

[0065] like Figure 13 As shown, this device can also provide multiple heat dissipation fins 43 between the tray 41 and the board 5 to further help dissipate heat from the board.

[0066] The tray 41, the card 5 and the heat sink 43 can be connected by bolts or glue. The specific connection method can be selected according to the actual situation and there are no restrictions.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
