Description

Technical Field

[0001] The utility model relates to the technical field of chassis plug-in and pull-out tools, in particular to a quick plug-in and pull-out and locking mechanism for a vehicle-mounted standard plug-in box. Background Art

[0002] In modern electronic equipment, ANSI standard VPX chassis are widely used, especially in environments that require high-performance computing and processing capabilities. Such chassis are designed to accommodate standard height 3U and 6U boards, which are equipped with standardized interface connectors and auxiliary locking mechanisms to ensure the stability and reliability of the boards during equipment operation.

[0003] However, in an in-vehicle environment, electronic devices must face long-term and continuous vibration challenges. This continuous vibration not only affects the performance and life of the device, but also poses a serious threat to the connection stability of the board. Traditional pull-out mechanisms are usually designed with an automatic rebound function, which is achieved through built-in springs. However, under long-term vibration conditions, these springs are prone to fatigue, causing the rebound function to gradually weaken or even fail completely.

[0004] When the rebound function of the auxiliary extraction mechanism fails, a series of problems will arise. First, users will encounter difficulties when inserting and removing the board, which reduces the convenience of maintenance. Second, the board that loses effective locking may produce abnormal noise during vibration, which will not only affect the user experience, but also may cover up other important equipment sounds, thus hindering the early detection of faults. More seriously, the board that has been loose for a long time may eventually fall off, causing equipment failure or even data loss. Utility Model Content

Boards that lose effective locking may produce abnormal noises during vibration, which not only affects the user experience, but also may cover up other important equipment sounds, thereby hindering the early detection of faults.

[0006] To achieve the above-mentioned purpose, the utility model provides a quick plug-in and locking mechanism for a vehicle-mounted standard plug-in box, including an auxiliary puller body, an auxiliary puller handle is installed on one side of the bottom end of the auxiliary puller body, a non-slip screw is installed on the auxiliary puller handle, the auxiliary puller body is rotatably connected to the board card through a rotating shaft, the board card is fixed in the chassis, a stop convex bump is installed on the upper end of the auxiliary puller body, and a limiting groove is arranged near the stop convex bump of the chassis. When the card board is inserted into the chassis, the stop convex bump is engaged with the limiting groove.

[0007] Preferably, a non-slipping screw rivet hole is provided on the extraction assisting handle, and the non-slipping screw connects and fixes the non-slipping screw rivet hole and the non-slipping screw mounting hole.

[0008] Preferably, a rotating shaft mounting hole is provided on one side of the board card close to the main body of the ejection aid, and the rotating shaft is rotatably connected to the rotating shaft mounting hole.

[0009] Preferably, countersunk screw mounting holes are provided at upper and lower ends of the main body of the pull-out aid, and the upper and lower ends of the rotating shaft are connected to the countersunk screw mounting holes through countersunk screws.

[0010] Preferably, one side outer wall of the stop bulge is provided with a stop bulge top, the other side outer wall of the stop bulge is provided with a stop bulge bottom, one side inner wall of the limiting groove is provided with a limiting groove bottom, and the other side inner wall of the limiting groove is provided with a limiting groove top.

[0011] Preferably, the lower side of the stop convex bump is an arc-shaped concave structure, and the upper side of the stop convex bump is a flat structure. When the auxiliary extraction handle is pulled, the upper side of the stop convex bump and the upper side of the limiting groove are in contact with each other and the board can be pulled out.

[0012] Preferably, the outer wall of the screw that does not fall out is provided with anti-slip grooves.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The unique handle design and rotatable function of the quick plug-in and locking mechanism for the vehicle-mounted standard plug-in box greatly simplifies the plug-in and pull-out process of the board, which not only improves the operating efficiency, but also makes it more convenient to replace the board in a limited space. Secondly, the non-slip screws on the handle effectively prevent the screws from accidentally falling off or losing during installation or removal, thereby reducing the complexity of maintenance and potential safety risks. More importantly, the mechanism significantly enhances the vibration resistance of the board by returning the handle to the center and tightening with non-slip screws. This design innovation directly solves the problem that traditional springs are prone to fatigue and looseness in long-term vibration environments, thereby effectively reducing abnormal noises, loose boards, and even falling off caused by vibration, and greatly improving the stability and reliability of the equipment. Overall, this quick plug-in and locking mechanism not only optimizes the board replacement process, but also significantly improves the operating performance and service life of the equipment in vibration environments such as vehicles.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a quick plug-in and locking mechanism for a vehicle-mounted standard plug-in box, such as Figure 1-Figure 7As shown, it includes an auxiliary puller body 204, an auxiliary puller handle 104 is installed on one side of the bottom end of the auxiliary puller body 204, a non-slip screw 205 is installed on the auxiliary puller handle 104, the auxiliary puller body 204 is rotatably connected with the board 201 through the rotating shaft 203, the board 201 is fixed in the chassis 2, a stop convex 1 is installed on the upper end of the auxiliary puller body 204, and the chassis 2 is provided with a limiting groove 3 near the stop convex 1. When the board 201 is inserted into the chassis 2, the stop convex 1 is engaged with the limiting groove 3. The combination of the auxiliary puller body 204 and the auxiliary puller handle 104 enables the operator to easily apply force when inserting or pulling out the board, and the design of the rotating shaft 203 ensures that the auxiliary puller can rotate flexibly, further improving the convenience of operation. The introduction of the non-slip screw 205 not only enhances the stability of the structure, but also effectively prevents the screw from loosening or falling off in a vibration environment, thereby greatly improving the safety and reliability of the equipment. At the same time, the precise engagement between the stop convex bump 1 and the limit groove 3 ensures that the board 201 can be accurately inserted into the chassis, avoiding poor contact or data transmission problems caused by improper insertion.

[0026] In this embodiment, the extraction assisting handle 104 is provided with a non-slipping screw rivet hole 103 , and the non-slipping screw 205 connects and fixes the non-slipping screw rivet hole 103 and the non-slipping screw mounting hole 207 , so as to facilitate the locking and fixation of the extraction assisting handle 104 .

[0027] Specifically, a rotating shaft installation hole 202 is provided on one side of the board 201 close to the main body 204 of the pull-out aid, and the rotating shaft 203 is rotatably connected to the rotating shaft installation hole 202 to facilitate the rotation of the main body 204 of the pull-out aid.

[0028] Furthermore, countersunk screw mounting holes 105 are provided at the upper and lower ends of the pull-out aid body 204 , and the upper and lower ends of the rotating shaft 203 are connected to the countersunk screw mounting holes 105 through countersunk screws 206 , which facilitates the installation and positioning of the pull-out aid body 204 .

[0029] Furthermore, one side outer wall of the stop bulge 1 is provided with a stop bulge upper portion 101, and the other side outer wall of the stop bulge 1 is provided with a stop bulge lower portion 102, one side inner wall of the limiting groove 3 is provided with a limiting groove lower portion 301, and the other side inner wall of the limiting groove 3 is provided with a limiting groove upper portion 302, thereby realizing the positioning of the board 201 in the chassis 2.

[0030] Furthermore, the lower surface 102 of the stop convex bump is an arc-shaped concave structure, and the upper surface 101 of the stop convex bump is a flat structure. When the auxiliary extraction handle 104 is pulled, the upper surface 101 of the stop convex bump and the upper surface 302 of the limiting groove are in contact with each other and the board 201 can be pulled out.

[0031] Furthermore, the outer wall of the non-slipping screw 205 is provided with anti-skid patterns, which provide an anti-skid effect when the non-slipping screw 205 is rotated.

[0032] When the utility model is used for the quick plug-in and locking mechanism of the vehicle-mounted standard plug-in box, when the board 201 needs to be inserted into the chassis 2, the operator first pulls the auxiliary pull-out handle 104 outward to put it in the open state. Then, the connector socket at the rear end of the board 201 is docked with the plug in the chassis. In this process, the auxiliary pull-out body 204 is flexibly rotated through the rotating shaft 203 to adapt to the insertion angle. Once the board 201 is inserted into place, the operator rotates the auxiliary pull-out handle 104, at which time the lower side 102 of the stop convex bump on the stop convex bump 1 and the lower side 301 of the limit groove on the chassis 2 are in contact with each other to ensure that the connector is inserted into place. At the same time, the auxiliary pull-out handle 104 is in contact with the front end face of the board 201, and the non-slip screw 205 is aligned with the non-slip screw mounting hole 207 on the board 201 and tightened, thereby locking the auxiliary pull-out to the front end face of the board 201, thereby enhancing the stability of the structure.

[0033] When the board 201 needs to be pulled out, the operator first loosens the screw 205 that does not come out, and then pulls the auxiliary pull handle 104 outward. During the pulling process, the stop convex bump 101 and the limit groove 302 are in contact with each other and receive force. Through this precise snap fit, the board 201 will not be offset or tilted during the pulling process, so that the board 201 can be pulled out of the chassis 2 smoothly. During the entire plugging and unplugging process, the screw 205 that does not come out and the anti-slip pattern design ensure the stability and safety of the operation, which is particularly suitable for equipment maintenance in vibration environments such as vehicles.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
