[0002] A shielding cover is a tool used to shield electronic signals. Its function is to shield the influence of external electromagnetic waves on internal circuits and the outward radiation of electromagnetic waves generated internally.

[0003] At present, there are three main ways to install the shielding cover and the connector: bonding, welding, and screw connection. All of the above methods will cause inconvenience in the installation and subsequent disassembly and maintenance process, and the operation is relatively cumbersome. The patent document with the prior art publication number CN218451089U provides a power distribution shielding cover with a fixed structure. When the force applied to the slider is loosened, the spring will restore its elasticity and push out the column, so that the end of the column fits against the outer wall of the electronic equipment body, forming a fast fixed installation effect for the shielding cover, and also facilitating the rapid disassembly of the shielding cover.

[0004] The device relies on the elastic force of the spring to drive the abutment column to abut against the electronic device body, which has poor stability. The vibration of the device during use may cause displacement or even fall off. Therefore, a fixing structure of the shielding cover is urgently needed to solve the above problem. Utility Model Content

[0005] In view of the above-mentioned problems that the prior art relies on the elastic force of the spring to drive the abutting column to abut against the electronic device body, has poor stability, and the vibration of the device during use may cause displacement or even fall off, the present utility model is proposed.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a fixing structure of a shielding cover, comprising a shielding cover body, and also comprising connecting plates fixedly connected to two symmetrical sides of the shielding cover body, both sides of the connecting plate are fixedly connected with fixing mechanisms, and a locking assembly is connected between the two fixing mechanisms;

[0008] The fixing mechanism comprises a fixing cylinder, a pull rod is slidably connected in the fixing cylinder, a conical block is fixedly connected to one end of the pull rod, and a rubber ring is sleeved on the pull rod;

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] Example 1

[0026] Reference Figure 1-3 , which is the first embodiment of the utility model, provides a fixing structure of a shielding cover, the fixing structure of the shielding cover includes a shielding cover body 1, and also includes a connecting plate 2 fixedly connected to the shielding cover body 1 on both sides symmetrically, and fixing mechanisms 3 are fixedly connected on both sides of the connecting plate 2, and a locking assembly 4 is connected between the two fixing mechanisms 3.

[0027] In the above technical solution, after the connecting plates 2 are installed on both sides of the shielding cover main body 1, when the shielding cover main body 1 is connected to the connecting piece, the fixing mechanism 3 passes through the mounting hole of the connecting piece, and then the locking assembly 4 is moved, so that the fixing mechanism 3 can limit the connecting piece, so that the shielding cover main body 1 is fixed on the connecting piece.

[0028] The fixing mechanism 3 comprises a fixing cylinder 301 , in which a pull rod 302 is slidably connected, one end of the pull rod 302 is fixedly connected to a cone block 303 , and a rubber ring 304 is sleeved on the pull rod 302 .

[0029] In the above technical solution, the diameters of the fixing tube 301, the conical block 303 and the rubber ring 304 are all smaller than the diameter of the mounting hole on the connector. The conical block 303 can pass through the mounting hole of the connector and drive the rubber ring 304 to be arranged on the other side of the connector. When the pull rod 302 is pulled, the conical block 303 cooperates with the end of the fixing tube 301 to vertically compress the rubber ring 304 to form a horizontal extension, thereby limiting the mounting hole and limiting the shielding cover body 1 on the connector.

[0030] It is understandable that the distance between the two fixing tubes 301 on the connecting plate 2 is adjusted according to the distance between the mounting holes on the connecting piece, so that when the shielding cover body 1 contacts the connecting piece, the fixing tube 301 can drive the conical block 303 and the rubber ring 304 to accurately pass through the mounting hole.

[0031] The locking assembly 4 includes a cross bar 1 401 connected to the pull rod 302, a cross bar 2 402 is fixedly connected to the cross bar 1 401, the cross bar 2 402 is slidably matched with the fixed cylinder 301, and a brake rod 403 is slidably connected inside the cross bar 2 402, and the brake rod 403 is snap-fitted with the fixed cylinder 301.

[0032] In the above technical solution, when the cross bar 402 is moved, the cross bar 1 401 drives the pull rod 302 to move synchronously. When the brake rod 403 is moved to engage with the fixed tube 301, the movement of the cross bar 2 402 can be braked, so that the pull rod 302 cannot slide, thereby keeping the rubber ring 304 stable.

[0033] A spring 305 is sleeved on the pull rod 302 , and two ends of the spring 305 are respectively connected and fixed to the pull rod 302 and the fixing tube 301 .

[0034] In the above technical solution, when the pull rod 302 moves and drives the rubber ring 304 to deform, the spring 305 is compressed and stored at the same time, so that when it is necessary to cancel the limit of the rubber ring 304 on the connecting piece, the spring 305 is reset to drive the pull rod 302 to move in the opposite direction, so that the deformation of the rubber ring 304 is restored.

[0035] A plurality of arc-shaped strips 306 are fixedly arranged at equal intervals on the outside of the fixing tube 301 , and a limiting groove 404 matching with the arc-shaped strip 306 is formed at one end of the brake rod 403 .

[0036] In the above technical solution, the brake rod 403 can slide straightly in the second cross bar 402. When the limiting groove 404 is engaged with the arc strip 306, the sliding of the second cross bar 402 can be restricted, so that the second cross bar 402 and the fixed cylinder 301 are fixedly connected.

[0037] Among them, refer to Figure 2 and Figure 3 A groove matching the fixed cylinder 301 is formed at the end of the second cross bar 402 , and the second cross bar 402 slides on the fixed cylinder 301 through the groove, so that the second cross bar 402 can slide straightly between the two fixed cylinders 301 .

[0038] A sleeve 405 is rotatably connected to the second crossbar 402 , and both ends of the sleeve 405 are provided with internal threads. A slider 406 is fixedly connected to one end of the brake rod 403 , and the slider 406 passes through the second crossbar 402 and is provided with external threads.

[0039] In the above technical solution, the slider 406 is arranged on the inner side of the sleeve 405, and the internal thread and the external thread are threadedly matched. When the sleeve 405 is rotated, the internal thread and the external thread cooperate to drive the slider 406 to slide, thereby driving the brake rod 403 to move in the cross bar 402, thereby realizing the clamping or cancellation of the limit groove 404 and the arc strip 306.

[0040] Among them, refer to Figure 3 The surface of the sleeve 405 is provided with a plurality of anti-slip grooves, so that a person can drive the sleeve 405 to rotate on the cross bar 402 by hand.

[0041] During use, the shielding cover body 1 is fitted with the shielding part of the connecting piece, so that the fixing tube 301 drives the conical block 303 and the rubber ring 304 to pass through the mounting hole on the connecting piece, and then the personnel drives the cross bar 402 to pull toward the top side of the shielding cover body 1 by hand, so that the cross bar 401 drives the pull rod 302 to move, and the conical block 303 cooperates with one end of the fixing tube 301 to make the rubber ring 304 squeezed vertically and stretched horizontally, so that the rubber ring 304 is larger than the size of the mounting hole after deformation, so that it cannot be separated from the mounting hole, thereby limiting the shielding cover body 1 on the connecting piece.

[0042] Then the personnel manually drives the sleeve 405 to rotate, and the internal thread and the external thread cooperate to drive the slider 406 to slide in the second cross bar 402. When the two sliders 406 move away from each other, the slider 406 can drive the limiting groove 404 at the end of the rotating rod 403 to engage with the arc strip 306 on the outer wall of the fixed cylinder 301, thereby braking the sliding of the second cross bar 402, so that the rubber ring 304 remains stable after deformation.

[0043] Example 2

[0044] Reference Figure 4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that two limiting sleeves 407 are slidably connected to the second crossbar 402 , and the limiting sleeves 407 are in abutment with the sleeve 405 .

[0045] In the above technical solution, the limiting sleeve 407 slides straight along the axial direction of the second cross bar 402, and the limiting sleeve 407 is fixed with multiple protrusions in a circular shape with equal intervals on the side facing the sleeve 405. At the same time, the end of the sleeve 405 is provided with a slot that is compatible with the protrusion. When the sliding limiting sleeve 407 abuts against the sleeve 405, the protrusion and the slot are plugged into each other, which can limit the rotation of the sleeve 405, further improving the stability of the brake rod 403 when it abuts against the fixed cylinder 301, and avoiding loosening when subjected to external force.

[0046] The remaining structures are the same as those of Example 1.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
