[0031] Figures 1 to 8 The mounting fastening kit in some embodiments of the present invention is shown. The mounting fastening kit can be used for panel and wall installation, and includes a mounting fastening assembly and an active member 4. In some embodiments, the mounting fastening assembly and the active member 4 can be connected together in a detachable manner such as a threaded connection. The mounting fastening assembly includes a hollow sleeve 1, a driven member 2, and a pressure ring 3.

[0032] See also Figure 1 to Figure 2 , Figure 1 This is a schematic diagram of the structure for installing the fastening components. Figure 2 An exploded view of the installation fastening assembly is shown. The side wall of the hollow sleeve 1 is provided with a movable groove 11 that runs through the thickness direction thereof. The extending direction of the movable groove 11 is consistent with the length direction of the hollow sleeve 1. The follower 2 and the pressure ring 3 are both arranged in the hollow sleeve 1, and the pressure ring 3 is arranged along the movement direction of the follower 2. The central axis of the hollow sleeve 1, the follower 2 and the pressure ring 3 coincide, and the active member 4 axially runs through the hollow sleeve 1, the pressure ring 3 and the follower 2. The outer diameter of the active member 4 is smaller than the inner diameter of the pressure ring 3, and the inner diameter of the pressure ring 3 is larger than the inner diameter of the follower 2. The outer diameter of the active member 4 is adapted to the inner diameter of the follower 2.

[0033] The active member 4 has an external thread, the driven member 2 has an internal thread, the active member 4 and the driven member 2 are threadedly matched, the active member 4 rotates to drive the driven member 2 to perform linear motion along the axis direction of the active member 4, so that the driven member 2 presses against the pressing ring 3. In some embodiments, the driven member 2 can be a nut, and the active member 4 can be a screw, a bolt or a stud.

[0034] See also Figure 3 to Figure 4 , Figure 3 A top view of the installation fastening assembly. Figure 4 In the bottom view of the installation fastening assembly, the outer contour of the cross section of the follower 2 is a closed shape formed by connecting a circular arc and parallel straight lines end to end, and the inner contour of the cross section of the hollow sleeve 1 is consistent with the shape of the outer contour of the cross section of the follower 2, so that the follower 2 cannot rotate in the hollow sleeve 1, but can only move along the active member 4. In other embodiments, the outer contour of the cross section of the follower 2 can also be a polygon, such as a quadrilateral, hexagon, etc. The outer contour of the cross section of the follower 2 is consistent with the shape and size of the outer contour of the pressing surface of the pressure ring 3 and the follower 2, so that the pressing surface area of ​​the follower 2 and the pressure ring 3 is maximized, so that the follower 2 can act on the pressure ring 3 more evenly.

[0035] In some embodiments, the number of the pressing ring 3 is at least one, for example, it can be one, two, three or any number, and at least one pressing ring 3 is sequentially stacked in the hollow sleeve 1. At least two side wings 31 are provided on the pressing ring 3, and at least two side wings 31 extend outward from the edge of the pressing ring 3 away from the follower 2. When the number of the side wings 31 is two, one side wing 31 is located on one side of the length direction of the hollow sleeve 1, and the other side wing 31 is located on the other side of the length direction of the hollow sleeve 1. Preferably, the number of the side wings 31 is an even number, and the side wings 31 are symmetrically arranged in pairs on both sides of the length direction of the hollow sleeve 1. Further, the side wings 31 pass through the movable groove 11 of the hollow sleeve 1, and move in the movable groove 11 along the length direction of the hollow sleeve 1, and finally the side wings 31 abut against the installation panel 5 or the wall 7. The width of the movable groove 11 is adapted to the width of the side wings 31, and the number of the movable grooves 11 is equal to the number of the side wings 31 of a single pressing ring 3.

[0036] A convex ring 12 is provided on the side wall of the end of the hollow sleeve 1 away from the follower 2, and the convex ring 12 abuts against the outer surface of the mounting panel 5 or the wall 7 to prevent the hollow sleeve 1 from being embedded in the mounting panel 5 or the wall 7 as a whole. At least one claw 13 extending inward is provided at one end of the hollow sleeve 1 close to the follower 2 to prevent the follower 2 from falling out of the hollow sleeve 1. In some embodiments, the number of the claws 13 can be at least two, three or any number, and the claws 13 are arranged at intervals along the circumference of the port at one end of the hollow sleeve 1.

[0037] For panel installation scenarios, for example, installing a device panel 6 on a mounting panel 5, the device is an electronic device or a communication device, and Figures 5 and 6 , Figure 5 This is a schematic diagram of the initial state structure of the installation fastening kit. Figure 6The figure is a schematic diagram of the locking state structure of the installation fastening kit. When performing panel installation, firstly, holes are punched on the installation panel 5 and the device panel 6 respectively, and the installation fastening kit enters from the outside of the hole of the installation panel 5, and the convex ring 12 of the hollow sleeve 1 abuts against the outer surface of the installation panel 5, and the device panel 6 is placed on the outside of the installation fastening kit, and the active member 4 enters the hollow sleeve 1 from the outside of the hole of the device panel 6 and penetrates the pressure ring 3 and the driven member 2. At this time, the installation fastening kit is in the initial state.

[0038] The active member 4 rotates to drive the driven member 2 to make a linear motion along the axis direction of the active member 4 toward the installation panel 5. The driven member 2 presses the pressing ring 3 to drive the side wings 31 to expand outward relative to the pressing ring 3, so that the pressing ring 3 is deformed and becomes a gasket. The inner side of the side wings 31 abuts against the inner surface of the installation panel 5. At this time, the installation fastening kit is in a locked state. Therefore, the equipment panel 6 can be installed on the installation panel 5 through the installation fastening kit, and the installation fastening kit can be applied to installation panels 5 of different thicknesses. It can be understood that the length of the hollow sleeve 1 and the movable groove 11 can be selected and set according to the thickness of the installation panel 5.

[0039] For wall installation scenarios, for example, the device bracket 8 is installed on the wall 7, and the device is an electronic device or a communication device. Figures 7 and 8 , Figure 7 A schematic diagram of the structure for installing the fastening assembly for wall installation. Figure 8 The schematic diagram of the structure of the installation fastening kit for wall installation is shown below. First, holes are drilled on the wall 7 and the equipment bracket 8. The diameter of the wall hole 71 matches the outer diameter of the hollow sleeve 1. The installation fastening assembly is placed in the wall hole 71, and the convex ring 12 of the hollow sleeve 1 abuts against the outer surface of the wall 7. The end of the side wing 31 of the pressure ring 3 abuts against the inner wall of the wall hole 71. The equipment bracket 8 is placed on the outside of the installation fastening assembly. The active member 4 enters the hollow sleeve 1 from the outside of the hole of the equipment bracket 8 and passes through the pressure ring 3 and the driven member 2. The head of the active member 4 abuts against the outside of the equipment bracket 8.

[0040] For the installation and fastening kit for wall installation, the number of the pressing rings 3 can be multiple, for example, three. It can be understood that the number of the pressing rings 3 can be selected and set according to actual needs to ensure the fastening effect of the installation and fastening kit. The end of the side wing 31 of the pressing ring 3 is provided with a tooth portion 32, which is conducive to strengthening the friction force of the end of the side wing 31 on the wall 7. The active member 4 rotates to drive the driven member 2 to make a linear motion along the axial direction of the active member 4 toward the equipment bracket 8. The driven member 2 presses the pressing ring 3 to generate external tension, so that the side wing 31 generates an outward force on the inner wall of the wall hole 71, so that multiple pressing rings 3 can be clamped on the inner wall of the wall hole 71. In this way, the equipment bracket 8 can be installed on the wall 7 by installing the fastening kit.

[0041] The installation and fastening kit of the present invention includes a hollow sleeve, a driven part, a pressure ring and an active part. The active part drives the driven part to act on the pressure ring, so that the pressure ring is fixed to the panel or wall, realizing tapping-free installation, and only requires drilling. It is suitable for scenes where brittle materials cannot be tapped for installation, and is compatible with panel installation and wall installation scenes of various thicknesses. The installation and fastening kit has a simple structure and is easy to implement, with low production cost and high reliability, and can adapt to repeated disassembly and assembly. Applicable objects of the installation and fastening kit include equipment, boxes, and boxes in the field of electronic equipment and communication equipment that need to be installed on panels and walls.

[0042] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the present invention.
