Description

Technical Field

[0001] This utility model relates to the field of nut technology, specifically to a spring nut with a self-locking structure. Background Technology

[0002] In the fastener industry, leaf spring nuts are a common type of nut used in the automotive manufacturing sector, found in various automotive components. Leaf spring nuts utilize a spring-like design to maintain a tight grip in vibrating environments, preventing loosening and thus increasing equipment safety and stability, reducing equipment failures and maintenance costs. Traditionally, leaf spring nuts are installed by directly drilling mounting holes at corresponding positions on the edge of the guard plate, relying on the clamping force of the spring to fix the nut to the mounting holes.

[0003] For example, Chinese patent CN221569157U discloses a spring-nut assembly, including an upper spring with a nut on it, and a lower spring below it. Fixing blocks are installed on the inner walls of the upper and lower springs, in four sets. These four sets of fixing blocks are symmetrically installed on the inner walls of the upper and lower springs. Threaded holes are provided on both the upper and lower springs. A fixing groove is provided on one side of the outer wall of the upper spring, in two sets, symmetrically located on the upper spring. By installing fixing blocks on the inner walls of the upper and lower springs, and by ensuring the fixing blocks are flexible and non-slip, the overall anti-slip effect is enhanced when the spring is fixed. The fixing groove on the upper spring facilitates the insertion of other springs onto one side of it, allowing for expansion of spring installation according to different installation positions.

[0004] However, this technology has the following problems: the spring nut and screw of this technology do not have a self-locking function, and it is impossible to avoid the phenomenon of loosening after the spring nut has been used for a long time.

[0005] Based on this, the present invention designs a spring nut with a self-locking structure to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a spring nut with a self-locking structure.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A spring nut with a self-locking structure includes an upper spring and a lower spring, the right sides of which are connected by a connecting piece; the upper spring has an upper hole in the middle and the lower spring has a lower hole in the middle, and the nut is fixedly connected to the upper spring;

[0009] The nut has a slot at the top, and a rubber gasket is fixedly installed at the bottom of the slot. The lower ends of the nut and the lower spring are both connected to a screw self-locking structure. The upper end of the nut is fixedly installed with a marking component for determining the screw installation position.

[0010] Furthermore, the upper hole and the lower hole are located on the same center line.

[0011] Furthermore, the lower spring has a slot at its front end and a block fixedly installed at its rear end.

[0012] Furthermore, there are two slots located on the left and right sides of the front end of the lower spring, and two blocks located on the left and right sides of the rear end of the lower spring.

[0013] Furthermore, the card slot engages with the card block.

[0014] Furthermore, the screw self-locking structure includes a rigid washer, an annular plate, and a barb. The rigid washer is fixedly installed at the bottom of the nut, the annular plate is fixedly installed at the bottom of the lower spring plate and communicates with the lower hole, and the barb is fixedly installed at the bottom of the annular plate.

[0015] Furthermore, the lower end of the barb bends inward.

[0016] Furthermore, the marking assembly includes a fixing plate, a through groove, a spring, a locking block, and an inclined surface. The fixing plate is fixedly installed on the upper end of the nut. The through groove is opened on the inner wall of the fixing plate. The spring is located inside the through groove, and the right side of the inside of the through groove is fixedly connected to one end of the spring. The other end of the spring is fixedly connected to the locking block. Two inclined surfaces are provided and are respectively opened at the upper and lower ends of the locking block.

[0017] Compared with the prior art, the advantages of this utility model are as follows: When in use, this utility model combines the device with a screw, and the screw self-locking structure provides secondary limiting and locking for the screw. After the screw is installed, the marking component confirms whether the screw is installed in place, ensuring the tightness of the screw installation. This utility model achieves multiple locking of the screw through rigid washers and barbs, preventing the screw from loosening during long-term use. It also uses locking blocks to determine the installation position of the screw, ensuring the tightness of the screw installation. Furthermore, this utility model can use the limiting and locking function of slots and blocks to lock multiple spring nuts together for fastening. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0031] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8 It includes an upper spring 1 and a lower spring 2, with the right sides of the upper spring 1 and the lower spring 2 connected by a connecting piece; the upper spring 1 has an upper hole 3 in the middle, and the lower spring 2 has a lower hole 4 in the middle, and the nut 5 is fixedly connected to the upper spring 1.

[0032] The nut 5 has a slot 6 at its top, and a rubber gasket 7 is fixedly installed at the bottom of the slot 6. The nut 5 and the lower spring 2 are both connected to a screw self-locking structure 8. The upper end of the nut 5 is fixedly installed with a marking component 9 for determining the screw installation position.

[0033] When in use, this utility model combines the device with a screw. The screw self-locking structure 8 provides secondary limiting and locking for the screw. The screw is marked by the marking component 9 to indicate that it is installed in place. This utility model achieves the locking function of the spring nut on the screw through secondary locking, preventing the spring nut from loosening under long-term use and affecting the product's performance.

[0034] Example 2: In some embodiments, such as Figures 1-8 As shown, in a preferred embodiment of this utility model, the upper hole 3 and the lower hole 4 are located on the same center line.

[0035] The lower spring 2 has a slot 10 at its front end and a block 11 fixedly installed at its rear end.

[0036] Two slots 10 are provided and are located on the left and right sides of the front end of the lower spring 2, respectively. Two blocks 11 are provided and are located on the left and right sides of the rear end of the lower spring 2, respectively.

[0037] The card slot 10 is engaged with the card block 11.

[0038] The screw self-locking structure 8 includes a rigid washer 81, an annular piece 82, and a barb 83. The rigid washer 81 is fixedly installed on the bottom of the nut 5, the annular piece 82 is fixedly installed on the bottom of the lower spring 2 and communicates with the lower hole 4, and the barb 83 is fixedly installed on the bottom of the annular piece 82.

[0039] The lower end of the barb 83 bends inward.

[0040] The marking component 9 includes a fixing piece 91, a through groove 92, a spring 93, a locking block 94, and an inclined surface 95. The fixing piece 91 is fixedly installed on the upper end of the nut 5. The through groove 92 is opened on the inner wall of the fixing piece 91. The spring 93 is located inside the through groove 92, and the right side of the inside of the through groove 92 is fixedly connected to one end of the spring 93. The other end of the spring 93 is fixedly connected to the locking block 94. There are two inclined surfaces 95, which are respectively opened at the upper and lower ends of the locking block 94.

[0041] When this utility model is in use, when the screw and nut 5 are engaged, the rigid washer 81 is pressed downward, and the inner structure of the rigid washer 81 is compressed to deform downward, thereby limiting and locking the screw for the first time, so that the screw can only move downward. When the screw moves to the position of the barb 83, the lower end of the barb 83 bends inward and forms a limiting lock with the thread on the screw, thereby locking the screw for the second time, so that the screw can only move downward.

[0042] When the top of the screw enters the fixing plate 91, under the action of the upper inclined surface 95, the top of the screw presses against the locking block 94. The locking block 94 moves inward under the force of the spring 93, so that the top of the screw enters the slot 6 and fits against the rubber pad 7. The rubber pad 7 is used to prevent the top of the screw from rotating.

[0043] After the top of the screw enters the slot 6, it disengages from the locking block 94. The locking block 94 moves outward under the action of the spring 93 and engages above the top of the screw, thereby marking the top of the screw to indicate that the screw has been installed in place.

[0044] When the screw is removed, it moves upward and presses against the lower inclined surface 95, causing the locking block 94 to move inward under the force of the spring 93, thereby disengaging the screw. After the screw is disengaged, the locking block 94 moves outward to reset under the action of the spring 93.

[0045] This invention achieves multiple locking of screws through rigid washers 81 and barbs 83, preventing screws from loosening during long-term use. It also uses locking blocks 94 to determine the installation position of screws, ensuring the tightness of screw installation. Furthermore, this invention can use the limiting and locking functions of slots 10 and blocks 11 to lock multiple spring nuts together for fastening.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this 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 of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
