Description

Technical Field

[0001] This utility model is a sealing spring nut assembly, belonging to the field of spring nut technology. Background Technology

[0002] A spring nut is a type of nut with anti-loosening fastening function. To improve the sealing performance of a spring nut, a sealing cover is usually installed on the outside of the spring nut to seal the fasteners and connectors. When installing springs with different spring coefficients, different spring nuts need to be used.

[0003] Chinese patent CN222436799U proposes a sealing spring-nut assembly. Through a positioning snap-fit ​​installation structure, it can realize the installation and fixation between the spring and the nut block, and also facilitate the quick disassembly of the spring and the nut block, so as to facilitate the replacement of springs with other specifications and elastic coefficients. However, the installation and disassembly of the multiple sets of micro screws in this design are relatively inconvenient, and its quick-release function still has room for further improvement. There is an urgent need for a sealing spring-nut assembly to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a sealing spring nut assembly to solve the problems mentioned in the background. This utility model has a reasonable structure. By rotating the rotating ring, the adjusting block is moved, which in turn moves the limiting block under the action of the adjusting groove and releases it from the limiting groove, so as to facilitate the quick disassembly and installation of the spring fixing seat. It is simple and convenient to use and highly practical.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a sealing spring nut assembly, comprising a base, a storage cavity, a limiting block, an adjusting groove, a compression spring fixing seat, a spring, a rotating ring, a sealing top cover, and an adjusting block. The base has a storage cavity inside, a limiting block inside, an adjusting groove inside the limiting block, a spring fixing seat on the lower end face of the base, a compression spring on the lower end face of the spring fixing seat, a rotating ring rotatably mounted on the outer side of the base, a sealing top cover on the upper end face of the base, and an adjusting block inside the base.

[0006] Furthermore, the base has a sliding groove inside, which is connected to the inside of the storage cavity. The adjusting block slides tightly along the inner wall of the sliding groove, and the adjusting block and the adjusting groove are engaged with each other.

[0007] Furthermore, the limiting block slides tightly along the inner wall of the receiving cavity, the adjusting groove has a guide arc surface at one end relatively close to the sliding groove, and the outer side of the spring fixing seat has a limiting slot, with the limiting block and the limiting slot engaging with each other.

[0008] Furthermore, a limiting sleeve is provided inside the storage cavity, with both ends of the limiting sleeve connected to the inner wall of the storage cavity and the surface of the limiting block, respectively, and a reset spring is sleeved on the outer side of the limiting sleeve.

[0009] Furthermore, a connecting block is provided on the lower end face of the rotating ring, and the rotating ring is fixedly connected to the adjusting block through the connecting block. Anti-slip texture is provided on the outer surface of the rotating ring.

[0010] Furthermore, a rotating groove is provided on the outer side of the base, and a rotating block is provided on the inner side of the rotating ring. The rotating ring is rotatably connected to the base through the rotating block and the rotating groove.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a sealing spring nut assembly. Because it adds a rotating ring, a connecting block, an adjusting block, a limiting block, and an adjusting groove, when the spring fixing seat needs to be disassembled, the user rotates the rotating ring. The rotating ring drives the adjusting block to slide along the inner wall of the sliding groove through the connecting block, and then engages with the limiting block along the adjusting groove. During the engagement process, due to the inclined design of the adjusting groove, the limiting block is retracted into the receiving cavity, and the mutual engagement between the limiting block and the limiting groove is released, so that the spring fixing seat can be easily removed. This allows for quick replacement of compression springs with different elastic limits according to actual usage. Attached Figure Description

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a sealing spring nut assembly, including a base 1, a storage cavity 2, a limiting block 3, an adjusting groove 4, a compression spring 6 fixing seat 5, a spring, a rotating ring 7, a sealing top cover 8, and an adjusting block 9. The base 1 has a storage cavity 2 inside, a limiting block 3 inside, an adjusting groove 4 inside the limiting block 3, a spring fixing seat 5 on the lower end face of the base 1, a compression spring 6 on the lower end face of the spring fixing seat 5, a rotating ring 7 rotatably mounted on the outer side of the base 1, a sealing top cover 8 on the upper end face of the base 1, and an adjusting block 9 inside the base 1. This design solves the problem of inconvenient installation and disassembly of the original sealing spring nut assembly.

[0021] As the first embodiment of this utility model: a sliding groove 11 is provided inside the base 1, and the sliding groove 11 is interconnected with the interior of the storage cavity 2. The adjusting block 9 slides tightly along the inner wall of the sliding groove 11, and the adjusting block 9 and the adjusting groove 4 are engaged with each other. The movement of the adjusting block 9 can drive the movement of the limiting block 3 through the adjusting groove 4. The limiting block 3 slides tightly along the inner wall of the storage cavity 2. A guide arc surface 41 is provided inside the adjusting groove 4 at one end relatively close to the sliding groove 11. A limiting slot 51 is provided on the outer side of the spring fixing seat 5, and the limiting block 3 and the limiting slot 51 are engaged with each other. The storage cavity 2 provides the necessary space for the movement of the limiting block 3. The design of the limiting block 3 and the limiting slot 51 can fix the connection between the base 1 and the spring fixing seat 5. The storage cavity 2 is provided with a limiting arc surface 41. The limiting sleeve 21 has its two ends connected to the inner wall of the receiving cavity 2 and the surface of the limiting block 3, respectively. A return spring 22 is fitted on the outer side of the limiting sleeve 21. The limiting sleeve 21 makes the movement of the limiting block 3 more stable, and the return spring 22 can help the limiting block 3 to return to its original position. A connecting block 91 is provided on the lower end face of the rotating ring 7. The rotating ring 7 is fixedly connected to the adjusting block 9 through the connecting block 91. The outer side of the rotating ring 7 is provided with anti-slip texture 71. The rotating ring 7 can drive the adjusting block 9 to move together through the connecting block 91. A rotating groove 12 is opened on the outer side of the base 1. A rotating block 72 is provided on the inner side of the rotating ring 7. The rotating ring 7 is rotatably connected to the base 1 through the rotating block 72 and the rotating groove 12. This design allows the rotating ring 7 to rotate independently of the base 1.

[0022] As a second embodiment of this utility model: When the user needs to install the compression spring 6 and the spring fixing seat 5, the spring fixing seat 5 is inserted into the lower end of the base 1 from the bottom, so that the position of the limiting slot 51 corresponds to the position of the limiting block 3. During the insertion process, the spring fixing seat 5 exerts a certain amount of pressure on the limiting block 3, causing the limiting block 3 to retract into the receiving cavity 2. When the limiting block 3 and the limiting slot 51 are at the same horizontal height, the reset spring 22 drives the limiting block 3 to reset, and the limiting block 3 and the limiting slot 51 engage with each other, thereby securing the device. The position between the fixed base 1 and the spring fixing seat 5 is determined. When the spring fixing seat 5 needs to be disassembled, the user rotates the rotating ring 7. The rotating ring 7 drives the adjusting block 9 to slide along the inner wall of the sliding groove 11 through the connecting block 91, and then inserts into the limiting block 3 along the adjusting groove 4. During the insertion process, due to the inclined design of the adjusting groove 4, the limiting block 3 is retracted into the storage cavity 2, and the mutual locking state between the limiting block 3 and the limiting groove 51 is released, so that the spring fixing seat 5 can be removed smoothly, thereby allowing for quick replacement of the compression spring 6 with different elastic limits according to the actual use.
