Description

Technical Field

[0001] This utility model relates to the field of nut technology, specifically a nut component with a built-in sealing test hole. Background Technology

[0002] Fasteners generally include nuts and bolts. During storage and disassembly, dust and other impurities can easily adhere to their surfaces. When nuts and bolts are screwed together, these impurities can become embedded in the structure, causing it to jam. Furthermore, during assembly, insufficient sealing, tightness, and strength of the screw connection result in poor fastening strength and stability of the nuts. Utility Model Content

[0003] The purpose of this utility model is to solve the problems that existing nuts and corresponding bolts are prone to dust and other impurities adhering to their surfaces, causing impurities to become embedded in the structure when the nut and bolt are screwed together, resulting in the structure getting stuck. Furthermore, the screw connection is not tight enough, and the screw connection strength is insufficient during assembly, resulting in poor fastening strength and stability of the nut. Therefore, this utility model provides a nut with a built-in sealing test hole.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a nut component with a built-in sealing test hole, comprising:

[0005] The nut body has an internal thread on the inner wall of the through hole in the middle, and several test holes are also provided laterally through it.

[0006] The brush is arranged at the edge of the end face of the through hole and is spaced out along the circumference of the nut body.

[0007] As a further description of the above technical solution:

[0008] The test holes are arranged at an angle to the axis of the nut body.

[0009] As a further description of the above technical solution:

[0010] The inner end of the brush extends obliquely toward the outer side of the end face of the nut body.

[0011] As a further description of the above technical solution:

[0012] The nut body has a wedge-shaped or arc-shaped transition surface at its side edge.

[0013] As a further description of the above technical solution:

[0014] The nut body has a countersunk groove on the outside of the through hole, and the outer end of the brush is positioned on the annular base plate, which is embedded in the countersunk groove.

[0015] As a further description of the above technical solution:

[0016] The annular base plate and the countersunk groove are positioned by pins.

[0017] In summary, by adopting the above technical solution, this utility model has the following advantages over the prior art:

[0018] Beneficial effects:

[0019] 1. When the nut of this utility model is assembled with the bolt, the two rotate relative to each other, causing the brush to clean the surface of the bolt. This removes dust and other impurities from the bolt. Some impurities are directly pushed away from the fastener formed by the nut and bolt by the brush, while others are guided out of the nut through the test hole. This prevents impurities from embedding in the fastener, which could lead to structural jamming, loose screw connections, or insufficient fastening strength. After assembly, airflow or other fluid media can be introduced into the fastener through the test hole, and fluid leakage can be detected at the mating surface of the fastener. This ensures the sealing and tightness of the fastener assembly, thereby guaranteeing its fastening strength.

[0020] 2. The inclined arrangement of test holes and brushes can improve the cleaning effect on the bolt surface, allowing the fasteners to be fully discharged.

[0021] 3. The brush is detachably, replaceably, and maintainably assembled on the nut part via a ring-shaped base plate, further improving the cleaning effect on the bolt. Attached Figure Description

[0029] Example 1:

[0030] Please see Figure 1-2 This utility model provides a technical solution: a nut component with a built-in sealing test hole, comprising:

[0031] The nut body 1 has an internal thread 2 on the inner wall of the through hole in the middle, and several test holes 3 are also provided laterally through it;

[0032] The brush 4 is arranged at the edge of the end face of the through hole and is spaced out along the circumference of the nut body 1.

[0033] The assembly process of a nut with a built-in sealing test hole in this embodiment includes: during the assembly of the nut and bolt, the two rotate relative to each other, causing the brush 4 to clean the bolt surface, removing dust and other impurities from the bolt. Some impurities are directly pushed away from the fastener formed by the nut and bolt by the brush 4, while others are guided out of the nut through the test hole 3, preventing impurities from embedding into the fastener, which could lead to structural jamming, loose screw connections, or insufficient fastening strength. After assembly, airflow or other fluid media are introduced into the fastener through the test hole 3, and fluid leakage is detected at the mating surface of the fastener, thereby ensuring the tightness of the fastener assembly and thus its fastening strength.

[0034] The test hole 3 is arranged at an angle to the axis of the nut body 1, which facilitates the guidance and discharge of internal impurities during the assembly of the nut.

[0035] The inner end of the brush 4 extends at an angle toward the outer side of the end face of the nut body 1, so that the brush 4 cleans the bolt surface on the outside of the nut and throws the swept-out impurities out of the fastener, reducing the probability of them falling into the nut and improving the cleanliness of the fastener surface.

[0036] A wedge-shaped or arc-shaped transition surface 5 is provided at the side edge of the nut body 1.

[0037] Example 2:

[0038] Please see Figure 1-2 Based on the above embodiment 1, preferably, the nut body 1 is provided with a countersunk groove 6 on the outside of the through hole, the outer end of the brush 4 is positioned on the annular base plate 7, and the annular base plate 7 is embedded in the countersunk groove 6.

[0039] The annular base plate 7 and the countersunk groove 6 are positioned by pins 8.

[0040] The assembly process of a nut component with a built-in sealing test hole in this embodiment includes: the brush 4 in this embodiment adopts a detachable design, which facilitates structural maintenance and replacement, thereby ensuring the cleaning effect on the bolts and the sealing and tightness of the nut component assembly. In use, the pin 8 is pulled out from the through hole of the annular base plate 7 and the groove on the surface of the countersunk groove 6. Then, the annular base plate 7 is removed from the countersunk groove 6, allowing replacement of the annular base plate 7 and the brush 4 on it. When replacing, the new annular base plate 7 is pressed back into the countersunk groove 6, and the structure is locked using the pin 8 for assembly and use.

[0041] In summary, due to the adoption of the above technical solution, the nut component with a built-in sealing test hole in this embodiment has the following advantages compared with the prior art:

[0042] 1. When the nut of this utility model is assembled with the bolt, the two rotate relative to each other, causing the brush to clean the surface of the bolt. This removes dust and other impurities from the bolt. Some impurities are directly pushed away from the fastener formed by the nut and bolt by the brush, while others are guided out of the nut through the test hole. This prevents impurities from embedding in the fastener, which could lead to structural jamming, loose screw connections, or insufficient fastening strength. After assembly, airflow or other fluid media can be introduced into the fastener through the test hole, and fluid leakage can be detected at the mating surface of the fastener. This ensures the sealing and tightness of the fastener assembly, thereby guaranteeing its fastening strength.

[0043] 2. The inclined arrangement of test holes and brushes can improve the cleaning effect on the bolt surface, allowing the fasteners to be fully discharged.

[0044] 3. The brush is detachably, replaceably, and maintainably assembled on the nut part via a ring-shaped base plate, further improving the cleaning effect on the bolt.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
