Description

Technical Field

[0001] The utility model relates to the field of electrical engineering and electrical technology, in particular to a bellows double-locking waterproof joint. Background Art

[0002] The bellows waterproof joint is a special pipe connection component, which can not only realize the connection of pipes, but also effectively prevent water and other liquids from penetrating into the inside of the pipes, thereby protecting the wires and cables in the pipelines from the influence of the external environment. It not only provides excellent waterproof protection, but also has multiple advantages such as high temperature resistance, corrosion resistance, and easy maintenance. It is an important component to ensure the safe and stable operation of the electrical system. Here, the utility model proposes a bellows double-locking waterproof joint.

[0003] According to the search, the Chinese patent document, announcement number: CN214146904U, discloses a waterproof bellows joint, which is provided with locking ring structures at both ends of the bellows joint body, and the sealing ring is precisely fitted to the outer wall of the bellows while the locking ring structure is locked, thereby forming a locking and sealing effect, thereby achieving a waterproof effect. However, in actual use, since the locking sleeve is threadedly connected to the bellows joint body, and the locking ring cover is threadedly connected to the locking sleeve, not only the overall sealing effect is reduced, but also the device is not provided with a corresponding limit assembly, so after long-term use, it may be disengaged and the teeth may slip, which reduces the overall service life of the device. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a bellows double-locking waterproof joint, which has the advantages of easy installation, good sealing and waterproofing, anti-aging, high temperature resistance, and improved overall service life, thereby solving the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a corrugated pipe double-locking waterproof joint, comprising a joint body, the top surface of the joint body is provided with a first threaded tube, the outer side surface of the first threaded tube is threadedly connected with a locking cap, the bottom surface of the joint body is provided with a second threaded tube, the outer side surface of the second threaded tube is threadedly connected with a locking sleeve, a hexagonal limit ring and a fixing nut.

[0008] Preferably, a plurality of separation grooves are provided on the top of the first threaded tube, and a locking slope is provided inside the locking cap.

[0009] Through the above technical solution, parts such as the bellows are inserted into the interior of the first threaded tube and the locking cap is tightened. When the locking bevel of the locking cap moves downward to the top of the first threaded tube, the top of the first threaded tube will be subjected to the pressure of the locking bevel and continue to shift inward, thereby effectively locking and fixing parts such as the bellows, thereby improving the overall stability of the device.

[0010] Preferably, a plurality of grooves are formed on the outer side surface of the second threaded tube, and locking blocks are disposed inside the plurality of grooves.

[0011] Through the above technical solution, parts such as the bellows are inserted into the interior of the second threaded tube and the locking sleeve is tightened. When the locking sleeve moves upward to the position of multiple locking blocks, the inner side surface of the locking sleeve contacts the inclined surfaces of the multiple locking blocks and can squeeze them inward. The multiple locking blocks are offset inward and can effectively lock and fix parts such as the bellows, thereby improving the overall stability of the device.

[0012] Preferably, the outer side surface of the locking cap is provided with a plurality of anti-slip blocks, and the outer side surface of the locking sleeve is provided with a plurality of anti-slip grooves.

[0013] Through the above technical solution, when the operator manually rotates the locking cap or locking sleeve, multiple anti-slip blocks and anti-slip grooves can effectively increase the contact friction and prevent slipping, making it convenient for the operator to tighten or remove and improving the overall practicality of the device.

[0014] Preferably, sealing rings are provided on both the top surface and the bottom surface of the joint body.

[0015] Through the above technical solution, the two sealing rings can form an effective seal with the locking cap, locking sleeve, bellows and other parts, ensuring the sealing and reliability of the device connection. At the same time, the sealing rings can also withstand a certain pressure to help disperse and balance the pressure in the device pipeline, thereby protecting it from damage and improving overall safety.

[0016] Preferably, the outer side surfaces of the joint body and the fixing nut are both provided with hexagonal wrench slots.

[0017] Through the above technical solution, by inserting a wrench or other tools into the hexagonal wrench slot, the connector body can be conveniently connected to other parts, or the hexagonal limit ring and the fixing nut can be installed on the outer side of the second threaded tube. The hexagonal limit ring and the fixing nut can effectively prevent the locking sleeve from being disengaged and slipping, thereby improving the overall convenience and service life of the device.

[0018] Compared with the prior art, the utility model provides a bellows double-locking waterproof joint, which has the following beneficial effects:

[0019] When the locking sleeve is moved upward to the position of the plurality of locking blocks, the inner side surface of the locking sleeve contacts the inclined surfaces of the plurality of locking blocks and can squeeze them inwardly, and the plurality of locking blocks are deflected inwardly, so that the bellows and other parts can be effectively locked and fixed, thereby improving the overall stability of the device; at the same time, the plurality of anti-sliding blocks and the anti-skid grooves can effectively increase the friction of their contact and prevent slipping, which is convenient for operators to tighten or remove and improves the overall practicality of the device.

[0020] 2. The utility model can form an effective seal with the locking cap, locking sleeve, bellows and other parts through two sealing rings, ensuring the sealing and reliability of the device connection. At the same time, the sealing ring can withstand a certain pressure to help disperse and balance the pressure in the device pipeline, thereby protecting it from damage and improving the overall safety; by inserting tools such as wrenches into the hexagonal wrench slot, the joint body can be conveniently connected to other parts, or the hexagonal limit ring and the fixing nut can be installed on the outer side of the second threaded tube. The hexagonal limit ring and the fixing nut can effectively prevent the locking sleeve from being disengaged and slipping; in addition, all parts of the device are made of PA66 new material, which is resistant to aging, high and low temperature resistance, and has a small shrinkage ratio, thereby improving the overall practicality and service life of the device.
