Description

Technical Field

[0001] The utility model relates to the technical field of threaded joints, in particular to an adjustable threaded pipe joint structure. Background Art

[0002] A threaded joint refers to a pipe connector with threads, which is the most common type of pipe fitting in industry and daily life. The threaded joint makes the connection of pipes simpler, and disassembly and replacement are also easier, greatly saving the cost of pipe connection. When laying pipes, due to reasons such as cutting and measurement, when the laying is completed, the connector cannot be connected to both ends of the water pipe. Therefore, it is necessary to cut and weld again to make up for the missing length, which is time-consuming and laborious.

[0003] CN220488572U discloses an adjustable threaded pipe joint structure. Through the cooperation between the rotating disk, the first screw rod and the sliding plate, it is convenient for the lifting plate to drive the two side plates to move downward, and at the same time, the two springs are compressed, and then it is convenient for the two threaded pipes to move horizontally. When the two springs reset, the lifting plate can drive the two side plates to move upward, so that the two positioning rods are respectively located in the two corresponding side plates, and then it is convenient to fix the two threaded pipes after moving, so as to conveniently change the distance between the two threaded pipes to connect the first pipe and the second pipe. It solves the problem that it is inconvenient to adjust the length of the joint to connect two pipes at present. However, when adjusting the length of the joint by the utility model, first rotate the first screw rod, then adjust the distance between the first pipe and the second pipe, and then rotate the first screw rod in the reverse direction to connect the positioning rod with the corresponding positioning hole. And after the adjustment is completed, it is necessary to lock the first pipe and the second pipe through the locking mechanism, and the adjustment is troublesome. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides an adjustable threaded pipe joint structure.

[0005] An adjustable threaded pipe joint structure includes an intermediate pipe. Adjusting pipes are provided at both ends of the intermediate pipe. Installation plates extending towards the middle and symmetrical to each other are provided on the two adjusting pipes. Rack teeth are provided on the opposite surfaces of the two installation plates. The two rack teeth are both engaged with a gear. The gear is installed on the intermediate pipe through a rotating shaft. A rotating head is provided at the top of the rotating shaft. The rotating head is cooperatively connected with a locking assembly.

[0006] Furthermore, a fixing frame is provided on the intermediate pipe. The top of the rotating shaft passes through the top wall of the fixing frame and is connected to the rotating head.

[0007] Further, the locking assembly includes a clamping plate which is slidably connected to the top wall of the fixed frame. One end of the clamping plate away from the rotating head is connected to a clamping screw, and the clamping screw is cooperatively connected to a fixing plate which is fixedly installed on the fixed frame.

[0008] Further, the clamping plate is an arc-shaped structure adapted to the rotating head, and an anti-slip layer is provided on the side of the clamping plate close to the rotating head.

[0009] Further, one end of the adjusting pipe away from the central pipe is provided with a connecting portion connected to the threaded pipe. The connecting portion is provided with internal threads, and a ring-shaped protrusion is provided at the connection between the adjusting pipe and the connecting portion. A first sealing gasket is provided on the ring-shaped protrusion.

[0010] Further, a plurality of second sealing gaskets are provided at the connection between the adjusting pipe and the intermediate pipe.

[0011] Due to the adoption of the above technical solutions, the beneficial technical effects of the present utility model are as follows: When the distance between the two threaded pipes is large in the present utility model, by screwing the rotating head, the gear is driven to rotate. The rotation of the gear drives the rack to move to both sides, so that the two adjusting pipes move to both sides simultaneously, thus facilitating the adaptation to the distance between the two threaded pipes. When the distance between the two threaded pipes is close, the rotating head is screwed in the reverse direction to adapt to the distance between the two threaded pipes, and the adjustment is convenient.

Detailed implementation mode

[0020] To more clearly illustrate the technical solution of the present invention, the present invention will be further described below in conjunction with the attached drawings. Obviously, the attached drawings described below are only one embodiment of the present invention. For those of ordinary skill in the art, without creative work, other embodiments obtained based on this drawing and embodiment all fall within the protection scope of the present invention.

[0021] According to Figure 1-7 As shown, an adjustable threaded pipe joint structure includes a middle pipe 1. Both ends of the middle pipe 1 are provided with adjustment pipes 2. Both of the two adjustment pipes 2 are provided with mounting plates 3 that extend towards the middle and are symmetrical to each other. Rack bars 4 are provided on the opposite surfaces of the two mounting plates 3. Both of the two rack bars 4 are engaged with a gear 5. The gear 5 is installed on the middle pipe 1 through a rotating shaft 6. A rotating head 7 is provided at the top of the rotating shaft 6. The rotating head 7 is connected with a locking assembly in a matching manner.

[0022] In the above specific technical solution, when the distance between two threaded pipes is large, by screwing the rotating head 7, the gear 5 is driven to rotate. By the rotation of the gear 5, the rack bars 4 are driven to move towards both sides, so that the two adjustment pipes 2 move towards both sides at the same time, thus facilitating the adaptation to the distance between the two threaded pipes. When the distance between the two threaded pipes is close, the rotating head 7 is screwed in the reverse direction to adapt to the distance between the two threaded pipes, and the adjustment is convenient.

[0023] A fixing bracket 8 is provided on the middle pipe 1. The top of the rotating shaft 6 passes through the top wall of the fixing bracket 8 and is connected with the rotating head 7.

[0024] The locking assembly includes a clamping plate 9. The clamping plate 9 is slidably connected to the top wall of the fixing bracket 8. One end of the clamping plate 9 away from the rotating head 7 is connected with a clamping screw 10. The clamping screw 10 is connected with a fixing plate 11 in a matching manner. The fixing plate 11 is fixedly installed on the fixing bracket 8.

[0025] In the above specific technical solution, to prevent the gear 5 from rotating due to the force on the threaded pipe, resulting in the loosening of the connection between the adjustment pipe 2 and the central pipe, a locking assembly is provided. By rotating the clamping screw 10, the clamping plate 9 is tightly abutted against the rotating head 7, thus playing a locking role on the gear 5.

[0026] The clamping plate 9 is an arc-shaped structure adapted to the rotating head 7, and an anti-slip layer is provided on one side of the clamping plate 9 close to the rotating head 7, which improves the locking effect of the clamping plate 9.

[0027] One end of the adjusting pipe 2 away from the central pipe is provided with a connecting portion 12 connected to the threaded pipe. The connecting portion 12 is provided with internal threads. A ring-shaped protrusion 13 is provided at the connection between the adjusting pipe 2 and the connecting portion 12. A first sealing gasket 14 is provided on the ring-shaped protrusion 13, ensuring the sealing performance of the joint.

[0028] A plurality of second sealing gaskets 15 are provided at the connection between the adjusting pipe 2 and the intermediate pipe 1, ensuring the sealing performance of the joint.

[0029] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
