Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0032] See Figures 1 to 5 As shown, a new type of semi-automatic quick-locking pipe structure includes an outer tube 1 and an inner tube 2. In this embodiment, both the outer tube and the inner tube are conventional structures of the prior art, and are only simply applied. Moreover, the outer diameter of the inner tube matches the inner diameter of the outer tube, and the inner tube can be telescopically adjusted within the outer tube. The end of the inner tube can be telescopically inserted into the outer tube. A limit end cap 3 is provided at the end of the outer tube away from the insertion end of the inner tube, and a pipe plug 4 is provided at the end of the inner tube away from the outer tube. In this embodiment, the limit end cap and the pipe plug are at both ends of the overall structure, mainly for the installation of the return spring. In the actual application process, several locking grooves 5 are provided on the side surface of the inner tube in a straight line. At the same time, a return spring 6 is provided at the center of the outer tube and the inner tube, and both ends of the return spring are respectively abutted against the limit end cap and the pipe plug. The return spring is mainly used to achieve semi-automatic quick reset during reset, improving the convenience of use.

[0033] Furthermore, in the actual application process, a locking structure 7 is provided at the end of the outer tube, and the end of the inner tube passes through the locking structure and extends into the outer tube. During assembly, the locking structure is snapped into the locking groove for positioning. When the locking structure is pressed, the elastic force of the return spring causes the outer tube and the inner tube to elongate and reset.

[0034] Moreover, in this embodiment, the locking structure includes a connecting sleeve 71, a limiting connecting ring 72, a button ring 73, a return compression spring 74, and a locking strip-shaped block 75. The locking strip-shaped block is positioned through the connecting sleeve under the action of the return compression spring and is positioned with the locking groove. When the button ring is pressed, the return compression spring is compressed and stores energy. At the same time, the locking strip-shaped block disengages from the locking groove, and at this time, the inner tube can be telescopically adjusted within the outer tube.

[0035] In the actual application process, a convex ring 8 is integrally formed on the end face of the connecting sleeve. Guide planes 9 are provided on the symmetric sides of the convex ring. A locking strip-shaped groove 10 communicating with the inner hole of the connecting sleeve is provided on the connecting sleeve. Limiting planes 11 matching with the guide planes are provided on the symmetric inner walls of the button ring, and a C-shaped card slot 12 is provided at the end of the limiting convex surface. During assembly, the locking strip-shaped block is arranged in the button ring and is respectively clamped into the C-shaped card slots at both ends for positioning. The button ring is sleeved on the convex ring and is limited by the limiting connecting ring connected to the end of the convex ring. The outer tube is fixed to the end of the connecting sleeve, and the inner tube passes through the connecting sleeve and extends into the outer tube. During use, the locking strip-shaped block is at the locking strip-shaped groove, the return compression spring is between the button ring and the connecting sleeve, and under the action of the return compression spring, the button ring makes the locking strip-shaped block pass through the locking strip-shaped groove and extend into the interior of the connecting sleeve and be clamped into the locking groove of the outer tube. In the actual application process, the inner cavity length of the button ring is greater than the outer diameter of the convex ring, and the locking strip-shaped block and the return compression spring are symmetrically located at both ends of the diameter of the button ring. The limiting plane adheres to the guide plane. Since the locking strip-shaped block and the return compression spring are at both ends of the diameter of the button ring, under the action of the return compression spring, the locking strip-shaped block will be clamped into the locking groove, and when pressed, it is guided by the limiting plane and the guide plane to prevent tilting or displacement, so that the locking strip-shaped block can be loosened from or clamped into the locking groove, ensuring the smoothness and effectiveness of the pressing operation.

[0036] In the actual application process, the limiting connecting ring is fixedly connected to the convex ring by threading. The connecting sleeve, the limiting connecting ring, and the button ring are all metal structures, and the locking strip-shaped block is a metal structure. Through the above structure, the smoothness and effectiveness of use can be ensured.

[0037] At the same time, a card hole 13 is provided at the end of the outer tube. A card block is fixed on the inner wall of the limiting end cover. During installation, the limiting end cover is sleeved on the end of the outer tube, and the card block is clamped into the card hole for positioning. Ensure the smoothness and reliability of the installation of the limiting end cover, and it will not loosen or fall off when the return spring is compressed.

[0038] The utility model has positive effects: the structure of the utility model is reasonably arranged. By arranging a reset spring in cooperation with a locking structure and a locking groove, when the inner tube and the outer tube contract, the reset spring will be compressed, and the locking structure can be clamped into the locking groove for positioning, ensuring the convenience and stability of the contraction adjustment. Moreover, when reset is required, only the locking structure needs to be controlled, and the elongation can be completed by resetting under the action of the reset spring, improving the convenience of use and the semi-automatic reset property, enhancing the efficiency of the elongation and reset, and having strong applicability and good practicability.

[0039] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the specification, they can also be directly processed without any doubt according to the existing technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt the conventional models in the existing technology, so no specific description will be made here.

[0040] Obviously, the above embodiments of the present utility model are only examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And these obvious changes or variations derived from the essential spirit of the present utility model still belong to the protection scope of the present utility model.
