Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connectors, and more specifically, to a pull - out nut pipe plug. Background Technique

[0002] A bracket is a device used to support or maintain the structural stability of an object, and can be widely used in fields such as medicine, industry, and life. In medicine, brackets are mainly used to support narrow or dilated tissue lumens, such as blood vessels, tracheas, etc., to restore their normal physiological functions. Brackets in industry are used to support various equipment, pipelines, etc., to ensure their stable operation. Brackets in life can be seen in various furniture, electrical appliances and other equipment, used to improve the convenience and stability of use.

[0003] The sleeve expansion type fixed connector for a bracket is a special connecting device used to connect connecting pipe one and connecting pipe two through the connector.

[0004] Among them, through retrieval, it is found that the patent with the patent application number CN201821031948.3 discloses a sleeve expansion type fixed connector for a bracket, which mainly consists of a connecting pipe, a connecting rod and a sleeve. Its characteristics are as follows: the connecting pipe includes connecting pipe one and connecting pipe two, and connecting pipe one and connecting pipe two are connected through the connecting rod and the sleeve; the sleeve is composed of a shell piece on the outer ring and a skeleton inside, and the sleeve is movably installed on the outer ring of the connecting rod;

[0005] When this structure is in use, rotate connecting pipe one clockwise, and connecting pipe one drives the connecting rod to rotate together. At this time, the sleeve sleeved on the connecting rod will continuously move to the left. Because the diameter of the connecting rod to the left is continuously increasing, the sleeve sleeved on the connecting rod will be continuously expanded outwards, and the frictional force between the sleeve and the inner wall of connecting pipe two will also continuously increase, so that connecting pipe two can be firmly fixed; when disassembling, as long as connecting pipe one is rotated in the reverse direction to make the sleeve return to the initial state, connecting pipe two can be easily disassembled. However, this structure is not easy to lock during use, resulting in a low fixing effect and lack of convenience. Summary of the Utility Model

[0006] In order to overcome the above - mentioned defects of the prior art, the utility model provides a pull - out nut pipe plug, aiming to solve the problems raised in the above - mentioned background technique.

[0007] To achieve the above - mentioned purpose, the utility model provides the following technical solution: a pull - out nut pipe plug, including a reinforced pipe body, and a positioning connection assembly is arranged on the reinforced pipe body;

[0008] The positioning and connecting component includes a limiting plate body arranged at one end of the reinforcing pipe body. A number of reinforcing elastic baffles are distributed on the limiting plate body, and each of the reinforcing elastic baffles is located in the middle of the reinforcing pipe body. A number of limiting abutting blocks are arranged on one side of each of the multiple reinforcing elastic baffles;

[0009] A reinforcing pulling member is arranged between the multiple reinforcing elastic baffles. The vertical cross-sectional shape of the reinforcing pulling member is trapezoidal. A through hole is penetrated through the reinforcing pulling member. The outer side of the reinforcing pulling member extends to one side of the reinforcing elastic baffle and contacts the reinforcing elastic baffle. A limiting clamping groove is formed on the inner wall of the through hole, and an internal nut is arranged in the limiting clamping groove. The internal nut is clamped with the limiting clamping groove.

[0010] It can be seen that in the above technical solution, the internal nut can drive the reinforcing pulling member to displace between the multiple reinforcing elastic baffles through the traction force during the rotation of the bolt. When the reinforcing pulling member displaces, the outer side of the reinforcing pulling member contacts the reinforcing elastic baffle, so that the reinforcing elastic baffle can be deformed through the traction force during the displacement of the reinforcing pulling member, and then each limiting abutting block can be stuck in the positioning groove to position the reinforcing pipe bodies after they are sleeved together;

[0011] Optionally, in a possible implementation manner, a limiting sleeve is arranged at the bottom of the internal nut. The limiting sleeve is installed on the limiting plate body. The internal nut, the limiting sleeve, the limiting clamping groove and the through hole are all on the same central axis. A number of positioning grooves are penetrated through the outer side of the reinforcing pipe body, and each of the limiting abutting blocks extends into the corresponding positioning groove and is clamped with the positioning groove;

[0012] It can be seen that in the above technical solution, through the way of screw self-locking, it can effectively prevent the reinforcing elastic baffle from rebounding and causing the reinforcing pipe body to fall off. At the same time, the reinforcing elastic baffle is limited by the trapezoidal cross-section of the reinforcing pulling member, which can effectively ensure the stability when the reinforcing elastic baffle and the limiting abutting block limit the reinforcing pipe body.

[0013] The technical effects and advantages of the present utility model:

[0014] By arranging the positioning and connecting component, compared with the prior art, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of each structure and driven by rotating the bolt, the internal nut can drive the reinforcing pulling member to displace between the multiple reinforcing elastic baffles through the traction force during the rotation of the bolt. When the reinforcing pulling member displaces, the outer side of the reinforcing pulling member contacts the reinforcing elastic baffle, so that the reinforcing elastic baffle can be deformed through the traction force during the displacement of the reinforcing pulling member, and then each limiting abutting block can be stuck in the positioning groove to position the reinforcing pipe bodies after they are sleeved together;

[0015] Meanwhile, through the self-locking of the thread, it can effectively prevent the strengthened elastic baffle from rebounding and causing the strengthened pipe body to fall off. At the same time, the strengthened elastic baffle is limited by the trapezoidal cross-section of the strengthened pulling piece, which can effectively ensure the stability when the strengthened elastic baffle and the limiting abutting block limit the strengthened pipe body.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] As shown in the attached Figures 1-4The shown expansion nut pipe plug, through the positioning connection component arranged on the reinforcing pipe body 1, the inner nut 8 can drive the reinforcing pulling member 5 to displace between multiple reinforcing elastic baffles 3 under the traction force when the bolt rotates. When the reinforcing pulling member 5 displaces, the outer side of the reinforcing pulling member 5 contacts the reinforcing elastic baffle 3, so that the reinforcing elastic baffle 3 can deform under the traction force when the reinforcing pulling member 5 displaces. Then, each limiting abutting block 4 can be stuck in the positioning groove 10 to position the reinforcing pipe bodies 1 after being sleeved together. And the specific structure of the component is as follows;

[0024] The positioning connection component includes a limiting plate body 2 arranged at one end of the reinforcing pipe body 1. A number of reinforcing elastic baffles 3 are arranged and distributed on the limiting plate body 2, and each reinforcing elastic baffle 3 is located in the middle of the reinforcing pipe body 1. A number of limiting abutting blocks 4 are arranged on one side of each of the multiple reinforcing elastic baffles 3;

[0025] A reinforcing pulling member 5 is arranged between the multiple reinforcing elastic baffles 3. The vertical cross-sectional shape of the reinforcing pulling member 5 is trapezoidal. A through hole 6 is formed through the reinforcing pulling member 5. The outer side of the reinforcing pulling member 5 extends to one side of the reinforcing elastic baffle 3 and contacts the reinforcing elastic baffle 3. A limiting card slot 7 is formed on the inner wall of the through hole 6, and an inner nut 8 is arranged in the limiting card slot 7. The inner nut 8 is clamped with the limiting card slot 7.

[0026] A limiting sleeve 9 is arranged at the bottom of the inner nut 8. The limiting sleeve 9 is installed on the limiting plate body 2. The inner nut 8, the limiting sleeve 9, the limiting card slot 7 and the through hole 6 are all on the same central axis. A number of positioning grooves 10 are formed through the outer side of the reinforcing pipe body 1, and each limiting abutting block 4 extends into the corresponding positioning groove 10 and is clamped with the positioning groove 10.

[0027] During use according to the above structure, the staff installs the device at a specified position. When limiting the reinforcing pipe body 1, two reinforcing pipe bodies 1 are sleeved together, and a number of positioning grooves 10 are formed on the outer side of the reinforcing pipe body 1. The limiting abutting blocks 4 and the reinforcing pulling member 5 are placed in the reinforcing pipe body 1. Then, a bolt passes through the limiting sleeve 9 and extends into the inner nut 8. By driving through rotating the bolt, the inner nut 8 can drive the reinforcing pulling member 5 to displace between the multiple reinforcing elastic baffles 3 under the traction force when the bolt rotates. When the reinforcing pulling member 5 displaces, the outer side of the reinforcing pulling member 5 contacts the reinforcing elastic baffle 3, so that the reinforcing elastic baffle 3 can deform under the traction force when the reinforcing pulling member 5 displaces. Then, each limiting abutting block 4 can be stuck in the positioning groove 10 to position the reinforcing pipe bodies 1 after being sleeved together;

[0028] And through the way of screw self-locking, it can effectively avoid the rebound of the reinforcing elastic baffle 3 causing the detachment of the reinforcing pipe body 1. At the same time, the reinforcing elastic baffle 3 is limited by the trapezoidal cross-section of the reinforcing pull piece 5, which can effectively ensure the stability when the reinforcing elastic baffle 3 and the limiting abutment 4 limit the reinforcing pipe body 1.

[0029] Different from the prior art, the present application discloses an expansion nut pipe plug. The inner nut 8 can drive the reinforcing pull piece 5 to displace between multiple reinforcing elastic baffles 3 through the traction force during the rotation of the bolt. When the reinforcing pull piece 5 displaces, the outer side of the reinforcing pull piece 5 contacts the reinforcing elastic baffle 3, so that the reinforcing elastic baffle 3 deforms due to the traction force during the displacement of the reinforcing pull piece 5, and then each limiting abutment 4 can be stuck in the positioning groove 10 to position the reinforcing pipe body 1 after being sleeved together.

[0030] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
