Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, and in particular to a detachable connector. Background Technology

[0002] Pipelines are fluid devices used to transport gases, liquids, or solid particles, and are widely used in water supply, drainage, heating, gas supply, and other fields.

[0003] During pipeline assembly, the length of a single pipe section is often insufficient to meet the overall pipeline requirements, necessitating the assembly and splicing of multiple pipe sections. Existing grooved connections are widely used for the installation and fixing of two pipe sections due to their advantages of quick, simple, and safe installation. However, existing grooved connection fixing typically uses bolts and nuts for connection and fixing. When fixing the bolts and nuts, the grooved connector needs to be fitted and fixed, and then external auxiliary tools such as wrenches are used to fix and rotate the bolts and nuts respectively. This process wastes a lot of time, resulting in low connection efficiency. At the same time, bolted connections cannot guarantee the state of the grooved connection. If the bolt connection is not in place, the sealing cannot be guaranteed; if the bolt connection is excessive, it will cause damage to the grooved components, further affecting the installation effect.

[0004] Therefore, we provide a detachable connector. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a detachable connector that facilitates the connection of grooved components and ensures stability after connection.

[0006] In view of this, the present invention provides a detachable connector, including a conveying pipe. The conveying pipe is provided with a first half-hoop and a second half-hoop. The outer surfaces of the first half-hoop and the second half-hoop are respectively symmetrically provided with two first connecting ears and two second connecting ears. The upper surfaces of the first connecting ears and the second connecting ears are respectively provided with threaded holes and fixing holes. A screw cylinder is installed at the lower end of the first connecting ear, and a fixing cylinder is installed at the lower end of the screw cylinder. The inner wall of the fixing cylinder is provided with a plurality of circular movable grooves. The circular movable grooves are movably provided with retaining beads. Limiting posts are provided between the plurality of retaining beads. A plurality of elastic limiting blocks are provided on the outside of the limiting posts. The inner wall of the fixing hole is provided with a plurality of arc-shaped grooves.

[0007] Preferably, when fixing the conveying pipe, the first half-hoop and the second half-hoop are symmetrically distributed, the adjacent end surfaces of the first half-hoop and the second half-hoop are in a fitted state, and the inner diameter of the screw hole is smaller than the inner diameter of the fixing hole.

[0008] Preferably, the screw hole, the screw cylinder, and the fixing cylinder are concentrically arranged and are through-type. The screw cylinder is located between the first connecting lug and the second connecting lug. The fixing cylinder is inserted into the fixing hole, and the outer surface of the fixing cylinder is in contact with the inner wall of the fixing hole. A portion of the outer surface of the retaining bead is engaged with the arc-shaped groove, and the outer surface of the retaining bead is in close contact with the inner wall of the arc-shaped groove.

[0009] Preferably, the limiting post is inserted into the inside of the fixing cylinder, and the outer surface of the limiting post is in contact with the inner wall of the fixing cylinder. When the second half hoop is connected to the first half hoop, the outer surfaces of several of the retaining beads are simultaneously in contact with the outer surface of the limiting post.

[0010] Preferably, the elastic limiting block is installed on the lower end surface of the fixed cylinder, and a plurality of elastic limiting blocks are distributed circumferentially at equal intervals. The outer surface of the plurality of elastic limiting blocks forms a conical shape, and the inner wall of the plurality of elastic limiting blocks is simultaneously in contact with the outer surface of the limiting post. The end with the smallest diameter of the elastic limiting block is fixedly connected to the fixed cylinder, and the outer diameter of the end with the smallest diameter of the elastic limiting block is consistent with the inner diameter of the fixing hole.

[0011] Preferably, a bolt is fixedly installed at the upper end of the limiting post, and the bolt is threadedly connected to both the screw hole and the screw cylinder.

[0012] Preferably, positioning grooves are respectively formed on the two ends of the first half-hoop, and positioning blocks are inserted into the positioning grooves. The positioning blocks are fixedly connected to the second half-hoop.

[0013] Compared with the prior art, the present invention provides a detachable connector, which has the following advantages:

[0014] 1. In this utility model, when fixing the first half hoop and the second half hoop, it is only necessary to insert and rotate to quickly complete the connection and fixation of the first half hoop and the second half hoop. When fixing the first half hoop and the second half hoop, it is not necessary to use too many external auxiliary tools, making the connection process simple and convenient, and further improving the efficiency of pipeline installation.

[0015] 2.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example: A detachable connector, such as Figures 1-4As shown, the device includes a conveying pipe 1, with a first half-hoop 2 and a second half-hoop 3 on the outside of the conveying pipe 1. The outer surfaces of the first half-hoop 2 and the second half-hoop 3 are symmetrically provided with two first connecting ears 4 and two second connecting ears 5. The upper surfaces of the first connecting ears 4 and the second connecting ears 5 are respectively provided with a screw hole 401 and a fixing hole 501. A screw cylinder 6 is installed at the lower end of the first connecting ear 4, and a fixing cylinder 7 is installed at the lower end of the screw cylinder 6. The inner wall of the fixing cylinder 7 is provided with several circular movable grooves 701. A retaining bead 8 is movably arranged inside the circular movable grooves 701. Limiting posts 10 are provided between the several retaining beads 8. Several elastic limiting blocks 11 are provided on the outside of the limiting posts 10. Several arc-shaped retaining grooves 502 are provided on the inner wall of the fixing hole 501.

[0025] When the conveying pipe 1 is fixed, the first half hoop 2 and the second half hoop 3 are symmetrically distributed, and the adjacent end surfaces of the first half hoop 2 and the second half hoop 3 are in a fitted state. The inner diameter of the screw hole 401 is smaller than the inner diameter of the fixing hole 501.

[0026] The screw hole 401, screw cylinder 6, and fixing cylinder 7 are concentrically arranged and are through-connected. The screw cylinder 6 is located between the first connecting ear 4 and the second connecting ear 5. The fixing cylinder 7 is inserted into the fixing hole 501, and the outer surface of the fixing cylinder 7 is in contact with the inner wall of the fixing hole 501. Part of the outer surface of the retaining bead 8 is engaged with the inside of the arc-shaped retaining groove 502, and the outer surface of the retaining bead 8 is in close contact with the inner wall of the arc-shaped retaining groove 502.

[0027] The limiting post 10 is inserted into the inside of the fixed cylinder 7. The outer surface of the limiting post 10 is in contact with the inner wall of the fixed cylinder 7. When the second half hoop 3 is connected to the first half hoop 2, the outer surfaces of several locking beads 8 are simultaneously in contact with the outer surface of the limiting post 10.

[0028] The elastic limiting block 11 is installed on the lower end surface of the fixed cylinder 7. Several elastic limiting blocks 11 are distributed circumferentially at equal intervals. The outer surface of several elastic limiting blocks 11 forms a conical shape. The inner wall of several elastic limiting blocks 11 is simultaneously attached to the outer surface of the limiting post 10. The end with the smallest diameter of the elastic limiting block 11 is fixedly connected to the fixed cylinder 7. The outer diameter of the end with the smallest diameter of the elastic limiting block 11 is consistent with the inner diameter of the fixing hole 501.

[0029] A bolt 9 is fixedly installed on the upper end of the limiting post 10. The bolt 9 is threadedly connected to both the screw hole 401 and the screw cylinder 6.

[0030] To ensure the stability of the connection between the first half-hoop 2 and the second half-hoop 3, precise alignment of the two conveying pipes 1 is required. Then, to ensure stability after alignment, the first half-hoop 2 and the second half-hoop 3 are snapped together at the connection point of the two conveying pipes 1. To ensure stability after the first half-hoop 2 and the second half-hoop 3 are fitted together, a retaining bead 8 is initially snapped into the fixing hole 501. During the docking process of the first half-hoop 2 and the second half-hoop 3, the screw cylinder 6 at the lower end of the first connecting lug 4 and the fixing cylinder 7 will move synchronously towards the fixing hole 501. When the first half-hoop 2 and the second half-hoop 3 are fitted together, the fixing cylinder 7 is inserted into the fixing hole 501. Inside, the arc-shaped groove 502 and the ball 8 are on the same horizontal plane. To ensure that the ball 8 and the arc-shaped groove 502 are firmly connected, the limiting post 10 moves towards the ball 8. Based on the threaded connection between the bolt 9 and the screw hole 401 and the screw cylinder 6, rotating the bolt 9 can drive the limiting post 10 to move towards the ball 8. Under the pressure of the front end of the limiting post 10, the ball 8 will be pushed into the arc-shaped groove 502. The limiting post 10 can limit the ball 8 and ensure the stability of the connection between the ball 8 and the arc-shaped groove 502. If the first half-hoop 2 and the second half-hoop 3 are not in contact, the limiting post 10 cannot move downward and the first half-hoop 2 and the second half-hoop 3 cannot be fixed.

[0031] At this point, the initial connection and fixation of the first half-hoop 2 and the second half-hoop 3 are completed. To further ensure the stability of the connection between the first half-hoop 2 and the second half-hoop 3, an elastic limiting block 11 is installed at the front end of the fixing cylinder 7. When the elastic limiting block 11 contacts the upper end of the fixing hole 501, under the mutual squeezing action and the deformation of the elastic limiting block 11 itself, the elastic limiting block 11 will retract inward and enter the interior of the fixing hole 501. When the first half-hoop 2 is in contact with the second half-hoop 3, the elastic limiting block 11 is located outside the lower outer surface of the fixing hole 501. To prevent the elastic limiting block 11 from retracting inward, the limiting post 10 is moved further towards the elastic limiting block 11 by rotating the bolt 9 until the bolt 9 can no longer move. At this point, the limiting post 10 is located inside the elastic limiting block 11. The deformation of the elastic limiting block 11 is limited by the limiting post 10, ensuring the stability of the engagement between the elastic limiting block 11 and the lower end of the fixing hole 501. At the same time, the engagement between the elastic limiting block 11 and the outer end of the fixing hole 501 can fix the state after the first half hoop 2 and the second half hoop 3 are attached, which facilitates subsequent limiting and fixing.

[0032] The limiting post 10 limits the connection between the locking bead 8 and the arc-shaped locking groove 502, and the limiting post 10 further limits the connection between the elastic limiting block 11 and the fixing hole 501. First, when fixing the first half-hoop 2 and the second half-hoop 3, it is only necessary to insert and rotate to quickly complete the connection and fixation of the first half-hoop 2 and the second half-hoop 3. When fixing the first half-hoop 2 and the second half-hoop 3, it is not necessary to use too many external auxiliary tools, making the connection process simple and convenient, and further improving the efficiency of pipeline installation. Second, during the connection process of the first half-hoop 2 and the second half-hoop 3, the connection of the first half-hoop 2 and the second half-hoop 3 can only be completed after the first half-hoop 2 and the second half-hoop 3 are in contact, avoiding the situation of excessive or insufficient rotation of the bolt 7, and further ensuring the stability of the pipeline connection.

[0033] like Figures 1-4 As shown, positioning grooves 12 are respectively opened on the two ends of the first half hoop 2, and positioning blocks 13 are inserted into the positioning grooves 12. The positioning blocks 13 are fixedly connected to the second half hoop 3.

[0034] When the two conveying pipes 1 are fixed by the first half-hoop 2 and the second half-hoop 3, in order to ensure the accuracy of the docking between the first half-hoop 2 and the second half-hoop 3 and to avoid misalignment between the first half-hoop 2 and the second half-hoop 3, a positioning groove 12 and a positioning block 13 are provided at the mating ends of the first half-hoop 2 and the second half-hoop 3. The positioning groove 12 and the positioning block 13 are connected and positioned to ensure the accuracy of the docking position between the first half-hoop 2 and the second half-hoop 3.

[0035] 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.
