Description

Technical Field

[0001] The utility model relates to an end plate mechanical connector, in particular to an end plate mechanical connector. Background Art

[0002] With the development of economic construction, concrete pipe pullout piles are becoming widely used in various fields, and demand is growing. Adjacent pullout piles, where geological design requirements are met, require connection joints. Conventional mechanical quick-connect endplate connectors for prestressed concrete pipe pullout piles are inconvenient for quick assembly and lack sufficient pullout resistance. To address this issue, a mechanical endplate connector was proposed. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems and to provide an end plate mechanical connector.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: an end plate mechanical connector, comprising a mounting box provided with an inner cavity and two clamping blocks movably installed in the mounting box and arranged in a split manner; the connector is characterized in that it also includes a spring group installed between the clamping block and the side wall of the mounting box, wherein the spring group includes an inner spring and an outer spring located outside the inner spring.

[0005] More preferably, it further includes a boss disposed in the installation box for limiting the position of the spring assembly.

[0006] Further preferably, the boss and the installation box are integrally formed or formed by stamping.

[0007] More preferably, it also includes a connecting rod installed in the two blocks.

[0008] Further preferably, the clamping block is provided with a plurality of conical clamping grooves arranged in a conical shape, and one end of the connecting rod is provided with a plurality of conical clamping teeth adapted to the conical clamping grooves.

[0009] The beneficial effects of the utility model are as follows: by arranging two separate clamping blocks and a spring group between the two clamping blocks and the installation box, the two clamping blocks are pressed against and clamped to the connecting rod by the squeezing force of the spring group on the clamping blocks, which facilitates installation and connection. At the same time, the spring group increases the elastic thrust through the arrangement of the inner spring and the outer spring, thereby enhancing the clamping force between the clamping block and the connecting rod and enhancing the pull-out resistance.

[0010] By arranging a boss for limiting the position of the spring group on the installation box, the position of the spring group is limited by the arrangement of the boss, thereby preventing the spring group from falling out of the installation box. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Next, we will further explain the end plate mechanical connector of the present invention with reference to the accompanying drawings.

[0017] It should be noted that all directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0018] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; it can mean mechanical connection or electrical connection; it can mean direct connection or indirect connection through an intermediate medium; it can mean internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0019] See Figure 1-Figure 4 As shown in the figure, an end plate mechanical connector includes a mounting box 1 with an inner cavity and two clamping blocks 2 movably mounted in the mounting box 1 and arranged in a separate manner; the connector is characterized by further including a spring group 3 mounted between the clamping blocks 2 and the side wall of the mounting box 1, wherein the spring group 3 is composed of an inner spring 31 in the inner ring and an outer spring 32 on the outside of the inner spring 31;

[0020] By providing two separate clamping blocks 2 and a spring group 3 between the two clamping blocks 2 and the mounting box 1, the spring group 3 exerts an extrusion force on the clamping blocks 2, causing the two clamping blocks 2 to cling to and clamp the connecting rod 5, thereby facilitating installation and connection assembly. At the same time, the spring group 3 increases the elastic thrust through the arrangement of the inner spring 31 and the outer spring 32, thereby enhancing the clamping force between the clamping block 2 and the connecting rod 5 and thus enhancing the pull-out resistance.

[0021] In one embodiment, the mounting box 1 further includes a boss 4 for limiting the position of the spring assembly 3.

[0022] By arranging a boss 4 on the installation box 1 for limiting the position of the spring group 3 , the position of the spring group 3 is limited by the arrangement of the boss 4 , thereby preventing the spring group 3 from falling out of the installation box 1 .

[0023] In one embodiment, the boss 4 is formed integrally with the installation box 1, or is formed by punching the side wall of the installation box 1 inwardly to protrude the boss 4. The integrated design has fewer overall components and higher overall strength.

[0024] In one embodiment, it also includes a connecting rod 5 installed in the two blocks 2; the blocks 2 are provided with a plurality of conical grooves 6 arranged in a conical shape, and one end of the connecting rod 5 is provided with a plurality of conical teeth 7 adapted to the conical grooves 6; the connecting rod 5 and the blocks 2 are connected through the cooperation of the conical grooves 6 and the conical teeth 7, and the conical grooves 6 and the conical teeth 7 are both inclined downward, which facilitates the connection between the blocks 2 and the connecting rod 5 while enhancing the pull-out resistance.

[0025] When the utility model is in use: first, the inner spring 31 and the outer spring 32 are assembled into a spring group 3, and then installed into the installation box 1 and one end is limited by the boss 4. Then the two clamping blocks 2 are installed in the installation box 1 and are located between the two spring groups 3. When installing the connecting rod 5, it is only necessary to point the end with the conical clamping teeth 7 toward the clamping block 2 and form a downward extrusion force on it, driving the two clamping blocks 2 to move to both sides to squeeze the spring group 3 and then move downward until one end of the connecting rod 5 is installed to the bottom. At this time, the conical clamping groove 6 on the clamping block 2 cooperates with the conical clamping block 2 on the connecting rod 5 and clamps the connecting rod 5 through the elastic force of the spring groups 3 on both sides.

[0026] The protection scope of the present invention is not limited to the above embodiment and its variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment fall within the protection scope of the present invention.
