Description

Technical Field

[0001] This application relates to the field of inclinometer protection, and more specifically, to an underground connecting wall inclinometer connector. Background Technology

[0002] Currently, sandy soil piles are also known as SMW piles. The SMW method involves drilling to a certain depth on-site using a multi-axis drilling and mixing machine, while simultaneously spraying a cement-based reinforcing agent at the drill bit to repeatedly mix with the foundation soil. Overlapping construction is adopted between each construction unit. Before the cement-soil mixture hardens, H-beams or steel plates are inserted as stress reinforcement materials. Once the cement hardens, a continuous, complete, and seamless underground wall with a certain strength and rigidity is formed. To ensure the quality of construction, an inclinometer tube needs to be fixed on one side of the H-beam when it is installed.

[0003] Authorization announcement number CN222758965u, authorized announcement date 2025.04.15, discloses an anti-buoyancy and anti-pressure device for fixed inclinometer tubes of construction piles in sandy strata. Specifically, it relates to the field of inclinometer tube protection technology, including a construction pile steel body with multiple inclinometer tubes arranged on the outer side of its inner end. The construction pile steel body has a first support base at the middle of the end near the inclinometer tubes, and a first limiting connector at the outer end of the first support base. The construction pile steel body also has a second support base at the middle of the middle of the end near the inclinometer tubes. In actual use, by correspondingly setting the limiting locking sleeve, the first limiting connector, the concave limiting groove, and the first protective pad, the connection between two inclinometer tubes can be effectively clamped and fixed, allowing the concave limiting groove to abut against one end of the flared sleeve. This effectively prevents the inclinometer tubes from floating due to excessive underground pressure during installation.

[0004] The existing technical solutions described above have the following drawbacks: the outer ends of the first limiting connector, the second limiting connector, and the limiting locking sleeve are all provided with locking lugs, and locking bolts are used to lock and fix the locking lugs, which is cumbersome to operate. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a connecting component for an underground connecting wall inclinometer, which aims to improve the problem of cumbersome operation when using locking bolts to lock and fix the locking lugs.

[0006] This application provides a connection component for an underground connecting wall inclinometer tube, including a base, a snap-fit ​​structure, a hinge assembly, and a linkage block;

[0007] The snap-fit ​​structure includes a support base and a snap-fit ​​base. The support base is fixed with a snap-fit ​​bar, which is inclined. The snap-fit ​​base has a guide groove, which cooperates with the snap-fit ​​bar to slide and snap-fit.

[0008] The hinge assembly includes a fixed hinge lug, a movable hinge lug, and a rotating shaft. The fixed hinge lug is fixedly connected to the base, and the movable hinge lug is fixedly connected to the support base. The movable hinge lug rotates relative to the fixed hinge lug around the rotating shaft.

[0009] The upper end of the linkage block is rotatably connected to the support base. The lower end of the linkage block is provided with a first contact surface and a second contact surface on both sides. The first contact surface is corresponding to the end of the snap-fit ​​base, and the second contact surface is opposite to the fixed hinge lug.

[0010] In a preferred embodiment of this invention, the base surface is provided with multiple mounting holes, which are distributed at various corners of the base. The mounting holes can be used to fix the base to the H-beam using screws or by welding.

[0011] In a preferred embodiment of this utility model, the card strips are symmetrically arranged on both sides of the support base, the guide grooves are arranged one-to-one with the card strips, and the guide grooves are inclined in relation to the card strips.

[0012] In a preferred embodiment of this utility model, the surface of the support base is provided with a V-shaped groove, and the inner surface of the snap-fit ​​base is a semi-circular groove, with the V-shaped groove and the semi-circular groove on the inner surface of the snap-fit ​​base being arranged opposite to each other.

[0013] In a preferred embodiment of this utility model, two fixed hinge ears are provided, and the two fixed hinge ears are symmetrically arranged on both sides of the base, with each fixed hinge ear corresponding to a movable hinge ear.

[0014] In a preferred embodiment of this utility model, a first rotating hole is provided on the surface of the fixed hinge ear, a second rotating hole is provided on the surface of the movable hinge ear, the rotating shaft rotates through the first rotating hole and the second rotating hole, and a retaining spring is respectively engaged at both ends of the rotating shaft.

[0015] In a preferred embodiment of this utility model, an elastic element is connected between the lower end of the linkage block and the support base, and the elastic element is used to push the second contact surface away from the surface of the fixed hinge lug.

[0016] In a preferred embodiment of this utility model, the surface of the support base is provided with a receiving groove, and the upper end of the linkage block is rotatably disposed in the receiving groove via a pin. The first contact surface is provided with a helical tooth, the second contact surface is provided with a first anti-slip texture, and the surface of the fixed hinge lug is provided with a second anti-slip texture. The first anti-slip texture and the second anti-slip texture fit together. By the helical tooth engaging with the end of the locking seat, a locking effect is achieved. By adding anti-slip texture, the friction at the contact point between the second contact surface and the fixed hinge lug is increased, achieving a stable locking effect.

[0017] Beneficial effects: This application provides a connector for inclinometer tubes used in underground connecting walls. The tube to be connected is placed against the surface of the support base. The lower end of the guide groove is aligned with the upper end of the clamping strip by hand-held clamping seat. The clamping seat is fixed to the surface of the support base by sliding insertion, thereby clamping and fixing the tube. Since the clamping strip is inclined, the clamping seat clamps and secures the tube as it slides down along the strip. No screws are required for connection and fixing, making operation convenient and improving work efficiency.

[0018] When multiple long tubes are joined together, they will deform along their length, resulting in twisting and misalignment, making proper fixation impossible. The support base allows for rotation around the fixed hinge lug via a movable hinge lug, facilitating angle adjustment to accommodate twisting and misalignment and enabling installation in different situations. After the snap-fit ​​bracket engages with the support base, the end of the snap-fit ​​bracket pushes the first contact surface, causing the second contact surface to fit tightly against the fixed hinge lug, locking the rotation angle and preventing rotation and wobbling after installation, thus ensuring installation stability.

[0033] The hinge assembly 500 includes a fixed hinge lug 510, a movable hinge lug 530, and a rotating shaft 550. The fixed hinge lug 510 is fixedly connected to the base 100, and the movable hinge lug 530 is fixedly connected to the support base 310. The movable hinge lug 530 rotates relative to the fixed hinge lug 510 around the rotating shaft 550.

[0034] The upper end of the linkage block 700 is rotatably connected to the support base 310. The lower end of the linkage block 700 is provided with a first contact surface 701 and a second contact surface 703 on both sides. The first contact surface 701 is corresponding to the end of the snap-fit ​​base 330, and the second contact surface 703 is opposite to the fixed hinge lug 510.

[0035] In a specific embodiment of this utility model, the base 100 has mounting holes 110 on its surface. Multiple mounting holes 110 are provided and distributed at various corners of the base 100. The mounting holes 110 can be fixed to the H-beam using screws or by welding.

[0036] In a specific embodiment of this utility model, the card strips 311 are symmetrically arranged on both sides of the support base 310, and the guide grooves 331 are arranged in a one-to-one correspondence with the card strips 311, and the guide grooves 331 are inclined in a corresponding manner to the card strips 311.

[0037] In a specific embodiment of this utility model, the surface of the support base 310 is provided with a V-shaped groove 313, and the inner surface of the snap-fit ​​base 330 is a semi-circular groove. The V-shaped groove 313 and the semi-circular groove on the inner surface of the snap-fit ​​base 330 are arranged opposite to each other.

[0038] In a specific embodiment of this utility model, two fixed hinge ears 510 are provided, and the two fixed hinge ears 510 are symmetrically arranged on both sides of the base 100. The fixed hinge ears 510 and the movable hinge ears 530 are arranged in a one-to-one correspondence.

[0039] In a specific embodiment of this utility model, the fixed hinge ear 510 has a first rotating hole on its surface, the movable hinge ear 530 has a second rotating hole on its surface, the rotating shaft 550 rotates through the first rotating hole and the second rotating hole, and the two ends of the rotating shaft 550 are respectively engaged with snap rings.

[0040] In a specific embodiment of this utility model, an elastic element 710 is connected between the lower end of the linkage block 700 and the support base 310. The elastic element 710 is used to push the second contact surface 703 away from the surface of the fixed hinge lug 510.

[0041] In a specific embodiment of this utility model, the support base 310 has a receiving groove 315 on its surface, and the upper end of the linkage block 700 is rotatably disposed in the receiving groove 315 via a pin 730. The first contact surface 701 has a helical toothed portion, the second contact surface 703 has a first anti-slip texture, and the fixed hinge ear 510 has a second anti-slip texture. The first anti-slip texture and the second anti-slip texture fit together.

By adding anti-slip texture, the frictional force at the contact point between the second contact surface 703 and the fixed hinge ear 510 is increased, achieving a stable locking effect.

[0042] The working principle of this underground inclinometer wall connector is as follows: During use, the pipe to be connected is placed against the surface of the support base 310. The lower end of the guide groove 331 is aligned with the upper end of the clamping strip 311 by holding the clamping seat 330. The clamping seat 330 is then fixed to the surface of the support base 310 through a sliding connection, thus clamping and securing the pipe. Since the clamping strip 311 is inclined, the clamping seat 330 clamps and secures the pipe as it slides down along the strip 311. No screws are required for connection and fixation, making operation convenient and improving work efficiency.

[0043] When multiple long tubes are joined together, they will deform along their length, resulting in twisting and misalignment, making proper fixation impossible. The support base 310 can rotate around the fixed hinge ear 510 via the movable hinge ear 530, facilitating angle adjustment to accommodate twisting and misalignment and achieve different installation states. After the snap-fit ​​seat 330 snaps into the support base 310, the end of the snap-fit ​​seat 330 pushes the first contact surface 701, causing the second contact surface 703 to fit tightly against the fixed hinge ear 510, locking the rotation angle and preventing rotation and shaking after installation, thus achieving installation stability.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
