Technical Field
[0001] This utility model relates to the field of universal joint mount technology, and in particular to a high-durability universal joint mount. Background Technology
[0002] In the field of civil engineering, static load testing of pile foundations is a crucial step in evaluating the bearing capacity of pile foundations, and the accuracy of displacement measurement directly affects the reliability of the test results. As an important support device for displacement measuring instruments, the performance of the universal joint base plays a vital role in the measurement accuracy. A high-durability universal joint base can provide a stable and adjustable mounting base for measuring instruments, ensuring that the instrument is always in the optimal measuring position during pile foundation settlement observation, thereby accurately capturing subtle displacement changes at the pile top or along the pile body, and providing strong data support for engineering quality assessment.
[0003] Existing universal joint bases typically employ a combination of a single universal ball joint and a connecting rod for adjustment. Multi-directional adjustment is achieved through the rotation of the universal ball joint at the end of the connecting rod. The underlying principle utilizes the clearance fit between the universal ball joint and the connecting hole, allowing the ball joint to rotate freely within a certain angle range, thereby adjusting the direction of the measuring instrument. Simultaneously, to ensure stability after adjustment, a locking bolt is usually installed at the connection point. Tightening the bolt compresses the universal ball joint, using friction to limit its rotation and maintain the instrument's positional stability.
[0004] However, existing technologies using a single universal ball joint and connecting rod combination suffer from wear and tear during long-term use due to frequent rotation between the universal ball and the connecting hole, leading to a gradual increase in the gap between them. Furthermore, the locking force of the locking bolts is difficult to maintain consistently and stably, easily resulting in loosening. This makes it impossible for the universal joint to maintain a stable adjustment state, thus affecting the positioning accuracy of the measuring instrument and causing inconvenience for displacement measurement in pile foundation static load tests. Therefore, a high-durability universal joint base is proposed to solve these problems. Utility Model Content
[0005] The purpose of this application is to provide a high-durability universal joint mount, which aims to improve the problem of easy loosening of the universal joint connection part in the existing universal joint mount.
[0006] Firstly, the high-durability universal joint base provided in this application adopts the following technical solution:
[0007] A high-durability universal joint base includes a base, an adjustment component provided on the side wall of the base, a mounting seat provided on the side wall of the base, and a fixing component provided on the side wall of the mounting seat.
[0008] The adjustment assembly includes multiple tapered connecting sleeves and universal balls. One tapered connecting sleeve has its sidewall fixedly connected to the upper surface of the base. Each universal ball has its sidewall fixedly connected to the upper surface of each tapered connecting sleeve. Each tapered connecting sleeve has a ball joint groove inside. Each tapered connecting sleeve has a butterfly spring inside. The sidewall of the butterfly spring is located inside the ball joint groove. Adjacent universal ball sidewalls are rotatably connected to adjacent ball joint grooves. Each universal ball sidewall is in contact with each butterfly spring sidewall. The mounting base sidewall is fixedly connected to one of the tapered connecting sleeve sidewalls.
[0009] By adopting the above technical solution, the meter head can be freely extended in any direction without the risk of loosening.
[0010] Preferably, the fixing component includes a clip, the sidewall of which is slidably connected inside the mounting base.
[0011] The above technical solution is used to achieve the effect of fixing the meter head.
[0012] Preferably, the side wall of the sleeve is fixedly connected to a handle, and the inner wall of the sleeve is provided with anti-slip texture.
[0013] By adopting the above technical solution, the jacket can be quickly pulled open, and at the same time, the friction between the jacket and the meter head is increased when fixing the meter head to prevent slippage.
[0014] Preferably, a connecting column is fixedly connected to the side wall of the jacket, and the side wall of the connecting column is slidably connected inside the mounting base.
[0015] By adopting the above technical solution, the sliding effect of the jacket is achieved.
[0016] Preferably, a connecting plate is fixedly connected to the side wall of the connecting column, and a rotating plate is rotatably connected inside the mounting base.
[0017] By adopting the above technical solution, the clips on both sides can slide simultaneously.
[0018] Preferably, a second rotating plate is rotatably connected between the first rotating plate and the connecting plate.
[0019] By adopting the above technical solution, the jacket is driven to slide towards the center, thereby clamping the dial indicator.
[0020] Preferably, a fixed base is fixedly connected inside the mounting base, and a compression spring is provided inside the mounting base. One end of the compression spring is fixedly connected to the side wall of the fixed base, and the other end of the compression spring is fixedly connected to the side wall of the connecting column.
[0021] The above technical solution is used to improve the installation effect of the spring.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. In this utility model, a serpentine hinge structure is formed by the cooperation of the conical connecting sleeve and the universal ball, and the butterfly spring in the ball hinge groove generates a continuous elastic force on the universal ball to compensate for the gap, so that the adjustment component can extend freely in any direction and is not easy to loosen after long-term use, thereby achieving a high-durability and stable adjustment effect. This solves the problem of easy loosening of the universal connection part of the existing universal gauge base. The above structure improves the stability and reliability of displacement measurement of the gauge base in scenarios such as pile foundation static load test.
[0024] 2. In this utility model, the handle drives the clamp and connecting column in a linkage, and the elastic force of the compression spring drives the clamp to clamp the meter head. The anti-slip texture on the inner wall of the clamp enhances the friction, so that the meter head can be quickly and securely fixed and easily disassembled. This solves the problems of cumbersome meter head fixing operation and easy loosening in the existing system. The above structure improves the efficiency and stability of meter head installation and disassembly. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.
[0033] Example 1: A high-durability universal joint base, referring to... Figures 1-3 It includes a base 1, which is made of metal and serves to provide stable support. The side wall of the base 1 is provided with an adjustment component for adjusting the position of the meter head. The side wall of the base 1 is provided with a mounting base 3, and the side wall of the mounting base 3 is provided with a fixing component for fixing the meter head.
[0034] The adjustment assembly includes multiple conical connecting sleeves 2 and universal balls 4. The conical connecting sleeves 2 and universal balls 4 cooperate to rotate at multiple angles, achieving a flexible adjustment of direction. One side wall of one conical connecting sleeve 2 is fixedly connected to the upper surface of the base 1, and the side wall of each universal ball 4 is fixedly connected to the upper surface of each conical connecting sleeve 2. The universal ball 4 is used to cooperate with the ball joint groove 5 to achieve rotation, allowing relative movement between the conical connecting sleeves 2. Each conical connecting sleeve 2 has a ball joint groove 5 inside, which is used to accommodate the universal ball 4 and provide it with rotation space to ensure the rotation effect of the universal ball 4. Each conical connecting sleeve 2 is provided with a butterfly spring 6 inside, which is used to apply a continuous elastic force to the universal ball 4. To compensate for gaps caused by long-term use and prevent loosening, the sidewall of the butterfly spring 6 is located inside the ball joint groove 5, and the sidewalls of adjacent universal balls 4 are rotatably connected inside the adjacent ball joint groove 5. The universal balls 4 rotate in conjunction with the ball joint groove 5, achieving the effect of allowing the adjustment component to extend in any direction. The sidewall of each universal ball 4 is in contact with the sidewall of each butterfly spring 6, and the butterfly spring 6 elastically compresses the universal ball 4, achieving the effect of keeping the universal ball 4 in close contact with the ball joint groove 5 and enhancing the connection stability. The sidewall of the mounting base 3 is fixedly connected to the sidewall of one of the conical connecting sleeves 2. The mounting base 3 moves together with the conical connecting sleeve 2 with the adjustment component, achieving the effect of driving the fixed component to adjust its position synchronously.
[0035] Example 2: A high-durability universal joint base, referring to... Figures 4-5 The fixing component includes a clamp 7, which is used to clamp the meter head to achieve the effect of fixing the meter head. The side wall of the clamp 7 is slidably connected to the inside of the mounting base 3. The clamp 7 moves in conjunction with the mounting base 3 to achieve the effect of opening and closing the clamp 7 to install and remove the meter head. A handle 8 is fixedly connected to the side wall of the clamp 7. The handle 8 is used for the user to hold and operate, which facilitates the movement of the clamp 7. The inner wall of the clamp 7 is provided with anti-slip texture 9. The anti-slip texture 9 is used to increase the friction between the clamp 7 and the meter head to prevent the meter head from slipping.
[0036] A connecting post 10 is fixedly connected to the side wall of the sleeve 7. The connecting post 10 connects the sleeve 7 to the connecting plate 11, transmitting power. The side wall of the connecting post 10 is slidably connected inside the mounting base 3. The connecting post 10 slides with the mounting base 3, achieving the effect of synchronously moving the sleeve 7. A connecting plate 11 is fixedly connected to the side wall of the connecting post 10. The connecting plate 11 connects the connecting post 10 to the rotating plate 13, transmitting force. A rotating plate 12 is rotatably connected inside the mounting base 3. The rotating plate 12 works with the rotating plate 13 to transmit power and change the direction of force. A rotating plate 2 is rotatably connected between the rotating plate 12 and the connecting plate 11. 13. Rotating plate 2 13, in conjunction with rotating plate 12, rotates to achieve the effect of moving connecting plate 11 and connecting column 10. A fixed seat 14 is fixedly connected inside the mounting base 3. The fixed seat 14 is used to fix one end of the compression spring 15 and provide support for the compression spring 15. The compression spring 15 is installed inside the mounting base 3. The function of the compression spring 15 is to generate elastic force through extension and contraction to provide clamping force. One end of the compression spring 15 is fixedly connected to the side wall of the fixed seat 14, and the other end of the compression spring 15 is fixedly connected to the side wall of the connecting column 10. The compression spring 15, in conjunction with the connecting column 10, performs extension and contraction, achieving the effect of using elastic force to drive the clamp 7 to clamp the meter head.
[0037] Working principle: When adjusting the direction, each tapered connecting sleeve 2 in the adjusting assembly has a universal ball 4 fixed on its upper surface, and adjacent universal balls 4 can rotate in the ball joint groove 5 inside adjacent tapered connecting sleeves 2. This allows multiple tapered connecting sleeves 2 to form a freely movable serpentine hinge structure through the cooperation of the universal balls 4 and the ball joint groove 5, thereby achieving free extension in any direction. At the same time, the butterfly spring 6 inside each tapered connecting sleeve 2 is located in the ball joint groove 5 and is in contact with the side wall of the universal ball 4. When the universal ball 4 rotates in the ball joint groove 5 and is adjusted to a suitable angle, the butterfly spring 6 will generate a continuous elastic force on the universal ball 4, tightly fitting the universal ball 4, effectively compensating for the gaps generated by long-term use, preventing loosening between the universal ball 4 and the ball joint groove 5, and ensuring the stability after adjustment.
[0038] When fixing the meter head, pull the clamp 7 by the handle 8. The clamp 7 drives the connecting post 10 to slide within the mounting base 3. The movement of the connecting post 10 will cause the rotating plate 13 to rotate the rotating plate 12. At the same time, the connecting post 10 compresses the compression spring 15 inside the mounting base 3. After the meter head is placed between the clamps 7, release the handle 8. The compression spring 15 will return to its original position under the action of elasticity, pushing the connecting post 10 to move in the opposite direction, thereby driving the clamp 7 to move closer to the center. The anti-slip texture 9 on the inner wall of the clamp 7 can increase the friction with the meter head, ensuring that the meter head is firmly clamped, thus achieving quick fixing of the meter head. To remove the meter head, pull the handle 8 again to separate the clamp 7.
