Description

Technical Field

[0001] This utility model provides a device fastener, and particularly relates to a fastener for a vehicle jack balance tilt angle alarm device. Background Technology

[0002] The tilt angle alarm device for car jacking machines is a key component ensuring the safe operation of the machine. It monitors the tilt angle during operation in real time and issues an alarm when the tilt angle exceeds the safe range, preventing accidents caused by tilting and imbalance. Traditional tilt angle alarm devices typically use fixed or simple adjustable fasteners, whose basic function is to fix the alarm device in a corresponding position on the car jacking machine. However, these devices suffer from limited angle adjustment range, poor adaptability, and insufficient structural stability, making it difficult to meet the installation requirements of different alarm device specifications under complex working conditions.

[0003] Existing alarm device fasteners generally consist of simple brackets and fixing bolts, which directly fix the alarm device to the jacking machine. This structure lacks an effective angle adjustment mechanism and cannot be flexibly adjusted according to the actual installation environment and monitoring needs. Although some improved structures have added angle adjustment functions, the adjustment method is singular and the locking is unreliable, making them prone to loosening under long-term vibration or stress. At the same time, existing structures are mostly linear or quadrilateral connections, which have poor stability and cannot cope with the vibration and impact generated during jacking machine operation, resulting in unstable installation of the alarm device, affecting monitoring accuracy and service life. Utility Model Content

[0004] To address the aforementioned issues, this application provides a fastener for a vehicle jack tilt alarm device, which solves problems such as inconvenient angle adjustment, poor adaptability, and structural instability. It enables multi-directional flexible adjustment and reliable locking, improving installation stability and monitoring accuracy.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fastener for a vehicle jack tilt angle alarm device, comprising a triangular connecting frame, wherein adjusting fasteners and clamping rods are connected to the two sides of the connecting frame respectively.

[0006] The adjusting fastener includes an adapter locking ring that is connected to the connecting frame, and an adjusting locking ring is movably connected above the adapter locking ring.

[0007] The adjusting locking ring is penetrated by the clamping rod.

[0008] Preferably, the connecting frame has a through mounting hole on one corner away from the adjusting fastener, and the mounting hole has bolt mounting holes corresponding to the vehicle-mounting machine associated components, for fixed installation on the vehicle-mounting machine associated components.

[0009] Preferably, the adapter locking ring and the connecting frame are provided with fixing bolts for the hardware, and both the adjusting locking ring and the adapter locking ring are provided with a pair of locking bolts.

[0010] Preferably, the adjusting locking ring is provided with an adjusting bolt that passes through itself and is inserted into the matching locking ring. The adjusting bolt adjusts the degree of locking between the adjusting locking ring and the matching locking ring.

[0011] Preferably, the adjusting bolt is fitted with a retaining ring structure, and the retaining ring structure is also provided with a locking bolt that passes through itself.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0013] When using this device, first, fix it to the related components of the jacking machine through the mounting holes and bolt mounting holes on the connecting frame to complete the basic installation. Next, according to the specific specifications and installation requirements of the alarm device, operate the adjusting fasteners: loosen the adjusting bolt to allow the adjusting locking ring to rotate relative to the matching locking ring, adjust to the appropriate angle, and then tighten the adjusting bolt to lock the angle. At the same time, use the locking bolts on the adjusting locking ring and the matching locking ring to further reinforce it. Then, through the through-structure of the clamping rod in the adjusting locking ring, adjust the position of the clamping rod to match the alarm device and achieve stable clamping of the alarm device. The connecting bolts between the matching locking ring and the connecting frame ensure a stable connection. The retaining ring structure on the outside of the adjusting bolt and the corresponding locking bolt further enhance the reliability of the structure. Finally, through the stable structure of the triangular connecting frame and the synergistic effect of each adjusting component, the jacking machine balance tilt alarm device can be flexibly installed and reliably fixed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1 and Figure 2 As shown, a fastener for a vehicle jack tilt alarm device includes a triangular connecting frame 1, with adjusting fasteners 2 and clamping rods 3 connected to its two sides respectively. The adjusting fastener 2 has an adapter locking ring 4 that is adapted to connect with the connecting frame 1. An adjusting locking ring 5 is movably connected above the adapter locking ring 4, and the adjusting locking ring 5 is penetrated by the clamping rod 3. The connecting frame 1 has a through-hole 6 at one corner away from the adjusting fastener 2. The through-hole 6 has bolt mounting holes 7 corresponding to the components associated with the vehicle jack for fixing. The adapter locking ring 4 and the connecting frame 1 have fixing bolts 8 at corresponding positions. Both the adjusting locking ring 5 and the adapter locking ring 4 have a pair of locking bolts 9. The adjusting locking ring 5 has an adjusting bolt 10 that penetrates itself and extends into the adapter locking ring 4 for adjusting the degree of locking between the two. The adjusting bolt 10 is fitted with a retaining ring structure 11, and the retaining ring structure 11 also has a through-hole locking bolt 9.

[0025] In this implementation scheme, the triangular connecting frame 1 serves as the basic support structure. Its geometry provides higher stability than traditional linear or quadrilateral structures, effectively resisting vibrations and impacts generated during the operation of the vehicle jacking machine. The fixed connection with the vehicle jacking machine's associated components via mounting holes 6 and bolt mounting holes 7 ensures the basic positioning accuracy of the entire device. In the adjusting fastener 2, the adapter locking ring 4 is rigidly connected to the connecting frame 1 via fixing bolts 8. The movable connection design of the adjusting locking ring 5 on the adapter locking ring 4, combined with the tightness adjustment function of the adjusting bolt 10 and double-locking via the locking bolt 9, effectively solves the problems of inconvenient angle adjustment and unreliable locking in existing technologies. The clamping rod 3, through the structural design of the adjusting locking ring 5, allows the clamping rod 3 to slide axially and be fixed by the locking bolt 9. This allows for flexible adjustment of the clamping position according to the size and installation requirements of different alarm devices, significantly improving the adaptability of the device. In addition, the retaining ring structure 11 and the corresponding locking bolt 9 fitted on the outside of the adjusting bolt 10 further enhance the stability of the adjusting mechanism, prevent loosening caused by vibration during long-term use, and ensure that the alarm device always maintains an accurate monitoring position, thereby improving the reliability and service life of the entire car jack balance tilt angle monitoring system.

[0026] like Figure 3 and Figure 4 As shown, a fastener for a vehicle jack tilt alarm device uses a triangular connecting frame 1 to construct a basic support. Adjustable fasteners 2 and clamping rods 3 work together on both sides. The adjustable fasteners 2 utilize the movable connection of the adapter locking ring 4 and the adjusting locking ring 5, with the clamping rod 3 passing through the adjusting locking ring 5 to achieve angle adjustment and adaptation. The connecting frame 1 is fixed by connecting the vehicle jack components with mounting holes 6 and bolt mounting holes 7. The adapter locking ring 4 and the connecting frame 1 are connected by fixing bolts 8, and the adjusting locking ring 5 and the adapter locking ring 4 are secured by locking bolts 9 to ensure connection stability. Adjusting bolts 10 adjust the tightness of the adjusting locking ring 5 and the adapter locking ring 4. An external retaining ring structure 11 and locking bolts 9 provide auxiliary reinforcement. Through the functional linkage of each component, the device's assembly, angle adjustment, and stable fastening requirements are met.

[0027] In this implementation scheme, the triangular connecting frame 1 is made of high-strength stainless steel. After laser cutting, it is welded using argon arc welding to ensure structural strength. Utilizing the mounting holes 6 and bolt mounting holes 7 located at the corner furthest from the adjusting fastener 2, and in conjunction with the corresponding threaded holes pre-drilled on the existing car-mounting machine mounting bracket, an electric torque wrench is used to securely install the connecting frame 1 in a suitable position on the car-mounting machine using high-strength hexagonal bolts according to standard installation torque parameters, ensuring that the horizontal and vertical alignment meets the equipment installation requirements. The adapter locking ring 4 in the adjusting fastener 2 is pre-tightened to the connecting frame 1 using fixing bolts 8. A diagonal tightening method is used to ensure uniform force distribution. The adjusting locking ring 5 is fitted above the adapter locking ring 4. The frictional resistance between the two is controlled by rotating the adjusting bolt 10. An angle measuring instrument is used to monitor the rotation angle of the adjusting locking ring 5 in real time. After reaching the required angle, an Allen wrench is used to sequentially tighten the pair of locking bolts 9 on the adjusting locking ring 5 and the adapter locking ring 4, and the tightening force is verified using a torque testing device. The clamping rod 3 is made of aerospace-grade aluminum alloy and precision-machined by a CNC lathe. It passes through the hole in the adjusting locking ring 5. Based on the T-slot or bolt hole on the back of the existing car-lifting machine's balance tilt alarm device, the extension length of the clamping rod 3 is slidably adjusted. A vernier caliper is used to measure the adjustment distance to ensure accurate clamping. Then, the locking bolt 9 at the end of the clamping rod 3 is tightened to complete the fixation. The retaining ring structure 11 sleeved on the outside of the adjusting bolt 10 is installed in place using existing retaining ring pliers, and then the corresponding locking bolt 9 is tightened using a Phillips screwdriver to further reinforce the adjustment structure. Throughout the installation and adjustment process, referring to the car-lifting machine's operation manual, the existing level is used to calibrate the installation posture of the alarm device in real time, ensuring the alarm device is in the optimal monitoring position. This effectively improves the accuracy and reliability of the car-lifting machine's balance tilt monitoring system, and all component connections meet industrial-grade standards for anti-loosening, rust prevention, and vibration resistance.

[0028] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
