Description

Technical Field

[0001] The utility model relates to the field of trailer hooks, in particular to a trailer hook which is easy to install and disassemble. Background Art

[0002] Cars play an important role in modern society. With the continuous advancement of technology, the performance and safety of cars will continue to improve, making greater contributions to people's travel and environmental protection.

[0003] As an important tool for automobiles, trailer hooks are commonly found on the market and usually have a trailer hook and a threaded rod. When used, the end of the trailer hook with the threaded rod needs to be screwed into the trailer hook mounting seat inside the car to achieve towing operations, which has the advantage of low cost.

[0004] However, this common trailer hook has certain disadvantages. During use, it often needs to be screwed multiple times to be securely installed, which is time-consuming and labor-intensive, and extremely inconvenient in installation and removal. Therefore, we propose a trailer hook that is easy to install and disassemble. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a trailer hook that is easy to install and disassemble, so as to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a trailer hook that is easy to install and disassemble, comprising a trailer hook body, a connecting block fixedly installed on the end of the trailer hook body, a mounting rod slidably installed on the outer wall of the connecting block, and a slider slidably installed inside the mounting rod, a mounting block fixedly installed on the end of the slider, and a limiting block fixedly installed on the outer wall of the mounting block, a connecting rod fixedly installed on the end of the connecting block, and an extrusion ball fixedly installed on the end of the connecting rod, a first sliding groove and a second sliding groove corresponding to the connecting block and the slider are provided inside the mounting rod, a through groove for the connecting rod to slide is provided inside the mounting block and the mounting rod, a plurality of groups of telescopic rods are symmetrically arranged inside the mounting block, and a tension spring is provided on the outer wall of the telescopic rod.

[0007] By adopting the above technical solution, the mounting rod and the mounting base can be conveniently installed by only a very small number of turns during installation, which greatly saves installation time and energy.

[0008] Furthermore, the mounting rod is cylindrical in design, and a thread is provided on the outer wall of the end of the mounting rod away from the trailer hook body, and the length of the thread on the outer wall of the mounting rod is less than the length of the mounting rod.

[0009] By adopting the above technical solution, during installation, it is only necessary to align the mounting block with the mounting hole, insert the block, and screw the trailer hook body a few times. Under the action of traction, the squeezing of the mounting block by the squeezing ball and the engagement of the limit block can ensure that the trailer hook remains stable during the towing process and will not loosen or fall off. Stable installation can be achieved without the need for tedious operations and excessive number of screwing turns, which greatly saves installation time and energy. When disassembling, the trailer hook body can be easily disassembled by manually pressing the trailer hook body and screwing it a few times in the opposite direction. The operation is simple and easy to understand, which facilitates users to quickly disassemble the trailer hook in different scenarios. It not only improves the user experience, but also makes the use of the trailer hook more flexible. Whether in emergency rescue or daily use, it can be quickly installed and disassembled to meet the actual needs of users.

[0010] Furthermore, the connecting block is designed to be T-shaped as a whole, and the length of the connecting block is smaller than the length of the mounting rod.

[0011] By adopting the above technical solution, the mounting rod can be driven to rotate through the connecting block by rotating the trailer hook body, and sufficient sliding space for the connecting block in the mounting rod is ensured to pull the squeezing ball to squeeze the mounting block.

[0012] Furthermore, the mounting block is designed to be semi-cylindrical as a whole, and two groups of mounting blocks are symmetrically arranged, and the outer diameter of the two groups of mounting blocks combined is smaller than the outer diameter of the mounting rod.

[0013] By adopting the above technical solution, the mounting block can be smoothly inserted into the mounting seat when it is normally in a closed state, and will only open when the ball is squeezed, thereby ensuring the convenience of installation.

[0014] Furthermore, the limit blocks are arranged in multiple groups at equal intervals, and the height of the limit blocks is equal to the distance between the outer wall of the mounting rod and the outer wall of the mounting block, and the outer walls on both sides of the limit blocks away from the mounting block are designed with inclined surfaces.

[0015] By adopting the above technical solution, when the mounting block is squeezed and opened, the limiting block is driven to engage smoothly with the inside of the mounting seat, thereby achieving convenient and stable installation of the trailer hook body.

[0016] Furthermore, the cross section of the slider is T-shaped, and the sliding range of the slider inside the mounting rod is equal to the distance between the outer wall of the mounting rod and the outer wall of the mounting block, and the sliding range of the connecting block corresponds to the slider.

[0017] By adopting the above technical solution, the slider will not change its angle in the mounting rod, and the limit block will fully engage with the inside of the mounting seat when the mounting block is in the open state, thereby enhancing the stability of the installation.

[0018] Furthermore, the length of the connecting rod is greater than the distance from the end of the connecting block to the end of the mounting block, and the diameter of the extrusion ball is greater than the sliding range of the two groups of mounting blocks.

[0019] By adopting the above technical solution, the connecting rod has enough sliding space to realize the squeezing and releasing of the squeezing ball on the mounting block, and it is convenient for the user to squeeze out the squeezing ball, thereby facilitating disassembly.

[0020] Furthermore, one end of the tension spring is connected to the interior of one group of mounting blocks, and the other end of the tension spring is connected to the interior of another group of mounting blocks.

[0021] By adopting the above technical solution, after the restriction of the squeezing ball is released, the tension spring can reset the mounting block to a closed state, thereby achieving removal from the mounting seat.

[0022] In summary, the present invention has the following beneficial effects:

[0023] The utility model is provided with a connecting block, a connecting rod, an extruding ball, a mounting rod, a first slide groove, a second slide groove, a mounting block, a limiting block, a sliding block, a telescopic rod, a tension spring and a through groove, so that when installing, it is only necessary to align the mounting block with the mounting hole and insert it into the trailer hook body and screw it a few turns. Under the action of traction, the extruding ball squeezes the mounting block and the limiting block engages, which can ensure that the trailer hook remains stable during the towing process and will not loosen or fall off, so that a stable installation can be achieved without tedious operation and excessive number of screwing turns, which greatly saves installation time and energy. When disassembling, the disassembly can be easily completed by manually pressing the trailer hook body and screwing it a few turns in the opposite direction. The operation is simple and easy to understand, which is convenient for users to quickly disassemble the trailer hook in different scenarios, which not only improves the user experience, but also makes the use of the trailer hook more flexible. Whether in emergency rescue or daily use, it can be quickly installed and disassembled to meet the actual needs of users. BRIEF DESCRIPTION OF THE DRAWINGS

Under the action of traction, the squeezing of the mounting block 3 by the squeezing ball 103 and the engagement of the limit block 301 can ensure that the trailer hook remains stable during the towing process without loosening or falling off. A stable installation can be achieved without complicated operations and excessive number of screwing turns, which greatly saves installation time and energy. When disassembling, manually press the trailer hook body 1 and screw it a few turns in the opposite direction to easily complete the disassembly. The operation is simple and easy to understand, which is convenient for users to quickly disassemble the trailer hook in different scenarios. It not only improves the user experience, but also makes the use of the trailer hook more flexible. Whether in emergency rescue or daily use, it can be quickly installed and disassembled to meet the actual needs of users.

[0036] See also Figure 1 - Figure 8 The mounting rod 2 is cylindrical in design, and a thread is provided on the outer wall of the end of the mounting rod 2 away from the trailer hook body 1, and the length of the thread on the outer wall of the mounting rod 2 is less than the length of the mounting rod 2, so that the mounting rod 2 and the mounting seat can be easily installed by only a very small number of turns during installation, which greatly saves installation time and effort.

[0037] See also Figure 4 and Figure 5 The connecting block 101 is designed in a T-shape as a whole, and the length of the connecting block 101 is less than the length of the mounting rod 2, so that the mounting rod 2 can be driven to rotate through the connecting block 101 by rotating the trailer hook body 1, and ensure that the connecting block 101 has sufficient sliding space in the mounting rod 2 to pull the squeezing ball 103 to squeeze the mounting block 3.

[0038] See also Figure 1 - Figure 7 The mounting block 3 is designed as a semi-cylindrical shape as a whole, and there are two groups of mounting blocks 3 symmetrically arranged, and the outer diameter of the two groups of mounting blocks 3 combined is smaller than the outer diameter of the mounting rod 2, so that the mounting block 3 can be smoothly inserted into the mounting seat when it is normally in a closed state, and will only open when squeezed by the ball 103, ensuring the convenience of installation.

[0039] See also Figure 1 - Figure 7 There are multiple groups of limit blocks 301 with equal intervals, and the height of the limit blocks 301 is equal to the distance between the outer wall of the mounting rod 2 and the outer wall of the mounting block 3, and the outer walls on both sides of the limit blocks 301 away from the mounting block 3 are designed with inclined surfaces, so that when the mounting block 3 is squeezed and opened, the limit blocks 301 are driven to engage smoothly with the inside of the mounting seat, thereby realizing convenient and stable installation of the trailer hook body 1.

[0040] See also Figure 4 - Figure 7 The cross-section of the slider 302 is T-shaped, and the sliding range of the slider 302 inside the mounting rod 2 is equal to the distance between the outer wall of the mounting rod 2 and the outer wall of the mounting block 3, and the sliding range of the connecting block 101 corresponds to the slider 302, so that the slider 302 will not change its angle inside the mounting rod 2, and the limit block 301 will fully engage with the inside of the mounting seat when the mounting block 3 is opened, thereby enhancing the stability of the installation.

[0041] See also Figure 1 - Figure 8 The length of the connecting rod 102 is greater than the distance from the end of the connecting block 101 to the end of the mounting block 3, so that the connecting rod 102 has sufficient sliding space to realize the squeezing and releasing of the squeezing ball 103 on the mounting block 3. The diameter of the squeezing ball 103 is greater than the sliding range of the two groups of mounting blocks 3, so that the squeezing ball 103 can not only squeeze the mounting block 3, but also make it convenient for the user to squeeze the squeezing ball 103 out, thereby facilitating disassembly.

[0042] See also Figure 7 One end of the tension spring 304 is connected to the inside of one group of mounting blocks 3, and the other end of the tension spring 304 is connected to the inside of another group of mounting blocks 3, so that after the restriction of the squeezing ball 103 is released, the tension spring 304 can reset the mounting block 3 to a closed state, thereby realizing removal from the mounting seat.

[0043] The working principle of the present utility model is as follows: when it is necessary to use the device, first align the mounting block 3 with the mounting hole of the automobile trailer hook and insert it until the end of the mounting rod 2 conflicts with the internal thread of the automobile trailer hook mounting seat, then screw the trailer hook body 1 two turns, at this time the connecting block 101 will drive the mounting rod 2 to be threadedly connected with the mounting seat, and then, when the towing vehicle pulls the trailer hook body 1, the trailer hook body 1 is subjected to tension, which will drive the connecting block 101 and the connecting rod 102 to slide in the mounting rod 2, and the connecting rod 102 will then drive the squeezing ball 103 to move toward one end of the mounting block 3, so that the two groups of mounting blocks 3 will be squeezed to slide in the direction away from the connecting rod 102, and the limit block 301 on the outer wall of the mounting block 3 will engage with the corresponding limit block 301 in the mounting seat, thereby achieving convenient and stable installation of the trailer hook body 1;

[0044] When it is necessary to disassemble the device, the trailer hook body 1 must first be manually pressed toward the mounting seat to allow the squeezing ball 103 to disengage from the position between the two sets of mounting blocks 3. This releases the squeezing of the mounting blocks 3, and the mounting blocks 3 slide closed toward the middle position under the tension of the internal tension spring 304. At this time, the limit block 301 is separated from the mounting seat, and then the trailer hook body 1 is manually rotated two turns in the opposite direction to release the restriction of the mounting rod 2. Finally, the trailer hook body 1 can be taken out, thereby realizing convenient disassembly of the trailer hook body 1.
