[0018] 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.

[0019] Example Please see Figures 1-8 The present invention provides the following technical solution: A high-strength tethering device for vehicle-mounted equipment, comprising: Vehicle-mounted compartment 1; Support rod slot 2, multiple support rod slots 2 are provided, and multiple support rod slots 2 are respectively opened on the upper and lower inner walls and side inner walls of the vehicle body 1; The support assembly consists of multiple sets. Each set of the support assembly includes a support base rod 4, an adjusting support groove 5, a height adjusting sleeve 6, a bidirectional threaded groove 7, an upper threaded support rod 8, and an upper slot insertion block 9. The support base rod 4 is slidably connected to the support rod slot 2. The adjusting support groove 5 is opened on the inner circumference of the support base rod 4. The height adjusting sleeve 6 is rotatably connected to the adjusting support groove 5. The bidirectional threaded groove 7 is opened on the inner circumference of the height adjusting sleeve 6. The upper threaded support rod 8 is threadedly connected to the upper thread of the bidirectional threaded groove 7. The upper slot insertion block 9 is fixedly connected to the upper end of the upper threaded support rod 8 and slidably connected to the support rod slot 2. The expansion component is located at the lower end of the support base rod 4. It expands outward when supported by the support component to ensure the stability of the device. The lower insertion component slides downwards while supported by the supporting component, driving the outer expansion component to expand outwards.

[0020] In a specific embodiment of this utility model, multiple support rod slots 2 are provided, respectively opened on the upper inner wall, lower inner wall, and left and right side inner walls of the vehicle body 1, forming a multi-directional arrangement for inserting support components for fixation. The support base rod 4 is the basic structure of the support component. The upper threaded support rod 8 inside the support base rod 4 can extend and retract upward when rotated to insert into the support rod slot 2 for fixation. The adjusting support rotating groove 5 is used to accommodate and rotatably connect the height adjusting sleeve 6. The height adjusting sleeve 6 is rotatably connected to the inside of the support base rod 4 through the rotating groove and supports the adjusting component. The bidirectional threaded groove 7 has a structure with two sections of threads in opposite directions, used to synchronously drive the upper threaded support rod 8 and the lower threaded insertion rod 10. When the operator rotates... When the height adjustment sleeve 6 is in use, due to the structural characteristics of the bidirectional threaded groove 7, the upper threaded support rod 8 moves upward, pushing the upper slot insertion block 9 into the slot on the top of the carriage. At the same time, the lower threaded insertion rod 10 moves downward, and the outward expansion insertion rod 20 pushes the arc-shaped compressed block 14, causing the outward push slider 13 to slide outward, thereby pushing the outward expansion rubber block 12 to expand outward and fit tightly against the inner wall of the support rod slot 2, improving the stability of the device. This device forms a composite structure of vertical support and horizontal clamping, effectively enhancing the support strength and preventing the carriage from shaking or deforming. In addition, the outward expansion component is set to automatically expand outward during the support process, reducing the loosening problem caused by gaps and ensuring that the support structure fits tightly against the inner wall of the carriage.

[0021] Please refer to the details. Figures 1-8 The lower insertion assembly includes a lower threaded insertion rod 10, an outer expansion insertion rod 20, a limiting connecting groove 26, and a limiting connecting rod 27. The lower threaded insertion rod 10 is threaded into the lower end thread of the bidirectional threaded groove 7. The outer expansion insertion rod 20 is fixedly connected to the lower end of the lower threaded insertion rod 10. The limiting connecting groove 26 is opened at the upper end of the lower threaded insertion rod 10. The limiting connecting rod 27 is fixedly connected to the lower end of the upper threaded support rod 8 and slides within the limiting connecting groove 26.

[0022] In this embodiment: the lower threaded insertion rod 10 is located at the lower end of the bidirectional threaded groove 7, and the outer expansion insertion rod 20 is fixedly connected to the lower end of the lower threaded insertion rod 10. When the lower insertion assembly extends downward, it contacts the outer expansion assembly. The lower threaded insertion rod 10 and the upper threaded support rod 8 are mutually limited by the limiting connecting groove 26 and the limiting connecting rod 27. When the lower threaded insertion rod 10 cannot rotate, the upper threaded support rod 8 can only move up and down.

[0023] Please refer to the details. Figures 1-8 A limiting groove 24 is provided on the inner circumference of the supporting base rod 4, and a limiting slider 25 is fixedly connected to the outer circumference of the threaded insertion rod 10. The limiting slider 25 slides within the limiting groove 24.

[0024] In this embodiment: the limiting slide groove 24 extends axially, the limiting slider 25 is embedded in the limiting slide groove 24 and can slide freely in the axial direction therein, so as to realize the linear guiding control of the lower threaded insertion rod 10. When the height adjusting sleeve 6 is rotated, the lower threaded insertion rod 10 and the upper threaded support rod 8 can only move axially.

[0025] Please refer to the details. Figures 1-8 The expansion assembly includes an expansion groove 11, an expansion rubber block 12, an expansion slider 13, an arc-shaped compressed block 14, a sliding upper limit ring 15, and a return spring 16. The sliding upper limit ring 15 is fixedly connected to the inner circumference of the support base rod 4. The expansion groove 11 is opened in the inner circumference of the support base rod 4. The expansion rubber block 12 is slidably connected in the expansion groove 11. The expansion slider 13 is fixedly connected to one end of the expansion rubber block 12 and slides between the lower inner wall of the sliding upper limit ring 15 and the lower inner wall of the support base rod 4. The arc-shaped compressed block 14 is fixedly connected to the upper end of the expansion slider 13 and contacts the expansion insertion rod 20. The return spring 16 is fixedly connected to one end of the expansion slider 13 and one side inner wall of the support base rod 4.

[0026] In this embodiment: the expansion groove 11 is formed on the inner circumference of the support base rod 4, serving as a sliding channel for the expansion rubber block 12. The expansion rubber block 12 is slidably connected to the inside of the expansion groove 11 and is made of elastic rubber material. It is used to contact the side wall of the support rod slot 2 and provide friction. The outward push slider 13 is connected to the arc-shaped compressed block 14. When the outward expansion insertion rod 20 presses down on the arc-shaped surface of the arc-shaped compressed block 14, it converts it into a horizontal thrust, pressing the expansion rubber block 12 against the inner wall of the support rod slot 2 and compressing the return spring 16 to retract. After the outward expansion action is completed, the outward expansion rubber block 12 is driven to automatically return to its initial position, which facilitates the disassembly of the device. The sliding upper limit ring 15 is used to limit the upward sliding of the outward push slider 13. The outward expansion assembly realizes the automatic outward expansion clamping function during the support process, which enhances the support strength.

[0027] Please refer to the details. Figures 1-8 The lower inner wall of the support rod 4 is fixedly connected to a sliding lower limit ring 17, and the lower end of the push slider 13 is fixedly connected to a limit slide plate 18. The limit slide plate 18 is fixedly connected to the lower end of the push slider 13 and is blocked by the sliding lower limit ring 17 when sliding to limit the sliding distance of the push slider 13.

[0028] In this embodiment: after the support is completed, the reset spring 16 pushes the outward sliding block 13 to retract. When the limiting slide plate 18 slides to the position of the lower sliding limit ring 17, it is blocked by its structure and cannot continue to move forward, thus avoiding the risk of the outward expansion rubber block 12 falling off.

[0029] Please refer to the details. Figures 1-8 The upper end of the outwardly expanding rubber block 12 is provided with an elastic hollow extrusion groove 19, which extrudes the inner circumference of the support rod slot 2 when the outwardly expanding rubber block 12 is expanding.

[0030] In this embodiment: the outwardly expanding rubber block 12 is made of rubber material with certain hardness and good elasticity. The elastic hollow extrusion groove 19 is opened on the upper surface of the outwardly expanding rubber block 12, and has a strip arc structure. The interior is designed with a cavity, which enables it to have the ability to compress and deform, so as to better fit the irregular or inclined surface of the support rod slot 2, and significantly improve the clamping force and stability.

[0031] Please refer to the details. Figures 1-8 One end of the height adjustment sleeve 6 is rotatably connected to a rotating handle 21 via a rotating shaft. The lower end of the rotating handle 21 is fixedly connected to a pin 22. A fixing hole 23 is provided on the inner circumference of the support base rod 4. The pin 22 matches the fixing hole 23.

[0032] In this embodiment: the rotating handle 21 is rotatably connected to one end of the height adjusting sleeve 6 via a rotating shaft. When adjusting the height, the user holds the rotating handle 21 and rotates it to drive the height adjusting sleeve 6 to rotate, thereby driving the threaded support rod 8 to move up or down to adjust the support height. The pin 22 is fixedly connected to the lower end of the rotating handle 21. The pin 22 can be inserted into any fixed insertion hole 23. After the height adjustment is completed, the free rotation of the rotating handle 21 is restricted, thereby locking the position of the height adjusting sleeve 6.

[0033] Please refer to the details. Figures 1-8 The inner side wall of the multiple support rod slots 2 is provided with a preliminary stabilization slot 3, and the outer circumferential surface of the support base rod 4 is fixedly connected with a preliminary stabilization plate 28, which slides within the multiple preliminary stabilization slots 3.

[0034] In this embodiment: the preliminary stabilization slot 3 is a non-circular fixing slot. When installing the device, the preliminary stabilization plate 28 is first inserted into the preliminary stabilization slot 3. Then, the operator can step on the preliminary stabilization plate 28 to achieve preliminary fixation of the device and prevent the device from shaking during installation.

[0035] The working principle and usage process of this utility model are as follows: Multiple support rod slots 2 are provided, respectively located on the upper inner wall, lower inner wall, and left and right side inner walls of the vehicle compartment 1, forming a multi-directional arrangement for inserting support components for fixation. The support base rod 4 is the basic structure of the support component. The upper threaded support rod 8 inside the support base rod 4 can extend and retract upwards when rotated to insert into the support rod slot 2 for fixation. The adjusting support rotating groove 5 is used to accommodate and rotatably connect the height adjusting sleeve 6. The height adjusting sleeve 6 is rotatably connected to the inside of the support base rod 4 through the rotating groove and supports the adjusting component. The bidirectional threaded groove 7 has a structure with two sections of threads in opposite directions, used to synchronously drive the upper threaded support rod 8 and the lower threaded insertion rod 10. When the operator rotates... When the height adjustment sleeve 6 is rotated, due to the structural characteristics of the bidirectional threaded groove 7, the upper threaded support rod 8 moves upward, pushing the upper slot insertion block 9 into the slot on the top of the carriage. At the same time, the lower threaded insertion rod 10 moves downward, and the outward expansion insertion rod 20 pushes the arc-shaped compressed block 14, causing the outward push slider 13 to slide outward, thereby pushing the outward expansion rubber block 12 to expand outward and closely adhere to the inner wall of the support rod slot 2, improving the stability of the device. This device forms a composite structure of vertical support and horizontal clamping, effectively enhancing the support strength and preventing the carriage from shaking or deforming. In addition, the outward expansion component is set to automatically expand outward during the support process, reducing the loosening problem caused by gaps and ensuring that the support structure is tightly fitted to the inner wall of the carriage.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
