Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts, specifically a base frame. Background Technology

[0002] The car's base serves as a support point. Because the car's base protects the chassis from unnecessary damage and ensures the stability of the bracket, it is a type of automotive component. For ease of use, the base is typically placed on a frame for subsequent assembly.

[0003] However, the above-mentioned device still has the following problems during implementation:

[0004] The car base frame mainly serves to support the base. It consists of a frame and four legs. During car assembly, the frame and base are moved to the corresponding position for assembly. However, considering the terrain, in some uneven areas, it is difficult for the four legs to make full contact with the ground, which will reduce the overall stability of the frame and may even cause it to tip over in severe cases.

[0005] To address this issue, we propose a base frame. Utility Model Content

[0006] The purpose of this utility model is to provide a base frame to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A base frame includes a frame and four legs. The legs are fixedly installed at the bottom of the frame. Side plates are provided on both sides of the frame. A linkage plate is provided at the bottom of the side plate. A support rod is fixedly connected to the bottom of the linkage plate. A support sleeve is slidably connected to the surface of the support rod. Several claws are fixedly connected to the circumferential side of the support sleeve. A transmission frame is fixedly connected to the top of the side plate. Two guide rails are fixedly connected to the bottom of the frame. Two moving blocks are fixedly connected to the side of the side plate near the guide rails. A guide groove for cooperating with the guide rails is opened on one side of the moving blocks.

[0009] A transmission mechanism, which is fixedly mounted on the linkage plate, is capable of adjusting the height of the chuck;

[0010] A positioning mechanism is fixedly mounted on a guide rail and can adjust the position of the jaws.

[0011] Preferably, the transmission mechanism includes a transmission rod fixedly connected to the top of the linkage plate, the top of the transmission rod extending through to the top of the side plate and fixedly connected to a connecting block, a threaded rod threadedly connected to the top of the transmission frame, a bearing provided at the bottom of the threaded rod and rotatably connected to the top of the connecting block via a rotating shaft, and a threaded hole for cooperating with the threaded rod on the top of the transmission frame.

[0012] Preferably, the positioning mechanism includes a housing fixedly connected to the bottom of the movable block. The bottom of the frame is provided with two pull plates, and the top of the pull plates is fixedly connected with two traction rods. The two traction rods pass through the interior of the two housings respectively and are fixedly connected to a movable block. The top of the movable block is fixedly connected with a positioning rod, and the top of the positioning rod passes through the interior of the guide groove. The bottom of the guide rail is provided with a plurality of positioning holes that cooperate with the positioning rods.

[0013] Preferably, a return spring is sleeved on the surface of the traction rod, the top of the return spring is fixedly connected to the bottom of the movable block, and the bottom of the return spring is fixedly connected to the inner wall of the housing.

[0014] Preferably, a screwing block is fixedly connected to the top of the threaded rod, and screwing grooves are symmetrically formed on the circumferential side of the screwing block.

[0016] Preferably, a buffer spring is fixedly connected to the inner wall of the support sleeve, and the top of the buffer spring is fixedly connected to the bottom of the support rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, by setting up a transmission mechanism, enables the frame to rotate when it is in an uneven terrain. By rotating the turning block, the turning block drives the threaded rod to rotate in the threaded hole. The threaded rod will gradually move downward as restricted by the threaded hole, simultaneously pushing the bearing and connecting block downward. The transmission rod and linkage plate will move downward synchronously with the connecting block. The support rod and support sleeve at the bottom of the linkage plate will also move downward until the claws on the surface of the support sleeve contact the ground, achieving an auxiliary support function and thus effectively improving the stability of the frame.

[0019] 2. This utility model, by setting a positioning mechanism, enables the traction rod and movable block to move downwards when the position of the chuck is insufficient for support. By pulling down the pull plate, the traction rod and movable block move downwards simultaneously, causing the positioning rod to leave the positioning hole and disengage from the restriction on the movable block. From the side, the position of the movable block and side plate can be adjusted along the guide rail. Once the appropriate position is reached, the pull plate is released, and the elastic force generated by the return spring will cause the movable block and positioning rod to move upwards, allowing the positioning rod to enter the corresponding positioning hole, thus restricting the movable block and adjusting the position of the chuck, thereby improving the stability of the chuck support.

[0028] 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.

[0029] Please see Figure 1 - Figure 7 This utility model provides a technical solution:

[0030] Example 1:

[0031] A base frame includes a frame 1 and four support legs 2. The support legs 2 are fixedly installed at the bottom of the frame 1. Side plates 3 are provided on both sides of the frame 1. A linkage plate 4 is provided at the bottom of the side plate 3. A support rod 5 is fixedly connected to the bottom of the linkage plate 4. A support sleeve 6 is slidably connected to the surface of the support rod 5. Several claws 7 are fixedly connected to the circumferential side of the support sleeve 6. A transmission frame 8 is fixedly connected to the top of the side plate 3. Two guide rails 9 are fixedly connected to the bottom of the frame 1. Two moving blocks 10 are fixedly connected to the side of the side plate 3 near the guide rails 9. A guide groove 11 that cooperates with the guide rails 9 is opened on one side of the moving block 10.

[0032] The transmission mechanism is fixedly mounted on the linkage plate 4 and can adjust the height of the chuck 7.

[0033] The positioning mechanism is fixedly mounted on the guide rail 9 and can adjust the position of the chuck 7.

[0034] The transmission mechanism includes a transmission rod 12 fixedly connected to the top of the linkage plate 4. The top of the transmission rod 12 extends through to the top of the side plate 3 and is fixedly connected to a connecting block 13. The top of the transmission frame 8 is threadedly connected to a threaded rod 14. The bottom of the threaded rod 14 is provided with a bearing 15 and is rotatably connected to the top of the connecting block 13 through a rotating shaft. The top of the transmission frame 8 is provided with a threaded hole 16 that cooperates with the threaded rod 14.

[0035] In this embodiment, considering the terrain, in some uneven areas, it is difficult for the four legs 2 to fully contact the ground, which will cause a decrease in the overall stability of the frame 1. Therefore, by setting a transmission mechanism, when the frame 1 is in uneven terrain, by rotating the turning block 24, the turning block 24 drives the threaded rod 14 to rotate in the threaded hole 16. The threaded rod 14 will gradually move downward as restricted by the threaded hole 16, and at the same time push the bearing 15 and the connecting block 13 to move downward. The transmission rod 12 and the linkage plate 4 will move downward in sync with the connecting block 13. The support rod 5 and the support sleeve 6 at the bottom of the linkage plate 4 will also move downward until the claw 7 on the surface of the support sleeve 6 contacts the ground, achieving the function of auxiliary support, thereby effectively improving the stability of the frame 1.

[0036] A screwing block 24 is fixedly connected to the top of the threaded rod 14, and screwing grooves 25 are symmetrically opened on the circumferential side of the screwing block 24.

[0037] In this embodiment, by setting a twisting block 24 and a twisting groove 25, when it is necessary to rotate the threaded rod 14, one can place their finger inside the twisting groove 25 to grasp the twisting block 24, and then easily rotate the threaded rod 14, providing a gripping leverage point for rotating the threaded rod 14.

[0038] Limiting blocks 26 are fixedly connected to both sides of the connecting block 13, and the inner wall of the transmission frame 8 is provided with a limiting groove 27 that cooperates with the limiting block 26.

[0039] In this embodiment, by setting the limiting block 26 and the limiting groove 27, when the threaded rod 14 transmits power to the connecting block 13 and other structures, it can be restricted to move only along the trajectory of the limiting block 26 and the limiting groove 27, thereby limiting the movement trajectory.

[0040] A buffer spring 28 is fixedly connected to the inner wall of the support sleeve 6, and the top of the buffer spring 28 is fixedly connected to the bottom of the support rod 5.

[0041] In this embodiment, by setting a buffer spring 28, the elastic force generated by the buffer spring 28 can buffer the overall structure of the frame 1 when the frame 1 vibrates.

[0042] Example 2:

[0043] Based on Embodiment 1, in this embodiment, the transmission mechanism improves the stability of the frame 1 by making the adjusting claw 7 contact the ground. However, considering that the claw 7 does not have the function of position adjustment, if the position of the claw 7 is not sufficient for support, it will also lead to a decrease in the overall stability of the frame 1. In this application, the positioning mechanism includes a housing 17 fixedly connected to the bottom of the moving block 10. The bottom of the frame 1 is provided with two pull plates 18. The top of the pull plates 18 is fixedly connected with two traction rods 19. The two traction rods 19 pass through the interior of the two housings 17 respectively and are fixedly connected with a movable block 20. The top of the movable block 20 is fixedly connected with a positioning rod 21. The top of the positioning rod 21 passes through the interior of the guide groove 11. The bottom of the guide rail 9 is provided with several positioning holes 22 that cooperate with the positioning rod 21.

[0044] In this embodiment, by setting a positioning mechanism, when the position of the chuck 7 is insufficient for support, the pull plate 18 is pulled down, which drives the traction rod 19 and the movable block 20 to move downward. The positioning rod 21 will move downward synchronously with the movable block 20, so that the positioning rod 21 leaves the interior of the positioning hole 22, thereby releasing the restriction on the movable block 10. From the side, the position of the movable block 10 and the side plate 3 can be adjusted along the trajectory of the guide rail 9. After reaching the appropriate position, the pull plate 18 is released, and the elastic force generated by the return spring 23 will drive the movable block 20 and the positioning rod 21 to move upward, so that the positioning rod 21 enters the interior of the corresponding positioning hole 22, thus completing the restriction on the movable block 10 and thereby completing the adjustment of the position of the chuck 7, improving the stability of the chuck 7 support.

[0045] A return spring 23 is fitted on the surface of the traction rod 19. The top of the return spring 23 is fixedly connected to the bottom of the movable block 20, and the bottom of the return spring 23 is fixedly connected to the inner wall of the housing 17.

[0046] In this embodiment, by setting a reset spring 23, when the pull plate 18 is released, the elastic force generated by the reset spring 23 pushes the movable block 20 and the positioning rod 21 to move upward, thus achieving the function of resetting.

[0047] Working principle: When the frame 1 is in an uneven terrain, by rotating the screwing block 24, the screwing block 24 drives the threaded rod 14 to rotate in the threaded hole 16. The threaded rod 14 will gradually move downward as restricted by the threaded hole 16, and at the same time push the bearing 15 and the connecting block 13 to move downward. The transmission rod 12 and the linkage plate 4 will move downward in sync with the connecting block 13. The support rod 5 and the support sleeve 6 at the bottom of the linkage plate 4 will also move downward until the claw 7 on the surface of the support sleeve 6 contacts the ground, achieving the function of auxiliary support, thereby effectively improving the stability of the frame 1.

[0048] When the position of the chuck 7 is insufficient for support, pulling down the pull plate 18 causes the traction rod 19 and the movable block 20 to move downwards. The positioning rod 21 moves downwards synchronously with the movable block 20, causing the positioning rod 21 to leave the interior of the positioning hole 22 and releasing the restriction on the movable block 10. From the side, the position of the movable block 10 and the side plate 3 can be adjusted along the trajectory of the guide rail 9. After reaching the appropriate position, the pull plate 18 is released, and the elastic force generated by the return spring 23 causes the movable block 20 and the positioning rod 21 to move upwards, causing the positioning rod 21 to enter the interior of the corresponding positioning hole 22, thus completing the restriction on the movable block 10 and adjusting the position of the chuck 7, thereby improving the stability of the chuck 7 support.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
