Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile gauge installation, especially relates to a rotating adjusting device of automobile gauge. BACKGROUND

[0002] Automobile gauges are a collection of tools used to detect and measure automobile parts, components, or systems. These tools typically include micrometers, torque wrenches, vernier calipers, pressure gauges, voltmeters, oscilloscopes, and scanners. Automobile gauges can be used to measure and confirm engine parameters, brake performance, tire pressure, chassis geometry, and other factors to ensure the safe operation and performance of a vehicle. By using appropriate automobile gauges, technicians can diagnose problems, adjust parts, and maintain vehicles to keep them in good condition.

[0003] After searching, patent publication No. CN221173193U discloses an adjustable automobile gauge device, which comprises a support bottom plate part and a rotating adjusting clamp table for clamping and fixing the parts on one side of the upper end surface of the support bottom plate part, and a movable abutting table. When inspecting automobile parts, pull the push-pull column welded on one side of the reinforcing block to pull the slider to one end of the groove seat, insert one end of the part into the clamp opening of the clamp block, and tighten the clamp bolt on the clamp block to clamp and fix one end of the part in the clamp block. Then loosen the push-pull column, and the slider resets under the action of the return spring, so that the abutting piece assists in abutting the other end of the part. After the abutting piece abuts the part more firmly by pushing the push-pull column, when the part needs to be rotated, the clamp head is rotated by the servo motor, and the abutting piece rotates with it, facilitating the rotation and adjustment of the part.

[0004] In the prior art, although certain automobile gauge installation effects can be achieved in use, the existing rotating adjusting device of the automobile gauge lacks the functions of convenient rotation and self-locking, which makes it inconvenient to adjust the angle when positioning the gauge, affecting the convenient positioning effect of the gauge. Therefore, we propose a rotating adjusting device of an automobile gauge to solve the above problems. UTILITY MODEL CONTENTS

[0005] The utility model aims at the problems in the background art and provides a rotating adjusting device of an automobile gauge.

[0006] The technical solution of this utility model is as follows: A rotation adjustment device for an automotive inspection tool, comprising a rotating plate, a ratchet I, a ratchet II, limiting posts, and a limiting plate. The rotating plate has limiting posts arranged in a square array on its surface. A ratchet I is fixed to one side of the lower middle portion of the rotating plate, and a ratchet II is fixed to the other side of the lower middle portion of the rotating plate. The ratchet I and ratchet II face opposite directions. A movable plate I and a movable plate II are inserted into both sides of the lower end of the rotating plate. The movable plate I and the movable plate II are used in conjunction with the ratchet I and ratchet II, respectively. Limiting plates are provided on both sides of the upper end of the rotating plate.

[0007] When in use, this device uses the lower handle to drive the limiting posts to rotate. Multiple limiting posts on the rotating plate surface provide positioning for irregular automotive parts. Manually rotating the third handle drives the lead screw, allowing the limiting plate to clamp and fix the workpiece on both sides. The device features convenient rotation and self-locking. To rotate, pressing either the first or second moving plate causes the rotating plate to rotate in one direction, preventing reverse rotation. Releasing the first or second moving plate causes the pawls to engage with the ratchet wheels, stopping the rotating plate at a fixed angle. This device utilizes a convenient mechanical design to achieve angular rotation of the rotating plate, facilitating the positioning of automotive parts and demonstrating high practicality.

[0008] Preferably, a fixing frame is fixed at the middle of both sides of the upper end of the rotating plate. A lead screw is threaded inside the fixing frame. One side of the lead screw is rotatably connected to one side of the limiting plate, and a handle is fixed on the other side of the lead screw.

[0009] Preferably, a second fixing frame is fixed to the upper end of the rotating plate, and a limiting rod is inserted inside the second fixing frame. The limiting rod is fixedly connected to the outer wall of one side of the limiting plate.

[0010] Preferably, the limiting post is threadedly connected to the rotating plate, and a handle is fixed to the lower end of the limiting post.

[0011] Preferably, the rotating plate has fixed seats on both sides and in the middle at its lower end, and both ratchet one and ratchet two are fixed between the fixed seats. One side of the moving plate is designed in an L-shape, and a pawl is provided on the surface opposite to ratchet one. One side of the moving plate is designed in an L-shape, and a pawl is provided on the surface opposite to ratchet two.

[0012] Preferably, a mounting base is fixed at the lower end of the rotating plate, and the first and second movable plates are inserted into the mounting base. A spring is fixed between the outer wall of one side of the rotating plate and the first and second movable plates, and the spring is in a compressed state under normal conditions.

[0013] Preferably, the lower ends of ratchet one and ratchet two are fixed with brackets, the lower ends of the brackets are fixed with bases, and the outer walls on both sides of the rotating plate are fixed with handles two.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model can utilize the design of the pawl, combined with the ratchet with a ratchet angle designed in opposite directions to achieve a bidirectional normal self-locking effect. When rotation is required, it is only necessary to separate the ratchet and pawl in the corresponding direction to rotate. With the ratchet and pawl still engaged on the other side, the rotating plate can only rotate in one direction.

[0016] Second, based on the first beneficial effect, this device can use multiple rotating columns to achieve the positioning effect on the lower surface of irregular workpieces, and with the limiting plates on both sides, it can achieve stable positioning of the overall workpiece. Furthermore, the angle of the rotating plates can be adjusted during positioning, making it convenient for operators to operate from various angles.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] Example 1

[0030] Please see Figures 1-5 As shown, this embodiment is a rotation adjustment device for an automotive inspection tool, including a rotating plate 1, a ratchet 12, a ratchet 2 13, a limiting post 9, and a limiting plate 8. The surface of the rotating plate 1 is provided with limiting posts 9 arranged in a square array. A ratchet 12 is fixed on one side of the lower middle part of the rotating plate 1, and a ratchet 2 13 is fixed on the other side of the lower middle part of the rotating plate 1. The ratchet 12 and ratchet 2 13 face opposite directions. A movable plate 18 and a movable plate 2 14 are inserted into both sides of the lower end of the rotating plate 1. The movable plate 18 and the movable plate 2 14 are used in conjunction with the ratchet 12 and the ratchet 2 13, respectively. Limiting plates 8 are provided on both sides of the upper end of the rotating plate 1.

[0031] When in use, this device can be driven by the lower handle 4 to rotate the limiting post 9. The limiting post 9, located on the surface of the rotating plate 1, provides multiple positioning points, enabling the positioning of the lower surface of irregular automotive parts. Then, manually rotating the handle 6 drives the lead screw 7 to rotate, and the limiting plate 8 can clamp the workpiece to fix it on both sides. This device has a convenient rotation and self-locking effect. When rotation is needed, pressing the moving plate 18 or the moving plate 2 14 will cause the rotating plate 1 to rotate in one direction, but not in the opposite direction. Releasing the moving plate 18 or the moving plate 2 14, under the action of the spring 20, the pawls 19 and 2 17 engage with the ratchet 12 and 2 13 respectively, allowing the rotating plate 1 to stop at a fixed angle. This device can achieve the angle rotation effect of the rotating plate 1 through convenient mechanical design, facilitating the positioning of automotive parts and has high practicality.

[0032] Example 2

[0033] Please see Figures 1-5 As shown, this embodiment, based on embodiment 1, further includes: a fixing frame 10 fixed at the middle of both sides of the upper end of the rotating plate 1; a screw rod 7 threadedly connected inside the fixing frame 10; one side of the screw rod 7 rotatably connected to one side of the limiting plate 8; and a handle 6 fixed on the other side of the screw rod 7. The handle 6 can rotate to drive the limiting plate 8 to center, and together with the limiting post 9, it displays the positioning process of the workpiece.

[0034] A second fixing frame 2 is fixed to the upper end of the rotating plate 1. A limit rod 11 is inserted inside the second fixing frame 2. The limit rod 11 is fixedly connected to the outer wall of one side of the limit plate 8. The limit rod 11 can ensure the stable and parallel centering movement of the limit plate 8.

[0035] The limiting post 9 is threadedly connected to the rotating plate 1. A handle 4 is fixed at the lower end of the limiting post 9. Rotating the handle 4 can change the height of the apex of the limiting post 9. Limiting posts 9 of different heights can fix the lower surface of irregular workpieces and ensure the parallel effect of the upper surface of the workpiece.

[0036] The rotating plate 1 has fixed seats 16 on both sides and in the middle of its lower end. Ratchet 12 and ratchet 2 13 are fixed between the fixed seats 16. One side of the movable plate 18 is designed in an L-shape and has a pawl 19 on the surface opposite to ratchet 12. One side of the movable plate 2 14 is designed in an L-shape and has a pawl 2 17 on the surface opposite to ratchet 2 13. When the ratchet and pawl are engaged, the rotating plate 1 can be kept from rotating. By using different engagements of the ratchet and pawl on different sides, different rotation effects of the rotating plate 1 can be changed.

[0037] A mounting base 15 is fixed at the lower end of the rotating plate 1. Movable plate one 18 and movable plate two 14 are inserted into the mounting base 15. A spring 20 is fixed between the outer wall of one side of the rotating plate 1 and movable plate one 18 and movable plate two 14. Under normal conditions, the spring 20 is in a compressed state, which can ensure the stable meshing relationship between the pawl and the ratchet. Pressing the spring 20 inward will separate the ratchet and pawl on the corresponding surface. After separation, the rotating plate 1 can be driven to rotate.

[0038] Ratchet 12 and ratchet 23 are fixed with brackets 3 at their lower ends, and bases are fixed with the lower ends of brackets 3. Handles 25 are fixed with the outer walls on both sides of the rotating plate 1. The stability of the device can be increased by using brackets 3 and bases.
