Description

Technical Field

[0001] The present application relates to the technical field of automotive fuel, and specifically relates to an inspection tool for an automotive fuel tank. Background Art

[0002] The fuel tank is also called an oil tank. The inspection tools for fuel tanks are divided into two types. One is for the upper half of the fuel tank, and the other is for the lower half of the fuel tank. Since the internal structures of the upper and lower parts are different, different inspection tool bodies are used. However, the basic principle is the same. It is necessary to use a lifting tool to place the fuel tank to be tested on the inspection tool, and then use the inspection tool to detect the internal structure of the fuel tank.

[0003] According to the Chinese Patent Network (Publication No.: CN210893696U), an inspection tool for an automotive fuel tank is disclosed. By setting buffer pads, the device can elastically support the fuel tank in the placed state, and by applying a downward force to the fuel tank, the top of the fuel tank is abutted against the inspection tool body, thus avoiding the problem of abrasion between the fuel tank and the inspection tool body during the placement process. In addition, by setting two guiding plates, the device can guide the fuel tank during the placement of the lifting tool, so as to guide the open end of the fuel tank to be placed on the buffer pad. Its structure is simple and the guiding effect is good.

[0004] Although this device can guide the fuel tank and avoid abrasion, the two guiding plates of this device are designed relatively fixedly and are not convenient to adjust. Since the sizes of automotive fuel tanks are different, this device is not convenient to guide fuel tanks of different sizes, and its practicability is not high and its adaptability is poor. In addition, when this device detects the fuel tank, it is necessary to always provide a downward force to the fuel tank in order to keep the inspection tool touching the top end inside the fuel tank, which increases the labor intensity of the staff and affects the work efficiency. Summary of the Utility Model

[0005] (I) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the present application provides an inspection tool for an automotive fuel tank, which solves the problems mentioned in the above background art.

[0007] (II) Technical Solutions

[0011] By adopting the above technical solution, according to the size of the box, the two clamping plates move towards both sides, the first spring is compressed, and the elastic force of the first spring makes the two clamping plates fit the box to guide the box.

[0012] Preferably, the guiding component further includes mounting grooves opened on both sides of the base. A fixing rod is fixedly installed inside the mounting groove. A mounting frame is slidably connected to the surface of the fixing rod. The mounting frame is slidably connected to the mounting groove. An L-shaped mounting rod is slidably connected inside the mounting frame. One end of the L-shaped mounting rod is fixedly connected to the back of the mounting plate. A second spring is fixedly installed on the surface of the fixing rod.

[0013] By adopting the above technical solution, the two mounting frames move along the fixing rod to adjust the distance between the clamping plates on the left and right sides. The second spring is compressed, and the elastic force of the second spring makes the clamping plates move towards the box to fit the box and guide it.

[0014] Preferably, a plurality of slots are opened on the surface of the L-shaped mounting rod. The L-shaped mounting rod is fixedly connected to the mounting frame through a plug rod.

One side of each fixing plate is rotatably connected to a threaded rod. The threaded rod penetrates through one side of the base and is threadedly connected to the base.

[0017] By adopting the above technical solution, rotating the threaded rod makes the fixing plate move towards the box, and thus the box can be fixed.

[0018] Preferably, silica gel pads are fixedly installed on the inner surfaces of the mounting plate, the clamping plates, the guiding plates and the fixing plates.

[0019] By adopting the above technical solution, the box is protected to prevent the box from being scratched.

[0020] (III) Beneficial Effects

[0021] This application provides an inspection tool for an automotive fuel tank. The beneficial effects are as follows:

[0022] 1. The inspection tool for the automotive fuel tank facilitates the guiding of the fuel tank body through the setting of the guiding plate. By setting the mounting plate and the clamping plates on both sides, the distance between the clamping plates on both sides can be adjusted to facilitate the guiding of fuel tank bodies of different sizes, solving the problem that the two guiding plates of the existing device are designed relatively fixedly and are not easy to adjust. Since the sizes of automotive fuel tanks vary, the device is not convenient for guiding fuel tanks of different sizes, resulting in low practicability and poor adaptability.

[0023] 2. The inspection tool for the automotive fuel tank can fix the fuel tank body above the base through the setting of the fixing component, improving the stability during detection, solving the problem that when detecting the fuel tank with the existing device, a downward acting force needs to be continuously provided to the fuel tank all the time in order to make the inspection tool always touch the top end inside the fuel tank, increasing the workload of the staff and affecting the work efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following further elaborates on this application through the drawings and embodiments.

[0030] Refer to Figures 1 to 3, an embodiment of the present application provides an inspection fixture for an automotive fuel tank, including a base 1, a box body 2, and an inspection fixture body 3. The inspection fixture body 3 is installed above the base 1, the box body 2 is arranged above the inspection fixture body 3, and guiding components 4 for facilitating the guiding of the box body 2 are installed on both sides of the box body 2. The guiding components 4 include a mounting plate 401, clamping plates 402, and guiding plates 403. The clamping plates 402 are arranged on both sides of the mounting plate 401, and the guiding plates 403 are fixedly installed above the mounting plate 401 and the clamping plates 402. A fixing component 5 for facilitating the fixing of the box body 2 is arranged on the upper surface of the base 1.

[0031] Two symmetrical limiting blocks 404 are slidably connected inside both clamping plates 402. One end of each limiting block 404 is fixedly installed with a sliding rod 405. The sliding rod 405 penetrates through one side of the clamping plate 402 and is slidably connected to the surface of the clamping plate 402. The other end of the sliding rod 405 is fixedly connected to the surface of one side of the mounting plate 401. A first spring 406 is fixedly installed on the surface of the sliding rod 405.

[0032] The guiding component 4 further includes mounting grooves 407 opened on both sides of the base 1. A fixing rod 408 is fixedly installed inside the mounting grooves 407. A mounting frame 409 is slidably connected to the surface of the fixing rod 408. The mounting frame 409 is slidably connected to the mounting grooves 407. An L-shaped mounting rod 410 is slidably connected inside the mounting frame 409. One end of the L-shaped mounting rod 410 is fixedly connected to the back of the mounting plate 401. A second spring 411 is fixedly installed on the surface of the fixing rod 408.

[0033] A plurality of slots 412 are opened on the surface of the L-shaped mounting rod 410. The L-shaped mounting rod 410 is fixedly connected to the mounting frame 409 through insertion rods.

[0034] The box body 2 is placed into the guiding plates 403 from above through a lifting tool. According to the size of the box body 2, the clamping plates 402 on both sides move towards both sides, the first spring 406 is compressed, the mounting frames 409 on both sides move along the fixing rod 408, and the second spring 411 is compressed. Subsequently, the clamping plates 402 on both sides are attached to the surface of the box body 2 through the elastic forces of the first spring 406 and the second spring 411 to guide the box body 2 until the box body 2 is buckled on the inspection fixture body 3, and then it can be inspected. This solves the problem that the two guiding plates 403 of the existing device are designed relatively fixedly and are not convenient for adjustment. Since the sizes of automotive fuel tanks are different, this device is not convenient for guiding fuel tanks of different sizes, and its practicability is not high and its adaptability is poor.

[0035] Refer to Figure 1 and Figure 4, in one aspect of the present embodiment, the fixing component 5 includes an annular groove 501 formed on the surface of the base 1. Both sides of the annular groove 501 are slidably connected with fixing plates 502. One side of the fixing plate 502 is rotatably connected with a threaded rod 503. The threaded rod 503 penetrates through one side of the base 1 and is threadedly connected with the base 1.

[0036] Silicone pads 6 are fixedly installed on the inner surfaces of the mounting plate 401, the clamping plate 402, the guiding plate 403, and the fixing plate 502.

[0037] After the box body 2 is placed in the annular groove 501, rotate the threaded rods 503 on both sides. Since the threaded rods 503 are rotatably connected with the fixing plates 502, the threaded rods 503 drive the fixing plates 502 to move towards one side of the box body 2, so as to fix the box body 2, avoiding the deviation of the box body 2 during detection. It solves the problem that in the existing device for detecting the fuel tank, a downward force needs to be continuously provided to the fuel tank all the time to make the detecting tool always touch the top inside the fuel tank, increasing the labor intensity of the staff and affecting the work efficiency.

[0038] All electrical equipment in this solution is powered by an external power supply.

[0039] Working principle: When the automotive fuel tank detecting tool is in use, the box body 2 is placed into the guiding plate 403 from above through a lifting tool. According to the size of the box body 2, the clamping plates 402 on both sides move towards both sides. The first spring 406 is compressed. The mounting frames 409 on both sides move along the fixing rods 408. The second spring 411 is compressed. Subsequently, the clamping plates 402 on both sides fit on the surface of the box body 2 through the elastic forces of the first spring 406 and the second spring 411 to guide the box body 2 until the box body 2 is buckled on the detecting tool body 3. Then rotate the threaded rods 503 on both sides to drive the fixing plates 502 to move towards one side of the box body 2, so as to fix the box body 2 and detect the inside of the box body 2.
