Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of pipeline testing devices, and in particular relates to a rapid testing device for automotive air conditioning pipelines. Background Technology
[0002] Currently, most automotive air conditioning piping systems on the market are manufactured using components such as aluminum pipes, rubber hoses, and pressure plates. The aluminum pipes and pressure plates are often joined by brazing, and the rubber hoses are usually connected by crimping. This manufacturing process can easily lead to micro-leakage in the automotive air conditioning piping, resulting in a decrease in product quality. To prevent leaks during the connection of the air conditioning piping pressure plates, a water test is required on the entire air conditioning piping assembly during production. The current mainstream method for water testing is to connect the connector of the pressure plate on the automotive air conditioning piping to the water test interface. This water testing process is cumbersome and inefficient.
[0003] For example, Chinese Patent Application No. 202021509507.7 discloses a novel rapid testing device for automotive air conditioning pipes, comprising a nut cap, a sealing tube body, a main body, a compression spring, and two handles. The main body includes a front end and a rear end connected to the front end. The front end has an inner hole one and an inner hole two communicating with the inner hole one, and the rear end has an inner hole three communicating with the inner hole two. The sealing tube body has inner holes four, five, and six communicating in sequence, and the sealing tube body is divided into a front section and a rear section. The two ends of the compression spring are respectively installed in inner holes one and six. A sealing groove two is opened on the outer wall of the rear section of the sealing tube body, and a sealing ring that can contact the wall of the inner hole four is installed in the sealing groove two. The nut cap is threadedly connected to the front end, and a through hole is opened on the nut cap, through which the front end of the sealing tube body passes. Both handles are hinged to the rear end, and a side pressure plate is provided at one end of each handle. This utility model is ingeniously designed and easy to use.
[0004] However, existing technologies have some problems: during the process of clamping and fixing the pipe, holding the open ends of the two handles causes the two handles to open, and in the process mentioned above, the two handles rotate in an arc shape. During the clamping process, the clamping ends of the two handles will move to the upper end of the pipe. Therefore, when clamping the pipe, the handles cannot achieve clamping and fixing of the pipe. When the pipe is under force, the clamping will loosen, causing the pipe to fall off. Therefore, we propose a rapid detection device for automotive air conditioning pipes. Utility Model Content
[0005] To address the problems existing in the above-mentioned technologies, this utility model provides a rapid detection device for automotive air conditioning pipes, which solves the problem that during the process of clamping the pipes, the clamping ends of the two handles will move to the upper end of the pipes, so the handles cannot clamp and fix the pipes when they are clamped, and the clamping will loosen when the pipes are under force, causing the pipes to fall off.
[0006] This utility model is implemented as follows: a rapid testing device for automotive air conditioning pipes includes a main body, a pipe, and two handles disposed on the outside of the main body. A sealing tube is connected to the front end of the main body, and a fixed sleeve is connected to the lower rear end of the main body. The two handles are arranged in a U-shape on the outside of the main body, and each handle has an arc-shaped groove at one end face where they meet. The arc-shaped groove is located at the front end of the sealing tube and contacts the sealing tube. Adjustable parts are provided at the upper and lower ends of each handle on the front side of the sealing tube, and the handles are connected to each other via the adjustable parts. A spring is provided on the side of each handle near the fixed sleeve, and the handle is connected to the fixed sleeve via the spring. A set of connecting parts is provided at the outer end of each handle, and the handle is movably connected to the fixed sleeve via the connecting parts. The pipe is located at the front end of the handle and extends into the sealing tube. A sealing ring is fixedly connected to the outer wall of the pipe, and the sealing ring contacts the handle and the outer wall of the sealing tube.
[0007] In a preferred embodiment of this utility model, the adjusting component includes symmetrically arranged fixing blocks and a sliding plate located between the fixing blocks. The fixing blocks are fixedly connected to the outer wall of the handle. Each corresponding outer wall of the fixing block is provided with an inwardly recessed tension groove. Both ends of the sliding plate extend into the tension groove. Both ends of the sliding plate located inside the tension groove are connected to limit blocks. The outer wall of the limit block is connected to a tension spring, and the other end of the tension spring is fixedly connected to the inner wall of the fixing block.
[0008] As a preferred embodiment of this invention, the outer wall of the handle is provided with a through hole.
[0009] As a preferred embodiment of this invention, the handle has multiple threaded holes on both its upper and lower end faces.
[0010] In a preferred embodiment of this invention, one end of the spring is fixedly connected to the fixed sleeve, and the other end of the spring is integrally formed with a connecting part, which extends through the through hole to the outside of the handle.
[0011] As a preferred embodiment of this utility model, a limiting sleeve is provided at one end of the connecting part located on the outside of the handle. The limiting sleeve is specifically made of a rubber material and is sleeved on the outside of the connecting part. A limiting ring is connected to the outer wall of the limiting sleeve, and the diameter of the limiting ring is larger than the diameter of the through hole.
[0012] As a preferred embodiment of this utility model, the connecting member includes movable plates disposed at the upper and lower ends of the handle. The upper end of the movable plate is provided with a movable shaft and a screw shaft. The movable shaft passes through the movable plate and the fixed sleeve. Both ends of the upper end of the movable shaft are limited by nuts. The nuts are in contact with the movable plate. The screw shaft passes through the movable plate and is threadedly connected to a threaded hole.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model allows the handle to open outwards when the open end of the handle is grasped, under the action of the connector. With the help of the adjusting component, the two handles can move in parallel relative to each other, making it easy to insert the pipe into the sealed tube body. The sealing ring contacts the sealed tube body. The elastic force of the adjusting component itself, combined with the spring, makes it easy for the handle to return to its original position, quickly clamping and fixing the pipe, preventing the pipe from loosening or falling off after clamping, thus facilitating the water inspection of the car air conditioning pipe.
[0015] 2. When the handle of this utility model is opened outward, it drives the fixing block to move. The fixing block pulls the tension spring, causing the fixing block to move on the slide plate, so that the two arc-shaped grooves open, making it easier to insert the pipe into the sealed pipe body. When it is necessary to clamp and fix the pipe, simply release the handle, the tension spring will rebound, and it can quickly drive the handle to return to its original position, thus quickly clamping and fixing the pipe.
[0016] 3. In this utility model, one end of the spring with a connecting part passes through the through hole, and the connecting part is inserted into the inside of the limiting sleeve. The limiting sleeve limits the spring, which facilitates the connection between the spring and the handle. When the handle is used, the spring resets the handle, and the handle is easy to disassemble and assemble. Attached Figure Description

[0024] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0025] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0026] Example 1:
[0027] like Figure 1 As shown in the figure, this utility model provides a rapid testing device for automotive air conditioning pipes, including a main body 3, a pipe 6, and two handles 1 disposed on the outside of the main body 3. A sealing tube 32 is connected to the front end of the main body 3, and a fixing sleeve 31 is connected to the lower rear end of the main body 3. The two handles 1 are arranged in a U-shape on the outside of the main body 3, and each handle 1 has an arc-shaped groove 13 at one end face where they meet. The arc-shaped groove 13 is located at the front end of the sealing tube 32 and contacts the sealing tube 32. Adjusting elements 2 are provided at both the upper and lower ends of the handles 1 on the front side of the sealing tube 32, and the handles 1 are connected to each other through the adjusting elements 2. A spring 33 is provided on the side of each handle 1 near the fixing sleeve 31, and the handle 1 is connected to the fixing sleeve 31 through the spring 33. Each end is equipped with a set of connectors 4. The handle 1 is movably connected to the fixed sleeve 31 through the connectors 4. The pipe 6 is located at the front end of the handle 1 and extends into the sealed tube body 32. A sealing ring 61 is fixedly connected to the outer wall of the pipe 6. The sealing ring 61 contacts the handle 1 and the outer wall of the sealed tube body 32. By holding the open end of the handle 1, the handle 1 opens outward under the action of the connectors 4. With the cooperation of the adjusting part 2, the two handles 1 move parallel to each other in opposite directions, which makes it easy to insert the pipe 6 into the sealed tube body 32. The sealing ring 61 contacts the sealed tube body 32. Through the rebound force of the adjusting part 2 itself and the spring 33, the handle 1 is easily reset, and the pipe 6 is quickly clamped and fixed, preventing the pipe 6 from loosening or falling off after clamping, thus facilitating the water inspection of the car air conditioning pipe.
[0028] like Figure 4As shown, the adjusting component 2 includes symmetrically arranged fixing blocks 21 and sliding plates 22 located between the fixing blocks 21. The fixing blocks 21 are fixedly connected to the outer wall of the handle 1. Each corresponding outer wall of the fixing blocks 21 has an inwardly recessed tension groove 211. Both ends of the sliding plates 22 extend into the tension groove 211. Both ends of the sliding plates 22 located inside the tension groove 211 are connected to limit blocks 221. The outer wall of the limit blocks 221 is connected to a tension spring 23. The other end of the tension spring 23 is fixedly connected to the inner wall of the fixing blocks 21. When the handle 1 is opened outward, it drives the fixing blocks 21 to move. The fixing blocks 21 pull the tension spring 23, causing the fixing blocks 21 to move on the sliding plates 22, so that the two arc-shaped grooves 13 open, making it easier to insert the pipe 6 into the sealed tube body 32. When it is necessary to clamp and fix the pipe 6, simply release the handle 1, and the tension spring 23 will rebound, which can quickly drive the handle 1 to return to its original position and quickly clamp and fix the pipe 6.
[0029] like Figure 2 As shown, the outer wall of the handle 1 is provided with a through hole 12; both the upper and lower end faces of the handle 1 are provided with multiple threaded holes 11. The through hole 12 facilitates the connection of the spring 33, and the threaded hole 11 facilitates the connection of the screw shaft 42.
[0030] like Figure 5 and Figure 6 As shown, one end of the spring 33 is fixedly connected to the fixed sleeve 31, and the other end of the spring 33 is integrally formed with a connecting part 331. The connecting part 331 extends through the through hole 12 to the outside of the handle 1. The end of the connecting part 331 located on the outside of the handle 1 is provided with a limiting sleeve 5. The limiting sleeve 5 is specifically made of a rubber material. The limiting sleeve 5 is sleeved on the outside of the connecting part 331. The outer wall of the limiting sleeve 5 is connected with a limiting ring 51. The diameter of the limiting ring 51 is larger than the diameter of the through hole 12. The end of the spring 33 with the connecting part 331 is passed through the through hole 12, and the connecting part 331 is inserted into the limiting sleeve 5. The limiting sleeve 5 limits the spring 33, which facilitates the connection of the spring 33 to the handle 1. When the handle 1 is used, the spring 33 can be reset, and the handle 1 can be easily disassembled and assembled.
[0031] like Figure 3 As shown, the connector 4 includes movable plates 43 disposed at the upper and lower ends of the handle 1. The upper end of the movable plate 43 is provided with a movable shaft 41 and a screw shaft 42. The movable shaft 41 passes through the movable plate 43 and the fixed sleeve 31. Both ends of the upper end of the movable shaft 41 are limited by nuts, and the nuts are in contact with the movable plate 43. The screw shaft 42 passes through the movable plate 43 and is threadedly connected to the threaded hole 11. During the use of the handle 1, the open end of the handle 1 moves inward, causing the movable plate 43 to rotate on the fixed sleeve 31, thereby causing the other end of the handle 1 to open outward, which facilitates the use of the clamping end of the handle 1 in conjunction with the adjusting component 2, realizing relatively parallel movement and facilitating the addition of pipelines.
[0032] Working principle of Example 1:
[0033] During use, when the handle 1 is in use, the open end of the handle 1 moves inward, causing the movable plate 43 to rotate on the fixed sleeve 31, thereby causing the other end of the handle 1 to open outward, inserting the pipe into the sealed tube body 32. The Shudie sealing ring 61 contacts the sealed tube body 32. Then, the handle 1 is loosened, the tension spring 23 rebounds, causing the fixed block 21 to reset. With the spring 33 rebounding, the handle 1 is reset, so that the arc groove 13 set in the handle 1 is in close contact with the pipe 6, realizing quick clamping of the pipe 6, which is convenient for water inspection of the car air conditioning pipe.
