Description

Technical Field

[0001] This utility model relates to the field of oil pipe technology, and in particular to an oil pipe airtightness inspection tool. Background Technology

[0002] In an engine, oil lines are primarily sealed using sealing rings. Poor sealing of the oil lines can lead to oil leaks, which can severely impact engine performance.

[0003] The prior art CN204085807U discloses an oil pipe sealing performance testing device, including an inflation device, a container, and a gauge. After the oil pipe is fixedly connected and sealed to the gauge inside the container, the inflation device outside the container inflates it through an air pipe. In use, the container is filled with water, with the water level covering the oil pipe. The sealing performance of the oil pipe is tested by observing whether air bubbles emerge around it. Inflating the oil pipe with an inflation device and judging the sealing performance by the presence or absence of air bubbles is convenient and simple.

[0004] However, the existing device uses screws to fix the oil pipes. When multiple oil pipes need to be tested, the screws need to be repeatedly turned and removed to fix the oil pipes, which makes the test time long and thus the test efficiency low. Utility Model Content

[0005] The purpose of this utility model is to provide an oil pipe airtightness inspection tool, which aims to solve the problem that the existing device uses screws to fix the oil pipes. When multiple oil pipes need to be inspected, the screws need to be repeatedly turned and removed to fix the oil pipes, which makes the inspection time long and the inspection efficiency low.

[0006] To achieve the above objectives, this utility model provides an oil pipe airtightness inspection tool, including a worktable.

[0007] It also includes clamping components,

[0008] The clamping assembly includes a fixed frame, a support rod, a first clamp, a movable rod, a second clamp, a telescopic spring, and a fixing member. The fixed frame is fixedly connected to the worktable and located on one side of the worktable. The support rod is fixedly connected to the fixed frame and located on one side of the fixed frame. The first clamp is fixedly connected to the support rod and located on one side of the support rod. The movable rod is slidably connected to the fixed frame. The second clamp is fixedly connected to the movable rod and located on the side of the movable rod near the first clamp. The two ends of the telescopic spring are respectively connected to the fixed frame and the second clamp through the fixing member. The telescopic spring is located on the side of the fixed frame near the second clamp. The fixing member is disposed on the fixed frame and the second clamp and is connected to the telescopic spring.

[0009] The fixing component includes a first fixing seat and a second fixing seat. The first fixing seat is fixedly connected to the fixing frame and the telescopic spring, respectively, and the first fixing seat is located on the side of the fixing frame closer to the telescopic spring. The second fixing seat is fixedly connected to the second clamp and the telescopic spring, respectively, and the second fixing seat is located on the side of the second clamp closer to the telescopic spring.

[0010] The clamping assembly further includes a pull ring, which is fixedly connected to the movable rod and located on the side of the movable rod away from the second clamp.

[0011] The clamping assembly further includes a first rubber pad and a second rubber pad. The first rubber pad is fixedly connected to the first clamp and is located on one side of the first clamp. The second rubber pad is fixedly connected to the second clamp and is located on one side of the second clamp.

[0012] The fixing frame has a movable through hole, which is located on the side of the fixing frame near the movable rod and cooperates with the movable rod.

[0013] This utility model discloses an oil pipe airtightness inspection tool. When the oil pipe needs to be fixed on the worktable, the operator moves the movable rod to the right, thereby moving the second clamp to the right. At the same time, the telescopic spring is compressed and deformed under the movement of the second clamp. The operator places the oil pipe between the first clamp and the second clamp, releases the movable rod, and the compressed telescopic spring rebounds to its original position after being relieved of force. This causes the second clamp to rebound to its original position and cooperate with the first clamp to clamp and fix the oil pipe. Thus, the movement of the movable rod and the rebound of the telescopic spring can quickly fix the oil pipe to the first clamp and the second clamp support, reducing installation and disassembly time and improving the efficiency of oil pipe inspection.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the structure of the oil pipe airtightness inspection tool of this utility model. Figure 2 This is a structural schematic diagram of the fixing frame of this utility model. Figure 3 This is a schematic diagram of the clamping component of this utility model.

[0021] This utility model provides an oil pipe airtightness inspection tool, including a worktable 101 and a clamping assembly. The clamping assembly includes a fixed frame 102, a support rod 103, a first clamp 104, a movable rod 105, a second clamp 106, a telescopic spring 107, a fixing component, a pull ring 108, a first rubber pad 109, and a second rubber pad 110. The fixing component includes a first fixing seat 111 and a second fixing seat 112. The fixed frame 102 has a movable through hole. This solution solves the problem of existing devices that use screws to fix oil pipes. When multiple oil pipes need to be inspected, the screws need to be repeatedly turned and removed to fix the oil pipes, resulting in long inspection times and low inspection efficiency. This solution can be used when rapid fixing of oil pipes is required.

[0022] In this embodiment, the oil pipe is fixed on the workbench 101, and the inflation device and the pressure regulating device are connected to the oil pipe. Finally, the workbench 101 is placed in a container filled with water. The oil sealing is checked by whether bubbles emerge around the oil pipe. The structure of the inflation device, the pressure regulating device and the container is described in detail in the prior art CN204085807U, and will not be repeated here.

[0023] The fixed frame 102 is fixedly connected to the workbench 101 and located on one side of the workbench 101. The support rod 103 is fixedly connected to the fixed frame 102 and located on one side of the fixed frame 102. The first clamp 104 is fixedly connected to the support rod 103 and located on one side of the support rod 103. The movable rod 105 is slidably connected to the fixed frame 102. The second clamp 106 is fixedly connected to the movable rod 105 and located on the side of the movable rod 105 near the first clamp 104. The telescopic spring 107 is connected to the fixed frame 102 and the second clamp 106 through the fixed member. The telescopic spring 107 is located on the fixed frame 102 near the first clamp 104. Near the second clamp 106, the fixing member is disposed on the fixing frame 102 and the second clamp 106, and connected to the telescopic spring 107. There are two fixing frames 102, which are welded to the workbench 101. There are two support rods 103, which are welded to the left side of the corresponding two fixing frames 102. There are two first clamps 104, which are welded to the corresponding two support rods 103. The first clamps 104 have clamping grooves. There are two movable rods 105, which are slidably connected to the right side of the corresponding two fixing frames 102. The fixing frames 102 can control the movable rods 105. The sliding connection support is provided. There are two second clamps 106, which are welded to the corresponding two movable rods 105. The movement of the movable rods 105 can connect and support the movement of the second clamps 106. The second clamps 106 also have clamping grooves, which can cooperate with the first clamps 104 to abut and clamp the outer side of the oil pipe. There are two telescopic springs 107, and the two ends of the two telescopic springs 107 are connected to the fixed frame 102 and the second clamps 106 through the fixing member. The deformation and restoring ability of the telescopic springs 107 can drive the movement of the second clamps 106. The fixing member is set on the fixed frame 102 and the second clamps 106. The oil pipe is mounted on the clamp 106 and connected to the telescopic spring 107. The two ends of the telescopic spring 107 are fixed to the fixing frame 102 and the second clamp 106 via the fixing component. This allows the operator to move the movable rod 105 to the right when the oil pipe needs to be fixed to the worktable 101. The movement of the movable rod 105 moves the second clamp 106 to the right, and the telescopic spring 107 is compressed and deformed under the movement of the second clamp 106. The operator places the oil pipe between the first clamp 104 and the second clamp 106, releases the movable rod 105, and the compressed telescopic spring 107 springs back to its original position after being released from force.This causes the second clamp 106 to spring back to its original position, and together with the first clamp 104, it clamps and secures the oil pipe. Thus, the movement of the movable rod 105 and the return of the telescopic spring 107 quickly fix the oil pipe to the first clamp 104 and the second clamp 106 bracket, reducing installation and disassembly time and improving oil pipe inspection efficiency.

[0024] Secondly, the first fixing seat 111 is fixedly connected to the fixing frame 102 and the telescopic spring 107 respectively, and the first fixing seat 111 is located on the side of the fixing frame 102 near the telescopic spring 107; the second fixing seat 112 is fixedly connected to the second clamp 106 and the telescopic spring 107 respectively, and the second fixing seat 112 is located on the side of the second clamp 106 near the telescopic spring 107. There are two first fixing seats 111, and the two first fixing seats 111 are welded to one end of the corresponding two fixing frames 102 and two telescopic springs 107. There are two second fixing seats 112, and the two second fixing seats 112 are welded to the other end of the corresponding two second clamps 106 and two telescopic springs 107. Thus, the two ends of the telescopic spring 107 can be connected and fixed to the fixing frame 102 and the second clamp 106 through the first fixing seat 111 and the second fixing seat 112.

[0025] Meanwhile, the pull ring 108 is fixedly connected to the movable rod 105 and is located on the side of the movable rod 105 away from the second clamp 106. There are two pull rings 108, and the two pull rings 108 are welded to the corresponding two movable rods 105. The pull rings 108 make it easy for the operator to move the movable rod 105 on the fixed frame 102.

[0026] In addition, the first rubber pad 109 is fixedly connected to the first clamp 104 and located on one side of the first clamp 104; the second rubber pad 110 is fixedly connected to the second clamp 106 and located on one side of the second clamp 106. There are two first rubber pads 109, which are bonded to the corresponding two first clamps 104. There are two second rubber pads 110, which are bonded to the corresponding two second clamps 106. The first rubber pad 109 and the second rubber pad 110 can increase the friction when the first clamp 104 and the second clamp 106 abut against and clamp the oil pipe, thereby making the oil pipe better fixed in the first clamp 104 and the second clamp 106.

[0027] Finally, the movable through hole is located on the side of the fixed frame 102 close to the movable rod 105 and cooperates with the movable rod 105. The movable rod 105 can move in the movable through hole of the fixed frame 102. The movable through hole can achieve the purpose of directional and limited movement of the movable rod 105 on the fixed frame 102.

[0028] When using the oil pipe airtightness inspection tool of this embodiment, if the oil pipe needs to be fixed on the workbench 101, the operator moves the movable rod 105 to the right, thereby moving the second clamp 106 to the right. At the same time, the telescopic spring 107 is compressed and deformed under the action of the movement of the second clamp 106. The operator places the oil pipe between the first clamp 104 and the second clamp 106, releases the movable rod 105, and causes the compressed telescopic spring 107 to spring back to its original position after being no longer under force, and drives the second clamp 106 to spring back to its original position. Together with the first clamp 104, the oil pipe is clamped and fixed. Thus, the movement of the movable rod 105 and the springback of the telescopic spring 107 can quickly fix the oil pipe to the first clamp 104 and the second clamp 106 bracket, thereby reducing the installation and disassembly time and improving the oil pipe inspection efficiency.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
