Description

Technical Field

[0001] The invention belongs to the technical field of pressure resistance detection, and in particular relates to a pressure resistance tester for vehicle air circuits and brake circuits. Background Art

[0002] In modern vehicles, the air circuit and brake pipe system play a vital role. The vehicle's air circuit system is responsible for providing the necessary air pressure power for the braking system, suspension system, door opening and closing system, etc., and the brake pipe is directly related to the driving safety of the vehicle. It transmits the force applied by the brake pedal to the brakes of each wheel through hydraulic or air pressure, thereby achieving effective braking of the vehicle. Since the brake pipe is under considerable pressure during the braking process of the vehicle, once the pipe has insufficient pressure resistance, such as rupture, leakage and other failures under high pressure, it will cause a sharp decline in braking efficiency or even complete failure, which poses a very serious threat to the driving safety of the vehicle. Similarly, if the pressure resistance of other parts of the air circuit system is poor, it may also affect the normal operation of related systems, and indirectly affect driving safety. In order to ensure the safety of vehicles, all countries have formulated strict automotive industry regulations and standards, with clear and detailed provisions on the pressure resistance performance of vehicle air circuits and brake pipes, and stipulate the minimum pressure value that the brake pipe should be able to withstand under specific working conditions, and the pipe must remain intact after a certain number of pressure cycle tests.

[0003] During the detection process, existing instruments need to carry a large number of detection harnesses. Therefore, when the instrument is not in use, the detection harnesses need to be properly stored and managed. A large number of harnesses require a large storage space. At the same time, the harnesses are prone to being randomly stacked and squeezed against each other. This will not only lead to problems such as cumbersome wiring and easy entanglement when used next time, but may also accelerate the aging and damage of the harnesses. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a vehicle air circuit and brake pipe pressure tester.

[0005] The technical solution adopted to solve the above technical problems is: a vehicle air circuit and brake pipeline pressure tester, including a dustproof box, the front end of the outer wall of the dustproof box is fixedly connected with a hinge and a lock, the upper end face of the inner wall of the dustproof box is fixedly connected with a sealing strip, the inner wall of the dustproof box is slidably connected with the detector body, the bottom of the inner wall of the dustproof box is installed with an anti-loosening component and a storage component, the anti-loosening component is fixedly connected with a winding rod, and the outer wall of the winding rod is rotatably connected with a winding wheel.

[0006] Furthermore, a sealing groove is provided on the top of the dustproof box, and the sealing strip matches the sealing groove.

[0007] Through the above technical scheme, a tight sealing structure can be formed to prevent external dust from entering the box to a great extent, and good sealing can reduce the contact between the items in the box and the external environment, reduce the damage to the box body caused by factors such as oxidation and corrosion, thereby improving the durability of the dustproof box, and preventing other small foreign objects from entering the dustproof box, further ensuring the purity of the environment in the box, and avoiding these foreign objects from causing potential interference or damage to the items in the box.

[0008] Furthermore, the anti-loosening component includes a first mounting groove and a sliding groove opened at the rear end of the inner wall of the dustproof box, an electric motor is installed on the inner wall of the first mounting groove, a two-way threaded rod is fixedly connected to the bottom of the electric motor, and clamping plates are threadedly connected at both upper and lower ends of the outer wall of the two-way threaded rod, and sliding blocks are fixedly connected to the front ends of the two clamping plates.

[0009] Through the above technical solution, the test line is first wound around the outer wall of the winding wheel, and then the winding wheel is slidably connected to the outer wall of the winding rod, and then the electric motor is started, so that the electric motor drives the bidirectional threaded rod to rotate. At the same time, the bidirectional threaded rod will drive the two clamping plates to move relative to each other until the inner walls of the two clamping plates are in contact with the test line on the outer wall of the winding rod, thereby achieving the purpose of preventing loosening.

[0010] Furthermore, the two clamping plates are both slidably connected to the inner wall of the slide groove, and the outer wall of the bidirectional threaded rod matches the inner walls of the two clamping plates.

[0011] Through the above technical solution, the entire clamping device forms a relatively stable structural system during the working process. The clamping plate is driven by the bidirectional threaded rod and constrained by the slide groove. The various components cooperate and support each other, and can withstand certain external force impact and vibration without easily causing problems such as structural loosening or deformation, thereby improving the stability of the clamping device.

[0012] Furthermore, the two sliding blocks are both slidably connected to the front end of the inner wall of the dustproof box.

[0013] Through the above technical solution, the slider can only move linearly along the direction specified by the box wall during movement, which effectively avoids arbitrary offset, swinging and other unstable situations, and improves stability during movement. At the same time, from the installation perspective, it is usually relatively simple and direct to slide the slider to the front end of the inner wall of the dustproof box. This connection method does not require an overly complicated assembly process. It only requires ensuring that the slider can be accurately embedded and can slide smoothly on the box wall. This reduces the installation difficulty of the entire equipment or device to a certain extent and improves the installation efficiency.

[0014] Furthermore, the storage component includes a second mounting groove on the dustproof box, two limit plates are fixedly connected to the front end of the bottom of the dustproof box, a lifting door is slidably connected between the two limit plates, a handle is fixedly connected to the front end of the outer wall of the lifting door, a plurality of guide holes are provided on the top of the lifting door, a plurality of limit rings are fixedly connected to the top of the inner walls of the guide holes, a plurality of guide rods are slidably connected to the inner walls of the limit rings, a plurality of anti-slip disks are fixedly connected to the bottoms of the guide rods, and a plurality of anti-slip disks are slidably connected to the outer walls of the anti-slip disks.

[0015] Through the above technical solution, first put the items to be placed into the dustproof box, and then use the downward elastic force of multiple springs to drive the lifting door to move downward along the outer walls of multiple guide rods until the bottom of the lifting door fits with the inner wall of the dustproof box. When you want to take the items, you only need to lift the handle upwards so that the handle drives the lifting door to move upward along the outer walls of multiple guide rods.

[0016] Furthermore, the outer walls of the plurality of guide rods match the corresponding inner walls of the limiting rings, and the outer walls of the plurality of anti-slip disks fit tightly with the corresponding inner walls of the guide holes.

[0017] Through the above technical solution, the restraining effect of the limit ring on the guide rod can effectively prevent the relevant components from being dislocated during movement. When subjected to external force or high-speed movement, this structure can keep the relative position of the components stable and avoid equipment failure or damage caused by dislocation. At the same time, it makes it safer for operators to work around the equipment, reduces the possibility of damage to the surrounding environment during operation, and improves the safety and reliability of equipment use.

[0018] Furthermore, the distances between every two of the limiting rings, the guide rods, the anti-slip discs and the springs are equal.

[0019] Through the above technical solution, the equally spaced design helps to evenly disperse the stress to various limit rings, guide rods and other components. When the equipment is subjected to external force, there will be no local stress concentration, which reduces the risk of component damage and extends the service life of the equipment. At the same time, the limit rings, guide rods, anti-slip discs and springs can be installed one by one quickly and accurately according to the fixed interval distance, without spending too much time to adjust the relative positions of the components, which greatly shortens the installation time and improves the installation efficiency.

[0020] The beneficial effects of the present invention are as follows: (1) The present invention can effectively reduce such unnecessary friction and shaking by setting an anti-loosening component and maintaining the stability of the wiring harness, thereby extending the service life of the detection harness, reducing the frequency of harness replacement, and saving equipment maintenance costs. At the same time, it can also ensure that the harness is always firmly connected to the winding wheel to ensure the stable transmission of signals and electrical energy during the test, thereby ensuring that the test work can be carried out continuously and stably without interruption or abnormality due to loose wiring harness problems; (2) The present invention can provide a convenient storage space by setting a storage component, so that the staff can access these tools at any time. At the same time, the staff does not need to carry other tool kits or containers when performing detection work, which is more convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] like Figure 1 - Figure 7 As shown, a vehicle air circuit and brake pipeline withstand pressure tester of the present embodiment includes a dustproof box 1, the front end of the outer wall of the dustproof box 1 is fixedly connected with a hinge 2 and a lock 3, the upper end face of the inner wall of the dustproof box 1 is fixedly connected with a sealing strip 4, and a sealing groove 401 is opened on the top of the dustproof box 1, and the sealing strip 4 matches the sealing groove 401; a tight sealing structure can be formed to prevent external dust from entering the box to a great extent, and a good seal can reduce the contact between the items in the box and the external environment, reduce the damage to the box body caused by oxidation, corrosion and other factors, thereby improving the durability of the dustproof box 1, and can also prevent other small foreign objects from entering the dustproof box 1, further ensuring the purity of the environment in the box, and avoiding these foreign objects from causing potential interference or damage to the items in the box, and the inner wall of the dustproof box 1 is slidably connected with a detector body 5.

[0031] like Figure 5 and Figure 7As shown, an anti-loosening component 6 and a storage component 7 are installed at the bottom of the inner wall of the dustproof box 1. The anti-loosening component 6 includes a first installation groove 601 and a slide groove 603 opened at the rear end of the inner wall of the dustproof box 1. An electric motor 602 is installed on the inner wall of the first installation groove 601. A two-way threaded rod 604 is fixedly connected to the bottom of the electric motor 602. The upper and lower ends of the outer wall of the two-way threaded rod 604 are threadedly connected to clamping plates 605. The front ends of the two clamping plates 605 are fixedly connected to sliders 606. First, wrap the test wire around the outer wall of the winding wheel 9 , then the winding wheel 9 is slidably connected to the outer wall of the winding rod 8, and then the electric motor 602 is started, so that the electric motor 602 drives the bidirectional threaded rod 604 to rotate. At the same time, the bidirectional threaded rod 604 drives the two clamping plates 605 to move relative to each other until the inner walls of the two clamping plates 605 are in contact with the test line of the outer wall of the winding rod 8, thereby achieving the purpose of preventing loosening. The two clamping plates 605 are slidably connected to the inner wall of the slide groove 603, and the outer wall of the bidirectional threaded rod 604 is in contact with the two clamping plates 605. The inner wall matches; the entire clamping device forms a relatively stable structural system during operation, the clamping plate 605 is driven by the bidirectional threaded rod 604 and constrained by the slide groove 603, and the various components cooperate and support each other, and can withstand certain external force impact and vibration without easily causing problems such as structural loosening or deformation, thereby improving the stability of the clamping device, and the two sliders 606 are slidably connected to the front end of the inner wall of the dustproof box 1; the slider 606 can only move linearly along the direction specified by the box wall during movement, effectively avoiding its random offset, swinging and other unstable situations, thereby improving its stability during movement. At the same time, from an installation perspective, sliding the slider 606 to the front end of the inner wall of the dustproof box 1 is usually relatively simple and direct. This connection method does not require an overly complicated assembly process. It only needs to ensure that the slider 606 can be accurately embedded and can slide smoothly on the box wall. This reduces the installation difficulty of the entire equipment or device to a certain extent and improves the installation efficiency.

[0032] like Figure 1 , Figure 3 and Figure 6As shown, the anti-loosening component 6 is fixedly connected to a winding rod 8, and the outer wall of the winding rod 8 is rotatably connected to a winding wheel 9. The storage component 7 includes a second mounting groove 701 opened on the dustproof box 1, and two limit plates 702 are fixedly connected to the front end of the bottom of the dustproof box 1. A lifting door 703 is slidably connected between the two limit plates 702. A handle 704 is fixedly connected to the front end of the outer wall of the lifting door 703. A plurality of guide holes 705 are opened on the top of the lifting door 703. The tops of the inner walls of the plurality of guide holes 705 are fixedly connected to limit rings 706, and the inner walls of the plurality of limit rings 706 are slidably connected to guide rods 707. The bottom is fixedly connected with an anti-slip plate 708, and the outer walls of multiple anti-slip plates 708 are slidably connected with springs 709; first, the items to be placed are put into the dustproof box 1, and then the downward elastic force of multiple springs 709 drives the lifting door 703 to move downward along the outer walls of multiple guide rods 707 until the bottom of the lifting door 703 fits with the inner wall of the dustproof box 1. When you want to take the items, you only need to lift the handle 704 upward so that the handle 704 drives the lifting door 703 to move upward along the outer walls of multiple guide rods 707. The outer walls of multiple guide rods 707 match the corresponding inner walls of limit rings 706. The outer wall of each anti-slip disk 708 is tightly fitted with the inner wall of the corresponding guide hole 705; the restraining effect of the limiting ring 706 on the guide rod 707 can effectively prevent the relevant components from being dislocated during the movement. When subjected to external force or high-speed movement, this structure can keep the relative position of the components stable and avoid equipment failure or damage caused by dislocation. At the same time, it makes it safer for operators to work around the equipment, and also reduces the possibility of damage to the surrounding environment during operation of the equipment, thereby improving the safety and reliability of the equipment. 08 and the spring 709 are all at the same distance; the equally spaced design helps to evenly disperse the stress to various components such as the limit ring 706 and the guide rod 707. When the equipment is subjected to external force, there will be no local stress concentration, which reduces the risk of component damage and extends the service life of the equipment. At the same time, the limit ring 706, the guide rod 707, the anti-slip disk 708 and the spring 709 can be quickly and accurately installed one by one according to the fixed interval distance, without spending too much time to adjust the relative positions of the components, which greatly shortens the installation time and improves the installation efficiency.

[0033] The working principle of this embodiment is as follows. First, the test line is wound around the outer wall of the winding wheel 9, and then the winding wheel 9 is slidably connected to the outer wall of the winding rod 8, and then the electric motor 602 is started, so that the electric motor 602 drives the bidirectional threaded rod 604 to rotate. At the same time, the bidirectional threaded rod 604 will drive the two clamping plates 605 to move relative to each other until the inner walls of the two clamping plates 605 are in contact with the test line on the outer wall of the winding rod 8, thereby achieving the purpose of preventing loosening. After the items to be placed are placed in the dust-proof box 1, the downward elastic force of multiple springs 709 is then used to drive the lifting door 703 to move downward along the outer walls of multiple guide rods 707 until the bottom of the lifting door 703 is in contact with the inner wall of the dust-proof box 1. When you want to take the items, you only need to lift the handle 704 upward so that the handle 704 drives the lifting door 703 to move upward along the outer walls of multiple guide rods 707.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
