Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a sealing detection device for a filter element. Background Art

[0002] The sealing test of the filter element is mainly used to ensure that the filter element will not leak water or leak during operation, so as to maintain its filtering performance and the safety of the equipment. By applying air pressure, the filter element is tested for gas leakage under a specific pressure. Commonly used equipment includes air tightness testers. The sealing test process of the filter element: Tighten the filter element accurately on the detection device to ensure that it has good contact with the sealing surface, check whether the various functions of the detection device are normal, and ensure a leak-free environment. Apply the specified pressure through the detection device to simulate the sealing conditions under the working state. Monitor whether there is liquid or gas leakage at the connection between the filter element and the device. Usually, a gas leak detector or a liquid leak detector can be used. Record the test results, including whether it is qualified and the specific leakage amount. If the test fails, it may be necessary to reinstall the filter element or adjust the sealing ring, and then repeat the above test process. Through these steps, the sealing of the filter element can be effectively tested to ensure its reliability during use.

[0003] Testing a filter element requires precisely tightening it onto the test device. Threaded connections rely on friction and tightening force to maintain the connection. As the nut or filter element is tightened, friction between the threads increases, creating a tightening effect. Appropriate tightening force creates sufficient preload to form a good seal between the filter element and the device, while excessive force can lead to concentrated compressive stress and increase the risk of damage. Novices or inexperienced personnel often misjudge the tightening force, easily over-tightening or under-tightening the filter element, potentially compromising the filter element.

[0004] In view of this, we propose a filter element sealing detection device. Utility Model Content

[0005] The purpose of the utility model is to provide a filter element sealing detection device, which solves the problem that the staff's lack of experience may cause improper control of the tightening force, resulting in damage to the threaded connection or poor sealing.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The top of the filter element is fixedly connected to the filter element, and the bottom of the filter element is fixedly connected to the filter element of the filter element.

[0008] Preferably, the quick-release mechanism includes an extension groove, which is provided on the inner wall of the connecting seat, a slope block is fixedly connected to the inner wall of the connecting seat, an arc surface is provided on the inner wall of the connecting seat, and a toggle rod is fixedly connected to the top of the guide plate.

[0009] Preferably, the outer wall of the limit block is slidably connected to the inner wall of the sliding groove, and the side of the limit block away from the spring 1 is trapezoidal.

[0010] Preferably, the outer wall of the guide rod is slidably connected to the inner wall of the top annular member, and four limit blocks are provided, and the four limit blocks are arranged in a circular array.

[0011] Preferably, the number of the semi-threaded parts is two, and the two semi-threaded parts are symmetrically arranged.

[0012] Preferably, a cylindrical groove is provided on the top of the connecting seat, and the extending groove is located on the side of the cylindrical groove on the top of the connecting seat.

[0013] Preferably, the top annular member and the bottom annular member are connected via a cylindrical rod, and the surface of the trapezoidal block away from the guide plate is arc-shaped.

[0014] By means of the above technical solution, the present invention provides a filter element sealing detection device, which has at least the following beneficial effects:

[0015] (1) The utility model sets a connecting mechanism until the fastening force between the filter element and the semi-threaded part reaches an appropriate level. At this time, the spring is compressed and the limit block retracts into the sliding groove, so that when the limit block and the trapezoidal block slide relative to each other, the sound and feedback force generated by the relative resistance between the limit block and the trapezoidal block can be easily perceived by people. At this time, the filter element is stopped from being rotated to tighten, so as to avoid excessive fastening force causing damage to the thread of the filter element.

[0016] (2) The utility model is provided with a quick-release mechanism. The guide plate, the trapezoidal block and the semi-threaded member are driven by hand to rotate in opposite directions by the toggle lever, so that the trapezoidal block moves to the area of ​​the extension groove. At this time, the inclined block contacts the side of the trapezoidal block, so that the trapezoidal block moves into the extension groove, so that the trapezoidal block drives the guide plate and the semi-threaded member, so that the two semi-threaded members move away from each other. At this time, the filter element can be quickly removed, which plays a role in quick disassembly, avoids excessive threaded connections from damaging the threads of the filter element, and plays a role in further protecting the product.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-6As shown, the utility model provides a technical solution: a sealing detection device for a filter element, comprising a workbench 1, a base 2 is provided on the workbench 1, and a connecting mechanism 3 is provided on the top of the base 2, the connecting mechanism 3 comprises: a connecting seat 31, the connecting seat 31 is fixedly connected to the top of the base 2, a sliding groove 32 is opened on the top of the connecting seat 31, one end of a spring 1 33 is fixedly connected to the inner wall of the sliding groove 32, and the other end of the spring 1 33 is fixedly connected to the limiting block 34, a bottom ring member 35 is rotatably connected to the inner wall of the connecting seat 31, a top ring member 311 is fixedly connected to the top of the bottom ring member 35, a spring 2 36 is fixedly connected to the inner wall of the top ring member 311, a guide plate 38 is fixedly connected to both sides of the spring 2 36, a guide rod 37 is fixedly connected to the inner wall of the guide plate 38, a trapezoidal block 39 is fixedly connected to the outer wall of the guide rod 37, and a semi-threaded member 310 is fixedly connected to the side of the guide plate 38 away from the trapezoidal block 39; a quick release mechanism 4 is provided on the connecting seat 31. The filter element is threadedly connected between the two semi-threaded parts 310. The semi-threaded part 310 rotates due to the friction force. The semi-threaded part 310 drives the guide rod 37 to rotate. The guide rod 37 drives the guide plate 38 and the trapezoidal block 39 to rotate until the trapezoidal block 39 contacts the limit block 34. Until the fastening force between the filter element and the semi-threaded part 310 reaches a suitable level, the spring 1 33 is compressed and the limit block 34 retracts into the sliding groove 32, so that when the limit block 34 and the trapezoidal block 39 slide relative to each other, the sound and feedback force generated by the relative conflict between the limit block 34 and the trapezoidal block 39 can be easily perceived.

[0027] The quick-release mechanism 4 includes an extension groove 41, which is provided on the inner wall of the connecting seat 31. A sloped block 42 is fixedly connected to the inner wall of the connecting seat 31. An arc-shaped surface 43 is provided on the inner wall of the connecting seat 31. A toggle rod 44 is fixedly connected to the top of the guide plate 38. The toggle rod 44 is used by hand to drive the guide plate 38, the trapezoidal block 39 and the semi-threaded member 310 to rotate in opposite directions, so that the trapezoidal block 39 moves to the area of ​​the extension groove 41. At this time, the sloped block 42 contacts the side of the trapezoidal block 39, so that the trapezoidal block 39 moves into the extension groove 41, so that the trapezoidal block 39 drives the guide plate 38 and the semi-threaded member 310, so that the two semi-threaded members 310 move away from each other. At this time, the filter element can be quickly removed.

[0028] The outer wall of the limit block 34 is slidably connected to the inner wall of the sliding groove 32. The side of the limit block 34 away from the spring 1 33 is trapezoidal. When the force of the trapezoidal block 39 against the limit block 34 reaches a certain level, the trapezoidal inclined surface of the limit block 34 can be retracted into the sliding groove 32, so that the limit block 34 and the trapezoidal block 39 slide relative to each other, and the outer wall of the guide rod 37 is slidably connected to the inner wall of the top ring member 311. The limit blocks 34 are provided with four, and the four limit blocks 34 are arranged in a circular array. When the limit block 34 and the trapezoidal block 39 slide relative to each other, the sound and feedback force generated by the relative conflict between the limit block 34 and the trapezoidal block 39 are easily perceived by people, which serves as a reminder. There are two half-threaded parts 310, and the two half-threaded parts 310 are arranged symmetrically so that the two half-threaded parts 310 can be connected to thread the filter element.

[0029] A cylindrical groove is provided at the top of the connecting seat 31, and the extending groove 41 is located on the side of the cylindrical groove at the top of the connecting seat 31. When the trapezoidal block 39 rotates to the position of the extending groove 41, it enters the extending groove 41 under the action of the spring 2 36. The top ring member 311 and the bottom ring member 35 are connected by a cylindrical rod. The surface of the trapezoidal block 39 away from the guide plate 38 is arc-shaped, so that the trapezoidal block 39 fits more closely with the inner wall of the connecting seat 31.

[0030] When the sealing detection device of a filter element of the present invention is in use, the filter element is threadedly connected between the two semi-threaded parts 310, and the semi-threaded part 310 is rotated by the friction force, and the semi-threaded part 310 drives the guide rod 37 to rotate, and the guide rod 37 drives the guide plate 38 and the trapezoidal block 39 to rotate until the trapezoidal block 39 contacts the limit block 34, until the fastening force between the filter element and the semi-threaded part 310 reaches a suitable level, at this time the spring 1 33 is compressed, and the limit block 34 is retracted into the sliding groove 32, so that when the limit block 34 and the trapezoidal block 39 slide relative to each other, the sound and feedback force generated by the relative conflict between the limit block 34 and the trapezoidal block 39 can be easily perceived by people. At this time, the filter element is stopped from being rotated to tighten, so as to avoid damage to the thread of the filter element caused by excessive fastening force.

[0031] When disassembly is required, the guide plate 38, the trapezoidal block 39 and the semi-threaded member 310 are driven by hand to rotate in the opposite direction by the toggle rod 44, so that the trapezoidal block 39 moves to the area of ​​the extension groove 41. At this time, the inclined block 42 contacts the side of the trapezoidal block 39, so that the trapezoidal block 39 moves into the extension groove 41, so that the trapezoidal block 39 drives the guide plate 38 and the semi-threaded member 310, so that the two semi-threaded members 310 move away from each other. At this time, the filter element can be quickly removed, which plays a role in quick disassembly, avoids excessive threaded connections from damaging the threads of the filter element, and plays a role in further protecting the product.
