Description

Technical Field

[0001] This application relates to the field of industrial equipment, and in particular to a switch life detector. Background Technology

[0002] Currently, with the rapid development of modern technology and information, electronic switches are being used more and more. Existing switch life detectors use cylinders for testing. This type of switch life tester is completed by the action of the cylinder. The lifespan of the switch is tested as the pressure of the cylinder changes.

[0003] Regarding the aforementioned technologies, there are still some shortcomings: the switch life detector is equipped with multiple sets of detectors, and each set of detectors has multiple cylinders. When installing the cylinders, the installers need to tighten the cylinders one by one with bolts, which is cumbersome, time-consuming and labor-intensive. It is not possible to quickly install multiple cylinders on the same set of detectors, so further improvements are needed. Utility Model Content

[0004] To facilitate quick installation of cylinders by installers, this application provides a switch life detector.

[0005] This application provides a switch life detector, which adopts the following technical solution:

[0006] A switch life detector includes a detection box and multiple detection frames mounted on the detection box. Each detection frame has multiple detection cylinders detachably connected to it. The side wall of each detection frame has a mounting cavity, and a limit rod is rotatably connected to the extended end of the mounting cavity. A positioning rod is integrally formed along the extension direction of the mounting cavity. A connecting block is provided on the outer periphery of each detection cylinder, and the connecting block has an annular connecting groove. A first connecting screw block is provided at the free end of the positioning rod, and a second connecting screw block is provided on the detection frame. When the limit rod or positioning rod is inserted into the connecting groove, the first connecting screw block and the second connecting screw block combine to form a bolt structure. A nut is threadedly connected to the bolt structure.

[0007] By adopting the above technical solution, a linear assembly channel is provided through the mounting cavity, and the rotatable limiting rod and the integrally formed positioning rod form a "pin-type" locking base. When the limiting rod or positioning rod is inserted into the annular connecting groove of the cylinder connecting block, the first and second connecting screw blocks automatically combine into a bolt structure with continuous threads, requiring only a single nut to simultaneously tighten all cylinders. Compared with the traditional method of tightening bolts one by one, the assembly efficiency is improved, and the bolt structure and nut form an axial locking force, making the cylinder connecting block and the testing frame rigidly connected.

[0008] Optionally, the connecting block is a rectangular block; when all the detection cylinders are installed in the mounting cavity, the connecting blocks of adjacent detection cylinders abut against each other, and the connecting block of the detection cylinder at the end abuts against the side wall of the mounting cavity.

[0009] By adopting the above technical solution, the right-angled side design of the rectangular connecting block ensures tight planar contact between adjacent cylinders, eliminating circumferential rotational freedom; the hard contact between the end cylinder connecting block and the side wall of the mounting cavity forms a mechanical limit. This layout reduces the parallelism error of the piston rod axes of multiple cylinders, avoiding switching bias wear caused by cylinder tilting. The array of connecting blocks forms a distributed load-bearing frame, evenly transmitting the impact force during cylinder operation to the testing frame.

[0010] Optionally, the positioning rod is made of magnetic material and can be magnetically connected to the connecting block.

[0011] By adopting the above technical solution, the magnetic positioning rod actively attracts the iron connecting block when the cylinder slides into the mounting cavity, providing holding force and preventing the cylinder from accidentally slipping out before it is locked. The magnetic attraction helps the cylinder connecting block automatically fit against the bottom surface of the mounting cavity, reducing the axial deviation between the annular connecting groove and the positioning rod, and reducing the difficulty of manual alignment.

[0012] Optionally, the end of the nut away from the limiting rod is integrally formed with a plurality of rod-shaped hand-held parts, which extend radially away from the limiting rod.

[0013] By adopting the above technical solution, the radially extending rod-shaped handpiece forms a lever structure, allowing for manual tightening of nuts, saving operation time compared to traditional hexagonal nuts. The height of the handpiece when folded is much greater than that of a normal nut, enabling manual operation even when the testing racks are densely arranged, thus solving the problem of wrench accessibility.

[0014] Optionally, after the limiting rod is inserted into the annular connecting groove, its exposed portion is provided with multiple anti-slip stripes, which are distributed circumferentially along the limiting rod.

[0015] By adopting the above technical solution, the anti-slip stripes on the limit rod enhance the friction during manual rotation and prevent slippage during operation.

[0016] Optionally, the end of the positioning rod facing the connecting block is chamfered.

[0017] By adopting the above technical solution, the chamfer at the end of the positioning rod provides a guiding insertion function, reducing the difficulty of aligning the connecting block and the positioning rod.

[0018] Optionally, the testing chamber is equipped with a temperature regulator.

[0019] By adopting the above technical solution, the temperature regulator expands the test operating range and simulates the impact of real ambient temperature on the switch life.

[0020] In summary, the beneficial technical effects of this application are as follows: the synergy between the modular mechanical locking structure and the magnetic pre-fixing design enables efficient and stable assembly and disassembly of multiple detection cylinders; the combination of the self-aligning contact layout of the rectangular connecting blocks and ergonomic optimization significantly improves assembly efficiency and testing stability; and with the addition of environmental temperature control capabilities, a switch life testing system with rapid deployment, high reliability, and multi-condition simulation is formed.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0027] This application discloses a switch lifetime detector. (Refer to...) Figure 1 , Figure 2 A switch life detector comprises a rectangular detection box 1 and multiple parallel detection frames 2 mounted on top of the detection box 1. Each detection frame 2 has a mounting cavity 4 along its length on its side wall. One end of the mounting cavity 4 is rotatably connected to a limiting rod 5 via a pivot. The exposed portion of the limiting rod 5 is machined with anti-slip stripes 13 distributed along its circumference.

[0028] Meanwhile, a positioning rod 6 extends integrally from the other end of the mounting cavity 4 toward the limiting rod 5. This positioning rod 6 is made of magnetic material (such as magnetized stainless steel), and its end facing the cylinder mounting area has a chamfer to facilitate insertion. Its free end (the end near the limiting rod 5) is fixed with a first connecting screw block 9. A second connecting screw block 10 is fixedly installed on the detection frame 2 near the root of the limiting rod 5. The second connecting screw block 10 and the first connecting screw block 9 are designed to be coaxial so that they can be combined in a specific state.

[0029] Reference Figure 1 , Figure 2 as well as Figure 3 A rectangular connecting block 7 is fixedly fitted around the outer periphery of the test cylinder 3 to be installed. The connecting block 7 has an annular connecting groove 8 extending through its thickness at its center for the test cylinder 3 to be inserted. During installation, multiple test cylinders 3 are pushed sequentially into the mounting cavity 4 of the test frame 2, causing the positioning rod 6 to pass sequentially through the annular connecting groove 8 on each cylinder connecting block 7. Because the positioning rod 6 is magnetic, it can attract and hold the cylinder's connecting block 7, achieving initial positioning and pre-fixation of the cylinder.

[0030] During this process, the rectangular connecting blocks 7 of adjacent cylinders abut against each other tightly, while the connecting blocks 7 at both ends of the queue abut against the side walls of the mounting cavity 4, ensuring that all cylinders are arranged neatly and in accurate positions.

[0031] Next, manually rotate the limiting rod 5 so that it is inserted into the annular connecting groove 8 of the cylinder connecting block 7 located at the other end of the queue (i.e., the side closer to the limiting rod 5). When both the limiting rod 5 and the positioning rod 6 are successfully inserted into the annular connecting groove 8 of the corresponding connecting block 7, the first connecting screw block 9 and the second connecting screw block 10 are exactly aligned and in close contact, forming a complete bolt structure together.

[0032] Finally, a specially designed nut 11 is screwed onto the bolt structure formed by the assembly for final tightening and locking. The end of the nut 11 opposite to the limiting rod 5 has multiple (e.g., four) radially extending rod-shaped handles 12 integrally formed to facilitate manual tightening by the operator.

[0033] Reference Figure 1 The test chamber 1 is also equipped with a temperature regulator (such as a PTC heater or a thermoelectric cooler) to adjust the temperature inside the chamber during testing, simulating the working state of the switch under different ambient temperatures. During testing, the switch under test is fixed below the piston rod of the corresponding cylinder inside the test chamber 1, the temperature parameters are set, and the pneumatic system is started to drive all cylinders to perform reciprocating pressing actions synchronously. The number of failure cycles of the switch can then be recorded to complete the life test.

[0034] This application discloses an implementation principle of a switch life detector: the device simulates switch on / off states using a cylinder array and accurately tests lifespan in conjunction with a temperature-controlled environment. During installation, first, the limiting rod 5 is vertically opened. Holding the cylinder, the connecting block 7 is aligned with the magnetic positioning rod 6 and pushed into the mounting cavity 4. After ensuring the adjacent rectangular connecting blocks 7 of the cylinders are tightly abutted, the anti-slip texture of the limiting rod 5 is gripped and rotated to a horizontal position, embedding into the end cylinder connecting groove 8. At this time, the screw block at the end of the positioning rod 6 and the screw block of the detection frame 2 automatically combine to form a bolt. The radial handheld part 12 of the nut 11 is unfolded, and it is tightened clockwise until slight resistance is felt to complete the locking.

[0035] Before testing, fix the switch to be tested below the cylinder and set the temperature range. After startup, the system automatically records the number of presses and the failure status. Disassembly is done in reverse order: loosen nut 11, push up limit rod 5, and pull out the cylinder array. During maintenance, periodically clean the magnetic poles of positioning rod 6 with alcohol to ensure stable adsorption force.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
