Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, and more particularly to a reed switch state testing device. Background Art

[0002] A reed switch, also known as a reed switch, is an electronic component that uses a magnetic field to control the on / off state. It is widely used in the field of automation and is usually used to sense the on / off state of the magnetic field in the circuit. It consists of two or more iron reeds and a glass tube. Under the action of an appropriate magnetic field strength, the reeds attract each other and close. When the magnetic field weakens or disappears, the reeds separate, thereby changing the circuit state. Due to its simple structure, fast response speed and high reliability, it is widely used in magnetic field control, circuit control and other fields.

[0003] In the production and application of reed switches, a series of tests are usually required to ensure their correct working state and performance. For example, the Chinese patent application number 202220764081.2 discloses a reed switch tester, the structure of which includes: a detection platform; an electromagnetic inductor, fixedly arranged on the detection platform, with an induction coil arranged therein; a detection arm, fixedly arranged on the detection platform and extending outward relative to the electromagnetic inductor; a magnet clamp, arranged on one end of the detection arm close to the electromagnetic inductor, for fixing and clamping the magnet; a reed switch clamp, arranged on one end of the detection arm away from the electromagnetic inductor, for fixing and clamping the reed switch to be tested; and a display device for displaying the detection results of the reed switch. This reed switch tester still has the following problems during use:

[0004] 1. Since different types of reed switches have different lengths, this device cannot detect reed switches of different types and lengths, which limits its applicability.

[0005] 2. The operation steps are too complicated, which is not conducive to the testing of batch reed switches. It not only affects the production efficiency of reed switches, but also increases the workload of operators.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0024] See also Figure 1-3 A reed switch state testing device includes a test platform 101. A support frame 102 is fixedly connected to the bottom of the test platform 101. The support frame 102 is a supporting structure. A power supply 103 is installed on the top of the support frame 102. An indicator light 104, a magnetic field generator 105, a cable connector 106, a placement rack 107, and a symmetrical fixing ring 108 are installed on the top of the test platform 101. The power supply 103, the magnetic field generator 105, the indicator light 104, and the cable connector 106 are connected in series. The reed switch is detected by the power supply 103, the magnetic field generator 105, the indicator light 104, and the cable connector 106 connected in series. When one end of the reed switch connecting line is inserted into the cable connector 106, the entire circuit can be connected, so that the reed switch can be detected by the magnetic field generator 105.

[0025] refer to Figure 1 A sliding rod 109 is axially slidably connected to the symmetrical fixing ring 108, and the sliding rod 109 can be pulled by the handle 119 to move horizontally to adapt to reed switches of different lengths. A positioning ring 110 is axially slidably connected to the outer wall of the sliding rod 109. A pressure plate 111 is connected to the side of the positioning ring 110 facing the placement rack 107. The pressure plate 111 is used to press on both sides of the reed switch. The pressure plate 111 is a plastic sheet and will not affect the accuracy of the detection. By adjusting the distance between the two positioning rings 110, the effect of adapting to reed switches of different sizes and types can be achieved;

[0026] refer to Figure 1 A strip-shaped placement groove is provided on the top of the placement rack 107, which is used to place the reed switch. One end of the placement groove passes through the placement rack 107, and the other end of the placement groove is provided with an arc-shaped groove for placing the cable. The arc-shaped groove is used to place the signal line of the reed switch. The length of the pressure plate 111 exceeds the placement groove, and the pressure plate 111 can be driven to press on the placement rack 107 by rotating the handle 119.

[0027] Specifically, refer to Figure 3 The positioning ring 110 is provided with a through groove 112, and a pressure rod 113 is rotatably connected in the through groove 112. The pressure rod 113 is eccentrically arranged, and the eccentric arrangement can squeeze the block 116 so that the block 116 can be pressed in the sliding groove 117, and the positioning ring 110 can be fixed on the sliding rod 109. A guide groove 114 is provided on the inner ring surface of the positioning ring 110. The guide grooves 114 are located on both sides of the through groove 112. A moving rod 115 is slidably connected in the guide groove 114. The moving rod 115 has the function of limiting the movement of the block 116 to prevent the block 116 from escaping from the sliding groove 117. One end of the moving rod 115 is connected to the block 116.

[0028] Specifically, refer to Figure 2 An axially arranged sliding groove 117 is provided on the outer wall of the sliding rod 109 . The sliding groove 117 plays a limiting role, used to ensure that the pressure plate 111 and the handle 119 are located on the same side, and the block 116 is located in the sliding groove 117 .

[0029] Specifically, refer to Figure 2 A cotter pin 118 is inserted into one end of the sliding rod 109. The cotter pin 118 is used to limit the sliding rod 109 and prevent the sliding rod 109 from axial sliding, so that the sliding rod 109 can only rotate. A handle 119 is connected to the side of the sliding rod 109 away from the cotter pin 118, and the handle 119 is on the same side as the pressure plate 111.

[0030] In this embodiment, the handle 119 is opened upward, and the end of the reed switch to be tested is placed in the groove on the placement frame 107. The handle 119 is then pressed down so that the pressure plates 111 on the sliding rod 109 can press on both sides of the reed switch. The end of the reed switch with the connector is then inserted into the cable connector 106. At this time, the magnetic field generator 105, the indicator light 104, the reed switch and the power supply 103 are connected. When the reed switch can detect the magnetic field generator 105, the indicator light 104 will be activated, which proves that the reed switch can be used normally, and vice versa.

[0031] When the distance between the two pressing rods 113 needs to be adjusted to accommodate different types of reed switches, the pressing rod 113 is opened upwards so that the positioning ring 110 can slide on the sliding rod 109 , thereby adjusting the distance between the two pressing plates 111 .

[0032] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
