Description

Technical Field

[0001] This utility model relates to the field of proximity switch technology, specifically an adjustable proximity switch bracket. Background Technology

[0002] A proximity switch is a position switch that does not require direct mechanical contact with moving parts. When an object approaches the switch's sensing surface to the operating distance, the switch is activated, thereby driving DC electrical appliances or providing control commands to a computer (PLC) device. Also known as a contactless proximity switch, it is an ideal electronic switching sensor.

[0003] According to the adjustable proximity switch bracket disclosed in Chinese utility model CN217768149U, the mounting bracket of the proximity switch is installed on an external wall or equipment through a fixed base. The proximity switch mounting sleeve is connected to the fixed base through a sliding sleeve and a rack. The position of the proximity switch after installation can be finely adjusted by the meshing of the gear inside the sliding sleeve and the rack. Thus, the position and distance between the proximity switch and the object can be adjusted according to the needs during use, thereby improving the detection accuracy of the proximity switch.

[0004] However, the above-mentioned device controls the movement of the sliding sleeve through the meshing connection of gears and racks, thereby changing the position of the proximity switch. At the same time, the friction generated by the meshing connection of gears and racks allows the sliding sleeve to be positioned without external force. This method can only limit the sliding sleeve and cannot guarantee that the position of the sliding sleeve is fixed, resulting in the proximity switch not being effectively positioned. In actual use, the proximity switch will be subjected to vibrations generated by the moving mechanism. If it is not fixed, it will cause the proximity switch to deviate, affecting its actual use. In order to solve the above problems, we propose an adjustable proximity switch bracket. Utility Model Content

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0030] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] The proximity switch mounting bracket is installed on an external wall or equipment via a fixed base. The proximity switch mounting sleeve is connected to the fixed base via a sliding sleeve and a rack. The position of the proximity switch can be finely adjusted after installation by the meshing of the gear inside the sliding sleeve and the rack. This allows the position and distance between the proximity switch and the object to be adjusted as needed during use, thereby improving the detection accuracy of the proximity switch.

[0032] In related technologies, existing devices control the movement of the sliding sleeve through the meshing connection of gears and racks, thereby changing the position of the proximity switch. At the same time, the friction generated by the meshing connection of gears and racks allows the sliding sleeve to be positioned without external force. This method can only limit the sliding sleeve and cannot guarantee that the position of the sliding sleeve is fixed, resulting in the proximity switch not being effectively positioned. In actual use, the proximity switch will be subject to vibration generated by the moving mechanism. If it is not fixed, it will cause the proximity switch to deviate, affecting its actual use.

[0033] To address some of the problems in related technologies, this application provides an adjustable proximity switch bracket. The user can manually push the frame 13 horizontally on the first plate 12 as needed. After moving it to a suitable position, the user rotates the knob 242, which controls the screw 241 to rotate. Simultaneously, one side of the bottom of the limiting plate 24 is fixedly connected to the rod 23, and the other side is threadedly connected to the screw 241. The rod 23 passes through the frame 13 and the second plate 14. Therefore, as the knob 242 controls the screw 241 to rotate clockwise, the limiting plate 24 is fixedly connected to the screw 241. 41 descends, causing rod 23 and the toothed plate 231 on rod 23 to descend. The toothed plate 231 descends until it abuts against the rack 21. Because the fixed teeth on the toothed plate 231 are the same as the fixed teeth on the rack 21, the toothed plate 231 and the rack 21 are engaged. The user then turns the nut 243 clockwise. The nut 243 descends from the screw 241 and abuts against the plate 2 14. Therefore, the screw 241 stops rotating, and the engagement position of the toothed plate 231 and the rack 21 is fixed. At the same time, the position of the plate 2 14 is fixed, and the positions of the fixing clamp 15 on the plate 2 14 and the proximity switch body 16 are fixed.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Combination Figures 1-4 This application provides an adjustable proximity switch bracket, including a fixing device 1; the fixing device 1 includes: a plate 12 disposed on the inner sidewall of a frame 11, a frame 13 disposed on the top of the frame 11, a plate 14 disposed on the frame 13, a fixing hoop 15 disposed on the plate 14, and a proximity switch body 16 disposed on the fixing hoop 15; the fixing device 1 is provided with an adjusting device 2, the adjusting device 2 including: a rack 21 disposed on the plate 12; a gear 22 passing through a rotating shaft 2 21 is symmetrically and rotatably mounted on the frame 13, and the gear 22 and the rack 21 are meshed together; the rod 23 is inserted through the frame 13, and the bottom of the rod 23 is provided with a toothed plate 231, and a spring 232 is sleeved on the rod 23; the limiting plate 24 is provided on the top of the rod 23, and a screw 241 is inserted through the limiting plate 24, and a knob 242 is provided on the top of the screw 241 and the screw 241 is rotatably connected to the frame 13, and a nut 243 is threaded on the screw 241.

[0036] The user installs the frame 11 in a fixed position, and then uses a tool to remove the fixing clamp 15. The fixing clamp 15 is divided into two parts. One part is fixedly connected to the plate 14, and the other part is fixedly connected by bolts through the two fixing holes and nuts. Therefore, the user can use a tool to separate the bolts and nuts to separate the two parts of the fixing clamp 15. The proximity switch body 16 is placed between the two parts of the fixing clamp 15, and the bolts are then passed through the fixing holes and nuts are used to fix it. The rack 21 on the plate 12 and the gear 22 rotatably connected on the frame 13 are meshed. Therefore, the user can manually push the frame 13 to move horizontally on the plate 12 as needed. After moving to the appropriate position, the user turns the knob 242. The knob 242 controls the screw 241 to rotate, and at the same time, one side of the bottom of the limit plate 24 is fixedly connected to the rod 23. The other side is threaded to the screw 241. The rod 23 passes through the frame 13 and the plate 24. Therefore, as the knob 242 controls the screw 241 to rotate clockwise, the limit plate 24 descends on the screw 241, causing the rod 23 and the toothed plate 231 on the rod 23 to descend. The toothed plate 231 descends to abut against the rack 21. Because the fixing teeth on the toothed plate 231 and the fixing teeth on the rack 21 are the same, the toothed plate 231 and the rack 21 are engaged. The user then turns the nut 243 clockwise. The nut 243 descends up and down the screw 241 to abut against the plate 24. Therefore, the screw 241 stops rotating, and the engagement position of the toothed plate 231 and the rack 21 is fixed. At the same time, the position of the plate 24 is fixed, and the positions of the fixing clamp 15 on the plate 24 and the proximity switch body 16 are fixed to prevent the proximity switch body 16 from being unstable after the position is adjusted.

[0037] In some embodiments, the frame 11 is provided with a slide groove 254, and a slide block 251 is slidably disposed on the slide groove 254. The slide block 251 is fixedly connected to the plate 12. A screw 25 is provided at one end of the slide block 251, and a screw disc 252 is threaded onto the screw 25. When the user needs to make fine adjustments to the position of the proximity switch body 16, such as its height and horizontal position, the user can turn the screw disc 252 counterclockwise to loosen the position of the slide block 251. The user can then control the slide block 251 to move along the slide groove 254, thereby moving the plate 12 and making fine adjustments to the positions of the components disposed on the plate 12, further improving the flexibility of the entire device.

[0038] In some embodiments, a limiting block 253 is provided on the screw 25. The limiting block 253 prevents the screw disc 252 from falling off after adjustment and movement, thus improving the practicality of the device.

[0039] In some embodiments, the diameter of the screw disc 252 is larger than the diameter of the slide block 251. The screw disc 252 needs to abut against the slide block 251 to ensure that the slide block 251 is pressed onto the frame 11, and the slide block 251 stops moving under the action of friction. Setting the size of the screw disc 252 larger than that of the slide block 251 can ensure that the entire slide block 251 is pressed, thereby improving friction and fixing effect.

[0040] In some embodiments, the slide groove 254 is an irregularly shaped groove, and the slide block 251 consists of a slider and a clamping plate. The shape of the slide groove 254 determines the movement trajectory of the slide block 251, and the irregularly shaped groove provides more paths and adjustment directions for the slide block 251 to drive the plate 12 to move.

[0041] In some embodiments, there are two gears 22, symmetrically distributed on both sides of the toothed plate 231. The gears 22 on both sides of the toothed plate 231 ensure the stability of the plate body 12 during movement.

[0042] In some embodiments, a pad is provided on the retaining clamp 15. The pad provides protection for the housing of the proximity switch body 16 inside the retaining clamp 15.

[0043] In some embodiments, the frame 11 is provided with a keyway 26. The keyway 26 is generally long, and the distance between the preset fixing holes is different in different installation positions. Therefore, the keyway 26 facilitates the installation of the frame 11 in different positions.
