Description

Technical Field

[0001] This utility model relates to the field of limit switch technology, and in particular to an adjustable elevator limit switch. Background Technology

[0002] Elevators, as indispensable vertical transportation equipment in modern high-rise buildings, directly impact the safety and reliability of passengers' lives and property. Limit switches play a crucial role in elevator operation. They are key safety devices used to control the elevator's position and travel distance. When the elevator reaches specific locations (such as floor stops, upper or lower limits), they promptly send signals, enabling the elevator control system to accurately execute stopping, reversing, and other operations. This prevents the elevator from exceeding its normal operating range and avoids serious accidents such as overshooting or bottoming out. Traditional elevator limit switches are typically fixed in place, with their trigger positions and travel parameters largely determined after installation, making flexible adjustments difficult to meet actual usage needs. When the elevator shaft structure changes, floor height is adjusted, or elevator operating parameters need optimization, traditional limit switches often require disassembly and reinstallation. This not only increases maintenance costs and workload but may also lead to prolonged elevator downtime, affecting normal elevator operation. Utility Model Content

[0003] This invention proposes an adjustable elevator limit switch to solve the problem that existing devices require complete disassembly when adjusting their installation position.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable elevator limit switch, including a fixing member, a switch member on one side of the fixing member, a connecting member on the side of the switch member facing the fixing member, side brackets fixedly connected to both sides of the connecting member symmetrically, an annular groove formed by the recessed circumference of the fixing member, the side of the connecting member away from the switch member being rotatably connected to the fixing member, the free ends of both side brackets being inside the annular groove, and a second limiting rod being screwed onto both side brackets, the free end of the second limiting rod extending into the annular groove and abutting against the fixing member.

[0005] Preferably, the connector includes a connecting frame, one side of which is open to form a groove, and the other side is rotatably connected to a fixing member. A connecting plate is slidably connected inside the groove, and a first limiting rod is rotatably connected to the connecting frame. The free end of the first limiting rod extends into the groove and abuts against the connecting plate.

[0006] Preferably, one side of the connecting plate is recessed inward along its sliding direction to form a side groove, and the side groove matches the first limiting rod.

[0007] Preferably, the fixing member includes a base plate, on which a fixing screw is screwed and connected, and the annular groove is formed on the circumferential surface of the base plate.

[0008] Preferably, the switching element includes a switch body, and a rotating rod for triggering the switch body is rotatably connected to one side of the switch body.

[0009] Preferably, the free end of the rotating rod is rotatably connected to a roller.

[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0011] (1) By setting a fixing part, annular groove, side frame and second limiting rod, the switch is fixed in the adjusted position by rotating the connecting part and the second limiting rod around the annular groove on the fixing part during use, and rotating the second limiting rod. This eliminates the need to disassemble when the switch needs to be reinstalled and repositioned. This not only reduces maintenance costs and workload, but also shortens elevator downtime and does not affect the normal use of the elevator.

[0012] (2) By setting up a connecting frame, a sliding groove, a connecting plate and a first limiting rod, the device can be used by sliding the connecting plate along the sliding groove and rotating the first limiting rod, so that the extension length can also be adjusted after the limit switch is installed, which further increases the scope of use of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-8 An adjustable elevator limit switch is shown, including a fixing member 3. A switch member 1 is provided on one side of the fixing member 3. A connecting member 2 is provided on the side of the switch member 1 facing the fixing member 3. Side brackets 23 are fixedly connected to both sides of the connecting member 2 symmetrically. The circumferential surface of the fixing member 3 is recessed to form an annular groove 33. The side of the connecting member 2 away from the switch member 1 is rotatably connected to the fixing member 3. The free ends of the two side brackets 23 are both inside the annular groove 33, and a second limiting rod 24 is screwed onto both side brackets 23. The free end of the second limiting rod 24 extends into the annular groove 33 and abuts against the fixing member 3.

[0025] When installing switch 1, fix the fixing part 3. After fixing the fixing part 3, pull switch 1 to make switch 1 drive the connecting part 2 to rotate together, thereby driving the side frame 23 to rotate around the annular groove 33 on the fixing part 3, thereby adjusting the angle of switch 1. After the angle of switch 1 is adjusted, rotate the second limiting rod 24 on the side frame 23 to move the second limiting rod 24 relative to the side frame 23 until the free end of the second limiting rod 24 moves into the interior of the annular groove 33 and presses the fixing part 3, thereby fixing the position of the side frame 23 and the connecting part 2, and completing the position adjustment of switch 1. When the elevator moves, the switch 1 is triggered to limit the elevator.

[0026] Specifically, in one embodiment, regarding the aforementioned connector 2, as... Figures 1-6As shown, the connector 2 includes a connector 21. One side of the connector 21 is open to form a groove 25, and the other side is rotatably connected to the fixing member 3. A connecting plate 26 is slidably connected inside the groove 25, and a first limiting rod 22 is rotatably connected to the connector 21. The free end of the first limiting rod 22 extends into the groove 25 and abuts against the connecting plate 26.

[0027] In this embodiment, when the position of switch 1 needs to be adjusted, switch 1 is pulled, causing switch 1 to drive connecting frame 21 to rotate around fixing member 3, thereby adjusting the position of switch 1, connecting frame 21 and connecting plate 26. The second limiting rod 24 on side frame 23 is rotated, causing the second limiting rod 24 to move relative to side frame 23 until the free end of the second limiting rod 24 moves into the interior of annular groove 33 and presses against fixing member 3, thereby fixing the position of side frame 23 and connecting member 2. If the operator needs to continue adjusting the extension position of switch 1, the first limiting rod 22 is loosened, and switch 1 is pulled, causing switch 1 to drive connecting plate 26 to slide along slide groove 25 on connecting frame 21. After the position of switch 1 is adjusted, the first limiting rod 22 is tightened, causing the first limiting rod 22 to press against connecting plate 26, fixing connecting plate 26 and switch 1 in the adjusted position, thus completing the adjustment of the extension length of switch 1.

[0028] After adjusting the position of the switch 1, in order to facilitate the first limit rod 22 pressing the connecting plate 26, as follows: Figures 4-5 As shown, one side of the connecting plate 26 is recessed inward along its own sliding direction to form a side groove 27, which matches the first limiting rod 22.

[0029] In this embodiment, when the first limiting rod 22 presses against the connecting plate 26, the side groove 27 cooperates to make the position of the connecting plate 26 and the switch 1 more secure after adjustment.

[0030] Specifically, in one embodiment, regarding the aforementioned fastener 3, as... Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the fastener 3 includes a base plate 31, a fixing screw 32 is screwed onto the base plate 31, and an annular groove 33 is formed on the circumferential surface of the base plate 31.

[0031] In this embodiment, when it is necessary to fix the substrate 31, the substrate 31 is placed at the position to be fixed, and then the fixing screw 32 is rotated to move the fixing screw 32 relative to the substrate 31 until the fixing screw 32 abuts against the substrate 31, thereby fixing the substrate 31.

[0032] Furthermore, in this utility model, regarding the aforementioned switch element 1, as follows: Figures 1-6 As shown, the switch 1 includes a switch body 11, and a rotating rod 12 for triggering the switch body 11 is rotatably connected to one side of the switch body 11.

[0033] In this embodiment, when the rotating rod 12 is squeezed, the rotating rod 12 rotates, thereby triggering the switch body 11.

[0034] When the rotating rod 12 rotates, in order to make the rotation of the rotating rod 12 smoother, such as Figures 1-4 As shown, a roller 13 is rotatably connected to the free end of the rotating rod 12.

[0035] In this embodiment, when the rotating rod 12 rotates, the roller 13 rotates, making the rotation of the rotating rod 12 smoother.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
