Description

Technical Field

[0001] This utility model belongs to the field of micro switch technology, and in particular relates to a micro switch mounting structure. Background Technology

[0002] As a sensitive switching element with tiny contact intervals and a fast-acting mechanism, microswitches are widely used in many fields such as home appliances, industrial control equipment, automotive electronic systems, and intelligent instruments due to their rapid response and precise control.

[0003] In existing technologies, the mounting structure of micro switches mostly adopts fixed-size slots or single-size clamps, which can only be adapted to micro switches of a specific width.

[0004] This means that when upgrading equipment or replacing microswitches with different models, the entire mounting base often needs to be replaced, which not only increases production and maintenance costs but also severely limits the compatibility and expandability of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a micro switch mounting structure. By setting a clamping component, specifically by rotating the knob on the left side of the lead screw, the lead screw will rotate between two support blocks. Because the outer surface of the lead screw has a bidirectional thread, it will synchronously drive the slider on the back of the clamping block to move towards each other. The two clamping blocks then move closer to the micro switch and clamp and fix it from the left and right sides. This effectively adapts to the fixing needs of micro switches of various sizes and solves the problem that the existing micro switch mounting structure can only adapt to micro switches of a specific width.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a micro switch mounting structure, including a mounting base, a clamping assembly, and a positioning assembly. The top of the mounting base is fixedly connected to a mounting groove, and a micro switch is disposed inside the mounting groove. The clamping assembly is installed inside the mounting groove to clamp and fix the micro switch. The clamping assembly includes:

[0008] Two clamping blocks are slidably connected to the left and right sides of the mounting groove, respectively, with the corresponding sides of the two clamping blocks contacting the left and right sides of the micro switch.

[0009] Two sliders are fixedly connected to the front and back of the clamping block respectively. A slot is opened on the outer surface of the mounting groove near the slider. The outer surface of the slider extends through the slot of the mounting groove to the outside and slides in connection with the inner wall of the slot.

[0010] Two support blocks are fixedly connected to the top of the mounting base on one side near the back of the mounting groove. A lead screw is rotatably connected to the corresponding side of the two support blocks. The threads on the outer surface of the lead screw are set in two opposite directions. The outer surface of the lead screw is connected to the internal thread of the slider located on the back of the clamping block. A knob is fixedly connected to the left side of the lead screw.

[0011] The positioning component is installed on the outer surface of the mounting slot and is used to position the micro switch.

[0012] Furthermore, two support blocks are fixedly connected to the top of the mounting base near the front of the mounting groove. Slide rods are fixedly connected to the corresponding sides of the two support blocks, and the outer surface of the slide rods is slidably connected to the inside of the slider located on the front of the clamping block.

[0013] Furthermore, a magnetic snap fastener is fixedly connected to the inner wall at the bottom of the mounting slot, with the top of the magnetic snap fastener contacting the bottom of the micro switch.

[0014] Furthermore, the positioning component includes:

[0015] Two positioning holes are respectively opened on the front and back of the micro switch. A positioning block is provided on the side of the outer surface of the mounting groove near the positioning hole. A positioning pin is fixedly connected to the side of the positioning block near the micro switch. The positioning pin passes through the outer surface of the mounting groove and extends into the interior. The outer surface of the positioning pin is inserted into the inner wall of the positioning hole.

[0016] A chute is formed on the top of the positioning block, and a connecting rod is provided above the positioning block. The bottom of the connecting rod is slidably connected to the inner wall of the chute through a sliding block.

[0017] The drive rod is fixedly connected to the right side of the two connecting rods. Several telescopic rods are fixedly connected between the drive rod and the mounting groove. Springs are sleeved on the outer surface of the telescopic rods.

[0018] Furthermore, a limiting guide rail is fixedly connected to the side of the outer surface of the mounting groove near the positioning block, and the inner wall of the limiting guide rail is slidably connected to the outer surface of the positioning block.

[0019] Furthermore, a limiting block is fixedly connected to the side of the outer surface of the mounting groove near the connecting rod, and the inside of the limiting block is slidably connected to the outer surface of the connecting rod.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model sets up a clamping component. Specifically, by rotating the knob on the left side of the lead screw, the lead screw will rotate between two support blocks. Because the outer surface of the lead screw is a bidirectional thread, it will synchronously drive the slider on the back of the clamping block to move towards each other. The two clamping blocks then move closer to the micro switch and clamp and fix it from the left and right sides, effectively adapting to the fixing requirements of micro switches of various sizes.

[0022] 2. This utility model, by setting a positioning component, specifically by pressing the drive rod, will drive the connecting rods on both sides to move synchronously. The sliding block at the bottom of the connecting rod slides along the groove at the top of the positioning block, thereby driving the positioning block to move and causing the positioning pin to retract from the inside of the mounting groove. Then, the micro switch is placed inside the mounting groove and clamped and fixed by the clamping component. At this time, the spring force drives the drive rod to reset, thereby allowing the positioning pin to be accurately inserted into the positioning hole to achieve positioning, thus improving the stability of the installation structure.

[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-5 As shown, this utility model has the following two specific embodiments.

[0034] Example 1

[0035] This utility model relates to a micro switch mounting structure, including a mounting base 1, a clamping assembly 2, and a positioning assembly 3. The top of the mounting base 1 is fixedly connected to a mounting groove 11, and a micro switch 12 is disposed inside the mounting groove 11. The clamping assembly 2 is installed inside the mounting groove 11 to clamp and fix the micro switch 12. The clamping assembly 2 includes:

[0036] Two clamping blocks 21 are slidably connected to the left and right sides of the mounting groove 11, respectively, and the corresponding sides of the two clamping blocks 21 are in contact with the left and right sides of the micro switch 12, respectively.

[0037] Two sliders 211 are fixedly connected to the front and back of the clamping block 21 respectively. The outer surface of the mounting groove 11 is provided with a slot on the side near the slider 211. The outer surface of the slider 211 extends through the slot of the mounting groove 11 to the outside and is slidably connected to the inner wall of the slot.

[0038] Two support blocks 213 are fixedly connected to the top of the mounting base 1 on one side near the back of the mounting groove 11. A lead screw 214 is rotatably connected to the corresponding side of the two support blocks 213. The threads on the outer surface of the lead screw 214 are set in two opposite directions. The outer surface of the lead screw 214 is threadedly connected to the inner thread of the slider 211 located on the back of the clamping block 21. A knob 215 is fixedly connected to the left side of the lead screw 214.

[0039] The positioning component 3 is installed on the outer surface of the mounting slot 11 and is used to position the micro switch 12.

[0040] like Figures 1-2 As shown, by setting the clamping component 2, specifically by rotating the knob 215 on the left side of the lead screw 214, the lead screw 214 will rotate between the two support blocks 213. Since the outer surface of the lead screw 214 has a bidirectional thread, it will synchronously drive the slider 211 on the back of the clamping block 21 to move towards each other. The two clamping blocks 21 will then move closer to the micro switch 12 and clamp and fix it from the left and right sides, effectively adapting to the fixing requirements of micro switches of various sizes.

[0041] Two support blocks 22 are fixedly connected to the top of the mounting base 1 near the front of the mounting groove 11. A slide rod 221 is fixedly connected to the corresponding side of the two support blocks 22. The outer surface of the slide rod 221 is slidably connected to the inside of the slider 211 located on the front of the clamping block 21.

[0042] The sliding rod 221 slides in contact with the slider 211 on the front of the clamping block 21, providing additional guidance and limiting constraints for the movement of the clamping block 21, ensuring that the clamping block 21 always maintains a horizontal translational state.

[0043] A magnetic snap fastener 13 is fixedly connected to the inner wall of the bottom of the mounting slot 11, and the top of the magnetic snap fastener 13 contacts the bottom of the micro switch 12.

[0044] like Figure 3 As shown, a magnetic snap 13 is provided at the bottom of the mounting groove 11 and contacts the bottom of the micro switch 12, which can realize the pre-fixation of the micro switch 12 and provide convenience for subsequent clamping and positioning processes.

[0045] Example 2

[0046] The difference from Embodiment 1 is that this embodiment discloses how the positioning component 3 specifically implements the positioning operation of the micro switch 12:

[0047] Positioning component 3 includes:

[0048] Two positioning holes 31 are respectively opened on the front and back of the micro switch 12. A positioning block 32 is provided on the side of the outer surface of the mounting groove 11 near the positioning hole 31. A positioning pin 321 is fixedly connected to the side of the positioning block 32 near the micro switch 12. The positioning pin 321 passes through the outer surface of the mounting groove 11 and extends into the interior. The outer surface of the positioning pin 321 is inserted into the inner wall of the positioning hole 31.

[0049] A sliding groove 322 is formed on the top of the positioning block 32. A connecting rod 33 is provided above the positioning block 32. The bottom of the connecting rod 33 is slidably connected to the inner wall of the sliding groove 322 through a sliding block.

[0050] A drive rod 34 is fixedly connected to the right side of two connecting rods 33. Several telescopic rods 341 are fixedly connected between the drive rod 34 and the mounting groove 11. Springs 342 are sleeved on the outer surface of the telescopic rods 341.

[0051] like Figures 4-5As shown, by setting the positioning component 3, specifically by pressing the drive rod 34, the drive rod 34 will drive the connecting rods 33 on both sides to move synchronously. The sliding block at the bottom of the connecting rod 33 slides along the sliding groove 322 on the top of the positioning block 32, thereby driving the positioning block 32 to move, causing the positioning pin 321 to retract from the inside of the mounting groove 11. Then, the micro switch 12 is placed inside the mounting groove 11 and clamped and fixed by the clamping component 2. At this time, the elastic force of the spring 342 drives the drive rod 34 to reset, thereby allowing the positioning pin 321 to be accurately inserted into the positioning hole 31 to achieve positioning, improving the stability of the installation structure.

[0052] A limiting guide rail 323 is fixedly connected to the side of the outer surface of the mounting groove 11 near the positioning block 32, and the inner wall of the limiting guide rail 323 is slidably connected to the outer surface of the positioning block 32.

[0053] A limiting block 331 is fixedly connected to the side of the outer surface of the mounting groove 11 near the connecting rod 33, and the inside of the limiting block 331 is slidably connected to the outer surface of the connecting rod 33.

[0054] The positioning guide rail 323 can accurately guide and limit the movement trajectory of the positioning block 32, ensuring that the positioning block 32 drives the positioning pin 321 to always move in the preset direction; the limiting block 331 slides with the connecting rod 33, which can strictly constrain the movement direction of the connecting rod 33, preventing the connecting rod 33 from shaking or deviating during transmission, and ensuring the synchronicity and accuracy of the movement of the positioning block 32 driven by the connecting rod 33.

[0055] A specific application of this embodiment is as follows: When using this micro switch mounting structure, the operator first presses the drive rod 34, which drives the connecting rods 33 on both sides to move synchronously. At this time, the telescopic rod 341 is compressed, the spring 342 stores force, and the sliding block at the bottom of the connecting rod 33 slides along the groove 322 at the top of the positioning block 32. At the same time, the positioning block 32 moves away from the mounting groove 11 along the limit guide rail 323, causing the positioning pin 321 to retract from the inside of the mounting groove 11. Then, the micro switch 12 is placed into the mounting groove 11 at the top of the mounting base 1, so that the bottom of the micro switch 12 contacts the magnetic snap 13 at the bottom of the mounting groove 11 to achieve pre-fixation. Then, the knob 215 on the left side of the lead screw 214 is rotated, and the lead screw 214 rotates between the two support blocks 213. Because the outer surface of the lead screw 214 is bidirectional threaded, it will synchronously drive the slider 211 on the back of the clamping block 21 to move towards each other. When the microswitch 1 is moved, the slider 211 on the front of the clamping block 21 slides synchronously along the slide bar 221 between the support blocks 22. The two clamping blocks 21 then move closer to the microswitch 12 and clamp it from the left and right sides. After that, the drive rod 34 is released. The reset force of the telescopic rod 341, combined with the elastic rebound force of the spring 342, will push the drive rod 34 to reset. The drive rod 34 drives the connecting rod 33 to move. The connecting rod 33 will push the positioning block 32 to reset along the limit guide rail 323. At the same time, the limit block 331 will limit and guide the movement of the connecting rod 33, so that the positioning pin 321 is accurately inserted into the positioning hole 31 of the microswitch 12 to complete the positioning. When it is necessary to disassemble the microswitch 12, simply press the drive rod 34 again to make the positioning pin 321 disengage from the positioning hole 31, rotate the knob 215 in the opposite direction to make the clamping blocks 21 move in opposite directions to release the clamping, and then take the microswitch 12 out of the mounting slot 11.
