Description

Technical Field

[0001] The utility model relates to the field of position switches, in particular to a position switch which can be quickly disassembled and assembled based on a displacement sensor. Background Art

[0002] A position switch is a device used to detect the position or state of an object. When the object reaches a specific position or state, the position switch triggers the switch action and generates a corresponding signal output. This type of switch is usually used in applications such as automatic control, safety monitoring and position detection.

[0003] In some advanced position switch designs, displacement sensors are integrated inside the position switch to detect the position of an object or a mechanical device. This design enables the position switch to have more accurate position detection capabilities, thereby achieving higher levels of control and monitoring functions.

[0004] When installing existing position switches, most of them are fixed inside machinery and other devices by bolts to achieve the detection effect. However, in some machines with relatively narrow space, it is troublesome and inconvenient to install the position switch to the position and rotate the bolts to fix it. In addition, the installation angle position of the bottom of the existing position switch is fixed. When installed on different machines, the reserved installation holes of the machine may be different, and thus it is impossible to adjust according to the installation feet of the position switch. Therefore, a position switch based on a displacement sensor that can be quickly disassembled and assembled is proposed to solve the above problems. Utility Model Content

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Reference Figure 1-Figure 3 The utility model provides an embodiment: a position switch based on a displacement sensor that can be quickly disassembled and assembled, including a shell 1. The shell 1 is an existing position switch technology. A displacement sensor is integrated inside the position switch to detect the position of an object or a mechanical device. The integrated design can simplify the installation and configuration of the system and improve the reliability and accuracy of the system. The inner walls of the bottom ends of both sides of the shell 1 are clamped with four groups of sliding seats 3 through limit components 5. The inner walls of the bottom ends of both sides of the shell 1 are provided with sliding grooves. The sliding seat 3 is slidably connected to the inner wall of the sliding groove at the bottom end of the shell 1. The sliding seat 3 is moved laterally on the inner wall of the bottom end of the shell 1, so that the installation can be adjusted according to the installation hole positions of different installation plates 2.

[0038] Reference Figure 3-Figure 4 The inner wall of the sliding seat 3 is provided with a fixing assembly 4, and the fixing assembly 4 includes four groups of fixing columns 41. The outer walls of the fixing columns 41 are slidably connected to the inner wall of the sliding seat 3. The inner wall of the sliding seat 3 is provided with a cavity so as to fit the outer wall of the fixing columns 41. The outer walls of the bottom ends of the four groups of fixing columns 41 are provided with external threads 42. The outer wall of the external threads 42 is threadedly connected with a mounting plate 2. The mounting plate 2 is a prior art, which is a specific installation position of the shell 1 as a whole inside a machine or other device, and the interior of the mounting plate 2 is provided with an internal thread that fits the external thread 42. The bottom end of the outer wall of the shell 1 contacts the surface of the mounting plate 2.

[0039] Reference Figure 4The inner wall of the top of the fixed column 41 is slidably connected with a push block 43, and a round block is arranged at the bottom of the push block 43, so that the push block 43 can only move up and down on the inner wall of the fixed column 41 and cannot be separated from the inner wall. The inner wall of the fixed column 41 is slidably connected with two groups of moving rods 44, and the top of the outer wall of the two groups of moving rods 44 is provided with inclined surfaces, and the inclined surfaces of the top of the two groups of moving rods 44 are in contact with the inner wall of the bottom of the push block 43. The contact between the two allows the push block 43 to descend on the inner wall of the fixed column 41, so that the push block 43 will squeeze the inclined surfaces of the two groups of moving rods 44 when descending, so as to allow They are close to each other, and the two groups of moving rods 44 are elastically connected by a limit spring 45. The function of the limit spring 45 is to automatically reset the position of the two groups of moving rods 44 after being squeezed and moved. The outer side walls of the two groups of moving rods 44 are fixedly connected with a clamping block 46, and the inner side wall of the sliding seat 3 is provided with two groups of slots. The bottom ends of the outer walls of the two groups of clamping blocks 46 are clamped with the inner walls of the slots. The clamping between the two fixes the fixing component 4 as a whole to the inner wall of the sliding seat 3, thereby facilitating the installation of the shell 1 as a whole. The clamping block 46 penetrates and is slidably connected to the inner wall of the fixing column 41.

[0040] Reference Figure 5-Figure 6 The limit assembly 5 includes a limit block 51. The inner wall of the slide groove at the bottom end of the shell 1 is provided with multiple groups of through holes. The top of the outer wall of the limit block 51 is plugged into the inner wall of the through hole. The plugging between the two fixes the sliding seat 3 at multiple positions of the inner wall of the shell 1, so that it can be adjusted to fit the hole positions of various mounting plates 2. The limit block 51 is slidably connected to the inner wall of the sliding seat 3. The top of the left side of the limit block 51 is provided with an inclined surface. The triangular block 53 contacts the inclined surface of the limit block 51. The two contact each other, so that the inclined surface of the limit block 51 is squeezed by the triangular block 53 to allow the limit block 51 to drop, so that the sliding seat 3 is released from fixation, and the triangular block 53 is slidably connected to the inner wall of the sliding seat 3. The limit block 51 is elastically connected to the inner wall of the sliding seat 3 through a return spring 52, one end of the return spring 52 is fixedly connected to the bottom end of the outer wall of the limit block 51, and the other end of the return spring 52 is fixedly connected to the bottom end of the inner wall of the sliding seat 3. The function of the return spring 52 is to automatically reset the position of the limit block 51 after being squeezed and moved. A moving column 54 is penetrated and slidably connected to the inner wall of the sliding seat 3, and the bottom end of the outer wall of the moving column 54 is fixedly connected to a triangular block 53, which is driven by the moving column 54 to move laterally on the inner wall of the sliding seat 3.

[0041] Working principle: When installing the housing 1, first in a narrow environment, you can manually grasp the fixing column 41 to allow the external thread 42 at its bottom to be rotated and locked with the internal thread of the mounting plate 2. At this time, you can adjust the position of the corresponding sliding seat 3 according to the position of the four groups of fixing columns 41 on the mounting plate 2, and press the moving column 54 to drive the triangular block 53 to move on the inner wall of the sliding seat 3, so that when the triangular block 53 moves on the inner wall of the sliding seat 3, the inclined surface at the bottom end will squeeze the inclined surface at the top of the limit block 51. Thereby, the limit block 51 is allowed to descend on the inner wall of the sliding seat 3, and the return spring 52 is elastically compressed. At this time, the sliding seat 3 can be adjusted to align with the position of the fixed column 41 installed on the mounting plate 2. After alignment, the movable column 54 is released, and the limit block 51 is elastically acted upon by the return spring 52 to restore it to its original position, thereby squeezing the inclined surface of the triangular block 53, and synchronously restoring it and the movable column 54 to their original positions, so that the limit block 51 is plugged into the through hole at the current position to fix the position of the sliding seat 3.

[0042] At this time, you can directly grasp the shell 1 to move the through holes of the four groups of sliding seats 3 on its outer wall on the outer wall of the fixed column 41 until the position of the block 46 is reached, the outer wall of the sliding seat 3 will squeeze the inclined surface of the block 46, so that the two groups of blocks 46 drive the moving rod 44 to move toward each other synchronously, and the limit spring 45 is elastically compressed until the block 46 completely enters the corresponding groove of the sliding seat 3, the two groups of moving rods 44 will be elastically acted upon by the limit spring 45, and will synchronously restore them and the block 46 to their initial positions, thereby fixing the sliding seat 3 on the outer wall of the fixed column 41 to prevent it from falling off during use.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
