[0022] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In the prior art, conventional laser rangefinders and electric displacement sensors are welded and fixed on the equipment housing 9 in advance. Once the axial depth of the later assembly component 15 changes or the sensor fixing position deviates, the connection between the sensor and the housing 9 needs to be repaired, disassembled, readjusted and then fixed. For underwater equipment with many detection points, it is bound to bring great inconvenience to the personnel in the repair work and affect the progress of the underwater equipment test.

[0024] Therefore, it is necessary to design a variable distance travel detection switch suitable for underwater equipment, which does not contain an electronic unit and has the characteristics of simple structure, fine adjustment of distance, long-distance and large-angle combined adjustment of distance, etc. Figure 1 It is a structural schematic diagram of a variable distance travel detection switch provided by an embodiment of the present invention that is not in operation; Figure 2 is a schematic diagram of the structure of a variable distance travel detection switch after actuation provided by an embodiment of the present invention; Figure 1 and Figure 2 As shown, the variable distance travel detection switch includes:

[0025] 1. The slide table 1 is detachably fixed in the housing 9;

[0026] Specifically, the slide platform 1 can rotate 360 ​​degrees in the housing 9. A mounting hole 12 is provided on the slide platform 1 for passing a mounting screw 13 to fix the slide platform 1 in the housing 9.

[0027] 2. A sliding wall frame 2, fixedly connected to the sliding seat platform 1;

[0028] Specifically, the slide platform 1 and the sliding wall frame 2 are an integrated structure. In the present invention, the sliding wall frame 2 and the slide platform 1 are arranged at an obtuse angle.

[0029] 3. A slide 3 is slidably fixed in the sliding wall frame 2;

[0030] Specifically, a limiting hole 10 is provided on the sliding wall frame 2 , which is used for passing a top screw 11 through to fix the slide 3 in a groove of the sliding wall frame 2 . Figure 3 2 is a schematic diagram of the structure of the sliding wall frame 2 locking the sliding platform 3 provided in an embodiment of the present invention, as shown in FIG. Figure 3 As shown, loosen the top screw 11 to ensure that the slide 3 can move freely in the groove of the sliding wall frame 2.

[0031] There are multiple limit holes 10, that is, the limit holes 10 are evenly distributed on the sliding wall frame 2, so that when the slide 3 moves in a small range in the groove of the sliding wall frame 2, the slide 3 can be fixed at another position of the groove of the sliding wall frame 2 by passing the top screw 11 through another limit hole 10, thereby realizing fine-tuning operation.

[0032] Furthermore, a mounting step 14 is provided on the shell 9; the mounting step 14 corresponds to the position of the slide 3; a component 15 can be installed on the mounting step 14. In the specific implementation process, the mounting screw 13 is first loosened, and the slide table 1 is rotated according to the reserved mounting hole position of the shell 9 and the approximate size of the component 15, thereby driving the slide arm frame to rotate at a large angle and long distance, until the slide 3 on the slide arm frame is roughly in line with the position of the mounting step 14, and the mounting screw 13 is locked.

[0033] 4. A detection plug 4, both ends of which are arranged in the slide 3;

[0034] Specifically, two ends (end A and end B) of the detection plug 4 are arranged in the slide 3; and both the end A and the end B are connected to the internal parts of the detection plug 4 through wires.

[0035] 5. An adjusting unit, comprising: a pressing plate 5, a support rod 6, a spring 7 and a spring leaf 8; the pressing plate 5 is fixedly connected to the top of the slide 3; the support rod 6 is arranged under the pressing plate 5 and the bottom end of the support rod 6 is fixedly connected to the spring leaf 8; the spring leaf 8 is arranged in the slide 3, and one end of the spring leaf 8 is fixedly connected to one end of the detection plug 4; the spring 7 is arranged on the periphery of the support rod 6 and is located between the top end of the support rod 6 and the top end of the slide 3; when a pressure is applied to the pressing plate 5, the support rod 6 is squeezed downward and the spring 7 is compressed, thereby connecting the other end of the spring leaf 8 to the other end of the detection plug 4, so that the detection plug 4 is in a connected state; when no pressure is applied to the pressing plate 5, the spring 7 is in a normal telescopic state, and the detection plug 4 is in a disconnected state.

[0036] Specifically, the assembly 15 installed on the installation step 14 is used to apply pressure to the pressure plate 5. One end of the pressure plate 5 is fixedly connected to the top of the slide 3, and the pressure plate 5 and the top surface of the slide 3 are arranged at an acute angle; the acute angle is greater than 45 degrees; the slide 3 and the pressure plate 5 are an integrated structure.

[0037] The support rod 6 is a T-shaped support rod 6 ; the bottom end of the support rod 6 is fixedly connected to the top surface of the spring leaf 8 .

[0038] The reed 8 is a metal reed 8 ; one end (left end) of the metal reed 8 is fixedly connected to one end (end A) of the detection plug 4 .

[0039] When the assembly 15 applies pressure to the pressure plate 5, the pressure plate 5 squeezes the T-shaped support rod 6, and the spring 7 is compressed; the T-shaped support rod 6 presses down the metal spring sheet 8, and the metal spring sheet 8 is deformed by the force and contacts the B end of the detection plug 4. At this time, the A end and the B end of the detection plug 4 are in a connected state;

[0040] When the assembly 15 is removed from the mounting step 14 of the housing 9, the pressure plate 5 on the slide 3 is free of pressure, the spring 7 returns to its normal telescopic state, and drives the T-shaped support rod 6 to move upward, and the metal spring 8 returns to its initial state at the same time, disconnecting the connection with the B end of the detection plug 4, and the A end and the B end of the detection plug 4 are in a disconnected state.

[0041] The present invention is described below by a specific embodiment:

[0042] 1. If the distance between the pressure plate 5 and the assembly component 15 on the slide 3 is too large, and the position of the slide 3 needs to be adjusted over a long distance and a large angle range, the mounting screws 13 can be loosened, and the slide table 1 can be rotated according to the reserved mounting holes in the housing 9 and the approximate size of the assembly component 15, thereby driving the slide arm frame to rotate over a large angle and a long distance, until the slide 3 on the slide arm frame is roughly in line with the position of the mounting step 14, and the mounting screws 13 are locked.

[0043] Second, loosen the top screw 11 to ensure that the slide 3 can move freely in the groove of the slide arm frame, the pressure plate 5 connected to the slide 3 is not forced to squeeze the T-shaped support rod 6, the metal spring 8 of the slide 3 is in a state of no force and relaxation, and the A end and B end of the detection plug 4 are in a disconnected state;

[0044] 3. Install the assembly component 15 on the installation step 14 of the shell 9, fine-tune the position of the slide 3 on the slide arm frame until the pressure plate 5 fixedly connected to the slide 3 is fully stressed, and lock the top screw 11 through the limit hole 10 to fix the slide 3 in the groove of the sliding wall frame 2.

[0045] Step 4: The pressing plate 5 connected to the slide 3 squeezes the T-shaped support rod 6, compresses the spring 7, and the T-shaped support rod 6 presses down the metal spring sheet 8. The metal spring sheet 8 is deformed by the force and contacts the B end of the detection plug 4, so that the A end and the B end of the detection plug 4 are in a connected state;

[0046] Step 5. Remove the assembly 15 from the mounting step 14 of the housing 9. The pressure plate 5 connected to the slide 3 is free of pressure. The spring 7 returns to its normal telescopic state and drives the T-shaped support rod 6 to move upward. The metal spring 8 also returns to its initial state and disconnects the B end of the detection plug 4. Then, the A end and the B end of the detection plug 4 are in a disconnected state.

[0047] The present invention adopts a rotating slide table 1 with an extended arm span structure, and the slide table 3 adopts a free movement and locking design, and utilizes the 1360-degree rotation of the slide table to drive the large-angle adjustment characteristics of the slide arm frame, thereby solving the technical problem of free adjustment of the stroke detection switch over a long distance and within a large angle range; the slide table 3 utilizes the evenly distributed limit holes 10 of the slide arm frame to achieve fine-tuning operation, thereby solving the problem of accurate control of the stroke detection switch after the assembly component 15 is installed; compared with traditional stroke detection sensors (for example: laser rangefinders, electric displacement sensors), the stroke detection switch does not contain an electronic unit, thereby solving the problem of free adjustment of the position of the stroke detection switch and variable distance detection technology, and has the characteristics of simple structure, large range of activity after installation, and strong adaptability.
