DETAILED DESCRIPTION

[0020] 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.

[0021] Example 1

[0022] See also Figure 1-Figure 4 , an impact-resistant and shock-resistant angular displacement sensor shown in the figure includes a body 1, and also includes a buffer component arranged on the body 1 for buffering the impact and vibration received during use;

[0023] The buffer assembly includes a buffer ring 201 arranged on one side of the body 1 close to the mounting end surface, a plurality of buffer rods 202 are fixedly connected to one side of the buffer ring 201 close to the mounting end surface of the body 1, a buffer tube 203 is sleeved on the side wall of each buffer rod 202, one end of each buffer tube 203 is connected to the mounting end surface of the body 1, a buffer plate 204 is fixedly connected to one end of each buffer rod 202 located inside the buffer tube 203, a first spring 205 is sleeved on the side wall of each buffer rod 202, two ends of each first spring 205 are respectively connected to the buffer ring 201 and the buffer tube 203, and each buffer tube 203 is provided with a damping assembly for damping impact and vibration force;

[0024] It should be noted here that: through the setting of the buffer component, under the action of the damping component, under the action of two layers of buffering protection, the impact and vibration received by the main body 1 during use are buffered and protected, thereby improving the impact and shock resistance of the main body 1, and further ensuring the measurement accuracy and service life of the angular displacement sensor. At the same time, with the setting of the protection component, when the main body 1 is subjected to a large impact and vibration, the damping effect will be increased, and the probability of the main body 1 receiving a large impact and vibration will be reduced, while reducing the probability of the buffer plate 204 contacting the bottom of the buffer tube 203, thereby further improving the service life of the buffer component.

[0025] It is worth noting that: as an existing technology, the specific structure and working principle of the angular displacement sensor have been mastered by people in this field, and will not be elaborated here.

[0026] See also Figure 1 , the buffer ring 201 shown in the figure is provided with a plurality of threaded holes 206 on one side away from the mounting end surface of the body 1;

[0027] It should be noted here that the provision of the threaded hole 206 facilitates the installation and connection of the angular displacement sensor, thereby ensuring the firmness of the installation of the angular displacement sensor while achieving the installation and connection of the angular displacement sensor.

[0028] See also Figure 1 , the buffer ring 201 shown in the figure is connected to the mounting end surface of the body 1 through a rubber sleeve 207;

[0029] It should be noted here that the rubber sleeve 207 is provided to provide sealing protection between the buffer ring 201 and the mounting end surface.

[0030] See also Figure 3 The damping assembly shown in the figure includes two U-shaped tubes 3 fixedly connected to the side wall of the buffer tube 203, and the two ends of the two U-shaped tubes 3 communicating with the buffer tube 203 are respectively located on both sides of the buffer plate 204, and the buffer tube 203 is filled with damping fluid. The two U-shaped tubes 3 are provided with a protection assembly for decelerating the buffer plate 204;

[0031] It should be noted here that: by setting the damping component, the damping fluid flows through the U-shaped tube 3, and since there are only two U-shaped tubes 3, resistance is formed on the flow of the damping fluid, further forming resistance buffer protection for the main body 1.

[0032] Working principle: When the angular displacement sensor is used, the body 1 is first connected to the buffer ring 201 by bolts, and then installed on the surface of the object to be detected, thereby achieving the installation and connection of the angular displacement sensor while ensuring the firmness of the installation of the angular displacement sensor;

[0033] After the angular displacement sensor is installed, when the body 1 is subjected to impact and vibration during use, the impact and vibration will push the buffer plate 204 at one end of the buffer rod 202 to move in the buffer tube 203. During the movement of the buffer plate 204, the first spring 205 will be deformed by the squeezing action of the buffer ring 201 to form an elastic force, thereby forming a first layer of buffer protection for the body 1 under the elastic force of the first spring 205.

[0034] And when the buffer plate 204 moves in the buffer tube 203, the damping liquid in the buffer tube 203 will be squeezed, so that the damping liquid will flow from the U-shaped tube 3. Since there are only two U-shaped tubes 3, resistance is formed to the flow of the damping liquid, and further resistance buffering protection is formed for the main body 1. Therefore, under the action of two layers of buffering protection, the impact and vibration to which the main body 1 is subjected during use are buffered and protected, thereby improving the impact and shock resistance of the main body 1, and further ensuring the measurement accuracy and service life of the angular displacement sensor.

[0035] Example 2

[0036] See also Figure 4 and Figure 5 This embodiment further explains Example 1. The protection assembly shown in the figure includes a first protection plate 401 fixedly connected to the U-shaped tube 3. The first protection plate 401 is connected to a second protection plate 402 via a rotating shaft on a side away from the buffer ring 201. The first protection plate 401 and the second protection plate 402 are provided with a plurality of protection holes 403. The U-shaped tube 3 is provided with a driving assembly for driving the second protection plate 402.

[0037] It should be noted here that: through the setting of the protective component, when the main body 1 is subjected to a large impact and vibration, the buffer plate 204 will receive a large extrusion driving force in the buffer tube 203. At this time, under the action of the driving component, the second protective plate 402 will be pushed to rotate. During the rotation of the second protective plate 402, the protective holes 403 on the second protective plate 402 will be staggered with the protective holes 403 on the first protective plate 401, thereby reducing the communication gap between the protective holes 403 on the first protective plate 401 and the second protective plate 402, making it more difficult for the damping fluid flowing on the U-tube 3 to pass through the protective holes 403, thereby increasing the damping effect, reducing the main body 1 from receiving a large impact and vibration, and reducing the probability of the buffer plate 204 contacting the bottom of the buffer tube 203, further improving the service life of the buffer component.

[0038] See also Figure 5The driving assembly shown in the figure includes two fixed rods 501 fixedly connected to the inner wall of the U-shaped tube 3 and symmetrically arranged. The two fixed rods 501 are slidably connected to the sliding plates 502. The opposite ends of the two sliding plates 502 are fixedly connected to the racks 503. One end of the rotating shaft passes through the second protective plate 402 and is fixedly connected to the gear 504. The gear 504 and the rack 503 are meshed with each other. The end of the rack 503 close to the buffer tube 203 is fixedly connected to the driving plate 505. The end of the driving plate 505 away from the rack 503 is located inside the buffer tube 203. The side of the buffer plate 204 close to the driving plate 505 is provided with an inclined surface 506. The side walls of the two fixed rods 501 are sleeved with second springs 507. The two ends of the second springs 507 are respectively connected to the inner wall of the U-shaped tube 3 and the sliding plate 502.

[0039] It should be noted here that: through the setting of the driving component, when the main body 1 is subjected to a large impact and vibration, the buffer plate 204 will receive a large extrusion driving force in the buffer tube 203. When the buffer plate 204 and the driving plate 505 are against each other, under the interaction force of the inclined surface 506 and the guiding action of the sliding plate 502 and the fixed rod 501, the rack 503 at one end of the driving plate 505 will be pushed to move in the U-shaped tube 3, thereby further utilizing the mutual meshing transmission action of the rack 503 and the gear 504 to drive the second protective plate 402 to rotate.
