The pressure sensor with a support structure is a specially designed pressure sensor, which adds one or more support structures on the basis of the traditional pressure sensor to improve its stability and reliability in various working environments.

[0003] At present, when the existing pressure sensors provided with support structures are subjected to external impact or vibration, the impact resistance of the pressure sensors cannot be effectively improved, resulting in measurement errors or even damage. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art that the impact resistance of the pressure sensor cannot be effectively improved, resulting in measurement errors or even damage, and to propose a pressure sensor with a support structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pressure sensor provided with a support structure, comprising:

[0007] Ring frame 1 and pressure sensor body, a connecting seat is fixedly arranged on the top of the ring frame 1, a common through hole is opened on the ring frame 1 and the connecting seat, and a ring frame 2 is hingedly arranged on one side of the ring frame 1;

[0008] A support assembly, which is arranged on the ring frame 1 and is used to support and fix the pressure sensor body;

[0009] The buffer component is arranged on the supporting component and is used to alleviate the influence of external shock or vibration on the pressure sensor body.

[0010] In a possible design, the support assembly includes two fixed seats symmetrically fixed on the top of a ring frame, the inner sides of the two fixed seats are hinged with support rods, the interiors of the two support rods are provided with cavities, and sliding rods are slidably arranged in the cavities, the other ends of the two sliding rods are hinged with fixed seats 2, and the sides of the two fixed seats 2 close to each other are fixed with clamping frames.

[0011] In a possible design, the buffer assembly includes dampers respectively fixedly arranged inside the cavities of the two struts, and the piston ends of the two dampers are fixedly provided with limit blocks, and the two limit blocks are respectively fixedly connected to one end of the two sliding rods located in the cavity, and the outside of the two sliding rods is provided with a spring, one end of the spring is fixedly connected to the limit block, and the other end of the spring is fixedly connected to the inner wall of the strut cavity.

[0012] In a possible design, the top of the connecting seat is rectangular and movably provided with four connecting rods, and the adjacent ends of the four connecting rods are hingedly provided with a same mounting seat, and the pressure sensor body is threadedly connected to the mounting seat.

[0013] In a possible design, buckle blocks are fixedly provided on both sides of one of the clamping frames, and buckle frames are fixedly provided on both sides of the other clamping frame. Buckle grooves are provided on one side of the two buckle frames, and the buckle blocks are adapted to the buckle grooves and can be disengaged.

[0014] In a possible design, a screw rod is rotatably provided on one side of the ring frame 1, an external thread of the screw rod is connected with a butterfly knob, and a bayonet is provided on a corresponding side of the ring frame 2.

[0015] In a possible design, a rubber anti-slip pad is fixedly provided on one side of the inner wall of the ring frame 1 and the ring frame 2.

[0016] In this application, when starting to use, first check whether all parts are intact and perform necessary cleaning work, then install the entire device on the required position or equipment through ring frame one and ring frame two, then rotate the screw rod, the screw rod rotates into the bayonet of the column ring frame two, then rotate the butterfly knob, the butterfly knob rotates on the outside of the screw rod until it abuts against the ring frame two to complete the fixation of the entire device, then pass the pressure sensor body through the mounting seat, the connecting seat and the ring frame one, so that the contact end of the pressure sensor body is located on the inner side of the ring frame one and abuts against the equipment that needs to detect pressure, then the pressure sensor body is installed on the mounting seat through the external thread on the pressure sensor body and the internal thread on the mounting seat for threaded connection, then move the two clamping frames to the side close to each other, so that the ends of the two clamping frames with openings are wrapped around the outside of the pressure sensor body, in the process of the two clamping frames wrapping around the pressure sensor body, the buckle frame on one of the clamping frames approaches the buckle block and slides over the buckle block, so that the buckle groove on it is engaged with the buckle block, completing the fixed support of the pressure sensor body, and then the pressure sensor body is connected to the external equipment through the plug;

[0017] When external force acts on the pressure sensor body, the slide bar slides in the support rod, and the damper generates a damping force. The damping force can effectively slow down the movement speed of the slide bar, thereby absorbing and dissipating part of the impact energy. At the same time, the spring generates a reaction force when the slide bar moves through its own elastic principle, further slowing down the movement speed of the slide bar and absorbing the remaining impact energy. The elastic restoring force of the spring can also help the slide bar to quickly return to its original position after the external force disappears, ensuring that the clamping frame stably clamps the pressure sensor body, thereby utilizing the dual buffering mechanism of damping force and elasticity to enable the pressure sensor body to maintain stable measurement performance in a complex working environment and avoid measurement errors or damage caused by external shocks or vibrations.

[0018] The utility model has the following beneficial effects:

[0019] In the utility model, a stable support system is formed by setting the support assembly, the hinged structure formed by the fixed seat, the support rod and the slide rod, and the tight clamping of the clamping frame, so as to realize the stable support and effective clamping of the pressure sensor body, ensure that the sensor can maintain a stable working state in both static and dynamic environments, and provide a certain damping effect to prevent the sensor body from large displacement or shaking, thereby improving the measurement accuracy and service life of the sensor;

[0020] In the utility model, by setting the buffer component, when the external force acts on the pressure sensor body, the slide bar slides in the support rod, and the damping force generated by the damper cooperates with the elastic reaction force of the spring to effectively slow down the movement speed of the slide bar, absorb and dissipate the impact energy, and use the double buffer mechanism to not only improve the impact resistance of the sensor, but also quickly restore the stable clamping state after the external force disappears, ensuring that the sensor maintains accurate measurement performance in a complex working environment, and effectively avoiding damage to the measurement accuracy and the sensor itself caused by external shock or vibration;

[0021] The utility model effectively improves the impact resistance of the pressure sensor by setting the buffer component, ensures its accurate measurement performance in a complex working environment, and prevents external impact or vibration from causing damage to the sensor.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Embodiment 1

[0029] Reference Figure 1-4 , a pressure sensor comprising:

[0030] Ring frame 1, a connecting seat 2 is fixedly installed on the top of the ring frame 1, ensuring that the ring frame 1 and the connecting seat 2 have aligned and common holes, so as to facilitate the subsequent installation of the pressure sensor body 3 (brand model: MWACON / SUP-P300). Ring frame 2 101 is hingedly installed on one side of the ring frame 1, and the two can be flexibly opened and closed.

[0031] The support assembly includes two fixed seats 4 fixedly installed in symmetrical positions on the top of the ring frame 1, and a support rod 5 is hingedly installed on the inner side of each fixed seat 4 to ensure that the support rod 5 can rotate freely. A cavity is opened inside the support rod 5, and a slide rod 6 is slidably installed in the cavity. A fixed seat 2 7 is hingedly installed on the other end of the slide rod 6, and a clamping frame 8 is fixedly installed on the side where the two fixed seats 2 7 are close to each other. An opening matching the outer side of the pressure sensor body 3 should be opened on the inner side of the clamping frame 8 so as to clamp tightly, thereby achieving stable support and effective clamping of the pressure sensor body 3.

[0032] The buffer assembly includes a damper 501 fixedly installed inside the cavity of each support rod 5, and the piston end of each damper 501 is fixedly connected to a limit block 601. The limit block 601 is fixedly connected to one end of the slide rod 6 located in the cavity. A spring 602 is sleeved on the outside of the slide rod 6 to ensure that one end of the spring 602 is fixedly connected to the limit block 601, and the other end is fixedly connected to the inner wall of the cavity of the support rod 5. When an external force acts on the pressure sensor body 3, the slide rod 6 slides in the support rod 5, and the damper 501 generates a damping force. The damping force can effectively slow down the movement speed of the slide rod 6, thereby absorbing and dissipating part of the impact energy. At the same time, the spring 602 generates a reaction force when the slide rod 6 moves through its own elastic principle, further slowing down the movement speed of the slide rod 6 and absorbing the remaining impact energy. The elastic restoring force of the spring 602 can also help the slide rod 6 to quickly return to its original position after the external force disappears, thereby ensuring that the clamping frame 8 stably clamps the pressure sensor body 3.

[0033] The top of the connecting seat 2 is rectangular and has four connecting rods 201 movably installed thereon. The four connecting rods 201 are hingedly provided with the same mounting seat 202 at one end close to each other. The pressure sensor body 3 is fixed to the mounting seat 202 by threaded connection, thereby facilitating the installation and disassembly of the pressure sensor body 3, and facilitating the replacement and maintenance of the pressure sensor body 3.

[0034] Buckle blocks 801 are fixedly installed on both sides of one of the clamping frames 8, and buckle frames 802 are fixedly installed on both sides of the other clamping frames 8, and a buckle groove is opened on one side of the buckle frame 802 to ensure that the buckle block 801 is compatible with the buckle groove and can be disengaged when necessary, so as to install or remove the pressure sensor body 3 and facilitate the replacement and maintenance of the pressure sensor body 3.

[0035] The present application may be used in the technical field of pressure sensors provided with a support structure, and may also be used in other fields applicable to the present application.

[0036] Embodiment 2

By rotating the butterfly knob 11, the ring frame 1 and the ring frame 2 101 can be locked or loosened, which is convenient for the installation between the overall device and the equipment.

[0038] A rubber anti-skid pad 12 is fixedly installed on one side of the inner wall of the ring frame 1 and the ring frame 2 101, which can increase the friction between the ring frame 1 and the ring frame 2 101 and the pressure equipment to be tested to prevent the device from sliding or shifting during use.
