Description

Technical Field

[0001] The invention relates to the technical field of tension sensors, in particular to a tension pressure sensor. Background Art

[0002] Tension and pressure sensors are extremely important measuring devices, mainly used to accurately measure the tension or pressure on an object. Tension and pressure sensors have many remarkable characteristics, such as extremely high precision, strong reliability, and extremely fast response speed. They are widely used in many different fields. In the field of industrial production, they can be used to closely monitor the operating status of mechanical equipment, accurately measure the size of various forces, and effectively ensure the safety and stability of the production process; in the weighing system, they can measure the weight of objects very accurately; in the field of scientific research experiments, they can be used for material mechanical properties testing, etc. It can provide accurate force measurement data for many fields such as production, scientific research, and engineering, and plays a vital role in ensuring the normal operation of equipment, improving product quality, and promoting scientific research.

[0003] However, when using a tension and pressure sensor, the connection block needs to be fixed on the object being used. After the sensor tests the tension and pressure, the tested tension and pressure are transmitted to the display through the wire. However, when the sensor is installed outdoors, problems will arise. The wires exposed outdoors will be constantly pulled by the wind. After the connection between the wire and the sensor is pulled many times, it is easy to fall off, which will cause the sensor to fail to work properly.

[0004] In order to solve the above technical problems, a Chinese patent with the announcement number "CN221350349U" in the prior art discloses a column-type tension and pressure sensor, which includes a sensor body, a connecting block, a wire, a fixing device, a fixing column, a spring, a slider, a first clamping plate, a second clamping plate and a screw rod. Although the above device solves the problem that when the sensor is installed outdoors, the connection between the wire and the sensor is easily pulled off by wind force, resulting in the sensor being unusable, it still has some shortcomings;

[0005] Although the above device uses an elastic structure to assist in positioning the wires, it has obvious disadvantages. The excess part of the wires will drag on the outside of the sensor. During actual use, such messy wires are very likely to get tangled. Once tangled, the wires may break over time and under the influence of external factors. This will undoubtedly seriously affect the subsequent use of the sensor as a whole and bring great inconvenience to practical applications. At the same time, the sensor cannot be adaptively rotated according to specific needs during the application process. During actual application, it can only be used at a single angle. However, in a wide range of application scenarios, sensors may usually face tension detection requirements at different angles. For example, in a complex industrial production environment, the direction of the tension may come from various different angles; in scientific research experiments, it may also be necessary to measure the force from different angles to obtain more comprehensive data. It can be seen that this sensor that can only be used at a single angle has certain defects and shortcomings in practical applications. Summary of the invention

[0010] Furthermore, the mounting assembly includes a bottom rail and a mounting block, the bottom rail is fixedly mounted on each outer surface of the bottom of the hexagonal mounting column, the bottom of the bottom rail is slidably connected with a rectangular sliding plate, the bottom of the rectangular sliding plate is fixedly mounted with a limiting card frame, the top of the rectangular sliding plate is fixedly connected with a guide plate, the top of the guide plate and the bottom of the guide frame are fit-connected, the mounting block is inserted between the inner sides of the limiting card frame, and the bottom of the mounting block is fixedly connected to the top of the tension and pressure sensor body.

[0011] Furthermore, a first guiding bevel is provided at the inner lower end of the guide frame, a second guiding bevel is provided at the top outer side of the guide plate, and the first guiding bevel and the second guiding bevel are fitted and connected.

[0012] Furthermore, a third guiding inclined surface is provided at the bottom of the position-limiting clamping frame, the upper end of the mounting block is configured in a cone shape as a whole, and the overall cross-sectional shape of the position-limiting clamping frame is configured in a hook shape.

[0013] Furthermore, the angle detection mechanism includes a circular plate, which is fixedly mounted on the top of the mounting ball, the top of the circular plate is rotatably connected to a rotating coupling, and the top of the rotating coupling is fixedly connected to a horizontal measuring ruler.

[0014] Furthermore, a connecting block is fixedly connected to one side of the bottom of the level measuring ruler, and a weight-bearing ball is fixedly connected to the bottom of the connecting block.

[0015] Furthermore, the line winding mechanism includes a vertical rail, which is fixedly installed on one side of the bottom of the mounting plate. A slide is slidably connected to the inside of the vertical rail, a torsion spring is fixedly installed on the inner side of the slide, a winding wheel is fixedly connected to the front side of the torsion spring, an insertion hole is opened in the middle of the winding wheel, and the line of the tension and pressure sensor is passed through the inside of the insertion hole.

[0016] Furthermore, a support shaft is fixedly installed on the rear side of the winding wheel, a rear end of the support shaft passes through the slide and a crank is fixedly installed thereon, and the support shaft and the slide are rotatably connected.

[0017] Furthermore, the inner and outer ends of the bottom rail are fixedly connected with a return spring, the inner end of the return spring is fixedly connected to the outer side of the rectangular sliding plate, the outer side of the guide frame is fixedly connected with a handrail ring, and the handrail ring is slidably connected to the outer side of the hexagonal mounting column.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] First, in the present invention, the mounting block is inserted into the inner side of the limit clamping frame from bottom to top, and the conical surface at the top of the mounting block contacts the third guiding inclined surface at the bottom of the limit clamping frame, so that the mounting block is pushed open to open the limit clamping frame. After the mounting block is inserted into place, the limit spring is reset to make the rectangular sliding plate drive the curved hook-shaped limit clamping frame to fit and limit with the bottom of the mounting block, so as to complete the installation of the tension pressure sensor body. During use, the curved hook-shaped limit clamping frame stably bites the mounting block, and even if the sensor is pulled, the stability of the mounting block can be ensured. When removing, the limit handrail ring is lifted, the guide frame moves up and separates from the guide plate, and the reset spring drives the rectangular sliding plate and the limit clamping frame to move outward, so that the mounting block can be removed. This mounting mechanism realizes the rapid disassembly and maintenance of the sensor body, which greatly improves the overall convenience of the device.

[0020] Secondly, the device has outstanding performance after the installation ball is set. The device can be installed to the desired position through the installation plate. The bottom of the installation frame adopts the installation ball to assist the hinged installation mechanism. When the tension sensor detects that the tension direction changes, the installation ring cooperates with the design of the hinged ring so that the hinged ball can rotate and adapt flexibly, so that the sensor can adapt to tension detection in different directions. At the same time, an angle detection mechanism is set. The rotation of the installation ball drives the rotating coupling body to tilt. The horizontal measuring ruler is pulled by the weight-bearing ball to rotate adaptively and can be adjusted according to the rotation direction of the installation ball. On the one hand, the device can flexibly adapt to tension detection in different directions and angles. On the other hand, it can quickly detect the tilt angle during the sensor detection. The overall application is convenient and the adaptability is strong.

[0021] Third, during use, after passing the wire through the insertion hole, release the crank handle, the torsion spring resets and the winding wheel rotates to wrap the wire around the outer surface. During use, the direction of the sensor body changes and the wire is pulled. The winding wheel is naturally pulled and rotated due to the positioning of the torsion spring. After use, the torsion spring resets and drives the winding wheel to reset and rotate to rewind the wire. When the wire is wound and loosened, the slide frame slides up and down adaptively in the vertical rail, so that the wire has strong stability and neat layout, which further improves the stability of the sensor body and facilitates the use of the sensor. This mechanism can automatically reset the wound wire to avoid wire entanglement or breakage, so that the wire remains stable during use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] See also Figure 1-Figure 8 In an embodiment of the present invention, a tension pressure sensor includes a mounting plate 1, a mounting plate 2 is fixedly mounted on the bottom of the mounting plate 1, a mounting frame 3 is fixedly mounted on the bottom of the mounting plate 2, a hinge ring 4 is fixedly mounted on the inner lower end of the mounting frame 3, a mounting ball 5 is rotatably connected to the inner side of the hinge ring 4, a mounting mechanism 6 is fixedly mounted on the bottom of the mounting ball 5, a tension pressure sensor body 7 is mounted on the bottom of the mounting ball 5 through the mounting mechanism 6, a line winding mechanism 8 is fixedly mounted on one side of the bottom of the mounting plate 1, a line of the tension pressure sensor is wound around the inner side of the line winding mechanism 8, and an angle detection mechanism 9 is fixedly mounted on the top of the mounting ball 5;

[0032] The mounting mechanism 6 includes a hexagonal mounting column 61, which is fixedly mounted on the bottom of the mounting ball 5. Elastic components 62 are movably mounted on each outer surface of the hexagonal mounting column 61. A mounting component 63 is fixedly mounted on the bottom of the hexagonal mounting column 61. The top of the mounting component 63 and the bottom of the elastic component 62 are fitted and connected. The bottom of the hexagonal mounting column 61 is installed with a tension and pressure sensor body 7 through the mounting component 63. The mounting plate 2 and the mounting frame 3 at the bottom of the mounting plate 1 provide a stable support structure for the entire device. The hinge ring 4 at the lower inner end of the mounting frame 3 cooperates with the mounting ball 5, so that the tension and pressure sensor can be flexibly rotated to adapt to different directions. For tension detection, the hexagonal mounting column 61, the elastic component 62 and the mounting component 63 in the mounting mechanism 6 can stably install the tension pressure sensor body 7, and it is easy to install and disassemble, which improves the convenience of use. The line winding mechanism 8 can neatly wrap the line of the tension pressure sensor body 7 on the inside to avoid line entanglement or breakage, thereby ensuring stability and safety during use. The angle detection mechanism 9 on the top of the mounting ball 5 can detect the tilt angle of the sensor in real time, providing more data support for accurate measurement. The overall design is exquisite and fully functional, which greatly improves the practicability and reliability of the tension pressure sensor body 7.

[0033] See also Figure 1-Figure 5 and Figure 6-Figure 7The elastic component 62 includes a slide groove 621, which is opened in the middle of each outer surface of the hexagonal mounting column 61. The top of the slide groove 621 is fixedly connected to a limit spring 622, and the bottom of the limit spring 622 is fixedly connected to a guide frame 623. The bottom of the guide frame 623 is fitted and connected with the top of the mounting component 63. The mounting component 63 includes a bottom rail 632 and a mounting block 631. The bottom rail 632 is fixedly installed on each outer surface of the bottom of the hexagonal mounting column 61. The inside of the bottom rail 632 is slidably connected with a rectangular sliding plate 633. The bottom of the rectangular sliding plate 633 is fixedly installed with a limit clamping frame 634, and the top of the rectangular sliding plate 633 is fixedly connected with a guide plate 635 The top of the guide plate 635 and the bottom of the guide frame 623 are fitted and connected, the mounting block 631 is inserted between the inner sides of the limit clamping frame 634, the bottom of the mounting block 631 and the top of the tension and pressure sensor body 7 are fixedly connected, the lower inner end of the guide frame 623 is provided with a first guide slope 625, the outer top of the guide plate 635 is provided with a second guide slope 637, the first guide slope 625 and the second guide slope 637 are fitted and connected, the bottom of the limit clamping frame 634 is provided with a third guide slope 638, the upper end of the mounting block 631 is generally conical, the overall cross-sectional shape of the limit clamping frame 634 is hook-shaped, and the sliding groove on the outer side of the hexagonal mounting column 61 621 provides an installation position for the elastic component 62, wherein the limit spring 622 and the guide frame 623 cooperate to play a buffering and guiding role during the installation and removal process. The combination of the bottom rail 632 and the rectangular sliding plate 633 in the installation component 63 allows the limit clamping frame 634 to move flexibly. When the installation block 631 is inserted into the inner side of the limit clamping frame 634, the conical design on the top of the installation block 631 interacts with the third guiding slope 638 at the bottom of the limit clamping frame 634, which can easily open the limit clamping frame 634, causing the rectangular sliding plate 633 to slide, and drive the guide frame through the fitting connection of the first guiding slope 625 and the second guiding slope 637. 623 moves the compression limit spring 622. After the installation is completed, the limit spring 622 is reset, and the hook-shaped limit clip frame 634 fits tightly with the mounting block 631 to ensure that the tension pressure sensor body 7 is firmly installed. This design not only facilitates the rapid installation and disassembly of the sensor body and improves the convenience of use, but also ensures the stability of the sensor body during use, and it is not easy to loosen even if it is pulled by external force. The setting of the third guide bevel 638 can assist in guiding during the installation of the mounting block 631. The contact between the third guide bevel 638 and the conical surface can help to open the limit clip frame 634, making it convenient for the device to be quickly installed and used during application.

[0034] See also Figure 1-Figure 4 and Figure 8The angle detection mechanism 9 includes a circular plate 91, which is fixedly installed on the top of the mounting ball 5. The top of the circular plate 91 is rotatably connected with a rotating coupling body 92, and the top of the rotating coupling body 92 is fixedly connected with a horizontal measuring ruler 93. A connecting block 94 is fixedly connected to one side of the bottom of the horizontal measuring ruler 93, and a weight-bearing ball 95 is fixedly connected to the bottom of the connecting block 94. The circular plate 91 is fixed to the top of the mounting ball 5, providing a stable installation foundation for the rotating coupling body 92. The rotating coupling body 92 enables the horizontal measuring ruler 93 on the top to rotate flexibly. When the detection direction of the tension and pressure sensor changes during use, the mounting ball 5 rotates, which will drive the rotating coupling body 92 on the top of the circular plate 91 to tilt. At this time, due to the rotation design of the rotating coupling body 92, the connecting block 94 and the weight-bearing ball 95 on one side of the bottom of the horizontal measuring ruler 93 will play a key role under the action of gravity. The weight-bearing ball 95 is affected by gravity and can pull the horizontal measuring ruler 93 along with the rotation during the process of the mounting ball 5 adapting to the detection direction. The movable coupling 92 rotates adaptively. When the tension at different positions is detected, the mounting ball 5 will adaptively rotate away from the adjustment direction. During this period, as the mounting ball 5 rotates, the rotating coupling 92 and the horizontal measuring ruler 93 on the top circular plate 91 will also rotate and change. At this time, as the horizontal measuring ruler 93 rotates, the horizontal measuring ruler 93 itself is designed to be connected by rotating the rotating coupling 92. During the rotation of the horizontal measuring ruler 93, since the load-bearing ball 95 is affected by the gravity of the earth, its gravity is always downward. Therefore, the horizontal weighing ruler will be affected by gravity to adaptively change its position according to the inclination direction of the tension and pressure sensor body 7. It can be seen that in this way, the horizontal measuring ruler 93 can be adaptively adjusted according to the different rotation directions of the mounting ball 5. On the one hand, it can quickly detect the inclination angle during the detection of the tension and pressure sensor, providing an important reference for accurate measurement. On the other hand, it makes the entire device more convenient and more adaptable during use.

[0035] See also Figure 1-Figure 5The line winding mechanism 8 includes a vertical rail 81, which is fixedly installed on one side of the bottom of the mounting plate 1. The vertical rail 81 is slidably connected to a slide 82 inside the vertical rail 81, and a torsion spring 83 is fixedly installed on the inner side of the slide 82. A winding wheel 84 is fixedly connected to the front side of the torsion spring 83. An insertion hole 85 is opened in the middle of the winding wheel 84. The line of the tension pressure sensor is inserted into the insertion hole 85. A support shaft 86 is fixedly installed on the rear side of the winding wheel 84. The rear end of the support shaft 86 passes through the slide 82 and is fixedly installed with a crank 87. The support shaft 86 and the slide 82 are rotatably connected. The inner and outer ends of the bottom rail 632 are fixedly connected to a reset spring 636. The inner end of the reset spring 636 and the outer end of the rectangular sliding plate 633 are fixedly connected. The side is fixedly connected, the elastic force of the limit spring 622 is more than twice the elastic force of the reset spring 636, the outer side of the guide frame 623 is fixedly connected with an armrest ring 624, and the armrest ring 624 is slidably connected to the outer side of the hexagonal mounting column 61. The vertical rail 81 provides a stable sliding track for the slide 82 to ensure that the slide 82 can slide up and down smoothly inside it. The torsion spring 83 on the inside of the slide 82 is connected to the winding wheel 84. After the tension pressure sensor body 7 is installed, the sensor line can be passed through the insertion hole 85 in the middle of the winding wheel 84. After the installation is completed, release the crank 87, and the torsion spring 83 is reset to drive the winding wheel 84 to rotate, and the wire is wound around the outer surface of the winding wheel 84. During use, When the direction of the sensor body changes and the wire is pulled, since the take-up wheel 84 is positioned by the torsion spring 83, the wire will naturally pull the take-up wheel 84 to rotate, avoiding the wire from being entangled or accidentally broken, so that the wire can remain in a relatively stable state during use. The torsion spring 83 provides elastic force to drive the take-up wheel 84 to rotate, so that no matter the wire is pulled or loosened, the take-up wheel 84 will rotate adaptively, which can keep the wire in a taut state at all times and avoid the guide from being dragged and loosened, thus avoiding the normal use of the guide flip cover tension sensor to the greatest extent, and further reducing the probability of wire entanglement or breakage, and the inner and outer sides of the bottom rail 632 are The reset spring 636 at the end can assist the movement of the rectangular sliding plate 633 during the installation and disassembly process, and facilitates the cooperation between the installation block 631 and the limiting clamping frame 634. The reset spring 636 can provide elastic force to prompt the rectangular sliding plate 633 to reset, and the elastic force of the reset spring 636 is smaller than that of the limiting spring 622, so it does not affect the limiting force of the limiting spring 622. The installation block 631 is conical, and the limiting clamping frame 634 at the bottom is hook-shaped, which can hook the installation block 631 more stably, so that the installation block 631 as a whole can have strong installation stability after installation. The handrail ring 624 on the outside of the guide frame 623 is easy to operate, and the sensor can be quickly disassembled and assembled.

[0036] The working principle of the present invention is: by carefully setting the installation mechanism 6, the present device exhibits many advantages during actual use. Specifically, the installation block 631 can be inserted between the inner sides of the limiting clamping frame 634 from bottom to top. During this process, the top conical surface of the installation block 631 will contact the third guiding inclined surface 638 at the bottom of the limiting clamping frame 634. With the guiding effect of the installation block 631 and the third guiding inclined surface 638, the installation block 631 can be urged to open each limiting clamping frame 634. After the limiting clamping frame 634 is opened, it will push the rectangular sliding plate 633 to slide toward the outside. When the rectangular sliding plate 633 moves outward, the mutual guidance of the first guiding inclined surface 625 and the second guiding inclined surface 637 can drive the guide frame 623 to move up and compress the limit spring 622. When the mounting block 631 is successfully inserted between the inner sides of each limit clamping frame 634, the limit spring 622 is reset, thereby driving the guide frame 623 to contact the guide plate 635. Since the second inclined surface of the guide plate 635 and the first inclined surface of the guide frame 623 guide each other, the rectangular sliding plate 633 can drive the limit clamping frame 634 to move inward. During this period, the limit clamping frame 634 set in a hook shape will contact with the limit clamping frame 634. The bottoms of the mounting blocks 631 are mutually fitted and limited, and at this time, the mounting blocks 631 can be firmly installed on the inner side of the limit clamping frame 634. Since the tension pressure sensor body 7 is installed on the bottom of the mounting block 631, the installation of the tension pressure sensor body 7 is completed at this time. Moreover, when the tension pressure sensor is pulled during use, the limit clamping frame 634 with a curved hook shape can bite the mounting block 631 more stably, so that the mounting block 631 as a whole can be stably located on the inner side of the limit clamping frame 634. It can be seen that the tension pressure sensor body 7 can be relatively stably located in the limit The inner side of the clamping frame 634, and if the tension pressure sensor needs to be removed, the limit armrest ring 624 can be pulled upward, and the armrest ring 624 drives the guide frame 623 to move upward. At this time, the guide frame 623 and the guide plate 635 are separated, and the reset spring 636 is extended and reset to drive the rectangular sliding plate 633 to move outward, and the rectangular sliding plate 633 drives the limit clamping frame 634 to move outward. At this time, the installation block 631 can be removed from the inner side of the limit clamping frame 634. It can be seen that the tension pressure sensor body 7 of the device can be quickly disassembled and maintained as a whole, which greatly improves the overall convenience of use of the device;

[0037] By providing the mounting ball 5, the device has outstanding performance during use, and the device can be installed as a whole to the desired position through the mounting plate 1. During use, since the mounting ball 5 is used at the bottom of the mounting frame 3 to assist the hinged mounting mechanism 6, during the use of the tension and pressure sensor, when the direction of the tension detected by it changes, due to the installation design of the mounting ring in conjunction with the hinged ring 4, when the direction changes, the hinged ball can be flexibly rotated and adapted adaptively, which makes the sensor as a whole able to adapt to tension detection in different directions, and during its use, since the angle detection mechanism 9 is provided, during the rotation of the mounting ball 5, the mounting ball 5 will drive the rotating coupling body 9 at the top of the circular plate 91 2. Tilt. Since the rotating coupling body 92 is arranged to rotate, when the rotating coupling body 92 tilts, the horizontal measuring ruler 93 at the rotating top will be pulled by the weight-bearing ball 95 outside the connecting block 94 and rotate adaptively. The weight-bearing ball 95 is affected by gravity, and can make the articulated ball drive the horizontal measuring ruler 93 to rotate during the process of the installation ball 5 adapting to the detection direction. At this time, the horizontal measuring ruler 93 can be adaptively adjusted according to the different rotation directions of the installation ball 5. On the one hand, the device as a whole can flexibly adapt to the tension detection in different directions and angles; on the other hand, in the overall detection process, the tilt angle during the detection of the tension and pressure sensor can be quickly detected, and the overall application is more convenient and the adaptability is stronger.

[0038] By setting up the line winding mechanism 8, the device performs well during use. First, after the tension pressure sensor body 7 is installed, the crank 87 is pulled to rotate. The rotation of the crank 87 can drive the support shaft 86 to rotate. The rotation of the support shaft 86 can drive the winding wheel 84 to rotate, and the wire of the tension pressure sensor body 7 is passed through the insertion hole 85. At this time, the wire passes through the insertion hole 85. After the installation of the tension pressure sensor body 7 is completed, the crank 87 is released, and the torsion spring 83 is reset to drive the winding wheel 84 to rotate. At this time, the winding wheel 84 rotates to connect the wire to the outer surface of the winding wheel 84. During use, when the direction of the tension pressure sensor body 7 changes, the wire is pulled. At this time, since the winding wheel 84 is positioned by the torsion spring 83, the wire When pulled, the winding wheel 84 will naturally rotate. After the tension pressure sensor body 7 is used, the torsion spring 83 will adaptively reset to drive the winding wheel 84 to reset and rotate, thereby rewinding the wire. It can be seen that the device as a whole can automatically reset the wound wire during the use of the tension pressure sensor body 7, which can avoid the wire from being entangled or accidentally broken, and can enable the wire as a whole to be in a relatively stable state during use. Moreover, during its use, when the wire is wound and relaxed, the slide frame can adaptively slide up and down inside the vertical rail 81, so that the wire of the device as a whole can have strong stability and neat layout, further improving the stability of the tension sensor body as a whole and facilitating the use of the sensor.
