Description

Technical Field

[0001] This application relates to the field of weighing module technology, specifically a weighing module connection structure. Background Technology

[0002] A weighing module is a new type of sensor application structure that can be easily connected to mechanical devices of various shapes, such as vertical tanks, troughs, and hoppers. By installing multiple load cells at the bottom of the supported component, such as the support feet of a hopper, it automatically measures the weight or level of the material inside the hopper. Because weighing modules require high precision, improper installation or use can lead to unstable connections or equipment damage, resulting in errors in the weighing data.

[0003] Chinese utility model patent CN 217637636 U discloses a weighing module connection structure. It employs a double-layer plate structure consisting of a base plate and a lower support plate. The lower support plate is pushed up using set screws and fixed by a first bolt on the base plate, achieving leveling and improving the connection accuracy with the equipment legs. However, in actual use, when adjusting the set screws to raise the corners of the lower support plate, a misalignment occurs between the lower support plate and the hole on the base plate for the first bolt. Frequent adjustment of the first bolt is required to accommodate this adjustment, which reduces connection stability and provides poor support for the lower support plate, potentially leading to loosening over long-term use.

[0004] Therefore, this application provides a weighing module connection structure to solve the above problems. Utility Model Content

[0005] This application provides a weighing module connection structure, which aims to solve the problems of poor connection stability of existing weighing module connection structures mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a weighing module connection structure, including a base plate, a lower support plate mounted on the base plate via a leveling mechanism, a cantilever load cell fixedly mounted on the lower support plate, and an upper support plate fixedly mounted on the weighing end of the cantilever load cell. The leveling mechanism includes a ball seat fixedly installed at the center of the base plate. A ball groove is formed within the ball seat, and a ball is rolled within the groove, with more than half of its volume located within the groove. A connecting plate is fixedly installed on the outer wall of the ball, protruding from the ball seat. The connecting plate is fixedly connected to the upper support plate. Adjusting rods, adapted to the four corners of the lower support plate, are movably installed on the base plate near the four corners. In use, after fixing the base plate to a level surface, the equipment's legs are placed against the upper support plate. Depending on the deviation, the four adjusting rods are adjusted. These rods push against the four corners of the lower support plate, causing the lower support plate to rotate in multiple directions within the ball groove via the ball on the connecting plate, thus adapting to the equipment's legs and quickly leveling the device. The ball seat in this application provides excellent anti-detachment locking of the ball, and the four adjusting rods do not deviate from their positions during longitudinal adjustment, eliminating the risk of misalignment. This ensures stable and reliable support during long-term use, preventing loosening.

[0007] Preferably, for quick adjustment of the support height, the adjusting rod includes a screw section and an adjusting nut fixedly installed at one end of the screw section. A tapered push rod is fixedly installed at the end of the adjusting nut away from the screw section. An adjusting screw hole adapted to the screw section is provided on the base plate. The end of the screw section away from the adjusting nut is screwed into the adjusting screw hole. The end of the push rod away from the adjusting nut abuts against the bottom of the lower support plate, thereby allowing the push rod to push the lower support plate to achieve an angled deflection, making the operation simple and convenient.

[0008] Preferably, in order to ensure the stability of the base plate installation, the base plate is provided with fixing holes near the four corners, and bolts independently set with the adjusting rods pass through the fixing holes to ensure that the base plate is stably installed on the horizontal ground and to ensure the overall stability of the equipment installation.

[0009] Preferably, in order to adapt to different equipment feet, the connection structure also includes a universal connection mechanism. The universal connection mechanism includes an adjustment groove on the upper support plate, in which a bidirectional lead screw is rotatably installed. One end of the bidirectional lead screw passes through the adjustment groove and a knob is fixedly installed at the end. Two mounting brackets for connecting equipment feet are symmetrically screwed onto the bidirectional lead screw, which effectively improves the versatility of the structure.

[0010] Preferably, for ease of connection, the mounting bracket includes two sliders symmetrically screwed onto a bidirectional lead screw, and a U-shaped support beam is fixedly mounted on each of the two sliders. The support beam has a mounting groove along its long side, making operation convenient and quick.

[0011] This connection structure, after fixing the base plate to a level ground, allows the equipment's legs to be attached to the upper support plate. Based on any deviation, four adjusting rods are adjusted. These rods push against the four corners of the lower support plate, causing the lower support plate to rotate in multiple directions within the ball groove via a ball on the connecting plate, thus adapting to the equipment's legs and quickly leveling it. The ball seat locking mechanism in this application provides excellent anti-detachment protection, and the four adjusting rods will not deviate from their positions in the longitudinal direction, eliminating the risk of misalignment. This ensures stable and reliable support during long-term use, preventing loosening.

[0012] This connection structure, based on the original dimensions of the equipment legs, allows for rotation of a knob, which in turn drives a bidirectional lead screw. The bidirectional lead screw causes two mounting brackets to move in opposite directions above the adjustment slot, thereby changing the distance between the two mounting brackets to fit the equipment legs and enable quick connection, effectively improving the versatility of the structure.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Example 1 This embodiment provides a weighing module connection structure, such as Figure 1-4As shown, the connecting structure includes a base plate 1, a lower support plate 3 mounted on the base plate 1 via a leveling mechanism 2, a cantilever load cell 4 fixedly mounted on the lower support plate 3, and an upper support plate 5 fixedly mounted on the weighing end of the cantilever load cell 4. The leveling mechanism 2 includes a ball seat 21 fixedly installed on the base plate 1 at the center position. A ball groove 22 is provided in the ball seat 21. A ball 23 is rolled in the ball groove 22. More than half of the volume of the ball 23 is located in the ball groove 22. A connecting plate 24 is fixedly installed on the outer side wall of the ball 23 protruding from the ball seat 21. The connecting plate 24 is fixedly connected to the upper support plate 5. Adjusting rods 25 adapted to the four corners of the lower support plate 3 are movably installed on the base plate 1 near the four corners.

[0017] In use, after fixing the base plate 1 on a level surface, attach the equipment's legs to the upper support plate 5. Adjust the four adjusting rods 25 according to the deviation. The four adjusting rods 25 push the four corners of the lower support plate 3 respectively, causing the lower support plate 3 to rotate in multiple directions within the ball groove 22 via the ball 23 on the connecting plate 24, thereby adapting to the equipment legs and quickly leveling it. The ball seat 21 in this application has a good anti-dislodgement effect by locking the ball 23, and the four adjusting rods 25 will not deviate from the hole position when adjusted longitudinally, eliminating the risk of misalignment. In subsequent long-term use, the support is stable and reliable, and it is not easy to loosen.

[0018] Specifically, the adjusting rod 25 includes a screw section 251 and an adjusting nut 252 fixedly installed at one end of the screw section 251. A tapered top rod 253 is fixedly installed on the end of the adjusting nut 252 away from the screw section 251. An adjusting screw hole 254 adapted to the screw section 251 is provided on the base plate 1. The end of the screw section 251 away from the adjusting nut 252 is screwed into the adjusting screw hole 254. The end of the top rod 253 away from the adjusting nut 252 abuts against the bottom of the lower support plate 3.

[0019] In use, a wrench is placed on the adjusting nut 252, and the screw section 251 is rotated to raise and lower the screw section 251 within the adjusting screw hole 254 to achieve height adjustment. This allows the push rod 253 to push the lower support plate 3 to achieve angle tilting, making the operation simple and convenient.

[0020] More specifically, the base plate 1 has fixing holes 11 near the four corners, and bolts 12, which are independently set with the adjusting rod 25, pass through the fixing holes 11.

[0021] In use, the base plate 1 is fixed on the horizontal ground by the independently set bolts 12 through the fixing holes 11, avoiding sharing the hole positions with the lower support plate 3. This ensures that the installation and adjustment between the base plate 1 and the lower support plate 3 do not affect each other, making the operation simple and ensuring that the base plate 1 is stably installed on the horizontal ground, thus guaranteeing the overall stability of the equipment installation.

[0022] Example 2 Unlike Embodiment 1, the prior art often uses a fixed-size upper support plate 5 to connect the equipment legs. However, the size of the equipment legs is often not fixed and it is difficult to fit the upper support plate 5. Usually, a transition plate needs to be cut and welded on the original equipment legs to connect with the upper support plate 5, which is inefficient and has poor structural versatility. Therefore, the connection structure also includes a universal connection mechanism 6. The universal connection mechanism 6 includes an adjustment groove 61 opened on the upper support plate 5. A bidirectional lead screw 62 is rotatably installed in the adjustment groove 61. One end of the bidirectional lead screw 62 passes through the adjustment groove 61 and a knob 63 is fixedly installed at the end. Two mounting brackets 64 for connecting the equipment legs are symmetrically screwed onto the bidirectional lead screw 62.

[0023] In use, according to the original size of the equipment legs, turn the knob 63 to drive the bidirectional lead screw 62 to rotate. The bidirectional lead screw 62 drives the two mounting brackets 64 to move in opposite directions above the adjustment groove 61, thereby changing the distance between the two mounting brackets 64 to adapt to the equipment legs, so as to make quick connection and effectively improve the versatility of the structure.

[0024] Specifically, the mounting bracket 64 includes two sliders 641 symmetrically screwed onto the bidirectional lead screw 62. A U-shaped support beam 642 is fixedly mounted on each of the two sliders 641. The support beam 642 has a mounting groove 643 along its long side.

[0025] In use, screws are inserted through the pre-drilled holes on the equipment legs and into the mounting slots 643 to secure the equipment to the mounting bracket 64, thus ensuring quick connection and convenient and fast operation.

[0026] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
