[0022] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0023] like Figure 1 As shown, this utility model provides an I-beam weighing module, and some specific embodiments are described below. To overcome the above-mentioned technical problems, according to the embodiments of this utility model, an I-beam weighing module is provided, including a lower plate assembly 1, a weighing sensor 2, and a pressure plate assembly 3. The weighing sensor 2 is installed inside the lower plate assembly 1, and the pressure plate assembly 3 is located above the lower plate assembly 1 and presses against the weighing sensor 2.

[0024] like Figures 1-3 As shown, in some embodiments, the lower plate assembly 1 specifically includes a base plate 101, a support plate 102 welded to the upper side of the base plate 101, and a working plate 103 welded to the top of the support plate 102. The support plate 102 includes two plates arranged side by side with a gap between them. The working plate 103 is arranged parallel to the base plate 101, and the width of the working plate 103 is greater than the maximum gap between the two support plates 102. The area enclosed by the support plate 102, the base plate 101, and the working plate 103 constitutes an installation space 105, and the load-bearing part of the load cell 2 is located inside the installation space 105. The front opening of the installation space 105 is a first installation opening 104.

[0025] Preferably, the two support plates 102 are arranged opposite each other. Specifically, the support plates 102 are made of two pieces of thick steel welded together to form the front and rear openings of the installation space 105, with balanced and strong support forces on both sides. The width of the working plate 103 is greater than the maximum distance between the two support plates 102, so that the support plates 102, the base plate 101 and the working plate 103 form an approximate I-shaped structure to improve structural strength and stability.

[0026] A through hole 106 is provided on the working plate 103, located directly above the mounting space 105. The through hole 106 intersects with the side of the working plate 103 facing the working plate 103 to form a clearance notch 107, thus creating a mounting opening on the side of the mounting space 105. The load cell 2 can enter the mounting space 105 through the clearance notch 107 and be fixed to the base plate 101. Due to the presence of the first mounting opening 104 and the clearance notch 107, the installation and maintenance of the load cell 2 are very convenient.

[0027] The pressure plate assembly 3 includes an upper pressure plate 301 and an upper pressure head 302 detachably connected to the lower side of the upper pressure plate 301. The upper pressure head 302 is located above the through hole 106. The upper pressure head 302 is installed in such a way that the bottom of the upper pressure plate 301 has a mounting groove 304, and the top bolt of the upper pressure head 302 is in the mounting groove 304.

[0028] The upper pressure head 302 has an upper pressure groove 303 at its bottom. The weighing end of the load cell 2 passes through the through hole 106 into the upper pressure groove 303, so that the weight borne by the upper pressure plate 301 is transferred to the load cell 2 through the upper pressure head 302, thereby reading the specific weight value of the equipment connected above the upper pressure plate 301. Since the weighing end of the load cell 2 needs to pass through the through hole 106, and the clearance notch 107 opened on the side of the through hole 106 in this application allows the load cell 2 to be installed from the side instead of below the through hole 106, which provides more operating space and better convenience.

[0029] To prevent the pressure plate assembly 3 from tipping over, a limiting component 4 is installed between the pressure plate assembly 3 and the working plate 103. Specifically, the limiting component 4 includes a limiting rod 401 and a limiting sleeve 402. The limiting sleeve 402 is installed on the working plate 103, specifically by creating a hole in the working plate 103 and then fixing the limiting sleeve 402 inside the hole. The limiting rod 401 is inverted T-shaped, with its lower diameter larger than its upper diameter. The upper end of the limiting rod 401 passes through the limiting sleeve 402 and connects to the upper pressure plate 301. The lower diameter of the limiting rod 401 is larger than the inner diameter of the limiting sleeve 402. The inner diameter of the limiting sleeve 402 is 2-5 mm larger than the upper diameter of the limiting rod 401, so that when the upper pressure plate 301 is subjected to pressure and moves downward, the limiting rod 401 moves downward within the limiting sleeve 402 without affecting the weighing.

[0030] There are two limiting components 4, located on both sides of the through hole 106. Preferably, the limiting components 4 are centrally and symmetrically distributed on the working plate 103. When the upper pressure plate 301 tilts significantly, one side of the upper pressure plate 301 tilts up, and the limiting rod 401 on that side moves upward. Since the lower end of the limiting rod 401 is stuck under the limiting sleeve 402, the limiting rod 401 cannot continue to move upward, preventing the upper pressure plate 301 from tilting too much and avoiding overturning.

[0031] In one embodiment, the two sides of the working plate 103 extend beyond the outer side of the support plate 102. Correspondingly, the limiting component 4 is installed on the part of the working plate 103 that extends beyond the support plate 102. The installation space of the limiting component 4 is unobstructed and easy to assemble.

[0032] Preferably, the limiting component 4 is located at the center of the working plate 103 beyond the support plate 102 to maintain balanced force and similar force in all directions.

[0033] Among them, the weighing sensor 2 adopts a column-type weighing sensor or a cantilever weighing sensor, that is, the weighing module of this application can adapt to different types of weighing sensors 2.

[0034] The base plate 101 has multiple first fixing holes 108 for installation in the usage position. The upper pressure plate 301 has multiple second fixing holes 305 for mounting the upper pressure plate 301 on an integral weighing housing. Multiple structures disclosed in this application can be installed on the same weighing housing at the same time.

[0035] The base plate 101 has mounting holes 109 for mounting the load cell 2, which facilitates fixing the load cell 2.

[0036] In the transportation of the I-beam weighing module of this application, a pad is placed between the upper pressure plate 301 and the working plate 103 to prevent the upper pressure plate 301 from shaking and being damaged during transportation.

[0037] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
