[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: Figures 1-5 As shown, this utility model provides a quick-release weighing block installation structure, including a lower mounting base plate 1, a weighing sensor 101 is provided on the top of the lower mounting base plate 1, a load-bearing rod 102 is provided at one end of the top of the weighing sensor 101, an upper mounting top plate 103 is provided on the top of the load-bearing rod 102, a hopper bottom plate 104 is provided on the top of the upper mounting top plate 103, and circular holes are provided at the four corners of the upper mounting top plate 103 and the hopper bottom plate 104, with a press quick-release component 2 provided in the circular holes;
[0023] The quick-release assembly 2 includes a connecting ring 201 disposed within a circular hole in the upper mounting plate 103. A support ring 202 is disposed within the connecting ring 201. A push-button switch 203 is disposed at the top of the support ring 202, and a support rod 204 is disposed at the bottom of the push-button switch 203. A spring 205 is fitted onto the surface of the support rod 204, and a sliding guide rail 206 is disposed at the bottom of the support rod 204. Ball bearings 207 are disposed on both sides of the sliding guide rail 206. The quick-release assembly 2 is the core component for achieving rapid installation and disassembly. In the initial state, the spring... When 205 is in its naturally extended state, it pushes the sliding guide rail 206 and the ball bearings 207 on both sides outward. At this time, part of the ball bearings 207 protrudes from the sliding guide rail 206 and can engage with the inner wall of the connecting ring 201. During installation, first, the connecting ring 201 is placed into the circular hole of the upper mounting plate 103 and fixed. Then, the support ring 202, along with the internal push switch 203, support rod 204, spring 205, sliding guide rail 206, and ball bearings 207, is placed into the connecting ring 201 through the circular hole of the hopper bottom plate 104. Pressing the push switch 203 downwards causes the support rod 204 to move downwards, compressing the spring 205. Simultaneously, the sliding guide rail 206 moves downwards, and the balls 207 on both sides are squeezed inwards by the inner wall of the connecting ring 201, causing them to disengage from the inner wall of the connecting ring 201. The entire assembly can then slide smoothly within the circular hole. When the support ring 202, along with the internal components, reaches the appropriate position, releasing the push switch 203 causes the spring 205, now free from external force, to extend and reset, pushing the support rod 204 upwards. The movement causes the sliding guide rail 206 to move upward, and the balls 207 on both sides to protrude outward again and lock onto the inner wall of the connecting ring 201, so that the support ring 202 and the connecting ring 201 are firmly connected, thereby firmly assembling the hopper bottom plate 104 and the upper mounting plate 103 together and completing the installation process. When disassembling, press the press switch 203 again to repeat the process of spring 205 compression and ball 207 retraction, so that the locking between the components is released, and the hopper bottom plate 104 and the upper mounting plate 103 can be easily separated to achieve quick disassembly.
[0024] like Figure 4As shown, one end of the spring 205 is connected to the bottom of the push switch 203, and the other end is fixed to the top of the sliding guide rail 206. This connection method provides a stable force support point for the spring 205. When the switch 203 is pressed, the spring 205 is compressed along the fixed axis. After the switch is released, the spring 205 can only extend and return to its original position along this axis, which avoids the spring 205 from twisting or shifting during the force process. This ensures that the ball 207 can accurately extend and retract according to the design path, so that the quick-release assembly 2 can accurately achieve engagement and disengagement in each operation, ensuring the reliability and reusability of the installation structure.
[0025] like Figure 5 As shown, the bottom of the support ring 202 has a slot that matches the size of the ball bearing 207. During installation, when the switch 203 is pressed to retract the ball bearing 207, the ball bearing 207 can smoothly slide into the slot, preventing it from rolling or misaligning within the support ring 202. When the switch 203 is released, the spring 205 returns to its original position, pushing the sliding guide rail 206 upward. The slot guides the ball bearing 207 to extend accurately and engage with the inner wall of the connecting ring 201, ensuring precise engagement and improving the fixing effect and installation efficiency. The threaded protrusions on the surface of the connecting ring 201 match the threaded grooves in the circular holes of the upper mounting plate 103. By screwing the threads together, the connecting ring 201 is firmly fixed to the upper mounting plate 103. Compared with simple embedding, the threaded connection provides greater friction and fastening force, which can effectively prevent the connecting ring 201 from loosening or falling off due to force during the weighing process. This ensures the connection stability between the entire press-and-release assembly 2 and the upper mounting plate 103, providing a reliable foundation for the subsequent installation of components such as the hopper bottom plate 104.
[0026] like Figure 5 As shown, the contact surface between the inner wall of the connecting ring 201 and the ball 207 is designed with an arc shape. When the ball 207 is pushed outward by the spring 205, the arc surface can form a good fit with the ball 207, so that the ball 207 is evenly stressed when it is engaged, avoiding local stress concentration that could lead to wear or loose engagement. At the same time, when the switch 203 is pressed to retract the ball 207, the arc surface can guide the ball 207 to move inward more smoothly, reducing frictional resistance and making the pressing operation easier and less strenuous.
[0027] like Figure 1 As shown, the elastic buffer pad installed between the upper mounting plate 103 and the hopper bottom plate 104 can absorb and buffer this pressure when the hopper is carrying material during the weighing process. This pressure is transmitted to the upper mounting plate 103. The elastic buffer pad can absorb and buffer this pressure, preventing the pressure from directly impacting the weighing sensor 101. This reduces the impact of vibration caused by material loading and unloading on the accuracy of the weighing data, ensuring that the weighing sensor 101 works stably and accurately.
[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
