Detailed Description
The present invention will be further described with reference to specific embodiments and drawings, in which more details are set forth in the following description in order to provide a thorough understanding of the present invention, but it will be apparent that the present invention can be embodied in many other forms than described herein, and that those skilled in the art may make similar generalizations and deductions depending on the actual application without departing from the spirit of the present invention, and therefore should not be construed to limit the scope of the present invention in terms of the content of this specific embodiment.
It should be noted that fig. 1 to 9 are only examples, which are not drawn to scale, and should not be taken as limiting the scope of protection actually required by the present invention.
As shown in fig. 1 to 3, in a comparative example, for limiting the relative movement of the load cell 1 of the platform balance with respect to the fixed portion 2, the limiting is mainly performed by providing a limiting member such as a limiting post 3a, 3b or a limiting adjusting screw 4a, 4b on the fixed portion 2, and the common feature is that a certain distance G1, G2 is provided between the load cell 1 and the limiting post 3a, 3b or the limiting adjusting screw 4a, 4b, and when the load cell 1 receives a force perpendicular to the direction of the supporting force received by the load cell, the load cell 1 moves toward the limiting post 3a, 3b or the limiting adjusting screw 4a, 4b until contacting the limiting post 3a, 3b or the limiting adjusting screw 4a, 4b, thereby realizing the limiting. The side face of the weighing sensor is extruded due to the limiting mode, so that protection of the weighing sensor is not facilitated. In addition, when the size of the weighing sensor is changed, the distances G1 and G2 are also changed, and in order to realize the limiting function, the distances G1 and G2 need to be readjusted. For the limiting mode of the limiting posts 3a, 3b, the limiting posts 3a, 3b are welded on the fixing part 2, so that different fixing parts 2 need to be designed to meet the requirements. For the limiting mode of the limiting screws 4a and 4b, the positions of the limiting screws 4a and 4b are required to be manually adjusted to meet the limiting requirement, and the workload is additionally increased.
Aiming at the problems in the comparative examples, the technical scheme of the invention provides the following improvement:
as shown in fig. 5 and 6, the invention provides a platform balance, which comprises a movable part 9 and a fixed part 2, wherein a weighing sensor 1 and a limiting module 17 are installed on the movable part 9, and the limiting module 17 is used for limiting the relative movement between the weighing sensor 1 and the fixed part 2.
Preferably, as shown in fig. 5 and 9, the movable portion 9 is rectangular, four limit modules 17 are welded to four corner regions, and four weighing sensors 1 are mounted on the four limit modules 17. The fixed part 2 is also rectangular, and the movable part 9 covers over the fixed part 2. The fixing part 2 is connected to the load cell 1 and forms a support for the load cell 1 at the connection. The fixing part 2 comprises a frame of a platform scale, and the frame of the platform scale can be fixedly connected with the ground in a welding or bolt fixing mode. The movable part 9 comprises a weighing platform for receiving the weight of the object to be weighed.
Preferably, the weighing sensor 1 is mounted on the limit module 17, and the weighing sensor 1 is fixedly connected with the limit module 17 through a bolt 16.
Further, as shown in fig. 4, the limit module 17 includes a base plate 17a, a wall plate 17b perpendicular to the base plate 17a is disposed at an edge of the base plate 17a, and the wall plate 17b and the base plate 17a enclose a groove 18 for mounting the weighing sensor 1; the wall plate 17b includes a limiting plate 5 for contacting the fixed portion 2 to limit the relative movement between the load cell 1 and the fixed portion 2. The recess 18 is used for accommodating the load cell 1, so that the load cell 1 is easy to protect and position the cables of the load cell, and the wall plate 17b can reduce dust entering. The limit module 17 can be formed in one step by a dewaxing casting process to reduce machining effort. In addition, the wall plate 17b also helps to improve the rigidity and mechanical properties of the scale body.
Further, as shown in fig. 4, the wall plate 17b is provided with a threaded through hole 8 in a direction perpendicular to the base plate 17a, and the threaded through hole 8 is used for leveling the platform balance. The threaded through hole 8 and the limit module 17 are designed into a whole, which has the advantages that: so that the threaded through hole 8 is closer to the load cell 1, the scale angle is easily lifted during leveling, and if the threaded through hole 8 is farther from the load cell 1, it becomes difficult to lift the scale angle during leveling.
Further, as shown in fig. 7, an opening matched with the threaded through hole 8 is formed in the body panel of the platform balance for inserting the leveling rod 11. Preferably, the leveling rod 11 may be provided in an L-shape, or other structure that is easy to operate and at the same time saves effort, with the final objective of conveniently leveling through the provision of the threaded through-hole 8. One side of the L-shaped leveling rod 11 is provided with external threads matched with the threaded through hole 8, and the side length is enough to penetrate through the threaded through hole 8.
Preferably, as shown in fig. 9, the threaded through hole 8 is connected to the eye screw 14 at one end of the movable portion 9 to perform a lifting function. The threaded through hole 8 is located at one end of the fixing portion 2 and is connected with the conveying support leg 13 to achieve the conveying function.
Preferably, the recess 18 is curved in a longitudinal direction to form a first groove portion 18a and a second groove portion 18b perpendicular to each other, and the load cell 1 is mounted in one of the first groove portion 18a and the second groove portion 18 b. The groove 18 adopts a bending design, so that the length of the stressed part of the groove 18 can be increased when the weighing sensor 1 receives horizontal forces in different directions, and the phenomenon of stress concentration is avoided.
Preferably, a first guiding hole 19a for threading is formed at one end of the groove 18 located at the first groove portion 18a, a second guiding hole 19b for threading is formed at one end of the groove 18 located at the second groove portion 18b, and central lines of the first guiding hole 19a and the second guiding hole 19b are perpendicular to each other. This design prevents the cables of the load cell 1 from being exposed outside the body panel of the platform balance when they pass through the wall plate 17b, thereby protecting the cables of the load cell 1.
Preferably, the fixing part 2 comprises a connecting seat 6, and a sensor support 7 for floatingly supporting the weighing sensor 1 is arranged on the connecting seat 6. The floating support includes a tumbler type support, an elastic support, and the like. The floating support allows relative movement between the movable part 9 and the fixed part 2 in a direction perpendicular to the supporting force.
Preferably, the wall plate 17b includes at least one stopper plate 5, a gap 10 exists between at least one side of the stopper plate 5 and the fixed portion 2, and the stopper plate 5 is capable of following the load cell 1 to move in a direction of narrowing the gap 10 to be in contact with the scale fixed portion 2.
Preferably, the limiting plate 5 includes a first limiting plate 5a and a second limiting plate 5b disposed perpendicular to each other. The first limiting plate 5a and the second limiting plate 5b are perpendicular to each other and connected.
Preferably, as shown in fig. 4, the limiting plate 5 is provided with a cleaning hole 12. The cleaning holes 12 are used for periodic cleaning maintenance of the load cell.
The limiting process of the invention is described as follows: as shown in fig. 6, in the stationary state, a gap 10 exists between the second limiting plate 5b and the connection seat 6, the weighing sensor 1 is fixedly connected to the limiting module 17, and the limiting module 17 is fixedly connected to the movable portion 9. When the movable portion 9 receives a force in the horizontal leftward direction, the movable portion 9, the limit module 17 (the second limit plate 5 b), and the load cell 1 have a tendency to move leftward. When the weighing sensor 1 is in floating connection with the connecting seat 6 (the fixed part 2), the movable part 9, the limiting module 17 (the second limiting plate 5 b) and the weighing sensor 1 can have obvious leftward movement relative to the connecting seat 6 (the fixed part 2), and the gap 10 can be reduced until the limiting plate 5b is in contact with the connecting seat 6 (the fixed part 2), so that the limiting function is realized.
The leveling process of the present invention is described as follows: during leveling, the leveling rod 11 is inserted into the threaded through hole 8 on one side of the platform scale, the height of which needs to be lifted, and the leveling rod is rotated, so that the insertion end of the leveling rod 11 gradually penetrates through the threaded through hole 8 until the leveling rod contacts with the fixing surface of the platform scale, and the leveling rod 11 is continuously rotated to lift the platform scale. And after the platform scale is lifted to a proper height, a gasket is plugged into the lower part of the platform scale, so that the platform scale is kept at the proper height, and the leveling function of the platform scale is realized.
The invention has the positive progress effects that: according to the invention, the limiting plate 5 on the limiting module 17 is contacted with the fixed part 2 instead of the weighing sensor 1 by mounting the limiting module 17 on the movable part 9, so that the weighing sensor 1 is protected. In addition, in the limiting mode of the invention, the specific gap 10 is not required to be kept between the weighing sensor 1 and the fixed part 9, and instead, the specific gap 10 is kept between the limiting plate 5 on the limiting module 17 and the fixed part 9, so that when the size of the weighing sensor 1 is changed, the limiting function of the limiting module 17 is not influenced by the size change of the weighing sensor 1, and the applicability of the limiting module 17 is greatly enhanced.
In addition, the platform scale can be conveniently supported by the threaded through hole 8 arranged on the platform scale in cooperation with the leveling rod 11, so that the leveling operation is simple and feasible.
