Description

Technical Field

[0001] The utility model relates to the field of electronic scales, in particular to a platform scale and a novel bracket thereof. Background Art

[0002] A platform scale is a commonly used weighing device. The platform scale should have a sensor installation structure for installing a weighing sensor. The weighing sensor is actually a device that converts a mass signal into a measurable electrical signal for output. Its working principle is as follows: One end of the sensor is fixed to the lower weighing platform, and the other end is connected to the upper weighing platform and the weighing pan. When the weighing pan is loaded with weight, the sensor generates a downward deformation, and the strain gauge attached to it converts this deformation and displacement into an electrical signal.

[0003] The platform scale bracket of an electronic platform scale includes a sensor, an upper frame, and a lower frame. The sensor is arranged between the upper frame and the lower frame, and the weighing weight on the upper frame is transmitted to the sensor. The existing platform scale brackets can be referred to in the attached Figure 1 and 2 As shown, two main beam tubes are arranged on both sides of the central axis in the length direction of both the upper frame 2 and the lower frame 3. Sensor fixing blocks 4 are respectively welded between the two main beam tubes of the upper frame 2 and the lower frame 3. The upper and lower end faces of both ends of the sensor 1 are respectively fixedly connected to the two sensor fixing blocks 4.

[0004] However, the disadvantage of the above solution is that: Since the sensor fixing block of the sensor is welded and fixed between the two main beam tubes, specifically, the sensor fixing block is welded to the side walls of the two main beam tubes through its two side edges. Thus, it is necessary to position the sensor fixing block through a welding jig to ensure that the welding heights on both sides of the sensor fixing block are the same, and further ensure that the sensor fixing block is parallel to the upper and lower frames. But such an operation will make the welding positioning slower and the processing efficiency lower. Summary of the Invention

[0005] In order to solve the above problems, the first object of the utility model is to provide a novel bracket for a platform scale. This solution can simplify the welding positioning requirements, make the welding jig simpler, and the welding positioning faster, so as to improve the production efficiency.

[0006] In order to achieve the above object, the utility model adopts the following technical solutions:

[0007] A novel bracket, comprising a sensor, an upper frame and a lower frame; both ends of the sensor are fixedly connected to the upper frame and the lower frame respectively through sensor fixing blocks; it is characterized in that: the upper frame comprises an upper frame body and an upper main beam tube connected to the upper frame body and passing through the center thereof; the lower frame comprises a lower frame body and a lower main beam tube connected to the lower frame body and passing through the center thereof; the upper main beam tube and the lower main beam tube are arranged parallel to each other up and down, and sensor fixing blocks are fixedly attached flatly to the lower end surface of the upper main beam tube and the upper end surface of the lower main beam tube, the length direction of the sensor is arranged along the length directions of the upper main beam tube and the lower main beam tube, and the upper and lower end surfaces of both ends of the sensor are fixedly connected to the two sensor fixing blocks respectively.

[0008] The present utility model adopts the above technical solution, which relates to a novel bracket on a platform scale. The sensor of the novel bracket is arranged between the upper frame and the lower frame, and the weighing weight on the upper frame is transmitted to the sensor, so as to achieve the weighing purpose. On this basis, the difference between this solution and the prior art is that: the upper main beam tube in the upper frame of this solution passes through the center of the upper frame body, and the lower main beam tube in the lower frame passes through the center of the lower frame body; then the sensor fixing blocks are fixedly attached flatly to the lower end surface of the upper main beam tube and the upper end surface of the lower main beam tube, and then the upper and lower end surfaces of both ends of the sensor are fixedly connected to the two sensor fixing blocks respectively.

[0009] Compared with the solution described in the background art, in this solution, both the upper main beam tube and the lower main beam tube pass through the centers of the upper frame body and the lower frame body. In this way, the sensor fixing blocks do not need to be arranged between the two main beam tubes, but can be directly fixedly attached flatly to the lower end surface of the upper main beam tube and the upper end surface of the lower main beam tube. Such a solution can simplify the welding positioning requirements, make the welding fixture simpler, and the welding positioning faster, so as to improve the production efficiency.

[0010] In a further embodiment, the two sensor fixing blocks are respectively welded flatly to the lower end surface of the upper main beam tube and the upper end surface of the lower main beam tube. In this solution, the two sensor fixing blocks are welded to the upper main beam tube and the lower main beam tube to increase the thickness and strength at the connection with the sensor. The welding requires the sensor fixing blocks to be welded flatly, so as to ensure that the sensor fixing blocks are parallel to the upper frame and the lower frame.

[0011] Furthermore, through holes for screw fixing components to pass through are provided on the upper main beam tube, the lower main beam tube, the sensor fixing blocks fixed thereto, and both ends of the sensor; both ends of the sensor are respectively connected to the two sensor fixing blocks through screw fixing components. During installation, after welding the two sensor fixing blocks to the upper main beam tube and the lower main beam tube, through holes communicating with both ends of the sensor are required to be provided on the upper main beam tube, the lower main beam tube and the sensor fixing blocks fixed thereto. After aligning the two ends of the sensor with the positions of the upper frame and the lower frame, they can be fixedly connected through screw fixing components.

[0012] Preferably, both the upper frame and the lower frame are constructed to have a length greater than the width to ensure the stability of the platform scale and prevent it from tipping over easily. Further, the upper main beam tube is arranged along the central axis of the length direction of the upper frame, and the lower main beam tube is arranged along the central axis of the length direction of the lower frame.

[0013] As Figure 1 and 2 shown in the background technical solution, a trapezoidal block is also welded at the front end of the lower frame, and a folding device fixing tube is welded above the trapezoidal block. This solution makes the structure of the lower frame more complex and the welding process numerous. In this solution, the front end of the lower main beam tube extends out of the front edge of the upper frame and is integrally bent upward to form the folding device fixing tube. In this way, the lower main beam tube and the folding device fixing tube are composed of the same pipe fitting. The lower main beam tube extends forward and bends upward to replace the traditional folding device fixing tube, which can simplify the structure of the lower frame, simplify the process, and improve production efficiency.

[0014] Further, the lower frame body includes two support feet for supporting the lower main beam tube. The front end of the lower main beam tube extends out of the front support feet and is integrally bent upward. A bayonet is constructed on the upper end of the two support feet and / or the lower end surface of the lower main beam tube. The lower main beam tube is snapped into the bayonets of the two support feet and / or the two support feet are snapped into the bayonets of the lower main beam tube, so as to realize the quick docking and positioning of the lower main beam tube and the two support feet. Further, welding can be used for reinforcement.

[0015] Preferably, the upper frame is constructed in a "day" shape.

[0016] The second object of the present invention is to provide a platform scale, which is characterized in that it includes the novel bracket as described above. BRIEF DESCRIPTION OF THE DRAWINGS

Embodiment 1

[0027] As shown in Figures 3 to 5 the figure, this embodiment relates to a new type of bracket, including a sensor 1, an upper frame 2 and a lower frame 3; both ends of the sensor 1 are fixedly connected to the upper frame 2 and the lower frame 3 through sensor 1 fixing blocks respectively. The upper frame 2 includes an upper frame body 21 and an upper main beam tube 22 connected to the upper frame body 21 and passing through its center. The lower frame 3 includes a lower frame body and a lower main beam tube 32 connected to the lower frame body and passing through its center. The upper main beam tube 22 and the lower main beam tube 32 are arranged parallel to each other up and down. Sensor fixing blocks 4 are fixedly attached flat on the lower end face of the upper main beam tube 22 and the upper end face of the lower main beam tube 32. The length direction of the sensor 1 is arranged along the length directions of the upper main beam tube 22 and the lower main beam tube 32, and the upper and lower end faces at both ends of the sensor 1 are fixedly connected to the two sensor fixing blocks 4 respectively.

[0028] The sensor 1 of this new type of bracket is arranged between the upper frame 2 and the lower frame 3. The weighing weight on the upper frame 2 is transmitted to the sensor 1, so as to achieve the purpose of weighing. On this basis, the difference between this solution and the prior art is that: in this solution, the upper main beam tube 22 in the upper frame 2 passes through the center of the upper frame body 21, and the lower main beam tube 32 in the lower frame 3 passes through the center of the lower frame body. Then, the sensor fixing blocks 4 are fixedly attached flat on the lower end face of the upper main beam tube 22 and the upper end face of the lower main beam tube 32, and then the upper and lower end faces at both ends of the sensor 1 are fixedly connected to the two sensor fixing blocks 4 respectively.

[0029] Compared with the solution described in the background art, in this solution, both the upper main beam tube 22 and the lower main beam tube 32 pass through the centers of the upper frame body 21 and the lower frame body. In this way, the sensor fixing blocks 4 do not need to be arranged between the two main beam tubes, but can be directly fixedly attached flat on the lower end face of the upper main beam tube 22 and the upper end face of the lower main beam tube 32. Such a solution can simplify the welding positioning requirements, make the welding fixture simpler, and the welding positioning faster, so as to improve the production efficiency.

[0030] In a further embodiment, the two sensor fixing blocks 4 are respectively fixedly welded flat on the lower end face of the upper main beam tube 22 and the upper end face of the lower main beam tube 32. In this solution, the two sensor fixing blocks 4 are welded on the upper main beam tube 22 and the lower main beam tube 32 to increase the thickness and strength at the connection with the sensor 1. The welding requires the sensor fixing blocks 4 to be welded flat, thereby ensuring that the sensor fixing blocks 4 are parallel to the upper frame 2 and the lower frame 3.

[0031] Furthermore, through holes 10 for screw fastening members to pass through are provided on the upper main beam pipe 22, the lower main beam pipe 32, the sensor fixing blocks 4 fixedly connected thereto, and both ends of the sensor 1. Both ends of the sensor 1 are respectively connected to two sensor fixing blocks 4 through screw fastening members. During installation, after welding the two sensor fixing blocks 4 onto the upper main beam pipe 22 and the lower main beam pipe 32, it is required that through holes 10 communicating with both ends of the sensor 1 are provided on the upper main beam pipe 22, the lower main beam pipe 32, and the sensor fixing blocks 4 fixedly connected thereto. After aligning both ends of the sensor 1 with the positions of the upper frame 2 and the lower frame 3, they can be fixedly connected through screw fastening members.

[0032] As Figure 3 and 4 shown, both the upper frame 2 and the lower frame 3 are constructed to have a length greater than the width to ensure the stability of the platform scale and prevent it from tipping over easily. Further, the upper main beam pipe 22 is arranged along the central axis of the length direction of the upper frame 2, and the lower main beam pipe 32 is arranged along the central axis of the length direction of the lower frame 3. The upper frame 2 is constructed in a "day" shape.

[0033] As Figure 1 and 2 shown in the background technical solution, a trapezoidal block is also welded at the front end of the lower frame 3, and a folding device fixing pipe 5 is welded above the trapezoidal block. This solution will make the structure of the lower frame 3 more complex and the welding process more numerous. In this solution, the front end of the lower main beam pipe 32 extends out of the front side edge of the upper frame 2 and is integrally bent upward to form the folding device fixing pipe 5. In this way, the lower main beam pipe 32 and the folding device fixing pipe 5 are formed by the same pipe fitting. The lower main beam pipe 32 extends forward and bends upward to replace the traditional folding device fixing pipe 5, which can simplify the structure of the lower frame 3, simplify the process, and improve production efficiency. Further, the lower frame body includes two support feet 33 for supporting the lower main beam pipe 32. The front end of the lower main beam pipe 32 extends out of the front support feet 33 and is integrally bent upward. Buckles 321 are constructed on the upper ends of the two support feet 33 and / or the lower end surface of the lower main beam pipe 32. The lower main beam pipe 32 is snapped into the buckles 321 of the two support feet 33 and / or the two support feet 33 are snapped into the buckles 321 of the lower main beam pipe 32, so as to realize the quick docking and positioning of the lower main beam pipe 32 and the two support feet 33, and further, a welding method can be used for reinforcement.
