Technical Field

[0001] This utility model relates to the field of weighing instrument technology, specifically to a dynamic and static weighing instrument. Background Technology

[0002] Dynamic and static weighing instruments are an indispensable piece of equipment in the field of industrial measurement. They can measure the weight of objects with high precision, whether in static or dynamic environments. They use high-precision sensors and advanced microprocessor technology to ensure accurate measurement results in various environments. They can also convert the weighing sensor signal into a digital weight display for easy and intuitive observation of weight data.

[0003] Currently, dynamic and static weighing instruments use external protective covers to protect the display screen. However, the disassembly and assembly of the protective cover and the weighing instrument is inconvenient, and the protective cover cannot be quickly removed or assembled. Furthermore, gaps exist between the protective cover and the weighing instrument, allowing moisture to easily seep into the instrument and damage its internal components. In addition, the position and angle of the weighing instrument cannot be adjusted adaptively when installed in different areas, making it difficult to install the weighing instrument at a suitable angle for use and hindering the observation of weighing data.

[0004] Therefore, we propose a dynamic and static weighing instrument to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a dynamic and static weighing instrument to solve the problems mentioned in the background art, such as the inconvenience of disassembling and assembling the protective cover and the dynamic and static weighing instrument, the gap between the protective cover and the weighing instrument, the low sealing performance, and the inability to adapt the position and angle of the weighing instrument when it is installed in different areas.

A rotating shaft is installed at one end of the slider that extends out of the mounting seat. A limit block is connected to the side of the rotating shaft. A mounting bracket is sleeved on the outside of the rotating shaft and the limit block.

[0010] Preferably, the sealing strip is distributed between the fixed frame and the protective cover, and the front part of the sealing strip and the protective cover is distributed in an inclined manner on the contact side.

[0011] Preferably, the positioning rod slides through the end of the mounting column, and the positioning rod engages with the positioning plate.

[0012] Preferably, the front end of the positioning plate is open, and the height of the opening of the positioning plate is greater than the outer diameter of the connecting rod.

[0013] Preferably, the rotating shaft forms a sliding structure with the mounting frame via a limiting block, and the mounting frame forms a rotating structure with the slider via the rotating shaft, with the slider sliding through the mounting base.

[0014] Preferably, the connecting rod is connected between two positioning rods distributed vertically, and the connecting rods are symmetrically distributed about the longitudinal center line of the protective cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The dynamic and static weighing instrument can increase the sealing between the protective cover and the fixed frame by using the sealing strip, so as to protect the weighing instrument body from dust and moisture. Furthermore, by driving the connecting rod to move, the positioning rod can be controlled to move. With the use of the spring, the relative position between the positioning rod and the positioning plate can be flexibly adjusted, so as to realize the flexible disassembly and assembly of the protective cover. The operation is simple and convenient.

[0025] 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.

[0026] Please see Figures 1-6 The present invention provides the following technical solution: a dynamic and static weighing instrument, including a weighing instrument body 1, a fixed frame 2 installed on the front side of the weighing instrument body 1, a sealing strip 3 connected to the outer side of the fixed frame 2, and a protective cover 4 attached to the outer side of the sealing strip 3.

[0027] Furthermore, the sealing strip 3 is distributed between the fixed frame 2 and the protective cover 4. The front part of the contact side of the sealing strip 3 and the protective cover 4 is distributed in an inclined manner, so that the protective cover 4 and the sealing strip 3 are tightly fitted, thereby improving the sealing performance between the fixed frame 2 and the protective cover 4.

[0028] A mounting post 5 is installed on the side of the protective cover 4. A spring 6 is connected inside the mounting post 5. A positioning rod 7 is connected to the end of the spring 6. A connecting rod 14 is installed at the end of the positioning rod 7. A positioning plate 8 is installed on the front side of the weighing instrument body 1.

[0029] Furthermore, the positioning rod 7 slides through the end of the mounting column 5, and the positioning rod 7 and the positioning plate 8 engage with each other, allowing the positioning rod 7 to move smoothly. By adjusting the relative position between the positioning rod 7 and the positioning plate 8, the protective cover 4 can be disassembled and assembled.

[0030] Furthermore, the front end of the positioning plate 8 is open, and the height of the opening of the positioning plate 8 is greater than the outer diameter of the connecting rod 14, which allows the connecting rod 14 to move smoothly at the opening of the positioning plate 8, driving the positioning rod 7 to move.

[0031] Furthermore, the connecting rod 14 is connected between the two positioning rods 7 distributed vertically. The connecting rod 14 is symmetrically distributed about the longitudinal center line of the protective cover 4. The connecting rod 14 can be used to realize the synchronous movement of the two positioning rods 7 distributed vertically, and the position of the positioning rods 7 can be adjusted.

[0032] The weighing instrument body 1 is equipped with mounting bases 9 on both the left and right sides. A slider 10 is provided inside the mounting base 9. A rotating shaft 11 is installed at one end of the slider 10 that extends out of the mounting base 9. A limit block 12 is connected to the side of the rotating shaft 11. A mounting bracket 13 is sleeved on the outside of the rotating shaft 11 and the limit block 12.

[0033] Furthermore, the rotating shaft 11 forms a sliding structure with the mounting bracket 13 through the limiting block 12, and the mounting bracket 13 forms a rotating structure with the slider 10 through the rotating shaft 11. The slider 10 slides through the mounting base 9, and the position of the rotation point of the mounting bracket 13 can be adjusted to adapt to the spatial distribution of the installation area for the installation of the weighing instrument body 1.

[0034] Specifically, press the connecting rod 14 towards the protective cover 4, causing the connecting rod 14 to move the positioning rod 7 installed at the end. The positioning rod 7 compresses and stores the spring 6, moving the positioning rod 7 out of the positioning plate 8, thus releasing the limit on the protective cover 4. The protective cover 4 can then be removed for maintenance of internal components, display screens, etc. Continue pressing the connecting rod 14 to snap the protective cover 4 onto the outside of the fixing frame 2 and compress the sealing strip 3, causing the sealing strip 3 to deform under pressure, increasing the sealing between the protective cover 4 and the weighing instrument body 1. After the protective cover 4 is installed, the pressure on the connecting rod 14 can be released, and the spring 6 controls the positioning rod 7 to reset and move, thereby snapping the positioning rod 7 into the positioning plate 8, achieving the assembly and fixation of the protective cover 4.

[0035] When installing the weighing instrument body 1, the installation angle of the weighing instrument body 1 can be adjusted according to the spatial distribution of the installation area. The rotating shaft 11 can be driven to slide within the mounting frame 13. At this time, the limiting block 12 installed on the side of the rotating shaft 11 slides on the inner wall of the mounting frame 13, and the rotating shaft 11 drives the slider 10 to slide within the mounting base 9. Adjusting the height position of the rotating shaft 11 can adjust the rotation point of the mounting frame 13, thereby adjusting the support angle range of the weighing instrument body 1. After adjustment, the slider 10 can be fixed to the mounting base 9 with bolts. Then, the mounting frame 13 is driven to rotate so that its mounting surface is parallel to the installation area. Long bolts are used to fix the rotating shaft 11, the mounting frame 13, and the slider 10. At this time, the angle position of the mounting frame 13 can be stabilized. The mounting frame 13 is then installed in the installation area, thus realizing the assembly of the weighing instrument body 1. The weighing data is displayed using the weighing instrument body 1. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
