Description

Technical Field

[0001] The utility model relates to the technical field of weighing equipment, in particular to a cover opening and closing structure of a weighing equipment. Background Art

[0002] At present, the cover structure of weighing equipment on the market is generally fixed. Its structure is mostly connected and fastened by bolts and nuts. The cover structure and the whole machine are a fully fixed installation method. The existing weighing equipment on the market has a fixed cover structure that requires frequent installation and maintenance, and is difficult to disassemble and assemble during installation, maintenance and repair. It is very time-consuming and labor-intensive, which greatly affects the installation and disassembly maintenance time of the whole machine. For this reason, we propose a movable opening and closing weighing equipment cover. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides a cover opening and closing structure for a weighing equipment. The principle is to use gravity to clamp the movable groove of the cover opening and closing structure into the riveted pins on both sides, thereby solving the pain points of the difficult installation and testing of the original fixed cover and the time-consuming after-sales maintenance.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a weighing equipment cover opening and closing structure, comprising a weighing base, the front end of which is movably connected to a weighing cover;

[0005] Two circular holes are provided on both sides of the front end of the weighing base, and a lower pin shaft and an upper pin shaft are inserted into each circular hole respectively;

[0006] An upper oblong hole and a lower oblong hole are reserved at both ends of the weighing cover plate, the ends of the lower pin shaft and the upper pin shaft extend into the lower oblong hole and the upper oblong hole respectively, and an opening is reserved on the side of the upper oblong hole.

[0007] Furthermore, the weighing cover plate can move vertically at the front end of the weighing base, and the weighing cover plate can also be flipped forward and backward after the vertical movement.

[0008] Furthermore, when the weighing cover plate is flipped forward, the upper pin shaft can transition from the inside to the outside of the upper oblong hole through the opening.

[0009] Furthermore, the upper oblong hole and the lower oblong hole are both provided with a reserve that allows the upper pin shaft and the lower pin shaft to move vertically therein.

[0010] Furthermore, a plurality of groups of weighing sensors are fixedly installed inside the weighing base, and a weighing box is fixedly installed on the top of each group of weighing sensors.

[0011] Furthermore, an upper clamping edge is arranged on the upper part of the back side of the weighing cover plate, and a lower clamping edge is arranged on the lower part of the back side.

[0012] Furthermore, a protective cover is fixedly engaged at the front end of the weighing cover plate, and the protective cover is a component made of transparent PC material.

[0013] The utility model provides a cover opening and closing structure for weighing equipment. Compared with the prior art, it has the following beneficial effects:

[0014] The cover opening and closing structure of the weighing equipment is designed as a movable opening and closing cover structure, which can make the weighing equipment more convenient during installation, testing, maintenance and repair, greatly saving working time. The movable cover opening and closing structure, due to its special structural design, can be independently installed and maintained without affecting the entire equipment, greatly improving the fault tolerance of equipment installation and maintenance.

Detailed implementation mode

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1 、 2 ., the present invention provides a technical solution: a weighing device cover opening and closing structure, including a weighing base 1, the front end of the weighing base 1 is movably connected with a weighing cover plate 2, the weighing cover plate 2 can move vertically at the front end of the weighing base 1, and the weighing cover plate 2 can also be turned forward and backward after moving vertically. A plurality of groups of weighing sensors 3 are fixedly installed inside the weighing base 1, and a weighing box 4 is fixedly installed on the upper part of each group of weighing sensors 3. A protective cover 5 is clamped and fixed at the front end of the weighing cover plate 2, and the protective cover 5 is a component made of PC transparent material.

[0028] Please refer to Figure 1 、 3 、5, two round holes 11 are respectively opened on both sides of the front end of the weighing base 1, a lower pin shaft 12 and an upper pin shaft 13 are respectively inserted into each round hole 11, upper oblong holes 21 and lower oblong holes 22 are reserved at both ends of the weighing cover plate 2, and the ends of the lower pin shaft 12 and the upper pin shaft 13 respectively extend into the lower oblong hole 22 and the upper oblong hole 21. The upper oblong hole 21 and the lower oblong hole 22 are both reserved with a margin that can correspondingly allow the upper pin shaft 13 and the lower pin shaft 12 to move vertically inside them. Only after there is such a margin can the weighing cover plate 2 move vertically. An opening 23 is reserved on the side of the upper oblong hole 21. When the weighing cover plate 2 is turned forward, the upper pin shaft 13 can transition from the inside of the upper oblong hole 21 to the outside through the opening 23.

[0029] Please refer to Figure 4 ., in order to facilitate clamping and fixing the protective cover 5 at the front end of the weighing cover plate 2, an upper clamping edge 24 is arranged on the upper part of the back of the weighing cover plate 2, and a lower clamping edge 25 is arranged on the lower part of the back. The protective cover 5 is a "U" - shaped structure with hooks at both ends. When installing the protective cover 5, as shown in the appendix Fig.10As shown, first let the hook at the lower end of the protective cover 5 engage with the lower clamping edge 25, and then flip the protective cover 5 upward and press it. Since the protective cover 5 is made of PC material and has the ability to deform, when the protective cover 5 is flipped upward and pressed, the hook at the upper end will engage with the upper clamping edge 24. In this way, the protective cover 5 is clamped and fixed to the front end of the weighing cover 2. The same applies to removing the protective cover 5.

[0030] When you need to open the weighing cover,

[0031] Step A: Hold the weighing cover 2 firmly with both hands and lift it upwards. The weighing cover 2 and the lower pin 12 and the upper pin 13 are relatively displaced. The lower pin 12 and the upper pin 13 move inside the lower oblong hole 22 and the upper oblong hole 21 respectively until the opening 23 is aligned with the position of the upper pin 13 (see attached). Figure 6 shown);

[0032] Step B: Gently rotate the weighing cover 2 outward (the front end of the weighing base 1), with the lower pin 12 as the rotation center, and then let the weighing cover 2 fall naturally. At this time, the weighing cover 2 is in the open state (as shown in the attached Figure 7 as shown).

[0033] When you need to close the weighing cover,

[0034] Step C: Flip the weighing cover plate 2 upward (with the lower pin 12 as the rotation center) so that the opening 23 is aligned with the position of the upper pin 13 (see the attached diagram). Figure 8 shown);

[0035] Step D: Gently put down the weighing cover 2. Under the action of gravity, the weighing cover 2 is in a closed state (see the attached Fig. 9 as shown).
