[0029] See also Figure 1-5A waterproof electronic platform scale, comprising an electronic platform scale body 1, the electronic platform scale body comprising a scale plate 2 and a base 3, a driving chamber 4 is arranged in the scale plate 2, a rotating rod 5 is rotatably arranged in the driving chamber 4, one end of the rotating rod 5 passes through the driving chamber 4 and is fixedly connected with a rotating handle 6, two driving bevel gears 7 are fixedly arranged on the rotating rod 5, the driving bevel gear 7 is meshingly connected with a driven bevel gear 8, a first screw rod 9 is fixedly arranged on the upper end of the driven bevel gear 8, the upper end of the first screw rod 9 passes through the driving chamber 4 and is threadedly connected with a sleeve 10, a limiting rod 11 is fixedly arranged on the upper end of the sleeve 10, two receiving grooves 12 that are matched with the limiting rod 11 and the sleeve 10 are arranged on the scale plate 2, two positioning plates 13 are fixedly arranged at the lower end of the limiting rod 11, and two positioning grooves 14 that are matched with the positioning plates 13 are arranged on both sides of the scale plate 2;

[0030] A support plate 15 is hingedly connected to the lower end of the base 3 , and a support seat 16 is fixedly disposed at the lower end of the support plate 15 .

[0031] In this embodiment, when it is necessary to weigh items with circular or arc-shaped parts, the handle 6 is turned, the handle 6 drives the rotating rod 5 to rotate, the rotating rod 5 drives the driving bevel gear 7 to rotate, the driving bevel gear 7 drives the driven bevel gear 8 to rotate, the driven bevel gear 8 drives the first screw 9 to rotate, and since the first screw 9 is threadedly connected with the sleeve 10, the sleeve 10 moves upward, the sleeve 10 drives the limiting rod 11 to move upward, the limiting rod 11 drives the two positioning plates 13 to move in the positioning groove 14, so that the two limiting rods 11 extend from the storage groove 12 to block and limit the items with circular or arc-shaped parts placed above the scale plate 2, thereby preventing the items from rolling down during the weighing process. The working principle of the electronic platform scale body 1 is the prior art, and its working principle is not repeated here.

[0032] More specifically, the handle 6 can be rotated to allow the two limiting rods 11 to extend from the storage slot 12, thereby limiting the position of the object to be weighed. When the entire platform scale needs to be placed on an inclined support surface for use, the base 3 is pushed to rotate around the hinged connection of the support plate 15, thereby adjusting the horizontal position of the base 3 to keep it horizontal.

[0033] See also Figure 1-5As an implementation method for adjusting the base 3: a moving chamber 17 is provided at the upper end of the support seat 16, a lead screw 18 is rotatably provided in the moving chamber 17, one end of the lead screw 18 passes through the support seat 16 and is fixedly connected to a handle 19, a moving seat 20 is threadedly connected to the lead screw 18, both sides of the moving seat 20 are slidably connected to the moving chamber 17 through a track structure, a pushing plate 21 is hingedly connected between the moving seat 20 and the base 3, four second screws 22 are fixedly provided at the lower end of the support seat 16, each of the second screws 22 is threadedly connected to an adjusting cylinder 23 on the outer side, and an adjusting seat 24 is fixedly provided at the lower end of the adjusting cylinder 23.

[0034] Specifically, the four adjusting cylinders 23 are rotated in sequence. Since the adjusting cylinder 23 is threadedly connected to the second screw 22, the adjusting cylinder 23 rotates and drives the adjusting seat 24 to move, so that the support seat 16 is stably placed on the support surface. The handle 19 is turned, and the handle 19 drives the lead screw 18 to rotate. Since the lead screw 18 is threadedly connected to the moving seat 20, the moving seat 20 moves along the moving chamber 17. The moving seat 20 drives the push plate 21 to rotate, so that the push plate 21 pushes the base 3 to rotate around the hinged connection with the support plate 15. A level 27 is installed on one side of the base 3, and the base 3 can be adjusted to a level by observing the level 27.

[0035] See also Figure 1-5 As an implementation method for waterproofing between the scale plate 2 and the base 3: a waterproof ring 25 is fixedly provided on the outer side of the scale plate 2, and a water retaining ring 26 is fixedly provided on the inner side of the waterproof ring 25.

[0036] Specifically, the waterproof ring 25 can block the gap between the scale plate 2 and the base 3 to prevent water from entering between the scale plate 2 and the base 3. When water accidentally splashes from the lower end of the waterproof ring 25 to between the waterproof ring 25 and the base 3, the water retaining ring 26 blocks the splashing water. At the same time, the water retaining ring 26 is tilted so that the splashing water flows out of the waterproof ring 25 along the water retaining ring 26.

[0037] In summary, when the overall equipment is in use:

[0038] When the entire electronic platform scale needs to be placed on an inclined support surface, the four adjusting cylinders 23 are rotated in sequence. Since the adjusting cylinder 23 is threadedly connected to the second screw 22, the adjusting cylinder 23 rotates and drives the adjusting seat 24 to move, so that the support seat 16 is stably placed on the support surface. The handle 19 is turned, and the handle 19 drives the lead screw 18 to rotate. Since the lead screw 18 is threadedly connected to the moving seat 20, the moving seat 20 moves along the moving chamber 17. The moving seat 20 drives the push plate 21 to rotate, so that the push plate 21 pushes the base 3 to rotate around the hinged connection with the support plate 15. A level 27 is installed on one side of the base 3, and the base 3 can be adjusted to a level by observing the level 27.

[0039] When it is necessary to weigh items with circular or arc-shaped parts, turn the handle 6, the handle 6 drives the rotating rod 5 to rotate, the rotating rod 5 drives the driving bevel gear 7 to rotate, the driving bevel gear 7 drives the driven bevel gear 8 to rotate, the driven bevel gear 8 drives the first screw 9 to rotate, and the first screw 9 is threadedly connected to the sleeve 10, so that the sleeve 10 moves upward, the sleeve 10 drives the limiting rod 11 to move upward, the limiting rod 11 drives the two positioning plates 13 to move in the positioning groove 14, so that the two limiting rods 11 extend from the storage groove 12 to block and limit the items with circular or arc-shaped parts placed above the scale plate 2, thereby preventing the items from rolling down during the weighing process. The working principle of the electronic platform scale body 1 is the existing technology, and its working principle is not repeated here.

[0040] When waterproofing is required, the waterproof ring 25 can block the gap between the scale plate 2 and the base 3 to prevent water from entering between the scale plate 2 and the base 3. When water accidentally splashes from the lower end of the waterproof ring 25 to between the waterproof ring 25 and the base 3, the water retaining ring 26 blocks the splashing water. At the same time, the water retaining ring 26 is tilted so that the splashing water flows out of the waterproof ring 25 along the water retaining ring 26.

[0041] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
