[0074] The waterproof balance scale 1000 according to the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0075] Reference Figures 1 to 5 As shown, the waterproof balance scale 1000 provided according to the embodiment of the utility model includes a weighing plate 10, a weighing seat 20, a weighing meter 30 and a weighing sensor connected to the weighing meter 30 by signal;

[0076] The weighing meter 30 and the weighing sensor (not shown) are both fixedly mounted in the weighing seat 20; the upper end surface of the weighing seat 20 is provided with a first opening 201 penetrating into the interior thereof and facing the weighing meter 30, and a second opening 202 facing the weighing sensor (not shown);

[0077] In addition, a waterproof panel 40 is fixedly provided at the first opening 201 and is in close contact with the weighing instrument 30; at least one circle of waterproof guardrail 203 is protruded upwardly from the upper end surface of the weighing seat 20 around the second opening 202; the weighing plate 10 is arranged above the weighing seat 20, and there is a small gap between its lower bottom surface and the upper edge of the waterproof guardrail 203, and a supporting seat 101 is provided downwardly in the middle of its bottom, which passes through the second opening 202 and is supported by the weighing sensor (not shown).

[0078] Based on the above, it can be clearly seen that when the present application is implemented specifically, it is mainly used as a waterproof balance scale 1000.

[0079] Specifically, when the present application is applied, just like a conventional ordinary balance scale, the object to be weighed is placed on the weighing plate 10 and then accurately weighed.

[0080] The present application of the above-mentioned structure, when used, will obviously have the following technical effects:

[0081] First, since the first opening 201 is fixedly provided with a waterproof panel 40 closely attached to the weighing meter 30, water stains can be better prevented from entering the weighing seat 20 through the first opening 201, so that the weighing meter 30 fixed in the weighing seat 20 and located below the first opening 201 is not easily immersed in water and burned.

[0082] Second, since at least one waterproof guard 203 is protruding upwardly around the second opening 202 on the upper end surface of the weighing seat 20, the waterproof guard 203 is provided to intercept external water stains and the like from entering the weighing seat 20 through the second opening 202, so that the weighing sensor (not shown) fixed in the weighing seat 20 and located below the second opening 202 is not easily immersed in water and burned.

[0083] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is made to have strong practicality, good safety and reliability in use, so as to achieve good use effect.

[0084] Furthermore, in the specific implementation, Figure 2 , Figure 4 and Figure 5As shown, a weighing support seat 204 is detachably fixed inside the weighing seat 20; the weighing sensor (not shown) is mounted in the weighing support seat 204; and the bottom of the supporting seat 101 is connected to the weighing support seat 204 to form a whole.

[0085] In this regard, it is clear that when items are placed on the weighing plate 10 for precise weighing, the downward pressure generated by gravity will not directly act on the weighing sensor (not shown), but will be relieved and transitioned through the weighing support seat 204, so that the weighing sensor (not shown) is not easily crushed all at once, thereby extending its service life.

[0086] Furthermore, in the specific implementation, Figure 2 and Figure 4 As shown, according to an embodiment of the present invention, the upper end surface of the weighing plate 10 is downwardly provided with a lock hole 102 penetrating to the bottom of the supporting seat 101, and the upper end surface of the weighing support seat 204 is downwardly provided with a fastening hole 2041 facing the lock hole 102;

[0087] Among them, the supporting seat 101 is connected to the weighing support seat 204 to form a whole through a locking bolt 50 that passes through the locking hole 102 and the fastening hole 2041 from top to bottom; the upper end surface of the weighing plate 10 is provided with a cover plate 103 that seals the locking hole 102, and the upper end surface of the cover plate 103 is flush with the upper end surface of the weighing plate 10.

[0088] Therefore, by using the locking bolt 50 to fix the supporting seat 101 and the weighing support seat 204, the connection between them is firm and easy to disassemble, so that the weighing support seat 204 and the weighing sensor (not shown) fixed therein can be replaced or maintained regularly or irregularly. At the same time, by providing the cover plate 103 to seal the locking hole 102, the locking bolt 50 is well hidden and it is not easy for external water stains to enter the locking hole 102 and flow into the weighing seat 20.

[0089] In addition, in this technical solution, continue to control Figure 2 and Figure 4 As shown, according to one embodiment of the present invention, the weighing seat 20 includes a base 20a with an open upper portion and a detachable cover 20b covering the upper opening of the base 20a;

[0090] The weighing support seat 204 is detachably fixed inside the base 20a; the first opening 201 and the second opening 202 are formed on the detachable cover 20b.

[0091] Therefore, the weighing seat 20 is configured to include a base 20a with an open upper portion and a detachable cover 20b covering the upper opening of the base 20a, so as to facilitate the installation and fixation of structural components such as the weighing instrument 30, the weighing sensor (not shown) and the weighing support seat 204 therein.

[0092] Preferably, in the present technical solution, the base 20a and the removable cover 20b are interlocked or fixed by fasteners such as fastening bolts, and the corresponding fixing methods therebetween are relatively common in the prior art, so the details thereof are not described in detail here.

[0093] Furthermore, in the specific implementation, it is still necessary to refer to Figure 2 and Figure 4 As shown, according to one embodiment of the utility model, the weighing meter 30 includes a main control circuit board 301, a main controller arranged on the main control circuit board 301, a transparent shell 302 and a weighing display screen 303 connected to the main controller;

[0094] Among them, a fixed frame 205 is arranged upwardly in the inside of the base 20a; the main control circuit board 301 is fixed in the middle part of the fixed frame 205; a plurality of support columns 206 are protruding upward from the inner periphery of the fixed frame 205; the weighing display screen 303 is mounted on the plurality of support columns 206; the transparent shell 302 is fixedly sleeved on the outside of the upper part of the fixed frame 205 to cover and fix the main control circuit board 301, the main controller and the weighing display screen 303.

[0095] Preferably, the outer periphery of the transparent housing 302 is fixed outside the fixing frame 205 by fasteners such as fixing bolts.

[0096] In this regard, it is clear that by providing the transparent shell 302 to cover and fix the main control circuit board 301, the main controller and the weighing display screen 303, on the one hand, it can play a waterproof role, so that the weighing meter 30 has a good waterproof effect. On the other hand, it can also play a certain isolation and protection role, so that the weighing meter 30 is not easily damaged by collision, etc., so that its service life is long.

[0097] Again, in the specific implementation, still refer to Figure 2 and Figure 4 As shown, according to one embodiment of the utility model, an annular step 2051 is cut inwardly on the outer wall of the fixed frame 205, and the annular step 2051 is covered with an inherent sealing ring A207. When the transparent shell 302 is fixedly sleeved on the outer part of the fixed frame 205, its inner wall is tightly against the outer wall of the sealing ring A207.

[0098] In this regard, it is clear that when the transparent shell 302 is fixed on the upper part of the fixed frame 205, its inner wall will press the outer periphery of the sealing ring A207 downward to make it tightly against the outer wall of the sealing ring A207. In this way, it is difficult for water stains that may exist on the outside to enter the interior through the upper edge of the fixed frame 205, so that the weighing meter 30 has a better waterproof effect.

[0099] Preferably, in this technical solution, Figure 5 As shown, according to one embodiment of the utility model, a wire hole A2052 is opened at the lower part of the outer wall of the fixed frame 205, and the weighing sensor (not shown) is connected to the main controller through a signal line 60 passing through the wire hole A2052, and the wire hole A2052 is filled with a sealant (not shown) to seal it.

[0100] Therefore, after the weighing sensor (not shown) is connected to the main controller through the signal line 60 passing through the wire hole A2052, a sealant (not shown) is poured into the wire hole A2052 to seal it, so that water stains that may exist on the outside cannot easily enter the fixed frame 205 through it, so that the weighing meter 30 is further less likely to be stained by water.

[0101] It should be added that in the specific implementation, Figure 2 and Figure 4 As shown, according to one embodiment of the utility model, the lower bottom surface of the base 20a is recessed upward to form a battery slot 208, and a rechargeable battery 70 for powering the main controller is installed in the battery slot 208. A battery cover 209 is detachably covered at the lower notch of the battery slot 208. A wire hole B is opened on the inner surface of the battery slot 208 and passes through the interior of the fixed frame 205. The rechargeable battery 70 is connected to the main controller via an electrical connection line passing through the wire hole B.

[0102] Preferably, the outer periphery of the battery cover 209 is fixed outside the lower notch of the battery slot 208 by fasteners such as fixing bolts.

[0103] Therefore, it can be clearly seen that the present application has its own rechargeable battery 70 to power the main controller, so that an external power cord can be omitted, making the present application convenient to use. At the same time, by setting the battery cover 209 to cover the lower notch of the battery slot 208, the rechargeable battery 70 can have a good waterproof effect.

[0104] It is further necessary to add that Figure 4As shown, in a specific implementation, according to an embodiment of the utility model, the lower notch of the battery slot 208 is cut upward to form an annular groove 2081, and a sealing ring B210 is clamped in the annular groove 2081. When the battery cover 209 is closed on the lower notch of the battery slot 208, the circumferential edge of its upper end surface is tightly against the lower bottom surface of the sealing ring B210.

[0105] Furthermore, through the above-mentioned optimized design, by setting the sealing ring B210, when the battery cover 209 is closed on the lower notch of the battery slot 208, the circumferential edge of its upper end surface will press the sealing ring B210 upward to make it tightly against the lower bottom surface of the sealing ring B210. In this way, it is difficult for water stains that may exist on the outside to enter the interior through the lower notch of the battery slot 208, so that the rechargeable battery 70 has a better waterproof effect.

[0106] It should be further added that, in a specific implementation, according to an embodiment of the present invention, a height-adjusting foot pad 211 is fixedly provided at each of the four corners of the bottom of the base 20a; the lower middle portions of the left and right sides of the base 20a are respectively concave to form a gripping portion 212 suitable for holding by hand.

[0107] Therefore, by providing a plurality of height-adjusting foot pads 211, the heights of the foot pads 211 can be adjusted to ensure the stability of the base 20a when placed on the ground, and by providing the gripping portion 212, it is convenient for the user to carry the device by hand, and the gripping and anti-falling properties are good.

[0108] It should also be added that, in the specific implementation, according to the waterproof balance scale 1000 provided in the embodiment of the utility model, the main control circuit board 301 described in the present application is also provided with a wireless connection module connected to the main controller for connecting an external intelligent device to transmit weighing data to the external intelligent device and use the external intelligent device to remotely control the weighing instrument 30 described in the present application.

[0109] Preferably, the wireless connection module adopts a WIFI module, a Bluetooth module and / or a 5G module, etc., to make the use of this application more intelligent.

[0110] It should also be added that in the specific implementation, Figure 3 and Figure 4 As shown, according to the waterproof balance scale 1000 provided in the embodiment of the utility model, the bottom surface of the base 20a is also provided with a power switch 213 connected to the main controller, and the power switch key 213 is inherently covered with a detachable waterproof bottom cover 214, so that the power switch key 213 can also have a good waterproof effect when not in use.

[0111] Other embodiments and the like are not described here by way of example.

[0112] In summary, the waterproof balance scale 1000 provided by the present application, in specific implementation, since the first opening 201 is fixed with a waterproof panel 40 closely attached to the weighing meter 30, it is possible to better prevent water stains and the like from entering the weighing seat 20 through the first opening 201, so that the weighing meter 30 fixed in the weighing seat 20 and located below the first opening 201 is not easily soaked in water and burned. In addition, since the upper end surface of the weighing seat 20 is provided with at least one circle of waterproof guardrail 203 protruding upward around the second opening 202, the waterproof guardrail 203 is provided to intercept external water stains and the like from entering the weighing seat 20 through the second opening 202, so that the weighing sensor (not shown) fixed in the weighing seat 20 and located below the second opening 202 is not easily soaked in water and burned.

[0113] At the same time, by providing the transparent shell 302 to cover and fix the main control circuit board 301, the main controller and the weighing display screen 303, with the support of the sealing ring A207, on the one hand, it can play a waterproof role, so that the weighing meter 30 has a good waterproof effect. On the other hand, it can also play a certain isolation and protection role, so that the weighing meter 30 is not easily damaged by collision, etc., so that its service life is long.
