In one embodiment, the outer side of the circumference of the connecting ring is externally protruded with a first convex part, and the inner side of the waterproof sleeve is provided with a first clamping part matched with the first convex part.

In one embodiment, the outer side of the circumference of the connecting ring is externally protruded with a second convex part, an inwards concave sealing waterproof area is formed between the first convex part and the second convex part, and the inner side of the waterproof sleeve is provided with a second clamping part matched with the second convex part.

In one embodiment, the connecting ring is fixedly attached to the outer side of the sensor body through waterproof glue.

In one embodiment, a groove is concaved inwards at the edge of the inner side of the connecting ring, which is close to the end part of the sensor body, and a connecting cavity for filling waterproof glue is formed between the groove and the outer wall of the sensor body.

In one embodiment, the waterproof jacket is a silicone membrane.

In summary, compared with the prior art, the utility model has the following beneficial effects:

the two connecting rings are matched with the waterproof sleeve to form the local middle section of the sensor body to be waterproof, so that the situation that the waterproof structure such as a sealing ring is not waterproof in place due to deformation and inward seepage occurs in the mounting hole is effectively avoided; and go up the mode of rubber coating with the sensor body and need not to be connected through mechanical component, as long as guarantee the rubber coating in place in production, then, the whole waterproof of this application will be effective for a long time.

Detailed Description

The utility model is further described in the following description and detailed description with reference to the drawings:

as shown in fig. 1 to 2, an embodiment of the present utility model preferably provides a waterproof sealing structure of a weighing sensor, which includes a sensor body 1, two ends of the sensor body 1 are respectively provided with mounting holes 2, two connecting rings 3 are fixedly arranged on the sensor body 1 between the two mounting holes 2 at intervals, and a waterproof sleeve 4 for wrapping the sensor body 1 is connected between the two connecting rings 3. Specifically, through two go-between and waterproof cover cooperation to form the local middle section of sensor body waterproof, thereby effectively avoid waterproof structure such as sealing washer deformation to lead to waterproof not in place, take place the condition of inwards oozing liquid at the mounting hole site.

Further, the outer side of the circumference of the connecting ring 3 is externally protruded with a first convex part 31, and the inner side of the waterproof sleeve 4 is provided with a first clamping part 41 matched with the first convex part 31. Specifically, a clamping structure of the waterproof sleeve sleeved on the connecting ring is formed by the first convex part and the first clamping part of the waterproof sleeve, so that the waterproof sleeve and the connecting ring are connected and fixed; and waterproof glue can be filled and coated between the waterproof sleeve and the connecting ring according to requirements, so that the waterproof sleeve and the connecting ring can be sealed and fixed.

Further, a second protrusion 32 is protruded outside the circumference of the connection ring 3, a concave sealing waterproof area 33 is formed between the first protrusion 31 and the second protrusion 32, and a second clamping portion 42 matched with the second protrusion 32 is provided inside the waterproof sleeve 4. Specifically, a clamping structure of the waterproof sleeve sleeved on the connecting ring is formed by the second convex part and the second clamping part of the waterproof sleeve, so that the waterproof sleeve and the connecting ring are connected and fixed; the first convex part and the second convex part are matched to form a double sealing structure, so that the condition of seepage is effectively avoided, and the waterproofness is enhanced; and waterproof glue can be filled and coated between the waterproof sleeve and the connecting ring according to requirements, so that the waterproof sleeve and the connecting ring can be sealed and fixed.
