[0006] As a further description of the above technical solution:

[0007] The outer side of the rubber strip is arranged flush with the outer side surface of the base shell.

[0008] As a further description of the above technical solution:

[0009] A vertical body is arranged at the lower part of the inner rubber sealing strip.

[0010] As a further description of the above technical solution:

[0011] The vertical body is arranged to be closely attached to the inner wall of the base shell.

[0012] As a further description of the above technical solution:

[0013] The upper portion of the inner rubber sealing strip is in an arc shape.

[0014] As a further description of the above technical solution:

[0015] The upper arc surface of the inner rubber sealing strip is located above the rubber strip.

[0016] Compared with the prior art, the utility model provides a weighing instrument waterproof structure, which has the following beneficial effects:

[0017] 1. In the utility model, a rubber strip is installed on the top of the base shell, and the top sealing plate is pressed down and fixed on the rubber strip to improve the sealing performance;

[0018] 2. In the utility model, an inner rubber sealing strip is arranged inside the rubber strip. The inner rubber sealing strip can be pressed downward and deformed by the sealing plate, but has a self-resetting upward movement function and can be tightly adhered to the sealing plate to further increase the sealing performance.

[0022] 1. Base shell; 2. Rubber strip; 3. Inner rubber sealing strip; 4. Threaded hole; 5. Rubber surface. DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] See also Figure 1-Figure 2 The utility model provides a waterproof structure of a weighing instrument, including a base shell 1, a rubber strip 2 is fixedly installed at the opening position of the base shell 1, the rubber strip 2 is located at the inner side of the base shell 1 and is integrally connected to an inner rubber sealing strip 3, threaded holes 4 are arranged at intervals on the opening of the base shell 1, the rubber strip 2 is provided with through holes connected to the threaded holes 4, and a rubber surface 5 is provided on the upper surface of the inner rubber sealing strip 3.

[0026] Specifically, Figure 1 As shown, the outer side of the rubber strip 2 is flush with the outer side of the base shell 1, and a vertical body is provided at the lower part of the inner rubber sealing strip 3. The vertical body is attached to the inner wall of the base shell 1. After the inner rubber sealing strip 3 is pressed down, it will rebound upward with the support of the vertical body.

[0027] Specifically, Figure 1 As shown, the upper portion of the inner rubber sealing strip 3 is arc-shaped, and the upper arc surface of the inner rubber sealing strip 3 is located above the rubber strip 2. The upper arc surface extends out and is pressed down. The greater the deformation, the greater the rebound force, and the tighter the rubber surface 5 is adhered.

[0028] Working principle:

[0029] A through hole is opened on the top sealing cover of the weighing instrument corresponding to the threaded hole 4, and then the sealing cover is pressed toward the base shell 1 and placed. The anti-sticking film strip on the rubber surface 5 is torn off. When the sealing cover is pressed down, the rubber surface 5 is pressed down. The inner rubber sealing strip 3 has a certain rebound recovery performance due to its shape. The inner rubber sealing strip 3 will push the sealing plate upward, and the rubber surface 5 is adhered and fixed to the sealing plate. At the same time, screws are installed at the through hole position, and the screws are tightened and fixed to the threaded hole 4 to realize the sealing and waterproof installation of the sealing cover.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
