Description

Technical Field

[0001] The invention belongs to the technical field of lead-acid batteries, and in particular relates to a colloid valve capable of preventing loose tightening. Background Art

[0002] Valve-controlled sealed lead-acid batteries are widely used due to their maintenance-free features. Maintenance-free batteries require excellent battery sealing to prevent acid (acid mist) and water loss that lead to premature termination of life. At the same time, acid leakage and acid emission during use can easily cause short circuits, corrosion, and fires.

[0003] The difficulty of adding gel to colloidal lead-acid batteries is higher than that of ordinary lead-acid batteries, so the colloidal battery valve port design is larger than that of ordinary lead-acid batteries, and a special colloidal battery safety valve (hereinafter referred to as the colloidal valve) is used for sealing, and the colloidal valve itself has a labyrinth design, which has better water loss prevention ability than directly using a safety valve seal. However, the colloidal valve is often not screwed in place during use, which makes the battery prone to acid leakage during use. Summary of the invention

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a colloid valve that prevents loose tightening, the colloid valve comprising a valve body and a colloid valve sleeve, the colloid valve sleeve is arranged on the outer surface of the valve body, a cover structure is arranged on the top of the outer surface of the valve body, a buckle is arranged on the valve body sleeve, and an indicator structure is arranged on the cover structure.

[0005] Based on the above technical features, the main function of the present invention is to intuitively judge whether the colloid valve is tightened, and effectively reduce the undesirable phenomenon of battery acid leakage caused by the colloid valve not being tightened.

[0006] As an improvement of the present utility model, the indicating structure is a concave structure or a convex structure.

[0008] As an improvement of the present invention, the indicating structure is an arrow structure, and the arrow structure is arranged at two diagonal sides of the cover sheet, and the arrow structure is distributed in a straight line. In the present invention, the tip of the convex arrow structure can also be set as a soft structure or the top surface of the arrow structure can be covered with a soft structure as a whole, so as to avoid the situation that the tip of the arrow structure is damaged and missing, which affects the judgment of the operator.

[0009] Based on the above technical features, a pair of arrows are designed on two diagonals of the top surface of the colloid valve housing. When the colloid valve is screwed onto the battery cover, it can be determined whether the colloid valve is tightened by observing the direction of the arrows.

[0010] As an improvement of the utility model, the arrow structure is provided with a color indicating coating.

[0011] Based on the above technical features, according to the above, the color indication coating of the arrow structure is a same color coating, the colors of the two arrows are the same color, and are not the same color as the cover sheet, which can help the operator make clear and quick judgments.

[0012] As an improvement of the utility model, the arrow structure is provided with a luminous indicating coating.

[0013] Based on the above technical features, according to the above, the luminous indication coating can help operators make clear and quick judgments in poor visibility or at night, thereby improving work efficiency.

[0014] As an improvement of the utility model, the outer layer of the colloid valve outer sleeve is further provided with a rubber ring.

[0015] As an improvement of the utility model, buckle limiting teeth are arranged on the outer side of the colloid valve housing.

[0016] Based on the above technical features, the valve is screwed to a horizontal position in the direction of the arrow, and the buckle limit teeth exceed the buckle, thereby limiting the rotation of the valve.

A pair of arrows are designed at two diagonals on the top surface of the colloid valve housing 2. When the colloid valve is screwed on the battery cover, it can be judged whether the colloid valve is tightened by observing the direction of the arrows. For example, after all six valves of a 12V battery are screwed on, 12 arrows form a straight line, which is parallel to the straight line formed by the positive and negative terminals.

[0029] As an improvement of this embodiment, the arrow structure 601 is provided with a color indicating coating 602. According to the above, the color indicating coating 602 of the arrow structure 601 is a same color coating, and the colors of the two arrows are the same color, and are not the same color as the cover sheet 5, which can help the operator to make a clear and quick judgment.
