Description

The battery safety valve of band swing angle location

Technical field

The utility model relates to a kind of battery safety valve with the swing angle location, refers to a kind of completely-sealed lead-acid battery safety valve that is used for transport process such as highway, railway and navigation channel especially.

Background technology

At present, domestic completely-sealed lead-acid battery safety valve adopts rubber washer to add the hermetically-sealed construction of independent valve body mostly, mainly exists two problems:

1) if. twist De Taisong, in vibration, can jump, and may cause battery valve to leak and the battery failure problem;

2) if. twist too tightly, independent valve body may break, and can cause battery valve to leak and the battery failure problem equally;

How to address this problem is the main task that we need consider.

Summary of the invention

In order to overcome above-mentioned weak point, main purpose of the present utility model aims to provide and a kind ofly can prevent thread looseness, can avoid leaking because of battery valve the battery safety valve of the band swing angle location that makes battery failure again.

The technical problems to be solved in the utility model is: solve because of twist De Taisong or twist the valve body that too tightly the causes problem of can breaking; Solve because of battery valve and leak relevant technologies problems such as making battery failure.

The technical scheme that its technical problem that solves the utility model adopts is: this device is made up of parts such as valve body, rubber washer and battery valves, on independent valve body, be provided with rubber sheet gasket, battery case internal thread successively, tighten swing angle location and non-return swing angle location, wherein:

The battery case internal thread is connected with lid, the non-return swing angle is positioned at by the side of tightening the swing angle location, independent valve body, rubber sheet gasket, battery case internal thread, tighten swing angle location and non-return swing angle and be located by connecting on an integral plastics and annotate on the part, its integral plastics is annotated part has battery to cooperate shell outward, it is the battery case outside that battery cooperates a side of shell, and it is battery case inside that battery cooperates the opposite side of shell.

The side of the non-return swing angle location of the battery safety valve of described band swing angle location is provided with protruding place, withstands the battery case internal thread during its distortion.

The beneficial effects of the utility model are: when battery safety valve is tightened, tightening swing angle location can limit safety valve and further tighten, when battery safety valve will become flexible because of vibration, non-return swing angle location can prevent that safety valve from getting loose, effectively prevent the battery safety valve thread looseness, can guarantee the advantages such as inner sealing of battery.

Embodiment

See also shown in the accompanying drawing 1,2,3,4,5, the utility model is made up of parts such as valve body, rubber washer and battery valves, on independent valve body (1), be provided with rubber sheet gasket (2), battery case internal thread (3) successively, tighten swing angle location (4) and non-return swing angle location (5), wherein:

Battery case internal thread (3) is connected with lid, non-return swing angle location (5) is positioned at by the side of tightening swing angle location (4), independent valve body (1), rubber sheet gasket (2), battery case internal thread (3), tighten swing angle location (4) and non-return swing angle location (5) and be connected an integral plastics and annotate on the part, its integral plastics is annotated part has battery to cooperate shell (6) outward, it is battery case outside (7) that battery cooperates a side of shell (6), and it is battery case inside (8) that battery cooperates the opposite side of shell (6).

The side of the non-return swing angle location (5) of the battery safety valve of described band swing angle location is provided with protruding place, withstands battery case internal thread (3) during its distortion.

Operation principle of the present utility model is:

As shown in Figure 1, when battery safety valve is tightened, tighten swing angle location (4) restriction safety valve and further tighten;

As shown in Figure 4, when battery safety valve will become flexible because of vibration, non-return swing angle location (5) prevented that safety valve from getting loose;

When battery safety valve was tightened, non-return swing angle location (5) made the entire cell safety valve can enter above-mentioned Fig. 1 position distortion;

After battery safety valve is tightened, do not use special instrument can't turn on safety valve; Can cause non-return swing angle location (5) fracture failure if turn on battery safety valve by force.

Structure of the present utility model is utilized the deformable characteristic of plastics dexterously, by non-return swing angle location (5) distortion and rubber sheet gasket (2) distortion, makes separate valves enter position shown in Figure 1.Because when separate valves entered, non-return swing angle location (5) did not have destroyed, in transportation, screw thread will become flexible, and battery case internal thread (3), position as shown in Figure 4 will be withstood in non-return swing angle location (5).Effectively prevent the battery safety valve thread looseness, guaranteed the inner sealing of battery.
