Description

Technical Field

[0001] The utility model relates to the technical field of battery safety valves, in particular to a 1E-level anti-loosening safety valve structure. Background Art

[0002] Most of the current safety valves use boss interference fit, and then the safety valve is screwed onto the battery cover through the valve lever.

It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0023] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0026] Combined with Figure 1-4 , a 1E-level anti-loosening safety valve structure of the present embodiment comprises a battery cover 1 and a safety valve 2, the battery cover 1 is provided with a connecting groove 3 for connecting the safety valve 2, the safety valve 2 is assembled in the connecting groove 3, at least one first wedge-shaped boss 4 is provided on the outer peripheral wall of the safety valve 2, the first wedge-shaped boss 4 extends along the radial direction of the safety valve 2, and at least one second wedge-shaped boss 5 is provided on the inner peripheral wall of the connecting groove 3, the first wedge-shaped boss 4 and the second wedge-shaped boss 5 are abutted along the axial direction of the safety valve 2, the second wedge-shaped boss 5 is arranged relative to the first wedge-shaped boss 4 close to the opening side of the connecting groove 3, the abutment of the first wedge-shaped boss 4 and the second wedge-shaped boss 5 is used to limit the safety valve 2 from coming out of the connecting groove 3, the first wedge-shaped boss 4 and the second wedge-shaped boss 5 are connected by an anti-slip structure, and the anti-slip structure is used to improve the abutment stability of the first wedge-shaped boss 4 and the second wedge-shaped boss 5.

[0027] The 1E-level anti-loosening safety valve structure achieves anti-loosening cooperation through the cooperation between the first wedge-shaped boss 4 and the second wedge-shaped boss 5, and avoids the failure of the abutment between the first wedge-shaped boss 4 and the second wedge-shaped boss 5 through the cooperation between the first wedge-shaped boss 4 and the second wedge-shaped boss 5, thereby playing the role of anti-loosening limit.

[0028] As an optional solution of the present utility model, the anti-slip structure includes an anti-slip groove 6, which is provided on the first abutting inclined surface 4a of the first wedge-shaped boss 4; an anti-slip portion 7, which is provided on the second abutting inclined surface 5a of the second wedge-shaped boss 5; when the first wedge-shaped boss 4 and the second wedge-shaped boss 5 are abutted and matched, the first abutting inclined surface 4a and the second abutting inclined surface 5a are abutted and matched, and the anti-slip portion 7 is clamped in the anti-slip groove 6 to limit the relative movement of the first wedge-shaped boss 4 and the second wedge-shaped boss 5, thereby achieving the purpose of anti-slip.

[0029] In other embodiments, the anti-slip structure includes the anti-slip groove 6 and the anti-slip portion 7 on the first wedge-shaped boss 4 and the second wedge-shaped boss 5, and the positions thereof are interchangeable.

[0030] As an optional solution of the present invention, a limit stop block 8 is provided at one end of the first wedge-shaped boss 4, and the limit stop block 8 is arranged on the higher side of the first abutting inclined surface 4a of the first wedge-shaped boss 4. The limit stop block 8 protrudes from the first abutting inclined surface 4a and abuts against one end of the second wedge-shaped boss 5, which can prevent excessive force from being applied during the knob turning process, causing the first wedge-shaped boss 4 and the second wedge-shaped boss 5 to disengage and screw off, thereby destroying the safety valve.

[0031] As an optional solution of the present invention, a contact feedback baffle 9 is provided at one end of the first wedge-shaped boss 4, and the contact feedback baffle 9 is arranged on the lower side of the first abutting inclined surface 4a of the first wedge-shaped boss 4. The contact feedback baffle 9 is not connected to the first wedge-shaped boss 4, and one side of the contact feedback baffle 9 is connected to the outer peripheral wall of the safety valve 2. The contact feedback baffle 9 protrudes from the first abutting inclined surface 4a and contacts with the second abutting inclined surface 5a. During the tightening process, the contact feedback baffle 9 contacts with the second abutting inclined surface 5a, which will produce obvious feedback to the user, and play an anti-loosening role when the first wedge-shaped boss 4 and the second wedge-shaped boss 5 are abutted and matched.

[0032] As an optional solution of the present invention, the anti-slip portion 7 is a triangular structure with an arc-shaped sharp corner, and the arc-shaped sharp corner is mainly to prevent damage to the first abutting inclined surface 4a or the second abutting inclined surface 5a.

[0033] As an optional solution of the present invention, the safety valve 2 is provided with four rectangular holes on its outer peripheral wall near its bottom, so as to facilitate the subsequent expansion of the hydrogen-oxygen composite valve.

[0034] As an optional solution of the present invention, the bottom of the safety valve 2 is provided with four circular pits, which are convenient for installation using a valve lever.

[0035] As an optional solution of the present invention, an explosion-proof disc is installed at the bottom and the top of the safety valve 2, which can greatly enhance the safety performance of the safety valve.

[0036] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
