Technical Field

The utility model relates to the technical field of batteries, concretely relates to outer stopper structure PVC battery is with tieing a structure.

Background

At present, the general zinc-manganese batteries can be classified into two types according to the materials of the trademarks used outside the batteries. One type of battery is a PVC battery, and the other type of battery is an iron-clad battery. The iron-clad battery is generally a battery with an external plug structure, wherein the sealing ring is arranged outside relative to the zinc cylinder. The design makes full use of the effective space of the battery; meanwhile, the explosion-proof effect of the battery can be achieved. However, the sealing ring of the PVC battery is generally placed in the zinc can, and the sealing ring of the battery not only occupies the effective space in the zinc can, but also is more complicated to manufacture in order to achieve the explosion-proof index.

In the related art, the design of the PVC battery with the outer plug structure is assumed, and the sealing ring is arranged externally but an iron shell structure is not used. In order to ensure the stability and the explosion-proof capability of the battery structure, a new structure which can replace an iron shell in function needs to be designed for the PVC battery with the outer plug structure.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a stick structure that is used for outer stopper structure PVC battery on, can guarantee battery structural stability and explosion-proof ability.

The technical scheme of the utility model be, provide an outer stopper structure PVC battery is with propping up a strip structure, including being used for entangling the circle of propping up of the positive terminal cap of battery to and two at least wherein one end is fixed it is used for fixing the strip of propping up a strip on battery negative pole bottom to prop up the other end on the circle.

Furthermore, one surface of the tightening ring is provided with an annular clamping ring for clamping a battery positive electrode cap, and the annular clamping ring and the tightening ring are coaxial.

Further, one end, far away from the circle, of the tightening strip is provided with a circular welding ring.

Preferably, four bars are arranged and fixed on the periphery of the snare in a uniformly distributed manner.

Furthermore, a plurality of reinforcing ribs are arranged on the outer side surface of the rib, and the extending direction of the reinforcing ribs is perpendicular to the extending direction of the rib.

Preferably, the tie bars are metal bars.

The utility model discloses technical scheme's beneficial effect does: by providing a rib structure with ribs and loops, one end of the rib is fixed on the rib. When the battery is assembled, the tightening ring is sleeved on and hoops the positive electrode cap of the battery, the tightening strips at the two ends of the tightening ring are bent by 90 degrees and then are tightly attached to the zinc cylinder of the battery, and finally the end parts of the tightening strips are fixed on the negative electrode bottom of the battery. The whole strip structure of tightening forms the iron-clad structure of similar iron-clad battery, nevertheless for iron-clad structure consumptive material few with low costs, the outer stopper structure PVC battery structural stability and the blast resistance that make are all comparatively excellent.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.

FIG. 1 is a schematic structural diagram of a tie bar structure for a PVC battery with an external plug structure;

fig. 2 is a schematic structural diagram of a tie bar structure for a PVC battery with an external plug structure.

Wherein the reference numbers are:

1. a tightening ring, 2, a tightening strip, 3, an annular clamping ring, 4, a circular welding ring, 5 and a reinforcing rib.

Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

Referring to fig. 1 and 2, the present invention provides a tie bar structure for PVC battery with external plug structure, which includes a tie ring 1 for covering the positive electrode cap of the battery, and at least two tie bars 2, one end of which is fixed on the tie ring 1 and the other end of which is fixed on the negative electrode bottom cap of the battery.

Specifically, by providing a rib structure with ribs 1 and 2, one end of each rib 2 is fixed on the rib 1. When the battery is assembled, the tightening ring 1 is sleeved on and hoops the positive electrode cap of the battery, the tightening strips 2 at two ends of the tightening ring 1 are bent by 90 degrees and then are tightly attached to the zinc cylinder of the battery, and finally the end parts of the tightening strips 2 are fixed on the negative electrode bottom of the battery. The whole strip structure of tightening forms the iron-clad structure of similar iron-clad battery, nevertheless for iron-clad structure consumptive material few with low costs, the outer stopper structure PVC battery structural stability and the blast resistance that make are all comparatively excellent.

In one implementation mode, one surface of the fastening ring 1 is provided with an annular clamping ring 3 for clamping a battery positive electrode cap, and the annular clamping ring 3 is coaxial with the fastening ring 1.

In particular, in this design, the annular collar 3 enhances the stability of the overall tie bar structure by clamping on the battery positive cap, but accordingly it is necessary to provide an annular slot corresponding to the annular collar 3 on the battery positive cap.

In another implementation, the end of the rib 2 remote from the snare 1 is provided with a circular welding ring 4. In this embodiment, it can be the metal strip to draw strip 2, draws the fixed mode of strip 2 on the battery negative pole bottom to be the welding, and circular welding ring 4 is provided with and does benefit to and reduces the welding degree of difficulty for welding efficiency.

Preferably, four bars 2 are provided, and four bars 2 are uniformly distributed and fixed on the periphery of the snare 1. In this embodiment, the tie bar 2 is a long straight bar, and as other feasible design modes, the tie bar 2 may also be X-shaped or have an annular middle with two elongated ends, so that the contact area between the tie bar 2 and the battery zinc can be increased, and the explosion-proof effect of the tie bar 2 can be enhanced.

As a modification, a plurality of ribs 5 are disposed on the outer side surface of the rib 2, and the extending direction of the ribs 5 is perpendicular to the extending direction of the rib 2.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
