TECHNICAL FIELD

[0001] The utility model relates to the field of labor protection appliance, especially a battery seat fixing structure of automatic light filtering filter for protection during welding. BACKGROUND

[0002] Automatic light filtering filter is a device that can automatically adjust brightness following light changes when welding mask is used for welding operation, so as to provide protection for welder's glasses from strong light. In the industry, automatic light filtering filter is usually called ADF.

[0003] The battery seat of the automatic light filtering filter on the market is fixed on the frame of ADF by multiple fixing screws, at least four screws are needed to fix around it first, and then the upper and lower shells are clamped and installed, which is relatively cumbersome to install and disassemble, and the manufacturing cost is high. SUMMARY

[0004] The utility model provides a kind of automatic light filtering filter's battery seat fixing structure that is convenient to install and disassemble and low in cost.

[0005] To solve the above technical problems, the technical scheme adopted by the utility model is as follows:

[0006] A battery seat fixing structure of an automatic light filtering filter, comprising a core box lower cover and a core box upper cover. A circuit board and a light valve assembly are clamped between the core box lower cover and the core box upper cover. The core box lower cover has a battery seat compartment. A battery seat is fixedly installed in the battery seat compartment. The battery seat is electrically connected to the circuit board. One side of the battery seat abuts against the inner wall of the battery seat compartment corresponding to the battery seat compartment. A screw passes through the core box lower cover and abuts against the other side of the battery seat.

[0007] Further, one side of the battery seat has a recess, and the battery seat compartment has a corresponding protrusion. The protrusion on the battery seat compartment abuts against the recess on the battery seat. The other side of the battery seat also has a positioning groove. The front end of the screw passes through the core box lower cover and abuts against the positioning groove of the battery seat.

[0008] Further, a nut is installed on the core box lower cover. The screw is threadedly connected to the battery seat through the nut.

[0009] Further, one end of the screw is also provided with a stop.

[0010] Further, the tail end of the screw has a tool groove, and the rear end of the screw does not protrude from the surface of the core box lower cover after being tightened.

[0011] Compared with the prior art, the battery holder fixing structure of the automatic light filter has the beneficial effects that: the battery holder is fixed in up-down and left-right directions by the battery holder warehouse corresponding to the inner wall of one side of the battery holder and the screw passing through the lower cover of the core box and abutting against the other side of the battery holder, and the core box upper and lower shells are clamped to fix the battery holder in front and back directions, so that the battery holder is fixed conveniently and simply, and the cost is reduced by the simple structure.

DETAILED DESCRIPTION

[0016] The following is based on the ideal embodiment of the present application, through the following description, the relevant staff can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content of the specification, and must be determined by the scope of the claims.

[0017] The present application is further described with reference to the following drawings:

[0018] As shown in Figure 1 , 2 , a battery holder fixing structure of an automatic light filter, comprising a lower cover of a core box 1 and an upper cover of the core box 2; the circuit board 3 and the light valve assembly 4 are clamped between the lower cover of the core box 1 and the upper cover of the core box 2, characterized in that: the lower cover of the core box 1 has a battery holder warehouse 1-1, the battery holder 5 is fixedly installed in the battery holder warehouse 1-1, the battery holder 5 is electrically connected with the circuit board 3, one side of the battery holder 5 abuts against the inner wall corresponding to the battery holder warehouse 1-1, and the screw 6 passes through the lower cover of the core box 1 and abuts against the other side of the battery holder 5. In the specific implementation process of the present application, the lower cover of the core box 1 and the upper cover of the core box 2 are finally clamped and installed, so that the battery can be conveniently replaced.

[0019] The battery holder 5 has a recess 5-1 on one side and a corresponding protrusion 1-1-1 on the battery holder compartment 1-1, the protrusion 1-1-1 on the battery holder compartment 1-1 is in abutment with the recess 5-1 on the battery holder 5; the other side of the battery holder 5 also has a positioning groove 5-2, the front end of the screw 6 is in abutment with the positioning groove 5-2 of the battery holder 5 by penetrating the core box lower cover 1.
