Fire door lock catch

Technical Field

The utility model relates to a fire door hasp technical field specifically is a fire door hasp.

Background

The fire box is a fire-fighting device for accommodating fire-fighting tools, and when a fire is found, the fire box is opened to take out the fire-fighting tools for fire extinguishment; the structure of the door lock generally comprises a box body and a door arranged on the box body, wherein the door is hinged with the box body, and the door is generally provided with a lock catch by screw fixation.

At present, the existing fire-fighting door lock catch is generally disassembled and assembled by using screws and disassembling tools, so that the labor intensity of operators when the lock catch is disassembled and assembled is increased, and the convenience of the fire-fighting door lock catch in the replacing process is reduced. For this reason, new technical solutions need to be designed to solve the problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a fire door hasp has solved the problem that proposes in the background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a fire door hasp, includes the hasp casing, the upper surface of hasp casing is provided with the installation casing, be provided with linkage plate and logical groove on the installation casing, linkage plate fixed connection be in one side of installation casing upper surface, it runs through to lead to the groove the both ends of installation casing, all be equipped with plastics buckle one on the upside inner wall at the both ends that lead to the groove, the both sides of installation casing all are equipped with and lead to the recess of groove intercommunication, be equipped with plastics buckle two on the recess upside inner wall.

Compared with the prior art, the technical scheme has the advantages that the lock catch is effectively installed on the fire door through the first plastic buckle plate and the second plastic buckle plate in an assembled clamping mode, the lock catch is prevented from being disassembled and assembled through screws and disassembling tools, labor intensity of operators is reduced when the lock catch is disassembled and assembled, and convenience of the fire door lock catch in a replacing process is improved.

As an alternative of the technical solution of the present application, the mounting housing is welded in the middle of the upper surface of the latch housing.

Through adopting above-mentioned technical scheme, improved the whole effect between installation casing and the hasp casing.

As an optional scheme of this application technical scheme, plastics buckle one size with lead to the groove the size identical, and with the inner wall swing joint who leads to the groove, two sizes of plastics buckle with the size of recess is identical, and with the inner wall swing joint of recess.

By adopting the technical scheme, the first plastic buckle plate and the second plastic buckle plate can be conveniently stretched and contracted in the through grooves and the grooves

As an alternative of this application technical scheme, the recess is located the side middle part position of installation casing, be equipped with on the installation casing upper surface with two complex of plastics buckle and with the opening that leads to the groove intercommunication one, the one end of keeping away from the connection board on the installation casing upper surface is equipped with a complex of plastics buckle and with the opening two that lead to the groove intercommunication.

By adopting the technical scheme, the arrangement of the first opening and the second opening is favorable for inward deformation of the first plastic buckle plate and the second plastic buckle plate in the clamping process.

Drawings

Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:

FIG. 1 is a first schematic structural view of a fire door latch of the present invention;

FIG. 2 is a first schematic structural view of a fire door lock of the present invention;

fig. 3 is a schematic view of the plastic buckle structure of the fire door lock of the present invention.

In the figure: 1. a latch housing; 11. installing a shell; 12. a connector tile; 13. a through groove; 14. a first plastic buckle plate; 15. a second opening; 16. a first opening; 17. a groove; 18. and a plastic buckle plate II.

Detailed Description

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a fire door hasp, includes hasp casing 1, the upper surface middle part welding of hasp casing 1 has installation casing 11, be provided with linkage plate 12 and logical groove 13 on the installation casing 11, linkage plate 12 fixed connection is in one side of installation casing 11 upper surface, it runs through to lead to groove 13 the both ends of installation casing 11, all be equipped with plastic buckle 14 on the upside inner wall at logical groove 13's both ends, the both sides of installation casing 11 all are equipped with and lead to the recess 17 of groove 13 intercommunication, be equipped with plastic buckle two 18 on the recess 17 upside inner wall.

The size of the first plastic buckle plate 14 is matched with that of the through groove 13 and is movably connected with the inner wall of the through groove 13, and the size of the second plastic buckle plate 18 is matched with that of the groove 17 and is movably connected with the inner wall of the groove 17.

The groove 17 is located in the middle of the side face of the installation shell 11, a first opening 16 which is matched with the plastic buckle plate II 18 and communicated with the through groove 13 is formed in the upper surface of the installation shell 11, and a second opening 15 which is matched with the plastic buckle plate I14 and communicated with the through groove 13 is formed in one end, far away from the connecting plate 12, of the upper surface of the installation shell 11.

When the concrete implementation is carried out again: when the fire door lock catch is installed, an operator directly inserts the installation shell into the preformed groove of the fire door, the first plastic buckle plates 14 at the two ends of the installation shell and the second plastic buckle plates 18 at the two sides can stretch inwards, and then the installation shell stretches out and is clamped at the edge of the preformed groove on the inner surface of the fire door when completely entering the preformed groove;
