Description

Built-in keel structure of burglary-resisting door Technical Field The utility model relates to the technical field of keels, in particular to a built-in keel structure of a burglary-resisting door. Background The built-in keel of the burglarproof door is a structural support material made of metal (such as steel or aluminum alloy), is positioned inside the door and distributed along the periphery of the door frame and the door plate, and aims to enhance the strength, tensile property and overall stability of the door. Through the design, the keels can effectively resist damage means such as external impact and lock picking, and the safety and durability of the anti-theft door are obviously improved. The specific design and layout of the anti-theft door can be adjusted according to the requirements of different anti-theft door models so as to ensure the optimal protection effect. At present, the keels of the burglary-resisting doors in the market are fixed and spliced in a field welding mode, and the mode is simple to operate, but has obvious limitations. Firstly, the technical requirements of field welding on workers are high, the welding quality directly influences the strength of a keel and the overall safety of the burglary-resisting door, secondly, the welding process is long in time consumption, and particularly, the production efficiency is low under the condition of needing multi-point welding or complex structures. Disclosure of utility model The utility model provides an anti-theft door built-in keel structure which aims to solve the defects in the prior art. In order to achieve the aim, the utility model adopts the following technical scheme that the built-in keel structure of the burglary-resisting door comprises two side square tubes, wherein an upper square tube, a plurality of middle square tubes and a lower square tube are sequentially arranged between the two side square tubes from top to bottom; Two inserting blocks are symmetrically and fixedly connected to the bottom of the upper square pipe, the tops of the plurality of middle square pipes and the tops of the lower square pipes, limiting slots are sleeved on the outer surfaces of the plurality of inserting blocks, and the limiting slots are fixedly connected with the adjacent side square pipes; The outer surface side of a plurality of middle side pipe is all symmetry fixed scarf joint has two C shaped steel, and is a plurality of joint in the C shaped steel is equipped with the elastic component jointly, two the equal fixedly connected with of surface one side of elastic component a plurality of inserted bars, and spacing grafting between inserted bar and the adjacent spacing slot, the inserted block. Further, a plurality of first spacing jacks penetrating to the other side are all arranged on one side of the outer surface of the inserting block, and the first spacing jacks are matched with the inserting rods. Further, a second limiting jack penetrating through to the other side is formed in one side of the outer surface of each limiting slot, and the second limiting jacks are matched with the inserting rods. Further, two the elastic component all includes a plurality of square boards, and the square board is located the inboard of adjacent C shaped steel, and is a plurality of the equal fixedly connected with spring in surface one side of square board, a plurality of the other end of spring is fixedly connected with fly leaf jointly, surface one side fixedly connected with a plurality of connecting plates of fly leaf, and connecting plate and adjacent inserted bar fixed connection.
