Description
Technical field
The utility model belongs to the technical field of file cabinet, relates to a kind of top cover mounting structure of file cabinet.
Background technology
Existing file cabinet roughly has two kinds of forms, and a kind of for fixing welding, not removable formula, the characteristics of this structure are: be connected firmly, durable, its shortcoming is: packed and transported is very inconvenient, and especially the carrying of mass file cabinet more bothers; Another kind of file cabinet is dismantled and assembled file cabinet, and this structure generally all adopts screw and pin to fix because can split so be convenient to the packing carrying between top cover in this file cabinet and base plate and the left side plate.
Now be mounting structure and the process that example specifies top cover with the top cover, the left and right edges of top cover has the lower hem of downward extension, the edge, front and back of top cover has the kink that bends inwards downwards, side plate top has the interior flanging that bends inwards, wherein, have circular perforations on the lower hem, have the screwed hole portion relative on the interior flanging with circular perforations, during installation, need two people to cooperate, wherein a people keeps top cover to remain being in horizontal installation site, an other people enters after circular perforations is passed with screw in cabinet inside in the screwed hole portion on the invagination limit, screw screw with screwdriver again, so that the interior flanging of the lower hem of top cover and side plate is fastening, simultaneously, the antemarginal kink of top cover is shelved on the upper surface of backboard, the side plate of general configuration file cabinet is all thinner, so it is unpractiaca directly opening screwed hole on the interior flanging of side plate, generally can on interior flanging, have a circular mounting hole, again in installing hole with a tubular rivet that is threaded the hole in the riveting gun riveted joint, to increase the degree of depth of screwed hole portion, guarantee that being threaded of screw is firm.
The mounting structure of above file cabinet top cover needs two people to cooperate when mounted could realize installing therefore installation inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is the mounting structure that a kind of file cabinet is provided at above-mentioned prior art present situation, and this mounting structure has advantage easy for installation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of mounting structure of file cabinet top cover, this top cover is removably mounted on by left plate, the removably connect top of the U-shaped framework that forms of right plate and backboard, the left side of top cover, right hand edge has the lower hem that bends inwards respectively downwards, have perforation on each lower hem, a left side, right plate top all has the interior flanging that bends inwards, have the screwed hole portion relative on the interior flanging with perforation, having screw to pass perforation screwed hole portion back and on the interior flanging is threaded, it is characterized in that: the perforation on the described lower hem is made up of macropore portion and aperture portion, wherein, aperture portion is positioned at the bottom of macropore portion and is communicated with macropore portion, and the aperture of macropore portion is greater than the aperture of screw head, the aperture of aperture portion is then less than the aperture of screw head, be connected a left side at top cover, under the state on the right plate, described screw passes the aperture portion of perforation.
The side plate of general configuration file cabinet is all thinner, so it is unpractiaca directly opening screwed hole on the interior flanging of side plate, generally can on interior flanging, have a circular mounting hole, again in installing hole with a tubular rivet that is threaded the hole on the riveting gun rivet clasp, to increase the degree of depth of screwed hole portion, guarantee that being threaded of screw is firm.Certainly also the welding of the interior flanging back side fix one with circular mounting hole corresponding nut.
The edge, front and back of above-mentioned top cover all has the kink that bends inwards downwards.The kink at edge has the effect that can increase top cover intensity before and after the top cover, has after top cover is installed on the file cabinet again, and the kink of the rear edge of top cover is shelved on the upper surface of backboard, strengthens the fixing that top cover is installed.
Compared with prior art, advantage of the present utility model is: the perforation on the lower hem is made up of macropore portion and aperture portion, wherein, aperture portion is positioned at the bottom of macropore portion and is communicated with macropore portion, and the aperture of macropore portion is greater than the aperture of screw head, the aperture of aperture portion is then less than the aperture of screw head, during installation, screwed hole portion internal thread on the interior flanging of side plate in office connects screwing earlier, at this moment, screw is not tightened fully, then the macropore portion of the lower hem middle punch of top cover respective side is passed the head of screw, aperture portion with perforation is shelved in the bar portion of screw then, one side of top cover is being supported by the bar portion of screw, then the opposite side of top cover is slowly transferred again, the aperture portion of directly passing perforation with screw is connected with screwed hole portion on the interior flanging of another side plate, at this moment, top cover need not second people and helps, also can be maintained at the installation site, need tighten the top that each screw can be installed in top cover file cabinet U-shaped framework for last, the installation process of this whole top cover only needs a people to finish, and is therefore easy for installation.
