Description
Technical Field
The utility model relates to a prevent fire door frame technical field, specifically be a prevent fire door frame with solderless fastening structure.
Background
The fire door preparation is all adopted galvanized sheet to process the preparation traditionally, in order to satisfy customer's demand, just need be equipped with the paint spraying line like this, obviously, can serious polluted air environment, prevents fire door preparation and adopts color-coated sheet processing preparation, need not be equipped with the paint spraying line, does not pollute, but just has a problem, if prevents that fire door frame adopts welding technique to connect, and the welding back, the door frame junction can certainly turn black. Seriously affecting the beauty of the product, and in order to solve the problems, provides a fireproof door frame with a welding-point-free fastening structure.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prevent fire door frame with no solder joint fastening structure to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a prevent fire door frame with no welding point fastening structure, includes horizontal door frame, lateral wall is laminated vertical door frame respectively about horizontal door frame, first connecting hole is seted up to horizontal door frame left side wall, the second connecting hole is seted up to vertical door frame left side wall, the lead screw is pegged graft respectively to first connecting hole inner wall and second connecting hole inner wall, lead screw lateral wall spiro union nut, the antiskid ring is fixed in nut lateral wall and the centre gripping of vertical door frame lateral wall.
Preferably, the side walls of the front end and the rear end of the longitudinal door frame are respectively fixedly connected with the clamping plates.
Preferably, a corner is arranged in the middle of the longitudinal door frame side wall.
Preferably, the transverse door frame is provided with two first connecting holes, and the longitudinal door frame is provided with four second connecting holes.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a prevent fire door frame with no solder joint fastening structure, the lead screw has, the nut structure, can splice two vertical door frames and horizontal door frame fixedly, the operation of welding process has been removed from, it is more level and more smooth and the outward appearance of blackening with the outward appearance to make the outward appearance of whole face more pleasing to the eye simultaneously, the painted degree of difficulty of later stage door body fitment has also been reduced, realized not having the solder joint to prevent fire door frame and fixed, the welding operation who removes from, make the door frame surface level and more smooth and the unified purpose of colour.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a partially cut-away rear view of the present invention;
fig. 3 is an enlarged view of a portion a in fig. 1.
In the figure: the structure comprises a transverse door frame 1, a first connecting hole 101, a longitudinal door frame 2, a second connecting hole 201, a lead screw 3, a nut 4, an anti-slip ring 5, a clamping plate 6 and a corner 7.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a prevent fire door frame with solderless fastening structure, including horizontal door frame 1, lateral wall is the vertical door frame 2 of laminating respectively about horizontal door frame 1, first connecting hole 101 is seted up to 1 left side wall of horizontal door frame, second connecting hole 201 is seted up to 2 left side walls of vertical door frame, lead screw 3 is pegged graft respectively to first connecting hole 101 inner wall and second connecting hole 201 inner wall, 3 lateral wall spiro union nuts 4 of lead screw, the fixed antiskid ring 5 of nut 4 lateral wall and 2 lateral wall centre gripping of vertical door frame, vertical door frame can adopt when the installation with the mode fixed connection of wall body gap department watering cement, adopt dull and stereotyped class instrument to level and smooth the processing behind the people, the design of this device door frame also can be used.
Particularly, both ends lateral wall is fixed connection splint 6 respectively around vertical door frame 2, and vertical door frame is more firm to grabbing of wall body when the interpolation through splint, strengthens the impact of rocking to horizontal.
Particularly, the corner 7 is arranged in the middle of the side wall of the longitudinal door frame 2, the bending strength of the door frame in the general direction can be enhanced by additionally arranging the corner, and the structure is more stable in an earthquake.
Particularly, two first connecting holes 101 have been seted up to horizontal door frame 1, and four second connecting holes 201 have been seted up to vertical door frame 2, make the fixed mounting of horizontal door frame to vertical door frame more firm through two first connecting holes.
The working principle is as follows: when the utility model discloses when using, this device passes through the grafting of screw rod to first connecting hole and second connecting hole, makes the concatenation of vertical door frame and horizontal door frame, then makes the screw rod prevent to move from through the nut, has removed welding process's loaded down with trivial details from, makes the structure of device leak the junction more level and more smooth and pleasing to the eye, and the content of not doing detailed description in this specification belongs to the prior art that technical personnel are publicly known in the field.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
