Abstract

The utility model relates to an adjustable door frame structure, belonging to a technical field of door window member. The utility model mainly solves the technical problem so that the metal door frame has adjustable width, convenient installation, high precision verticality, and easy adjustment. In order to reach the purpose, the metal door frame is divided into a front door frame and a rear door frame, At least two pairs of matched slot plates which are fastened adjustably by bolts are arranged fixedly between the front and rear left frames, and at least two pairs of matched slot plates which are fastened adjustably by bolts are arranged fixedly between the front and rear right frames. Front and rear door frames are sleeved at wall body of door cavities and then each pair of overlapped slot plate is locked tightly by bolts, location screws are used to determine the verticality of the door frame, and then expansion bolts are used to fasten the entire aluminum alloy door frame on the wall body of door cavities.

Description

The adjustable sash structure of metal door

Technical field

The utility model relates to the component of the doors and windows technical field, the adjustable sash structure of particularly a kind of metal door.

Background technology

Existing metal door all adopts the fixing doorframe of width, and this doorframe assembly width must adapt with the body of wall width.During assembly, uniform multiple spot fixed point between doorframe and body of wall is with drawing quick-fried screw that doorframe is fixed on the body of wall.There is following weak point in this assembly structure:

(1) fix owing to the doorframe width, and thickness of wall body has plurality of specifications and poor dimensional precision, thereby compliance is relatively poor.

(2) can only be in the doorframe front or the back be provided with a decorative cover, if front-back all is provided with decorative cover, then can't assembly.Can install on the decorative cover of another face to add again after the doorframe and install, increase engineering cost.

(3) on-the-spot assembly trouble is regulated difficulty to the verticality of doorframe.

(4) assembly is fixing just relies on several to draw quick-fried screw, because very out-of-flatness of body of wall is twisted and drawn screw firmly impossible consistent, thereby in the fastening process, the doorframe bending that deforms easily, its verticality is relatively poor, cause crack between a door and its frame big and inhomogeneous, influence its attractive in appearance and result of use.

Summary of the invention

The technical problems to be solved in the utility model is a metal door doorframe width-adjustable, and assembly is convenient, and the verticality precision of doorframe is high and adjusting is easy.

The technical solution that the utility model proposed is such: the adjustable sash structure of a kind of metal door, comprise metal door frame, doorframe and back doorframe before described metal door frame is provided with, doorframe is by preceding upper ledge 1 before being somebody's turn to do, preceding left frame 6, preceding right frame 7 respective end right angles connect and compose, this back doorframe is by back upper ledge 2, the left frame 3 in back, right frame 8 respective end right angles, back connect and compose, preceding, the left frame 6 in back, at least it is adjustable and regulate fixing frid to 4 by screw to be fixed with the two pairs of couplings between 3,5, equally, preceding, the right frame 7 in back, it is adjustable and regulate fixing frid to 9 by screw also to be fixed with the two pairs of couplings between 8 at least, 10.Usually, Zui Jia mode is that three positions, upper, middle and lower are equipped with a pair of frid respectively to 4,5 between forward and backward left frame 6,3; Three positions, upper, middle and lower are equipped with a pair of frid respectively to 9,10 between forward and backward right frame 7,8.Above-mentioned frid has dead slot and/or emptying aperture to being to be connected by external frid 4,9 and adjustable frid 5,10 to form on the frid.

Compared with prior art, the utlity model has following beneficial effect:

(1) owing to adopts forward and backward doorframe and the adjustable syndeton of frid, thereby doorframe width-adjustable, its width adjusting scope is 85-300mm, the flexible distance of maximum adjustable is 215mm, can make the third gear adjustable extent: the 1st grade is 85-120mm, the 2nd grade is 120-180mm, and the 3rd grade is 180-300mm, to be fit to the body of wall requirement of different-thickness.

(2) specification is few, standardization level is high, is fit to produce in enormous quantities.

(3) the whole assembly of doorframe and regulate easy, its verticality precision height, crack between a door and its frame is little and even.

(4) because adopting, doorframe divides body structure, so forward and backward doorframe can be provided with upholstery border, this upholstery border has the decoration function of door pocket, both sheltered from the gap of doorframe and body of wall, have the stereo cording decorative effect again, elegant in appearance, therefore, the doorframe of this structure need not refill door pocket, has reduced construction costs.

Description of drawings

Fig. 1 is the structural representation of an embodiment of the utility model, and preceding doorframe and adjustable frid are released state with back doorframe and external frid among the figure.

Fig. 2 is in the structure shown in Figure 1, and forward and backward doorframe has connected into the adjustable sash structure schematic diagram of assembled state.

The specific embodiment

By following embodiment the utility model is further elaborated.

Referring to Fig. 1, shown in Figure 2, the adjustable frid 5 of horizontal arrangement all is housed in top, middle part, the bottom of the preceding left frame 6 of preceding doorframe and preceding right frame 7 lateral surfaces, the one end is packed on the doorframe, remainder is extension backward, this is adjustable, and frid 5 middle parts are provided with a horizontal dead slot 5-1, and the upper and lower part respectively is drilled with the emptying aperture 5-2 that a row of horizontal is arranged.The external frid 4 of horizontal arrangement all is housed in top, middle part, the bottom of right frame 8 lateral surfaces of back left frame 3 and back of back doorframe, the one end is packed on the doorframe, remainder is extension forward, these external frid 4 upper, middle and lower portions are provided with the horizontal dead slot 4-1 that is parallel to each other respectively, match with the dead slot 5-1 and the emptying aperture 5-2 of corresponding adjustable frid 5.During assembly, forward and backward doorframe is entangled by dress door opening body of wall, corresponding adjustable frid 5 overlaps mutually with external frid 4.At first every group of frid locked adjustable frid 5 and external frid 4 with 2 lock-screws 13, guaranteed the width requirement of doorframe.Regulate the verticality of left and right doorframe then with spirit level, meanwhile, each is screwed into 2-4 to frid from its emptying aperture and props up dog screw 12 until touching the door opening body of wall, whole like this aluminium alloys doorframe has been positioned on the very high position of verticality, between every pair of frid middle part and corresponding body of wall, load onto then and draw quick-fried screw 11, whole doorframe with regard to assembly firmly on the door opening body of wall.After this doorframe was loaded onto metal door, the gap between door and the doorframe was not more than 3mm, and doorframe is pushed open in that angle and just rested on this angle position, not positioning automatically.
