Description

Technical Field

[0001] The utility model relates to the technical field of installation of set doors, in particular to a special installation fastener for set doors with two-way hooks. Background Art

[0002] There are many ways to install set doors, but basically they all use composite boards as the base and then use pneumatic nails to fix the door frames and lines: when using nails to fix the door frames, if the door frames, especially the top plate cross-head frames, are relatively short and slightly bent, it will be more troublesome for the installer to correct them. Moreover, the base composite board is directly fixed on the wall and is more susceptible to moisture. Once it is damp, it is easy to deform, soften, or even fall off. This is also one of the disadvantages of this installation method.

[0003] At present, 90% of the door sets have bayonet lines. Affected by the humidity in each place, the slots on both sides of the door sets will shrink or widen to varying degrees. When the slots shrink, the installer can only use tools to pry the slots wider, which is not only slow but also easy to pry the slots too wide, resulting in gaps and loose clamping when clamping the lines; when the slots themselves become wider, there will also be gaps and loose clamping when clamping the lines. In this case, the lines can only be reinforced in the slots with nails. Because wood has the characteristics of swelling and shrinking when wet, in order to install it firmly, the installer will generally use nails to fix the lines, which will leave nail holes and gaps on the surface of the junction of the slots and the lines, affecting the overall appearance of the door sets. Is there a special installation fastener for door sets with a built-in two-way hook that can solve the above problems? It is urgent to study and has become a problem that needs to be solved in the entire wooden door installation field. Utility Model Content

[0029] The following will be combined Figure 1-7 , a special installation fastener for a set door with a built-in two-way hook involved in the embodiment of the present application is described in detail. It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation on the present application.

[0030] like Figure 1-7 As shown, a special installation fastener 100 for a set door with a built-in two-way hook includes: a base 200, a fastener 100, and several bases 200 are installed on the wall; several fasteners 100 are installed on the base 200 in a one-to-one correspondence, and are used to fix the door frame. The fastener 100 includes an a plane 3, a b plane 4 at the head part of the fastener 100, a c plane 5 at the middle part, and a d plane 6 and an e plane at the tail part of the fastener 100, and the e plane is fixedly connected to the c plane 5. A first connecting hole 11 is provided on the d plane 6. An installation avoidance hole 10 is provided on the c plane 5, and the installation avoidance hole 10 is used for installing a screwdriver connecting the fastener 100 and the base 200 and providing space for the screwdriver when turning the knob screw. The base 200 is provided with an installation hole 8 for connecting to the wall and a second connecting hole 9 connected to the fastener 100.

[0031] Two groups of oppositely arranged barbs, A and B, are provided on the b plane 4, wherein the group A barbs 1 are arranged close to the a plane 3, the group B barbs 2 are arranged close to the c plane 5, the group A barbs 1 are arranged toward the d plane 6, and the group B barbs 2 are arranged away from the d plane 6, the group A barbs 1 are engaged with the slots of the door frame, and the group B barbs 2 are engaged with the closing edge lines arranged in the slots.

[0032] In some embodiments, the fastener 100 may include a long fastener 100 and a short fastener 100, and both the long fastener 100 and the short fastener 100 are made of stainless steel, which effectively solves the problem that the original composite board base is not moisture-proof. Figure 2 , Figure 3As shown: the shapes of the long and short fasteners 100 are the same, but the lengths of the middle parts of the fasteners 100 are different, which are respectively suitable for the situation that the door frame is thick in the front and thin in the back. The two types of fasteners 100 are composed of two planes a and b at the head part of the fastener 100 and a c plane 5 in the middle part, with an installation avoidance hole 10 in the middle, and two surfaces d and e at the tail part of the fastener 100. The head part of the fastener 100 is connected at 90 degrees by plane a 3 and plane b 4. Plane a 3 is smaller and its width is consistent with the width of the sleeve slot. When the head part of the fastener 100 is inserted into the slot, plane a 3 plays a supporting role at the bottom of the slot; plane b 4 is a rectangular plane. When inserted into the slot, the back of the plane is tightly against the inner wall of one side of the slot. Two groups A and B of four triangular hooks are provided on plane b 4. The hook 1 of group A is on the back of plane b, and its hook tip is oblique to the outer mouth of the slot. The hook 2 of group B is on the front of plane b 4, and its tip is oblique to the bottom of the slot. When we put the head part of the fastener 100 into the door sleeve slot and let the back of plane b 4 be tightly against the inner wall of one side of the slot, plane b The group A barbs 1 on the back of surface 4 also just pierce into the inner wall of one side of the slot, which can effectively prevent the fastener 100 from falling off; at this time, the group B barbs 2 are on the front side of plane b, and the hook tip is obliquely facing the bottom of the slot, as shown in Figure 6. When the closing edge line is inserted into the slot, the barbs B firmly hook the closing edge line, and the group A barbs 1 are also hooked on the slot wall. The slot and the closing edge line are hooked together by two groups of reverse barbs, so that the line can only go in but not out, so there is no need to nail the line on the line to fix it, and there will be no problem of nail holes, and the raised parts of the two groups A and B barbs also push the line to the other side (exposed surface) of the slot, thereby greatly reducing the gap between the line and the exposed surface of the slot.

[0033] like Figure 1 As shown, the base 200 is a structure similar to a channel steel, and a plurality of mounting holes 8 are provided from one end of the channel steel to the middle bottom. During installation, steel nails are used to fix the base 200 to the edges of both sides of the side wall of the door opening through the holes.

[0034] The other end of the channel steel is provided with three second connection holes 9 connected with the fasteners 100. When installing, this end is aligned with the edges of the two sides of the door opening. When installing, the base 200 is fixed on the left and right sides of the door opening and the top wall in proportion. Figure 5 shown.

[0035] After the base 200 is installed, the three assembled panels are placed into the door opening and preliminarily calibrated, and then each fastener 100 is placed and clamped in the slot at the position corresponding to the base 200, and then connected together through the first connection hole 11 at the tail of each fastener 100 and the second connection hole 9 at one end of the base 200 using a self-drilling screw, as shown in FIG. Figure 6shown.

[0036] Then, adjust the tightness of the self-drilling screws to straighten each door frame (including the door frame top plate). Because the screws have strong pulling force, it is very convenient to straighten. While straightening, use a wooden stake to pad the gap between the door frame and the wall. When the door frame slot shrinks and narrows, you can also use the pulling force of the screws to open the slot. This method makes it easier to control the force and does not easily damage the slot.

[0037] Connect all the fasteners 100 and bases 200 fixed in the door frame slots accordingly and make preliminary adjustments. Hang the door leaf with hinges and adjust the gap between the door leaf and the door frame. Then fill the gap between the door frame and the door opening with foam glue. Knock the cut lines into the slots and adjust them. Install the locks and door stops. A complete set of door sets is now installed.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
