Description

Technical Field

[0001] The utility model relates to the field of door accessories, in particular to a door knock-down hook used for a heavy door. Background Art

[0002] A door is a device that separates private space from public space, making people's living space more private. With the continuous advancement of industrial and technological modernization, people's living standards are constantly improving, and people's requirements for doors are getting higher and higher. With the development of science and technology, household door devices have developed to a great extent, and their types and quantities are also increasing day by day. Heavy doors are becoming more and more popular in people's lives.

[0003] A door stopper is a device connected to a door that is installed on a wall or floor to effectively prevent the door from colliding with other objects. It can also be called a door stopper. The functions of the two are the same, both of which limit the movement of the door connected to the door stopper. Usually, a door stopper relies on the magnetic attraction of a magnet to fix the door after it is opened. However, for heavy doors, since the force of this door stopper can only withstand lighter wooden doors, the door stopper is prone to deformation and damage after long-term use, which makes it easy to make noise when opening and closing the door, which is not conducive to use. In addition, the door is prone to hitting the wall after the door stopper is damaged. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a door knock-down hook which is not easy to deform and is used for heavy doors.

[0005] The utility model is achieved in this way:

[0006] A door knock-down hook for heavy doors comprises a first base fixed behind the door and a second base fixed on the wall, wherein the first base is concentric with the second base; a fixing plate is vertically connected to the first base, and a through hole is provided on the fixing plate; a secondary pipe and a main pipe are connected to the second base in sequence, and a hook assembly elastically hooked to the through hole is connected to the main pipe; an anti-collision protective sleeve is provided on the end of the main pipe.

[0007] Furthermore, the hook assembly includes a hook support frame fixed on both sides of the main pipe, the hook support frame is provided with an axle pin connecting the two ends, and the axle pin is sequentially sleeved with a torsion spring and a hook from the inside to the outside, so that the hook head of the hook is elastically hooked to the through hole.

[0008] Furthermore, a handheld clamp is provided at the other end of the hook.

[0009] Furthermore, the through hole is a square through hole.

[0010] Furthermore, the anti-collision protective cover is anti-collision silicone.

[0011] Furthermore, a chemical anchor bolt or expansion bolt threadedly connected to the main pipe is sleeved inside the secondary pipe; the anchor bolt or expansion bolt passes through the second base and is fixed to the wall.

[0012] Furthermore, the anchor bolt or expansion bolt is threadedly connected to the second base.

[0013] Furthermore, the main pipe is fixed to the anchor bolt or expansion bolt by means of a jackscrew.

[0014] The advantages of the utility model are that the door-colliding hook of the utility model is used for being installed on a heavy door, is stable and firm, is not easy to be deformed and damaged, and can prevent the door from colliding with the wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of the utility model is as follows:

[0022] See also Figure 1 and Figure 2 As shown, the utility model is a door knocking hook for heavy doors, comprising a first base 1 fixed behind the door, and a second base 2 fixed on the wall, the first base 1 and the second base 2 are concentric; a fixing plate 3 is vertically connected to the first base 1, and a through hole 31 is provided on the fixing plate 3; a secondary pipe 4 and a main pipe 5 are connected to the second base 2 in sequence, and a hook assembly 6 elastically hooked to the through hole 31 is connected to the main pipe 5; an anti-collision protective cover 7 is provided on the end of the main pipe 5.

[0023] In a specific embodiment, the first base 1 and the second base 2 are both brass bases of a certain thickness.

[0024] The hook assembly 6 includes a hook support frame 61 fixed to both sides of the main pipe 5, and the hook support frame 61 is provided with an axle pin 62 connecting the two ends, and the axle pin 62 is sequentially sleeved with a torsion spring 63 and a hook 64 from the inside to the outside, so that the hook head 641 of the hook 64 can be elastically hooked to the through hole 31. The other end of the hook 64 is provided with a hand-held clamp block 642.

[0025] In a specific embodiment, the shaft pin 62 is a threaded screw, the hand-held clamp block 642 is a square brass block, which is convenient for manual clamping, and the hook head 641 is arranged in an arc shape to facilitate the rebound of the hook 64.

[0026] In a specific embodiment, the through hole is a square through hole.

[0027] In a specific embodiment, the anti-collision protective cover 7 is anti-collision silicone.

[0028] In a specific embodiment, the main pipe 5 is a brass threaded pipe, and the auxiliary pipe 4 is a brass pipe; the auxiliary pipe 4 is provided with a chemical anchor bolt 8 threadedly connected to the main pipe 5 to facilitate the disassembly of the brass pipe; the other end of the chemical anchor bolt 8 is threadedly connected to the second base 2 and fixed to the wall to facilitate the disassembly of the base.

[0029] In a specific embodiment, the main pipe 5 is provided with a through hole at the position where it is connected to the chemical anchor 8, and the top screw 9 passes through the through hole to the chemical anchor 8, so that the main pipe 5 is fixed at a specific position.

[0030] The specific installation is as follows:

[0031] (1) Positioning on the wall and behind the door respectively to ensure that the first brass base 1 and the second brass base 2 are concentric;

[0032] (2) drilling holes in the wall and fixing chemical anchor bolts 8;

[0033] (3) Screw in the second brass base 2;

[0034] (4) Calculate and cut the brass tube according to the distance from the door to the wall;

[0035] (5) Fix the hook support frame 61 to the main pipe 5 with bolts, fix the hook 64 and the torsion spring 62 in the middle of the hook support frame 61 with the sub-screws 62, and cover the anti-collision silica gel 7 on the head of the main pipe 5;

[0036] (6) Screw the main pipe 5 into the chemical anchor bolt 8, determine the position, ensure that the hook faces downward, and screw in the top screw 9 to fix it;

[0037] (7) Fix the first brass base 1 to the door leaf with three bolts.

[0038] The specific usage is as follows:
