Description

Technical Field

[0001] The utility model belongs to the technical field of hardware accessories, and particularly relates to a door frame hanging box. Background Art

[0002] A hanging rail sliding door, also known as a hanging sliding door, is a door that slides supported by an upper hanging wheel. This type of door opens silently, has no threshold, is beautiful, and is widely used as a partition in balconies, restaurants, kitchens, bathrooms, and other places. Hanging rail sliding doors are usually connected to the upper hanging wheel via a hanging box. The connection between the traditional hanging box and the door frame is shown in the Chinese utility model patent with authorization announcement number "CN 209398129 U" and the name "A Door Frame Hanging Box and Door Frame Hanging Box Fixing System." The hanging box is connected to the door frame by inserting self-threading screws into the U-shaped groove at the bottom of the hanging box. The disadvantages are that the self-threading screws are easy to lose and the connection strength is poor. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a door frame hanging box in which the self-powered screws are not easily lost and the connection strength is better.

[0004] In order to solve the above problems, the technical solution adopted by the utility model includes: a hanging box body, and positioning flanges are provided on both sides of the hanging box body, and its characteristics are: the bottom of the hanging box body is provided with an inclined screw hole and a self-tapping screw connected to the screw hole, and the screw hole consists of a closed screw hole and an open screw hole, and the closed screw hole is provided with a screw that engages with the self-tapping screw.

[0005] The door frame hanging box is characterized in that the inclination angle of the screw hole is 5°-10°.

[0006] The door frame hanging box is characterized in that a group of first grooves arranged at intervals are provided on the inner wall of the open screw hole.

[0007] The door frame hanging box is characterized in that the surface of the positioning flange is provided with a corrugated surface.

[0008] The door frame hanging box is characterized in that a positioning baffle is provided at the end of the hanging box body corresponding to the position of the screw hole.

[0009] The door frame hanging box is characterized in that second grooves are provided on both sides of the hanging box body corresponding to the open screw hole.

[0010] The door frame hanging box is characterized in that an annular positioning groove is provided on the screw head of the self-tapping screw, and a convex point that cooperates with the annular positioning groove is provided in the closed screw hole.

[0011] The advantages of the door frame hanging box of this invention are: the screw holes are composed of closed screw holes and open screw holes, and by arranging threads that engage with self-tapping screws and positioning convex points in the closed screw holes, the tapping screws are not easy to fall off and the connection is more stable and reliable.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is an exploded view of the door frame hanging box of the utility model;

[0014] Figure 2 It is a cross-sectional view of the door frame hanging box of the utility model;

[0015] Figure 3 It is a schematic diagram of the installation of the door frame hanging box of the utility model. DETAILED DESCRIPTION

[0016] like Figures 1 to 3 As shown, the door frame hanging box of the present invention includes a hanging box body 1, and positioning flanges 2 are provided on both sides of the hanging box body 1. The positioning flanges 2 are positioned and matched with the steps in the door frame 15. The bottom of the hanging box body 1 is provided with an inclined screw hole 3 and a self-tapping screw 4 connected to the screw hole 3. The screw hole 3 is composed of a closed screw hole 5 and an open screw hole 6. The closed screw hole 5 is provided with a thread 7 that engages with the self-tapping screw 4. During assembly, the door frame hanging box is installed from the side of the door frame, and then the self-tapping screw 4 is tightened. When the self-tapping screw 4 is screwed to a certain extent, the thread on the top will extend out of the open screw hole 6 and contact the inner wall of the door frame, so that the door frame hanging box can be tightened.

[0017] Preferably, the inclination angle of the screw hole 3 is 5°-10°, and the most ideal is 6°. When the self-tapping screw 4 is screwed into place, it can achieve the best fastening state with the door frame.

[0018] Preferably, a group of spaced first grooves 8 are provided on the inner wall of the open screw hole 6. By providing the first grooves 8, the self-tapping screw 4 can be more easily embedded in the open screw hole 6 during the tightening process, thereby being tightened more tightly.

[0019] Preferably, the surface of the positioning flange 2 is provided with a corrugated surface 9 to prevent slipping, thereby improving the stability of the door frame hanging box connection.

[0020] Preferably, a positioning baffle 10 is provided at the end of the hanging box body 1 corresponding to the position of the screw hole 3. It is used to position the hanging box body 1 after it is inserted into place to facilitate installation.

[0021] Preferably, the hanging box body 1 is provided with second grooves 11 on both sides corresponding to the open screw hole 6. By providing the second grooves 11, the open screw hole 6 has a certain tension, thereby making it easier for the self-tapping screw 4 to be inserted into the open screw hole 6 during the tightening process, thereby being able to tighten more tightly.

[0022] Preferably, an annular positioning groove 13 is provided on the screw head 12 of the self-tapping screw 4, and a protrusion 14 is provided in the closed screw hole 5 to cooperate with the annular positioning groove 13. When the self-tapping screw 4 is tightened, the protrusion 14 is locked into the annular positioning groove 13 to prevent the self-tapping screw 4 from falling off due to loosening.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
