[0027] Sliding doors offer advantages such as not taking up interior space, a beautiful appearance, economical price, and good sealing. Using high-grade tracks, they open smoothly with a gentle push. Large panes of glass not only increase indoor lighting but also improve the overall appearance of the building. Hook-and-loop fasteners are commonly used in sliding doors. Currently, hook-and-loop fastener covers on the market are generally installed using a snap-fit ​​method. However, this snap-fit ​​installation method is prone to loosening due to decreased elasticity caused by external impacts or aging, making its installation unstable.

[0028] To solve the above problems, this utility model proposes a door frame hook 10.

[0029] Please see Figures 1 to 3 In one embodiment of this utility model, the door frame hook 10 includes a hook body 100 and a hook component 200. The hook body 100 includes an assembly body 110 and a hook cover 120. The assembly body 110 is provided with an assembly cavity 111 and an opening communicating with the assembly cavity 111. The hook cover 120 has a snap-fit ​​section 121 and a screw section 122 that are bent laterally on opposite sides. The snap-fit ​​section 121 snaps into the assembly body 110, and the screw section 122 is screwed into the assembly body 110. The end of the assembly body 110 away from the hook cover 120 is provided with a mounting groove 130 for installing glass 20. The hook component 200 is provided with a hook body 210 extending toward the mounting groove 130 and is used to cooperate with the hook component 200 of another door frame hook 10.

[0030] The technical solution of this utility model involves providing a laterally bent snap-fit ​​section 121 and a screw-fit section 122 on opposite sides of the hook-and-loop cover 120. The snap-fit ​​section 121 snaps into the assembly body 110, and the screw-fit section 122 is screwed into the assembly body 110. It can be understood that when assembling the end cover, the snap-fit ​​section 121 is first snapped into the assembly body 110, which allows for quick positioning and initial fixation. Then, the screw-fit section 122 is screwed into the assembly body 110. During screw connection, the potential small gaps in the snap-fit ​​can be filled through threaded tightening, allowing the hook-and-loop cover 120 to fit more tightly into the assembly body 110, reducing gaps and improving the sealing performance of the door and window. This prevents rainwater from seeping in or dust from entering the assembly cavity 111, while also reducing wind noise and improving the sound insulation effect of the door and window. Moreover, the screw connection provides a tightening force, preventing displacement of the snap-fit ​​section 121 while locking the screw-fit section 122, enhancing the overall structural stability. Therefore, this solution can improve the installation stability of the hook-and-loop cover 120.

[0031] Optionally, the threaded section 122, the hook and bracket 200, and the assembly body 110 are fastened together by the same screw. This reduces the relative displacement between the threaded section 122, the hook and bracket 200, and the assembly body 110, preventing loosening or abnormal noise caused by vibration or external forces. The preload of the screw can act simultaneously on the threaded section 122, the hook and bracket 200, and the assembly body 110, distributing the stress points, reducing the risk of stress concentration at a single connection, and improving the overall fatigue resistance of the hook and bracket. Traditional designs may require multiple screws to fix each component separately, while this design only requires one screw to fix the threaded section 122, the hook and bracket 200, and the assembly body 110, simplifying the installation steps and shortening construction time. Using a single screw as a reference point ensures the consistency of the relative positions of the three components, avoiding cumulative errors during step-by-step installation. Integrated fixing avoids the small gaps caused by multiple screws, improving the sealing performance of doors and windows; it also makes the appearance simpler, reducing protrusions or seams. Of course, this solution is not limited to this. In other embodiments, the screw section 122 and the assembly body 110 are connected by a screw, while the hook member 200 and the assembly body 110 are connected or snapped together by another screw.

[0032] Furthermore, the screw section 122 is provided with a screw groove 122a, and the screw is screwed into the bottom of the screw groove 122a, the hook member 200 and the assembly body 110 in sequence; specifically, the screw groove 122a can prevent the head of the screw from being exposed on the surface of the screw section 122, thereby increasing the aesthetics.

[0033] Furthermore, the hook-and-groove component 200 has a recess, and the threaded section 122 is placed in the recess. The screw is screwed into the bottom of the screw groove 122a, the hook-and-groove component 200, and the assembly body 110 in sequence, which can prevent the threaded section 122 from protruding from the hook-and-groove component 200. Furthermore, the side of the threaded section 122 facing away from the assembly cavity 111 is flush with the side of the hook-and-groove component 200 facing away from the assembly cavity 111.

[0034] Furthermore, the door frame hook 10 also includes a weatherstripping 300, which is fitted into the screw groove 122a. It can be understood that when the sliding door 1 is closed, the weatherstripping 300 ensures the sealing between the hook components 200, greatly improving the windproof and waterproof performance of the door frame hook 10. Moreover, by installing the weatherstripping 300 into the screw groove 122a, this design can also cover the screws, making the structure of the door frame hook 10 more compact and aesthetically pleasing.

[0035] Optionally, the hook and bracket 200 can be snapped into the assembly body 110. This installation method is simple, easy to install and disassemble, and can improve the installation and disassembly efficiency of the hook and bracket 200.

[0036] Reference Figure 3 Furthermore, in this embodiment, the hook-and-go piece 200 is snapped onto the assembly body 110, and the hook-and-go piece 200, the screw connection section 122, and the assembly body 110 are fastened together by the same screw. It can be understood that during assembly, the hook-and-go piece 200 is first snapped onto the assembly body 110 to achieve quick positioning and initial fixation of the hook-and-go piece 200. Then, the hook-and-go piece 200, the screw connection section 122, and the assembly body 110 are fastened together by screws to enhance the stability of the hook-and-go piece 200.

[0037] Optionally, the assembly body 110 is provided with a first engaging portion 112, which includes a first segment 112a and a second segment 112b that are bent and connected to each other. The first segment 112a is connected to the assembly body 110 to form a first engaging groove between the second segment 112b and the assembly body 110. The hook and bracket 200 is provided with a second engaging portion 220, which includes a third segment 221 and a fourth segment 222 that are bent and connected to each other. The third segment 221 is connected to the hook and bracket 200 to form a second engaging groove between the fourth segment 222 and the hook and bracket 200. The fourth segment 222 engages in the first engaging groove, and the second segment 112b engages in the second engaging groove. This engaging structure is stable and helps to improve the installation stability of the hook and bracket 200. Of course, this solution is not limited to this. In other embodiments, a recessed engaging groove can be provided on the assembly body 110, and the hook member 200 can be provided with an engaging protrusion corresponding to the engaging groove, and the engaging protrusion engages in the engaging groove.

[0038] Furthermore, the hook and pin 200 is also provided with a sealing section 230 extending toward the assembly cavity 111. The sealing section 230 abuts between the end faces of the hook and pin cover 120 and the assembly body 110. This can increase the contact area between the hook and pin 200, the hook and pin cover 120 and the assembly body 110, thereby increasing the sealing of the screw installation position and improving the sealing of the assembly cavity 111.

[0039] Optionally, in this embodiment, the engaging portion 113 that engages with the engaging segment 121 is located on the inner wall of the assembly cavity 111. This allows the engaging segment 121 to be hidden within the assembly cavity 111 during engagement, thereby enhancing the aesthetics of the door frame hook 10. Of course, this solution is not limited to this. In other embodiments, a recess may be provided on the outer side of the assembly body 110 corresponding to the engaging segment 121, and the engaging portion 113 that engages with the engaging segment 121 may be located within the recess. After the engaging segment 121 and the engaging portion 113 are engaged, the side of the engaging segment 121 facing away from the engaging portion 113 is flush with the side of the assembly body 110 with the recess.

[0040] Optionally, the assembly body 110 has a mating part 113 corresponding to the snap-fit ​​section 121. The free end of the mating part 113 is flush with the end face of the hook cover 120. This can improve the aesthetics of the door frame hook 10 and also avoid increasing the width of the door frame hook 10.

[0041] Furthermore, the hook and bracket component 200 is made of nylon. This utilizes the material's heat resistance, wear resistance, and mechanical strength to improve the airtightness between the two mating hook and bracket components 200. Moreover, nylon also has good thermal insulation properties, effectively isolating heat between the two mating hook and bracket components 200. Of course, this solution is not limited to this; in other embodiments, the hook and bracket component 200 can also be made of polyoxymethylene (POM) or aluminum alloy.

[0042] Reference Figure 1 and Figure 2Optionally, the hook member 200 is further provided with a hook elastic member, which is disposed close to the hook body 210 to form a sealed space between the hook body 210 and the hook elastic member. Specifically, the sliding door 1 includes a first sliding door 1 and a second sliding door 1. The door frame hook 10 on the first sliding door 1 is referred to as the first door frame hook 10, and the door frame hook 10 on the second sliding door 1 is referred to as the second door frame hook 10. When the sliding door 1 is in the closed state, the structure of the hook member 200 of the first door frame hook 10 is inserted into the sealed space of the hook member 200 of the second door frame hook 10 and abuts against the hook elastic member on the hook member 200 of the second door frame hook 10. It can be understood that at this time, the structure of the hook member 200 of the second door frame hook 10 is also inserted into the sealed space of the hook member 200 of the first door frame hook 10 and abuts against the hook elastic member on the hook member 200 of the first door frame hook 10; thereby playing a role in sound insulation and preventing air convection.

[0043] Furthermore, the hook elastic element is made of heat-insulating elastic material, such as but not limited to silicone, nylon, etc. Since the two sliding doors 1 are in contact with each other through the hook body 210 of one hook element 200 and the hook elastic element of the other hook element 200, instead of directly using the hook bodies 210 of the two hook elements 200 to contact each other, a sealing effect can be achieved while also providing heat insulation.

[0044] Furthermore, the hook-and-loop elastic element is snapped onto the hook-and-loop component 200. This installation method is simple and can improve installation and assembly efficiency. Even after long-term use, when the elasticity of the hook-and-loop elastic element weakens or is damaged, it is convenient for the user to replace it themselves. Of course, this solution is not limited to this. In other embodiments, the hook-and-loop elastic element can also be glued onto the hook-and-loop component 200.

[0045] Optionally, the assembly body 110 has a first pressure member and a second pressure member at the end away from the hook cover 120, forming a mounting groove 130 between the first pressure member and the second pressure member for mounting the glass 20. The first pressure member is engaged on the assembly body 110, and the formed mounting groove 130 facilitates the installation of the glass 20. Of course, this solution is not limited to this. In other embodiments, the assembly body 110 has a first pressure member and a second pressure member spaced apart at the end away from the hook cover 120, and the mounting groove 130 is formed between the first pressure member and the second pressure member, while the first pressure member and the second pressure member are respectively welded to the first cavity wall.

[0046] Furthermore, the first pressure wire member is provided with a first locking part and a second locking part at intervals along the arrangement direction of the first pressure wire member and the second pressure wire member. The first cavity wall is provided with a first locking engagement part 113 and a second locking engagement part 113 respectively corresponding to the first locking part and the second locking part. Such a locking structure is more stable, thereby reducing the probability of the first pressure wire member shaking.

[0047] Furthermore, the second snap-fit ​​part is fitted with a round rubber strip that contacts the second snap-fit ​​mating part 113, which provides a good sealing effect, a cushioning effect, and high reliability. The second snap-fit ​​part has a side-opening round groove, and the round rubber strip is fitted into the side-opening round groove.

[0048] Optionally, the first pressure member is provided with a weight reduction cavity. That is, the first pressure member is similar to a square tube, and the cavity inside the square tube is the weight reduction cavity. Such a first pressure member has strong bending and torsional resistance, which is conducive to improving the strength of the first pressure member while reducing the weight of the first pressure member, thereby reducing the weight of the hook structure.

[0049] This utility model also proposes a sliding door 1, which includes a door frame hook 10. The specific structure of the door frame hook 10 is as described in the above embodiments. Since this sliding door 1 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0050] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
