Description

Technical Field

[0001] This utility model relates to the field of sliding door technology, and in particular to a heat-insulating hook and a sliding door. Background Technology

[0002] Insulating hinges are commonly used in sliding doors. To ensure proper insulation, the heat retention of the hinges is crucial. For example, in cold winters, the indoor temperature is higher than the outdoor temperature. Therefore, heat can easily be transferred quickly from the indoors to the outside through the insulating hinges, causing a sharp drop in indoor temperature and discomfort for residents. However, existing sliding door hinges have poor insulation performance during use. Utility Model Content

[0003] The main purpose of this utility model is to propose a heat-insulating hook and sliding door, which aims to improve the heat insulation effect of the hook.

[0004] To achieve the above objectives, the present invention provides a heat-insulating hook, comprising:

[0005] The hook-and-eye body has adjacent first and second sidewalls. A first pressure line member and a second pressure line member are spaced apart on the first sidewalls to form a mounting groove between the first and second pressure line members. The mounting groove is used for glass mounting. The second pressure line member is disposed close to the second sidewall and is connected to the hook-and-eye body via a thermally insulating connector.

[0006] The hook and bracket are disposed on the second side wall. The hook and bracket are provided with a hook body extending toward the mounting groove. The hook body is used to cooperate with the hook and bracket of another heat-insulating hook and bracket.

[0007] In one embodiment, the first sidewall and the second pressure wire member are each provided with a slot, and the two ends of the heat-insulating connector are respectively engaged in the two slots.

[0008] In one embodiment, the slot includes a limiting section and a locking section that are connected to each other. The limiting section is disposed close to the heat-insulating connector, and the width of the limiting section is smaller than the width of the locking section.

[0009] In one embodiment, the heat-insulating connector is formed between the second pressure line member and the hook body by injection molding.

[0010] In one embodiment, the thermal break connector is made of PU, EPS, XPS, or PE.

[0011] In one embodiment, the first pressure wire member is provided with a weight reduction cavity.

[0012] In one embodiment, the first pressure member engages with the hook body.

[0013] In one embodiment, the second sidewall is provided with a first engaging portion, which includes a first segment and a second segment that are bent and connected to each other. The first segment is connected to the second sidewall, and a first engaging groove is formed between the second segment and the second sidewall. The hook and pin are provided with a second engaging portion, which includes a third segment and a fourth segment that are bent and connected to each other. The third segment is connected to the hook and pin to form a first engaging groove between the fourth segment and the hook and pin. The fourth segment engages in the first engaging groove, and the second segment engages in the second engaging groove.

[0014] In one embodiment, the hook body is provided with a reinforcing cavity, and a reinforcing member is provided inside the reinforcing cavity. The first sidewall and the second sidewall are respectively formed on the adjacent sidewalls of the reinforcing cavity.

[0015] This utility model also proposes a sliding door, including the aforementioned heat-insulating hook.

[0016] The technical solution of this utility model connects the second pressure wire component to the hook body through a heat-insulating connector. This heat-insulating connector can isolate the heat between the second pressure wire component and the hook body, which can effectively prevent heat conduction between the hook body and the second pressure wire component. This prevents indoor heat from being transferred to the second pressure wire component through the hook body and then to the outside, thereby reducing indoor cooling and heating costs.

[0027] Insulating hinges are commonly used in sliding doors. To ensure proper insulation, the heat retention of the hinges is crucial. For example, in cold winters, the indoor temperature is higher than the outdoor temperature. Therefore, heat can easily be transferred quickly from the indoors to the outside through the insulating hinges, causing a sharp drop in indoor temperature and discomfort for residents. However, existing sliding door hinges have poor insulation performance during use.

[0028] To solve the above problems, this utility model proposes a heat-insulating hook 10.

[0029] Please see Figures 1 to 3 In one embodiment of the present invention, the heat-insulating hook 10 includes a hook body 100 and a hook component 400. The hook body 100 has adjacent first sidewalls 110 and second sidewalls 120. The first sidewalls 110 are provided with a first pressure line member 210 and a second pressure line member 220 at intervals to form an installation groove 130 between the first pressure line member 210 and the second pressure line member 220. The installation groove 130 is used for mounting glass 20. The second pressure line member 220 is disposed close to the second sidewall 120 and is connected to the hook body 100 through a heat-insulating connector 300. The hook component 400 is disposed on the second sidewall 120 and has a hook body 410 extending toward the installation groove 130. The hook body 410 is used to cooperate with the hook component 400 of another heat-insulating hook 10.

[0030] The technical solution of this utility model connects the second pressure wire component 220 to the hook body 100 through a heat-insulating connector 300. In this way, the heat-insulating connector 300 can isolate the heat between the second pressure wire component 220 and the hook body 100, which can effectively prevent heat conduction between the hook body 100 and the second pressure wire component 220. This prevents indoor heat from being transferred to the second pressure wire component 220 through the hook body 100 and then to the outside, thereby reducing indoor cooling and heating costs.

[0031] Reference Figure 1The second pressure line member 220 is disposed on the side near the hook member 400, that is, the second pressure line member 220 is disposed near another heat-insulating hook member 10. Specifically, the sliding door 1 includes a first sliding door and a second sliding door. The heat-insulating hook member 10 on the first sliding door is referred to as the first heat-insulating hook member 10, and the heat-insulating hook member 10 on the second sliding door is referred to as the second heat-insulating hook member 10. The glass 20 is heat-insulating glass 20, such as, but not limited to, double-layer heat-insulating glass 20. The glass 20 on the first sliding door is referred to as the first glass 20, and the glass 20 on the first sliding door is referred to as the second glass 20. When the sliding door 1 is in the closed state, the inner side of the first glass 20, the hook body 100 of the first heat-insulating hook member 10, the second pressure line member 220 of the second heat-insulating hook member 10, and the inner side of the second glass 20 constitute an inner heat-insulating wall that blocks indoor heat. The outer side of the first glass 20, the first heat-insulating hook member 100, the second pressure line member 220 of the second heat-insulating hook member 10, and the inner side of the second glass 20 constitute an inner heat-insulating wall that blocks indoor heat. The second pressure line component 220 of the hook 10, the hook body 100 of the second heat-insulating hook 10, and the outer side of the second glass 20 constitute an external heat insulation wall that blocks outdoor heat. Since the hook body 100 of the first heat-insulating hook 10 and the second pressure line component 220 of the first heat-insulating hook 10 are connected by a heat-breaking connector 300, and the hook body 100 of the second heat-insulating hook 10 and the second pressure line component 220 of the second heat-insulating hook 10 are also connected by a heat-breaking connector 300, the heat transmission path from the second pressure line component 220 of the first heat-insulating hook 10 to the hook body 100 of the first heat-insulating hook 10 is blocked, thus preventing heat conduction between the inner and outer heat insulation walls, thereby improving the heat insulation effect of the heat-insulating hook 10.

[0032] In one of the heat-insulating hooks 10, the hook body 410 of the hook member 400 is used to cooperate with the hook member 400 of the other heat-insulating hook 10, so as to prevent air convection.

[0033] Reference Figure 3Optionally, the hook member 400 is further provided with a hook elastic member 420, which is disposed close to the hook body 410 to form a sealed space between the hook body 410 and the hook elastic member 420. Specifically, the sliding door 1 includes a first sliding door and a second sliding door. The heat-insulating hook 10 on the first sliding door is referred to as the first heat-insulating hook 10, and the heat-insulating hook 10 on the second sliding door is referred to as the second heat-insulating hook 10. When the sliding door 1 is in the closed state, the structure of the hook member 400 of the first heat-insulating hook 10 is inserted into the sealed space of the hook member 400 of the second heat-insulating hook 10 and abuts against the hook elastic member 420 on the hook member 400 of the second heat-insulating hook 10. It can be understood that at this time, the structure of the hook member 400 of the second heat-insulating hook 10 is also inserted into the sealed space of the hook member 400 of the first heat-insulating hook 10 and abuts against the hook elastic member 420 on the hook member 400 of the first heat-insulating hook 10; thereby playing a role in sound insulation and preventing air convection.

[0034] Furthermore, the hook elastic element 420 is made of heat-insulating elastic material, such as, but not limited to, silicone, nylon, etc. Since the two sliding doors are in contact with each other through the hook body 410 of one hook element 400 and the hook elastic element 420 of the other hook element 400, instead of directly using the hook bodies 410 of the two hook elements 400 to contact each other, it can achieve a sealing effect while also providing heat insulation.

[0035] Furthermore, the hook-and-loop elastic element 420 is snapped onto the hook-and-loop component 400. 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 420 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 420 can also be glued onto the hook-and-loop component 400.

[0036] Optionally, the hook and bracket 400 can be snapped into the second sidewall 120. This installation method is simple and can improve the installation and assembly efficiency of the hook and bracket 400. Of course, this solution is not limited to this. In other embodiments, the hook and bracket 400 can also be welded, bonded or screwed into the second sidewall 120.

[0037] Furthermore, the second sidewall 120 is provided with a first engaging portion 111, which includes a first segment 111a and a second segment 111b that are bent and connected to each other. The first segment 111a is connected to the second sidewall 120, and a first engaging groove is formed between the second segment 111b and the second sidewall 120. The hook and bracket 400 is provided with a second engaging portion 430, which includes a third segment 431 and a fourth segment 432 that are bent and connected to each other. The third segment 431 is connected to the hook and bracket 400 to form a first engaging groove between the fourth segment 432 and the hook and bracket 400. The fourth segment 432 engages in the first engaging groove, and the second segment 111b engages in the second engaging groove. This engaging structure provides better installation stability. Of course, this solution is not limited to this. In other embodiments, a recessed engaging groove can also be provided on the second sidewall 120, and the hook and bracket 400 can be provided with engaging protrusions corresponding to the engaging groove.

[0038] Furthermore, the second sidewall 120 is provided with a plurality of first engaging portions 111 at intervals, and the hook and bracket 400 is provided with a second engaging portion 430 corresponding to each first engaging portion 111, which can improve the installation stability of the hook and bracket 400.

[0039] Optionally, the first sidewall 110 and the second pressure member 220 are each provided with a slot 500, and the two ends of the thermal break connector 300 are respectively engaged in the two slots 500; this installation method is simple and can improve installation and assembly efficiency. Of course, this solution is not limited to this. In other embodiments, the thermal break connector 300 can also be directly bonded between the first sidewall 110 and the second pressure member 220.

[0040] Furthermore, the slot 500 includes a limiting section 510 and a locking section 520 that are connected to each other. The limiting section 510 is located close to the thermal break connector 300, and the width of the limiting section 510 is smaller than the width of the locking section 520. It can be understood that the limiting section 510 can restrict the position of the thermal break connector 300, thereby improving the stability of the installation of the thermal break connector 300.

[0041] Optionally, the thermal break connector 300 is formed between the second pressure line member 220 and the hook body 100 by injection molding. That is, the thermal break connector 300 is directly formed between the second pressure line member 220 and the hook body 100 using injection molding. This allows for a tight bond between the second pressure line member 220 and the thermal break connector 300, as well as between the thermal break connectors 300 themselves, forming a molecular-level bond. This improves the connection stability of the thermal break connector 300. Moreover, directly forming the thermal break connector 300 between the second pressure line member 220 and the hook body 100 using injection molding can eliminate the need for connection steps between the second pressure line member 220 and the thermal break connector 300, as well as connection steps between the thermal break connectors 300 themselves.

[0042] Furthermore, in this embodiment, the first sidewall 110 and the second pressure member 220 are respectively provided with a slot 500. The heat-insulating connector 300 is formed by injection molding between the slot 500 of the first sidewall 110 and the slot 500 of the second pressure member 220, which can further improve the connection stability of the heat-insulating connector 300.

[0043] Optionally, the thermal break connector 300 is made of PU (polyurethane), EPS (expanded polystyrene), XPS (extruded polystyrene foam), or PE (polyethylene).

[0044] Specifically, in one embodiment, the thermal break connector 300 is made of PU (polyurethane), because PU has a low thermal conductivity, which can significantly reduce heat conduction and improve the thermal insulation performance of the thermal break connector. Furthermore, PU (polyurethane) has a low density, which can reduce the overall weight of the sliding door 1. When the sliding door is frequently opened and closed or subjected to wind pressure vibration, PU (polyurethane) can absorb impact energy through elastic deformation, reducing fatigue damage to metal components.

[0045] In the second embodiment, the thermal break connector 300 is made of EPS (expanded polystyrene). This is because EPS has a low thermal conductivity, which can effectively block the thermal bridging effect and reduce energy loss through the thermal break connector 300. Moreover, EPS is inexpensive, which can reduce the production cost of the thermal insulation hook 10.

[0046] In the third embodiment, the thermal break connector 300 is made of XPS (extruded polystyrene foam). This is because XPS has a low thermal conductivity, which can more efficiently block heat conduction and reduce the heat transfer coefficient of the thermal break connector 300. Furthermore, XPS has high compressive strength, allowing it to withstand long-term pressure on the sliding door (such as hardware pressure or wind load) without deformation, thus preventing insulation failure due to compression. This design is suitable for high-rise buildings, large-size glass, or sliding doors that require frequent opening and closing.

[0047] In the fourth embodiment, the thermal break connector 300 is made of PE (polyethylene). This is because PE has a low thermal conductivity, which can effectively block the thermal bridging effect and reduce energy conduction loss. Furthermore, PE has a low density, which helps to reduce the overall weight of the sliding door. Moreover, the molding process of PE is simple and low-cost, making it suitable for large-scale production.

[0048] Optionally, the first pressure wire member 210 is provided with a weight reduction cavity 211. That is, the first pressure wire member 210 is similar to a square tube, and the cavity inside the square tube is the weight reduction cavity 211. Such a first pressure wire member 210 has strong bending and torsional resistance, which is beneficial to improve the strength of the first pressure wire member 210 while reducing the weight of the first pressure wire member 210, thereby reducing the weight of the heat insulation hook 10.

[0049] In one embodiment, the first pressure member 210 engages with the hook body 100, and the formed mounting groove 130 facilitates the installation of the glass 20. However, this solution is not limited to this. In other embodiments, the first cavity wall is provided with a first pressure member 210 and a second pressure member 220 spaced apart, the mounting groove 130 is formed between the first pressure member 210 and the second pressure member 220, and the first pressure member 210 and the second pressure member 220 are respectively welded to the first cavity wall.

[0050] Furthermore, the first pressure member 210 is provided with a first locking part and a second locking part at intervals along the arrangement direction of the first pressure member 210 and the second pressure member 220. The first cavity wall is provided with a first locking engagement part and a second locking engagement part corresponding to the first locking part and the second locking part, respectively. Such a locking structure is more stable and helps to reduce the probability of the first pressure member 210 shaking.

[0051] Furthermore, the second snap-fit ​​part is fitted with a round rubber strip that contacts the second snap-fit ​​mating part, which ensures a good sealing effect, provides a cushioning effect, and enhances reliability. The second snap-fit ​​part has a side-opening round groove, within which the round rubber strip is fitted.

[0052] In one embodiment, the hook body 100 is provided with a reinforcing cavity 140, and a reinforcing member 600 is provided in the reinforcing cavity 140. The first sidewall 110 and the second sidewall 120 are respectively formed on the adjacent sidewalls of the reinforcing cavity 140. The technical solution of this utility model provides a reinforcing cavity 140 on the hook body 100 and a reinforcing member 600 in the reinforcing cavity 140. It can be understood that the reinforcing member 600 increases the local or overall geometric stability of the reinforcing cavity 140, thereby improving the ability of the hook body 100 to resist deformation caused by external loads (such as wind pressure, impact or vibration), and thus improving the strength of the hook body 100.

[0053] In one embodiment, the reinforcing member 600 includes multiple reinforcing plates disposed within the reinforcing cavity 140. It can be understood that the reinforcing plates locally strengthen the reinforcing cavity 140, thereby increasing its stability and ultimately enhancing the strength of the hook body 100. Furthermore, during actual assembly, the number of reinforcing plates can be determined based on wind pressure calculations. This ensures that the hook body 100 is strong enough to withstand the external environmental pressure of its operating environment while reducing the number of reinforcing plates, thus lowering the weight and production cost of the insulated hook 10.

[0054] Furthermore, in one embodiment, multiple reinforcing plates are spaced apart within the reinforcing cavity 140, that is, the reinforcing plates are arranged parallel to each other along the longitudinal or transverse direction of the reinforcing cavity 140, forming a stacked or strip-like structure. This arrangement is easy to process and install. Of course, this solution is not limited to this; in other embodiments, multiple reinforcing plates may also be arranged intersectingly within the reinforcing cavity 140.

[0055] In the second embodiment, among the plurality of reinforcing plates, two adjacent reinforcing plates are arranged in a V-shape. That is, two adjacent reinforcing plates and the cavity wall of the reinforcing cavity 140 together form a triangular cavity. In this way, the amount of material used is reduced under the same strength through the leverage effect of the geometric shape.

[0056] Furthermore, in the second embodiment, the reinforcing member 600 is configured as a reinforcing column, and the outer peripheral surface of the reinforcing column abuts against the inner sidewall of the reinforcing cavity 140. In this way, the reinforcing column can be used to support the strength of the reinforcing cavity 140, thereby strengthening the strength of the hook body 100.

[0057] Furthermore, the reinforcing column can be a solid column. Specifically, when the reinforcing column and the reinforcing cavity 140 are made of the same material, they can be integrally injection molded. This further strengthens the hook body 100 while reducing processing steps. Alternatively, they can be molded separately first and then the reinforcing column is installed into the reinforcing cavity 140. Of course, the reinforcing column and the reinforcing cavity 140 can also be made of different materials. This solution is not limited to this. In other embodiments, the reinforcing column can also be a hollow tube, with the outer wall of the hollow tube abutting against the inner wall of the reinforcing cavity 140. In this case, the wall thickness of the hollow tube can be selected according to the wind pressure of the operating environment and the magnitude of the possible impact force, thus ensuring the strength of the reinforcing cavity 140, that is, ensuring the strength of the hook body 100 while reducing the weight of the hook structure.

[0058] Reference Figure 1 and Figure 2 The present invention also proposes a sliding door 1, which includes a heat-insulating hook 10. The specific structure of the heat-insulating hook 10 is as described in the above embodiments. Since the 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.

[0059] Optionally, the hook structure 10 used on the outdoor sliding door is also provided with a reinforcing tube 700. The reinforcing tube 700 is provided on the third side wall opposite to the hook body 100 and the second side wall 120 to improve the strength of the hook structure 10 to resist wind pressure. A steel square tube can be added inside the reinforcing tube 700 according to the wind pressure calculation results of the usage environment.
