Description

Technical Field

[0001] The invention relates to the technical field of doors and windows, and in particular to a green energy-saving door and window with heat-insulating teeth. Background Art

[0002] As the world pays more and more attention to environmental protection and energy conservation, the construction industry is also constantly exploring and practicing green energy-saving technologies. As an important part of a building, the thermal insulation performance and energy-saving effect of doors and windows have a vital impact on the energy consumption and indoor comfort of the entire building. Traditional door and window designs have certain limitations in thermal insulation performance, especially in high temperature or cold environments. The temperature difference between indoors and outdoors can easily lead to rapid transfer of heat or cold, thereby increasing the energy consumption of air conditioning or heating equipment, and also affecting the comfort of the indoor environment.

[0003] In order to solve the above problems, various new green energy-saving door and window design solutions have been proposed. Among them, the design of doors and windows with heat-insulating teeth has attracted much attention due to its unique heat-insulating mechanism and high energy-saving effect. The design principle of heat-insulating teeth is to set a series of raised tooth structures on the frames of doors and windows. These tooth structures can form an effective heat-insulating barrier to reduce the transfer of indoor and outdoor heat. At the same time, the tooth-cutting strip is to roll the notch part of the aluminum alloy profile into the heat-insulating strip to increase the contact strength between the aluminum material and the heat-insulating strip, which is the key to ensure the tightness and verticality of the finished profile.

[0004] However, in the existing door and window manufacturing process, the setting of the heat-insulating teeth is usually completed by rolling the teeth in the notch portion where the aluminum alloy profile penetrates the heat-insulating strip; The gear rolling process may cause the contact area between the insulation teeth and the insulation strip to be too large. Excessive contact area means that the friction between the two will also increase, which will have an adverse effect on the installation process of the insulation strip. During the installation process, the increased friction makes it difficult for the insulation strip to slide smoothly into place, which not only reduces the installation efficiency, but may also cause the insulation strip to deform or be damaged due to excessive friction.

[0005] In view of this, this application is hereby filed. Summary of the invention

[0006] The purpose of the present invention is to provide a green energy-saving door and window with insulation teeth. By designing the combination of straight racks and bevel racks, it can limit the installation of insulation strips and improve the stability of the installation of insulation strips. At the same time, the bevel racks can slide relative to the straight racks, thereby reducing the contact area with the insulation strips when the insulation strips are inserted, thereby reducing the friction during installation, making it more convenient to insert the insulation strips, and also improving the installation efficiency and the quality of the finished product, so as to solve the problems raised in the above-mentioned background technology.

[0008] Furthermore, the top surface of the spur rack is also provided with a linkage mechanism for controlling the helical rack to slide on the spur rack; The linkage mechanism comprises: A linkage member, the middle part of which is rotatably connected to the spur rack through a torque shaft, and one end of the linkage member is provided with a linkage rod perpendicular to the linkage member; The linkage groove is set along the length direction of the helical rack, and the linkage rod extends into the linkage groove and slides with it, so that the teeth of each helical rack are close to the teeth of the straight rack and abut against the insulation strip in the initial state of the torque shaft.

[0009] Furthermore, a second fixing groove for the heat insulation strip to penetrate into is provided inside the glass installation frame, and a slot for the heat insulation tooth assembly to penetrate into is provided on the side wall of the second fixing groove; Also includes, The falcon block extends outward from the bottom of the slot perpendicular to the slot, forming a space for the spur rack to move toward or away from the bottom of the slot; The falcon groove is located at the front end of the spur rack and extends in a direction perpendicular to the length of the spur rack, and is used for the falcon block to be inserted to limit the displacement of the spur rack in the front-rear direction; The straight slot is extended perpendicularly to the length direction of the straight rack. In the initial state, the torque shaft is located at the leftmost end of the straight slot; An eccentric shaft is vertically arranged at the other end of the linkage member, and its extension direction is opposite to that of the linkage rod; The eccentric opening is arranged at the top of the spur rack. The eccentric opening is arranged in an arc shape, and the curvature radius thereof is greater than the distance from the torque shaft to the eccentric shaft.

[0010] Furthermore, it also includes: The guide groove is arranged at the top of the spur rack and is arranged in an arc shape, and its curvature radius is equal to the distance from the torque shaft to the linkage rod; The guide rod extends downward perpendicularly to the bottom surface of the helical rack and extends into the guide groove to be slidably connected therewith.

[0011] Furthermore, a plurality of straight teeth are arranged on the side wall of the straight rack, and the plurality of straight teeth are evenly distributed along the length direction of the straight rack; a first bevel tooth is arranged on one of the bevel racks, and a second bevel tooth is arranged on the other bevel rack.

[0012] Furthermore, the first bevel teeth are arranged to extend upwardly along one of the bevel rack bodies, and the second bevel teeth are arranged to extend downwardly along the other bevel rack body.

[0013] Furthermore, a plurality of linkage mechanisms are arranged between each of the helical racks and the spur racks, and the plurality of linkage mechanisms are evenly distributed along the length direction of the spur racks.

[0014] Furthermore, the mounting groove is opened along the length direction of the glass mounting frame, and a plurality of the mounting grooves are provided, and the plurality of mounting grooves are evenly distributed along the thickness direction of the glass mounting frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a heat-insulating tooth assembly inside the door and window, and the heat-insulating tooth assembly adopts a structural design of a combination of a straight rack and two oblique racks. The oblique rack can slide relative to the straight rack, and the heat-insulating strip inserted into the door and window can be limited in the left and right directions by the straight rack. The heat-insulating strip inserted into the door and window can be limited in the front and back directions by arranging teeth with different inclination directions on the two oblique racks. The torsion shaft pushes the oblique rack to press against the side wall of the heat-insulating strip, thereby preventing the heat-insulating strip from sliding after installation and improving the stability of the heat-insulating strip installed inside the door and window.

[0016] 2. The present invention applies a thrust or pull force to the bevel rack to make it slide on the spur rack. During the sliding process, the bevel rack drives the linkage rod to overcome the torque of the torque shaft to drive the linkage member to rotate. The rotation of the linkage member is used to generate a lateral component of force on the bevel rack, so that the bevel rack is displaced rearward along the spur rack to reduce the contact area between the bevel rack and the insulation strip, thereby reducing the friction during the installation process, making it more convenient to thread the insulation strip, and also improving the installation efficiency and the quality of the finished product.

[0017] 3. In the present invention, the radius of curvature of the eccentric opening is larger than the distance from the torque shaft to the eccentric shaft, which ensures that the eccentric shaft can slide smoothly in the eccentric opening during the movement of the torque shaft without getting stuck. The rotation of the torque shaft causes relative movement between it and the eccentric shaft. Due to the setting of the eccentric opening and as the torque shaft moves in the straight slot, it applies a thrust to the spur rack. Due to the restrictions of the falcon slot and the falcon block, the spur rack can only move along the direction of the bottom of the slot, so that the spur rack can move closer to the bottom of the slot, thereby increasing the space for the insulation strip to pass through, and further improving the installation efficiency of the insulation strip.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 10 The present invention provides a technical solution: a green energy-saving door and window with heat-insulating teeth, comprising a window frame 1, and a glass installation frame 2 matching the window frame 1, the glass installation frame 2 being hinged to the window frame 1 through a hinge 4; the glass installation frame 2 is surrounded by four aluminum profiles, and each aluminum profile has a receiving cavity for installing a heat-insulating strip 6; The cavity wall of the accommodating cavity is provided with mounting grooves which are opposite to each other in the form of notches, and the heat-insulating tooth assembly 5 is installed inside the mounting groove; The heat-insulating tooth assembly 5 comprises: A spur rack 51 is arranged at the bottom of the installation slot, and the teeth of the spur rack 51 abut against the side wall of the thermal insulation strip 6, so as to limit the left and right directions of the thermal insulation strip 6; At least two oblique racks 514 are slidably arranged relative to the straight rack 51 . The teeth of the two oblique racks 514 are arranged in opposite directions. The teeth of the oblique racks 514 abut against the side wall of the insulation strip 6 to limit the insulation strip 6 in the front-to-back direction.

[0022] Specifically, by setting an insulation tooth assembly 5 inside the glass mounting frame 2, and the insulation tooth assembly 5 adopts a structural design of a combination of a straight rack 51 and two oblique racks 514, the oblique rack 514 can slide relative to the straight rack 51, and the straight rack 51 can be used to limit the left and right directions of the insulation strip 6 inserted into the accommodating cavity. By setting teeth with opposite arrangement directions on the two oblique racks 514, the front and back directions of the insulation strip 6 inserted into the accommodating cavity can be limited, thereby preventing the insulation strip 6 from sliding after installation and improving the stability of the insulation strip 6 installed inside the doors and windows.

[0023] See also Figure 6-Figure 10 , the top surface of the spur rack 51 is also provided with a linkage mechanism for controlling the helical rack 514 to slide on the spur rack 51; The linkage agencies include: A linkage member 58, the middle portion of which is rotatably connected to the spur rack 51 via a torque shaft 511, and a linkage rod 59 perpendicular to the linkage member 58 is provided at one end of the linkage member 58; The linkage groove 510 is set to penetrate along the length direction of the oblique rack 514, and the linkage rod 59 extends into the linkage groove 510 and slides with it, so as to make the teeth of each oblique rack 514 close to the teeth of the straight rack 51 and abut against the insulation strip 6 when the torque shaft 511 is in the initial state.

[0024] Specifically, a thrust or a pull is applied to the bevel rack 514 to make it slide on the spur rack 51. During the sliding process, the bevel rack 514 drives the linkage rod 59 to overcome the torque of the torque shaft 511 to drive the linkage member 58 to rotate. The rotation of the linkage member 58 generates a lateral component of force on the bevel rack 514, causing the bevel rack 514 to move rearwardly along the spur rack 51 to reduce the contact area between the bevel rack 514 and the thermal insulation strip 6, thereby reducing the friction during the installation process, making it easier to thread the thermal insulation strip 6, and improving the installation efficiency and the quality of the finished product.

[0025] It should be noted that: the torsion shaft 511 includes a sliding shaft seat slidably set inside the straight groove 513, a shaft rod connected to the middle position of the linkage member 58, and a torsion spring sleeved on the bottom end of the shaft rod; the shaft rod is rotatably connected to the inside of the sliding shaft seat, one end of the torsion spring is fixedly connected to the outer wall of the bottom end of the shaft rod, and the other end of the torsion spring is fixedly connected to the inner wall of the sliding shaft seat; the torsion spring is made of a soft and tough elastic material, and then when used, when the torsion spring is in the initial state, it can provide torsion for the shaft rod, thereby fixing the linkage member 58 in a certain position in a static manner, this state can ensure that the teeth of the bevel rack 514 are tightly against the insulation strip 6, so as to achieve the expected effect of limiting the forward and backward displacement of the insulation strip 6, when the linkage member 58 starts to rotate, the torsion spring is deformed when subjected to external force, stores elastic potential energy, and returns to its original state after the external force is removed, and will quickly pull the linkage member 58 back to its original position.

[0026] See also Figure 5-Figure 9 A second fixing groove 202 for the heat insulation strip 6 to penetrate is provided inside the glass installation frame 2, and a slot 203 for the heat insulation tooth assembly 5 to penetrate is provided on the side wall of the second fixing groove 202; Also includes, The falcon block 204 extends outward from the bottom of the slot 203 perpendicularly to form a space for the spur rack 51 to move toward or away from the bottom of the slot 203; The falcon groove 57 is located at the front end of the spur rack 51 and extends in a direction perpendicular to the length of the spur rack 51, and is used for the falcon block 204 to be inserted to limit the displacement of the spur rack 51 in the front-rear direction; The straight slot 513 is extended perpendicularly to the length direction of the straight rack 51. In the initial state, the torque shaft 511 is located at the leftmost end of the straight slot 513; The eccentric shaft 512 is vertically arranged at the other end of the linkage member 58, and its extension direction is opposite to that of the linkage rod 59; The eccentric opening 55 is disposed at the top of the spur rack 51 . The eccentric opening 55 is disposed in an arc shape, and the radius of curvature thereof is greater than the distance from the torque shaft 511 to the eccentric shaft 512 .

[0027] Specifically, the radius of curvature of the eccentric opening 55 is greater than the distance from the torque shaft 511 to the eccentric shaft 512, which ensures that the eccentric shaft 512 can slide smoothly in the eccentric opening 55 during the movement of the torque shaft 511 without getting stuck. The rotation of the torque shaft 511 causes relative movement between it and the eccentric shaft 512. Due to the setting of the eccentric opening 55 and as the torque shaft 511 moves in the straight slot 513, it applies a thrust to the spur rack 51. Due to the restrictions of the falcon slot 57 and the falcon block 204, the spur rack 51 can only move along the direction of the bottom of the slot 203, so that the spur rack 51 can move closer to the bottom of the slot 203, thereby increasing the space for the insulation strip 6 to pass through, and further improving the installation efficiency of the insulation strip 6. It should be noted that: In the initial state: The spur rack 51 is inserted into the slot 203, and the front end of the spur rack 51 is provided with a spur groove 57 which cooperates with the spur block 204 in the slot 203, thereby limiting the displacement of the spur rack 51 in the front-to-back direction, i.e., the length direction of the slot 203; The torque shaft 511 is located at the leftmost end of the straight slot 513, which is an initial position for subsequent movement and transmission preparation; The eccentric shaft 512 is vertically arranged at the other end of the linkage member 58, opposite to the extension direction of the linkage rod 59, and is in a standby state; Mobile trigger: When the spur rack 51 needs to be moved, the bevel rack 514 is pulled to move along the rear of the spur rack 51. During the movement, the bevel rack 514 drives the linkage rod 59 to rotate through the linkage groove 510, and the linkage rod 59 drives the linkage member 58 to rotate. The movement of the linkage 58 drives the eccentric shaft 512 to rotate. Since the radius of curvature of the eccentric opening 55 is greater than the distance from the torque shaft 511 to the eccentric shaft 512, the rotation of the eccentric shaft 512 is converted into linear motion or compound motion. Due to the setting of the eccentric opening 55, the rotation of the eccentric shaft 512 causes relative movement between it and the torque shaft 511. The eccentric shaft 512 can move along an arc trajectory under the guidance of the eccentric opening 55; and the torque shaft 511 can move along a straight trajectory under the guidance of the straight slot 513. Furthermore, since the curvature radius of the eccentric opening 55 is greater than the distance from the torsion shaft 511 to the eccentric shaft 512, and as the torsion shaft 511 moves in the straight slot 513, it will exert a thrust on the spur rack 51. Due to the restrictions of the falcon slot 57 and the falcon block 204, the spur rack 51 can only move along the bottom of the slot 203, thereby increasing the space for the insulation strip 6 to pass through, and further improving the installation efficiency of the insulation strip 6. The block 204 is embedded in the slot 57 to form a mechanical interlock, so that the connection between the spur rack 51 and the slot 203 is more stable and not easy to loosen or fall off. This structure enhances the connection strength between the components and improves the stability and reliability of the overall structure. This ensures that the spur rack 51 can be accurately positioned when inserted into the slot 203, thereby avoiding installation deviation of the heat insulation strip 6 caused by position deviation; It should be noted that due to the design of the block 204 and the slot 57, the installation process is simpler and faster. The block 204 can be automatically embedded in the slot 57 by simply aligning the spur rack 51 with the slot 203 and gently pushing it in, without the need for additional fasteners or complicated installation steps.

[0028] See also Fig. 9 , also includes, The guide groove 56 is arranged at the top of the spur rack 51 and is arranged in an arc shape, and its curvature radius is equal to the distance from the torque shaft 511 to the linkage rod 59; The guide rod extends downward perpendicular to the bottom surface of the oblique rack 514 and extends into the guide groove 56 to be slidably connected thereto.

[0029] Specifically, the spur rack 51 serves as the main supporting and guiding structure, and an arc-shaped guide groove 56 is provided on the top thereof, and the curvature radius of the guide groove 56 is equal to the horizontal distance between the torque shaft 511 and the linkage rod 59. This design ensures that when the bevel rack 514 slides on the spur rack 51, it can maintain a stable motion trajectory and precise relative position.

[0030] A guide rod extends vertically downward from the bottom surface of the helical rack 514, and the guide rod is tightly inserted into the guide groove 56 at the top of the spur rack 51, and forms a sliding connection with the guide groove 56. This sliding connection not only limits the degree of freedom of the helical rack 514 in the left and right directions, but also guides the helical rack 514 to slide along a predetermined trajectory through the arc shape of the guide groove 56.

[0031] See also Fig. 9 and Fig.10A plurality of straight teeth 52 are arranged on the side wall of the straight rack 51, and the plurality of straight teeth 52 are evenly distributed along the length direction of the straight rack 51; a first bevel tooth 53 is arranged on one of the bevel racks 514, and a second bevel tooth 54 is arranged on the other bevel rack 514; the first bevel tooth 53 is extended upward along the body of one of the bevel racks 514, and the second bevel tooth 54 is extended downward along the body of the other bevel rack 514.

[0032] Specifically, the first oblique teeth 53 can be provided to lock the insulation strip 6 when it is pulled out, and the oblique teeth can be provided to lock the insulation strip 6 when it is inserted, and then the first oblique teeth 53 and the second oblique teeth 54 can be used to lock the insulation strip 6 when it slides forward and backward, thereby preventing the insulation strip 6 from being displaced after installation, and improving the stability of the installation of the insulation strip 6. It should be noted that: the first bevel teeth 53 and the second bevel teeth 54 are both arranged in an inclined state, so that the teeth arranged at the front and rear ends of the bevel rack 514 are in an outward-facing "X" structure. Of course, as another arrangement method, the first bevel teeth 53 and the second bevel teeth 54 are arranged in an inclined state. This design can make the teeth at the front and rear ends of the bevel rack 514 in an inward-facing "X" structure. The two design schemes can achieve the same effect.

[0033] See also Figure 7 and Fig.10 Multiple linkage mechanisms are arranged between each oblique rack 514 and the spur rack 51 , and the multiple linkage mechanisms are evenly distributed along the length direction of the spur rack 51 .

[0034] Specifically, in order to improve the stability and accuracy of the helical rack 514 sliding on the spur rack 51, multiple sets of linkage mechanisms are arranged between each helical rack 514 and the spur rack 51. These linkage mechanisms are evenly distributed along the length direction of the spur rack 51 to form a stable support and transmission system.

[0035] When an external driving force acts on the bevel rack 514, it is transmitted to multiple groups of linkage mechanisms. These linkage mechanisms work independently but in coordination with each other to jointly push the bevel rack 514 to slide along the spur rack 51. Since the multiple groups of linkage mechanisms are evenly distributed along the length direction of the spur rack 51, they can ensure that the bevel rack 514 is always uniformly and stably supported and thrust during the sliding process, thereby improving the smoothness of the sliding of the bevel rack 514 and reducing the risk of wear and deformation caused by excessive force at a single point. At the same time, the multiple groups of linkage mechanisms can also share the external driving force to a certain extent, so that the load borne by each linkage mechanism is more uniform, which helps to extend the service life of the linkage mechanism and the entire insulation tooth assembly 5, and improve its reliability and durability.

[0036] As the bevel rack 514 slides, the teeth with different inclination directions arranged thereon will come into close contact with the insulation strip 6 penetrating into the inside of the door and window, and limit it in the front and rear directions. Due to the coordinated action of multiple groups of linkage mechanisms, this limiting action is more stable and reliable, and can effectively prevent the insulation strip 6 from sliding or loosening after installation.

[0037] See also Figure 8 and Fig. 9 The mounting groove is opened along the length direction of the glass mounting frame 2 , and a plurality of mounting grooves are provided, and the plurality of mounting grooves are evenly distributed along the thickness direction of the glass mounting frame 2 .

[0038] Specifically, the mounting grooves are opened along the length direction of the glass mounting frame 2 so that the mounting grooves are parallel to the long sides of the glass mounting frame 2 , so that the mounting grooves can be evenly distributed on the mounting frame, providing multiple fixed positions for the installation of the insulation tooth assembly 5 .

[0039] See also Figure 3 A limiting groove 201 is processed on the inner side of the glass installation frame 2, and a hollow glass 3 is installed inside the limiting groove 201. A plurality of first fixing grooves 101 that are symmetrically arranged on the left and right are respectively opened in the window frame 1, and a plurality of second fixing grooves 202 that are symmetrically arranged on the left and right are respectively opened in the glass installation frame 2. The insulation strip 6 is installed between the first fixing groove 101 that is symmetrical on the left and right and the second fixing groove 202 that is symmetrical on the left and right. A slot 203 is opened at the bottom of the first fixing groove 101 and the second fixing groove 202, and the insulation tooth assembly 5 is inserted into the inside of the slot 203.

[0040] Specifically, the addition of the heat insulation strip 6 effectively blocks the heat conduction between the window frame 1 and the glass installation frame 2, preventing the indoor heat from leaking out in winter and the outside heat from entering the room in summer, thereby achieving a good heat insulation effect, which is of great significance for improving indoor comfort and saving energy costs; The design of the left-right symmetrical first fixing groove 101 and the second fixing groove 202, and the structure of the heat insulation tooth assembly 5 plugged into the slot 203, make the installation of the heat insulation strip 6 more stable and not easy to loosen or fall off. This stable structure ensures the overall stability and safety of the door and window; Through the close cooperation between the heat insulation strip 6 and the heat insulation tooth assembly 5, the design of the heat insulation tooth effectively blocks the heat conduction path between the door and window profiles, reduces the heat exchange between indoor and outdoor, and achieves good sealing performance, which helps to prevent rainwater, dust and other foreign substances from entering the room, keeping the room dry and clean; It should be noted that: in order to facilitate the fixing of the thermal insulation tooth assembly 5 inside the first fixing groove 101, a groove identical to the slot 203 should be opened on the inner wall of the first fixing groove 101. The thermal insulation tooth assembly 5 can be conveniently inserted into the first fixing groove 101 through the groove set on the inner wall of the first fixing groove 101. Since the window frame 1 and the glass installation frame 2 are both provided with thermal insulation tooth assemblies 5 for fixing the thermal insulation strip 6, it can be ensured that the window frame 1 and the glass installation frame 2 both have a thermal insulation tooth structure.

[0041] See also Figure 2 and Figure 3 A first receiving groove 102 symmetrically arranged on the left and right is respectively opened in the window frame 1, and a second receiving groove 205 symmetrically arranged on the left and right is respectively opened in the glass installation frame 2. The first thermal insulation cotton 7 is installed in the second receiving groove 205, and the second thermal insulation cotton 8 is installed in the first receiving groove 102.

[0042] Specifically, the first thermal insulation cotton 7 and the second thermal insulation cotton 8 arranged inside the window frame 1 can achieve the effect of heat insulation and heat preservation, and can effectively block the cold air in winter and the hot air in summer from entering the room, thereby reducing indoor temperature fluctuations and reducing the energy consumption of heating and air conditioning; the first thermal insulation cotton 7 and the second thermal insulation cotton 8 have a sound insulation layer inside that can absorb excess sound waves, reduce the propagation of noise, and improve the quietness of the room.

[0043] See also Figure 1-Figure 3 A first flange portion 103 is processed at the right side of the window frame 1, and a first buffer rubber strip 104 is embedded and installed inside the first flange portion 103. The first buffer rubber strip 104 is in contact with the side wall of the glass mounting frame 2. A second flange portion 206 is processed at the left side of the glass mounting frame 2, and a second buffer rubber strip 207 is embedded and installed inside the second flange portion 206. The second buffer rubber strip 207 is in contact with the side wall of the window frame 1.

[0044] Specifically, when the doors and windows are in a closed state, the first flange portion 103 and the first buffer rubber strip 104 provided on the side wall of the window frame 1 will fit the side wall of the glass mounting frame 2, and the second flange portion 206 and the second buffer rubber strip 207 provided on the side wall of the glass mounting frame 2 will fit the side wall of the window frame 1. The first flange portion 103 and the second flange portion 206 can achieve a two-way sealing effect. The sealing performance enables the energy-saving doors and windows to block the high temperature, cold and noise outdoors, maintain a stable indoor temperature and a good indoor environment, and help provide a quieter and tidier living environment, thereby greatly improving living comfort. At the same time, the improvement in sealing performance means that the doors and windows can more effectively prevent the exchange of cold and hot air, reduce the transfer of indoor and outdoor temperatures, help save energy, and reduce energy waste.

[0045] Working principle: When installing the heat insulation strip 6, the assembler first inserts the heat insulation tooth assembly 5 into the grooves and slots 203 correspondingly opened in the first fixing groove 101 and the second fixing groove 202, and then pushes the spur rack 51. The falcon groove 57 and the falcon block 204 at the front end of the spur rack 51 cooperate and lock, which can limit the forward and backward sliding of the spur rack 51, and then pulls the bevel rack 514 with the second bevel teeth 54 to move horizontally toward the rear end of the spur rack 51. During the movement of the bevel rack 514, the linkage groove 510 thereon will drive the linkage rod 59 to rotate. When the linkage rod 59 rotates to a horizontal state, the linkage member 58 cooperates with the linkage rod 59 to generate a lateral component force on the bevel rack 514, thereby causing the bevel rack 514 to move obliquely backward. In this process, the teeth of the bevel rack 514 will move toward the rear of the spur teeth 52. At this time, the first bevel teeth 5 3 is staggered between the second helical teeth 54 and the straight teeth 52. When the helical rack 514 moves to the limit position of the rotation of the linkage member 58, force is applied to pull the helical rack 514 to move horizontally toward the rear end of the straight rack 51, and the eccentric shaft 512 slides along the inner wall of the eccentric opening 55. Since there is an eccentric distance between the eccentric opening 55 and the rotation center of the linkage member 58, the torque shaft 511 slides along the inside of the straight slot 513 and cooperates with the eccentric opening 55 through the eccentric shaft 512 to drive the straight rack 51 to slide toward the inside of the slot 203. At this time, the distance between the two straight racks 51 of the heat-insulating tooth assembly 5 is increased. Due to the increase in the distance, the friction between the left and right side walls of the heat-insulating tooth assembly 5 and the heat-insulating tooth assembly 5 is reduced when the heat-insulating strip 6 penetrates into the first fixed groove 101, making it more convenient for the heat-insulating strip 6 to penetrate into the first fixed groove 101. When the heat insulation strip 6 is inserted, the eccentric shaft 512 will rotate in the opposite direction to cooperate with the eccentric opening 55 to drive the spur rack 51 to move toward the heat insulation strip 6 by pushing the oblique rack 514 to slide toward the front end of the spur rack 51. At this time, the spur teeth 52 of the spur rack 51 can be tightly in contact with the left and right side walls of the heat insulation strip 6. The heat conduction path between the glass installation frame 2 and the heat insulation strip 6 is effectively blocked by the cooperation of the set spur rack 51 and the spur teeth 52, thereby reducing the heat exchange between indoor and outdoor, and improving the heat insulation effect of the glass installation frame 2. As the bevel rack 514 continues to slide toward the front end of the straight rack 51, the linkage groove 510 will drive the linkage rod 59 to move, thereby resetting the linkage member 58. When the linkage member 58 is reset, the teeth of the bevel rack 514 will fit against the side wall of the thermal insulation strip 6. Since the thermal insulation strip 6 has been installed in place, when the thermal insulation strip 6 moves forward, the first bevel teeth 53 are subjected to force to fix the forward position of the thermal insulation strip 6. When the thermal insulation strip 6 moves backward, the second bevel teeth 54 are subjected to force to fix the backward position of the thermal insulation strip 6. Then, the teeth of the bevel rack 514 can lock the forward and backward sliding of the thermal insulation strip 6, thereby further improving the stability of the installation of the thermal insulation strip 6.
