Description

Technical Field

[0001] This utility model belongs to the field of modular door technology, specifically, it relates to an assembled door. Background Technology

[0002] Modular door panels are door structures that enable rapid assembly and disassembly through modular design. They are composed of multiple independent modules (such as door frames, door panels, connectors, etc.) combined by mechanical connections (such as rivets, screws, buckles, etc.), without the need for complex welding or on-site processing.

[0003] The prior art discloses an assembled door structure (CN214943677U), including a door frame and door panels fixed on both sides of the door frame. The door frame includes four splicable assembled door panel profiles and several right-angle connectors set inside the door panel profiles for connecting adjacent door panel profiles. The middle of the door panel profile is recessed to accommodate the right-angle connectors and to limit the assembly of the door panels. The assembled door structure of this utility model, by setting a door frame with right-angle connectors for limiting connection, facilitates the disassembly, assembly, and transportation of the door frame. The door panel profile is provided with an installation groove, and a limiting plate is formed on the wall of the installation groove, which can be used for limiting and locking the right-angle connectors, facilitating quick positioning and assembly. The door panels are made of hollow board, which can reduce weight. Fixing parts are installed on the door panel profiles to facilitate the later installation of lock cylinders and related components.

[0004] The search revealed that the existing technology has limitations in installation and use. It can only install a limited range of door shapes in a single environment and the installation efficiency is low. Furthermore, due to the assembly method, the existing technology does not take into account the buffering effect when the door panel is in use, which makes it easy for the door panel to collide when it is opened, causing damage to the door panel and affecting its subsequent use.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An assembled door includes a side door frame, a horizontal door frame, and a door panel. The side door frame is snapped into one corner of the horizontal door frame, and the door panel is movably disposed between the side door frame and the horizontal door frame. A buffer member for buffering collisions is movably disposed on each side of the door panel.

[0008] The brake mounting assembly includes two sets of brake mounting assemblies symmetrically arranged inside the door panel. Each brake mounting assembly includes a connecting column, a connecting rod, a gear, a rack, and a brake block. A brake block is fixedly connected to each end of the connecting rod, and a rack is fixedly connected to one side of the connecting rod. Two connecting columns are symmetrically arranged vertically, and two connecting rods are symmetrically arranged around the connecting columns. The rack is rotatably arranged inside the door panel.

[0009] In a preferred embodiment of the present invention, the buffer includes a buffer pad and a support frame. The support frame is fixedly disposed on the side of the buffer pad near the door panel, and the support frame is movably disposed inside the side wall of the door panel.

[0010] In a preferred embodiment of this utility model, a square buffer groove is provided on both the front and back sides of the door panel, and the support frame slides in the buffer groove accordingly. A buffer spring is provided at each of the four corners of the support frame near the buffer groove, and the support frame is elastically connected to the buffer groove through the buffer springs at the four corners.

[0011] In a preferred embodiment of this utility model, both the inner side of the side door frame near the door panel and the inner side of the horizontal door frame near the door panel are provided with sliding grooves. Each end of the side door frame is fixed with a stop block, which engages with the sliding groove of the horizontal door frame. One side of the horizontal door frame and one end of the side door frame are provided with a latch, and the other side of the horizontal door frame and the other end of the side door frame are fixed with a locking block, which engages with the latch. One end of the sliding groove of the horizontal door frame is provided with a hinge hole, which engages with the connecting shaft.

[0012] In a preferred embodiment of this utility model, a telescopic groove and a braking groove are respectively provided at the four corners of the door panel. The connecting column slides in the telescopic groove and the braking block slides in the braking groove. Square limiting grooves are provided in both sides of the door panel. One end of the braking groove communicates with the limiting groove, and the center of the braking groove communicates with the telescopic groove.

[0013] In a preferred embodiment of this utility model, a compression spring is fixedly provided between the connecting column and the telescopic groove. The connecting column is elastically connected to the telescopic groove through the compression spring, and the brake blocks on both sides of the connecting column jointly clamp and limit the connecting column.

[0014] In a preferred embodiment of this utility model, the center of the limiting groove is rotatably connected to a gear, and two racks are symmetrically arranged vertically around the gear. Each of the two racks is fixedly connected to a connecting rod, and both racks are meshed with the same gear for transmission. One side of one of the connecting rods is fixedly connected to a pull rod, and the pull rod passes through the door panel.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. By operating the braking installation assembly, the connecting columns at the four corners of the door panel can be extended as needed. By changing the shape of the door body, the number and placement of the horizontal and side door frames can be adjusted, so that the door panel and the two side door frames and the two horizontal door frames can form a hinged door or a sliding door. Without replacing a large number of parts, the environmental adaptability and usage flexibility of the door body are greatly improved, overcoming the problem of the single installation and use limitation of the existing technology. At the same time, the side door frames and the horizontal door frames can be quickly engaged through the cooperation of the abutment, the latch and the locking block. The braking installation assembly can extend and lock the connecting columns through the simple operation of the pull rod, so that the door panel can be quickly connected to the door frame. The operation is convenient and the installation efficiency is high, overcoming the problem of low installation efficiency of the existing technology.

[0017] 2. The buffers installed on both sides of the door panel allow the buffer pads to first contact and absorb part of the impact force when the door panel collides with the door frame or other objects during opening or closing. The support frame slides in the buffer groove and compresses the buffer spring, further converting the collision energy into the elastic potential energy of the spring. This greatly reduces the direct impact on the door panel, effectively avoids damage to the door panel, extends the service life of the door, and overcomes the problem of insufficient consideration of the buffering effect of the door panel during use in existing technologies.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] A type of assembled door, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it includes a side door frame 10, a horizontal door frame 11, and a door panel 12. The side door frame 10 is snapped into one corner of the horizontal door frame 11. The door panel 12 is movably disposed between the side door frame 10 and the horizontal door frame 11. A buffer member for buffering collisions is movably disposed on each side of the door panel 12.

[0030] The brake mounting assembly has two sets of brake mounting assemblies symmetrically arranged inside the door panel 12. Each brake mounting assembly includes a connecting column 19, a connecting rod 26, a gear 27, a rack 28, and a brake block 29. A brake block 29 is fixedly connected to each end of the connecting rod 26, and a rack 28 is fixedly connected to one side of the connecting rod 26. There are two connecting columns 19 symmetrically arranged vertically, and two connecting rods 26 symmetrically arranged about the center of the connecting column 19. The rack 28 is rotatably arranged inside the door panel 12.

[0031] Specifically, this device extends the connecting columns 19 at the four corners of the door panel 12 as needed by operating the braking installation components. By changing the shape of the door body, the number and placement of the horizontal door frame 11 and the side door frame 10 are adjusted, so that the door panel 12 and the two side door frames 10 and the two horizontal door frames 11 form a hinged door or a sliding door. Without replacing a large number of parts, it greatly improves the environmental adaptability and usage flexibility of the door body and overcomes the problem of the single installation and use limitation of the existing technology. The buffers set on both sides of the door panel 12 can buffer the collision between the door panel 12 and other objects during the opening or closing of the door panel 12, thereby greatly reducing the direct impact on the door panel 12, effectively avoiding damage to the door panel 12 and extending the service life of the door body.

[0032] like Figure 1 , Figure 2 and Figure 7As shown, the buffer includes a buffer pad 13 and a support frame 30. The support frame 30 is fixedly disposed on the side of the buffer pad 13 near the door panel 12, and the support frame 30 is movably disposed inside the side wall of the door panel 12.

[0033] like Figure 5 and Figure 7 As shown, a square buffer groove 24 is opened on both the front and back sides of the door panel 12. The cross-section of the buffer groove 24 is T-shaped. The support frame 30 slides in the buffer groove 24. A buffer spring 31 is provided at each of the four corners of the support frame 30 near the buffer groove 24. The support frame 30 is elastically connected to the buffer groove 24 through the buffer springs 31 at the four corners.

[0034] The working principle is as follows: the buffer pad 13 is made of elastic material, such as rubber or elastic foam, and is located on the outermost sides of the door panel 12 to directly bear the impact. The support frame 30 is a rigid structure and is fixedly set on the side of the buffer pad 13 close to the door panel 12. It supports and fixes the buffer pad 13. The shape of the support frame 30 matches the buffer groove 24 and can slide in the buffer groove 24 to prevent the support frame 30 from falling out of the buffer groove 24. When the buffer pad 13 is impacted, the impact force is transmitted to the buffer spring 31 through the support frame 30. The spring is compressed to absorb the energy, thereby achieving the buffering effect.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the side door frame 10 has a T-shaped structure. The inner side of the side door frame 10 near the door panel 12 and the inner side of the horizontal door frame 11 near the door panel 12 are both provided with sliding grooves 20. The sliding grooves 20 correspond to the size of the connecting column 19. A stop block 15 is fixed at each end of the side door frame 10. The stop block 15 is engaged in the sliding groove 20 of the horizontal door frame 11. A latch 16 is provided on one side of the horizontal door frame 11 and one end of the side door frame 10. A latch block 17 is fixed on the other side of the horizontal door frame 11 and the other end of the side door frame 10. The latch block 17 is engaged in the latch block 16. A hinge hole 18 is provided at one end of the sliding groove 20 of the horizontal door frame 11. The hinge hole 18 is engaged in the hinge of the connecting column 19.

[0036] The working principle is as follows: when assembly is required, the abutment 15 of the side door frame 10 is aligned with one end of the slide groove 20 of the horizontal door frame 11 and inserted. At the same time, the locking block 17 of the side door frame 10 is engaged with the locking slot 16 of the horizontal door frame 11, or the locking block 17 of the horizontal door frame 11 is engaged with the locking slot 16 of the side door frame 10, thereby achieving a stable engagement between the side door frame 10 and the horizontal door frame 11 at one corner. In this way, door frame frames of different sizes can be assembled as needed.

[0037] like Figure 3 and Figure 4As shown, a telescopic groove 21 and a braking groove 22 are respectively opened at the four corners of the door panel 12. The connecting column 19 slides in the telescopic groove 21, and the braking block 29 slides in the braking groove 22. The telescopic groove 21 is a columnar groove with an arch-shaped cross section, and the braking groove 22 is a square groove. Square limiting grooves 23 are opened in both sides of the door panel 12. One end of the braking groove 22 is connected to the limiting groove 23, and the center of the braking groove 22 is connected to the telescopic groove 21.

[0038] like Figure 4 , Figure 5 and Figure 6 As shown, a compression spring 25 is fixed between the connecting column 19 and the telescopic groove 21. The connecting column 19 is elastically connected to the telescopic groove 21 through the compression spring 25. The brake blocks 29 on both sides of the connecting column 19 clamp and limit the connecting column 19. The connecting column 19 is a nail-shaped column. A wave-shaped tooth groove is opened on the curved surface of the connecting column 19. The brake block 29 has a corresponding wave-shaped tooth inside, and the wave-shaped tooth corresponds to the locking wave-shaped tooth groove.

[0039] The working principle is as follows: In the initial state, when the lever 14 is not pulled, the brake block 29 engages with the wave-shaped toothed groove of the connecting rod 26. The connecting rod 19 is pressed by the compression spring 25, but due to the locking of the brake block 29, it cannot extend out of the telescopic groove 21. When it is necessary to extend the connecting rod 19, the lever 14 is pulled outward. The lever 14 drives the connecting rod 26 connected to it to move. The rack 28 on the connecting rod 26 moves accordingly. The rack 28 drives the gear 27 meshing with it to rotate. The gear 27 then drives the rack 28 on the other side to move in the opposite direction, thereby driving the other connecting rod 26 to move. The reverse movement of the two connecting rods 26 causes the brake blocks 29 connected at both ends to move away from each other, releasing the clamping and locking of the connecting rod 19. At this time, the connecting rod 19 pops out from the telescopic groove 21 and extends out under the elastic force of the compression spring 25, pushing the lever 14. The brake block 29 resets and clamps the connecting rod 19.

[0040] like Figure 6 As shown, the center of the limiting groove 23 is rotatably connected to the gear 27. There are two racks 28 arranged symmetrically above and below the gear 27. Each rack 28 is fixedly connected to a connecting rod 26. Both racks 28 are meshed with the same gear 27 for transmission. One side of one of the connecting rods 26 is fixedly connected to a pull rod 14, which passes through the door panel 12.

[0041] In a specific implementation, only the connecting posts 19 on both sides of one end of the door panel 12 extend out and are inserted into the hinge holes 18 of the horizontal door frame 11 to form a hinged connection. At this time, the door panel 12 rotates around the connecting posts 19, and the side door frame 10 and the horizontal door frame 11 form a rectangular door frame. At this time, a hinged door is formed between the door panel 12, the two side door frames 10, and the two horizontal door frames 11. The connecting posts 19 at all four corners extend out completely, the horizontal door frame 11 is placed vertically, and the side door frame 10 is placed horizontally, so that the connecting posts 19 are engaged in the sliding grooves 20 of the side door frame 10. At this time, the connecting posts 19 on both sides of the door panel 12 slide along the sliding grooves 20 of the side door frame 10 to realize horizontal sliding door opening. The number of horizontal door frames 11 can be increased according to the length of the door panel to adapt to different door opening widths. The door panel 12 can slide horizontally between the sliding grooves 20 of the upper and lower side door frames 10 through the connecting posts 19 to form a sliding door.

[0042] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
