Description

Technical Field

[0001] The invention relates to the technical field of wooden door manufacturing, in particular to an anti-collision wood-plastic door. Background Art

[0002] Wood-plastic doors are made by mixing ultra-fine wood powder with polymer resin through a molding process. They have the excellent properties of both wood and plastic, and the products produced achieve a true wood-like effect.

[0003] In daily life, WPC doors are cheaper and more beautiful in appearance than solid wood doors and metal doors, and are often used in interior decoration of residential houses. However, compared with solid wood doors and metal doors, they are more fragile because they are made of synthetic wood. In life, some careless situations, such as children playing and running in the house, or strong winds passing through the house during ventilation, will cause the door body to open or close suddenly. The opening or closing of the door body will cause a sudden collision with the door frame or wall, which may easily cause bumps on the WPC door or wall, resulting in damage to the door body or wall, thereby affecting its service life or property loss for repair. Even, when the door is suddenly opened when the child is playing and running, the door and the wall will suddenly collide and rebound, which will also cause injury to the child, so the anti-collision setting of the door body is particularly important.

[0004] Among them, adding some anti-collision components on both sides of the door body is the current mainstream setting scheme. For example, an anti-collision door with patent number: 201310627440.5 faces the technical problem that the anti-collision door is provided with soft door stops that occupy a large volume on both sides of the door body. However, in daily use, the door stops occupy a large volume, affecting the use space in the house. At the same time, when children run or elderly people with limited mobility open the door, it causes inconvenience or scratches. Moreover, the door panels used in indoor houses are usually one-way opening structures. Even if door stops are provided on both sides of the door panels, even if they can cushion the door panels when opening, they still cannot achieve cushioning when suddenly closing. Moreover, the soft door stops will cause a larger rebound when they come into contact with the wall. In severe cases, they will cause secondary injuries to the users. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides an anti-collision wood-plastic door to solve the technical problems raised in the above background technology.

[0006] In order to achieve the above object, the present invention provides the following technical solutions: A collision-proof wood-plastic door comprises a door frame and a door panel which can be opened and closed and is arranged in the door frame. Two fixed shafts are arranged on one side of the inner side of the door frame body. A gear is fixedly installed in the middle of the fixed shaft.

[0009] Furthermore, a pop-up hole is horizontally opened in the middle of the rear end surface of the installation bin, and two groups of installation holes 2 are correspondingly opened on the upper and lower end surfaces of the installation bin, and the two groups of installation holes 2 are arranged at intervals. A group of upper and lower corresponding limiting slide rails are also opened between the two groups of installation holes 2 on the upper and lower end surfaces of the installation bin. The limiting slide rails are arranged at an angle, and an anti-collision component placed in the installation bin is installed through the two groups of installation holes 2 and one group of limiting slide rails.

[0010] Furthermore, the anti-collision component includes two mounting shafts, and the two mounting shafts are respectively arranged corresponding to a group of mounting holes. The upper and lower ends of the mounting shafts can be rotatably installed in the corresponding mounting holes two. A half-width gear is arranged in the middle of the mounting shaft, and the half-width gear is meshed with the gear block at the rear end of the rack.

[0011] Furthermore, connecting pieces placed on the mounting shaft are symmetrically arranged on the upper and lower sides of the half-width gear, and the connecting pieces on the two mounting shafts are rotatably connected to a mounting bar at one end away from the half-width gear. A plurality of connecting shafts protrude from the upper and lower ends of the mounting bar, and the mounting bar is connected to the hidden connecting piece through the connecting shaft. A second mounting groove is horizontally opened at the rear end of the mounting bar, and an anti-collision rubber strip is installed through the second mounting groove.

[0012] Furthermore, a mounting plate is protruded from the middle of the rear end of the mounting bar, and limit rods are protruded from both upper and lower ends of the mounting plate, and the limit rods at the upper and lower ends of the mounting plate are slidably arranged in the limit slide rails.

[0013] Furthermore, the installation bin is provided with an opening on one side close to the limiting device, and two fixed columns are provided on the upper and lower sides of one end of the rack in the installation bin close to the limiting device, and two pulleys are provided on each fixed column. The end of the rack provided with the fixed column can pass through the opening on one side of the installation bin.

[0014] Furthermore, the limiting device includes a limiting groove, and limiting strips are provided in the middle of the upper and lower end surfaces of the limiting groove, and both sides of the limiting strip are wavy continuous undulating structures.

[0015] Furthermore, a brake assembly is provided in the door panel, and the brake assembly includes an installation cavity opened at the lower end of the anti-collision mechanism on the lower side of the door panel, a brake rod is provided in the installation cavity, support wings are extended on both sides of the brake rod, and elastic parts are provided at the lower ends of the support wings on both sides, and the bottom of the elastic part is in contact with the bottom of the installation cavity. A brake opening is provided on the lower end surface of the door panel, and the brake opening is conductively connected to the installation cavity, and a brake strip placed in the brake opening is horizontally placed at the lower end of the brake rod, and the lower end of the brake strip has two anti-collision rubber strips.

[0016] The present invention has the following beneficial effects: By setting an integrated rack and chain, the chain is meshed with gear 1. When the door panel is opened, gear 1 pulls the chain inward to drive the rack, and at the same time, the limit device is retracted into the door panel, and the rack pulls the half-width gear to make the installation strip pop out through the pop-up hole. The anti-collision rubber strip on the installation strip contacts the cavity to avoid bumps. Conversely, when the door panel is closed, gear 1 pushes the chain outward and the chain pushes the rack, so that the installation strip is retracted again, reducing the occupied area of ​​the anti-collision mechanism, and at the same time protruding the limit device again, slowing down the closing speed of the door frame.

[0017] By setting up a brake assembly, when the mounting strip pops out through the pop-up hole, the limit rod at the lower end of the limit plate collides with the brake rod and presses it down, and the brake strip at the lower end of the brake rod protrudes from the brake mouth to the external anti-collision strip and contacts the ground to stop the door panel. The friction can also reduce the rebound after the anti-collision mechanism collides with the wall, avoiding secondary injury to the user.

[0018] By setting up pulley 2, when the door panel is closed, pulley 2 contacts the limit bar, which can reduce the impact force when the door panel is closed and provide continuous resistance when the door panel is closed. Moreover, when the user leaves a gap in the door for ventilation, pulley 2 can be kept in the undulating groove of the limit bar with a wavy structure to limit the swing of the door panel.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0024] Example 1: Combine Figure 1-5 , a collision-proof wood-plastic door, comprising a door frame 1 and a door panel 2 that can be opened and closed and is arranged in the door frame 1, two fixed shafts 101 are provided on one side of the inner side of the door frame 1, and a gear 102 is fixedly installed in the middle of the fixed shaft 101, and a limiting device corresponding to the two fixed shafts 101 is provided on the side opposite to the fixed shaft 101 in the door frame 1. The door panel 2 also includes two anti-collision mechanisms, which are respectively arranged on the upper and lower sides of the door panel 2, and the left and right sides of the two anti-collision mechanisms correspond to a fixed shaft 101 and a limiting device respectively. The door panel 2 is axially connected to the two fixed shafts 101 on the inner side of the door frame 1 through the two anti-collision mechanisms.

[0025] As a technical solution of this embodiment, further, combined with Figure 7 The anti-collision mechanism includes a mounting bin 3, which is embedded in the door panel 2. The upper and lower ends of the mounting bin 3 are the same width and length as the door panel 2, and the mounting bin 3 and the door panel 2 are an integrated structure. At the same time, the entire shell of the mounting bin 3 is a metal structure, and the mounting bin 3 provides a harder shell hardness. The mounting bin 3 is adjacent to the fixed shaft 101 at one end and has mounting holes 301 at the upper and lower ends. The mounting bin 3 is axially connected to the fixed shaft 101 through the mounting holes 301. The mounting holes 301 are axially connected to the fixed shaft 101 to provide fixation for the mounting bin 3. A conductive member is fixed between the corresponding mounting holes 301 at the upper and lower ends, and the gear 102 is placed in the mounting bin 3.

[0026] As a technical solution of this embodiment, further, combined with Figure 8The front end surface of the installation chamber 3 is continuously opened with a slot 1 305 in the horizontal direction, and a rack 5 is slidably arranged in the slot 1 305. The rack 5 and the slot 1 305 are set in the same length. Under the equal length structure, a slight movement of the rack 5 to the left and right can achieve different effects brought by the rack 5. The front end of the rack 5 is arranged in a horizontal array with multiple clamping members 504, and the middle of the clamping member 504 can be rotatably provided with a pulley 1. The rear end of the rack 5 is multiple clamping members 504. They are all clamped and arranged in the slot 1 305, and the pulley 1 is adjacent to the bottom of the slot 1 305. The friction between the pulley 1 and the bottom of the slot 1 305 is reduced to make the rack 5 smoother during the left and right movement and avoid jamming. A chain 501 is extended at one end of the rack 5 close to the fixed shaft 101, and the chain 501 and the inner side of the rack 5 are both arranged in a horizontal array with tooth blocks 502. The chain 501 is meshed with the gear 102 through the inner tooth block 502, and the chain 501 is arranged around the gear 102, and the outer end of the chain 501 is fixedly connected to the gear 102. Since the chain 501 is easier to change its direction than the rack 5, the chain 501 is used at one end connected to the gear 102 and one end of the chain 501 is fixed on the gear 102. When the door panel 2 rotates, the gear 102 is a fixed structure and does not rotate. During the rotation of the door panel 2, the door panel 2 opens and changes the angle between the door panel 2 and the door frame 1, and the rack 5 changes accordingly, thereby realizing the pulling of the gear 102 and the rack 5, so that it is retracted inward into the installation compartment 3. On the contrary, when the door panel 2 is closed and restored, the door panel 2 is flush with the door frame 1 and the rack 5 state is restored. The rack 5 is pushed out again and engages with the limit device.

[0027] As a technical solution of this embodiment, further, combined with Figure 7 A pop-up hole 304 is horizontally opened in the middle of the rear end surface of the mounting bin 3, and two groups of mounting holes 302 are correspondingly opened on the upper and lower end surfaces of the mounting bin 3. The two groups of mounting holes 302 are arranged at intervals, and a group of upper and lower corresponding limiting slide rails 303 are also opened between the two groups of mounting holes 302 on the upper and lower end surfaces of the mounting bin 3. The limiting slide rail 303 is tilted, and the tilt direction of the slide rail is the direction of the mounting bar 602 during work. The anti-collision component placed in the mounting bin 3 is installed through the two groups of mounting holes 302 and a group of limiting slide rails 303.

[0028] As a technical solution of this embodiment, further, combined with Figure 8The anti-collision component includes two mounting shafts 601, and the two mounting shafts 601 are respectively arranged corresponding to a group of mounting holes 302. The upper and lower ends of the mounting shafts 601 can be rotatably installed in the corresponding mounting holes 302. A half-width gear 6 is provided in the middle of the mounting shaft 601. The half-width gear 6 is meshed with the rear end gear block 502 of the rack 5. The upper and lower sides of the half-width gear 6 are symmetrically provided with connecting pieces 604 placed on the mounting shaft 601. The connecting pieces 604 on the two mounting shafts 601 are rotatably connected to the mounting bar 602 at one end away from the half-width gear 6. A plurality of connecting shafts protrude from the upper and lower ends of the mounting bar 602. The mounting bar 602 is connected to the connecting piece 604 through the connecting shaft. A second mounting groove is horizontally opened at the rear end of the mounting strip 602, and an anti-collision rubber strip 603 is installed through the second mounting groove. A mounting plate 605 protrudes from the middle of the rear end of the mounting strip 602, and limit rods 606 protrude from the upper and lower ends of the mounting plate 605. The limit rods 606 at the upper and lower ends of the mounting plate 605 are slidably set in the limit slide rail 303. When the door panel 2 is hit, the rack 5 slides and drives the half-width gear 6 to rotate. The rotation of the half-width gear 6 causes the mounting strip 602 to slide and pop out in the limit slide rail 303 through the limit rod 606. The anti-collision rubber strip 603 contacts the impact object to further buffer the impact force. At the same time, the design of the half-width gear 6 can prevent the mounting strip 602 from excessive rotation, ensuring that it plays an anti-collision role in the appropriate position.

[0029] As a technical solution of this embodiment, the mounting compartment 3 is further provided with an opening on one side near the stopper, and fixing posts are provided on the upper and lower sides of one end of the rack 5 near the stopper. A second pulley 503 is mounted on the fixing posts, and this end of the rack 5 can extend from the opening of the mounting compartment 3. The second pulley 503 can reduce the friction between the door panel 2 and the stopper. When the door panel 2 rotates and approaches the stopper, the extended portion of the rack 5 engages with the stopper, and under the action of the second pulley 503, the rotation of the door panel 2 is made smoother, and the impact force when the door panel 2 is closed can be further cushioned.

[0030] As a technical solution of this embodiment, the limiting device further comprises a limiting groove, wherein a wavy limiting strip 4 is provided in the middle of the upper and lower end surfaces of the limiting groove. The wavy limiting strip 4 cooperates with the fixed column and the second pulley 503 extending from the portion of the rack 5. When the door panel 2 rotates to the extreme position, the wavy structure further cushions the impact force of the door panel 2, while precisely limiting the position of the door panel 2, preventing the door panel 2 from excessive rotation or shaking due to inertia.

[0031] As a technical solution of this embodiment, further, combined with Figure 9The door panel 2 also includes a brake assembly, which is installed in the mounting cavity 7 at the lower end of the anti-collision mechanism on the lower side of the door panel 2. The brake assembly includes a brake rod 8, with support wings 801 on both sides. The lower ends of the support wings 801 are connected to elastic members 802, and the bottom of the elastic member 802 contacts the bottom of the mounting cavity 7. The lower end surface of the door panel 2 is provided with a brake opening 701 that communicates with the mounting cavity 7. A brake strip 803 at the lower end of the brake rod 8 is placed in the brake opening 701, and an anti-collision rubber strip 804 is provided at the lower end of the brake strip 803. When the door panel 2 is subjected to a large impact force, the mounting strip 602 pops out, and the limit rod 606 at the lower end of the mounting plate 605 slides to the position of the brake rod 8, contacts the brake rod 8 and pushes it downward, the brake rod 8 moves downward, and the brake strip 803 extends out of the brake opening 701 and contacts the ground. The anti-collision rubber strip 804 increases the friction with the ground, causing the door panel 2 to stop moving quickly, effectively preventing the door panel 2 from moving excessively or rebounding due to impact.

[0032] Example 2: In daily life, WPC doors are cheaper and more beautiful in appearance than solid wood doors and metal doors, and are often used in interior decoration of residential houses. However, compared with solid wood doors and metal doors, WPC doors are more fragile because they are made of synthetic wood. In life, in some careless situations, such as when children are playing and running in the house, or when strong winds pass through during ventilation of the house, the door body may be suddenly opened or closed. The opening or closing of the door body may cause a sudden collision with the door frame 1 or the wall, which may easily cause bumps on the WPC door or the wall, resulting in damage to the door body or the wall, thereby affecting its service life or causing property loss for repair. Even, when the door is suddenly opened when the child is playing and running, the door and the wall may suddenly collide and rebound, which may also cause injury to the child. Therefore, the anti-collision WPC door can be provided.

[0033] Combine Figure 1When the user pushes hard to open the door panel 2, the door panel 2 rotates inward, and the door panel 2 is fixed in the door frame 1 by the fixed shaft 101. The door panel 2 opens 90 degrees with the fixed shaft 101 as the axis. During the opening process of the door panel 2, one end of the chain 501 in the mounting chamber 3 embedded in the door panel 2 is fixed to the gear 102 of the fixed shaft 101. During the rotation of the door panel 2, the gear 102 is a fixed structure and does not rotate. During the rotation process of the door panel 2, one end of the chain 501 is fixed to the gear 102, the door panel 2 opens, and the angle between the door panel 2 and the door frame 1 is changed, and the rack 5 changes accordingly, thereby realizing the pulling of the rack 5 by the gear 102, so that it is retracted inward into the mounting chamber 3. In the process of the rack 5 retracting the end provided with the pulley 2 503 into the mounting chamber 3, the rack 5 is pulled, and the rack 5 passes through the inner The tooth block 502 set on the side is engaged with the half-width gear 6, thereby driving the half-width gear 6 to rotate. During the rotation of the half-width gear 6, the mounting bar 602 folded in the mounting compartment 3 is ejected from the outside of the mounting compartment 3 through the pop-up hole 304, and contacts the impacted wall through the anti-collision rubber strip 1 603 installed on its inner side to reduce vibration. During the pop-up process of the mounting bar 602, the lower end limit rod 606 of the mounting plate 605 at the rear end of the mounting bar 602 moves along the path of the limit slide rail 303. When the limit rod 606 slides to the position of the brake rod 8, the limit rod 606 contacts the brake rod 8 and pushes the brake rod 8 downward. The brake rod 8 moves downward, and the brake bar 803 extends out of the brake mouth 701 and contacts the ground. The anti-collision rubber strip 2 804 increases the friction with the ground, so that the door panel 2 stops moving quickly, effectively preventing the door panel 2 from excessive movement or rebound due to impact.

[0034] On the contrary, when the door panel 2 is closed and restored, the door panel 2 is flush with the door frame 1 and the rack 5 state is restored. The gear 1 102 pushes the rack 5 outward. During the pushing process, the rack 5 is meshed with the half-width gear 6 through the inner gear block 502. The mounting bar 602 is retracted into the mounting bin 3 along the path of the limiting slide rail 303 under the rotation of the half-width gear 6. At the same time, one end of the rack 5 provided with the pulley 2 503 extends through the end of the opening of the mounting bin 3. The pulley 2 503 contacts the limiting device. The limiting device is composed of a limiting groove, and a wavy limiting bar 4 is provided in the middle of the upper and lower end surfaces of the limiting groove. The wavy limit strip 4 can cooperate with the fixed column of the protruding part of the rack 5 and the pulley 2 503. When the door panel 2 rotates to the extreme position, the wavy structure further cushions the impact force of the door panel 2, and at the same time, the position of the door panel 2 is accurately limited. Because it is wavy and has more wavy grooves, when the door gap is opened for ventilation in daily life, the pulley 2 503 can be turned to limit the position of the door panel 2 in any gear of the limit strip 4.

[0035] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
