Description

Technical Field

[0001] The invention relates to a door for home decoration, in particular to a stainless steel door. Background Art

[0002] Many families like to use wooden doors as interior doors when decorating their homes, but they often find out after installation that wooden doors have a fatal drawback: they are prone to cracking when heated and deforming when exposed to moisture. With the upgrading of decoration needs, both home decoration and engineering decoration are pursuing high-quality, high-grade and differentiated building materials. Therefore, stainless steel interior doors have gradually become a new choice to replace ordinary solid wood doors and aluminum alloy doors in the field of high-end decoration.

[0003] The existing stainless steel doors still use the hardware accessories of traditional solid wood doors, such as door locks, etc. In the high-end home improvement market, the door has been integrated with the wall, and the abrupt door lock mechanism not only affects the appearance, but also is inconvenient to use. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a stainless steel door to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The solution of the present invention to its technical problem is: a stainless steel door, comprising a door leaf and a door frame, the door leaf and the door frame are hinged by hinges, the door leaf comprises a frame, a first panel and a second panel, the first panel and the second panel are both stainless steel plates, a through hole is provided on the side of the first panel away from the hinge, a pressing block is provided in the through hole, the outer surface of the pressing block is flush with the plate surface of the first panel, the pressing block is connected to the frame for front and rear sliding, a locking pin is provided on the top of the frame, the locking pin is connected to the frame for up and down sliding, a lock seat matching the locking pin is provided in the door frame, and a transmission mechanism is also provided in the frame, and the transmission mechanism is configured as follows: when the pressing block is pushed backward with force, the locking pin moves downward and separates from the lock seat.

[0006] The beneficial effects of the present invention are as follows: the present invention achieves locking of the door leaf and the door frame by arranging a lock pin at the top of the door leaf, thereby eliminating the traditional door lock mechanism on the side of the door leaf, thereby making the side of the door leaf neater and the product more beautiful; in addition, the lock pin is unlocked by utilizing the pressing block on the first panel, and the unlocking action and the door opening action are connected together in one go. When opening the door, the user only needs to operate the pressing block with force to simultaneously unlock and push the door open. Since the surface of the pressing block is basically flush with the first panel, the pressing block and the first panel are basically integrated with each other when not in operation, and the appearance of the entire door leaf is neater.

[0007] As a further improvement of the above technical solution, a handle is provided on the outside of the second panel, and the transmission mechanism includes a main shaft, the front end of the main shaft is connected to the pressing block, and the rear end of the main shaft passes through the second panel and is connected to the handle. A handle is provided on the second panel, and the door can be opened from the inside by the handle.

[0008] As a further improvement of the above technical solution, the transmission mechanism includes a base, the base is fixedly connected to the frame, and the main shaft is slidably connected to the base.

[0009] As a further improvement of the above technical solution, the transmission mechanism further includes a connecting rod, the upper end of the connecting rod is connected to the locking pin, the lower end of the connecting rod is provided with a first wedge block, the main shaft is provided with a second wedge block, and the first wedge block and the second wedge block abut against each other. By using the two abutting wedge blocks, the movement on the main shaft can be converted into the sliding of the connecting rod, thereby realizing the unlocking of the locking pin.

[0010] As a further improvement of the above technical solution, a guide groove is provided on the frame, a guide block is provided on the side of the connecting rod, and the guide block is connected to the guide groove. By adding the guide block and the guide groove, the movement of the connecting rod can be made more stable and smooth.

[0011] As a further improvement of the above technical solution, a return spring is further provided outside the main shaft, and one end of the return spring abuts against the base. The return spring provides a restoring force to the main shaft and provides damping when pressing to unlock, thereby improving the feel of opening the door.

[0012] As a further improvement of the above technical solution, the pressing block is sleeved with the main shaft, the handle is fixedly connected to the main shaft, a locking block is fixedly provided on the main shaft, a stop wall is provided on the base, and a through slot corresponding to the locking block is provided on the stop wall. When a person located on the inside of the door rotates the handle, the locking block is driven to rotate. When the locking block rotates to a position so that the locking block is offset from the through slot, the main shaft cannot move, and the lock pin cannot be unlocked. When you want to unlock, you only need to rotate the handle so that the locking block can correspond to the through slot. When you pull the handle hard or press the pressing block hard, the main shaft can move relatively, thereby unlocking the lock pin.

[0013] As a further improvement of the above technical solution, the upper end of the lock pin is provided with a guide slope, and one side of the door frame is provided with a guide slope, and the guide slope corresponds to the guide slope.

[0024] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. The preferred embodiments of the present invention are shown in the drawings. The purpose of the drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0025] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] In the description of the present invention, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0027] In the description of the present invention, unless otherwise clearly defined, the terms such as setting, installing, connecting, etc. should be understood in a broad sense, and the technical personnel in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution. At the same time, the various technical features in the invention can be combined interchangeably without conflicting with each other.

[0028] As people are pursuing a better life, indoor environmental pollution has been bothering us, especially furniture pollution, which has attracted more attention. Traditional furniture cabinets are generally made of wood products such as density boards, particle boards or solid wood, and wood products generally have excessive formaldehyde, which undoubtedly causes great harm to people who live indoors for a long time and seriously affects people's health. For this reason, the structure of stainless steel wall panels has appeared in the prior art. By using stainless steel panels as wall panels, not only the wall panels are more environmentally friendly and healthy, but also the service life of stainless steel panels is longer.

[0029] In the wall, there is usually a door opening, and a door is installed on the door opening. In the prior art, since door handles are installed on the doors, the doors and wall panels are not coordinated. In some home decorations, in order to coordinate the doors and wall panels, the door lock mechanism is cancelled. However, without the door lock mechanism, the door leaf will not be closed tightly, and without the door lock, it will also bring inconvenience to use.

[0030] To this end, the present invention proposes a stainless steel door that can better echo the wall panel. Figure 1 to Figure 5 The stainless steel door comprises a door frame 100 and a door leaf 200 , wherein the door frame 100 is used for being fixedly installed on a door opening, and the door leaf 200 and the door frame 100 are hingedly connected via a hinge 300 .

[0031] For example, in this embodiment, the hinge 300 is installed on the left side, and the door leaf 200 of this embodiment is opened inward (or backward). In the closed state, the surface of the door leaf 200 and the door frame 100 are flush.

[0032] The door frame 100 includes a profile body 110, and the profile body 110 includes a mounting edge 111 and a front end face 112. The front end face 112 is provided with a slot 113, and the slot 113 is used for installing and fixing the wall panel. During installation, the mounting edge 111 is fixed to the wall by expansion bolts or self-tapping screws, and a second slot 114 is provided on the outer side of the mounting edge 111. Similarly, a wall panel is also fixedly installed on the second slot 114. After the profile body 110 is fixed to the wall, the wall panel is embedded in the second slot 114 to cover the mounting bolts, which is not only more beautiful, but also by embedding and installing the wall panel on both sides of the profile body 110, the wall panel is covered with the wall panel, thereby eliminating the need for painting the wall and improving the decoration efficiency.

[0033] In addition, in order to ensure better sealing between the door leaf 200 and the door frame 100, a step surface 115 is provided on the front side of the profile body 110; when closing the door, the edge of the door leaf 200 abuts against the step surface 115, thereby achieving a tight closing effect. Furthermore, by providing a sealing strip on the step surface 115, a better sealing and silent effect can be achieved.

[0034] The door leaf 200 includes a frame 230. The frame 230 can be formed in various ways, such as by welding a plurality of frame profiles, or by assembling a plurality of frame profiles through hardware such as angle brackets. In addition, in order to play a better supporting role, a filling profile can also be provided in the frame 230. By assembling the filling profile with the frame profile, the installation efficiency and the flexibility of the installation can be improved. The outer side of the frame 230 is covered with two stainless steel panels, namely the first panel 210 and the second panel 220. The first panel 210 is located on the outer side of the frame 230, and the second panel 220 is installed on the inner side of the frame 230. The first panel 210 and the second panel 220 can wrap up a total of six end faces of the frame 230, namely, the upper and lower, left and right, and front and back. Therefore, the first panel 210 and the second panel 220 are both formed by bending.

[0035] Specifically, the first panel 210 includes a first surface 211, and a first bent edge 212 is provided around the first surface 211. The head end of the first bent edge 212 is connected to the first surface 211, and a first clamping edge 213 is also provided at the end of the first bent edge 212; the second panel 220 includes a second surface 221, and a second bent edge 222 is provided around the second surface 221. The head end of the second bent edge 222 is connected to the second surface 221, and a second clamping edge 223 is also provided at the end of the second bent edge 222, and the second clamping edge 223 and the first clamping edge 221 are tightly abutted against each other.

[0036] In addition, in order to cooperate with the step surface 115 and improve the sealing effect of the door leaf, the length of the second panel 220 is greater than the length of the first panel 210, so that a second step surface is formed between the first bent edge 212 and the second bent edge 222, and the second step surface can cooperate with the step surface 115. Thus, two step surfaces that cooperate with each other can be used between the door frame 100 and the door leaf 200, so that when the door is closed, there is no light gap, and the sealing effect is better.

[0037] In order to make the door leaf 200 reliably closed in the door frame 100, a hidden door lock mechanism 400 is provided on the right side of the door leaf 200. Specifically, the door lock mechanism 400 includes a pressing block 410, which is installed on the outer side of the door leaf 200 (i.e., the first panel 210). The pressing block 410 can be set to be about the size of a human palm, and the pressing block 410 is movably connected to the door leaf 200, and the pressing block 410 can move relative to the door leaf 200 along the front and rear direction. Under normal circumstances, the outer surface of the pressing block 410 is substantially flush with the first surface 211 of the first panel 210, that is, the pressing block 410 does not protrude from the outer surface of the door leaf 200. In order to ensure rigidity, the pressing block 410 has a certain thickness, and the thickness of the pressing block 410 is also greater than the plate thickness of the first panel 210, so that the pressing block 410 can be relatively embedded in the door leaf 200 as a whole. Therefore, in order to ensure reliable movement of the pressing block 410, the pressing block 410 is slidably connected to the frame 230 of the door leaf 200. A through hole is provided on the first surface 211, and the size and shape of the through hole match the size and shape of the pressing block 410. It can be understood that, under the premise of ensuring that the pressing block 410 can move smoothly, the smaller the gap between the pressing block 410 and the through hole, the better, so that the consistency of the outer surface of the door leaf 200 can be better ensured.

[0038] In addition, the door lock mechanism 400 also includes a lock pin 420 and a transmission mechanism 430. The lock pin 420 is slidably arranged on the upper end surface of the right side of the door leaf 200. Correspondingly, a lock seat 120 cooperating with the lock pin 420 is provided on the upper part of the door frame 100, and the lock seat 120 is nested and installed in the profile body 110. The transmission mechanism 430 is used to realize the motion transmission between the pressing block 410 and the lock pin 420. It can be understood that there can be many ways of the transmission mechanism 430. As mentioned above, the pressing block 410 moves along the front-to-back direction relative to the door leaf 200, and the lock pin 420 moves up and down relative to the door leaf 200, and the transmission mechanism only needs to realize that when the pressing block 410 moves backward, it can drive the lock pin 420 to move downward. It is understandable that the door leaf 200 is a stainless steel door, which is different from a traditional solid wood door. It includes a frame 230, and the frame 230 has a larger cavity, thus creating great convenience for the installation of the transmission mechanism 430.

[0039] It can be seen that in this solution, by using the pressing block 410 that can be relatively hidden in the door leaf 200, the lock pin 420 located above the door leaf 200 is controlled, so as to achieve the locking and unlocking of the door leaf 200 and the door frame 100. Compared with the traditional method of setting a lock tongue on the side of the door leaf 200 and setting a matching lock seat on the side of the door frame 100, the lock pin and the lock seat are set at the top of the door leaf and the door frame, so that the side of the door leaf is more neat and beautiful, and the appearance consistency of the product is better. Since the door leaf 200 is generally more than 2.3 meters, the user cannot see the lock pin 410 and the lock seat 120 under normal use. At the same time, since the pressing block 410 is relatively hidden and set on the outer surface of the door leaf 200, the gap between the pressing block 410 and the door leaf 200 can be very small, so that at first glance, the structure of the pressing block 410 cannot be seen, so the consistency between the door leaf 200 and the door lock mechanism 400 is better, and the product is more beautiful. In addition, as mentioned above, in this embodiment, the door leaf 200 is opened inward (toward the rear), and the unlocking action of the pressing block 410 is also moved backward. Therefore, the unlocking action of the door lock mechanism 410 and the door opening action can be completed in one go, which improves the user experience. In traditional door locks, when it is necessary to unlock and open the door, it is often necessary to twist the handle by hand first, and then push the door backward with force while keeping the twist. Therefore, the door opening action includes two steps, but after adopting the door lock structure of this embodiment, only one step is needed, that is, pushing the pressing block 410 backward with force, to achieve the release of the door lock and the opening of the door leaf, making the operation easier.

[0040] In the above embodiment, it is introduced how to realize opening the door leaf from the outside of the present invention, and the following will further introduce how to realize opening the door leaf from the inside.

[0041] As mentioned above, in this embodiment, the door leaf 200 is opened inwards, and because the door leaf 200 and the door frame 100 are matched through the step surface, the door leaf 200 can only be opened inwards. That is, if you want to open the door leaf from the inside, you need to pull the door leaf inwards. Therefore, it is necessary to set a handle 440 on the second panel 220 of the door leaf 200, and the handle 440 can also be connected to the transmission mechanism 430 and is transmission-connected to the lock pin 420. When the handle 440 is pulled backwards with force, the door can be unlocked and the door leaf can be opened, which is also a smooth action, improving the convenience of operation.

[0042] Specifically, the transmission mechanism 430 may be provided with a main shaft 431, which passes through the door leaf 200 along the front-to-back direction and is sleeved with the frame 230, that is, the main shaft 431 can move forward and backward relative to the frame 230, and the pressing block 410 is installed at the front end of the main shaft 431, and the handle 440 is installed at the rear end of the main shaft 431. The main shaft 431 can realize the linkage of the pressing block 410 and the handle 440, that is, when the pressing block 410 is forced to move backward, the handle 440 is synchronously driven to move backward through the main shaft 431; similarly, when the handle 440 is pulled backward by force, the pressing block 410 also moves backward synchronously. As mentioned above, when the pressing block 410 moves backward, it can drive the lock pin 420 to move downward, thereby realizing the unlocking of the door leaf 200 and the door frame 100.

[0043] In order to facilitate the installation of the main shaft 431 and the frame 230, the transmission mechanism 430 also includes a base 432, and a guide structure such as a guide hole or a guide groove is provided in the base 432. The main shaft 431 is connected to the base 432 by sliding forward and backward through the above-mentioned guide structure, and the base 432 is fixedly installed in the frame 230. Further, in order to improve the smoothness of the front and back movement of the main shaft 431, the material of the base 432 can be made of wear-resistant material, and grease can be provided in the guide hole to improve the smoothness of the main shaft 431 when moving forward and backward.

[0044] As mentioned above, the main function of the transmission mechanism 430 is to convert the forward and backward movement of the pressing block 410 (or the main shaft 431) into the upward and downward movement of the locking pin 420. In order to achieve the above function, the transmission mechanism 430 can adopt the following scheme:

[0045] See also Figure 5 As a further preferred embodiment, the transmission mechanism 430 also includes a connecting rod 433, the upper end of the connecting rod 433 is connected to the locking pin 420, the lower end of the connecting rod 433 is provided with a first wedge block 434, the main shaft 431 is provided with a second wedge block 435, and the first wedge block 434 and the second wedge block 435 are in contact with each other.

[0046] The connecting rod 433 extends in the up-down direction, and the connecting rod 433 has good rigidity and can play a role in force transmission. As mentioned above, since the locking pin 420 is installed at the top of the door leaf 200, and the pressing block 410 is generally installed in the middle of the door leaf 200, the transmission between the two requires a connecting rod 433 to achieve transmission. Therefore, the length of the connecting rod 433 is generally not less than 1 meter. In order to ensure the rigidity of the connecting rod 433, the connecting rod 433 can be a hollow tube body, and the connecting rod 433 is provided with ridges around it, and the frame 230 is provided with a guide groove extending in the up-down direction. The ridge is connected with the guide groove. In addition to strengthening the rigidity of the connecting rod 433, the ridge also plays a guiding role by cooperating with the guide groove, that is, the ridge can also be used as a guide block.

[0047] In this embodiment, two wedge-shaped blocks abutting against each other are used to change the direction of force transmission. Figure 5 , both wedge blocks include an inclined surface, which is gradually inclined downward along the front-back direction. When the main shaft 433 drives the second wedge block 435 to move backward, the first wedge block 434 gradually moves downward under the action of its own gravity under the cooperation of the inclined surface. Since the first wedge block 434 and the lock pin 420 are connected by a rigid connecting rod 433, when the first wedge block 434 moves downward, the lock pin 420 also moves downward synchronously, thereby unlocking the door leaf 200. In this embodiment, the wedge block with an inclined surface is used as the main component for changing the direction of the transmission force, which can simplify the transmission mechanism 430, reduce mechanical accessories, and improve installation efficiency. At the same time, the wedge block can be made of wear-resistant polymer materials, thereby improving the service life of the wedge block.

[0048] In addition, in order to improve the self-locking ability of the lock pin 420, the transmission mechanism 430 further includes a return spring 436, which is installed in the base 432, one end of which abuts against the inner wall of the base 432, and the other end abuts against the second wedge block 435. Under normal circumstances, the spring force provided by the return spring 436 makes the second wedge block 435 tend to move forward, thereby preventing the first wedge block 434 from moving downward, thereby preventing the door leaf 200 from being accidentally unlocked. When the door needs to be unlocked, the main shaft 431 and the second wedge block 435 are driven to move backward to overcome the elastic force of the return spring 436 by pushing the pressing block 410 or pulling the handle 440, thereby driving the first wedge block 434, the connecting rod 433 and the lock pin 420 to move downward, so that the door leaf 200 is unlocked.

[0049] By adjusting the return spring 446 to provide a suitable spring force, the pressing block 410 can have a good damping feeling when unlocking, improving the feel of the operation. At the same time, the suitable spring force can also play a good self-locking role. In order to adjust the self-locking force, it can also be achieved by setting the inclination angle of the inclined surface.

[0050] In some usage scenarios, if the people inside do not want people outside to enter, they need to lock the door from the inside to prevent people outside from entering. As mentioned above, in this embodiment, the handle 440 and the pressing block 410 are synchronously linked through the main shaft 431, that is, when unlocking, the pressing block 410 and the handle 440 will move synchronously. In order to achieve the anti-locking effect, it is necessary to perform the action indoors to prevent people outside from operating the pressing block 410 to unlock the lock pin 420.

[0051] In order to achieve the above functions, the transmission mechanism 430 is optimized in this embodiment. Figure 5 As a further preferred embodiment, the main shaft 431 is cylindrical, the pressing block 410 is sleeved with the front end of the main shaft 431, and the second wedge block 435 is also sleeved with the main shaft 431; that is, the main shaft 431 can rotate freely around the axis of the main shaft 431 relative to the pressing block 410, the second wedge block 435 and the base 432, and the handle 440 is fixed to the rear end of the main shaft 431. Since the handle 440 is fixed to the main shaft 431, the handle 440 can also rotate relative to the base 432; in addition, a locking block 437 is fixedly arranged on the outer peripheral wall of the main shaft 431, and a stop wall is provided on the base 432, and a through groove penetrating from front to back is provided on the stop wall, and the locking block 437 corresponds to the through groove. Specifically, the locking block 437 and the passing slot are configured as follows: when the locking block 437 as a whole corresponds to the passing slot, the locking block 437 can pass through the passing slot along the front-to-back direction; when the locking block 437 is rotated, the locking block 437 will be held by the stop wall and cannot move forward or backward.

[0052] Through the above structural optimization, the door lock mechanism 400 also has an anti-locking function. The pressing block 410 can only move along the front-to-back direction under the limitation of the through hole of the first panel 210; and the handle 440 is connected to the frame 230 through the main shaft 431. Therefore, in addition to moving along the front-to-back direction, the handle 440 can also be rotated around the axis of the main shaft 431. When the handle 440 rotates, it can synchronously drive the locking block 437 on the main shaft 431 to rotate. The handle 440 can be set to two positions. When the handle 440 is in the first position, the locking block 437 can correspond to When the handle 440 is in the second position, the locking block 437 is changed in position so that it no longer corresponds to the through slot. At this time, if the outdoor personnel push the pressing block 410 with force, the locking block 437 abuts against the stop wall, and the main shaft 431 cannot move backward, so that the door lock cannot be opened, thereby realizing the anti-locking function of the door leaf on the inside.

[0053] Of course, in order to improve the strength of the reverse locking, the locking block 437 can have multiple pieces, for example, 3-4 locking blocks 437 can be arranged at equal intervals on the outer periphery of the main shaft 431, and of course, the corresponding through slots also correspond to the locking blocks 437 one by one. In addition, in order to facilitate the personnel in the room to intuitively see whether the door lock is reverse locked, an indicator block can be arranged on the handle 440 and the second panel 220. Through the indicator block, it is known whether the handle 440 is in the first position or the second position. At the same time, further, a marble can be arranged on the base 432, and two arc-shaped pits can be arranged on the outer periphery of the main shaft 431, the pits corresponding to the positions of the marbles, and the two pits correspond to the two positions of the handle respectively. Since the marble has a certain elasticity, when the marble corresponds to the pit, it can play a certain limiting role, and the marble is used to provide a certain damping to the rotation of the handle 440, thereby improving the operating feel of the handle 440. For example, when the handle 440 is located at the first position or the second position, the marble is just stuck in the pit, and the handle cannot be easily rotated. When the handle 440 needs to be rotated, the marble escapes from the pit and abuts against the outer end surface of the main shaft 431 until the marble enters another pit, at which time the marble enters the pit again, thereby providing resistance to the rotation of the handle. People can use it more conveniently by changing the damping of the operating handle or whether the handle is rotated in place.

[0054] In some other embodiments, a second door lock mechanism may be provided on one side of the room, and the door leaf may be locked reversely by the second door lock mechanism.

[0055] In this embodiment, the transmission mechanism 430 mainly utilizes the cooperation of two wedge blocks to realize the motion transmission between the main shaft and the connecting rod. In other embodiments, the force transmission can also be realized by means of gear racks. For example, the transmission mechanism 430 can include a first rack, a second rack, and a transmission gear. The forward and backward movement of the main shaft is converted into the linear motion of the first rack, and the first rack transmits the motion to the second rack through the transmission gear, and the second rack drives the connecting rod to move. In addition to gear racks, the transmission mechanism can also be a worm gear, a crank connecting rod mechanism, etc.

[0056] As mentioned above, since the transmission mechanism 430 includes a return spring 436, in the absence of external force, the elastic force provided by the return spring 436 will cause the lock pin 420 to automatically push upward. That is, in the absence of external force, when the door leaf 200 is not in a closed state, the lock pin 420 will protrude from the top of the door leaf 200. At this time, if the door leaf 200 needs to be closed, the protruding lock pin 420 will hit the door frame 100, making it difficult to close the door leaf 200. In order to overcome the above-mentioned shortcomings, see Figure 4 As a further preferred embodiment, the upper end of the lock pin 420 is provided with a guide slope, and the inner side of the door frame 100 is provided with a guide slope, and the guide slope corresponds to the guide slope. The guide slope and the guide slope can facilitate the lock pin 420 to automatically enter the lock seat 120. When closing the door, the guide slope first contacts the guide slope of the door frame 100, and then the guide slope forces the guide slope to move downward, that is, the guide slope forces the lock pin 420 to move downward, so that the lock pin 420 avoids the door frame 100. When the lock pin 420 moves to the position corresponding to the lock seat 120, the lock pin 420 is pushed upward again under the action of the reset spring 436, thereby achieving the locking of the door leaf 200. In addition, the guide slope also serves to facilitate the lock pin 420 to enter the lock seat 120.

[0057] Furthermore, in order to improve the privacy of the room, the hinge 300 is configured to drive the door leaf 200 to close automatically, that is, in the absence of external force, the door leaf 200 will automatically close under the action of the hinge 300. In order to achieve the above function, a torsion spring can be set in the hinge 300, and the torsion spring is used to provide the door leaf 200 with a force to lock the door. In addition, by setting a first magnet block on the side of the door leaf 200, and setting a second magnet block corresponding to the first magnet block in the door frame 100, the door leaf 200 and the door frame can be better self-locked by using two magnets that attract each other. When the door leaf 200 is opened at a large angle, the two magnets are far away, the force is small, but the force of the torsion spring is large; and when the door leaf 200 is opened at a small angle, the two magnets are close, the force is large, and the force of the torsion spring is small. By adaptively adjusting the force of automatic door closing by the torsion of the torsion spring and the attraction of the magnet, the automatic door closing function of the door leaf 200 can be better achieved.

[0058] For ease of operation, traditional door handles are installed at a height of about 110 cm, but such an installation height is within the reach of many 2-3 year old children. As a further improvement of the above technical solution, the installation height range of the push block 410 from the ground is 130 cm to 150 cm. By setting the push block higher than the height of a general door lock handle, it can effectively prevent children from accidentally opening the door. Moreover, by adjusting the installation position of the push block 410 to a higher position, the length of the connecting rod 433 can be relatively shortened, thereby improving the smoothness of the movement. In addition, the push block 410 is set at a higher position, which can also facilitate the overall decoration of the door leaf and improve the appearance of the door leaf 200.
