Description

Technical Field

[0001] The invention relates to the technical field of wooden doors, in particular to a durable and strong soundproof wooden door. Background Art

[0002] Wooden doors have the functions of space separation, security protection, privacy protection, decoration and environmental regulation. They can divide indoor and outdoor areas and different functional areas, provide anti-theft and security barrier functions, block external vision and sound to protect privacy, and regulate the indoor environment through thermal insulation and sound insulation.

[0003] Wooden doors usually have gaps at the upper and lower ends so that the wooden door panels can still be opened and closed normally after expansion and deformation. However, with this technology, indoor heating and cooling air will escape from these gaps in winter and summer, causing energy loss. At the same time, the gaps will also make the sound insulation effect of the wooden door unsatisfactory. If the gap between the wooden door and the ground is reduced, the wooden door may be unable to be closed when it is deformed. In response to the above problems, the prior art provides a solution. For example, patent application number CN202320448783.4 provides a soundproof sealed wooden door. The patent provides a solution including a frame, a front panel and a rear panel, which are respectively installed in the frame, a cavity is provided between the front panel and the rear panel, noise reduction mechanisms are provided in the front panel and the rear panel, and a sealing mechanism includes teeth installed in the cavity. Wheel, racks meshing with both sides of the gear, and a sealing plate arranged on the end of the rack, the sealing plate enters or exits the upper and lower sides of the wooden door through the rack, and a noise reduction mechanism is arranged in the wooden door body, which has a good sound insulation effect, so that the indoor and outdoor noises can be isolated. When the wooden door body is closed, the gear is rotated, and the gear drives the rack to move the sealing plate outward to the upper and lower ends of the wooden door body to increase the sealing performance. The sealing plate exits the upper and lower sides of the wooden door body, which is beneficial to the opening of the wooden door body. The device is simple to operate, and the wooden door body has good sealing performance and noise reduction effect, and is highly practical. When closing and opening the door, it is necessary to manually rotate the gear to make the sealing plate extend out of the wooden door body. The process is relatively cumbersome. At the same time, there will be a problem that the user will not pay attention and will not rotate the gear in time and directly open and close the wooden door, which will cause damage to the sealing mechanism, thereby affecting the service life of the wooden door. Summary of the invention

[0004] The purpose of the present invention is to provide a durable and strong soundproof wooden door to solve the problem in the prior art that directly opening and closing the wooden door will cause damage to the sealing mechanism, thereby affecting the service life of the wooden door.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A durable and sturdy soundproof wooden door, comprising a wooden door body, hinges, connecting rods, handles, card blocks and sealing pins, wherein one side of the wooden door body is fixed to a door frame by a plurality of hinges, and a lock body is installed in the other side of the wooden door body, and the lock body is connected to the handle by a connecting rod, and the handle is symmetrically arranged at the front and back of the wooden door body, the lock body is connected to a lock tongue, and the lock tongue extends out of the wooden door body, and the lock tongue is slidably connected to the door frame, and an extension component and a retraction component are arranged in the wooden door body, and telescopic grooves are arranged in the upper and lower ends of the wooden door body, and a sealing pin is slidably connected in the telescopic groove, and the lower end surface of the sealing pin is made of a flexible material, and a card block is provided on the end surface of the sealing pin close to the lock body, and the sealing pin is connected to the extension component through the card block, and the extension component drives the sealing pin in the wooden door body to extend through the closing of the hinge, and the recovery component controls the extension component to retract the sealing pin into the wooden door body through the twisting of the handle.

[0007] It is easy to understand that the wooden door body is connected to the door frame through the hinges on the side, and the wooden door body rotates around the axis of the hinge to realize the opening and closing of the door. When the wooden door body is closed, the lock tongue is connected and cooperated with the door frame to fix the wooden door body. When the wooden door needs to be opened, the lock body is unlocked by the key, and the handle is twisted to drive the connecting rod to twist. The rotating connecting rod drives the lock tongue to retract through the lock body, and the lock tongue is separated from the door frame, thereby releasing the fixation of the wooden door body.

[0008] Furthermore, when the wooden door body is closed, in order to allow the wooden door body to open and close normally when it expands and deforms under different ambient temperatures, gaps are reserved at the upper and lower ends of the wooden door body. The existence of the gap reduces the sound insulation effect of the wooden door body. Therefore, expansion grooves are opened at both ends of the wooden door body, and sealing pins are slidably installed in the expansion grooves. When the wooden door body is closed, the sealing pins extend from the wooden door body, and then fill the reserved gaps at the upper and lower ends of the wooden door body. The lower end surface of the sealing pin is made of rubber. The rubber has high elasticity, good flexibility, deformability, wear resistance and certain sound insulation. There may be gaps or inclinations on the ground. Through the deformation of the rubber, it can better fit the ground. The sealing pins fill the gaps at the upper and lower ends of the wooden door body to avoid the existence of the gaps and reduce the sound insulation effect of the wooden door body, thereby improving the sound insulation effect of the wooden door body.

[0009] Furthermore, when the user directly opens and closes the wooden door without paying attention, the sealing pin will be damaged, thus affecting the service life and sound insulation effect of the wooden door. For this reason, when the wooden door is closed, the closing of the hinge drives the extension component, and the driving component pushes the card block to drive the sealing pin to extend out of the wooden door body. When the wooden door body needs to be opened, the handle is twisted, and at the same time, the recovery component uses the twisting of the handle to control the extension component to retract the extended sealing pin into the wooden door body. The extension component and the recovery component use the closing of the hinge and the twisting of the handle to control the extension and recovery of the seal, thereby avoiding the problem of damaging the sealing pin when the user directly opens and closes the wooden door without paying attention, thereby affecting the service life and sound insulation effect of the wooden door, thereby ensuring the service life and sound insulation effect of the wooden door body.

[0010] Preferably, the driving assembly includes a push plate and a touch rod, a sliding hole is provided at the connection between the hinge and the wooden door body, and a sliding groove is horizontally symmetrically opened in the wooden door body. The sliding hole is connected with the telescopic groove through the sliding groove. A push plate is provided in the wooden door body, and the push plate is horizontally slidably installed in the sliding groove and the telescopic groove. A card hole is provided in the middle of the push plate, and the card hole is slidably connected to the card block. A touch rod is connected to one end of the push plate close to the hinge, and the touch rod is slidably installed in the sliding hole, and the distal end is located within the rotation range of the hinge. The push plate is made of elastic material.

[0011] When the wooden door body is closed, the wooden door body rotates around the axis of the hinge, and the hinge changes from a separated state to a closed state. When the hinge is closed, the hinge pushes the touch rod, and the touch rod pushes the push plate connected to it. During the process, the touch rod slides in the sliding hole, and the push plate slides in the sliding groove. Under the push of the touch rod, the push plate is squeezed and elastically deformed. During the deformation process, the length of the push plate in the horizontal direction decreases, and at the same time, the distance of the push plate in the vertical direction increases. Since the push plate is installed in the sliding groove and the telescopic groove for horizontal sliding, the block on the sealing pin is connected to the block hole in the middle of the push plate. At this time, the push plate pushes the block to drive the sealing pin to slide in the telescopic groove, and then the sealing pin extends out of the wooden door body. The closing of the hinge drives the touch rod and the push plate to push the sealing pin out of the wooden door body, and then fills the reserved gaps at the upper and lower ends of the wooden door body to ensure the sound insulation effect of the wooden door body.

[0012] Preferably, the recovery component includes a limit pin, a locking block, a spring and a steel wire, a matching groove is provided on the end of the push plate away from the touch rod, the matching groove is trapezoidal, the small diameter end of the matching groove is close to the card hole, the matching groove is horizontally arranged and located in the slide groove, a sliding groove is vertically provided in the wooden door body, the sliding groove is connected with the slide groove, and the limit pin is slidably connected in the sliding groove, the limit pin includes a limit section and a sliding section, the cross-section of the limit pin is the same as the shape of the matching groove, the horizontal cross-sectional area of ​​the limit section decreases from top to bottom, the limit section cooperates with the matching groove, the lower end face of the limit section is connected to the wooden door body through a spring, the large diameter end of the limit section is connected to the sliding section, the lock block is fixedly installed on the connecting rod, and the lock block is connected to the sliding section through a steel wire.

[0013] When the wooden door needs to be opened, the handle is twisted, and the handle drives the connecting rod to rotate and then drives the lock block. When the lock block rotates, the steel wire is pulled to make it fit the surface of the lock block and rotate around the axis of the lock block. At this time, the vertical length of the steel wire is reduced, and the steel wires at both ends move toward the lock block, driving the limit pin in the process, wherein the sliding section slides in the sliding groove, and at the same time drives the limit section to slide in the matching groove until it reaches the highest point. At this time, the matching groove is separated from the limit section, and the elastic potential energy of the push plate is released in the process. However, since the hinge has not been opened at this time, one end of the push plate in the direction of the matching groove slides in the slide groove, and the horizontal length of the push plate increases. The push plate is longer and the vertical distance of the push plate is shortened. Since the push plate is installed in the sliding groove and the telescopic groove for horizontal sliding, the block on the sealing pin is connected to the block hole in the middle of the push plate. At this time, the push plate drives the block to drive the sealing pin to slide in the telescopic groove, and then the sealing pin is retreated from both ends of the wooden door body. The lock block is twisted by twisting the handle and then the steel wire is driven to pull the limit block to release the restriction on the lock block, so that the elastic potential energy of the push plate is released to drive the sealing pin to return to the wooden door body, thereby avoiding the problem of damage to the sealing pin when the user directly opens the wooden door body without paying attention, thereby ensuring the service life of the wooden door body.

[0014] Furthermore, when the handle is twisted, the lock tongue separates from the door frame, pushing the wooden door body, which rotates around the axis of the hinge. The hinges are separated at this time, and when the steel wire pulls the limit pin, the spring on the limit section is stretched. At this time, the elastic potential energy of the spring is released, driving the limit pin downward to reconnect with the matching groove. Since the matching groove is trapezoidal and the small diameter end of the matching groove is close to the card hole, the cross-section of the limit pin is the same as the shape of the matching groove, and the horizontal cross-sectional area of ​​the limit section decreases from top to bottom. At this time, under the action of the limit section and the matching groove, the push plate is pushed to the other side. At this time, the touch rod extends out of the main wooden door and returns between the hinges. The release of the elastic potential energy of the spring drives the limit block to re-match with the matching groove, and at the same time pushes the push plate and the touch rod to reset, preparing for the next closure of the wooden door body.

[0015] Preferably, the sealing pin includes a sliding portion and a deformation portion, the upper end surface of the sliding portion is connected to the block, the cross-section of the deformation portion is U-shaped, a U-shaped groove is coaxially arranged inside the deformation portion, the deformation portion of the inner part of the U-shaped groove is the outer layer substrate, the deformation portion of the outer part of the U-shaped groove is the inner layer substrate, the lower end surface of the sliding portion is connected to the deformation portion, the deformation portion is made of a flexible material, and a melamine coating is provided on the surface of the deformation portion.

[0016] During the opening and closing process of the wooden door body, the sealing pins extend and retract at both ends of the wooden door body, and the lower end face of the sealing pin is squeezed and rubbed with the bottom surface. The friction will cause the sealing pin to wear. At the same time, the continuous squeezing will cause the elastic modulus of the deformation part on the sealing pin to change, and the elastic performance will deteriorate, which will weaken the sound insulation performance of the sealing pin. Therefore, a melamine coating is provided on the surface of the deformation part, which has the characteristics of strong wear resistance, chemical corrosion resistance, smooth surface and good gloss, and can provide good protection for the deformation part. At the same time, a U-shaped groove is coaxially provided inside the deformation part. The design of the U-shaped groove separates the outer substrate of the deformation part from the inner substrate, and relative movement can occur. When the sealing pin extends out of the solid wood body, the sliding part pushes the deformation part, and the lower end face of the deformation part is in contact with the ground and squeezed. The deformation part is made of rubber, which has high elasticity, good flexibility, deformability and wear resistance. And a certain sound insulation, at this time the outer substrate of the deformation part is deformed and bent, and then moves to both sides, as the sliding part continues to push, the lower end of the inner substrate of the deformation part contacts the surface substrate of the deformation part, and the deformation part provides an upward supporting force for the sealing pin, which offsets the thrust generated by the push plate, and the deformation of the deformation part stops. At this time, the U-shaped groove is divided to form two empty chambers, and the U-shaped groove prevents the radial deformation of the inner substrate of the deformation part from acting on the outer substrate of the deformation part. The design of the deformation part surface is provided with a melamine coating to reduce the wear of the sealing pin surface due to friction on the ground. At the same time, the design of the U-shaped groove prevents the radial deformation of the inner substrate of the deformation part from acting on the outer substrate of the deformation part, thereby reducing the deformation of the deformation part, avoiding the wear of the sealing pin due to friction and the change of the elastic modulus of the deformation part on the sealing pin, which reduces the sound insulation performance of the sealing pin.

[0017] Furthermore, when the sealing pin extends out of the solid wood body, the sliding part pushes the deformation part, and the lower end surface of the deformation part is in contact and extruded with the ground. At this time, the outer substrate of the deformation part is deformed and bent, and then moves to both sides. At the same time, the lower end of the inner substrate of the deformation part is in contact with the surface substrate of the deformation part. At this time, the U-shaped groove is divided to form two empty chambers. The sound is gradually attenuated after multiple reflections in the empty chamber. The radial size of the deformation part is increased through extrusion, and the U-shaped groove is divided to form two empty chambers, thereby improving the sound insulation effect of the sealing pin on the gap at both ends of the wooden door body.

[0018] Preferably, the push plate includes a bending section, an installation section and a connecting section. The push plate is in a horn shape, and the center of the push plate is the connecting section. Both ends of the connecting section are connected to one side of the bending section. A card hole is provided on the connecting section. The bending section is made of elastic material, and the other side of the bending section is connected to the installation section. The installation section is located in the slide groove, and the installation section is higher in the vertical direction than the connecting section.

[0019] When the hinge is closed, the touch rod pushes the installation section on the push plate, and the installation section moves in the slide groove, and the thrust is transmitted to the curved section connected to it. The curved section is made of spring steel, which has a high elastic limit, good hardenability, strength and toughness, and can restore to its original shape after repeated stress deformation. At this time, the curved section is deformed, and the length of the curved section in the horizontal direction is reduced. At the same time, the distance of the curved section in the vertical direction increases. Since the push plate is a ram's horn type, the height of the installation section in the vertical direction is higher than the connecting section, and the installation section is connected through the curved section. The vertical movement direction of the curved section points to the connecting section, and the connecting section is connected to the sealing pin. The ram's horn design of the push plate makes the vertical movement direction of the push plate point to the sealing pin, so as to avoid the push plate not moving in the set direction in the vertical direction when the touch rod squeezes the push plate, and the sealing pin cannot be pushed out to fill the gap between the wooden door body and the floor.

[0020] Preferably, an air inlet groove is opened in the wooden door body, the upper end surface of the push plate and the telescopic groove form a closed space, and an air cavity is provided at the position where the lock block and the lock body are located, and the air cavity is connected with the closed space through the air inlet groove.

[0021] When the wooden door body is opened and closed, the hinge squeezes the touch rod and then pushes the push plate to slide in the expansion groove. Since the upper end surface of the push plate and the expansion groove form a closed space, when the push plate pushes the sealing pin to extend out of the wooden door body, the pressure in the closed space is in a negative pressure state, and the external atmospheric pressure acts on the wooden door body. When the push plate pulls the sealing pin back into the wooden door body, the pressure in the closed space increases, and then squeezes the wooden door body from the inside. The wooden door body will deform and crack under the above situation, resulting in the problem of shortening the service life of the wooden door. Therefore, the closed space is designed to be connected with the air cavity through the air intake groove. The air cavity is located at the position where the lock block and the lock body are located. When the push plate pushes the sealing pin to extend out of the wooden door body, the pressure in the closed space is in a negative pressure state. Through the connection of the air intake groove, the air cavity is also in a negative pressure state. In the process of the wooden door body and the door frame, the door frame will squeeze the lock tongue and it will shrink back into the lock body. When the lock tongue extends out of the wooden door body, when the lock tongue enters the lock body, the air cavity is connected to the external environment through the path of the lock tongue movement. Similarly, when opening the wooden door body, it is necessary to pull the sealing pin back into the wooden door body through the push plate. At this time, the pressure in the closed space increases, and through the connection of the air inlet groove, the pressure in the air cavity also increases. When opening the wooden door body, it is necessary to twist the handle, and the handle will drive the connecting rod to twist. The rotating connecting rod drives the lock tongue to retract through the lock body, and the lock tongue is recovered into the lock body. At this time, the air cavity is connected to the outside through the path of the lock tongue movement, and the pressure in the closed space is connected to the air cavity through the air inlet groove, and the contraction of the lock tongue in the air cavity achieves a balance between the air pressure in the closed space and the external air pressure, thereby avoiding the imbalance between the air pressure in the closed space and the external air pressure, which causes the wooden door body to deform and crack, resulting in a shortened service life of the wooden door.

[0022] Furthermore, when the wooden door body is closed, the enclosed space is in a state of negative pressure. The pressure generated by the atmospheric pressure and the thrust generated by the bending of the push plate offset each other. At this time, the extension of the sealing pin is restricted by the negative pressure until the lock tongue is squeezed by the door frame and the lock tongue retracts into the lock body. The enclosed space is connected through the air inlet groove, the air cavity and the lock tongue recovery path, the negative pressure is eliminated, the restriction of the sealing pin is eliminated, and the sealing pin is extended out of the wooden door body at this time, avoiding the sealing pin from rubbing against the ground during the closing process of the wooden door, thereby shortening the service life of the sealing pin.

[0023] When the handle is twisted, the limit block is pulled by the lock block and the steel wire to release the restriction of the limit block on the push plate. The elastic potential energy of the push plate is released to retract the sealing pin into the wooden door body. During the process, the air pressure in the closed space increases. The pressure in the closed space will limit the recovery of the push plate. The lock tongue is recovered by twisting the handle, and the closed space is connected with the external environment through the air inlet groove, the air cavity and the lock tongue recovery path. The air pressure in the closed space is balanced with the external air pressure, and the restriction of the sealing pin is eliminated. The sealing pin is now retracted into the wooden door body, which avoids the sealing pin not being able to be recovered in time during the subsequent opening of the wooden door and rubbing against the ground, thereby shortening the service life of the sealing pin.

[0024] Preferably, an inclined surface is provided at the connection between the expansion groove and the end face of the wooden door body, and compensation blocks are provided at both ends of the deformation part. The compensation block is triangular in cross-section along the axial direction of the deformation part, and the large diameter end of the compensation block is flush with the lower end face of the deformation part. The compensation block is located within the horizontal projection of the inclined surface, and the compensation block is made of elastic material.

[0025] Since the expansion slot is provided in both ends of the wooden door body, there is a certain distance between the inner side wall of the expansion slot and the end faces of both sides of the wooden door body. When the sealing pin is extended to fill the gaps at the upper and lower ends of the wooden door body, the gap corresponding to the distance between the inner side wall of the expansion slot and the end faces of both sides of the wooden door body cannot be filled, and there is still a gap, which reduces the sound insulation effect of the wooden door. Therefore, an inclined surface is provided at the connection between the expansion slot and the end faces of the wooden door body, and compensation blocks are provided at both ends of the deformation part. The compensation block is located in the horizontal projection of the inclined surface. The compensation block is made of rubber, which has high elasticity, good flexibility, deformability, wear resistance and certain sound insulation. When the sealing pin is located in the expansion slot and is compressed, when the sealing pin is extended and contacts the ground or door frame or door frame, the compensation block rebounds and extends from the expansion slot to the inclined surface at the connection between the expansion slot and the end faces of the wooden door body. At the same time, the deformation part on the sealing pin pushes the compensation block to fit with the inclined surface when it is squeezed and deformed. The gap corresponding to the distance between the inner side wall of the expansion slot and the end faces of both sides of the wooden door body is compensated by the compensation block to avoid the existence of the gap, which reduces the sound insulation effect of the wooden door.

[0026] Preferably, the locking block is installed in the air inlet groove, and the locking block includes a clamping block, a fixing pin and a supporting block. The supporting block and the clamping block are arranged on both sides of the connecting rod. The supporting block is fixedly connected to the wooden door body and fits with the connecting rod. The clamping block is slidably installed on the wooden door body, and one side is connected to one end of the steel wire. A clamping groove is provided on the clamping block, and a No. 1 mating surface is inclined on one side of the clamping groove close to the support block. A No. 2 mating surface is inclined on the fixing pin. The fixing pin is installed in the clamping groove by screws, and the No. 2 mating surface is slidably connected to the No. 1 mating surface.

[0027] In the production process of wooden doors, there are many kinds of door locks, which makes the sizes of connecting rods different. Designing corresponding locking blocks for connecting rods of different sizes increases its production cost. Therefore, support blocks and clamping blocks are arranged on both sides of the connecting rod. The support blocks are fixedly connected to the wooden door body and fit with the connecting rod. The clamping blocks are slidably installed on the wooden door body. After the connecting rod is installed, the fixing pin is placed in the clamping groove so that the No. 1 matching surface on the support block and the No. 2 matching surface on the fixing pin fit together and are fixed by screws. In the process of tightening the screws, the fixing pin slides downward. Since the No. 2 matching surface is with the No. 1 matching surface and is inclined, the frame block moves toward the support block during the process and fixes the connecting rod at the same time. By modularizing the locking block, the clamping block is driven to move closer to the support block when fixed by the fixing pin, and the connecting rod is pushed to be locked and fixed. Connecting rods of different sizes can be adapted according to the adjustment of the distance between the support block and the clamping block, thereby reducing the production cost.

[0028] At the same time, during the movement of the clamp, the steel wire connected to it is tightened. The tightened steel wire can transmit power more efficiently, while improving the response speed of the component, ensuring the timely retraction of the sealing pin, and avoiding the sealing pin from rubbing against the ground due to failure to be retracted in time, thereby shortening the service life of the sealing pin.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention cooperates with the sealing pin through the driving component and the recovery component, utilizes the closing of the hinge to drive the sealing pin to extend through the touch rod and the push plate, and simultaneously utilizes the twisting of the handle to drive the steel wire to pull the limit block, thereby releasing the restriction on the lock block, so that the elastic potential energy of the push plate is released to drive the sealing pin to be recovered, thereby solving the problem of damage to the sealing pin when the user directly opens or closes the wooden door body without paying attention, thereby ensuring the service life of the wooden door body.

[0031] 2. The present invention connects the closed space formed by the air cavity and the air inlet groove with the upper end surface of the push plate and the telescopic groove, and utilizes the contraction of the lock tongue when the wooden door is opened and closed to balance the air pressure in the closed space with the external air pressure through the connection of the air cavity and the air inlet groove, thereby avoiding the deformation and cracking of the wooden door body due to the imbalance between the air pressure in the closed space and the external air pressure. At the same time, the contraction of the lock tongue is utilized to prevent the sealing pin from extending and rubbing against the ground or the door frame during the closing or opening of the wooden door.

[0032] 3. The present invention adopts the design of the U-shaped groove in the sealing pin and the two-stage compensation blocks. The design of the U-shaped groove in the deformation part prevents the radial deformation of the inner layer substrate of the deformation part from acting on the outer layer substrate of the deformation part, thereby reducing the deformation of the deformation part and improving the service life. At the same time, extrusion is used to increase the radial size of the deformation part, and the U-shaped groove is divided into two empty chambers to isolate the sound. The compensation block fills the gap, thereby improving the sound insulation effect of the sealing pin on the gap at both ends of the wooden door body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] See also Figures 1 to 11 The present invention provides a durable and strong soundproof wooden door, and the technical solution is as follows:

[0051] Working principle: When installing the wooden door, first fix the door frame 3 to the wall, and connect the wooden door body 1 to the door frame 3 through the hinge 2 at the side. The wooden door body 1 can rotate around the axis of the hinge 2 to open and close the door. A lock body 4 is installed on the other side of the wooden door body 1. A lock tongue 43 is connected to the lock body 4. The lock tongue 43 extends out of the wooden door body 1 and is connected to the door frame 3. When the wooden door body 1 is closed, the lock tongue 43 is connected and matched with the door frame 3, thereby fixing the wooden door body 1. An air cavity 13 is provided at the position of the lock body 4. The lock body 4 is connected to the handle 42 through a connecting rod 41. Due to the wide variety of door locks, the connecting rod 41 has different sizes. In order to meet the adaptation of the wooden door body 1 to different connecting rods 41, a support block 83 and a clamping block 81 are arranged on both sides of the connecting rod 41. The support block 83 is fixedly connected to the wooden door body 1 and fits with the connecting rod 41. The clamping block 81 is slidably installed on the wooden door body 1. After the connecting rod 41 is installed, the fixing pin 82 is placed on the clamping block 81. In the groove 811, the No. 1 matching surface 812 on the support block 83 and the No. 2 matching surface 821 on the fixing pin 82 are fitted and fixed by screws. During the tightening of the screws, the fixing pin 82 slides downward. Due to the No. 2 matching surface 821 and the No. 1 matching surface 812, and the inclined design, the frame block moves toward the support block 83 during the process, and the connecting rod 41 is fixed at the same time. At the same time, during the movement of the clamping block 81, the steel wire 9 connected thereto is tightened, and the tightened steel wire 9 can make the power more effectively transmitted. , and at the same time improve the response speed of the component. When the wooden door needs to be opened, the lock body 4 is unlocked by the key, and the handle 42 is twisted to drive the connecting rod 41 to twist. The rotating connecting rod 41 drives the lock tongue 43 to retract through the lock body 4, and the lock tongue 43 is separated from the door frame 3, thereby releasing the fixation of the wooden door body 1. When the wooden door body 1 needs to be fixed, the wooden door body 1 is overlapped with the door frame 3, and the lock tongue 43 is matched with the lock groove of the door frame 3 to limit the position of the wooden door body 1, thereby fixing the wooden door body 1.

[0052] When the wooden door body 1 needs to be closed, the wooden door body 1 is pushed to rotate around the axis of the hinge 2. At this time, the hinge 2 is closed. During the process, the hinge 2 pushes the touch rod 62, and the touch rod 62 pushes the push plate 6 connected thereto. During the process, the touch rod 62 slides in the slide hole 15, and the mounting section 64 on the push plate 6 slides in the slide groove 16, and the thrust is transmitted to the bent section 63 connected thereto. The bent section 63 is made of spring 73 steel, which has a high elastic limit, good hardenability, strength and toughness, and can restore to its original shape after repeated stress deformation. At this time, the bent section 63 is deformed, and the length of the bent section 63 in the horizontal direction is reduced. At the same time, the distance of the bent section 63 in the vertical direction increases. Since the push plate 6 is a horn-shaped one, the height of the mounting section 64 in the vertical direction is higher than that of the connecting section. The locking nut 51 on the sealing pin 5 is connected to the locking hole 61 in the middle of the push plate 6. At this time, the push plate 6 pushes the locking nut 51 to drive the sealing pin 5 to slide in the telescopic groove 11, thereby making the sealing pin 5 extend out of the wooden door body 1. Since the upper end surface of the push plate 6 and the telescopic groove 11 form a closed space, when the push plate 6 pushes the sealing pin 5 to extend out of the wooden door body 1, the pressure in the closed space is in a negative pressure state. The pressure generated by the atmospheric pressure and the thrust generated by the bending of the push plate 6 offset each other. At this time, the extension of the sealing pin 5 is limited by the negative pressure until the lock tongue 43 is squeezed by the door frame 3 and the lock tongue 43 retracts into the lock body 4. When the lock tongue 43 enters the lock body 4, the air The cavity 13 is connected with the external environment through the movement path of the lock tongue 43, and the closed space is connected with the air cavity 13 through the air inlet groove 12. At this time, the air pressure in the closed space is balanced with the air pressure of the external environment, the negative pressure in the closed space disappears, and the restriction of the sealing pin 5 is eliminated. The sealing pin 5 is extended out of the wooden door body 1 at this time, avoiding the imbalance between the air pressure in the closed space and the external air pressure, which causes the wooden door body 1 to deform and crack. At the same time, it is avoided that the sealing pin 5 is extended and rubbed against the ground during the closing process of the wooden door, thereby shortening the service life of the sealing pin 5. When the sealing pin 5 extends out of the wooden door body 1 and contacts the door frame 3 or the ground, since a U-shaped groove 531 is coaxially arranged in the deformation part 53, and the deformation part 53 is made of rubber, the rubber has high elasticity, good flexibility and deformability. , wear resistance and certain sound insulation. At this time, the outer substrate 533 of the deformation part 53 is deformed and bent, and then moves to both sides. As the sliding part 52 continues to push, the lower end of the inner substrate 532 of the deformation part 53 contacts the surface substrate of the deformation part 53. At this time, the deformation part 53 provides an upward supporting force for the sealing pin 5, which offsets the thrust generated by the push plate 6, and the deformation of the deformation part 53 stops. At this time, the U-shaped groove 531 is divided to form two empty chambers. The sound is gradually attenuated after multiple reflections in the empty chamber. At the same time, the extrusion increases the radial size of the deformation part 53, thereby improving the sound insulation effect. At the same time, the U-shaped groove 531 prevents the radial deformation of the inner substrate 532 of the deformation part 53 from acting on the outer substrate 533 of the deformation part 53, thereby reducing the deformation amount of the deformation part 53.The service life of the sealing pin 5 is improved, and at the same time, the compensation blocks 54 on both sides of the deformation part 53 are in line with the inclined surface 14 at the connection between the expansion groove 11 and the end surface of the wooden door body 1.

[0053] When the door needs to be opened, the handle 42 is twisted, and the handle 42 drives the connecting rod 41 to rotate and then drives the lock block 8. When the lock block 8 rotates, the steel wire 9 is pulled to make it fit the surface of the lock block 8 and rotate around the axis of the lock block 8. At this time, the length of the steel wire 9 in the vertical direction is reduced, and the steel wires 9 at both ends move toward the lock block 8, driving the limit pin 7 in the process, wherein the sliding section 72 slides in the sliding groove 17, and at the same time drives the limit section 71 to slide in the matching groove 66 until it reaches the highest point. At this time, the matching groove 66 is separated from the limit section 71, and the elastic potential energy of the push plate 6 is released in the process, but because the hinge 2 has not been opened, and one end of the push plate 6 slides in the sliding groove 16 in the direction of the matching groove 66. At this time, the length of the push plate 6 in the horizontal direction increases, and the distance of the push plate 6 in the vertical direction decreases. Since the push plate 6 is horizontally slidably installed in the sliding groove 16 and the telescopic groove 11, the block 51 on the sealing pin 5 is connected with the card hole 61 in the middle of the push plate 6. At this time, the push plate 6 drives the block 51 and thus drives the sealing pin 5 to slide in the telescopic groove 11, thereby making the sealing pin 5 retreat from both ends of the wooden door body 1. During the process, the air pressure in the closed space increases, and the pressure in the closed space will limit the push plate 6. The lock tongue 43 is recovered by twisting the handle 42, and the closed space is connected to the external environment through the air inlet groove 12, the air cavity 13 and the recovery path of the lock tongue 43. The air pressure in the closed space is balanced with the external air pressure, and the restriction of the sealing pin 5 is eliminated. The sealing pin 5 is now retracted into the wooden door body 1, and the wooden door body 1 is pushed at this time. The wooden door body 1 rotates around the axis of the hinge 2, and the hinge 2 is separated at this time. When the steel wire pulls the limit pin 7, the spring 73 on the limit segment 71 is stretched. At this time, the elastic potential energy of the spring 73 is released, driving the limit pin 7 downward to re-engage with the The groove 66 is connected. Since the matching groove 66 is trapezoidal and the small diameter end of the matching groove 66 is close to the card hole 61, the cross-section of the limit pin 7 is the same as the shape of the matching groove 66, and the horizontal cross-sectional area of ​​the limit section 71 decreases from top to bottom. At this time, under the action of the limit section 71 and the matching groove 66, the push plate 6 is pushed to move to the other side. At this time, the touch rod 62 extends out of the main wooden door and returns between the hinges 2. The release of the elastic potential energy of the spring 73 drives the limit block to re-match with the matching groove 66, and at the same time pushes the push plate 6 and the touch rod 62 to reset, preparing for the next closing of the wooden door body 1.
