Detailed implementation

[0026] The present utility model will be further described in detail below with reference to the drawings and embodiments.

[0027] Embodiment: As Figures 1-5 shown, this embodiment provides a barrier-free sliding two-way opening door, including a door panel 1, a hydraulic door closer 3 and a two-link assembly 4. An upper mounting groove 11 is provided on one side of the upper end of the door panel 1; the hydraulic door closer 3 includes an upper track 31, a connecting rod 32, a movement mechanism 33 and a panel 34. The upper track 31 is fixedly installed on the inner top wall of the door frame 2; the movement mechanism 33 is fixedly embedded in the upper mounting groove 11. The upper end of the movement mechanism 33 is fixedly connected to the panel 34, and the panel 34 is fixedly installed at the opening of the upper mounting groove 11; the movement mechanism 33 has a rotating shaft passing through the panel 34, one end of the connecting rod 32 is fixedly connected to the rotating shaft, and the other end of the connecting rod 32 is slidably arranged on the upper track 31 through an upper slider; the two-link assembly 4 includes a lower track 41, a long rod 42 and a short rod 43. The lower track 41 is fixedly installed on one side of the bottom end of the door panel 1 opposite to the upper mounting groove 11 up and down. One end of the long rod 42 is slidably arranged on the lower track 41 through a lower slider; the other end of the long rod 42 is hinged to one end of the short rod 43, and the other end of the short rod 43 is hinged to the inner bottom wall of the door frame 2.

[0028] Through the above settings, at the fixed end of the door panel 1, the traditional hinge connection is optimized into a hydraulic door closer 3 and a two-link assembly 4. In the natural state, the door panel 1 is in the closed position. When the door panel 1 needs to be opened, push the door panel 1, and the door panel 1 is opened under the cooperation of the hydraulic door closer 3 and the two-link assembly 4. Since both the hydraulic door closer 3 and the two-link assembly 4 are installed at the gap between the door panel 1 and the door frame 2, no matter whether the door panel 1 is pushed from the front or the back, the door panel 1 can be opened, and the door panel 1 can be opened in two directions, which is convenient for disabled people to pass through, greatly improving the daily life of disabled people and being suitable for popularization and use in daily life. By setting the hydraulic door closer 3, when the door panel 1 is in the pushed-open state and the external thrust is removed, the door panel 1 will automatically return to the closed position, which is simple and convenient to operate and reduces the opening and closing resistance of the door panel 1. By setting the two-link assembly 4, the bottom of the door panel 1 is connected to the door frame 2, realizing the synchronous movement of the lower part and the upper part of the door panel 1, and improving the installation stability of the door panel 1 and the stability of the opening and closing actions.

[0029] Both the hydraulic door closer 3 and the two-link assembly 4 can use existing products, and their working principles also belong to existing content. For example, the basic components of a door closer include a support and guide, a transmission gear, a return spring, a check valve, a rack plunger, a throttle valve core, and a housing, end caps, sealing rings, and connecting rods. The housing and the connecting rod play the role of fixing the door closer and connecting the door leaf and the door frame. When the door is opened, the door body drives the connecting rod to move, causing the transmission gear to rotate and driving the rack plunger to move to the right. During the rightward movement of the plunger, the spring is compressed, and the hydraulic oil in the right chamber is also pressurized. The check valve ball on the left side of the plunger opens under the action of the oil pressure, and the hydraulic oil in the right chamber flows to the left chamber through the check valve. When the opening process is completed, since the spring is compressed during the opening process, the accumulated elastic potential energy is released, pushing the plunger to the left, driving the transmission gear and the door closer connecting rod to rotate, and closing the door. During the spring release process, since the hydraulic oil in the left chamber of the door closer is compressed, the check valve is closed, and the hydraulic oil can only flow out through the gap between the housing and the plunger, and returns to the right chamber through the small holes on the plunger and two flow channels equipped with throttle valve cores. Therefore, the hydraulic oil constitutes a resistance to the spring release, that is, buffering is achieved through throttling, and the closing speed of the door is controlled. The throttle valve on the valve body can be adjusted to control the variable closing speed in different stroke segments.

[0030] Specifically, the sliding direction of the upper slider connected to the connecting rod 32 on the upper track 31 is parallel to the length direction of the upper door frame 2, and the sliding direction of the lower slider connected to the long rod 42 on the lower track 41 is parallel to the length direction of the bottom end of the door panel 1.

[0031] In a barrier-free sliding two-way opening door of this embodiment, an electromagnetic lock 5 is installed on the door panel 1 to lock the door panel 1 in the closed position, improving safety.

[0032] In a barrier-free sliding two-way opening door of this embodiment, a voice control / touch control device 51 is installed on the door panel 1. The voice control / touch control device 51 is electrically connected to the electromagnetic lock 5. The voice control / touch control device 51 is installed at a position slightly below the middle of the door panel 1 and is electrically connected to the electromagnetic lock 5, and is used to control the opening and closing of the electromagnetic lock 5 by one or more of a manual mechanical method, a voice control method, and a touch control method. Such a setting facilitates disabled people to open and close the door in various ways.

[0033] The opening and closing of the electromagnetic lock 5 are realized through the voice / touch control device. The voice control switch adopted in this embodiment absorbs the working principle of the voice-activated light switch. It is a voice-activated delay switch, an energy-saving electronic switch without internal contact points. In a specific environment, the sound effect is used to stimulate the pickup for sound-electricity conversion to control the turning on of the electrical appliance, and the power supply can be automatically disconnected after a delay. The power supply of the magnetic lock is controlled by the voice control switch to achieve the effect of locking and unlocking the door.

[0034] Preferably, the sound / touch device is set at the lower middle position on the right side of the door panel 1, which is convenient for disabled persons to operate.

[0035] In a barrier-free sliding two-way opening door of this embodiment, it further includes an access control device. The access control device is electrically connected to the electromagnetic lock 5. The access control device is used to control the power on and off of the electromagnetic lock 5 and to identify personnel. When the access control device correctly identifies the personnel, it controls the power of the electromagnetic lock 5 to be disconnected, and the electromagnetic lock 5 loses suction and unlocks.

[0036] Specifically, the design of the magnetic lock or electromagnetic lock 5 is the same as that of an electromagnet. It uses the principle of electro-magnetic induction. When current passes through the silicon steel sheet, the electromagnetic lock 5 will generate a strong suction force to tightly hold the adsorption iron plate to achieve the effect of locking the door. The working principle of the magnetic lock is to control the opening and closing of the door through electromagnetic force. When current passes through the silicon steel sheet, the electromagnetic lock 5 will generate a strong suction force, thus tightly holding the adsorption iron plate to achieve the effect of locking the door. When the access control device that controls the power of the electromagnetic lock 5 correctly identifies the personnel, it will cut off the power supply, and the electromagnetic lock 5 loses suction and the door can be opened. Because the electromagnetic lock 5 has no complex mechanical structure and the structure of the lock tongue, it is especially suitable for the access control of escape doors or fire doors. In this embodiment, a magnetic lock is used as the barrier-free door lock.

[0037] In a barrier-free sliding two-way opening door of this embodiment, the electromagnetic lock 5 is a 180KG recessed electromagnetic lock 5.

[0038] In a barrier-free sliding two-way opening door of this embodiment, ventilation holes 12 are opened at the lower position on the door panel 1. With this setting, the door panel 1 can be used as a bathroom door.

[0039] In a barrier-free sliding two-way opening door of this embodiment, a glass observation window 6 is provided on the door panel 1. The glass observation window 6 is located at the lower middle position of the door panel 1. With this setting, it is convenient for disabled persons or caregivers to observe the people opposite the door.

[0040] In a barrier-free sliding two-way opening door of this embodiment, the glass on the glass observation window 6 is frosted glass.

[0041] In a barrier-free sliding two-way opening door of this embodiment, the size of the frosted glass is 150mm * 500mm.

[0042] In a barrier-free sliding two-way opening door of this embodiment, the glass observation window 6 is located at the position 1 meter above the height of the door panel 1, which is convenient for observation.

[0043] In a barrier-free sliding two-way opening door of this embodiment, a barrier-free handrail 13 made of metal material is provided on the door panel 1. The barrier-free handrail 13 is located at the lower middle position of the door panel 1. With this setting, it is convenient for disabled persons to hold the barrier-free handrail 13 and push the door panel 1.
