Description

Technical Field

[0001] The invention relates to a door, in particular to a switchgear room door with concealed door suction and the function of preventing fingers from being pinched. Background Art

[0002] The door panel of the swing-open door is hinged to the door frame through a hinge, and the door frame is installed in the door opening on the wall. In order to keep the door in the open state, a door stopper is also arranged between the rear surface of the door panel and the wall. The existing swing-open door has the following disadvantages: a part of the door stopper is installed on the wall, which will interfere with the sanitation work at the connection between the ground and the wall; and the side with the hinge is easy for young children to put their fingers between the door panel and the door frame and get pinched because they are ignorant. Summary of the invention

[0003] The present invention aims to provide a distribution room door with concealed anti-finger pinching door suction that will not interfere with the hygiene of the connection between the ground and the wall and can prevent children from pinching their fingers. The door suction of the existing door will interfere with the hygiene of the connection between the ground and the wall and the problem that the side of the hinge between the door panel and the door frame will pinch children's fingers.

[0004] The above technical problems are solved by the following technical solutions: a switch room door with concealed door stopper and anti-pinch finger protection, comprising a door frame, a door stopper and a door panel hinged to the door frame by a hinge, the door frame comprising a right vertical side bar, an upper horizontal side bar, a left vertical side bar and a lower horizontal side bar connected together end to end in sequence, the hinge comprising a first mounting ear and a second mounting ear rotatably connected together by an axle pin, the first mounting ear being connected to the right vertical side bar, and characterized in that it also comprises an arc-shaped cover coaxial with the axle pin, the second mounting ear being connected to the door panel at a The arc cover is passed through the door panel, one circumferential end of the arc cover is connected to the right vertical edge strip, and the other end is connected to one end of the connecting steel plate, and the other end of the connecting steel plate is connected to the right vertical edge strip. The arc cover, the connecting steel plate and the right vertical edge strip form a vertical channel, and the door stopper is installed in the vertical channel. The radius of the circle where the outer circumference of the arc cover is located is less than 20 cm, the height of the arc cover is more than 1.2 meters, and the distance between the lower end face of the arc cover and the upper end face of the lower horizontal edge strip is less than 2 mm. This technical solution can avoid pinching children's fingers by setting an arc cover to block the gap at one end of the hinge between the door panel and the door frame. The door stopper does not need to be connected to the wall, so as to avoid interfering with the hygiene of the connection between the wall and the ground.

[0005] Preferably, the door stopper includes a ferromagnetic block connected to the door panel and a permanent magnet block matched with the ferromagnetic block, and the permanent magnet block is connected to the connecting steel plate through a connecting compression spring. The structure is simple, but the technical solution has the following shortcomings: due to space limitations, the deformation of the connecting compression spring is usually small. At this time, if the stiffness coefficient of the connecting spring is too small, the energy absorption effect is poor. If the energy absorption effect is poor, the impact generated during the door opening process is likely to cause the arc cover connecting steel plate to deform, and the deformation will cause the door to open unsmoothly and / or the door stopper cannot resist the impact of the door on the wall during the surface opening and closing process; if the stiffness coefficient of the connecting spring is too large, it is easy to cause the door panel to be bounced open during the door opening process, resulting in the door panel being unable to remain in the open state.

[0006] Preferably, the ferromagnetic block is connected to the door panel by sliding along the width direction of the door panel, and a pressing spring is provided between the ferromagnetic block and the door panel to drive the ferromagnetic block toward the arc cover, and the pressing spring is a compression spring. The inner circumference of the arc cover is provided with a friction layer protruding from the arc cover at one end facing the connecting steel plate, and when the ferromagnetic block squeezes the connecting spring through the permanent magnet block during the door opening process, the friction layer cooperates with the ferromagnetic block to absorb energy. This technical solution enables the friction between the friction layer and the ferromagnetic block to absorb energy during the process of the door suction being adsorbed and the connecting spring contracting, thereby avoiding the shortcomings caused by the above-mentioned connecting spring having too large or too small a stiffness coefficient.

[0007] Preferably, when the ferromagnetic block is disconnected from the permanent magnet block, the friction layer is disconnected from the ferromagnetic block, so as to ensure that the door can be opened smoothly before the door suction is attached.

[0008] Preferably, the door panel is provided with a connecting seat, the connecting seat is provided with a slide bar connected to the ferromagnetic block and extending along the width direction of the door panel, the pressing spring is sleeved on the slide bar, one end of the pressing spring is connected to the ferromagnetic block, and the other end is connected to the connecting seat. The manufacturing is convenient.

[0009] Preferably, the ferromagnetic block compresses the connecting spring through the permanent magnet block so that when the connecting spring contracts by 1 mm, the ferromagnetic block abuts against the friction layer, which can improve the convenience during manufacturing.

[0010] Preferably, one end of the arc cover located on the front surface of the door panel is plugged into the right vertical side bar and connected to the right vertical side bar, and the other end is connected to one end of the connecting steel plate, and the shaft pin is located on the rear surface of the door panel, which is convenient for installation.

[0011] Preferably, the other end of the connecting steel plate is provided with a folded edge turned away from the arc cover, and the folded edge is connected to the right vertical side bar through the connecting steel plate mounting screws, which is convenient for installation.

[0012] Preferably, the door panel is provided with an arc channel coaxial with the shaft pin, the arc cover passes through the door panel through the arc channel, and the gap between the outer peripheral surface of the arc cover and the arc channel is less than 0.8 mm. The gap between the arc cover and the hole of the door panel through which the arc cover passes can be reduced to ensure safety.

[0013] Preferably, the first mounting ear is connected to the vertical side bar through a mounting ear mounting screw, and the arc cover is provided with a screw mounting operation hole aligned with the mounting ear mounting screw, and the diameter of the screw mounting operation hole is 5 mm-10 mm. During assembly, the mounting ear mounting screw is inserted through the screw mounting operation hole to fix the first mounting ear, and a screwdriver is passed through the screw mounting operation hole to rotate the mounting ear mounting screw. This improves the convenience of installing the hinge that is blocked by the arc cover.

[0014] Preferably, the second mounting ear is connected to the end face in the width direction of the door panel, and the first mounting ear is connected to the end face of the vertical side strip facing the width direction of the door panel when the door panel is closed. This allows the door panel to be fixed with screws longer than the thickness of the door panel to improve the connection strength even when the door panel is thin.

[0015] As an alternative, a rubber plug is provided on the screw installation operation hole to improve safety.

[0016] The invention has the following advantages: the door stopper will not interfere with the sanitation of the joint between the ground and the wall; it can prevent children's fingers from being inserted into the gap on one side of the hinge between the door panel and the door frame to cause the phenomenon of pinching the children's fingers, and it has good safety.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, a switch room door with concealed door stopper and anti-pinch finger, comprising a door frame, a door stopper, an arc cover 1 and a door panel 2 hinged on the door frame by a hinge 26. The door frame comprises a right vertical side strip 3, an upper horizontal side strip 4, a left vertical side strip 5 and a lower horizontal side strip 6 connected together end to end in sequence. The hinge comprises a first mounting ear 8 and a second mounting ear 9 connected together by a shaft pin 7. The second mounting ear is connected to the end face in the width direction of the door panel. The first mounting ear is connected to the end face of the vertical side strip facing the width direction of the door panel when the door panel is closed. An arc channel 10 coaxial with the coaxial pin is provided on the door panel. The arc cover passes through the door panel through the arc channel. The gap between the outer peripheral surface 11 of the arc cover and the arc channel is less than 0.8 mm. One end of the arc cover located on the front surface of the door panel is plugged into the right vertical side strip and connected to the right vertical side strip, and the other end is connected to one end of the connecting steel plate 12. The shaft pin is located on the rear surface of the door panel. The other end of the connecting steel plate is turned over in a direction away from the arc cover. The folded edge 13 is connected to the right vertical side strip by the connecting steel plate mounting screw 14. The arc cover, the connecting steel plate and the right vertical side strip form a vertical channel 15. The door stopper is installed in the vertical channel. The radius of the circle where the outer peripheral surface of the arc cover is located is less than 20 cm. The height of the arc cover is more than 1.2 meters. The distance between the lower end surface of the arc cover and the upper end surface of the lower horizontal side strip is less than 2 mm. The first mounting ear is connected to the vertical side strip by the mounting ear mounting screw 16. The arc cover is provided with a screw mounting operating hole 17 aligned with the mounting ear mounting screw. The diameter of the screw mounting operating hole is 5 mm-10 mm. A rubber plug 18 is passed through the screw mounting operating hole. When installing the mounting ear mounting screw 16, pull out the rubber plug, and then operate through the bolt mounting operating hole. When installing the arc cover, the arc cover is inserted into the installation groove on the right vertical side bar after passing through the arc passage from the rear side of the door, and then the folded edge is connected to the right vertical side bar through the connecting steel plate portion mounting screws 14.

[0026] The door stopper includes a ferromagnetic block 19 connected to the door panel and a permanent magnet block 20 matched with the ferromagnetic block. The permanent magnet block is connected to the connecting steel plate through a connecting compression spring 21. The ferromagnetic block is slidably connected to the door panel along the width direction of the door panel, specifically: a connecting seat 22 is provided on the door panel, and a slide bar 23 connected to the ferromagnetic block and extending along the width direction of the door panel is passed through the connecting seat. A pressing spring 24 is provided between the ferromagnetic block and the door panel to drive the ferromagnetic block toward the arc cover. The pressing spring is a compression spring. The compression spring is sleeved on the slide bar. One end of the pressing spring is connected to the ferromagnetic block, and the other end is connected to the connecting seat. The inner circumference of the arc cover is provided with a friction layer 25 protruding from the arc cover at one end facing the connecting steel plate. When the ferromagnetic block is disconnected from the permanent magnet block 20, the friction layer is disconnected from the ferromagnetic block. During the door opening process, when the ferromagnetic block is adsorbed with the permanent magnet and continues to open, the ferromagnetic block squeezes the connecting spring through the permanent magnet block to make the connecting spring contract. When the connecting spring contracts by 1 mm, the ferromagnetic block abuts against the friction layer and the pressing spring is squeezed and deformed to store energy. The reaction force of the pressing spring presses the ferromagnetic block on the friction layer, so that the ferromagnetic block cooperates to absorb friction energy, thereby absorbing the impact force generated when opening the door. When the ferromagnetic block is adsorbed with the permanent magnet block and the connecting spring contracts to the limit position, the door panel is disconnected from the wall 27 where the door frame is installed.
