Description

Technical Field

[0001] The utility model belongs to the technical field of door switches, and more specifically, it particularly relates to a self - sucking door switch. Background Art

[0002] A door switch is also a door lock. A door lock is a hardware part designed for the privacy of a space. Its basic structure includes a lock body and a lock catch. The lock body is assembled on the door, and the lock catch is assembled on the door frame. Usually, the lock body includes a lock base and a lock tongue. The lock base is statically assembled on the door, and the lock tongue is movably assembled relative to the lock base. When locking the door, the lock tongue elastically collides with the lock catch plate through an elastic mechanism and finally inserts the lock tongue into the lock catch to complete the door - locking operation.

[0003] For the lock tongue of the existing - structure door lock, its normal state is to protrude from the lock body. However, the lock tongue protruding from the lock body is easy to scratch the clothes of the human body, causing the clothes to be damaged, and even causing harm to the user's body if the user accidentally touches the lock tongue. On the other hand, when closing or opening the door, the lock tongue and the door frame will collide and rub against each other, causing noise and also causing wear to the lock tongue, the door frame, and the lock catch, reducing their service life. Summary of the Utility Model

[0004] In order to solve the above - mentioned technical problems, the utility model provides a self - sucking door switch to solve the problems that the lock tongue of the existing door lock protruding from the lock body is easy to scratch the clothes of the human body, causing the clothes to be damaged. On the other hand, when closing or opening the door, the lock tongue and the door frame will collide and rub against each other, causing noise and also causing wear to the lock tongue, the door frame, and the lock catch, reducing their service life.

[0005] The purpose and effect of a self - sucking door switch of the utility model are achieved by the following specific technical means:

[0006] A self - sucking door switch includes a switch frame; the switch frame is located on the left side of the limit frame. A sealing cover plate is fixedly connected to the front end position of the switch frame. A resetable transmission shaft is arranged at the upper - middle position of the switch frame. The front and rear ends of the transmission shaft are respectively inserted into the interior positions of a mounting plate. A handle is fixedly connected to each of the left and right sides of the transmission shaft. A transmission part is arranged at the rear - middle position of the transmission shaft. A transmission rod is slidably connected to the upper - interior position of the switch frame. A baffle is arranged at the middle - right position of the transmission rod, and the baffle position of the transmission rod is in contact with the upper position of the transmission part. A magnetic part A is arranged at the right position of the transmission rod. A spring tongue is slidably connected to the left position of the transmission rod.

[0007] According to an embodiment of the utility model, the two mounting plates are symmetrically designed, and the two handles are symmetrically designed.

[0008] According to an embodiment of the present utility model, a spring member is sleeved on the outer end of the left side of the transmission rod. The right side of the spring member is in contact with the left side of the transmission member, and the left side of the spring member is in contact with the spring tongue.

[0009] According to an embodiment of the present utility model, a door lock is provided at the lower position inside the switch frame, and the door lock is located below the transmission shaft.

[0010] According to an embodiment of the present utility model, a magnetic member B is provided at the upper right position of the switch frame, and the magnetic member B is located on the right side of the magnetic member A. A magnetic member C is provided at the upper middle position of the limit frame, and a lock hole is provided at the lower middle position of the limit frame. The lock hole position of the limit frame corresponds to the door lock.

[0011] According to an embodiment of the present utility model, when the transmission shaft is in the reset state, the magnetic member C of the limit frame and the spring tongue are magnetically adsorbed to each other.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] When the limit frame is installed at the door frame position so that the switch frame corresponds to the limit frame, when holding the handle to rotate the transmission shaft, the transmission shaft will drive the transmission rod to move to the right side through the cooperation of the transmission member. At this time, it drives the magnetic member A to move to the right, reducing the distance between the magnetic member A and the magnetic member B. After the magnetic member A and the magnetic member B approach, there is a magnetic adsorption effect. The magnetic member A and the magnetic member B are adsorbed and attached to each other, and the whole transmission rod moves to the right side again. The spring tongue position will enter the inside of the switch frame. In the state where the transmission shaft is reset, through the adsorption and attachment of the magnetic member A and the magnetic member B, the spring tongue is still inside the switch frame. When closing the door panel, the spring tongue will not rub against the door frame position, nor will it catch the clothes of the personnel.

[0014] When the door panel is closed at the door frame position, the switch frame and the limit frame are in a flush state. At this time, the magnetic member C designed on the limit frame and the spring tongue are magnetically adsorbed to each other, pulling the spring tongue to reset and extend. The spring tongue will enter the upper position inside the limit frame for limiting, completing the door locking effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment 1:

[0026] As shown in Attachment Figure 1 to Attachment Figure 5 shown:

[0027] The utility model provides a self - suction door switch, which comprises a switch frame 1; the switch frame 1 is located on the left side of the limit frame 2. At the front end of the switch frame 1, a sealing cover plate 101 is fixedly connected. After installation, the sealing cover plate 101 ensures that no dust enters the inside of the switch frame 1, further improving the service life of the overall parts of the switch frame 1. At the upper middle position of the switch frame 1, a resetable transmission shaft 102 is arranged. The front and rear ends of the transmission shaft 102 are respectively inserted into the inside of a mounting plate 103. On the left and right sides of the transmission shaft 102, a handle 104 is fixedly connected respectively. At the middle rear position of the transmission shaft 102, a transmission part 105 is arranged. At the upper part inside the switch frame 1, a transmission rod 106 is slidably connected. At the middle right position of the transmission rod 106, a baffle is arranged, and the baffle position of the transmission rod 106 is attached to the upper position of the transmission part 105. At the right side of the transmission rod 106, a magnetic part A109 is arranged. At the left side of the transmission rod 106, a spring tongue 108 is slidably connected. The two mounting plates 103 are symmetrically designed, and the two handles 104 are symmetrically designed. At the outer left end position of the transmission rod 106, a spring part 107 is sleeved. The right side of the spring part 107 is attached to the left side position of the transmission part 105, and the left side of the spring part 107 is attached to the spring tongue 108. At the lower part inside the switch frame 1, a door lock 111 is arranged, and the door lock 111 is located below the transmission shaft 102.

[0028] Wherein, at the upper right position of the switch frame 1, a magnetic part B110 is arranged, and the magnetic part B110 is located on the right side of the magnetic part A109. At the upper middle position of the limit frame 2, a magnetic part C201 is arranged. At the lower middle position of the limit frame 2, a lock hole is arranged, and the lock hole position of the limit frame 2 corresponds to the door lock 111. When the transmission shaft 102 is in the reset state, there is magnetic adsorption between the magnetic part C201 of the limit frame 2 and the spring tongue 108.

[0029] During use:

[0030] Install the switch frame 1 at the internal position of the door panel, and then install the limit frame 2 at the door frame position so that the positions of the switch frame 1 and the limit frame 2 correspond to each other. When holding the handle 104 and rotating the transmission shaft 102, the transmission shaft 102 will drive the transmission rod 106 to move to the right through the cooperation of the transmission part 105. At this time, it drives the magnetic part A109 to move to the right, reducing the distance between the magnetic part A109 and the magnetic part B110. After the magnetic part A109 and the magnetic part B110 approach, there is a magnetic adsorption effect, and the magnetic part A109 and the magnetic part B110 are adsorbed and fitted together. The whole transmission rod 106 moves to the right again, and the position of the spring tongue 108 will enter the internal position of the switch frame 1. In the state where the transmission shaft 102 is reset, due to the adsorption and fitting of the magnetic part A109 and the magnetic part B110, the spring tongue 108 is still in the internal position of the switch frame 1. When closing the door panel, the spring tongue 108 will not rub against the door frame position, nor will it catch on the clothes of the personnel.

[0031] Embodiment 2:

[0032] Based on the first embodiment, when the door panel is closed at the door frame position, the switch frame 1 and the limit frame 2 are in a flush state. At this time, the magnetic part C201 designed on the limit frame 2 and the spring tongue 108 are magnetically adsorbed to pull the spring tongue 108 to reset and extend. The spring tongue 108 will enter the upper internal position of the limit frame 2 for limiting, completing the door locking effect.
