The specific embodiment is as follows:

the present application will be described in detail with reference to the accompanying drawings.

The handle reversing device comprises a panel 10, a connecting seat 1, a rotating seat 2, an unlocking pin 3 and a protruding piece 1002, wherein the rotating seat 2 is rotatably arranged on the panel 10, a bearing 11 is arranged between the rotating seat 2 and the panel 10, a sheet-shaped driven seat 8 is rotatably arranged on the panel 10, a driven seat 8 sleeve can rotate around the rotating seat 2, and the driven seat 8 is positioned between the panel 10 and the rotating seat 2; two clamping holes 801 are formed in the driven seat 8, an iron transition pin 7 is movably arranged on each clamping hole 801, and the length of the transition pin 7 is longer than the hole depth of the clamping hole 801; the driven seat 8 and the panel 10 are provided with an arc-shaped spring groove 1001, a part of the reset spring 9 is positioned in the spring groove 1001 of the driven seat 8, the other part of the reset spring 9 is positioned in the spring groove 1001 of the panel 10, and both ends of the reset spring 9 are propped against the driven seat 8 and the panel 10; a clamping pin 6 is arranged in a spring hole 202 of the rotating seat 2 through a spring 5, meanwhile, a magnet 4 is fixed on one side of the rotating seat 2, when the clamping pin 6 on the rotating seat 2 is matched with one clamping hole 801, a transition pin 7 in the other clamping hole 801 and the magnet 4 are attracted to each other (the transition pin 7 is attracted to one side of the rotating seat 2 by the magnet 4, but the transition pin 7 does not leave the clamping hole 801); the panel 10 is provided with a tab 1002, and the two edges of the tab 1002 are provided with chamfers, which function to ensure that the tab 1002 can smoothly bear against the transition pin 7 and smoothly disengage from the transition pin 7.

The reversing workflow of the device is described as follows,

in the initial state, when the device is left open, as shown in fig. 3, one end of the clamping pin 6 is positioned in the clamping hole 801 in the driven seat 8, and the other end is positioned in the spring hole 202 of the rotating seat 2. When the handle is turned in the opposite direction of the door opening direction, the latch pin 6 on the rotary seat 2 will gradually rotate right above the boss 1002 (relative to the positions in fig. 3, 4 and 5) when the driven seat 8 and the panel 10 rotate together, and in this process, the boss 1002 on the panel 10 will gradually push the transition pin 7 toward the rotary seat 2, and the movement of the transition pin 7 will drive the latch pin 6 to gradually move toward the spring hole 202 (i.e. let the latch pin 6 gradually leave the latch hole 801, i.e. the state shown in fig. 4).

When the clamping pin 6 moves into the spring hole 202, the reset spring 9 is in a compressed state under the action of the panel 10 and the driven seat 8 (at this time, one end of the reset spring 9 is propped against the driven seat 8, and the other end of the reset spring 9 is propped against the panel 10), when the clamping pin 6 on the rotating seat 2 is completely separated from the clamping hole 801, the driven seat 8 and the rotating seat 2 are not linked, because at this time, one end of the reset spring 9 is propped against the panel 10, the other end of the reset spring 9 is propped against the driven seat 8, and the reset spring 9 is in a compressed state, under the action of the reset spring 9, the driven seat 8 rapidly rotates towards the initial position, and the rotating seat 2 continuously rotates along the opposite direction of the opening direction, when the clamping pin 6 rotates to the other clamping hole 801, the clamping pin 6 enters the clamping hole 801, at this time, the reversing is completed, and the matching relation of all parts after the reversing is completed is shown in fig. 5. When the reversing is completed, the rotating seat 2 just rotates 180 degrees, and the driven seat 8 rotates a certain angle and then rotates to a position before starting rotation under the action of the return spring 9.

The transition pin 7 may not be iron when the above description is needed, and the rotating seat 2 may not be provided with the magnet 4, in which the magnet 4 and the iron transition pin 7 are adopted to ensure that the magnet 4 can attract the transition pin 7 to be motionless in daily use, so that no noise is generated in use. Meanwhile, the device is required to be commutated before being installed on a door, and once the device is installed on the door, the device cannot be commutated after the connecting seat 1 and the lock body in the device are matched together.

It should be noted that, in fig. 1 and fig. 2, the panel 10 is directly used in the present embodiment, and the advantage of using the panel 10 is that it can be directly mounted on a door, and then the handle can be mounted on the rotating base 2 for use. But other mechanisms are possible if the mount does not employ a panel 10, but the mount must have a spring slot 1001 and a tab 1002, wherein the spring slot 1001 may or may not be shaped to conform to the spring 5 on the panel 10, but the function must be the same, and the tab 1002 may or may not be configured to conform to the tab 1002 on the panel 10, but the function must be the same.

Further description is given of fig. 1 and 3, and fig. 4 and 5, the transition pin 7 is a bullet-shaped transition pin 7, and the bullet-shaped transition pin 7 is used to enable the protruding piece 1002 on the panel 10 to smoothly contact with the transition pin 7.

As shown in fig. 1, the connecting seat 1 is matched with the lock body through the connecting hole 101 of the connecting seat, and when the unlocking pin 3 on the rotating seat 2 is not matched with the unlocking pin hole 102 on the connecting seat 1, the connecting seat 1 does not rotate along with the rotating seat 2. The detailed structure of the connection base 1 is shown in fig. 10, and the detailed structure of the rotation base 2 is shown in fig. 8.

As shown in fig. 1 and 7, two unlocking pins 3 are mounted on the rotating base 2, and the two unlocking pins 3 are on a straight line. The two unlocking pins 3 are arranged on the rotating seat 2 because only one unlocking motor (the unlocking motor is used for pushing one end of the unlocking pin 3 into the unlocking pin hole 102 of the connecting seat 1) is arranged on the panel 10, the position of the unlocking motor is not changed, and after the rotating seat 2 rotates 180 degrees to complete the direction change, the unlocking motor can still push the unlocking pin 3. The installation of specific unlocking pin 3 is shown in fig. 7, the unlocking hole 203 is formed in the rotating seat 2, the unlocking pin 3 is located in the unlocking hole 203, a mounting lantern ring 13 is fixed at the orifice of the unlocking hole 203, one end of the unlocking pin 3 penetrates through the mounting lantern ring 13 and is located outside the rotating seat 2, the unlocking pin 3 is sleeved with the unlocking spring 12, one end of the unlocking spring 12 abuts against the unlocking pin 3, the other end of the unlocking spring 12 abuts against the rotating seat 2, when the unlocking pin 3 moves into the unlocking pin hole 102, the unlocking spring 12 is continuously compressed, and when external force does not squeeze the unlocking pin 3 to move into the unlocking pin hole 102 any more, the unlocking spring 12 drives the unlocking pin 3 to be separated from the unlocking pin hole 102, but due to the existence of the mounting lantern ring 13, the unlocking pin 3 cannot be sprung away from the mounting lantern ring 13 by the spring 5. In fig. 7, the mounting collar 13 and the unlocking pin hole 102 are fixed in a plurality of ways, and preferably are connected and fixed in a riveting way.

As shown in fig. 1, 3, 4, 5, 7 and 8, the rotating base 2 is provided with an idle slide 201, and the connecting base 1 is provided with a protruding column 103, the protruding column 103 is located in the idle slide 201, and the idle slide 201 is a 180-degree arc slide. Since the rotating base 2 rotates 180 degrees and the connecting base 1 installed on the rotating base 2 also needs to rotate 180 degrees when the device is used for reversing, an idle slide 201 with 180 degrees radian is arranged on the rotating base 2, and a protruding column 103 is arranged on the connecting base 1. When reversing, one side of the idle slide 201 butts against the protruding column 103, so that the rotating seat 2 can drive the connecting seat 1 to rotate together; of course, during the actual transportation and storage process, the connection seat 1 and the rotating seat 2 are easy to rotate relatively, so that the idle slide 201 does not necessarily support the protruding column 103 during the actual reversing operation, the connection seat 1 does not necessarily rotate synchronously along with the rotating seat 2, and when the connection seat 1 and the rotating seat 2 do not rotate synchronously, the connection seat 1 needs to be manually rotated after the reversing operation is completed, so that the protruding column 103 supports one side of the idle slide 201; when a very compact situation occurs, the rotating seat 2 rotates 180 degrees, and since the radian of the idle slide 201 is 180 degrees, the connecting seat 1 does not need to rotate, but when the connecting seat 1 does not rotate, the connecting seat 1 needs to be manually rotated 180 degrees, but in this case, the contact surface between the connecting seat 1 and the rotating seat 2 must be very smooth, so the probability of occurrence of the phenomenon is very small. Therefore, in the process of reversing, the connection seat 1 may rotate synchronously with the rotation seat 2, or the rotation seat 2 rotates first and then the connection seat 1 rotates (the position of the connection seat 1 needs to be manually adjusted after reversing), or the connection seat 1 does not rotate in the whole course in the process of reversing (the occurrence probability is very small, and the position of the connection seat 1 needs to be manually adjusted after reversing is completed).

As can be seen from the above, the arc of the idle slide 201 is set to 180 degrees, and the protruding post 103 is provided on the connection base 1, so that the connection base 1 can be very conveniently and quickly adjusted in place after the reversing is completed. The above only illustrates an effect of the idle slide 201, since the idle handle phenomenon usually occurs when a user uses the lock, that is, when the unlocking pin 3 is not matched with the unlocking pin hole 102 on the connecting seat 1, the handle is rotated along the unlocking direction only to drive the rotating seat 2 to rotate around the panel 10 and not to drive the connecting seat 1 to rotate together, and since the connecting seat 1 is matched with the rotating seat 2 and the connecting seat 1 is matched with the lock body, the connecting seat 1 does not rotate during the process, and the rotating seat 2 rotates, so the protruding column 103 on the connecting seat 1 slides in the idle slide 201 of the rotating seat 2. The lock is designed with the handle idle function to improve the safety of the lock, but if the lock can give up the handle idle function, the connecting seat 1 may not be provided with the protruding column 103, and the rotating seat 2 may not be provided with the idle slide 201. The detailed structure of the connecting seat 1 is shown in fig. 10, and the structure of the idle slide 201 on the rotating seat 2 is shown in fig. 8.

The structure of the driven seat 8 is shown in fig. 9, the spring groove 1001 on the driven seat 8 is formed by 2 straight plates and 1 circular arc plate, and one end of the return spring 9 abuts against one of the straight plates during the rotation of the driven seat 8.

In the above 10 drawings, fig. 3 should be described, only a part of the structure of the panel 10 is shown in fig. 3, and other devices on the panel 10 that are not related to the reversing function are not shown. While reference is made to fig. 1, 2, 3, 4, 5 and 7, the device is shown as being mounted on a door, and the drawings are rotated 90 degrees.

Meanwhile, fig. 3, fig. 4 and fig. 5 should be described, wherein one end of the spring 5 may be fixed with the rotating seat 2, or one end of the spring 5 may not be fixed with the rotating seat 2; meanwhile, the clamping pin 6 can be fixed with the spring 5 or not.

The foregoing description is only of the preferred embodiments of the present application, and is not intended to limit the scope of the application, but rather is intended to cover all equivalent structures as modifications within the scope of the application, either directly or indirectly, as may be contemplated by the present application.
