DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figures 1-4 The present application provides an automatic arrangement device technical scheme.

[0024] An automatic arrangement device comprises:

[0025] A bottom plate 1 is provided with a support 2 fixed thereon;

[0026] An upper rotating rod 3 is provided with two, which are respectively rotatably connected to the two sides of the support 2. The upper rotating rod 3 is rotatably connected to a lower rotating rod 4 on one side of the support 2. Two guide rollers 5 are rotatably connected between the two lower rotating rods 4.

[0027] An elastic device is connected between the corresponding upper rotating rod 3 and lower rotating rod 4. The elastic device comprises a reset spring 6, a first connecting block 7 and a second connecting block 8. The first connecting block 7 is fixed on the upper rotating rod 3, and the second connecting block 8 is fixed on the lower rotating rod. The first connecting block 7 is provided with a first connecting groove 9 with an opening facing the second connecting block 8. The second connecting block 8 is provided with a second connecting groove 10 with an opening facing the first connecting block 7. One end of the reset spring 6 is inserted into the first connecting groove 9, and the other end is inserted into the second connecting groove 10.

[0028] When the swing is in operation, the driving device 19 drives the upper rotating rod 3 to rotate back and forth, so as to realize the swing. Since one end of the reset spring 6 is inserted into the first connecting slot 9 and the other end is inserted into the second connecting slot 10, in order to make the lower rotating rod 4 rotate relative to the upper rotating rod 3, the elastic force of the reset spring 6 needs to be overcome. When the swing is in operation, the upper rotating rod 3 and the lower rotating rod 4 are in the same straight line. When the lower rotating rod 4 encounters an external force, such as a person or an object, the reset spring 6 is deformed due to a larger force, so that the lower rotating rod 4 can rotate relative to the upper rotating rod 3, avoiding damage to it and ensuring the safety of the person. When the external force of the lower rotating rod 4 disappears, the reset spring 6 can drive the lower rotating rod 4 to return to the original position, and the swing can continue to operate.

[0029] As shown in Figure 2 , the first connecting block 7 is fixed with the first side plate 12, and the first side plate 12 is provided with the first connecting bolt 13 which is screwed with the upper rotating rod 3. The first connecting bolt 13 can fix the first connecting block 7 on the upper rotating rod 3.

[0030] As shown in Figure 2 , the first connecting slot 9 penetrates the first connecting block 7, and the end of the first connecting slot 9 away from the second connecting block 8 is provided with an internal thread, and the internal thread is screwed with the limiting screw column 14. In the case of excessive force, the reset spring 6 may need to be replaced, at which time the limiting screw column 14 can be rotated, the limiting screw column 14 is unscrewed from the internal thread, then the reset spring 6 is taken out from the first connecting slot 9, then the new reset spring 6 is inserted into the first connecting slot 9 and the second connecting slot 10, and then the limiting screw column 14 is screwed into the internal thread, which is very convenient to replace.

[0031] As shown in Figure 2 , the second connecting block 8 is fixed with the second side plate 15, and the second side plate 15 is provided with the second connecting bolt 16 which is screwed with the lower rotating rod 4, and the second connecting block 8 is fixed on the lower rotating rod 4 through the second connecting bolt 16.

[0032] As shown in Figure 2 , the first connecting block 7 is fixed with the light emitter 17, and the second connecting block 8 is fixed with the light receiver 18. The light emitter 17 and the light receiver 18 are electrically connected with the driving device 19 or the alarm horn. When the swing is in operation, the light receiver 18 can receive the light signal of the light emitter 17. When the lower rotating rod 4 is forced to rotate relative to the upper rotating rod 3, the light receiver 18 will not be able to receive the light signal, at which time the light receiver 18 can send an electric signal to the driving device 19, and the driving device 19 stops driving the upper rotating rod 3 to rotate or the alarm horn emits an alarm sound.

[0033] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
