Detailed Description
The invention is described in detail below with reference to the attached drawing figures:
as shown in fig. 1, the opening device 110 includes a support plate 111. The supporting plate 111 is used for supporting and mounting other components.
As shown in fig. 1 and 2, two first pins 112 and two second pins 113 are disposed on the support plate 111. The first pin 112 and the second pin 113 are arranged at an interval from top to bottom, and the first pin 112 is located above the second pin 113. The support plate 111 is provided with a first electromagnet 114 and a second electromagnet 115. The first electromagnet 114 and the second electromagnet 115 are arranged at an interval from top to bottom. The first electromagnet 114 is positioned above the second electromagnet 115. The first electromagnet 114 and the second electromagnet 115 are both located at the widthwise middle portion of the support plate 111, preferably at the widthwise center position. Vertically, the first pin 112 is located below the first electromagnet 114, and the second pin 113 is located above the second electromagnet 115.
The two first swing hooks 121 are respectively located on the left and right sides of the first electromagnet 114 and the second electromagnet 115. The two first swing hooks 121 are preferably symmetrically arranged with respect to a center line of the support plate 111 extending in the vertical direction. The middle of each first swing hook 121 is sleeved on the first pin 112, and the first swing hook 121 can rotate around the first pin 112. The first swing hook 121 protrudes upward and downward from the first pin 112, respectively. The upper half portion 122 of the first swing hook 121 is opposite to the first electromagnet 114, and can be attracted by the first electromagnet 114 to be close to the first electromagnet 114. When the upper half parts 122 of the two first swing hooks 121 are attracted by the first electromagnet 114, the first swing hooks 121 rotate around the first pin 112, and the lower half parts 123 of the two first swing hooks 121 are away from each other. The lower end of the first swing hook 121 is provided with a first hook body 124. A first spring 116 is disposed between the upper half 122 of each first swing hook 121 and the first electromagnet 114. When the upper half 122 of the first swing hook 121 approaches the first electromagnet 114, the first spring 116 is compressed to deform the first spring 116, thereby generating an elastic force. The elastic force is applied to the first swing hook 121 to restore the first swing hook 121. In the example shown, the first springs 116 are two in number.
The two second swing hooks 131 are respectively located at the left and right sides of the second electromagnet 115. The two second swing hooks 131 are preferably symmetrically disposed with respect to a center line of the support plate 111 extending in the vertical direction. The upper ends of the two second swing hooks 131 are mounted on the second pin 113 and can rotate around the second pin 113. The second electromagnet 115 can attract the second swing hook 131 to make the second swing hook 131 rotate around the second pin 113. The lower end of the second swing hook 131 is provided with a second hook body 132. When the second electromagnet 115 has magnetism, the second swing hook 131 can be attracted to swing the second swing hook 131 around the second pin 113, so that the second hook 132 is close to the second electromagnet 115, that is, the two second hooks 132 are close to each other. A second spring 117 is disposed between the two second swing hooks 131. The second spring 117 is located below the second electromagnet 115. Two ends of the second spring 117 respectively abut against the two second swing hooks 131. When the two second hooks 132 approach each other, the second spring 117 is compressed and deformed by pressing the second spring 117. The second spring 117 is deformed to generate an elastic force, which can restore the two second swing hooks 131.

The two second pulley assemblies 180 are arranged side by side left and right and located on the left and right sides of the first bracket 161. Both ends 1841 of the third rope 184 are respectively connected to the two wire hooks 140 on the outer side, and the third rope 184 passes around the two third pulleys 182 and passes through the through groove 168. The third cord 184 is vertically movable within the channel 168. One end 1851 of the fourth rope 185 is fixedly coupled to the support plate 111, and the other end is provided with the second connector 186. The fourth rope 185 passes around two fourth pulleys 183 and rides on the fourth pulleys 183. The fourth cord 185 passes through the channel 168 and is vertically movable within the channel 168. The two wire hooks 140 located at the outer side can be lifted synchronously, or when one wire hook is fixed and the other wire hook is lifted, the third pulley 182 and the second bracket 181 can be driven to lift, and then the fourth pulley 183 can be driven to lift. Lifting of the second linkage 186 may be accomplished by the second pulley assembly 180. The second connector 186 may be constructed in any suitable manner, such as a plug hook.
