Detailed Description

The invention is described in further detail below with reference to the figures and specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The utility model provides a linkage latch hook device, is including the latch hook peg 201 that is located upper and lower latch hook subassembly on first frame 1 and is located second frame 2, upper and lower latch hook subassembly is including upper latch hook subassembly 3 and lower latch hook subassembly 4, and upper latch hook subassembly 3 and lower latch hook subassembly 4 pass through 5 pin joint synchronous motion of connecting rod, and the structure of upper and lower latch hook subassembly is the same completely, upper latch hook subassembly and lower latch hook subassembly all are equipped with latch hook 6, latch hook clamp plate 7, still be equipped with spanner 8 in the first frame, spanner on the first frame links to each other with the latch hook clamp plate, and the latch hook clamp plate is located between spanner and the latch hook, the latch hook clamp plate sets up and forms the seesaw structure in latch hook and spanner top, and when spanner clockwise or anticlockwise movement, drives the latch hook through the latch hook clamp plate and rotates, accomplishes unblock or.

The first rack is used for loading the ticket boxes, the second rack is internally provided with a transmission channel, and the tickets enter the transmission channel of the second rack after coming out of the ticket boxes in the first rack and realize 90-degree steering in the transmission channel. When the ticket box needs to be maintained, the linkage locking hook device is opened, and the first rack and the second rack can be separated. In actual equipment, in order to increase the use efficiency of the equipment, a plurality of ticket boxes are arranged, and the ticket boxes are mostly stacked and distributed up and down. In this embodiment, only the stacking states of the upper and lower ticket boxes are listed, and considering the smoothness of the driving action of the connecting rod, the ticket boxes are mostly even numbers, so that the upper and lower ticket boxes can be provided with only one linkage locking hook device.

The second rack is also provided with a limiting block 202, and the front part of the limiting block is provided with a horizontal positioning groove 203. When the first frame is buckled with the second frame, the limiting column 9 arranged on the first frame is firstly inserted into the horizontal positioning groove of the limiting block arranged on the second frame, so that the first frame and the second frame are accurately positioned in the Z-axis direction. Due to the linkage motion of the upper and lower latch hook components, accurate positioning in the Z-axis direction can be realized only by designing one limiting column and one limiting block.

The first frame is pivoted to the second frame by a shaft 10 disposed on the second frame. The linkage locking hook device and the shaft are respectively positioned at the left side and the right side of the first rack.

The latch hooks 6 of the upper latch assembly and the lower latch assembly are pivoted to the first frame through latch hook rotating shafts 11, the latch hook pressing plate 7 is pivoted to the first frame through pressing plate rotating shafts 12, and the wrench 8 is pivoted to the first frame through wrench rotating shafts 13.

The upper end and the lower end of the connecting rod are respectively positioned on the locking hook pressing plates of the upper locking hook assembly and the lower locking hook assembly.

The upper and lower latch hook assemblies are each provided with a first resilient element 14 to maintain the latch hook in a downward reset and locking force.

The lock hook comprises a lock hook sheet 601, a second elastic element 602, a detection support 603, a sensor blocking sheet 604, a support rotating shaft 605 and a U-shaped sensor 606, the detection support is positioned between the lock hook sheet and the first frame, and the U-shaped sensor is fixed on the first frame.

The detection support is pivoted on the locking hook piece through the support rotating shaft, the second elastic element is installed between the detection support and the locking hook piece, when the first machine frame is in an open state, light emitted by the U-shaped sensor installed on the locking hook cannot be shielded by a sensor separation blade on the detection support, and the system determines that the first machine frame is opened.

The detection support is jacked up by the latch hook hanging shaft when the first frame is buckled with the second frame and shields light emitted by the U-shaped sensor, and the system determines that the first frame is buckled with the second frame in place.

Furthermore, the upper and lower latch hook assemblies are moved synchronously, and the lower latch hook assembly may not be provided with a detection bracket in order to simplify the structure.

The locking hook plate is provided with a supporting sheet 15, the supporting sheet is arranged at one end, far away from the locking hook hanging shaft, of the locking hook plate, one end of a locking hook pressing plate is located above the supporting sheet, and the other end of the locking hook pressing plate is connected with a wrench. One end of the first elastic element is connected to the fixing column 16, the other end of the first elastic element is connected to the locking hook sheet, and the position connected to the locking hook sheet is located above the supporting sheet. The fixed column is fixed on the first rack.

Furthermore, the end, connected with the wrench, of the lock hook pressing plate is of an arc structure, namely the arc structure of the lock hook pressing plate is in contact with the plane structure of the wrench, friction force is reduced, and the connection point of the connecting rod and the lock hook pressing plate is located in the circle center of the arc structure, so that continuity of mechanical transmission is improved.

Because the detection support is located between lock hook piece and the first frame, and the lock hook piece passes through the lock hook rotation axis and realizes the pin joint with first frame, this kind of order has then been injectd the detection support and also need the cluster cover on the lock hook rotation axis, and the detection support must independently rotate again, can not rotate along with the lock hook rotation axis, then will detect the second trompil 18 diameter that is greater than on the lock hook piece of the design of first trompil 17 diameter on the support, when the lock hook piece rotates along with the lock hook rotation axis, the detection support can not rotate along with the lock hook rotation axis under the effect of second trompil, the diameter design size of specific first trompil is decided according to the displacement that detects the support.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
