Description

Technical Field

[0001] The present application relates to the field of fixed connection technology, and in particular to an elastic buckle structure of a ticket vending machine. Background Art

[0002] With the intelligent and modern development of self-service, ticket machines provide convenient services in transportation, tourism, educational institutions and other industries. Ticket machines have functions such as two-dimensional barcode activation, induction card recognition, ticket printing, bank card recognition, etc. When printing tickets, the printer paper box usually supplies paper for the printer.

[0003] The Chinese patent announcement number is CN211059128U, and the announcement date is July 21, 2020. The name of the invention is an elastic buckle structure. The application discloses an elastic buckle structure for fixing a drawer-type printer paper box, including a limit module fixed to a certain part and a buckle module rotatably connected to the limit module. An elastic member is fixed to one end of the buckle module, and a groove for clamping is provided at the end of the buckle module away from the elastic member. This buckle structure is fixed between a fixed part inside the ticket machine and the printer paper box, and the buckle module is rotated so that the groove end is clamped with the clamped part of another part. At this time, the elastic part is stretched by force and accumulates elastic force, thereby pushing the groove end to press against the clamped contact part, thereby realizing the fixed connection of the two parts.

[0004] However, in the above-mentioned related technologies, the buckle module always maintains a buckled state under the drive of the elastic member in the absence of external force. Before the printer paper box is clamped inside the ticket machine, it is necessary to manually apply external force to the elastic member end of the buckle module to lift the groove end, and then make the clamped part enter the groove to achieve the clamping. As a result, the buckle module needs to be opened multiple times before and after replacing the printing paper in the printer paper box, which is cumbersome and inconvenient to use.

[0030] The following is combined with Figures 1 to 3 This application is described in further detail.

[0031] The present application embodiment discloses an elastic buckle structure of a ticket vending machine, referring to Figure 1 and Figure 2 , including a mounting seat 2, a clip 3 slidably connected to the mounting seat 2, and an elastic member 4 for driving the clip 3 to snap onto the drawer paper box 1. In the embodiment of the present application, the drawer paper box 1 is set to approach the clip 3 in the horizontal direction, and the side wall closest to the clip 3 can be snapped by the clip 3. The sliding direction of the clip 3 is not parallel to the moving direction of the drawer paper box 1. In the embodiment of the present application, the clip 3 is slidably connected to the mounting seat 2 in the vertical direction, and the elastic member 4 is set as a spring, and the expansion axis of the spring is parallel to the sliding direction of the clip 3.

[0032] Reference Figure 1 and Figure 2Specifically, the mounting seat 2 has an inverted U-shape appearance, the upper surface of the mounting seat 2 is fixedly connected to a certain part or a certain position inside the ticket machine, and two parallel sliding grooves 201 are provided on the side walls on both sides of the mounting seat 2, and the extending direction of the sliding grooves 201 is parallel to the sliding direction of the buckle 3. The buckle 3 includes two parallel sliding rods 301, the sliding rods 301 correspond to the sliding grooves 201 one by one, and the sliding rods 301 can be inserted into the sliding grooves 201 and slidably connected to the inner wall of the sliding grooves 201 along the vertical direction. The two sliding rods 301 are fixedly connected to the same snap plate 302. The snap plate 302 is integrally formed with a snap block 303 at one end close to the drawer paper box 1. A snap groove 304 is penetrated through the lower surface of the snap block 303. The penetration direction of the snap groove 304 is parallel to the plane where the clamped side wall of the drawer paper box 1 is located, so that the clamped side wall of the drawer paper box 1 can be inserted into the snap groove 304.

[0033] Reference Figure 2 and Figure 3 In order to facilitate the locking of the drawer paper box 1 and the clip 3, a linkage member 5 is provided on the drawer paper box 1 to drive the clip 3 to first rise and then fall back. The linkage member 5 includes a connecting rod 6 fixedly arranged on the side wall of the drawer paper box 1 facing the clip 3, and a contact block 7 is fixedly arranged on the side wall of the connecting rod 6 facing the clip 3. The upper surface of the connecting rod 6 is lower than the upper surface of the contact block 7, and when the sliding rod 301 abuts against the bottom end of the sliding groove 201, the bottom end of the clip groove 304 is higher than the upper surface of the contact block 7. A receiving groove 8 is provided on the end surface of the connecting rod 6 facing the clip 3, and the receiving groove 8 is arranged through the sliding direction of the clip 3. A lifting rod 9 is fixedly arranged on the lower surface of the clip plate 302, and the lifting rod 9 corresponds to the contact block 7 one by one. A first guide surface 10 is provided on the lower edge of the lifting rod 9 facing the contact block 7, and the contact block 7 can abut against the first guide surface 10. When the drawer paper box 1 approaches the fastener 3, the abutment block 7 abuts against the first guide surface 10, and pushes the lifting rod 9, the fastener plate 302 and the fastener block 303 to move upward together under the guidance of the first guide surface 10. As the abutment block 7 continues to approach the lifting rod 9 until the lifting rod 9 is inserted into the receiving groove 8, the fastener 3 falls back from the high point, and the fastened side wall of the drawer paper box 1 is fastened to the fastener groove 304.

[0034] Reference Figure 2In order to improve the clamping effect of the drawer paper box 1, the two side walls of the clamping groove 304 in the moving direction of the drawer paper box 1 are set to be inclined, that is, the two side walls opposite to the clamping groove 304 are set to be inclined, and the distance between the two side walls opposite to the clamping groove 304 decreases from bottom to top. A plurality of limit blocks 305 are fixedly arranged on the top inner wall of the clamping groove 304, and the plurality of limit blocks 305 are arranged in sequence along the penetration direction of the clamping groove 304, and there is a distance between two adjacent limit blocks 305. A plurality of reinforcing ribs 101 are fixedly arranged on the top of the clamped side wall of the drawer paper box 1 away from the clamping member 3. When the clamped side wall of the drawer paper box 1 is clamped in the clamping groove 304, the reinforcing ribs 101 are inserted into the gap between two adjacent limit blocks 305.

[0035] Reference Figure 2 and Figure 3 , to facilitate the unlocking of the drawer paper box 1. The limit block 305 is provided with a second guide surface 306 toward the lower edge of the mounting seat 2, and the top of the plugged side wall of the drawer paper box 1 can abut against the second guide surface 306. At the same time, the upper edge of the side wall away from the latch 3 of the abutment block 7 is provided with a third guide surface 11, and the third guide surface 11 and the inner wall of the receiving groove 8 are evenly transitioned. The side wall of the lifting rod 9 away from the first guide surface 10 can abut against the third guide surface 11. When the drawer paper box 1 is pulled out, the latch 3 can be lifted under the guiding effect of the third guide surface 11, and the second guide surface 306 and the inclined side wall of the latch groove 304 can reduce the probability of the drawer paper box 1 colliding with the inner wall of the latch groove 304 when entering and exiting the latch groove 304, so that the drawer paper box 1 can smoothly enter and exit the latch groove 304.

[0036] Reference Figure 2 and Figure 3 Two limiting strips 12 are fixedly arranged on the third guide surface 11, and the side walls opposite to the limiting strips 12 are arranged to be inclined, and the inclination direction is that the distance between the two limiting strips 12 gradually decreases from the abutment block 7 toward the connecting rod 6, and the lifting rod 9 can be located between the two limiting strips 12, and the lifting rod 9 is slidably connected to the inclined inner wall of the limiting strip 12. In addition, the upper edge of the receiving groove 8 is provided with a fourth guide surface 13. This guides the lifting rod 9 to enter and exit the receiving groove 8 more smoothly.

[0037] The implementation principle of the elastic buckle structure of a ticket vending machine in the embodiment of the present application is as follows: when the drawer paper box 1 of the printer is inserted, the abutment block 7 can synchronously approach the lifting rod 9 until it abuts against the first guide surface 10, and the continuously moving abutment block 7 can drive the lifting rod 9 and the buckle 3 to be lifted together under the guidance of the first guide surface 10, until the lifting rod 9 slides and connects to the upper surface of the abutment block 7 to reach the maximum lifting height, at which time the bottom end of the buckle groove 304 is higher than the top of the drawer paper box 1; as the drawer paper box 1 continues to advance, the lifting rod 9 slides and connects to the third guide surface 11, and the lifting rod 9 falls back under the guidance of the third guide surface 11, so that the clamped side wall of the drawer paper box 1 can enter the buckle groove 304, and at the same time, the reinforcing rib 101 of the drawer paper box 1 is inserted into the gap between the limit blocks 305 of the buckle groove 304. The drawer paper box 1 after being clamped is kept fixed relative to the buckle 3 under the rebound force of the elastic member 4. When the drawer paper box 1 of the printer is pulled out, the latch 3 can be driven to rise under the joint guidance of the second guide surface 306 and the third guide surface 11, so that the latched side wall of the drawer paper box 1 leaves the latch groove 304 and is unlocked along the reverse path of the insertion of the drawer paper box 1.

[0038] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
