Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission device technology, and more specifically, to a card dispensing device with a self-locking structure. Background Technology

[0002] Existing simple card dispensing devices generally use springs to adjust the height of the slider, relying on gravity to return the slider to its original position. This has two major drawbacks: first, the slider is prone to contacting the lower surface of the card during the return process, causing scratches; second, the force is concentrated when pushing the card, which can easily damage the edges of the card, affecting the integrity of the card and the reliability of the device, making it difficult to meet the stability requirements of pushing card-type products. Utility Model Content

[0003] The purpose of this invention is to provide a card dispensing device with a self-locking structure to solve the problems of existing card dispensing devices easily scratching cards and having concentrated force points.

[0004] To solve the above problems, this utility model first provides a card dispensing device with a self-locking structure, including: a transmission mechanism, comprising a chain drive section and a linear limiting track arranged at intervals and parallel to each other; a card pushing mechanism, located between the chain drive section and the linear limiting track; a mounting groove is provided on the side of the card pushing mechanism near the chain drive section, and a sliding slider is installed inside the groove, the sliding slider being coaxially fixed with a positioning chain link on the chain drive section; a cooperating transmission component is provided on the side of the card pushing mechanism near the linear limiting track, which can cooperate with and connect with the linear limiting track and slide along its layout direction; when the positioning chain link moves to both ends of the chain drive section, it drives the sliding slider to move in the mounting groove, causing the card pushing mechanism to turn; a self-locking slider is limited and installed in the slider mounting part on the card pushing mechanism, and an elastic element is provided between its bottom and the slider mounting part; the self-locking slider... The block has a heart-shaped limiting groove, and the slider mounting part is equipped with a self-locking slider that can slide along the limiting groove; its top has an upwardly protruding card pushing block; the limiting groove has an upper end point and a lower end point. When the elastic element is in its natural state, the self-locking slider is located at the lower end point; when the elastic element is in a compressed state, the self-locking slider slides to the upper end point; a card placement mechanism is located above the card pushing mechanism, and its bottom has a card pushing groove, into which the card pushing block can extend to push the card; the two ends below the card placement mechanism are respectively provided with a first limiting part and a second limiting part; the self-locking slider has a first mating part on the side near the first limiting part, which can be limited and mated with the first limiting part; the self-locking slider has a second mating part on the side near the second limiting part, which can be limited and mated with the second limiting part.

[0005] With this design, the self-locking slider, through the heart-shaped limiting groove and the inclined surface, disengages from the card upon returning to its original position, completely preventing scratches and achieving zero-contact return. The card pushing block increases the contact area with the card, dispersing edge stress and reducing edge damage. The end-point locking mechanism of the heart-shaped groove ensures smooth movement and a more stable mechanical self-locking process. The positioning chain link drives the steering slider to move up and down within the mounting slot, achieving precise steering and reciprocating motion. The entire system achieves automatic reciprocating motion through the mechanical cooperation of chain drive and inclined surface compression, eliminating the need for complex electronic control components. The structure is stable and suitable for various card pushing scenarios, effectively enhancing structural stability and applicability.

[0006] Furthermore, the first limiting part is provided with a first limiting inclined surface, and the first mating part is a first mating inclined surface, which can abut and press against the first limiting inclined surface; the second limiting part is provided with a second limiting inclined surface, and the second mating part is a second mating inclined surface, which can abut and press against the second limiting inclined surface.

[0007] Furthermore, an installation limiting part is provided above the slider mounting part, and an installation mating part is provided below the self-locking slider, wherein the installation mating part and the installation limiting part are mutually limiting and mating.

[0008] Furthermore, the elastic element is a spring, which in its natural state can push the self-locking slider upward to reset, and the self-locking slide rod is located at the lower end point; when the elastic element is in a compressed state, the self-locking slide rod slides to the upper end point.

[0009] Furthermore, the self-locking slider is symmetrically provided with the limiting grooves on both sides, and a mounting hole is provided at the bottom of the slider mounting part; the self-locking slider includes a bottom connecting crossbar, an extending vertical bar, and a top connecting crossbar; the bottom connecting crossbar is installed through the mounting hole, and the extending vertical bars are connected and installed on both sides of the bottom connecting crossbar, and the upper end of the extending vertical bars is provided with the top connecting crossbar extending in the direction corresponding to the limiting groove; the length of the top connecting crossbar is less than that of the bottom connecting crossbar, and one end of the top connecting crossbar can extend into the limiting groove and slide.

[0011] Furthermore, the height of the card pushing block is greater than 1 / 2 of the card thickness and less than or equal to the card thickness, and its end face in contact with the card is flat.

[0012] Furthermore, the slider mounting part is provided with a ball bearing guide rail, and the self-locking slider slides up and down in the slider mounting part via the ball bearing guide rail. Attached Figure Description

[0031] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0032] This embodiment discloses a card dispensing device with a self-locking structure, which is mainly used in interactive exhibition facilities and other scenarios that require automatic card dispensing. It aims to solve the problems of existing card dispensing devices having complex structures, internal sliders that scratch cards during return to their original position, and edge damage during card dispensing. The following provides a detailed description of the device in conjunction with its specific structure and working process.

[0033] like Figure 1-3 As shown, this card dispensing device comprises four core parts: a transmission mechanism 100, a card pushing mechanism 200, a self-locking slider 300, and a card placement mechanism 400. Each part works together mechanically to achieve stable pushing of the card 401 and reset of the card pushing mechanism 200.

[0034] The transmission mechanism 100 provides power and motion guidance for the entire device, including a chain drive section 110 and a linear limiting track 120 arranged in parallel at intervals. The chain drive section 110 can drive the chain links to rotate cyclically through an external drive component such as a motor. A specific chain link is defined as a positioning chain link, which is used to drive the subsequent components to turn. The linear limiting track 120 is a long strip guide rail used to limit the movement direction of the card 401 pushing mechanism 200.

[0035] Combined Figure 4-6 As shown, the card pushing mechanism 200 is located between the chain drive section 110 and the linear limiting track 120. It is the core component connecting the transmission and the card pushing action, and specifically includes:

[0036] The mounting groove 210 is longitudinally opened on one side near the chain drive section 110. Inside it is a sliding slider 211 that can slide up and down. The sliding slider 211 is coaxially fixed with the positioning chain link of the chain drive section 110 and moves synchronously with the positioning chain link.

[0037] The transmission component 220 is located on one side near the linear limiting rail 120 and is in clearance fit with the linear limiting rail 120. It can slide along the length of the rail to ensure that the card pushing mechanism 200 moves in a straight line.

[0038] The slider mounting part 230 is a hollow cavity located in the middle of the card pushing mechanism 200. A self-locking slider 300 is installed inside. Preferably, a ball guide rail is provided on its inner side wall (not shown in the figure). Those skilled in the art will understand that this can reduce the sliding friction of the self-locking slider 300. The top is provided with an inwardly protruding mounting limiting part 232 to restrict the self-locking slider 300 from disengaging.

[0039] The self-locking slider 300 is a key component for realizing the self-locking and unlocking functions of this card dispensing device. Its structure and mating relationship are as follows:

[0040] like Figure 7 As shown, its lower part is provided with an outwardly protruding mounting fitting part 340, which is clearance-fitted with the mounting limiting part 232 of the slider mounting part 230 to ensure that the self-locking slider 300 can only slide in the up and down direction without disengaging.

[0041] The heart-shaped limiting groove 310 is preferably symmetrically opened on both sides of the self-locking slider 300. The groove has two locking positions, an upper end point 311 and a lower end point 312, which are used to limit the state of the self-locking slider 300.

[0042] The structure of the self-locking slide bar 320 is as follows: Figure 8As shown, it passes through the mounting hole at the bottom of the slider mounting part 230. The structure includes a bottom connecting crossbar 321, two upward extending vertical bars 322 on both sides, and a top connecting crossbar 323 that bends at the top of the vertical bar toward the heart-shaped limiting slide groove 310. The length of the top connecting crossbar 323 is shorter than that of the bottom connecting crossbar 321, and its end extends into the heart-shaped limiting slide groove 310 and can slide along the groove.

[0043] The elastic element 231 is preferably a spring, with its two ends respectively embedded in the first mounting part 350 on the bottom surface of the self-locking slider 300 and the second mounting part 233 on the bottom surface of the slider mounting part 230. In its natural state, it can push the self-locking slider 300 to return to its original position. In its compressed state, it drives the self-locking slide bar 320 to slide along the heart-shaped limiting slide groove 310 through the elastic force.

[0044] The card pusher block 330 is located on the top of the self-locking slider 300 and protrudes upward. Its height is preferably 2 / 3 of the thickness of the card 401. Specifically, the height is greater than 1 / 2 of the thickness of the card 401 and less than or equal to the thickness of the card 401. The end face that contacts the card 401 is flat, which can increase the force-bearing area. It extends into the pusher slot 402 of the card placement mechanism 400 to push the card 401.

[0045] The card placement mechanism 400 is located above the card pushing mechanism 200 and is used to hold the cards 401 to be pushed. Its shape is not limited, and specifically includes:

[0046] A card pusher slot 402 is located at the center of the bottom and extends along the length of the straight limiting track 120, allowing the card pusher block 330 to pass through and slide.

[0047] The first limiting part 410 and the second limiting part 420 are respectively fixed at both ends of the card placement mechanism 400 along the length direction, defined as below the first end and the second end. The first limiting part 410 is near the first end and has a downwardly inclined first limiting slope 411; the second limiting part 420 is near the second end and has a downwardly inclined second limiting slope 421.

[0048] The self-locking slider 300 is provided with a first mating part and a second mating part. In this embodiment, the first mating part is a first mating inclined surface 301 that is adapted to the first limiting inclined surface 411, and the second mating part is a second mating inclined surface 302 that is adapted to the second limiting inclined surface 421. The self-locking slider 300 can be driven to slide downward by the abutment and compression between the inclined surfaces.

[0049] This device, through the cyclic rotation of the chain drive 110, drives the card pushing mechanism 200 to reciprocate along the linear limiting track 120, completing the cyclic action of pushing the card 401 from the first end to the second end and resetting to the first end to prepare to push the next card 401. The specific process is as follows:

[0050] 1. Initial state, card to be pushed at the first end.

[0051] Combination Figure 9 As shown, at this time, the positioning link is located at the rightmost end of the chain drive 110, and the steering slider 211 is in the upper position in the mounting groove 210; the self-locking slider 300 is pushed upward under the natural thrust of the spring, and the mounting mating part 340 abuts against the mounting limiting part 232 of the slider mounting part 230 to restrict its upward movement; the top connecting crossbar 323 of the self-locking slide bar 320 is located at the lower end point 312 of the heart-shaped limiting groove 310; the card pushing block 330 passes through the card pushing groove 402 and abuts against the lower surface of the bottommost card 401 in the card placement mechanism 400.

[0052] 2. Push card 401 from the first end to the second end.

[0053] like Figure 10 As shown, the chain drive unit 110 drives the positioning chain link to rotate counterclockwise, causing the steering slider 211 to move synchronously with the chain link. Then, the installation groove 210 pulls the card push mechanism 200, and the transmission component 220 guides and slides along the straight limit track 120. The whole slides along the straight limit track 120 towards the second end.

[0054] During this process, the card pusher block 330 is always in contact with the card 401 and pushes it to the second end; since the self-locking slide bar 320 is located at the lower end point 312 of the heart-shaped limiting slide groove 310, it is in a stable locked state, the spring remains in a natural state, the self-locking slider 300 does not slide up and down, the card pusher block 330 is in stable contact with the card 401, and because the end face of the pusher block is flat and the height is suitable, the edge of the card 401 is subjected to uniform force and there is no obvious damage.

[0055] 3. Reach the second end and trigger the unlocked state to turn.

[0056] Combination Figure 11 As shown, when the card 401 is pushed to the second end, the card pushing mechanism 200 continues to move to the second end with the chain drive part 110. At this time, the second mating slope 302 of the self-locking slider 300 contacts and presses against the second limiting slope 421 of the second limiting part 420.

[0057] The downward force generated by the compression causes the self-locking slider 300 to slide downward, and the spring is compressed, changing from the natural state to the compressed state; at the same time, the top connecting crossbar 323 of the self-locking slide bar 320 slides along the heart-shaped limiting slide groove 310 from the lower end point 312 to the upper end point 311 and locks; the card push block 330 moves down with the self-locking slider 300, disengaging from the card 401, and is located below the card push groove 402 to avoid scratching the lower surface of the card 401 during subsequent reset.

[0058] At this time, the positioning chain link moves to the leftmost end of the chain drive section 110, driving the steering slider 211 to slide from top to bottom in the mounting groove 210. The card pushing mechanism 200 completes the steering and prepares to reset to the first end.

[0059] 4. Reset from the second end to the first end.

[0060] The chain drive unit 110 continues to drive the positioning chain link to rotate counterclockwise, and the steering slider 211 moves with the positioning chain link toward the first end, driving the card pushing mechanism 200 to slide in the opposite direction along the linear limit track 120 and reset toward the first end.

[0061] During this process, the self-locking slide bar 320 remains at the upper end point 311 of the heart-shaped limiting slide groove 310, the spring is in a compressed state, and the card pusher block 330 is always located below the card pusher slot 402 and does not contact the card 401. Figure 12 As shown; because the inner side of the slider mounting part 230 is provided with a ball guide rail, the sliding friction between the self-locking slider 300 and the mounting part is greatly reduced, the movement is smoother, and the wear of the parts is reduced.

[0062] 5. Reach the first device and unlock it, then prepare for the next push notification.

[0063] When the card pushing mechanism 200 is reset to the first end, the first mating inclined surface 301 of the self-locking slider 300 contacts and presses against the first limiting inclined surface 411 of the first limiting part 410, generating a downward force to further compress the spring, which is then released after a brief compression.

[0064] Under the action of the spring force, the self-locking slider 300 slides upward, and the top connecting crossbar 323 of the self-locking slide bar 320 slides along the heart-shaped limiting slide groove 310 from the upper end point 311 to the lower end point 312 and locks; the card pusher block 330 moves upward with the self-locking slider 300, passes through the card pusher slot 402 again and abuts against the next card 401, as shown in the state. Figure 9 As shown; at the same time, the positioning link moves to the rightmost end of the chain drive section 110, driving the steering slider 211 to slide from below the mounting groove 210 to above, and the card pushing mechanism 200 completes the steering, preparing for the next push from the first end to the second end.

[0065] This embodiment achieves the following technical effects through the above structure and working process:

[0066] The self-locking structure, through the cooperation of the heart-shaped limiting slide groove 310 and the self-locking slide rod 320, ensures that the card pusher block 330 completely disengages from the card during the reset process, thus completely avoiding scratches on the lower surface of the card caused by the slider returning to its original position. The card pusher block 330 adopts a large flat surface design and is height-adapted to the card thickness, increasing the force-bearing area during card pushing and effectively reducing damage to the card edges. The ball bearing guide rail on the inner side of the slider mounting part 230 significantly reduces the sliding friction of the self-locking slider 300, and together with the stable elastic force of the spring, extends the service life of the device. The overall structure achieves automatic reciprocating motion through the mechanical cooperation of chain drive and inclined plane extrusion, eliminating the need for complex electronic control components, ensuring high stability, and making it suitable for pushing various types of card products.
