Description

The structure of the shopping cart coin lock

technical field

The utility model relates to machinery, in particular to a structure of a coin-operated lock for a shopping cart, especially a structure of a coin-operated lock for a shopping cart that strengthens the stability of the coin-operated lock for holding coins.

Background technique

A hypermarket is a place where consumers can buy enough daily necessities or food at one time in a busy modern life. Since most consumers will buy a large amount of supplies or food at a time, it must be carried by a shopping cart. There are many consumers in the store, so it is quite difficult to manage the shopping cart. In view of this, the coin lock is used to manage the homing method of the shopping cart, so as to achieve the purpose of management. As shown in Figure 1, it is the structure of the existing shopping cart coin lock. This structure mainly uses an eccentric method to fix the position of the coin, and then achieves the locking plate 3 to be fixed or disengaged. When the coin 2 is placed in the coin lock 1, The free fixing part 12 on the seat body 10 will be squeezed by the coin 2 and clamped towards the direction of the coin 2, while the coin 2 will be resisted by the fixed positioning part 14 provided at the corresponding free fixing part 12, and the free fixing part 12 can control the hook 16 to fix or disengage the locking plate 3, and then achieve the purpose of allowing the shopping carts to be managed in series. However, this kind of structure uses an eccentric manner as the means for fixing the coin 2, so it is very weak in the stability of the holding of the coin 2, and the coin 2 can be taken out in a destructive manner only by applying force, and this structure will cause Misplaced shopping carts.

Detailed ways

As shown in accompanying drawing 2 and accompanying drawing 3, it is the three-dimensional schematic diagram and the three-dimensional exploded schematic diagram of the preferred embodiment of the utility model, it can be clearly seen from the figure that the coin lock 4 is fixed on the cart handle 6 by using the lower housing 50 upper, and the upper housing 52 and the lower housing 50 are mutually locked, and the upper housing 52 is provided with a hole 520 for the insertion of the locking piece 7 at a predetermined position, and the coin lock 4 is mainly composed of the base 40, the fastener 42, sliding seat 44, and linkage rod 46, wherein the base 40 is provided with a groove 402 with a first fixing part 404 at a predetermined position, and adjacent to the groove 402 are respectively provided with a set of slide rails 406 and a A third fixing part 408 is set, and a corresponding track 409 is formed away from the groove 402, and the fastener 42 with the fixing part 422 is arranged in the groove 402 for fixing the locking piece 7, and the fastener 42 A second fixing portion 420 corresponding to the first fixing portion 404 is formed, and a first elastic member 8 is connected between the first fixing portion 404 and the second fixing portion 420 .

In addition, a hook 440 extending from a bottom surface of the sliding seat 44 is in contact with the slide rail 406 so that the sliding seat 44 can slide corresponding to the base 40 , and two extension arms 442 are provided on the sliding seat 44 , and a fourth fixing part 444 corresponding to the third fixing part 408 is formed at one end of each extension arm 442, and the third fixing part 408 and the fourth fixing part 444 are connected by the second elastic member 9, and the sliding The predetermined wall surface of seat 44 then extends two pivot joints 446, thus pivot joint 446 can allow linking rod 46 to be pivotally positioned, and each linking bar 46 forms a corresponding arc portion 460 at the other end, and connects The moving rod 46 is provided with a positioning member 462 at the end of the arc portion 460 to engage with the track 409 formed on the base 40 , and the track 409 has a corresponding inclination angle.

A sleeve 48 is provided between the arcs 460 formed by the linkage rod 46 , and the coin 2 is inserted through the socket 480 formed on the sleeve 48 .

By above-mentioned structure, composition design, with regard to the use situation of the present utility model, description is as follows, as shown in accompanying drawing 4 to accompanying drawing 6, it is the utility model to take out the use status schematic diagram 1 to 3 of locking plate, can clearly see from the figure , when the consumer wants to get the shopping cart, he can insert the coin 2 through the socket 480 formed on the casing 48 , and the coin 2 will be placed on the corresponding arc 460 on the linkage rod 46 at this time.

When applying force to the coin 2, the linkage rod 46 will be pushed inward, and the positioning part 462 on the linkage rod 46 will move along the track 409. Since the track 409 is at a corresponding inclination angle, the linkage rod 46 It will shrink inwards to clamp the coins 2. At the same time, the linkage rod 46 will retreat and drive the overall sliding seat 44, because the hook 440 on the sliding seat 44 will be in contact with the slide rail 406 on the base 40. Therefore, the sliding seat 44 will move backward synchronously, and the fastener 42 that was originally supported by the sliding seat 44 will be moved by the first elastic member 8 provided between the first fixing part 404 and the second fixing part 420. Pushing to make the fastener 42 rotate downwards, at this time, the second elastic member 9 provided between the fourth fixed part 444 at one end of the extension arm 442 and the third fixed part 408 on the base 40 will be compressed, and the above-mentioned The action of each component can make the locking piece 7 detach from the fixing part 422 on the buckle 42 smoothly and be taken out.

As shown in accompanying drawing 7 to accompanying drawing 9, it is the schematic diagram 1 to 3 of the use status of inserting the locking piece of the present utility model, can clearly see from the figure, when the consumer wants to return the shopping cart and take out the coin 2 inserted in it originally , insert the locking piece 7 into the hole 520 of the upper casing 52, at this time the locking piece 7 will push against the fastener 42, and the fastener 42 will compress the first elastic member 8, and the fixing piece 422 on the fastener 42 will be in contact with the fastener 42. Locking plate 7 phases are fixed.

At the same time of the above-mentioned operation process, because the fastener 42 rotates upwards, the compressed second elastic member 9 gets power to release the sliding seat 44, so that the sliding seat 44 moves forward, and at the same time the linkage rod on the sliding seat 44 46 also moves forward synchronously, and the locating member 462 on the linkage rod 46 will move again along the track 409 (as accompanying drawing 3), and make the corresponding arc portion 460 expand outwards, to loosen coin 2, Because the connecting rod 46 moves forward and can withstand the coins 2 to make it stack outwards, the consumer can get the originally inserted coins 2 smoothly at this moment.

Through the above overall structural description, it can be clearly understood that the utility model mainly uses the corresponding clamping method of the linkage rod 46 to effectively strengthen the clamping stability of the coin.
