Description

Technical Field

[0001] The present invention relates to the technical field of escalators, and in particular to an up-and-down integrated shopping cart automatic escalator. Background Art

[0002] Shopping cart escalators have become popular in recent years. Shopping cart escalators are usually installed in shopping supermarkets and are often arranged in parallel with escalators. Escalators are used for up and down transportation of passengers, while shopping cart escalators are only used for up and down transportation of supermarket shopping carts. At present, the common shopping cart escalator conveying device uses a special special-shaped chain and a matching connecting device set on the shopping cart. The shopping cart can be connected to the chain, and then the chain is circulated up and down to drive the shopping cart to be transported up and down. Therefore, the shopping cart needs to be matched with the shopping escalator to be used. Conventional shopping carts are not universal, which will increase the procurement cost.

[0003] For example, the publication number "CN118239360A" discloses "a shopping cart escalator conveying system", including a truss, a rear wheel transport frame, a first chain, a driving assembly and a fixed assembly. The truss is provided with a guide rail, the first chain is slidably connected inside the guide rail, the first chain is connected to the driving assembly, the driving assembly is arranged inside the truss, the fixed assembly is connected to the first chain, and the rear wheel transport frame is connected above the truss; the fixed assembly includes a positioning block, and both ends of the first chain are rotatably connected to the positioning block. However, in actual applications, this type of device can only fix the rollers of the shopping cart, and because the shopping cart rollers can rotate and change direction, the fixing effect is not good, and different traction methods need to be used on the up and down escalators to overcome the movement tendency of the shopping cart in different directions. Summary of the invention

[0004] In view of the problem that the prior art mentioned in the background technology has poor fixing effect and different installation methods need to be adopted on up and down escalators, the present invention provides an up and down integrated shopping cart escalator, which improves the fixing effect of the shopping cart. At the same time, during installation, the same traction method can be adopted on the up and down escalators, thereby reducing production costs and being convenient for users to use.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions.

[0006] An up-and-down integrated shopping cart escalator, comprising: A traction track, wherein the traction track comprises an upward track and a downward track; A drive chain disposed on the traction track; A traction unit, wherein the traction unit is connected to a driving chain, and the traction unit is connected to a shopping cart; A rotating sleeve, which is arranged on the traction unit and is engaged and connected with a cross bar of the shopping cart; When the shopping cart is connected to the traction unit, the shopping cart can be rotated around the crossbar.

[0007] In the prior art, the method of driving the shopping cart to move by a drive chain is generally to set a mechanism capable of fixing the guide wheel of the shopping cart on the drive chain, so that when the shopping cart is displaced onto the drive chain, it can be fixed by the drive chain and then synchronously moved by the drive chain. However, in this type of driving device, the guide wheel of the shopping cart needs to be fixed, but the guide wheel of the shopping cart is a relatively movable component. In order to achieve stable fixation, the guide wheel of the shopping cart needs to be designed and matched accordingly. At that time, since there are four guide wheels of the shopping cart, in order to improve the uniformity of fixing the guide wheels of the shopping cart, two synchronously moving drive chains need to be set, which increases the cost. Moreover, since the driving force is connected to the guide wheel, but since the guide wheel is at a lower position and is far from the center of gravity of the shopping cart, the overall stability of the shopping cart is poor during use. Moreover, since the guide wheel can roll and rotate circumferentially, the connection stability between the guide wheel and the drive chain is poor, so there is a risk of protrusion during the driving process of the shopping cart, which is easy to cause greater damage. At the same time, the power direction of the shopping cart is different during the up and down process, that is, the movement trend of the shopping cart is different, so the connection relationship between the guide wheel and the drive chain needs to be set accordingly. Generally speaking, when the shopping cart goes up, the drive chain needs to press against the guide wheel from the back, and when the shopping cart goes down, the drive chain needs to press against the guide wheel from the front. Therefore, when setting up a two-way elevator, different drive chains need to be set accordingly. This increases the production cost.

[0008] In the present application, a drive chain is arranged on a traction track, wherein a drive member is arranged inside the traction track, and the drive chain can be driven to rotate by the drive member, and a traction unit is arranged on the drive chain, and the rotation of the drive chain can synchronously drive the traction unit to move. In the present application, the driving method of the drive chain for guiding the shopping cart is to rotatably connect with the cross bar on the shopping cart through the rotating sleeve on the traction unit, and drive the cross bar of the shopping cart to drive the overall movement of the shopping cart. Since the rotating sleeve is connected to the cross bar, only one drive chain is required during use, and the rotating sleeve on the drive chain is connected to the middle part of the cross bar, so that the drive chain can drive the shopping cart to move as a whole. This driving method can ensure the uniformity of traction of the shopping cart only by connecting to the middle part of the cross bar, thereby reducing the setting cost. Furthermore, since the cross bar can rotate in the rotating sleeve, the cross bar can be connected to the rotating sleeve at any angle, that is, when the shopping cart is in an upward tilting state or a downward tilting state, it can be connected to the rotating sleeve. Since the shopping cart can freely rotate relative to the rotating sleeve through the cross bar, it can adapt to the switching of the cross bar at different angles between ascending, leveling and descending. At the same time, since the rotating sleeve is a sleeve-shaped structure, the rotating sleeve is connected to the cross bar, and the rotating sleeve can wrap the cross bar. During the ascending process, the rotating sleeve can abut against the cross bar at different positions, and during the ascending process, the shopping cart can The shopping cart can be pulled upwards to provide a traction and lifting effect on the shopping cart; in the downward process, the downward movement tendency of the shopping cart can be limited by the rotating sleeve, providing a limit constraint effect on the shopping cart, thereby maintaining the synchronous movement of the shopping cart and the drive chain; therefore, in the upward and downward processes, the shopping cart can adapt to the inclination of the upward and downward slopes by rotating the cross bar, so that the traction tracks for the upward and downward directions only need to be set with the same specifications, thereby reducing the installation cost and making it easier for users to understand during use without having to consider the need to change the connection method between the shopping cart and the drive chain during the upward process.

[0009] Preferably, the drive chain includes a plurality of chain links, each of which is rotatably connected to each other, each of which includes a chain plate, and the traction unit is connected to the chain plate. The drive chain is divided into a plurality of chain links, and the plurality of chain links are rotatably connected to each other. The rotation of the chain links can realize the rotation effect of the drive chain, thereby ensuring that the drive chain can be connected to the driving member for cyclic rotation. Chain plates are provided on the chain links, and the traction unit is provided on the chain plates, so that the traction unit does not affect the mutual rotation between the chain links.

[0010] Preferably, the rotating sleeve includes a connecting opening, and the cross bar is connected to the rotating sleeve through the connecting opening. The connecting opening provided on the rotating sleeve can place the cross bar in the rotating sleeve, which facilitates the disconnection and connection of the cross bar.

[0011] Preferably, a travel track is provided on the side of the traction track, the traction unit is connected to the cross bar on the front side of the shopping cart, and the rear wheel of the shopping cart is in contact with the travel track. Since the traction track needs to stably pull the shopping cart, the traction track is provided in the middle of the entire shopping cart conveying track, so as to improve the uniformity of traction; therefore, travel tracks are also provided on both sides of the traction track, and the smoothness of the shopping cart traction can be improved by contacting the guide wheel of the shopping cart through the travel track. In the present application, the traction unit can be connected to the front cross bar of the shopping cart, or to the rear cross bar of the shopping cart. Preferably, in order to ensure the stability of the shopping cart and the convenience of disengagement and engagement of the shopping cart, the cross bar in front of the shopping cart is connected to the rotating sleeve, and the rear wheel of the shopping cart is connected to the travel track, so as to ensure the convenient operation of the shopping cart and the stability and smoothness of the travel on the track, and the guide wheel on the side of the cross bar connected to the rotating sleeve of the shopping cart can be in a suspended state, or can also be in contact with the travel track.

[0012] Preferably, the traction unit is provided with a locking unit, and the traction track includes an unlocking unit. When the cross bar is connected to the rotating sleeve, the locking unit locks the cross bar in the rotating sleeve. When the traction unit moves to the unlocking unit, the unlocking unit unlocks the locking unit, and the cross bar can escape from the rotating sleeve. Since the shopping cart is connected to the traction unit, and the cross bar is connected to the rotating sleeve through the connecting opening, it is necessary to lock the cross bar of the shopping cart to prevent the cross bar from escaping from the rotating sleeve during the operation of the shopping cart. At the same time, an unlocking unit is required, and the unlocking unit is provided at a specific position of the traction track, generally at the starting and ending positions of the traction track, so that when the shopping cart runs to this position, the locking unit can be unlocked by the unlocking unit, so that the cross bar of the shopping cart can escape from the connecting opening of the rotating sleeve.

[0013] Preferably, the locking unit includes a block member and a locking member, the block member includes a pressure rod and a shift rod, the locking member includes a lock rod and a shift rod, when the cross bar is connected to the rotating sleeve, the cross bar presses down the pressure rod, the pressure rod drives the shift rod to rotate, the shift rod is located above the cross bar, and the pressure rod is engaged with the lock rod. The unit includes a block member and a locking member, wherein the main function of the block member is to lock the cross bar on the shopping cart through the pressure rod and the shift rod. Furthermore, the stopper is rotatably connected to the traction unit, and the pressure rod and the shift rod are staggered and form an "L"-shaped structure. In the initial state, the pressure rod is located in the rotating sleeve and below the connecting opening, while the shift rod is not in the rotating sleeve. Therefore, when the cross bar is placed in the connecting sleeve, the cross bar will press down on the pressure rod, so that the pressure rod drives the stopper to rotate as a whole. Due to the squeezing of the cross bar, the pressure rod is rotated to a position disengaged from the rotating sleeve. Therefore, the shift rod is rotated to be inside the rotating sleeve and above the cross bar. At this time, since the rotating block is not in a limited position, the stopper does not have a locking and limiting function, so that in this state, the cross bar can still escape. The locking member includes a locking rod and a shifting rod, and the block member can be locked by the locking rod and the shifting rod, wherein the locking rod and the shifting rod are similar to the block member, and are arranged in an "L" shape, wherein the locking rod is located at the top and the shifting rod is located at the bottom. When the pressure rod rotates, it can be engaged and connected with the locking rod, so that the pressure rod can achieve an engagement and limiting effect through the locking rod, so that the cross bar can be fixed in the rotating sleeve, and the shifting rod is connected to the locking rod, and can drive the locking rod to rotate synchronously by shifting the shifting rod. After the locking rod rotates, the engagement connection between the locking rod and the pressure rod can be disengaged, thereby realizing unlocking. At this time, the pressure rod and the shifting rod can be adaptively rotated as the cross bar is disengaged.

[0014] Preferably, the unlocking unit includes a raised section arranged on the traction track. When the traction unit moves to the raised section, the raised section moves the lever, and the lever drives the lock rod to rotate. The pressure rod escapes from the lock rod to unlock, and the cross bar can escape from the rotating sleeve. In order to ensure the safety of the shopping cart during the traction process, the raised section is arranged at a specific position. The raised section is arranged at the starting and ending positions of the traction track, wherein the raised section is a part that is partially raised upward. Since the shopping cart needs to pass through the raised section when entering the traction track, and the direction of travel of the shopping cart is forward, during this process, the raised section will relatively generate a backward pushing force on the lever, thereby driving the lever to rotate, and then realizing the unlocking between the lock rod and the pressure rod.

[0015] Preferably, the raised section includes a starting section and an ending section, a leveling section is provided between the starting section and the ending section, and the starting section and the ending section are guide slopes that smoothly transition with the leveling section. Since the raised section is provided with a starting section and an ending section, and the starting section, the ending section and the leveling section are transitionally connected, an action of moving the lever can be generated through the starting section and the ending section, and since the raised section has a leveling section, after unlocking through the starting section, the lever continues to receive the moving effect of the leveling section on the leveling section, and on the leveling section, the lever is always moved away, so the lock rod is in a continuously unlocked state, thereby enabling the user to have sufficient time to separate the shopping cart from the traction unit in this area.

[0016] Preferably, the block member and the locking member are both rotatably connected to the locking unit, and elastic reset members are arranged between the block member and the locking member and the locking member unit. The elastic reset members arranged on the block member and the locking member can realize the automatic reset effect of the block member and the locking member, so that after the cross bar is separated from the rotating sleeve, the block member can be quickly reset by the elastic reset member, and then the pressure rod is reset to the rotating sleeve again, and the gear rod is separated from the rotating sleeve, so that the cross bar of the shopping cart can be smoothly engaged with the rotating sleeve next time; at the same time, the locking member can be driven to reset, and the locking rod can be rotated to a suitable position again, so that the next time the pressure rod can be engaged with the locking rod at a specific position.

[0017] Preferably, a locking block is provided on the locking rod, and when the pressure rod rotates downward, the pressure rod abuts against the locking block, and when the pressure rod rotates to the right position, the pressure rod is engaged with the locking block. A locking block is provided on the locking rod, wherein the locking block is provided on the side of the locking rod facing the pressure rod, the locking block is provided with an upward protrusion, and an inclined surface for convenient guidance is also provided on the locking block. Similarly, an inclined surface is also provided at the end of the pressure rod, so that the pressure rod can contact the inclined surface on the locking block through the inclined surface of the end during the rotation process and drive the locking rod to deflect slightly, so that the locking block can be moved downward, and then the smooth movement of the pressure rod can be ensured. Subsequently, when the pressure rod is separated from the locking block, the locking rod is reset again under the drive of the reset member, and the locking block is engaged with the pressure rod, and the pressure rod is restricted from resetting, so as to achieve a locking effect.

[0018] The beneficial effects of the present invention are as follows: (1) During the up and down process, the shopping cart can adapt to the up and down slope by rotating the cross bar, so that the up and down traction tracks only need to be set with the same specifications, thereby reducing the installation cost and making it easier for users to understand during use; (2) The locking unit and the unlocking unit are provided to ensure the connection stability between the shopping cart and the traction unit and prevent the shopping cart from being disengaged. At the same time, the unlocking unit at a specific position can quickly unlock the shopping cart and the traction unit to facilitate disengagement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Embodiment 1: like Figure 1 , 2 As shown in , 3, 4, and 5, an up-and-down integrated shopping cart escalator comprises: A traction track 1, the traction track 1 includes an upward track and a downward track; A drive chain 2 arranged on the traction track 1; A traction unit 3, wherein the traction unit 3 is connected to the driving chain 2, and the traction unit 3 is connected to the shopping cart 4; A rotating sleeve 31, wherein the rotating sleeve 31 is disposed on the traction unit 3, and the rotating sleeve 31 is engaged and connected with the cross bar 41 of the shopping cart 4; When the shopping cart 4 is connected to the traction unit 3 , the shopping cart 4 can rotate around the cross bar 41 .

[0031] In the prior art, the method of driving the shopping cart 4 to move by the driving chain 2 is generally to set a mechanism on the driving chain 2 that can fix the guide wheel of the shopping cart 4, so that when the shopping cart 4 is displaced onto the driving chain 2, it can be fixed by the driving chain 2, and then synchronously moved by the driving chain 2. However, in this type of driving device, the guide wheel of the shopping cart 4 needs to be fixed, but the guide wheel of the shopping cart 4 is a relatively movable component. In order to achieve stable fixation, it is necessary to make a corresponding design match for the guide wheel of the shopping cart 4. At that time, since the shopping cart 4 is provided with four guide wheels, in order to improve the uniformity of fixing the guide wheels of the shopping cart 4, two synchronously moving driving chains 2 are required, which increases the cost. In addition, since the driving force is connected to the guide wheel, but since the guide wheel is at a lower position and is far away from the center of gravity of the shopping cart 4, the overall stability of the shopping cart 4 is poor during use, and since the guide wheel can roll and rotate circumferentially, the connection stability between the guide wheel and the driving chain 2 is poor, so there is a risk of protrusion during the driving process of the shopping cart 4, which is easy to cause greater damage. At the same time, the power direction of the shopping cart 4 is different during the up and down process, that is, the movement trend of the shopping cart 4 is different, so it is necessary to set the connection relationship between the guide wheel and the drive chain 2 accordingly. Generally speaking, when the shopping cart 4 goes up, the drive chain 2 needs to press against the guide wheel from the back, and when the shopping cart 4 goes down, the drive chain 2 needs to press against the guide wheel from the front. Therefore, when setting a bidirectional elevator, different drive chains 2 need to be set accordingly, which increases the production cost.

[0032] In this embodiment, a driving chain 2 is arranged on the traction track 1, wherein a driving member is arranged inside the traction track 1, and the driving member can drive the driving chain 2 to rotate, and a traction unit 3 is arranged on the driving chain 2, and the rotation of the driving chain 2 can synchronously drive the traction unit 3 to move. In this embodiment, the driving mode of the driving chain 2 for guiding the shopping cart 4 is to rotatably connect with the cross bar 41 on the shopping cart 4 through the rotating sleeve 31 on the traction unit 3, and drive the overall movement of the shopping cart 4 by driving the cross bar 41 of the shopping cart 4. Since the rotating sleeve 31 is connected with the cross bar 41, only one driving chain 2 is required during use, and the rotating sleeve 31 on the driving chain 2 is connected with the middle part of the cross bar 41, so that the driving chain 2 can drive the shopping cart 4 to move as a whole. This driving mode can ensure the uniformity of traction of the shopping cart only by connecting with the middle part of the cross bar, thereby reducing the setting cost. Furthermore, since the cross bar 41 can rotate within the rotating sleeve 31, the shopping cart 4 can adapt to the up and down slope inclination by rotating the cross bar 41 during the up and down process, so that the up and down traction rails 1 only need to be set with the same specifications, thereby reducing the installation cost and making it easier for users to understand during use without having to consider the need to change the connection method between the shopping cart 4 and the drive chain 2 during the up process.

[0033] like Figure 4 As shown, the drive chain 2 includes a plurality of connections 21, each of the chain links is rotatably connected to each other, each connection 21 includes a chain plate 22, and the traction unit 3 is connected to the chain plate 22. The drive chain 2 is divided into a plurality of connections 21, and the plurality of connections 21 are rotatably connected. The rotation of the connection 21 can realize the rotation effect of the drive chain 2, thereby ensuring that the drive chain 2 can connect the drive member for cyclic rotation. The connection 21 is provided with a chain plate 22, and the traction unit 3 is provided on the chain plate 22, so that the traction unit 3 does not affect the mutual rotation between the various connections 21.

[0034] like Figure 4 As shown, the rotating sleeve 31 includes a connecting opening 32, and the cross bar 41 is connected to the rotating sleeve 31 through the connecting opening 32. The connecting opening 32 provided on the rotating sleeve 31 can place the cross bar 41 in the rotating sleeve 31, so as to facilitate the disconnection and connection of the cross bar 41.

[0035] like Figure 5As shown, a traveling track is arranged on the side of the traction track 1, the traction unit 3 is connected to the cross bar 41 on the front side of the shopping cart 4, and the rear wheel of the shopping cart 4 contacts the traveling track. Since the traction track 1 needs to stably tow the shopping cart 4, the traction track 1 is arranged in the middle of the entire track for conveying the shopping cart 4, so as to improve the uniformity of traction; therefore, traveling tracks are also arranged on both sides of the traction track 1, and the traveling tracks are in contact with the guide wheels of the shopping cart 4, so as to improve the smoothness of traction of the shopping cart 4. In this embodiment, the traction unit 3 can be connected to the front cross bar 41 of the shopping cart 4, and can also be connected to the rear cross bar 41 of the shopping cart 4. Preferably, in order to ensure the stability of the shopping cart 4 and the convenience of disengagement and engagement of the shopping cart 4, the front cross bar 41 of the shopping cart 4 is connected to the rotating sleeve 31, and the rear wheel of the shopping cart 4 is connected to the travel track, so as to ensure the convenient operation of the shopping cart 4 and the stability and smoothness of the travel on the track, and the guide wheel on the side of the cross bar connected to the rotating sleeve 31 of the shopping cart 4 can be in a suspended state or can also be in contact with the travel track.

[0036] Through the above-mentioned structural features, this embodiment can adapt the shopping cart to the up and down slope inclination by rotating the cross bar during the up and down process, so that the up and down traction tracks only need to be set to the same specifications, thereby reducing the installation cost and making it easier for users to understand during use.

[0037] Embodiment 2: like Figure 6 , 8 As shown, different from Example 1, in this embodiment, a locking unit 33 is provided on the traction unit 3, and the traction track 1 includes an unlocking unit 34. When the cross bar 41 is connected to the rotating sleeve 31, the locking unit 33 locks the cross bar 41 in the rotating sleeve 31. When the traction unit 3 moves to the unlocking unit 34, the unlocking unit 34 unlocks the locking unit 33, and the cross bar 41 can escape from the rotating sleeve 31. Since the shopping cart 4 is connected to the traction unit 3, and the cross bar 41 is connected to the rotating sleeve 31 through the connecting opening 32, it is necessary to lock the cross bar of the shopping cart 4 to prevent the cross bar from being disengaged from the rotating sleeve 31 during the operation of the shopping cart 4. At the same time, an unlocking unit 34 is required, and the unlocking unit 34 is arranged at a specific position of the traction track 1, generally at the starting and ending positions of the traction track 1, so that when the shopping cart 4 runs to this position, the locking unit 33 can be unlocked by the unlocking unit 34, so that the cross bar 41 of the shopping cart 4 can be disengaged from the connecting opening 32 of the rotating sleeve 31.

[0038] like Figure 6 , 7As shown, the locking unit 33 includes a block member 35 and a locking member 36, the block member 35 includes a pressure rod 351 and a shift rod 352, the locking member 36 includes a locking rod 361 and a shift rod 362, when the cross bar 41 is connected to the rotating sleeve 31, the cross bar 41 presses down the pressure rod 351, the pressure rod 351 drives the shift rod 352 to rotate, the shift rod 352 is located above the cross bar 41, and the pressure rod 351 is engaged with the locking rod 361. The unit includes the block member 35 and the locking member 36, wherein the main function of the block member 35 is to lock the cross bar 41 on the shopping cart 4 through the pressure rod 351 and the shift rod. The locking member 351 is in an L-shaped configuration and the locking member 352 is in an L-shaped configuration. The locking member 36 is also provided, wherein the locking member 36 includes a locking rod 361 and a lever 362, through which the block member 35 can be locked, wherein the locking rod 361 and the lever 362 are also similar to the block member 35, in an "L"-shaped arrangement, wherein the locking rod 361 is located at the top, and the lever 362 is located at the bottom, and when the pressure rod 351 is rotated, it can be engaged with the locking rod 361, so that the pressure rod 351 can be engaged and limited by the locking rod 361, so that the cross bar 41 can be fixed in the rotating sleeve 31, and the lever 362 is connected to the locking rod 361, and can drive the locking rod 361 to rotate synchronously by toggling the lever 362, and when the locking rod 361 is rotated, the engagement connection between the locking rod 351 and the pressure rod 351 can be disengaged, thereby realizing unlocking, at this time, the pressure rod 351 and the lever 352 can be adaptively rotated as the cross bar 41 is disengaged.

[0039] like Figure 8 , 9As shown, the unlocking unit 34 includes a raised section 5 arranged on the traction track 1. When the traction unit 3 moves to the raised section 5, the raised section 5 moves the lever 362, and the lever 362 drives the lock rod 361 to rotate, and the pressure rod 351 escapes from the lock rod 361 to unlock, and the cross bar can escape from the rotating sleeve 31. In order to ensure the safety of the shopping cart 4 during the traction process, the raised section 5 is set at a specific position, and the raised section 5 is set at the starting and ending positions of the traction track 1, wherein the raised section 5 is a part that is partially raised upward. Since the shopping cart 4 needs to pass through the raised section 5 when entering the traction track 1, and the direction of travel of the shopping cart 4 is forward, in this process, relatively, the raised section 5 will generate a backward pushing force on the lever 362, thereby driving the lever 362 to rotate, and then realizing the unlocking between the lock rod 361 and the pressure rod 351.

[0040] like Fig. 9 As shown, the raised section 5 includes a starting section 51 and an ending section 52, and a leveling section 53 is provided between the starting section 51 and the ending section 52. The starting section 51 and the ending section 52 are guide slopes 54 that smoothly transition with the leveling section 53. Since the raised section 5 includes the starting section 51 and the ending section 52, and the starting section 51, the ending section 52 and the leveling section 53 are transitionally connected, an action of moving the lever 362 can be generated through the starting section 51 and the ending section 52, and since the raised section 5 has the leveling section 53, after unlocking through the starting section 51, on the leveling section 53, the lever 362 still continues to receive the moving effect of the leveling section 53, and on the leveling section 53, the lever 362 is always moved away, so the lock rod 361 is in a continuously unlocked state, so that the user can have sufficient time to separate the shopping cart 4 from the traction unit 3 in this area.

[0041] like Figure 7 As shown, the block member 35 and the locking member 36 are both rotatably connected to the locking unit 33, and an elastic reset member 37 is arranged between the block member 35 and the locking member 36 and the locking member 36 unit. In this embodiment, the elastic reset member 37 is a torsion spring. The elastic reset member 37 arranged on the block member 35 and the locking member 36 can realize the automatic reset effect of the block member 35 and the locking member 36, so that after the cross bar 41 is separated from the rotating sleeve 31, the block member 35 can be quickly reset by the elastic reset member 37, and then the pressure rod 351 is reset to the rotating sleeve 31 again, and the gear rod 352 is separated from the rotating sleeve 31, so that the cross bar 41 of the shopping cart 4 can be smoothly engaged with the rotating sleeve 31 next time; at the same time, the locking member 36 can be driven to reset, and the locking rod 361 is rotated to a suitable position again, so that the next time the pressing rod 351 can be engaged with the locking rod 361 at a specific position.

[0042] like Figure 7 As shown, a locking block 363 is provided on the locking rod 361 . When the pressing rod 351 rotates downward, the pressing rod 351 abuts against the locking block 363 . When the pressing rod 351 rotates to the right position, the pressing rod 351 is engaged and connected with the locking block 363 . A locking block 363 is provided on the locking rod 361, wherein the locking block 363 is arranged on the side of the locking rod 361 facing the pressure rod 351, the locking block 363 is protruding upward, and a slope for convenient guidance is also provided on the locking block 363.

Subsequently, when the pressure rod 351 is separated from the locking block 363, the locking rod 361 is reset again under the drive of the reset member, and is engaged and connected with the pressure rod 351 through the locking block 363, and the pressure rod 351 is restricted from resetting, thereby achieving a locking effect.

[0043] This embodiment provides a locking unit and an unlocking unit to ensure the connection stability between the shopping cart and the traction unit and prevent the shopping cart from being disengaged. At the same time, the unlocking unit at a specific position can quickly unlock the shopping cart and the traction unit to facilitate disengagement.

[0044] This embodiment also includes: A traction track 1, the traction track 1 includes an upward track and a downward track; A drive chain 2 arranged on the traction track 1; A traction unit 3, wherein the traction unit 3 is connected to the driving chain 2, and the traction unit 3 is connected to the shopping cart 4; A rotating sleeve 31, wherein the rotating sleeve 31 is disposed on the traction unit 3, and the rotating sleeve 31 is engaged and connected with the cross bar 41 of the shopping cart 4; When the shopping cart 4 is connected to the traction unit 3, the shopping cart 4 can rotate around the cross bar 41; The driving chain 2 includes a plurality of links 21, each of the chain links is rotatably connected to each other, each link 21 includes a chain plate 22, and the traction unit 3 is connected to the chain plate 22; The rotating sleeve 31 includes a connecting opening 32, and the cross bar 41 is connected to the rotating sleeve 31 through the connecting opening 32; A traveling track is arranged on the side of the traction track 1, the traction unit 3 is connected to the cross bar 41 on the front side of the shopping cart 4, and the rear wheels of the shopping cart 4 are in contact with the traveling track.

[0045] In this embodiment, a driving chain 2 is arranged on the traction track 1, wherein a driving member is arranged inside the traction track 1, and the driving member can drive the driving chain 2 to rotate, and a traction unit 3 is arranged on the driving chain 2, and the rotation of the driving chain 2 can synchronously drive the traction unit 3 to move. In this embodiment, the driving mode of the driving chain 2 for guiding the shopping cart 4 is to rotatably connect with the cross bar 41 on the shopping cart 4 through the rotating sleeve 31 on the traction unit 3, and drive the overall movement of the shopping cart 4 by driving the cross bar 41 of the shopping cart 4. Since the rotating sleeve 31 is connected with the cross bar 41, only one driving chain 2 is required during use, and the rotating sleeve 31 on the driving chain 2 is connected with the middle part of the cross bar 41, so that the driving chain 2 can drive the shopping cart 4 to move as a whole. This driving mode can ensure the uniformity of traction of the shopping cart only by connecting with the middle part of the cross bar, thereby reducing the setting cost. Furthermore, since the crossbar 41 can rotate in the rotating sleeve 31, the shopping cart 4 can adapt to the slope of the up and down directions by rotating the crossbar 41 during the up and down processes, so that the traction rails 1 for the up and down directions only need to be set with the same specifications, thereby reducing the installation cost, and at the same time, it can make it easier for users to understand during use without having to consider the need to change the connection method between the shopping cart 4 and the drive chain 2 during the up process. The drive chain 2 is divided into a plurality of connections 21, and the plurality of connections 21 are rotationally connected. The rotation software of the connection 21 can realize the rotation effect of the drive chain 2, thereby ensuring that the drive chain 2 can connect the drive member for cyclic rotation. A chain plate 22 is provided on the connection 21, and the traction unit 3 is provided on the chain plate 22, so that the traction unit 3 does not affect the mutual rotation between the various connections 21. The connection opening 32 provided on the rotating sleeve 31 can place the crossbar 41 in the rotating sleeve 31, which is convenient for the disengagement and connection of the crossbar 41. Since the traction track 1 needs to stably pull the shopping cart 4, the traction track 1 is set in the middle of the entire track for conveying the shopping cart 4, so as to improve the uniformity of traction; therefore, traveling tracks are also set on both sides of the traction track 1, and the smoothness of traction of the shopping cart 4 can be improved by contacting the guide wheels of the shopping cart 4 through the traveling tracks. In this embodiment, the traction unit 3 can be connected to the front cross bar 41 of the shopping cart 4, or it can be connected to the rear cross bar 41 of the shopping cart 4.
