Description

Technical Field

[0001] This utility model relates to the field of shopping basket technology, specifically to an adjustable pull rod shopping basket. Background Technology

[0002] As people's living standards improve, they are no longer satisfied with just the items themselves when shopping in supermarkets; they also seek comfort during the shopping process. A shopping basket is a container used to hold purchased items, essentially serving as a storage solution. As an indispensable accessory, the requirements for shopping baskets go beyond aesthetics; they also emphasize comfort and convenience.

[0003] The handles of existing pull-rod shopping baskets are directly fixed to the basket by threaded connection or riveting, and their height and comfortable push-pull angle cannot be adjusted. When stacking items, the handles will hinder stacking. At the same time, shoppers need to bend over repeatedly to take out items from the shopping basket during checkout, which increases the shoppers' labor costs and affects the shopping experience. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable pull rod shopping basket.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable pull-rod shopping basket includes a movable base. Four casters are fixedly mounted at the four corners of the bottom of the movable base. Fixed plates are symmetrically fixed at the front and rear ends of the right side of the movable base. A movable groove is formed on the left side of the fixed plate, and a slider is movably mounted in the movable groove. A connecting block is fixedly mounted at the end of the slider away from the fixed plate, and a shopping basket is fixedly mounted at the end of the connecting block away from the slider. A movable groove is formed on the right side of the fixed plate, and a first mounting block is fixedly mounted at the bottom of the movable groove. A first fixed block is rotatably connected to the first mounting block, and the first fixed block is rotatably connected to the first mounting block away from the first mounting block. A push rod is fixedly installed at one end of the block, and a second mounting block is movably installed at the upper end of the movable groove. A second fixed block is rotatably connected to the second mounting block. A support rod is fixedly installed at the end of the second fixed block away from the second mounting block. The end of the support rod away from the second fixed block is rotatably connected to the push rod. Through slots are opened on the left and right sides of the end of the second mounting block near the fixed plate. A spring is movably installed in the through slot. A limit post is movably installed at the open end of the through slot. Limit holes are evenly opened at the front and rear ends of the right side of the fixed plate. The outward end of the limit post is movably inserted into the limit hole.

[0007] Preferably, a synchronous motor is fixedly installed on the bottom right side of the movable base, and a coupling is fixedly installed on the output end of the synchronous motor. The synchronous motor is fixedly connected to a lead screw through the coupling. A guide rod is fixedly installed on the rear end of the upper right side of the movable base. The front connecting block is threaded onto the circumferential surface of the lead screw, and the rear connecting block is movably sleeved on the circumferential surface of the guide rod. By starting the synchronous motor fixedly installed on the bottom right side of the movable base, the synchronous motor drives the lead screw to rotate through the coupling. Then, during the rotation of the lead screw, it moves the connecting block along the movable groove. At the same time, the connecting block moves the shopping basket up and down during the movement, making it easier and more convenient for shoppers to take out the items from the shopping basket during the checkout process, thus reducing the labor costs for shoppers.

[0008] Preferably, the height of the lead screw is greater than the height of the moving groove; this prevents the connecting block from falling off the lead screw when it moves with the connecting block, thus affecting the use of the shopping basket.

[0009] Preferably, the cross-sectional dimensions of the moving groove are the same as those of the slider; this reduces the gap between the moving groove and the slider, allowing the slider to move more stably with the connecting block in the moving groove, thereby preventing the shopping basket from shaking significantly and allowing the shopping basket to rise and fall more stably.

[0010] Preferably, the upper circumferential surface of the push rod is provided with anti-slip texture; this can increase the friction between the push rod and the shopper, allowing the shopper to move the movable seat more stably by pulling the push rod.

[0011] Preferably, the diameter of the limiting post is the same as the diameter of the limiting hole; this reduces the gap between the limiting post and the limiting hole, allowing the limiting post to more stably fix the second mounting block in the movable groove, and allowing the push rod to stably pull the moving seat and shopping basket to move.

[0012] In view of this, compared with the prior art, the beneficial effects of this utility model are:

[0013] (i) In this application, when a shopper needs to adjust the shopping handle during the shopping process, they can press the limiting post inward to move the second mounting block, which in turn moves the limiting post to different limiting holes. This allows the limiting post to fix the second mounting block in different positions. Then, during the movement, the second mounting block moves along with the support rod via the second fixing block. The support rod then rotates around the first mounting block with the push rod, thereby adjusting the angle between the push rod and the fixing plate. This allows the push rod to move to a position that is convenient for the shopper to use, improving the shopper's shopping experience.

[0014] (ii) In this application, by starting the synchronous motor fixedly installed on the bottom right side of the movable seat 1, the synchronous motor drives the lead screw to rotate through the coupling. Then, during the rotation of the lead screw, the connecting block moves along the moving groove. At the same time, the connecting block moves the shopping basket up and down during the movement, so that shoppers can more easily and conveniently take out the items from the shopping basket during the checkout process, reducing the labor costs of shoppers.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The present invention provides the following embodiments:

[0022] An adjustable pull-rod shopping basket includes a movable base 1, with casters 2 fixedly mounted at the four corners of the bottom of the movable base 1. Fixed plates 6 are symmetrically fixedly mounted at the front and rear ends of the right side of the movable base 1. A movable groove 7 is formed on the left side of the fixed plate 6, and a slider 8 is movably mounted in the movable groove 7. A connecting block 9 is fixedly mounted at the end of the slider 8 away from the fixed plate 6, and a shopping basket 10 is fixedly mounted at the end of the connecting block 9 away from the slider 8. A movable groove 11 is formed on the right side of the fixed plate 6, and a first mounting block 12 is fixedly mounted at the bottom of the movable groove 11. A first fixed block 13 is rotatably connected to the first mounting block 12. A push rod 14 is fixedly installed at the end of the first fixed block 13 away from the first mounting block 12. A second mounting block 15 is movably installed at the upper end of the movable groove 11. A second fixed block 16 is rotatably connected to the second mounting block 15. A support rod 17 is fixedly installed at the end of the second fixed block 16 away from the second mounting block 15. The end of the support rod 17 away from the second fixed block 16 is rotatably connected to the push rod 14. The two ends of the second mounting block 15 near the fixed plate 6 are connected to each other. A through groove 18 is provided on the side, and a spring 19 is movably installed in the through groove 18. A limit post 20 is movably installed at the open end of the through groove 18. Limit holes 21 are evenly provided at both the front and rear ends of the right side of the fixing plate 6. The outward end of the limit post 20 is movably inserted into the limit hole 21. When a shopper needs to adjust the shopping handle during shopping, they can press the limit post 20 inward to compress the spring 19. Then, the second mounting block 15 is moved to move the limit post 20 to different positions of the limit hole 21. Then, under the reaction force of the spring 19, the limiting post 20 is inserted into the limiting hole 21 at different positions to fix the second mounting block 15. Then, during the movement, the second mounting block 15 moves along the support rod 17 via the second fixing block 16. Then, the support rod 17 rotates around the first mounting block 12 along with the push rod 14 to adjust the angle between the push rod 14 and the fixing plate 6, so that the push rod 14 can be moved to a position that is convenient for shoppers to use, thereby improving the shopping experience.

[0023] Specifically, a synchronous motor 3 is fixedly installed on the bottom right side of the movable seat 1. A coupling is fixedly installed on the output end of the synchronous motor 3. The synchronous motor 3 is fixedly connected to a lead screw 4 through the coupling. A guide rod 5 is fixedly installed on the rear end of the right side of the upper surface of the movable seat 1. A front connecting block 9 is threadedly connected to the circumferential surface of the lead screw 4, and a rear connecting block 9 is movably sleeved on the circumferential surface of the guide rod 5. By starting the synchronous motor 3 fixedly installed on the bottom right side of the movable seat 1, the synchronous motor 3 drives the lead screw 4 to rotate through the coupling. Then, during the rotation of the lead screw 4, the connecting block 9 moves along the movable groove 7, and at the same time, the connecting block 9 moves the shopping basket 10 up and down.

[0024] Specifically, the height of the lead screw 4 is greater than the height of the moving groove 7; by making the height of the lead screw 4 greater than the height of the moving groove 7, the connecting block 9 can be prevented from falling off the lead screw 4 when the lead screw 4 moves with the connecting block 9.

[0025] Specifically, the cross-sectional dimensions of the moving groove 7 are the same as those of the slider 8. By making the cross-sectional dimensions of the moving groove 7 and the slider 8 the same, the gap between the moving groove 7 and the slider 8 can be reduced, thereby allowing the slider 8 to move more stably with the connecting block 9 in the moving groove 7.

[0026] Specifically, the upper circumferential surface of the push rod 14 is provided with anti-slip texture; by providing anti-slip texture on the upper circumferential surface of the push rod 14, the friction between the push rod 14 and the shopper can be increased, allowing the shopper to move the movable seat 1 more stably by pulling the push rod 14.

[0027] Specifically, the diameter of the limiting post 20 is the same as the diameter of the limiting hole 21. By making the diameter of the limiting post 20 the same as the diameter of the limiting hole 21, the gap between the limiting post 20 and the limiting hole 21 can be reduced, thereby allowing the limiting post 20 to more stably fix the second mounting block 15 in the movable groove 11.

[0028] The working principle of this utility model is as follows: When a shopper needs to adjust the shopping handle during shopping, they press the limiting post 20 inward, causing it to compress the spring 19. Then, the second mounting block 15 moves the limiting post 20 to different positions of the limiting hole 21. Under the reaction force of the spring 19, the limiting post 20 inserts into the limiting hole 21 at different positions, thus fixing the second mounting block 15. During this movement, the second mounting block 15 moves along the support rod 17 via the second fixing block 16. The support rod 17 then moves around the first mounting block 12 along with the push rod 14. The push rod 14 is rotated to adjust the angle between it and the fixed plate 6, allowing the push rod 14 to move to a position convenient for shoppers. Then, the synchronous motor 3, which is fixedly installed on the right side of the bottom of the moving base 1, is activated, causing the synchronous motor 3 to drive the lead screw 4 to rotate through the coupling. During the rotation of the lead screw 4, the connecting block 9 moves along the moving groove 7, and the connecting block 9 moves up and down, causing the shopping basket 10 to rise and fall. This makes it easier and more convenient for shoppers to take out the items from the shopping basket 10 during the checkout process, reducing the shoppers' labor costs and improving their shopping experience.
