Description

Technical Field

[0001] The utility model relates to a carrier, in particular to a one-key lifting and folding carrier. Background Art

[0002] Carriers are also known as shopping baskets or bassinets in daily life and can be used as shopping baskets, bathtubs, for carrying pets, or as baby cribs, etc. For easy carrying and storage, carriers generally need to be folded, unfolded when in use, and folded when not in use.

[0003] Therefore, before this application, a liftable fence and a foldable basket (Patent No.: 202322008879.1) were designed. In the above structure, the upper enclosure pipe and the bottom frame are connected by a scissor-type folding mechanism to achieve folding. However, during the unlocking process, it needs to be realized by sliding a sliding sleeve on the upper enclosure pipe. But there is a surrounding cloth on the entire fence, and there is a cloth sleeve at the edge of the surrounding cloth. The cloth sleeve is sleeved on the upper enclosure pipe to install the surrounding cloth. Therefore, when the sliding sleeve slides on the upper enclosure pipe, it is easy to get stuck with the cloth sleeve or pull each other, resulting in unsmooth sliding.

[0004] To solve the above problems, this application newly designs a one-key lifting and folding carrier to solve them. Content of the Utility Model

The embodiments of the present disclosure can be executed independently of each other, or can be executed together in a mutually dependent relationship.

[0032] Referring to Figures 1 to 7 , the present utility model discloses a one-key lifting type folding carrier. The main structure of this application is composed of an upper frame body, a folding link mechanism 4, and a bottom frame 2. The upper frame body can be folded tightly against the bottom frame 2 through the folding link mechanism 4, thereby saving space. The upper frame body includes an upper perimeter tube 1, an unlocking member 7, and a perimeter tube connecting member 5. The folding link mechanism includes a sliding connecting member 3. The folding link mechanism has the same structure as that previously applied by our company, and is mainly composed of two cross-hinged links 4. The sliding connecting member 3 is hinged to the end of the link 4. Therefore, the above specific structure will not be described in detail.

[0033] As shown in the figure, the upper frame body is formed by inserting and screwing two oppositely arranged upper perimeter tubes 1 and perimeter tube connecting members 5. The upper perimeter tube 1 is provided with a chute 6 and a locking structure. In this application, the chute 6 is preferably a T-shaped groove. The sliding connecting member 3 is slidably matched with the chute 6. Of course, the sliding connecting member 3 is provided with a T-shaped block structure that cooperates with the T-shaped groove, and the sliding connecting member 3 can be locked by the locking structure and cannot slide along the chute 6. The unlocking member 7 is connected to the locking structure to realize the unlocking of the locking structure. A card slot 8 is provided on the side wall of the upper perimeter tube 1 and a perimeter rod (not shown in the figure) is clamped in the card slot 8. A perimeter cloth (not shown in the figure) is connected to the perimeter rod. The upper edge of the perimeter cloth is connected to the perimeter rod, and the lower edge of the perimeter cloth is connected to the bottom frame body, thereby wrapping the main structure to form a specific open basket.

[0034] For the convenience of operation, the unlocking member 7 is located on both sides of the upper frame body. Therefore, the unlocking member 7 needs to be connected to the locking structure through a steel wire rope 9.

[0035] As shown in the figure, the locking structure includes a clamping hole 10, a guide rod 11, a locking block 12, a fixed block 13 and a slider 14 provided on the sliding connecting member 3. The fixed block 13 is the part where the pipe connecting member 5 is inserted into the upper pipe 1. The locking block 12 is a square plate and is provided with a rod hole 15. The fixed block 13 is provided with a first guide hole 16, and the slider 14 is provided with a second guide hole 17. The guide rod 11 is located in the rod hole 15, the first guide hole 16 and the second guide hole 17, and the unlocking member 7 is connected to the slider 14 through a steel wire rope 9 and can pull the slider 14 to move, so that the first guide hole 16 and the second guide hole 17 drive the guide rod 11 to lift and lower, so that the locking block 12 is clamped into or disengaged from the clamping hole 10. As a preferred structure, the second guide hole 17 is an inclined long hole, and the first guide hole 16 is a vertical long hole. The working principle of the above structure is as follows: when folding is required, the unlocking member 7 pulls the slider 14 to move through the steel wire rope 9. While the slider 14 is moving, it squeezes the guide rod 11 through the second guide hole 17 and moves relative to the guide rod 11. The guide rod 11 can move vertically along the first guide hole 16 through the extrusion of the second guide hole 17, so as to drive the locking block 12 to move vertically and disengage from the clamping hole 10 to realize unlocking.

[0036] The slider 14 is provided with an inner groove 18, and both the bottom surface and the top surface of the inner groove 18 communicate with the outside. An avoidance opening 19 communicating with the inner groove 18 is provided on the end wall of the inner groove 18. The fixed block 13 passes through the avoidance opening 19 and is located in the inner groove 18. The fixed block 13 is provided with a convex block 20, and a return spring 21 is provided between the convex block 20 and the end wall. Through the return spring 21, we can realize automatic locking, and the locking process is the same as the unlocking process, except that the slider 14 moves in the opposite direction to the unlocking movement through the push of the return spring 21, so as to drive the locking block 12 to move vertically and insert into the clamping hole 10. Of course, during the unlocking process, the movement of the slider 14 will squeeze the return spring 21.

[0037] As shown in the figure, as a specific installation structure, a partition plate 22 is provided in the upper pipe 1, so as to divide the internal space of the upper pipe 1 into an installation hole 23 and the chute 6. The locking structure is located in the installation hole 23. The partition plate 22 is provided with a partition hole, and the locking block 12 is clamped into the clamping hole 10 through the partition hole. The pipe can be formed by stretching through a mold and then bent to form the upper pipe 1. The above structure is easy to process and has low cost.

[0038] As shown in the figure, the specific connection structure between the surrounding cloth and the surrounding rod: the card slot 8 is a circular slot and the width of the slot opening of the card slot 8 is smaller than the diameter of the card slot 8, and the surrounding rod is a round rod; a cloth sleeve is provided at the edge of the surrounding cloth, and the surrounding rod is located in the cloth sleeve. The circular structure is easy to process and manufacture. The surrounding rod is first inserted into the cloth sleeve, and then the surrounding rod with the cloth sleeve is inserted into the card slot 8 through the port of the card slot 8 as a whole, and the surrounding cloth extends out through the slot opening of the card slot 8. The above structure is convenient to install, and the connection position between the surrounding cloth and the upper surrounding pipe 1 is misaligned with the sliding position of the sliding connector 3, so there will be no problem of being stuck with the cloth sleeve or pulling each other, resulting in unsmooth sliding.

[0039] As shown in the figure, the unlocking member 7 includes a handle seat 24 fixed to the upper surrounding pipe 1 and a handle plate 25 hinged to the handle seat 24. The handle seat 24 is fixed to the upper surrounding pipe 1 by screws. The steel wire rope 9 is connected to the handle plate 25 through a rope hole provided on the upper surrounding pipe 1, and the other end of the steel wire rope 9 is fixedly connected to the slider 14 through the mounting hole 23. Therefore, by pulling the handle plate 25 to rotate, the steel wire rope 9 can be pulled.
