Technical Field

[0001] The utility model belongs to the technical field of companion pet carts, and particularly relates to a folding basket device used in conjunction with a companion pet cart. Background Art

[0002] Pet carts are emerging tools for carrying pets when going out. Pet carts have many uses. With a cart, one can take senior dogs out to breathe fresh air instead of keeping them at home feeling gloomy every day, especially when no one is at home in the whole family. In addition, people who keep pets know that pets are prohibited in public places such as supermarkets, shopping malls, and even indoors in some scenic spots. Although it is stipulated that pets are prohibited from entering except guide dogs, it is okay if they are placed in an out - of - the - way bag or a cart, and then the pet cart will come in handy. In fact, many shopping malls in China now also provide pet carts for use.

[0003] When going to places with a large number of people, because dogs are relatively small in size, they are easily stepped on or kicked when walking on the ground. If the dog is timid or sensitive, it can prevent the dog from directly contacting other people and pets, and prevent the dog from eating random things by the roadside. The important parts of existing pet carts are the vehicle body and the basket for holding pets. However, the current baskets are all fixed - type structures and cannot be used in conjunction with folding carts, which affects people's travel and carrying.

[0004] Therefore, how to provide a folding basket device used in conjunction with a companion pet cart is an urgent problem that those skilled in the art need to solve. Content of the Utility Model

[0011] The technical effect of the utility model is that the bottom tube rack and the lifting tube rack cooperate with the deformation support mechanism to form a frame foundation for the deformation and folding of the basket body. The control mechanism is used to control the state of the locking component extending inward and outward from the guide section, thereby controlling the deformation of the deformation support mechanism. It can be understood that when the locking component is controlled by the control mechanism and retracted into the guide section, the deformation support mechanism can be folded, which is convenient for carrying in this state. When the basket body is in use, the deformation support mechanism is expanded, and the locking component is used for the expansion and positioning of the deformation support mechanism, thereby ensuring the normal use state of the basket body. In addition, the carrying handle is used to facilitate carrying the basket body, and the crown support rod is foldable and deformable, which is used for opening and folding the tarpaulin, which is convenient for placing pets in public places.

[0012] Preferably, the bottom pipe rack and the lifting pipe rack are both square ring structures, and the control mechanism is located in the middle of one end of the bottom pipe rack.

The pulling rope pulls the sliding body to axially move and urges the locking pin to move upward against the spring force, so that the locking pin is hidden inside the guiding section.

[0017] The resulting technical effect is that a fixed connection relationship is established between the mounting seat and the pipe rack of the guiding section. The sliding body is axially slidably connected to the mounting seat. The purpose is to axially move to change the up and down movement of the locking pin. There is a matching inclined surface between the sliding body and the locking pin. The sliding body is connected to the pulling rope. Under the action of the locking pin, the sliding body can always maintain the pulling force on the pulling rope. The up and down movement of the locking pin is manifested as part of the locking pin extending out of the guiding section and limiting the deformation of the deformation support mechanism, thereby controlling the folding state of the basket body.

[0018] Preferably, the deformation support mechanism is an "X"-shaped structure. The two ends on one side of the deformation support mechanism are corresponding fixed ends, and the two ends on the other side are corresponding sliding ends. A sliding sleeve is provided on the sliding end. The sliding sleeve is slidably connected to the guiding section and the sliding section. A long strip-shaped slot hole for cooperating with the locking pin is provided on the bottom side of the sliding sleeve.

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0042] Referring to the attached drawings of the present utility model Figures 1 to 10 , a folding basket device for use with a companion pet stroller according to an embodiment of the present utility model includes:

[0043] The load-bearing bottom plate 1 serves as the base of the folding basket.

[0044] The bottom pipe rack 2 is fixed on the load-bearing bottom plate 1. There are two parallel guiding sections 21 on the bottom pipe rack 2. A locking component 3 that can extend out of the outer wall of the guiding section is provided inside each of the guiding sections 21. Specifically, when implemented, only the part of the locking component used for clamping and limiting the deformation support mechanism extends out. One end of the bottom pipe rack 2 is hinged with a control mechanism 4 for controlling the inward and outward telescoping of the locking component 3.

[0045] The lifting pipe rack 5 is arranged parallel to the bottom pipe rack 2 and is located above the bottom pipe rack 2. There are two parallel sliding sections 51 on the lifting pipe rack 5. Two groups of deformation support mechanisms 6 for controlling the up and down lifting of the lifting pipe rack 5 are connected between the lifting pipe rack 5 and the bottom pipe rack 2. The deformation support mechanism 6 has a fixed end 61 and a sliding end 62. The fixed end 61 is fixedly connected to the bottom pipe rack 2 and one end edge of the lifting pipe rack 5. The sliding end 62 is slidably connected to the guiding section 21 and the sliding section 51. The locking component 3 is used to limit the position of the sliding end 62 on the guiding section 21. Specifically, when implemented, the control mechanism controls the activities of the locking components in the two guiding sections simultaneously. A surrounding cloth is connected between the lifting pipe rack 5 and the bottom pipe rack 2. The deformation support mechanism 6 is located inside the surrounding cloth.

[0046] The lifting handle 7 is detachably connected to the middle of the lifting pipe rack 5. Multiple tree crown support rods 8 are positioned and hinged at a position near the edge end of the lifting handle 7. A soft awning cloth is connected to the tree crown support rods 8. It can be understood that the awning is supported and retracted through the tree crown support rods and the soft awning cloth.

[0047] In some other embodiments, both the bottom pipe rack 2 and the lifting pipe rack 5 are square ring-shaped structures. The control mechanism 4 is located in the middle of one end of the bottom pipe rack 2. Similarly, the lifting handle and the tree crown support rods are arcs matching the local contour shape of the square ring.

[0048] In other some embodiments, the control mechanism 4 includes a fixed seat 41, a pulling plate 42, a guiding column 43 and a pulling rope. The fixed seat 41 is fixed in the middle of one end of the bottom pipe rack 2. The pulling plate 42 is hinged on the fixed seat 41 and is located outside the bottom pipe rack 2. The guiding column 43 is fixed on the fixed seat 41 and is located inside the bottom pipe rack 2. An avoidance notch for the pulling rope and the guiding column 43 to pass through is provided on the side wall of the bottom pipe rack 2. One end of the pulling rope is connected to the pulling plate 42, and the other end is connected to the locking component 3 after being guided by the guiding column 43.

[0049] Specifically, when implemented, since the control mechanism controls two locking components simultaneously, there are two guiding columns, which are respectively used for guiding the pulling ropes on the corresponding sides. In order to slow down the deformation angle of the pulling ropes to reduce the lifting force of the pulling plate, the two pulling ropes are arranged in a staggered layout after passing through the guiding columns and are fixed on the pulling rope columns on the pulling plate.

[0050] In some other embodiments, the latching assembly 3 includes a mounting base 31, a sliding body 32 and a latching pin 33. The mounting base 31 is a long strip-shaped pipe seat, which is fixed inside the guiding section 21. The sliding body 32 is axially slidably connected inside the mounting base 31 corresponding to the mounting base 31. One end of the sliding body 32 is connected to the other end of the pulling rope. An inclined guiding surface 321 is provided on the sliding body 32. The latching pin 33 is slidably connected up and down inside the mounting base 31 and is located above the sliding body 32. A spring for urging the latching pin 33 to move downward is provided between the latching pin 33 and the mounting base 31. An abutting surface for cooperating with the inclined guiding surface 321 is provided on the latching pin 33. The latching pin 33 is used to limit the sliding end on the deformation support mechanism 6. Long strip-shaped notches for avoiding the protrusion of the latching pin 33 are provided on the bottom walls of the mounting base 31, the sliding body 32 and the guiding section 21. The pulling rope pulls the sliding body 32 to axially move and urges the latching pin 33 to move upward against the spring force, so that the latching pin is hidden inside the guiding section. Since the sliding member is located inside the mounting base, the pulling rope needs to pass through the rope channel on the mounting base and be connected to the sliding body at this time. Then the rope channel on the mounting base not only has a guiding function but also can prevent the pulling rope from wearing the bottom pipe rack.

[0051] In some other embodiments, the deformation support mechanism 6 is an "X"-shaped structure. The two ends on one side of the deformation support mechanism 6 are respectively fixed ends 61, and the two ends on the other side are respectively sliding ends 62. A sliding sleeve 621 is provided on the sliding end 62. The sliding sleeve 621 is slidably connected to the guiding section 21 and the sliding section 51. A long strip-shaped slot hole for cooperating with the latching pin 33 is provided on the bottom side of the sliding sleeve 621. That is to say, the latching pin finally establishes a latching relationship with the long strip-shaped slot hole on the sliding sleeve.

[0052] In some other specific embodiments, plug-in seats 9 are fixed in the middle of the side ends of the lifting pipe rack 5. The plug-in seat corresponding to the middle of the long side of the square ring is used for detachably connecting the lifting handle 7, and the plug-in seat corresponding to the middle of the short side of the square ring is used for clamping the tree crown support rod 8. A lock button 10 for connecting the plug-in seat 9 is provided on the tree crown support rod 8. Furthermore, the positioning state of the tree crown support rod after folding is realized.

[0053] In some other embodiments, plug connectors 11 are connected to both side ends of the lifting handle 7. The tree crown support rod 8 and the lifting handle 7 are coaxially and pivotally connected to the plug connectors 11.

[0054] Specifically, a pressing button 12 is provided at the outer bottom end of the plug connector 11. There is a positioning slot hole on the socket 9. When the plug connector 11 is inserted into the corresponding socket, the pressing button is snapped into the positioning slot hole at the same time. A base 13 is provided at the top of the plug connector 11. A button 14 is provided at one side end of the base 13. A plurality of outwardly protruding blocks 15 are provided on the periphery of the button 14. A slot 16 for cooperating with the block is provided on the inner side of the edge of the handle 7. When the button 14 is pressed, the block 15 is disengaged from the slot 16. It should be noted that the button cannot be rotated and can only be pressed, which is based on the cooperation and limitation of the block and the slot on the base. The handle 7 can rotate around the plug connector. When the button 14 is reset, the block 15 contacts the slot 16 for limiting, and the handle 7 and the plug connector are relatively positioned and do not rotate. Through this structure, the folding angle of the handle can be adjusted.

[0055] In some other embodiments, the edges of multiple tree crown support rods 8 are coaxially rotatably connected to the inside of the base 13. A groove or bump is provided on one side of the base 13 close to the tree crown support rod. A groove or bump is provided at the edge of the tree crown support rod 8. The rotation positioning of the tree crown support rods is realized through the cooperation of the grooves and bumps on the closer sides between the base 13 and the adjacent tree crown support rods and between two adjacent tree crown support rods.

[0056] In some other embodiments, a slot seat 17 for connecting the folding cart 19 is provided at one end edge of the bottom side of the bearing base plate 1, and a movable buckle 18 is provided at the other end edge. The bearing base plate 1 is connected to the pipe rack on the folding cart 19 through the slot seat 17 and the movable buckle 18.

[0057] Specific use:

[0058] The tree crown support rod, the soft awning and the handle are installed on the corresponding sockets, and the lifting state of the lifting pipe seat is controlled by the control mechanism, so as to complete the opening or folding of the basket. It should be noted that the folding function of the basket does not affect the folding function of the canopy, and the two will not interfere with each other.

[0059] After hanging the slot seat (front hook) at the bottom of the basket on the base of the folding cart body, operate the movable buckle (automatic lock) at the rear and install it on the rear frame of the body. After fixing the vehicle body and the basket, confirm the locked state.
