Description

Technical Field

[0001] The present invention belongs to the technical field of carts for companion pets, and specifically relates to a folding basket device for carts for companion pets.

Background Art

[0002] A pet cart is a new tool for traveling with pets. Pet carts have various uses. With a cart, especially when no one is at home, it is possible to take an elderly dog outside to breathe fresh air so that it does not spend its days gloomily at home. Furthermore, people who keep pets know that pet breeding is prohibited in public places such as supermarkets, shopping malls, and even indoors at some scenic spots. Although the entry of pets other than guide dogs is prohibited by regulations, it is possible to put them in a travel bag or cart. In such cases, a pet cart is useful. In fact, there are many shopping malls in China that provide pet carts.

[0003] When going to crowded places, because dogs are small, they are likely to be stepped on or kicked when walking on the ground. If a dog is timid or sensitive, it can be prevented from coming into direct contact with other pets or eating things on the roadside. The important parts of existing pet carts are the cart body and the basket for placing the pet, but all existing baskets have a fixed structure, so they cannot be used for folding carts and will affect people's movement and carrying.

[0004] Therefore, how to provide a folding basket device for carts for companion pets is an issue that those skilled in the art need to quickly solve.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In view of the above, the present invention provides a foldable basket device for a companion pet cart that is easy to use in a folded state and easy to carry during travel.

Means for Solving the Problems

[0006] To achieve the above object, the present invention adopts the following technical solutions. The foldable basket device for a companion pet cart includes a mounting bottom plate used as the base of the foldable basket, a bottom pipe rack fixed to the mounting bottom plate and having two parallel guide steps. An extendable locking assembly is provided on the outer wall of each of the guide steps, and a control mechanism for controlling the telescopic movement of the locking assembly is hinged to one end. a lifting pipe rack arranged in parallel with the bottom pipe rack, located above the bottom pipe rack, and provided with two parallel sliding steps. Two sets of deformation support mechanisms for controlling the up-and-down movement of the lifting pipe rack are connected between the lifting pipe rack and the bottom pipe rack. The deformation support mechanism has a fixed end and a sliding end. The fixed end is fixedly connected to the edge of one end of the bottom pipe rack and the lifting pipe rack, and the sliding end is slidably connected to the guide step and the sliding step. The locking assembly is used to limit the position of the sliding end in the guide step. A cloth member is connected between the lifting pipe rack and the bottom pipe rack, and the deformation support mechanism is located inside the cloth member. The lifting pipe rack a handle removably connected to the central part of the lifting pipe rack, with multiple sets of roof support poles positioned and hinged at positions close to the side ends, and a soft awning cloth connected to the roof support poles.

[0007] The technical effects of the present invention are as follows. A combination of a bottom pipe rack, a lifting pipe rack, and a deformation support mechanism forms a frame for deforming and folding the basket. The control mechanism controls the state of entering and exiting the guide stage of the locking assembly, and further controls the deformation of the deformation support mechanism. As can be understood, when the locking assembly is controlled by the control mechanism to return inside the guide stage, the deformation support mechanism becomes foldable, which is advantageous for carrying. On the other hand, when the basket is used, the deformation support mechanism unfolds, and the locking assembly is used to unfold and fix the deformation support mechanism, thereby ensuring the normal use state of the basket. Further, the handle is used to hold the basket, and the roof support pole can be folded or deformed to unfold or fold the tarpaulin, which is useful for storing and using pets in public places.

[0008] Preferably, the bottom pipe rack and the lifting pipe rack are both of a square structure, and the control mechanism is located at the central part of one end of the bottom pipe rack.

[0009] The resulting technical effects are as follows. When the user operates the control mechanism at one end, the locking assembly can be controlled to release the lock on the form of the deformation support mechanism.

[0010] Preferably, the control mechanism includes a fixed seat, a buckle plate, a guide post, and a pull cord. The fixed seat is fixed to the central part of one end of the bottom pipe rack. The buckle plate is hinged to the fixed seat and is located outside the bottom pipe rack. The guide post is fixed to the fixed seat and is located inside the bottom pipe rack. A relief groove through which the pull cord and the guide post penetrate is provided on the side wall of the bottom pipe rack. One end of the pull cord is connected to the buckle plate, and the other end is guided by the guide post and connected to the locking assembly.

[0011] The technical effects generated thereby are as follows. Since the buckle plate receives the pulling force by the pulling string, it is in close contact with the fixed seat in the stationary state, and the pulling force by the pulling string is from the locking assembly. The guide post is used to change the direction of the pulling string, and the wear of the pulling string due to the friction with the bottom pipe rack can also be avoided.

[0012] Preferably, the locking assembly includes a mounting seat, a sliding body, and a locking pin. The mounting seat is a long pipe receiving portion. The mounting seat is fixed inside the guide step. The sliding body is slidably connected inside the mounting seat in the axial direction of the mounting seat. One end of the sliding body is connected to the other end of the pulling string. An inclined guide surface is provided on the sliding body. The locking pin is slidably connected up and down inside the mounting seat and is located above the sliding body. A spring for moving the locking pin downward is attached between the locking pin and the mounting seat. The locking pin is provided with a contact surface that fits with the inclined guide surface. The locking pin is used to limit the sliding end in the deformation support mechanism. A long groove for the locking pin to extend is provided on the bottom wall of any of the mounting seat, the sliding body, and the guide step. The pulling string pulls and moves the sliding body in the axial direction so that the locking pin moves upward against the spring force, thereby hiding the locking pin inside the guide step.

[0013] The technical effects generated thereby are as follows. The pipe racks of the mounting seat and the guide step establish a fixed connection relationship. The sliding body is slidably connected to the mounting seat in the axial direction. The purpose is to change the up-and-down movement of the locking pin through the axial movement. There is a fitting inclined surface between the sliding body and the locking pin. The sliding body is connected to the pulling string. Due to the action of the locking pin, the sliding body can always hold the pulling force on the pulling string. The up-and-down movement of the locking pin is expressed as controlling the folding state of the basket by a part of the locking pin extending outside the guide step to limit the deformation of the deformation support mechanism.

[0014] Preferably, the deformation support mechanism has an "X" - shaped structure. Both ends on one side of the deformation support mechanism are fixed ends, and both ends on the other side are sliding ends. A sliding sleeve is provided at the sliding ends. The sliding sleeve is slidably connected to a guiding stage and a sliding stage. A long - shaped slot for fitting with a locking pin is provided on the bottom side of the sliding sleeve.

[0015] The technical effects resulting therefrom are as follows. The X - shaped deformation support mechanism is advantageous for supporting deformation. When one end is fixed and the other end slides, the compression degree of the deformation support mechanism can be adjusted.

[0016] Preferably, insertion seats are fixed to all central parts of the side ends of the lifting pipe rack. The insertion seat corresponding to the central part of the long side of the quadrilateral is used for removably connecting a handle. The insertion seat corresponding to the central part of the short side of the quadrilateral is used for engaging a roof support pole. There is a locking button for connecting the insertion seat on the roof support pole.

[0017] The technical effects resulting therefrom are as follows. The handle is removably connected to the lifting pipe rack. Of course, the roof support pole can be deformably adjusted and positioned on the lifting pipe rack, which is advantageous for maintaining the stable state of the folded roof support pole.

[0018] Preferably, insertion heads are connected to both side ends of the handle. The roof support pole and the handle are coaxially positioned and hinge - connected to the insertion head.

[0019] The technical effects resulting therefrom are as follows. The handle is connected to the lifting pipe rack by the insertion head, and the connection relationship with a plurality of roof support poles is also established.

[0020] Preferably, a pressing portion is provided at the outer bottom end of the insertion head, the insertion seat has a positioning slot, the insertion head is inserted into the corresponding insertion seat, and the pressing portion is engaged in the positioning slot. A pedestal is provided at the outer top of the insertion head, a button is provided at one end of the pedestal, a plurality of protruding engaging portions are provided on the peripheral side of the button, and an engaging groove for fitting with the engaging portion is provided inside the side end of the handle. When the button is pressed, the engaging portion disengages from the engaging groove, the handle can rotate around the insertion head, and when the button returns, the engaging portion contacts and is limited by the engaging groove, and the handle is fixed to the insertion head and cannot rotate.

[0021] The resulting technical effect is as follows. By pressing the button, the angle between the handle and the lifting pipe rack can be adjusted.

[0022] Preferably, the side ends of the plurality of roof support poles are coaxially and rotatably connected inside the pedestal. The pedestal is provided with a concave portion or a convex portion on the side close to the roof support pole, and the side end of the roof support pole is provided with a concave portion or a convex portion. The rotation of the roof support pole is limited between the pedestal and the adjacent roof support pole and between two adjacent roof support poles through the fitting of the concave portion and the convex portion on the approaching side.

[0023] The resulting technical effect is as follows. The angle adjustment positions can be fixed between adjacent roof support poles and between the roof support pole and the adjacent insertion head on the adjacent side, which is advantageous for folding or unfolding the roof tarpaulin.

[0024] Preferably, an engaging groove seat for connecting a folding cart is provided at the edge of one end of the bottom side of the placement bottom plate, and a movable lock is provided at the edge of the other end. The placement bottom plate is connected to the pipe rack of the folding cart by the engaging groove seat and the movable lock.

Modes for Carrying Out the Invention

[0027] The following clearly and completely describes the technical solution in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present invention.

[0028] Referring to FIGS. 1-10 of the present invention, a folding basket device for a companion pet cart according to an embodiment of the present invention includes a placement bottom plate 1 used as the base of the folding basket, a bottom pipe rack 2 fixed to the placement bottom plate 1 and having two parallel guide sections 21. An extendable locking assembly 3 is provided inside each of the guide sections 21 on the outer wall of the guide section. Specifically, when implementing, only the part that engages and restricts the deformation support mechanism of the locking assembly extends. A control mechanism 4 for controlling the telescopic movement of the locking assembly 3 is hinged at one end to the bottom pipe rack 2, a lifting pipe rack 5 arranged in parallel with the bottom pipe rack 2, located above the bottom pipe rack 2, and having two parallel sliding sections 51. Two sets of deformation support mechanisms 6 for controlling the up and down movement 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 edge of one end of the bottom pipe rack 2 and the lifting pipe rack 5. The sliding end 62 is slidably connected to the guide section 21 and the sliding section 51. The locking assembly 3 is used to limit the position of the sliding end 62 in the guide section 21. Specifically, when implementing, the control mechanism simultaneously controls and moves the locking assemblies in the two guide sections. A cloth member is connected between the lifting pipe rack 5 and the bottom pipe rack 2. The deformation support mechanism 6 is located inside the cloth member. The lifting pipe rack 5, Removably connected to the central part of the lifting pipe rack 5, a plurality of sets of roof support poles 8 are positioned and hinge-connected at positions close to the side ends, a soft awning cloth is connected to the roof support poles 8, and as can be understood, a handle 7 is included which enables the awning to be set up or withdrawn by means of the roof support poles and the soft awning cloth.

[0029] In some other embodiments, the bottom pipe rack 2 and the lifting pipe rack 5 are both of square structures, the control mechanism 4 is located at the central part of one end of the bottom pipe rack 2, and similarly, the handle and the roof support poles are arc-shaped to match the shape of the partial contour of the square.

[0030] In some other embodiments, the control mechanism 4 includes a fixed seat 41, a buckle plate 42, a guide post 43, and a pulling string. The fixed seat 41 is fixed to the central part of one end of the bottom pipe rack 2. The buckle plate 42 is hinge-connected to the fixed seat 41 and is located outside the bottom pipe rack 2. The guide post 43 is fixed to the fixed seat 41 and is located inside the bottom pipe rack 2. An escape groove through which the pulling string and the guide post 43 penetrate is provided on the side wall of the bottom pipe rack 2. One end of the pulling string is connected to the buckle plate 42, and the other end is guided by the guide post 43 and connected to the locking assembly 3.

[0031] When specifically implemented, since the control mechanism controls two locking assemblies simultaneously, there are two guide posts for guiding the pulling strings on the corresponding sides respectively. In order to reduce the deformation angle of the pulling strings and reduce the lifting force of the buckle plate, the two pulling strings are arranged alternately after passing through the guide posts and are fixed to the pulling string posts on the buckle plate.

[0032] In some other embodiments, the locking assembly 3 includes a mounting seat 31, a sliding member 32, and a locking pin 33. The mounting seat 31 is an elongated pipe receiving portion, and the mounting seat 31 is fixed inside the guiding step 21. The sliding member 32 is slidably connected inside the mounting seat 31 in the axial direction of the corresponding mounting seat 31. One end of the sliding member 32 is connected to the other end of the pulling string. An inclined guiding surface 321 is provided on the sliding member 32. The locking pin 33 is slidably connected up and down inside the mounting seat 31 and is located above the sliding member 32. A spring for moving the locking pin 33 downward is attached between the locking pin 33 and the mounting seat 31. An abutting surface that fits with the inclined guiding surface 321 is provided on the locking pin 33. The locking pin 33 is used to limit the sliding end in the deformation support mechanism 6. An elongated groove in which the locking pin 33 extends is provided on the bottom wall of any of the mounting seat 31, the sliding member 32, and the guiding step 21. The pulling string pulls and moves the sliding member 32 in the axial direction so that the locking pin 33 moves upward against the spring force, thereby hiding the locking pin inside the guiding step. Since the sliding member is located inside the mounting seat and at this time the pulling string penetrates the trace in the mounting seat and is connected to the sliding member, in addition to the guiding function, the trace in the mounting seat can avoid the wear of the bottom pipe rack caused by the pulling string.

[0033] In some other embodiments, the deformation support mechanism 6 has an "X" - shaped structure. Both ends of one side of the deformation support mechanism 6 are fixed ends 61, and both ends of the other side are sliding ends 62. A sliding sleeve 621 is provided on the sliding end 62. The sliding sleeve 621 is slidably connected to the guiding step 21 and the sliding step 51. An elongated slot that fits with the locking pin 33 is provided on the bottom side of the sliding sleeve 621. That is, as a result, the locking pin establishes a relationship of engaging with the elongated slot in the sliding sleeve.

[0034] In some other specific embodiments, the insertion seats 9 are fixed to all the central portions of the side ends of the lifting pipe rack 5. The insertion seats corresponding to the central portions of the long sides of the quadrilateral are used for the handle 7 to be removably connected.

A button 14 is provided at one side end of the pedestal 13. A plurality of protruding engaging portions 15 are provided on the circumferential side of the button 14. An engaging groove 16 for fitting with the engaging portion is provided inside the side end of the handle 7. When the button 14 is pressed, the engaging portion 15 disengages from the engaging groove 16. In addition, the button cannot rotate and can only be pressed, which is a limitation based on the fitting of the engaging portion and the engaging groove in the pedestal. The handle 7 can rotate around the insertion head. When the button 14 returns, the engaging portion 15 contacts and is limited by the engaging groove 16, and the handle 7 is fixed to the insertion head and cannot rotate. According to this structure, the folding angle of the handle can be adjusted.

[0037] In some other embodiments, the lateral ends of the plurality of roof support poles 8 are coaxially and rotatably connected to the inside of the pedestal 13. The pedestal 13 is provided with a concave or convex portion on the side close to the roof support pole, and the lateral ends of the roof support poles 8 are provided with concave or convex portions. The rotation of the roof support poles is limited through the fitting of the concave and convex portions on the approaching sides between the pedestal 13 and the adjacent roof support pole and between two adjacent roof support poles.

[0038] In some other embodiments, an engaging groove seat 17 for connecting the folding cart 19 is provided at the edge of one end of the bottom side of the mounting bottom plate 1, and a movable lock 18 is provided at the edge of the other end. The mounting bottom plate 1 is connected to the pipe rack of the folding cart 19 by the engaging groove seat 17 and the movable lock 18.

[0039] Specifically, it is used as follows.

[0040] Attach the roof support pole, the soft awning cloth and the handle to the corresponding insertion seats, and control the lifting state of the lifting pipe base by the control mechanism to deploy or fold the basket. Note that the folding function of the basket does not affect the folding function of the roof, and these two do not interfere with each other.

[0041] When the engaging groove seat (front hook) at the bottom of the basket is hung on the base of the body of the folding cart, the movable lock (automatic lock) at the rear is operated to be attached to the rear frame of the body. After fixing the body and the basket, check the locked state.
