[0003] The pet cage uses detachable connecting components to connect the frames, making it foldable and portable. However, during assembly and disassembly, the structure requires the operation of multiple independent connecting parts (such as U-shaped blocks and locking blocks) one by one, which is still cumbersome. Furthermore, there is a risk that the connecting parts may become loose or be lost after repeated assembly and disassembly.

[0004] Therefore, it is necessary to propose a portable pet cage to solve the above problems. Utility Model Content

[0005] Technical problem to be solved: The purpose of this utility model is to provide a portable pet cage to solve the problem mentioned in the background art. The existing pet cages achieve the separation of the frame through detachable connecting components to achieve the purpose of folding and carrying. However, during the assembly and disassembly process, multiple independent connecting parts (such as U-shaped blocks and locking blocks) need to be operated one by one, which is still cumbersome. Moreover, after repeated disassembly and assembly, there is a risk that the connecting parts may become loose or be lost.

[0006] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: A portable pet cage includes two oppositely arranged connecting frames and a scissor lift, wherein there are four scissor lifts, which are evenly distributed along the periphery of the connecting frames and are arranged parallel to the four sides of the connecting frames respectively; the fixed hinge points at both ends of each scissor lift are fixedly connected to the connecting frame on the adjacent side, and the movable hinge points at both ends of each scissor lift are slidably connected to the connecting frame on the adjacent side; The curtain fabric has zippers around its perimeter and is fixedly installed in one of the connecting frames by the zippers; The connecting plate is fixedly installed inside another connecting frame; Folded cloth is fitted over the outside of the four scissor lifts, and the two ends of the folded cloth are fixedly connected to the connecting frames on the adjacent sides. Handle, used to lift the pet cage; And the drive assembly used to extend and retract the scissor lift.

[0007] Preferably, the two connecting frames are arranged opposite each other in the horizontal direction. Through holes are provided on the upper part of the front and rear sides and the rear side of the upper and lower ends of the connecting frames. Sliding grooves are provided on the lower part of the front and rear sides and the front side of the upper and lower ends of the connecting frames. A first bolt is provided in the through hole and a second bolt is provided in the sliding groove. The fixed hinge point of the scissor lift is fixedly connected to the scissor lift by the first bolt, and the movable hinge point of the scissor lift is slidably connected to the connecting frame by the second bolt.

[0008] Preferably, the connecting plate is provided with a plurality of ventilation grooves spaced apart along its width direction.

[0009] Preferably, the scissor lift includes two X-shaped scissor arms that are hinged to each other. In the two scissor lifts, at the two hinge points of the two adjacent X-shaped scissor arms, one end of the pin at the upper hinge point passes through the folded fabric and is fixedly installed with a baffle. Both ends of the handle are provided with through holes and are respectively sleeved on the pin between the folded fabric and the baffle through the through holes.

[0010] Preferably, the drive assembly includes a screw rotatably mounted on one of the connecting frames, with both ends of the screw rotatably connected to the connecting frame via bearings, one end of the screw penetrating the connecting frame and fixedly mounted with a crank handle, a screw cylinder threaded onto the screw, and two connecting rods symmetrically fixedly mounted on the screw cylinder, the screw and connecting rods being arranged in a cross shape, and the other ends of the two connecting rods being fixedly connected to the second bolts on adjacent sides respectively.

[0011] Beneficial effects: Compared with the prior art, this utility model provides a portable pet cage with a unique structure and convenient use, and has the following significant advantages: 1. Utilizing a drive assembly consisting of a screw, screw barrel, and connecting rod, along with a scissor lift structure, users can smoothly and synchronously control the extension and retraction of the entire cage simply by turning the crank, achieving one-button expansion and folding – extremely convenient operation. When folded, the size is significantly reduced, making it easy to carry and store, solving the problems of cumbersome operation, time-consuming processes, and easy loss of parts associated with traditional fixed pet cages or those requiring manual disassembly of multiple parts for folding.

[0012] 2. Four scissor lifts are evenly distributed along the perimeter of the rectangular connecting frame and connected to specific connection points (fixed hinge points and sliding hinge points) of the connecting frame. Together with the folded cloth wrapped on the outside, they form a three-dimensional frame with uniform force distribution and high stability when unfolded. Compared with cages assembled by multiple independent buckles or connectors, this integrated telescopic structure has stronger overall rigidity and anti-shaking ability, and can effectively withstand the force generated by pet activities, ensuring safe use.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example 1: This example provides a portable pet cage, which is a direct improvement on an existing pet cage. It has a unique structure. Please refer to [link / reference]. Figure 1-3 As shown, the cage includes two connecting frames 1 arranged laterally opposite each other, four scissor lifts 2, a curtain 3, a connecting plate 4, a folding fabric 14, a handle 15, and a drive assembly. The two connecting frames 1 are basically symmetrical in structure, forming the two end frames of the pet cage.

[0017] Both connecting frames 1 are rectangular frame structures. On each connecting frame 1, through holes 6 are provided on the upper part of the front and rear sides and the rear side of the upper and lower ends. Correspondingly, sliding grooves 7 are provided on the lower part of the front and rear sides and the front side of the upper and lower ends. A first bolt 8 is fixedly installed in the through hole 6, and a second bolt 9 is movably installed in the sliding groove 7. The second bolt 9 can slide along the length direction of the sliding groove 7.

[0018] Four scissor arms 2 are evenly distributed along the periphery of the connecting frame 1, namely located on the front, back, top and bottom sides of the pet cage (corresponding to the four sides of the connecting frame 1). The extension direction of each scissor arm 2 is parallel to the side of the connecting frame 1 on the side where it is located. Each scissor arm 2 consists of two X-shaped scissor arms that are hinged to each other in the middle, forming a common scissor linkage mechanism.

[0019] The specific connection relationship is as follows: For each scissor lift 2, the fixed hinge point at one end (e.g., the upper left hinge point of the rear scissor arm) is fixedly connected to a connecting frame 1 by the first bolt 8; the movable hinge point at the same end (e.g., the lower left hinge point of the rear scissor arm) is slidably connected to the same connecting frame 1 by the second bolt 9; correspondingly, the fixed hinge point at the other end of the scissor lift 2 is fixedly connected to the other connecting frame 1 by the first bolt 8 on the other connecting frame 1, and the movable hinge point at the other end is slidably connected by the second bolt 9 on the other connecting frame 1; in this way, the two ends of the four scissor lifts 2 are respectively connected to two connecting frames 1, forming a three-dimensional frame that can extend and retract laterally (i.e., in the opposite direction of the two connecting frames 1).

[0020] A zipper 17 is sewn around the periphery of the curtain 3 and is detachably fixed to the inside of one of the connecting frames 1 through the zipper 17 to form an openable end face of the pet cage; the connecting plate 4 is fixedly installed to the inside of the other connecting frame 1. In this embodiment, multiple long strip-shaped ventilation grooves 5 are spaced apart along the width direction on the connecting plate 4 to ensure air circulation inside the pet cage.

[0021] A flexible folded fabric 14 is fitted over the outside of the four unfolded scissor arms 2, with its two ends fixedly connected to the outer periphery of the two adjacent connecting frames 1 (e.g., by sewing or gluing). When the scissor arms 2 extend or retract, the folded fabric 14 folds or unfolds accordingly, forming a circumferential enclosure for the pet cage. A handle 15 is used to lift the entire pet cage. Specifically, in the two scissor arms 2, the hinge points of the two adjacent X-shaped scissor arms have two hinge points, one above the other. The upper hinge point is selected, and the pin at this point extends outward, passing through the corresponding openings on the folded fabric 14. A baffle 16 is fixedly installed at the end of the pin to prevent the pin from coming out. Each end of the handle 15 has a through hole, which is fitted onto the two extended pins and located between the folded fabric 14 and the baffle 16, thereby installing the handle 15 on the top of the pet cage.

[0022] The drive assembly is used to drive the scissor lift 2 to extend and retract synchronously, thereby causing the entire pet cage to unfold or retract. The assembly includes a screw 10, a screw barrel 12, two connecting rods 13, and a crank 11. The screw 10 is rotatably mounted on the frame of one of the connecting frames 1 via bearings. It is arranged longitudinally, with one end of the screw 10 extending out of the outside of the connecting frame 1, and the crank 11 is fixedly installed at that end. The screw barrel 12 is fitted onto the screw 10 through its internal thread, forming a threaded transmission pair with the screw 10. The two connecting rods 13 are symmetrically fixedly installed on the outer periphery of the screw barrel 12, and the extension direction of the two connecting rods 13 is perpendicular to the axial direction of the screw 10, so that the screw 10 and the two connecting rods 13 are arranged in a cross shape. The end of each connecting rod 13 away from the screw barrel 12 is respectively connected and fixedly connected to two second bolts 9 located on the same side of the pet cage.

[0023] Working principle: When the length of the pet cage needs to be adjusted (i.e., unfolded or folded), the user turns the crank handle 11. The crank handle 11 drives the screw 10 to rotate around its own axis. Since the screw barrel 12 is connected to the second bolt 9, which is slidably connected in the slide groove 7, through the connecting rod 13, its circumferential rotation is constrained. Therefore, when the screw 10 rotates, the screw barrel 12 moves along the axial direction (i.e., laterally) of the screw 10 under the drive of the thread. The movement of the screw barrel 12 drives the connected movable hinge point (through the second bolt 9) to move synchronously along their respective slide grooves 7 through the two connecting rods 13. This movement forces the included angle of all the scissor arms 2 to change, thereby realizing the smooth extension and retraction of the entire three-dimensional frame, causing the two connecting frames 1 to move closer (folded) or further apart (unfolded). The folded state greatly reduces the vertical space occupied by the pet cage, making it easy to carry and store. The unfolded state provides the pet with ample space to move around.

[0024] Once the pet cage is adjusted to the appropriate length, the zipper 17 on the sides of the curtain 3 can be used to open it, and then the pet can be placed in the pet cage. The ventilation slot 5 ensures the pet's comfort inside the cage. When it needs to be moved, the entire pet cage can be lifted simply by holding the handle 15, making it easy to operate.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
