Description

Technical Field

[0001] This utility model belongs to the field of pet supplies technology and relates to a pet climbing ladder. Background Technology

[0002] With the improvement of people's living standards and the rise of pet culture, more and more families are choosing to keep pets. People not only regard pets as companions, but also as important members of the family, bringing them endless joy and companionship. When pets are indoors, people usually consider laying down a ladder so that they can climb up to higher play areas. At the same time, the ladder itself can also be part of the pet's play.

[0003] For example, Chinese patent literature discloses a folding dog ladder (application number: 201921729132.2), which includes four ladder units arranged from top to bottom and hinged together end to end. The four ladder units include two first ladder units located in the middle and two second ladder units located at both ends. After the four ladder units are flipped outward into place, the front surfaces of the four ladder units are on the same plane.

[0004] The folding dog ladder has the following shortcomings during use: When unfolding the folding dog ladder, both ends of the ladder need to be placed on fixed objects before it can be used, which limits its application scenarios. In addition, when using the ladder, the four ladder units arranged from top to bottom and hinged end to end need to be flipped outwards one by one until the front surfaces of the four ladder units are on the same plane, which is inconvenient to use. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems with existing technologies by proposing a pet climbing ladder. The technical problem this invention aims to solve is the inconvenience of using existing pet climbing ladders.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A pet climbing ladder includes a ladder body in the shape of steps. The ladder body is characterized by having support legs rotatably connected to the ladder body and a support rod disposed between them. The bottom surface of the ladder body has a cylindrical hinge seat. The hinge end of the support rod is spherical and hinged to the hinge seat. The movable end of the support rod, in use, is engaged with the inner side of the support leg, making the support leg vertical. The hinge seat has a notch. The bottom surface of the ladder body also has a locking groove, and the support rod, in its retracted state, can pass through the notch and have its movable end engaged in the locking groove.

[0008] This pet climbing ladder features a support leg rotatably connected to the ladder body, with a support rod positioned between them. When unfolded, the ladder body, support leg, and support rod form a triangular force distribution. Furthermore, the support leg is vertical, preventing rotation under load by holding the support rod in place. This allows the ladder to unfold automatically without needing to be mounted on a fixed object, making it more convenient to use. The support rod structure increases structural stability while simplifying the design and reducing costs. The ball joint between the support rod and the ladder body allows for omnidirectional rotation with a wide range of motion. Additionally, the hinge seat has a notch opposite to the locking groove, allowing the support rod to engage and be positioned within the locking groove after detaching from the support leg. This enables the support leg to be retracted into the ladder body when folded, making the pet climbing ladder both convenient to use and easy to store.

[0009] In the aforementioned pet climbing ladder, the inner side of the support leg has a U-shaped locking plate and an anti-detachment block located at the opening of the locking plate. The movable end of the support rod is spherical and positioned between the locking plate and the anti-detachment block. The bottom surface of the anti-detachment block is arc-shaped, and the curvature of the arc surface gradually increases from the inside to the outside. This allows the support rod to better engage or disengage from the support leg, while ensuring the stability of the engagement.

[0010] In the aforementioned pet climbing ladder, the hinge seat is inclined toward the support leg, and the notches are multiple and arranged circumferentially along the hinge seat. A petal-shaped clamping arm is formed between adjacent notches, and the hinged end of the support rod is positioned between the clamping arms. This allows the support rod to be universally hinged to the bottom surface of the climbing ladder body.

[0011] In the aforementioned pet climbing ladder, the hinge seat and the locking slot are located on the same step of the climbing ladder body, and the size of the notch provided on the hinge seat facing both the locking slot and the locking plate matches the size of the support rod. The hinge seat and the locking slot being located on the same step of the climbing ladder body allows the support rod to fit snugly and retract onto the bottom surface of the climbing ladder body, preventing interference when the support legs rotate towards the climbing ladder body. Furthermore, the size of the notch provided on the hinge seat facing both the locking slot and the locking plate matches the size of the support rod, ensuring that the support rod is properly engaged with both the support legs and the locking slots of the climbing ladder body, thereby improving the load-bearing capacity and stability of this pet climbing ladder.

[0012] In the aforementioned pet climbing ladder, the upper end of the ladder body has two rotating holes, the cross-section of the support leg is inverted U-shape, and each side of the support leg has a cylindrical rotating shaft. The rotating shafts are respectively inserted into the corresponding rotating holes and fixed by connecting sleeves. This design ensures the reliability of the connection between the ladder body and the support leg, and also makes the assembly and disassembly of the ladder body and the support leg more convenient and quick.

[0013] In the aforementioned pet climbing ladder, one end of the connecting sleeve is closed and cylindrical. The edge of the closed end of the connecting sleeve abuts against the edge of the rotating hole. The open end of the connecting sleeve has several elastic claws. The connecting sleeve is inserted into the rotating shaft, and the elastic claws extend out of the rotating shaft and abut against the support foot. During assembly, simply insert the rotating shafts on both sides of the support into the two rotating holes of the climbing ladder body, and then insert the connecting sleeve into the rotating shaft until the edge of the closed end of the connecting sleeve abuts against the edge of the rotating hole. At this point, the elastic claws on the connecting sleeve, after extending out of the rotating shaft, can automatically abut against the support foot. During disassembly, the user only needs to apply slight force to make the elastic claws of the connecting sleeve close inward and disengage from the support foot. At this point, the connecting sleeve can be easily removed. Finally, the user only needs to disengage the rotating shafts on both sides of the support from the two rotating holes of the climbing ladder body.

[0014] In the aforementioned pet climbing ladder, the bottom surface of the ladder body has a limiting block and a limiting plate located above the limiting block and inclined downwards. The upper end of the support leg has a sealing plate with a limiting groove, and the limiting block is embedded in the limiting groove. The limiting plate can further limit the rotation of the support leg after it is rotated and unfolded, so that the ladder body, support leg, and support rod can better form a triangular force distribution, thereby improving the load-bearing capacity and stability of this pet climbing ladder. At the same time, the limiting groove on the support leg, in conjunction with the limiting block on the ladder body, can guide and limit the rotation of the support leg relative to the ladder body, making the rotation and retraction of the support leg more convenient and precise.

[0015] In the aforementioned pet climbing ladder, the steps of the ladder body are provided with anti-slip mats, the support legs have clearance openings for pets to pass through, the inner sides of the support legs have several reinforcing ribs, and the top surface of the limiting plate has several reinforcing ribs. The anti-slip mats increase friction to prevent pets from slipping, the clearance openings on the support legs allow pets to pass through, making the climbing ladder itself a part of the pet's play area, the reinforcing ribs enhance the structural strength of the support legs, and the reinforcing ribs enhance the structural strength of the limiting plate and the ladder body, making the pet climbing ladder more durable.

[0016] Compared with existing technologies, the advantages of this pet climbing ladder are as follows: This pet climbing ladder has a support leg rotatably connected to the ladder body, with a support rod between the two. When the pet climbing ladder is unfolded, the ladder body, support leg, and support rod form a triangular force distribution. In addition, the support leg is in a vertical position, and under force, the support leg can resist the support rod and prevent rotation. This allows the pet climbing ladder to unfold and be used on its own without needing to be used on a fixed object, making it more convenient to use. Furthermore, after the support rod is detached from the support leg, it can be locked in the locking groove, allowing the support leg to be retracted into the ladder body when folded, making this pet climbing ladder convenient to use and easy to store.

The bottom surface of the ladder body 1 also has a locking groove 1a. In the retracted state, the support rod 3 can pass through the notch 1b1 and the movable end is engaged in the locking groove 1a.

[0026] Reference Figure 2 and Figure 5 Specifically, the inner side of the support foot 2 has a U-shaped snap-fit ​​plate 2a and an anti-detachment block 2b located at the opening of the snap-fit ​​plate 2a. The movable end of the support rod 3 is spherical and positioned between the snap-fit ​​plate 2a and the anti-detachment block 2b. The bottom surface of the anti-detachment block 2b is an arc-shaped surface, and the curvature of the arc-shaped surface gradually increases from the inside to the outside.

[0027] Reference Figure 2 and Figure 4 More specifically, the hinge seat 1b is inclined toward the support foot 2, and there are multiple notches 1b1 arranged along the circumference of the hinge seat 1b. A petal-shaped clamping arm 1b2 is formed between two adjacent notches 1b1, and the hinge end of the support rod 3 is positioned between the clamping arms 1b2.

[0028] Reference Figure 2 and Figure 4 Furthermore, the hinge seat 1b and the snap-fit ​​groove 1a are located on the same step of the ladder body 1, and the size of the notch 1b1 provided by the hinge seat 1b facing both the snap-fit ​​groove 1a and the snap-fit ​​plate 2a matches the size of the rod portion of the support rod 3.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 More specifically, the upper end of the ladder body 1 is provided with two rotating holes 1c, the cross-section of the support leg 2 is inverted "U" shape, and the two sides of the support leg 2 are respectively provided with cylindrical rotating shafts 2c. The rotating shafts 2c are respectively inserted into the corresponding rotating holes 1c and fixed by the connecting sleeve 4. One end of the connecting sleeve 4 is closed and cylindrical, and the edge of the closed end of the connecting sleeve 4 abuts against the edge of the rotating hole 1c. The open end of the connecting sleeve 4 has several elastic claws 4a. The connecting sleeve 4 is inserted into the rotating shaft 2c, and the elastic claws 4a extend out of the rotating shaft 2c and abut against the support leg 2.

[0030] Reference Figure 4 and Figure 5 Furthermore, the bottom surface of the ladder body 1 has a limiting block 1d and a limiting plate 1e located above the limiting block 1d and inclined downwards. The upper end of the support leg 2 has a sealing plate 2d, and the sealing plate 2d has a limiting groove 2d1. The limiting block 1d is embedded in the limiting groove 2d1.

[0032] The following explains how to use this pet climbing ladder:

[0033] When this pet climbing ladder is needed, the user simply rotates and unfolds the support leg 2 relative to the ladder body 1. Then, the user inserts the support rod 3, which is hinged to the ladder body 1, into the locking plate 2a and the anti-detachment block 2b on the inner side of the support leg 2 (the user applies slight force to insert the support rod 3 from the side of the anti-detachment block 2b). Due to the delaying effect of the anti-detachment block 2b, the support rod 3 cannot detach on its own. At this time, the support rod 3 is horizontally positioned, and the ladder body 1, support leg 2, and support rod 3 form a triangular force distribution. In addition, the support leg 2 is in a vertical state, so when subjected to force, the support leg 2 can resist the support rod 3 and will not rotate, thereby improving the load-bearing capacity and stability of this pet climbing ladder, making it safer and more reliable to use. Furthermore, this pet climbing ladder can be unfolded and used on its own without needing to be erected on a fixed object, making it more convenient to use. In addition, the limiting plate 1e can further limit the rotation of the support leg 2 after it is rotated and unfolded, so that the ladder body 1, the support leg 2 and the support rod 3 can better form a triangular force distribution. The clearance notch 2e on the support leg 2 allows the pet to pass through, so that this pet ladder itself can also be used as part of the pet's play.

[0034] When this pet climbing ladder is not in use, the user can use a little force to detach the support rod 3 from the side of the anti-detachment block 2b and the support foot 2. Then, the support rod 3 can be snapped into the snap-fit ​​groove 1a. The user can then simply rotate the support foot 2 relative to the climbing ladder body 1 to retract it until the support foot 2 is hidden inside the climbing ladder body 1. This makes the pet climbing ladder convenient to use and easy to store.
