Technical Field

[0001] The utility model relates to the technical field of pet ladders, in particular to pet ladders. Background Art

[0002] With the improvement of people's living standards, people will keep some pets for companionship, and the pet peripherals will be driven accordingly. In order to facilitate pets to climb and play, pet ladders are needed. However, the traditional pet ladders have a fixed structure, which occupies a large space and is only suitable for use at home, inconvenient to carry, use and store, reducing the applicability of the ladders. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is: to solve the problem that the traditional pet ladder has a fixed structure, which occupies a large space, is only suitable for use at home, inconvenient to carry, use and store, and reduces the applicability of the ladder. Now, a pet ladder is provided.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a pet ladder includes a plurality of ladder boards, and a plurality of the ladder boards are hinged to each other by connecting rods to form a telescopic four-bar mechanism. A limiting mechanism for limiting the extending length of the pet ladder is arranged on the telescopic four-bar mechanism;

[0005] The limiting mechanism includes a first limiting rod and a second limiting rod. One end of the first limiting rod is hinged to one of the adjacent two connecting rods, and one end of the second limiting rod is hinged to the other of the adjacent two connecting rods. The other end of the first limiting rod is hinged to the other end of the second limiting rod. A rotation stopping mechanism is arranged on the first limiting rod and the second limiting rod. The rotation stopping mechanism is used to prevent the first limiting rod and the second limiting rod from continuing to rotate in the extending direction of the pet ladder when the first limiting rod and the second limiting rod are straightened. Compared with the prior art, in this solution, by arranging a rotation stopping mechanism on the first limiting rod and the second limiting rod of the limiting mechanism, when the ladder extends to the limit position, the first limiting rod and the second limiting rod are straightened. At this time, the first limiting rod and the second limiting rod are stopped from rotating by the rotation stopping mechanism and will not continue to rotate in the rotating direction, ensuring the stable and reliable use of the ladder when it is extended, avoiding the problem that the ladder collapses and cannot be used due to continuous rotation, making the telescopic ladder use stable and reliable, and at the same time being convenient to carry and store, improving the applicability of the ladder.

[0006] In order to implement the anti-rotation mechanism, in some preferred embodiments, the anti-rotation mechanism includes an anti-rotation groove provided at the other end of the first limiting rod, and an anti-rotation block is provided at the other end of the second limiting rod. When the first limiting rod and the second limiting rod are straightened, the anti-rotation block is clamped in the anti-rotation groove. Through the cooperation of the anti-rotation groove on the first limiting rod and the anti-rotation block on the second limiting rod, the anti-rotation when the first limiting rod and the second limiting rod are straightened is realized, and its structure is simple.

[0007] In order to facilitate the cooperation between the anti-rotation block and the anti-rotation groove, in some preferred embodiments, the anti-rotation block has a guiding section and a stopping section connected to each other. The guiding section is an inclined surface that is gradually inclined towards the second limiting rod, and the stopping section protrudes from the side surface of the first limiting rod close to the second limiting rod. By providing the guiding section and the stopping section on the anti-rotation block, on the one hand, it is convenient for the anti-rotation groove to cooperate with the anti-rotation block, preventing the ladder from being stable and reliable at the extreme position of extension, and on the other hand, when extending or retracting, the guiding section of the anti-rotation block on the first limiting rod contacts the second limiting rod and provides a certain frictional force, ensuring that the ladder will not extend or retract easily when extending or retracting.

[0008] In some preferred embodiments, the joint point at one end of the first connecting rod coincides with the hinge point of one of the two adjacent connecting rods and the ladder board.

[0009] In some preferred embodiments, the joint point at one end of the second connecting rod coincides with the hinge point of the other of the two adjacent connecting rods and the ladder board.

[0010] In order to facilitate the carrying of the ladder, in some preferred embodiments, a carrying handle is provided on one of the several ladder boards. By providing a carrying handle on the ladder, it is convenient to carry the ladder after contraction.

[0011] In order to facilitate the carrying of the ladder, in some preferred embodiments, a backpack strap is provided on several of the ladder boards. The backpack strap is convenient for people to carry on their backs, providing an additional carrying method and facilitating the carrying of the ladder after contraction.

[0012] In order to facilitate the correction of the posture of the ladder, in some preferred embodiments, a handle is provided on the upper ladder board among several ladder boards. By providing a handle on the upper ladder board, the handle can straighten the extended ladder, realizing the change of the ladder's posture, so that the ladder is in a better posture and position.

[0013] Since one end of the ladder is leaning against the wall, the upper sides of the ladder near the wall collide with each other, and in severe cases, the tie rods are damaged, reducing the service life of the ladder. Preferably, in some embodiments, anti-collision strips are provided on the connecting rods where several of the ladder boards are located outside the upper ladder board. By providing anti-collision strips on the tie rods on one side of the upper end board ladder, the anti-collision strips reduce the impact intensity on the tie rods, ensuring the stable and reliable use of the ladder and extending the service life of the ladder.

[0014] Preferably, in some embodiments, a bottom plate or a support frame is hinged below several of the ladder boards at the lower end ladder board.

[0015] The beneficial effects of the present invention are as follows: When the pet ladder of the present invention is in use, by providing an anti-rotation mechanism on the first limiting rod and the second limiting rod of the limiting mechanism, when the ladder extends to the extreme position, the first limiting rod and the second limiting rod are straightened. At this time, the first limiting rod and the second limiting rod are stopped from rotating by the anti-rotation mechanism and will not continue to rotate in the rotation direction, ensuring the stable and reliable use of the ladder when it is extended, avoiding the problem that the ladder collapses and cannot be used due to continuous rotation, making the telescopic ladder stable and reliable in use, and at the same time being convenient to carry and store, improving the applicability of the ladder, and avoiding the problem that the traditional pet ladder has a fixed structure, which occupies a large space and is only suitable for use at home, is not convenient to carry, use and store, and reduces the applicability of the ladder.

[0033] Embodiment 1

[0034] As Figures 1-10 shown, a pet ladder includes four ladder boards 1. In this embodiment, there are four ladder boards 1. Of course, the number of ladder boards 1 can be three, five, six or more in addition to four. The four ladder boards 1 are hinged to each other by connecting rods 2 to form a retractable four-bar linkage mechanism. The adjacent two ladder boards 1 are spaced apart and arranged in a staggered manner. The four ladder boards 1 are arranged in the same direction. A limiting mechanism is provided on the retractable four-bar linkage mechanism. The limiting mechanism is used to limit the extended length of the pet ladder and also plays a safety protection role to prevent the ladder from extending too long and causing dangerous problems.

[0035] The limiting mechanism includes a first limiting rod 3 and a second limiting rod 4. One end of the first limiting rod 3 is hinged to one of the adjacent two connecting rods 2, and one end of the second limiting rod 4 is hinged to the other of the adjacent two connecting rods 2. The other end of the first limiting rod 3 is hinged to the other end of the second limiting rod 4. A rotation stopping mechanism is provided on the first limiting rod 3 and the second limiting rod 4. The stopping mechanism includes a rotation stopping groove 5 provided at the other end of the first limiting rod 3, and a rotation stopping block 6 is provided at the other end of the second limiting rod 4. When the first limiting rod 3 and the second limiting rod 4 are straightened, the rotation stopping block 6 is clamped in the rotation stopping groove 5. When the first limiting rod 3 and the second limiting rod 4 are straightened, the rotation stopping mechanism prevents the first limiting rod 3 and the second limiting rod 4 from continuing to rotate in the first direction. In this embodiment, the first direction is the direction in which the second limiting rod rotates towards the first limiting rod when the ladder extends.

[0036] Since the ladder generally does not need to extend to the extreme position, the rotation stopping block 6 has a guiding section 601 and a stopping section 602 connected to each other. The guiding section 601 is an inclined surface that gradually inclines towards the direction of the second limiting rod 4, and the stopping section 602 protrudes from the side surface of the first limiting rod 3 close to the second limiting rod 4. When the second limiting rod 4 contacts the guiding section 601 on the first limiting rod 3, the guiding section 601 will exert a force on the second limiting rod 4 to prevent it from continuing to rotate, and the greater the contraction resistance is. Therefore, when contracting, the stability and reliability of the ladder contraction can be ensured, and at the same time, there can also be a force when extending to ensure that the ladder maintains a certain extended length.

[0037] The joint point at one end of the first connecting rod 2 coincides with the hinge point between one of the two adjacent connecting rods 2 and the ladder board 1, and the joint point at one end of the second connecting rod 2 coincides with the hinge point between the other of the two adjacent connecting rods 2 and the ladder board 1.

[0038] One of the four ladder boards 1 is provided with a carrying strap 7, and the four ladder boards 1 are provided with a backpack strap 8.

[0039] A handle 9 is provided on the upper ladder board 1 among the four ladder boards 1. In this embodiment, the handle 9 is made of plastic and anti-slip protrusions are provided on the handle 9. Of course, in addition to plastic, the handle 9 can also be made of sponge.

[0040] An anti-collision strip 10 is provided on the connecting rod 2 outside the upper ladder board 1 among the four ladder boards 1.

[0041] A bottom plate 11 is hinged below the lower ladder board 1 among the four ladder boards 1.

[0042] Embodiment 3

[0043] The difference between Embodiment 3 and Embodiment 1 or 2 is that as Figure 11 shown, a support frame 12 is hinged below the lower ladder board 1 among several ladder boards 1.

[0044] When the above-mentioned pet ladder is in the initial state, the ladder is in a contracted state. At this time, the ladder boards 1 are stacked on top of each other. The ladder can be lifted by the carrying strap 7, or carried on the back by the backpack strap 8, and carried to the required position, such as in a car, or outdoors, etc.

[0045] When in use, by pulling the ladder board 1, the telescopic four-link 2 mechanism is extended. At the same time, the first limiting rod 3 and the second limiting rod 4 of the limiting mechanism are rotated relative to each other and rotated in the straightening direction, and the anti-rotation groove 5 gradually rotates towards the anti-rotation block 6. When the ladder is extended to the required limited length, at this time, the second limiting rod 4 contacts the guiding section 601 of the anti-rotation block 6, which can prevent the ladder from continuing to extend and ensure the stable and reliable use of the ladder. The second limiting rod 4 gradually disengages under the action of the guiding section 601 of the anti-rotation block 6 until the anti-rotation block 6 is clamped in the anti-rotation groove 5. When the ladder is extended to the limit length, the posture of the ladder is adjusted through the handle 9, and the anti-collision strip 10 prevents the connecting rod 2 from hitting the wall.

[0046] Based on the ideal embodiments of the present invention as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
