Description

Technical Field

[0001] This utility model relates to the field of pet carrier technology, and in particular to a pet carrier with adaptive adjustable stiffness. Background Art

[0002] With the development of society, more and more families are keeping pets, and pet carriers are an essential item for pet keeping.

[0003] Most existing pet carriers are foldable and can be stored away. When not in use, the outer cover and frame can be stored or disassembled and the outer cover washed. When needed, the frame can be unfolded and the outer cover put back on. However, with long-term use, the outer cover will stretch or loosen due to the support of the frame mechanism and frequent washing. This makes the outer cover loose and lacking in firmness and tension. When the pet moves around inside, the outer cover is prone to shifting, affecting its effectiveness. Utility Model Content

[0004] To overcome the problems in the prior art, this utility model provides a pet carrier with adaptive adjustable stiffness that can effectively stretch the outer sleeve in real time to ensure that the outer sleeve remains taut.

[0005] This utility model provides the following technical solution: a pet carrier with adaptive adjustable stiffness, including an outer cover and a support mechanism disposed inside the outer cover for supporting the outer cover;

[0006] The support mechanism includes two side supports, each of which is a frame structure with four sides formed by four crossbars, and each of the side supports includes a first top bar, a first bottom bar and two side bars;

[0007] Two second base rods are respectively connected between two first base rods to cooperate with the two first base rods to form a frame structure with four sides;

[0008] Two second push rods are respectively connected between two first push rods, and can cooperate with the two first push rods to form a frame structure with four sides;

[0009] Each second push rod includes a first rod portion, a second rod portion, and an elastic structure disposed between the two. One end of each first rod portion is fixed to a first push rod, and one end of each second rod portion is free to move. When one end of the second rod portion abuts against the first push rod, the elastic structure is compressed, and the reaction force of the elastic structure pushes the first push rod away, thereby realizing the real-time expansion of the outer sleeve.

[0010] The elastic structure is a spring, and its two ends are fixedly connected to the first rod and the second rod, respectively.

[0011] As a further improvement, the elastic structure includes a spring and two positioning pins; the first rod and the second rod are hollow tubes with inner and outer sleeves, and positioning holes are provided radially through the sides of the first rod and the second rod. The spring is concentrically arranged inside the second top rod, and the two positioning pins pass through the positioning holes and the spring respectively to fix the spring in the second top rod.

[0012] As a further improvement, the spring is a tension spring, and the locating pin passes through the locating hole and the hooks at both ends of the tension spring.

[0013] As a further improvement, when the second push rod is in its natural state, the spring is in a semi-compressed state within the second push rod.

[0014] As a further improvement, one end of the second push rod is rotatably hinged to the first push rod, and the other end can be folded together with the first push rod to achieve folding or perpendicular to the first push rod to achieve support when rotating.

[0015] As a further improvement, the hinge connection points of the two second push rods are respectively located at one end of the two first push rods, and the two hinge connection points are located on different sides of the two first push rods.

[0016] As a further improvement, the second push rod is provided with a first fixing block and a second fixing block at both ends. The first fixing block has a limiting hole for the first push rod to pass through, and the first fixing block has an opening for one end of the second push rod to extend into and be hinged by a pin. The second fixing block can be positioned and connected to the first push rod by a positioning part, Velcro, or buckle.

[0017] As a further improvement, the second fixing block is provided with two arc-shaped positioning parts, which are used to achieve positioning connection with the arc-shaped rod surface of the first top rod when folding and supporting.

[0018] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0019] This utility model, by setting an elastic structure on the support mechanism, can effectively provide outward support to the outer sleeve in real time by using the reaction force after compression when the outer sleeve is opened. As the outer sleeve becomes loose after long-term use, the elastic structure can also adaptively adjust to support it outward to a certain stiffness. The overall structural design is simple and ingenious, easy to implement and low in manufacturing cost. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods. Unless otherwise specified, the materials and reagents used in the following embodiments can be obtained commercially.

[0026] Please refer to Figures 1 to 4 An adaptive stiffness pet carrier includes an outer cover 1 and a support mechanism 2 disposed inside the outer cover 1 for supporting the outer cover 1;

[0027] Two side supports 21, each of the side supports 21 is a frame structure with four sides formed by four crossbars, which can be rectangular or irregular frame (some sides are multi-segment broken lines to facilitate the installation of the outer sleeve 1). Each of the side supports 21 includes a first top rod 211, a first bottom rod 212 and two side rods 213.

[0028] Two second base rods 22 are respectively connected between two first base rods 212 to form a frame structure with four sides. The frame can be rectangular or irregular (some sides are multi-segment broken lines to facilitate the installation of the outer sleeve 1).

[0029] Two second top rods 23 are respectively connected between two first top rods 211, and can cooperate with the two first top rods 211 to form a frame structure with four sides. In this embodiment, it is a rectangular frame.

[0030] Each second push rod 23 includes a first rod portion 231, a second rod portion 232, and an elastic structure 233 disposed between the two. One end of each first rod portion 231 is fixed to a first push rod 211, and one end of each second rod portion 232 is free to move. When one end of the second rod portion 232 abuts against the first push rod 211, the elastic structure 233 is compressed, and the reaction force of the elastic structure 233 pushes the first push rod 211 away, thereby realizing the real-time opening of the top of the outer casing 1, especially for opening and closing the opening and disassembly during use.

[0031] By setting an elastic structure 233 on the support mechanism 2, the elastic structure 233 can effectively provide support to the outer sleeve 1 in real time by using the reaction force after compression when the outer sleeve 1 is opened. As the outer sleeve 1 becomes loose after long-term use, the elastic structure 233 can also achieve adaptive adjustment to support it outward to a certain stiffness. The overall structural design is simple and ingenious, easy to implement and low in manufacturing cost.

[0032] Please refer to Figure 3 and Figure 4 The elastic structure 233 includes a spring 2331 and two positioning pins 2332; the first rod portion 231 and the second rod portion 232 are hollow tubes and are disposed inside and outside each other. Positioning holes are provided radially through the sides of the first rod portion 231 and the second rod portion 232. The spring 2331 is concentrically disposed in the second top rod 23. The two positioning pins pass through the positioning holes and the spring 2331 respectively, and are used to fix the spring 2331 in the second top rod 23.

[0033] The elastic structure 233 uses a positioning pin that passes through the positioning hole on the second push rod 23 to pass through the main body of the spring 2331 set inside the second push rod 23. The positioning pin compresses and fixes the spring 2331 in the second push rod 23. During installation, first, one end of the spring 2331 is roughly positioned at a positioning hole. Then, a positioning pin is passed through to achieve pre-positioning. Then, the two rods are interlocked. The long rod is inserted into the hollow tube to compress the other end of the spring 2331. At the same time, it is ensured that the other positioning hole is visible. Then, another positioning pin is inserted. This fixing method can easily pre-compress and fix the spring 2331. The operation is convenient. If the following tension spring 2331 is used, the positioning pin can be directly passed through the two hooks during installation.

[0034] Please refer to Figure 3 and Figure 4The spring 2331 is a tension spring, and the locating pins pass through the locating hole and the hooks at both ends of the tension spring. Its tension spring structure can fully and effectively adapt to the installation space of the elastic structure 233 in the second push rod 23, while ensuring its stability during use and avoiding damage to the main body of the spring 2331 caused by the locating pins during the extension and retraction of the spring 2331.

[0035] Furthermore, when the second push rod 23 is in its natural state, the spring 2331 is in a semi-compressed state within the second push rod 23. This structural design effectively ensures sufficient outward thrust and prevents the spring 2331 from being completely relaxed in its natural state. In this case, insufficient compression would result in insufficient reaction force when it contacts the first push rod 211, thus failing to effectively expand the outer sleeve 1.

[0036] Please refer to Figure 2 and Figure 3 One end of the second top rod 23 is rotatably hinged to the first top rod 211, and the other end can be folded together with the first top rod 211 when rotating, or supported perpendicularly to the first top rod 211.

[0037] With this connection structure, the switching between the folding and supporting states of the second top rod 23 can be achieved effectively and quickly, and the elastic structure 233 can be used to expand the outer sleeve 1 in the supporting state.

[0038] Please refer to Figure 2 and Figure 3 The hinge connection points of the two second top rods 23 are respectively located at one end of the two first top rods 211, and the two hinge connection points are located on different sides of the two first top rods 211, so that when folded, the two second top rods 23 can be respectively rested on the two first top rods 211, so as to achieve a reasonable structure when folded, and also avoid the problem of excessive volume and space occupation when the two second top rods 23 are simultaneously rested on one first top rod 211.

[0039] Please refer to Figure 3 The second top rod 23 has a first fixing block 3 and a second fixing block 4 at both ends. The first fixing block 3 has a limiting hole for the first top rod 211 to pass through, and an opening for one end of the second top rod 23 to extend into, where it is hinged by a pin. The second fixing block 4 can be positioned and connected to the first top rod 211 by a positioning part, Velcro, or buckle. The structure of the first fixing block 3 effectively and conveniently fixes the second top rod 23 to the first top rod 211, and can be replaced separately when damaged in subsequent use. The second fixing block 4 can quickly fix the first top rod 211 and the second top rod 23 to each other when folded, making it easy to store.

[0040] Furthermore, the second fixing block 4 is provided with two arc-shaped positioning parts, which are used to achieve positioning connection with the arc surface of the first top rod 211 when folding and supporting. The structure of the arc positioning parts can achieve low-cost and stable cooperation and fixation between the second top rod 23 and the first top rod 211 when folding. The structure design is simple and the function is easy to implement.

[0041] In addition, the elastic structure 233 can also be directly replaced by a spring 2331, i.e., an ordinary helical spring 2331. The two ends of the elastic structure 233 are fixedly connected to the first rod 231 and the second rod 232 respectively. It can be quickly connected by welding, bonding or binding. The elastic coefficient and thickness of the spring 2331 can be flexibly selected according to the size of the outer sleeve 1, so that when the support mechanism 2 is opened, the outer sleeve 1 can be opened outward without breaking. Similarly, the other elastic structures 233 mentioned above can also be done in this way.

[0042] The overall folding structure of the pet carrier support mechanism 2 is existing technology and will not be described in detail here. Please refer to the folding support mechanism 2 of a pet house with announcement number CN211983174U or the folding support structure of a pet carrier that is easy to transport with announcement number CN220292758U.

[0043] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
