Description

Technical Field

[0001] This application relates to the field of pet supplies technology, and in particular to an adjustable-size pet cage. Background Technology

[0002] A pet cage is a container specifically designed to restrict a pet's movement. They are typically made of metal, plastic, or wood. Common types of pet cages include airline crates, car cages, D1 enclosures, and glass cages. Among these, metal cages, such as wire mesh cages, are common. These are relatively sturdy, well-ventilated, and suitable for larger, more active pets, such as large dogs. Plastic cages are also common; they are usually lightweight, easy to move, and some even have good insulation, making them more suitable for smaller pets. In the prior art, the relevant technology can be referred to in Chinese Patent Application No. CN202110451174.X, which discloses a pet cage. When unfolded, the frames support each other, making it difficult to bend and with high strength. When folded, it is easy to operate and has a clever folding principle. When folded, the bottom frame, top frame, first side frame, second side frame and third side frame are flat and folded together, resulting in a compact structure. The pet cage occupies little space and is easy to carry and store.

[0003] In the process of developing this application, the inventors discovered the following problems with the prior art: First, the main advantage of the above-mentioned device is that it can be folded, making it easy to carry and store. However, the placement space of the above-mentioned device is fixed and does not have the effect of adjustable internal space. Since pets are constantly growing, the above-mentioned device cannot adapt to the growth of pets. Second, although there are foldable pet cages in the existing solutions, the folding and fixing methods are generally limited by buckle locking or button locking to limit the folding part. As a result, there are situations where the structure is unstable or the adjustment is not flexible enough. In particular, when subjected to the impact of a large dog inside the cage, the instability of the folding connection structure and the lack of flexibility in adjustment are particularly significant. Summary of the Invention

[0004] The purpose of this application is to provide an adjustable-size pet cage.

[0005] The adjustable-size pet cage provided in this application adopts the following technical solution: An adjustable-size pet cage includes a pet cage body and a high-strength elastic rope. The pet cage body is composed of a mesh frame assembly and a size adjustment mechanism. The upper surface of the pet cage body is provided with a high-strength elastic rope, and there are two sets of high-strength elastic ropes, which are arranged in an X-shape. The size adjustment mechanism includes an "L"-shaped plate and a telescopic adjustment mechanism. Four sets of "L"-shaped plates are provided, with telescopic adjustment mechanisms on opposite sides of each set. Each telescopic adjustment mechanism includes a cylinder and a sliding rod. The sliding rod is located within the inner cavity of the cylinder, passing through the side end face of the cylinder, with one end extending to one side of the cylinder. A connecting block is provided at one end of the sliding rod, and a baffle is provided on the outer diameter surface of the sliding rod. A stop block is provided on the side wall of the inner cavity of the cylinder. A through hole is drilled through the outer diameter surface of the cylinder, and the through hole is connected to a silicone plug. High-strength elastic mesh is connected to the bends of the four sets of "L"-shaped plates.

[0006] By adopting the above technical solution, the pet cage body is unfolded in three-dimensional space, thereby achieving the effect of adjustable internal space of the pet cage body. As the pet grows, the space of the pet cage body can be adjusted in a timely manner to adapt to the pet's growth. Furthermore, by using gas fixation, the position of the sliding rod is limited through through holes and silicone plugs, which facilitates the size adjustment of the pet cage body during use and makes it easy to limit the adjustment position later.

[0007] A sealing ring is provided on one side of the cylinder mounting block and the contact surface with the slide rod. The baffle is fixedly installed on the outer diameter surface of the slide rod, and an annular sealing sheet is provided on the contact surface between the baffle and the inner cavity of the cylinder. Two sets of through holes and silicone plugs are provided, and the two sets of through holes and two sets of silicone plugs are arranged symmetrically.

[0008] By adopting the above technical solution, the pet cage body is sized through an "L"-shaped plate, a telescopic adjustment mechanism, a cylinder, a sliding rod, a connecting block, a baffle, a stop block, a through hole, and a silicone plug in the size adjustment mechanism. Four sets of "L"-shaped plates are provided on one side, and these four sets are adjusted vertically, horizontally, and vertically through the telescopic adjustment mechanism. The position of the sliding rod is limited by the stop block, through hole, and silicone plug, thus facilitating the fixed shape of the pet cage body after adjustment. When limiting the position of the cylinder, sliding rod, connecting block, baffle, and stop block in the telescopic adjustment mechanism through the through hole and silicone plug, only some of the through holes and silicone plugs need to be engaged and blocked; it is not necessary to engage and block all of them. This arrangement facilitates the vertical, horizontal, and forward / backward extension and retraction of the pet cage body.

[0009] The baffle separates the inner cavity of the cylinder, and the two sides of the baffle are the left cavity and the right cavity, respectively. The baffle and the inner cavity of the cylinder form a sliding structure, and the slide rod and the cylinder form a sliding structure.

[0010] By adopting the above technical solution, the inner cavity of the cylinder is separated by a baffle, and the two sides of the baffle are the left cavity and the right cavity, respectively. When the through hole and silicone plug are used for blocking, the sliding rod and the baffle can be prevented from moving left and right, thereby realizing the extension and retraction of the pet cage body in the up and down, left and right and front and back, which facilitates the limiting and fixing of the shape of the pet cage body after adjustment.

[0011] The pet cage body has six sets of size adjustment mechanisms, which are symmetrically arranged. The mesh frame assembly has eight sets, and the eight sets of mesh frame assembly and the six sets of size adjustment mechanisms form a cube shape.

[0012] By adopting the above technical solution, the six sets of size adjustment mechanisms and eight sets of mesh frame components can be easily assembled into a cube, which is beneficial for placing pets inside the pet cage body.

[0013] The eight sets of mesh frame components are installed at the corners of the six sets of size adjustment mechanisms, and the contact surfaces of the eight sets of mesh frame components and the six sets of size adjustment mechanisms are welded together.

[0014] By adopting the above technical solution, the welding connection facilitates the fixed connection of the mesh frame components and the size adjustment mechanism, thereby ensuring the stability of the device and ensuring the stability and safety of the device when placing medium and large dogs.

[0015] The telescopic adjustment mechanism is provided in several sets. The four sets of "L"-shaped plates have the same length at both ends and are evenly and symmetrically arranged. The two sets of "L"-shaped plates at the top and the two sets of "L"-shaped plates at the bottom form an up-down sliding structure through the telescopic adjustment mechanism. The two sets of "L"-shaped plates on one side form a left-right sliding structure with the two sets of "L"-shaped plates on the other side through the telescopic adjustment mechanism.

[0016] By adopting the above technical solution, the size adjustment mechanism is provided in six sets, which are respectively formed by the mesh frame assembly and the size adjustment mechanism to form a cube shape on the six sides. Furthermore, the four sets of "L"-shaped plates form an up-down and left-right sliding structure, thereby enabling all six sides of the cube shape to have up-down and left-right sliding structures, thus realizing the size adjustment of the length, width, and height of the pet cage body.

[0017] The telescopic adjustment mechanism is specifically a telescopic structure, and the telescopic ends of several groups of the telescopic adjustment mechanism are arranged in an alternating manner, with a flexible telescopic protective cover provided around the outer periphery of the several groups of the telescopic adjustment mechanism.

[0018] By adopting the above technical solution, the telescopic ends of the telescopic adjustment mechanism are arranged in an alternating manner, and a flexible telescopic protective cover is provided around the telescopic adjustment mechanism, which facilitates the adjustment of the length, width, and height of the pet cage body, and also helps to protect the telescopic adjustment mechanism.

[0019] The mesh frame assembly consists of a frame body, connecting holes, and a metal mesh. The inner side of the frame body is provided with connecting holes, and the metal mesh is connected to the frame body through the connecting holes.

[0020] By adopting the above technical solution, the mesh frame component consists of a frame body, connecting holes and metal mesh, which ensures the sturdiness of the pet cage body while also facilitating ventilation and observation of the interior of the pet cage body.

[0021] A temperature and humidity sensor is provided on the side of the "L"-shaped plate away from the high-strength elastic rope, and a universal wheel pre-interface is provided on the bottom end face of the "L"-shaped plate in the size adjustment mechanism.

[0022] By adopting the above technical solution, a temperature and humidity sensor is installed to detect the temperature and humidity inside the pet cage body, and the universal wheel pre-interface on the bottom end of the "L"-shaped plate facilitates the movement of the pet cage body.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. First, the size of the pet cage body is adjusted through the size adjustment mechanism. The pet cage body is unfolded in three-dimensional space, thereby achieving the effect of adjustable internal space. As the pet grows, the space of the pet cage body can be adjusted in time to adapt to the pet's growth. Furthermore, the position of the sliding rod is limited by gas fixing, through through holes and silicone plugs. During use, it is convenient to adjust the size of the pet cage body and to limit the adjustment position in the future. 2. The pet cage body is sized via an "L"-shaped plate, a telescopic adjustment mechanism, a cylinder, a sliding rod, a connecting block, a baffle, a stop, a through hole, and a silicone plug. There are four sets of single-sided "L"-shaped plates, which are adjusted vertically and horizontally via the telescopic adjustment mechanism. The stop, through hole, and silicone plug limit the position of the sliding rod, facilitating the fixation of the pet cage body's adjusted shape. The through hole and silicone plug also limit the position of the sliding rod within the telescopic adjustment mechanism. When limiting the positions of the cylinder, sliding rod, connecting block, baffle, and stop, it is only necessary to fasten and block some through holes and silicone plugs. It is not necessary to fasten and block all through holes and silicone plugs. The above arrangement facilitates the extension and retraction of the pet cage body in the up, down, left, right, and front and back. The baffle divides the inner cavity of the cylinder, and the two sides of the baffle are the left cavity and the right cavity, respectively. When the through holes and silicone plugs are blocked, the sliding rod and baffle can be prevented from moving left and right, which makes it easy to limit and fix the shape of the pet cage body after adjustment. 3. The six sets of size adjustment mechanisms and eight sets of mesh frame components facilitate the assembly of a cube, which is beneficial for placing pets inside the pet cage body. The welding connection facilitates the fixed connection between the mesh frame components and the size adjustment mechanisms, ensuring the stability of the device and the stability and safety when placing medium and large dogs. There are six sets of size adjustment mechanisms, which are respectively arranged on the six sides of the cube shape formed by the mesh frame components and the size adjustment mechanisms. The four sets of "L" shaped plates form an up-down and left-right sliding structure, so that all six sides of the cube shape have up-down and left-right sliding structures, realizing the adjustment of the length, width and height of the pet cage body. 4. The telescopic adjustment mechanism has staggered telescopic ends, and a flexible telescopic cover is provided around the telescopic adjustment mechanism to facilitate the adjustment of the length, width, and height of the pet cage body, and also to protect the telescopic adjustment mechanism. The mesh frame assembly consists of a frame body, connecting holes, and metal mesh, which ensures the sturdiness of the pet cage body while also facilitating ventilation and observation of the interior of the pet cage body. Temperature and humidity sensors are installed to monitor the temperature and humidity inside the pet cage body, and the universal wheel pre-interface on the bottom surface of the "L"-shaped plate facilitates the movement of the pet cage body.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0026] Example: An adjustable-size pet cage includes a pet cage body 1 and high-strength elastic ropes 2. The pet cage body 1 is composed of a mesh frame assembly 11 and a size adjustment mechanism 12. High-strength elastic ropes 2 are provided on the upper surface of the pet cage body 1, and two sets of high-strength elastic ropes 2 are provided, arranged in an X-shape. The size adjustment mechanism 12 includes an "L"-shaped plate 121 and a telescopic adjustment mechanism 122. Four sets of "L"-shaped plates 121 are provided, and telescopic adjustment mechanisms 122 are provided on the opposite sides of the four sets of "L"-shaped plates 121. The telescopic adjustment mechanism 122 includes a cylinder 1221 and a sliding rod 1222. The sliding rod 1222 is disposed within the inner cavity of the cylinder 1221, penetrates the side end face of the cylinder 1221, and one end of the sliding rod 1222 extends to one side of the cylinder 1221. The cage has a connecting block 1223, and a baffle 1224 is provided on the outer diameter surface of the slide rod 1222. A baffle 1225 is provided on the side wall of the inner cavity of the cylinder 1221. A through hole 1226 is drilled through the outer diameter surface of the cylinder 1221, and a silicone plug 1227 is connected to the through hole 1226. A high-strength elastic net 123 is connected to the bend of the four sets of "L" shaped plates 121. The pet cage body 1 is unfolded in three-dimensional space to achieve the effect of adjustable internal space of the pet cage body 1. As the pet grows, the space of the pet cage body 1 can be adjusted in time to adapt to the growth of the pet. The position of the slide rod 1222 is limited by the through hole 1226 and the silicone plug 1227 through the gas fixation method. During use, it is convenient to adjust the size of the pet cage body 1 and to limit the adjustment position in the future. A sealing ring is provided on the contact surface between the cylinder 1221 and the slide rod 1222 on one side of the mounting block 1225. A baffle 1224 is fixedly installed on the outer diameter surface of the slide rod 1222, and an annular sealing sheet is provided on the contact surface between the baffle 1224 and the inner cavity of the cylinder 1221. Two sets of through holes 1226 and silicone plugs 1227 are provided, and the two sets of through holes 1226 and silicone plugs 1227 are symmetrically arranged. The pet cage body 1 is sized by the "L"-shaped plate 121, telescopic adjustment mechanism 122, cylinder 1221, slide rod 1222, connecting block 1223, baffle 1224, block 1225, through holes 1226, and silicone plugs 1227 in the size adjustment mechanism 12. Four sets of "L"-shaped plates 121 are provided on one side. The “L”-shaped plate 121 is adjusted up, down, left, and right through the telescopic adjustment mechanism 122. The position of the slide rod 1222 is limited by the stop block 1225, through hole 1226, and silicone plug 1227, which helps to limit and fix the shape of the pet cage body 1 after adjustment. When the positions of the cylinder 1221, slide rod 1222, connecting block 1223, baffle 1224, and stop block 1225 in the telescopic adjustment mechanism 122 are limited by the through hole 1226 and silicone plug 1227, it is only necessary to fasten and block some of the through holes 1226 and silicone plug 1227. It is not necessary to fasten and block all the through holes 1226 and silicone plug 1227, which facilitates the telescopic movement of the pet cage body 1 up, down, left, right, and front and back. Baffle 1224 separates the inner cavity of cylinder 1221, with the left and right cavities on either side of baffle 1224. Baffle 1224 and the inner cavity of cylinder 1221 form a sliding structure, as does slide rod 1222 with cylinder 1221. When the inner cavity of cylinder 1221 is separated by baffle 1224, with the left and right cavities on either side, the slide rod 1222 and baffle 1224 are prevented from moving left and right when blocked by through hole 1226 and silicone plug 1227. This allows for the vertical, horizontal, and forward / backward extension and retraction of the pet cage body 1, facilitating the limitation and fixation of the adjusted shape of the pet cage body 1. The size adjustment mechanism within the pet cage body 1... The cage body 1 has six sets of size adjustment mechanisms 12, which are symmetrically arranged. The cage frame 11 has eight sets of mesh frame components 11, which together with the six size adjustment mechanisms 12 form a cube shape. The six size adjustment mechanisms 12 and the eight mesh frame components 11 are easy to form into a cube, which is beneficial for placing pets inside the cage body 1. The eight mesh frame components 11 are installed at the corners of the six size adjustment mechanisms 12. The contact surfaces of the eight mesh frame components 11 and the six size adjustment mechanisms 12 are welded together. The welding connection facilitates the fixed connection between the mesh frame components 11 and the size adjustment mechanisms 12, ensuring the stability of the device and the stability and safety of the device when placing medium and large dogs. The telescopic adjustment mechanism 122 is provided with several sets. The four sets of "L"-shaped plates 121 have the same length at both ends and are evenly and symmetrically arranged. The two sets of "L"-shaped plates 121 at the top and the two sets of "L"-shaped plates 121 at the bottom form a vertical sliding structure through the telescopic adjustment mechanism 122. The two sets of "L"-shaped plates 121 on one side form a horizontal sliding structure through the telescopic adjustment mechanism 122 and the two sets of "L"-shaped plates 121 on the other side. The size adjustment mechanism 12 is provided with six sets, which form a cube shape on the six sides of the mesh frame assembly 11 and the size adjustment mechanism 12. The four sets of "L"-shaped plates 121 form a vertical and horizontal sliding structure, so that all six sides of the cube shape have vertical and horizontal sliding structures, realizing the size adjustment of the length, width and height of the pet cage body 1. The telescopic adjustment mechanism 122 is specifically a telescopic structure, with the telescopic ends of several sets of telescopic adjustment mechanisms 122 arranged in an alternating manner. A flexible telescopic protective cover is provided around the outer periphery of each set of telescopic adjustment mechanisms 122. The staggered arrangement of the telescopic ends and the flexible telescopic protective cover facilitate adjustment of the length, width, and height of the pet cage body 1, while also protecting the telescopic adjustment mechanism 122. The mesh frame assembly 11 consists of a frame body 111, connecting holes 112, and a metal mesh 113. Connecting holes 112 are provided on the inner side of the frame body 111, and the metal mesh 113 is connected to the frame body 111 through the connecting holes 112. The mesh frame assembly 11, composed of the frame body 111, connecting holes 112, and metal mesh 113, ensures the safety of the pet cage. While ensuring the robustness of the main body 1, it also facilitates ventilation and observation of the interior of the pet cage 1. A temperature and humidity sensor 3 is installed on the side of the "L"-shaped plate 121 away from the high-strength elastic rope 2. The bottom surface of the "L"-shaped plate 121 in the size adjustment mechanism 12 is provided with a universal wheel pre-interface, in which the temperature and humidity sensor 3 is installed to monitor the temperature and humidity inside the pet cage 1. The universal wheel pre-interface on the bottom surface of the "L"-shaped plate 121 facilitates the movement of the pet cage 1. In this embodiment, the temperature and humidity sensor 3, the universal wheel pre-interface, and the universal wheels are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, and we will not go into detail here.

[0027] The implementation principle of this application embodiment is as follows: First, the pet cage body 1 is sized by means of the "L"-shaped plate 121, telescopic adjustment mechanism 122, cylinder 1221, slide rod 1222, connecting block 1223, baffle 1224, stop block 1225, through hole 1226, and silicone plug 1227 in the size adjustment mechanism 12. Four sets of "L"-shaped plates 121 are provided on one side, and the four sets of "L"-shaped plates 121 are adjusted up, down, left, and right by the telescopic adjustment mechanism 122. The slide rod 1223 is adjusted by the stop block 1225, through hole 1226, and silicone plug 1227. The position of the rod 1222 is limited to facilitate the fixed position of the pet cage body 1 after adjustment. When the positions of the cylinder 1221, slide rod 1222, connecting block 1223, baffle 1224 and stop block 1225 in the telescopic adjustment mechanism 122 are limited by the through hole 1226 and silicone plug 1227, it is only necessary to fasten and block some of the through holes 1226 and silicone plug 1227, without having to fasten and block all of the through holes 1226 and silicone plug 1227, which facilitates the extension and retraction of the pet cage body 1 in the up, down, left, right and back directions. Specifically, baffle 1224 divides the inner cavity of cylinder 1221, with the left and right cavities on either side of baffle 1224. When blocked by through hole 1226 and silicone plug 1227, the sliding rod 1222 and baffle 1224 are prevented from moving left and right, allowing the pet cage body 1 to extend and retract vertically, horizontally, and backward. This facilitates the limiting and fixing of the adjusted shape of the pet cage body 1. Furthermore, the welded connection facilitates the fixed connection between the mesh frame assembly 11 and the size adjustment mechanism 12, ensuring the stability of the device. The size adjustment mechanism 12 has six sets, forming a cube shape on the six sides of the mesh frame assembly 11 and the size adjustment mechanism 12. Four sets of "L"-shaped plates 121 form a vertical and horizontal sliding structure, allowing the cube to slide vertically and horizontally. The pet cage body 1 has six sliding structures on all six sides, allowing for adjustment of its length, width, and height. The telescopic adjustment mechanism 122 has its telescopic ends arranged in an alternating pattern, and a flexible telescopic cover is provided around the telescopic adjustment mechanism 122 to facilitate adjustment of the pet cage body 1's length, width, and height, and to protect the telescopic adjustment mechanism 122. The mesh frame assembly 11 consists of a frame body 111, connecting holes 112, and a metal mesh 113, ensuring the sturdiness of the pet cage body 1 while also facilitating ventilation and observation of the interior of the pet cage body 1. A temperature and humidity sensor 3 is installed to detect the temperature and humidity inside the pet cage body 1, and the universal wheel pre-interface on the bottom surface of the "L"-shaped plate 121 facilitates the movement of the pet cage body 1.
