Description

Technical Field

[0001] The utility model relates to a pet box, in particular to a handle installation structure of the pet box. The handle is fixed on the top of the pet box to facilitate the movement of the pet box. Background Art

[0002] A pet box is a common device used to store, transport and display pets. It is usually composed of an upper box and a lower box. In daily life and commercial scenarios, the portability and stability of a pet box are crucial to the safety and comfort of the user and the pet. In order to facilitate users to carry and move the pet box, a handle is usually provided on the top.

[0003] There are two main types of handles commonly found on the market: one is a rotatable handle, which lies flat on the top of the box when not in use, and can be lifted up by the user when in use; the other is a fixed handle, which is always in an upright position and is fixedly connected to the upper box by screws or bolts.

[0004] However, there are some problems with the installation of fixed handles. In the actual installation process, due to improper screw fixation or inconsistent force during tightening, the screws are often screwed off-center or screwed loose. This situation not only affects the installation quality and stability of the handle, but also may increase the time and cost of assembly, and there are safety hazards. When the screws are not fixed firmly, the handle may loosen or even fall off, causing unsafe use of the pet box and even posing a threat to the safety of the pet and the user. Utility Model Content

[0064] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0065] In the description of the present utility model, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the attached drawings, or the directions or positional relationships in which the utility model product is usually placed when in use, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. "First", "second", etc. are only for the purpose of making the description easier to understand, without any other directional meaning, and cannot be used as a limitation on the present utility model.

[0066] like Figure 1 The figure is a schematic diagram of the overall structure of the pet box in the utility model. In the prior art, the assembly between the handle and the upper box body usually requires the use of screw components, which has a complex assembly process, low production efficiency, high operating requirements for operators, and high production costs. Based on this existing technical problem, the utility model aims to improve the assembly structure of the handle and the top of the upper box body, and the specific technical solution is as follows:

[0067] like Figures 2 to 6 As shown, a handle mounting structure 100 of a pet box is shown. The layout and functional design of each component of the handle mounting structure 100 of the pet box are carefully considered to ensure that the user obtains the best stability and safety during use. In particular, it includes a concave cavity 101 at the top of the upper box body, a handle 10 and an anti-drop limit block 20. The setting of the concave cavity 101 is very practical. The two ends of the concave cavity 101 are provided with a first concave assembly groove 30 and a second concave assembly groove 40. The two ends of the concave cavity 101 are provided with a first concave assembly groove 30 and a second concave assembly groove 40.

[0068] The shapes and positions of these grooves are precisely calculated to ensure that the handle can be accurately inserted and firmly fixed on the pet box. The inclined distribution of the first assembly groove 30 allows the first end 12 to be plugged in and assembled first, providing sufficient space for the vertical insertion of the second end 13, thereby simplifying the assembly process (this technical means will be described in detail below).

[0069] In addition, if Figures 9 to 11 As shown, the handle 10 includes an arc-shaped body 11, a first end 12 and a second end 13; the first end 12 is connected to the first assembly groove 30, and the second end 13 is connected to the second assembly groove 40. The arc-shaped body 11 of the handle takes into consideration aesthetics and ergonomics.

[0070] Furthermore, a connecting arm 14 is provided on the lower end surface of the second end portion 13, and the cooperation with the anti-dropping limiting block 20 further enhances the stability of the handle, effectively preventing the handle from accidentally falling off, thereby increasing the stability and safety of the pet box.

[0071] The first end portion 12 includes an outer end surface, on which a first hook portion t1 extending away from the second end portion 13 is provided; a first notch h1 and a first baffle v1 are provided at the bottom of the first assembly groove 30, and the first hook portion t1 passes through the first notch h1 and is hooked on the first baffle v1.

[0072] It should be noted that the first end portion 12 is inserted into the first assembly groove 30 in the first direction and forms a limit relationship in the lateral direction. Specifically, the first hook portion t1 extends outward and upward at the first end portion 12. When the first hook portion t1 hooks the first baffle v1, the two form a mutual limit in the lateral direction.

[0073] The above technical means enable the first end 12 to be accurately positioned during the insertion into the first assembly groove 30, and when the first hook t1 hooks the first baffle v1, a lateral mutual limit is formed between the two. Such a limit relationship ensures the stable installation of the first end 12, and effectively ensures the stability and assembly efficiency when the second end 13 is assembled laterally.

[0074] On the other hand, Figures 11 to 14 As shown, the second end portion 13 is inserted into the second assembly groove 40 in the second direction and forms a limiting relationship in the longitudinal direction. After the second end portion 13 and the second assembly groove 40 are assembled, a locking member is longitudinally fixed between the two to prevent the second end portion 13 of the handle from accidentally falling out of the second assembly groove 40. Preferably, the locking member is an anti-falling limiting block 20.

[0075] Specifically, the lower end surface of the second end portion 13 is provided with two connecting arms 14 extending downward, and the outer side of the connecting arms 14 is provided with a second hook portion t2. The bottom of the second assembly groove 40 is provided with a second baffle v2, and the second baffle v2 is provided with a second notch h2. The connecting arm 14 of the second end portion 13 passes through the second notch h2, and the second hook portion t2 is hooked on the second baffle v2.

[0076] like Fig.12 As shown, the two connecting arms 14 are parallel and spaced apart, and the hooks of the second hooks t2 are arranged in opposite directions. A clamping rib is preferably arranged at the position where the second baffle v2 is to be hooked by the hook member; after the two second hooks t2 pass through the second notch h2, they are relatively hooked on the corresponding clamping ribs to facilitate the hooking stability of the second hooks t2.

[0077] The above technical means effectively ensures the limiting relationship between the second end portion 13 and the second assembly groove 40 in the longitudinal direction, thereby ensuring the stable installation of the handle.

[0078] In addition, it should be noted that, firstly, since the first end 12 and the second end 13 form lateral and vertical limits respectively when plugged into the slot, the assembly structure of the first end 12 will naturally obtain a locking effect after the second end 13 is plugged and clamped, so there is no need to set an additional locking piece at the first end. Since the second end 13 is clamped vertically, there is a possibility of accidental disengagement due to vertical pulling. Therefore, fixing the anti-disengagement limit block 20 at the second end 13 can enhance the stability of the entire handle 10. The existence of the anti-disengagement limit block 20 can ensure that the handle 10 will not accidentally disengage or loosen when the second end 13 is subjected to an external pulling force.

[0079] It should be noted that the anti-dropping limit block 20 Figure 6 , Figures 15 to 19 As shown, a cavity f is formed between the two connecting arms 14, and the anti-slip limiting block 20 is at least partially inserted into the cavity f. The limiting block 20 presses the two connecting arms 14 to prevent the second hook portion t2 of the second end portion 13 of the handle from detaching from the second baffle v2.

[0080] The anti-dropping limiting block 20 includes a bottom 21, a top pressure plate 22 on the bottom 21, and third hooks t3 on two vertical arms; the second end 13 includes a front end face and a rear end face, and the front end face and the rear end face are respectively provided with a third notch h3.

[0081] The connecting arm 14 is located in a first pair of directions of the second end portion 13 , and the third notch h3 is located in a second pair of directions of the second end portion 13 .

[0082] The bottom wall of the handle 10 where the second end 13 is located is open, the anti-slip limiting block 20 passes through the second assembly groove 40 and the open bottom wall of the handle from bottom to top, and the top pressure plate 22 is pressed between the two connecting arms 14, and the third hook t3 is hooked on the third notch h3 of the second end 13.

[0083] The pressing plate 22 of the anti-dropping limiting block 20 effectively presses the two connecting arms 14, so that the second end 13 of the handle is additionally supported to prevent it from accidentally falling off the second baffle v2. This pressing action enhances the stability of the handle, making it difficult for the handle to loosen or fall off during use.

[0084] In addition, the arrangement of the pressing plate 22 on the bottom 21 and the third hook portion t3 effectively prevents the second end portion 13 of the handle from accidentally falling off.

[0085] It is also necessary to explain that the limiting block can pass through the second assembly groove 40 and the open bottom wall of the handle to achieve a close fit with the second end 13 of the handle, thereby not affecting the normal use of the handle. This technical means not only ensures the stable installation of the handle 10, but also optimizes the compactness of the overall structure.

[0086] In the handle installation structure of the utility model, the handle part also includes a handle cover 15. The upper surface of the handle 10 is a hollow structure, and a reinforcing rib is provided on the hollow structure. The handle cover 15 is connected and fixed to the handle 10 to close the hollow structure. This not only reduces the weight of the handle, but also enhances the stability and durability of its structure. The addition of the handle cover 15 can effectively close the hollow structure of the handle, prevent debris or dust from entering, and keep the handle clean and beautiful. The functionality and aesthetics of the handle are further improved, and the overall quality and user experience of the product are enhanced.

[0087] Further preferably, the two ends of the arc-shaped handle are aligned with the top wall of the upper box body at the outer edge of the cavity 101; this not only makes the handle more stable during installation, but also improves the aesthetics and consistency of the overall appearance. At the same time, the first assembly groove 30 is tilted on the wall of the cavity 101. This tilted design makes it easier to plug and assemble the first end 12 first, and reserves enough space for the second end 13 to be vertically inserted into the second assembly groove 40. In this way, the second end 13 can be inserted into the second assembly groove 40 more smoothly, ensuring the smooth progress of the entire installation process. This optimized design not only improves assembly efficiency, but also further enhances the stability and reliability of the product, providing users with a better user experience.

[0088] In addition, preferably, the bottom plate of the cavity 101 at the top of the upper box body adopts a downwardly concave arc design, while the handle 10 adopts an upwardly protruding arc design. Such a design can form a longitudinal gripping space between the bottom plate of the cavity 101 and the arc-shaped handle 10. This spatial layout not only makes the handle more ergonomic and improves the user's grip comfort, but also provides a larger operating space, allowing the user to operate the pet box more easily. At the same time, the coordination between the arc-shaped bottom plate and the arc-shaped handle also enhances the overall stability between the handle and the box body.

[0089] During actual installation, take out the required upper shell and handle, and insert the first end 12 of the handle into the first assembly groove 30 in the first direction of the concave cavity 101. Since the first assembly groove 30 is inclined on the wall of the concave cavity 101, the first end 12 can be smoothly inserted and form a lateral limit relationship. The outer end surface of the first end 12 is provided with a first hook t1 extending in a direction away from the second end 13. When the first hook t1 hooks the first baffle v1, the first end 12 is firmly connected, and sufficient lateral space is reserved to facilitate the subsequent plugging of the second end 13 with the second assembly groove 40.

[0090] Next, the second end portion 13 of the handle is inserted into the second assembly groove 40 toward the second direction of the concave cavity 101. The lower end surface of the second end portion 13 is provided with two connecting arms 14 extending downward, and the outer side of the connecting arms 14 is provided with a second hook portion t2. The bottom of the second assembly groove 40 is provided with a second baffle v2 and a second notch h2. After the connecting arm 14 passes through the second notch h2, the second hook portion t2 hooks on the second baffle v2, forming a longitudinal limiting relationship. At the same time, the anti-slip limit block 20 is also placed in the cavity f between the connecting arms 14 to press the two connecting arms 14 to prevent the second end portion 13 of the handle from accidentally detaching from the second baffle v2.

[0091] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

This article uses specific examples to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, the utility model can also be improved and modified without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
