Description

Technical Field

[0001] The utility model belongs to the field of daily necessities, and particularly relates to a foldable skeleton connecting device and a mosquito net. Background Art

[0002] With the improvement of people's living standards and the increasing requirements for the comfort of living environment, mosquito nets are widely used as an effective anti-mosquito facility. Traditional mosquito nets usually consist of a bracket and a mosquito net cloth covering the bracket. However, most traditional mosquito net brackets adopt a fixed structure design. Although they have good stability, they have disadvantages such as large occupied space, inconvenient handling and storage, which bring inconvenience to users. In recent years, in order to meet the needs of consumers for portability and ease of use, various foldable mosquito nets have emerged on the market. These mosquito nets achieve the folding function by improving the bracket structure, thus facilitating storage and carrying. However, in actual applications, the folding mechanisms of some existing foldable mosquito net products are not stable enough, which easily causes the mosquito net to deform or loosen during use, the operation is complex, and it requires many steps to complete the assembly or disassembly. The automatic unfolding mechanism is missing, and users need to manually adjust the positions of various components when opening the mosquito net, resulting in low efficiency and poor experience.

[0003] A Chinese patent with the publication number CN105332977B discloses a connecting piece for a folding bracket, belonging to the field of folding bracket connecting pieces, and is designed to solve problems such as cumbersome disassembly and assembly and poor load-bearing capacity of existing connecting pieces. The connecting piece for the folding bracket of the present invention includes a hinge part and a locking piece; the hinge part is arranged between a first rod body and a second rod body to be connected, and the second rod body can rotate around the hinge part; when the second rod body is in the unfolded state, the locking piece can fix the second rod body relative to the first rod body. The above device cannot achieve the automatic rebound of the connecting piece, and the assembly speed of the bracket equipped with this connecting piece is slow. Therefore, it is urgent for those skilled in the art to solve the above technical problems. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that in the above-mentioned prior art, the automatic rebound of the connecting piece cannot be achieved, and the assembly speed of the bracket equipped with this connecting piece is slow.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A foldable skeleton connecting device includes a sleeve and an elastic connecting piece; the sleeve includes a first sleeve and a second sleeve, the first sleeve is connected to the second sleeve through the elastic connecting piece, a positioning groove is arranged at one end of the first sleeve, a positioning piece is arranged at one end of the second sleeve, and the positioning piece is slidably installed in the positioning groove to realize the connection between the first sleeve and the second sleeve.

[0007] By adopting the above technical solution, the device allows the mosquito net framework to be folded, greatly reducing the space occupied during storage, facilitating the user to carry and store. The design of the positioning groove and the positioning member, as well as the application of the elastic connecting member, make the unfolding and folding processes simple and fast, without the need for complex assembly steps, enhancing the user experience. The first sleeve and the second sleeve are connected by an elastic connecting member and are stably connected through the positioning groove and the positioning member, ensuring that the entire structure remains stable during use and is not prone to loosening or deformation. When the mosquito net needs to be opened, the characteristics of the elastic connecting member can be utilized to achieve the effect of automatic opening of the framework, reducing the need for manual adjustment and improving the convenience of use. The reasonable material selection and structural design can effectively extend the service life of the product. Especially in the selection of the elastic connecting member, if high-quality and highly durable materials are used, the performance under long-term use can be further guaranteed.

[0008] Further, the first connecting head and the second connecting head are respectively arranged at the head and tail ends of the elastic connecting member. A first limiting groove one and a first limiting hole one that fit with the first connecting head are opened at the head end of the first sleeve, and the first connecting head is clamped in the first limiting groove one or the first limiting hole one; a second limiting groove two and a second limiting hole two that fit with the second connecting head are arranged on the second sleeve, and the second connecting head can be clamped in the second limiting groove two or the second limiting hole two.

[0009] By adopting the above technical solution, the first connecting head and the second connecting head are respectively clamped into the limiting grooves or limiting holes of the first sleeve and the second sleeve. Such a design can ensure a more firm connection between the two parts, reducing loosening or separation caused by external forces. Since the connecting head and the limiting groove / hole are specially designed to fit with each other, no additional tools are required to complete the installation quickly and accurately during the assembly process, greatly simplifying the assembly process and improving the efficiency. When cleaning or replacing components is needed, the user can take out the connecting head from the corresponding limiting groove or limiting hole through simple operations, making the entire structure easy to disassemble and reassemble, facilitating daily maintenance. The precise design reduces the wear between components and extends the service life of the product. At the same time, the good fixing method also protects the elastic connecting member itself from excessive stretching or other forms of damage.

[0010] Further, the end of the first sleeve extends outward to form a limiting end, and the positioning groove is arranged on both sides of the bottom of the limiting end; the head end of the second sleeve extends outward to form a connecting end, and the positioning member is arranged on both sides of the bottom of the connecting end.

[0011] By adopting the above technical solutions, the design of the limiting end and the connecting end increases the thickness and area of the sleeve end, thereby improving the rigidity and compressive capacity of the overall structure. The cooperation between the positioning groove and the positioning member ensures that the two parts of the sleeve can be closely and accurately butted, reducing the movement or misalignment caused by external forces. Since the positioning groove and the positioning member are respectively located on both sides of the bottom of the limiting end and the connecting end, this provides a more stable support point for the elastic connecting member, further enhancing the reliability of the connection. The obvious expansion of the limiting end and the connecting end makes the positions of the positioning groove and the positioning member more intuitive and visible, facilitating the user to quickly find the correct installation position. The simple and clear alignment method reduces the possibility of incorrect assembly, and even users who are not familiar with the product can easily complete the assembly. The optimized structure makes the mosquito net skeleton fold more smoothly, and the sliding fit between the positioning groove and the positioning member helps to achieve a smooth and unobstructed folding action. When the mosquito net needs to be unfolded, the elastic connecting member can quickly return to the open state through a pre-set path, improving the user experience. The reinforced end design can better protect the internal elastic connecting member from damage and extend its service life. The structural improvement reduces the friction between components, reduces the risk of wear, and ensures the safety of long-term use.

[0012] Further, the positioning member includes positioning protrusions, and the positioning protrusions are fixed on both sides of the bottom of the connecting end and are clamped in the positioning groove.

[0013] By adopting the above technical solutions, the precise cooperation between the positioning protrusions and the positioning groove can ensure a firm connection between the two parts of the sleeve, reducing the looseness or misalignment caused by external forces. Since the positioning protrusions are directly embedded in the positioning groove, this provides a more stable support point for the elastic connecting member, enhancing the rigidity and integrity of the entire structure. The design of the positioning protrusions and the positioning groove makes the assembly intuitive and easy to operate. Just align the positioning protrusions and insert them into the corresponding positioning grooves to complete the assembly, without additional tools or complex steps. During the folding process, the positioning protrusions can slide in the positioning grooves, thus achieving a smooth and unobstructed folding action. When the mosquito net needs to be unfolded, the tight fit between the positioning protrusions and the positioning groove helps to quickly return to the open state, improving the user experience.

[0014] Further, the positioning member includes a pin shaft, and limiting members are riveted to both ends of the pin shaft.

[0015] By adopting the above technical solution, the pin shaft, as a rigid connecting member, can provide a more stable connection than elastic materials. By fixing the pin shaft between the first sleeve and the second sleeve, a tight connection between the two parts is ensured. The use of the limiting member further restricts the movement range of the pin shaft and prevents it from disengaging from the positioning groove, thereby enhancing the stability of the entire structure. The pin shaft is usually made of metal or other high-strength materials, having good tensile strength and durability, and can withstand repeated folding and unfolding operations without being easily damaged. The riveted limiting member increases the firmness of the pin shaft, reduces the wear or loosening problems caused by frequent use, and extends the service life of the product.

[0016] Further, a relief notch penetrating the connection end is provided in the vertical direction of the connection end, and the elastic connecting member passes through the relief notch.

[0017] By adopting the above technical solution, the relief notch provides necessary movement space for the elastic connecting member, allowing it to freely expand and contract during the folding and unfolding processes. This design increases the flexibility of the entire structure, enabling the mosquito net skeleton to be folded more smoothly. Through the relief notch, the elastic connecting member can easily pass through and be fixed in place without complex installation steps or additional tools. This simplifies the assembly process and improves user convenience. Just pass the elastic connecting member through the notch and then fix its two ends to the first sleeve and the second sleeve to complete the assembly. The relief notch reduces the direct friction between the elastic connecting member and the sleeve, reducing the risk of wear, and thus extending the service life of the elastic connecting member. Since the elastic connecting member can move freely within the notch, damage caused by excessive stretching is avoided.

[0018] The utility model further includes a mosquito net, a foldable skeleton connecting device, a bracket, and a mosquito net cloth. The mosquito net cloth is sleeved on the bracket, and the brackets are connected through the foldable connecting skeleton.

[0019] The utility model has the following beneficial effects:

[0020] 1. The design of the utility model enables the mosquito net skeleton to be folded and unfolded quickly and smoothly. The cooperation between the elastic connecting member and the relief notch provides necessary movement space, allowing the skeleton to be folded smoothly. When unfolded, the automatic opening function of the elastic connecting member ensures that the skeleton can quickly return to the fully unfolded state. This efficient operating performance significantly improves the user experience. Especially during outdoor activities, users can set up and put away the mosquito net more conveniently and quickly without cumbersome operations.

[0021] 2. The utility model simplifies the assembly and maintenance processes significantly through the design of providing a relief notch at the connection end and enabling the elastic connecting piece to pass through this notch. The assembly can be completed simply by passing the elastic connecting piece through the relief notch and fixing it in the corresponding limiting groove or limiting hole, without the need for additional tools or complex steps. If component replacement or repair is required, it only involves simply disassembling the riveted limiting piece and removing the elastic connecting piece, greatly reducing the maintenance difficulty and cost.

[0022] 3. The utility model ensures a tight connection between the two sleeve parts by using an elastic connecting piece between the first sleeve and the second sleeve and combining the design of the positioning groove and the positioning piece (such as a positioning protrusion or a pin shaft), reducing looseness or misalignment caused by external forces. The movement range of the pin shaft is further restricted by the limiting piece to prevent it from disengaging from the positioning groove. The free expansion and contraction of the elastic connecting piece within the relief notch reduce wear and extend the service life of the entire device. BRIEF DESCRIPTION OF THE DRAWINGS

Then, snap the positioning member 121 into the positioning groove 111. When folding is required, first pull the second sleeve 12. The positioning member 121 of the second sleeve 12 slides in the positioning groove 111. When the positioning member 121 slides to the end of the positioning groove 111, rotate the second sleeve 12 to fold the foldable skeleton connecting device. When it is necessary to open the foldable skeleton connecting device, the first sleeve 12 and the second sleeve 11 return to the initial position under the action of the elastic connecting member 2.

[0032] As Figure 2 and Figure 3 shown, it can be seen that a limiting groove one 112 is provided at one end of the first sleeve 11, and a limiting groove two 122 is provided at one end of the second sleeve 12.
