Description

Technical Field

[0001] This utility model belongs to the field of daily necessities, specifically relating to a fastener, a stable mosquito net bracket, and a mosquito net. Background Technology

[0002] Mosquito nets, as common household items used for mosquito prevention, typically require a foldable and easy-to-store frame structure, hence the widespread use of bendable tent poles. Currently, bendable tent poles are mostly composed of multiple connecting rods. The connection structure at these joints directly affects the overall stability and lifespan of the tent pole. Traditional tent pole splicing methods mainly employ simple interlocking, snap-fit, or threaded connections. Interlocking structures rely solely on interference fits between the connecting rods for connection, making them prone to loosening under frequent bending or stress, and even detachment due to deformation, indicating insufficient connection strength.

[0003] Chinese Patent No. CN201347629Y discloses a folding joint for tent and mosquito net poles, belonging to the technical field of tent and mosquito net accessories. It comprises a U-shaped sleeve, a steering head, a screw, a nut, and a plug. The U-shaped sleeve includes a U-shaped groove, a pivot hole, and a plug hole. The steering head includes a rotating head and a plug hole, with an elongated waist-shaped hole at the upper end of the rotating head. The U-shaped sleeve and the steering head are hinged together by a screw that passes axially through the pivot hole and the waist-shaped hole and is secured with a nut. This invention provides a folding joint for tent and mosquito net poles with multiple locking points, a strong and stable locking device, and an aesthetically pleasing and compact design. It solves the technical problems of existing technologies, such as few locking points, low strength of the locking device, a clumsy overall joint design, and the locking device being easily damaged or broken, leading to instability or unusability of the entire mosquito net or tent. The aforementioned devices have low strength at the splicing points of the mosquito net poles, and the locking and unlocking operations rely on screws or fasteners, requiring manual tightening or the application of tools. Therefore, it is imperative for those skilled in the art to solve the aforementioned technical problems. Utility Model Content

[0004] This invention is used to solve the above-mentioned technical problems and improve the connection strength at the joints of the horizontal or vertical poles of mosquito nets.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A fastener for strengthening the connection strength of splicing rods in a bendable tent pole, the fastener comprising a connecting part and a locking part;

[0007] The connecting part is a through structure, with its two ends used to connect two sections of connecting rods to be spliced, and the outer wall of the connecting part is provided with a limiting groove;

[0008] The locking part includes a locking sleeve and a locking snap that is rotatably mounted on the locking sleeve. The locking sleeve is sleeved on one end of the connecting part. One end of the locking snap engages with the limiting groove. The connecting rod can be locked or unlocked by pressing the locking snap.

[0009] By adopting the above technical solution, the connecting part has a through structure. The two connecting rods at the beginning and end are connected to the locking sleeve of the locking part, which is sleeved on one end of the connecting part. The locking snap can be rotatably installed on the locking sleeve. Through the snap engagement between the locking snap and the limiting groove of the connecting part, the stable connection of the two connecting rods is ensured, avoiding the problem of easy loosening of traditional sleeves. It also simplifies the disassembly and assembly steps without the need for tools, and achieves a balance between connection strength and ease of operation.

[0010] Furthermore, one end of the locking snap is provided with a connecting protrusion, the connecting protrusion is sleeved in the spring, and the spring is fixed to the outer wall of the locking sleeve;

[0011] The other end of the locking snap is provided with a limiting protrusion extending along its height direction. The bottom of the limiting protrusion is provided with an inwardly recessed arc-shaped groove. The arc-shaped groove is adapted to the shape of the outer wall of the connecting part. The limiting protrusion is engaged with the limiting groove through the arc-shaped groove.

[0012] By adopting the above technical solution, the spring sleeved on the outer wall of the locking sleeve and the connecting protrusion of the locking snap fit into the limiting groove of the connecting part through the elastic restoring force of the spring, the locking snap can automatically reset after being pressed and tightly engage with the limiting groove to avoid accidental loosening; at the same time, the design of the arc groove matching the shape of the outer wall of the connecting part increases the engagement contact area and further improves the connection reliability in the locked state.

[0013] Furthermore, the side wall of the locking sleeve is provided with a snap fastener mounting groove, and the two side walls of the snap fastener mounting groove are symmetrically provided with locking sleeve positioning holes; the two side walls of the locking snap fastener are correspondingly provided with positioning protrusions, and the positioning protrusions engage with the positioning holes of the locking sleeve to realize the rotatable installation of the locking snap fastener on the locking sleeve.

[0014] By adopting the above technical solution, the locking sleeve positioning holes on both sides of the locking sleeve's snap mounting groove are engaged with the positioning protrusion of the locking snap, providing a rotatable mounting fulcrum for the locking snap. This ensures that the locking snap can rotate precisely around the positioning hole of the locking sleeve when pressed, avoiding displacement. This makes the engagement / disengagement action of the limiting protrusion and the limiting groove more stable and the operation process smoother.

[0015] Furthermore, both the connecting part and the locking part are provided with a through mounting sleeve inside, and the mounting sleeve is fixed to the inner wall of the connecting part and the locking part respectively; the mounting sleeve of the connecting part and the mounting sleeve of the locking part are sleeved and connected to each other, and the inner wall of the mounting sleeve is adapted to the outer wall of the connecting rod.

[0016] By adopting the above technical solution, the mounting sleeves inside the connecting part and the locking part are fixed to their inner walls and interlocked with each other for assembly with the connecting rod. Through the matching design of the inner wall of the mounting sleeve and the outer wall of the connecting rod, the connecting rod is tightly fitted with the fixing part without any shaking gap after insertion, which effectively enhances the anti-torsion and anti-bending ability of the splice and further improves the overall connection strength of the tent pole.

[0017] Furthermore, the opening of the mounting sleeve faces outwards from the connecting portion and the locking portion, respectively, to accommodate the insertion and installation of the connecting rod.

[0018] By adopting the above technical solution, the assembly design with the sleeve opening facing the outside of the connecting part and the locking part allows the connecting rod to be directly inserted into the mounting sleeve from the outside of both ends of the fixing part without adjusting the angle or additional alignment. This simplifies the assembly steps of the connecting rod and the fixing part and improves the installation efficiency in actual use.

[0019] This utility model also discloses a stable mosquito net support frame, including a bendable tent pole formed by splicing at least two connecting rods, with adjacent connecting rods connected by fasteners; the cross-sectional shape of the tent pole is a round tube, a flat tube, or a square tube, and the connecting part of the fastener is adapted to the cross-sectional shape of the corresponding tent pole, with adjacent tent poles connected together by corner tees.

[0020] By adopting the above technical solution, the assembly of the bendable tent poles and fasteners of the mosquito net frame avoids the problem of traditional fasteners needing to be customized for tent poles with different cross-sections through the universal compatibility of the fasteners with round tubes, flat tubes, and square tubes, thus reducing production and replacement costs. At the same time, the locking structure of the fasteners strengthens the joint strength, making the frame more stable and less prone to loosening due to bending under force.

[0021] Furthermore, the vertically arranged connecting rod is provided with at least two positioning holes, and the two vertically arranged connecting rods are connected together by a limiting member. The limiting member includes a sleeve, on which a limiting snap is installed, and at the bottom of the limiting snap is a limiting post, which is adapted to the positioning hole.

[0022] By adopting the above technical solution, the assembly of springs between adjacent tent poles allows the elastic deformation of the springs to absorb some of the stress when the poles are bent, and the spring's rebound force helps the poles return to a straight state when they are reset. This not only extends the service life of the tent poles but also makes the bending operation easier and less strenuous.

[0023] This utility model also discloses a mosquito net, including a mosquito net frame and a mosquito net fabric fitted onto the mosquito net frame.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model uses a central connecting part to connect two connecting rods and a locking part at both ends. A locking sleeve is fitted onto one end of the connecting part, and a locking snap is rotatably installed on the locking sleeve. Combined with the snap-fit ​​between the locking snap and the limiting groove of the connecting part, it not only ensures the stable connection of the two connecting rods and avoids the problem of easy loosening in traditional sleeves, but also simplifies the disassembly and assembly steps without the need for tools, thus achieving a balance between connection strength and ease of operation.

[0026] 2. This utility model uses a spring that is sleeved on the outer wall of the locking sleeve and fits into the arc-shaped groove at the bottom of the limiting protrusion to connect the limiting groove of the connecting part. The elastic restoring force of the spring ensures that the locking button automatically resets after being pressed and tightly engages with the limiting groove to prevent accidental loosening. At the same time, the design of the arc-shaped groove adapting to the outer wall of the connecting part increases the engagement contact area, further improving the connection reliability in the locked state.

[0027] 3. This utility model uses mounting sleeves inside the connecting part and the locking part to be fixed to the inner walls of the two parts respectively and to be fitted together with the connecting rod. With the adaptation design of the inner wall of the mounting sleeve and the outer wall of the connecting rod, the connecting rod is tightly fitted with the fixing part after insertion without any shaking or gap, which effectively enhances the anti-torsion and anti-bending ability of the splice and further improves the overall connection strength of the tent pole.

[0028] 4. This utility model avoids the problem of traditional fasteners needing to be customized for tent poles with different cross-sections by adapting the fastener connection part to the tent poles with different cross-sections, thus reducing production and replacement costs. At the same time, the locking structure of the fastener strengthens the joint strength, making the bracket more stable as a whole and less prone to loosening due to bending under force.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

[0042] In the description of this utility model, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this utility model. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the protection scope of this utility model.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, a fastener, a stable mosquito net bracket, and a mosquito net are disclosed. The fastener 10, as the core connecting component, consists of a connecting part 11 and a locking part 12. The connecting part 11 has a through-hole structure, with its two ends used to insert and connect two connecting rods 211 to be spliced. A locking groove 112 is provided on the outer wall for locking. The locking sleeve 121 of the locking part 12 is sleeved on one end of the connecting part 11. A snap fastener mounting groove 121a is provided on its side wall. The two side walls of the groove are symmetrically provided with locking sleeve positioning holes 121b, which engage with the positioning protrusions 122d on the two side walls of the locking snap fastener 122, so that the locking snap fastener 122 can be wrapped around the locking sleeve. The positioning hole 121b is rotatably installed on the locking sleeve 121; the connecting protrusion 122a at one end of the locking snap 122 is sleeved in the spring 123 fixed on the outer wall of the locking sleeve 121, and the bottom of the limiting protrusion 122b extending along the height direction at the other end is provided with an arc-shaped groove 122c that matches the shape of the outer wall of the connecting part 11. The groove fits and engages with the limiting groove 112 of the connecting part 11. When the locking snap 122 is pressed, it rotates around the positioning hole 121b of the locking sleeve, causing the limiting protrusion 122b to disengage from or engage with the limiting groove 112. The elastic restoring force of the spring 123 is used to lock or unlock the connecting rod 211. In addition, the inner walls of the connecting part 11 and the locking part 12 are both fixed with through mounting sleeves 111. The two are connected to each other, and the inner wall of the mounting sleeve 111 is adapted to the outer wall of the connecting rod 211. Its openings face the outer side of the connecting part 11 and the locking part 12 respectively, guiding the connecting rod 211 to be inserted from the outer side of both ends and fit tightly, thereby enhancing the stability of the splice.

[0044] In the stable mosquito net frame 20, the bendable tent pole 21 is formed by splicing at least two connecting rods 211 together through the aforementioned fastener 10. The connecting part 11 of the fastener 10 is designed to fit the cross-sectional shape of the tent pole's round, flat, or square tube. Adjacent tent poles 21 are connected by corner tees 22 to form a frame. Simultaneously, springs 123 are installed between adjacent connecting rods 211. When the tent pole is bent, the elastic deformation of the springs 123 absorbs stress, and when it returns to its original position, the rebound force of the springs 123 assists in restoring it to a straight state. Finally, the mosquito net 30 forms a complete mosquito-proof structure by fitting the mosquito net fabric onto the mosquito net frame 20.

[0045] In one embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As can be seen, in use, the two connecting rods 211 to be spliced ​​are first inserted into the openings of the mounting sleeves 111 on the outside of the connecting part 11 and the locking part 12, respectively. Since the inner wall of the mounting sleeve 111 is adapted to the outer wall of the connecting rod 211, the connecting rod 211 fits tightly with the fixing part 10 after insertion, without any shaking or gap. At this time, the locking sleeve 121 of the locking part 12 is sleeved on one end of the connecting part 11, and the locking snap 122 is engaged with the locking sleeve positioning hole 121b of the snap mounting groove 121a of the locking sleeve 121 through the positioning protrusions 122d on both sides, so as to achieve rotatable installation.

[0046] When it is necessary to lock the connecting rod 211, press the end of the locking snap 122 away from the limiting groove 112. The locking snap 122 rotates around the positioning hole 121b of the locking sleeve, and the limiting protrusion 122b at the other end swings downward. The arc-shaped groove 122c at the bottom fits and engages with the limiting groove 112 on the outer wall of the connecting part 11. At the same time, the connecting protrusion 122a at one end of the locking snap 122 compresses the spring 123 sleeved on it. The elastic restoring force generated by the spring 123 makes the limiting protrusion 122b tightly abut against the limiting groove 112, preventing accidental loosening and completing the locking of the connecting rod 211, ensuring a stable connection at the splice.

[0047] When unlocking is required, press the locking snap 122 again, which rotates in the opposite direction around the locking sleeve positioning hole 121b. The limiting protrusion 122b swings upward and disengages from the limiting groove 112, the spring 123 resets, and the locking snap 122 returns to its initial state. At this time, the connecting rod 211 can be pulled out from the mounting sleeve 111 to complete the unlocking.

[0048] The entire process involves pressing the locking snap 122 to quickly switch between locking and unlocking without the need for tools. Meanwhile, the tight fit of the mounting sleeve 111, the increased contact area of ​​the arc groove 122c and the limiting groove 112, and the elastic return design of the spring 123 together ensure the connection strength and ease of operation of the fastener 10 and the connecting rods 211.

[0049] In one embodiment, refer to Figure 7It is understood that the bendable tent pole 21 of the mosquito net frame is composed of multiple connecting rods 211 spliced ​​together, with springs 123 installed between adjacent connecting rods 211. When the tent pole needs to be bent, the connecting rod 211 bends with the splice point as the fulcrum. At this time, the spring 123 simultaneously undergoes elastic deformation, stretching or compressing, absorbing part of the stress when the connecting rod 211 is bent, avoiding metal fatigue or breakage caused by direct force concentration. When it needs to be reset, the spring 123 assists the connecting rod 211 to return to a straight state through its own rebound force, making bending and reset operations easier and less strenuous, while extending the service life of the tent pole. Adjacent connecting rods 211 are connected by fasteners 10. The inner wall of the mounting sleeve 111 inside the connecting part 11 and the locking part 12 is adapted to the outer wall of the connecting rod 211. After the connecting rod 211 is inserted, there is no wobbling gap between it and the mounting sleeve 111, enhancing the anti-torsion and anti-bending capabilities at the splice point. The bottom arc-shaped groove 122c of the limiting protrusion 122b of the locking snap 122 fits and engages with the limiting groove 112 on the outer wall of the connecting part 11, increasing the contact area. Combined with the elastic restoring force of the spring 123, the spring 123 sleeved on the connecting protrusion 122a provides a continuous abutting force, ensuring that the limiting protrusion 122b and the limiting groove 112 are tightly fitted in the locked state, preventing accidental loosening. The connecting part 11 of the fastener 10 is designed to adapt to the cross-sectional shape of the tent pole's round tube, flat tube, and square tube, avoiding loosening of the connection due to cross-sectional differences, and further improving the stability of the splicing. The elastic assistance of the spring 123 and the multiple locking structure of the fastener 10 together realize the flexible bending of the tent pole and the high stability of the splicing.

[0050] In one embodiment, refer to Figure 6 , Figure 8 and Figure 9 It is known that the vertically arranged connecting rod 211 of the mosquito net 30 is provided with four positioning holes 2111. Two connecting rods 211 are connected and positioned together by limiting member 23. The two connecting rods 211 are sleeved together, and the distance between the positioning holes 2111 is 10cm. The height of the mosquito net can be adjusted by adjusting the distance between the two connecting rods 211. When adjusting, first press the limiting snap 231 to separate the limiting post 2311 from the positioning hole 2111. Stretch the connecting rod 211 to stretch or shorten the distance between the two connecting rods 211. Release the limiting snap 231 to reassemble the limiting post 2311 and the positioning hole 2111 together to achieve the positioning of the connecting rod 211.

[0051] Working principle: The fixing part 10 serves as the core connecting component. Through the cooperation of the connecting part 11 and the locking part 12, the connecting rod 211 can be quickly connected and separated. During initial installation, the two sections of the connecting rod 211 to be joined are inserted into the openings of the mounting sleeves 111 on the outside of the connecting part 11 and the locking part 12, respectively. Because the inner wall of the mounting sleeve 111 matches the outer wall of the connecting rod 211, the connecting rod 211 fits tightly against the fixing part 10 after insertion, without any shaking or gap, forming a basic connection. When locking, pressing the locking snap 122 of the locking part 12 at the end away from the limiting groove 112 causes the locking snap 122 to rotate around its axis through the engagement fulcrum of the positioning protrusions 122d on both sides and the positioning hole 121b of the locking sleeve 121. The limiting protrusion 122b at the other end swings downward, and the arc-shaped groove 122c at the bottom fits and engages with the limiting groove 112 on the outer wall of the connecting part 11. At the same time, the spring 123, which is compressed and sleeved on the connecting protrusion 122a at one end of the locking snap 122, is locked. The elastic restoring force of the spring 123 keeps the limiting protrusion 122b tightly against the limiting groove 112 to prevent accidental loosening, thus locking the connecting rod 211 and ensuring the stability of the splice. When unlocking, press the locking snap 122 again to make it rotate in the opposite direction around the positioning hole 121b of the locking sleeve. The limiting protrusion 122b swings upward and disengages from the limiting groove 112. The spring 123 returns to its original state, and the locking snap 122 returns to its initial state. At this time, the connecting rod 211 can be pulled out to complete the unlocking. Meanwhile, the bendability and stability of the mosquito net frame 20 are achieved through the following collaborative design: when the tent pole 21 needs to be bent, the adjacent connecting rods 211 bend with the splice of the fastener 10 as the fulcrum, and the springs 123 set between the connecting rods 211 simultaneously elastically deform and stretch or compress, absorbing bending stress to avoid fatigue or breakage of the connecting rods; after the external force is removed, the springs 123 assist the connecting rods 211 to return to a straight state through the rebound force, reducing manual force application; in terms of stability, the tight fit design of the mounting sleeve 111 of the fastener 10 avoids the shaking of the connecting rods, the increased contact area of ​​the locking snap 122 and the limiting groove 112 enhances the locking strength, and the adaptation design of the connecting part 11 to round tubes, flat tubes or square tubes avoids loosening caused by cross-sectional differences, together ensuring high stability at the splice, so that the frame as a whole is not easy to loosen when bent or under stress.

[0052] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solution of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
