Description

Technical Field

[0001] This utility model relates to the field of mosquito net technology, and in particular to a mosquito net support frame that prevents mosquitoes from falling off. Background Technology

[0002] A typical mosquito net is a screen hung on a bed frame to prevent mosquito bites and also to absorb dust from the air. The use of mosquito nets is an indispensable part of daily life. Most existing mosquito nets are set up using a frame.

[0003] Currently, mosquito net frame sets on the market consist of multiple support poles connected to each other via T-joints. However, the T-joints used in this market have a simple structure, with the support poles typically inserted directly into the T-joint interface without any locking mechanism. This plug-in connection method makes the mosquito net poles prone to loosening or slipping during use due to shaking or pulling, affecting the overall stability and lifespan.

[0004] Therefore, there is a need to provide a mosquito net support frame that prevents mosquitoes from falling off to solve the above problems. Utility Model Content

[0005] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an anti-slip mosquito net bracket. During assembly, the support rod is inserted into the corresponding T-connector and locked to ensure that there is no slippage between the support rod and the T-connector, thus ensuring the overall stability of the mosquito net bracket and improving its service life.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a mosquito net support frame that prevents mosquito netting from falling off, comprising multiple support rods and multiple T-connector pipes; the support rods arranged horizontally, vertically, and laterally are connected by a T-connector pipe to form a mosquito net support structure that can support the mosquito net. The T-connector pipe includes three connecting branches, and the inner wall of each connecting branch pipe can be provided with at least one boss or locking groove along the insertion direction of the support rod. The outer periphery of each support rod at both ends along its length direction can be provided with at least one locking groove or boss that engages with the boss or locking groove.

[0007] Furthermore, the first boss and the second locking groove are arranged in a ring shape, and both surfaces are set as arc surfaces. When the support rod is inserted into the connecting pipe, the first boss can be directly inserted into the second locking groove, thereby fixing the support rod and the connecting pipe together, which is simple to operate.

[0008] Furthermore, the first locking groove includes an extension section and an abutment section arranged sequentially along the direction close to the support rod. When the support rod is inserted into the connecting pipe and locked therein, at least part of the outer periphery of the second boss on it abuts against the abutment section. The right side of the second boss acts as a stop, forming a mechanical limit and effectively preventing the support rod from easily coming out of the connecting pipe due to external force after insertion.

[0009] Furthermore, the diameter of the extended section of the snap-fit ​​groove gradually decreases from the direction close to the support rod to the direction away from the support rod until it matches the inner diameter of the connecting branch pipe.

[0010] Furthermore, the end of the connecting pipe near the support rod is provided with several notches along its circumference, and the notches extend to the end of the connecting pipe and divide the end of the connecting pipe into several elastic claws. The boss or the snap-fit ​​groove is provided on the elastic claw.

[0011] Specifically, several notches are spaced circumferentially along the connecting branch pipe, and the opening direction of the notch is parallel to the straight line along the length direction of the connecting branch pipe. The end of the connecting branch pipe is divided into multiple sheet-like structures by the notches. The sheet-like structures are more likely to bend or deform when subjected to external force, thus exhibiting elasticity, i.e., forming elastic claw plates.

[0012] Furthermore, it also includes a locking cover, which is hollow inside and has a through opening in the middle for the end of the support rod to be inserted. The inner wall of the locking cover is provided with an internal thread, and the connecting pipe is provided with an external thread that matches the internal thread. The locking cover can be screwed and fixed to the connecting pipe to cover and press the pipe opening area of ​​the connecting pipe.

[0013] Both ends of the support rod along its length are fitted with locking caps so that each end can be locked to a connecting branch on a T-connector. After the locking caps are screwed and locked to the connecting branch, they grip the opening of the connecting branch, further locking the position of the support rod and the connecting branch. This ensures smooth installation while achieving a firm lock, making it suitable for mass production of plastic parts. It has a reliable structure, long service life, and can effectively prevent the structure from loosening due to material loosening or deformation, further ensuring the stability of the mosquito net frame assembly and effectively preventing detachment.

[0014] Furthermore, the connecting pipe includes an integrally formed fixing part and a connecting part. The outer diameter of the connecting part is smaller than the outer diameter of the fixing part. The external thread and several notches are all located on the connecting part and are arranged sequentially in the direction toward the support rod.

[0015] Furthermore, the inner wall of the locking cover includes a threaded section and a tightening section. The tightening section is inclined from the end of the threaded section toward the through opening, so that the tightening section and the through opening are in a constricted shape. The diameter of the inside of the locking cover gradually decreases from the threaded section toward the through opening, so that when the locking cover is locked with the connecting pipe, the locking force of the locking cover on the connecting pipe becomes larger and larger, further gripping the elastic claw plate on the support rod.

[0016] The beneficial effects of this utility model are:

[0017] In this utility model, the support rod, the three-way connecting pipe, the first boss, the second boss, the first snap-fit ​​groove, and the second snap-fit ​​groove cooperate with each other. The snap-fit ​​setting of the concave and convex structure ensures that the support rod will not easily detach from the connecting pipe due to external force, ensuring that there will be no slippage between the support rod and the three-way connecting piece, ensuring the overall stability of the mosquito net frame, and improving the service life of the mosquito net frame.

Detailed Implementation

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0027] See appendix Figures 1 to 7As shown, a mosquito net support frame in this embodiment includes multiple support rods 1 and multiple T-connector pipes 2. The support rods 1 arranged horizontally, vertically, and laterally are connected by a T-connector pipe 2 to form a mosquito net support frame structure that can support the mosquito net. The T-connector pipe 2 includes three connecting branches 21. The inner wall of each connecting branch pipe 21 can be provided with at least one boss 3 or a locking groove 4 along the insertion direction of the support rod 1. The outer periphery of each support rod 1 at both ends along its length direction can be provided with at least one locking groove 5 or boss 9 that locks with the boss 3 or locking groove 4.

[0028] During assembly, the support rod 1 is inserted into the corresponding tee connector. The boss 3 on the inner wall of each connecting branch pipe 21 can engage with the corresponding snap-fit ​​groove 5 on the support rod 1, or the snap-fit ​​groove 4 on the inner wall of each connecting branch pipe 21 can precisely engage with the corresponding boss 9 on the support rod 1. The cooperation of the concave and convex structure ensures that the support rod 1 will not easily detach from the connecting branch pipe 21 due to external force, ensuring that there will be no slippage between the support rod 1 and the tee connector, ensuring the overall stability of the mosquito net frame, and thus improving the service life of the mosquito net frame.

[0029] In some embodiments, one, two, or all three connecting pipes may be provided with a boss or a snap-fit ​​groove.

[0030] See appendix Figures 1 to 3 The first boss 3 and the second snap-fit ​​groove 5 are arranged in a ring shape, and both surfaces are set as arc surfaces. When the support rod 1 is inserted into the connecting pipe 21, the first boss 3 can be directly snapped into the second snap-fit ​​groove 5, thereby fixing the support rod 1 and the connecting pipe 21 together, which is simple to operate;

[0031] The surfaces of the boss 3 and the snap-fit ​​groove 5 are made into arc surfaces, which makes it easier for the boss 3 to snap into or out of the snap-fit ​​groove 5, and facilitates the assembly and disassembly of the mosquito net frame.

[0032] In some embodiments, a boss 3 and a snap-fit ​​groove 5 are respectively provided around the end of the connecting pipe 21 and the support rod 1. The boss 3 protrudes from the inner wall of the connecting pipe 21, while the snap-fit ​​groove 5 is recessed toward the central axis of the support rod 1.

[0033] In other embodiments, two, three, or four bosses 3 are spaced apart along the length of the connecting branch pipe 21, and multiple bosses 3 are spaced apart. One snap-fit ​​groove 5 is provided, and a slot of sufficient length for the support rod 1 to be inserted is provided in the connecting branch pipe 21. Depending on the different depths to which the support rod 1 is inserted into the connecting branch pipe 21 and snapped with it, the internal space of the mosquito net frame can be expanded or reduced, so that the mosquito net frame can be adapted to different sizes of venues and effectively improve its applicability.

[0034] The snap-fit ​​groove 4 includes an extension section 12 and an abutment section 13 arranged sequentially along the direction close to the support rod 1. When the support rod 1 is inserted into the connecting pipe 21 and snaps into it, at least part of the outer periphery of the boss 29 on it abuts against the abutment section. The boss 29 is stopped from the right side, forming a mechanical limit and effectively preventing the support rod 1 from easily coming out of the connecting pipe 21 due to external force.

[0035] See appendix Figures 5 to 7 The diameter of the extended section of the snap-fit ​​groove 4 gradually decreases from the direction close to the support rod 1 to the direction away from the support rod 1 until it matches the inner diameter of the connecting branch pipe 21.

[0036] In some embodiments, the extension section and the abutment section on the snap-fit ​​groove 4 are symmetrically arranged, and the two are combined to form an arc-shaped space into which the protrusion 9 with an arc-shaped surface is snapped.

[0037] In other embodiments, the diameter of the extension 12 on the snap-fit ​​groove 4 remains unchanged from the direction near the support rod 1 to the direction away from the support rod 1, and the abutment section is inclined to the right and downward from the junction with the extension section toward the direction near the support rod 1 to form a snap-fit ​​structure that prevents the boss 29 on the support rod 1 from disengaging from the connecting pipe 21.

[0038] See appendix Figures 1 to 7 The connecting branch pipe 21 has several notches 6 along its circumference at one end near the support rod 1. The notches 6 extend to the end of the connecting branch pipe 21 and divide the end of the connecting branch pipe 21 into several elastic claw pieces 7. The boss 3 or the snap-fit ​​groove 4 is provided on the elastic claw piece 7.

[0039] Specifically, several notches 6 are spaced circumferentially along the connecting branch pipe 21, and the opening direction of the notches 6 is parallel to the straight line along the length direction of the connecting branch pipe 21. The end of the connecting branch pipe 21 is divided into multiple sheet-like structures by the notches 6. The sheet-like structures are more likely to bend or deform when subjected to external force, thus exhibiting elasticity, i.e., forming elastic claw plates 7.

[0040] When the elastic claw plate 7 is provided with a boss 3 and the support rod 1 is provided with a corresponding snap-fit ​​groove 5, the support rod 1 is inserted into the corresponding connecting pipe 21. The elastic claw plate 7 is in an open state under its own elasticity, which makes it convenient for the support rod 1 to open and insert the end of the connecting pipe 21. After the support rod 1 is fully inserted and snapped into the connecting pipe 21, the elastic claw plate 7 rebounds and clamps it along the circumference of the support rod 1.

[0041] When the elastic claw plate 7 is provided with a locking groove 4 and the support rod 1 is provided with a corresponding boss 9, the locking groove 4 makes the inner wall of the elastic claw plate 7 near the support rod 1 form a protruding limiting boss structure. After the support rod 1 is inserted, the locking groove 4 and the limiting boss structure combine to lock the boss 9 on the support rod 1, so that the support rod 1 will not easily separate from the connecting pipe 21 under the action of external force. The elastic claw plate 7 in the rebound state initially holds the support rod 1 tightly along the circumference, further preventing the support rod 1 from separating from the connecting pipe 21.

[0042] It should be noted that the number of elastic claw pieces 7 that the connecting pipe 21 ends are divided into by several notches 6 is not limited.

[0043] It also includes a locking cover 10, which is hollow inside and has a through opening in the middle for inserting the end of the support rod 1. The inner wall of the locking cover 10 is provided with an internal thread 11, and the connecting pipe 21 is provided with an external thread 8 that matches the internal thread 11. The locking cover 10 can be screwed and fixed to the connecting pipe 21 to cover and press the pipe opening area of ​​the connecting pipe 21.

[0044] Both ends of the support rod 1 along its length are fitted with a locking cap 10 so that each end can be locked to the connecting branch pipe 21 on a three-way connecting pipe 2. After the locking cap 10 is screwed and locked to the connecting branch pipe 21, it clamps the opening of the connecting branch pipe 21, further locking the position of the support rod 1 and the connecting branch pipe 21. While ensuring smooth installation, it achieves a firm lock, is suitable for mass production of plastic parts, and has a reliable structure and long service life. It can effectively prevent the structure from loosening due to material loosening or deformation, further ensuring the stability of the mosquito net frame assembly and effectively preventing detachment.

[0045] In some embodiments, the locking cover 10 can also be provided with a limiting point, and the surface of the connecting pipe 21 is provided with a limiting groove to facilitate the locking point to be engaged, which can also achieve the clamping of the insertion part of the support rod 1 and the three-way connecting pipe 2.

[0046] It should be noted that the locking cover 10 locks the support rod 1 and the three-way connecting pipe 2 in a manner that is not limited to the two methods mentioned above. Other known mechanical structures can also be used, which will not be elaborated here.

[0047] The connecting pipe 21 includes an integrally formed fixing part 211 and a connecting part 212. The outer diameter of the connecting part is smaller than the outer diameter of the fixing part. The external thread 8 and several notches 6 are located on the connecting part and are arranged sequentially in the direction toward the support rod 1. The connecting part is designed with an outer diameter smaller than that of the fixing part so that after the locking cover 10 is screwed on and locked, the outer periphery of the locking cover 10 will not protrude too much from the outer periphery of the fixing part 211, making the overall appearance of the mosquito net support frame more aesthetically pleasing.

[0048] The inner wall of the locking cover includes a threaded section 101 and a tightening section 102. The tightening section is inclined from the end of the threaded section toward the through opening, so that the tightening section and the through opening are in a constricted shape. The diameter of the inside of the locking cover gradually decreases from the threaded section toward the through opening, so that when the locking cover is locked with the connecting pipe, the locking force of the locking cover on the connecting pipe becomes larger and larger, further gripping the elastic claw plate on the support rod.

[0049] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
