Description

Technical Field

[0001] This utility model relates to the field of mosquito net support technology, and in particular to a novel mosquito net easy-to-install structure. Background Technology

[0002] In the sweltering summer, mosquitoes are plentiful and bother people, especially children whose skin is delicate. If they are bitten by mosquitoes while sleeping, they will suffer from large areas of redness and swelling. Therefore, families choose to install mosquito nets above their beds to block mosquitoes at night.

[0003] The oldest method of installing mosquito nets involves attaching vertical poles at the corners of the bed and securing the net to the ends of the poles. This method often results in the net tilting due to insecure pole installation. Subsequently, integrated fixed mosquito net mounting brackets were designed, but these take up space and cannot be stored. Detachable mounting brackets have become the preferred choice, and most of the current market uses this type of bracket. Various poles are connected to form a cuboid mounting structure, which is fixed around the perimeter of the bed, and the mosquito net is then fixed to the horizontal pole at the top. However, some current mounting brackets require spiral connections between the poles, which does not meet the requirement of convenient installation.

[0004] To make the frame more robust, support feet are installed at the lower end of the cuboid mounting structure. These support feet are designed as pressure plates extending horizontally from the vertical members of the cuboid, with the angles of the pressure plates pointing towards the center of the bed. During use, the pressure plates press down on the mattress, effectively securing the mounting structure. Because mattress thickness varies, the height of the support feet needs to be adjusted accordingly. Currently, some mosquito net mounting frames lack adjustment functionality. Adjustable mosquito net mounting frames primarily use threaded, screw-type, beaded, or push-button adjustment mechanisms. These adjustment methods all have significant drawbacks. For example, with threaded mechanisms, height adjustment is only discovered after installation, requiring the rotation of the rods and necessitating the removal of the rotating parts. Adjusting the height of a mosquito net before reinstalling it creates a lot of repetitive work. Furthermore, the height is difficult to control during rotation. Screw-type adjustments require aligning the positioning holes on the rods before screwing them in, and these screws often disappear during disassembly, causing significant inconvenience. The removed screws are also difficult to store. Adjustment beads are more convenient; simply press the bead while pushing or pulling the rod. However, the bead has very low load-bearing capacity and easily loosens with minimal force, causing the adjustment function to malfunction. Press-type adjustments are simple and easy to use, but repeated pressing, excessive force, and structural aging can cause the internal spring to push out the pressing part, damaging the pressing area. These various issues make the convenience and durability of the height adjustment function in the mosquito net's connection structure the most important concerns for consumers.

[0005] The above problems urgently need to be addressed. Utility Model Content

[0006] The main purpose of this utility model is to provide a new type of convenient mosquito net installation structure, which aims to achieve portable installation of the mosquito net installation structure and convenient and quick adjustment of the required height of the installation structure.

[0007] This utility model proposes a novel convenient mosquito net installation structure, including a lower fixed frame and an upper support frame connected to the lower fixed frame. The lower fixed frame includes multiple height-adjustable support components and connecting rods connected between adjacent support components. Each support component includes a support foot with a vertically mounted vertical rod, a fixed rod, and a connector. The connector has a vertically penetrating connecting hole adapted to the fixed rod, and the connector is fitted onto the fixed rod through the connecting hole.

[0008] The connector has an adjustment cavity with an upper opening located outside the connecting through hole. An insertion hole is provided in a transverse communication between the connecting through hole and the adjustment cavity. A sliding cover is slidably installed at the upper opening of the adjustment cavity. A locking block corresponding to the insertion hole is provided at the end of the sliding cover. The sliding cover drives the locking block to slide in the forward and reverse directions toward the insertion hole. The vertical rod has multiple height adjustment holes spaced apart along the height direction. The fixed rod has a fixed hole corresponding to the insertion hole. The vertical rod is inserted into the inner cavity of the fixed rod, so that one of the height adjustment holes corresponds to the fixed hole and the insertion hole. The locking block is inserted into the corresponding insertion hole, fixed hole and height adjustment hole in sequence, and is limited to the locked position under the action of the spring, so that the fixed rod is connected and fixed to the support foot.

[0009] Preferably, the spring and the limiting channel are provided in the adjustment cavity, and the spring is disposed in the limiting channel; the extension and contraction direction of the spring is parallel to the sliding direction of the sliding cover, one end of the spring is fixed to the inner wall of the adjustment cavity away from the insertion hole, and the other end contacts the locking block, thereby limiting the locking block to the locked position by the spring.

[0010] Preferably, cantilever hooks are provided on both sides of the sliding cover, and sliding grooves corresponding to the cantilever hooks are provided on both sides of the adjustment cavity. The cantilever hooks are fastened in the sliding grooves and slide along the sliding grooves to realize the sliding installation of the sliding cover on the adjustment cavity.

[0011] Preferably, a slide rail is provided in the sliding groove along the sliding direction, and the hook protruding outward from the lower end of the cantilever hook is fastened to the lower end face of the slide rail, so that the cantilever hook is limited to sliding within the corresponding sliding groove.

[0012] Preferably, when the sliding cover slides to its maximum travel in the direction of the insertion hole, the locking block is in the locked position; when the locked sliding cover slides to its maximum travel in the direction away from the locking insertion hole, the locking block is in the unlocked position, and the locking block disengages from the height adjustment hole and the fixing hole, but does not completely disengage from the insertion hole.

[0013] Preferably, the connector and the fixing rod are connected by a snap-fit ​​structure.

[0014] Preferably, an avoidance groove and a snap-fit ​​block protruding from the avoidance groove and protruding towards the connecting through hole are provided on the inner wall of the connecting through hole. The upper end of the snap-fit ​​block is connected to the upper edge of the avoidance groove, and the rest of the block is disconnected from the edge of the avoidance groove. The fixing rod is provided with a slot corresponding to the snap-fit ​​block. The connection between the connector and the fixing rod is achieved by the snap-fit ​​connection between the snap-fit ​​block and the slot.

[0015] Preferably, the connector has a horizontal insertion hole adapted to the connecting rod, and the connecting rod is inserted into the insertion hole; a ball is provided on the side wall of the connecting rod, and a drop area is provided in the insertion hole, with the ball being limited in the drop area; a hollow part communicating with the drop area is provided on the outer wall of the connector, and a pressing part is provided in the hollow part that can be pressed towards the drop area. Pressing the pressing part 443 causes the pressing part to squeeze towards the drop area, thereby squeezing the ball out of the drop area.

[0016] Preferably, an inlet portion corresponding to the insertion direction of the ball is provided at the port of the insertion hole, and the inlet portion is configured as a guide slope raised from the side wall of the port of the insertion hole.

[0017] Preferably, the support leg is L-shaped and includes a horizontally arranged pressure plate and a vertical rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model proposes a novel mosquito net easy-to-install structure with a lower fixing frame support component comprising a support foot, a fixing rod, and a connector. The fixing rod is connected to the vertical rod of the support foot. The connector has a vertically penetrating connecting hole adapted to the fixing rod, and the connector is fitted onto the lower end of the fixing rod through the connecting hole. An adjustment cavity is provided on the outside of the connecting hole of the connector, and an insertion hole is provided on the wall between the connecting hole and the adjustment cavity. A sliding cover is horizontally slidably installed on the adjustment cavity, and a locking block corresponding to the insertion hole is provided at the end of the sliding cover. The vertical rod has multiple height adjustment holes in the height direction, and the fixing rod has a fixing hole corresponding to the insertion hole. The upper end of the vertical rod is inserted into the inner cavity of the lower end of the fixing rod. By selecting a height adjustment hole corresponding to a fixing hole and an insertion hole, the locking block is sequentially inserted into the corresponding insertion hole, fixing hole, and height adjustment hole. The locking block prevents relative movement between the vertical rod and the fixing rod, thus limiting their relative positions and fixing the vertical rod and the fixing rod. By moving the sliding cover, the locking block is moved in the direction of disengaging from the insertion hole. When the locking block disengages from the height adjustment hole, the connection between the vertical rod and the fixed rod is released. The support assembly is easy to assemble, height is adjustable, and the height adjustment operation is convenient and labor-saving.

[0020] The connectors, fixing rods, and support legs are all connected by insertion, making it simple, convenient, and easy to assemble and disassemble. The insertion height of the support legs can be adjusted by pushing the sliding cover on the connector, making height adjustment of the mosquito net installation structure more convenient. The sliding cover is controlled by horizontal pushing, ensuring stable pushing direction, smoother operation, and greater durability. Attached Figure Description

[0037] Reference Figures 1 to 12 This utility model provides a novel mosquito net easy-to-install structure, including a lower fixing frame 10 arranged in a rectangle and an upper support frame 20 connected to the lower fixing frame 10, such as... Figure 2 As shown, the upper support frame 20 is composed of multiple connected rods. Figure 3 As shown, the lower fixing frame 10 includes multiple height-adjustable support components and connecting rods 2 connecting adjacent support components. The support components include support feet 3, fixing rods 1, and connectors 4. The support feet are L-shaped and include a horizontally arranged pressure plate 32 and a vertically arranged vertical rod 31. The pressure plate 32 presses the support feet under the mattress, thereby fixing them to the side of the bed.

[0038] At least one of the fixed rods 1 is hollow. The fixed rod 1 is connected to the vertical rod 31 and is vertically positioned at the four corners of the bed. Connecting rods 2 are sequentially positioned between the upper and lower ends of two adjacent fixed rods 1. Connecting pieces 4 are vertically threaded through and have connecting through holes 41 adapted to the fixed rods. Connecting pieces 4 are fitted onto the lower end of the fixed rod 1 through the connecting through holes 41. The upper end of the vertical rod 31 of the support leg 3 is inserted into the inner cavity of the lower end of the fixed rod 1.

[0039] An adjusting cavity 42 is provided on the outside of the connecting through hole 41 of the connector 4. The adjusting cavity 42 has an opening at the top, and an insertion hole 411 is provided on the side wall of the connecting through hole 41. The side wall where the insertion hole 411 is located is also the side wall of the adjusting cavity 42, and is spaced between the connecting through hole 41 and the adjusting cavity 42. The insertion hole 411 connects the connecting through hole 41 and the adjusting cavity 42. A sliding cover 43 is horizontally slidably installed at the upper opening of the adjusting cavity 42. A locking block 431 corresponding to the insertion hole 411 is provided at the end of the sliding cover 43. The locking block 431 is inserted into the insertion hole 411. The locking block 431 slides with the sliding cover 43 in the direction of insertion or disengagement from the insertion hole 411, thereby controlling the depth of insertion of the locking block 431 into the insertion hole 411. The vertical rod 31 of the support leg 3 has multiple height adjustment holes 311 in the height direction. The fixed rod 1 has a fixed hole 11 corresponding to the insertion hole 411. When a certain height adjustment hole 311 is selected to correspond to the fixed hole 11 and the insertion hole 411, the locking block 431 is inserted into the corresponding insertion hole 411, fixed hole 11 and height adjustment hole 311 in sequence. The locking block 431 prevents the relative movement of the vertical rod 31 and the fixed rod 1, so that their relative positions are limited, thereby connecting and fixing the vertical rod 31 and the fixed rod 1. By moving the sliding cover 43, the locking block 431 is moved in the direction of disengaging from the insertion hole 411. When the locking block 431 disengages from the height adjustment hole 311, the connection between the vertical rod 31 and the fixed rod 1 is released.

[0040] Cantilever hooks 432 are provided on both sides of the lower part of the sliding cover 43. Corresponding sliding grooves 423 are provided on both sides of the upper opening of the adjusting cavity 42. A slide rail 424 is provided in the sliding groove 423. The upper end face of the hook 433 protruding outward at the lower end of the cantilever hook 432 abuts against the lower end face of the slide rail 424 to fasten it to the lower end face of the slide rail 424, so that the cantilever hook is slidably connected in the sliding groove 423 and guides the cantilever hook 432 to slide along the slide rail 424. The cantilever hooks 432 on both sides are limited to sliding in the corresponding sliding grooves 423, thereby limiting the sliding range of the sliding cover 43. When the sliding cover 3 slides to its farthest stroke in the direction close to the insertion hole 411 (this position is called the locked position), the locking block 431 penetrates into the insertion hole 411, and the end of the sliding cover 3 lightly touches the outer wall surface of the connecting through hole 41, and the two match in shape. When the sliding cover 3 slides to its maximum travel distance away from the insertion hole 411 (this position is called the unlock position), the card block 431 disengages from the height adjustment hole 311 and the fixing hole 11, but does not completely disengage from the insertion hole 411. This ensures that the card block 431 is always inside the insertion hole 411, and there is no need to realign the two, making the insertion of the card block 431 smoother.

[0041] A spring 421 and a limiting channel 422 are provided inside the adjusting cavity 42. The spring 421 is located inside the limiting channel 422. One end of the spring 421 is fixed to the inner wall of the adjusting cavity 42 away from the insertion hole 411, and the other end is in contact with the locking block 431. When the sliding cover 43 slides to its farthest stroke in the direction close to the insertion hole 411, the spring 421 is in a natural state or a slightly elastic state, so that the sliding cover 43 is positioned at this position. When the sliding cover 43 is pushed in the opposite direction by an external force, so that the sliding cover 3 slides in the direction away from the insertion hole 411, the spring 421 is compressed, generating an elastic force to push the sliding cover 3 back to its original position, so that the sliding cover 3 automatically resets when the external force disappears.

[0042] To facilitate pushing the sliding cover 43, a gripping part 434 is provided on the sliding cover 43 to provide a point of leverage when pushing.

[0043] When the vertical rod 31 of the support foot is vertically connected to the fixed rod 1, the sliding cover 43 is pushed to the unlocked position. The front end of the locking block 431 retracts to the insertion hole 411 and compresses and deforms the spring 421, inserting it into the inner cavity of the fixed rod 1. The vertical rod 31 is adjusted to a suitable height, and a height adjustment hole 311 is aligned with the fixed hole 11. The sliding cover 43 is then released, and the spring 421 returns to its original shape and pushes the locking block 431 through the insertion hole 411 and the fixed hole 11 into the corresponding height adjustment hole 311, completing the connection and fixing the height. The multiple height adjustment holes 311 are used to adjust the overall height of the vertical rod 31 after it is connected to the fixed rod 1.

[0044] An inwardly protruding support portion 412 is provided around the lower inner wall of the connecting through hole 41. In this embodiment, the support portion 412 is in the form of an open annular boss that is provided around the lower end of the inner wall at the same horizontal plane. The end of the fixing rod 1 is inserted from the upper port of the connecting through hole 41 and travels to the upper end face of the support portion 412. The support portion 412 restricts the travel of the fixing rod 1.

[0045] To further secure the connection between the fixing rod 1 and the connector 4, a clearance groove and a locking block 413 protruding from the clearance groove and towards the connection through hole 41 are provided on the inner wall of the connection through hole 41. The locking block 413 is configured such that its upper end is connected to the upper edge of the clearance groove, while the rest of its parts are disconnected from the edge of the clearance groove, allowing it to be pressed into the clearance groove. Furthermore, the side of the locking block 413 facing the connection through hole 41 is a sloping surface, with the slope direction consistent with the insertion direction of the fixing rod 1, facilitating the insertion of the fixing rod 1. The fixing rod 1 is provided with a locking groove 12 corresponding to the locking block 413. When the fixing rod 1 is inserted, the snap-fit ​​block 413 is squeezed by the outer wall of the fixing rod 1 and retracts into the clearance groove until the slot 12 is aligned with the snap-fit ​​block 413. Then the squeezing force on the snap-fit ​​block 413 disappears and it springs back into the slot 12. The snap-fit ​​connection between the snap-fit ​​block 413 and the slot 12 makes the connection between the connector 4 and the fixing rod 1 more stable, thereby ensuring that the insertion hole 411 is aligned with the fixing hole 11.

[0046] The connector 4 also connects to the connecting rod 2. Each connector 2 is connected to the end of two connecting rods 2, and the connecting rods 2 are connected between two adjacent connectors 2. The connector 4 is provided with insertion holes 44 for horizontal insertion of the connecting rods 2. In this embodiment, the two insertion holes 44 provided on the connector 2 are located on the horizontal plane and are perpendicular to each other. The plane where the two insertion holes 44 are located is perpendicular to the central axis of the connecting through hole 41.

[0047] A ball bearing is provided on the side wall of the connecting rod 2. The ball bearing is in the form of a U-shaped or V-shaped spring with a ball bearing, which is commonly used in current applications. The spring is inserted into the inner cavity of the connecting rod 2, and the ball bearing on one side of the spring bearing protrudes from the through hole on the connecting rod 2. This technology is prior art and will not be described in detail here. An inlet part 441 is provided at the front end of the insertion hole 44 to facilitate the introduction of the ball bearing. In this embodiment, the inlet part 441 is set as a semi-funnel-shaped guide slope that protrudes from the front side wall of the insertion hole 44. After the ball bearing enters the inlet part 441, the entry channel is gradually narrowed, the ball bearing is gradually compressed, and finally it is completely inserted into the insertion hole 44.

[0048] In order to position the marble, a drop area 442 is provided in the insertion hole 44. In this embodiment, the drop area 442 is set as a limiting groove recessed along the inner wall of the insertion hole 44. After the marble enters the drop area 442, it is stuck, thereby achieving the function of allowing the connecting rod 2 to be inserted but not pulled out at will.

[0049] In order for the connecting rod 2 to be actively pulled out by the user, a hollow position is provided on the outer wall of the insertion hole 44 corresponding to the drop area 442, which is connected to the drop area 42. A pressing part 443 is provided in the hollow position, which can be pressed in the direction of the drop area 422. When it is necessary to pull out the connecting rod 2 from the insertion hole 44, the pressing part 443 is pressed, and the pressing part 443 is squeezed in the direction of the drop area 442, so that the ball 21 in the drop area 442 is squeezed out. At this time, the connecting rod 2 can be pulled outward by force.

[0050] This product has a simple structure, is easy to operate, and has a stable connection.
