Description

Technical Field

[0001] This utility model relates to the field of household goods technology, specifically to a lifting buckle mechanism for mosquito net brackets. Background Technology

[0002] Summer's hot and dry weather brings abundant mosquitoes, making mosquito nets an essential bedding item for avoiding mosquito bites while sleeping. They are widely favored for their environmental friendliness, breathability, and reusability. Most mosquito nets are made of mesh and require a specific support frame. However, existing mosquito net frames are mainly assembled section by section using connecting pipes. When adjusting the height of the frame, these connecting pipes must be manually disassembled or added section by section. This is not only cumbersome to place and prone to losing connecting pipes, but also tedious, time-consuming, and inefficient, thus limiting their effectiveness. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a lifting buckle mechanism for mosquito net brackets that is simple in structure, easy to lock and open, convenient to use, and easy to adjust in height.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A lifting buckle mechanism for a mosquito net frame includes a buckle body and a locking wrench. The buckle body has an outer tube cavity and an inner tube cavity that are interconnected inside. A step is formed between the outer tube cavity and the inner tube cavity. A hinge seat is provided on the side of the buckle body near the inner tube cavity. The locking wrench is hinged to the hinge seat through a hinge shaft.

[0006] The hinge seat has an elastic locking tongue formed inside, and the locking wrench has an abutment protrusion for abutting against the elastic locking tongue, so that the elastic locking tongue bends into the inner tube cavity through elastic deformation. The locking wrench can be switched between a locked state where the abutment protrusion abuts against the elastic locking tongue and an open state where the abutment protrusion does not abut against the elastic locking tongue by rotation.

[0007] As a further improvement to the above technical solution:

[0008] The inner diameter of the outer tube cavity is larger than the inner diameter of the inner tube cavity.

[0009] The elastic locking tongue has a pressing part on the side away from the outer tube cavity, and a deformation part on the side of the elastic locking tongue close to the outer tube cavity. The inner diameter of the deformation part is larger than the inner diameter of the pressing part.

[0010] The inner diameter of the deformable part is equal to the inner diameter of the outer tube cavity, and the inner diameter of the pressing part is equal to the inner diameter of the inner tube cavity.

[0011] The locking wrench has a claw portion on the side away from the hinge shaft. The claw portion has a first concave arc surface on the side near the buckle body. The buckle body has a second concave arc surface on the side opposite to the first concave arc surface. A force-applying cavity is formed between the first concave arc surface and the second concave arc surface to facilitate the insertion of a finger.

[0012] The hook portion has an outwardly convex arc surface on the side away from the buckle body.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This utility model discloses a lifting buckle mechanism for mosquito net supports, comprising a buckle body and a locking wrench. The locking wrench is hinged to a hinge seat via a hinge shaft. An elastic locking tongue is formed inside the hinge seat. During assembly, the outer tube of the support is fitted into the outer tube cavity, with the end of the outer tube abutting against the stepped portion. The inner tube of the support is fitted into the inner tube cavity. When the locking wrench is in the locked state, the abutting protrusion abuts against the elastic locking tongue, causing the elastic locking tongue to elastically deform and bend towards the inner side of the inner tube cavity. This causes the elastic locking tongue to press against the outer wall of the inner tube, preventing axial movement of the inner tube. When the locking wrench is in the open state, the abutting protrusion does not abut against the elastic locking tongue, and the elastic locking tongue returns to its original shape. The elastic locking tongue no longer presses against the outer wall of the inner tube, allowing the inner tube to move axially, thus realizing the lifting and lowering adjustment of the mosquito net support. It has the advantages of simple structure, convenient locking and opening operation, good ease of use, and easy height adjustment. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 7 As shown, the lifting buckle mechanism for a mosquito net bracket in this embodiment includes a buckle body 1 and a locking wrench 2. The buckle body 1 has an outer tube cavity 101 and an inner tube cavity 102 that are interconnected. A step portion 103 is formed between the outer tube cavity 101 and the inner tube cavity 102. A hinge seat 104 is provided on the side of the buckle body 1 near the inner tube cavity 102. The locking wrench 2 is hinged to the hinge seat 104 through a hinge shaft 3. An elastic locking tongue 105 is formed in the hinge seat 104. The locking wrench 2 has an abutment protrusion 201 for abutting against the elastic locking tongue 105, so that the elastic locking tongue 105 bends towards the inner side of the inner tube cavity 102 through elastic deformation. The locking wrench 2 can switch between a locked state where the abutment protrusion 201 abuts against the elastic locking tongue 105 and an open state where the abutment protrusion 201 does not abut against the elastic locking tongue 105 by rotation. The lifting clamp mechanism for mosquito net supports includes a clamp body 1 and a locking wrench 2. The locking wrench 2 is hinged to a hinge seat 104 via a hinge pin 3. An elastic locking tongue 105 is formed inside the hinge seat 104. During assembly, the outer tube of the support (not shown in the figure) is fitted into the outer tube cavity 101, and the end of the outer tube abuts against the stepped portion 103. The inner tube of the support (not shown in the figure) is fitted into the inner tube cavity 102. When the locking wrench 2 is in the locked state, the abutting protrusion 201 abuts against the elastic locking tongue 105, causing the elastic locking tongue 105 to... The elastic deformation occurs and it bends towards the inner tube cavity 102, thereby the elastic locking tongue 105 abuts against the outer wall of the inner tube of the bracket, preventing the inner tube of the bracket from moving axially. When the locking wrench 2 is in the open state, the abutting protrusion 201 does not abut against the elastic locking tongue 105, the elastic locking tongue 105 returns to its original shape, the elastic locking tongue 105 does not abut against the outer wall of the inner tube of the bracket, and the inner tube of the bracket can move axially, realizing the lifting and lowering adjustment of the mosquito net bracket. It has the advantages of simple structure, convenient locking and opening operation, good ease of use, and easy height adjustment.

[0026] Preferably, the inner diameter of the outer tube cavity 101 is larger than the inner diameter of the inner tube cavity 102. In this embodiment, the inner diameter of the outer tube cavity 101 is larger than the inner diameter of the inner tube cavity 102, that is, the wall thickness of the outer tube cavity 101 is thinner, and the wall thickness of the inner tube cavity 102 is thicker. The upright of the mosquito net support includes an outer support tube and an inner support tube. The inner diameter of the outer support tube is larger than the outer diameter of the inner support tube, so that the inner support tube can be inserted into the outer support tube. The outer support tube is fitted into the outer tube cavity 101, and the end of the outer support tube abuts against the stepped portion 103, so that the outer support tube and the clamp body 1 maintain a relatively fixed position. The inner tube of the support is fitted inside the inner tube cavity 102, allowing the inner tube to move axially relative to the clamp body 1. When the locking wrench 2 is in the locked state, the elastic locking tongue 105 will press against the inner tube of the support to prevent the inner tube from moving axially. When the locking wrench 2 is in the open state, the elastic locking tongue 105 returns to its original state and does not press against the inner tube of the support, allowing the inner tube of the support to extend into or out of the outer tube of the support, thereby realizing the lifting and lowering adjustment of the mosquito net support.

[0027] Preferably, the elastic locking tongue 105 has a pressing portion 1051 on the side away from the outer tube cavity 101, and a deformable portion 1052 on the side of the elastic locking tongue 105 closer to the outer tube cavity 101. The inner diameter of the deformable portion 1052 is larger than the inner diameter of the pressing portion 1051. In this embodiment, the inner diameter of the deformable portion 1052 is larger than the inner diameter of the pressing portion 1051, that is, the wall thickness of the deformable portion 1052 is thinner, and its flexibility is better, which facilitates the elastic bending deformation of the deformable portion 1052. The wall thickness of the pressing portion 1051 is thicker, so that the deformable portion 1052 only needs a small degree of bending deformation to generate a large radial locking force.

[0028] Preferably, in this embodiment, the inner diameter of the deformable part 1052 is equal to the inner diameter of the outer tube cavity 101, and the inner diameter of the pressing part 1051 is equal to the inner diameter of the inner tube cavity 102.

[0029] Preferably, the locking wrench 2 has a claw portion 202 on the side away from the hinge pin 3. The claw portion 202 has a first concave arc surface 2021 on the side near the clamp body 1, and the clamp body 1 has a second concave arc surface 106 on the side opposite to the first concave arc surface 2021. A force-applying cavity 4 is formed between the first concave arc surface 2021 and the second concave arc surface 106, facilitating finger insertion. In this embodiment, the claw portion 202 has a first concave arc surface 2021, and the clamp body 1 has a second concave arc surface 106. When the locking wrench 2 is in the locked state, a force-applying cavity 4 is formed between the first concave arc surface 2021 and the second concave arc surface 106, allowing the user to easily insert their finger into the force-applying cavity 4 to pull the locking wrench 2, resulting in good ease of use.

[0030] Preferably, the hook portion 202 has an outwardly convex arc surface 2022 on the side away from the buckle body 1. When the user pulls the locking wrench 2 outward, the outwardly convex arc surface 2022 will increase the sliding contact area between the locking wrench 2 and the mosquito net, reducing the risk of the locking wrench 2 scratching and damaging the mosquito net.

[0031] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of this utility model should also be considered within the protection scope of this utility model.
