Description

Technical Field

[0001] This utility model relates to a rod adjustment structure, specifically a rod stepless adjustment structure. Background Technology

[0002] Pole members are a common structural element used for support and fixation. Due to varying usage environments, their height often needs adjustment. Existing pole height adjustment methods include adjustable levels and stepless adjustment. Especially for outdoor tents, where the environment is highly variable, stepless adjustment structures are often necessary for more flexible height adjustment. Therefore, developing a user-friendly and simple stepless pole height adjustment structure is a goal pursued by those skilled in the art. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a novel rod-type stepless adjustment structure.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A stepless adjustment structure for a rod includes:

[0006] rods;

[0007] The fixing seat is provided with a first cavity for accommodating the rod;

[0008] The slider, the fixed base is provided with a second cavity for accommodating the slider, the first cavity and the second cavity are connected through each other;

[0009] An operating component is rotatably connected to the fixed base about a first axis and rotatably connected to the slider about a second axis.

[0010] The stepless adjustment structure of the rod has a locked state and an unlocked state. When it is in the locked state, the slider and the rod are in frictional contact. When it is in the unlocked state, the slider and the rod are disengaged. When the operation changes from the locked state to the unlocked state, the operating member rotates around the first axis, thereby driving the slider to move away from the rod from the inside to the outside.

[0011] In one embodiment, the first axis and the second axis are arranged parallel to each other, and both extend in the horizontal direction.

[0012] In one embodiment, when transitioning from the locked state to the unlocked state, the slider is configured to move from top to bottom relative to the fixed base.

[0013] In one embodiment, the first axis line is located above the second axis line, and the first axis line is located outside the second axis line.

[0014] In one embodiment, when transitioning from the locked state to the unlocked state, the slider is configured to move from bottom to top relative to the fixed base.

[0015] In one embodiment, the first axis line is located below the second axis line and outside the second axis line.

[0016] In one embodiment, the fixing seat has a guide wall that extends obliquely from the inside to the outside, the guide wall forming part of the second cavity, and the slider has a mating surface that mates with the guide wall.

[0017] In one embodiment, the guide wall extends downwardly from the inside out, and the second cavity is formed by the left side wall, the right side wall and the guide wall, with an opening at the bottom of the second cavity.

[0018] In one embodiment, the slider has an abutting surface extending in a vertical direction and a mating surface extending downward from the inside out, the abutting surface being used for frictional abutment with the rod.

[0019] In one embodiment, the stepless adjustment structure of the lever further includes an elastic element disposed between the fixed base and the operating member, for providing the elastic force required for the operating member to rotate about the first axis, thereby causing the stepless adjustment structure of the lever to change from the unlocked state to the locked state.

[0020] In one embodiment, it further includes a mating rod, which is fixedly connected to the fixing seat, or the fixing seat is part of the mating rod.

[0021] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0022] The stepless adjustment structure of the rod of this utility model, by connecting the first cavity and the second cavity, allows the slider to cooperate with the rod and abut against it. The slider is driven by the rotational connection between the operating member and the fixed seat, and the rotational connection between the operating member and the slider, thereby realizing stepless adjustment. Therefore, the stepless adjustment structure of the rod of this utility model is simple, ingeniously designed, and has good application prospects. Attached Figure Description

Detailed Implementation

[0031] 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. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] See Figure 1-5 As shown, the stepless adjustment structure of the rod of this utility model includes a rod 1, a fixed base 2, a slider 3, an operating component 4, and an elastic component 5.

[0033] The rod 1 extends in the vertical direction. In one embodiment, the cross-section of the rod 1 is square. In other embodiments, the cross-section of the rod 1 can be circular. The stepless adjustment structure of the rod can also include a mating rod (not shown in the figure). The mating rod is fixedly connected to the fixed seat 2. Alternatively, the fixed seat 2 is part of the mating rod. By adjusting the vertical position of the rod 1 relative to the fixed seat 2, the vertical position of the mating rod relative to the rod 1 can be adjusted to achieve height adjustment.

[0034] The fixing seat 2 is provided with a first cavity 21 for accommodating the rod 1 and a second cavity 22 for accommodating the slider 3. The first cavity 21 and the second cavity 22 are connected through each other. The second cavity 22 is located outside the first cavity 21. In some embodiments, the fixing seat 2 includes a left side wall 23, a right side wall, a front side wall and a guide wall 24. The left side wall 23, the right side wall and the front side wall all extend in the vertical direction. The guide wall 24 extends downward from the inside to the outside. The left side wall 23, the right side wall and the front side wall surround to form the first cavity 21. The left side wall 23, the right side wall and the guide wall 24 surround to form the second cavity 22. The first cavity 21 has a vertically connected opening. The opening of the second cavity 22 is downward.

[0035] like Figure 4-5 As shown, the slider 3 has a triangular cross-section. The slider 3 has a vertically extending abutting surface 31 and a mating surface 32 extending downward from the inside to the outside. The abutting surface 31 is used to rub against the rod 1, and the mating surface 32 is used to mate with the guide wall 24. Specifically, the mating surface 32 and the guide wall 24 are arranged in parallel. The part of the slider 3 that mates with the guide wall 24 can have multiple slots 33 to reduce the friction between the slider 3 and the guide wall 24.

[0036] The operating component 4 is L-shaped and includes an operating part 41 extending in the vertical direction and a connecting part 42 extending in the front-back direction. The connecting part 42 is rotatably connected to the fixed base around the first axis X and rotatably connected to the slider 3 around the second axis Y. The first axis X and the second axis Y are parallel and both extend horizontally. The first axis X is located above the second axis Y and outside the second axis Y. Specifically, pins 6 can be provided to make the connecting part 42 rotatably connected to the fixed base 2 around the first axis X and to make the connecting part 42 rotatably connected to the slider 3 around the second axis Y.

[0037] The stepless adjustment structure of the lever has a locked state and an unlocked state, such as... Figure 4As shown, when in the locked state, the abutting surface 31 of the slider 3 rubs against the rod 1, and the mating surface 32 of the slider 3 abuts against the guide wall 24. The slider 3 is located above the second cavity 22. At this time, the fixed seat 2 and the rod 1 are relatively fixed and cannot slide up and down relative to each other. When switching from the locked state to the unlocked state, the user presses the operating part 42 of the operating member 4 from the outside to the inside, causing the operating member 41 to rotate counterclockwise around the first axis X, thereby causing the connecting part 42 to move downward. Since the connecting part 42 is also rotatably connected to the slider 3 around the second axis Y, the connecting part 42 also rotates counterclockwise around the second axis Y. Due to the action of the guide wall 24, the connecting part 42 drives the slider 3 from the inside to the outside and away from the rod 1, and moves from top to bottom relative to the fixed seat 2, causing part of the slider 3 to leave the second cavity 22 from the opening below the second cavity 22. Figure 5 As shown, when in the unlocked state, the abutting surface 31 of the slider 3 is disengaged from the rod 1, the mating surface 32 of the slider 3 abuts against the guide wall 24, and the slider 3 is located below the second cavity 22.

[0038] The elastic element 5 is disposed between the fixed base 2 and the operating element 4, and is used to provide the elastic force required for the operating element 4 to rotate around the first axis X, thereby causing the stepless adjustment structure of the rod to change from the unlocked state to the locked state. In one embodiment, the elastic element 5 is specifically a compression spring, one end of which abuts against the fixed base 2 and the other end of which abuts against the operating element 4. The fixed base 2 may also be provided with a limiting part 25 that cooperates with the end of the compression spring. Thus, when changing from the unlocked state to the locked state, the user only needs to stop pressing the operating part 42 of the operating element 4, and the elastic force of the elastic element 5 will drive the operating element 4 to rotate clockwise around the first axis X, thereby causing the connecting part 42 to move upward. Since the connecting part 42 is also rotatably connected to the slider 3 around the second axis Y, the connecting part 42 also rotates clockwise around the second axis Y. Due to the action of the guide wall 24, the connecting part 42 drives the slider 3 from the outside to the inside and close to the rod 1, and moves from the bottom to the top relative to the fixed base 2, so that part of the slider 3 enters the second cavity 22 from the opening below the second cavity 22.

[0039] like Figure 6 As shown, in some other embodiments, the fixed seat 2 can be configured as a guide wall 24 extending obliquely upward from the inside out, and the slider 3 can be configured as having a mating surface 32 extending upward from the inside out. The first axis X is located below the second axis Y, and the first axis X is located outside the second axis Y. When the state changes from locked to unlocked, the slider 3 is configured to move relative to the fixed seat 2 from bottom to top.
