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 changing outdoor environment necessitates stepless adjustment mechanisms for more flexible height adjustment, a goal pursued by those skilled in the art is to develop a user-friendly and simple stepless pole height adjustment system. 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 stepless adjustment structure for rods.

[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] A fixing base, wherein the fixing base is provided with a cavity for accommodating the rod;

[0008] A stopper is fixedly connected to the fixed base, and the stopper has a stopper surface that frictionally engages with the rod.

[0009] An operating component, which is rotatably connected to the fixed base about an axis, and the operating component has an eccentric wheel that abuts against the abutting component;

[0010] The stepless adjustment structure of the rod has a locked state and an unlocked state. When it is in the locked state, the protrusion in the eccentric wheel abuts against the abutment, so that the abutment and the rod make frictional contact. When it is in the unlocked state, the protrusion in the eccentric wheel disengages from the abutment, and the abutment disengages from the rod due to its own elastic force.

[0011] In one embodiment, the side wall of the fixing seat is provided with an opening, the opening is configured to communicate with the cavity, and the abutment is disposed in the opening.

[0012] In one embodiment, the upper and lower parts of the abutment are fixedly connected to the opening, and the left and right parts of the abutment are detached from the fixing seat.

[0013] In one embodiment, the left and right sides of the abutment are fixedly connected to the opening, and the upper and lower parts of the abutment are detached from the fixing seat.

[0014] In one embodiment, the abutment is integrally formed with the fixing base.

[0015] In one embodiment, the abutting surface extends vertically in the up-down direction.

[0016] In one embodiment, the axis extends vertically in the up-down direction.

[0017] In one embodiment, the abutment has an arcuate surface that abuts against the eccentric wheel.

[0018] In one embodiment, it further includes a mating rod, which is fixedly connected to the fixing seat.

[0019] In one embodiment, it further includes a mating rod, and the fixing seat is part of the mating rod.

[0020] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0021] The stepless adjustment structure of the rod of this utility model utilizes an eccentric wheel to make the abutment and the rod in frictional contact, thereby achieving relative locking between the fixed seat and the rod. The elastic force of the abutment itself is used to achieve relative unlocking between the fixed seat and the rod, thus 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

[0029] 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.

[0030] 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 stopper 3, and an operating component 4.

[0031] 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.

[0032] The fixing seat 2 is provided with a cavity 21 for accommodating the rod 1. The cavity 21 is arranged through in the vertical direction. The side wall of the fixing seat 2 is provided with an opening 22, which is arranged through the cavity 21.

[0033] The abutment 3 is disposed in the opening 22. Specifically, the abutment 3 is integrally formed with the fixing base 2. Of course, in other embodiments, the abutment 3 can also be fixedly disposed in the opening 22, such as... Figure 4-5 As shown, the left and right sides of the abutment 3 are fixedly connected to the opening 22, and the upper and lower parts of the abutment 3 are detached from the fixing seat 2. In other embodiments, the upper and lower parts of the abutment 3 can also be fixedly connected to the opening 22, and the left and right sides of the abutment 3 can be detached from the fixing seat 2. With this arrangement, the abutment 3 can be displaced horizontally relative to the fixing seat 2 to cooperate with the rod 1. The abutment 3 has an abutment surface 31 that frictionally engages with the rod 1, and the abutment surface 31 extends vertically in the up-down direction. The abutment 3 is made of an elastic material.

[0034] The operating component 4 is used to cooperate with the abutment component 3 so that the abutment surface 31 of the abutment component 3 can approach the rod 1 and engage with the rod 1 through friction. Specifically, the operating component 4 includes an operating part 41 for user operation and a mating part 42 for cooperating with the abutment component 3. The operating part 41 and the mating part 42 are fixedly connected. The mating part 42 is rotatably connected to the fixed seat 2 about the axis X extending in the vertical direction. Specifically, the mating part 42 has a rotating shaft hole 421. The opening 22 of the fixed seat 2 has rotating shaft seats 23 on the upper and lower sides. The mating part 42 is disposed in the rotating shaft seats 23. The two are rotatably connected by a pin 5. The mating part 42 is specifically an eccentric wheel. The abutment component 3 also has an arc-shaped surface 32 that mates with the eccentric wheel.

[0035] The stepless adjustment structure of the lever has a locked state and an unlocked state, such as Figure 4 As shown, when in the locked state, the protrusion in the eccentric wheel abuts against the arc-shaped surface 32 of the abutment 3, and the elastic force of the abutment 3 itself causes the abutment surface 31 of the abutment 3 to rub against the rod 1, as shown. Figure 5 As shown, when in the unlocked state, the protrusion in the eccentric wheel disengages from the arc-shaped surface 32 of the abutment 3, and the abutment surface 31 of the abutment 3 disengages from the rod 1 due to the elastic force of the abutment 3 itself. When switching between the locked and unlocked states, the user only needs to rotate the operating component to make it rotate around the axis X, thereby causing the protrusion in the eccentric wheel to abut against or disengage from the abutment 3.

[0036] In the description of this utility model, the directions such as "front," "back," "left," "right," "up," and "down" are defined with reference to the directions observed by the user when using the stepless adjustment structure of the lever, that is, as shown below. Figure 3 As shown in the figure, the left direction is "left", the right direction is "right", the upper direction is "up", and the lower direction is "down". Directions perpendicular to the viewpoint are "forward" and "backward". These definitions are merely for ease of description and simplification, and do not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. In the description of this invention, "rotational connection" refers to a pivot connection.

[0037] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
