Obviously, the drawings in the following description are only some embodiments of the present application, and other drawings can also be obtained by those skilled in the art without creative labor.

[0035] Figure 1 It is a rib mounting device with adjustable spacing.

[0036] Figure 2 It is a side view of a rib mounting device with adjustable spacing.

[0037] In the drawings, the components represented by each reference numeral are listed as follows:

[0038] 10, rib base; 20, adjusting bracket; 30, connecting arm; 31, long strip-shaped through hole; 40, positioning assembly. DETAILED DESCRIPTION

[0039] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application.

[0040] As shown in Figure 1 , Figure 2 , it is a first embodiment of a rib mounting device with adjustable spacing provided by the present application, which comprises: a rib base 10, an adjusting bracket 20, a connecting arm 30 and a positioning assembly 40; the rib base 10 is a rectangular flat plate structure, and a plurality of equidistantly distributed mounting holes are formed in the bottom; the adjusting bracket 20 is in L-shaped structure, and the long side is connected vertically to the upper surface of the rib base 10, the cross section of the long side is trapezoidal, and has an inwardly tapered inclined side wall; the connecting arm 30 is in flat long strip structure, one end of which is connected to the short side of the adjusting bracket 20 through a hinge shaft, and the other end has an arc-shaped end portion and is provided with a long strip-shaped through hole 31; the positioning assembly 40 is arranged on the adjusting bracket 20, and is used for limiting and fixing the position of the connecting arm 30.

[0041] In the above technical solution, the positioning assembly 40 includes a positioning pin and an elastic reset member; the positioning pin is vertically arranged in the side wall of the adjusting bracket 20, and the long strip-shaped through hole 31 is matched with the positioning pin to limit the moving track of the connecting arm 30 at different positions; the elastic reset member is a spring, one end of which is fixedly connected to the inner side wall of the adjusting bracket 20, and the other end is abutted against the side wall of the connecting arm 30 to provide an elastic force for restoring the position.

[0042] There is only one long strip-shaped through hole on the connecting arm, and the principle of limiting the moving track of the connecting arm by cooperating with the positioning pin is not complex. The positioning pin is vertically arranged in the side wall of the adjusting bracket, and the length direction of the long strip-shaped through hole extends along the length direction of the connecting arm. When the connecting arm rotates relative to the adjusting bracket around the hinge shaft, the positioning pin can be inserted at different positions of the long strip-shaped through hole. For example, when the connecting arm is rotated to a certain angle, the positioning pin can be inserted into the position of the long strip-shaped through hole close to the arc-shaped end, at which time the connecting arm is fixed at the angle; if it is necessary to change the angle of the connecting arm, the positioning pin is pulled out, the connecting arm is rotated to a new angle, and then the positioning pin is inserted into the new position of the long strip-shaped through hole.

[0043] When the elastic reset member is installed, one end thereof is fixed to the position close to the hinge shaft on the inner side wall of the short side of the adjusting bracket, and then extends obliquely to the direction of the connecting arm at a certain angle, so that when the connecting arm rotates around the hinge shaft, the side wall thereof will be in contact with and abut against the free end of the elastic reset member. For example, when the connecting arm rotates outward, the elastic reset member will be squeezed to contract, and when the connecting arm rotates back, the elastic reset member will be in contact with the side wall of the connecting arm by virtue of the elastic force, so as to restore the position. The elastic reset member extending obliquely to the direction of the connecting arm at a certain angle refers to extending to the direction of the connecting arm inside the adjusting bracket. The inner side wall of the short side of the adjusting bracket is the installation position of the fixed end of the elastic reset member, and the elastic reset member extends in the adjusting bracket at an oblique angle towards the direction of the connecting arm. Thus, when the connecting arm rotates, it can be in contact with the elastic reset member inside the adjusting bracket and interact with each other.

[0044] Further, in the above technical solution, the outer edge of the arc-shaped end of the connecting arm 30 is provided with anti-skid texture, and a plurality of limiting grooves distributed in concentric circles are formed on the surface thereof; the diameter of the positioning pin is matched with the depth of the limiting groove.

[0045] The diameter of the positioning pin and the depth of the limiting groove maintain a certain proportional relationship in design, and usually the diameter of the positioning pin is slightly smaller than the depth of the limiting groove (for example, the diameter of the positioning pin is 2 mm, and the depth of the limiting groove is 2.2 mm), so as to ensure that the positioning pin can be smoothly inserted into the limiting groove, and a stable limiting effect is formed after being inserted.

[0046] Further, in the above technical solution, the trapezoidal sidewall of the adjusting bracket 20 is internally provided with a plurality of reinforcing ribs arranged in the height direction, the reinforcing ribs are in a triangular wedge structure, and the reinforcing ribs are used to enhance the structural strength of the adjusting bracket 20.

[0047] Further, in the above technical solution, the mounting hole of the rib base 10 is a tapered hole, and the hole wall of the tapered hole has a chamfer, which is used to facilitate the installation and positioning of the fastener.

[0048] The chamfer width refers to the horizontal projection length of the chamfer at the edge of the hole. For the chamfer of the tapered hole, the width is usually between 0.1 mm and 0.5 mm. This range can not only ensure that the fastener (such as a screw or a bolt) is smoothly introduced during installation, but also will not weaken the structural strength of the mounting hole due to the chamfer being too large.

[0049] The chamfer angle refers to the included angle between the chamfer slope and the hole wall. The chamfer angle is designed to be 30° to 45°.

[0050] Further, in the above technical solution, the inner wall of the long strip-shaped through hole 31 of the connecting arm 30 is provided with a wear-resistant rubber bushing, which is used to reduce the friction between the positioning pin and the long strip-shaped through hole 31 and improve the positioning accuracy.

[0051] Further, in the above technical solution, the surface of the rib base 10 presents a micro-wavy anti-slip texture.

[0052] Further, in the above technical solution, the material of the connecting arm 30 is aluminum alloy.

[0053] Further, in the above technical solution, the number of positioning pins and elastic return members is 2, and they are symmetrically arranged.

[0054] The two positioning pins are symmetrically distributed about the center axis (or the symmetry plane) of the connection position of the adjusting bracket and the connecting arm. That is, if the connection point of the connecting arm and the short side of the adjusting bracket is taken as the center, the two positioning pins are respectively located on both sides of the center, the distance to the center in the horizontal direction (or the direction related to the connection of the connecting arm and the adjusting bracket) is equal, and in the direction perpendicular to the center axis (or the symmetry plane), the two positioning pins are at the same height position.

[0055] Similarly, the two elastic return members are also symmetrically distributed about the center axis (or the symmetry plane) of the connecting position of the adjusting bracket and the connecting arm. On the inner side wall of the adjusting bracket, the two elastic return members are respectively located on both sides of the center axis (or the symmetry plane), and the distances to the center in the horizontal direction (or the direction related to the connection between the connecting arm and the adjusting bracket) are equal, and in the vertical direction, the installation heights of the two elastic return members are also the same. When the connecting arm moves relative to the adjusting bracket, the two symmetrically arranged elastic return members can provide uniform elastic force, ensuring the stability and balance of the connecting arm during movement and positioning, and the two symmetrically arranged positioning pins can more stably limit and position different positions of the connecting arm.

[0056] Further, in the above technical solution, the surface of the adjusting bracket 20 is provided with an anti-corrosion treatment.

[0057] The anti-corrosion treatment can include the following ways:

[0058] Electroplating treatment: electroplating a layer of corrosion-resistant metal (such as zinc, nickel, chromium, etc.) on the surface of the adjusting bracket to form a dense protective layer to isolate external corrosive media.

[0059] Spraying treatment: spraying a layer of anti-corrosion paint (such as epoxy resin, polyurethane, etc.) on the surface of the adjusting bracket to form a uniform protective film to enhance the corrosion resistance.

[0060] Anodic oxidation treatment: For the adjusting bracket made of aluminum alloy, an anodic oxidation process is used to form an aluminum oxide protective film on its surface to improve corrosion resistance and wear resistance.

[0061] Chemical passivation treatment: A dense passivation film (such as passivation treatment of stainless steel) is formed on the surface of the adjusting bracket by chemical methods to prevent corrosion of corrosive media.

[0062] Nano coating treatment: Using nanotechnology, a super-thin and dense nano coating is formed on the surface of the adjusting bracket, which has the functions of anti-corrosion, wear resistance and self-cleaning.

[0063] Specifically, the principle of the present application is:

[0064] The porous design of the rib base:

[0065] The rib base serves as the installation foundation of the entire device, and its design directly affects the application range and practicality of the device. Traditional rib installation devices usually adopt a fixed design, which is difficult to adapt to the individual needs of different human body shapes and use scenarios. The utility model provides a flexible spatial layout basis for the device through the multi-hole design. Specifically, a plurality of installation holes are uniformly distributed on the rib base, which can be selected and used according to actual needs, so as to realize flexible installation of the device at different positions and angles. The multi-hole design also enables the device to adapt to different use scenarios. This multi-hole design not only significantly improves the application range and practicality of the device, but also provides a solid foundation for precise adjustment of the device;

[0066] The trapezoidal structure of the L-shaped adjustment bracket:

[0067] The L-shaped adjustment bracket is an important component connecting the rib base and the connecting arm, and its design directly affects the adjustment accuracy and flexibility of the device. Traditional adjustment brackets usually adopt a simple straight line or right angle design, which is difficult to achieve precise position adjustment. The utility model provides a flexible spatial layout basis for the device through the design of the trapezoidal structure. Specifically, the trapezoidal structure of the L-shaped adjustment bracket enables the position and angle of the bracket in space to be flexibly adjusted, thereby realizing precise adjustment of the device. In addition, the trapezoidal structure also makes the adjustment bracket more stable when stressed, avoiding device loosening or displacement caused by uneven stress. This design not only significantly improves the adjustment accuracy and flexibility of the device, but also provides an important guarantee for the use stability of the device;

[0068] The arc-shaped end of the connecting arm and the long strip-shaped through hole:

[0069] The connecting arm is an important component connecting the adjustment bracket and the positioning component, and its design directly affects the positioning accuracy and adjustment flexibility of the device. Traditional connecting arms usually adopt a straight line design, which is difficult to achieve precise position adjustment. The utility model provides a flexible adjustment basis for the device through the design of the arc-shaped end and the long strip-shaped through hole. Specifically, the arc-shaped end of the connecting arm enables the device to realize smooth rotation and positioning during adjustment, thereby improving the adjustment accuracy of the device. The design of the long strip-shaped through hole enables the position of the connecting arm to be flexibly adjusted, thereby realizing precise positioning of the device. This design not only significantly improves the positioning accuracy and adjustment flexibility of the device, but also provides an important guarantee for the use convenience of the device;

[0070] Elastic return element:

[0071] The elastic reset piece as an important component of the connecting arm directly affects the convenience and stability of the device. The traditional rib mounting device usually lacks automatic reset function, which leads to loosening or displacement of the device during use. The utility model discloses the design of elastic reset piece, so that the connecting arm can automatically return to the initial state after adjustment, thereby greatly improving the convenience and stability of the device. Specifically, the elastic reset piece is made of high-elasticity material, which can automatically recover to the original state after the adjustment of the connecting arm, thereby avoiding loosening or displacement of the device caused by long-term use. In addition, the design of the elastic reset piece also makes the adjustment process smoother, avoiding the inconvenience caused by difficult adjustment. This design not only significantly improves the convenience and stability of the device, but also provides an important guarantee for long-term use of the device.
