Description

Technical Field

[0001] The utility model belongs to the technical field of springs, and in particular relates to a braces auxiliary spring. Background Art

[0002] Braces auxiliary springs usually need to withstand large and long-term stress during use. Existing braces auxiliary springs are prone to becoming unstable in the fixed connection with the braces after long-term use, and are prone to loosening and displacement during use, affecting the use effect, shortening the product life, and increasing the cost of use. Utility Model Content

[0003] The purpose of the present utility model is to provide a braces auxiliary spring to solve the technical problem that the existing braces auxiliary spring has poor stability in the fixed connection with the braces after long-term use.

[0004] The utility model is realized through the following technical solutions: a braces auxiliary spring, comprising an arc-shaped elastic rod and a fixing part connected to both ends of the arc-shaped elastic rod, the fixing part is located on the circular inward side corresponding to the arc-shaped elastic rod, the arc-shaped elastic rod and the two fixing parts are semi-enclosed and fixedly installed on the side of the braces, the fixing part comprises a fixing ring, an insertion pin and a connecting rod, the fixing ring is fixedly connected to the insertion pin through the connecting rod, the connecting rod is close to the outer surface of the side of the braces, the fixing directions of the fixing rings on the two fixing parts are on the same straight line, the fixing directions of the insertion pins on the two fixing rings are also on the same straight line, and the fixing directions of the fixing ring and the insertion pin on the braces are parallel to each other.

[0005] Furthermore, the arc-shaped elastic rod is connected to the fixing portion via an arc-shaped transition rod, and the circular diameter corresponding to the arc-shaped transition rod is smaller than the circular diameter corresponding to the arc-shaped elastic rod.

[0006] Furthermore, the arc-shaped elastic rod, the arc-shaped transition rod and the insertion pin are located on the same plane, and the fixing ring is perpendicular to the plane.

[0007] Furthermore, the fixing ring is a spiral ring body, and both ends of the fixing ring are respectively connected to the arc-shaped transition rod and the connecting rod, and the connecting line between the arc-shaped transition rod and the connecting rod passes through the corresponding center point of the fixing ring.

[0008] Furthermore, the connecting rod and the pin are arranged perpendicular to each other.

[0009] Furthermore, the arc-shaped elastic rod and the fixing portion are integrally formed by bending metal wire.

[0010] When the present invention is fixedly installed on the side of the braces, the fixing parts are symmetrically fixed at the positions on both sides of the braces, so that the stress generated when the fixed elastic rod is deformed by force can be evenly distributed to the fixing parts at both ends thereof, avoiding excessive force on the unilateral fixing part causing easy loosening, thereby enhancing the overall stability of the product during use; by arranging the fixing ring and the insertion pin, the fixing part has two ways of being fixed on the side of the braces. Under long-term use of the product, even if one of the fixing methods is slightly loosened, the other fixing method will maintain a relatively stable state through the traction of the connecting rod, thereby ensuring the stability of the spring fixed on the braces and extending the service life of the product.

[0015] The present invention will be further described below with reference to specific examples and accompanying drawings.

[0016] like Figure 1-Figure 2 As shown, the utility model describes a braces auxiliary spring, comprising an arc-shaped elastic rod 1 and a fixing portion 2 connected to both ends of the arc-shaped elastic rod 1, the fixing portion 2 is located on the circular inward side corresponding to the arc-shaped elastic rod 1, the arc-shaped elastic rod 1 and the two fixing portions 2 are semi-enclosed and fixedly installed on the side of the braces, the fixing portion 2 comprises a fixing ring 21, an insertion pin 22 and a connecting rod 23, the fixing ring 21 is fixedly connected to the insertion pin 22 through the connecting rod 23, the connecting rod 23 is close to the outer surface of the side of the braces, the fixing directions of the two fixing rings 21 on the fixing portions 2 are on the same straight line, the fixing directions of the two insertion pins 22 on the fixing rings 21 are also on the same straight line, and the fixing directions of the fixing ring 21 and the insertion pin 22 on the braces are parallel to each other.

[0017] When the present invention is fixedly installed on the side of the braces, the fixing parts 2 are symmetrically fixedly installed on both sides of the braces, so that the stress generated when the fixed elastic rod is deformed by force can be evenly distributed to the fixing parts 2 at both ends thereof, avoiding excessive force on one side of the fixing part 2 and causing it to become loose, thereby enhancing the overall stability of the product during use; by arranging the fixing ring 21 and the insertion pin 22, the fixing part 2 has two ways of being fixed on the side of the braces. Under long-term use of the product, even if one of the fixing methods is slightly loosened, the other fixing method will maintain a relatively stable state through the involvement of the connecting rod 23, thereby ensuring the stability of the spring fixed on the braces and extending the service life of the product.

[0018] The arc-shaped elastic rod 1 and the fixing part 2 in the present invention are connected by an arc-shaped transition rod 3. The circular diameter corresponding to the arc-shaped transition rod 3 is smaller than the circular diameter corresponding to the arc-shaped elastic rod 1, that is, the bending curvature of the arc-shaped elastic rod 1 is smaller, while the bending curvature of the arc-shaped transition rod 3 is larger. The arc-shaped transition rod 3 connects the bending transition of the arc-shaped elastic rod 1 to the fixing part 2. Since the arc-shaped elastic rod 1 is located above the braces and the fixing part 2 is located on both sides of the braces, the fixing part 2 and the arc-shaped elastic rod 1 are almost in a relatively vertical position. The arc-shaped transition rod 3 with a large bending curvature plays a good connecting and transitioning role between the two. When the arc-shaped elastic rod 1 is deformed by force, the generated stress is first transferred to the arc-shaped transition rod 3. Since the arc-shaped transition rod 3 has a large bending curvature, it is not easy to deform itself, thereby having a good stress dispersion effect, thereby avoiding the deformation of the arc-shaped transition rod 3 affecting the installation stability of the fixing part 2.

[0019] The arc-shaped elastic rod 1, the arc-shaped transition rod 3 and the insertion pin 22 in the embodiment of the present invention are located on the same plane, and the fixing ring 21 is perpendicular to the plane. The fixing ring 21 needs to be sleeved and fixed on the raised part of the side of the braces, and the insertion pin 22 only needs to be inserted into the through hole on the side of the braces. By arranging the arc-shaped elastic rod 1, the arc-shaped transition rod 3 and the insertion pin 22 to be located on the same plane, the force transmission direction can be made more stable and predictable, and the alignment installation of the insertion pin 22 is facilitated. By arranging the fixing ring 21 perpendicular to the plane, the spring as a whole can be prevented from being displaced in the vertical direction, thereby forming an effective fixation. Combined with the fixation of the insertion pin 22 in the plane, double protection is provided.

[0020] The fixing ring 21 in the embodiment of the present invention is a spiral ring body, and the two ends of the fixing ring 21 are respectively connected to the arc-shaped transition rod 3 and the connecting rod 23. The connecting line between the arc-shaped transition rod 3 and the connecting rod 23 passes through the corresponding center point of the fixing ring 21. That is to say, the arc-shaped transition ring and the connecting rod 23 are located on the same plane. The spiral ring body setting of the fixing ring 21 provides a prerequisite for the integrated molding production of the fixing ring 21, the arc-shaped transition rod 3, and the connecting rod 23. This can be achieved by bending the wire, which is conducive to simplifying production and improving production efficiency.

[0021] In the embodiment of the present invention, the connecting rod 23 and the pin 22 are perpendicular to each other. Since the pin 22 and the fixing ring 21 are installed and fixed in the same direction, the movement direction when loosening is also the same. By setting the connecting rod 23 perpendicular to the pin 22, the influence of the fixing ring 21 and the pin 22 on each other when loosening is reduced. For example, when the fixing ring 21 moves outward, the connecting rod 23 bends and deforms, and the pulling force on the pin 22 is almost perpendicular to the installation direction of the pin 22. The stress conversion result is the bending of the connecting rod 23, which avoids affecting the installation stability of the pin 22.

[0022] The arc-shaped elastic rod 1 and the fixing part 2 in the embodiment of the present invention are integrally formed by bending metal wire. The surface of the connection is smooth and there are no welding points. It is comfortable to use, and the overall structural strength is high. It can withstand greater stress without being easily broken. The production process is simple, which improves production efficiency and reduces production costs.

[0023] The above embodiments are only preferred implementation methods of the present invention and are only used to explain the present invention rather than to limit the present invention. Any changes, replacements, combinations, simplifications, modifications, etc. made by those skilled in the art without departing from the spirit and principles of the present invention shall be considered as equivalent replacement methods and shall be included in the scope of protection of the present invention.
