CN 107021157 a discloses a bicycle backpack bracket, which bears most of the backpack weight, but when riding on uneven road surface, the up-and-down shaking of the bicycle brings up the up-and-down vibration of the backpack, causing the force of the shoulders of the rider to increase suddenly, which is likely to cause the rider to malfunction, resulting in a fall accident. In addition, most of the existing bicycles are not provided with a backrest, and when the bicycles are ridden for a long time, the bicycles can cause over fatigue and cause discomfort to the body.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a damping type bicycle backpack bracket, which is arranged on a saddle pipe under a bicycle seat, is suitable for riding on uneven road surfaces, reduces the body backpack bearing when a rider rides, and buffers the influence of vibration caused by roadblocks on the force control of the shoulders of the rider; meanwhile, the bicycle has the function of a backrest, and the fatigue of riding of a rider is relieved.
In order to achieve the purpose, the utility model discloses a following technical scheme, a damping formula bicycle knapsack bracket, including U type hoop, two spinal branch vaulting poles and overlap spring, backplate, the connecting plate at both ends about the bracing piece respectively, all have a reducing step and external screw thread about the bracing piece, the middle and upper position is equipped with the layer board perpendicularly in the backplate outside, and the layer board has two springs to protect a section of thick bamboo, the connecting plate both ends are crooked to become cylindrical hole, and the middle part is fixed on bicycle saddle pipe through U type hoop.
The back plate is provided with an arc-shaped back curved surface.
The back plate is sleeved on the cylindrical surface of the upper part of the supporting rod through a spring protecting cylinder, and a spring is sleeved on the upper part of the supporting rod in the spring protecting cylinder.
The supporting plate on the back plate is provided with a hole which can just pass through the threaded column at the upper end of the supporting rod.
The middle part of the connecting plate is provided with an arc surface corresponding to the excircle of the bicycle saddle tube.
The end parts of the U-shaped hoops penetrate through holes in the two sides of the middle of the connecting plate and are fastened by nuts.
The upper end of the supporting rod penetrates through a hole in the supporting plate and is provided with a flat nut and a spherical nut.
The lower section of the supporting rod penetrates through the cylindrical hole of the connecting plate and is fastened by a gasket and a nut.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. the carrying weight of the backpack falling on the upper body is reduced;
2. buffering the vibration load generated by riding over obstacles;
3. the backrest is arranged in a cambered surface mode, so that fatigue in riding is relieved.

Detailed Description
The following detailed description and technical contents of the present invention are described with reference to the accompanying drawings, which are provided for reference and illustration purposes only, and are not intended to limit the present invention.
According to the figures 1-2, the vibration damping type bicycle backpack bracket comprises a U-shaped hoop 2, two support rods 6, a spring 5, a back plate 3 and a connecting plate 7, wherein the spring 5, the back plate 3 and the connecting plate 7 are respectively sleeved at the upper end and the lower end of each support rod 6, according to the figure 4, the upper end and the lower end of each support rod 6 are respectively provided with a reducing step 602 and 603 and an external thread 601 and 604, according to the figures 5-7, the middle upper part in the outer part of the back plate 3 is vertically provided with a supporting plate 301, two spring protection cylinders 302 are arranged below the supporting plate 301, according to the figure 3, the two ends of the connecting plate 7 are bent into cylindrical.
According to the figures 1-2, the back plate 3 is sleeved on the upper cylindrical surface of the support rod 6 through a spring protection cylinder 302, and the upper part of the support rod 6 in the spring protection cylinder 302 is sleeved with a spring 5.
According to fig. 7, the back plate 3 is provided with an arc-shaped back rest curve 305. The supporting plate 301 on the back plate 3 is provided with a hole 303 which just can pass through the threaded column 601 at the upper end of the supporting rod 6.
According to fig. 3, the middle part of the connecting plate 7 is provided with an arc surface 702 corresponding to the outer circle of the bicycle saddle tube 1. The end part of the U-shaped hoop 2 passes through holes at two sides of the middle part of the connecting plate 7 and is fastened by a connecting nut 9.
According to fig. 1-2, the upper end of the support rod 6 passes through the hole 303 of the support plate 301, and the flat nut 4 and the spherical nut 401 are installed. The lower section of the support rod 6 passes through the cylindrical hole 701 of the connecting plate 7 and is fastened by a washer 801 and a fastening nut 8.
In field implementation, firstly two support rods 6 are inserted into the cylindrical holes 701 of the connecting plate 7, a washer 801 and a fastening nut 8 are installed, then two springs 5 are respectively sleeved on the upper parts of the support rods 6, the holes 303 on the supporting plate 301 of the back plate 3 are inserted in alignment with the threaded columns at the upper ends of the support rods 6, and a flat nut 4 and a spherical nut 401 are respectively installed. Finally, the mounted device is mounted on a saddle tube 1 under the saddle of the bicycle through a U-shaped hoop 2.
When a rider rides the backpack, the bottom of the backpack is placed on the supporting plate 301 of the back plate 3 after the backpack is backed, so that the load and the vibration load of the rider are reduced; the back of the rider can abut against the cambered surface 305 of the back plate 3 for a short time to rest; the backpack is slightly isolated from the back of the rider through the back plate 3, so that sweat on the back is easy to volatilize, and the fatigue feeling is relieved.
The above only is the preferred embodiment of the present invention, not for limiting the scope of the present invention, other applications the equivalent changes of the patent spirit of the present invention all belong to the scope of the present invention.
