Description

Technical Field

[0001] The utility model relates to a bicycle standpipe, in particular to a quick-release fine-tuning standpipe structure with a safety buckle cap. Background Technique

[0002] The common standpipe installation and locking method is to use the screw in the through hole in the circular cover at the rear end of the standpipe to lock the sunflower internal thread in the front fork vertical tube, so as to achieve the purpose of adjusting the angle deflection of the standpipe. When the standpipe angle is adjusted, it is locked with a screw. This standpipe installation method is relatively simple and direct, and adopts a screw locking method, but it has an obvious disadvantage: during cycling, if the standpipe angle deflects due to collision, a torque hex key wrench must be used to adjust the tightness of the screw, and then the purpose of adjusting the standpipe angle can be achieved. Therefore, a hex key wrench must be carried during cycling, otherwise the standpipe angle cannot be adjusted.

[0003] Furthermore, the structures of many types of standpipes on the market are basically fixed to the front fork vertical tube with screws at the front and back. Through the cut of the cylindrical installation body at the rear of the standpipe, the screws are symmetrically locked. This structure is relatively simple. If the angle deflection of the standpipe needs to be adjusted, it needs to be tightened and loosened by screws. If no tools are carried during cycling, it is very easy to cause the standpipe to become loose, and then accidental injuries during cycling will occur, affecting cycling safety and cycling experience, and being not conducive to improving the cycling feeling.

[0019] The present utility model will be described in more detail below with reference to the drawings and embodiments.

[0020] The present utility model discloses a quick-release fine-tuning riser structure with a safety buckle cap, in combination with Figures 1 to 5As shown in the figure, it includes a front fork vertical tube 1, a head tube 2, a fixing seat 3, a locking gasket 4, a riser 5, a pressing handle 6 and a safety cap 7. The head tube 2 is sleeved outside the front fork vertical tube 1. The fixing seat 3 is sleeved on the upper end of the front fork vertical tube 1 and the two are fixedly connected. The riser 5 includes a sleeve 50. The sleeve 50 and the locking gasket 4 are sequentially sleeved outside the fixing seat 3 from top to bottom. The locking gasket 4 is arranged in the sleeve 50 and the two are screwed together. The end 30 at the upper end of the fixing seat 3 penetrates upward above the sleeve 50. Two symmetrically arranged cutting surfaces 31 are formed on the side of the end 30. The safety cap 7 covers the top of the end 30. The left and right flat side walls 70 of the safety cap 7 are respectively in sliding fit with the two cutting surfaces 31. A horizontally extending waist-shaped hole 71 is formed on the flat side wall 70. The pressing handle 6 is located outside the sleeve 50. Two arms 60 extending upward above the sleeve 50 are formed at the upper end of the pressing handle 6. The inner sides of the two arms 60 are respectively aligned with the two flat side walls 70. Limiting screws 61 are respectively arranged at the ends of the two arms 60. The two limiting screws 61 respectively pass through the two waist-shaped holes 71 and are screwed and connected to the cutting surfaces 31. A cam portion 62 protruding downward is formed at the end of the arm 60. Two symmetrically arranged card slots 51 are formed on the upper end surface of the sleeve 50. The two cam portions 62 are respectively arranged in the two card slots 51. When the pressing handle 6 is pressed downward, the two cam portions 62 respectively abut against the bottoms of the two card slots 51. When the pressing handle 6 is lifted upward, the two cam portions 62 are turned upward relative to the two card slots 51.

[0021] In the above structure, the pressing handle 6 and the sleeve 50 adopt a cam cooperation method. When the pressing handle 6 is pressed downward, the two cam portions 62 are in a downward turning state, and the two cam portions 62 respectively abut against the bottoms of the two card slots 51, thereby fastening the riser 5. When the direction of the riser 5 needs to be finely adjusted, only need to lift the pressing handle 6 upward. During the process that the two cam portions 62 are turned upward relative to the two card slots 51, the abutting stress on the bottom of the card slot 51 is removed. At this time, the angle of the riser 5 can be finely adjusted. Then press the pressing handle 6 downward again to fasten the riser 5 again. Based on the above principle, the present utility model is convenient for finely adjusting the angle of the riser, and does not rely on additional tools during the adjustment process, which helps to improve the riding safety and reliability. In addition, the above fine adjustment also has technical characteristics such as easy operation.

[0022] Further, a spring 33 is arranged on one side of the end 30 facing the pressing handle 6. The spring 33 abuts between the end 30 and the inner wall of the safety cap 7. On this basis, please refer to Figure 2, a lower step opening 72 is formed at the lower end of the safety buckle cap 7 near one side of the pressing handle 6, and the upper end of the pressing handle 6 is clamped in the lower step opening 72. When the safety buckle cap 7 is pushed, the lower step opening 72 is separated from the upper end of the pressing handle 6.

[0023] Among them, the lower step opening 72 is used to limit the upper end of the pressing handle 6. Under the elastic force exerted by the spring 33, the lower step opening 72 remains in a state of clamping the upper end of the pressing handle 6. When the user pushes the safety buckle cap 7, the elastic force of the spring 33 needs to be overcome. Until the lower step opening 72 is separated from the upper end of the pressing handle 6, the pressing handle 6 can be pulled upward. Under the cooperation of the lower step opening 72 and the upper end of the pressing handle 6, the pressing handle 6 can be restricted to prevent the pressing handle 6 from malfunctioning due to being touched.

[0024] In order to reliably fix the fixed seat 3, in combination with Figure 2 and Figure 4 as shown, a fastening screw 32 is passed through the axis of the end 30, and the lower end of the fastening screw 32 is screwed and fixed to the upper end of the front fork vertical tube 1.

[0025] As a preferred method, please refer to Figure 2 and Figure 3 , a bowl member 8 and a washer 9 are sleeved on the outer side of the front fork vertical tube 1. The washer 9 and the bowl member 8 are stacked up and down, and the washer 9 and the bowl member 8 are clamped between the fixed seat 3 and the lower end of the front fork vertical tube 1.

[0026] In this embodiment, please refer to Figure 2 and Figure 5 , an arc-shaped fixing piece 34 is fixed on the side of the end 30 facing away from the spring 33, and the arc-shaped fixing piece 34 is aligned with the inner wall of the safety buckle cap 7. Further, the arc-shaped fixing piece 34 and the end 30 are fixedly connected by a lateral screw 35. The arc-shaped fixing piece 34 in this embodiment has a sliding stroke limiting effect on the safety buckle cap 7.

[0027] In order to reliably fix the fixed seat 3 on the front fork vertical tube 1, in this embodiment, a clamp 36 is formed at the lower end of the fixed seat 3. The clamp 36 is sleeved on the outer side of the front fork vertical tube 1, and the two ends of the opening of the clamp 36 are connected by a clamp screw 37.

[0028] In the quick-release fine-tuning riser structure with a safety buckle cap disclosed by the present utility model, when adjusting and locking the angle of the riser, it does not rely on an Allen wrench to loosen the screws. This safety buckle device effectively protects the safety of cycling. In addition, the safety buckle and the safety structure of the pressing handle bayonet can play the role of locking without pushing the safety buckle cap and opening the safety handle when pushing the safety buckle cap, preventing the locking mechanism from loosening, thereby avoiding potential safety hazards.

[0029] The above are only preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, or improvements made within the technical scope of the present utility model shall be included within the scope protected by the present utility model.
