Description

Technical Field

[0001] This utility model relates to the field of bicycle wheel rim rounding technology, specifically a bicycle wheel rim rounding device. Background Technology

[0002] As people's living standards improve, more and more people are using bicycles. They can exercise and save energy. Bicycle rims are bicycle components that are adjusted less frequently. Adjustments are only needed when the rims become elliptical or deviate due to road bumps, collisions, broken spokes, or other reasons. Therefore, a rim adjustment device is required.

[0003] Existing wheel rim rounding devices typically round the raised parts on the rim surface by squeezing them to gradually flatten them. However, during the squeezing process, the operator directly squeezes the rim without being able to control the squeezing speed. As a result, the rim is easily damaged by sudden impact forces. To address this issue, we propose a bicycle wheel rim rounding device. Utility Model Content

[0004] The purpose of this invention is to provide a bicycle wheel rim adjustment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bicycle wheel rim adjustment device, comprising a base, a support plate fixedly installed on the top of the base, a fixing ring fixedly installed on the side of the support plate, an electric push rod provided on the side of the support plate, the electric push rod being fixedly connected to the side of the support block, a clamping plate fixedly installed on the side of the support block, the base being penetrated by a movable plate and slidably connected to the movable plate, a pressure plate fixedly installed on the top of the movable plate, and a control component provided inside the base, the control component comprising: a fixing block, a sliding plate, a spring, a movable block, and an adjusting component;

[0006] The fixed block is connected to the spring via a sliding plate; the movable block is used to push the movable plate to move; the adjusting component is used to squeeze the wheel rim, thereby slowing down the movement speed of the movable block and the pressure plate, and preventing the wheel rim from breaking due to excessive impact force caused by excessive movement speed.

[0007] Preferably, the fixed block has a triangular cross-section and is fixedly installed on the side of the slide plate. The side of the slide plate is fixedly connected to one end of the spring, and the other end of the spring is fixedly installed on the inner wall of the movable plate. When the cross-section of the fixed block is no longer in contact, the slide plate can bounce up under the action of the spring.

[0008] Preferably, the adjusting component includes a flat rod, which is fixedly installed on the inner wall of the movable plate. The flat rod passes through the slide plate and is slidably connected to it. The flat rod ensures the stability of the slide plate during movement.

[0009] Preferably, the movable block has a through hole, and a support rod is fixedly installed on the inner wall of the through hole. When the movable block moves, the support rod fixed on the inner wall of the movable block can slide synchronously.

[0010] Preferably, the side of the movable block is fixedly connected to the hydraulic rod, the hydraulic rod is fixedly installed on the inner wall of the base, the top of the movable block is fixedly connected to the bottom of the movable plate, and the hydraulic rod can push the movable block to slide within the base.

[0011] Preferably, a protrusion is fixedly installed on the inner wall of the base. The cross-sectional shape of the protrusion is triangular. The protrusion can slow down the movement speed of the moving block when the cross-section of the fixed block is squeezed.

[0012] Preferably, the support rod is slidably connected to the arc-shaped groove, the arc-shaped groove is formed on the arc surface of the round rod, the round rod passes through the base and is rotatably connected to the base, and a fan blade is fixedly installed on the side of the round rod. When the support rod slides in the arc-shaped groove, the round rod can be forced to drive the fan blade to rotate.

[0013] Compared with the prior art, this utility model provides a bicycle wheel rim rounding device, which has the following beneficial effects:

[0014] 1. This bicycle wheel rim rounding device, through the installation of control components, allows the hydraulic rod to push the moving block to slide on the inner wall of the base. The moving plate fixed to the surface of the moving block can drive the clamping plate to move towards the fixed ring. During the movement of the moving block, the protrusions fixed to the inner wall of the base will abut against the tangential surface of the fixed block. When the tangential surface of the fixed block is abutted, the sliding plate fixed to the surface of the fixed block can slide on the surface of the flat rod. Since there are multiple sets of protrusions, the fixed block can be squeezed multiple times, thereby slowing down the movement speed of the moving block and the pressure plate, and avoiding wheel rim breakage due to excessive impact force caused by excessive movement speed.

[0015] 2. This bicycle wheel rim rounding device, through the setting of an adjusting component, allows the support rod fixed to the inner wall of the moving block to slide within the arc-shaped groove opened on the surface of the round rod during the movement of the moving block. The round rod can then drive the fan blade to rotate. When the fan blade can no longer rotate, it indicates that the pressure plate has been fully compressing the wheel rim and no further pushing is required. This serves as a reminder to the operator and avoids damage to the wheel rim due to excessive compression. Attached Figure Description

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a bicycle wheel rim adjusting device, including a base 1, a support plate 2 fixedly installed on the top of the base 1, a fixing ring 3 fixedly installed on the side of the support plate 2, an electric push rod 4 provided on the side of the support plate 2, the electric push rod 4 being fixedly connected to the side of the support block 5, a clamping plate 6 fixedly installed on the side of the support block 5, a movable plate 7 penetrating the base 1 and slidably connected to the movable plate 7, a pressure plate 8 fixedly installed on the top of the movable plate 7, and a control component 9 provided inside the base 1, the control component 9 including: a fixing block 91 and a sliding plate. 92, spring 93, moving block 94 and adjusting component 95. During the movement of moving block 94, the protrusion 955 fixed to the inner wall of base 1 will abut against the cut surface of fixed block 91. When the cut surface of fixed block 91 is abutted, the sliding plate 92 fixed to the surface of fixed block 91 can slide on the surface of flat rod 951. Since there are multiple sets of protrusions 955, fixed block 91 can be squeezed multiple times, thereby slowing down the movement speed of moving block 94 and pressure plate 8, and avoiding the wheel rim from breaking due to excessive impact force caused by excessive movement speed.

[0022] The fixed block 91 has a triangular cross-section and is fixedly installed on the side of the slide plate 92. The side of the slide plate 92 is fixedly connected to one end of the spring 93, and the other end of the spring 93 is fixedly installed on the inner wall of the movable plate 7. When the cross-section of the fixed block 91 is no longer in contact, the slide plate 92 can spring up under the action of the spring 93. The adjusting component 95 includes a flat rod 951, which is fixedly installed on the inner wall of the movable plate 7. The flat rod 951 passes through the slide plate 92 and is slidably connected to the slide plate 92. The flat rod 951 ensures the stability of the slide plate 92 during movement. The movable block 94 has a through hole 952, and a support rod 953 is fixedly installed on the inner wall of the through hole 952. When the movable block 94 moves, the support rod 953 fixed on the inner wall of the movable block 94 can slide synchronously. The side of the movable block 94 is fixedly connected to the hydraulic rod 954, which is fixedly installed on the inner wall of the base 1. The top of the movable block 94 is fixedly connected to the bottom of the movable plate 7. The hydraulic rod 954 can push the movable block 94 to slide within the base 1. A protrusion 955 is fixedly installed on the inner wall of the base 1. The cross-sectional shape of the protrusion 955 is triangular. The protrusion 955 can slow down the movement speed of the movable block 94 when the cross-section of the fixed block 91 is squeezed. The support rod 953 is slidably connected to the arc groove 957, which is opened on the arc surface of the round rod 956. The round rod 956 passes through the base 1 and is rotatably connected to the base 1. A fan blade 958 is fixedly installed on the side of the round rod 956. When the support rod 953 slides within the arc groove 957, the round rod 956 can be forced to rotate the fan blade 958.

[0023] In this invention, during use, the wheel rim to be rounded is fitted onto the surface of the fixing ring 3. After fitting, the flat side is brought close to the clamping plate 6, and the raised side is rotated to the position to be rounded. Then, the electric push rod 4 is driven to move the clamping plate 6 to fix the flat side of the wheel rim. After fixing, the electric push rod 4 pushes the moving block 94 to slide within the base 1. When the moving block 94 moves, the moving plate 7 fixed to the top of the moving block 94 can drive the clamping plate 6 to move synchronously towards the fixing ring 3. During the movement of the moving block 94, the protrusion 955 fixed to the inner wall of the base 1 will abut against the cut surface of the fixing block 91. When the cut surface of the fixing block 91 is abutted, the sliding plate 92 fixed to the surface of the fixing block 91 can slide on the surface of the flat rod 951. Since there are multiple sets of protrusions 955, the fixing block 91 can be squeezed multiple times. The pressure plate 8 slows down the movement of the moving block 94 and the pressure plate 8, preventing the wheel rim from breaking due to excessive impact caused by excessive movement speed. After the pressure plate 8 contacts the protruding part of the wheel rim, it squeezes the protruding part to make it fit against the surface of the fixed ring 3, thereby completing the rounding process. At the same time, during the movement of the moving block 94, the support rod 953 fixed to the inner wall of the moving block 94 will slide in the arc groove 957 opened on the surface of the round rod 956, so the round rod 956 can drive the fan blade 958 to rotate. When the fan blade 958 can no longer rotate, it means that the pressure plate 8 is in a state of fully squeezing the wheel rim and no further pushing is needed. This can achieve the purpose of reminding the operator to avoid damage to the wheel rim due to excessive squeezing. Then the operator stops the movement of the hydraulic rod 954, and the pressure plate 8 can keep the wheel rim in a state of squeezing for rounding.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
