Description

Technical Field

[0001] This utility model relates to the technical field of clamp-on bicycle speedometers, and more particularly to a clamp-on bicycle speedometer. Background Technology

[0002] A cycling computer is an electronic device installed on bicycles, motorcycles, and cars to record and display various riding data, such as current speed, riding distance, and riding time. High-end cycling computers also have displays for altitude, air pressure, and gradient.

[0003] The inventor discovered during daily use of the cycling computer that a typical cycling computer is usually attached to the bicycle handlebars by a ring and secured with screws. This makes it inconvenient to remove the cycling computer from the handlebars when it is not in use, which causes problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a clamp-on bicycle speedometer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a clamp-type bicycle speedometer, comprising a speedometer, a round rod fixedly connected to the surface of the speedometer, a disassembly and assembly device provided on the side of the round rod, the disassembly and assembly device comprising a semi-circular ring provided on the side of the round rod, a rectangular plate fixedly connected to the side of the semi-circular ring, a through groove being provided on the side of the rectangular plate, a protrusion fixedly connected to the surface of another rectangular plate, and a retaining ring fixedly connected to the surface of the protrusion.

[0006] The effect achieved by the above components is that, under the action of the retaining ring, the protrusion can be fixed to the inner wall of the through groove, thereby clamping the speedometer onto the handlebars of the bicycle.

[0007] Preferably, a washer, which is a rubber ring, is fixedly connected to the side of the rectangular plate.

[0008] The effect achieved by the above components is that, under the action of the washers, the rectangular plates will not come into direct contact, thus avoiding the deformation of the rectangular plates caused by rigid contact.

[0009] Preferably, the rectangular plate is threaded with bolts on its side, and the bolts are inserted into the interior of the protrusion.

[0010] The effect achieved by the above components is that, under the action of the bolts, the protrusion is fixed inside the through groove, thereby fixing the speedometer to the surface of the handlebars.

[0011] Preferably, anti-slip strips are fixedly connected to the side of the semicircular ring, and the anti-slip strips are evenly arranged on the inner wall of the semicircular ring.

[0012] The aforementioned components achieve the following effects: The anti-slip strip prevents the speedometer from sliding on the handlebar surface, thus preventing speedometer displacement. To disassemble the speedometer, unscrew the bolts to open the semi-circular ring and remove it. To fix the speedometer to the handlebar surface, place the semi-circular ring on the handlebar surface; the anti-slip strip prevents the speedometer from sliding, again preventing displacement. Rotate the other semi-circular ring to insert the protrusion into the through groove. The washer prevents direct contact between the rectangular plates, avoiding deformation caused by rigid contact. Screw the bolts into the protrusion by hand to fix it in place within the through groove, thus achieving the desired fixation and assembly / disassembly.

[0013] Preferably, the surface of the round rod is provided with a replacement device, the replacement device including a sleeve rod sleeved on the surface of the round rod, a ring fixedly connected to the surface of the round rod, the ring being a rubber ring, and a semi-circular ring fixedly connected to one end of the sleeve rod.

[0014] The effect achieved by the above components is that, under the action of the sleeve rod and the ring, the sleeve rod can be locked onto the surface of the ring rod, thereby achieving the function of replacement.

[0015] Preferably, the inner wall of the sleeve rod is provided with a sliding groove, and a locking block is fixedly connected to the surface of the round rod.

[0016] The effect achieved by the above components is that, under the action of the slide and the locking block, the sleeve rod will not rotate when it is replaced.

[0017] Preferably, a pad is fixedly connected to one end of the round rod, and the pad is a rubber block.

[0018] The effect achieved by the above components is that, under the action of the pad, the round rod will not come into contact with the inner wall of the sleeve rod, thus avoiding the phenomenon of rigid contact.

[0019] Preferably, the surface of the sleeve rod is threaded with a screw, and the surface of the round rod is provided with a groove, into which the screw is inserted.

[0020] The aforementioned components achieve the following effects: Under the action of the screw, the sleeve is fixed to the surface of the round rod, thus achieving a fixing function. When the semi-circular ring needs to be replaced, the sleeve is placed on the surface of the round rod, and the locking block is inserted into the inside of the groove. Thus, the sleeve will not rotate during replacement. Under the action of the round ring, the sleeve can be locked onto the surface of the round rod. The screw is inserted into the inside of the groove, thus fixing the sleeve to the surface of the round rod, thereby achieving the replacement function.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, a disassembly and assembly device is provided. When the odometer needs to be disassembled, the bolt is unscrewed to open the semi-circular ring, allowing the odometer to be removed. When the odometer needs to be fixed to the handlebar surface, the semi-circular ring is placed on the handlebar surface. The anti-slip strip prevents the odometer from sliding on the handlebar surface, thus achieving the phenomenon of odometer displacement. The other semi-circular ring is rotated, allowing the protrusion to be inserted into the through groove. The washer prevents the rectangular plate from directly contacting the odometer, avoiding deformation caused by rigid contact. The bolt is then screwed into the protrusion by hand, fixing the protrusion inside the through groove, thus achieving the fixing function. This solves the problem of the odometer being inconvenient to disassemble and assemble from the handlebar. Attached Figure Description

[0027] Example 1, such as Figure 1-3 As shown, a clamp-on bicycle speedometer 1 includes a speedometer 1, a round rod 4 fixedly connected to the surface of the speedometer 1, and a disassembly / removal device 2 provided on the side of the round rod 4. The bicycle speedometer 1 captures information about the rotation of the bicycle rim through an inductive magnet and a sensor mounted on the spokes of the bicycle's front wheel. The sensor transmits the information to the speedometer 1 via a sensor line. The speedometer 1 calculates and processes this information to display data such as speed and mileage. In addition, some high-end speedometers 1 also have GPS functionality, which can record and display more detailed data, such as riding track and altitude.

[0028] Reference Figure 2The disassembly / assembly device 2 includes a semi-circular ring 21 on the side of the round rod 4. A rectangular plate 22 is fixedly connected to the side of the semi-circular ring 21. A through groove 24 is opened on the side of the rectangular plate 22. A protrusion 23 is fixedly connected to the surface of another rectangular plate 22. A retaining ring is fixedly connected to the surface of the protrusion 23. Under the action of the retaining ring, the protrusion 23 can be fixed to the inner wall of the through groove 24, thereby clamping the odometer 1 onto the handlebars of the bicycle. A washer 26 is fixedly connected to the side of the rectangular plate 22. The washer 26 is a rubber ring. Under the action of the washer 26, the rectangular plate 22 will not directly contact the odometer 22, avoiding the phenomenon of deformation of the rectangular plate 22 due to rigid contact. A bolt 25 is threadedly connected to the side of the rectangular plate 22. The bolt 25 is inserted into the interior of the protrusion 23. Under the action of the bolt 25, the protrusion 23 is fixed inside the through groove 24, thereby fixing the odometer 1 onto the surface of the handlebars. An anti-slip strip 27 is fixedly connected to the side of the semi-circular ring 21 to prevent slippage. The sliders 27 are evenly arranged on the inner wall of the semicircular ring 21. Under the action of the anti-slip strips 27, the speedometer 1 will not slide on the surface of the handlebars, thus achieving the phenomenon of speedometer 1 displacement. When it is necessary to disassemble the speedometer 1, the bolts 25 are unscrewed to open the semicircular ring 21 and remove the speedometer 1. When it is necessary to fix the speedometer 1 to the surface of the handlebars, the semicircular ring 21 is placed on the surface of the handlebars. Under the action of the anti-slip strips 27, the speedometer 1 will not slide on the surface of the handlebars, thus achieving the phenomenon of speedometer 1 displacement. The other semicircular ring 21 is rotated, thus inserting the protrusion 23 into the through groove 24. Under the action of the washer 26, the rectangular plate 22 will not directly contact, avoiding the phenomenon of deformation of the rectangular plate 22 due to rigid contact. The bolts 25 are screwed into the protrusion 23 by hand, thus fixing the protrusion 23 into the through groove 24, thus achieving the fixing function, thereby achieving the function of disassembly and assembly.

[0029] Reference Figure 3A replacement device 3 is provided on the surface of the round rod 4. The replacement device 3 includes a sleeve 31 fitted onto the surface of the round rod 4, a ring 32 (rubber ring) fixedly connected to the surface of the round rod 4, and a semi-circular ring 21 fixedly connected to one end of the sleeve 31. Under the action of the sleeve 31 and the ring 32, the sleeve 31 can be locked onto the surface of the round rod 4, thereby achieving the replacement function. A sliding groove 35 is provided on the inner wall of the sleeve 31, and a locking block 33 is fixedly connected to the surface of the round rod 4. Under the action of the sliding groove 35 and the locking block 33, the sleeve 31 will not rotate during replacement. A pad 34 (rubber block) is fixedly connected to one end of the round rod 4. Under the action of the pad 34, the round rod 4 will not be locked onto the sleeve 31. The inner wall contact avoids rigid contact. The surface of the sleeve rod 31 is threaded with a screw 36, and the surface of the round rod 4 is provided with a groove 37. The screw 36 is inserted into the groove 37. Under the action of the screw 36, the sleeve rod 31 is fixed to the surface of the round rod 4, thereby achieving the function of fixation. When the semi-circular ring 21 needs to be replaced, the sleeve rod 31 is sleeved on the surface of the round rod 4, and the locking block 33 is inserted into the sliding groove 35. Thus, the sleeve rod 31 will not rotate during replacement. Under the action of the ring 32, the sleeve rod 31 can be locked on the surface of the round rod 4. The screw 36 is inserted into the groove 37, thereby fixing the sleeve rod 31 to the surface of the round rod 4, thus achieving the function of replacement.

[0030] Working principle: When using the clamp-on bicycle speedometer 1, the speedometer 1 captures information about the rim rotation via an inductive magnet and sensor mounted on the front wheel spokes. The sensor transmits this information to the speedometer 1 via a sensor line. The speedometer 1 calculates and processes this information to display data such as speed and mileage. Furthermore, some high-end speedometers 1 also have GPS functionality, which can record and display more detailed data, such as riding track and altitude. When disassembling the speedometer 1, the bolt 25 is unscrewed, opening the semi-circular ring 21 and removing the speedometer 1. When fixing the speedometer 1 to the handlebar surface, the semi-circular ring 21 is fitted onto the handlebar surface. The anti-slip strip 27 prevents the speedometer 1 from sliding on the handlebar surface, thus achieving the phenomenon of speedometer 1 displacement. Rotating the other semi-circular ring 21 inserts the protrusion 23 into the through slot 24. The washer 26 prevents the rectangular plate 22 from directly contacting the metal, thus avoiding deformation caused by rigid contact. The bolt 25 is screwed into the protrusion 23 by hand, fixing the protrusion 23 inside the through groove 24, thereby achieving the fixing function and thus the disassembly and assembly function. When the semi-circular ring 21 needs to be replaced, the sleeve 31 is placed on the surface of the round rod 4, and the locking block 33 is inserted into the sliding groove 35, so that the sleeve 31 will not rotate during replacement. Under the action of the ring 32, the sleeve 31 can be locked on the surface of the round rod 4. The screw 36 is inserted into the groove 37, thereby fixing the sleeve 31 on the surface of the round rod 4, thus achieving the replacement function.
