Description

Technical Field

[0001] This utility model relates to the field of electric bicycle parts processing and manufacturing, specifically to an off-road frame clamp. Background Technology

[0002] Off-road electric bicycles, due to their special operating environment, such as rugged mountain roads, steep slopes, and jumps, have extremely high requirements for the strength, rigidity, and precision of the frame beam. As the core load-bearing structure, the beam beam is usually made of high-strength aluminum alloy or chromium-molybdenum steel composite materials, and its processing quality directly affects the safety, handling, and durability of the entire vehicle.

[0003] Currently, the processing of the frame of off-road electric bicycles, such as milling, drilling, and welding, mainly relies on general-purpose fixtures or simple customized tooling. However, these tools suffer from insufficient rigidity. The frame structure is complex and usually has curved surfaces, irregular holes, and welding bevels. Traditional fixtures, such as vises, are difficult to hold stably, and the cutting force can easily cause vibration or deformation during processing, affecting dimensional accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide an off-road beam clamp to solve one of the problems raised in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An off-road beam clamp includes a base, a clamping block, and a locking block. The base has a groove extending from one end to the other. A first inclined surface is provided at one end of the groove, and a second and third inclined surface are provided on both sides of the groove. A protrusion, shaped like a truncated quadrilateral cone, is provided at the bottom of the groove. A through hole penetrating the base is also provided at the bottom of the groove. When the beam is placed within the groove, the clamping block is embedded within the beam, and the locking block presses against the clamping block. The locking block is detachably connected to the base.

[0007] Beneficial effects: By incorporating grooves, a first inclined surface, a second inclined surface, a third inclined surface, and a four-sided frustum-shaped protrusion, rapid positioning and stable clamping of the beam are achieved. Through holes facilitate the installation of other fasteners, resulting in a simple overall fixture structure, convenient installation, and stable clamping.

[0008] Preferably, the clamping block has protrusions on both sides of the side closest to the main beam, and the protrusions on both sides are V-shaped in general, and the protrusions are adapted to the shape of the inner wall surface of the main beam.

[0009] Beneficial effects: The clamping block adopts a V-shaped protrusion design, which is adapted to the shape of the inner wall of the beam. It can fit tightly against the inner wall of the beam, enhance clamping stability, prevent the beam from shifting or rotating under force, and improve the reliability of the clamp.

[0010] Preferably, the length of the locking block is greater than the width of the main beam, and when the locking block presses over the pressing block, each end of the locking block forms a 5-10cm overhang.

[0011] Beneficial effects: By limiting the length of the locking block to be greater than the width of the main beam and forming a cantilever, the locking block can apply force evenly, avoiding local stress concentration. It also facilitates installation and disassembly, improving operational convenience.

[0012] Preferably, the locking block has U-shaped holes on both sides, and the base has corresponding threaded holes.

[0013] Beneficial effects: The use of a U-shaped hole and threaded hole combination allows for fine-tuning of the locking block during installation to accommodate beams of different sizes, improving the versatility and adaptability of the fixture.

[0014] Preferably, the top plane of the protrusion is 10-15mm lower than the opening plane of the groove, and the inclination angle formed by the four sides of the protrusion and the bottom surface is 15°-30°.

[0015] Beneficial effects: Optimizing the height and tilt angle of the protrusions provides stable support and facilitates quick alignment and installation of the main beam, reducing assembly time and improving work efficiency.

[0016] Preferably, the locking block has an elastic buffer layer on the side near the clamping block.

[0017] Preferably, the thickness of the elastic buffer layer is 2-5 mm.

[0018] Preferably, the elastic buffer layer is polyurethane or rubber.

[0019] Beneficial effects: An elastic buffer layer between the locking block and the clamping block can absorb vibration and impact, prevent the surface of the beam from being damaged by rigid clamping, and at the same time enhance the friction of clamping, prevent the beam from loosening in a vibrating environment, and improve the durability and safety of the clamp.

Specifically, the top plane of the protrusion 8 is 10-15mm lower than the opening plane of the groove 4. In this embodiment, the top plane of the protrusion 8 is 12mm lower than the opening plane of the groove 4.

[0028] The four sides of the protrusion 8 form an inclination angle of 15°-30° with the bottom surface. In this embodiment, the four sides of the protrusion 8 form an inclination angle of 20° with the bottom surface.

[0029] The bottom of the groove 4 is provided with a through hole 9 that penetrates the base 1; when the main beam is placed in the groove 4, the clamping block 2 is embedded in the main beam, the locking block 3 is pressed on the top of the clamping block 2, and the locking block 3 is detachably connected to the base 1.

Specifically, the thickness of the elastic buffer layer is 3 mm, and the elastic buffer layer is made of polyurethane or rubber. The surface of the elastic buffer layer is also provided with transverse anti-slip grooves to enhance friction and absorb vibration.

[0034] Installation process: Place the main beam into the groove 4 of the base 1, so that the end of the main beam fits against the first inclined surface 5, and the two side walls of the main beam contact the second inclined surface 6 and the third inclined surface 7.

[0035] Embed the clamping block 2 inside the main beam so that the V-shaped protrusion 10 is tightly attached to the inner wall of the main beam.

[0036] Place the locking block 3 over the clamping block 2, adjust the position of the U-shaped hole 11 so that the bolt passes through the U-shaped hole 11 and is screwed into the threaded hole 13 of the base 1.

[0037] Tighten the bolts to press the locking block 3 against the clamping block 2.

[0038] In another embodiment, the elastic buffer layer is made of 5mm thick rubber material, and the tilt angle of the protrusion 8 is adjusted to 25°, which is suitable for fixing larger beams.
