Description

Mini multifunctional bicycle disc correcting tool

Technical Field

The utility model relates to a portable bicycle tool, in particular to a bicycle disc correcting tool.

Background

The disc brake type bicycle brake system has the advantages that the brake performance is colored and the weight is light, the disc brake type bicycle brake system is more and more popular with people, and particularly, the proportion of the disc brake system adopted by middle-high-end bicycles is increased every year. However, the disc in the disc brake system is thin, so that the disc can be thermally deformed during continuous long-time braking, and is easily deformed after collision, and the disc can also rub against a linen pad when the brake is not performed after the deformation of the brake disc, so that the riding is difficult. At this time, the brake disc needs to be corrected to reduce deflection, and a disc correcting wrench is used, but the general disc correcting wrench is long and heavy and is not suitable for being carried outdoors. In addition, the bicycle chain is in daily use, the probability of failure is relatively low, which is the reason that a plurality of portable tools of the bicycle are integrated with the chain cutter, the bicycle can be continuously ridden after the chain is cut off when the chain fails and then the chain quick connecting buckle is replaced, but the chain cutter is inconvenient to use for the integrated design, and the integrated weight is not light enough.

Disclosure of Invention

In order to solve the problem, the utility model provides a mini multi-functional bicycle video disc corrects instrument, its aim at provides a small-size video disc of integrated chain cutter and corrects the spanner, only needs six spanners in the 6mm of cooperation, just can correct work and chain cut work to bicycle brake video disc, and the volume is very little, conveniently carry.

In order to achieve the above object, the present invention provides a mini multi-functional bicycle disc correction tool, which is implemented as follows: the chain cutting device is composed of a chain cutting device, a bracket, a hand-screwed bolt, a six-inner-angle long hole and a chain cutting ejector rod bolt, and an L-shaped 6mm inner hexagonal wrench is needed to work in a matching mode when the chain cutting device is used. When the bicycle disc is corrected, the long end of the inner hexagonal wrench is inserted into the hexagonal long hole, the bolt is screwed by hand to lock and fix the inner hexagonal wrench, and the bicycle disc is pried by utilizing the gap between the short end of the inner hexagonal wrench and the bracket, so that the purpose of correcting the disc is achieved; when the chain is cut off, the bracket is used as a handle to hold the chain, the inner hexagonal wrench is inserted into the chain cutting ejector rod bolt, and the inner hexagonal wrench is broken to cut off the chain.

Because the utility model discloses a multi-functional miniaturized structure to can obtain following beneficial effect: light small and exquisite, resources are saved makes things convenient for the open air to ride and carries.

in the figure, (1) a chain cutter, (2) a bracket, (3) a hand-screwed bolt, (4) a six-internal-angle long hole, (5) a chain-cutting ejector rod bolt, (6) an internal hexagonal wrench, (7) a long end, (8) a short end and (9) a bicycle disc.

Detailed Description

As shown in figure 1, the utility model discloses contain chain cutter (1), bracket (2), hand screwed bolt (3), six interior angle slot holes (4), chain cut ejector pin bolt (5), chain cutter (1) and bracket (2) are respectively on both sides, and the centre is six interior angle slot holes (4), is hand screwed bolt (3) below bracket (2), and chain cutter (1) is above-mentioned chain cut ejector pin bolt (5), and hand screwed bolt (3) and chain cut ejector pin bolt (5) can be dismantled the separation. As shown in fig. 2, when a bicycle disc (9) is corrected, an L-shaped 6mm inner hexagon wrench (6) is needed to work in a matching manner, the long end (7) of the inner hexagon wrench (6) is inserted into the six inner angle long hole (4), the long six inner angle long hole (4) effectively limits the left and right deflection of the inner hexagon wrench (6) during working, then the inner hexagon wrench (6) is pressed by screwing a bolt (3) by hand to prevent the inner hexagon wrench from sliding up and down, so that the inner hexagon wrench (6) is well fixed, a gap is formed between the short end (8) of the inner hexagon wrench (6) and the bracket (2), and the gap is clamped into the bicycle disc (9) to be corrected to pry the bicycle disc (9) so as to correct the bicycle disc. As shown in figure 3, when the chain cutting work is needed, the bracket (2) is used as a handle to hold and is matched with the inner hexagonal wrench (6) to work together, the short end (7) of the inner hexagonal wrench (6) is inserted into the top of the chain cutting ejector rod bolt (5), and the long end (7) is pulled to work.

In shape, construction and combination thereof, the utility model discloses with the common essential technical features of closest prior art: a bicycle disc correcting tool and a bicycle chain cutter.

In shape, structure and combination thereof, the technical features of the utility model different from the closest prior art are: a multifunctional tool for correcting a disc by using a bracket and an internal hexagonal wrench.

The utility model discloses a theory of operation and working process as follows: the utility model discloses contain chain cutter (1), bracket (2), hand are twisted bolt (3), six interior angle slot hole (4), chain cutting ejector pin bolt (5), chain cutter (1) and bracket (2) are respectively on both sides, and the centre is six interior angle slot hole (4), is hand below bracket (2) and twists bolt (3), and the higher authority of chain cutter (1) is chain cutting ejector pin bolt (5), and the separation can be dismantled to hand twisting bolt (3) and chain cutting ejector pin bolt (5). When correcting bicycle disc (9), need an L type 6 mm's interior hexagonal spanner (6) cooperation work, insert in six interior angle slot hole (4) long end (7) of interior hexagonal spanner (6), longer six interior angle slot hole (4) have effectively restricted interior hexagonal spanner (6) during operation side to side deflection, rethread hand-twist bolt (3) compress tightly interior hexagonal spanner (6) in order to prevent it from sliding from top to bottom, thereby carry out better fixed to interior hexagonal spanner (6), form a clearance between short end (8) of interior hexagonal spanner (6) and bracket (2), utilize this clearance card to block bicycle disc (9) and need correct the department and pry, carry out disc correction work. When the chain is required to be cut off, the bracket (2) is used as a handle to be held and is matched with the inner hexagonal wrench (6) to work together, the short end (7) of the inner hexagonal wrench (6) is inserted into the top of the chain cutting ejector rod bolt (5), and the long end (7) is pulled to work.

Realize the best scheme of the utility model: adopt the hard metal material preparation, utilize current industrial equipment, batch production to reach and realize the utility model discloses a practical value and economic value.
