Description

Bicycle connects device for quickly disassembling

Technical field:

The utility model relates to technical field of bicycles, more specifically to bonded assembly device for quickly disassembling between the cycle frame and the handrail person in charge.

Background technology:

As shown in Figure 1, bonded assembly device for quickly disassembling a is fixed on the bearing e that is welded as a whole with handrail person in charge c between cycle frame b and the handrail person in charge c now, during use, pushes the plectrum d of device for quickly disassembling a downwards, bayonet socket among the device for quickly disassembling a leaves ring washer, just can take apart.Its weak point is: 1, because it self structure only easily will be pushed the plectrum d that office is designed to flats, feel bitterly also easily scratches finger when using plectrum d to push, and is very dangerous.2, because the principal direction of device for quickly disassembling A is upwards to be fixed on the bearing e, be subject to the rainwater etch during use, thereby it is easy to become rusty the dead service life that shortens product.3, simultaneously because it self structure, the product poor sensitivity because of kayser is tiny with spring, is easy to damage losing self-lock ability.

The utility model content:

The utility model is exactly at above-mentioned device for quickly disassembling safety, poor sensitivity, the dead deficiency of becoming rusty easily inadequately, and provide a kind of bicycle to connect device for quickly disassembling, its safety performance is good, use comfortable feel, separates to connect conveniently, and outward appearance is good. and product is highly sensitive, be not easy to get rusty, long service life.

Technology solution of the present utility model is as follows:

Bicycle connects device for quickly disassembling, and it is made up of quick detach lock and permanent seat two parts, and the quick detach lock is made up of depression bar, Connection Block, banking stop, stage clip, base, card;

Have position-limited trough on the body of rod of depression bar, the bottom has accepting hole, has through hole, screw thread on the Connection Block, has negative thread, card installing space in the base, card is row shape and have blocking step, springy column head, axis hole;

Through hole and Connection Block that depression bar passes on the Connection Block are nested together, banking stop is fastened in the position-limited trough on the depression bar, compression spring sleeve is on depression bar, and on the step in the built-in space of base, the screw thread of the negative thread of base on Connection Block is screwed onto an end application force in banking stop, other end application force;

The axis hole of card is articulated in the bottom of base, and places the card installing space, and the step outside of card takes the form of inclined plane, and two springy column heads stretch in the accepting hole of depression bar;

Permanent seat by the pedestal of hollow, be arranged in back-up ring, the step bearing fixed seat in vacancy form, the blocking step of card is fastened on the bottom of back-up ring.

Bearing carrier ring is in the bottom of base and drop on the step bearing fixed seat of pedestal.

The top of described depression bar has circular pressure handle.

One-body molded on the described pedestal have a connecting panel, and connecting panel is fixed on the bearing.

The beneficial effects of the utility model are: (1), press depression bar the blocking step of card is regained, thus realize quick detach.Adopt depression bar to realize quick detach, can not scratch finger, comfortable feel, safety performance is good; (2), the principal direction of quick detach lock is to be fixed on downwards on the bearing, has the semisphere pressure handle to pick up a grade rainwater, can prevent etch, when need not also being difficult for getting rusty for a long time, thereby prolongs the service life of product; (3), the structure that adopts of the utility model compared with prior art, the product sensitivity is higher, uses more convenient fast.

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is the prior art constructions scheme drawing;

Fig. 2 is the utility model installation site scheme drawing;

Fig. 3 is the utility model cutaway view;

Fig. 4 is the later-model sectional exploded view of this reality;

Fig. 5 is the three-dimensional exploded view of quick detach lock part;

Fig. 6 is the schematic perspective view of permanent seat.

The specific embodiment:

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

Embodiment sees Fig. 2～6, and bicycle connects device for quickly disassembling, and it is made up of quick detach lock A and permanent seat B two parts,

Quick detach lock A is made up of depression bar 1, Connection Block 2, banking stop 3, stage clip 4, base 5, card 6;

Have position-limited trough 12 on the body of rod of depression bar 1, the bottom has accepting hole 13, has through hole 21, screw thread 22 on the Connection Block 2, has negative thread 52, card installing space 51 in the base 5, card 6 is row shape and have blocking step 61, springy column head 62, axis hole 63;

The through hole 21 that depression bar 1 passes on the Connection Block 2 is nested together with Connection Block 2, banking stop 3 is fastened in the position-limited trough 12 on the depression bar 1, stage clip 4 is enclosed within on the depression bar 1, on the step 53 in base 5 built-in spaces, the screw thread 22 of the negative thread 52 of base 5 on Connection Block 2 is screwed onto one end application force in banking stop 3, other end application force;

The axis hole 63 of card 6 is articulated in the bottom of base 5, and places card installing space 51, and step 61 outsides of card 6 take the form of inclined plane, and two springy column heads 62 stretch in the accepting hole 13 of depression bar 1;

Permanent seat B by the pedestal 8 of hollow, be arranged in back-up ring 81, the step bearing fixed seat 82 in vacancy form, the blocking step 61 of card 6 is fastened on the bottom of back-up ring 81;

Bearing 7 is enclosed within the bottom of base 5 and drops on the step bearing fixed seat 82 of pedestal 8.

The top of depression bar 1 has circular pressure handle 11.

Pedestal 8 is one-body molded connecting panel 83, and connecting panel 83 is fixed on the bearing C.

Principle of work: during use, permanent seat B is spirally connected to be fixed tightly in handrail by connecting panel 83 is responsible on the bearing C be fixed as one, quick detach lock A sleeve inserts permanent seat B then in the default mounting hole of vehicle frame front end.

When quick detach lock A inserted permanent seat B, the inclined-plane, step 61 outside of elastic card 6 was subjected to back-up ring 81 inside squeese pressures and can inwardly shrinks, and caused that step 61 is crossed back-up ring 81 and the bottom that is fastened on back-up ring automatically.When the needs quick detach, press moulded rod 1, the accepting hole of the bottom of depression bar 1 13 can give the row 62 of card 6 inside thrust, causes that the step 61 of card inwardly shrinks, and step 61 can upwards be crossed back-up ring 81 like this, from permanent seat B, extract out, thus the realization quick detach.

The utility model is to have adopted depression bar 1 to push the realization quick detach unlike the prior art, and the top of depression bar 1 is provided with pressure handle 11, and pressure handle 11 is hemisphere circles, can not feel the hand pain and scratch finger, makes safety performance good, and is laborsaving convenient.

The principal direction of quick detach lock A is to be fixed on downwards on the permanent seat B, because of pressure handle is semi-spherical shape, can sweep rainwater, when raining, rainwater can not flow directly in the space of quick detach lock A and cause etch, when need not being difficult for getting rusty for a long time, thereby prolongs the service life of product yet.

Because the architectural feature of this product makes that the product sensitivity is higher.During use, only need just can realize loading onto, taking apart by moulded rod 1, very convenient quick.
