Abstract

The utility model relates to a damping inflator set under a saddle pipe, which is hidden under a saddle. The inflator is fixed under the saddle through a bracket which is movable connected with a saddle bracket, and is fixedly locked through a position limiting pin. The function that the inflator can be matched with any saddle is realized. In addition, the bracker is additionally provided with a pin seat which is connected with a return light box of the bicycle. The return light box can reflect the return light as well as be taken as a container for putting an air conveying pipe. An air nozzle adopts the american system air nozzle series form and the british system air nozzle series form. The utility model has the advantage of broader application.

Description

Damping saddle pipe pump

The utility model relates to a kind of bicycle with car recessive type pump, particularly a kind of hidden below saddle the pump in the saddle pipe.

Existing bicycle has Chinese patent ZL94239217.5 and ZL97234365.2 with car recessive type pump.Both all are that pump is hidden under saddle and in the saddle pipe, form in the base pump by inflator, Pillar for saddle and saddle and include handle, piston pulling rod, upper cover, housing, cylindrical shell, one-way valve, cylindrical shell end socket, pneumatic tube and gas transmission mouth etc. and constitute.The latter is than the former inflator good airproof performance, inflates rapid operation, can adapt to the valve of the multiple gas transmission operation of bicycle and motorcycle in addition.But the common issue with that the above two exist is: must supporting specific saddle, and must a placement container be set specially for tracheae, this class is brought necessarily to the user lacked versatility with car recessive type pump easily, in addition, inflator pressure is little, aeration speed is slower, and the valve type is single, can not adapt to social demand.

The purpose of this utility model provide a kind of can with the damping saddle pipe pump that any bicycle saddle is complementary, tracheae is hidden, inflation is quick and the valve versatility is good.

The utility model comprises handle, cylindrical shell and the tracheae that is connected with the frame of cylindrical shell, the upper end that it is characterized in that cylindrical shell is enclosed within the mesopore of support, the side arm of support flexibly connects by the carriage of bearing pin and saddle below, the through hole that position limit pin runs through on the side arm inserts in the carriage, and by the locking of the locking framework below the side arm, flexibly connect by bearing pin between key seat relative with described side arm and the light echo box, tracheae places the light echo box; Have positioning hole on the hole wall of described mesopore, positioning screwn passes this hole and links to each other with cylindrical shell; Described cylindrical shell is the duplex pull rod structure, pull bar and three layers of housing form three cavitys, the top of pull bar links to each other with handle, the piston of bottom installing is close to the inner housing inwall, inner housing upper end and the stifle bolt between pull bar and inner housing, the lower end has the single acting piston valve to be close to the middle shell inwall, the outer wall of connecting head and frame and middle shell bolt, the one-way valve plug is equipped with in the lower end of middle shell, is bolted with back-up ring between the inner and outer shell of cylindrical shell upper end;

Described locking framework constitutes jointly by the spring in the hole of described side arm below, ball and with concave arc on the position limit pin that ball cooperates; The valve of described tracheae is concatenated into one by valve made in U.S.A and valve made in Great Britain by screw thread, and the Camlock mouth of calming the anger links to each other with the frame of valve made in Great Britain by bearing pin; The metal insert that is spirally connected with the pull bar upper end is housed in the inside groove of described handle, and this handle is made by elastic material.

The utility model adopts the support of inflator with the carriage flexible connection of saddle the recessive type inflator can be complementary with any saddle and need not special-purpose saddle; The light echo box that links to each other with support both can play the light echo reflection, can be used for placing tracheae again, need not specially dispose the container of exhaust tube; The cylindrical shell of inflator adopts combined type duplex pull rod structure, and inflator pressure is increased, and fast aeration is used laborsaving; The structure of valve has strengthened its versatility.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the utility model sectional view;

Fig. 2 is the plan view of the utility model support;

Fig. 3 is the plan view of the utility model support.

As shown in the figure, the utility model comprises handle 4, cylindrical shell 5 and the tracheae 7 that is connected with the frame of cylindrical shell 5, the upper end of its cylindrical shell 5 is enclosed within the mesopore 23 of support 2, support cylindrical shell by this mesopore 23, the side arm 21 of support 2 is hinged with the carriage 1 of saddle below by bearing pin 8 simultaneously, the through hole 24 that position limit pin 3 runs through on the side arm 21 inserts in the carriage 1, the restriction saddle can not move, this position limit pin 3 is by locking framework 9 lockings of side arm 21 belows, and described locking framework 9 is by the spring 31 in the hole 33 of described side arm 21 belows, ball 232 and constitute jointly with concave arc on the position limit pin 3 that ball 232 cooperates.Flexibly connect by bearing pin 10 between key seat 22 relative and the light echo box 6 with described side arm 21, when tracheae 7 does not use, place light echo box 6, have positioning hole on the hole wall of described mesopore 23, positioning screwn 36 passes this hole and links to each other with cylindrical shell 5, prevents to make the saddle displacement because of support 2 rotates.Described cylindrical shell 5 is the duplex pull rod structure, be pull bar 51 with cylindrical shell 5 in, in, outer three layers of housing form A, B, three cavitys of C, metal insert 41 bolts of being adorned in the inside groove of the top of pull bar 51 and handle 4, the piston 511 of bottom installing is close to inner housing 52 inwalls, inner housing 52 upper ends and stifle 11 bolts between inner housing 52 and pull bar 51, the lower end has single acting piston valve 521 to be close to middle shell 53 inwalls, there are connecting head 12 and frame 54 and middle shell 53 bolts in the upper end in B chamber, one-way valve 531 is equipped with in the lower end of middle shell 53, is bolted with back-up ring 13 between the inner and outer shell of cylindrical shell 5 upper ends.The valve of described tracheae 7 is concatenated into one by valve made in U.S.A 71 and valve made in Great Britain 72 by screw thread, and the Camlock mouth 720 of calming the anger links to each other with the frame of valve 72 made in Great Britain by bearing pin 721.Described handle 4 is made by elastic material.

In the time of need inflating, position limit pin 3 is moved down, make carriage 1 be with saddle about turning on the bearing pin 8, expose handle 4, tracheae 7 is taken out in light echo box 6, and valve is aimed at tire, during pulling handle 4, at first extract pull bar 51 out, when the piston 511 for the treatment of its bottom is pumped down to stifle 11 places of top, A chamber, relies on the resistance of stifle to drive inner housing 52 and rise, thereby realize compound bitubular body duplex pull rod structure, when pressing down, air-flow enters the C chamber from the single acting piston valve 521 of inner housing lower end and the one-way valve 531 of middle shell lower end, and through being connected the tracheae 7 input tires on the frame 54, it is big to reach pressure, inflation is rapid, the labour-saving effect.Inflate and finish, turn down saddle, the locking position limit pin, this moment, handle played the effect of vibration damper.
