Description

The location structure of baggage car telescopic lever handle

The utility model relates to a kind of registration device of baggage car telescopic lever handle, especially refer to that a kind of pull bar that only need press down just can push controll block and move backward, utilize return spring to eject controll block again, make the blocking bar support location structure into the baggage car telescopic lever handle in the handle body slotted eye.

Baggage car telescopic lever handle is a kind of dilatory structure of baggage car that makes things convenient for, when walking, can conveniently draw row, yet do not attain perfect design owing to structurally exist, step is complicated when implementing assembling, price is high, and is also not very convenient in the operation, so develop a kind of location new construction of baggage car telescopic lever handle, with the shortcoming that overcomes assembling and use, be the consistent dreamboat of pursuing of relevant manufacturer.

Main purpose of the present utility model is to provide a kind of location structure of baggage car telescopic lever handle, and it can make snap-fastener, drawing piece and the cover plate of location structure easy, fast speed is assembled on the upper bracket seat.

Secondary objective of the present utility model is to provide a kind of location structure of baggage car telescopic lever handle, reaching quick location and stretching pull bar, and save time, the labour-saving effect.

For this reason, the utility model is taked following technical scheme:

A kind of location structure of baggage car telescopic lever handle, it is characterized in that comprising that one is located at the telescopic lever group that the handle body both sides are become by the mutual insert group of inner and outer pipe respectively, with the members such as pull bar location structure of device in the upper bracket seat, described pull bar location structure is made up of a snap-fastener, a controll block, a return spring, a cover plate and screw element, described snap-fastener bottom design becomes a prominent tenon with back guiding incline, the combination back just and the set inclined-plane of cutting of controll block be in contact with one another; Described controll block central authorities establish a jack, the jack trailing edge establish one with snap-fastener after the corresponding inclined-plane of cutting of guiding incline, reach and to push the coordinated control of slippage backward by snap-fastener, and establish a hole radially in its back, for the assembling return spring, and at its front projection one blocking bar, for stretch out positioning tie bar the slotted eye that inserts handle body from the perforation of upper bracket seat; Described cover plate is a rectangular plate, by screw and the sealed one of upper bracket seat room.

By above-mentioned member, a kind of location structure of baggage car telescopic lever handle can be provided, press down snap-fastener and push the inclined-plane of cutting of controll block, and make controll block move backward with the back guiding incline, recess outside the slotted eye of handle body up to its fwd blocking bar, pull bar so can stretch; In addition, just can push controll block toward reach, relend and help the elastic-restoring force of return spring to eject controll block, and make the blocking bar support positioning tie bar in the slotted eye of handle body again toward pressing down pull bar.Its assembling easily, and is easy to use, with low cost.

The utility model one preferred embodiment is described with reference to the accompanying drawings as follows:

Fig. 1 is a spatial structure decomposing schematic representation of the present utility model.

Fig. 2 is a three-dimensional combination scheme drawing of the present utility model.

Fig. 3 is an assembled sectional view of the present utility model.

Fig. 4 is a usage operation scheme drawing of the present utility model ().

Fig. 5 is a usage operation scheme drawing of the present utility model (two).

Fig. 6 is a usage operation scheme drawing of the present utility model (three).

The figure number explanation:

10 telescopic lever groups, 11 handle body, 111 slotted eyes, 12 interior pipes, 13 outer tubes, 14 upper bracket seats, 141 rooms, 142 perforation, 143 open-works, 20 pull bar location structures, 21 snap-fasteners, 211 back guiding inclines, 212 prominent tenons, 22 controll blocks, 221 jacks, 222 cut the inclined-plane, 223 holes, 224 blocking tenons, 23 return springs, 24 cover plates, 25 screws.

Please cooperate and consult Fig. 1 to shown in Figure 3, the utility model embodiment includes one and is located at handle body 11 both sides, respectively telescopic lever group 10 and the members such as pull bar location structure 20 of device in upper bracket seat 14 that is become by inner and

outer pipe

12,13 mutual insert groups.Wherein a recessed slotted eye 111 is offered in handle body 11 central sides, is the perforation 142 to kissing upper bracket seat 14; Above-mentioned upper bracket seat 14 middle parts are provided with prominent hollow out room 141, for assembling pull bar location structure 20, offer perforation 142 in its side, the blocking bar 224 that can pass through slotting controll block 22 is in the slotted eye 111 of handle body 11, end face is established and is stayed an open-work 143, with the prominent snap-fastener 21 of establishing; Above-mentioned pull bar location structure 20 comprises elements such as a snap-fastener 21, a controll block 22, a return spring 23, a cover plate 24 and screw 25, and snap-fastener 21 bottom design become a prominent tenon 212 with back guiding incline 211, just and the controll block 22 set inclined-planes 222 of cutting be in contact with one another transmission; Above-mentioned controll block 22 central authorities establish a jack 221, jack 221 trailing edges then establish one with the guiding inclines 211 corresponding inclined-planes 222 of cutting, snap-fastener 21 back, reach the coordinated control of pushing slippage backward with snap-fastener 21, and establish a hole 223 radially in its back, to put return spring 23, and at its front projection blocking bar 224, for positioning tie bar the slotted eye 111 that reaches handle body 11 from the perforation 142 of upper bracket seat 14; Above-mentioned return spring 23 is one to have the coil spring body of retractility, is seated in the hole 223 of controll block 22; Above-mentioned cover plate 24 is rectangular plates, by screw 25 and upper bracket seat 14 rooms 141 sealed one.

By the combination of above-mentioned member, and obtain the location structure of the utility model baggage car telescopic lever handle, it manipulates situation and operating principle is as described below:

See also shown in Figure 4ly, press down snap-fastener 21 with finger, by guiding incline 211 thereafter push draw piece 22 cut inclined-plane 222, and make controll block 22 move backward, cause its fwd blocking bar 224 to be recessed outside the slotted eye 111 of handle body 11, the pull bar that so can stretch is as Fig. 5, shown in Figure 6.

Then, only need can push controll block 22 toward reach toward pressing down pull bar, the elastic force of storing up return spring 23 then ejects controll block 22, makes blocking bar 224 support positioning tie bar in the slotted eye 111 of handle body 11.

In sum, the utility model simple structure, combination is easy, and can reach the easy to operate expection effect of use, and it is practical, and creative.
