Abstract

The utility model relates to an improved structure of a stick of a multi-section umbrella, composed of an inner tube (1), an outer tube (2), and an elastic V-shaped blocking and stopping device (6). The utility model is characterized in that the inner tube (1) and the outer tube (2) are provided with axial long guiding slots used for positioning, and an elastic V-shaped positioning block is arranged between the inner tube (1) and the outer tube (2). A top section of the long guiding slot of the outer tube (2) is provided with the upper section of the blocking and connecting part of the outer tube (2) to made a guiding slot having a smaller radian, and a guiding slot having a bigger radian is made at the bottom segment of the blocking and connecting part of the outer tube (2). The long guiding slot in the outer tube (1) is made, and the long type guiding slot has same radian as that of the long guiding slot of the upper segment of the self blocking and connecting part of the outer tube (2). A blocking and connecting part is directly arranged from the bottom section of the long guiding slot of the inner tube (1) to the outer part of the long guiding slot of the inner tube (1). The utility model has the advantages of simple structure, and easy assemblage.

Description

Bar structure improvement among the multi-section umbrella

The utility model relates to the structure of the parachute kit that uses in the daily life, particularly relates to the improvement of bar structure among the multi-section umbrella.

As everyone knows, the parachute kit of people's use is diversified in daily life, pattern difference not only, its structure is also different, have folding, have flexible, also has more piece, the utility model relates to the improvement of bar structure among a kind of multi-section umbrella, as shown in Figures 1 and 2, it includes interior pipe (1) and outer tube (2), and the centre utilizes a positioning seat (3) as connecting align member, and cooperates two groups of positions in two stop blocks (4) of Different Plane and (5) and in conjunction with spring (41) and (51) and interior pipe (1) and outer tube (2) tabling.This kind structure on the implementation, rather complicated, assemble more loaded down with trivial details, again since its two stop block (4) and (5) and spring (41) and (51) install, add the setting of the guide groove of interior pipe (1) and outer tube (2), the convenient requirement that then makes this multi-section umbrella not meet manufacturing, use.

Main purpose of the present utility model is the deficiency at bar structure among the above-mentioned multi-section umbrella, provide a kind of simple in structure, assembling be easy in bar structure, and pipe and outer tube are effectively upheld the effect of location in can guaranteeing.

The technical solution of the utility model:

The utility model it be by one the structure exquisiteness the V-arrangement stopper, pipe inner bottom periphery in it is sheathed on, be to establish a positioning block by a flexure strip and one pleurapophysis to be formed, and its V-arrangement stopper is sheathed on interior pipe inner bottom periphery, and then be located in the outer tube when doing to uphold the location at interior pipe box, and eject in set the stretching out the hole and reach and uphold fixing purpose of outer tube top section periphery relative position.

Structure of accompanying drawings the utility model and embodiment:

Fig. 1 is a bar structure perspective exploded view among the common multi-section umbrella.

Fig. 2 is a bar structure combination generalized section among the common multi-section umbrella.

Fig. 3 is the structural upright decomposing schematic representation of the utility model.

Fig. 4 is the textural association generalized section of the utility model.

Fig. 5 is in the structure of the utility model, the schematic perspective view of elasticity V-arrangement stopper.

(1) for interior pipe, (2) be outer tube, (3) for positioning seat, (4) and (5) be that V-arrangement stopper, (61) be locating piece for the less elongated guide groove of outer tube radian, (23 ") for the big elongated guide groove of outer tube radian, (6) for outer tube elongated guide groove, (23 ') for outer tube receiving part, (23) for stretching out hole, (22) for interior pipe receiving part, (21) for interior pipe range type guide groove, (13) for outstanding hole, (12) for spring, (11) for stop block, (41) and (51).

Attached 4, accompanying drawing 5 explanation structure of the present utility model and embodiment in conjunction with the accompanying drawings 3:

The utility model is made of an interior pipe (1), outer tube (2) and elasticity V-arrangement stopper (6).At the elongated guide groove (23) that is axially arranged with of outer tube (2), and, stretch out hole (21) and on its top section periphery, be provided with in the top of elongated guide groove (23) section peripheral hardware one receiving part (22).

Be inserted in pipe (1) in from outer tube (2) bottom, the elongated guide groove (12) that is axially arranged with along interior pipe (1), and cooperate with the axial set elongated guide groove of outer tube (2) (23), and establish an outstanding hole (11) at its end section periphery and the set position, hole (21) of stretching out of outer tube (2) top section periphery, again elasticity V-arrangement stopper (6) is sheathed on interior pipe (1) inner bottom periphery, and the dash forward locating piece (61) established of one side can be done outstanding being positioned in interior pipe (1) the end section set outstanding hole of periphery (11). this reality has novel another characteristics namely to be receiving part (22) epimere that establish in the section place, elongated guide groove (23) top of outer tube (2); Be to change system into the littler elongated guide groove (23 ') of radian (shown in the A place generalized section of accompanying drawing 3); And its end Duan Ze makes the bigger elongated guide groove of radian (23 ") (shown in the B place generalized section of accompanying drawing 3); And cooperation will be managed the elongated guide groove (12) of (1) within outer tube (2) bottom is nested with; Then make and the radian identical (as the C place generalized section of accompanying drawing 3 shown in) of outer tube (2) from receiving part (22) epimere elongated guide groove (23); And and directly from elongated guide groove (12) end section of inner tube (1) to peripheral hardware one receiving part (13); And then the while engage sleeves is located at the elastic V shaped stopper (6) of inner tube (1) inner bottom periphery; The dash forward locating piece (61) established of one side is done outstanding set the stretching out in the hole (21) of outer tube (2) top section that be positioned; Can make inner tube (1) and outer tube (2) not rotate between the two in the situation, reach the effect of upholding the location.

The utility model is simple in structure, assembling is easy, and under the situation that interior pipe and outer tube do not rotate, do effectively to uphold to fix, and reaches the effect of the use that can open an umbrella.
