CN2322442Y - Middle rod structure for multi-section umbrella - Google Patents

Abstract

The utility model discloses a middle rod structure for a multi-section umbrella, mainly composed of an inner section pipe (1), an outer section pipe (2), and a group of clip position devices (7) which are composed of springs (71), plug bodies (72), a stopping posts (73), wherein, the contour of a stopping edge (722) at the rear section of each plug body (72) forms a butting and stopping shape, and the stopping edge (722) is plugged in the lowest section of the inner section pipe. A stopping post (731) is coniform, and the stopping post (731) can bulges from a through hole (15) of the inner section pipe and can flex. The inner section pipe is extended into the outer section pipe (2). Since a long guide slot (12) of the inner section pipe and a long guide slot (23) of the outer section pipe are matched, the inner section pipe and the outer section pipe can be effectively extended and fixed under the action of the clip position devices (7) and under the condition of the fact that the inner section pipe and the outer section pipe can not rotate. Meanwhile, the umbrella is put up and disassembled with smooth feeling.

Description

The novel middle bar structure of multi-section umbrella

The utility model relates to daily class, particularly a kind of novel middle bar structure of multi-section umbrella.

As everyone knows, bar structure is shown in accompanying drawing 1, accompanying drawing 2 among the multi-section umbrella commonly used, it is mainly cooperated to be inserted in the outer segment tube (2p) by an outer segment tube (2p) and an inner segment tube (1p) and forms, and then is its central axis not at same straight line by be provided with the outstanding hole (11p) of two lug-latches at this internal segment tube wall; Other is provided with a tool two positioning pilot holes (31p) and is corresponding to the lug-latch positioning seat (3p) of the outstanding position, hole (11p) of above-mentioned two lug-latches and is inserted in the inner segment tube (1p), each has been inserted in spring (51p) respectively in regular turn and has stretched and has connect lug-latch (5p), spring (41p) and outstanding lug-latch (4p) in each positioning pilot hole (31p), makes outstanding lug-latch (4p) and stretch to connect lug-latch (5p) and eject outside the outstanding hole (11p) of the lug-latch of inner segment tube (1p); This outer segment tube ancient piece of jade, round, flat and with a hole in its centre is provided with and stretches out hole (21p) and receiving part (22p), be the position of giving prominence to hole (11p) and positioning pilot hole (31p) simultaneously corresponding to each lug-latch, after inner segment tube (1p) stretches, just make to stretch and connect lug-latch (5p) and block receiving part (22p), at this moment outstanding lug-latch (4p) is also given prominence to and is finished middle excellent extension and fix by the hole (21p) of stretching out of outer segment tube (2p) simultaneously, with the use that can open an umbrella.

But with regard to the multi-section umbrella that said structure is formed, for being provided, inner segment tube (1p) is located in outer segment tube (2p) inside in engage sleeves, and make inner segment tube (1p) be able to doing definitely effectively to uphold fixing with outer segment tube (2p), to reach the effect that can open an umbrella and use, remove to want must be earlier to locate axially to establish elongated guide groove (23p) and locate at the receiving part (22p) of outer segment tube (2p) on along it, and cooperate the outstanding hole (11p) of the set lug-latch that is corresponding cooperation with the receiving part (22p) of outer segment tube (2p) and is provided with of inner segment tube (1p) to locate, become the elongated guide groove (12p) that axially also is provided with the identical radian measure size, so that after inner segment tube (1p) is being placed in outer segment tube (2p) inside, get this two elongateds guide groove (23p) of mat, cooperatively interacting (12p), make inner segment tube (1p) and outer segment tube (2p) do in the extension process, be unlikely the phenomenon that rotates between the two, and then make inner segment tube (1p) again in being placed on outer segment tube (2p) do extension fixation procedure, especially will be again in the inside of inner segment tube (1p), go the sheathed one lug-latch positioning seat (3p) that has two positioning pilot holes (31p) on it again, and must in this two positioning pilot hole (31p), divide sheathed spring (41p) and outstanding lug-latch (4p), one spring (51p) and stretch the structure that connects lug-latch (5p) and be provided with down, can make outstanding lug-latch (4p) and stretch and connect outside the outstanding hole (11p) of lug-latch that lug-latch (5p) ejects inner segment tube (1p), make in its elongated guide groove (12p) of inner segment tube (1p) mat and cooperate in elongated guide groove (23p) the slippage drawing process of outer segment tube (2p), be unlikely under generation rotates between the two mutually, and then make again to stretch and connect lug-latch (5p) and block receiving part (22p), at this moment, outstanding lug-latch (4p) is also given prominence to fastening by the hole (21p) of stretching out of outer segment tube (2p) simultaneously, the extension of rod is fixed in can realizing, reaches the multi-section type result of use that opens an umbrella.But it is especially complicated that its whole implementation structure seems, and seem suitable numerous and diverse in assembling especially, and increase many troubles and inconvenience on foot.

The purpose of this utility model is exactly the shortcoming that exists at bar structure among the above-mentioned common multi-section umbrella, and bar structure in a kind of multi-section umbrella novel is provided, make between inner segment tube and outer segment tube and can under the unlikely situation that rotates, do effectively to uphold to fix, and the suitable sense of preferable cunning is arranged in support reduction, umbrella.

The technical solution of the utility model:

The utility model mainly is made up of an inner segment tube, an outer segment tube and one group of screens device, in section of the end of elongated guide groove and for longitudinal center is equipped with cracking of suitable length, and up is provided with a perforation with the Cheng Jiushi degree parallactic angle of cracking at inner segment tube; In addition include a spring, cock body and a bumping post and formed, make between inner segment tube and outer segment tube and can under the unlikely situation that rotates, do effectively to uphold to fix, play support, the effect of the umbrella that contracts by one group of screens device; Cock body is by the plastic cement material integrated injection molding, can realize producing in batches reducing cost, and inner segment tube is done to stretch or during the withdrawal action, the retaining edge profile of this cock body back segment can and the outer segment tube inwall between the suitable sense of preferable cunning is arranged.
