Abstract

The utility model relates to a positioning device for a lower plate head of an umbrella, which comprises a fixed lower plate A and a movable lower plate B, wherein, a cam groove (1) is arranged on the fixed lower plate A, and a cam (2) is arranged in the cam groove (1). The movable lower plate B is a regulating handle with an antiskid groove (3), and the regulating handle and the cam (2) are tightly fixed into a whole. Transition sections (4) with different radiuses are arranged on the cam (2). The utility model breaks the traditional structure of positioning the lower plate head by using a springing way, and overcomes the trouble of milling a flute on an umbrella bar. Thus, the strength of the umbrella bar is enhanced.

Description

The positioner of coiled hair under the en-toutcas

The utility model is the improvement invention about coiled hair positioner under the en-toutcas.

In the prior art, the following coiled hair location of en-toutcas is adopted spring usually, this spring location at first must groove milling on the umbrella bar, spring is contained in the groove milling, if in process, if spring support shelves often are difficult to descend the coiled hair location too short, as the mesopore of coiled hair of blowing down breaks away from spring and will make that umbrella cover is improper to be closed up, and influence is used.Occur a kind of Extension Spring-type en-toutcas on the current market, its primary structure is between every umbrella frame and following coiled hair extension spring to be housed, though avoided spring and the groove milling of umbrella bar, because every umbrella frame all has the dress extension spring, not only cost improves, and technology is cumbersome.

In view of the problem that known technology exists, the purpose of this utility model is to design and provides a kind of and both need not bounce also without coiled hair positioner under the en-toutcas of extension spring, and this device is not only simple in structure, and easy to use.

The utility model is finished as follows, the positioner of coiled hair includes quiet lower wall and moving lower wall under the en-toutcas, has cam path on the described quiet lower wall, cam is installed in the cam path, described moving lower wall has the regulating handle of anti-slip tank, this regulating handle and cam are fixed as one, the transition that has radius unequal on the cam, when opening the umbrella use, to descend coiled hair up to shift the position onto, its umbrella cover is opened, with being about to regulating handle with anti-slip tank to angle of anticlockwise, because increasing, the effect frictional force of cam transition just can maintain open configuration to umbrella cover, when umbrella need close up, only need be with regulating handle to angle of right rotation, the cam transition changes the relevant position, frictional force reduces, and following coiled hair moves down umbrella cover automatically and closes up.

The utility model is compared with prior art: have simple in structure, easy to operate, both reduced cost, increase umbrella bar intensity again, the location is reliable.

The utility model has following accompanying drawing

Fig. 1 is a structural representation of the present utility model

Fig. 2 is a cam structure schematic diagram of the present utility model

Accompanying drawing has been represented structure of the present utility model and embodiment, further describe each relevant details of embodiment below more in conjunction with the accompanying drawings, with regard to en-toutcas, include umbrella cover, umbrella bar; umbrella handle; long bone; short bone; folder horse; go up coiled hair and following coiled hair and integral product of spring positioner formation; what the application's case related to is to belong to the improvement invention of coiled hair positioner down; it is characterized in that following coiled hair is divided into quiet lower wall A and moving lower wall B; be provided with cam path (1) on quiet lower wall A; cam (2) is installed in the cam path (1); described moving lower wall B is the operating grip with anti-slip tank (3); this operating grip and cam (2) are fixing also can be in positive and negative 15 ° of scope left-right rotation; have the transition of radius unequal on the cam (2); its thickness distance is between 0.5mm～1.6mm; because thickness utilizes the degree of tightness friction to reach the purpose of location apart from not waiting during rotary handle.Following coiled hair can form with the ABS plastic pressure injection, press the positioner of coiled hair under the en-toutcas of the utility model design motif made, applicable to the umbrella cover location of any type of en-toutcas, be the breakthrough improvement of tradition spring location, will bring positive result of use.

Claims

1, a kind of following coiled hair positioner of en-toutcas, include quiet lower wall A and moving lower wall B, it is characterized in that described quiet lower wall A is provided with cam path (1), be installed in the described moving lower wall B of cam (2) in the described cam path (1) and be one and have the regulating handle of impartial anti-slip tank (3).

2, coiled hair positioner down as claimed in claim 1 is characterized in that having transition (4) on the cam (2).

3, down coiled hair positioner as claimed in claim 1 or 2, the distance of transition (4) that it is characterized in that cam (2) is between 0.5 millimeter～0.6 millimeter.
