Abstract
The utility model relates to the technical field of umbrellas, in particular to a middle rod structure of a multi-fold pull rope type automatic umbrella. The middle rod is hollow and is formed by mutually sleeving a plurality of sections of pipe bodies, a compression spring for opening the umbrella is arranged in the middle rod, a positioning column is sleeved in an inner middle hole of the compression spring, one end of the positioning column is fixedly connected to a fixed seat of the middle rod, and the positioning column is a telescopic pipe body. When the umbrella is opened, the positioning column automatically extends to guide and position the compression spring of the opened umbrella, so that when the umbrella is folded, the compression spring in the middle rod is effectively guided and limited, no deflection occurs, and the smooth folding of the umbrella is ensured.
Description
Technical field:
The utility model relates to the parachute kit technical field, refers in particular to bar structure among the automatic umbrella of a kind of many folding dragline types.
Background technology:
Parachute kit is as the daily living article of people's sun-shading rain-proof, and, practical characteristics light because of it is subjected to people's favor deeply.Occurred on the market recently a kind ofly forming the collapsible automatic umbrella of driving mechanism by pulley and stay cord, it not only has automatic opening function, and uses more conveniently, thereby has also won market gradually.Wherein, the driving mechanism that pulley and stay cord are formed is arranged on the middle rod, during one end of stay cord is connected on the holder of excellent lower end, and the other end run through in the rod in the compression spring and reference column among the hole, and be connected in down on the nest behind the rod in passing via the pulley winding of middle rod upper end, cause open parachute kit and in making rod will descend up pull-up of nest by stay cord when stretching out, make down and move on the nest and realize the parachute-opening purpose.Yet, the automatic umbrella of this class at present, wherein the compression spring that is provided with in the rod is longer, run through rod in whole, and middle rod is made up of the mutual socket of many foldings body, thereby the endoporus of middle rod is increasing successively.Current, the external diameter of compression spring only is complementary with the aperture of middle excellent minimal segment body, thereby have than big gap between compression spring and other inner hole wall than big body, upward only be provided with a bit of reference column in maximum body section guides the compression spring to existing simultaneously middle rod.When closing one's umbrella, beat bending phenomenon is arranged when being positioned at the compression spring of large aperture body, not only influence compression spring oneself shrinks, but also the reference column movable end is often arranged and compress the mutual blocking case of spring, causes and can't close one's umbrella.
Summary of the invention:
The purpose of this utility model is to overcome the defective of prior art, provides a kind of simple in structure, bar structure among the automatic umbrella of folding stay cords more than parachute kit closes one's umbrella smoothly.
For achieving the above object, the utility model is achieved through the following technical solutions: the reference column in the middle rod is a telescopic body, it is made up of the plurality of sections body, the mutual sheathed connection of each section body, and in reference column, be provided with the compression spring that driving respective activity body stretches out; The contracted length of reference column and the contracted length of middle rod are complementary.
Reference column of the present utility model is telescopic body, thereby it extends the compression spring of guiding and locating parachute-opening automatically when parachute-opening, and when consequently closing one's umbrella, the compression spring in the middle rod is effectively led and be spacing, and beat does not take place, and it is smooth and easy to guarantee to close one's umbrella.
Description of drawings:
Accompanying drawing 1 is the utility model combining structure schematic diagram;
Accompanying drawing 4 is the utility model embodiment schematic diagram.
The specific embodiment:
See accompanying drawing 1～4, rod 1, pulley 4 and stay cord 5 during the utility model includes, in excellent 1 hollow, and form by the mutual socket of multistage body, be provided with the compression spring 2 that parachute-opening is used in the middle rod 1, the interior mesopore of compression spring 2 is arranged with a reference column 3, during an end of reference column 3 is fixed on the holder 11 of excellent 1 upper end.Reference column 3 is a telescopic body, and it is made up of the plurality of sections body, the mutual sheathed connection of each section body, and in reference column 3, be provided with the compression spring 31 that driving respective activity body stretches out, the contracted length of reference column 3 and middle excellent 1 contracted length are complementary.
During parachute-opening, press the parachute-opening button and remove snap close, then in the rod 1 the compression spring 2 of pressurized open and in promoting excellent 1 upper end and upper nest body 6 move, middle rod 1 each section body extends outward, the stiff end of the connection handle of rod 1 during the stiff end system of stay cord 5 is connected to, the other end up spurs lower honeycomb body 7 by pulley 4, and fulcra 8 launch in driving when moving on the lower honeycomb body 7, interior fulcra 8 drive other umbrella frame and launch in succession, realize parachute-opening.When middle excellent 1 each section body stretches, reference column 3 also unmuzzles thereupon, compression spring 31 in it ejects other movable body of reference column 3, other overhanging portion of the compression spring 2 of parachute-opening is guided and located to realization lengthening reference column 3, so that when closing one's umbrella subsequently, the beat bending takes place in the compression spring 2 at excellent 1 epimere position in the deduction and exemption, and it is smooth and easy to guarantee to close one's umbrella.Wherein when closing one's umbrella, when protuberance touches the overhanging end of reference column 3 within central excellent 1 lower end, i.e. the projecting tube of compression set post 3 and make its withdrawal automatically is complementary until the contracted length and middle excellent 1 the contracted length of reference column 3, promptly finishes closing one's umbrella.
