Abstract

The utility model discloses a middle rod structure of a full-automatic opening and closing umbrella. The middle rod structure comprises a middle rod. The middle rod is composed of at least three tubes and comprises an outer tube, a middle tube and an inner tube. The outer tube, the middle tube and the inner tube are connected together in a sleeved mode in sequence. The middle tube comprises a tube expanding portion. An inner sleeve is arranged in the tube expanding portion. Because the inner sleeve is additionally arranged in the tube expanding portion of the middle tube, an umbrella opening spring makes contact with the inner sleeve firstly when the umbrella opening spring is controlled to open and close the umbrella. Consequently, contact between the umbrella opening spring and the inner wall of the middle rod is reduced, and the sounds made in the process of opening and closing the umbrella and noise are lowered. The strength through which the middle rod fastens the whole full-automatic opening and closing umbrella is below 45 newtons.

Description

The middle bar structure of full-automatic opening and closing umbrella

Technical field

The utility model relates to a kind of full-automatic opening and closing umbrella, particularly relates to a kind of middle bar structure of full-automatic opening and closing umbrella.

Background technology

Umbrella, as people's a kind of sunshade used in everyday or rainproof instrument, is a kind of product indispensable during people live, and in recent years, because of climate change impermanence, makes everyone all have the custom of carrying umbrella with it, soaked through to prevent that precipitate heavy rain from being drenched into.But early stage umbrella need up be pushed into certain position by umbrella frame with hand and umbrella can be strutted, once anxious lower often the having little time of brash, umbrella is strutted just and drenched.Therefore, someone just designs a kind of umbrella, be provided with a button in grip, pressing this button can automatically open umbrella and not have automatic umbrella-collecting function, in the time that wish is ridden, still needing that both hands use together could be into the car by umbrella folding, drench and still subject to rainwater within this blink, so just lose the convenience of umbrella itself.Therefore on market, develop a kind of automatic umbrella folding and unfolding.The operating principle of this automatic umbrella folding and unfolding is: in the time that wish is opened umbrella, press button downwards, make the control of umbrella shaft device out of hand, the deployment spring of umbrella shaft inside releases energy, and umbrella shaft is upspringed and stretched, and umbrella is opened; And in the time that wish is packed up umbrella, again press button, make the also control of device out of hand of discount in umbrella shaft, discount is release conditions, under the elastic force effect of the umbrella colsing spring on umbrella frame, make umbrella cover be umbrella closing state, discount is withdrawn into umbrella shaft top by stay cord; Now, also in incomplete umbrella closing state, reach completely and close one's umbrella, also will exert oneself again umbrella cover part to promote to grip, umbrella shaft is shortened, deployment spring is put aside energy again, and umbrella shaft and discount are subject to the control device control in lever again, and parachute kit is just folding state completely like this.

But owing to being provided with deployment spring in umbrella shaft inside, in the time opening while closing one's umbrella due to the contraction of spring and shrink, to make to open the sound that closes one's umbrella large with the collision of middle excellent inwall, quietly easily causing noise, is unfavorable for use.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of middle bar structure of full-automatic opening and closing umbrella, can full-automatic opening and closing umbrella opening while closing one's umbrella action, lower and open the sound closing one's umbrella, reduce noise pollution.

For solving the problems of the technologies described above, the middle bar structure of a kind of full-automatic opening and closing umbrella that the utility model provides, comprise middle rod, described middle rod is at least made up of three broken pipes, comprise outer tube, middle pipe and inner tube, described outer tube, middle pipe and inner tube connect together successively, and described middle pipe comprises expansion tube department, in described expansion tube department, is provided with inner sleeve.

Preferably, described inner sleeve is that plastic-steel material is made.

Preferably, in described middle rod, be provided with deployment spring, described deployment spring runs through the middle rod of expansion.

Preferably, the internal diameter of described inner sleeve is greater than the external diameter of described deployment spring.

The utility model is set up inner sleeve in the expansion tube department of described middle pipe, open in the process closing one's umbrella at described control deployment spring, deployment spring is contacted with described inner sleeve at first, thereby reduce contacting of deployment spring and middle excellent inwall, reduce to open the sound that closes one's umbrella, reduce noise, and the strength that whole umbrella fastened middle rod completely by the utility model full-automatic opening and closing umbrella is below 45 newton.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

As Figure 1-4, for the middle bar structure of the utility model full-automatic opening and closing umbrella, comprise middle rod, described middle rod is at least made up of three broken pipes, deployment spring 6 is arranged in described middle rod, run through the middle rod of expansion, described middle rod comprises outer tube 1, middle pipe 2 and inner tube 3, be that outer tube 1, middle pipe 2 and inner tube 3 connect together successively, described outer tube 1 upper end is connected with upper nest 4, lower end is provided with outer tube bank mouth 11, in described outer tube 1, is also provided with boosting spring 7, and the diameter of described boosting spring 7 is greater than the diameter of described deployment spring 6; Described middle pipe 2 comprises expansion tube department 21 and middle tube bank mouth 22, described expansion tube department 21 is formed on the end of described middle pipe 2, described expansion tube department 21 is movably set in described outer tube 1, described outer tube bank mouth 11 is for preventing described expansion tube department 21 slippages, the external diameter of described expansion tube department 21 equals the internal diameter of described outer tube 1, in described expansion tube department 21, is provided with inner sleeve 23, and described inner tube 3 movable upper ends are set in described middle pipe 2, lower end is connected with described handle 5, and described middle tube bank mouth 22 is for preventing described inner tube 3 slippages.The internal diameter of described inner sleeve 23 is greater than the external diameter of described deployment spring 6, described inner sleeve 23 is made for POM material (plastic-steel material), the described outer mouth 11 of restraining is 8-12mm with the length of described middle tube bank mouth 22, and described outer tube bank mouth 11 is regular hexagon, and described middle tube bank mouth 22 is column type.

The middle bar structure of the utility model full-automatic opening and closing umbrella is set up inner sleeve 23 in the expansion tube department 21 of described middle pipe 2, open in the process closing one's umbrella at described control deployment spring 6, deployment spring 6 is contacted with described inner sleeve 23 at first, thereby reduce contacting of deployment spring 6 and middle excellent inwall, reduce to open the sound that closes one's umbrella, reduce noise, and the strength that whole umbrella fastened middle rod completely by the utility model full-automatic opening and closing umbrella is below 45 newton.

By specific embodiment, the utility model is had been described in detail above, but these not form restriction of the present utility model.In the situation that not departing from the utility model principle, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection domain of the present utility model.
