Description

Middle rod device of anti-pinch umbrella

Technical Field

The utility model relates to a well stick device especially relates to a well stick device of preventing pressing from both sides umbrella.

Background

Referring to fig. 1 and 2, a conventional umbrella extension adjusting device 2 (refer to taiwan patent document TW M470554U), the conventional umbrella extension adjusting device 2 is adapted to a middle rod 1 of an umbrella, the central rod 1 comprises an upper branch pipe 11 and a lower branch pipe 12 which is hollow and is used for accommodating the upper branch pipe 11, the conventional umbrella extension adjusting device 2 comprises a base 21 for the upper branch pipe 11 to pass through, a locking nut 22 for the upper branch pipe 11 to pass through and lock with the corresponding base 21, and a clamping module 23 disposed on the base 21, the base 21 has an outer opening 211 for the clamping module 23 to pass through, the lower leg 12 has an inner opening 122 corresponding to the outer opening 211, the clamping module 23 has a block 231 and a handle 232 mounted on the base 21 and connected to the block 231.

However, when the pad 231 passes through the outer opening 211 and the inner opening 122 and is pressed against the surface of the upper branch pipe 11, accidents such as pinching hands or mistakenly pinching other objects may occur.

In addition, most of the existing umbrella telescopic adjusting devices are that the large and small circular tubes are sleeved with each other, but when the umbrella is opened and closed, the large and small circular tubes are easy to rotate relatively, and one of the large and small circular tubes causes difficulty in folding the umbrella cover. Secondly, when the umbrella is opened, the clamping part in the small circular tube can not be clamped in the inner hole matched with the large circular tube every time due to the rotation between the large circular tube and the small circular tube, which is quite inconvenient. In order to solve the disadvantages of the round tube, some manufacturers process the large and small round tubes into a small special-shaped tube and a large special-shaped tube with a diameter matched with the small special-shaped tube, and the rotation between the large and small special-shaped tubes is limited by the shape of the special-shaped tube, so as to improve the problem of the rotation of the middle rod when opening and closing the umbrella. However, the number of processes required for manufacturing the special pipe is increased compared to that for manufacturing the circular pipe, which means that the cost is increased, and the structural strength of the middle rod itself is damaged after the special pipe is deformed by machining, so that the existing technology has a room to be improved.
