Description

Technical Field

[0001] The utility model relates to the technical field of outdoor products, and particularly relates to a new umbrella honeycomb. Background Art

[0002] An umbrella is a commonly used rain and sunshade tool in life. The umbrella ribs of an umbrella usually have a honeycomb structure, in which the upper honeycomb is fixed at the top of the umbrella rod, and the lower honeycomb moves up and down along the middle rod. When moving upward, the umbrella is opened, and when moving downward, the umbrella is closed. In order to keep the state of the umbrella fixed when it is opened, a honeycomb switch is provided on the upper honeycomb and the lower honeycomb.

[0003] The existing umbrella honeycomb switches are mainly push-pull switches. The upper honeycomb and the lower honeycomb are in concave-convex fit through openings and limiting parts, and the clutch is controlled by pushing and pulling, so as to complete the opening or closing of the umbrella. In this concave-convex fit mode, the cooperation often fails, resulting in difficulty in opening the umbrella. And after long-term use, the material wears, reducing the buckling points, and the elastic force decreases due to material aging. Moreover, the cooperation between the upper honeycomb and the lower honeycomb is not stable, and the lower honeycomb is easy to shake when the umbrella is unfolded, affecting the use experience of the umbrella. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a new umbrella honeycomb to solve the above problems.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A new umbrella honeycomb includes an umbrella rod, an upper honeycomb and a lower honeycomb. The upper honeycomb is fixedly arranged at the top end of the umbrella rod. The lower honeycomb includes a sliding tube, sliding balls and a control sleeve. The sliding tube is slidably sleeved on the umbrella rod and is located below the upper honeycomb. The tube wall of the sliding tube is provided with ball holes penetrating through the tube wall in the circumferential direction. The sliding balls are movably placed in the ball holes. The side wall of the umbrella rod is provided with a locking groove for the bottom ends of the sliding balls to be inserted into. The control sleeve is movably sleeved on the sliding tube and is used for driving the sliding balls to be inserted into or disengaged from the locking groove.

[0007] Preferably, the inner wall of the control sleeve is provided with multiple levels of annular step parts, and the inner diameter sizes of the steps of the multiple levels of annular step parts increase sequentially from top to bottom. The depth of the ball holes is less than the diameter of the sliding balls. A support ring is arranged at the bottom end of the sliding tube. The support ring is elastically connected with the multiple levels of annular step parts through a spring to push the multiple levels of annular step parts to slide upward, and the sliding balls are pressed into the locking groove through the side wall of the lowermost level step.

[0008] Preferably, the control sleeve includes an upper tube portion and a lower tube portion from top to bottom, and the inner diameter of the upper tube portion is larger than that of the lower tube portion. The ball hole is located on the lower tube portion. The umbrella rod includes an upper umbrella rod, a middle umbrella rod, and a lower umbrella rod from top to bottom. The outer rod diameter of the upper umbrella rod is fitted and matched with the inner diameter of the upper tube portion. The outer rod diameter of the lower umbrella rod is fitted and matched with the inner diameter of the lower tube portion. There are gaps between the outer rod wall of the middle umbrella rod and the inner tube walls of the upper tube portion and the lower tube portion. The locking groove is located on the middle umbrella rod. The multi-stage annular stepped portion is a three-level step. When the sliding ball is located in the locking groove, the top of the sliding ball contacts the side wall of the bottommost level step. When the sliding ball rolls on the rod wall of the middle umbrella rod, the top of the sliding ball contacts the side wall of the middle level step. When the sliding ball rolls on the rod wall of the lower umbrella rod, the top of the sliding ball contacts the side wall of the topmost level step.

[0009] Preferably, a first slope portion is provided at the connection of adjacent two sets of steps of the multi-stage annular stepped portion, and a second slope portion is provided at the connection of adjacent two sets of the upper umbrella rod, the middle umbrella rod, and the lower umbrella rod.

[0010] Preferably, an upper limit ring is provided on the outer wall of the umbrella rod and above the control sleeve. The outer diameter of the limit ring is larger than the inner diameter of the control sleeve. A lower limit ring is provided on the inner tube wall of the control sleeve and below the multi-stage annular stepped portion. The inner diameter of the lower limit ring is smaller than the outer diameter of the support ring.

[0011] Preferably, an unlocking pressure ring is provided on the outer tube wall of the control sleeve.

[0012] Preferably, there are four sets of the sliding ball, the ball hole, and the locking groove that are mutually adapted.

[0013] Preferably, a lower serrated portion is provided at the bottom end of the upper honeycomb, and an upper serrated portion that meshes with the lower serrated portion is provided at the top end of the lower honeycomb.

[0014] Preferably, the locking groove adopts an arc-shaped groove.

[0015] After adopting the above technical solution, compared with the background technology, the present invention has the following advantages:

[0016] The utility model provides a novel umbrella honeycomb. A ball hole is arranged on the sliding tube of the lower honeycomb and a slidable ball that can move up and down is placed therein. When the lower honeycomb slides up to the umbrella unfolding position, the control sleeve pushes the ball downwards to be stuck into the locking groove on the rod wall of the umbrella rod, thereby locking the lower honeycomb. Since the slidable balls are arranged circumferentially along the sliding tube, they cooperate and support to limit between the umbrella rod and the sliding tube from all directions, preventing the lower honeycomb from swaying left and right, improving the stability and firmness of the whole umbrella frame. When unlocking, the control sleeve is also used to drive the slidable balls to disengage from the locking groove and slide in contact with the rod wall of the umbrella rod, ensuring the stability of the umbrella frame during folding. The structure is simply installed and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
