Description

Technical Field

[0001] This utility model relates to the field of umbrellas, and in particular to a quick-release umbrella fixing base. Background Technology

[0002] An umbrella is a tool that provides shade or shelter from rain, snow, and sun. People usually hold the umbrella handle with their hand; however, in some situations, it's impossible to free one hand to hold the handle, such as when pushing a wheelchair or riding a bicycle. To address this issue, some researchers have implemented a method of fixing the umbrella handle to eliminate the need for manual gripping. For example, Chinese patent application number CN202121701462.8 describes a fixable umbrella handle, including a handle body with a first connector integrated into the handle body at its lower part; a second connector is detachably connected below the first connector. The connector includes a second connector with an integrally formed fixing base below it. An upper locking seat is detachably connected to the fixing base. Multiple vertical connecting tubes are connected to the upper locking seat. The vertical connecting tubes pass through the fixing base and connect to a first nut. The upper surface of the upper locking seat abuts against the lower part of the fixing base. A lower locking seat is detachably connected below the upper locking seat. The lower locking seat is connected to the upper locking seat via a first locking bolt. The bottom end of the first locking bolt passes through the lower and upper locking seats and is threadedly connected to the vertical connecting tubes. This utility model allows the umbrella handle to be fixed to a cylindrical handlebar via the upper and lower locking seats, thus freeing up the hands.

[0003] The aforementioned umbrella handle has the following improvements: the original umbrella handle and the fixing seat were designed as a single piece, which required removing several bolts to remove the umbrella from the handlebars, which was very inconvenient. In addition, after removal, there was still a rather large fixing seat under the umbrella handle, which was not convenient for daily use.

[0004] Therefore, a quick-release umbrella holder that can detach from the umbrella handle is needed. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model proposes a quick-release umbrella holder that solves the problems of cumbersome umbrella handle installation and inconvenience for daily use after the handle is removed in the prior art.

[0006] The technical solution is as follows: A quick-release umbrella holder includes a columnar holder with a mounting hole coaxially opened at the top of the holder. The holder also includes a locking part, a clamping part, and a fixing part arranged sequentially from the opening of the mounting hole to the bottom of the holder. The locking part prevents the umbrella handle from coming out of the mounting hole, the clamping part clamps the umbrella handle, and the fixing part allows the holder to be fixed to the columnar object.

[0007] The locking part includes a first blind hole that is evenly opened on the inner wall of the mounting hole perpendicular to the axis of the mounting hole. A spring pin protruding perpendicularly to the axis of the mounting hole is provided in the first blind hole. When the umbrella handle is inserted, the umbrella handle causes the spring pin to retract into the first blind hole. After the umbrella handle is inserted, the spring pin rebounds so that the umbrella handle cannot be pulled out. The fixing base is also provided with an unlocking mechanism that can release the locked state of the umbrella handle.

[0008] The clamping part includes a rotating ring coaxially and movably sleeved on the outside of the fixed base, and a number of push plates arranged on the inner side of the mounting hole. A push mechanism is provided on the side of the push plate away from the axis of the mounting hole. The rotating ring rotates to one side, which enables the push mechanism to push the push plate towards the center, thereby clamping the umbrella handle with the push plates.

[0009] Furthermore, a flange protruding perpendicularly to the axis of the first blind hole is provided at the opening of the first blind hole. When the spring pin is in the pop-out state, part of it is located inside the first blind hole and part of it protrudes out of the first blind hole. The spring pin is provided with a protrusion protruding outward perpendicular to the axis. The protrusion and the flange cooperate to prevent the spring pin from popping out of the first blind hole.

[0010] Furthermore, the unlocking mechanism includes an unlocking collar coaxially sleeved on the fixed base. The unlocking collar includes an outer wall and an inner wall. The outer wall is coaxially sleeved outside the outer wall of the fixed base, and the inner wall is coaxially movably inserted into the mounting hole. The top ends of the outer wall and the inner wall are fixedly connected. The unlocking collar can move up and down about the axis of the mounting hole or rotate about it. Moving the unlocking collar downwards can push the spring pin back into the first blind hole, thereby allowing the umbrella handle to be removed.

[0011] Furthermore, the outer wall of the collar is provided with a guide groove parallel to the axis of the mounting hole. At both ends of the guide groove, transverse slots are respectively provided in a direction perpendicular to the guide groove. The outer wall of the fixing seat is provided with a guide pin. The guide pin is disposed in the guide groove. The guide groove and the guide pin cooperate to allow the unlocking collar to move up and down along the direction of the guide groove. When the guide pin moves relative to the transverse slot, it can rotate the unlocking collar, move the guide pin relative to the transverse slot, and prevent the unlocking collar from moving up and down.

[0012] Furthermore, the fixed base has several through slots perpendicular to the axis of the mounting hole. The pushing mechanism includes a movable rod and a driven rod. The movable surfaces of the movable rod, the driven rod, and the rotating ring are coplanar and all perpendicular to the axis of the mounting hole. One end of the movable rod passes through the through slot and is rotatably connected to the rotating ring. One end of the driven rod is rotatably connected to the inner wall of the mounting hole. The middle parts of the movable rod and the driven rod are movably connected to each other. After the rotating ring rotates about one side of the axis of the mounting hole, it can drive the movable rod to move, so that the other ends of the movable rod and the driven rod are relatively close to the axis of the mounting hole, so that the pushing plate can be pressed towards the axis of the mounting hole.

[0013] Furthermore, a ratchet groove is provided on the outer wall of the fixed base, and the surface where the ratchet groove is located is perpendicular to the axis of the mounting hole. A second blind hole is provided on the side of the rotating ring near the fixed base. The axis of the second blind hole is perpendicular to the axis of the mounting hole, and the opening faces the fixed base. A spring block that can translate along the axis of the second blind hole is movably embedded in the second blind hole. A spring is provided between the spring block and the end face of the second blind hole so that the spring block can abut against the ratchet groove. The cooperation between the spring block and the ratchet groove makes the rotating ring rotate only to one side.

[0014] Furthermore, a pull rod is coaxially fixed to the end of the spring block away from the fixed base. The pull rod protrudes outward through the rotating ring and is connected to a pull ring. Pulling the pull ring will pull the spring block back to the second blind hole, allowing the rotating ring to rotate in the opposite direction.

[0015] Furthermore, the push plate is divided into two parts, namely plate one and plate two. Plate one is rotatably connected to the end of the movable rod away from the rotating ring, and the rotating surface of plate one is coplanar with the movable surface of the movable rod. Plate two is rotatably connected to the end of the driven rod away from the inner wall of the mounting hole, and the rotating surface of plate two is coplanar with the movable surface of the driven rod. Plate two is movably embedded in plate one. The push plate has a clearance groove so that plate two can move in the clearance groove. The moving direction of plate two is perpendicular to the axis of the mounting hole.

[0016] Furthermore, a tension spring is provided between the second plate and the end face of the relief groove, and the tension spring pulls the second plate toward the end face of the relief groove.

[0017] Furthermore, the fixing part includes clamp one and clamp two. The middle part of clamp one is fixedly connected to the fixing base, and the surface of clamp one is perpendicular to the bottom surface of the fixing base. One end of clamp two is rotatably connected to one end of clamp one, and the rotating surface is coplanar with the surface of clamp one. The other end of clamp two is provided with a rotatably connected bolt, and the rotating surface of the bolt is coplanar with the rotating surface of clamp two. The other end of clamp one is provided with a groove, which can be used to insert the bolt into the groove and screw the nut onto the bolt. By tightening the bolt, clamp one and clamp two can be closed to clamp the columnar object between them to achieve the purpose of fixing.

[0018] This utility model has the following advantages: By setting a clamping part that can be clamped and released, the umbrella handle is fixed. A locking part is also provided in the mounting hole. The locking part can automatically lock the umbrella handle after it is inserted, preventing it from being pulled out, thus further fixing the umbrella handle. An unlocking mechanism is also provided for the locking part, which can unlock the locking mechanism, allowing the umbrella handle to be removed freely. When the umbrella needs to be removed, simply loosen the clamping part and use the unlocking mechanism to contact the lock of the locking part to remove the umbrella handle. There is no need to remove the fixing base fixed in one place, saving the trouble of installation. The umbrella is also convenient for daily use after it is removed. In addition, the clamping part can adapt to umbrella handles of different sizes. Attached Figure Description
