Description

Technical Field

[0001] The utility model belongs to the technical field of hanging umbrella parts and relates to a handrail shell of a hanging umbrella. Background Art

[0002] The sunshade umbrella is a large parasol used to block direct sunlight. Since it was originally designed to shade the courtyards of nobles, it is also called a courtyard umbrella. The armrest shell is an important part of the sunshade umbrella. The armrest shell is set on the column of the umbrella and can be moved up and down for adjustment. The armrest shell is often equipped with a crank to control the internal wire wheel to rotate the retracting wire to control the opening and closing of the umbrella body, and the armrest shell also has the function of locking the height of the umbrella.

[0003] The patent with authorization announcement number CN214016353U discloses a spiral locking structure of an armrest shell of a parasol, wherein the parasol includes a vertical pole and an armrest shell mounted on the vertical pole, and the spiral locking structure includes a locking piece and a handle, wherein the locking piece is threadedly connected to a threaded hole provided on the armrest shell, and the handle is used for transmission installation with the locking piece, and the handle can rotate relative to the armrest shell and drive the locking piece to rotate, and when the locking piece rotates on the threaded hole, it can move toward the vertical pole and press against the vertical pole.

[0004] The above-mentioned armrest shell structure can be locked with the column, but there are still some shortcomings: the locking piece is directly pressed against the column by cooperating with the threaded hole, but when the umbrella with a larger area is affected by wind and shakes the column, it may directly rub the locking piece and cause deflection, which eventually causes the top pressure of the locking piece to decrease and the armrest shell to slip, and the locking is not stable enough. Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art and provides an armrest shell of a hanging umbrella. The technical problem to be solved by the utility model is that the locking structure of the prior armrest shell is unstable.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A handrail shell for a hanging umbrella, comprising a shell and a handwheel rotatable relative to the shell, wherein the shell has a vertically penetrating column hole, and is characterized in that the outer side of the shell has a horizontally arranged annular boss, the handwheel is threadedly matched with the outer peripheral surface of the annular boss or the inner edge surface of the annular boss and can be fed along the axial direction of the handwheel, and the annular boss has a push rod axially arranged along the annular boss, one end of the push rod is located in the column hole, and the other end of the push rod is axially fixed to the handwheel and can rotate relative to the handwheel.

[0008] The shell of the handrail shell is installed on the column of the hanging umbrella, and the column is inserted in the hole of the column. The shell can be adjusted up and down relative to the column to change the height of the umbrella body of the hanging umbrella; by arranging a horizontally arranged annular boss on the outer side of the shell, the hand wheel is threadedly connected to the annular boss so as to feed axially when the hand wheel is rotated, and a push rod is arranged in the annular boss, so that one end of the push rod extends into the hole of the column and the other end is axially fixed on the hand wheel. In this way, when the hand wheel rotates, the hand wheel can feed relative to the annular boss and thus drive the push rod to move, so that one end of the push rod can be pressed toward the outer periphery of the column in the horizontal direction, thereby realizing the locking of the shell and the column, and when the umbrella body is driven by wind to shake the column and act on the push rod, the push rod can be directly rotated relative to the hand wheel if it is deflected, and the torque will not cause the hand wheel to reverse, which is beneficial to ensure the stability of the handwheel locking position and avoid the reduction of the push pressure of the push rod on the column, thereby improving the locking stability.

[0009] In the armrest shell of the above-mentioned hanging umbrella, the inner hole of the annular boss is in the shape of a square hole, and the push rod is circumferentially positioned in the inner hole of the annular boss. In this way, the push rod can only slide along the inner hole of the annular boss, which is conducive to further reducing the amount and probability of deflection of the push rod, thereby effectively preventing the hand wheel from rotating due to the reaction of the push rod, and improving the locking stability.

[0010] In the armrest shell of the above-mentioned hanging umbrella, the end of the push rod located in the hole of the column has a pressing surface, and the pressing surface is in the shape of a concave arc surface. This is conducive to the pressing surface and the surface of the column to form a fit, increase the effective area to improve the static friction during locking, and at the same time, the column and the pressing surface can cooperate to further restrict the deflection of the push rod and improve the locking stability.

[0011] In the above-mentioned handrail shell of the hanging umbrella, the shell is in the shape of a vertical plate, and a handle is arranged in the vertical direction on one side of the horizontal direction of the shell, and the annular boss is located on the side of the shell. Such a handle is convenient for the user to apply force to control the shell to adjust up and down along the column, and it is also convenient for the user to hold the position of the shell with one hand and directly turn the hand wheel located on the side of the shell with the other hand, which conforms to the user's operating habits and improves convenience. At the same time, the area on both sides of the shell does not need to be provided with existing components such as wire wheels, which can ensure that the side of the column away from the top pressure rod can obtain a larger area of ​​support from the inner wall of the column hole, thereby ensuring structural strength and locking stability.

[0012] In the above-mentioned handrail shell of the hanging umbrella, the hand wheel comprises a cylindrical screw connection part and an annular gripping part arranged around the outer periphery of the screw connection part, the screw connection part is screwed and sleeved on the outer peripheral surface of the annular boss, and a plurality of plate-shaped connecting parts arranged at intervals around the screw connection part are provided between the inner edge of the gripping part and the outer peripheral surface of the screw connection part. In this way, the user can control the rotation of the entire hand wheel by operating the gripping part with a larger outer diameter, which is more labor-saving and convenient to operate, and the connecting part is conducive to ensuring the connection strength between the gripping part and the screw connection part, and ensuring the stability of the structure.

[0013] In the above-mentioned handrail shell of the hanging umbrella, the two inner walls of the column hole along the axial direction of the pressing rod are provided with staggered reinforcing ribs, which is conducive to increasing the structural strength of the two sides of the shell, so that the shell will not be deformed and fail due to the pressing force during the locking process between the column and the shell.
