Background technique

The traditional parasol structure usually adjusts the inclination angle of the canopy by means of a bending device provided in the umbrella, so that the umbrella can be adjusted to be shaded by the maneuverability, and is suitable for outdoor sunshade. However, the existing bending device can only adjust the inclination angle of the canopy, and cannot adjust the rotation of 360° with respect to the ground level. Therefore, as the angle of the sun changes, it is necessary to transfer the base of the umbrella by hand. The angle can be adjusted to better the shade of the sun, so it is quite inconvenient to use.

The rotating device of the curved joint of the umbrella with the utility model disclosed in Chinese Patent No. 01123034X is a rotating device for adjusting the circumferential rotation angle of the umbrella surface and the ground at a horizontal angle of 360 degrees, which is arranged in the support tube of the umbrella. Between the upper support tube and the lower support tube, the outer casing, the fork rod female joint, the § wheel set, the internal gear, the fork rod male joint, the spring, the meshing ring, the rotating body, and the shaft tube that can be rotated and tested, And the positioning tube and the rotating tube are formed, the top end and the bottom end of the outer casing form an inner circular arc, and the inner circular arc surface is provided with a clamping groove, and the inner circular arc is sleeved on the top end of the lower supporting tube, and the winding rod of the first handle is pivoted In the outer casing; a plurality of claw pieces are arranged upward on the circumference of the cylinder of the fork rod female joint. The 360° sunshade adjustment of the canopy is achieved by rotating the related components by rotating the body. However, the device has structural defects such as structural complexity and inconvenient assembly. Summary of the invention

Referring specifically to FIG. 1 and FIG. 2, the rotating device of the rotatable canopy of the present invention is mainly composed of a knob 9, a bearing housing 4, a coupling shaft 2, a sleeve 10, a clutch ring A8, a clutch ring B7, a spring 5, and the like. Composition, where:

The knob 9 has a hollow cylindrical shape, and an upper portion has an annular flange for engaging with the outer casing 13 of the rocker mechanism 12, and the knob 9 and the outer casing 13 are provided with a certain space for the knob to move. The knob 9 has a plurality of steps therein, and the bearing seat 4, the sleeve 10, the spring 5 and the like are mounted therein, wherein the upper inner wall of the knob 9 has an internal thread matched with the retaining ring 3, and the lower inner wall has a clutch ring and a B tooth 81, respectively. The meshing segmented internal teeth 93, 91 have an inner ring groove 92 between the two teeth, so that the knob 9 can be pulled down, so that the clutch ring A8 is at the inner ring groove 92, and the clutching ring A8 and the knob 9 are separated. , to turn the knob 9.

The coupling shaft 2 is a shaft type member for connecting the sleeve 10 and the bearing housing 4, and has a step 21 for the gear position at the front end and a screw hole for fixing the sleeve 10 at the lower portion.

The bearing housing 4 is sleeved on the upper part of the coupling shaft 2, and the upper part of the shaft hole has a shoulder for matching with the coupling shaft to prevent shaking. The lower portion is provided with a bearing 6, and the side wall is machined with a screw hole connected to the clutch ring B71. The sleeve 10 is sleeved on the lower portion of the coupling shaft 2, and is provided with a screw hole for fixing the clutch ring A81 and a screw hole for fixing the coupling shaft 2.

The clutch ring A81 and the clutch ring B71 are gears of different shapes and shapes of the two i-bases, and teeth ^, 71 which mesh with the teeth 93, 91 of the inner wall of the knob are respectively provided at the periphery of the ring. On the two rings 81, 71, the 剐3⁄4 has a hole in which the sleeve 10 and the bearing housing 4 are connected. In order to smoothly realize the clutching between the clutch ring A8 and the knob 9, the upper end edge 94 of the inner wall of the knob and the lower end edge 82 of the clutch ring A are processed into a slope.

When assembling, the bearing housing 4 is first inserted into the coupling shaft 2, the bearing 6 is mounted on the lower part of the bearing housing 4, and then the sleeve 10 is inserted, and then the sleeve 10 and the coupling shaft 2 are fixed together by screws, thereby forming a Next, first insert the retaining ring 3 on the middle section 1, then insert the upper part coupling shaft 2 with the bearing housing 4 into the middle section 1, and then insert the spring 5 and the clutch ring B7 on the middle section 1, and then The clutch ring B7, the middle section 1 and the bearing block 4 are fixed together by screws; in addition, the lower part coupling shaft 2 with the sleeve 10 is inserted into the adjusting tube 11, and the tube 11 is sheathed into the clutch ring A8, and then The clutch ring A8, the adjusting tube 11 and the sleeve 10 are fixed together by screws; the rod is integrally connected with the middle section 1 and the adjusting tube 11, and then inserted into the knob 9, and the internal teeth 93, 91 in the knob are respectively coupled with the clutch The teeth 81, 71 on the rings VIII and B are engaged, and the retaining ring 3 is screwed into the thread groove of the knob 9, and the elastic strength of the spring 5 is adjusted by adjusting the distance between the retaining ring 3 and the knob 9. Elastic, thus adjusting the appropriate degree of cooperation between the knob 9 and the clutch ring, B, so that the knob 9 is positioned in the corresponding section of the middle section Position, the upper end of the crank knob 9 then the placement of the sound and the housing 13 to 12 cows ₉

In addition to the adjustment of the umbrella angle of the umbrella, the utility model can also use the utility model to adjust the 360° rotation of the umbrella surface. When in use, hold the knob 9 by hand and press down to disengage the clutch ring A81 from the internal tooth 93 of the knob, and the spring 5 is compressed when the word is changed (from the state of Fig. 1 to the state of Fig. 2, the state of Fig. 3 changes to Fig. 4). Status). At this time, the knob 9 can be rotated, and the clutch ring B71 is rotated by the knob 9. Since the clutch ring B71 is fixed with the middle section 1 and the bearing housing 4, the middle section 1, the clutch ring B71 and the bearing housing 4 can be rotated together. The rotation of the middle section 1 can also drive the umbrella surface ^]. At the same time, the rotation of the bearing housing 4 will drive the rotation of the bearing 6, but will not drive the rotation of the coupling shaft 2, because the coupling shaft 2 of the bearing housing 4 is empty and sleeved, so the rotation of the coupling shaft 2 will not drive the shaft. Set of 10 and below parts, the 3⁄4 turn of this 1 will not slam the parts below the adjustment tube 11. When the adjustment is completed, the gripping operation of the hand S can be relaxed, and the knob 9 can rebound upward by the elastic force of the spring 5, so that the teeth 93 on the clutch ring and the teeth on the clutch ring A81 are again meshed and positioned, ready for the next operation. .

The above is a preferred embodiment of the present invention, but in addition to the structure shown in the drawings of the embodiment, the present invention may have other structural modifications without departing from the scope of the present invention. As described above, the clutch mechanism and the connecting mechanism can be combined with the form of the teeth shown in the figure, and can also be combined with the groove and the groove, and can also achieve the disengagement between the lower tube and the knob and the upper tube. Connection to the knob.
