[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings. Example 1

[0027] This embodiment mainly describes the umbrella connector, as follows:

[0028] like Figures 1 to 6As shown, the umbrella connecting piece includes a fixed sleeve 45 and a rotating sleeve 4. The fixed sleeve 45 is fixed to the seat frame 1. The rotating sleeve 4 is rotatably connected to the fixed sleeve 45 and is used to connect with the umbrella frame 2, so that the umbrella is fixed to the seat frame 1 through the rotating sleeve 4 and the positioning sleeve 3. A gear 5 is slidingly provided between the positioning sleeve 3 and the rotating sleeve 4. A first gear ring 31 meshing with the gear 5 is provided on the inner wall of the positioning sleeve 3, and a second gear ring 41 meshing with the gear 5 is provided on the inner wall of the rotating sleeve 4. A push button 6 extending from the outside to the inside of the rotating sleeve 4 and abutting against the gear 5 is slidably provided on the rotating sleeve 4. The push button 6 is used to push the gear 5 to slide, so as to adjust the gear 5 to disengage from the second gear ring 41 and release the meshing of the gear 5 with the second gear ring 41. A return spring 7 is provided in the positioning sleeve 3, one end of the return spring 7 abuts against the inner wall of the positioning sleeve 3, and the other end abuts against the gear 5. The return spring 7 is used to provide a rebound force for the gear 5 so that the gear When the push button 6 is pressed by an external force, the gear 5 is pushed by the push button 6 to slide into the positioning sleeve 3. When the gear 5 is disengaged from the second gear ring 41, the rotating sleeve 4 and the positioning sleeve 3 can rotate relative to each other. When the push button 6 loses force, the gear 5 is pushed by the elastic force of the return spring 7 and slides toward the rotating sleeve 4 to return to its initial state. At this time, the gear 5 is meshed with the first inner gear ring and the second inner gear ring at the same time, and the rotating sleeve 4 is in a locked state. At this time, the rotating sleeve 4 cannot be rotated. The above-mentioned loss of force refers to the situation where the push button 6 is not pressed by an external force. In this solution, when pressing the push button 6 to drive the gear 5 to slide, it is only necessary to overcome the gravity of the push button 6, the friction between the gear 5 and the rotating sleeve and the positioning sleeve, and the elastic force of the spring, and the gravity of the push button 6 is relatively small. Compared with the existing technology, the present invention is more labor-saving.

[0029] like Figure 2 、 Figure 3 and Figure 5 As shown, a connecting shaft 33 is provided in the positioning sleeve 3, and the axis center line of the connecting shaft 33 coincides with the axis center line of the positioning sleeve 3. The gear 5 and the reset spring 7 are sleeved on the connecting shaft 33. An axial hole 34 is provided on the axis center of the connecting shaft 33 to pass through the connecting shaft 33. A connecting hole 43 is provided on the rotating sleeve 4 to cooperate with the axial hole 34. The connecting shaft 33 passes through the axial hole 34 and the connecting hole 43 in turn to rotate the rotating sleeve 4 and connect it to the positioning sleeve 3. The setting of the connecting shaft 33 plays a guiding role to avoid the reset spring 7 from being misplaced due to uneven force when it is compressed and slides along the connecting shaft 33, resulting in failure of the reset spring 7.

[0030] Specifically, the length of the tube wall of the positioning sleeve 3 is greater than or equal to the length of the gear 5. In order to reduce the size of the umbrella connector for easy carrying, it is preferably that the length of the tube wall of the positioning sleeve 3 is equal to the length of the gear 5. The gear 5 has a concave installation space 52 on the side close to the return spring 7. An annular mounting seat 53 is provided in the installation space 52. The end of the return spring 7 that abuts against the gear 5 is sleeved on the annular mounting seat 53. The setting of the installation space 52 can reduce the space for installing the return spring 7. When the gear 5 is pushed by the push button 6 to slide into the positioning sleeve 3 until the gear 5 disengages from the rotating sleeve 4, the gear 5 slides completely into the positioning sleeve 3. At this time, the return spring 7 is compressed and has an elastic force on the annular mounting seat 53.

[0031] like Figure 6 As shown, a mounting hole 51 for the connecting shaft 33 to pass through is provided at the center of the gear 5. In order to prevent the gear 5 from rubbing against the connecting shaft 33 during sliding, the diameter of the mounting hole 51 is larger than the diameter of the connecting shaft 33. The axis of the annular mounting seat 53 is colinear with the center of the mounting hole 51, so that the elastic force of the reset spring 7 acts on the center of the rotating sleeve 4, thereby enhancing the stability of the gear 5 during reverse sliding.

[0032] like Figures 3 to 5 Therefore, the push button 6 has a retaining ring 61 extending toward the edge at one end close to the gear 5, and a blocking step 44 is provided on the inner wall of the rotating sleeve 4. The retaining ring 61 is restricted in the rotating sleeve 4 by the blocking step 44. The setting of the retaining ring 61 and the blocking step 44 can prevent the push button 6 from slipping out and disengaging from the rotating sleeve 4.

[0033] like Figure 4 and Figure 5 As shown, the end of the positioning sleeve 3 away from the rotating sleeve 4 is provided with a clamping hoop 9 clamped on the seat frame 1, and the clamping hoop 9 includes a left half clamping hoop 91 and a right half clamping hoop 92. Corresponding fixing holes 93 are provided on both sides of the left half clamping hoop 91 and the right half clamping hoop 92. The left half clamping hoop 91 and the right half clamping hoop 92 are fixed by bolts passing through the fixing holes 93 of the left half clamping hoop 91 and the right half clamping hoop 92 and cooperating with nuts. When in use, the nuts are rotated outward to adjust The distance between the left half clamp 91 and the right half clamp 92 is put on the seat frame 1, and the positioning sleeve 3 can be fixed to the seat frame 1 by tightening the nut. Through the cooperation of the left half clamp 91, the right half clamp 92 and the bolts and nuts, the positioning sleeve 3 can be adapted to seat frames 1 with different pipe diameters. The rotating sleeve 4 has a fixing sleeve 45 fixed to the umbrella. The handle of the umbrella is inserted into the fixing sleeve 45 and fixed to the fixing sleeve 45. The angle of the umbrella can be adjusted by adjusting the angle of the rotating sleeve 4. Example 2

[0034] This embodiment mainly describes a chair with an umbrella connector, as follows:

[0035] like Figure 3 As shown, it includes a seat, and the above-mentioned umbrella connector is fixed on the seat frame 1 of the seat. The umbrella connector can connect the umbrella to the seat frame 1, and the angle of the umbrella can be adjusted by adjusting the rotating sleeve 4 of the umbrella connector.

[0036] The umbrella connector is not only used on seats, but can also be used on any object that needs to be equipped with an umbrella or a parasol.

[0037] When in use, pressing the push button 6 drives the gear 5 to slide into the positioning sleeve 3 until the gear 5 disengages from the second gear ring 41, the return spring 7 is compressed, and the rotating sleeve 4 is in an unlocked state. At this time, the rotating sleeve 4 can be rotated to adjust the umbrella to a desired angle. When the push button 6 loses its power, the gear 5 is no longer pushed by the push button 6. Under the action of the return spring 7, the gear 5 slides into the rotating sleeve 4 and simultaneously engages with the positioning sleeve 3 and the rotating sleeve 4 to lock the rotating sleeve 4. At this time, the rotating sleeve 4 is in a locked state and cannot be rotated.

[0038] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the product of the present invention is usually placed when in use.
