[0026] The technical scheme of the utility model will be further described below in combination with the drawings of the specification:

[0027] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 A telescopic windproof sunshade umbrella includes a stand 1, an umbrella frame 2, a support column 3, a sliding rod 4 connected slidingly in the stand 1, a lower umbrella disc 7 connected slidingly outside the stand 1, a middle umbrella disc 6 fixed to the top of the stand 1, an upper umbrella disc 5 fixed to the top of the sliding rod 4, and a limiting sliding block 9. The sliding rod 4 is inserted into the stand 1 and slides in the stand 1. The top of the sliding rod 4 extends outside the stand 1, and the bottom of the sliding rod 4 is located inside the stand 1. The upper umbrella disc 5 is sleeved on the top end of the sliding rod 4, and the middle umbrella disc 6 and the lower umbrella disc 7 are sleeved outside the stand 1. The middle umbrella disc 6 and the lower umbrella disc 7 can slide up and down along the stand 1 or the sliding rod 4. The limiting sliding block 9 is sleeved on the bottom of the sliding rod 4 and is used to keep the sliding rod 4 axially consistent with the stand 1 and prevent excessive displacement. The contact surface 93 of the limiting sliding block 9 and the sliding rod 4 is provided with multiple inclined guide surfaces 91 on both sides, which has a good limiting and guiding effect.

[0028] The sliding rod 4 is square, the middle umbrella disc 6 has a square hole 61 corresponding to the sliding rod 4, the stand 1 is cylindrical, and the lower umbrella disc 7 has a circular hole 73 corresponding to the stand 1. When the umbrella is opened or closed, the circular hole 73 facilitates the sliding of the middle umbrella disc 6 up and down along the sliding rod 4 and the sliding of the lower umbrella disc 7 up and down along the stand 1, and the sliding is more smooth. The square hole 61 can prevent the entire umbrella frame 2 from rotating. The inner wall of the sliding sleeve 71 is provided with vertical stripes 74, which are used to reduce the machining precision of the sliding sleeve 71, so that it can closely fit the stand 1 without increasing the friction, facilitating people to open or close the umbrella, and making the use more stable.

[0029] The square hole 61 also includes a first square hole for sealing and a second square hole for keeping axial consistency.

[0030] The upper umbrella disc 5 is provided with an end cover 8 for sealing. The top of the sliding rod 4 is connected and fixed with the upper umbrella disc 5. The end cover 8 is sleeved on the upper umbrella disc 5 and the top of the sliding rod 4. The length of the sliding rod 4 is less than the length of the stand 1. The hinge point of the long support rod 32 and the umbrella frame 2 is located below the middle part of the umbrella frame 2, that is, the hinge point of the long support rod and the umbrella frame exceeds the middle part of the umbrella frame. This design can make the force of the umbrella frame more uniform and the windproof ability stronger.

[0031] The middle umbrella plate 6 and the lower umbrella plate 7 are slidably connected to the upright column 1. The upper umbrella plate 5, the middle umbrella plate 6, and the upper umbrella plate 7 are distributed sequentially from top to bottom. One side of the umbrella frame 2 is hinged to the upper umbrella plate 5. The middle umbrella plate 6 and the lower umbrella plate 7 are both hinged to the other side of the umbrella frame 2 through the support column 3. The hinge point of the middle umbrella plate 6 to the umbrella frame 2 through the support column 3 is located above the hinge point of the lower umbrella plate 7 to the umbrella frame 2 through the support column 3. Therefore, there are three hinge points between the upper umbrella plate 5, the middle umbrella plate 6, and the lower umbrella plate 7 and the umbrella frame 2. Among them, the two hinge points of the middle umbrella plate 6 and the lower umbrella plate 7 are the stress points. By distributing the stress through the middle umbrella plate 6, the pressure on the limiting pin can be greatly reduced, thereby preventing deformation and extending the service life. The sliding rod and the upright column are double-layer support rods, which greatly improves the stability. They will not deform or deform even in strong winds and have a long service life. This utility model can control the opening or closing of the umbrella frame 2 by controlling the up and down movement of the lower umbrella plate 7 and the extension and retraction of the sliding rod 4.

[0032] The support column 3 includes several long support rods 32 and several short support rods 31. The lower umbrella plate 7 is hinged to the umbrella frame 2 via the long support rods 32. The long support rods 32 and short support rods are hinged to the umbrella frame 2 at intervals. The middle umbrella plate 6 is hinged to the umbrella frame 2 via the short support rods 31. The number of short support rods 31 is half the number of long support rods 32. The support column 3 has a large number of support rods, and the long and short support rods are arranged in a crisscross pattern, which can evenly transfer the weight of the umbrella frame and external forces to the support column 1, thereby greatly increasing stability and significantly enhancing the resistance to deformation.

[0033] The bottom of the lower umbrella tray 7 is fitted with a sliding sleeve 71. A control button 72 is provided on the sliding sleeve 71. The control button 72 has a limit pin 721 corresponding to the limit hole and a spring 722 that controls the limit pin to remain locked. Therefore, the control button 72 is used to control the locking and unlocking between the lower umbrella tray 7 and the upright 1. Pressing the control button locks the lower umbrella tray 7 and the upright 1; pressing the control button again unlocks the umbrella tray 7 and the upright 1. There are two limit holes, located at the top and bottom of the upright, corresponding to the open or closed state of the umbrella frame.

[0034] When the umbrella frame 2 is opened or closed, the middle umbrella plate 6 remains relatively fixed, the upper umbrella plate 5 and the lower umbrella plate 7 move closer together as the umbrella frame 2 is opened, and move further apart as the umbrella frame 2 is closed; the sliding rod 4 shortens as the umbrella frame 2 is opened, and extends as the umbrella frame 2 is closed.

[0035] Working principle:

[0036] By controlling the up-and-down movement of the lower umbrella disc and the extension and retraction of the sliding rod, the opening or closing of the umbrella frame can be controlled.

[0037] When the umbrella needs to be opened, the control button 72 is pressed, the sliding sleeve is held and pushed upward, the middle umbrella disc remains relatively fixed, the upper umbrella disc 5 and the lower umbrella disc 7 slide relatively and approach, the upper umbrella disc 5 slides downward along the sliding rod 4, the sliding rod 4 shortens as the umbrella stand 2 is opened, the lower umbrella disc 7 slides upward along the stand 1, the long supporting rod 32 and the short supporting rod 31 open the umbrella stand 2 respectively, and the opening of the umbrella is realized. The force is close to the force center in the whole process, the force is more easily exerted, and the gravity of the sliding rod can offset part of the gravity of the umbrella stand, so that the opening is more easily achieved.

[0038] When the umbrella needs to be opened, the control button 72 is pressed, the sliding sleeve is held and pushed upward, the middle umbrella disc remains relatively fixed, the upper umbrella disc 5 and the lower umbrella disc 7 slide relatively and approach, the upper umbrella disc 5 slides downward along the sliding rod 4, the sliding rod 4 shortens as the umbrella stand 2 is opened, the lower umbrella disc 7 slides upward along the stand 1, the long supporting rod 32 and the short supporting rod 31 open the umbrella stand 2 respectively, and the opening of the umbrella is realized. The force is close to the force center in the whole process, the force is more easily exerted, and the gravity of the sliding rod can offset part of the gravity of the umbrella stand, so that the opening is more easily achieved.

[0039] It should be noted that the above enumeration is only one specific embodiment of the utility model. Apparently, the utility model is not limited to the above embodiments, and there are many deformations. In short, all deformations directly derived or thought from the disclosed content by the ordinary skilled in the art should be considered as the protection scope of the utility model.
