Description

Technical Field

[0001] This invention belongs to the field of outdoor sunshades, and particularly relates to a liftable parasol. Background Technology

[0002] Outdoor sun umbrellas are widely used in courtyards, parks, open-air shopping malls, and other places, and are a common tool for outdoor sunshade. One type of outdoor Roman umbrella includes an umbrella column and an umbrella frame. The umbrella column and the umbrella frame are connected by a hinge between an upper seat fixed to the top of the umbrella column and a sliding seat that is slidably connected to the umbrella column. Driven by a drive mechanism, the sliding seat rises and unfolds the umbrella frame. When not in use, the sliding seat is retracted. The upper seat of this type of Roman umbrella is fixed to the top of the umbrella column, the height of the umbrella frame cannot be adjusted as needed, and the umbrella frame is still at a relatively high height when folded, making it inconvenient for storage and transportation. Summary of the Invention

[0003] The purpose of this invention is to provide a lifting umbrella to solve the above-mentioned technical problems.

[0004] To solve the above-mentioned technical problems, the specific technical solution of the present invention for a lifting umbrella is as follows: A lifting umbrella includes an umbrella column and an umbrella frame. A slide is mounted on the umbrella column, and a diagonal rod is hinged to the slide. The other end of the diagonal rod is fitted into the umbrella frame. An upper seat is also mounted on the umbrella column, located above the slide. The upper seat can move up and down along the umbrella column. A diagonal pull rod is hinged to the upper seat, and the other end of the diagonal pull rod is hinged to the diagonal rod. The umbrella also includes a limiting mechanism, a linkage mechanism, and a moving mechanism. The limiting mechanism restricts the upper seat from being positioned at the upper end of the umbrella column. The linkage mechanism enables synchronous movement of the upper seat and the slide. The moving mechanism drives the slide to move up and down along the umbrella column. When the umbrella frame is closed, the linkage mechanism connects the upper seat and the slide, the limiting mechanism unlocks the upper seat, and the moving mechanism drives the slide to move downwards, causing the entire umbrella frame to move downwards.

[0005] Furthermore, the limiting mechanism includes a limiting slide, a limiting top rod, and a locking mechanism. The limiting slide is fixedly installed on one side of the top of the umbrella column, located inside the upper seat. The limiting slide has a groove that slopes upward from the outside to the inside. The upper end of the limiting top rod has a top block, which is slidably connected to the groove and can slide within the groove. When the top block is at the bottom of the groove, it protrudes from the surface of the umbrella column and abuts against the bottom of the upper seat, restricting the vertical movement of the upper seat. When the top block is at the top of the groove, it retracts into the surface of the umbrella column, and the upper seat can slide vertically along the umbrella column. The lower end of the limiting top rod is connected to the locking mechanism, which drives the top block to move, thereby unlocking and unlocking the upper seat.

[0006] Furthermore, the locking mechanism includes a fixed lock seat, a pull rod, and a pull ring. The fixed lock seat is fixedly installed at the lower end of the umbrella column. The upper end of the fixed lock seat is hinged to the inner side of the upper end of the pull rod. The lower end of the limiting top rod is hinged to the outer side of the upper end of the pull rod. The lower end of the pull rod is fixedly connected to the pull ring.

[0007] Furthermore, when the locking mechanism is engaged, the pull rod is vertical and fixed to the fixed lock seat via a latch. The limiting top rod is located at the lowest position on the outer side of the umbrella column. When the top block on the limiting top rod is at the bottom of the slide groove, the top block protrudes from the surface of the umbrella column and abuts against the bottom of the upper seat, restricting the vertical movement of the upper seat. When unlocking, pull the ring to separate the pull rod from the fixed lock seat. At the same time, the top of the pull rod moves upward at the hinge point with the limiting top rod, causing the limiting top rod to move upward. With the help of thrust, the limiting top rod is pushed upward and close to the surface of the umbrella column. At this time, when the top block on the limiting top rod is at the upper end of the slide groove, the top block retracts into the surface of the umbrella column, and the upper seat can slide vertically along the umbrella column.

[0008] Furthermore, the linkage mechanism includes a linkage fixing rod, a fixing seat, and a pin. The linkage fixing rod is vertically fixedly connected to the upper seat and can slide along the umbrella column. The fixing seat is fixedly connected to the lower end of the linkage fixing rod and also fixedly connected to the slide. The fixing seat has a first insertion hole, and the inclined pull rod has a second insertion hole. When the umbrella frame is closed, the second insertion hole of the inclined pull rod is aligned with the first insertion hole of the fixing seat. The pin is inserted into the first and second insertion holes to lock the inclined pull rod to the fixing seat, thereby realizing the linkage and sliding of the umbrella frame with the upper seat and the slide.

[0009] Furthermore, the moving mechanism includes a pulley block, a timing belt, and a rocker arm. The timing belt is fixed inside the umbrella column by the pulley block, the slide block is fixedly connected to the timing belt, and the rocker arm is used to manually drive the pulley block to rotate, thereby driving the timing belt to move up and down, and thus driving the slide block to move up and down.

[0010] Furthermore, the pulley group includes a driving pulley, a first driven pulley group, and a second driven pulley group. The driving pulley is fixedly installed inside the umbrella column and meshes with the timing belt. The first driven pulley group connects the timing belt and the driving pulley in an S-shape. The second driven pulley group is fixedly installed at the upper and lower ends inside the umbrella column, respectively. The timing belt passes through the second driven pulley group, realizing the vertical movement of the timing belt.

[0011] Furthermore, the driven pulley group one includes two driven pulleys, which are respectively disposed at the upper and lower ends of the driving pulley. The timing belt passes through the driven pulley, the driving pulley, and the driven pulley respectively. The driven pulley group one makes the timing belt and the driving pulley connected in an S-shape.

[0012] Furthermore, the drive wheel shaft is exposed on the surface of the umbrella column, and the shaft is polygonal. The remote control is inserted into the shaft and can manually drive the drive wheel to rotate.

[0013] The lifting umbrella of the present invention has the following advantages: The lifting umbrella of the present invention has a limiting mechanism, a linkage mechanism and a moving mechanism. The limiting mechanism is used to restrict the upper seat to be located at the upper end of the umbrella column. The linkage mechanism is used to realize the synchronous movement of the upper seat and the slide. The moving mechanism is used to drive the slide to move up and down along the umbrella column. When the umbrella frame is closed, the linkage mechanism realizes the connection between the upper seat and the slide. The limiting mechanism completes the limiting and unlocking of the upper seat. The moving mechanism drives the slide to move down continuously and drives the upper seat 13 to move down along the umbrella column 1, so that the entire umbrella frame moves down. The present invention can drive the umbrella frame to lift and lower, which is convenient for storage and transportation. Attached Figure Description

[0015] To better understand the purpose, structure, and function of this invention, a lifting umbrella of this invention will be described in further detail below with reference to the accompanying drawings.

[0016] like Figure 1As shown, a lifting umbrella of the present invention includes an umbrella column 1 and an umbrella frame 2. A slide block 11 is provided on the umbrella column 1, and a diagonal rod 12 is hinged to the slide block 11. The other end of the diagonal rod 12 is fitted into the umbrella frame 2. An upper seat 13 is also provided on the umbrella column 1, located above the slide block 11. The upper seat 13 can move up and down along the umbrella column 1. A diagonal pull rod 14 is hinged to the upper seat 13, and the other end of the diagonal pull rod 14 is hinged to the diagonal rod 12. The invention also includes a limiting mechanism 3, a linkage mechanism 4, and a moving mechanism. 5. The limiting mechanism 3 is used to restrict the upper seat 13 from being located at the upper end of the umbrella column 1. The linkage mechanism 4 is used to realize the synchronous movement of the upper seat 13 and the slide 11. The moving mechanism 5 is used to drive the slide 11 to move up and down along the umbrella column 1. When the umbrella frame 2 is closed, the linkage mechanism 4 realizes the connection between the upper seat 13 and the slide 11. The limiting mechanism 3 completes the limiting and unlocking of the upper seat. The moving mechanism 5 drives the slide 11 to move down continuously and drives the upper seat 13 to move down along the umbrella column 1, so that the entire umbrella frame 2 moves down.

[0017] like Figure 2As shown, the limiting mechanism 3 includes a limiting slide 31, a limiting top rod 32, and a locking mechanism 33. The limiting slide 31 is fixedly installed on one side of the top of the umbrella column 1, located inside the upper seat 13. The limiting slide 31 has a sliding groove 311 that slopes upward from the outside to the inside. The upper end of the limiting top rod 32 has a top block 321, which is slidably connected to the sliding groove 311 and can slide within the sliding groove 311. When the top block 321 is at the bottom of the sliding groove 311, the top block 321 protrudes from the surface of the umbrella column 1 and abuts against the bottom of the upper seat 13, restricting the vertical movement of the upper seat 13. When the top block 321 is at the upper end of the sliding groove 311, the top block 321 retracts into the surface of the umbrella column 1, and the upper seat 13 can slide vertically along the umbrella column 1. The lower end of the limiting top rod 32 is connected to the locking mechanism 33, which drives the top block 321 to move, thereby unlocking and unlocking the upper seat 13. The locking mechanism 33 includes a fixed lock seat 331, a pull rod 332, and a pull ring 333. The fixed lock seat 331 is fixedly installed at the lower end of the umbrella column 1 at a height suitable for hand operation. The upper end of the fixed lock seat 331 is hinged to the inner side of the upper end of the pull rod 332, and the lower end of the limiting rod 32 is hinged to the outer side of the upper end of the pull rod 332. The lower end of the pull rod 332 is fixedly connected to the pull ring 333. In the locked state, the pull rod 332 is in a vertical state. The pull rod 332 and the fixed lock seat 331 are fixedly connected by a latch (not shown in the figure, any latch connection method can be used). The limiting rod 32 is located at the lowest position on the outer side of the umbrella column 1. When the top block 321 on the limiting rod 32 is at the bottom of the slide groove 311, the top block 321 protrudes from the surface of the umbrella column 1 and abuts against the bottom of the upper seat 13, restricting the vertical movement of the upper seat 13. When unlocking, pull the ring 333 to separate the pull rod 332 from the fixed lock seat 331. At the same time, the top of the pull rod 332 moves upward at the hinge point with the limiting rod 32, which drives the limiting rod 32 to move upward. With the help of the thrust, the limiting rod 32 can be pushed up and close to the surface of the umbrella column 1. At this time, when the top block 321 on the limiting rod 32 is at the upper end of the slide groove 311, the top block 321 retracts into the surface of the umbrella column 1, and the upper seat 13 can slide vertically along the umbrella column 1.

[0018] like Figure 3 As shown, the linkage mechanism 4 includes a linkage fixing rod 41, a fixing seat 42, and a pin 43. The linkage fixing rod 41 is vertically fixedly connected to the upper seat 13 and can slide along the umbrella column 1. The fixing seat 42 is fixedly connected to the lower end of the linkage fixing rod 41 and is also fixedly connected to the slide 11. The fixing seat 42 has a first insertion hole 421, and the diagonal pull rod 14 has a second insertion hole 141. When the umbrella frame 2 is closed, the second insertion hole 141 of the diagonal pull rod 14 is aligned with the first insertion hole 421 of the fixing seat 42. The pin 43 is inserted into the first insertion hole 421 and the second insertion hole 141 to lock the diagonal pull rod 14 to the fixing seat 42, thereby realizing the linkage sliding of the umbrella frame 2 with the upper seat 13 and the slide 11.

[0019] like Figure 4As shown, the moving mechanism 5 includes a pulley block 51, a synchronous belt 52, and a rocker arm 53. The synchronous belt 52 is fixed inside the umbrella column 1 via the pulley block 51. The slide block 11 is fixedly connected to the synchronous belt 52. The rocker arm 53 is used to manually drive the pulley block 51 to rotate, causing the synchronous belt 52 to move up and down, thereby causing the slide block 11 to move up and down. Since the linkage mechanism 4 realizes the linkage between the umbrella frame 2, the upper seat 13, and the slide block 11, the umbrella frame 2 and the upper seat 13 move together with the slide block 11, which can realize the height extension and retraction of the umbrella frame 2, making it easier to store and transport. Specifically, the pulley block 51 includes a driving wheel 511, a driven wheel group one 512, and a driven wheel group two 513. The driving wheel 511 is fixedly installed inside the umbrella column 1 and meshes with the synchronous belt 52. Driven wheel assembly 512 includes two driven wheels, respectively positioned at the upper and lower ends of the driving wheel 511. A synchronous belt 52 passes through the driven wheels, driving wheel 511, and another driven wheel. Driven wheel assembly 512 forms an S-shaped connection between the synchronous belt 52 and the driving wheel 511, enhancing the connection tightness and preventing slippage and deviation. Driven wheel assembly 513 is fixedly installed inside the upper and lower ends of the umbrella column 1. The synchronous belt 52 passes through driven wheel assembly 513, enabling vertical movement of the synchronous belt 52. The shaft of the driving wheel 511 protrudes from the surface of the umbrella column 1. The shaft is polygonal, and a lever 53 passes through the shaft to manually rotate the driving wheel 511.

[0020] In use, first fold up the umbrella frame 2, then insert the pin 43 of the linkage mechanism 4 into the second insertion hole 141 of the diagonal pull rod 14 and the first insertion hole 421 of the fixed seat 42 to lock the diagonal pull rod 14 and the fixed seat 42. Then pull the pull ring 333 to separate the pull rod 332 from the fixed lock seat 331, and the top block 321 retracts into the surface of the umbrella column 1 to unlock the upper seat 13. Then, the rocker arm 53 drives the entire upper seat 13, slide 11 and umbrella frame 2 to move downward to reduce the overall height.
