Description

Technical Field

[0001] The utility model relates to a parasol, in particular to a hand-pushed opening and closing hanging umbrella. Background Art

[0002] As an outdoor leisure tool, parasols are widely used in leisure places such as squares, beaches, parks and courtyards, providing people with a comfortable space to enjoy the cool. Existing parasols are divided into central column umbrellas and hanging umbrellas according to their structures. Hanging umbrellas are also called side umbrellas and garden umbrellas. They are generally large outdoor umbrellas with large umbrella surface areas, and it is more laborious to open and close the umbrellas.

[0003] There are generally two ways to implement the existing hanging umbrella opening and closing technology. One is to use an umbrella rope to control the opening and closing of the umbrella through a crank rope winding mechanism, and the other is to control the opening and closing of the umbrella through a scissor-type connecting rod mechanism. The above two methods have the following defects: the first method has a long operation time and a complex product structure. The opening and closing function of the entire parasol is achieved by a rope, which poses a safety hazard. The second structure often needs to be coordinated with pneumatic springs or other energy storage components to save effort, otherwise the operation process is laborious.

[0004] After investigation, the existing Chinese patent number CN200920191513.X, "An opening and closing device for a parasol", includes a shell fixed on the middle rod of the parasol and a transmission device, the transmission device includes a fixing frame A and a fixing frame B, the fixing frame A and the fixing frame B are provided with a crank shaft and an umbrella rope shaft, the crank shaft is provided with a small gear, and one end of the crank shaft is provided with a crank; the umbrella rope shaft is provided with a large gear, and the umbrella rope shaft is also provided with an umbrella rope connected to the parasol frame, and the fixing frame B is provided with a ratchet and a ratchet pawl matching the ratchet. When opening and closing the parasol, just shake the crank, the small gear drives the large gear to rotate, pull the umbrella rope, and the umbrella rope pulls the parasol frame to open the parasol. At this time, it is wrapped around the umbrella rope shaft, and the ratchet and pawl play a limiting role to prevent the umbrella surface from sliding down. When closing the parasol, just disengage the pawl and the ratchet. This parasol is a center column umbrella, which is also controlled by umbrella ropes like the traditional ones, and the structure is relatively complicated. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a hand-pushed opening and closing hanging umbrella with a simple and reasonable structure, labor-saving and convenient opening and closing operation, and safe and stable use in view of the above technical status quo.

[0006] The technical solution adopted by the present utility model to solve the above technical problems is as follows: A hand-push open-and-close sunshade umbrella, comprising a vertical column, an inclined rod, a cross rod, an upper umbrella nest, a lower umbrella nest, long umbrella ribs and short umbrella ribs. A slider that can be limited and slide up and down is provided on the vertical column. The lower end of the cross rod is pivotally connected to the slider, and the upper end is pivotally connected to the upper umbrella nest. It is characterized in that: it further comprises a support rod and a strut. The upper end of the inclined rod is pivotally connected to the top of the vertical column, the middle part of the inclined rod is pivotally connected to the middle and lower part of the cross rod, the lower end of the inclined rod is pivotally connected to the support rod, the other end of the support rod is pivotally connected to the middle part of the strut, the upper end of the strut is pivotally connected to the upper middle part of the cross rod, and the lower end of the strut is pivotally connected to the lower umbrella nest. The cross rod, the inclined rod, the support rod and the strut together form a quadrilateral linkage mechanism that can make the opening and closing of the sunshade umbrella labor-saving.

[0007] As an improvement, the specific structure of the middle part of the inclined rod pivotally connected to the middle and lower part of the cross rod is: the width of the cross rod is greater than the width of the inclined rod. A strip-shaped slot for the inclined rod to pass through and rotate is opened along the length direction at the middle and lower part of the cross rod. A first connecting piece is provided at the middle position of the cross rod corresponding to the strip-shaped slot. The inclined rod passes through the strip-shaped slot and is pivotally connected to the cross rod through the first connecting piece.

[0008] Furthermore, a second connecting piece is provided at the upper middle part of the cross rod. The cross rod is pivotally connected to the upper end of the strut through the second connecting piece. The distance between the first connecting piece and the second connecting piece corresponds to the length of the support rod.

[0009] Still further, the cross rod is made of a metal pipe with a horizontal "eye" shape in cross section, and the inclined rod, the support rod and the strut are made of metal pipes with a "square" shape in cross section. Moreover, the support rod is composed of two metal pipes with the same shape and size in the front and back. The gap between the front and back metal pipes of the support rod is not less than the width between the outer walls of the inclined rod and the strut. During installation, pin holes are respectively opened at both ends of the support rod, and through holes corresponding to the pin holes are opened at the lower end of the inclined rod and the middle part of the strut, and they are pivotally connected together through a connecting pin.

[0010] Still further, the structure of the middle part of the inclined rod pivotally connected to the middle and lower part of the cross rod is not limited to the inclined rod passing through the cross rod, and the cross rod passing through the inclined rod can also be adopted. Specifically: the width of the inclined rod is greater than the width of the cross rod. A strip-shaped hole for the cross rod to pass through and rotate is opened along the length direction at the middle part of the inclined rod. The first connecting piece is arranged at the middle part of the inclined rod corresponding to the middle position of the strip-shaped hole. The middle and lower part of the cross rod passes through the strip-shaped hole and is pivotally connected to the middle part of the inclined rod through the first connecting piece.

[0011] Furthermore, the structure of the middle part of the inclined rod pivotally connected to the middle and lower part of the cross rod can also adopt two pipe joints spliced at both ends to jointly form the cross rod. The first connecting piece is arranged at the middle and lower part of the two pipes. The inclined rod passes through the gap between the two pipes and is pivotally connected to the first connecting piece.

[0012] Furthermore, a joint is provided at the top of the vertical column. The upper end of the inclined rod is pivotally connected to the joint.

[0013] Furthermore, a pulley is provided inside the sliding block, and the side surface of the column is formed with at least one track for the pulley to be placed in and slide up and down.

[0014] Finally, the track is a concave track, the cross-section of the column is square, and the four sides of the column are formed with tracks for installing the umbrella stand.

[0015] Compared with the prior art, the advantages of the utility model are: additional support rods and struts are provided, and the horizontal rods, inclined rods, top rods, and struts together form a quadrilateral connecting rod mechanism, which can raise the center of gravity height in the closed umbrella state to the center of gravity height in the open umbrella state, thereby making the product easy to open and close. The utility model has a simple and reasonable structure, is easy to open and close, and has a low cost. Since tracks are provided on the four sides of the column, multiple umbrella stands can be assembled, effectively increasing the sunshade area and improving the effect. The structure is stable and reliable after assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Example 1

[0026] like Figures 1 to 4, as shown in Figures 6 and 7, a hand-pushed and opened / closed hanging umbrella includes a vertical column 1, an inclined rod 2, a cross rod 3, a support rod 4, a strut 5, an upper umbrella nest 6, a lower umbrella nest 7, long umbrella ribs 8 and short umbrella ribs 9. A slider 20 that can be limited and slide up and down is provided on the vertical column 1. The lower end of the cross rod 1 is pivotally connected to the slider 20, and the upper end is pivotally connected to the upper umbrella nest 6. The upper end of the inclined rod 2 is pivotally connected to the top of the vertical column 1. The middle part of the inclined rod 2 is pivotally connected to the middle and lower part of the cross rod 3. The lower end of the inclined rod 2 is pivotally connected to the support rod 4. The other end of the support rod 4 is pivotally connected to the middle part of the strut 5. The upper end of the strut 5 is pivotally connected to the middle and upper part of the cross rod 3. The lower end of the strut 5 is pivotally connected to the lower umbrella nest 7. The cross rod 3, the inclined rod 2, the support rod 4, and the strut 5 together form a quadrilateral linkage mechanism.

[0027] The specific structure of the middle part of the inclined rod 2 being pivotally connected to the middle and lower part of the cross rod 3 is as follows: The width of the cross rod 3 is greater than the width of the inclined rod 2. A strip-shaped slot hole 31 for the inclined rod 2 to pass through and rotate is opened along the length direction at the middle and lower part of the cross rod 3. A first connecting piece a is provided at the middle position of the cross rod 3 corresponding to the strip-shaped slot hole 31. The inclined rod 2 passes through the strip-shaped slot hole 31 and is pivotally connected to the cross rod 3 through the first connecting piece a. A second connecting piece b is provided at the middle and upper part of the cross rod 3. The cross rod 3 is pivotally connected to the upper end of the strut 5 through the second connecting piece b. The distance between the first connecting piece a and the second connecting piece b corresponds to the length of the support rod 4.

[0028] The cross rod 3 is preferably made of a horizontally lying "eye"-shaped metal pipe in cross-section. Of course, an inverted "U"-shaped or "mouth"-shaped metal pipe is also acceptable. The inclined rod 2, the support rod 4, and the strut 5 are preferably made of "mouth"-shaped metal pipes in cross-section. And the support rod 4 is composed of two metal pipes with the same shape and size in the front and back. Of course, the inclined rod 2, the support rod 4, and the strut 5 can also be made of inverted "U"-shaped metal pipes in cross-section.

[0029] In this embodiment, the cross rod 3 is made of a horizontally lying "eye"-shaped metal pipe in cross-section, the inclined rod 2, the support rod 4, and the strut 5 are made of "mouth"-shaped metal pipes in cross-section. And the support rod 4 is composed of two metal pipes with the same shape and size in the front and back. The widths of the inclined rod 2 and the strut 5 in this embodiment are the same. The gap between the front and back metal pipes of the support rod 4 is not less than the width between the outer walls of the inclined rod 2 and the strut 5. During installation, pin holes are respectively opened at both ends of the support rod 4, and corresponding through holes are opened at the lower end of the inclined rod 2 and the middle part of the strut 5, and they are pivotally connected together through a connecting pin. And when the cross rod 3, the inclined rod 2, the strut 5, and the support rod 4 are made of inverted "U"-shaped metal pipes, the U-shaped openings of the cross rod 3, the inclined rod 2, and the strut 5 face downward, the U-shaped opening of the support rod 4 faces upward, the width between the inner walls of the support rod 4 is not less than the width between the outer walls of the inclined rod 2 and the strut 5, and then they are connected.

[0030] A joint 10 is provided at the top of the column 1, and the upper end of the inclined rod 2 is pivotally connected to the joint 10. A pulley 201 is provided in the slider 20, and at least one track 11 is formed on the side of the column 1 for the pulley 201 to be placed and slide up and down. The track 11 of this embodiment is a concave track, and the cross-section of the column 1 is square, and the four sides of the column 1 are formed with tracks 11 on which the umbrella can be installed.

[0031] When opening the umbrella, the upward push slider 20 drives the cross bar 3 to move from a nearly vertical state to a nearly horizontal state, and synchronously drives the support rod 5 to move upward under the drive of the four-sided connecting rod mechanism, thereby raising the height of the lower umbrella nest 7 to complete the umbrella opening. During the umbrella opening process, the center of gravity A of the entire umbrella frame only rises a little in the height direction, making the umbrella opening operation very easy.

[0032] Since the rails 11 are arranged on all four sides of the column 1, the umbrella stand can be installed in a single-head, double-head, triple-head, quad-head, or opposite double-head combination. Figure 7 shown.

[0033] Example 2

[0034] like Figure 5 As shown, a hand-pushed opening and closing hanging umbrella is different from the first embodiment in that: the crossbar 3 is assembled by splicing two pipes 32 with joints 33 at both ends, so that a gap is formed between the two pipes 32 for the inclined rod 2 to pass through, the first connecting member a is arranged at the middle and lower part of the two pipes 32, and the inclined rod 2 passes through the gap between the two pipes 32 and is pivotally connected to the first connecting member a. Others are similar to the first embodiment.

[0035] Example 3

[0036] The structure in which the middle portion of the oblique rod 2 is pivotally connected to the middle and lower portion of the cross rod 3 is not limited to the oblique rod 2 passing through the cross rod 3. The cross rod 3 may also pass through the oblique rod 2, such as Figure 8 Specifically, the width of the oblique rod 2 is greater than that of the cross rod 3, a strip hole is provided in the middle of the oblique rod 2 along the length direction for the cross rod 3 to pass through and rotate, a first connecting member a is arranged in the middle of the oblique rod 2, corresponding to the middle position of the strip hole, and the middle and lower part of the cross rod 3 passes through the strip hole and is pivotally connected to the middle of the oblique rod 2 through the first connecting member a. Others are similar to those in Example 1.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
