DETAILED DESCRIPTION
[0019] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.
[0020] A parasol for stalls, such as Figure 1and Figure 3 As shown, it includes an umbrella handle 1 and an umbrella surface 2, the umbrella handle 1 is slidably connected with a support member 3, the top of the umbrella handle 1 is fixedly connected with an upper nest, and a plurality of main bones 4 that fit the umbrella surface 2 are rotatably connected to the upper nest, and the movable ends of the main bones 4 are fixedly connected to the edges of the umbrella surface 2, the support member 3 and the main bones 4 are connected through branch bones 5, and a lower nest is fixedly connected to the support member 3, one end of a plurality of branch bones 5 are rotatably connected to the lower nest, and the other ends of a plurality of branch bones 5 are rotatably connected to the corresponding main bones 4, and the number of main bones 4 and branch bones 5 is equal, and an elastic oil shielding cloth 6 is detachably connected to the umbrella surface 2, and the main bones 4 and the branch bones 5 are both accommodated between the oil shielding cloth 6 and the umbrella surface 2, and a plurality of fixing members 7 for fixing to the branch bones 5 are provided on one side of the oil shielding cloth 6, and the number of the fixing members 7 is equal to the number of the paper The number of ribs 5 is large, and the oil-blocking cloth 6 covers the inner side of the umbrella surface 2, all the supporting ribs 5 and all the main ribs 4, so that the oil smoke under the umbrella surface 2 is blocked by the oil-blocking cloth 6, thereby ensuring the cleanliness of the inner side of the umbrella surface 2 and each supporting rib 5 and the main rib 4, and the oil-blocking cloth 6 is detachable, so that people only need to remove the oil-blocking cloth 6 for cleaning, so that there is no need to move the entire parasol, and the oil-blocking cloth 6 is a soft fabric, which can be rubbed and washed during cleaning and has a light overall weight, so that it is convenient for people to clean it. When the umbrella surface 2 is fully opened by several supporting ribs 5, the supporting member 3 is located below the edge of the umbrella surface 2, and when several fixing members 7 are fixed on the supporting ribs 5, the cross-section of the oil-blocking cloth 6 is set in a W shape. 5, the cross section of the oilproof cloth 6 is set in a V shape. When setting up a stall in high temperature weather, people connect the edge of the oilproof cloth 6 to the edge of the umbrella surface 2, and connect the center of the oilproof cloth 6 to the support member 3, so that the cross section of the oilproof cloth 6 is V-shaped. The oilproof cloth 6 with a V-shaped cross section makes the center position of the oilproof cloth 6 low and the edge position of the oilproof cloth 6 high, so that when the oil smoke and hot air float under the umbrella surface 2, the oil smoke is adsorbed on the oilproof cloth 6, and the hot air will diffuse from the plane of the oilproof cloth 6 to the edge, so that the heat under the umbrella surface 2 is not easy to accumulate, and the top of the head of people is not easy to overheat. When people set up a stall in low temperature weather, people connect the edge of the oilproof cloth 6 to the edge of the umbrella surface 2, connect the center of the oilproof cloth 6 to the support member 3, and connect the oilproof cloth 6 located at the bottom of the umbrella surface 2 to the bottom of the umbrella surface 2. The fixing piece 7 on the oil shield cloth 6 is fixed on the support frame 5, so that the height of the oil shield cloth 6 increases when the center of the oil shield cloth 6 is at the position of the fixing piece 7, and the height starts to decrease when the position of the fixing piece 7 is at the edge of the oil shield cloth 6, so that the cross-section of the oil shield cloth 6 is W-shaped as a whole, so that the oil shield cloth 6 forms an annular receiving groove with a V-shaped cross-section under the umbrella surface 2. When the oil smoke and hot air drift into the annular receiving groove, the oil smoke is adsorbed on the oil shield cloth 6, and the hot air will be contained in the annular receiving groove, making it difficult for the hot air to diffuse quickly along the surface of the oil shield cloth 6, thereby ensuring the temperature under the umbrella surface 2. This arrangement makes it possible to change the shape of the cross-section of the oil shield cloth 6 according to whether the fixing piece 7 is fixed on the support frame 5, so that the oil shield cloth can adapt to weather with different temperatures.
[0021] like Figure 3 and Figure 4As shown, a fixing ring 8 for fixing the oil baffle 6 on the support member 3 is provided at the center position of the oil baffle 6, and a plurality of through holes 9 for the movable end of the main frame 4 to pass through are opened near the edge of the oil baffle 6, and a limiting column 10 is threadedly connected to the movable end of the main frame 4, and the diameter of the limiting column 10 is larger than the diameter of the through hole 9. When people need to fix the oil baffle 6 under the umbrella surface 2, people first fix the fixing ring 8 on the support member 3 to complete the fixation of the center position of the oil baffle 6, fold the edge position of the oil baffle 6 toward the position of the umbrella surface 2 and pass the main frame 4 through the through hole 9, and then thread the limiting column 10 on the main frame 4. When the oil baffle 6 is fixed on the umbrella surface 2, the oil baffle 6 is always in a deformed state. This arrangement ensures that the oil baffle 6 can be easily deformed after it is deformed. The edge of the cloth 6 is subjected to a pulling force toward its center, so that the through hole 9 does not separate from one end of the main frame 4, and the diameter of the limiting column 10 is larger than the diameter of the through hole 9, so that under the action of the limiting column 10, the fixing effect of the edge of the oil-proof cloth 6 is guaranteed, and the fixing strength of the oil-proof cloth 6 is guaranteed, and the edge of the oil-proof cloth 6 is folded up, so that the gap between the edge of the umbrella surface 2 and the edge of the oil-proof cloth 6 can be covered to a certain extent, thereby forming an air cavity between the umbrella surface 2 and the oil-proof cloth 6, and the main frame 4 and the supporting frame 5 are both located in the air cavity, and the outer edge of the air cavity is covered by the oil-proof cloth 6, so that the air in the air cavity flows slowly, so that the air cavity has a certain temperature insulation effect, so that in winter, the temperature on the umbrella surface 2 It is not easy to quickly penetrate into the oil-proof cloth 6, so that the hot air under the oil-proof cloth 6 is not easy to cool down quickly, which ensures the temperature below the umbrella surface 2. A threaded portion is arranged on the outer peripheral wall of the support member 3, and the threaded portion is located in the middle position of the support member 3. An internal thread for connecting with the threaded portion is arranged on the inner wall of the fixing ring 8. An annular groove 11 is arranged on the outer peripheral wall of the fixing ring 8. A rotating ring 12 with a T-shaped cross section is rotatably connected in the annular groove 11. The outer peripheral wall of the rotating ring 12 is fixedly connected to the oil-proof cloth 6. A circular hole is arranged in the center of the oil-proof cloth 6. The outer peripheral wall of the rotating ring 12 is fixed on the inner peripheral wall of the circular hole. An umbrella buckle 13 for limiting its movement on the umbrella handle 1 is arranged on the support member 3. The fixing ring 8 is located below the umbrella buckle 13, and the umbrella buckle 13 will never be exposed outside the outer wall of the support member 3. When people need to install the fixing ring 8 on the support 3, they pass the umbrella handle 1 through the cavity in the center of the fixing ring 8 and move along the umbrella handle 1 to the bottom of the support 3, and then slowly move the fixing ring 8 along the length direction of the support 3 until the fixing ring 8 slides over the umbrella buckle 13 and moves to the position of the threaded portion of the support 3, and then people rotate the fixing ring 8 so that the internal thread on the fixing ring 8 is threadedly connected to the threaded portion of the support 3. In this process, because the rotating ring 12 is rotatably connected in the ring groove 11, people use their hands to limit the movement of the rotating ring 12 during the rotation of the fixing ring 8. At this time, the rotating ring 12 and the fixing ring 8 rotate relative to each other, and the rotating ring 12 rotates, so that the center position of the oil shield cloth 6 is not prone to wrinkles 23.The fixing ring 8 and the support member 3 are fixed by threaded connection. The thread has self-locking property, which ensures the fixing strength between the two. At this time, the umbrella buckle 13 is arranged below the fixing ring 8, so that when the fixing ring 8 is fixed on the support member 3, the fixing ring 8 will not affect the use of the umbrella buckle 13, so that the umbrella buckle 13 can still be used normally.
[0022] like Figure 1 and Figure 2As shown, the fixing member 7 includes a threaded column 14 and two clamping rings 15 fixed on the outer peripheral wall of the threaded column 14, the oil shielding cloth 6 is clamped between the two clamping rings 15, and a mounting seat is fixed to the end of the support frame 5 facing away from the umbrella handle 1, and a threaded hole 16 for being embedded by the threaded column 14 is opened on the mounting seat. People achieve the connection of the fixing member 7 by threading the threaded column 14 on the mounting seat. The threaded fixing has high strength, so that after the fixing member 7 is fixed, the fixing member 7 is not easy to be separated from the mounting seat. This arrangement ensures that the connection strength of the shielding cloth on the parasol is always high regardless of whether the cross-section is W-shaped or V-shaped, so that each part of the shielding cloth is not easy to be separated from the parasol, and the oil shielding cloth 6 is elastic, so that people can When the sliding support 3 is used to close the parasol, the oilproof cloth 6 does not need to be disassembled. The oilproof cloth 6 can change its extension amount according to the change of the position of the support 3 on the umbrella handle 1, so that people can disassemble it when there is a lot of oil stains on the oilproof cloth 6. A number of through holes are opened on the oilproof cloth 6, and a metal ring 18 for being passed by the threaded column 14 is fixedly connected to the inner wall of the through hole. The metal ring 18 is clamped between two clamping rings 15. The outer diameter of the clamping ring 15 is larger than the diameter of the through hole. The setting of the through hole enables the threaded column 14 to rotate relative to the oilproof cloth 6, thereby realizing the connection with the mounting seat. When people need to set the cross-section of the oilproof cloth 6 in a W-shape, people first fix the fixing ring 8 and the support 3, then fix the threaded column 14 and the mounting seat, and finally fix the oilproof cloth 6. The edge of the oilcloth 6 makes it possible for people to fix the threaded column 14 and the mounting seat without connecting the edge of the oilcloth 6 to the main bone 4, so that there is enough space between the support bone 5 and the oilcloth 6 for connecting the two. The setting of the metal ring 18 ensures the overall safety and makes it difficult for the perforation to tear. The metal ring 18 is also arranged on the inner circumferential wall of the through hole 9. A cross groove 17 is provided at one end of the threaded column 14. The setting of the cross groove 17 allows people to use a screwdriver to tighten the threaded column 14 in the threaded hole 16, making it easier for people to tighten the threaded column 14. A guide hole connected to the threaded hole 16 is provided on the side of the mounting seat facing away from the umbrella cover 2. The diameter of the guide hole is larger than the major diameter of the threaded hole 16, and a threaded part for attracting the thread is fixed on the inner wall of the guide hole. The magnetic ring 19 of the column 14, wherein the main bone 4 and the branch bone 5 are both made of glass fiber, the setting of the magnetic ring 19 can have a certain guiding effect on the installation of the threaded column 14, so that when the threaded column 14 is aligned with the threaded hole 16, the magnetic ring 19 can attract the threaded column 14, thereby attracting the threaded column 14 toward the guide hole, so that the threaded column 14 can enter the guide hole more conveniently, the inner diameter of the magnetic ring 19 is equal to the major diameter of the threaded hole 16, so that after the threaded column 14 enters the guide hole, the threaded column 14 can be directly rotated to be more conveniently threadedly connected with the threaded hole 16, and the main bone 4 and the branch bone 5 are both made of glass fiber, and the glass fiber will not be attracted by the magnetic ring 19, thereby reducing the interference of the umbrella ribs with the magnetic ring 19,Secondly, glass fiber has the characteristics of high strength and good toughness, thus ensuring the overall strength of the umbrella ribs.
[0023] like Figure 6 As shown, the threaded column 14 includes a first part 24 and a second part 25, and two clamp rings 15 are integrally formed on the first part 24 and the second part 25 respectively. The first part 24 is provided with a square groove 26 running through its length direction, and the second part 25 is fixedly connected with a square column 27 for extending into the square groove 26, wherein the external thread on the threaded column 14 for connecting with the threaded hole 16 is arranged on the first part 24, and a mounting hole is arranged on the side of the square column 27 facing away from the second part 25, and a resisting column 28 is threadedly connected in the mounting hole, and the resisting column 28 resists the outer edge of the square groove 26, so that the square column 27 cannot be separated from the square groove 26, and the cross groove 17 is arranged on the side of the second part 25 facing away from the square column 27, which ensures the connection between the first part 24 and the second part 25. This arrangement enables people to fix the threaded column 14 in the through hole when people need to fix the threaded column 14 in the through hole. The square column 27 on the second part 25 is first passed through the through hole, and then the upper groove 26 of the first part 24 is put on the square column 27 on the second part 25, and finally the interference column 28 is threadedly connected to the mounting hole of the square column 27. This arrangement makes it easier for the threaded column 14 to be installed on the oil baffle cloth 6, so that it is convenient for people to install the threaded column 14. Secondly, this installation method allows people to remove the threaded column 14 from the oil baffle cloth 6 when cleaning the oil baffle cloth 6. Because the interference column 28 is threadedly connected to the mounting hole, the threaded column 14 can be easily removed from the oil baffle cloth 6. In this way, the oil baffle cloth 6 will not be interfered with by the threaded column 14 during cleaning, and the threaded column 14 will not be rubbed during hand rubbing, making the process of cleaning the oil baffle cloth 6 more convenient.
[0024] like Figure 5As shown, the cross-section of the oil-blocking cloth 6 is circular, and a plurality of threaded columns 14 are distributed in a circular array with the central axis of the oil-blocking cloth 6 as the axis. The oil-blocking cloth 6 is divided into a low-elastic portion 20 and a high-elastic portion 21 with the circular path in which the threaded columns 14 are arranged as the dividing line, wherein the through holes 9 and the perforations are both arranged on the low-elastic portion 20. This arrangement allows the deformation position of the oil-blocking cloth 6 to be concentrated on the high-elastic portion 21, so that the deformation amount on the low-elastic portion 20 is small, thereby making the deformation amount of the through holes 9 and the perforations small, thereby ensuring the integrity of the through holes 9 and the perforations as a whole. The high-elastic portion 21 is compounded with an elastic layer 22 on the side facing the umbrella surface 2, and the elastic layer 22 is arranged in a ring shape, and the side of the elastic layer 22 facing away from the high-elastic portion 21 is formed with a plurality of circular folds coaxially arranged with the elastic layer 22 Wrinkles 23, a cavity is formed between the wrinkles 23 and the high-elastic part 21. During the deformation of the high-elastic part 21, the gaps between the yarns will increase, especially when the cross-section of the oil-blocking cloth 6 is W-shaped, the deformation degree of the high-elastic part 21 is relatively large. The setting of the elastic layer 22 enables the wrinkles 23 to provide a certain buffer for the deformation of the high-elastic part 21. During the deformation, the wrinkles 23 on the elastic part will gradually flatten, so that the high-elastic layer can reduce a certain amount of deformation by buffering with the wrinkles 23, so that the deformation degree of the elastic layer 22 is relatively small, and the weaving density of the elastic layer 22 is greater than the weaving density of the high-elastic part 21, so that the yarn spacing on the elastic layer 22 is relatively small, and oil stains are not easy to penetrate the elastic layer 22, thereby ensuring the cleaning performance of the umbrella surface 2 and the umbrella ribs as a whole.
[0025] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
