Technical Field

[0001] The utility model belongs to the field of rain shelters, and particularly relates to an umbrella-shaped steel frame column simple rain shelter. Background Art

[0002] The rain shelter with a steel structure and membrane structure is a new type of agricultural facility, which is mainly used to protect crops from adverse weather (such as heavy rain, high temperature, cold, etc.) and improve the yield and quality of crops. The rain shelter with a steel structure and membrane structure has the characteristics of light self-weight and good stress, and plays an important role in the construction of rain shelters. The rain shelter with a steel structure and membrane structure with a unique shape can not only meet the basic functions such as wind and rain protection and sun protection, but also has a good attracting effect.

[0003] For example, the patent with the Chinese patent publication number CN 207776515 U discloses a rain shelter with a steel structure and membrane structure. The lower sides of the front and rear ends of its rectangular steel frame are both provided with main support columns; the middle positions of the left and right ends of the rectangular steel frame are both vertically provided with secondary support columns; a horizontal support steel pipe is welded at the longitudinal middle position inside the rectangular steel frame, and a top column is arranged at the middle position on the upper side of the horizontal support steel pipe; an umbrella cap is arranged at the upper end of the top column; a plurality of inclined support steel pipes are radially arranged below the umbrella cap, and both ends of each inclined support steel pipe are connected to the top column and the rectangular steel frame through connectors; at least one upper end and one lower end of the inclined support steel pipe are respectively fixed with connection buckles; pressing plates are arranged inside both sides of the connection buckles, and the connecting part of the tension membrane extends into the lower side of the pressing plate and between the connection buckles; locking bolts are arranged on both sides of the connection buckles so that the tension membrane is clamped.

[0004] This rain shelter provides a rain shelter with a steel structure and membrane structure different from the prior art, and has the advantages of novel and stable structure. However, this structure is not easy to disassemble and transport after installation, and has low flexibility. Therefore, this scheme proposes an umbrella-shaped steel frame column simple rain shelter, which adopts an umbrella-shaped structure design and is fixed on the ground. No civil engineering is required during erection, it is easy to install, has a simple structure, strong adaptability, and also has the advantages of small density, lightness, good ventilation performance, etc., and can be applied to the production of fruits, vegetables and other crops. Content of the Utility Model

[0005] In order to solve the problem that the rain shelter is not easy to disassemble and transport after installation and has low flexibility, the utility model provides an umbrella-shaped steel frame column simple rain shelter, which adopts an umbrella-shaped structure design and is fixed on the ground. No civil engineering is required during erection, it has a simple structure, is easy to install and flexible, and has strong adaptability.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a simple rainproof shed with umbrella-shaped steel frame columns, including a plurality of shed bodies, the shed bodies including hollow columns, sliding rings are arranged outside the columns, a plurality of connecting rods are hinged along the circumference of the sliding rings, a supporting rod is hinged at one end of the connecting rod away from the sliding ring, one end of the supporting rod is hinged to the top of the column, and a shed film is fixedly connected to the top of the support rod.

[0007] The side wall of the column is rotatably connected to a first shaft, the first shaft penetrates the side wall of the column, a gear is coaxially fixedly connected to the first shaft, a locking mechanism is provided on one side of the gear, a first rack and a second rack are respectively meshed on both sides of the gear, the first rack and the second rack are both slidably matched with the inner wall of the column; a slider is fixedly connected to the inner wall of the sliding ring, the slider penetrates the side wall of the column and extends into the column, a sliding groove is provided on the side wall of the column, the slider is located in the sliding groove and slidably matched with the sliding groove; the top of the first rack is fixedly connected to the slider.

[0008] A moving block is fixedly connected to the bottom of the second rack, and the moving block is slidably matched with the inner wall of the column. A plurality of reinforcing rods are hinged at the bottom of the moving block, and a plurality of through holes are provided at the bottom of the column. The reinforcing rods pass through the through holes and are slidably matched with the through holes.

[0009] The principle and beneficial effects of the above scheme are as follows: when using the rain shelter, the bottom end of the column is inserted into the position of the required rain shelter, and the personnel rotates the first shaft. When the first shaft rotates, the gear is driven to rotate. Since the first rack and the second rack are respectively engaged on both sides of the gear, the rotation of the gear will drive the first rack to move vertically upward, and the rotation of the gear will drive the second rack to move vertically downward.

[0010] When the first rack moves upward, it drives the slider to slide in the slide groove, and at the same time pushes the sliding ring to slide upward. When the sliding ring moves upward, the connecting rod supports the support rod to form an open umbrella shape, and the greenhouse film is used to prevent rain. At the same time, the second rack moves downward to drive the moving block to move downward. At this time, the reinforcement rod passes through the through hole and is inserted obliquely into the soil, thereby increasing the contact area between the bottom of the column and the soil, increasing the stability of the column, and making it more wind-resistant. This insertion method can effectively save labor and material costs, and use the force of the greenhouse film to deepen the foundation, saving manpower. Therefore, an umbrella-shaped structure design is adopted and fixed on the ground. No civil engineering work is required during erection. It has a simple structure, convenient and flexible installation, and strong adaptability.

[0011] Furthermore, the locking mechanism includes a ratchet, a pawl and a spring. The ratchet is coaxially fixedly connected to the first shaft, the inner wall of the column is fixedly connected to the second shaft, the pawl is sleeved on the second shaft, the pawl cooperates with the ratchet, the spring is fixedly connected to one side of the pawl, and the end of the spring away from the pawl is fixedly connected to the inner wall of the column.

[0012] Beneficial effect: When the locking mechanism is used, the rotation of the gear drives the ratchet to rotate, and then through the cooperation with the pawl and the spring, the ratchet and the gear can only rotate in one direction and are automatically locked.

[0013] Furthermore, a third shaft is fixedly connected to one side of the pawl, and the third shaft passes through the side wall of the column. The side wall of the column is provided with a limiting groove, and the third shaft passes through the limiting groove and slidably cooperates with the limiting groove.

[0014] Beneficial effect: by toggling the third shaft, the third shaft is disengaged from the ratchet when sliding in the limit groove, so that the limiting effect of the pawl on the ratchet disappears, and then the gravity of the support rod is used to make the support rod droop away from one end of the column, and the rainproof awning is automatically folded.

[0015] Furthermore, a fourth shaft is fixedly connected to the first shaft outside the column, and a handle is rotatably connected to one end of the fourth shaft away from the first shaft.

[0016] Beneficial effect: Using the fourth axis and the handle to rotate the first axis is more convenient and labor-saving.

[0017] Furthermore, the bottom end of the column is connected to a puncture tube, the bottom end of the puncture tube is in an inverted cone shape, and the through hole is located at the bottom of the puncture tube.

[0018] Beneficial effect: The puncture tube with an inverted cone-shaped bottom end can be easily inserted into the soil.

[0019] Furthermore, the height of the shed is greater than 2m, the width of the shed when expanded is 2.4m, the shoulder height of the shed when expanded is greater than 1.5m, and the distance between the columns is less than 3m.

[0020] Beneficial effects: The height of the awning is greater than 2 meters, which can provide sufficient internal space. The width of the awning when opened is 2.4 meters, which can meet the sunshade and rain protection needs within a certain range. The shoulder height of the awning when opened is greater than 1.5 meters, which can ensure the normal activities and passage of people in the awning without feeling crowded and cramped. The distance between columns is less than 3 meters, which can not only increase the stability of the awning, but also enhance the landscape effect to a certain extent.

[0021] Furthermore, the thickness of the greenhouse film is 0.08 mm to 0.12 mm, and the greenhouse film is a drip-free film.

[0022] Beneficial effects: The drip-free film can avoid dripping caused by the accumulation of dew or condensate, thus protecting the personnel and items in the site from being wet by water droplets. The film material is economical and practical, which can reduce the construction cost. The film material has good flexibility, so for the erection of some complex shapes such as semi-circular and umbrella-shaped, the shed film is easier to fix, and even a large awning can be handled. The installation is convenient and fast. The shed film has very good light transmittance, which can allow natural light to pass through and evenly irradiate the inside of the shed, providing good lighting conditions for the operations, activities and plantings inside the shed. To a certain extent, the film material is more environmentally friendly than traditional materials such as glass and cement, and is easy to recycle, shortening the construction time on the construction site, reducing the construction period and the maintenance difficulty of waterproofing and plugging leaks.

[0023] Further, the shed film is fixed by a hot-dip galvanized card slot or an aluminum alloy card slot with a thickness of 0.8 mm to 1.0 mm through a plastic-coated clamping spring.

[0024] Beneficial effects: The card slots and clamping springs are all finished products, and the structure is simple, and the assembly and installation are convenient and fast. The hot-dip galvanized card slot or the aluminum alloy card slot, as a part of the support structure, can ensure the stability and reliability of the entire rain shelter. The hot-dip galvanized card slot or the aluminum alloy card slot has good corrosion resistance, can resist the influence of various harsh climate conditions, and prolongs the service life. Using a plastic-coated clamping spring for fixing can not only closely fit the shed film, making the appearance of the rain shelter more beautiful, but also effectively reduce the fatigue damage of the shed film in the wind and rain. Therefore, using this method to fix the shed film has high practicability and economy. Description of the Drawings

[0031] A simple rain shelter for an umbrella-shaped steel frame column, comprising a number of shed bodies. Each shed body includes a hollow column 1. A sliding ring 2 is sleeved outside the column 1. A number of connecting rods 3 are hinged along the circumference of the sliding ring 2. One end of the connecting rod 3 away from the sliding ring 2 is hinged with a support rod 4. One end of the support rod 4 is hinged with the top end of the column 1. A shed film 5 is fixedly connected to the top of the support rod 4.

[0032] Combined with the attached Figure 2 As shown, a first shaft 6 is rotatably connected to the side wall of the column 1. The first shaft 6 penetrates through the side wall of the column 1. A gear 7 is coaxially and fixedly connected to the first shaft 6 by welding. A locking mechanism is provided on one side of the gear 7. A first rack 8 and a second rack 9 are respectively engaged on both sides of the gear 7. Both the first rack 8 and the second rack 9 are slidably matched with the inner wall of the column 1. A slider (not shown in the figure) is fixedly connected to the inner wall of the sliding ring 2 by welding. The slider penetrates through the side wall of the column 1 and extends into the column 1. A chute is provided on the side wall of the column 1. The slider is located in the chute and is slidably matched with the chute. The top of the first rack 8 is fixedly connected to the slider by welding.

[0033] The bottom of the second rack 9 is fixedly connected with a moving block 11. The moving block 11 is slidably matched with the inner wall of the column 1. A number of reinforcing rods 12 are hinged to the bottom of the moving block 11 through a hinge seat. A number of through holes 13 are provided at the bottom of the column 1. The reinforcing rods 12 respectively penetrate through the through holes 13 and are slidably matched with the through holes 13.

[0034] The specific implementation process is as follows: When using this rain shelter, insert the bottom end of the column 1 into the position where the rain shelter is required. The operator rotates the first shaft 6. When the first shaft 6 rotates, it drives the gear 7 to rotate. Since the first rack 8 and the second rack 9 are respectively engaged on both sides of the gear 7, at this time, the rotation of the gear 7 will drive the first rack 8 to move vertically upward, and the rotation of the gear 7 drives the second rack 9 to move vertically downward.

[0035] When the first rack 8 moves upward, it drives the slider to slide in the chute and simultaneously pushes the sliding ring 2 to move upward. When the sliding ring 2 moves upward, the connecting rod 3 supports the support rod 4 to form an open umbrella shape, and the shed film 5 is used for rain protection. At the same time, when the second rack 9 moves downward, it drives the moving block 11 to move downward. At this time, the reinforcing rods 12 pass through the through holes 13 and are obliquely inserted into the soil, thereby increasing the contact area between the bottom end of the column 1 and the soil, increasing the stability of the column 1, and making its wind resistance stronger. Using this insertion method can effectively save labor and material costs, and use the force to open the shed film 5 to deepen the foundation, saving manpower. Therefore, an umbrella-shaped structure design is adopted and fixed on the ground. No civil engineering is required during erection. The structure is simple, the installation is convenient and flexible, and the adaptability is strong.
