Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse clamps, in particular to a film clamp for a greenhouse. Background Art

[0002] Agricultural greenhouses (also known as greenhouses) are facilities used to grow crops. They can provide constant temperature, humidity and light conditions, which help increase crop yields and improve quality. Agricultural greenhouses can be used to grow crops without seasonal and climatic restrictions, and are suitable for the growth and cultivation of various crops. When in use, especially in summer, it is often necessary to pull open a portion of the film on the top of the greenhouse to enhance the air exchange between the inside of the greenhouse and the outside world.

[0003] Since the top of the greenhouse is high, for the convenience of use, people often choose to clip ordinary clips on the edge of the top greenhouse film, and then tie a rope to the clip, and extend the rope to the bottom of the greenhouse for the convenience of users to use, or manually go to the roof to cover the film. However, since the force surface of the ordinary clip is basically concentrated at one point, it is easy to tear the film when using the ordinary clip to pull it, or the film is easy to fall off, which is very inconvenient whether using ordinary clips or manually covering. Utility Model Content

[0004] In view of the above problems, the utility model provides a greenhouse film clamp to solve the problem in the prior art that ordinary clips easily tear the film when pulling the film, which is very inconvenient whether manually lifting the cover or using ordinary clips.

[0005] The utility model is realized by using the following technical scheme: a film clamp for greenhouses, comprising a plate clamp, wherein the plate clamp comprises an upper clamping plate and a lower clamping plate arranged up and down, wherein the upper clamping plate and the lower clamping plate are connected by an elastic connecting portion at one end thereof to form an elastic clamping structure that can be opened and closed; the film clamp also comprises a locking mechanism capable of clamping the upper clamping plate and the lower clamping plate.

[0006] Through the design of the plate clamp, the force between the clamp and the film is changed from point force to surface force, thereby preventing the film from being torn during the traction process. Through the installation of the locking mechanism, the plate clamp can clamp the film more securely and prevent the film from detaching from the plate clamp, which would affect normal use.

[0007] Preferably, the locking mechanism includes a limiting through hole that passes through the plate clamp, a puncture portion that can pass through the limiting through hole and abut against the lower clamping plate, and a positioning mechanism that can fix the puncture portion. Through the cooperation of the positioning mechanism and the puncture portion, the lower clamping plate is close to the upper clamping plate, which is more stable to use. In addition, this method has a simpler structure and is more convenient to use.

[0008] Preferably, the positioning mechanism comprises an elastic part connected to the end of the puncture part away from the lower clamping plate and a limit plate for clamping the elastic part, and the limit plate is fixedly mounted on the upper clamping plate; the puncture part is a "V"-shaped rod structure. The design of the elastic part and the limit plate makes the positioning mechanism simpler, and the unlocking of the locking mechanism only requires the elastic part to be separated from the limit plate, which is easy to operate.

[0009] Preferably, the elastic part, the puncture part, the limiting through hole and the limiting plate are each provided with two, which are respectively located at the front and rear sides of the plate clamp. Through the above design, the film clamped by the plate clamp can be subjected to more uniform force, further increasing the stability of the device.

[0010] Preferably, the right end of the elastic part is also equipped with a support part extending upward, and the top of the support part extends upward to form a fixing part. Through the design of the fixing part, the user can bend the fixing part when using it, and can more conveniently bend the elastic part to the limit plate, so that the device is more stable when in use.

[0011] Preferably, an arc-shaped connecting part is fixedly installed between the two fixing parts, and the two ends of the arc-shaped connecting part are respectively fixedly connected to the top ends of the two fixing parts, and the arc-shaped connecting part is in an upward arc shape. By setting the arc-shaped connecting part, the entire locking mechanism becomes a whole and is more stable.

[0012] Preferably, the two puncture parts, the elastic part, the support part, the fixing part and the arc-shaped connecting part are a metal strip bent multiple times. The stability of the locking mechanism in the device is further enhanced through the integrated design.

[0013] Preferably, the lower clamping plate is further provided with a downward arc-shaped protrusion, and a limit groove is formed at the arc-shaped protrusion of the lower clamping plate. The arc-shaped protrusion is designed so that it can be used in conjunction with a traction column or a rib to further prevent the film from falling off the clamp after installation.

[0014] Preferably, a traction through hole for installing a traction rope is further provided on the left side of the plate clip. Through the design of the traction through hole, the plate clip can be used in conjunction with the traction rope, so that the user can pull the plate clip more conveniently.

[0015] Preferably, the upper clamping plate, the lower clamping plate, the elastic connection part and the limit plate are integrally formed. The integrally formed design makes the plate clamping structure in the device more stable.

[0016] In summary, the beneficial effects of the present invention are:

[0017] 1. Through the combination of the plate clamp and the locking mechanism, the force area between the clamp and the film is changed from point force to surface force, thereby better avoiding the film being torn due to the traction process. At the same time, compared with manually lifting the film on the top of the greenhouse, this method can be achieved inside the greenhouse, which is more convenient to operate.

[0018] 2. The locking mechanism composed of the elastic part and the puncture part is easy to install. When disassembling, it is only necessary to separate the elastic part from the position of the limit plate, and then pull out the entire locking mechanism. It has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0028] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0029] Combination Figure 1 , Figure 2 The utility model is a film clamp for greenhouses, which includes a plate clamp, which includes an upper clamping plate 5 and a lower clamping plate 8 arranged up and down, and the upper clamping plate 5 and the lower clamping plate 8 are connected by an elastic connecting portion 7 at one end thereof to form an elastic clamping structure that can be opened and closed. The upper clamping plate 5, the lower clamping plate 8 and the elastic connecting portion 7 are designed as an integral molding; the device also includes a locking mechanism that can clamp the upper clamping plate 5 and the lower clamping plate 8.

[0030] When the film 13 is clamped, if the film 13 is clamped only by the plate clamp, the clamping force is insufficient and the film 13 falls off, so a locking mechanism is required to clamp the upper clamping plate 5 and the lower clamping plate 8. The locking mechanism in the present application document can be in any form, including clamping the upper clamping plate 5 and the lower clamping plate 8 by the combination of bolts and nuts.

[0031] In this embodiment, the locking mechanism includes a limiting through hole 11 penetrating the plate clamp, a puncture portion 10 that can pass through the limiting through hole 11 and abut against the lower clamping plate 8, and a positioning mechanism that can fix the puncture portion 10. The shape of the locking mechanism is as follows: Figures 1 to 3 As shown. The positioning mechanism includes an elastic part 3 connected to the end of the puncture part 10 away from the lower splint 8 and a limit plate 4 for clamping the elastic part 3, and the limit plate 4 is fixedly mounted on the upper splint 5. When the puncture part 10 passes through the limit through hole 11 and bends the elastic part 3 to the position of the limit plate 4, the puncture part 10 can firmly press the lower splint 8 against the lower surface of the upper splint 5. The puncture part 10 is a "V"-shaped rod structure, and the angle between the two sides of the puncture part 10 can be an acute angle, a right angle, and an obtuse angle. The angle of the puncture part 10 is different, and the degree of bending of the elastic part 3 required for the puncture part 10 to press against the lower splint 8 is also different. When the two sides of the puncture part 10 are obtuse angles, the degree of bending required for the elastic part 3 is the smallest, so the angle between the puncture parts 10 in this embodiment is an obtuse angle. The limiting plate 4 is equivalent to being cut out from the surface of the upper splint 5, and then the cut-out part is bent into an "L" shape, and the elastic part 3 is bent to the bottom of the limiting plate 4 to prevent the puncture part 10 from rebounding after being bent horizontally, thereby ensuring that the puncture part 10 can be firmly against the lower splint 8.

[0032] like Figure 2 , Figure 3As shown, the elastic part 3, the puncture part 10, the limiting through hole 11, and the limiting plate 4 are each provided with two, which are respectively located at the front and rear sides of the plate clamp. Through the design of the two sets of elastic parts 3 and the puncture part 10, the device can be more stable when clamping the film 13 and dragging it to move. The right end of the elastic part 3 is also equipped with an upwardly extending support part 12, and the top of the support part 12 extends upward to form a fixed part 2. An arc-shaped connecting part 1 is also fixedly installed between the two fixed parts 2. The two ends of the arc-shaped connecting part 1 are respectively fixedly connected to the tops of the two fixed parts 2, and the arc-shaped connecting part 1 is in an upward arc shape.

[0033] The design of the fixing portion 2 and the supporting portion 12 can make it more convenient for the user to bend the elastic portion 3. When the puncture portion 10 is inserted into the bottom of the plate clip along the limiting through hole 11, the fixing portion 2 is then bent counterclockwise to fix the elastic portion 3 at the bottom of the limiting plate 4. The design of the arc-shaped connecting portion 1 transforms the two fixing portions 2 from being independent into a whole. When in use, it only needs to be bent once, without the need to bend the two fixing portions 2 separately, making the device more convenient. In addition, the design of the arc-shaped connecting portion 1 turning it into a whole provides support between the two elastic portions 3, thereby preventing the two elastic portions 3 from shifting inwards of the elastic portions 3 on both sides after installation, preventing the elastic portions 3 from falling off, and making the device more stable.

[0034] like Figure 3 As shown, the two puncture parts 10, the elastic part 3, the support part 12, the fixing part 2 and the arc-shaped connecting part 1 are a metal strip bent multiple times, that is, integrally formed. Through this design, the structure of the locking mechanism of the device is simpler, and the simple structure also means that the device can be more stable when in use.

[0035] like Figure 2 , Figures 4 to 6 As shown, the lower clamping plate 8 is also provided with a downward arc-shaped protrusion 9, and a limiting groove is formed at the arc-shaped protrusion 9 of the lower clamping plate 8. By winding the film 13 on the traction column 14, and then placing the traction column 14 at the limiting groove, when the locking mechanism clamps the plate clamp and pulls the plate clamp, the film 13 will have a movement tendency to break away from the plate clamp, but because the film 13 is wound on the traction column 14, and the diameter of the traction column 14 is larger than the gap between the upper clamping plate 5 and the lower clamping plate 8, it cannot break away from the plate clamp, thereby making the device more stable when pulled.

[0036] The left side of the plate clamp is also provided with a traction through hole 6 for installing a traction rope. By passing the traction through hole 6 and being tied to the plate clamp, the traction rope can then be pulled to achieve the effect of pulling the plate clamp.

[0037] The operating principle of the device is as follows: first, fold the edge of the film 13, insert a traction column 14 at the folded part, that is, the film 13 is sleeved on the traction column 14, and then the traction column 14 and the film 13 are pushed into the plate clamp along the gap between the upper clamp 5 and the right end of the lower clamp 8, until the traction column 14 is at the arc-shaped protrusion 9. Since the locking mechanism is not installed on the plate clamp at this time, the plate clamp can also be moved to increase the gap between the upper clamp 5 and the lower clamp 8. When the film 13 is installed, the puncture part 10 of the locking mechanism is inserted into the limiting through hole 11, and the puncture part 10 punctures the film 13 and extends into the bottom of the lower clamp 8, and then the fixing part 2 or the elastic part 3 is moved so that the elastic part 3 is placed at the bottom of the limiting plate 4, and the plate clamp can firmly clamp the film 13. Finally, the traction rope is tied to the plate clamp. When the greenhouse needs to be ventilated, the traction rope can be pulled to drive the film 13 to move and adjust its position, so that a gap is formed between the films 13 of the greenhouse for ventilation.

[0038] In addition, the device can also be used as a fixing clamp, with the same result as above. It is only necessary to clamp the plate clamp on the ribs used to support the film 13, and make the ribs be located at the position of the arc-shaped protrusion 9. Then the locking mechanism is installed to fix the film 13. Since the plate clamp plays a fixing role at this time, there is no need to install a traction rope at this time.

[0039] In summary, the utility model of a greenhouse film clamp combines the plate clamp with the locking mechanism, so that the force area between the clamp and the film 13 changes from point force to surface force, thereby better avoiding the film 13 being torn due to the traction process. At the same time, compared with manually lifting the film 13 on the top of the greenhouse, this method can be implemented inside the greenhouse, which is more convenient to operate. The locking mechanism composed of the elastic part 3 and the puncture part 10 is simple to install. When disassembling, it is only necessary to make the elastic part 3 detach from the position of the limit plate 4, and then pull out the entire locking mechanism. It has a simple structure and is easy to operate.

[0040] 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 substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
