[0002] Agricultural greenhouses, also known as greenhouses, are facilities used for agricultural production. Their main function is to provide a suitable growth environment for crops, thereby improving the yield and quality of crops.

[0003] At present, when building an agricultural greenhouse, a tensioner is usually hung on the connecting pile of the greenhouse first, then the wire is fixed to the tensioner and tightened by the tensioner. Finally, the tightened wire is fixed to the connecting pile and the tensioner is removed. For example, a tensioner for building a shade shed or greenhouse disclosed in Chinese patent publication No. CN213839417U, however, cannot intuitively judge the tension of the wire during the tensioning process, which makes it impossible for the construction personnel to accurately control the tension of the wire. Utility Model Content

[0004] The purpose of the utility model is to provide a cable tensioner for greenhouse construction, which solves the current problem that when using a cable tensioner to tighten the wire, the tension of the wire cannot be intuitively judged, which leads to the construction personnel being unable to accurately control the tension of the wire.

[0012] The technical effects achieved by this utility model are:

[0013] The utility model provides a wire tensioner for greenhouse construction, which can move the elastic traction frame upward or downward by rotating the rotating bracket. At the same time, when the elastic traction frame moves upward, the wire fixed on the clamp can be tightened by the upward-moving elastic traction frame, and the distance between the hollow block and the connecting ring can be gradually reduced as the tension of the wire gradually increases. At this time, the tension of the wire can be intuitively judged by observing the scale at the intersection of the upper surface of the hollow block and the scale, thereby facilitating the user to control the tension of the wire.

[0014] The utility model provides a cable tensioner for greenhouse construction by providing positioning holes, ground nails and limiting blocks. When the ground nails pass through the positioning holes and are inserted into the soil, the positioning holes, the ground nails and the limiting blocks cooperate to prevent the cable tensioner from moving on the ground. Therefore, when the user rotates the turntable on the cable tensioner for greenhouse construction, the cable tensioner for greenhouse construction is not easy to move. At the same time, a pedal composed of a horizontal plate and an inclined plate is used so that the user can pull the ground nails out of the soil by stepping on the pedal.

[0030] Among them, the rotating bracket 4 includes a turntable 401, a threaded column 402, a first bearing 403, a connecting plate 404, a second bearing 405 and a connecting block 406. The bottom of the turntable 401 is fixedly connected to the top of the threaded column 402, and the surface of the threaded column 402 is rotatably connected to the inner wall of the connecting plate 404 through the first bearing 403. The upper surface of the left plate 2 and the upper surface of the right plate 3 are both fixedly connected to the bottom of the connecting plate 404. The surface of the threaded column 402 is rotatably connected to the inner wall of the connecting block 406 through the second bearing 405. The bottom of the connecting block 406 is fixedly connected to the upper surface of the base plate 1, and the surface of the threaded column 402 is threadedly connected to the inner wall of the elastic traction frame 5.

[0031] The elastic traction frame 5 includes a threaded cylinder 501, a hollow block 502, a first groove 503, a scale 504, a spring 505, a connecting ring 506, a second groove 507 and a connecting hole 508. The inner wall of the threaded cylinder 501 is threadedly connected to the surface of the threaded column 402. The surface of the threaded cylinder 501 fits with the inner wall of the hollow cylinder. The left and right sides of the hollow block 502 fit with the right side of the left plate 2 and the left side of the right plate 3 respectively. The first groove 503 is opened inside the hollow block 502. The inner wall of the first groove 503 fits with the surface of the scale 504. The scale 50 4 is fixedly connected to the front of the threaded barrel 501, the connecting hole 508 is provided inside the hollow block 502, the inner wall of the connecting hole 508 is fixedly connected to the surface of the traction rope 6, the second groove 507 is provided on the left side of the hollow block 502, the inner wall of the second groove 507 fits the surface of the traction rope 6, the upper and lower ends of the spring 505 are fixedly connected to the bottom of the hollow block 502 and the upper surface of the connecting ring 506 respectively, the inner wall of the connecting ring 506 is fixedly connected to the surface of the threaded barrel 501, and the elastic force of the spring 505 is greater than the sum of the gravity of the hollow block 502 and the traction rope 6.

[0032] It should be noted that, through the cooperation of the scale 504 and the first groove 503, the threaded barrel 501 cannot rotate in the hollow block 502, and through the cooperation of the left plate 2 and the right plate 3, the threaded barrel 501 cannot rotate on the threaded column 402. At this time, by rotating the threaded column 402, the hollow block 502 can be moved up or down with the cooperation of the threaded barrel 501 and the threaded column 402. At the same time, the hollow block 502 and the threaded barrel 501 cannot be separated by the connecting ring 506 and the spring 505, and the air suction is supported by the spring 505. When the wire fixed on the fixing clamp 8 is tightened, the distance between the hollow block 502 and the connecting ring 506 will gradually decrease as the tension of the wire gradually increases.

[0033] like Figures 1 to 10 As shown, a positioning hole 11 is opened inside the bottom plate 1 , and a ground nail 12 is provided on the inner wall of the positioning hole 11 , and a limiting block 13 is fixedly connected to the upper surface of the ground nail 12 .

[0034] A pedal 14 is fitted on the upper surface of the base plate 1 and the bottom of the limiting block 13 . A strip-shaped hole 15 is provided inside the pedal 14 , and the inner wall of the strip-shaped hole 15 fits with the surface of the ground nail 12 .

[0035] It should be noted that after the ground nail 12 passes through the positioning hole 11 and is inserted into the soil, the cooperation of the positioning hole 11, the ground nail 12 and the limit block 13 can make the greenhouse construction tensioner difficult to move on the ground. At the same time, through the pedal 14 composed of a horizontal plate and an inclined plate, the user can pull the ground nail 12 out of the soil by stepping on the pedal 14.

[0036] The working principle of the present invention is as follows: first, the hook 10 is connected to the pile, and the tensioner is placed in a suitable position; then, the pedal 14 is placed on the base plate 1, and the strip hole 15 on the pedal 14 is aligned with the positioning hole 11 on the base plate 1; then, the ground nail 12 is passed through the strip hole 15 and the positioning hole 11 in sequence and inserted into the soil; at this time, the tensioner for greenhouse construction can be fixed to the ground through the cooperation of the positioning hole 11, the ground nail 12 and the limit block 13.

[0037] Then, the wire and the traction wire are fixed together by the fixing clamp 8, and the turntable 401 is rotated to move the hollow block 502 upward with the cooperation of the threaded barrel 501 and the threaded column 402. At this time, the wire fixed on the clamp can be tightened by the upward moving hollow block 502, and the distance between the hollow block 502 and the connecting ring 506 gradually decreases as the tension of the wire gradually increases. Then, by observing the scale at the intersection of the upper surface of the hollow block 502 and the scale 504, the tension of the wire can be intuitively judged.

[0038] When the tension of the wire reaches an appropriate level, fix the wire on the connecting pile and separate the fixing clip 8 from the wire. Then, step on the pedal 14 to pull the ground spikes 12 out of the soil. When all the ground spikes 12 are pulled out of the soil, the tensioner can be removed.

[0039] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
