Description

Technical Field

[0001] This utility model belongs to the field of greenhouse planting technology, specifically a traction frame for planting greenhouse vegetable vines. Background Technology

[0002] Many cultivated vegetables are climbing vegetables, such as cucumbers, green beans, and tomatoes. To improve the growth quality of climbing vegetables and expand their growing space, it is usually necessary to build a support structure using wooden poles or bamboo poles. However, these support materials have a short lifespan due to long-term exposure to wind, rain, and sun. This problem can be solved by setting up a special climbing frame.

[0003] The trellis for growing vine vegetables is a device erected around vine plants to facilitate their climbing. During use, it needs to support the branches at different stages of the vine's growth, meaning the height of the trellis needs to be adjusted constantly. Similarly, the height needs to be adjusted for different vines. However, existing height adjustment mechanisms for vine trellises are inadequate, lacking suitable safety features during adjustment. This results in significant resistance during adjustment due to the trellis itself and the traction of the climbing vines, easily leading to accidental loosening and dropping to the lowest support height, damaging the supporting vines, or even causing fruit to fall and injure people. Therefore, it is necessary to develop a trellis for greenhouse vegetable vine cultivation to address the shortcomings of existing technologies. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6As shown, this utility model provides a traction frame for planting greenhouse vegetable vines, including a fixed support component 1, a mounting base 2 connected to the bottom of the fixed support component 1, a traction frame 3 located above the mounting base 2 on both sides of the fixed support component 1, a locking connection component 4 sleeved inside the fixed support component 1, the upper end of the locking connection component 4 extending to the top of the fixed support component 1 and connected to the top of the facing surfaces of the two traction frames 3, and a control component 5 inside the locking connection component 4.

[0025] The control component 5 includes a linkage rod 51 movably fitted inside the locking connection component 4. The lower end of the linkage rod 51 extends to the lower end of the locking connection component 4. The lower end of the linkage rod 51 pushes the lower end of the locking connection component 4 to lock with the fixed support component 1. The upper end of the locking connection component 4 has an adapter cavity 54. The upper end of the linkage rod 51 extends into the adapter cavity 54 and is fixedly connected to a second sliding shaft 55. The bottom of the second sliding shaft 55 is a smooth slope. Two left and right sliding rods 56 are attached to the slope of the bottom of the second sliding shaft 55. The distal ends of the two sliding rods 56 extend to the lock. The locking connection component 4 is externally and fixedly connected to a pressing block 57 located above the fixed support component 1. The outer surface of the slide rod 56 is provided with a fourth spring 58 that abuts against the locking connection component 4 and the pressing block 57. Due to the setting of the control component 5, with the cooperation of the locking connection component 4, it is convenient for the operator to operate. It can be pressed at any time to unlock and facilitate lifting and lowering. At the same time, it can be released at any time to lock immediately, so as to lock in time to fix the height of the traction frame 3 or avoid damage from continuous falling of the traction frame 3.

[0026] The fixed support assembly 1 includes a support sleeve 11 fixedly connected to the top of the mounting base 2. The support sleeve 11 has two locking plates 12 inside. The support sleeve 11 facilitates the installation and adjustment of the locking connection assembly 4 and the control assembly 5. With the cooperation of the locking plates 12, the locking connection assembly 4 can automatically connect to it, thereby achieving automatic locking to ensure the purpose of adjustment and safety.

[0027] The traction frame 3 is equipped with a traction beam 7 inside, and a stabilizing sleeve 6 is fixedly connected between the bottom of the two opposing surfaces of the traction frame 3. The stabilizing sleeve 6 is slidably sleeved on the outer surface of the support sleeve 11. Due to the setting of the traction beam 7, the traction strength and effect of the traction frame 3 can be increased, while the setting of the stabilizing sleeve 6 can improve the stability of the lifting and traction support of the traction frame 3 with the cooperation of the upper end of the locking connection component 4.

[0028] The locking connection assembly 4 includes a locking block 41 that is slidably installed inside the support sleeve 11 and between the two locking plates 12. A support rod 42 is fixedly connected to the top of the locking block 41. The upper end of the support rod 42 extends above the fixed support assembly 1 and is fixedly connected to the top of the traction frame 3. The control assembly 5 is located inside the support rod 42.

[0029] The locking block 41 has a slot 43 in the middle and a sliding groove 44 on both the left and right sides. The near ends of the two sliding grooves 44 are connected to the left and right sides of the slot 43, and the far ends of the two sliding grooves 44 correspond to the two locking plates 12. The slots 43 and sliding grooves 44 are provided, which also facilitates the setting of the first spring 46. This ensures the stable sliding of the slider 45 and the locking plate 47, and also facilitates the lower end of the control component 5 to push the inclined surface of the two sliders 45 facing each other.

[0030] The lower end of the linkage rod 51 passes through the support rod 42 and extends into the interior of the slot 43, where it is fixedly connected to the first sliding shaft 52. A third spring 53 is provided on the outside of the linkage rod 51. The upper end of the third spring 53 abuts against the top of the inner cavity of the slot 43, and the lower end of the third spring 53 abuts against the top of the first sliding shaft 52. Due to the provision of the third spring 53, under the action of its elastic restoring force, the first sliding shaft 52 can be pushed down, and then, under the restriction of the slot 43, the two sliders 45 are pushed away from each other, and the second spring 48 is compressed so that the two locking plates 47 can engage with the two locking plates 12 in time, achieving the effect of timely locking.

[0031] The slot 43 has two sliders 45 slidingly engaged inside. The upper ends of the opposing surfaces of the two sliders 45 are smooth slopes and are in contact with the outer surface of the first sliding shaft 52.

[0032] A first spring 46 is abutting between the back faces of the two sliders 45 and the two sides of the inner cavity of the slot 43. A second spring 48 is connected to the back faces of the two sliders 45. The other end of the second spring 48 extends into the interior of the slide groove 44 and is connected to a locking plate 47. The back faces of the two locking plates 47 respectively mesh with the facing surfaces of the two locking plates 12.

[0033] Working principle and usage process of this utility model:

[0034] The device is fixed to the vicinity of the vines inside the greenhouse using mounting base 2. Then, according to the required traction height, the overall height of the traction frame 3, locking connection assembly 4, and fixed support assembly 1 is adjusted. Specifically, the two pressing blocks 57 are pressed down so that, under the constraint of support rod 42, the two fourth springs 58 are compressed, and the two sliding rods 56 are pushed closer to each other. Under the constraint of adapter cavity 54, the near ends of the two sliding rods 56 push the smooth inclined surface at the bottom of the second sliding shaft 55, causing the second sliding shaft 55 to move upward under the constraint of adapter cavity 54. The upward movement of the second sliding shaft 55... The first sliding shaft 52 can be moved upward by the linkage rod 51, and the third spring 53 is compressed under the restriction of the slot 43, which in turn moves the first sliding shaft 52 upward. Then, under the elastic restoring force of the first spring 46, the two sliders 45 are brought closer to each other, and the two locking plates 47 are brought closer to each other by the second spring 48, so that the two locking plates 47 are disengaged from the corresponding locking plates 12. At this time, the support rod 42 can be moved up and down, so that it moves relative to the support sleeve 11, and with the cooperation of the stabilizing sleeve 6, the traction frame 3 is raised and lowered, thereby changing the height of the traction frame 3.

[0035] In the event of adjustment completion or unexpected circumstances, the operator will release the two pressing blocks 57. Under the elastic restoring force of the fourth spring 58, the two sliding rods 56 and the fourth spring 58 will reset. At the same time, under the elastic restoring force of the third spring 53, the first sliding shaft 52 will be pushed, causing the linkage rod 51 and the second sliding shaft 55 to move down. This will push the two sliders 45 away from each other through the first sliding shaft 52 and compress the first spring 46. Simultaneously, the second spring 48 will push the two locking plates 47 away from each other until the two locking plates 47 engage with the corresponding locking plates 12, thereby ensuring timely locking and preventing the traction frame 3 from falling unexpectedly.
