[0002] In the prior art, there is a greenhouse frame, which mainly comprises a frame body (wood frame or steel frame) and a supporting steel wire. The supporting steel wire is transversely arranged across the frame body, and the frame body and the supporting steel wire are fixed by a short steel wire at the intersection, which is defined as a binding wire. Referring to Figure 14 The two ends of the binding wire are wound around the supporting steel wire to fix the frame body and the supporting steel wire.

Therefore, the drawings and description are essentially illustrative, and are not intended to limit the protection scope of the claims.

[0031] Embodiment one:

[0032] As Figures 1 to 9As shown, the steel wire bundling device for greenhouse includes a cross-wire rotating sleeve 10, a cross-wire opening 20 is arranged on the surface of the cross-wire rotating sleeve 10 in the axial direction, the cross-wire opening 20 extends to the center of the cross-wire rotating sleeve 10 in the radial direction from the outer circumferential surface of the cross-wire rotating sleeve 10, a wire binding pressure column 30 is arranged on the front end surface of the cross-wire rotating sleeve 10, a supporting ring seat 41 is arranged on the rear end surface of the cross-wire rotating sleeve 10, an operating handle 50 is arranged on the outer periphery of the supporting ring seat 41, the supporting ring seat 41 is coaxially arranged with the cross-wire rotating sleeve 10, a ring seat opening 70 corresponding to the cross-wire opening 20 is arranged on the supporting ring seat 41, a sleeve driving mechanism 40 is further arranged between the supporting ring seat 41 and the cross-wire rotating sleeve 20, and a anti-falling elastic lock 60 is arranged on the middle part of the cross-wire rotating sleeve 10 to block the cross-wire opening 20. The cross-wire opening 20 and the ring seat opening 70 are arranged to enable the device to cross the supporting steel wire A, and to avoid the device from falling off the supporting steel wire A during the rotation operation. Therefore, the anti-falling elastic lock 60 is arranged at the cross-wire opening 20. On one hand, the anti-falling elastic lock 60 can pass through the supporting steel wire A to achieve the purpose of crossing, and on the other hand, the anti-falling elastic lock 60 can lock the supporting steel wire A inside to achieve the purpose of anti-falling. The sleeve driving mechanism 40 can realize the one-way rotation of the cross-wire rotating sleeve 10, reduce the hand range of the operator, and reduce the operation difficulty.

[0033] Referring to Figure 1 and Figure 2 , the cross-wire opening 20 includes a cross-wire shaft hole 21 arranged at the center of the cross-wire rotating sleeve 10, and a cross-wire channel 22 arranged on one side of the cross-wire shaft hole 21, the cross-wire channel 22 extends in the radial direction towards the outer circumferential surface of the cross-wire rotating sleeve 10, and the width of the cross-wire channel 22 is smaller than the diameter of the cross-wire shaft hole 21.

[0034] Referring to Figure 1 and Figure 5 , two elastic lock limiting grooves 23 are arranged on the two surfaces of the cross-wire channel 22, respectively, the width between the two elastic lock limiting grooves 23 is greater than the width of the cross-wire channel 22 and smaller than the diameter of the cross-wire shaft hole 21, the front end of the anti-falling elastic lock 60 abuts against the front end surface of the elastic lock limiting groove 23, and the rear end of the anti-falling elastic lock 60 abuts against the rear end surface of the elastic lock limiting groove 23. The elastic lock limiting groove 23 can be processed by a milling cutter.

[0035] The anti-off elastic lock piece 60 is an integral elastic sheet with elastic deformation sheet structure. The anti-off elastic lock piece 60 includes an arc-shaped wrapping body 61 located at the center of the cross-wire rotating sleeve 10, the outer surface of the arc-shaped wrapping body 61 contacts the surface of the cross-wire shaft hole 21, the upper two ends of the arc-shaped wrapping body 61 are respectively provided with V-shaped bodies 62, the two V-shaped bodies 62 are located in the cross-wire channel 22, the tips of the two V-shaped bodies 62 are oppositely arranged and an opening and closing channel 63 is formed between the tips, the opening and closing channel 63 is squeezed open, the width is greater than the diameter of the supporting steel wire, which is beneficial to the passing of the supporting steel wire, the upper ends of the two V-shaped bodies 62 extend upward and are provided with lock piece limiting bodies 64 which are limitedly installed in the elastic lock piece limiting groove 23, the upper end of the lock piece limiting body 64 extends out of the cross-wire opening 20 and is bent to the side and abuts against the outer circumferential surface of the cross-wire rotating sleeve 10.

[0036] The arc-shaped wrapping body 61 is provided in a structure corresponding to the cross-wire shaft hole 21, the outer surface of the arc-shaped wrapping body 61 contacts and supports on the cross-wire shaft hole 21, because the diameter of the cross-wire shaft hole 21 is greater than the width of the cross-wire channel 22, when the arc-shaped wrapping body 61 is located in the cross-wire shaft hole 21, the arc-shaped wrapping body 61 is radially limited by the cross-wire shaft hole 21, and the arc-shaped wrapping body 61 cannot slip out along the cross-wire channel 22; because the surface of the lock piece limiting body 64 contacts the surface of the elastic lock piece limiting groove, and the front end of the lock piece limiting body 64 abuts against the front end surface of the elastic lock piece limiting groove 23, and the rear end of the lock piece limiting body 64 abuts against the rear end surface of the elastic lock piece limiting groove 23, the lock piece limiting body 64 is axially limited, so that the anti-off elastic lock piece 60 cannot slip out in the axial direction of the cross-wire rotating sleeve 10.

[0037] When installing, the anti-off elastic lock 60 is inserted into the cross-wire opening 20 from the front end of the cross-wire rotating sleeve 10, the arc-shaped wrapper 61 is placed in the cross-wire shaft hole 21, and when the anti-off elastic lock 60 gradually penetrates, the lock limiting body 64 stops after entering the elastic lock limiting groove 23, the front end and the rear end are respectively abutted against the front end and the rear end of the elastic lock limiting groove 23, the V-shaped body 62 is located in the cross-wire channel 22, and the lock limiting body 64 is tightly pressed at the elastic lock limiting groove 23 to support the V-shaped body 62, that is, the quick installation and limiting of the anti-off elastic lock 60 are completed, at this time, the opening and closing channel 63 between the two V-shaped bodies 62 is in a closed state, and the width of the opening and closing channel 63 is obviously smaller than the diameter of the support steel wire A. When the cross-wire is needed, the support steel wire A is aligned between the two V-shaped bodies 62, and then pressed, at this time, the support steel wire A deforms the V-shaped body 62, extrudes and enlarges the width of the opening and closing channel 63, and then smoothly extrudes into the middle part of the arc-shaped wrapper 61. When the V-shaped body 62 is no longer extruded and recovers deformation, the opening and closing channel 63 is closed. When the cross-wire rotating sleeve 10 is rotated, the extrusion of the V-shaped body 62 is small at this time, the opening and closing channel 63 will always remain closed, which can prevent the cross-wire rotating sleeve 10 from being separated from the support steel wire A. When the binding wire is completed, the cross-wire rotating sleeve 10 is pulled towards the cross-wire opening 20, the support steel wire A extrudes the V-shaped body 62, the opening and closing channel 63 is opened, and the cross-wire rotating sleeve 10 is separated from the support steel wire A. The length of the anti-off elastic lock 60 is at least 1 / 3 of the length of the cross-wire opening 20, which can achieve a better anti-off supporting effect.

[0038] The sleeve driving mechanism 40 comprises a support ring seat 41 sleeved on the outer circumferential surface of the cross-wire rotating sleeve 10, at least three pawls 42 are arranged on the outer end surface of the cross-wire rotating sleeve 10, springs 43 are arranged between the pawls 42 and the cross-wire rotating sleeve 10, and the inner periphery of the support ring seat 41 is provided with ratchet teeth 44 matched with the pawls 42. The matching of the pawls 42 and the ratchet teeth 44 makes the cross-wire rotating sleeve 10 only rotate in a single direction, as shown in Figure 4When the operating handle 50 is pulled clockwise, the support ring seat 41 rotates clockwise around the cross-wire rotating sleeve 10, but the cross-wire rotating sleeve 10 does not rotate, when the operating handle 50 is pulled counterclockwise, the pawl 42 is engaged on the ratchet tooth 44, the support ring seat 41 rotates counterclockwise together with the cross-wire rotating sleeve 10. In this embodiment, since the support ring seat 41 is provided with the ring seat opening 70, in order to avoid affecting the cooperation of the pawl 42 and the ratchet tooth 44 at the ring seat opening 70, at least three pawls 42 are provided, when one of the pawls 42 is at the ring seat opening 70, the other two pawls 42 can still ensure the normal operation of the ratchet wheel.

[0039] Referring to Figure 2 , the outer end surface of the support ring seat is further provided with a ring seat end cover, the ring seat end cover is installed on the outer end surface of the support ring seat by screws, the ring seat end cover clamps the pawl and the spring inside, protects the internal structure, the ring seat end cover is provided with an end cover opening corresponding to the cross-wire opening, the shape of the end cover opening is consistent with that of the cross-wire opening, and the end cover opening can also be used to pass through the support steel wire A.

[0040] The end of the cross-wire rotating sleeve 10 is provided with a ring seat mounting portion 45, one end of the support ring seat 41 is provided with a ring seat sleeve 46 sleeved on the ring seat mounting portion 45, the inner diameter of the ring seat sleeve 46 is slightly larger than that of the ring seat mounting portion 45, the end surface of the ring seat sleeve 46 abuts against the limiting shoulder 47 of the cross-wire rotating sleeve 10, the outer periphery of the ring seat mounting portion 45 is further provided with a limiting groove 48, the surface of the ring seat sleeve 46 is provided with a limiting screw hole, and a limiting screw column 49 is threadedly installed at the limiting screw hole. In this embodiment, a plurality of limiting screw columns 49 can be provided on the outer periphery of the ring seat sleeve 46, the inner end of the limiting screw column 49 extends into the limiting groove 48 to limit the axial movement of the support ring seat 41. Since the cross-wire rotating sleeve 10 can rotate relative to the support ring seat 41, and in order to ensure that the support ring seat 41 can be stably connected to the cross-wire rotating sleeve 10, the limiting is performed by the limiting screw column 49, which can avoid the sliding off of the ring seat sleeve 46 and does not affect the relative rotation.

[0041] The end of the cross-wire rotating sleeve 10 is provided with a guide sliding rail 31, the guide sliding rail 31 is inclinedly arranged, the wire binding pressing column 30 is slidingly installed along the guide sliding rail 31, and the distance between the wire binding pressing column 30 and the center of the cross-wire rotating sleeve 10 gradually decreases from outside to inside, referring to Figure 11 When the cross-wire rotating sleeve 10 rotates clockwise, the wire binding pressing column 30 slidingly approaches the center of the cross-wire rotating sleeve 10 in the counterclockwise direction along the guide sliding rail 31 from outside to inside.

[0042] The wire binding pressure column 30 comprises a pressure column sliding block 32 sliding along the guide sliding rail 31, the surface of the pressure column sliding block 32 is fixed with a connecting column 33, the connecting column 33 can be fixed on the pressure column sliding block 32 by welding, the outer surface of the connecting column 33 is sleeved with a column sleeve 34, the outer end of the connecting column 33 is provided with a sleeve stop head 37 resisting the column sleeve 34, the surface of the column sleeve 34 is provided with an arc-shaped pressure groove 35, the connecting column 33 and the sleeve stop head 37 can be threaded columns which are fixed on the pressure column sliding block 32 by threading, of course, they can also be directly welded on the pressure column sliding block 32.

[0043] The guide sliding rail 31 is a T-shaped groove, the pressure column sliding block 32 is a T-shaped block matched with the T-shaped groove, the surface of the T-shaped groove is mounted with a limiting stop block 36 used for abutting against the T-shaped block, the limiting stop block 36 is screwed in the T-shaped groove, when the T-shaped block contacts the limiting stop block 36, the distance between the wire binding pressure column and the center of the wire crossing rotating sleeve is minimum. Here, the limiting stop block 36 plays a limiting role, which is used for limiting the limit position of the upward sliding of the pressure column sliding block. In this embodiment, a plurality of threaded holes for mounting the limiting stop block 36 are arranged in the T-shaped groove, which can be used to meet different use requirements, see Figure 3 Two threaded holes are shown, when the limiting stop block 36 is mounted in the uppermost threaded hole, at this time, when the wire binding pressure column 30 slides along the guide sliding rail, the distance between the wire binding pressure column and the center of the wire crossing rotating sleeve is minimum when it slides to the limiting stop block 36.

[0044] The wire binding pressure column 30 is used for driving the wire binding to rotate along with the wire crossing rotating sleeve 10, so that the wire binding can be wound on the supporting steel wire A. In order to make the wire binding achieve the effect of tight binding, the wire binding pressure column 30 needs to be as close as possible to the center of the wire crossing rotating sleeve 10. In order to adapt to the supporting steel wire A and the wire binding B with different thicknesses, the distance between the wire binding pressure column 30 and the center of the wire crossing rotating sleeve 10 needs to be adjustable in size. Therefore, the device is provided with a guide sliding rail 31, the wire binding pressure column 30 can slide along the guide sliding rail 31 to increase or decrease the distance from the center of the wire crossing rotating sleeve 10. When the wire binding pressure column 30 slides to one end of the guide sliding rail 31 (the position where the T-shaped block contacts the limiting stop block 36 in the middle), Figure 11 the distance between the center of the wire crossing rotating sleeve 10 and the wire binding pressure column 30 is minimum. When the wire binding pressure column 30 slides to the other end (the lower end) of the guide sliding rail 31, Figure 11 the distance between the center of the wire crossing rotating sleeve 10 and the wire binding pressure column 30 is maximum, see Figure 11As shown, the distance between the wire binding pressure column 30 and the center of the cross-wire rotating sleeve 10 gradually decreases when the wire binding pressure column 30 slides upward, and the wire binding pressure column 30 cannot continue to slide when it abuts against the limiting stopper 36, at which time the distance between the wire binding pressure column 30 and the center of the cross-wire rotating sleeve 10 is the smallest.

[0045] Referring to Figure 11 When the cross-wire rotating sleeve 10 rotates clockwise, the free end of the wire binding B extrudes the wire binding pressure column 30 outward, so that the wire binding pressure column 30 slides upward along the guide rail 31, and the wire binding pressure column 30 gradually approaches the center of the cross-wire rotating sleeve 10. When the sliding stops, the wire binding pressure column 30 always remains in this position as the cross-wire rotating sleeve 10 continues to rotate, so that the wire binding B can be tightly pressed against the support steel wire A. When the wire binding is completely wound, the wire binding pressure column 30 is no longer extruded by the wire binding, so the wire binding pressure column 30 is free and separated from the wire binding. Since the wire binding pressure column 30 is to be pressed against the surface of the wire binding B when the cross-wire rotating sleeve 10 rotates, in order to reduce the friction between the wire binding B and the wire binding pressure column 30, a column sleeve 34 is additionally provided on the outer surface of the connecting column 33. When the wire binding pressure column 30 presses the wire binding B, the wire binding B slides relative to the wire binding pressure column 30, at which time the column sleeve 34 can rotate around the wire binding pressure column 30, so as to relieve the resistance of the wire binding acting on the wire binding pressure column 30. The column sleeve 34 is limitedly installed by the sleeve stopper 37, and the column sleeve 34 can slide along the axis direction of the connecting column 33 and also freely rotate around the connecting column 33, so as to meet the use requirements. In use, when the wire binding B presses the column sleeve 34 tightly against the sleeve stopper 37, since the device is a small tool, the winding is not very strict, and the rear part can appropriately slightly sway, so that the column sleeve 34 can be released from the sleeve stopper 37, without affecting the use. In order to make the wire binding B move better according to the ideal direction, an arc-shaped pressing groove 35 is additionally provided on the surface of the column sleeve 34, so that the wire binding B slides along the direction of the arc-shaped pressing groove 35, so as to limit the free end of the wire binding B.

[0046] The working principle of the embodiment is as follows:

[0047] Before winding, one end of the wire binding B is first pre-bent on the support steel wire A, and then the device is passed through the opening and closing channel 63 to pass the support steel wire A into the arc-shaped wrapping body 61, so that the cross-wire rotating sleeve 10 straddles and rides on the support steel wire A, as shown in Figure 11The free end of the binding wire B is then placed on the inner side of the binding wire pressing column 30 so that the binding wire B can be bound clockwise on the supporting steel wire A; when the operating handle 50 is lifted counterclockwise, the supporting ring seat 41 rotates counterclockwise, at this time the cross-wire rotating sleeve 10 does not rotate (the hand holding the cross-wire rotating sleeve 10 can be released), then the operating handle 50 is pressed clockwise, the hand holding the cross-wire rotating sleeve 10 is released, at this time the supporting ring seat 41 rotates clockwise with the cross-wire rotating sleeve 10, the state of the binding wire pressing column 30 is shown in Figure 11 , and is pushed by the friction of the binding wire B, and slides towards the center of the cross-wire rotating sleeve 10, and tightens the binding wire B so that the binding wire B is as close as possible to the surface of the supporting steel wire A, the operating handle 50 is repeatedly lifted and pressed, so that the binding wire pressing column 30 rotates clockwise with the cross-wire rotating sleeve 10 all the time, and the binding wire B is wound on the surface of the supporting steel wire A in the state of Figure 11 ; when the binding wire is completely wound, referring to Figure 12 , at this time the binding wire pressing column 30 is separated from the binding wire; then the supporting ring seat 41 is continuously rotated, so that the cross-wire opening 20 corresponds to the ring seat opening 70, finally the cross-wire rotating sleeve 10 is pulled towards the cross-wire opening 20, the supporting steel wire A extrudes the V-shaped body 62, the opening and closing channel 63 is opened, and the cross-wire rotating sleeve 10 is separated from the supporting steel wire A.

When the switch is turned on, the driving motor 86 rotates to drive the worm 85 to rotate, so as to drive the two worm gears 84 and the two rotating shafts 83 to rotate, and drive the two transmission gears 82 to rotate. The rotation of the two transmission gears 82 is in the same direction, and the sleeve gear ring 81 drives the cross-wire rotating sleeve 10 to rotate clockwise. The motor driving mode is adopted, and the hand only needs to support the operation handle, and does not need to rotate the hand. The operation mode is simpler.

[0052] The three transmission gears 82 are evenly designed to support the cross-wire rotating sleeve 10 as a whole, and the same worm 85 is used to drive the two worm gears 84 to rotate at the same time. The two transmission gears 82 serve as driving members. When one transmission gear 82 contacts the cross-wire opening, the other transmission gear 82 can still drive the cross-wire rotating sleeve 10 to continue rotating.
