[0012] Referring to FIGS. 1 to 5 together, the fixing clamp (110) for installing multiple vinyl greenhouses according to the present embodiment includes a clamp head member (120), a clamp leg member (130), and a clamp connecting member (115).

[0013] The clamp head member (120) above can be fixed to one of the multiple vinyl films (10) for forming multiple vinyl greenhouses.

[0014] In detail, the clamp head member (120) includes a clamp head curved body (121), a clamp head bottom body (125), a clamp head bottom through hole (126), a clamp head bottom extension body (127), a clamp head stopper (122), a clamp head external force applying body (123), and a clamp head connecting through hole (124).

[0015] The clamp head curved body (121) is formed in a curved shape that contacts the bottom surface of the one fixed to the clamp head member (120) among the multiple vinyl films (10).

[0016] The clamp head curved body (121) is formed in the shape of a tunnel in which a flat plate is bent at a predetermined curvature, so that both sides and the bottom surface are open in the longitudinal direction of the clamp head curved body (121), and both sides are closed in the width direction of the clamp head curved body (121).

[0017] The central part (128) of the clamp head curved body (121) can be formed in a shape that is sunken to a predetermined depth.

[0018] The clamp head bottom body (125) protrudes downward from the center of the bottom surface of the clamp head curved body (121).

[0019] The clamp head bottom body (125) can be formed to be as long as the length of the clamp head curved body (121) in the longitudinal direction of the clamp head curved body (121).

[0020] The above clamp head bottom through hole (126) is formed in a shape that penetrates the clamp head bottom body (125) in the longitudinal direction of the clamp head curved body (121), so that a head catch wire for the clamp head member (120) to be caught penetrates through it.

[0021] The head catch wire is installed lengthwise in the ceiling portion of the multi-plastic greenhouse along the length of the multi-plastic greenhouse. As the head catch wire is formed to sequentially penetrate the bottom penetration holes (126) of each clamp head member (120) constituting each clamp head of the multiple fixing clamps (110) for installing the multi-plastic greenhouse that are arranged along the length of the multi-plastic greenhouse, when the multiple fixing clamps (110) for installing the multi-plastic greenhouse that are arranged along the length of the multi-plastic greenhouse are moved to be spaced apart from each other due to external force from a worker, etc., each clamp head member (120) moves to be spaced apart from each other along the head catch wire, and each part of the multiple vinyl film (10) that is fixed to each clamp head member (120) is spaced apart from each other along the length of the multi-plastic greenhouse, and accordingly, the multiple vinyl film (10) that is fixed to each clamp head member (120) is spread out along the length of the multi-plastic greenhouse. On the other hand, when the multiple fixing clamps (110) for installing the multiple vinyl greenhouses, which are arranged along the length of the multiple vinyl greenhouses, are moved to be close to each other by external force of a worker, the clamp head members (120) are moved along the head catch wire to be close to each other, and the parts of the multiple vinyl films (10) that are fixed to each clamp head member (120) are gripped by each clamp head member (120) are brought close to each other along the length of the multiple vinyl greenhouses, and accordingly, the parts of the multiple vinyl films (10) fixed by each clamp head member (120) are folded along the length of the multiple vinyl greenhouses.

[0022] The clamp head bottom extension (127) is formed in a shape that extends downward from the clamp head bottom body (125).

[0023] The clamp head bottom extension (127) is extended downward by a predetermined length from the bottom of the clamp head bottom body (125), and the lower part of the clamp head bottom extension (127) is formed in a shape that extends further downward than the clamp head external force application body (123).

[0024] The clamp head stopper (122) is formed in a shape that protrudes outward from each bottom end of the clamp head curved body (121).

[0025] The clamp head external force application body (123) extends downward from each end portion of the clamp head curved body (121), and an external force can be applied to cause the clamp head curved body (121) to bend while elastically deforming.

[0026] When a worker holds and tightens a pair of the clamp head external force applying bodies (123) with their hands, the space between each clamp head external force applying body (123) narrows, causing the clamp head curved body (121) to elastically deform and become a shape that can be inserted into the clamp leg member (130). When the external force of the worker is released, the clamp head curved body (121) and each clamp head external force applying body (123) are restored to a circular shape by the self-restoring force of the clamp head curved body (121) and each clamp head external force applying body (123), and the clamp head curved body (121) can be inserted while being in close contact with the clamp leg member (130).

[0027] The clamp head connection through hole (124) is formed in a shape that penetrates the clamp head external force applying body (123) in the width direction of the clamp head external force applying body (123), and a head linkage wire is passed through to allow a plurality of adjacent clamp head members (120) to move together in conjunction.

[0028] The head interlocking wire is installed in a long manner along the ceiling portion of the multi-plastic greenhouse in the width direction of the multi-plastic greenhouse. As the head interlocking wire is formed to sequentially penetrate the clamp head connecting through holes (124) constituting each clamp head member (120) of the multiple fixing clamps (110) for installing the multi-plastic greenhouse arranged in the width direction of the multi-plastic greenhouse, when the multiple fixing clamps (110) for installing the multi-plastic greenhouse arranged in the width direction of the multi-plastic greenhouse are moved to be spaced apart from each other due to external force from a worker, etc., the clamp head members (120) are moved to be spaced apart from each other along the head interlocking wire, and each part of the multiple vinyl film (10) that is fixed to each clamp head member (120) is spaced apart from each other in the width direction of the multi-plastic greenhouse, and accordingly, the multiple vinyl film (10) that is fixed to each clamp head member (120) is spread out in the width direction of the multi-plastic greenhouse. On the other hand, when the multiple fixing clamps (110) for installing the multiple vinyl greenhouses, which are arranged in the width direction of the multiple vinyl greenhouses, are moved to be close to each other by external force of a worker, the clamp head members (120) are moved along the head linkage wire to be close to each other, and the parts of the multiple vinyl films (10) that are fixed to each clamp head member (120) are gripped by each clamp head member (120) are brought close to each other in the width direction of the multiple vinyl greenhouses, and accordingly, the parts of the multiple vinyl films (10) fixed by each clamp head member (120) are folded in the width direction of the multiple vinyl greenhouses.

[0029] The clamp leg member (130) can be fixed to another of the multiple vinyl films (10).

[0030] In detail, the clamp leg member (130) includes a clamp leg curved body (131) and a clamp leg stopper (132).

[0031] The above clamp leg curved body (131) is formed in a curved shape that contacts the upper surface of the one fixed to the clamp leg member (130) among the multiple vinyl films (10).

[0032] The above clamp leg curved body (131) is formed in the shape of a tunnel in which a flat plate is bent at a predetermined curvature, so that both sides and the bottom surface are open in the longitudinal direction of the clamp leg curved body (131), and both sides are closed in the width direction of the clamp leg curved body (131).

[0033] A plurality of leg protrusions (134) are formed on the bottom surface of the clamp leg curved body (131), and the clamp head curved body (121) of the lower of the plurality of fixing clamps (110) for multi-plastic greenhouse installation, which is inserted into the clamp leg curved body (131) (for example, when a plurality of fixing clamps (110) for multi-plastic greenhouse installation are connected to each other vertically), comes into contact with each of the leg protrusions (134), thereby ensuring a stable connection between the clamp leg curved body (131) and the clamp leg curved body (131).

[0034] Reinforcing ribs (133) for reinforcement may be formed along the outer surface of the above clamp leg curved body (131).

[0035] The clamp leg stopper (132) is formed in a shape that protrudes inward from each end of the clamp leg curved body (131).

[0036] As illustrated in FIG. 1, when a plurality of fixing clamps (110) for installing multiple greenhouses are connected to each other vertically, the clamp head curved body (121) of the clamp head member (120) of the lower of the plurality of fixing clamps (110) for installing multiple greenhouses is inserted into the clamp leg curved body (131) of the clamp leg member (130) of the upper of the plurality of fixing clamps (110) for installing multiple greenhouses, and in this state, the clamp head stopper (122) is caught on the clamp leg stopper (132), thereby preventing the arbitrary detachment of the clamp leg member (130) of the upper of the plurality of fixing clamps (110) for installing multiple greenhouses and the clamp head member (120) of the lower of the plurality of fixing clamps (110).

[0037] As described above, as a plurality of the fixing clamps (110) for installing multiple vinyl greenhouses are fastened together vertically, one of the multiple vinyl films (10) for forming the multiple vinyl greenhouses is caught between the clamp leg member (130) of the upper of the plurality of fixing clamps (110) for installing multiple vinyl greenhouses and the clamp head member (120) of the lower of the plurality of fixing clamps (110) for installing multiple vinyl greenhouses, and a larger number of the fixing clamps (110) for installing multiple vinyl greenhouses are fastened vertically (at this time, one of the multiple vinyl films (10) is caught between each clamp head member (120) and each clamp leg member (130) of the upper and lower adjacent fixing clamps (110) for installing multiple vinyl greenhouses), or a lower finishing described later is applied to the clamp leg member (130) of the lowest of the plurality of fixing clamps (110) for installing multiple vinyl greenhouses. By inserting the member (150) (whereby one of the multiple vinyl films (10) is caught between the clamp leg member (130) and the lower finishing member (150) of the multiple fixing clamps (110) for installing multiple vinyl greenhouses), the multiple vinyl films (10) can be installed in multiple parallel while being spaced apart from each other.

[0038] The clamp connecting member (115) is configured such that the clamp head member (120) and the clamp leg member (130) are connected at a predetermined distance apart, so that the multiple vinyl films (10), each fixed by the clamp head member (120) and the clamp leg member (130), are spaced apart from each other.

[0039] The upper part of the clamp connecting member (115) is connected to the lower part of the clamp head bottom extension (127), and the lower part of the clamp connecting member (115) is connected to the upper part of the clamp leg curved body (131).

[0040] Meanwhile, the fixing clamp (110) for installing multiple vinyl greenhouses may further include the lower finishing member (150).

[0041] The lower finishing member (150) is connected to the clamp leg member (130) and supports the one among the multiple vinyl films (10) that is fixed to the clamp leg member (130).

[0042] In detail, the lower finishing member (150) includes a lower finishing curved body (151), a lower finishing stopper (152), a lower finishing bottom body (155), a lower finishing bottom through hole (156), a lower finishing external force applying body (153), and a lower finishing connecting through hole (154).

[0043] The lower end surface (151) is formed in a curved shape so as to be inserted into the clamp leg surface (131) and contacts the bottom surface of the one among the multiple vinyl films (10) that is fixed to the clamp leg member (130).

[0044] The lower finishing curved body (151) is formed in the shape of a tunnel in which a flat plate is bent at a predetermined curvature, so that both sides and the bottom surface are open in the longitudinal direction of the lower finishing curved body (151), and both sides are closed in the width direction of the lower finishing curved body (151).

[0045] The central part (158) of the lower finishing curved body (151) can be formed in a shape that is sunken to a predetermined depth.

[0046] The lower end stopper (152) is formed in a shape that protrudes outward from each end of the lower end curved body (151) so that it can be caught on the clamp leg stopper (132) while the lower end curved body (151) is inserted into the clamp leg curved body (131).

[0047] The lower finishing bottom body (155) protrudes downward from the center of the bottom surface of the lower finishing curved body (151).

[0048] The lower finishing bottom body (155) can be formed to be as long as the length of the lower finishing curved body (151) in the longitudinal direction of the lower finishing curved body (151).

[0049] The lower finishing bottom through hole (156) is formed in a shape that penetrates the lower finishing bottom body (155) in the longitudinal direction of the lower finishing curved body (151), so that a lower finishing catch wire for the lower finishing member (150) to be caught penetrates through it.

[0050] The lower finishing catch wire is installed lengthwise along the ceiling portion of the multi-plastic greenhouse in the longitudinal direction of the multi-plastic greenhouse, but is installed at a relatively lower height compared to the head catch wire. As the lower finishing catch wire is formed to sequentially penetrate the lower finishing bottom penetration holes (156) constituting each lower finishing member (150) of the multiple fixing clamps (110) for installing the multi-plastic greenhouse arranged in the longitudinal direction of the multi-plastic greenhouse, when the multiple fixing clamps (110) for installing the multi-plastic greenhouse arranged in the longitudinal direction of the multi-plastic greenhouse are moved to be spaced apart from each other due to external force from a worker, etc., the lower finishing members (150) are moved to be spaced apart from each other along the lower finishing catch wire, and each part held by the lower finishing member (150) of the multiple vinyl film (10) that is fixed to the lower finishing member (150) is spaced apart from each other in the longitudinal direction of the multi-plastic greenhouse, and accordingly, the lower finishing members of the multiple vinyl film (10) The parts fixed by the member (150) are spread out in the longitudinal direction of the multi-vinyl greenhouse. On the other hand, when the fixing clamps (110) for installing the multi-vinyl greenhouse, which are arranged in the longitudinal direction of the multi-vinyl greenhouse, are moved to be close to each other by external force from a worker, etc., the lower finishing members (150) are moved along the lower finishing catch wire to be close to each other, and the parts of the multiple vinyl films (10) that are fixed to each lower finishing member (150) are held by each lower finishing member (150) are brought close to each other in the longitudinal direction of the multi-vinyl greenhouse, and accordingly, the parts of the multiple vinyl films (10) fixed by each lower finishing member (150) are folded in the longitudinal direction of the multi-vinyl greenhouse.

[0051] The lower finishing external force application body (153) extends downward from each end portion of the lower finishing curved body (151), and an external force can be applied to cause the lower finishing curved body (151) to bend while elastically deforming.

[0052] When a worker holds and tightens a pair of lower finishing external force applying bodies (153) with their hands, the space between each lower finishing external force applying body (153) narrows, causing the lower finishing curved body (151) to elastically deform and become a shape that can be inserted into the clamp leg member (130). When the worker's external force is released, the lower finishing curved body (151) and each lower finishing external force applying body (153) are restored to a circular shape by the self-restoring force of the lower finishing curved body (151) and each lower finishing external force applying body (153), and the lower finishing curved body (151) can be inserted while being in close contact with the clamp leg member (130).

[0053] The lower end connection through hole (154) is formed in a shape that penetrates the lower end external force applying body (153) in the width direction of the lower end external force applying body (153), and a lower end interlocking wire is passed through to allow a plurality of adjacent lower end members (150) to move together in conjunction.

[0054] The lower end interlocking wire is installed lengthwise in the width direction of the multi-vinyl greenhouse along the ceiling portion of the multi-vinyl greenhouse, but is installed at a relatively lower height compared to the head interlocking wire. As the lower end interlocking wire is formed to sequentially penetrate the lower end connecting through holes (154) constituting each lower end member (150) of the multiple fixing clamps (110) for installing the multi-vinyl greenhouse arranged in the width direction of the multi-vinyl greenhouse, when the multiple fixing clamps (110) for installing the multi-vinyl greenhouse arranged in the width direction of the multi-vinyl greenhouse are moved to be spaced apart from each other due to external force from a worker, etc., the lower end members (150) are moved to be spaced apart from each other along the lower end interlocking wire, and each part held by the lower end member (150) of the multiple vinyl film (10) that is fixed to the lower end member (150) is spaced apart from each other in the width direction of the multi-vinyl greenhouse, and accordingly, by the lower end member (150) of the multiple vinyl film (10) The fixed parts are spread out in the width direction of the multiple vinyl greenhouses. On the other hand, when the multiple fixing clamps (110) for installing the multiple vinyl greenhouses, which are arranged in the width direction of the multiple vinyl greenhouses, are moved to be close to each other by external force from a worker, etc., the lower finishing members (150) are moved along the lower finishing interlocking wire to be close to each other, and the parts of the multiple vinyl films (10) that are fixed to each lower finishing member (150) are held by each lower finishing member (150) are brought close to each other in the width direction of the multiple vinyl greenhouses, and accordingly, the parts of the multiple vinyl films (10) fixed by each lower finishing member (150) are folded in the width direction of the multiple vinyl greenhouses.

[0055] As described above, since the fixing clamp (110) for installing multiple vinyl greenhouses includes the clamp head member (120), the clamp leg member (130), and the clamp connecting member (115), each vinyl film (10) can be easily fixed so that the multiple vinyl films (10) for forming multiple vinyl greenhouses are spaced apart from each other, and expansion to three or more multiple layers can be easily achieved.

[0056] Hereinafter, a fixing clamp for installing multiple vinyl greenhouses according to other embodiments of the present invention will be described with reference to the drawings. In carrying out this description, any descriptions that overlap with those already described in the first embodiment of the present invention will be replaced and omitted here.

[0057] FIG. 6 is a front view of a fixing clamp for installing multiple vinyl greenhouses according to a second embodiment of the present invention.

[0058] Referring to FIG. 6, in this embodiment, the clamp head member (220) further includes a through hole (229) for clamp movement.

[0059] The above clamp movement through hole (229) is formed in a shape that penetrates the clamp head bottom body (225) so as to be parallel to the clamp head bottom through hole (226) in the longitudinal direction of the clamp head curved body (221), and a head movement wire for moving the clamp head member (220) is passed through it.

[0060] The above clamp moving through hole (229) can be formed through the lower part of the clamp head bottom through hole (226) in the clamp head bottom body (225).

[0061] The head moving wire is installed along the length of the multi-vinyl greenhouse at the ceiling portion of the multi-vinyl greenhouse, but at a relatively lower height compared to the head catch wire, and is formed in such a way that the head moving wire sequentially penetrates the clamp moving through holes (229) constituting each clamp head member (220) of the plurality of fixing clamps for installing the multi-vinyl greenhouse arranged along the length of the multi-vinyl greenhouse.

[0062] The head moving wire is hung in a closed loop form on a roller installed on the frame of the multi-vinyl greenhouse, and as the roller is rotated by a driving means such as a motor, the head moving wire can be moved while being wound by the roller, and accordingly, each clamp head member (220) through which the head moving wire passes moves together, so that the film fixed to each clamp head member (220) among the multi-vinyl films can be automatically unfolded or folded.

[0063] Hereinafter, a fixing clamp for installing multiple vinyl greenhouses according to a third embodiment of the present invention will be described with reference to the drawings. In carrying out this description, any descriptions that overlap with those already described in the embodiments of the present invention described above will be omitted here.

Accordingly, the first protruding pressure piston (370) and the second protruding pressure piston (375) rise along the first air receiving hole (365) and the second air receiving hole (366) and protrude to the outside of the first air receiving hole (365) and the second air receiving hole (366), and the respective head portions of the first protruding pressure piston (370) and the second protruding pressure piston (375) press the head moving wire inserted into the clamp moving through hole (329), thereby causing the head moving wire inserted into the clamp moving through hole (329) to press the air supply The head moving wire inserted into the clamp moving through hole (329) is prevented from accidentally detaching by being pressed at three points by the piston (362), the first protruding pressure piston (370), and the second protruding pressure piston (375).

[0070] Meanwhile, when the first protruding pressure piston (370) and the second protruding pressure piston (375) rise along the first air receiving hole (365) and the second air receiving hole (366) and protrude outside the first air receiving hole (365) and the second air receiving hole (366), and the respective head portions of the first protruding pressure piston (370) and the second protruding pressure piston (375) press the head moving wire inserted into the clamp moving through hole (329), the first protruding pressure air receiving hole (372) and the second protruding pressure air receiving hole (377) are pressed and deformed, causing the first protruding pressure inflator (373) and the second protruding pressure inflator (378) to expand toward the respective bottom portions of the first air receiving hole (365) and the second air receiving hole (366). As the air inside the first air receiving hole (365) and the second air receiving hole (366) is ejected by the amount of protrusion of the first protruding pressure expansion body (373) and the second protruding pressure expansion body (378), the air is ejected from the first air receiving hole (365) and the second air receiving hole (366) and flows back through the first air flow pipe (363) and the second air flow pipe (364) to the air supply hole (361), and the air supply piston (362) rises by the amount of air that has flowed back into the air supply hole (361), thereby further pressurizing the head moving wire inserted into the clamp moving through hole (329).
