[0022] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a lock structure for greenhouses, comprising: a swing block 1, a first fixing component 5 is arranged on the front surface of the swing block 1, and a second fixing component 6 is arranged on the rear surface of the swing block 1; a first fixing component 5, the first fixing component 5 comprises a fixing seat 501, a rotating shaft 502 is fixedly connected to the rear surface of the fixing seat 501, an outer surface of the rotating shaft 502 is rotatably connected to the inner surface of the swing block 1, a threaded rod 503 is fixedly connected to the front surface of the fixing seat 501, a movable seat 504 is matched to the outer surface of the threaded rod 503, a fixing nut 505 is threadedly rotatably connected to the outer surface of the threaded rod 503 near the front end surface, and the second fixing component 6 comprises a first clamping block 601, and a first clamping block 601 is fixed on one side of the outer surface A limiting block 607 is fixedly connected, the front and rear outer surfaces of the first clamping block 601 are respectively fixedly connected with the first fixing block 603, the outer surface of the other side of the first clamping block 601 is matched with a second clamping block 602, the front and rear outer surfaces of the second clamping block 602 are respectively fixedly connected with the second fixing block 604, the inner surfaces of the two second fixing blocks 604 are respectively rotatably connected with fixing bolts 605, the front surface of the swing block 1 is fixedly connected with the first fixing plate 3 near the top position, the rear surface of the swing block 1 is fixedly connected with the second fixing plate 4 near the top position, the rear surface of the swing block 1 is fixedly connected with the fixing rod 2 near the bottom position, and a limiting groove 608 is provided at the top of the limiting block 607, and the limiting groove 608 is matched with the fixing rod 2.

[0023] The effect achieved by the entire embodiment 1 is that when the lock structure is installed in the greenhouse, the steel pipe in the door frame of the greenhouse is first drilled to make the hole diameter slightly larger than the hole diameter of the threaded rod 503, and the fixed seat 501 is fitted to the surface of the steel pipe of the door frame of the greenhouse. The fixed seat 501 is located on the inner side of the greenhouse, and the threaded rod 503 penetrates the door frame steel pipe from the inside of the greenhouse to the outside. Then, the movable seat 504 is movably sleeved on the outer surface of the threaded rod 503, and the relative arc surfaces of the fixed seat 501 and the movable seat 504 are respectively fitted to the surface of the door frame steel pipe. The fixing nut 501 is tightened by using a tool or manually. 05 is installed on the outer surface of the threaded rod 503, so that under the action of the threaded connection, the fixed seat 501 and the movable seat 504 are tightly fixed on the surface of the door frame steel pipe, and then the first clamping block 601 and the second clamping block 602 are respectively attached to the surface of the steel pipe on one side of the greenhouse sliding door. The installation position corresponds to the position of the swing block 1, and the two fixing bolts 605 are respectively inserted into the two second fixing blocks 604 and the first fixing block 603 in turn. Use tools or hand-tightening to screw the two fixing bolts 605 clockwise. The first fixing block 603 is threadedly connected, and plays a fixing role, so that the two clamping blocks are tightly fixed on the surface of the steel pipe on one side of the sliding door. When the sliding door is pushed, the sliding door drives the limit block 607 to move in the direction of the swing block 1. At this time, the personnel on the inside can lift the first fixing plate 3, and when the personnel are outside the shed, they press the second fixing plate 4, so that the swing block 1 will rotate with the outer surface of the rotating shaft 502 as the axis, and the swing block 1 drives the fixing rod 2 to tilt upward. When the sliding door drives the limit block 607 to move to the fixing rod 2, the control of the swing block 1 is released, so that it is under the weight. Under the action of force, the fixing rod 2 falls into the limiting groove 608, which plays a locking role. By setting the lock structure to a split structure, the locking lock and the movable buckle are respectively fixed on the surface of the first fixing component 5 and the second fixing component 6, so that it can be quickly installed between the greenhouse door frame and the sliding shed door. When replacing, only the fixing nut 505 and the fixing bolt 605 need to be turned in turn to quickly separate the lock structure from the greenhouse door frame and the movable shed door, which plays a role of quick disassembly and assembly, facilitates personnel to quickly replace, and improves the use effect of the lock structure for the greenhouse.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, the outer surface of the fixing bolt 605 is threadedly connected to the inner surfaces of the two first fixing blocks 603, and the outer surface of the fixing bolt 605 is symmetrically fixedly connected to the second connecting block 606 at a position away from the first fixing block 603. The movable seat 504 is located between the fixing nut 505 and the fixed seat 501. The relative outer surfaces of the movable seat 504 and the fixed seat 501 are both arc-shaped. The fixing nut 505 and the movable seat 504 are matched with each other, and the outer surface of the fixing nut 505 is symmetrically fixedly connected to the first connecting block 506.

[0025] The effect achieved by the entire embodiment 2 is that, when fixing, by symmetrically fixing the first connecting block 506 on the outer surface of the fixing nut 505, and symmetrically fixing the second connecting block 606 on the outer surface of the fixing bolt 605, personnel can manually tighten the fixing nut 505 or the fixing bolt 605, which is convenient for quickly installing and fixing the locking structure when personnel lack tools, thereby improving the use effect of the locking structure for greenhouses.

[0026] Working principle: When installing the lock structure in the greenhouse, first drill a hole in the steel pipe in the door frame of the greenhouse so that its diameter is slightly larger than the diameter of the threaded rod 503, and fit the fixed seat 501 to the surface of the steel pipe of the door frame of the greenhouse. The fixed seat 501 is located on the inside of the greenhouse, and the threaded rod 503 penetrates the door frame steel pipe from the inside of the greenhouse to the outside. Then, the movable seat 504 is movably sleeved on the outer surface of the threaded rod 503. The relative arc surfaces of the fixed seat 501 and the movable seat 504 are respectively fitted to the surface of the door frame steel pipe. Use tools or manually twist to tighten the fixing nut 501. 5 is installed on the outer surface of the threaded rod 503, so that under the action of the threaded connection, the fixed seat 501 and the movable seat 504 are tightly fixed on the surface of the door frame steel pipe, and then the first clamping block 601 and the second clamping block 602 are respectively attached to the surface of the steel pipe on one side of the greenhouse sliding door, and the installation position corresponds to the position of the swing block 1, and the two fixing bolts 605 are respectively inserted into the two second fixing blocks 604 and the first fixing block 603 in turn, and the two fixing bolts 605 are respectively screwed clockwise using tools or hand screwing. The surface of the bolt 605 is threadedly connected with the first fixing block 603, which plays a fixing role, so that the two clamping blocks are tightly fixed on the surface of the steel pipe on one side of the sliding door. When the sliding door is pushed, the sliding door drives the limit block 607 to move in the direction of the swing block 1. At this time, when the personnel are on the inside, they can lift the first fixing plate 3, and when the personnel are outside the shed, they press the second fixing plate 4, so that the swing block 1 will rotate with the outer surface of the rotating shaft 502 as the axis, and the swing block 1 drives the fixing rod 2 to tilt upward. When the sliding door drives the limit block 607 to move to the fixing rod 2 When the locking nut 505 is in the working state, the fixing rod 2 is symmetrically fixed on the outer surface of the fixing nut 505, and the second connecting block 606 is symmetrically fixed on the outer surface of the fixing bolt 605, so that the fixing nut 505 or the fixing bolt 605 can be manually tightened, which is convenient for quickly installing and fixing the locking structure when the personnel lack tools, thereby improving the use effect of the locking structure for greenhouses.
