DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 4As shown, an adjustable concrete precast component mold described in an embodiment of the utility model comprises a mold shell 1; an adjusting plate 12 is slidably connected to the middle part of the mold shell 1; screws 13 are fixedly connected to both sides of the mold shell 1; the middle part of the adjusting plate 12 is slidably matched with the screw 13; a pair of nuts 14 are threadedly connected to the middle part of the screw 13; the adjusting plate 12 is located between the pair of nuts 14; a plurality of slots 15 are provided in the middle part of the nut 14; a connecting piece 16 is rotatably connected to the middle part of the pair of nuts 14; a slide plate 17 is slidably connected to the inside of the slot 15; a card plate 18 is fixedly connected to the bottom of the slide plate 17; a first spring 19 is fixedly connected to the top of the slide plate 17; the other end of the first spring 19 is fixedly connected to the inner middle part of the connecting piece 16; a first pull rope 110 is fixedly connected to the top of the pair of slide plates 17; when working, when it is necessary to change the width of the mold according to the size requirements of the concrete precast component, the connecting piece 16 rotates in the corresponding direction. At this time, the card plate 18 trapped in the card slot 15 will drive the pair of nuts 14 to rotate, and then the pair of nuts 14 will move synchronously along the middle part of the screw rod 13. By rotating the pair of connecting members 16, the adjusting plate 12 is driven to move. After the connecting member 16 completes a rotation, the first pull rope 110 is pulled to make the slide plate 17 drive the card plate 18 to rise, so that the card plate 18 is no longer matched with the nut 14, and then the connecting member 16 is rotated, and the first pull rope 110 is released again, so that the card plate 18 extends into the inside of the card slot 15 under the elastic force of the first spring 19, so that the nut 14 can continue to rotate. By repeating the above operation, the position of the adjusting plate 12 can be adjusted, and the width of the mold groove can be expanded or reduced. Through the above structure, the effective width of the concrete precast component mold can be adjusted, so as to facilitate the production of concrete precast components with different width requirements.

[0024] like Figures 1 to 5As shown, the middle parts of a pair of connecting members 16 are rotatably connected with a rotating ring 2; a gripping rod 21 is fixedly connected to the middle parts of a pair of rotating rings 2; a pair of fixed shafts 22 are fixedly connected to the bottom of the gripping rod 21; a pair of second springs 23 are fixedly connected to the bottom of the gripping rod 21; a connecting plate 24 is fixedly connected to the bottom of a pair of second springs 23; a pair of second pull ropes 25 are fixedly connected to the bottom of the connecting plate 24; the second pull rope 25 is arranged around the middle part of the fixed shaft 22, and the other end of the second pull rope 25 is fixedly connected to the middle part of the first pull rope 110; during operation, when it is necessary to adjust the position of the adjustment plate 12, the gripping rod 21 can be held and moved toward the direction of one connecting member 16, thereby driving the pair of connecting members 16 to rotate at the same time. Thereby, both ends of the adjustment plate 12 can slide in the middle of a pair of screw rods 13 at the same time. By holding the connecting plate 24 and making the connecting plate 24 fit toward the direction of the grip rod 21, the second pull rope 25 can be driven to pull the first pull rope 110, thereby disengaging the multiple card plates 18 from the corresponding card slots 15. After loosening the connecting plate 24, the connecting plate 24 will move away from the grip rod 21 under the elastic force of the second spring 23, thereby allowing the multiple card plates 18 to enter the corresponding card slots 15. Through the above structure, multiple nuts 14 can be rotated and adjusted at the same time, which improves the convenience of operation and saves operation time. Adjusting multiple nuts 14 at the same time can also make the two ends of the adjustment plate 12 move synchronously, reducing the occurrence of the adjustment plate 12 getting stuck.

[0025] like Figures 1 to 5 As shown, a pair of limit rods 3 are fixedly connected to the bottom of the gripping rod 21; the middle part of the connecting plate 24 is slidingly matched with the limit rod 3; the bottom end of the limit rod 3 is fixedly connected to the limit head 31; during operation, when the connecting plate 24 approaches or moves away from the gripping rod 21, the connecting plate 24 will slide along the middle part of the limit rod 3, thereby reducing the displacement of the connecting plate 24; when the connecting plate 24 moves away from the gripping rod 21 under the elastic force of the second spring 23, the limit head 31 will hinder the gripping rod 21, thereby reducing the movement distance of the connecting plate 24 that is too long, resulting in the second pull rope 25 being detached from the middle part of the fixed shaft 22. Through the above structure, the movement path of the connecting plate 24 can be standardized, thereby reducing the occurrence of errors in the matching of the components.

[0026] like Figures 1 to 4 As shown, the internal rotation of the connecting member 16 is connected with multiple circular shafts 4; the multiple circular shafts 4 are arranged at the bending part of the first pull rope 110; when working, when the slide plate 17 is moved by pulling the first pull rope 110, the middle part of the first pull rope 110 will generate sliding friction with the internal corner of the connecting member 16. The setting of multiple circular shafts 4 can convert the sliding friction between the first pull rope 110 and the connecting member 16 into rolling friction, thereby reducing the damage to the first pull rope 110 caused by friction.

[0027] like Figures 1 to 5 As shown, a pair of elastic membranes 5 are fixedly connected to the bottom of the connecting member 16; the other ends of the pair of elastic membranes 5 are fixedly connected to the side walls of the connecting plate 24; during operation, when the gripping rod 21 and the connecting plate 24 are held to reduce the distance between the two, the elastic membranes 5 will block the operator's palm, which can reduce the situation where the flesh in the middle of the operator's palm is clamped by the gripping rod 21 and the connecting plate 24 to a certain extent.

[0028] like Figures 1 to 5 As shown, a plurality of anti-skid protrusions 6 are provided in the middle of the gripping rod 21; the anti-skid protrusions 6 are densely arranged in the middle of the gripping rod 21; during operation, when demoulding is required, the side wall of the adjustment plate 12 will be tightly combined with the solidified precast concrete component, so a greater force is required to rotate a pair of nuts 14, and then a greater force is required to drive the gripping rod 21 to move. The provision of a plurality of anti-skid protrusions 6 can increase the friction between the operator's hand and the gripping rod 21, thereby reducing the occurrence of hand slippage and facilitating the operator to exert force.

[0029] like Figure 5 As shown, the bottom of the connecting plate 24 is fixedly connected with flexible cotton 7; the flexible cotton 7 is a flexible liquid-absorbing material; during operation, when the operator holds the handle 21 and the connecting plate 24, the flexible cotton 7 will absorb the sweat of the operator's hands, further reducing the occurrence of the operator's hand slipping.

[0030] During operation, when the width of the mold needs to be changed according to the size requirements of the concrete precast part, the connecting member 16 is rotated in the corresponding direction. At this time, the card plate 18 trapped in the card slot 15 will drive the pair of nuts 14 to rotate, and then the pair of nuts 14 will move synchronously along the middle of the screw rod 13. By rotating the pair of connecting members 16, the adjustment plate 12 is driven to move. After the connecting member 16 completes a rotation, the first pull rope 110 is pulled to make the slide plate 17 drive the card plate 18 to rise, so that the card plate 18 is no longer matched with the nut 14, and then the connecting member 16 is rotated, and the first pull rope 110 is released, so that the card plate 18 extends into the slot under the elastic force of the first spring 19. The inside of the card slot 15 can continue to drive the nut 14 to rotate. By repeatedly performing the above operation, the position of the adjustment plate 12 can be adjusted to expand or reduce the width of the mold slot. When the position of the adjustment plate 12 needs to be adjusted, the gripping rod 21 can be held and moved toward a connecting piece 16, thereby driving a pair of connecting pieces 16 to rotate at the same time, so that the two ends of the adjustment plate 12 can slide in the middle of a pair of screw rods 13 at the same time. By holding the connecting plate 24 and making the connecting plate 24 fit toward the direction of the gripping rod 21, the second pull rope 25 can be driven to pull the first pull rope 110, so that multiple card plates 18 are moved from the corresponding card plates 18 to the corresponding card plates 18. When the connecting plate 24 moves away from the gripping rod 21, the connecting plate 24 will slide along the middle part of the limiting rod 3 to reduce the displacement of the connecting plate 24. When the connecting plate 24 moves away from the gripping rod 21 under the elastic force of the second spring 23, the limiting head 31 will hinder the gripping rod 21 to reduce the movement distance of the connecting plate 24, which will cause the second pull rope 25 to be detached from the middle part of the fixed shaft 22. When moving, the middle part of the first pull rope 110 will generate sliding friction with the inner corner of the connecting piece 16. The setting of multiple circular shafts 4 can convert the sliding friction between the first pull rope 110 and the connecting piece 16 into rolling friction. When the gripping rod 21 and the connecting plate 24 are held to reduce the distance between the two, the elastic membrane 5 will block the operator's palm. When demolding is required, the side wall of the adjustment plate 12 will be tightly combined with the solidified precast concrete component. Therefore, a greater force is required to turn a pair of nuts 14, and then a greater force is required to drive the gripping rod 21 to move. The setting of multiple anti-slip protrusions 6 can increase the friction between the operator's hand and the gripping rod 21.
