Description

Technical Field

[0001] This utility model belongs to the field of frame splicing technology, and in particular relates to a splicing device for explosion-proof window frames. Background Technology

[0002] In the production and processing of explosion-proof windows, frame splicing is a key process to ensure the overall structural strength and explosion-proof performance. The splicing accuracy and connection stability directly affect the safety of the explosion-proof window.

[0003] Existing explosion-proof window frame splicing devices still have many shortcomings in practical applications: explosion-proof window frames are mostly corner splicing structures. During the splicing process, it is necessary to simultaneously achieve the lateral positioning of the frame and the longitudinal limiting of the connection. However, the positioning mechanism and limiting mechanism of the existing device often lack coordinated adaptation settings, which leads to problems such as lateral displacement and longitudinal loosening of the frame. This not only causes splicing angle deviation and uneven gaps, affecting the splicing accuracy, but also weakens the structural stability of the frame after splicing, thus adversely affecting the overall explosion-proof performance and safety of the explosion-proof window.

[0004] There is an urgent need for improvement, so we propose an explosion-proof window frame splicing device. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing an explosion-proof window frame splicing device. This device achieves a vertical positioning space formed by the baffles on both sides of the base plate and the extrusion block. The extrusion block is driven by the pushing mechanism to move along the sliding assembly and cooperate with the baffles to achieve lateral extrusion positioning of the frame. At the same time, the pressure roller of the pressing mechanism applies longitudinal limiting to the connection of adjacent frames, so as to achieve the effect of lateral positioning and longitudinal limiting working together to avoid lateral displacement or longitudinal loosening of the frame.

[0006] In view of this, the present invention provides an explosion-proof window frame splicing device, a base plate, on both sides of the surface of the base plate being symmetrically and vertically fixed with baffles, and a pressing block being slidably connected to the surface of the base plate between the two baffles through a sliding assembly, the two ends of the pressing block being vertically arranged and parallel to the two baffles respectively;

[0007] A pushing mechanism is installed at one end of the extrusion block and cooperates with a sliding component to drive the extrusion block to move.

[0008] The pressing mechanism includes a pressure plate rotatably connected to the top of the extrusion block via a rotation limiting component. The bottom end of the pressure plate is connected to a frame via an adjustment component. A pressure roller for limiting the connection between two adjacent frames is fixed on the inner side of the frame.

[0009] Furthermore, the pushing mechanism includes a fixed plate fixedly connected to the middle of the base plate surface between the two baffles, a screw threaded through the fixed plate, and the end of the screw near the extrusion block is rotatably connected to the extrusion block.

[0010] Furthermore, the sliding assembly includes a groove formed in the middle of the base plate surface and a slider slidably connected in the groove, the surface of the slider being fixedly connected to the bottom end of the extrusion block.

[0011] Furthermore, the rotation limiting assembly includes connecting plates symmetrically fixedly connected to both sides of the surface of the extrusion block, and both ends of the pressure plate are fixedly connected to rotating shafts, with the other ends of the two rotating shafts respectively rotatably connected to the inner sides of the two connecting plates;

[0012] One of the rotating shafts is fixedly connected to a limiting plate on its outer periphery. The limiting plate has several slots equidistantly spaced on its outer periphery. A mounting plate is fixedly connected to a connecting plate near the limiting plate. A T-shaped push rod slides through the mounting plate. A locking block is fixedly connected to the bottom end of the push rod, and the locking block is adapted to the slot. A spring is sleeved on the outside of the push rod above the mounting plate.

[0013] Furthermore, the adjustment assembly includes an adjustment groove formed at the bottom end of the pressure plate and an adjustment block slidably connected in the adjustment groove. A lead screw is rotatably connected between the two ends of the inner cavity of the adjustment groove. The adjustment block is threaded onto the outer circumference of the lead screw. The frame is fixedly connected to the bottom end of the adjustment block.

[0014] Furthermore, one end of the lead screw rotates through the adjustment groove and is positioned on the outside of the pressure plate, and a handle is fixedly connected to the lead screw on the outside of the pressure plate.

[0015] Furthermore, a torsion spring is fitted around the outer periphery of the two rotating shafts that is furthest from the limiting disc.

[0016] Furthermore, the two mutually perpendicular ends of the extrusion block are provided with grooves, and the inner cavities of the two grooves are rotatably connected to guide rollers, with each guide roller having at most one-third of its length placed on the outside of the groove.

[0017] Furthermore, a handwheel is fixedly connected to the end of the screw away from the extrusion block, and an anti-slip groove is provided on the outer side of the handwheel.

[0018] The beneficial effects of this utility model are:

[0019] The vertical positioning space is formed by the baffles on both sides of the base plate and the extrusion block. When the pushing mechanism drives the extrusion block to move along the sliding assembly, it can cooperate with the baffles on both sides to form a lateral extrusion positioning of the frame. At the same time, the pressure roller of the pressing mechanism can apply longitudinal limit to the connection of adjacent frames, so as to achieve the coordinated adaptation of lateral positioning and longitudinal limit, and avoid lateral displacement or longitudinal loosening of the frame.

[0032] Reference Figures 1 to 5 An explosion-proof window frame splicing device includes: a base plate 1, on both sides of the surface of the base plate 1, baffles 2 are symmetrically and vertically fixed, and a pressing block 6 is slidably connected to the surface of the base plate 1 between the two baffles 2 through a sliding assembly. The two ends of the pressing block 6 are vertically arranged and are parallel to the two baffles 2 respectively.

[0033] A pushing mechanism is installed at one end of the extrusion block 6. The pushing mechanism cooperates with the sliding component to drive the extrusion block 6 to move.

[0034] The pressing mechanism includes a pressure plate 11 rotatably connected to the top of the extrusion block 6 via a rotation limiting component. The bottom end of the pressure plate 11 is connected to a frame 12 via an adjustment component. A pressure roller 13 for limiting the connection between two adjacent frames is fixed on the inner side of the frame 12.

[0035] This application forms a vertical positioning space with the baffles 2 on both sides of the base plate 1 and the extrusion block 6. When the pushing mechanism drives the extrusion block 6 to move along the sliding assembly, it can cooperate with the baffles 2 on both sides to form a lateral extrusion positioning of the frame. At the same time, the pressure roller 13 of the pressing mechanism can apply a longitudinal limit to the connection of adjacent frames, so as to achieve the coordinated adaptation of lateral positioning and longitudinal limit, and avoid lateral displacement or longitudinal loosening of the frame.

[0036] In the example of this application, the pushing mechanism includes a fixed plate 5 fixedly connected to the middle of the surface of the base plate 1 between the two baffles 2, a screw 7 threaded through the fixed plate 5, and the end of the screw 7 near the extrusion block 6 is rotatably connected to the extrusion block 6.

[0037] As a preferred example of this utility model, the driving mechanism adopts a screw 7 and a fixed plate 5 with a threaded engagement, and rotating the screw 7 can smoothly drive the extrusion block 6 to move.

[0038] In the example of this application, the sliding component includes a groove 3 formed in the middle of the surface of the base plate 1 and a slider 4 slidably connected in the groove 3, the surface of the slider 4 being fixedly connected to the bottom end of the extrusion block 6.

[0039] As a preferred example of this utility model, the sliding cooperation between the groove 3 and the slider 4 provides a stable moving guide for the extrusion block 6, ensuring that the extrusion block 6 does not deviate during the lateral extrusion process and improving the lateral positioning accuracy.

[0040] In the example of this application, the rotation limiting assembly includes connecting plates 10 symmetrically fixedly connected to both sides of the surface of the extrusion block 6, and both ends of the pressure plate 11 are fixedly connected to rotating shafts 15, and the other ends of the two rotating shafts 15 are respectively rotatably connected to the inner side of the two connecting plates 10.

[0041] One of the rotating shafts 15 is fixedly connected to a limiting disk 16 on its outer periphery. The limiting disk 16 has several slots 20 evenly spaced on its outer periphery. A mounting plate 17 is fixedly connected to a connecting plate 10 near the limiting disk 16. A T-shaped push rod 18 slides through the mounting plate 17. A locking block 21 is fixedly connected to the bottom end of the push rod 18, and the locking block 21 is adapted to the slots 20. A spring 19 is sleeved on the outside of the push rod 18 above the mounting plate 17. The two ends of the spring 19 are fixedly connected to the head of the push rod 18 and the mounting plate 17, respectively.

[0042] As a preferred example of this utility model, the pressure plate 11 is rotatably connected to the connecting plate 10 via the rotating shaft 15, allowing for flexible angle adjustment. The slot 20 on the outer periphery of the limiting disk 16 and the locking block 21 form a locking engagement structure. Under the elastic force of the spring 19, the locking block 21 is always pressed against and locked into the slot 20 of the limiting disk 16. This allows for switching between different angles as the pressure plate 11 rotates. When rotating, the locking block 21 compresses the spring 19, disengages from the current slot 20, and locks into the next slot 20. Furthermore, the mechanical engagement between the slot 20 and the locking block 21 restricts the pressure plate 11 from rotating in the opposite direction, thereby stably fixing the pressure plate 11 at a preset angle. This satisfies the angle requirements of different splicing scenarios and ensures the reliability of the adjusted structure with its unidirectional limiting characteristic, effectively preventing angle loosening.

[0043] In the example of this application, the adjustment assembly includes an adjustment groove 25 formed at the bottom end of the pressure plate 11 and an adjustment block 26 slidably connected in the adjustment groove 25. A lead screw 27 is rotatably connected between the two ends of the inner cavity of the adjustment groove 25. The adjustment block 26 is threaded onto the outer periphery of the lead screw 27. The frame 12 is fixedly connected to the bottom end of the adjustment block 26.

[0044] As a preferred example of this utility model, the adjusting block 26 is driven by the lead screw 27 to slide along the adjusting groove 25, which can drive the pressure roller 13 to move laterally and adjust the corresponding position of the pressure roller 13 at the connection with the frame to adapt to the splicing requirements of different frame specifications.

[0045] In the example of this application, one end of the lead screw 27 rotates through the adjustment groove 25 and is placed on the outside of the pressure plate 11, and a handle 14 is fixedly connected to the lead screw 27 on the outside of the pressure plate 11.

[0046] As a preferred example of this utility model, the handle 14 facilitates manual rotation of the lead screw 27, simplifies the adjustment of the position of the pressure roller 13, and makes it easy to press down the pressure roller 13 by hand, thus improving ease of use.

[0047] In the example of this application, a torsion spring 22 is sleeved on the outer periphery of the two rotating shafts 15 that are away from the limiting disk 16. The inner ring of the torsion spring 22 is adapted to the shaft, and the two free ends of the torsion spring 22 are fixedly connected to the surface of the rotating shaft 15 and the inner side of the connecting plate 10, respectively.

[0048] As a preferred example of this utility model, the torsion spring 22 undergoes elastic deformation as the shaft 15 rotates, providing a restoring force for the pressure plate 11, assisting the pressure plate 11 in quickly restoring or maintaining stable pressure after angle adjustment, thereby enhancing the flexibility and stability of angle adjustment.

[0049] In the example of this application, the end faces of the two mutually perpendicular ends of the extrusion block 6 are provided with grooves 23, and the inner cavities of the two grooves 23 are rotatably connected to guide rollers 24, and each guide roller 24 is placed at most one-third outside the groove 23.

[0050] As a preferred example of this utility model, when the guide roller 24 on the end face of the extrusion block 6 contacts the frame, rolling friction replaces hard friction, reducing scratch damage to the frame surface. At the same time, the exposed portion of the guide roller 24 ensures a tight fit with the frame and does not affect the lateral positioning effect. The overall structure, through the synergistic effect of each component, effectively improves the splicing accuracy, structural stability, and ease of operation, ensuring the explosion-proof performance and safety of the explosion-proof window.

[0051] In the example of this application, a handwheel 8 is fixedly connected to the end of the screw 7 away from the extrusion block 6, and an anti-slip groove 9 is provided on the outer side of the handwheel 8.

[0052] As a preferred example of this utility model, the handwheel 8 is easy for personnel to hold, and the anti-slip groove 9 increases the friction of the handwheel 8, further facilitating the stable rotation of the screw 7 by the personnel.

[0053] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
