Description

Technical Field

[0001] This utility model relates to the field of elevators, specifically to a door operator device. Background Technology

[0002] The existing door operator device includes a main body, a door hanging plate that can reciprocate horizontally on the main body and has a door body, and a drive component that drives the door hanging plate to move. There are two door hanging plates that are linked together by a linkage component. The drive component drives one of the door hanging plates to move, so that the door hanging plate drives the other door hanging plate to mirror linkage through the linkage component. This allows the door plates to switch between a closed state where they are tightly fitted together by corresponding side edges and an open state where they are separated from each other.

[0003] The drive assembly includes a transmission belt driven by a motor and a boom vertically spanning between the door panel and the transmission belt. During assembly, the upper part of the boom is fixed to the transmission belt, and the lower part is fixed to the door panel. The boom body is suspended below the door panel, so that the boom, door panel, and door body are fixedly connected from top to bottom. In use, when the door panel switches to the closed state, the corresponding side edges of the door panel will fit together. Due to the large height difference between the connection point of the boom and the transmission belt and the top edge of the corresponding side wall of the door panel, a large lever arm is formed. When the upper part of the boom shifts due to excessive displacement of the transmission belt, the horizontal force generated by the shift will be amplified by the lever arm, using the top edge of the door panel side wall as a fulcrum to drive the bottom edge of the door panel side wall to separate in opposite directions. This causes the door panel side wall to tilt, and the separation of the bottom edges of the door panel side walls forms a large gap. This not only poses a significant safety hazard to the door operator, causing the door panel to become unable to lock due to the tilt of the door body, but also makes the door body prone to deformation due to localized concentrated force, affecting its service life. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a door operator device with good limiting effect. By setting an upper limiting part and a lower limiting part, the posture of the boom is positioned to ensure that the door body can be matched and fitted in a vertical posture. This not only effectively eliminates safety hazards but also prevents door body deformation, extends service life, and improves user experience.

[0005] This utility model is achieved through the following means: a door operator device with good limiting effect, including a main body, two door hanging plates that can reciprocate horizontally on the main body and have door bodies, and a drive assembly for driving the door hanging plates to move. The drive assembly includes a transmission belt driven by a motor and a boom vertically spanning between the door hanging plates and the transmission belt. The door body is fixed to the bottom of the door hanging plates. The door body is driven by the boom to switch between a mutually separated open state and a mutually tightly fitted closed state. The main body is provided with a vertically separated upper limiting part and a lower limiting part. When the door body is switched to the closed state, the boom can synchronously abut against the upper limiting part and the lower limiting part to maintain the vertical posture, so that the door body is matched and positioned in the closed state in a vertical posture. The upper and lower limiting parts are installed to position and maintain the boom's vertical posture, ensuring the door body fits snugly in a vertical position. This effectively eliminates safety hazards, ensures a tight fit against the corresponding side walls of the door, eliminates gaps, and prevents deformation due to concentrated localized stress. It also ensures smooth opening and closing, extends the door's lifespan, and improves the user experience. The upper and lower limiting parts can directly or indirectly limit the boom's position. Utilizing the principle of two points determining a line, the upper and lower limiting parts, with their different heights, limit corresponding sections of the boom, maintaining its vertical posture and thus correcting and positioning the door body.

[0006] Preferably, when the door is switched to the closed state, the door is vertical, and corresponding sections on the corresponding side edges of the door are fitted together. The boom is fixed to the door via the door mounting plate, and the relative positions and postures of the three are fixed. The boom is used to adjust and correct the posture of the door, ensuring that the door can fit tightly against the side walls when switched to the closed state. Specifically, corresponding sections at the same height on the corresponding side walls of the door can fit tightly together to prevent gaps from forming due to the non-parallelism of the corresponding side walls.

[0007] Preferably, both the upper and lower limiting parts are located below the connection between the transmission belt and the boom. The upper limiting part is located at the top of the main body and close to the transmission belt, thus limiting excessive movement of the boom tip by reducing the height difference between the upper limiting part and the transmission belt. The proximity of the upper limiting part to the connection between the transmission belt and the boom effectively reduces the distance between them, thereby reducing the force exerted on the boom by excessive transmission belt movement. Simultaneously, it effectively increases the distance between the gate and the upper limiting part, increasing the resistance to boom posture changes by increasing the lever arm. This combination of increased resistance and reduced force ensures the boom remains in a vertical position, thereby ensuring precise opening and closing of the gate.

[0008] Preferably, the connection between the drive belt and the boom is located between the upper and lower limiting parts. Because the connection is located between the upper and lower limiting parts, it provides rigid positioning for the displacement of the drive belt, ensuring that the boom remains in a vertical position, thereby ensuring the precise opening and closing of the door.

[0009] Preferably, the main body is provided with a limiting member that can abut against the upper part of the boom, and the limiting member has a horizontally exposed upper limiting part. The limiting member is installed on the main body to form the upper limiting part, which not only facilitates disassembly and maintenance, but also allows for adjustment of the position of the limiting member, thereby ensuring that the boom is in a vertical position when it abuts against the upper limiting part, thus improving positioning accuracy.

[0010] Preferably, the limiting member is mounted on the top of the main body via a connecting plate, so that the upper limiting part of the limiting member is horizontally exposed. The connecting plate is fixed to the main body with fasteners, which facilitates height adjustment of the limiting member, ensuring that the upper limiting part can be set in a preset position, and also facilitates disassembly and maintenance.

[0011] Preferably, the connecting plate is L-shaped, including a fixing part that is fixedly attached to the top edge of the main body and a connecting part that is fixedly attached to the limiting member. The limiting member is telescopically and adjustablely mounted on the connecting part. The fixing part is horizontally positioned and fixed to the main body by fasteners, while the connecting part is vertically positioned. This design facilitates fixing the limiting member at a preset height as needed and ensures that the limiting member is reliably positioned.

[0012] Preferably, the limiting member is elongated, with a mounting hole on the connecting portion. One end of the limiting member is adjustablely inserted through the mounting hole and fixed with bolts, while the other end extends horizontally to form the upper limiting portion. The axis of the limiting member is set along the movement direction of the boom, allowing the limiting member to be movable and adjustable. This ensures that the position of the upper limiting portion can be adjusted as needed and fixed with bolts after adjustment, effectively improving the reliability of the boom's contact positioning.

[0013] Preferably, the boom is provided with an abutment plate perpendicular to its direction of movement. When the door is switched to the closed state, the boom is positioned by abutting against the upper limiting part through the abutment plate. By providing the abutment plate, the area available for the upper limiting part to abut is increased, which not only improves the reliability of the abutment positioning and prevents slippage, but also ensures that the upper limiting part can accurately abut against the abutment plate.

[0014] Preferably, when the door is switched to the closed state, the lower limiting parts of the corresponding booms are mutually constrained. The bottom of the boom is fixed to the door through a door hanging plate and is positioned by abutting against the corresponding lower limiting parts. The lower limiting parts formed by the corresponding side edges of the door abut against each other, which abuts against the corresponding booms to ensure that the booms remain in a vertical position.

[0015] Preferably, the boom is fixed to a straight section of the drive belt by a clamp, with the clamp and drive belt overlapping and fixed together, so that the boom can reciprocate horizontally in a vertical position under the drive of the drive belt. The vertical overlap of the clamp and drive belt not only increases the contact area to improve the reliability of the fixation, but also ensures that the corresponding section of the boom and drive belt remain perpendicular, thereby ensuring that the boom maintains a vertical position.

[0016] The beneficial effects of this utility model are as follows: By setting the upper limiting part and the lower limiting part, the posture of the boom is positioned and maintained in a vertical position, ensuring that the door can be matched and fitted in a vertical position. This not only effectively eliminates safety hazards and ensures that the corresponding side walls of the door fit tightly, effectively eliminating gaps, but also ensures that the door will not deform due to localized concentrated force, ensuring smooth opening and closing of the door, effectively extending its service life and improving the user experience.

[0021] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 and 2The door operator device shown has a good limiting effect. It consists of a main body 1, two door hanging plates 2 that can reciprocate horizontally on the main body 1 and have door bodies 3, and a drive assembly 4 that drives the door hanging plates 2 to move. The drive assembly 4 includes a transmission belt 5 driven by a motor and a hanging arm 6 that is vertically connected between the door hanging plates 2 and the transmission belt 5. The door body 3 is fixed to the bottom of the door hanging plates 2. The door body 3 is driven by the hanging arm 6 to switch between an open state that is separated from each other and a closed state that is tightly fitted together. The main body 1 is provided with a vertically separated upper limiting part 7 and a lower limiting part 8. When the door body 3 is switched to the closed state, the hanging arm 6 can synchronously abut against the upper limiting part 7 and the lower limiting part 8 to maintain the vertical posture, so that the door body 3 is matched and positioned in the closed state in a vertical posture. The upper limiting part 7 and the lower limiting part 8 are set to position the boom 6 and maintain its vertical posture, ensuring that the door 3 can be matched and fitted in a vertical posture. This not only effectively eliminates safety hazards and ensures that the corresponding side wall of the door 3 fits tightly, effectively eliminating gaps, but also ensures that the door 3 will not deform due to localized concentrated force, ensuring smooth opening and closing of the door 3, effectively extending its service life and improving the user experience.

[0023] In actual operation, the upper limiting part 7 and the lower limiting part 8 can directly or indirectly limit the boom 6. Utilizing the principle that two points determine a line, the upper limiting part 7 and the lower limiting part 8, which have different heights, limit corresponding sections of the boom 6, keeping the boom 6 in a vertical position, thereby correcting and positioning the posture of the door 3. A limiting member 10 is installed on the main body 1, forming the upper limiting part 7, which can directly contact the boom 6. When the door body 3 is switched to the closed state, it forms a lower limiting part 8 corresponding to the boom 6. The bottom of the boom 6 is fixed to the door body 3 through the door hanging plate 2 and is positioned by abutting against the corresponding lower limiting part 8. When the door body 3 is switched to the closed state, it can abut against the corresponding side edge, so that the bottom of the boom 6 can indirectly abut against the lower limiting part 8 formed by the door body 3 set on the door hanging plate 2 and the other door body 3, ensuring that the boom 6 maintains a vertical posture under the joint abutting positioning of the upper limiting part 7 and the lower limiting part 8. When the door body 3 is switched to the closed state, the corresponding sections of the corresponding side edges of the door body 3 are matched and fitted, effectively eliminating the gaps between the door bodies 3.

[0024] In actual operation, both the upper limiting part 7 and the lower limiting part 8 are located below the connection between the transmission belt 5 and the boom 6. The upper limiting part 7 is located on the top of the body 1 and close to the transmission belt 5. By reducing the height difference between the upper limiting part 7 and the transmission belt 5, excessive movement of the top of the boom 6 is limited. The top of the boom 6 is fixed to the transmission belt 5. The upper limiting part 7 is located on the movement path in the middle of the boom 6. The bottom of the boom 6 is fixed to the door body 3 through the door hanging plate 2. When the door body 3 is switched to the closed state under the drive of the transmission belt 5, the middle of the boom 6 abuts against the upper limiting part 7, and the bottom of the boom 6 abuts against the lower limiting part 8 formed by the corresponding door body 3 and the side edge of another door body 3. By setting the upper limiting part 7, the lever arm is shortened, thereby effectively reducing the force caused by excessive movement of the transmission belt 5, thus preventing the door body 3 from tilting and ensuring that the door body 3 remains in a vertical position and fits tightly.

[0025] In actual operation, the main body 1 is provided with a limiting member 10 that can abut against the upper part of the boom 6, and the limiting member 10 is provided with a horizontally exposed upper limiting part 7. The limiting member 10 is installed on the top of the main body 1 through a connecting plate 11, so that the upper limiting part 7 of the limiting member 10 is horizontally exposed. The connecting plate 11 is L-shaped and includes a fixing part that fits and is fixed to the top edge of the main body 1 and a connecting part that is fixed to the limiting member 10. The limiting member 10 is telescopically adjustable and installed on the connecting part. The limiting member 10 is elongated, and a mounting hole is provided on the connecting part. One end of the limiting member 10 can be adjusted to pass through the mounting hole and is fixed by bolts, while the other end extends horizontally to form the upper limiting part 7. The end of the limiting member 10 facing the boom 6 forms an upper limiting part 7, and the other end is telescopically inserted into the connecting part of the connecting plate 11 and is telescopically adjustable, so that the boom 6 can fit tightly with the upper limiting part 7 when the door 3 is switched to the closed state, improving positioning reliability. The limiting member 10 is provided with threads, so that the limiting member 10 passes through the connecting part and is fixed by bolts, which not only ensures that the limiting member 10 is firmly installed on the body 1, but also allows the axial position of the limiting member 10 to be adjusted as needed.

[0026] In actual operation, the boom 6 is equipped with an abutment plate 12 (e.g., perpendicular to its direction of movement) Figure 3 As shown, when the door 3 is switched to the closed state, the boom 6 is positioned by contacting the upper limiting part 7 through the contact plate 12. The surface of the contact plate 12 is perpendicular to the axis of the limiting member 10, which effectively improves the reliability of the upper limiting part 7 in limiting the boom 6.

[0027] In actual operation, the boom 6 is fixed to the straight section of the transmission belt 5 by a clamp 9. The clamp 9 and the transmission belt 5 are stacked and fixed together, so that the boom 6 can move horizontally in a vertical position under the drive of the transmission belt 5. The clamp 9 and the transmission belt 5 have a large contact area, which not only serves to fix the boom 6 and the transmission belt 5, but also helps to maintain the posture of the boom 6.

[0028] In actual operation, a linkage component is set between the door hanging plates 2. When any door hanging plate 2 is moved by an external force, the linkage component will drive the other door hanging plate 2 to move in conjunction. Since the door hanging plate 2 subjected to the external force will move precisely due to the arm 6 being positioned against it, the other door hanging plate 2 will also move precisely. This ensures that both door bodies 3 will move precisely and avoids tilting, thus ensuring that the door body 3 closes precisely.

[0029] Understandably, the connection between the transmission belt 5 and the boom 6 can also be located between the upper limiting part 7 and the lower limiting part 8. When the connection is offset due to excessive movement of the transmission belt 5, the boom 6 will maintain its vertical posture because its two ends are simultaneously abutted and positioned by the upper limiting part 7 and the lower limiting part 8. This not only restricts the movement of the transmission belt 5, but also ensures that the door body 3 can maintain its vertical posture, thereby ensuring that the corresponding side edges of the door body 3 fit tightly and effectively eliminate gaps. This should also be regarded as a specific embodiment of this utility model.
