[0041] like Figure 1-Figure 3 As shown, this embodiment provides a door machine system, including a door machine beam 1, a door body 2, a roller mechanism 3 and an electric lock mechanism 4, wherein a guide rail 11 is arranged on the door machine beam 1; the roller mechanism 3 includes a mounting plate 31 and at least two rollers 32, the rollers 32 are rotatably mounted on the mounting plate 31 and cooperate with the guide rail 11, the door body 2 is mounted on the mounting plate 31, and the mounting position of the door body 2 on the mounting plate 31 is located on the perpendicular bisector of the connecting line of at least two rollers 32; the electric lock mechanism 4 includes a movable plate 41 and a locking member 42, the movable plate 41 is mounted on the door machine beam 1, a locking groove 411 is arranged on the movable plate 41, the locking member 42 is mounted on the mounting plate 31, and the roller 32 can move along the guide rail 11 so that the locking member 42 is locked with the movable plate 41.

[0042] In short, in the door machine system provided by this embodiment, the installation position of the door body 2 on the mounting plate 31 is located on the perpendicular bisector of the connecting line of at least two rollers 32, so that the weight of the door body 2 is evenly transferred to each roller 32, so that the rollers 32 are evenly stressed, thereby ensuring that the rollers 32 and the guide rails 11 are stably matched, thereby ensuring that the mounting plate 31 can remain parallel to the guide rails 11, and the mounting plate 31 and the locking member 42 thereon can move smoothly, thereby ensuring that the locking member 42 and the locking groove 411 on the movable plate 41 are accurately locked, thereby reducing the failure rate and ensuring the stability and safety of the door machine system.

[0043] Preferably, if Figure 1 As shown, there are two door bodies 2, and the driving mechanism 5 can drive the two door bodies 2 to move closer to or away from each other to achieve the door closing or door opening function.

[0044] Optionally, there are several roller mechanisms 3 , and one door body 2 cooperates with the guide rail 11 through several roller mechanisms 3 to ensure that the door body 2 can move stably along the guide rail 11 .

[0045] For example, Figure 1 As shown, a door body 2 cooperates with the guide rail 11 through two roller mechanisms 3, which can ensure that the door body 2 moves smoothly along the guide rail 11 on the one hand, and facilitate the adjustment of the levelness and height of the door body 2 through the two roller mechanisms 3 on the other hand.

[0046] Preferably, if Figure 4 Combination Figure 2 As shown, in order to ensure that the roller mechanism 3 moves smoothly along the guide rail 11, the roller mechanism 3 also includes an anti-tipping wheel 33, which is rotatably mounted on the mounting plate 31, and the guide rail 11 is located between the roller 32 and the anti-tipping wheel 33, and the anti-tipping wheel 33 abuts against the guide rail 11 to ensure the stability of the cooperation between the roller mechanism 3 and the guide rail 11. Exemplarily, the roller 32 is located above the anti-tipping wheel 33, the roller 32 cooperates with the guide rail 11, and the anti-tipping wheel 33 abuts against the lower surface of the guide rail 11 to ensure the stability of the mounting plate 31, so that the mounting plate 31 remains parallel to the guide rail 11, thereby ensuring that the locking member 42 is locked with the locking groove 411.

[0047] Optionally, the position of the anti-tipping wheel 33 on the mounting plate 31 is adjustable, so that the position of the anti-tipping wheel 33 can be adjusted according to the thickness of the guide rail 11 and the matching requirements between the roller 32 and the anti-tipping wheel 33 .

[0048] For example, Figure 5 Combination Figure 4 As shown, the mounting plate 31 is provided with a first elongated hole 311, and the anti-tipping wheel 33 is fixedly mounted at the first elongated hole 311 by a fastener. Preferably, the first elongated hole 311 is tilted to adjust the height and left and right position of the anti-tipping wheel 33 as needed.

[0049] Furthermore, if Figure 5 As shown, in order to facilitate the installation of the door body 2 on the mounting plate 31, the roller mechanism 3 also includes a door body hanger 34, the door body 2 is installed on the door body hanger 34, the door body hanger 34 is installed on the mounting plate 31, and the installation position of the door body hanger 34 on the mounting plate 31 is located on the perpendicular bisector of the connecting line of at least two rollers 32.

[0050] Preferably, the door body hanger 34 can be lifted and rotated relative to the mounting plate 31 to adjust the height and levelness of the door body 2. Optionally, the roller mechanism 3 further includes a connecting member 35, which is used to connect the door body hanger 34 and the mounting plate 31.

[0051] For example, Figure 5 As shown, the connecting member 35 includes a first connecting portion 351 and a second connecting portion 352 which are perpendicular to each other. The first connecting portion 351 is installed on the mounting plate 31 and can be raised and lowered relative to the mounting plate 31 to adjust the height of the door body 2; the second connecting portion 352 is rotatably connected to the door body hanger 34 so that the door body hanger 34 can rotate relative to the mounting plate 31 to adjust the horizontality of the door body 2.

[0052] Furthermore, the first connecting portion 351 is located on the perpendicular bisector of the connecting line of at least two rollers 32, so as to ensure that the weight of the door body 2 is evenly transferred to each roller 32 through the first connecting portion 351, so that each roller 32 is evenly stressed, thereby ensuring that the mounting plate 31 is parallel to the guide rail 11, thereby improving the accuracy of the position of the locking member 42 and reducing the failure rate of the electric control lock mechanism 4. In this embodiment, two rollers 32 are installed on one mounting plate 31, and the first connecting portion 351 is located on the perpendicular bisector of the connecting line of the two rollers 32.

[0053] Exemplarily, the first connection part 351 includes an adjusting screw, a gasket and a nut, the adjusting screw is passed through the gasket, the nut is threadedly connected to the adjusting screw, and the nut is located above the gasket, and the lower end of the adjusting screw is fixedly connected to the second connection part 352. An escape position for installing the adjusting screw is provided on the mounting plate 31. When the first connection part 351 is assembled with the mounting plate 31, the adjusting screw passes through the escape position, and the gasket is blocked above the escape position. By adjusting the position of the nut on the adjusting screw, the position of the second connection part 352 is changed, that is, the height of the door body hanger 34 is changed.

[0054] Optionally, in order to ensure the connection strength between the door hanger 34 and the mounting plate 31 , the door hanger 34 and the mounting plate 31 are fixedly connected by fasteners on both sides of the connecting member 35 .

[0055] Specifically, Figure 5 As shown, a second elongated hole 312 is provided on the mounting plate 31, and the second elongated hole 312 extends in the vertical direction. The two second elongated holes 312 are symmetrically arranged on both sides of the avoidance position, and a through hole corresponding to the second elongated hole 312 is provided on the door body hanger 34. The cooperation of the two second elongated holes 312 enables the door body hanger 34 to be fixedly connected to the mounting plate 31 by fasteners when the door body hanger 34 rotates relative to the mounting plate 31.

[0056] Preferably, if Figure 9-10 As shown, the electric lock mechanism 4 further includes a fixed plate 43 and a movable plate driver 44. The fixed plate 43 is mounted on the door machine beam 1. The movable plate 41 is mounted on the fixed plate 43 in a liftable manner. The movable plate driver 44 is used to move the movable plate 41 upward relative to the fixed plate 43. In addition, the movable plate 41 can be lowered under the action of gravity so that the movable plate 41 has a locked position and an unlocked position. The movable plate driver 44 drives the movable plate 41 to rise so that the movable plate 41 is in the unlocked position, and the roller 32 can move in a direction away from the movable plate 41 to disengage the locking member 42 from the lock slot 411, so that the door body 2 is in an open state.

[0057] Exemplarily, the movable plate driver 44 is an electromagnet. When the electromagnet is powered on, it can attract the movable plate 41 to move upward to unlock it. When the electromagnet is powered off, the magnetic force of the electromagnet disappears, and the movable plate 41 can fall under the action of gravity.

[0058] In order to automatically control the opening and closing of the door body 2, Figure 1 and 2 As shown, the door machine system also includes a driving mechanism 5, the output end of the driving mechanism 5 is transmission-connected to the roller mechanism 3, and can drive the roller mechanism 3 to move along the guide rail 11, and the driving mechanism 5 cooperates with the movable plate driver 44 to ensure that when the driving mechanism 5 drives the roller mechanism 3 to move, the locking member 42 can be locked or disengaged with the locking groove 411.

[0059] Preferably, the output end of the driving mechanism 5 is transmission-connected to at least one roller mechanism 3 , and then all the roller mechanisms 3 are driven to move along the guide rail 11 through the connection between the roller mechanisms 3 .

[0060] Preferably, the driving mechanism 5 includes a door body driver 51, a driving wheel 52, a driven wheel 53 and a synchronous belt 54. The driving wheel 52 and the driven wheel 53 are arranged at intervals. The synchronous belt 54 is wound around the driving wheel 52 and the driven wheel 53. The mounting plate 31 is fixedly connected to the synchronous belt 54. The output end of the door body driver 51 is transmission connected to the driving wheel 52 and can drive the synchronous belt 54 to rotate, so that the mounting plate 31 moves.

[0061] Furthermore, if Figure 2 Combination Figure 4 As shown, the roller mechanism 3 further includes a synchronous belt clamp 36 , which is mounted on the mounting plate 31 , and the synchronous belt clamp 36 can be clamped and fixed on the synchronous belt 54 .

[0062] In this embodiment, there are two door bodies 2, each of which is connected to at least two roller mechanisms 3, and the electric lock mechanism 4 is located between the two door bodies 2. The two roller mechanisms 3 adjacent to each other on both sides of the electric lock mechanism 4 are both installed with locking members 42, and both sides of the movable plate 41 are provided with locking grooves 411. The driving mechanism 5 drives the roller mechanism 3 to move along the guide rail 11, and the locking members 42 on the roller mechanism 3 can be locked with the locking grooves 411 on the same side. Two roller mechanisms 3 are connected to each door body 2, wherein the roller mechanism 3 close to the electric lock mechanism 4 on one side of the door body 2 is clamped to the lower half of the annular synchronous belt 54 by the synchronous belt clamp 36, and the roller mechanism 3 close to the electric lock mechanism 4 on the other side of the door body 2 is clamped to the upper half of the annular synchronous belt 54 by the synchronous belt clamp 36.

[0063] This embodiment provides two types of roller mechanisms 3, such as Figure 6 and Figure 4The first roller mechanism 3 shown in the figure has a locking member 42 and a synchronous belt clamp 36 installed on the mounting plate 31 of the roller mechanism 3. The roller mechanism 3 is fixedly connected to the synchronous belt 54 of the driving mechanism 5. The roller mechanism 3 acts as an active member to drive the door body 2 to move along the guide rail 11. Figure 7-Figure 8 The second type of roller mechanism 3 shown is not provided with a synchronous belt clamp 36 , and the roller mechanism 3 serves as a driven member to enable the door body 2 to move smoothly.

[0064] Furthermore, if Figure 9-10 As shown, in order to realize the locking function of the door body 2 when the door is open and the locking function of the door body 2 when the door is closed, the electric control lock mechanism 4 also includes a positioning member 45 and a locking plate 46. The positioning member 45 is installed on the movable plate 41, and the locking plate 46 is rotatably installed on the fixed plate 43. A locking hook 461 is provided on the locking plate 46, and the locking hook 461 can be locked with the locking member 42.

[0065] The locking plate 46 has a first position locked with the locking member 42 and a second position supported under the positioning member 45, that is, the locking plate 46 has two functions. When the locking plate 46 is in the first position, that is, the door body 2 is in a closed state, the locking plate 46 is locked with the locking member 42, and the movable plate 41 and the locking member 42 are also in a locked state, thereby realizing double mechanical locking in the closed state; when the locking plate 46 is in the second position, that is, the door body 2 is in an open state, the locking plate 46 can support the bottom of the positioning member 45 to prevent the movable plate 41 from falling, thereby realizing mechanical locking in the open state.

[0066] like Fig. 9 As shown, when it is necessary to control the door body 2 to close, the driving mechanism 5 drives the roller mechanism 3 to drive the door body 2 and the locking member 42 to move in the direction close to the electric control lock mechanism 4 until the door body 2 is in a closed state. During this process, the locking member 42 can push the locking plate 46 to rotate to the first position of the locking plate 46. At this time, the locking member 42 is locked with the locking hook 461 on the locking plate 46, and the locking member 42 is located below the locking groove 411; since the locking plate 46 can no longer continue to support the positioning member 45 on the movable plate 41, the movable plate 41 falls and causes the locking groove 411 to lock with the locking member 42, thereby realizing double mechanical locking in the closed state.

[0067] like Fig.10As shown, when it is necessary to control the door body 2 to open, the movable plate driver 44 drives the movable plate 41 to move upward, and the lock slot 411 is disengaged from the locking member 42. At the same time, the driving mechanism 5 drives the roller mechanism 3 to drive the door body 2 and the locking member 42 to move in a direction away from the electric control lock mechanism 4. The locking plate 46 rotates to both sides under the action of its own gravity to the second position of the locking plate 46. At this time, the locking member 42 is disengaged from the lock hook 461, and the locking plate 46 is supported under the positioning member 45 of the movable plate 41 to prevent the movable plate 41 from falling, thereby realizing mechanical locking in the open door state.

[0068] In order to make the movable plate driver 44 and the driving mechanism 5 work in conjunction, the electric lock mechanism 4 also includes a travel switch 47, which abuts against the upper edge of the movable plate 41. When the movable plate 41 moves upward, the travel switch 47 can be triggered, and then the driving mechanism 5 drives the roller mechanism 3 to drive the door body 2 and the locking member 42 away from the electric lock mechanism 4, thereby realizing the door opening function.

[0069] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
