Description

Technical Field

[0001] The invention relates to the technical field of rolling door machines, in particular to a novel self-locking electric rolling door machine frame plate with a self-locking function. Background Art

[0002] Electric rolling door machines have long been widely used in shops of all sizes. Since electric rolling door machines have a certain weight, when encountering sudden situations such as power outages and motor failures during the ascent or descent process, the electric rolling door machines are likely to fall out of control. Such a heavy rolling door machine can easily hit people or objects when it falls, which poses an unsafe factor. Although many electric rolling doors in the prior art have adopted anti-fall functions, most of them are improvements in controlling the motor and use electronic anti-fall. In the event of power outages and other situations, there will still be uncontrollable situations. Therefore, the problem of electric rolling door machines falling out of control has not been completely solved. Summary of the invention

[0003] In order to solve the defects and problems existing in the prior art of preventing an electric rolling door machine from falling, a new self-locking electric rolling door machine frame plate is provided.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a new type of self-locking electric rolling door machine frame plate of the present invention includes a frame plate, one side of the frame plate is connected to a motor shaft, and the other side of the frame plate is provided with an active rotating disk, and the motor shaft and the active rotating disk are driven and connected by a chain or a belt; a self-locking mechanism is connected to the active rotating disk, and the self-locking mechanism includes a self-locking shaft, and the self-locking shaft is fixed on the frame plate, the self-locking shaft passes through the center position of the active rotating disk, and is in sliding cooperation with the active rotating disk, and a self-locking gear is fixed on the self-locking shaft, and the self-locking gear cooperates with two passive rotating disks, the two passive rotating disks are both semicircular structures, and the two passive rotating disks are symmetrically distributed to form a disc structure.

[0005] The inner ring of the passive rotating disk is provided with meshing teeth, and the passive rotating disk is meshed with the self-locking gear on the self-locking shaft through the meshing teeth. Two fixed columns are provided between the two passive rotating disks, and the fixed columns are fixed on the main shaft rotating disk and keep synchronous rotation with the main shaft rotating disk. A passive rotating cover is provided at the upper end of the passive rotating disk, and the passive rotating cover covers the outer end of the passive rotating disk. A spring is pressed inwardly on the passive rotating cover, and the other end of the spring is pressed on the outer end of the passive rotating disk. Limiting grooves are also provided on both sides of the passive rotating disk, and the limiting grooves are matched with limiting columns.

[0006] Limiting grooves are also arranged on both sides of the passive rotating disk, and limiting posts are matched on the limiting grooves.

[0007] The limiting column is fixed on the passive rotating cover.

[0008] The reverse transmission precise self-locking structural device of the present invention is self-locking through the meshing and separation between the self-locking gear on the self-locking shaft and the meshing teeth on the two passive rotating disks. When the active rotating disk rotates clockwise or counterclockwise, under the pressure of the two fixed columns, the self-locking gear on the self-locking shaft separates from the meshing teeth on the two passive rotating disks, and the active rotating disk drives the passive rotating disk to rotate clockwise or counterclockwise. When the active rotating disk does not rotate, under the elastic pressure of the spring, the self-locking gear on the self-locking shaft meshes with the meshing teeth on the two passive rotating disks, and the passive rotating disk is self-locked and fixed to the self-locking shaft, and the passive rotating cover is directly connected to the drum of the rolling door machine, and the rolling door machine is directly physically self-locked, which solves the problems of power outages, broken transmission chains, and lightning strikes on electronic lock rectifier silicon. The use of this mechanical self-locking structure has high safety and reliability, and the use of gear transmission has the advantages of precise self-locking and the like. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] A novel self-locking electric rolling door machine frame plate of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0010] Figure 1 It is a structural schematic diagram of a frame plate of a novel self-locking electric rolling door machine of the present invention;

[0011] Figure 2 The present invention is a schematic structural diagram of a self-locking mechanism of a frame plate of a novel self-locking electric rolling door machine. DETAILED DESCRIPTION

[0012] like Figure 1 and Figure 2 As shown, a new self-locking electric rolling door machine frame plate of the present invention includes a frame plate 0, a motor shaft 5 is connected to one side of the frame plate 0, and an active rotating disk 1 is provided on the other side of the frame plate 5. The motor shaft 1 and the active rotating disk 5 are driven and connected by a chain or a belt 51, that is, the motor shaft 1 drives the active rotating disk 5 to rotate through the chain or the belt 51. A self-locking mechanism is connected to the active rotating disk 1, and the self-locking mechanism includes a self-locking shaft 2. The self-locking shaft 2 is fixed on the frame 0. The center position of the active rotating disk 1 has a through hole (not shown in the figure). The self-locking shaft 2 passes through the through hole at the center position of the active rotating disk 1. The self-locking shaft 2 and the active rotating disk 1 are in sliding cooperation, that is, the active rotating disk 1 is driven to rotate by the motor, and the self-locking shaft 2 is in a fixed state. A self-locking gear 21 is fixed on the self-locking shaft 2, and the self-locking gear 21 cooperates with two passive rotating disks 3.

[0013] like Figure 1 and Figure 2As shown, the two passive rotating disks 3 are both semicircular structures, and the two passive rotating disks 3 are symmetrically distributed to form a disc structure. The inner ring of the passive rotating disk 3 is provided with meshing teeth 31, and the passive rotating disk 3 meshes with the self-locking gear 21 on the self-locking shaft 2 through the meshing teeth 31. Two fixed columns 11 are provided between the two passive rotating disks 3, that is, two fixed columns 11 are sandwiched in the gap between the two passive rotating disks 3, and the two fixed columns 11 are distributed on both sides of the passive rotating disk 3. The fixed columns 11 are fixed on the main shaft rotating disk 1, and the fixed columns 11 rotate synchronously with the main shaft rotating disk 1. A passive rotating cover 4 is provided at the upper end of the passive rotating disk 3, and the passive rotating cover 4 covers the outer end of the passive rotating disk 3. A spring 41 is pressed inwardly on the passive rotating cover 4, and the other end of the spring 41 is pressed on the outer end of the passive rotating disk 3. A spring hole 33 is provided at the outer end of the passive rotating disk 3, and one end of the spring 41 is pressed by the passive rotating cover 4, and the other end of the spring 41 is pressed on the passive rotating disk 3. The passive rotating disk 3 is also provided with limiting grooves 32 on both sides, and the limiting grooves 32 are matched with limiting posts 42. The limiting posts 42 are fixed on the passive rotating cover 4, and the limiting posts 42 and the passive rotating cover 4 protect synchronous movement.

[0014] like Figure 1 and Figure 2 As shown, when the main shaft rotating disk 1 rotates, the main shaft rotating disk 1 and the two fixed columns 11 all rotate. At this time, the two fixed columns 11 are pressed on the upper and lower parts of the two passive rotating disks 3 respectively, and the upper or lower passive rotating disk 3 is driven to rotate by the fixed column 11 on the right or left side. The two passive rotating disks 3 compress the spring 41 under the pressure of the two fixed columns 11, so that the meshing teeth 31 of the passive rotating disk 3 are separated from the self-locking gear 21 on the self-locking shaft 2. At this time, the passive rotating cover 4 and the passive rotating disk 3 are driven to rotate by the main shaft rotating disk 1, and the self-locking shaft 2 is not self-locking. When the main shaft rotating disk 1 stops after rotating, since the fixed column 11 stops rotating, the fixed column 11 has no pressure on the passive rotating disk 3, and the passive rotating disk 3 is pressed inwardly under the elastic force of the spring 41, so that the meshing teeth 31 of the passive rotating disk 3 mesh with the self-locking gear 21 on the self-locking shaft 2. At this time, the passive rotating cover 4 and the passive rotating disk 3 are both fixed to the self-locking shaft 2, that is, when the motor of the rolling door machine stops rotating, the passive rotating disk 3 is disengaged from the main shaft rotating disk 1, and is self-locked and fixed by the self-locking shaft 2, thereby having a safe self-locking and anti-falling function.

[0015] To sum up, compared with the prior art, the reverse transmission precise self-locking structural device of the present invention is self-locking through the meshing and separation between the self-locking gear on the self-locking shaft and the meshing teeth on the two passive rotating disks. When the active rotating disk rotates clockwise or counterclockwise, under the pressure of the two fixed columns, the self-locking gear on the self-locking shaft separates from the meshing teeth on the two passive rotating disks, and the active rotating disk drives the passive rotating disk to rotate clockwise or counterclockwise. When the active rotating disk does not rotate, under the elastic pressure of the spring, the self-locking gear on the self-locking shaft meshes with the meshing teeth on the two passive rotating disks, and the passive rotating disk is self-locked and fixed to the self-locking shaft, and the passive rotating cover is directly connected to the drum of the rolling door machine, and the rolling door machine is directly physically self-locked, which solves the problems of power outages, transmission chain breakage, and electronic lock rectifier silicon being struck by lightning. The use of this mechanical self-locking structure has high safety and reliability, and the use of gear transmission has the advantages of precise self-locking and the like.

[0016] The present invention has been described illustratively and not restrictively according to the embodiments of the present invention, but it should be understood that changes and / or modifications may be made by those skilled in the art without departing from the relevant protection scope defined by the claims.
