Description

Technical Field

[0001] The utility model relates to the technical field of elevator doors, in particular to an anti-slip elevator door slider. Background Art

[0002] The elevator is a vertical transportation device for multi-story buildings. Its basic structure consists of a car and a counterweight, which are connected by a steel wire rope and driven by a traction wheel driven by an electric motor to move up and down along a vertical guide rail. The upper part of the elevator's floor door and car door are connected and fixed to the door opening and closing device, and the lower part of the elevator's floor door and car door is equipped with a door slider that serves as a guide. The door slider slides in the concave groove of the sill. The door slider slides with the concave groove of the sill to realize the horizontal rail sliding of the elevator's floor door and car door.

[0003] The door slider has a limiting function on the elevator's floor door and car door in a direction perpendicular to the door leaf and a guiding function in the opening and closing direction of the door leaf.

[0004] In the prior art, there is usually an unlimited structure on the body of the door slider, which is made of a square cold-rolled steel plate that is bent and covered with rubber and wear-resistant materials, and cooperates with the concave groove of the sill for guidance.

[0005] However, there is no restriction on the longitudinal movement position of the door slider. When the door leaves of the elevator's floor doors and car doors are deformed due to impact, the door slider is lifted upward and out of the concave groove of the sill, thereby making the lower limit of the door leaves of the elevator's floor doors and car doors invalid. As a result, the door leaves of the elevator's floor doors and car doors lose their lower limit, which can easily cause people to fall into the shaft and affect the personal safety of elevator users and surrounding personnel. Utility Model Content

[0006] The utility model aims to provide an anti-slip elevator door slider to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-slip elevator door slider, including a sill, a slider installed in the middle of the sill, a steel shaft fixedly sleeved in the middle of the slider, limit wheels rotatably sleeved at both ends of the steel shaft, a limit plate arranged at the lower side of the limit wheel, and the limit plate sleeve arranged at the bottom of the slider.

[0008] A spring leaf ring is arranged at the bottom of the limiting disk, a friction ring is arranged on one side of the spring leaf ring, and a bolt is arranged inside the friction ring.

[0009] Preferably, a support platform is fixedly connected to the outer surface of the sill, a mounting plate is fixedly connected to the upper surface of the sliding block, and mounting holes are provided on the surface of the mounting plate.

[0010] Preferably, an upper groove is provided on the top of the sill, and limiting slide bars are fixedly connected to both sides of the lower surface of the mounting plate, and the limiting slide bars are slidably connected to the upper groove.

[0011] Preferably, a lower groove is provided at the lower side of the upper groove, the lower groove is slidably connected to the limiting wheel, and limiting plates are provided at the upper and lower sides of the limiting disk.

[0012] Preferably, one side of the limit plate is welded and fixed to the sill, and a buffer is fixedly connected to one side of the limit plate, and the buffer is arranged equidistantly with respect to the surface of the limit plate.

[0013] Preferably, universal balls are provided on both sides of the limit plate and are slidably connected to the universal balls, and one side of the universal ball is fixedly connected to the sill.

[0014] Preferably, the slider is slidably connected to the sill, a threaded hole is provided at the bottom of the slider, and the bolt is threadedly connected to the threaded hole.

[0015] Preferably, a mounting groove is provided at the bottom of the limiting plate, the spring leaf ring is sleeved in the mounting groove, and the bolt is sleeved in the friction ring and the spring leaf ring.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. By fixing a support platform on the outer surface of the sill, the support platform is fixedly connected to the ground to reduce the damage to the sill caused by external impact, thereby preventing the sill from being deformed too much and causing the slider to detach from the sill. A mounting plate is fixedly connected to the upper surface of the slider, and mounting holes are provided on the surface of the mounting plate. The provided mounting holes facilitate the fixed connection between the mounting plate and the door panel. A limit slide is fixedly connected to the bottom of the mounting plate, and the limit slide slides in the upper groove. The upper groove is T-shaped, thereby limiting the limit slide, thereby limiting the mounting plate, and then limiting the slider. The lower groove is also T-shaped, thereby limiting the limit wheel. The limit wheel is rotatably sleeved on both ends of the steel shaft, so that the steel shaft limits the slider again to prevent the slider from detaching from the sill.

[0018] 2. By putting the bolt into the friction ring and the spring leaf ring, twisting the bolt at this time to make the bolt move toward the inside of the threaded hole opened at the bottom of the slider, the bolt will drive the friction ring to move, so that the friction ring squeezes the spring leaf ring, and the spring leaf ring is drum-shaped. After the spring leaf ring is deformed by force, a reverse elastic force is generated, which will push the friction ring to move in the opposite direction, thereby making the connection between the bolt and the slider tighter, so that the limit plate is fixedly installed at the bottom of the slider, and a buffer is fixedly installed on one side of the limit plate. The buffer acts on the limit plate when it is hit. The buffer reduces the possibility of the sill being deformed due to impact. In addition, the buffer and the limit plate limit the limit plate, so that the limit plate further limits the slider connected to it, thereby avoiding that when the door leaves of the elevator's floor door and car door are deformed due to impact, the slider is lifted up and off the sill, thereby making the lower limit of the door leaves of the elevator's floor door and car door invalid, causing the door leaves of the elevator's floor door and car door to lose the lower limit, which may easily cause people to fall into the shaft and affect the personal safety of elevator users and surrounding personnel.

A spring leaf ring 6 is arranged at the bottom of the limiting disk 5, a friction ring 7 is arranged on one side of the spring leaf ring 6, and a bolt 8 is sleeved in the friction ring 7.

[0030] The sill 1 limits the slider 2 during the sliding process, thereby initially preventing it from escaping from the sill 1. A steel shaft 3 is fixedly sleeved in the middle of the slider 2, and limiting wheels 4 are rotatably sleeved at both ends of the steel shaft 3. The limiting wheels 4 move inside the sill 1, thereby limiting the slider 2 again. The steel shaft 3 is relatively strong, so it can resist partial impact, so that the limiting wheel 4 can slide normally, and the bolt 8 is twisted toward the inside of the lower side of the slider 2 to squeeze the friction ring 7, so that the friction ring 7 squeezes the spring leaf ring 6 to deform, so that the spring leaf ring 6 produces a reverse elastic force, so that the connection between the bolt 8 and the slider 2 is tighter, and the limiting plate 5 is fixed to the bottom of the slider 2, and the slider 2 is limited again, thereby preventing the slider 2 from being lifted up and escaping from the sill 1, thereby making the limit of the lower part of the door leaf of the elevator floor door and the car door invalid, causing the door leaf of the elevator floor door and the car door to lose the lower limit.

[0031] Embodiment 2

[0032] On the basis of Example 1, a support platform 9 is fixedly connected to the outer surface of the sill 1, and a mounting plate 10 is fixedly connected to the upper surface of the slider 2. A mounting hole 11 is provided on the surface of the mounting plate 10. The support platform 9 fixedly supports the sill 1. The mounting holes 11 provided on the surface of the mounting plate 10 facilitate the installation of the mounting plate 10 and the door panel. An upper groove 12 is provided on the top of the sill 1, and limiting slides 13 are fixedly connected to both sides of the lower surface of the mounting plate 10. The limiting slide 13 is slidably connected to the upper groove 12, and the limiting slide 13 slides in the upper groove 12 so that the limiting slide 13 limits the slider 2. A lower groove 14 is provided on the lower side of the upper groove 12, and the lower groove 14 is slidably connected to the limiting wheel 4. Limiting plates 15 are arranged on the upper and lower sides of the limiting disk 5, and the limiting wheel 4 slides in the lower groove 14 to further limit the slider 2.

[0033] By fixing a support platform 9 on the outer surface of the sill 1, the support platform 9 is fixedly connected to the ground to reduce the damage to the sill 1 caused by external impact, thereby preventing the sill 1 from being deformed too much and causing the slider 2 to separate from the sill 1. A mounting plate 10 is fixedly connected to the upper surface of the slider 2, and a mounting hole 11 is opened on the surface of the mounting plate 10. The provided mounting hole 11 facilitates the fixed connection between the mounting plate 10 and the door panel. A limiting slide bar 13 is fixedly connected to the bottom of the mounting plate 10, and the limiting slide bar 13 slides in the upper groove 12. The upper groove 12 is T-shaped, thereby limiting the limiting slide bar 13, thereby limiting the mounting plate 10, and then limiting the slider 2. The lower groove 14 is also T-shaped, thereby limiting the limiting wheel 4. The limiting wheel 4 is rotatably sleeved on both ends of the steel shaft 3, so that the steel shaft 3 limits the slider 2 again to prevent the slider 2 from separating from the sill 1.

[0034] Embodiment 3

[0035] On the basis of the second embodiment, one side of the limit plate 15 is welded and fixed to the sill 1, and a buffer 16 is fixedly connected to one side of the limit plate 15 and the buffer 16 is arranged equidistantly about the surface of the limit plate 15. The limit plate 15 is installed inside the sill 1 to limit the limit plate 5. Universal balls 17 are provided on both sides of the limit plate 5 and are slidably connected to the universal balls 17. One side of the universal ball 17 is fixedly connected to the sill 1, and the rolling ball of the universal ball 17 is slidably connected to the limit plate 5, so that the slider 2 is easier to move inside the sill 1. Sliding, the slider 2 is slidably connected to the sill 1, a threaded hole 18 is provided at the bottom of the slider 2, and the bolt 8 is threadedly connected to the threaded hole 18. The limit plate 5 is fixedly installed by the threaded connection between the bolt 8 and the threaded hole 18. A mounting groove 19 is provided at the bottom of the limit plate 5, and the spring leaf ring 6 is sleeved in the mounting groove 19. The bolt 8 is sleeved in the friction ring 7 and the spring leaf ring 6. The friction ring 7 squeezes the spring leaf ring 6 in the mounting groove 19, so that the spring leaf ring 6 generates a reverse elastic force to prevent the bolt 8 from loosening.

[0036] By sleeved the bolt 8 in the friction ring 7 and the spring leaf ring 6, the bolt 8 is twisted at this time to make the bolt 8 move toward the inside of the threaded hole 18 opened at the bottom of the slider, the bolt 8 will drive the friction ring 7 to move, so that the friction ring 7 squeezes the spring leaf ring 6, and the spring leaf ring 6 is drum-shaped. After the spring leaf ring 6 is deformed by force, a reverse elastic force is generated, which will push the friction ring 7 to have a tendency to move in the opposite direction, thereby making the connection between the bolt 8 and the slider 2 tighter, so that the limit plate 5 is fixedly installed at the bottom of the slider 2, and a buffer 16 is fixedly installed on one side of the limit plate 15. The buffer 16 buffers the limit plate 5 when it is impacted, reducing the possibility of deformation of the sill 1 due to the impact. In addition, the buffer 16 and the limit plate 15 limit the limit plate 5, so that the limit plate 5 limits the slider 2 connected thereto.

[0037] In actual use, by fixing the support platform 9 on the outer surface of the sill 1, the support platform 9 is fixedly connected to the ground to reduce the damage of the sill 1 caused by external impact, thereby preventing the sill 1 from being deformed too much and the slider 2 from being separated from the sill 1. The upper surface of the slider 2 is fixedly connected with a mounting plate 10, and the surface of the mounting plate 10 is provided with a mounting hole 11. The mounting hole 11 is provided to facilitate the fixed connection between the mounting plate 10 and the door panel. The bottom of the mounting plate 10 is fixedly connected with a limited slide bar 13, and the limited slide bar 13 is in the upper groove 12. The upper groove 12 is T-shaped, so as to limit the limit slide bar 13, thereby limiting the mounting plate 10, and then limiting the slider 2. The lower groove 14 is also T-shaped, so as to limit the limit wheel 4. The limit wheel 4 is rotatably sleeved on both ends of the steel shaft 3, so that the steel shaft 3 limits the slider 2 again to prevent the slider 2 from leaving the sill 1. By sleeve the bolt 8 in the friction ring 7 and the spring leaf ring 6, the bolt 8 is twisted at this time to make the bolt 8 move to the inside of the threaded hole 18 opened at the bottom of the slider, and the bolt 8 will drive the friction ring 7 The friction ring 7 is moved, and the friction ring 7 squeezes the spring coil 6, and the spring coil 6 is drum-shaped. After the spring coil 6 is deformed by force, a reverse elastic force is generated, which will push the friction ring 7 to have a tendency to move in the opposite direction, thereby making the connection between the bolt 8 and the slider 2 tighter, so that the limit plate 5 is fixedly installed at the bottom of the slider 2, and a buffer 16 is fixedly installed on one side of the limit plate 15. The buffer 16 buffers the limit plate 5 when it is hit, reducing the possibility of deformation of the sill 1 due to the impact. In addition, the buffer 16 and the limit plate 15 limit the limit plate 5, so that the limit plate 5 further limits the slider 2 connected thereto, thereby avoiding that when the door leaves of the elevator's floor door and car door are deformed due to the impact, the slider 2 is lifted up and out of the sill 1, thereby making the limit of the lower part of the door leaf of the elevator's floor door and car door invalid, causing the door leaves of the elevator's floor door and car door to lose the lower limit, which is easy to cause an accident of people falling into the shaft, affecting the personal safety of elevator users and surrounding personnel.
