Description

Technical Field

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

[0002] The anti-drop structure for the lower part of the elevator hall door currently used in the market requires the door guide shoe or the lower end of the door panel to have an anti-drop hook, which engages with the sill slide groove to achieve the anti-drop effect when the door panel is hit by an external impact. This type of structure requires an additional bending edge to be added to the door guide shoe or the lower end of the door panel, which is complex in structure. In addition, during the door opening and closing process, due to the distortion and deformation of the door panel, the anti-drop hook is prone to contact and rub against the sill slide groove, generating a sharp and piercing noise. Utility Model Content

[0003] In view of this, in order to overcome the defects of the prior art, the utility model provides an improved anti-slip structure for elevator door panels, which does not require the use of anti-slip hooks and can play an anti-slip effect when the door panel is subjected to external impact.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A structure for preventing an elevator door panel from falling off comprises a door guide shoe assembly and a sill, wherein the sill is provided with a slide groove, the slide groove is arranged at an angle, the door guide shoe assembly comprises a first fixed plate, a second fixed plate and a buffer block, the buffer block is covered on the outside of the second fixed plate, the buffer block is arranged at an angle, the slide groove is used to accommodate the buffer block, and the inclination direction of the slide groove is the same as the inclination direction of the buffer block.

[0006] By tilting the buffer block of the door guide shoe assembly in the slide groove, and tilting the slide groove of the sill, and setting the tilt directions of the two to be consistent, the buffer block itself cooperates with the slide groove of the sill, and when the front of the door panel is impacted by external force, the buffer block of the door guide shoe assembly can form a ratchet-like bite with the slide groove of the sill, making it difficult for the door guide shoe assembly to fall out of the slide groove of the sill, thereby playing an anti-falling effect. In addition, the anti-falling structure of the utility model replaces the original anti-falling hook made of metal material, avoiding the noise caused by the friction between the hook of the anti-falling hook and the slide groove of the sill.

[0007] According to a preferred implementation aspect of the utility model, the first fixing plate is fixedly connected to the lower head of the elevator door panel, and the length direction of the first fixing plate is perpendicular to the length direction of the sill.

[0008] According to a preferred implementation aspect of the utility model, the buffer block includes two mutually parallel first inclined surfaces, the slide slot includes two mutually parallel second inclined surfaces, and the first inclined surface is parallel to the second inclined surface.

[0009] According to a preferred implementation aspect of the utility model, the second slope is inclined from the top surface of the sill and the side of the sill close to the front side of the elevator door panel downward and toward the side close to the back side of the elevator door panel.

[0010] According to a preferred implementation aspect of the utility model, the degree of the acute angle formed between the first inclined surface and the horizontal plane is 45° to 75°.

[0011] According to a preferred implementation aspect of the utility model, the horizontal distance between the two second inclined surfaces is greater than the horizontal distance between the two first inclined surfaces, and there is a gap between the bottom surface of the buffer block and the bottom surface of the slide groove.

[0012] According to the preferred implementation aspects of the utility model, including a first state and a second state, when the anti-slip structure is in the first state, there is a gap between the first inclined surface and the adjacent second inclined surface; when the anti-slip structure is in the second state, one of the two first inclined surfaces fits with an adjacent second inclined surface, and there is a gap between the other first inclined surface and the other adjacent second inclined surface. The first state is when the door panel is in a normal state and is not impacted by external force. During the process of the door panel moving left and right, the buffer block on the door guide shoe assembly will move with the door panel in the slide groove of the sill, and at this time, there is a small gap between the first inclined surface and the corresponding second inclined surface; when in the second state, that is, when the front of the door panel is impacted by external force, under the action of external force, one of the first inclined surfaces of the buffer block will fit with the corresponding second inclined surface.

[0013] According to a preferred implementation aspect of the utility model, the length of the buffer block is 20 to 60 mm.

[0014] According to a preferred implementation aspect of the utility model, the second fixing plate is arranged at an angle, and the inclination direction of the second fixing plate is the same as the inclination direction of the buffer block.

[0015] According to a preferred implementation aspect of the utility model, the slide groove includes a first groove portion and a second groove portion located below the first groove portion, and the buffer block is accommodated in the first groove portion; the first groove portion is inclined and the inclination direction of the first groove portion is the same as the inclination direction of the buffer block. In some embodiments of the utility model, the slide groove can also be set as a first groove portion and a second groove portion, wherein the first groove portion is inclined and the inclination direction is the same as the inclination direction of the buffer block, and the second groove portion is not inclined or the inclination direction of the second groove portion when inclined is different from the inclination direction of the first groove portion.

[0016] Compared with the prior art, the utility model is beneficial in that: the anti-slip structure for elevator door panels of the utility model is to tilt the buffer block of the door guide shoe assembly in the slide groove, and also tilt the slide groove of the sill, and the tilt directions of the two are set to be consistent, without the need to set an anti-slip hook, relying on the cooperation between the buffer block itself and the slide groove of the sill, when the front of the door panel is impacted by external force, the buffer block of the door guide shoe assembly can form a ratchet-type bite with the slide groove of the sill, making it difficult for the door guide shoe assembly to slip out of the slide groove of the sill, thereby playing an anti-slip effect. In addition, the anti-slip structure of the utility model replaces the original anti-slip hook made of metal material, avoiding the noise caused by the friction between the hook of the anti-slip hook and the slide groove of the sill.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solution in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1The anti-slip structure of an elevator door panel in this embodiment includes a door guide shoe assembly 3 and a sill 4, wherein the door guide shoe assembly 3 is fixedly connected to the lower head 2 of the elevator door panel 1, the lower head 2 is fixed to the bottom of the door panel 1, and the sill 4 is located below the door panel 1 and is fixed to the hoistway wall through a sill bracket 5.

[0025] Furthermore, the door guide shoe assembly 3 includes a first fixing plate 31, a second fixing plate 32 and a buffer block 33. The buffer block 33 is covered on the outside of the second fixing plate 32. The first fixing plate 31 is fixedly connected to the lower head 2 and the length direction of the first fixing plate 31 is perpendicular to the length direction of the sill 4. The length of the buffer block 33 is 20 to 60 mm. In this embodiment, the length of the buffer block 33 is preferably 40 mm, which is much smaller than the length of the sill 4. The material of the buffer block 33 in this embodiment is rubber, which can avoid the noise generated by friction between the buffer block 33 and the slide groove 41 when the door panel 1 is hit by external force.

[0026] The second fixing plate 32 and the buffer block 33 are both inclined, and the inclination direction of the second fixing plate 32 is the same as that of the buffer block 33. Specifically, the buffer block 33 includes two mutually parallel first inclined surfaces M1, and the degree of the acute angle formed between the first inclined surfaces M1 and the horizontal plane is 45° to 75°. In this embodiment, the degree of the acute angle is preferably 60°.

[0027] Furthermore, the sill 4 is provided with a chute 41 which is inclined downward from the top thereof, and the chute 41 is used to accommodate the buffer block 33, and the inclination direction of the chute 41 is the same as the inclination direction of the buffer block 33. Specifically, the chute 41 includes two second inclined surfaces M2 which are parallel to each other, and the first inclined surface M1 is parallel to the second inclined surface M2, and the second inclined surface M2 is formed by the top surface of the sill 4 and the sill 4 close to the front surface of the elevator door panel 1 (such as Figure 1 As shown, Figure 1 The left side of the viewing angle is the front side of the elevator door panel 1 , and the side is inclined downward and toward the side close to the back side of the elevator door panel 1 .

[0028] The horizontal distance between the two second inclined surfaces M2 of the slide groove 41 is greater than the horizontal distance between the two first inclined surfaces M1 of the buffer block 33, and there is a gap between the bottom surface of the buffer block 33 and the bottom surface of the slide groove 41. In this embodiment, the anti-slip structure includes a first state and a second state. When the anti-slip structure is in the first state, that is, when the door panel 1 is not impacted by external force in a normal state, when the door panel 1 moves left and right, the buffer block 33 will move with the door panel 1 in the slide groove 41 of the sill 4. At this time, there is a small gap between the first inclined surface M1 and the adjacent second inclined surface M2. When the anti-slip structure is in the second state, that is, when the front side of the door panel 1 is impacted by external force, under the action of the external force, one of the two first inclined surfaces M1 fits with an adjacent second inclined surface M2, so that the buffer block 33 can form a ratchet-like engagement with the slide groove 41 of the sill 4, ensuring that the door guide shoe assembly 3 is difficult to slip out of the slide groove 41 of the sill 4, thereby playing an anti-slip effect; at this time, there is a gap between the other first inclined surface M1 of the two first inclined surfaces M1 and the other adjacent second inclined surface M2.

[0029] Example 2

[0030] See also Figure 2 The anti-slip structure of an elevator door panel in this embodiment includes a door guide shoe assembly 3 and a sill 4, wherein the door guide shoe assembly 3 is fixedly connected to the lower head 2 of the elevator door panel 1, the lower head 2 is fixed to the bottom of the door panel 1, and the sill 4 is located below the door panel 1 and is fixed to the hoistway wall through a sill bracket 5.

[0031] Furthermore, the door guide shoe assembly 3 includes a first fixing plate 31, a second fixing plate 32 and a buffer block 33. The buffer block 33 is covered on the outside of the second fixing plate 32. The first fixing plate 31 is fixedly connected to the lower head 2 and the length direction of the first fixing plate 31 is perpendicular to the length direction of the sill 4. The length of the buffer block 33 is 20 to 60 mm. In this embodiment, the length of the buffer block 33 is preferably 40 mm, which is much smaller than the length of the sill 4. The material of the buffer block 33 in this embodiment is rubber, which can avoid the noise generated by friction between the buffer block 33 and the slide groove 41 when the door panel 1 is hit by external force.

[0032] The second fixing plate 32 and the buffer block 33 are both inclined, and the inclination direction of the second fixing plate 32 is the same as that of the buffer block 33. Specifically, the buffer block 33 includes two mutually parallel first inclined surfaces M1, and the degree of the acute angle formed between the first inclined surfaces M1 and the horizontal plane is 45° to 75°. In this embodiment, the degree of the acute angle is preferably 60°.

[0033] Furthermore, the sill 4 is provided with a slide groove 41 from its top downwards. The slide groove 41 of this embodiment includes a first groove portion 411 and a second groove portion 412. The second groove portion 412 is located below the first groove portion 411. The buffer block 33 is accommodated in the first groove portion 411. The first groove portion 411 is inclined and the inclination direction of the first groove portion 411 is the same as the inclination direction of the buffer block 33. Specifically, the first groove portion 411 includes two second inclined surfaces M2 parallel to each other, and the first inclined surface M1 is parallel to the second inclined surface M2. The second inclined surface M2 is formed by the top surface of the sill 4 and the sill 4 close to the front of the elevator door panel 1 (such as Figure 2 As shown, Figure 2 The left side of the viewing angle is the front side of the elevator door panel 1 , and the side is inclined downward and toward the side close to the back side of the elevator door panel 1 .

[0034] The horizontal distance between the two second inclined surfaces M2 of the first groove portion 411 is greater than the horizontal distance between the two first inclined surfaces M1 of the buffer block 33, and there is a gap between the bottom surface of the buffer block 33 and the bottom surface of the first groove portion 411. In this embodiment, the anti-slip structure includes a first state and a second state. When the anti-slip structure is in the first state, that is, when the door panel 1 is not impacted by external force in a normal state, when the door panel 1 moves left and right, the buffer block 33 will move with the door panel 1 in the first groove portion 411 of the sill 4. At this time, there is a small gap between the first inclined surface M1 and the adjacent second inclined surface M2. When the anti-slip structure is in the second state, that is, when the front side of the door panel 1 is impacted by external force, under the action of the external force, one of the two first inclined surfaces M1 fits with an adjacent second inclined surface M2, so that the buffer block 33 can form a ratchet-like engagement with the first groove portion 411 of the sill 4, ensuring that the door guide shoe assembly 3 is difficult to slip out of the first groove portion 411 of the sill 4, thereby playing an anti-slip effect; at this time, there is a gap between the other first inclined surface M1 of the two first inclined surfaces M1 and the other adjacent second inclined surface M2.

[0035] In addition, in this embodiment, the second groove portion 412 is not arranged at an angle, but is arranged in a vertical direction, which can limit the buffer block 33 to a certain extent, thereby preventing the bottom of the buffer block 33 from contacting the bottom of the second groove portion 412 and affecting the movement of the door panel 1.

[0036] The arrangement of the buffer block 33 and the second fixing plate 32 of the utility model can ensure that even in the worst case, when the buffer block 33 is completely worn out, since the second fixing plate 32 is also arranged at an angle, when the front of the door panel 1 is impacted by external force, the second fixing plate 32 will also form a ratchet-like engagement with the slide groove 41 of the sill 4 to form an anti-slip structure, making it difficult for the door guide shoe assembly 3 to slip out of the slide groove 41, and also playing an anti-slip effect.

[0037] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
