Referring to fig. 1 to 4, a roller type sliding door structure comprises a door body 1, a hinge 2, a hinge spring 3, a roller bracket assembly 4 and a door body hinge support 5, wherein the door body 1 is installed on a front plate 11 of an applied product, the door body hinge support 5 is fixedly arranged at the lower end of the side edge of the door body 1, the roller bracket assembly 4 is fixedly arranged on a bottom plate 12 of the applied product, the hinge 2 is connected with the door body hinge support 5, two ends of the hinge spring 3 are respectively connected with the hinge 2 and the roller bracket assembly 4, the hinge 2 slides on the roller bracket assembly 4, and the bottom surface of the hinge 2 is provided with an inclined smooth plane 21.
In this embodiment, the roller type sliding door structure can be applied to household appliances, for example, a microwave oven, a micro-steaming and baking integrated machine, a steaming oven, a steam box, an oven, a microwave air fryer, a fryer and the like, and the sliding door structure of this embodiment needs to be installed one on each of two sides of the door body in practical application, and the specific implementation mode is: with a body hinge support welded fastening on door body side, hinge one end is connected on a body hinge support, the hinge spring is being connected to the other end, the hinge spring is connected with gyro wheel bracket component again, and gyro wheel bracket component rigid, the gyro wheel of the adjacent gyro wheel bracket component in hinge bottom surface this moment, so door body hinge support can drive the hinge and slide on gyro wheel of gyro wheel bracket component when opening the door, and then tensile hinge spring, from this hinge spring can produce the reverse pulling force of closing the door, because the hinge bottom surface is the smooth plane of slope, so the hinge can be more smooth and easy free from extraneous sound when sliding, the plane of slope can produce the pulling force of closing the door that frictional force produced to confront the hinge spring at the hinge slip in-process, just so realized the effect that arbitrary angle is.
The drop-down door structure of this embodiment is simple and easy to make, and the step is simple when actually installing, consequently can reduce the cost of manufacture of drop-down door, also further reduces the manufacturing cost of the product of the drop-down door structure of this embodiment of application.
Optionally, the roller bracket assembly 4 includes a roller bracket 41 and a roller 42 disposed on the roller bracket 41, two ends of the roller bracket 41 are respectively connected to the hinge spring 3 and the door body 1, and the bottom surface of the hinge 2 slides close to the roller 42. In the structure, the roller bracket is fixedly arranged on the bottom surface of the product, one end of the roller bracket is movably connected with the door body, and the door body can smoothly rotate and cannot be separated from the product when being opened and closed; the other end of the roller bracket is provided with a through hole for enabling the hook at the top end of the hinge spring to hook the through hole so as to connect the hinge spring and the roller bracket; the gyro wheel support upwards is equipped with the gyro wheel, and the adjacent gyro wheel of hinge bottom surface, and the hinge will slide on the gyro wheel during switch door, has guaranteed the smooth and easy of switch door.
Optionally, the end of the hinge 2 is provided with a draw hook 20, the end of the roller bracket 41 is provided with a through hole 40, the two ends of the hinge spring 3 are both provided with a hook ring 30, and the hook ring 30 is hooked on the draw hook 20 and the through hole 40 so that the hinge spring 3 is respectively connected with the hinge 2 and the roller bracket 41. Through above-mentioned structure, the specification of hinge spring just can be changed wantonly, can use the spring of different specifications according to practical application's product difference, also conveniently changes when the not enough condition of elasticity appears after the long-time use of hinge spring moreover.
Optionally, an auxiliary arc position 22 is arranged at one end of the bottom surface of the hinge 2 close to the end connected with the hinge spring 3, and the door body 1 is opened to the maximum angle when the auxiliary arc position 22 is close to the roller 42. In the structure, the radian of the auxiliary arc screens is the same as the appearance radian of the roller, so that the auxiliary arc screens are adjacent to the roller, when the hinge slides to the auxiliary arc screens and the roller is adjacent, the door body is opened to the maximum angle, and the door body can be hovered.
Optionally, a self-closing door interlocking slope 23 is provided at the end of the bottom surface of the hinge 2 near the connection with the door hinge support 5, and the door 1 is in a closed state when the self-closing door interlocking slope 23 is close to the roller 42.
In the structure, the self-closing door interlocking inclined plane is inclined from one end connected with the hinge support of the door body to the lower part of the other end, so that the roller can block certain resistance generated in the front of the inclined plane after the door body is closed, the hinge spring can also generate certain door closing tension, the door body can be automatically locked when closed, and the condition that the door body is automatically opened can not occur.
As an optional implementation manner, the self-closing door interlocking inclined plane is an arc surface, when the self-closing door interlocking inclined plane is tangent to the arc surface of the roller, the door body is in a closed state, and the pulling force generated by the hinge spring can pull the door body to a door-closing state, that is, the door body realizes self-locking, so that the process of installing a lock catch on the door body is omitted, a user can open or close the door body more conveniently, and the application effect is better. Different self-locking capacities are required to be matched due to different weights of different door bodies, and different self-locking capacities can be realized by adjusting the tension of the hinge spring and the inclination angle of the self-closing door interlocking inclined plane or the radius of the arc surface, so that the self-locking structure can be applied to different door bodies.
Optionally, an inclined smooth plane 21 is formed between the self-closing door interlocking inclined plane 23 and the auxiliary arc position stop 22. The larger the opening angle of the door body is, the larger the door closing pulling force generated by the hinge spring is, so that the friction force between the hinge and the roller is larger and larger through the structure, and the requirement of hovering the door body can be met.
Optionally, the wire diameter and the number of turns of the hinge spring 3 are both adjustable. Because the door body structure molding of different products is different, therefore weight is also different, for example the door body installs the alloy handle additional, install multilayer insulating glass and glue additional, full package formula or half package formula door subassembly, increase stainless steel decorative board etc, the weight of these door bodies is all inequality, consequently, the specification of the hinge spring who uses when adopting the drop-down door structure of this embodiment also is different, match the hinge spring of corresponding specification according to actual door body weight, and hinge spring's change is convenient and fast more, this application scope that has just greatly enlarged this embodiment, practicality and commonality have been strengthened.
