Technical Field

The invention relates to the technical field of sliding doors, in particular to a double-pulley-block structure.

Background

With the continuous development of modern life, the functions of the kitchen are continuously increased, the original simple functions of washing vegetables and cooking are developed to the extent that various electric appliances (large-scale refrigerators, electric ovens and dish washers) enter the kitchen, and the selection of the sliding door is diversified and developed.

The double-pulley block and double-rail section bar are installed on most sliding doors in the market, the double pulleys are inserted into one end of the double-rail section bar, the double-rail section bar is installed in advance before a wall door opening is decorated, the double-pulley block is inserted into the double-pulley block, in this way, once the pulleys have problems, the decorated wall door opening part needs to be dismantled, the double-rail section bar is dismantled, the double-pulley block is repaired or replaced, and then decoration is supplemented, so that secondary decoration cost on engineering can be formed, even if the double-rail section bar is not dismantled, a ceiling is arranged on a roof in advance, and a maintenance hole is reserved in the ceiling so as to replace the pulleys, the maintenance is inconvenient, and due to the fact that the ceiling is arranged, the height in a room is reduced, and therefore a double-pulley block structure is provided for later maintenance.

Disclosure of Invention

The invention aims to solve the problems that in the prior art, pulleys of a sliding door are inconvenient to disassemble and high in later maintenance cost, and provides a double-pulley-block structure.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a double pulley block structure, includes the leading wheel, the top of leading wheel is equipped with the entablature, be equipped with same door leaf between entablature and the leading wheel, the top side of door leaf extends to in the entablature, the bottom side fixed mounting of door leaf has material under the door, material under the door and leading wheel looks adaptation, the top of material under the door is equipped with the door side material that is located on the door leaf, the top of door side material is equipped with the door upper material of fixed mounting on the door leaf top side, the door upper material is located the entablature, fixed mounting has same glass on door upper material, door side material and the material under the door.

Preferably, the top side of the door upper material is provided with a rotating groove, a rotating nut is rotatably installed in the rotating groove, a nut post is installed on the inner thread of the rotating nut, a fixing nut is sleeved on the nut post in a threaded manner and located above the rotating nut, the fixing nut is rotated to enable the fixing nut to rotate on the nut post, the fixing nut is slowly separated from the rotating nut, and then the rotating nut is rotated to enable the rotating nut to rotate in the rotating groove in the door upper material.

Preferably, a wheel carrier fixedly sleeved on the nut column is arranged in the upper beam, a rotating hole is formed in the top side of the wheel carrier, the bottom end of the nut column penetrates through the rotating hole, the pulley is limited by the rail, the pulley, the wheel shaft, the connecting column, the wheel carrier and the nut column cannot rotate at the moment, and the nut column moves upwards due to the rotation of the rotating nut.

Preferably, the two sides of the wheel carrier are fixedly provided with connecting columns, the ends, far away from each other, of the two connecting columns are fixedly provided with wheel shafts, the two wheel shafts are rotatably provided with pulleys, and the nut columns move to drive the pulleys, the wheel shafts, the connecting columns and the wheel carrier to move upwards.

Preferably, all fixed mounting has the track on the both sides inner wall of upper beam, and two pulleys are located two tracks respectively, and when pulley and track phase separation, the pulley can rotate this moment, continues to rotate swivel nut and drives pulley, shaft, even post, wheel carrier and nut post and rotate, and the pulley rotates and shifts out the track, can take off the door leaf at this moment and change the pulley.

In the invention, as the fixing nut is arranged, the position of the rotating nut can be fixed through the fixing nut, and further the position of the pulley is fixed;

in the invention, the rotating nut is arranged, and the pulley is rotated by rotating the nut, so that the wheel is convenient to install;

according to the invention, when the pulley needs to be replaced, the double-rail section bar does not need to be detached, the fixing nut is rotated to separate the fixing nut from the rotating nut, the rotating nut is rotated to drive the pulley to move out of the track, the door leaf can be taken down, the pulley block is conveniently replaced or maintained, a ceiling is not needed, a maintenance hole is not needed, and the use requirements of people are met.
