Description
Technical field
Automatic field is the utility model is related to, particularly a kind of pulley mechanism of sliding door.
Background technology
Reference picture 4, the pulley mechanism of sliding window bottom being currently used for, the thickness of its bearing and glue coating wheel is small, in use, because
The weight weight of door, glue coating wheel are easily worn, and bearing is easily damaged, moreover, pulley mechanism is to adopt to be screwed in sliding door bottom
Portion, the area that it withstands forces is small, and rear wheel mechanism is used for multiple times and easily pitches, meanwhile, traditional pulley mechanism typically only has
One bumper anticollision, single bumper can not play dust-proof effect.
The content of the invention
In order to solve prior art problem, the utility model provides a kind of service life length, good dustproof effect, installation stabilization
Sliding door pulley mechanism.
To achieve the above object, technical scheme provided by the utility model is：A kind of pulley mechanism of sliding door, installation
In the bottom of sliding door, described pulley mechanism includes mounting bracket, and the mounting bracket middle part is hollow and is provided with by bearing
Glue coating wheel, it is characterised in that：The mounting bracket includes framework and underframe, by step between the upper framework and underframe
Transition, the width of the upper framework and the installing frame dimensional fits of sliding door, the width of the underframe are more than the peace of sliding door
The size that frames up simultaneously is stuck in outside the installing frame of sliding door, and it is described encapsulated for protecting that the glue coating wheel both ends are respectively equipped with a bumper
Wheel.
Preferably, the external diameter of the bearing is 35mm, and its thickness is 11mm.
Preferably, the bumper bottom has arcuate socket and coordinated with the track of sliding door bottom for dust-proof.
Preferably, the thickness of the glue coating wheel is 11.4mm.
Preferably, the width of the upper framework is 15mm, and the width of the underframe is 17.5mm.
The utility model has the advantages that：
The utility model increases the thickness of bearing and glue coating wheel, improves its service life, moreover, mounting bracket employs
The structure of upper framework and underframe, during installation, underframe has been stuck on the outside of the installing frame of sliding door, and the area that it withstands forces is big,
Installation is stable, too big pressure will not be produced to fixed screw, so that pulley mechanism is not easy to loosen, moreover, lower frame
The width of frame is set up to 17.5mm, bearing and glue coating wheel after so convenient installation thickening, employs two bumpers, not only
Anticollision can be played a part of, and dustproof and waterproof can be played a part of, avoiding dust from entering influences making for bearing in bearing
With the life-span, it can also prevent glue coating wheel from departing from track.
Brief description of the drawings
Fig. 1 is stereogram of the present utility model；
Fig. 2 is front view of the present utility model；
Fig. 3 is left view of the present utility model；
Fig. 4 is the left view of existing pulley mechanism；
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model will be further described：
Referring to figs. 1 to Fig. 3, a kind of pulley mechanism of sliding door, the bottom of sliding door, described pulley mechanism bag are installed on
Mounting bracket 1 is included, the middle part of mounting bracket 1 is hollow and is provided with glue coating wheel 3 by bearing 2, and the mounting bracket 1 includes upper ledge
Frame 11 and underframe 12, by the transition of step 13 between the upper framework 11 and underframe 12, the width of the upper framework 11 is with pushing away
The installing frame dimensional fits of sliding door, the width of the underframe 12 are more than the installing frame size of sliding door and are stuck in the peace of sliding door
Frame up outer, can so considerably increase between pulley mechanism and the installing frame of sliding door and accept area, avoid to for solid
The too large impact of the screw of fixed pulley mechanism, reduce and loosen, the both ends of glue coating wheel 3 are respectively equipped with a bumper 4 and are used to protect
The glue coating wheel 3, so can not only play more preferable collision prevention function, moreover it is possible to play dust-proof purpose.
Specifically, the external diameter of the bearing 2 is 35mm, its thickness is 11mm, and original bearing outside diameter is 26mm, thickness
It is 8mm, during original bearing use, the frequent situation that fails, after more preferable bearing newly, service life increases
Add.
Specifically, the bottom of bumper 4 has arcuate socket 41 and coordinated with the track of sliding door bottom for dust-proof, arc
Shape hole 41 just coordinates with section for the track of arc, water proof and dust proof, can prevent glue coating wheel from departing from track again.
Specifically, the thickness of the glue coating wheel 3 is 11.4mm, and original is 8mm, the thickness of the glue coating wheel 3 added.
Specifically, the width of the upper framework 11 is 15mm, the width of the underframe 12 is 17.5mm.
The utility model increases the thickness of bearing 2 and glue coating wheel 3, improves its service life, moreover, mounting bracket 1 is adopted
With the structure of upper framework 11 and underframe 12, during installation, underframe 12 has been stuck on the outside of the installing frame of sliding door, and it withstands forces
Area it is big, too big pressure will not be produced to fixed screw, so that pulley mechanism is not easy to loosen, moreover, lower frame
The width of frame 12 is set up to 17.5mm, bearing 2 and glue coating wheel 3 after so convenient installation thickening, employs two bumpers
4, it can not only play a part of anticollision, and dustproof and waterproof can be played a part of, avoiding dust from entering in bearing influences axle
The service life held, it can also prevent glue coating wheel from departing from track.
The utility model examples of implementation described above are only the preferred embodiment of the utility model, not limit this with this
The practical range of utility model, therefore the change that all shape, principles according to the utility model are made, all should cover in the utility model
Protection domain in.
