Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail:
Referring to accompanying drawing 1 to shown in accompanying drawing 2, door and window track pulley assembly described in the present embodiment, it includes shell 1, inner casing 2 and hitch frame 5, wherein, the relative two sides of inner casing 2 are equipped with pulley installing hole 203, pulley pin shaft 301 is through pulley 3 and coordinate assembling with pulley installing hole 203, pulley 3 is flexibly connected on inner casing 2, the relative two sides of this inner casing 2 are equipped with oblique slotted hole 201, the relative two sides of shell 1 are provided with A circular hole 101, on the two sides of inner casing 2 one end, be provided with the A circular hole 202 taking oblique slotted hole 201 centers as round dot, described hitch frame 5 one end openings, one end sealing, the two sides of these hitch frame 5 openends are provided with the B circular hole 501 corresponding with A circular hole, hitch frame 5 inserts the opening of inner casing 2, and flange pin 6 is through A circular hole 202 and B circular hole 501, inner casing 2 and hitch frame 5 are flexibly connected, described flange pin 6 is divided into three grades, and coaxial, middle one-level is larger than relative flange pin 6 two ends, this makes flange pin 6 have the function of pre-slip-off preventing, match with A circular hole 202 and B circular hole 501 in the two ends of flange pin 6, the centre position of described hitch frame 5 two sides is provided with lateral adjustments hole 502, the two sides of the blind end of hitch frame 5 are provided with square nut square hole 503, the relative two sides of shell 1 are provided with B circular hole 102, nut 8 is placed on nut square hole 503 and is blocked, now, the inner casing having connected 2 and hitch frame 5 are put in shell 1, and with A pin 4 through A circular hole 101 and oblique slotted hole 201, with B pin 7 through B circular hole 102 and lateral adjustments hole 502, shell 1 and hitch frame 5 are flexibly connected, on the end face of described hitch frame 5 blind ends, be provided with bolt and cross a hole 504, one end face of shell 1 is provided with bolt mounting holes 103, bolt 9 is through bolt mounting holes 103, bolt is crossed a hole 504 and is assembled with nut 8, the thread root of described bolt 9 has screens groove 901, by on the screens groove 901 of baffle plate 10 inserting bolts 9, now, this door and window track pulley assembly completes assembling.
Due to the shell 1 of this door and window track pulley assembly, inner casing 2 and hitch frame 5 are flexible connection, when door and window track is installed not at ordinary times, inner casing 2 can be done around A pin 4 swing of seesaw type, this just can make pulley 3 can comply with physical features automatically to adjust, ensure that pulley 3 contacts with door and window track all the time, the situation of effectively having avoided single-wheel contact or pulley 3 to derail, and the A circular hole 202 of inner casing 2 and the B circular hole of hitch frame 5 501 are by flange pin 6 Matching installations, in the time that inner casing 2 is done seesaw type swing, flange pin 6 can be freely movable along A circular hole 202 and B circular hole 501, to assist the pendulum angle of inner casing 2, and in the time of load, be stationary state, simultaneously, owing to being provided with hitch frame 5, turn bolt 9, the nut 8 that is fixed on nut square hole 503 is made screw motion with bolt 9, and the two sides of hitch frame 5 are equipped with lateral adjustments hole 502, now, hitch frame 5 can move horizontally along shell 1, this hitch frame 5 can promote again inner casing 2, A pin 4 is relatively moved along oblique slotted hole 201, this makes inner casing 2 can carry out height fine setting, strengthen the adaptive capacity of this pulley assembly, and in the time inner casing 2 being adjusted to ultimate limit state with bolt 9, be that inner casing 2 is while being adjusted to the highest or minimum state, by being provided with A circular hole 202 and B circular hole 501, make at inner casing 2 during at the highest or minimum state, inner casing 2 still can reach the effect that seesaw swings, effectively improve existing track pulley assembly amplitude of fluctuation little, when limiting altitude, can only put on one side, regulate inflexible problem, the utility model is simple in structure, be easy to assembling, can effectively add bigger device has the pendulum angle of the inner casing 2 of pulley 3, and the flexibility ratio that inner casing 2 swings also improves greatly, in the time that being adjusted to ultimate limit state, inner casing 2 still can keep normal swing, this track pulley assembly flexible adjustment, accommodative ability of environment is strong.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit practical range of the present utility model with this, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
