Abstract
The utility model discloses a wheel mounting device capable of automatically adjusting wheel distance, which is characterized by comprising a fixed plate and a rotary plate which are mutually vertical and a torsional spring arranged at the top surface of the rotary plate, wherein a mounting hole is formed in the middle of the rotary plate, and wheels are fixedly mounted at the two ends of the rotary plate; the two ends of the torsional spring are hooked, the axial through hole of the torsional spring is overlapped with the mounting hole of the rotary plate, and the two hooked ends of the torsional spring are hooked with the fixed plate and the rotary plate respectively; the torsional spring, the rotary plate and the fixed plate are in rivet connection. The wheel mounting device disclosed by the utility model has the benefits that the design is novel and the structure is reasonable; when the sliding door moves, the wheels can be satisfactorily contacted with the track all the time under the action of the torsional spring, so as to remove the gap between the wheels and the track, consequently, not only is the sliding door prevented from vibrating, but also the noise caused by the friction of the wheels and the track is effectively reduced, and then an excellent mute effect is achieved; furthermore, as the wheel distance is adjustable, the wheel mounting device can be mounted inside the track with much convenience.
Description
Technical field
The utility model relates to a kind of upper wheel apparatus, is specifically related to a kind of upper wheel apparatus of regulating wheel distance automatically, belongs to haberdashery and hardware manufacturing technology field.
Background technology
The existing upper wheel apparatus being installed on sliding door, itself and the man-to-man formulation that coordinates of getting on the right track, after long-term use, guide rail inwall can produce deformation to a certain degree, and because the wheelspan between two wheels of upper wheel apparatus is fixing non-adjustable, therefore wheel and guide rail inwall will produce certain gap, people are in use due to the inertia of sliding door and the effect in gap, especially when open and close door, sliding door not only can produce and rock, but also can produce friction noise, and affect the application life of product; In addition, in order to reduce the gap between wheel and guide rail inwall, that conventionally wheelspan can be designed is larger as far as possible, but because wheelspan is fixing non-adjustable, inconvenience is not only installed, and adjusting is very difficult.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of upper wheel apparatus that can effectively overcome because of the regulating wheel distance automatically that is applicable to sliding door of friction, collision and noise that gap produces.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
Automatically a upper wheel apparatus for regulating wheel distance, is characterized in that, comprising: have the fixed head of screw fixing hole, with the vertically disposed rotor plate of fixed head, the centre of such rotation plate is formed with installing hole, and the two ends of rotor plate are installed with wheel; Also comprise: be arranged on the torsion spring of rotor plate end face, the two ends of aforementioned torsion spring are formed with barb, the axially extending bore of torsion spring and the installing hole of rotor plate are overlapping, and the barb at two ends hooks respectively fixed head and rotor plate; Aforementioned torsion spring, rotor plate and fixed head are connected by rivet.
The upper wheel apparatus of aforesaid regulating wheel distance automatically, is characterized in that, the side of such rotation plate is formed with the first torsion spring screens for hooking torsion spring.
The upper wheel apparatus of aforesaid regulating wheel distance automatically, is characterized in that, the side of aforementioned fixed head is formed with the second torsion spring screens for hooking torsion spring.
The upper wheel apparatus of aforesaid regulating wheel distance automatically, is characterized in that, between aforementioned fixed head and rotor plate, is provided with packing ring.
The upper wheel apparatus of aforesaid regulating wheel distance automatically, is characterized in that, on aforementioned fixed head, guide pillar is installed, and aforementioned guide pillar vertically arranges.
Usefulness of the present utility model is: modern design, and rational in infrastructure; In the time that sliding door moves, due to the effect of torsion spring, wheel can keep good contacting the moment with track, gap between the two disappears, not only avoid sliding door to produce and rocked, and effectively reduced between wheel and track because of fricative noise, there is good muting function; In addition, because wheelspan is adjustable, greatly facilitate upper wheel apparatus is installed to the operation in track.
Brief description of the drawings
Fig. 1 is the STRUCTURE DECOMPOSITION figure of a specific embodiment of upper wheel apparatus of the present utility model;
Fig. 2 is the assembling schematic diagram of the upper wheel apparatus in Fig. 1.
The implication of Reference numeral in figure: 1-fixed head, 2-rotor plate, 3-torsion spring, 4-rivet, 5-guide pillar, 6-packing ring, 7-wheel, 8-pin, 9-the first torsion spring screens, 10-the second torsion spring screens.
Detailed description of the invention
It should be noted that, in this case, wheelspan refers in the direction vertical with track length direction, the vertical distance between two wheels, but not the length of the line of centres of two wheels.
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
See figures.1.and.2, upper wheel apparatus of the present utility model comprises: fixed head 1, rotor plate 2, wheel 7 and torsion spring 3, wherein, be formed with screw fixing hole, for whole device is fixed to header on fixed head 1; Rotor plate 2 setting vertical with fixed head 1, and can rotate with respect to fixed head 1, the centre of rotor plate 2 is formed with installing hole, and the two ends of rotor plate 2 are installed with wheel 7 by means of pin 8; Torsion spring 3 is arranged on the end face of rotor plate 2, and the two ends of torsion spring 3 are formed with barb, is respectively used to hook fixed head 1 and rotor plate 2.When installation, need to be by overlapping the installing hole of the axially extending bore of torsion spring 3 and rotor plate 2, then by means of rivet 4, from top to bottom successively through torsion spring 3, rotor plate 2 and fixed head 1, thereby three is connected together, now need to ensure that rotor plate 2 still can rotate with respect to fixed head 1.
In the time that sliding door moves, due to the effect of torsion spring 3, wheel 7 can keep good contacting the moment with track, gap between the two disappears, not only avoid sliding door to produce and rocked, and effectively reduced between wheel 7 and track because of fricative noise, there is good muting function; In addition, because wheelspan is adjustable, greatly facilitate upper wheel apparatus is installed to the operation in track.
As the preferred scheme of one, the side of rotor plate 2 is formed with the first torsion spring screens 9, and it is for hooking a barb of torsion spring 3.
More preferably, the side of fixed head 1 is formed with the second torsion spring screens 10, and it is for hooking another barb of torsion spring 3.
In order to reduce the very stiff and demanding friction between fixed head 1 and rotor plate 2, between fixed head 1 and rotor plate 2, be provided with packing ring 6, can play good cushioning effect.
As the preferred scheme of one, guide pillar 5 is installed on fixed head 1, guide pillar 5 vertically arranges, and coordinates with the guide pillar groove on guide rail, can effectively reduce the wearing and tearing between guiding cheekn and upper wheel apparatus.
