Abstract
The utility model relates to a slide rail device of a side-hung door opener. The purpose of the utility model is to provide a slide rail device, which is simple in structural design, convenient to assemble, and safe and smooth in sliding, of a side-hung door opener. The slide rail device comprises a fixed plate which is fixed on a door sheet and a door machine plate located in front of the fixed plate and used for loading a door machine; slide rails are arranged at the two sides of the fixed plate, respectively; more than two pulley blocks are arranged on the back or at the two sides of the door machine plate from top to bottom; each pulley block is composed of two pulleys which are arranged symmetrically about the central axis of the door machine plate, and the two pulleys of the pulley block are matched with the slide rails at the two sides of the fixed plate and slide on the two slide rails, respectively.
Description
Technical field
The utility model relates to a kind of horizontal opening door machine railroad.
Background technology
Existing travelling wheel type horizontal opening door machine, because it lands work, so there is the problem of surface relief, therefore a door machine need to have apparatus for automatically lifting to adapt to the fluctuating on ground.
As shown in Figure 1, current travelling wheel type horizontal opening door machine, is generally contained in door lifter base realizing the needed slide rail of automatic lifting (generally adopting two parallel straight pins and the form of sheathed Compress Spring outside pin).This way has several problems:
1, the length of slide rail is subject to the restriction of door lifter base frame, its limited length, and the running space of the slide block coordinating with slide rail is received considerable restraint, causes the amplitude of door lifter lifting limited;
2, for slide rail (straight pin) is integrated into door lifter, cause door lifter linkage editor complicated;
3, all more difficult control of the glacing flatness of the parallelism of two straight pins, straight pin itself, probably impact door machine slide block is along the slip of straight pin, serious situation may cause sliding (not dead), can cause door lifter that door body is upwards even toppled on top, cause the damage of door lifter and door.
Summary of the invention
The purpose of this utility model is to provide the horizontal opening door machine railroad that a kind of structure design is simple, easy to assembly, slip safety is smooth-going.
The purpose of this utility model is achieved through the following technical solutions: a kind of horizontal opening door machine railroad, and it comprises for being fixed on fixed head on door-plate and being positioned at before fixed head and for loading the door machine plate of a machine; Described fixed head both sides are respectively arranged with slide rail, the back side or the both sides of described door machine plate are provided with assembly pulley more than two from top to down, assembly pulley is two pulleys that are symmetrically set about door machine plate axis, two pulleys of described assembly pulley respectively with the slip that cooperatively interacts of the slide rail of fixed head both sides.
It also comprises that two parallel are arranged on the extension spring between a machine plate and fixed head, and the top of described extension spring is fixedly connected on a top for machine plate, and the bottom of extension spring is fixedly connected on the bottom of fixed head.
During use, fixed head is fixed on door-plate, be fixed on when allowing a machine contact with ground the extension spring that guarantees to be connected between a machine plate and fixed head in part extended state, extension spring can increase an earth-grasping force for machine upper roller in conjunction with the weight of door machine self by its pulling force like this.And side by side, fixed head there will not be not dead phenomenon with door machine plate in two extension springs.
Compared to prior art, the utility model has the advantage of:
1, door machine plate coordinates realization to slide with section bar slide rail by assembly pulley, and principle of confounding is simple, reasonable, more smooth and easy; Also convenient during installation.
2,, owing to having adopted than the existing scheme slide unit of standard (as pulley, pulley movement bearing and section bar slide rail) more, be not easy to occur that existing mechanism causes the phenomenon of can not slide (not dead) that the reason such as not straight causes because sliding part distortion, surperficial scratch, the size Control of slide rail own are not good; In addition due to adopted extension spring (replacement stage clip) realize between a machine plate and fixed head (slide rail) and slip restoring force, also reduced in the situation that ground drop is larger, the excessive situation of slip resistance being caused by excessive compression because of stage clip occurs.
3, fixed head (slide rail) can adopt section bar to make.Because section bar adopts mould, produce in batches, so the control ratio of its form factor is easier to reach comparatively desirable level, cost of production is also lower.And the slide rail of existing scheme (as straight pin etc.), the allowance control level of the production technology that it adopts can be more undesirable, can obviously affect result of use.
4, fixed head (slide rail) is a straight plate, and its length easily changes as required, sliding stroke compare before technology longer.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing horizontal opening door machine railroad.
Fig. 2 is the structural representation of a kind of embodiment of the utility model.
Label declaration: 1 fixed head, 2 machine plates, 3 slide rails, 4 pulleys, 5 extension springs.
The specific embodiment
Below in conjunction with Figure of description and embodiment, the utility model content is elaborated:
Be illustrated in figure 2 the embodiment schematic diagram of a kind of horizontal opening door machine railroad that the utility model provides, it comprises for being fixed on the fixed head 1 on door-plate and being positioned at fixed head 1 above and for loading the door machine plate 2 of a machine; Described fixed head 1 both sides are respectively arranged with slide rail 3, the back side or the both sides of described door machine plate 2 are provided with assembly pulley more than two from top to down, assembly pulley is two pulleys 4 that are symmetrically set about door machine plate 2 axis, two pulleys 4 of described assembly pulley respectively with the slip that cooperatively interacts of the slide rail 3 of fixed head 1 both sides.
Described horizontal opening door machine slide rail also comprises that two parallel are arranged on the extension spring 5 between a machine plate 2 and fixed head 1, and the top of described extension spring 5 is fixedly connected on a top for machine plate 2, and the bottom of extension spring 5 is fixedly connected on the bottom of fixed head 1.
Certainly, excessive in order to prevent that fixed head 1 and door machine plate 2 from can slide mutually, a limit point can be set at the both ends of fixed head 1.Also have, fixed head 1 of the present utility model can be according to design its length with needs, also can increase by the combination between polylith fixed head 1 stroke of package unit, for example, the quantity of fixed head 1 is arranged to two, between two fixed heads 1, also by example assembly pulley described above and slide rail 3, realizes its mutual slip.
