Description

Sliding hanger for shifting a hinge point}

The present invention relates to a sliding hanger for the nodal movement of an X type lift for an electric bed, and the X-lift device is provided with a function to freely induce the up and down operation of the up and down horizontal lifting or tilting angle or the inclination angle of one end. It is characterized by the provision of.

In general, the X-type lift is configured such that the node is fixed to the center intersection of the left and right X bars so that only the horizontal movement is possible when the lift is lowered.

The X-type lift is used for the maintenance of automobiles, and is a device that moves heavy objects from a low place to a high place, and can be divided into four shares or a buried type, and is commonly used to raise and lower horizontally. Because the payload of the lift is a natural binding state due to the self-weight inertia, there is also an advantage of not having an additional binding device, but there is a disadvantage that it can only move horizontally.

The present invention is the X-type which operates only the horizontal movement of the X-bar rod and the X-bar rod movement guide by the operation of the oil / pneumatic cylinder or the motor and the screw bar of the drive unit which drives the lifting and lowering operation of the X-type lift. By implementing the required inclination angle during the lifting and lowering operation of the X lift by inducing the free movement of the center of the node by the sliding device for the hanger 110, which is the device of the present invention, the X-bar center-center node (Fig. 2 100) of the lift, The X-lift of the electric bed or the mechanism of the working machine is designed to be simple and reduce the manufacturing cost.

.

As shown in Figures 1 and 2, the conventional X-type lift is a node (100 in Figure 1) of the X bar 40 is fixed to the center of the X bar 40 to implement the inclination angle by the independent elevating operation Could not.

3 to 4 by using the nodal sliding sliding hanger device 110 of the present invention shown in Figures 3 to 4 in the center of the X-bar 40 without setting the node 100, the novel device sliding hanger By moving the node (200 in Fig. 4) to the device 110, the pair of X bars play the role of an individual stand-alone type X bar 40 rod only, and it is possible to operate the scissors in separate operations.

As shown in FIGS. 3 and 4, the fixed node (100 in FIG. 1) of the X bar is replaced by (200 in FIG. 4), and individual ball bearings 120 are disposed at regular intervals inside the 1 rod and 2 rods of the reference numeral 110. The friction member which internally minimizes the friction load with the X-bar 40 rod was applied.

The operation of the X lift to which the subject is applied is as follows. The left and right sides of the X lift are connected to the motor, screw, or hydraulic and pneumatic cylinders to operate the X bars of the two pairs simultaneously by forward or reverse rotation. The city moves up and down the inclined angle by moving up and down horizontally and pushing or pulling only one side. Here, the scissors motion of the X bar 40 of FIG. 1 is that the forward motion is developed by the center motion of the center node of reference numeral 100, that is, the X bar without the center node is freely operated by the driving force.

As shown in FIG. 5, when the motor 50 or the hydraulic / pneumatic cylinder is connected to the lower left and right ends of the X bar and pulls one end, the node 110 moves the one end of the X bar 40. As it moves to, the bar on one side of the X bar makes an upward inclination angle.

The design is completed because the separation caused by the node movement 200 of the X lift X bar 40 is induced to implement the horizontal or inclined angle freely by the node moving device 110.

FIG. 6 is a schematic view illustrating a rectangular structure according to the structure of the X bar 40 of the X lift as another embodiment of the present invention. The X bar 40 inside the 1.2 rod of the node-moving sliding hanger 110 is illustrated in FIG. An embodiment in which the roll bearing 120 is adopted to reduce the frictional load of the fuel cell may be adopted.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by those of ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Such changes will fall within the scope of the claims.

The above-described present invention is horizontal that the X lift was performing only the horizontal-oriented lifting operation. In addition, the operation of the inclination angle maintenance state also induces the inclination angle stably by the movement of the node, so that the operating force can be improved, and the reduction of the driving member can lead to various effects such as reducing the production cost of demand equipment and contributing to the convenience of users. It is a getaway that can be obtained.
