Abstract

The utility model discloses a handle pulling mechanism of a scalable supporting table, comprising a handle, 3 pairs of pins, an upright and a scalable supporting table. The supporting table is supported by a slideway at two sides of the upright. Two arms of the handle are provided with long holes. The bottom of the handle is provided with a stopping boss. The side of the slideway of the upright is provided with a long hole. A removing pin is fixed at two sides of the scalable supporting table and extends out from the long hole of the slideway on the upright. A fulcrum pin and a limit pin are respectively fixed on the upper and the lower part of the slideway of the upright. Two arms of the handle are sheathed on the fulcrum pin and the removing pin. When on working position, interaction of the stopping boss on the bottom of the handle and the limit pin together acts and restricts the return travel of the handle and assures the reliability of the supporting table. When the handle is lifted and then pushed, the handle drives the removing pin to drive the supporting table to move; the handle is loosened when the supporting table is back, the stopping boss of the handle drops into the other side of the limit pin, then the conversion from working position to non working position of the supporting table can be realized. Reverse operation of the process is a process of conversion from non working position to working position of the supporting platform. The handle pulling mechanism is simple and flexible in operation, is not restricted by operation space and is safe and reliable.

Description

The handle pulling mechanism of retractable supports platform

Technical field

The utility model relates to the pulling mechanism in the telescopic supporter of using in a kind of field of engineering technology.

Background technology

The brace table that arrives commonly used as a reversible platform, need need be packed up brace table when it is not worked with it to brace table when its work in engineering, turns down platform.Because brace table below platform, directly manually is subjected to the considerable restraint of operating space.

The utility model content

In view of above-mentioned; the purpose of this utility model provides reliable, the simple in structure effective pulling of a kind of flexible operation mechanism; directly manually flexible brace table is converted to handle pulling mechanism, and promptly human-saving is not subjected to the influence of operating space again, has the backhaul protective effect simultaneously.

For this reason, the utility model is by the following technical solutions:

A kind of handle pulling mechanism of retractable supports platform comprises pillar and extension type brace table, and telescopic brace table be is characterized in that by the slideway supporting that is located at the pillar both sides:

It also comprises handle, 1 pair of fulcrum pin, 1 pair of finger and 1 pair of spacer pin, wherein:

Described handle takes the shape of the letter U, and its two arms connecting portion is a handle, has axisymmetric slotted hole on two arms along its length, and the bottom of two arms is provided with stop ledge;

The side of the slideway of described pillar both sides laterally has slotted hole;

Described 1 pair of finger is fixed on the both sides of extension type brace table, and stretches out from the slotted hole of described pillar sliding way;

Described fulcrum pin and spacer pin are separately fixed at the slideway above and below of pillar both sides;

Two arms of described handle are enclosed within on described fulcrum pin and the finger by the slotted hole on its arm.

Described fulcrum pin, finger and spacer pin are straight pin.

Described pin part is the straight pin of 6 symmetric arrangement, and wherein two pins are fixed on the extension type brace table to drive its motion.All the other have sold turning cylinder and spacing effect.

When the utility model was in the operating position, the drawback movement that the stop ledge of handle bottom and spacer pin acting in conjunction have limited handle guaranteed the reliability of extension type brace table when working position.

The utility model will be by working position when change the inoperative position, light handle makes progress, driving handle, handle drives finger and drives the brace table motion then, after the brace table income, release handle, handle falls under the gravity effect automatically, stop ledge falls into the spacer pin opposite side, finishes brace table thus by the conversion of working position to the inoperative position.This process of contrary operation is that brace table is by the process of inoperative position to the working position conversion.

The utility model has the advantages that:

1, flexible operation is simple;

2, not limited by the operating space;

3, safe and reliable.

Description of drawings

Fig. 1, Fig. 2 are respectively schematic front view, the left view of the utility model structure when working position;

Fig. 3～Fig. 5 is the utility model structure operation step schematic diagram.

The specific embodiment

Be described further below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, the utility model is a kind of handle pulling mechanism of retractable supports platform, comprises that 1,3 pairs of pins 2 of handle, extension type brace table 4 and pillar 5,3 are overturn platform.Wherein:

Telescopic brace table 4 is by the slideway supporting that is located at pillar 5 both sides, and the side of the slideway of pillar 5 both sides laterally has slotted hole.

Handle 1 takes the shape of the letter U, and its two arms connecting portion is a handle, has axisymmetric slotted hole on two arms along its length, and the bottom of two arms is provided with stop ledge.

3 pairs of pins 2 are straight pin, are divided into 1 pair of fulcrum pin, 1 pair of finger and 1 pair of spacer pin.Wherein, 1 pair of finger solid welding is in the both sides of extension type brace table 4, and stretches out from the slotted hole of the slideway of pillar 5; Fulcrum pin and the solid welding of spacer pin difference are in the slideway above and below of pillar 5 both sides.Finger is in order to drive the motion of extension type brace table, and fulcrum pin and spacer pin play turning cylinder and spacing respectively.

Two arms of handle 1 are enclosed within on fulcrum pin and the finger by the slotted hole on its arm.

After being separately fixed at 3 pairs of straight pins of this practicality on flexible brace table and the column, two arms of handle 1 are enclosed within back (showing as Fig. 2) on the pin, again with handgrip and handle solid welding, just finish assembling.

Introduce the operating procedure of the utility model structure below in conjunction with Fig. 3～Fig. 5:

When the utility model is in the operating position (shown in Figure 2), the return-stroke type motion that has limited handle because of the stop ledge and the below spacer pin acting in conjunction of handle bottom is so make brace table be in the operating position reliably.

When the flexible brace table withdrawal of needs promptly was converted to the inoperative position, the light handle that makes progress earlier made the restriction (showing as Fig. 3) of the stop ledge disengaging below spacer pin of handle, driving handle then, make handle make drawback movement, the slotted hole of handle drives finger to swivel motion, and finger drives brace table again to swivel motion, realize brace table retraction (showing) as Fig. 4, behind the return, release handle is under the gravity effect, handle falls, and so far finishes whole process.

This process contrary operation is that brace table stretches out the process that promptly is converted to working position.
