CN87213809U - Vacuum adsorber - Google Patents

Abstract

The utility model belongs to a manual tool for removing, which can be used in working environment where workpieces with hard and smooth surface need to be lifted or moved, and is particularly suitable in the industries of construction, decoration or glass products. The utility model is characterized in utilizing the vacuum principle of interior and exterior pressure difference and the eccentric locking mechanism of cam to make the tool of the utility model sorb firmly on hard and smooth surfaces, which provides a convenient place for operating staffs to give out strength. For relatively larger and heavier workpiece, more than two tools can be combined to reinforce the sorption strength of the tool. The utility model has the advantages of simple structure, light weight, easy fabrication, low cost, convenient and reliable operation as well as wide application range.

Description

Vacuum adsorber

The utility model belongs to a kind of hand with moving instrument, can be used for the workplace that all need extract or move the workpiece with hard smooth flat, is specially adapted to the industry of architectural decoration or glass product.

Need extract or move the workplace of workpiece at all,,, can imagine that this is an inconvenience how if not by instrument as door that big glass is installed, window, sales counter, automobile etc. with hard smooth flat.No matter be workpiece with hard smooth flat, or smooth hard plate, as glass plate, plastic board etc., smooth plane and heavy weight will cause breakage when moving easily because of neither one is firmly local.For this reason, the utility model provides a kind of not only easy to operate but also can alleviate labour's special tool.It uses up, inhales on flat board, just likes a handrail, and operating personal can be held in above it the workpiece extraction is assemblied in any up and down direction.

Design concept of the present utility model is a vacuum principle of utilizing the external and internal pressure difference, by cam Camlock mechanism, make between instrument and the workpiece that to produce external and internal pressure poor, this instrument is adsorbed on the smooth plane of hard securely, for operating personal provides a place that convenience is exerted oneself, after reaching the purpose of moving or assembling, as long as move hand lever, this instrument adsorption affinity that can disappear is withdrawn the workpiece that is adsorbed.If big heavier workpiece can be carried out the single-piece combination of this instrument more than two, to strengthen the reliability of this instrument.

Shown in Figure 1 is the single-piece structural representation of this utility model.

Shown in Figure 2 is the structural representation of this utility model single-piece when in running order.

The 1st, garden shape rubber plate, covering the half garden spherical bearing frame 2 that metal is made on the shape rubber plate of garden, one square shaft 3 is arranged on the central axis, the square shaft upper end connects an eccentric cam shaft 4, the square shaft bottom is connected with rubber plate, overlapping a spring 5 on the square shaft, the spring upper end withstands on the inboard of bearing support, the spring lower end is fixed on the pad 6, and spring plays a part to restore rubber plate, and a cam hand lever 7 is arranged on the eccentric cam shaft, when depressing the cam hand lever, eccentric cam shaft drives square shaft and extracts Xiang Jiao Ban And locking, makes to form evacuated space between workpiece and rubber plate, is adsorbed on the workpiece securely thereby reach this instrument.Finish using, the hand lever plate returns original position, leans on the tension force of spring that rubber plate is restored, and vacuum promptly disappears, instrument just can be withdrawn workpiece, for big heavier workpiece, plural one-piece unit can be assembled together, make a lever between the connection, both increased adsorption affinity, again handled easily.

The utlity model has the structure dexterity, light, easy to manufacture, cost is low, convenient and reliable operation, the advantage such as applied widely.

Claims (1)

1. A kind of manual tool that is used to extract or move workpiece with hard smooth flat, it is characterized in that covering on the garden shape rubber plate the half garden spherical bearing frame that metal is made, one square shaft is arranged on the bearing support central axis, the square shaft upper end connects an eccentric cam shaft, and a cam hand lever is arranged on the eccentric cam shaft, and the square shaft bottom is connected with rubber plate, one pad is arranged between the connection, overlapping a spring on the square shaft, the spring bottom is fixed on the pad, and the spring upper end withstands on the inboard of bearing support.
