Abstract
The utility model provides a quick exchanging joint of drilling tool, comprising a socket hole. A slidable magnet and the sliding spacing thereof are arranged in the socket hole, and an elastic functional element is provided behind the magnet. The utility model with simple structure and convenient installation can guarantee the convenient and safe mounting and dismounting of the drilling tool. The elastic element can be a spring or a magnet which is isotropistic and faces to the above magnet, and a magnet barrier block is provided behind the elastic element of magnet.
Description
Technical field
The utility model relates to a kind of hydraulic quick coupler of drilling tool.
Background technology
Drilling tool, such as various carpenters, they are by its drillstock of drill chuck clamping, by electric drill driving carrying out work, when changing drilling tool, drilling tool need be pulled down from chuck and be refilled other drilling tools, very therefore trouble much is at present to adopt the method for hydraulic quick coupler switching that drilling tool is installed, i.e. the drillstock of drill chuck gripping quick-changing joint, be provided with in the hydraulic quick coupler and the drilling tool socket aperture that cooperates of end of plugging into, finish the disassemble and assemble work of drilling tool by hydraulic quick coupler fast.Present some hydraulic quick coupler, in order to further facilitate the dismantlement work of drilling tool, in socket aperture, be provided with power assistant spring, so that when pulling down drilling tool, drilling tool is released socket automatically, but this structure, its elastic force often is difficult to control well, make that speed, distance, the strength released are often excessive, be easy to cause security incidents such as drilling tool accidental injury.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of hydraulic quick coupler that overcomes the drilling tool of above defective.For this reason, the utility model by the following technical solutions: it comprises socket aperture, is provided with the spacing of magnet slidably and slip thereof in the socket aperture, and the rear of magnet is provided with the elastic reaction element.Because adopt above technical scheme, it is simple in structure, easy for installation, guarantee the convenience and the safety of drilling tool loading and unloading.
Described flexible member can be spring.
Or described flexible member is the magnet of facing with the aforementioned magnet same sex.The back of described flexible member magnet is provided with every magnetic patch.
Comparatively speaking, lower with spring, not only simple in structure and needn't resemble that the material to socket has certain requirement the magnet flexible member as the flexible member cost.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment 1.
Fig. 2 is the schematic diagram of the utility model embodiment 2.
The specific embodiment
Embodiment 1
With reference to accompanying drawing 1.It comprises socket aperture 1 the utility model, be provided with in the socket aperture magnet 3 slidably and slide spacing 4, the rear of magnet is provided with elastic reaction element 2.
Described flexible member can be spring.As shown in Figure 1, the inner end portion diameter of socket aperture becomes the chute 5 of magnet more greatly, and the outer end portion 6 of socket aperture is thinner, and inside and outside two parts joint becomes spacing 4 of magnet.The outer end portion 6 of socket aperture is polygon prism-shaped and transmits torsion.Drawing reference numeral 7 is the operating sleeve of hydraulic quick coupler.
After drilling tool inserted socket aperture, its shank was inhaled mutually with magnet, and spring is compressed simultaneously.When the dismounting drilling tool, pull operation cover, socket rely on the screen resilience of spring to the drilling tool release, and drilling tool is ejected, but because the restriction of spacing 4 pairs of magnet relies on magnetic force to inhale mutually even with magnet and drillstock, drillstock can only can not flown out to the aperture by the top and hurt sb.'s feelings.
Embodiment 2
With reference to accompanying drawing 2.Present embodiment comprises socket aperture 21, be provided with in the socket aperture magnet 23 slidably and slide spacing 26, the rear of magnet is provided with elastic reaction element 22.Flexible member is the magnet of facing with the aforementioned magnet same sex.The back of described flexible member magnet is provided with every magnetic patch 25.Drawing reference numeral 24 is a drillstock.Other is with embodiment 1.
Claims (4)
1, a kind of hydraulic quick coupler of drilling tool comprises socket aperture, it is characterized in that being provided with in the socket aperture the spacing of magnet slidably and slip thereof, and the rear of magnet is provided with the elastic reaction element.
2, the hydraulic quick coupler of a kind of drilling tool as claimed in claim 1 is characterized in that described flexible member is a spring.
3, the hydraulic quick coupler of a kind of drilling tool as claimed in claim 1 is characterized in that described flexible member is the magnet of facing with the aforementioned magnet same sex.
4, the hydraulic quick coupler of a kind of drilling tool as claimed in claim 3 is characterized in that the back of described flexible member magnet is provided with every magnetic patch.
