Abstract
The utility model relates to a top removal structure comprising a base, a top removal structure and a top removal screw, wherein the base is provided with a threaded through hole and the top removal screw; and the position on the top removal structure positioned at the threaded through hole of the base is provided with a top removal column which has the diameter larger than that of the threaded hole. The top removal device adopts the large-strength top removal column structure, can guarantee no abrasion and no damage at the top removal position of a casing whether the mounting and dismounting are frequent or not; the top removal device has simple structure, and is easy to process; a top removal mounting hole can be additionally processed after the casing is processed, and simultaneously the mounting effect is obvious; and the top removal device can be widely used in various detachable mechanisms.
Description
Technical field
The utility model relates to a kind of ejection device.
Background technology
In the existing mechanical structure, playing ejection device generally is screwed hole of side processing of the installation limit faying face between the parts that two needs decompose, the similar bolt of top lifting instrument, the screw-in by screw thread with two parts separately, thereby reach the purpose of dismounting.But long-time repeatedly dismounting certainly will cause the wearing and tearing of roof construction, may cause that at last parts install limit intensity inefficacy, fault such as cracks.
Summary of the invention
The purpose of this utility model provides a kind of good reliability, can not wear and tear by housing, guarantees to install a kind of anti-wear ejection device of limit intensity.
Concrete technical scheme of the present utility model is: device comprises that pedestal, a roof construction have reached screw, described pedestal is provided with tapped through hole and screw has been installed, play the upper position of roof construction and be provided with fore-set in the base thread through hole, the diameter of described fore-set is bigger than screwed hole, and it is big that intensity plays roof construction.Described fore-set has been installed on the roof construction by interference fit.
The utlity model has tangible beneficial effect, the top lifting rod structure of big intensity adopt to be installed, whether frequently no matter dismantle, can both guarantee that housing top lifting position is not frayed, guarantee intact.The utility model is simple in structure, and handling ease can machine in addition processing top lifting installing hole of back at housing, and it is obvious that effect is installed simultaneously, can be widely used in various dismountable mechanisms.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
The specific embodiment
As shown in the figure, device comprises that pedestal 1, a roof construction 2 have reached screw 3, described pedestal 1 is provided with tapped through hole and screw 3 has been installed, play the position that is positioned at pedestal 1 tapped through hole on the roof construction 2 and be provided with fore-set 4, the diameter of described fore-set 4 is bigger than screwed hole, and it is big that intensity plays roof construction (2).Described fore-set 4 has been installed on the roof construction by interference fit.
Claims (3)
1. one kind is played ejection device, it is characterized in that, device comprises that pedestal (1), a roof construction (2) have reached screw (3), described pedestal (1) is provided with tapped through hole and screw (3) has been installed, play the position that is positioned at the base thread through hole on the roof construction (2) and be provided with fore-set (4), the diameter of described fore-set (4) is bigger than tapped through hole.
