Door dug hand, case dress mouth is directly outputed at the edge of sliding door is used for assembly door dug hand, and a secondary dug hand can undertake two sides push-and-pull
Function, but this door dug hand still suffers from weak point due to structure limitation in terms of stress reliability, shape-designing.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of modern design, reliability and durability concealed door dug hand.
In order to solve the above-mentioned technical problem, a kind of concealed door dug hand of the present utility model, this dug hand is stainless by five pieces
Steel is welded to form, and first, second, third steel disc separately constitutes top, rear lateral portion and the bottom of three-sides-square shape frame, the 4th steel disc point
It is not connected the centre position for being placed in three-sides-square shape frame in T-shaped with first, second, third steel disc, the 4th steel disc separates three-sides-square shape frame
Into left and right dug hand space；The leading edge bottom of 4th steel disc opens up breach, and the gap position is welded with the 5th steel disc, the 5th steel
Piece lower edge and the 3rd steel disc leading edge are welded；First steel disc, the leading edge of the 4th steel disc, the leading flank of the 5th steel disc are located at same
On one vertical plane；The top margin of 4th steel disc and base are equipped with the tenon of at least one protrusion, and the 4th steel disc back is provided with backwards
Raised trapezoidal inserted sheet, the first, the 3rd steel disc is offering tongue-and-groove respectively at tenon position above and below correspondence, the 4th steel disc is upper and lower
Tenon is inserted in the first, the 3rd steel disc tongue-and-groove and is welded and fixed respectively；Vertical slot is offered in the middle of second steel disc, it is described trapezoidal slotting
Piece passes through vertical slot, and vertical slot upper/lower terminal is welded and fixed with the 4th steel disc；Described first, second, third, the 5th steel disc
Width is identical.
Further improvement of the utility model, the two sides of the trapezoidal inserted sheet are striated rough surface.
Top surface, the 3rd steel disc bottom surface are that striated is thick on further improvement of the utility model, first steel disc
Rough surface.
The beneficial effects of the utility model are：The design using the 4th steel disc by three-sides-square shape frame be separated into left and right dug hand space,
The 5th steel disc by the use of bottom is as stress push-and-pull position, and user, which closes the door, both while catching on the right and left can move greatly initial stage
Make push-and-pull, one side of dug hand can also be used only；Because the 4th steel disc and first and third steel disc are on the basis of tenon tongue-and-groove grafting
On welded again, welding position is located at the back side, and this product moulding is unique, the attractive in appearance of dug hand has both been maintained, while also greatly reinforcing
The force structure of product；In addition, the design is also provided with the trapezoidal inserted sheet towards rear projection in the 4th steel disc back, a digging is improved
Hand bonds lifting surface area when installing with door, and bonding is more firm when making to install between dug hand and door.
