Description
Technical field
The utility model relates to a kind of large-scale rack installation auxiliary device, particularly a kind of drawing-aid device.
Background technology
Large-scale rack is many software companys, Communications service company is extensive use of, in the installation process of rack, there is a large amount of single-decks to need to insert in the rack successively in order, and these single-decks also need frequent replacing in process used in everyday, because the operating space was little when these single-decks damaged easily and install, installs and change very inconvenience.
The utility model content
The purpose of this utility model is to provide a kind of drawing-aid device, uses this drawing-aid device plug single-deck not only convenient, laborsaving, and can effectively avoid damaging single-deck.
The technical scheme that realizes the utility model purpose is: a kind of drawing-aid device, comprise crank, and it is characterized in that: have a pair of holding piece, two holding pieces are arranged symmetrically in an end of crank, have bolt to pass described two holding pieces.
And described holding piece one end is connected with crank, and the other end is connected with positive stop hook.
And described bolt root has screw thread, and the top is a smooth structure.
And described bolt root is threaded with a holding piece, and the top then places in the through hole on another holding piece.
And described crank, holding piece and the positive stop hook structure that is formed in one.
Advantage of the present utility model is: 1. use this drawing-aid device plug single-deck, and convenient, laborsaving.2. single-deck can accurately be in place.3. have positive stop hook, can effectively avoid damaging single-deck.

Embodiment
The utility model is described further below with reference to embodiment referring to Fig. 1～5.
The utility model relates to a kind of large-scale rack installation auxiliary device, and particularly a kind of drawing-aid device comprises crank 1, it is characterized in that: have the end that a pair of holding piece 2, two holding pieces 2 are arranged symmetrically in crank 1, have bolt 4 to pass described two holding pieces 2.
During use a pair of holding piece 2 is placed the both sides of single-deck 6 then bolt 4 to be passed holding piece 2 and single-deck 6 respectively, can realize the insertion of single-deck 6 and action such as extract in crank 1 this end application of force.
And described holding piece 2 one ends are connected with crank 1, and the other end is connected with positive stop hook 3.
When single-deck 6 inserts rack downwards; because it is hinged between single-deck 6 and the bolt 4; crank 1 this end will move downward; 3 of positive stop hooks that are in the other end are that fulcrum moves upward with bolt 4; after single-deck 6 insertions put in place; the top of positive stop hook 3 just marches to the spacing place 5 of rack guide rail, and it is dark so just to prevent that single-deck 6 from inserting, thereby reaches the purpose of protection single-deck 6.
Further technical scheme can be that described bolt 4 roots have screw thread, and the top is a smooth structure.
Because the thickness of holding piece 2 is less, if bolt 4 is the words that are threaded with two holding pieces 2,4 o'clock two holding pieces 2 of bolting on just might inwardly tighten up under bolt 4 drives, thereby generation deformation, therefore a root at bolt 4 is provided with screw thread, its root is threaded with a holding piece 2, and the other end places in the through hole on another holding piece 2, can prevent that holding piece 2 from deformation taking place bolting at 4 o'clock.
And described bolt 4 roots are threaded with a holding piece 2, and the top then places in the through hole on another holding piece 2.
Further technical scheme also can be described crank 1, holding piece 2 and positive stop hook 3 structure that is formed in one.
Crank 1, holding piece 2 and positive stop hook 3 are formed in one and can improve integrally-built steadiness, increase the service life.
Claims (5)
