Detailed description of the invention
Below in conjunction with Figure of description and embodiment, this utility model content is described in detail:
The reality of a kind of floor slab preformed hole cover board fixing device that this utility model provides as shown in Figure 1 to Figure 7 shows the
Execute illustration to be intended to.
A kind of floor slab preformed hole cover board fixing device, it includes cover plate 1 and is located at the flexible solid of cover plate 1 bottom
Determine assembly;
Described Telescopic Fixed assembly includes the fixed bin body 2 being fixedly arranged on cover plate 1 downside, is located at fixed bin body
Transfer gear 3 in 2 and two are divided into transfer gear 3 respective side and intermeshing with transfer gear 3
Rack bar 4, the corresponding sidewall of fixed bin body 2 offers and holds the passage that rack bar 4 stretches out;
It also includes being coaxially disposed with transfer gear 3 and being extended cover plate 1 upper side by transfer gear 3 top
Swing arm 6.
Operator drive transfer gear 3 to rotate by swing arm 6, transfer gear 3 and then driving rack bar 4
Protrude horizontally up fixed bin body 2 sidewall.When transfer gear 3 rotates, for adverse movement between two rack bars 4,
The outer end of final each rack bar 4 can bear against on the corresponding sidewall of reserved opening 81, plays fixing lid
The effect of plate 1.
It is also preferred that the left fixed bin body 2 should arrange the track guiding rack bar 4.
Swing arm 6 periphery is provided with fixed gear ring 21, and described fixed gear ring 21 is located on fixed bin body 2 or cover plate 1;
Swing arm 6 sidewall is provided with some ratchets 61 of coordinating spacing with fixed gear ring 21, and ratchet 61 and swing arm 6 it
Between be provided with elastic component 62.
Swing arm 6 sidewall offers the groove 63 for housing ratchet 61, and described elastic component 62 is positioned at groove 63
In.
It also includes the box spanner 7 coordinated with swing arm 6, and the cross section of swing arm 6 and box spanner 7 is just
Polygon.The longitudinal section of described ratchet 61 is the right-angled trapezium or right angled triangle just put, and its hypotenuse is outwardly.
When described box spanner 7 sleeve is on swing arm 6, extruding ratchet 61 is to contract.
It is anti-that being disposed to of ratchet 61 and fixed gear ring 21 prevents reserved opening 81 sidewall to rack bar 4
To active force so that this utility model is fixing the most firm.
Locking principle is as follows:
1. when box spanner is pressed for 7 times, move after promoting the ratchet 61 on swing arm 6 so that ratchet 61 is with solid
Determining gear ring 21 and depart from realization unblock, under this state, swing arm 6 can rotate freely under box spanner 7 drives.
