Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.Wherein identical parts identical accompanying drawing
Mark represents.It should be noted that the word "front", "rear", "left", "right", the "up" and "down" that are used below in description refer to
It is the direction in accompanying drawing, word " bottom surface " and " top surface ", " interior " and " outer " are referred respectively to towards or away from particular elements geometry
The direction at center.
Embodiment 1, protective cover, as shown in Figure 1 and Figure 2, including shield window 2 and mounting assembly 3, shield window 2 are arranged on wall 1
On, the air port 11 for installing shield window 2 is offered on wall 1, shield window 2 includes window frame 21 and window leaf 22, some window leaves 22 etc.
Spacing is arranged in window frame 21.The outer rim of window frame 21 is provided with edge clipping 211, and after the installation of window 2 is protected, edge clipping 211 is stuck in air port 11
Outside.Mounting assembly 3 is arranged on the side that window frame 21 is in inside air port 11.
With reference to Fig. 3, mounting assembly 3 includes pilot hole 31, straight-tooth tie rod 32, mounting rod 33, shaft seat 34 and threaded block
35。
Pilot hole 31 is opened on window frame 21, and straight-tooth tie rod 32 is through pilot hole 31 and is meshed with mounting rod 33, rotating shaft
Seat 34 is fixed on window frame 21 and is rotationally connected with the one end of mounting rod 33, and threaded block 35 is also secured on window frame 21 and is threadedly coupled
In the other end of mounting rod 33, direction precession of the mounting rod 33 to the inwall of air port 11 and held out against when straight-tooth tie rod 32 is pulled outwardly.
First shield window 2 is installed on the air port 11 on wall 1, straight-tooth tie rod 32 is then pulled outwardly, forces and straight-tooth tie rod
32 mounting rods 33 being meshed rotate, and because the threaded one end of mounting rod 33 is connected with threaded block 35, cause mounting rod 33
Feed, so as to force direction precession of the mounting rod 33 to the inwall of air port 11 and hold out against.
Straight-tooth tie rod 32 need to be only promoted detachably to protect window 2.
When mounting assembly 3 is only provided with one group, complete to carry holding out against for the frame side of mounting assembly 3 on window frame 21,
Simultaneously this frame side can produce certain reaction force, make to window frame 21 also hold out against.
When mounting assembly 3 is provided with more than two, and it is oppositely arranged, the stability that can install window frame 21 is more preferable.
The optimal case of the present embodiment is the outer rim of window frame 21 four groups of mounting assemblies 3 of equidistantly distributed nearby.
For the ease of the pulling of straight-tooth tie rod 32, make the pulling more convenient power-saving of straight-tooth tie rod 32.In straight-tooth tie rod 32
On be provided be easy to pull draw ring 321.
As shown in figure 4, mounting rod 33 includes shaft 331, gear part 332, threaded portion 333 and precession portion 334.Rotating shaft
Portion 331, gear part 332, threaded portion 333 and precession portion 334 are a unified entirety, continuously distributed and coaxial.
Shaft 331 is rotationally connected with shaft seat 34, and gear part 332 engages with straight-tooth tie rod 32, and the screw thread of threaded portion 333 connects
Threaded block 35, precession portion 334 are connected to close to the outer rim of window frame 21 and can be stretched to the direction away from the center of window frame 21.
In order that mounting rod 33 can be directly screw into the inwall of air port 11, make mounting assembly 3 installation it is more stable can
Lean on.Precession portion 334 is arranged to taper and tapered thread is distributed thereon.
In order that shaft 331 is still rotatablely connected after being screwed in precession portion 334 with shaft seat 34.It is pre- to shaft 331
Stop enough length.
The cooperation of shaft 331 and threaded portion 333 can make mounting rod 33 while stable rotation, can allow mounting rod
33 feed.
After straight-tooth tie rod 32 is pulled outwardly and pulls out pilot hole 31, gear part 332 starts to rotate under the effect of straight-tooth tie rod 32,
Threaded portion 333 drives mounting rod 33 to occur to feed under the effect of threaded block 35 and revolves precession portion 334 after being rotated with gear part 332
It is tightened to the inwall of air port 11.
Straight-tooth tie rod 32 can pull straight out, and can both avoid the presence straight-tooth tie rod 32 that the side of window frame 21 is lofty,
The planarization of shield window 2 can be ensured.
Specifically used mode of the present utility model is：When protective cover is installed, it will first protect window 2 and be installed to air port on wall 1
On 11, the draw ring 321 that is then pulled outwardly on straight-tooth tie rod 32, gear part 332 is forced to start to rotate under the effect of straight-tooth tie rod 32,
Threaded portion 333 drives mounting rod 33 to occur to feed under the effect of threaded block 35 and revolves precession portion 334 after being rotated with gear part 332
It is tightened to the inwall of air port 11.So as to force direction precession of the mounting rod 33 to the inwall of air port 11 and hold out against.
When disassembly is desired, straight-tooth tie rod 32 is directly inserted into pilot hole 31, and is depressed into certain depth.
Specific embodiment is only that it is not to limitation of the present utility model, this area to explanation of the present utility model
Technical staff can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but only
All to be protected in right of the present utility model by Patent Law.
