On support.In one embodiment, the spacing block set is connected in the main body by a swinging block.In one embodiment, institute
The opening that main body has the close swinging block is stated, the wall-mounted VMC (Ventilation Mechanical Control System) is also removable on the opening comprising being covered on
The cover plate for unloading.In one embodiment, slide block is connected with the swinging block, the slide block is located on the inside of main body and near institute
State opening.
In one embodiment, first limit assembly comprising be configured at multiple bolts in the main body and with the spiral shell
The multiple bolts hole in the mounting bracket that bolt position is adapted, each bolt have bolt head and the connection spiral shell
The screw rod of bolt head, each bolt hole have the first hole and the second hole being connected;The radial dimension of the bolt head is less than described
The aperture size in the first hole and the aperture size more than second hole, the radial dimension of the screw rod is less than second hole
Aperture size.
Using preceding solution, this utility model can use to obtain following technique effect:
After wall-mounted VMC (Ventilation Mechanical Control System) main body of the present utility model is installed on mounting bracket, the first limit assembly and second spacing
Component is all configured between main body and mounting bracket, it is to avoid prior art fixed structure exposes the problem for affecting product appearance.
Simultaneously for convenience of will disassemble on main body self installation support, can further by opening near swinging block is opened up in main body
Mouthful, carry out convenient use person and spacing block set is separated with spacing shrinkage pool.

Specific embodiment
Fig. 1 to Fig. 5 is refer to, the wall-mounted VMC (Ventilation Mechanical Control System) with concealed fastening mechanism of the present utility model includes main body
10th, mounting bracket 20, the first limit assembly 30 and the second limit assembly 40.
Main body 10 is VMC (Ventilation Mechanical Control System) main function components, and the Filterses and blower fan for purification of air are configured with inside which
Deng part.
Mounting bracket 20 is the part that mode is fixed on surface of wall such as can to tie up by screwed lock.
In the present embodiment, the first limit assembly 30 comprising the multiple bolts 31 being configured in main body 10 and with 31, bolt
Put the multiple bolts hole 32 in mounting bracket 20 being adapted.As shown in figure 3, each bolt 31 has bolt head 31A and company
The screw rod 31B of connecting bolt head 31, each bolt hole 32 have the first hole 32A and the second hole 32B being connected;The radial direction of bolt head 31A
Aperture size and aperture size more than second hole 32B of size H2 less than the first hole 32A, the radial dimension H1 of screw rod 31B are little
In the aperture size of the second hole 32B, and then when main body 10 is installed on mounting bracket 20, bolt head 31A can be first made to pass through first
Hole 32A, then main body 10 is overall moves down, and makes screw rod 31B be moved to the position of the second hole 32B, and then can cause bolt head
31A can pass through the spacing of the second hole 32B, reach and limit main body 10 X is mounted opposite the purpose of 20 activity of support in the horizontal direction.The
One limit assembly 30 can also adopt other structures.Horizontal direction X system described in the utility model is certainly
In the present embodiment, the first limit assembly 40 has a spacing block set 41 and spacing with what spacing block set 41 was adapted
Shrinkage pool 42, spacing block set 41 are configured in main body 10, and spacing shrinkage pool 42 is configured in mounting bracket 20.In the present embodiment, limit
Position projection 41 is connected in main body 10 by a swinging block 43.When main body 10 is installed on mounting bracket 20, spacing block set 41 engages
In spacing shrinkage pool 42, limit main body 10 vertically Y is mounted opposite the purpose of 20 activity of support to reach.
Main body 10 has the opening 10A near swinging block 43, and wall-mounted VMC (Ventilation Mechanical Control System) is also included and is covered on opening 10A
Dismountable cover plate 50.In the present embodiment, be connected with slide block 44 on swinging block 43, slide block 44 be located on the inside of body 10 and
Near opening 10A.When user self installation support 20 dismantles main body 10, cover plate 50 can be first dismantled, then be dialled by opening 10A
Dynamic slide block 44, swings 43 opposing body 10 of swinging block, with the spacing block set 41 that is connected on swinging block 43 from spacing recessed
Depart from hole 42, further the mobile main body 10 in vertically axial direction Y-direction again, main body is separated with mounting bracket 20.
When main body 10 is installed in mounting bracket 20, can first bolt 31 be directed at the first hole 31A, then by mounting bracket
Vertically axial direction Y moves down on 20 overall edges, and the bolt head 31A of bolt 31 is spacing by the second hole 32B, while spacing block set 41 blocks
Together in spacing shrinkage pool 42.
After wall-mounted VMC (Ventilation Mechanical Control System) main body of the present utility model is installed on mounting bracket, the first limit assembly and second spacing
Component is all configured between main body and mounting bracket, it is to avoid prior art fixed structure exposes the problem for affecting product appearance.
Simultaneously for convenience of will disassemble on main body self installation support, can further by opening near swinging block is opened up in main body
Mouthful, carry out convenient use person and spacing block set is separated with spacing shrinkage pool.Specific embodiment of the present utility model is above, its
