Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1 to Figure 3, the automatic anti-drop device of a kind of top cover provided by the utility model, is mounted on air-conditioner set
Between top cover 1 and shell 2, including hook 3 and fastener component, hook 3 are mounted on top cover 1, and fastener component is fixed on air conditioner
On the shell 2 of group.
Wherein, hook 3 is made of the mounting portion 3a of top and the coupler body 3b of lower section being bent upwards, mounting portion 3a and top cover
It is fixedly connected between 1 side wall by multiple rivets 4.
Fastener component includes retaining ring 5, hook lid 6, pedestal 7 and elastic component 8.Wherein, hook lid 6 by two parallel side plate 6a and
The connecting plate 6b composition being connected between two side plate 6a, hook lid 6 is overall U-shaped, and connecting plate 6b is L shape, to wherein inside
Structural member plays a certain protective role.Hook lid 6 is welded by the splicing of muti-piece metal plate.Pedestal 7 is fixed on shell 2, bottom
Seat 7 is made of the fixed part 7a of lower section and the interconnecting piece 7b of top, passes through multiple rivets between fixed part 7a and the side wall of shell 2
10 are fixedly connected.Interconnecting piece 7b is in U-shape, and is connected between the two sides of interconnecting piece 7b and two side plate 6a of hook lid 6 by the rotation of axis 9
It connects, hook lid 6 can be rotated relative to pedestal 7 around axis 9.Retaining ring 5 is mounted on the top of hook lid 6, the both ends of retaining ring 5 and the two of hook lid 6
It is rotatablely connected between a side plate 6a by pin shaft 11.Elastic component 8 uses torsional spring, is sleeved on axis 9, elastic component 8 is mounted on hook lid 6
7 interconnecting piece 7b of two side plate 6a and pedestal two sides between axis 9 on, torsional spring is stuck in connecting plate 6b and the bottom of hook lid 6
Between seat 7, the elastic force of elastic component 8 is acted at the connecting plate 6b of hook lid 6.The position and retaining ring 5 of elastic component 8 and connecting plate 6b
The two sides up and down of axis 9 are located at, hook lid 6 can rotate under the elastic force effect of elastic component 8 around axis 9.
As shown in figure 4, for hook lid 6 under the elastic force effect of elastic component 8, top abuts against shell 2 before the closure of top cover 1
On side wall.When top cover 1 is closed, during hook 3 is pressed down on top cover 1, the retaining ring 5 at the top of fastener component is touched,
And rotating retaining ring 5 around axis 9, torsional spring is compressed at this time, and hook 3 is by the way that after retaining ring 5, retaining ring 5 is automatically multiple under the action of torsional spring
Position is simultaneously further caught in hook 3, realizes the locking between top cover and shell.Even if the locking mechanism of air conditioner unit top cover at this time
Leakage lock or failure, it is also ensured that top cover 1 will not be started or be fallen off upwards in vehicle operation, realize the secondary of top cover 1
Protection guarantees driving installation.When needing to open top cover 1 and being overhauled, it is only necessary to pull out retaining ring 5 manually and release retaining ring 5
Limit.The protective device is mounted on the outside of air conditioner unit top cover 1 simultaneously, and structurally and operationally simple, convenient for operation
Personnel's daily maintenance.
