1st, shown in 2.In disassembly process, firstly, since lid mount point is more, installs and be difficult to, during lid, all of mount point of aliging,
Bring certain difficulty in operation, secondly, the junction point quantity of different size lid is also not quite similar, more than ten at least, many
Then tens, install and unloading process is time-consuming very long.
Utility model content
The purpose of this utility model is to provide a kind of structure simply fast opening lid lock apparatus, solves swing-in lid peace
Dress and the time-consuming long problem of dismounting.
The purpose of this utility model is achieved through the following technical solutions：
A kind of fast opening lid lock apparatus, for connecting lid and eyelid covering, including reinforcing plate, strengthen connector one, poker, add
Strong ties part two, bolt, spring, described reinforcement connector one and described reinforcement connector two are hinged by described poker, constitute
One hinge structure, described poker is socketed with for limiting activity between described reinforcement connector one and described reinforcement connector two
Described spring, described reinforcement connector one is fixedly connected with described lid, described reinforcement connector two is connected with described plus
Strong plate, described reinforcing plate is the board of bending, and described reinforcing plate is connected with described eyelid covering by dismountable described bolt.
Preferably, described reinforcement connector one and described reinforcement connector two all have groove, and described poker passes through two
Described groove connects described reinforcement connector one and described reinforcement connector two, and described spring is placed on groove structure described in two
In the cavity becoming.
Preferably, described reinforcement connector one passes through rivet and described lid is connected.
Preferably, described reinforcement connector two passes through rivet and described reinforcing plate is connected.
The having the beneficial effects that of fast opening lid lock apparatus provided by the utility model, can reduce the airtight lid of swing-in with
The junction point of mouth frame is so that the airtight lid of swing-in can rapidly open and close, and does not affect the normally-open of lid, and
The bolt using is less, convenient and swift during dismounting, greatly improves work efficiency.

Specific embodiment
For making purpose, technical scheme and advantage that this utility model is implemented clearer, below in conjunction with this utility model
Accompanying drawing in embodiment, is further described in more detail to the technical scheme in this utility model embodiment.In the accompanying drawings, ad initio
To the element that same or similar label represents same or similar element or has same or like function eventually.Described reality
Applying example is a part of embodiment of the present invention, rather than whole embodiments.Embodiment below with reference to Description of Drawings is to show
Example property it is intended to be used for explaining this utility model, and it is not intended that to restriction of the present utility model.Based in this utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of not making creative work,
Broadly fall into the scope of this utility model protection.
Below in conjunction with the accompanying drawings this utility model fast opening lid lock apparatus are described in further details.
As shown in figure 3, a kind of fast opening lid lock apparatus that this utility model provides, for connecting lid 7 and eyelid covering 8, bag
Include reinforcing plate 1, strengthen connector 1, poker 3, strengthen connector 24, bolt 5, spring 6, strengthen connector 1 and strengthen even
Fitting 24 is hinged by poker 3, constitutes a hinge structure, and is socketed with poker 3 for limiting reinforcement connector 1
And strengthen the spring 6 of activity between connector 24, wherein, strengthen connector 1 and reinforcement connector 24 all selects to have groove,
Poker 3 passes through two groove connection reinforcement connectors 1 and strengthens connector 24, and spring 6 selects to be placed on the sky that two grooves are constituted
Intracavity, as shown in Fig. 3 or Fig. 4.Strengthen connector 1 away from poker 3 side select rivet be fixedly connected with lid 7 so that
This utility model fast opening lid lock apparatus are arranged in lid 7, are fixedly connected mode and also can use bolt connection.Strengthen connecting
The reinforcing plate 1 of bending is connected with part 24, this reinforcing plate 1 selects the trapezoidal board of two stringcourse bendings, i.e. trapezoidal board two
Base length is different, and board section is in several fonts, as shown in figure 3, strengthening connector 24 to pass through rivet interlacement trapezoidal
Reinforcing plate 1 is gone to the bottom side, and on trapezoidal reinforcing plate 1, bottom side is connected with eyelid covering 8 by dismountable bolt 5, and bolt 5 sequentially passes through
The plate nut 9 of riveting in reinforcing plate 1 and eyelid covering 8, by screw thread cooperation fixing both so that the bending of trapezoidal reinforcing plate 1
