Brief description of the drawings
The utility model is described in further detail below in conjunction with the embodiment that attached drawing provides.
Fig. 1 is the structural blast schematic diagram of the utility model；
Fig. 2 is the structure diagram of the doorframe of the utility model；
Fig. 3 is the structure diagram of the detachable protective cover plate of the utility model.
Embodiment
By the following examples, the utility model is described in further detail.
A kind of typical embodiment, as shown in Fig. 1 ~ 3：
A kind of protective airtight partition door for subway district drainage ditch device, including water pipe 1 and doorframe 2, the side of the doorframe 2
It is connected with water pipe 1；The opposite side of doorframe 2, which is connected with, can load and unload protective cover plate 3, and its：The detachable protective cover plate 3 passes through
Blocking device 4 and the opposite side of doorframe 2 are tightly connected, and sealing strip 5 is provided between detachable protective cover plate 3 and doorframe 2.
Blocking device 4 described in the utility model includes the lock ear 4-1 installed in 2 both sides of doorframe, with detachable protection
The lock tongue 4-2 that cover board 3 is rotatablely connected；The lock tongue 4-2 by lockhole 4-1-1 on lock ear 4-1 order can load and unload protective cover plate 3 with
Doorframe 2 is tightly connected.The cooperation clamping of lock tongue 4-2 and lockhole 4-1-1 can so be passed through so that 3 energy of detachable protective cover plate
It is close to doorframe, by the effect of sealing strip 5, realizes and be tightly connected.
The lower end that the doorframe 2 is connected side with detachable protective cover plate 3 has bottom installing plate 2-1, bottom installing plate
There is location hole 2-1-1, described load and unload on protective cover plate 3 has and the location hole 2-1-1 on the installing plate 2-1 of bottom on 2-1
The positioning column 3-1 being adapted, makes detachable protective cover plate 3 be installed with doorframe 2 and positions.Such positioning method, makes simply, and
It is and workable, it is only necessary to by positioning column 3-1 insertion location holes 2-1-1, it is possible to realize location and installation.The utility model
In, location hole 2-1-1 is used as the designing scheme of 2, naturally it is also possible to is 1 either 3 or the design of more.This reality
With new used positioning method, it can also be carried out by way of three sides are fitted with installing plate, so do energy
More realize the purpose of accurate positioning, but be also not limited thereto.
The aperture D of the lockhole 4-1-1 sides is from top to bottom tapered into, the aperture D of lockhole 4-1-1 opposite sides by up to
Lower gradually increase；Mandrel 6 is fixed with the detachable protective cover plate 3, the lock tongue 4-2 passes through mandrel 6 and detachable protection
Cover board 3 is rotatablely connected, and the both ends of lock tongue 4-2 are inserted into lockhole 4-1-1 respectively.In the utility model, using lockhole 4-1-1
The design equal with lock tongue 4-2 thickness of aperture D minimum values, can so be more advantageous to lockhole 4-1-1 and be engaged lock with lock tongue 4-2
Tightly, it will not produce along the axial vibration of water pipe 1, more seal.Between mandrel 6 and lock tongue 4-2, it is connected by spring washer with nut
Connect.In the utility model, the both ends of lock tongue 4-2 are all to have certain chamfering or fillet, are so more advantageous to operating, when
So, lock tongue 4-2 uses the design pattern of diamond shape, and the use for also allowing for material is saved and easily operated purpose.This practicality
The change of new its aperture of lockhole 4-1-1 D, is to achieve the purpose that varying aperture by the bevel edge of the inner edge in the outside of doorframe 2,
It is straight flange close to the inner edge of the lockhole 4-1-1 of 2 side of doorframe, and such design will not cause to produce flexural deformation when clamping,
It is more advantageous to sealing.
Handle 4-2-1 is also equipped with the lock tongue 4-2, the outside of handle 4-2-1 has spacing handle 7.Spacing handle 7
Not only play the role of handgrip, while can also play the role of handle 4-2-1 controls in spacing handle 7, prevent from rotating
Measure excessive, be deformed.Handle 4-2-1 and lock tongue 4-2 in the utility model be by being welded to connect, or integrally casting and
Into its handle 4-2-1 is easy to be rotatablely connected in the middle part of the side of lock tongue 4-2.
Described to load and unload the side that protective cover plate 3 is connected with water pipe 1 and be equipped with seal strip groove 3-2, sealing strip 5 is inlaid in sealing
