Description

Detachable shutter for locomotive

Technical Field

The invention relates to the technical field of shutters, in particular to a detachable shutter for a locomotive.

Background

The louver window is used as a type of window, is not beautiful and energy-saving, protects privacy, is widely applied in daily life, and is generally provided with an opening mechanism which is divided into a manual opening mechanism and a pneumatic opening mechanism. However, the manual opening and the pneumatic opening both need to arrange a connecting rod structure to realize the operation of opening, and the pneumatic opening still needs to arrange a pipeline, an electromagnetic valve and the like, the two opening mechanisms can cause the installation space of the shutter to be larger, a certain element in the opening mechanisms is damaged, the shutter fails to work, the shutter cannot be normally opened, the ventilation effect cannot be realized, the shutter is required to be kept in a normally open state at a position where the shutter is required to be opened, the opening mechanisms are not needed, and the shutter adopting the opening mechanisms can cause resource waste.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides a detachable blind for a locomotive.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a locomotive is with dismantling shutter, includes window frame and blade, blade both ends fixed mounting on the window frame, blade both ends internally mounted has the chock, is provided with the fluting on the chock.

According to another embodiment of the invention, the window frame is further provided with a mounting hole corresponding to the slot on the chock.

According to another embodiment of the present invention, it further comprises that the mounting hole is composed of a large circular hole and a small circular hole, and the large circular hole and the small circular hole are arranged on the same straight line.

According to another embodiment of the invention, the size of the slots arranged at the two ends of the chock block is consistent with the size of the large round hole and the small round hole on the corresponding window frame.

According to another embodiment of the present invention, further comprising the blade is fixedly installed on the window frame at an angle greater than or equal to 45 degrees with respect to the horizontal plane.

The invention has the advantages that the blades are fixed on the window frame through the chock blocks, a connecting rod mechanism is not required to be arranged, the required installation space is smaller, and each blade is independently installed, so that the condition that the shutter is invalid due to the damage of a certain element is avoided, an opening mechanism is omitted, the shutter is suitable for being installed in a place where the shutter is required to be in a normally open state, and the resource waste is avoided.

Drawings

The invention is further illustrated with reference to the following figures and examples.

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural view of a chock of the present invention;

fig. 3 is a schematic view of the structure of the window frame of the present invention.

In the figure, 1, a window frame, 2, a blade, 3, a chock block, 4, a groove, 5, a mounting hole, 6, a large round hole and 7, a small round hole are arranged.

Detailed Description

Referring to fig. 1, which is a schematic structural view of the present invention, a detachable blind for a locomotive includes a window frame 1 and blades 2, wherein both ends of the blades 2 are fixedly installed on the window frame 1, and plugs 3 are installed inside both ends of the blades 2.

As shown in fig. 2, which is a schematic structural diagram of a chock of the present invention, fig. 3 is a schematic structural diagram of a window frame of the present invention, a slot 4 is provided on the chock 3, a mounting hole 5 corresponding to the slot 4 on the chock 3 is provided on the window frame 1, the mounting hole 5 is composed of a large circular hole 6 and a small circular hole 7, the large circular hole 6 and the small circular hole 7 are arranged on the same straight line, the size of the slot 4 provided at both ends of the chock 3 is the same as the size of the large circular hole 6 and the small circular hole 7 on the corresponding window frame 1, and the blade 2 is fixedly mounted on the window frame 1 at an included angle greater than or equal to 45 degrees with the horizontal plane.

The working principle of the invention is as follows: the two ends of each blade 2 are internally provided with the chock blocks 3, the bolts penetrate through the large round holes 6 on the window frame 1 and the corresponding slots 4 on the chock blocks 3, the nuts on the bolts are screwed down to fix the blades 2 on the inner side of the window frame 1, and each blade 2 is independently installed, convenient to detach and convenient to maintain and replace. Adopt self-tapping screw again to pass corresponding fluting 4 on little round hole 7 and the chock 3 on window frame 1, screw up self-tapping screw, with window frame 1 and 3 fixed connection of chock, ensure that chock 3 can not rotate, can confirm the angle of blade 2 with this, when blade 2 and window frame 1 are installed, blade 2 becomes the contained angle installation that is more than or equal to 45 degrees with the horizontal plane, the opening is downward, can effectively prevent the rainwater to get into, this kind of shutter is applicable to and installs and be in normally open state at needs shutter, need not the place of opening mechanism, the wasting of resources has been avoided. When the temperature is higher, the material can expand, the screw penetrating through the mounting hole 5 on the window frame 1 and the slot 4 on the chock 3 is loosened by loosening the nut of the screw fixed on the chock 3, the screw can be adjusted in position on the slot 4 of the chock 3 in a small range, so that the mounting position of the blade 2 is correspondingly adjusted, the nut is screwed after the mounting position is determined, and the shutter can be used in an area with larger temperature difference.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
