Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: an automatic locking pneumatic gate valve comprises a gate frame 1, a telescopic cylinder 2, a limiting plate 7 and a push rod 9, wherein the telescopic cylinder 2 is arranged at the bottom of the gate frame 1 in a penetrating manner, a gate body 3 is arranged at the inner side of the gate frame 1 in a sliding manner, the bottom of the gate body 3 is fixedly connected to the top end of the telescopic cylinder 2, a reinforcing rib 4 is fixedly arranged above the front surface of the gate frame 1, a guide plate 5 is fixedly arranged below the middle part of the gate frame 1, a brush rod 6 is fixedly arranged above the middle part of the gate frame 1, the limiting plate 7 is fixedly arranged above the gate frame 1, a clamping block 8 is fixedly arranged at the middle part of the lower surface of the limiting plate 7, the push rod 9 is arranged at the right side of the inner part of the limiting plate 7 in a penetrating manner, the outer wall of the push rod 9 at the inner part of the limiting plate 7 is fixedly connected to the inner wall of the limiting plate 7 through a, the right side of the top of the inserting plate body 3 is provided with a clamping block 13 in a penetrating manner, and the outer wall of the clamping block 13 in the inserting plate body 3 is fixedly connected to the inner wall of the inserting plate body 3 through a third spring 14.

For vertical coaxial distribution setting between telescopic cylinder 2 and the picture peg frame 1, and mutually perpendicular sets up between the horizontal central line of picture peg frame 1 and telescopic cylinder 2's the vertical central line to telescopic cylinder 2's length is greater than the half of picture peg frame 1 length, makes telescopic cylinder 2 drive picture peg body 3 can not take place the dead condition of card with picture peg frame 1 when taking place to remove.

The length of picture peg body 3 is greater than 5 lengths to between the picture peg frame 1 top of deflector, and the length of

picture peg body

3 and 2 lengths of telescopic cylinder all are less than the length of picture peg frame 1, prevent to seal the space of picture peg frame 1 because of the not enough space of the length of picture peg body 3.

The strengthening rib 4 sets up for "X" font structure, and the deflector 5 of 4 bottoms of strengthening rib is "L" font structure setting to deflector 5 sets up about the vertical axis central axis symmetric distribution of picture peg body 3, makes deflector 5 carry out spacing centre gripping to picture peg body 3, prevents that picture peg body 3 from taking place the condition of controlling the displacement.

Be vertical coaxial distribution setting between limiting plate 7 and the picture peg body 3, and the grip block 8 of limiting plate 7 bottom surface sets up about the vertical center axis symmetric distribution of limiting plate 7 to the upper and lower width of limiting plate 7 is greater than the upper and lower length of fixture block 13, prevents to lead to the inside of picture peg body 3 and fixture block 13 unable entering limiting plate 7 because of the length overlength of fixture block 13.

The top surface of fixture block 13 sets up for the slant structure, and the sum of the width about width of fixture block 13 and the width about the picture peg body 3 is greater than the interval length between the grip block 8 of both sides to the length about the outside fixture block 13 of picture peg body 3 is less than the upper and lower height of push rod 9, makes grip block 8 equally can be because width setting between spacing to picture peg body 3, prevents that picture peg body 3 from breaking away from limiting plate 7 automatically.

The working principle is as follows: before the automatic locking pneumatic gate valve is used, the overall condition of the device needs to be checked firstly to determine that the device can normally work, according to the figure 1-5, firstly, when the flashboard frame 1 needs to be closed and sealed, as shown in figure 1, the flashboard frame 1 is manually and fixedly arranged on the outer wall of a required cabin body, so that the opening of the cabin body is superposed with the upper end of the flashboard frame 1, then the telescopic cylinder 2 fixedly arranged at the bottom of the flashboard frame 1 is started, a cylinder rod of the telescopic cylinder 2 drives the fixedly connected flashboard body 3 not to slide in a chute in the flashboard frame 1, when the flashboard body 3 slides to the bottom of a limiting plate 7 at the top of the flashboard frame 1, the flashboard body 3 is guided and limited by a clamping block 8 fixedly arranged at the bottom of the limiting plate 7, and the flashboard body 3 is prevented from entering the limiting plate 7 after the material in the cabin body, after the clamping block 13 in the right side of the inserting plate body 3 is limited by the clamping block 8, the clamping block 13 compresses the third spring 14 to enter the inserting plate body 3, after the inserting plate body 3 completely enters the limiting plate 7, the clamping block 13 extends outwards due to the extensibility of the third spring 14, the clamping block 13 is pushed out to be clamped with the inside of the limiting plate 7, the pushing block 12 limits the inserting plate body 3 and the clamping block 13 under the extension of the second spring 11, and the closing and sealing of the bin body are completed;

when needs open picture peg frame 1, at first push rod 9 through artificial with the positive central point of limiting plate 7 and put the department to limiting plate 7 inside promotion, make push rod 9 under the extension of first spring 10, with fixture block 13 to the inside extrusion of picture peg body 3, make picture peg body 3 have sufficient distance to break away from the inside of limiting plate 7, later break away from limiting plate 7 under the drive through telescopic cylinder 2, brush pole 6 in picture peg frame 1 is spacing down, brush the material on the 3 outer walls of picture peg body, prevent that the material adhesion from taking place the card on 3 outer walls of picture peg body and dying, lead to the not hard up condition of picture peg frame 1.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
