Description

Technical Field

[0001] The utility model relates to the technical field of missile launching tubes, in particular to a dustproof louver for a missile launching tube cover opening hinge. Background Art

[0002] Missiles are the most widely used weapons in modern warfare, featuring diverse platforms and models, and possessing both offensive and defensive capabilities. A missile is a weapon that carries a warhead, is propelled by its own power unit, and is guided and controlled by a guidance system. It can track targets and autonomously adjust its flight trajectory based on the relative position between the missile and the target, used to attack enemy targets. A missile launch tube is a cylindrical device that holds and launches missiles. It primarily consists of an inner tube, a housing, and a hatch.

[0003] Currently, missile launch tube lids primarily have mechanical opening and closing mechanisms, breakable lids, and drop-type opening and closing mechanisms. Common mechanical opening and closing mechanisms are manually or electrically actuated, utilizing a transmission mechanism to open and close, providing reusability. However, the hinged transmission mechanism of the electrically actuated opening and closing mechanism is partially located at the outer end of the tube. In harsh environments, large amounts of dust or sand can often enter the teeth, causing them to jam or become stuck. This can prevent the lid from opening and closing properly, impacting the launch process. To address this issue, we have developed a dustproof shutter for the missile launch tube lid opening hinge.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a missile launch tube cover opening hinge dustproof louver, which can prevent dust and sand from the hinge transmission teeth when the missile launch tube cover is opened or closed, thereby ensuring the normal operation of the hinge teeth.

[0006] In order to solve the above problems, the technical solution of the utility model is: a dustproof shutter for opening the cover of a missile launch tube, comprising a shutter first, a groove first being provided in the middle of the shutter first, and bosses first being provided at both ends of the shutter first;

[0007] The second louver page has a second groove in the middle, and two bosses are provided at both ends of the second louver page. The first boss is slidably connected to the two ends of the inner portion of the second louver page.

[0008] The third louver page has a groove in the middle, and two ends of the third louver page are provided with bosses, and the bosses are slidably connected to the two ends of the interior of the third louver page;

[0009] The louver four, the boss three is slidably connected to the two ends inside the louver four.

[0010] Furthermore, screw one is slidingly provided inside groove one, and screw one is threadedly connected to louver two. Screw two is slidingly provided inside groove two, and screw two is threadedly connected to louver three. Screw three is slidingly provided inside groove three, and screw three is threadedly connected to louver four.

[0011] Furthermore, one end of the louver is provided with a mounting plate 1, and the mounting plate 1 is provided with a countersunk hole 1; one end of the louver is provided with a mounting plate 2, and the mounting plate 2 is provided with a countersunk hole 2.

[0012] Furthermore, countersunk bolts are provided inside the first countersunk hole and the second countersunk hole.

[0013] Furthermore, the one hundred page, the two hundred page, the three hundred page, and the four hundred page are all arc-shaped.

[0014] The advantages of this utility model compared with the existing technology are:

[0015] (1) The material of the utility model is a composite high-strength aluminum alloy, which is resistant to high temperature and corrosion while taking into account the role of external force protection, and can effectively avoid the effects of external forces such as sand and dust or even stone impact; the structure adopts a multi-stage louver superposition form, which has good ductility and can effectively avoid the possible stacking of traditional protective covers, greatly improving the accident of the protective cover getting stuck in the launch hinge; the louver protective cover adopts a combined transmission form of an intermediate groove slide rail and a side wall slide rail at both ends, which can largely avoid the occurrence of single-piece louver protective cover detachment and reduce the vibration noise between multiple louver protective covers; the structure is compact, occupies little space and the single-piece processing technology is simple, and the louver protective cover can be produced by aluminum alloy casting combined with fine processing.
