Description

Technical Field

[0001] The utility model relates to the technical field of missile launching tubes, in particular to an emergency manual knob for a cover opening device of a missile launching tube. Background Art

[0002] In modern warfare, missiles, as high-precision, long-range strike weapons, have become a vital component of military power. A missile launch tube is a specialized cylindrical device used to hold and launch missiles. It primarily consists of a hatch and an inner tube. It supports, stores, and launches missiles. When the missile is in storage and transportation, the launch tube lid is closed, playing a crucial role in protecting the missile body and electrical interfaces from external forces and maintaining a sealed environment within the tube. When the missile is ready for launch, the lid must be able to be quickly opened to clear the missile's flight path and facilitate the missile's optical seeker's early target lock. Currently, the main lid opening solutions for missile launch tubes include mechanical, ejectable, and frangible lid technologies.

[0003] Mechanical lid opening utilizes manual or electric drive, using a transmission mechanism to open the lid. This method offers repeatable functionality and maintainability. However, manual lid opening takes a long time, making it unsuitable for rapidly changing operational environments. Electric lid opening, in complex environments, can be susceptible to interference or circuit damage, leading to lid opening failure.

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

[0006] In order to solve the above problems, the technical solution of the utility model is: an emergency manual knob for a missile launch tube cover opening device, comprising a fixed base, the fixed base, quick hand screws on both sides of the fixed base, a mounting ring on the top of the fixed base, an O-ring on the outside of the mounting ring, a knob above the fixed base, a dial wheel above the knob, a knob assembly screw behind the knob and the dial wheel, and device fixing screws at the four corners of the fixed base.

[0007] Furthermore, bosses are provided on both sides of the fixed base, and threaded holes for matching quick hand screws are opened in the two bosses.

[0008] Furthermore, the outer ring of the mounting ring is provided with a sealing groove, and the O-ring is clamped in the sealing groove.

[0009] Furthermore, a polygonal inner hole is provided inside the knob, threaded holes 1 are provided on both sides of the dial wheel and both sides of the knob, and the knob assembly screw is connected to the threaded hole 1 by a threaded structure.

[0010] Furthermore, the four corners of the fixed base are provided with threaded holes two for use with the fixing screws of the device.

[0011] Furthermore, a spoon-shaped handle is provided on the front side of the thumbwheel, and wings are provided on both sides of the thumbwheel.

[0012] The advantages of the present invention over existing technologies are as follows: the emergency manual knob designed by the present invention has the advantages of simple structure, small space occupation, convenient and quick operation, etc. It uses the simplest means to effectively solve the problem of quickly switching to manual operation mode when the electric drive device of the missile launch tube cover is damaged or fails.

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0019] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0021] like Figures 1 to 4As shown, an emergency manual knob for opening the cover of a missile launch tube comprises a fixed base 1, quick hand screws 2 are provided on both sides of the fixed base 1, bosses are provided on both sides of the fixed base 1, threaded holes for matching the quick hand screws 2 are provided in the two bosses, two threaded holes for matching the fixing screws 7 of the device are provided at the four corners of the fixed base 1, a mounting ring is provided on the top of the fixed base 1, an O-type sealing ring 3 is provided on the outside of the mounting ring, a sealing groove is provided on the outer ring of the mounting ring, the O-type sealing ring 3 is clamped in the sealing groove, and the sealing groove is used to fix the O-type sealing ring 3, which has a sealing protection function when it is not activated, a knob 4 is provided above the fixed base 1, and the quick hand screws 2 play a role in rotating the device when it is not activated. The button 4 is suspended on the fixed base 1. The inner hole of the knob 1 is made into a polygon, which can be adapted to the end drive shaft of various types of cover opening devices. A dial wheel 5 is provided above the knob 4, and a knob assembly screw 6 is provided behind the knob 4 and the dial wheel 5. Threaded holes are provided on both sides of the dial wheel 5 and both sides of the knob 4. The knob assembly screw 6 is connected to the threaded hole 1 with a threaded structure. The knob 4 and the dial wheel 5 are fixed by the knob assembly screw 6. Device fixing screws 7 are provided at the four corners of the fixed base 1, a spoon-shaped handle is provided on the front side of the dial wheel, and wings are provided on both sides of the dial wheel. The spoon-shaped handle facilitates manual rotation operation, and the wings are used to lock the quick hand-tightening screws. When the device is not enabled (when the quick hand-tightening screws are limited), the spoon-shaped handle cannot be rotated.

[0022] according to Figures 1 to 4 In the illustrated embodiment of the emergency manual knob for the missile launch tube cover opening device, a knob 4 with an O-ring 3 is inserted below the fixed base 1. A knob assembly screw 6 is used to fasten a dial wheel 5 and the knob 4 above the fixed base 1 to form a knob assembly. After the knob 4 assembly is pushed upward, two quick-tightening screws 2 are screwed into the boss screw holes of the fixed base 1. The protruding portions of the screws engage the wings of the dial wheel 5, causing the knob 4 assembly to float on the fixed base 1 to form an emergency knob device. This device is then installed at the end of the launch tube cover drive device.

[0023] When starting the device, first unscrew the two quick-tightening screws 2, then press the knob 4 assembly downward into the rotating shaft of the cylinder cover drive device, and turn the spoon-shaped handle of the dial wheel 5 to manually rotate the rotating shaft of the cylinder cover drive device to manually open or close the missile launch cylinder cover. The wing design of the dial wheel 5 can make the knob assembly float on the fixed base. Its function is to not affect the operation of the original drive device when the device is not enabled.
