In order to improve the portability of the weapon system, multiple subsystems such as missiles, photoelectric devices, radars, etc. are integrated on a turret, and high-density integration design is adopted. Therefore, during the missile loading process, the installation position of the missile is often close to the adjacent equipment, and there is a safety problem. In order to ensure safety, if the distance between the missile and other equipment is simply increased, the system integration degree will be poor, which is also not a feasible solution.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the present application more clear and understandable, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0039] The present embodiment provides a manually expandable and retractable missile launcher, which is designed with two layers, including an expansion frame 2 and a support frame 1. When loading a missile, the expansion frame 2 can be expanded outward by 100 mm relative to the support frame 1. The expansion frame 2 is connected to the support frame 1 through four sets of rolling linear guide rails 4. The horizontal movement of the expansion frame 2 relative to the support frame 1 is realized by a trapezoidal screw transmission handle expansion mechanism 3. After the missile is loaded in place, the expansion frame 2 is retracted in place through the movement of the expansion mechanism 3, and is firmly locked through the stop block and the locking mechanism.

[0040] As shown in Figures 1-10 the missile launcher includes a support frame 1, an expansion frame 2, an expansion mechanism 3, rolling linear guide rails 4 (4), stop blocks 5 (2), locking mechanisms 6 (2), and a handle 7. The expansion mechanism 3 includes a base 31, bearings 32 (2), a first sleeve 33, a lead screw 34, a nut 35, a connecting flange 36, and an end shaft 37. The rolling linear guide rails 4 include guide rails 41 and sliding blocks 42. The locking mechanisms 6 include a first sleeve 61, a locking shaft 62, a small cap 63, and a spring 64. The handle 7 includes a handle body 71 and a rotating handle 72.

[0041] The connection relationship of the above-mentioned parts is that the support frame 1 is the mounting platform of the whole system, the connecting flange 36 of the unfolding mechanism 3 is fixed on the support frame 1 by bolts, the guide rail 41 of the rolling linear guide rail 4 is fixed on the support frame 1 by bolts, the stop block 5 is directly welded on the support frame 1, the locking mechanism 6 is fixed on the support frame 1 by the second sleeve 61, and the unfolding frame 2 is fixed on the sliding block 42 of the rolling linear guide rail 4 by bolts. The base 31 of the unfolding mechanism 3 is fixed on the unfolding frame 2 by bolts. When the horizontal unfolding and retraction of the unfolding frame 2 relative to the support frame 1 is carried out, the corresponding square hole on the handle main body 71 of the handle 7 is sleeved on the end shaft of the unfolding mechanism 3, and the rotating handle 72 on the handle 7 is rotated by the operator.

[0042] As shown in Figure 4 , the layout mode of the unfolding mechanism 3, the rolling linear guide rail 4 and the locking mechanism 6 along the support frame 1 is that the unfolding mechanism 3 is located at the middle position of the support frame 1, the rolling linear guide rail 4 is symmetrically arranged relative to the unfolding mechanism 3, two groups at a time, the distance between every two groups is 1308mm, the distance between the two guide rails in each group is 192mm, and the locking mechanism 6 is also symmetrically arranged relative to the unfolding mechanism 3, the distance between the two mechanisms is 800mm. At the same time, in order to reduce the height of the launching frame, the mounting position of the missile on the unfolding frame 2, that is, the middle position above a group of guide rails, is sunken, and the nesting design of the unfolding frame 2 and the rolling linear guide rail 4 is completed. The HJG-DA30CAL2H0 of Hanjiang Machine Tool Factory is selected for the rolling linear guide rail 4, in order to improve the connection rigidity, two sliding blocks are installed on a single guide rail, and the total bearing capacity of the four rolling linear guide rails can reach 3 tons.

[0043] The three-dimensional schematic view of the unfolding mechanism 3 is shown in Figure 5 . As shown in Figure 6 , the connection relationship of the parts of the unfolding mechanism 3 is that the nut 35 is fixed on the first sleeve 33 by bolts, the combination of the first sleeve 33 and the nut 35 is fixed on the base 31 by the bearing 32, the lead screw 34 is matched with the nut 35 by trapezoidal thread, and the thread specification is 28*5.

[0044] As shown in Figure 7 , the sliding block 42 of the rolling linear guide rail 4 can move along the guide rail 41, has large bearing capacity and small friction.

[0045] As shown in Figure 9 , the locking shaft 62 is installed in the interior of the second sleeve 61, can move axially along the second sleeve 61 through the shaft hole cooperation, and the spring 64 is installed in the closed space formed by the locking shaft 62 and the second sleeve 61; the second sleeve 61 is designed with locking and unlocking positions, the two positions are 90° to each other, as shown in Figure 8 .

[0046] AsFigure 10 As shown, the rotating handle 72 is sleeved on the crank main body 71 and can rotate relative to the crank main body 71.

[0047] The working process is as follows:

[0048] First, the unlocking and locking of the unfolding frame 2 are completed. When the locking mechanism 6 is in the locked state, the locking shaft 62 is extended and inserted into the pin hole of the unfolding frame 2, the operator holds the small cap 63 of the locking mechanism, pulls out the locking shaft 62 relative to the second sleeve 61, and rotates the locking shaft 62 by 90° to be unlocked and fixed when pulled to the limit position, so that the unlocking operation is realized. When the locking mechanism 6 is in the unlocked state, the operator holds the small cap 63 of the locking mechanism, rotates the locking shaft 62 by 90° relative to the second sleeve 61 to be unlocked and released, and the locking shaft 62 is automatically extended and inserted into the corresponding pin hole of the unfolding frame 2 under the action of the spring 64, so that the locking operation is realized.

[0049] Secondly, the horizontal unfolding of the unfolding frame 2 relative to the support frame 1 is completed. After confirming that the locking mechanism 6 is in the unlocked state, the operator sleeves the crank main body 71 of the crank 7 on the end shaft 37 of the unfolding mechanism 3, holds the rotating handle 72 of the crank 7 and rotates counterclockwise, and the unfolding frame 2 is unfolded horizontally relative to the support frame 1 under the driving of the unfolding mechanism 3 and the constraint of the rolling linear guide rail. Due to the stroke limitation, when the crank 7 cannot continue to rotate, the unfolding frame 2 is unfolded to the position, and after being unfolded to the position, the operator removes the crank 7.

[0050] Finally, the folding of the unfolding frame 2 is completed. The operator sleeves the crank main body 71 of the crank 7 on the end shaft 37 of the unfolding mechanism 3, holds the rotating handle 72 of the crank 7 and rotates clockwise, and the unfolding frame 2 is folded horizontally relative to the support frame 1 under the driving of the unfolding mechanism 3 and the constraint of the rolling linear guide rail 4. After being folded to the position, the corresponding position on the unfolding frame 2 is in close contact with the stop block 5, at this time, the locking mechanism 6 is used for reliable locking, and after the operation is completed, the operator removes the crank 7.

[0051] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application.
