Description

Technical Field

[0001] This invention relates to the field of gap adjustment technology, and more particularly to an adapter gap adjustment device, an adapter, and a missile launch box. Background Technology

[0002] The missile adapter is a crucial component of the missile ejection system. Existing missile adapters are installed inside the missile launch box, typically using an interference fit between the adapter's inner diameter and the missile's outer diameter. In practice, existing adapters are often designed using finite element analysis to calculate the adapter's thickness change during launch and then determine the pre-compression amount. However, because the gap between the existing adapter and the missile is not adjustable, an improperly designed adapter compression amount can render the entire adapter system unusable. Summary of the Invention

[0003] This invention provides an adapter gap adjustment device, an adapter, and a missile launch box, which can solve the technical problems in the prior art.

[0004] The present invention provides an adapter gap adjustment device, wherein the device includes a pad, a wedge seat, a wedge block and an adjustment base. The pad is used to connect the adapter and the wedge seat. The wedge block is movably disposed on the adjustment base and cooperates with the wedge seat to convert the horizontal displacement of the wedge block into the vertical displacement of the wedge seat, thereby driving the adapter to move.

[0005] Preferably, the device further includes a drive unit connected to the wedge block for driving the wedge block to move horizontally on the adjustment base.

[0006] Preferably, the device further includes a connecting nut and a guide block. The adjusting base includes a groove and a threaded hole on the side wall of the groove. The wedge block is movably disposed in the groove. The driving unit includes an adjusting rod and an adjusting wheel.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0022] like Figure 1-3 As shown, an embodiment of the present invention provides an adapter gap adjustment device, wherein the device includes a pad 2, a wedge seat 3, a wedge block 4 and an adjustment base 5. The pad 2 is used to connect the adapter 1 and the wedge seat 3. The wedge block 4 is movably disposed on the adjustment base 6 and cooperates with the wedge seat 3 to convert the horizontal displacement of the wedge block 4 into the vertical displacement of the wedge seat 3, thereby driving the adapter 1 to move.

[0023] Adapter 1 is used to prevent direct contact between the missile and the launch container. Its assembly with the missile can be an interference fit, and the material of adapter 1 can be polyester foam. During missile launch, adapter 1 slides out of the launch container together with the missile.

[0024] The above technical solution places the gap adjustment device inside the missile launch box. A pad connects the wedge seat to the adapter, and the wedge block, in cooperation with the wedge seat, drives the adapter to move vertically. This allows for adjustment of the adapter gap, avoiding the problem of the adapter being unusable due to an unadjustable gap.

[0025] More specifically, by moving the adapter, the gap between the adapter and the missile can be adjusted, thereby adjusting the amount of compression of the adapter.

[0026] According to one embodiment of the present invention, the pad 2 and the wedge-shaped seat 3 are connected by a screw connection.

[0027] For example, a countersunk hole can be drilled in the wedge seat, and a screw can be screwed into the pad through the countersunk hole of the wedge seat to achieve the connection.

[0028] According to one embodiment of the present invention, the device further includes a drive unit connected to the wedge block 4 for driving the wedge block 4 to move horizontally on the adjusting base 6.

[0029] That is, the wedge block is driven to perform horizontal reciprocating motion by the drive unit.

[0030] According to one embodiment of the present invention, the device further includes a connecting nut 6 and a guide block 7. The adjusting base 5 includes a groove and a threaded hole 11 disposed on the side wall of the groove. The wedge block 4 is movably disposed in the groove. The driving unit includes an adjusting rod 8 and an adjusting wheel 9. The adjusting rod 8 passes through the threaded hole 11 and includes a first threaded segment, a smooth segment, and a second threaded segment connected in sequence. The first threaded segment is connected to the adjusting wheel 9 and engages with the threaded hole 11. The second smooth segment has a shoulder at the connection point with the first threaded segment. The guide block 7 is disposed at the shoulder. The second threaded segment is connected to the wedge block 4 through the connecting nut 6 and limits the positioning of the guide block 7.

[0031] By operating the adjusting wheel, the adjusting rod can be made to push the wedge block to reciprocate within the adjusting base; by setting the guide block, the wedge block can be guided during its horizontal reciprocating motion.

[0032] By making the diameter of the second smooth segment smaller than the diameter of the first threaded segment, a shoulder can be formed at the connection between the second smooth segment and the first threaded segment.

[0033] According to one embodiment of the present invention, the device further includes a reset unit 10, the reset unit 10 including a mounting assembly and an elastic component disposed on the mounting assembly, the reset unit 10 being disposed in the bottom of the adjusting base 5 and in the guide limiting hole 12 of the side wall of the adjusting base 5, and the reset unit 10 in the guide limiting hole 12 being connected to the wedge-shaped seat 3.

[0034] For example, such as Figure 3 As shown, the bottom of the adjusting base can be provided with a protrusion with a through hole, through which a reset unit is installed. The opening direction of the through hole of the protrusion is the same as the opening direction of the guide limiting hole 12.

[0035] The position of the guide limiting hole corresponds vertically to the position of the reset unit at the bottom of the adjusting base, such as... Figure 3 As shown, the reset units positioned at the top and bottom form a set, working together to reset the adapter.

[0036] By incorporating a reset unit, the adapter can be returned to its original position through the action of elasticity when the gap is loosened. Furthermore, the reset unit, located in the guide limiting hole, can also cooperate with the guide limiting hole to achieve a guiding function while resetting.

[0037] According to one embodiment of the present invention, the mounting component is a bolt, and the elastic component is a pre-stretched spring.

[0038] For example, for each reset unit, a pre-stretched spring is connected to a bolt.

[0039] Therefore, when the gap is loosened, the adapter can be restored to its original position under the action of the spring tension.

[0040] According to one embodiment of the present invention, the guide limiting hole 12 is runway-shaped.

[0041] Those skilled in the art should understand that the above description of the shape of the hole is merely exemplary and not intended to limit the present invention.

[0042] The following is combined Figure 4A and Figure 4B The working process of the driving unit of the present invention will be described.

[0043] like Figure 4A and Figure 4BAs shown, the first threaded section corresponding to area a′ engages with the threaded hole 11 corresponding to area a in the adjusting base 5. By rotating the adjusting wheel 9, the adjusting rod can move forward and backward. Area b′ corresponds to the smooth section, with a diameter smaller than that of area a′. The shoulder formed from area a′ to area b′ limits the guide block 7 and wedge block 4 to area b′. The guide block 7 and wedge block 4 have through holes at the corresponding positions in area b (that is, the guide block 7 and wedge block 4 have through holes for the smooth section and the second threaded section to pass through). The diameter of the through hole is larger than that of the threaded rod in area b′ and smaller than that in area a′. The second threaded section corresponding to area c′ engages with the connecting nut 6, which has the same function as the shoulder, allowing the guide block 7 and wedge block 4 to reciprocate linearly with the adjusting rod 8.

[0044] More specifically, the adjusting wheel 9 drives the adjusting rod 8, which in turn drives the wedge block 4 to reciprocate in the horizontal direction; the upper surface of the wedge block 4 cooperates with the lower surface of the wedge seat 3 to achieve the reciprocating motion of the wedge seat 3 in the vertical direction.

[0045] Among them, the reset unit connected to the wedge seat 3 ( Figure 3 In the middle, the reciprocating motion of the reset unit located on the side wall of the adjusting base 5 within the guide limiting hole can guide the vertical movement of the wedge-shaped seat; the reset units located at the upper and lower positions are positioned to guide the wedge-shaped block 4. Figure 1 For example, when moving horizontally to the left, the wedge seat can move downwards under the action of spring force (that is, the adapter is reset when the gap is loosened).

[0046] This invention also provides an adapter, which includes the adapter gap adjustment device described in the above embodiments.

[0047] The present invention also provides a missile launch box, wherein the adapter described in the above embodiments is included.

[0048] like Figure 5 As shown, the adapter and adapter gap adjustment device 14 are installed on the missile launch box 13. When the missile 15 is vertically loaded into the missile launch box 13, the missile 15 can be fixed by the adapter gap adjustment device 14, and the adapter can be adjusted to an appropriate compression amount in preparation for missile launch.

[0049] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0050] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0051] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
