Description

Technical Field

[0001] The invention relates to the technical field of weapon equipment, and in particular to a lightweight latch body latch closing mechanism for a multi-tube launcher. Background Art

[0002] The launcher latch is located at the tail of the launcher and is used to close the launcher. It can withstand high pressure and achieve rapid opening and closing. Figure 1 As shown. The existing multi-barrel launcher latch is usually designed to have a locking structure installed around the latch. When the launcher needs to be lightweight, it is difficult to reduce the weight of the latch to ensure the locking strength to resist the impact of gunpowder. Summary of the invention

[0003] In view of this, the present invention provides a lightweight bolt body closing mechanism for a multi-tube launcher, which opens a hole in the center of the bolt body, adds a rotatable locking central support shaft, and uses it together with the inclined locking hook on the upper end, thereby achieving the effect of increasing the locking strength of the bolt body while achieving lightweight of the bolt body.

[0004] A multi-tube launcher lightweight bolt body bolt closing mechanism, comprising a central support shaft, a handle, a handle pressure rod, a handle spring, a pin shaft and a collar;

[0005] One end of the central support shaft and one end of the handle are embedded in each other and then installed in the ring, and the pin shaft radially passes through the ring, the handle and the central support shaft in sequence to fix the three together and then is installed in the center hole of the latch body; the handle pressure rod is elastically installed inside the handle through a handle spring, and the head of the handle pressure rod is located outside the handle; a radially protruding limit block is provided on the handle pressure rod; when the handle pressure rod is pressed downward along the handle axis, the limit block can rotate freely after being staggered from the limit groove on the shell; when the handle drives the central support shaft to rotate to the locked position, the other end of the central support shaft locks the latch body; after the handle pressure rod is released, the handle pressure rod pops outward, and the limit block enters another limit groove on the shell for limiting.

[0006] Furthermore, a locking tongue is processed on one end of the central support shaft, and a blind hole is processed on the end surface of the other end.

[0007] Furthermore, the handle is processed with a handle pressure rod mounting hole penetrating through the front and rear ends thereof, and the end of the handle that cooperates with the central support shaft is also processed with a blind hole.

[0008] Furthermore, the handle pressure rod is composed of two cylindrical sections with different diameters, a blind hole is processed on the end face of the large diameter cylindrical section, the blind hole is used to install the handle spring, and a radially protruding limit block is provided on the outer circle of the large diameter cylindrical section.

[0009] Furthermore, the housing is provided with two limiting grooves, one limiting groove is used for limiting the center support shaft before locking, and the other limiting groove is used for limiting the center support shaft after locking.

[0010] Beneficial effects:

[0011] 1. The present invention opens a hole in the center of the latch body, installs a rotary locking mechanism formed by a handle and a central support shaft in the central hole, and uses a handle pressure rod to realize the synchronous rotation and locking control of the handle and the central support shaft, and is used together with the inclined locking hook above, so as to achieve the effect of increasing the locking strength of the latch body while achieving lightweight of the latch body.

[0012] 2. A blind hole is processed on the end face of one end of the center support shaft of the present invention, and a blind hole is also processed on the end of the handle that cooperates with the center support shaft. The center support shaft and the handle are embedded through two blind holes. The center support and the handle can be assembled and connected by combining a ring and a pin shaft, making the assembly and connection more convenient and reliable. The blind hole of the center support shaft also provides an installation space for the handle spring.

[0013] 3. The present invention overcomes the drawback of the existing multi-tube launcher bolt body that the bolt body is difficult to reduce in weight due to the addition of locking structures around the bolt body. After multiple shooting tests, it has been verified that the bolt body can be effectively locked after adding the central support shaft, while also ensuring the structural strength of the bolt body, without deformation after shooting, and with excellent overall performance.

[0021] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0022] As attached Figure 2 , 3 As shown in Figure 4, the present invention provides a lightweight bolt body latching mechanism for a multi-tube launcher, the mechanism comprising a central support shaft 1, a handle 2, a handle pressure rod 3, a handle spring 4, a pin 5 and a collar 6, and the latching mechanism composed of the above components is installed in the central hole of the bolt body.

[0023] The central support shaft 1 has a locking tongue at one end and a blind hole at the other end. The handle 2 has mounting holes for the handle pressure rod 3 that run through its front and rear ends, and the end of the handle 2 that matches the central support shaft is also processed with a blind hole.

[0024] The handle pressure rod 3 is composed of two cylindrical sections with different diameters. A blind hole is processed on the end surface of the large diameter cylindrical section for installing the handle spring 4. A radially protruding limit stopper is provided on the outer circle of the large diameter cylindrical section.

[0025] The housing 7 mounted on the end surface of the latch body 9 has two limiting grooves, one of which is used for limiting the center support shaft 1 before locking, and the other is used for limiting the center support shaft 1 after locking.

[0026] One end of the center support shaft 1 with a blind hole and the other end of the handle 2 with a blind hole are embedded in each other and then installed into the ring 6. The pin 5 passes through the ring 6, the handle and the center support shaft in radial order, fixes the three together and then is installed in the center hole of the latch body. After the handle pressure rod 3 passes through the mounting hole on the handle, one section of the handle spring 4 is located in the blind hole of the handle pressure rod 3, and the other section of the handle spring 4 is located in the blind hole of the center support shaft 1. The head of the handle pressure rod 3 is located outside the handle 2. When the handle pressure rod 3 is pressed downward along the handle axis, the limit stopper can rotate freely after staggering the limit groove on the outer shell. When the handle 2 drives the center support shaft 1 to rotate to the locked position, the other end of the center support shaft 1 locks the latch body 9. After releasing the handle pressure rod 3, the handle pressure rod 3 pops outward, and the limit stopper enters another limit groove on the outer shell for limiting.

[0027] The status before and after locking is shown in the attached figure. Figure 5 and 6 As shown, push the handle pressure rod 3 to compress the handle spring 4, rotate the handle 2, drive the central support shaft 1 to rotate, and the central support shaft 1 changes from vertical to horizontal, locking the latch body. Loosen the handle pressure rod 3, the handle pressure rod 3 is reset under the action of the handle spring 4, and the locking hook 8 falls down, completing the complete locking of the latch body 9.

[0028] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
