Description

Technical Field

[0001] This invention belongs to the field of launch box supporting equipment, and more specifically, relates to an automatic unlocking mechanism for launching box erection. Background Technology

[0002] When transporting products such as cylindrical launchers, a locking mechanism is required to prevent axial movement of the product during transport. During transport, the locking mechanism must be reliably locked to prevent axial movement of the locked object. When the launcher is about to be erected, the locking mechanism must be promptly unlocked to ensure that the launch of the unlocked object is not affected.

[0003] Patent searches revealed that existing locking mechanisms primarily employ two unlocking methods: manual unlocking and passive unlocking. Manual unlocking typically involves manually adjusting the locking mechanism to the unlocked state before the launch box is erected. This method is reusable but often complex. Passive unlocking, on the other hand, usually relies on airflow to erode the locking mechanism during launch, requiring high-quality materials that possess both strength and instantaneous melting capability. This method is designed for single-use only and also results in high material costs.

[0004] Accordingly, there is an urgent need for further improvements in this area to better meet the locking and unlocking requirements of modern launch boxes under complex operating conditions. Summary of the Invention

[0005] To address the aforementioned deficiencies or needs of existing technologies, the present invention aims to provide an automatic unlocking mechanism for launch box erection. By fully considering the characteristics and requirements of launch box usage under various complex working conditions, targeted improvements are made to the specific structure and configuration of the unlocking mechanism. Consequently, it can not only automatically unlock the locked body during erection without affecting subsequent launches, but also automatically lock during descent, effectively preventing axial movement of the locked body. Furthermore, the unlocking mechanism of the present invention has a compact structure, is easy to operate, and possesses sufficient strength to effectively prevent damage caused by large loads during transportation.

[0006] To achieve the above objectives, according to the present invention, an automatic unlocking mechanism for erecting a launch box is provided. This launch box is used for transporting and launching cylindrical products. The mechanism comprises a locking pin, a guide plate, an upper sliding guide rod, a hand-cranked unit, a lower sliding guide rod, and a pressure block, wherein:

[0007] A compression spring is installed inside the pressure block, and the downward sliding guide rod is inserted through the lower end hole of the pressure block, and then the whole assembly is installed at the lower end of the launch box;

[0008] The lower end of the upper sliding guide rod is connected with the upper end of the lower sliding guide rod and keeps up-and-down linkage, and the upper end of the upper sliding guide rod is connected with the lower end of the guiding plate and keeps up-and-down linkage; in addition, the hand-operated unit is arranged on the upper sliding guide rod and a worm gear structure is formed between the two, so that the up-and-down linkage of the upper sliding guide rod can be manually executed by independently operating the hand-operated unit.

[0009] The locking pin is connected with the cylindrical product as a force bearing unit, the interior of the guiding plate is provided with an upwardly extending guiding groove, a roller bearing is arranged in the guiding groove and connected with the locking pin and keeps linkage, so that the horizontal left-and-right linkage of the locking pin can be executed by the movement of the roller bearing in the guiding groove, thereby realizing the unlocking and locking of the cylindrical product.

[0010] Through the above design, in actual operation, when the launching box falls, the lower end surface of the lower sliding guide rod is pressed upward and presses the compression spring to drive the upper sliding guide rod and the guiding plate to move upward, thereby making the locking pin move to the left in the horizontal direction, thereby realizing the locking of the cylindrical product; when the launching box is erected, the lower end surface of the lower sliding guide rod is no longer pressed, the compression spring in the interior of the lower sliding guide rod becomes relaxed, so that the lower sliding guide rod itself moves downward, driving the upper sliding guide rod to move downward, thereby making the locking pin move to the right in the horizontal direction, thereby realizing the automatic unlocking of the cylindrical product.

[0011] Further preferably, the locking pin is directly formed by machining and then connected with the cylindrical product.

[0012] Further preferably, the interface of the locking pin is preferably plug-in or clamping type and is connected with the cylindrical product via a guide rod.

[0013] Further preferably, the guiding plate is preferably made of metal material.

[0014] Further preferably, the outer part of the upper sliding guide rod is preferably provided with a protective tube.

[0015] Further preferably, the upper sliding guide rod and the lower sliding guide rod are preferably made of stainless steel material.

[0016] Further preferably, the hand-operated unit is arranged on the upper sliding guide rod by screwing or welding.

[0017] Further preferably, each component of the mechanism is a modular structure.

[0018] Overall, compared with the prior art, the above technical scheme conceived by the present application, by redesigning the internal structure of the matching unlocking mechanism and its specific arrangement, can automatically complete the unlocking of the locked body during the erecting process, without affecting the subsequent launching, and can automatically lock during the landing process to prevent the locked product from moving axially. In addition, the mechanism has sufficient strength to prevent damage from loads during transportation, and has the advantages of compact structure, easy operation, low cost, safety and reliability, etc. BRIEF DESCRIPTION OF DRAWINGS

[0031] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0032] Figure 1 is a schematic diagram of the overall structure of the launching box vertical automatic unlocking mechanism in the unlocked state according to the present application, Figure 2 is a schematic diagram of the overall structure of the launching box vertical automatic unlocking mechanism in the locked state according to the present application. As shown in Figure 1 and Figure 2 The mechanism according to the present application mainly includes locking pin 2, guide plate 3, upper sliding guide rod 4, hand-operated unit 5, lower sliding guide rod 6 and pressing block 7 and other constituent elements, which will be explained one by one below.

[0033] Referring to Figure 1 and Figure 2 , the pressing block 7 is internally provided with a compression spring 8, and the lower sliding guide rod 6 is provided through the lower end hole of the pressing block 7 and then integrally installed at the lower end of the launching box;

[0034] The lower end of the upper sliding guide rod 3 is connected with the upper end of the lower sliding guide rod 6 and keeps up-and-down linkage, and the upper end of the upper sliding guide rod 3 is connected with the lower end of the guide plate 2 and keeps up-and-down linkage. In addition, the hand-operated unit 5 is arranged on the upper sliding guide rod 3 and forms a worm gear structure therebetween, so that the up-and-down linkage of the upper sliding guide rod 3 can be manually executed by independently operating the hand-operated unit 5;

[0035] The locking pin 1 is coupled with the cylindrical product as a force-bearing unit, the guide plate 2 is internally provided with an upwardly extending guide groove, a roller bearing is installed in the guide groove and connected with the locking pin 1 and keeps linkage, so that the roller bearing moves in the guide groove to drive the locking pin 1 to execute left-and-right linkage in the horizontal direction, thereby realizing unlocking and locking of the cylindrical product.

[0036] The setting mode and manufacturing mode of each constituent element will be described more specifically below. Figures 3a-3f ​

[0037] The locking pin 1 and the guide plate 2 can be machined, and then the locking pin 1 and the roller bearing inside the guide plate 2 can be connected and fixed by a pin. The upper sliding guide rod 3 can also be machined, and the lower end of the guide plate 2 can be connected to the upper sliding guide rod 3 (either by screwing or welding). The lower end of the upper sliding guide rod 3 is threaded and cooperates with the worm gear in the hand crank mechanism 5 to form a worm gear mechanism. When the automatic unlocking and locking fail, the upper sliding guide rod 3 can be moved up and down by shaking the turntable through the worm gear to achieve the purpose of unlocking and locking.

[0038] The pressure block 7 can be machined and connected to the launch box to fix the mechanism. The compression spring 8 is installed inside the pressure block 7. Then, the upper end of the lower sliding guide rod 6 is fixed to the hand crank mechanism 5 (either by screwing or welding). The lower end of the lower sliding guide rod 6 passes through the pressure block 7 (through the spring) and the sealing plate is installed to complete the assembly.

[0039] In addition, when locked, the locking pin 1 passes through the guide rail and is inserted into the locking hole of the cylindrical product to complete the locking. Since the locking pin 1 is in direct contact with the guide rail, the force generated by the axial movement of the cylindrical product can be shared by the guide rail, which increases the reliability of the locking pin 1.

[0040] The following will combine Figure 4 and Figure 5 This will explain in detail the working process and operating mechanism of the present invention.

[0041] In actual operation, when the launch box falls, the lower end face of the lower sliding guide rod 6 is squeezed and moves upward, squeezing the spring and driving the hand crank mechanism 5, which in turn drives the upper sliding guide rod 3 and the guide plate, so that the locking pin 1 completes automatic locking.

[0042] When the launch box is erected, the lower end face of the lower sliding guide rod 6 is no longer compressed, and the internal compression spring becomes relaxed, causing the lower sliding guide rod 6 to move downward. At the same time, it can also drive the hand crank mechanism 5 and the upper sliding guide rod 3 to move downward, thus achieving automatic unlocking.

[0043] In summary, compared with existing devices, the automatic unlocking mechanism for launching box erection according to the present invention has a compact overall structure, high reliability, is easy to install and use, and has strong environmental adaptability. It can not only automatically complete the unlocking operation of the locked body during the erection process without affecting subsequent launch, but also automatically lock during the descent process and effectively prevent the locked body from axial movement. Therefore, it is particularly suitable for various complex working conditions such as the transportation and launch of cylindrical products.

[0044] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
