Description

Technical Field

[0001] The present invention belongs to the field of high-power solid-state lasers, and in particular relates to a novel, conveniently disassembled and assembled linked locking sheet amplifier sealed bottom plate structure. Background Art

[0002] As a core component of the solid-state laser driver for inertial confinement fusion, the laser amplifier plays a crucial role. Neodymium-doped phosphate glass, the core component of the amplifier, operates under high laser flux, placing extremely stringent requirements on its surface cleanliness. To ensure proper operation, the amplifier's interior must meet a cleanliness standard of at least ISO Class 5, while the external environment can only meet ISO Class 7 cleanliness standards. Therefore, sealing the amplifier is a key technology.

[0003] The exterior of an amplifier is typically designed as a cleanroom box with an opening at the bottom. All components are lifted from the bottom of the box by a cleanroom trolley, and the entire bottom of the box is then sealed. Therefore, the sealing performance of the amplifier depends primarily on the sealing effect of the cleanroom box bottom cover.

[0004] Existing sealing structures typically rely on screw connections, which increases the difficulty of amplifier installation, removal, and maintenance, resulting in low efficiency. Therefore, the industry urgently needs a new sealing baseplate structure for chip laser amplifiers that can ensure effective sealing while simplifying installation, removal, and maintenance operations.

[0005] CN109326947A discloses a combined sheet-type laser amplifier bottom cover structure, which adopts a locking mechanism to replace the traditional screw connection, which reduces the difficulty of installation, disassembly and maintenance to a certain extent. However, each locking mechanism requires pulling a pull rod separately to achieve locking and unlocking, and there are usually multiple locking mechanisms on a bottom plate. Faced with the number of bottom plates that need to be disassembled and assembled for each installation, disassembly and maintenance, the efficiency is still low. There is an urgent need for a linked locking bottom plate that can be easily disassembled and assembled, so that the installation or disassembly of the bottom plate can be completed in just one operation. Summary of the Invention

[0006] The present invention provides a linked locking sheet amplifier sealing bottom plate structure that is convenient to disassemble and assemble, aiming to overcome the deficiencies of the prior art, achieve convenient disassembly and assembly, and reduce the difficulty of matching tooling.

[0007] The technical solutions of the present invention are as follows:

[0008] A conveniently disassembled and assembled interlocking locking sheet amplifier sealed bottom plate structure is characterized by including:

[0009] The bottom plate is used to support the entire structure and provide a stable sealing base for the amplifier. The edge of the bottom plate is provided with a circle of sealing ridges, and a circle of sealing rings is provided around the sealing ridges to ensure good sealing performance. The bottom plate also reserves an interface for subsequent inspection of the cleanliness of the box;

[0010] A drive slider mechanism includes a drive slider, a guide groove, and a transmission rod. The guide groove is mounted on the base plate. The drive slider can move along the guide groove and is driven by an external power source to control the π-shaped sliding frame. The transmission rod is used to connect the drive slider and the π-shaped sliding frame and synchronously transmit the linear motion of the drive slider to the π-shaped sliding frame.

[0011] The sliding linkage mechanism includes a wedge-shaped slider and a guide rail for the wedge-shaped slider to slide, wherein the wedge-shaped slider is provided with a guide groove, and the guide rail is fixed to the base plate;

[0012] A positioning locking mechanism is installed on the base plate;

[0013] The π-shaped sliding frame consists of a straight edge and two beveled edges, each of which is fixed at one end to the straight edge. The beveled edges can slide in the guide groove. As the π-shaped sliding frame moves, the beveled edges push the wedge-shaped slider to slide along the guide rail. A locking rod is fixed to the outside of the wedge-shaped slider, which is locked and unlocked as the slider moves.

[0014] Furthermore, the oblique side of the π-shaped sliding frame and the guide groove of the wedge-shaped slider are in sliding fit, ensuring that the movement of the π-shaped sliding frame can smoothly push the wedge-shaped slider to slide along the guide rail.

[0015] Furthermore, the locking rod of the positioning locking mechanism is inserted into the locking hole of the box body in the locked state to fix the sealing bottom plate, and in the unlocked state, the locking rod is withdrawn from the locking hole to allow the sealing bottom plate to be disassembled.

[0016] Furthermore, one end of the preload spring is fixed to the straight edge of the π-shaped sliding frame, and the other end is fixed to the lock housing of the positioning locking mechanism, providing continuous tension to ensure the reliability and stability of the positioning locking.

[0017] Furthermore, the base plate, driving slider mechanism, π-shaped sliding frame, sliding linkage mechanism and positioning locking mechanism are all modularly designed, which is convenient for assembly and maintenance.

[0018] Furthermore, the sealing ring is made of elastic material.

[0019] Furthermore, the locking rods are respectively fixed on the straight edge of the π-shaped sliding frame and on the outside of the wedge-shaped slider, and lock and unlock are completed with the movement of the π-shaped sliding frame. The positioning locking mechanism connected to the straight edge of the π-shaped sliding frame is provided with a pre-tightening spring, which automatically pulls the π-shaped sliding frame outward through the elastic force of the pre-tightening spring to ensure the positioning locking effect.

[0020] Furthermore, when the external power source is an electric drive device, it also includes a control circuit for controlling the electric drive device to achieve automatic control.

[0021] Through the above-mentioned structural design, the present invention utilizes the movement of the π-shaped sliding frame to achieve interlocking control of the locking mechanism, avoiding cumbersome tooling operations. Furthermore, the preloaded spring provides reliable locking force, ensuring excellent sealing of the amplifier's sealed base plate during use and enabling quick assembly and disassembly, significantly improving maintenance efficiency. Compared to CN109326947A, the present invention conveniently locks and unlocks the entire base plate simply by moving the drive slider. The present invention facilitates assembly and disassembly of the π-shaped sliding frame through the synergistic effect of the drive slider mechanism, the sliding linkage mechanism, and the positioning locking mechanism. Users simply drive the drive slider via an external power source to easily control the movement of the π-shaped sliding frame, thereby achieving locking and unlocking operations. This not only simplifies the assembly and disassembly process but also improves operational efficiency. In the sliding linkage mechanism, the coordinated design of the wedge-shaped slider and the guide rail enables the π-shaped sliding frame to push the wedge-shaped slider along the guide rail during movement, thereby achieving locking and unlocking via the locking rod.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention is explained in detail below with reference to the accompanying drawings and embodiments, but this should not limit the scope of protection of the present invention.

[0031] The present invention relates to a conveniently disassembled and assembled interlocking locking sheet amplifier sealing bottom plate structure, aiming to provide a bottom plate sealing structure that can simplify the disassembly and assembly process and reduce tooling complexity. The present invention is further described below with reference to the accompanying drawings and specific examples, but is not intended to limit the present invention.

[0032] like Figure 1 As shown, the convenient disassembly and assembly linkage locking sheet amplifier sealed bottom plate structure of the present invention includes a bottom plate 1, a driving slider mechanism 2, a π-shaped sliding frame 3, a sliding linkage mechanism 4, and a positioning locking mechanism 5.

[0033] The base plate 1 provides a stable foundation for the entire device, ensuring the amplifier's seal and support during operation. The edge of the base plate 1 is provided with a sealing ridge 11, and a sealing ring 12 is positioned around the outer periphery of the sealing ridge 11 to achieve a good seal, preventing external air and impurities from entering the device and ensuring normal operation. The base plate 1 also has a reserved interface 13 for subsequent testing of the cabinet's cleanliness.

[0034] like Figure 2 and Figure 3 As shown, the driving slider mechanism 2 consists of a driving slider 21, a guide groove 22 and a transmission rod 23. The driving slider 21 moves along the guide groove 22 by an external power source (such as a motor or a manual control device), and the movement of the driving slider is transmitted to the π-shaped sliding frame 3 through the transmission rod 23.

[0035] like Figure 4 and Figure 6 As shown, the π-shaped sliding frame 3 is a π-shaped structure consisting of two oblique sides and one straight side. It comprises a straight side 31 and an oblique side 32. A locking rod of a positioning and locking mechanism is fixed to the straight side 31, while the oblique side 32 is inserted into a guide groove 42 of a wedge-shaped slider 41. As the π-shaped sliding frame 3 moves, the oblique side 32 pushes the wedge-shaped slider 41 along a guide rail 43. A locking rod of the positioning and locking mechanism is fixed to the outside of the wedge-shaped slider 41, enabling locking and unlocking as the π-shaped sliding frame 3 moves.

[0036] like Figure 5 and Figure 6 As shown, the sliding linkage mechanism 4 includes a wedge-shaped slider 41, a guide groove 42, and a guide rail 43. The wedge-shaped slider 41 slides along the guide rail 43, which is fixed to the base plate 1 and provides a motion trajectory for the wedge-shaped slider 41. The bevel 32 is inserted into the guide groove 42 of the wedge-shaped slider 41 and can slide in the guide groove 42. As the π-shaped sliding frame moves, the bevel 32 pushes the wedge-shaped slider 41 to slide along the guide rail 43. A locking rod is fixed to the outside of the wedge-shaped slider 41, which is locked and unlocked as the slider moves.

[0037] like Figure 6 and Figure 7 As shown, the positioning locking mechanism 5 is a conventional positioning locking mechanism, mounted on the base plate, and comprises a lock housing 51, a lock rod 52, and a preload spring 53. The lock rod 52 is respectively fixed to the outside of the straight edge 31 of the π-shaped slide frame 3 and the wedge-shaped slider 41 of the sliding linkage mechanism 4. As the π-shaped slide frame 3 moves, it is inserted into the lock hole 61 of the housing 6 to perform the locking or unlocking function. The positioning locking mechanism 5, fixedly connected to the straight edge 31 of the π-shaped slide frame 3, is equipped with a preload spring 53. One end of the preload spring 53 is fixed to the straight edge 31 of the π-shaped slide frame 3, and the other end is fixed to the lock housing 51 of the positioning locking mechanism 5. The preload spring 53 provides a tensile force that automatically pulls the π-shaped slide frame 3 outward, ensuring the reliability and stability of the positioning locking.

[0038] During operation, the user uses an external power source to drive slider 21 along guide slot 22. Transmission rod 23 transmits the linear motion of slider 21 to π-shaped carriage 3, pushing wedge-shaped slider 41 along guide rail 43. Simultaneously, locking rod 52 of positioning and locking mechanism 5, secured to wedge-shaped slider 41 and to straight edge 31 of π-shaped carriage 3, is controlled to insert into locking hole 61 of housing 6 to lock or unlock the locking mechanism. Preload spring 53 provides tension, automatically pulling π-shaped carriage 3 outward, ensuring reliable and stable positioning and locking.

[0039] The present invention is suitable for sealing requirements of various sheet amplifiers and has the characteristics of simple structure, easy operation, stability and reliability. It can be installed and disassembled through simple translation operation, making maintenance more convenient and improving work efficiency.
