Description

Technical Field

[0001] The 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] In the solid-state laser driver of inertial confinement fusion, the sheet laser amplifier plays a vital role as its core component. Neodymium-doped phosphate glass is the core device of the amplifier. Working under high laser flux, it has extremely strict requirements on the cleanliness of its surface. In order to ensure normal operation, the inside of the amplifier must meet the cleanliness standard of no less than ISOClass 5, while the external environment can only reach the cleanliness level of ISOClass 7. Therefore, the sealing of the amplifier is a key technology.

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

[0004] The existing sealing structure usually relies on screw connection, which increases the difficulty of installation, disassembly and maintenance of the amplifier to a certain extent and is inefficient. Therefore, the industry urgently needs a new sheet laser amplifier sealing bottom plate structure that can ensure the sealing effect while simplifying the installation, disassembly and maintenance operations.

[0005] CN109326947A discloses a combined sheet-like 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 needs to pull the 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 linkage locking bottom plate that can be easily disassembled and assembled, and the installation or disassembly of the bottom plate can be completed with only one operation. Summary of the invention

[0006] The present invention provides a linkage 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 solution of the present invention is as follows:

[0008] A linkage locking sheet amplifier sealing bottom plate structure that is convenient to disassemble and assemble, which is characterized by including:

[0009] The bottom plate is used to support the entire structure and provide a stable sealing base for the amplifier. A circle of sealing ridges is arranged at the edge of the bottom plate, and a circle of sealing rings surrounding the sealing ridges is arranged outside the sealing ridges to ensure good sealing performance. The bottom plate also has a reserved interface for subsequent detection of the cleanliness of the box;

[0010] A driving slider mechanism, comprising a driving slider, a guide groove and a transmission rod, wherein the guide groove is mounted on the bottom plate, the driving slider can move along the guide groove, and the π-shaped sliding frame is controlled by an external power source, and the transmission rod is used to connect the driving slider and the π-shaped sliding frame, and synchronously transmit the linear motion of the driving slider to the π-shaped sliding frame;

[0011] The sliding linkage mechanism comprises 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 bottom plate;

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

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

[0014] Furthermore, the oblique edge of the π-shaped sliding frame and the guide groove of the wedge-shaped sliding block are in sliding cooperation, thereby ensuring that the movement of the π-shaped sliding frame can smoothly push the wedge-shaped sliding block 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 pulling force 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 to facilitate assembly and maintenance.

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

[0019] Furthermore, the locking rod is respectively fixed on the straight edge of the π-shaped sliding frame and the outer side of the wedge-shaped sliding block, and locking and unlocking 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-tensioning spring, and the π-shaped sliding frame is automatically pulled outward by the elastic force of the pre-tensioning 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] The present invention uses the above-mentioned structural design to realize the linkage control of the locking mechanism by the movement of the π-type sliding frame, thereby avoiding cumbersome tooling operations. At the same time, the preload spring provides a reliable locking force, ensuring that the amplifier sealing bottom plate has an excellent sealing effect during use, and can be quickly disassembled and assembled, thereby greatly improving the maintenance efficiency. Compared with CN109326947A, the present invention can realize convenient locking and unlocking of the entire bottom plate only by moving the driving slider. The present invention realizes convenient disassembly and assembly of the π-type sliding frame through the synergistic effect of the driving slider mechanism, the sliding linkage mechanism and the positioning locking mechanism. The user only needs to drive the driving slider through an external power source to easily control the movement of the π-type sliding frame, thereby realizing the locking and unlocking operation. Not only does it simplify the disassembly and assembly process, but it also improves the operating efficiency. In the sliding linkage mechanism, the matching design of the wedge-shaped slider and the guide rail enables the π-type sliding frame to push the wedge-shaped slider to slide along the guide rail when moving, thereby realizing locking and unlocking through the locking rod.

DETAILED DESCRIPTION

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

[0031] The present invention relates to a conveniently disassembled and assembled linked 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 the complexity of tooling. The present invention is further described below in conjunction with 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 sealing 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 bottom plate 1 provides a stable base for the entire device, ensuring the sealing and support of the amplifier during operation. The edge of the bottom plate 1 is provided with a sealing ridge 11, and a sealing ring 12 is provided around the outer periphery of the sealing ridge 11 to achieve a good sealing effect, prevent external gas or impurities from entering the interior of the device, and ensure the normal operation of the device. The bottom plate 1 reserves an interface 13 for subsequent detection of the cleanliness of the box.

[0034] like Figure 2 and Figure 3 As shown, the driving slider mechanism 2 is composed of a driving slider 21, a guide groove 22 and a transmission rod 23. The driving slider 21 moves along the guide groove 22 through 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 a straight side. It consists of a straight side 31 and an oblique side 32. The straight side 31 is fixed with a locking rod of a positioning and locking mechanism, and the oblique side 32 is inserted into a guide groove 42 of a wedge-shaped slider 41. With the movement of the π-shaped sliding frame 3, the oblique side 32 will push the wedge-shaped slider 41 to slide along the guide rail 43. The outer side of the wedge-shaped slider 41 is fixed with a locking rod of a positioning and locking mechanism, which can be locked and unlocked with the movement of the π-shaped sliding frame 3.

[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 on the bottom plate 1 and provides a motion track for the wedge-shaped slider 41. The bevel 32 is inserted into the guide groove 42 of the wedge-shaped slider 41, and the bevel 32 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 on the outside of the wedge-shaped slider 41, and locking and unlocking are achieved as the slider moves.

[0037] like Figure 6 and Figure 7 As shown, the positioning locking mechanism 5 is a general positioning locking mechanism, which is installed on the bottom plate and includes a lock housing 51, a lock rod 52 and a preload spring 53. The lock rod 52 is respectively fixed to the straight edge 31 of the π-type sliding frame 3 and the outer side of the wedge-shaped slider 41 of the sliding linkage mechanism 4, and is inserted into the lock hole 61 of the box body 6 with the movement of the π-type sliding frame 3 to complete the locking or unlocking function. The positioning locking mechanism 5 fixedly connected to the straight edge 31 of the π-type sliding 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-type sliding 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 to automatically tighten the π-type sliding frame 3 outward to ensure the reliability and stability of the positioning locking.

[0038] In actual operation, the user drives the driving slider 21 to move along the guide groove 22 through an external power source, and the transmission rod 23 transmits the linear motion of the driving slider 21 to the π-shaped sliding frame 3, so that it pushes the wedge-shaped slider 41 to move along the guide rail 43, and at the same time, the locking rod 52 of the positioning locking mechanism 5 fixed on the wedge-shaped slider 41 and the locking rod 52 of the positioning locking mechanism 5 fixed on the straight edge 31 of the π-shaped sliding frame 3 are linked to be inserted into the locking hole 61 of the box body 6 for locking or unlocking operations. The preload spring 53 provides a tensile force to automatically tighten the π-shaped sliding frame 3 outward, ensuring the reliability and stability of the positioning locking.

[0039] The 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 only through simple translation operation, making maintenance more convenient and improving work efficiency.
