[0031] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Please refer to Figures 1 to 12 As shown: Embodiment 1: The present invention provides a high-temperature hanger for use inside a ceramic sintering furnace, comprising a support assembly and a hanger assembly, wherein the support assembly is composed of a plurality of mounting mechanisms 1, and the hanger assembly is composed of a connecting mechanism 2 and an opening and closing mechanism 3; The mounting mechanism 1 includes a support rod 101, a transmission rod 102 and a positioning seat 103. The head and tail of the support rods 101 of the multiple mounting mechanisms 1 are detachably fixedly connected to each other, and the transmission rod 102 is rotatably connected to the inside of the support rod 101. The support rods 101 of the multiple mounting mechanisms 1 are transmission-connected to each other, and the positioning seat 103 is inserted into the inside of the support rod 101. The support rod 101 of the bottom mounting mechanism 1 is installed inside the ceramic sintering furnace through the connecting piece 4. The connecting mechanism 2 includes a fixing seat 201 and a hanging frame 202. The fixing seat 201 is fixedly mounted on the side of the support rod 101, and the hanging frame 202 is rotatably connected to the side of the fixing seat 201. The hook body of the hanging frame 202 is a "U"-shaped design. The opening and closing mechanism 3 includes a closing rod 301, a first retaining rod 302, a second control rod 303 and a linkage rod 304. The closing rod 301 is rotatably connected to the notch of the hanging frame 202, and the first retaining rod 302 is inserted into the inside of the hanging frame 202, the second control rod 303 is inserted into the inside of the hanging frame 202, and the linkage rod 304 is inserted into the inside of the second control rod 303. The first retaining rod 302 can only move in a straight line along the axial direction of the rotation of the closing rod 301 inside the hanging frame 202, and the support assembly and the hanging assembly are both made of high temperature resistant materials.

[0033] In the disclosed embodiment, four groups of hanger assemblies are arranged in a circular array on the outside of each support rod 101, and the number is not limited to four groups, and the number can be increased or decreased. In use, four groups of hanger assemblies are arranged on the outside of each support rod 101, and each group of hanger assemblies can be hung with one or more substrates, and can be freely combined and used through a suitable number of mounting mechanisms 1, so that different numbers of substrates can be hung and positioned and sintered at one time, which is convenient and flexible to use.

[0034] In the embodiment of the present disclosure, a retaining protrusion 3011 is provided inside the closing rod 301, and a spiral retaining groove 3021 is provided inside the first retaining rod 302, the retaining protrusion 3011 is inserted into the retaining groove 3021, and a neutral spring 3022 is provided on the side of the first retaining rod 302, and the two ends of the neutral spring 3022 respectively abut against the inside of the first retaining rod 302 and the inside of the hanging frame 202, and two neutral springs 3022 are provided, and the two neutral springs 3022 are symmetrically arranged on both sides of the first retaining rod 302. Under the action of the two neutral springs 3022, when the closing rod 301 is not moved by external force, the retaining protrusion 3011 is located at the middle groove body of the retaining groove 3021. In use, the hanging assembly has a limiting structure, which can effectively prevent the hanging assembly or the support from being stuck. The support assembly causes the substrate to fall when it moves, and the installation and removal of the substrate on the hanger assembly can be directly completed by manually plugging and unplugging the substrate. When the hanger assembly is in the reset state, the positioning seat 103 is located at the bottom of the support rod 101, and a positioning gear 2021 is provided on the outside of the rotating shaft of the hanger frame 202, and a positioning rack 1031 is provided on the side of the positioning seat 103. The positioning rack 1031 and the positioning gear 2021 are meshed and transmitted, so that under the cooperation of the positioning rack 1031 and the positioning gear 2021, the hanger frame 202 is in a horizontal use state. At this time, the closing rod 301 is not subject to external force, so that under the positioning action of the two middle springs 3022, the closing rod 301 is in a vertical downward use state, thereby closing the gap of the hanger frame 202 and ensuring stable processing.

[0035] The locking cam 3022 is provided on the locking cam 3041 of the locking cam 3042, and the locking cam 3043 is provided on the locking cam 3042 of the locking cam 3043. The first retaining rod 3021 drives the first retaining rod 302 to move to one side and compresses the middle spring 3022 on the same side. In this process, since the control rod 3042 cannot move outward under the limiting action of the control groove, the synchronous gear 3012 can drive the second control rod 303 to move outward and stretch the overall tension spring 3041 through the synchronous rack 3031, so as not to block the inward rotation of the closing rod 301. When the substrate is completely hung on the hanger rack 202, the resistance of the substrate to the closing rod 301 disappears, and the compressed middle spring 3022 will automatically extend and reset, so that the closing rod 301 will also automatically reset and return to a vertical state for use, closing the gap of the hanger rack 202, ensuring that the substrate will not fall off the hanger rack 202 during the sintering process, and the use is stable. After the closing rod 301 is reset, the second control rod 303 will also be reset synchronously under the action of the overall tension spring 3041, which is stable and easy to operate.

[0036] In the disclosed embodiment, a control groove is provided on the side of the fixing seat 201, and a control rod 3042 is provided on the outside of the linkage rod 304. The control rod 3042 is inserted into the inside of the control groove, and the control groove is composed of a horizontally arranged outward expansion avoidance groove 2011 and an inclined outward expansion linkage groove 2012. The top of the outward expansion linkage groove 2012 is connected to one end of the outward expansion avoidance groove 2011. When the closing rod 301 is not moved by external force, the control rod 3042 is located at the connection between the outward expansion linkage groove 2012 and the outward expansion avoidance groove 2011. In use, when the substrate is sintered and part of the substrate needs to be removed, the substrate to be removed only needs to be directly pulled out of the hanging rack 202 to realize the disassembly operation of the substrate and the hanging rack 202. When the substrate is pulled out, it will interfere with the closing rod 301 and drive the closing rod 301 to rotate outward without hindering the pull-out operation of the substrate. When the closing rod 301 rotates outward , when the retaining protrusion 3011 is used, the first retaining rod 302 can be driven to move to the other side through the retaining groove 3021 and compress the middle spring 3022 on the same side, and in this process, the integral tension spring 3041 maintains the second control rod 303 and the linkage rod 304 as a whole, so that when the closing rod 301 rotates outward, the synchronous gear 3012 can drive the second control rod 303 and the linkage rod 304 to move inward through the synchronous rack 3031, and the control rod 3042 can move inside the extension avoidance groove 2011, and the device will not be stuck, and the use is stable. When the substrate is completely pulled out of the interior of the hanger rack 202, the resistance of the substrate to the closing rod 301 disappears, and the compressed middle spring 3022 automatically extends to drive the closing rod 301, the second control rod 303 and the linkage rod 304 to reset, so as to prepare for the next installation and hanging operation of inserting the substrate into the hanger rack 202, which is convenient and flexible to use.

[0037] In the embodiment of the present disclosure, a thread is provided in the middle of the rod body of the transmission rod 102, and the transmission rod 102 is screwed into the interior of the positioning seat 103 through the rod body thread. In use, when all the substrates after sintering need to be removed at one time, the opening action of all the opening and closing mechanisms 3 can be realized through the connecting mechanism 2, and the notch portion of the hanging rack 202 can be switched to a vertical downward state, so that all the substrates can be dropped and removed at one time, which is convenient for collection and subsequent processing operations. When the transmission rod 102 is rotated, the transmission rod 102 can drive the positioning seat 103 to move up and down inside the support rod 101 through the rod body thread, and the transmission rods 102 of adjacent installation mechanisms 1 can be synchronously transmitted, so only the top transmission rod 102 needs to be rotated. When the positioning seat 103 moves upward, the positioning rack 1031 can drive the hanging rack 202 to rotate downward through the positioning gear 2021, so as to The notched part is used downward. At the same time, during the rotation of the hanger rack 202, the control rod 3042 can drive the second control rod 303 to move outward through the linkage rod 304 under the action of the outward linkage groove 2012. Since the elastic force of the overall tension spring 3041 is greater than the elastic force of the mid-position spring 3022, when the linkage rod 304 and the second control rod 303 move outward, the synchronous rack 3031 can drive the closing rod 301 to rotate outward through the synchronous gear 3012, thereby opening the bottom notch of the hanger rack 202. From then on, all substrates will lose the limiting effect of the closing rod 301 and the hanger rack 202 on them, and then the substrates can be dropped uniformly to realize the operation of collecting after disassembly. It is convenient and flexible to use, and the downward movement of the positioning seat 103 can realize the reset operation of all hanger components, so as to prepare for the subsequent installation and sintering processing of the substrates, and it has strong flexibility and adaptability.

[0038] Specific usage and function of this embodiment: In the present invention, four groups of hanging components are arranged on the outside of each support rod 101, and each group of hanging components can hang one or more substrates, and can be freely combined and used by a suitable number of mounting mechanisms 1, so as to realize the operation of hanging and positioning different numbers of substrates and sintering them at one time in the sintering furnace. The hanging components have a limiting structure, which can effectively prevent the hanging components or supporting components from causing the substrates to fall off when moving, and the installation and removal of the substrates on the hanging components can be directly completed by manually plugging and unplugging the substrates. When the hanging components are in the reset state, the positioning seat 103 is located at the bottom of the support rod 101, so that under the cooperation of the positioning rack 1031 and the positioning gear 2021, The hanging frame 202 is in a horizontal use state, at which time the closing rod 301 is not moved by an external force, so that under the positioning action of the two middle springs 3022, the closing rod 301 is in a vertical downward use state, thereby closing the gap of the hanging frame 202. When it is necessary to install and hang the substrate on the hanging frame 202, it is only necessary to make the reserved hole on the substrate contact the closing rod 301 to realize the operation of hanging the substrate on the hanging frame 202. When the substrate contacts the closing rod 301, the closing rod 301 can rotate toward the inside of the hanging frame 202 under the contact action of the substrate, thereby avoiding blocking the hanging operation of the substrate, and when the closing rod 301 rotates, the maintaining protrusion 3011 can drive the first retaining rod 302 to move to one side through the retaining groove 3021 and compress the same side. The middle spring 3022 is automatically stretched and reset, so that the closing rod 301 is automatically reset to a vertical state for use, and the gap of the hanging rack 202 is closed, so that the substrate will not fall off the hanging rack 202 during the sintering process, and the use is stable, and the closing rod 301 will not fall off the hanging rack 202 after being reset. Under the action of the overall tension spring 3041, the second control rod 303 will also reset synchronously. When the substrate is sintered and part of the substrate needs to be removed, the substrate to be removed only needs to be pulled out of the hanger frame 202 to realize the disassembly operation of the substrate and the hanger frame 202. When the substrate is pulled out, it will conflict with the closing rod 301 and drive the closing rod 301 to rotate outward without hindering the pulling-out operation of the substrate. When the closing rod 301 rotates outward, the retaining protrusion 3011 can drive the first retaining rod 302 to move to the other side through the retaining groove 3021 and compress the middle spring 3022 on the same side. In this process, the overall tension spring 3041 maintains the second control rod 303 and the linkage rod 304 as a whole, so that when the closing rod 301 rotates outward,The synchronous gear 3012 can drive the second control rod 303 and the linkage rod 304 to move inward through the synchronous rack 3031, and the control rod 3042 can move inside the extension avoidance groove 2011 without getting stuck, and the use is stable. When the substrate is completely pulled out of the interior of the hanger rack 202, the resistance of the substrate to the closing rod 301 disappears, and the compressed middle spring 3022 automatically extends to drive the closing rod 301, the second control rod 303 and the linkage rod 304 to reset, so as to prepare for the next installation of the substrate into the hanger rack 202. When all the substrates after sintering need to be removed at one time, the opening action of all the opening and closing mechanisms 3 can be realized through the connecting mechanism 2, and the notch of the hanging frame 202 can be switched to a vertical downward state, so that all the substrates can be dropped and removed at one time, which is convenient for collection and subsequent processing operations. When the transmission rod 102 is rotated, the transmission rod 102 can drive the positioning seat 103 to move up and down inside the support rod 101 through the rod body thread, and the transmission rods 102 of adjacent installation mechanisms 1 can be synchronized. The transmission is carried out by rotating the transmission rod 102 at the top. When the positioning seat 103 moves upward, the positioning rack 1031 can drive the hanging frame 202 to rotate downward through the positioning gear 2021, so that the notch is used downward. At the same time, during the rotation of the hanging frame 202, the control rod 3042 can drive the second control rod 303 to move outward through the linkage rod 304 under the action of the outward linkage groove 2012. Since the elastic force of the overall tension spring 3041 is greater than the elastic force of the middle spring 3022, when the linkage When the moving rod 304 and the second control rod 303 move outward, the synchronous rack 3031 can drive the closing rod 301 to rotate outward through the synchronous gear 3012, thereby opening the bottom gap of the hanging rack 202, so that all substrates will lose the limiting effect of the closing rod 301 and the hanging rack 202 on them, and then the substrates can be uniformly dropped to realize the operation of collection after disassembly, which is convenient and flexible to use, and the downward movement of the positioning seat 103 can realize the reset operation of all hanging components, so as to prepare for the subsequent installation and sintering of the substrates.
