Description

Technical Field

[0001] The present invention belongs to the technical field of quartz tubes, and particularly relates to a new type of quartz tube structure with both ends closed. Background Art

[0002] Limited by the inherent characteristics of the quartz tube, when it is in use, it will face various usage situations, but not limited to the following one. More specifically, especially during the processing and production of the quartz tube, it is necessary to perform a closing treatment on it. The traditional method of sealing the quartz tube is to use a quartz tube plug that is used in conjunction with it to achieve the closing treatment of the quartz tube.

[0003] Due to the low connection strength at the connection between the conventional quartz tube plug and the quartz tube, when subjected to external force or excessive internal pressure in the quartz tube, it is extremely easy for the quartz tube plug to separate from the quartz tube, thereby affecting the normal use of the quartz tube.

[0004] Combining the above, it can be found that when the existing quartz tubes on the market are closed, it is very difficult to avoid the problems mentioned above, and thus it is impossible to achieve the desired effect. Therefore, we have proposed a new type of quartz tube structure with both ends closed that can close both ends of the quartz tube and improve the connection strength when in use. Summary of the Invention

[0005] The purpose of the present invention is directed to a new type of quartz tube structure with both ends closed. Its advantage is that by setting a closed sleeve, due to the double-tubular structure with an inner tube provided inside the closed sleeve, the inner tube structure can contact the inner wall of the quartz tube body, and the outer tube structure is sleeved on the surface of the quartz tube body. Through the setting of the positioning mechanism, under the combined use of the fitting component and the locking component, the closed sleeve can be positioned at both ends of the quartz tube body, and the inner wall of the closed sleeve can contact the end face of the quartz tube body, improving the sealing performance of the two ends of the quartz tube body and completing the preliminary closing treatment of the quartz tube body. And through the setting of the fastening mechanism, under the combined use of the rotating component and the contact component, the closed sleeve can be restricted at both ends of the quartz tube body, so that the closed sleeve will not separate from the quartz tube body when subjected to external force or excessive pressure inside the quartz tube body, thereby ensuring the closing effect of the closed sleeve on the quartz tube body all the time.

[0006] The above technical object of the present invention is achieved by the following technical solutions: A new type of quartz tube structure with both ends closed, including a quartz tube main body, a closed sleeve, and a closing structure. The closed sleeves are respectively sleeved on the top and bottom surfaces of the quartz tube main body. The closing structure includes a positioning mechanism and a fastening mechanism. The positioning mechanism includes a fitting component and a locking component. The fitting component is rotatably connected inside the closed sleeve. The locking component is sleeved on the surface of the fitting component. One side of the locking component close to the closed sleeve is bolted to the closed sleeve. The fastening mechanism includes a rotating component. The rotating component is sleeved on the surface of the fitting component. One end of the rotating component is rotatably connected to a contact component. One side of the contact component close to the surface of the quartz tube main body is in close contact with the quartz tube main body.

[0007] By adopting the above technical solutions, by setting the closed sleeve, due to the double-tubular structure with an inner tube provided inside the closed sleeve, the inner tube structure can contact the inner wall of the quartz tube main body, and the outer tube structure is sleeved on the surface of the quartz tube main body. Through the setting of the positioning mechanism, by the combined use of the fitting component and the locking component, the closed sleeve can be positioned at both ends of the quartz tube main body, and the inner wall of the closed sleeve can be made to contact the end face of the quartz tube main body, improving the sealing performance of the two ends of the quartz tube main body being closed, and completing the preliminary closing treatment of the quartz tube main body. And through the setting of the fastening mechanism, and by the combined use of the rotating component and the contact component, the closed sleeve can be restricted at both ends of the quartz tube main body, so that the closed sleeve will not be separated from the quartz tube main body due to external force or excessive pressure inside the quartz tube main body, thus ensuring that the closed sleeve always has a closing effect on the quartz tube main body.

[0008] The present invention is further configured as follows: The fitting component includes a screw rod. The screw rod is rotatably connected inside the closed sleeve. A limit sleeve is sleeved on the surface of the screw rod. A nut sleeve is threadedly connected to the surface of the screw rod. A contact plate is rotatably connected to the surface of the limit sleeve. The contact plate is rotatably connected to the nut sleeve. One side of the contact plate close to the inner wall of the quartz tube main body is in close contact with the quartz tube main body. The screw rod is used in combination with the locking component.

[0009] By adopting the above technical solutions, by setting the fitting component, when the closed sleeve is sleeved on the quartz tube main body, the screw rod can rotate inside the closed sleeve and the limit sleeve, so that the nut sleeve moves on the surface of the screw rod and pushes the contact plate to move, enabling the contact plate to be adjusted from a retracted state to an open state, so that the contact plate can contact the inner wall of the quartz tube main body, positioning the closed sleeve at both ends of the quartz tube main body, and making the inner wall of the closed sleeve contact the end face of the quartz tube main body, improving the sealing performance of the two ends of the quartz tube main body being closed, and completing the preliminary closing treatment of the quartz tube main body.

[0010] The present invention is further configured such that: the contact plate is rotationally connected in a ring shape on the surface of the limit sleeve, wedge-shaped blocks are provided at both the top and bottom of the inner wall of the quartz tube main body, a contact portion is provided on one side of the contact plate close to the wedge-shaped block, and the contact portion is in close contact with the wedge-shaped block.

[0011] By adopting the above technical solution, by providing the wedge-shaped blocks, it is convenient for the contact portions on the contact plate to contact with them, thereby facilitating the positioning of the closed sleeve and preventing it from separating from the quartz tube main body randomly.

[0012] The present invention is further configured such that: connecting frames are bolted in a ring shape on the surfaces of both the screw sleeve and the limit sleeve, a connecting rod is rotationally connected between the opposite sides of the two connecting frames, and the contact plate is rotationally connected to the screw sleeve and the limit sleeve respectively through the connecting frames and the connecting rod.

[0013] By adopting the above technical solution, by providing the connecting frames and the connecting rod, the contact plate can be rotationally connected to the screw sleeve and the limit sleeve, thereby facilitating the screw sleeve to drive the contact plate to adjust to a retracted or expanded state.

[0014] The present invention is further configured such that: the locking assembly includes a fixed ring, the fixed ring is sleeved on the surface of the screw rod, one side of the fixed ring close to the closed sleeve is bolted to the closed sleeve, fixing rods penetrate through both sides inside the fixed ring, one side of the fixing rod close to the screw rod extends into the inside of the screw rod, the other side of the fixing rod extends outside the fixed ring and is bolted to a connecting plate, a locking tension spring is sleeved on the surface of the fixing rod, and the sides of the locking tension spring close to the fixed ring and the connecting plate are welded to the fixed ring and the connecting plate respectively.

[0015] By adopting the above technical solution, by providing the locking assembly, when the screw rod needs to be rotated, the two connecting plates can move in opposite directions, so that the connecting plates drive the fixing rods to move inside the fixed ring and move out of the inside of the screw rod. When the fixing rods move, the locking tension spring will be stretched, thereby releasing the locking of the screw rod. After the screw rod rotates, under the elastic force of the locking tension spring, the fixing rods can be reset to realize the locking of the screw rod, which can prevent the screw rod from accidentally rotating and losing the positioning function of the closed sleeve.

[0016] The present invention is further configured such that: moving holes and locking grooves for cooperating with the fixing rods are respectively formed on both sides inside the fixed ring and on both sides of the screw rod.

[0017] By adopting the above technical solution, by providing the moving holes and the locking grooves, it is convenient for the fixing rods to move inside the fixed ring, thereby realizing or releasing the locking of the screw rod.

[0018] The present invention is further configured such that: the rotating assembly includes a driving plate, the driving plate is sleeved on the surface of the fitting assembly, fixing columns are bolted to both the front side and the rear side of the top of the driving plate, a movable sleeve is rotatably connected to the surface of the fixing column, a driven rod is welded to the side of the movable sleeve close to the contact assembly, and the side of the driven rod close to the contact assembly is rotatably connected to the contact assembly.

[0019] With the above technical solution, by providing the rotating assembly, when the screw rotates, the driving plate rotates accordingly, and under the action of the fixing column, the movable sleeve and the connecting rod, the two contact assemblies will be driven to move relatively, so that the contact assemblies can be in close contact with the surface of the quartz tube body, thereby achieving the effect of fastening the closed sleeve.

[0020] The present invention is further configured such that: the contact assembly includes a moving plate, an elastic pad is bonded to the side of the moving plate close to the surface of the quartz tube body, a moving rod is bolted to the bottom of the moving plate, a mating plate is bolted to the bottom of the moving rod, a rotating member is rotatably connected to the bottom of the mating plate, and the side of the rotating member close to the driven rod is welded to the driven rod.

[0021] With the above technical solution, by providing the contact assembly, under the action of the rotating member, the mating plate will be driven to move, and the mating plate will drive the moving plate to move through the moving rod, so that the elastic pad is in close contact with the surface of the quartz tube body, thereby restricting the closed sleeve at both ends of the quartz tube body, so that the closed sleeve will not be separated from the quartz tube body due to external force or excessive pressure inside the quartz tube body, thus ensuring the sealing effect of the closed sleeve on the quartz tube body all the time.

[0022] The present invention is further configured such that: the bottom of the rotating member extends into the inside of the closed sleeve and is welded to the driven rod, and movable holes for cooperating with the rotating member are formed on both sides of the bottom of the inner wall of the closed sleeve.

[0023] With the above technical solution, by providing the movable holes, it is convenient for the rotating member to drive the mating plate to move inside the closed sleeve.

[0024] The present invention is further configured such that: a double-tubular structure with an inner tube is provided inside the closed sleeve, and the inner tube structure is in contact with the inner wall of the quartz tube body. The bottom inside the closed sleeve is a cavity structure, and the rotating assembly rotates inside the cavity structure. The rotating member and the driving plate are coaxially arranged.

By providing a cavity structure at the bottom inside the closed sleeve, it is convenient for the rotating assembly to have a moving space.

[0026] In summary, the present invention has the following beneficial effects:

[0027] 1. By providing a positioning mechanism, through the cooperation of the fitting component and the locking component, the closed sleeve can be positioned at both ends of the quartz tube body, and the inner wall of the closed sleeve is in contact with the end face of the quartz tube body, improving the sealing performance of the two ends of the quartz tube body and completing the preliminary closing treatment of the quartz tube body;

[0028] 2. By providing a fastening mechanism, through the cooperation of the rotating component and the contact component, the closed sleeve can be restricted at both ends of the quartz tube body, so that the closed sleeve will not be separated from the quartz tube body due to external force or excessive pressure inside the quartz tube body, thus ensuring the closing effect of the closed sleeve on the quartz tube body all the time.

Detailed implementation manners

[0041] The present invention will be further described in detail below with reference to the accompanying drawings.

[0042] Embodiment 1:

[0043] Refer to Figures 1-7 , a new type of quartz tube structure with both ends closed, including a quartz tube body 1, a closed sleeve 2 and a closing structure 3. The closed sleeves 2 are respectively sleeved on the top and bottom surfaces of the quartz tube body 1. The closing structure 3 includes a positioning mechanism 31. The positioning mechanism 31 includes a fitting assembly 311 and a locking assembly 312. The fitting assembly 311 is rotatably connected inside the closed sleeve 2. The locking assembly 312 is sleeved on the surface of the fitting assembly 311. One side of the locking assembly 312 close to the closed sleeve 2 is bolted to the closed sleeve 2. By providing the closed sleeve 2, due to the double-tubular structure with an inner tube provided inside the closed sleeve 2, the inner tube structure can contact the inner wall of the quartz tube body 1, and the outer tube structure is sleeved on the surface of the quartz tube body 1. And through the setting of the positioning mechanism 31, by the combined use of the fitting assembly 311 and the locking assembly 312, the closed sleeve 2 can be positioned at both ends of the quartz tube body 1, and the inner wall of the closed sleeve 2 is in contact with the end surface of the quartz tube body 1, improving the sealing performance of the two ends of the quartz tube body 1 being closed, and completing the preliminary closing treatment of the quartz tube body 1.

[0044] Such as Figure 4As shown, the fitting assembly 311 includes a screw rod 3111 rotatably connected inside the closed sleeve 2. A limit sleeve 3112 is sleeved on the surface of the screw rod 3111. A nut sleeve 3113 is threadedly connected to the surface of the screw rod 3111. A contact plate 3114 is rotatably connected to the surface of the limit sleeve 3112. The contact plate 3114 is rotatably connected to the nut sleeve 3113. One side of the contact plate 3114 close to the inner wall of the quartz tube body 1 is in close contact with the quartz tube body 1. The screw rod 3111 is used in cooperation with the locking assembly 312. By providing the fitting assembly 311, when the closed sleeve 2 is sleeved on the quartz tube body 1, the screw rod 3111 can rotate inside the closed sleeve 2 and the limit sleeve 3112, so that the nut sleeve 3113 moves on the surface of the screw rod 3111 and pushes the contact plate 3114 to move, so that the contact plate 3114 is adjusted from a retracted state to an open state, and the contact plate 3114 can be brought into contact with the inner wall of the quartz tube body 1. The closed sleeve 2 can be positioned at both ends of the quartz tube body 1, and the inner wall of the closed sleeve 2 is brought into contact with the end face of the quartz tube body 1, improving the sealing performance of the two ends of the quartz tube body 1 being closed, and completing the preliminary closing process of the quartz tube body 1.

[0045] As Figure 7 shown, the contact plate 3114 is annularly rotatably connected to the surface of the limit sleeve 3112. Wedge blocks 4 are provided at both the top and bottom of the inner wall of the quartz tube body 1. A contact part is provided on one side of the contact plate 3114 close to the wedge block 4. The contact part is in close contact with the wedge block 4. By providing the wedge block 4, it is convenient for the contact part on the contact plate 3114 to contact it, so as to facilitate the positioning of the closed sleeve 2 and prevent it from separating from the quartz tube body 1 randomly.

[0046] As Figure 5 shown, connecting frames 5 are annularly bolted to the surfaces of the nut sleeve 3113 and the limit sleeve 3112. A connecting rod 6 is rotatably connected between the opposite sides of the two connecting frames 5. The contact plate 3114 is rotatably connected to the nut sleeve 3113 and the limit sleeve 3112 through the connecting frames 5 and the connecting rod 6. By providing the connecting frames 5 and the connecting rod 6, the contact plate 3114 can be rotatably connected to the nut sleeve 3113 and the limit sleeve 3112, so as to facilitate the nut sleeve 3113 to drive the contact plate 3114 to be adjusted to a retracted or open state.

[0047] As Figure 6As shown, the locking assembly 312 includes a fixing ring 3121 sleeved on the surface of the screw rod 3111. One side of the fixing ring 3121 close to the closed sleeve 2 is bolted to the closed sleeve 2. Fixing rods 3122 penetrate through both sides inside the fixing ring 3121. One side of the fixing rod 3122 close to the screw rod 3111 extends into the inside of the screw rod 3111, and the other side of the fixing rod 3122 away from the screw rod 3111 extends outside the fixing ring 3121 and is bolted with a connecting plate 3123. A locking tension spring 3124 is sleeved on the surface of the fixing rod 3122. One side of the locking tension spring 3124 close to the fixing ring 3121 and the connecting plate 3123 is welded to the fixing ring 3121 and the connecting plate 3123 respectively. By setting the locking assembly 312, when it is necessary to rotate the screw rod 3111, the two connecting plates 3123 can move in opposite directions, so that the connecting plate 3123 drives the fixing rod 3122 to move inside the fixing ring 3121 and move out of the inside of the screw rod 3111. When the fixing rod 3122 moves, it will stretch the locking tension spring 3124, thereby releasing the locking of the screw rod 3111. After the rotation of the screw rod 3111 is completed, under the elastic force of the locking tension spring 3124, the fixing rod 3122 can be reset to realize the locking of the screw rod 3111, which can prevent the loss of the positioning function of the closed sleeve 2 due to the accidental rotation of the screw rod 3111.

[0048] As Figure 6 shown, moving holes 7 and locking grooves 8 that cooperate with the fixing rods 3122 are respectively formed on both sides inside the fixing ring 3121 and both sides of the screw rod 3111. By setting the moving holes 7 and the locking grooves 8, it is convenient for the fixing rods 3122 to move inside the fixing ring 3121, thereby realizing or releasing the locking of the screw rod 3111.

[0049] Brief description of the use process: The encapsulation sleeve is sleeved on the top and bottom of the surface of the quartz tube body 1. Then, the two connecting plates 3123 move in opposite directions, so that the connecting plate 3123 drives the fixing rod 3122 to move inside the fixing ring 3121 and move out of the inside of the screw rod 3111. When the fixing rod 3122 moves, it will stretch the locking tension spring 3124, thereby releasing the locking of the screw rod 3111. Then, by rotating the screw rod 3111 inside the closed sleeve 2 and the limit sleeve 3112, the screw sleeve 3113 moves on the surface of the screw rod 3111, and the contact plate 3114 is pushed to move by the connecting rod 6, so that the contact plate 3114 is adjusted from the retracted state to the open state, and the contact plate 3114 can contact the wedge block 4 on the inner wall of the quartz tube body 1, and the closed sleeve 2 can be positioned at both ends of the quartz tube body 1, and the inner wall of the closed sleeve 2 contacts the end face of the quartz tube body 1. Finally, under the elastic force of the locking tension spring 3124, the fixing rod 3122 can be reset to realize the locking of the screw rod 3111.

[0050] Embodiment 2:

[0051] Reference Figures 8-11 , the closed structure 3 includes a fastening mechanism 32. The fastening mechanism 32 includes a rotating assembly 321. The rotating assembly 321 is sleeved on the surface of the fitting assembly 311. One end of the rotating assembly 321 is rotatably connected to a contact assembly 322. One side of the contact assembly 322 close to the surface of the quartz tube body 1 is in close contact with the quartz tube body 1. Through the setting of the fastening mechanism 32 and the combined use of the rotating assembly 321 and the contact assembly 322, the closed sleeve 2 can be restricted at both ends of the quartz tube body 1, so that the closed sleeve 2 will not be separated from the quartz tube body 1 due to external force or excessive pressure inside the quartz tube body 1, thus ensuring that the closed sleeve 2 always has a sealing effect on the quartz tube body 1.

[0052] As Figure 10 shown, the rotating assembly 321 includes a driving plate 3211. The driving plate 3211 is sleeved on the surface of the fitting assembly 311. Fixed columns 3212 are bolted to the front side and the rear side of the top of the driving plate 3211. An activity sleeve 3213 is rotatably connected to the surface of the fixed column 3212. A driven rod 3214 is welded to one side of the activity sleeve 3213 close to the contact assembly 322. One side of the driven rod 3214 close to the contact assembly 322 is rotatably connected to the contact assembly 322. By setting the rotating assembly 321, when the screw 3111 rotates, the driving plate 3211 rotates accordingly. Under the action of the fixed column 3212, the activity sleeve 3213 and the connecting rod 6, the two contact assemblies 322 will be driven to move relatively, so that the contact assembly 322 can be in close contact with the surface of the quartz tube body 1, thereby realizing the effect of fastening the closed sleeve 2.

[0053] As Figure 11 shown, the contact assembly 322 includes a moving plate 3221. An elastic pad 3222 is bonded to one side of the moving plate 3221 close to the surface of the quartz tube body 1. A moving rod 3223 is bolted to the bottom of the moving plate 3221. The bottom of the moving rod 3223 is bolted to a matching plate 3224. A rotating part 3225 is rotatably connected to the bottom of the matching plate 3224. One side of the rotating part 3225 close to the driven rod 3214 is welded to the driven rod 3214. By setting the contact assembly 322, under the action of the rotating part 3225, the matching plate 3224 will be driven to move. The matching plate 3224 will drive the moving plate 3221 to move through the moving rod 3223, so that the elastic pad 3222 is in close contact with the surface of the quartz tube body 1, thereby restricting the closed sleeve 2 at both ends of the quartz tube body 1, so that the closed sleeve 2 will not be separated from the quartz tube body 1 due to external force or excessive pressure inside the quartz tube body 1, thus ensuring that the closed sleeve 2 always has a sealing effect on the quartz tube body 1.

[0054] As Figure 8As shown, the bottom of the rotating member 3225 extends into the interior of the closed sleeve 2 and is welded to the driven rod 3214. Activity holes 9 that cooperate with the rotating member 3225 are formed on both sides of the bottom of the inner wall of the closed sleeve 2. By providing the activity holes 9, it is convenient for the rotating member 3225 to drive the cooperation plate 3224 to move inside the closed sleeve 2.

[0055] As Figure 8 shown, the closed sleeve 2 has a double-tubular structure with an inner tube inside, and the inner tube structure contacts the inner wall of the quartz tube body 1. The bottom inside the closed sleeve 2 is a cavity structure, and the rotating assembly 321 rotates within the cavity structure. The rotating member 3225 and the active plate 3211 are coaxially arranged. By providing the double-tubular structure with an inner tube inside the closed sleeve 2, the inner tube structure can contact the inner wall of the quartz tube body 1, while the outer tube structure is sleeved on the surface of the quartz tube body 1, improving the sealing effect. By having a cavity structure at the bottom inside the closed sleeve 2, it is convenient for the rotating assembly 321 to have a movement space.

[0056] Brief description of the usage process: When the screw 3111 rotates, the active plate 3211 rotates accordingly. Under the action of the fixed column 3212, the movable sleeve 3213, and the connecting rod 6, the rotating member 3225 swings and moves within the activity hole 9, driving the two cooperation plates 3224 to move. The cooperation plate 3224 drives the movable plate 3221 to move through the moving rod 3223, making the elastic pad 3222 closely contact the surface of the quartz tube body 1, thereby restricting the closed sleeve 2 at both ends of the quartz tube body 1, so that the closed sleeve 2 will not separate from the quartz tube body 1 due to external force or excessive pressure inside the quartz tube body 1.
