Description

Technical Field

[0001] This invention belongs to the field of transmission device technology, specifically relating to a ring transmission device for a hydraulic tensioner of an electric vehicle engine. Background Technology

[0002] The hydraulic tensioner is a crucial component of the engine timing system. Its primary function is to guide and tension the timing belt or chain, ensuring they are always at optimal tension. The hydraulic tensioner operates based on a combination of hydraulic pressure and mechanical mechanisms. When the engine is running, hydraulic oil supplied by the pump enters the tensioner's oil chamber, pushing a piston or similar element outward, thereby tensioning the timing belt or chain.

[0003] The prior art CN118912166A discloses a ring transmission device for a hydraulic tensioner of an automobile engine, including a bracket. A lower L-shaped plate is fixedly connected to the lower side of one side of the bracket. An upper L-shaped plate is arranged above the lower L-shaped plate. A lower connecting seat is slidably connected to the upper surface of the lower L-shaped plate along both sides. An upper connecting seat is slidably connected to the lower surface of the upper L-shaped plate along both sides. Lateral elastic mechanisms are respectively arranged between the lower L-shaped plate and the lower connecting seat, and between the upper L-shaped plate and the upper connecting seat. A telescopic cylinder is installed between the upper and lower connecting seats. A guide plate is connected to the upper end of one side surface of the lower L-shaped plate through a vertical elastic mechanism. A guide cylinder is fixedly connected to one side surface of the upper L-shaped plate. The upper end of the guide plate is slidably inserted into the inner side of the guide cylinder. A lifting plate is fixedly connected to the upper surface of the upper L-shaped plate. A driven wheel mechanism is arranged behind the lifting plate. A power shaft is rotatably mounted on the side of the bracket away from the lower L-shaped plate. The surface of the power shaft and the driven wheel mechanism are driven by a synchronous belt. The vibration damping structure of the transmission device is located on one side of the transmission device. This layout leads to a lack of stability during vibration damping. Furthermore, the telescopic cylinder and the upper bracket are assembled using threaded connections. Frequent vibrations can cause the connected parts to disintegrate, making it impossible to guarantee the normal use of the device and shortening the maintenance cycle. Summary of the Invention

[0004] This invention provides a ring transmission device for a hydraulic tensioner of an electric vehicle engine. The purpose is to solve the problem that the vibration damping structure of the existing ring transmission device for a hydraulic tensioner of an electric vehicle engine is set on one side of the transmission device. This layout leads to a lack of stability during vibration damping. In addition, the telescopic cylinder and the upper bracket are assembled by threaded connection. Frequent vibration will cause the connected parts to disintegrate, which cannot guarantee the normal use of the device and shortens the maintenance cycle of the device.

[0005] This invention provides a ring transmission device for a hydraulic tensioner of an electric vehicle engine, comprising a lower bracket, an upper bracket movably connected to the upper end of the lower bracket, an upper support platform and a lower support platform mounted on the inner side of the lower bracket, a pair of vertical plates on the upper end of the upper support platform slidingly passing through the lower bracket and fixedly connected to a pair of horizontal plates of the upper bracket, a connecting seat being laterally slidably fastened to the lower end of the upper support platform and the upper end of the lower support platform, a telescopic cylinder being installed between the pair of connecting seats, two pairs of waist-shaped adjustment holes being reserved on the two sides of the lower bracket, a connecting rod being installed between each pair of waist-shaped adjustment holes, a driven shaft being screwed onto the upper bracket, a power shaft being screwed onto one side of the lower bracket, the driven shaft and the power shaft being connected via a synchronous belt drive, the connecting seat and the telescopic cylinder and the connecting rod and the upper bracket being connected via connecting parts, the two sides of the connecting seat being connected to the inner side of the lower bracket via lateral vibration damping, the upper side of the lateral vibration damping being slidably fastened to the inner side wall of the lower bracket, and a longitudinal vibration damping module being installed between the two sides of the telescopic cylinder and the upper bracket.

[0006] Furthermore, the connector includes a fitting and a connecting post installed inside the fitting, the side of the connecting post away from the fitting being fixedly connected to the corresponding telescopic cylinder and connecting rod, and also includes:

[0007] The connecting module and the connector are fitted together on one side.

[0008] A rotating unit is installed in the fitting joint and is fitted with two pairs of locking units that are circumferentially spaced in the fitting joint.

[0009] The constraint unit is mirror-installed on both sides inside the connector. After the constraint unit is moved, it constrains the position of the connecting module.

[0010] Reinforcing unit A is installed inside the connector on the side farther from the connecting module.

[0011] Reinforcing unit B, there are two pairs of reinforcing units B, which are installed in the fitting joint at equal intervals in a circumferential direction;

[0012] Among them, the rotating unit includes a rotating tube, and a pair of skewed openings A and a pair of skewed openings B are reserved on the outer surface of the rotating tube. The pair of skewed openings A are spaced apart by half a circumference, the pair of skewed openings B are spaced apart by half a circumference, and two pairs of skewed openings C are reserved circumferentially on the outer surface of the rotating tube.

[0013] The constraint unit includes a constraint plate and a blocking platform fixed to one side of the constraint plate. A pair of rectangular openings A and a pair of arched openings are reserved on the inner surface of the connector. The pair of rectangular openings A are spaced apart by half a circumference, and the pair of arched openings are spaced apart by half a circumference.

[0014] The locking unit includes a tilting platform A and a tilting platform B that is fitted and connected to the tilting platform A. One side of the tilting platform B is fixedly connected to an arched piece.

[0015] Reinforcing unit A includes two pairs of variable chambers and variable columns circumferentially spaced in the fitting joint. A silicone bag is installed in the fitting joint. Reinforcing unit B includes a meshing platform. Two pairs of guide ports are circumferentially spaced from one side of reinforcing unit A by the rotating tube.

[0016] The skewed openings A and C are set in opposite directions to each other. The outer surface of the fitting is threaded with a threaded tube. A column B is movably installed in the skewed opening B. The opposite sides of a pair of columns B are fixed to a constraint platform.

[0017] The threaded tube has a groove reserved for applying lateral constraints to the constraint platform. The side of the constraint platform that is farther from the column B can be movably installed in the threaded tube. The fitting has a rectangular opening B reserved for applying circumferential constraints to the constraint platform.

[0018] When the threaded tube rotates, the traction constraint platform and column B move towards the side farther from the connecting module. When column B moves, it moves along the direction of the skewed opening B, and the traction rotating tube performs rotation.

[0019] Furthermore, the connecting module includes an insert and a tooth fixed to the outer peripheral surface of the insert. A flange is provided on the outer peripheral surface of the insert on the side farther from the connecting post. The flange is in contact with the outer wall surface of the corresponding connecting seat and the outer wall surface of the upper bracket. A pair of posts A are fixed to the outer peripheral surface of the insert. The pair of posts A are spaced half a circumference apart from each other. Initially, posts A can be moved and inserted into the rectangular opening A.

[0020] Furthermore, a column C is fixedly connected to one of the walls on which a pair of constraint plates face each other. The column C is movably installed in the skewed opening A. The rectangular opening A and the arched opening are connected on their opposite sides, and the barrier platform is located in the arched opening.

[0021] Furthermore, a column D is fixedly connected to the wall on the opposite side of a pair of tilted platforms A. The column D is movably installed in the tilted opening C. The sides of tilted platforms A and B that are directly opposite each other are tilted. The side of the arched piece that is farther away from tilted platform B is fixedly connected to a stop block.

[0022] One side wall of the stop block can be fitted into the notch on the circumference of the connecting column. The stop block is initially separated from the surface of the connecting column. The side of the arched piece farther from the stop block is fixed with a wavy beryllium copper strip. The arched piece is connected to the fitting joint via the beryllium copper strip.

[0023] Furthermore, a silicone platform is movably installed in the variable chamber, and a variable column is fixedly connected to the silicone platform. The side of the variable column that is farther away from the silicone platform is fixedly connected to the tilting platform A. A through opening for connecting to the silicone bag is reserved on one side of the variable chamber.

[0024] The engagement platform is initially housed in the interlocking joint. The column E is fixedly connected to the center of the engagement platform. An engagement opening is reserved on the inner side of the engagement platform. The column E can be movably installed in the guide opening. A constraint channel for applying lateral constraints to the column E is reserved on the inner wall of the interlocking joint.

[0025] Furthermore, the longitudinal vibration damping module includes two pairs of fixed plates fixed to the two sides of the inner side of the lower support. Two sets of longitudinal vibration damping dampers are fixed to the wall surface opposite each pair of fixed plates. An inner support is fixed between the two sets of longitudinal vibration damping dampers. The two vertical plates of the inner support slide through the lower support and are fixed to the upper support.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. The present invention, through the symmetrical installation of transverse damping and longitudinal damping modules, makes the damping structure of the entire device symmetrically arranged, ensuring the stability of the device during damping, and through the installation of connecting parts, ensuring the stability of the connection during vibration, avoiding the disintegration of parts, and greatly extending the maintenance cycle of the device.

[0028] 2. Through the installation of the connector, the user moves the column A into the rectangular opening A, and then pulls the column A along the direction of the rectangular opening A to insert the connector into the connector. Then the column A and the rectangular opening A are in contact. At this time, by rotating the connector, the column A is moved into the arched opening until the column A and the inner wall of the arched opening are in contact. The user inserts the connector into the side of the connector that is farther away from the connector module.

[0029] Next, the threaded tube is rotated, and then the threaded tube moves towards the reinforcing unit A along the thread direction on the connector. During the rotation of the threaded tube, the constraint platform is laterally constrained through the groove on its inner wall. Then, while the constraint platform moves in the threaded tube, it pulls the column B to move towards the reinforcing unit A. Then, the column B moves along the direction of the skewed opening B, and pulls the rotating tube to rotate. During the rotation of the rotating tube, the column C moves along the direction of the skewed opening A, and pulls the constraint plate towards the connecting module. The column D moves along the direction of the skewed opening C, and pulls the skewed platform A towards the reinforcing unit A. Then, the constraint plate pulls the barrier platform to move inward into the arched opening. After the change, the barrier platform constrains the column A, which is movably installed in the arched opening, so that the column A cannot rotate or move. Then, the connecting module is fastened in the connector.

[0030] During the movement of the inclined platform A towards the reinforcing unit A, it applies pressure to the tightly pressed inclined platform B, which in turn causes the inclined platform B to pull the arched piece and the stop block on one side towards the connecting column. When the horizontal walls of the inclined platform A and the inclined platform B are in contact, both pairs of stop blocks press against the notches on the wall of the connecting column and apply pressure to the inner wall of the notches on the connecting column. The two pairs of stop blocks apply pressure and tighten the connecting column to prevent the connecting column from moving and to tighten the connecting column.

[0031] During the movement of the tilting platform A, the tilting column fixed to one side of the tilting platform A is also pulled to move inward into the tilting chamber. Then, the silicone platform on the tilting column compresses the gas in the tilting chamber, and the compressed gas moves through the through-hole into the silicone bag. Then, when the inner wall of the column D and the tilting port C are in contact, the gas in both pairs of tilting chambers is compressed into the silicone bag, which then expands and presses against the wall of the connecting column. The deformation of the silicone bag itself further tightens the connecting column, thus preventing the connecting column from disintegrating under vibration. The expanded silicone bag can also fill the gap between the connecting column and the fitting, ensuring the reliability of the connection, and also preventing moisture from flowing into the fitting and causing corrosion damage to the internal components.

[0032] During the rotation of the rotating tube, the column E is also pulled to move along the direction of the guide port. At this time, due to the circumferential constraint of the constraint channel on the column E, the column E can only be pulled to move towards one side of the connecting module when it moves. After the two pairs of engagement tables move, their engagement mouths are engaged with the corresponding teeth, which strengthens the fastening of the interlocking part and makes the assembly between it and the interlocking part more secure. This prevents the interlocking part from disintegrating from the interlocking part under vibration, thereby achieving the purpose of fastening.

Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0048] Reference Figure 1 This invention provides a ring transmission device for a hydraulic tensioner of an electric vehicle engine, comprising a lower support 1, an upper support 2 movably connected to the upper end of the lower support 1, an upper support platform 3 and a lower support platform 4 mounted on the inner side of the lower support 1, the upper support platform 3 being above the lower support platform 4, a pair of vertical plates at the upper end of the upper support platform 3 slidingly passing through the lower support 1 and fixedly connected to a pair of horizontal plates of the upper support 2, the two lateral sides of the lower support platform 4 being fixedly connected to the inner side of the lower support 1, the lower end of the upper support platform 3 and the upper end of the lower support platform 4 being laterally slidably connected to connecting seats 5, a telescopic cylinder 6 being installed between a pair of connecting seats 5, and two pairs of waist-shaped adjustment holes 7 being reserved on the two lateral sides of the lower support 1, with a connecting rod 8 installed between each pair of waist-shaped adjustment holes 7. The driven shaft 12 is screwed onto the upper bracket 2, and the power shaft 13 is screwed onto one side of the lower bracket 1. The driven shaft 12 and the power shaft 13 are connected by a synchronous belt 14. The connecting seat 5 and the telescopic cylinder 6, as well as the connecting rod 8 and the upper bracket 2, are connected by a connecting piece 9. The connecting piece 9 is movably connected to the corresponding connecting seat 5, the waist-shaped adjustment hole 7, and the upper bracket 2. The two lateral sides of the connecting seat 5 are connected to the inner side of the lower bracket 1 by a lateral damping damper 10. The upper lateral damping damper 10 is slidably fastened to the inner wall of the lower bracket 1 to ensure that the lateral damping damper 10 will not cause obstruction when the telescopic cylinder 6 adjusts the tension. The longitudinal damping module 11 is installed between the two lateral sides of the telescopic cylinder 6 and the upper bracket 2.

[0049] By symmetrically installing the transverse damping damper 10 and the longitudinal damping module 11, the damping structure of the entire device is symmetrically arranged, ensuring the stability of the device during damping. Furthermore, the installation of the connector 9 ensures the stability of the connection during vibration, preventing disintegration between parts and greatly extending the maintenance cycle of the device.

[0050] Reference Figures 2-11 The connector 9 includes a fitting 91 and a connecting post 98 installed inside the fitting 91. The side of the connecting post 98 away from the fitting 91 is fixedly connected to the corresponding telescopic cylinder 6 and connecting rod 8. It also includes:

[0051] Connecting module 92, connecting module 92 and fitting connector 91 are fitted together on one side;

[0052] Rotating unit 93 is installed in the fitting joint 91 and is fitted with two pairs of locking units 95 that are circumferentially spaced in the fitting joint 91.

[0053] Constraint unit 94 is mirror-installed on both sides inside the connector 91. After the constraint unit 94 is moved, it constrains the position of the connecting module 92.

[0054] Reinforcing unit A96 is assembled inside the insert 91 on the side farther from the connecting module 92;

[0055] The reinforcing unit B97 is provided in two pairs, and the two pairs of reinforcing units B97 are circumferentially and equally spaced in the fitting joint 91.

[0056] Among them, the rotating unit 93 includes a rotating tube 931. A pair of skewed openings A932 and a pair of skewed openings B933 are reserved on the outer surface of the rotating tube 931. The pair of skewed openings A932 are spaced apart by half a circumference, and the pair of skewed openings B933 are spaced apart by half a circumference. Two pairs of skewed openings C934 are reserved circumferentially on the outer surface of the rotating tube 931.

[0057] The constraint unit 94 includes a constraint piece 941 and a blocking platform 943 fixed to one side of the constraint piece 941. A pair of rectangular openings A944 and a pair of arched openings 945 are reserved on the inner surface of the connector 91. The pair of rectangular openings A944 are spaced apart by half a circumference, and the pair of arched openings 945 are spaced apart by half a circumference.

[0058] The locking unit 95 includes a tilting platform A951 and a tilting platform B955 that is fitted and connected to the tilting platform A951. One side of the tilting platform B955 is fixedly connected to the arched piece 953.

[0059] The reinforcing unit A96 includes two pairs of variable chambers 961 and variable columns 962 that are circumferentially and equally spaced in the fitting 91. A silicone bag 964 is installed in the fitting 91. The reinforcing unit B97 includes a meshing table 971. The rotating tube 931 has two pairs of guide ports 973 that are circumferentially and equally spaced from one side of the reinforcing unit A96.

[0060] The skewed openings A932 and C934 are arranged in opposite directions to each other. The outer surface of the fitting 91 is threaded to the threaded tube 935. The column B937 is movably installed in the skewed opening B933. The opposite sides of the pair of columns B937 are fixed to the constraint table 936.

[0061] The threaded tube 935 has a groove reserved for performing lateral constraints on the constraint platform 936. The side of the constraint platform 936 that is farther away from the column B937 can be movably installed in the threaded tube 935. The fitting 91 has a rectangular opening B reserved for performing circumferential constraints on the constraint platform 936.

[0062] When the threaded tube 935 rotates, the traction constraint table 936 and the column B937 move toward the side farther from the connecting module 92. When the column B937 moves, it moves along the direction of the skewed opening B933, and the traction rotating tube 931 rotates.

[0063] With the inclined port A932 and inclined port C934 arranged in opposite directions, when the rotating tube 931 rotates, it can pull the constraint plate 941 and the inclined platform A951 to perform reverse movement. The inside of the threaded tube 935 is reserved with a groove for performing lateral constraint on the constraint platform 936. Then, when the threaded tube 935 rotates, the side of the constraint platform 936 that is farther away from the column B937 can perform circumferential movement inside the groove, which makes it easy to use.

[0064] After the rotating tube 931 rotates, it causes the constraint piece 941 in the fitting 91 and the tilting platform A951 to move. After the constraint piece 941 moves, the traction blocking platform 943 is inserted into the arched opening 945, which then constrains the connecting module 92 inside the arched opening 945, and stops the connecting module 92. Then, the tilting platform A951 moves and presses the tilting platform B955, which is closely attached to it, towards the connecting post 98, which then pulls the arched piece 953 to move in one place. After the two pairs of arched pieces 953 move, they constrain the outer surface of the connecting post 98, and then perform... The stop position is then used to synchronously stop the connection module 92 and the connection post 98. After the change of the change post 962, the gas in the change chamber 961 is compressed into the silicone bag 964, which then expands and stops the connection post 98 again through its own deformation. Furthermore, the rotation of the rotating tube 931 also pulls the engagement table 971 to move towards one side of the connection module 92, so that both pairs of engagement tables 971 are embedded in the connection module 92, and then stops the connection module 92 again, thereby preventing the connection module 92 and the connection post 98 from disintegrating due to vibration during operation.

[0065] Reference Figure 3 , Figure 4 , Figure 8 and Figure 10The connecting module 92 includes a fitting part 921 and a tooth 923 fixed to the outer peripheral surface of the fitting part 921. A flange is provided on the outer peripheral surface of the fitting part 921 on the side farther from the connecting post 98. The flange is in contact with the outer wall surface of the corresponding connecting seat 5 and the outer wall surface of the upper bracket 2. A pair of columns A922 are fixed to the outer peripheral surface of the fitting part 921. The pair of columns A922 are spaced half a circumference apart. The columns A922 are initially movable and fitted into the rectangular opening A944. A pair of constraint plates 941 are fixed to the wall surface facing each other. The columns C942 are movable and installed in the skewed opening A932. The rectangular opening A944 and the arched opening 945 are connected on the side facing each other. The blocking platform 943 is located in the arched opening 945.

[0066] With the rectangular opening A944 and the arched opening 945 installed, only after the column A922 is successfully moved into the rectangular opening A944 can the entire insert 921 be pulled into the insert 91, thereby avoiding misconnection. Furthermore, the rectangular opening A944 and the arched opening 945 are connected to each other, which facilitates the successful movement of the column A922 into the arched opening 945, and the arched opening 945 applies lateral constraints to the connecting module 92.

[0067] Reference Figure 3 , Figure 4 and Figure 6 A pair of tilting platforms A951 are fixedly connected to a column D952 on the opposite side of the wall. The column D952 is movably installed in the tilting opening C934. The tilting platforms A951 and B955 are tilted on opposite sides. The side of the arched piece 953 farthest from the tilting platform B955 is fixedly connected to a stop block 954. One side wall of the stop block 954 can be inserted into a recess on the circumference of the connecting column 98. The stop block 954 is initially separated from the surface of the connecting column 98. The side of the arched piece 953 farthest from the stop block 954 is fixedly connected to a wavy beryllium copper strip 956. The arched piece 953 is connected to the fitting joint 91 via the beryllium copper strip 956.

[0068] By installing the stop block 954, it can be pressed against the connecting post 98, thereby evenly tightening the connecting post 98, thus enhancing the stability and firmness of the tightening. Since the stop block 954 is initially separated from the wall surface of the connecting post 98, it prevents the stop block 954 from first adhering to the wall surface of the connecting post 98, thus ensuring that the connecting post 98 can be successfully inserted into the fitting 91.

[0069] With the installation of the beryllium copper strip 956, when the tilting platform A951 releases its pressure on the tilting platform B955, the arched piece 953, with the cooperation of the beryllium copper strip 956, pulls the tilting platform B955 and the stop block 954 back to their original positions, making it easier to reuse. It can also pull the stop block 954 to release its pressure on the notch on the connecting post 98, so that the connecting post 98 can be moved away.

[0070] Reference Figure 3 , Figure 4 and Figure 6 A silicone platform is movably installed in the variable chamber 961. A variable column 962 is fixedly connected to the silicone platform. The side of the variable column 962 that is farther away from the silicone platform is fixedly connected to the tilting platform A951. A through port 963 is reserved on one side of the variable chamber 961 to connect with the silicone bag 964. The biting table 971 is initially stored in the fitting joint 91. The column E972 is fixedly connected to the center of the biting table 971. A biting opening is reserved on the inner side of the biting table 971. The column E972 is movably installed in the guide port 973. A constraint channel 974 is reserved on the inner wall of the fitting joint 91 for performing lateral constraint on the column E972.

[0071] The gas in the variable chamber 961 is compressed into the silicone bag 964 through the through port 963, thereby causing the silicone bag 964 to expand. The deformation of the silicone bag 964 then stops the connecting post 98. The expanded silicone bag 964 can also fill the gap between the peripheral wall of the connecting post 98 and the inner wall of the fitting 91, ensuring the reliability of the connection and preventing moisture from flowing into the fitting 91 and causing corrosion and damage to the internal components.

[0072] In use, the user moves the column A922 into the rectangular opening A944, and then pulls the insert part 921 into the insert joint 91 along the direction of the rectangular opening A944. Then the column A922 and the rectangular opening A944 come into contact. At this time, by rotating the insert part 921, the column A922 is moved into the arched opening 945 until the inner wall of the column A922 and the arched opening 945 come into contact. The user then inserts the connecting post 98 into the inside of the insert joint 91 on the side farther from the connecting module 92.

[0073] Next, by rotating the threaded tube 935, the threaded tube 935 moves towards the reinforcing unit A96 along the thread direction on the fitting 91. During the rotation of the threaded tube 935, the constraint table 936 is laterally constrained through the grooves on its inner wall. Then, while the constraint table 936 moves within the threaded tube 935, the traction column B937 also moves towards the reinforcing unit A96. The column B937 then moves along the direction of the inclined opening B933, and the traction rotating tube 931 rotates. During the rotation of the rotating tube 931, the column B937... 942 pulls the constraint piece 941 along the direction of the skewed opening A932 towards one side of the connecting module 92. The column D952 pulls the skewed platform A951 along the direction of the skewed opening C934 towards one side of the reinforcing unit A96. Then, the constraint piece 941 pulls the blocking platform 943 towards the inside of the arched opening 945. After the change, the blocking platform 943 constrains the column A922, which is movably installed in the arched opening 945, so that the column A922 cannot rotate or move. Then, the connecting module 92 is fastened in the connector 91.

[0074] During the movement of the inclined platform A951 toward the reinforcing unit A96, it applies pressure to the tightly pressed inclined platform B955, which in turn causes the inclined platform B955 to pull the arched piece 953 and the stop block 954 on one side toward the connecting column 98. When the horizontal walls of the inclined platform A951 and the inclined platform B955 are in contact, both pairs of stop blocks 954 press against the recesses on the wall of the connecting column 98 and apply pressure to the inner wall of the recesses on the connecting column 98. The two pairs of stop blocks 954 apply pressure and tighten the connecting column 98 to prevent the connecting column 98 from moving and to tighten the connecting column 98.

[0075] During the movement of the tilting platform A951, the tilting column 962, which is fixed to one side of the tilting platform A951, is also pulled to move inward toward the inside of the tilting chamber 961. Then, the silicone platform on the tilting column 962 compresses the gas in the tilting chamber 961. The compressed gas then moves through the through-hole 963 into the silicone bag 964. Then, when the inner wall of the column D952 and the tilting port C934 are in contact, the gas in both pairs of tilting chambers 961 is compressed into the silicone bag 964. The silicone bag 964 then expands and presses against the wall of the connecting column 98. The deformation of the silicone bag 964 itself further tightens the connecting column 98, thus preventing the connecting column 98 from disintegrating under vibration. The expanded silicone bag 964 can also fill the gap between the connecting column 98 and the fitting 91, ensuring the reliability of the connection and preventing moisture from flowing into the fitting 91 and causing corrosion damage to the internal components.

[0076] During the rotation of the rotating tube 931, the column E972 is also pulled to move along the direction of the guide port 973. At this time, due to the circumferential constraint of the constraint channel 974 on the column E972, the column E972 can only pull the biting table 971 to move towards one side of the connecting module 92 when it moves. After the two pairs of biting tables 971 move, their biting mouths are engaged with the corresponding teeth 923, which strengthens the fastening of the insert 921 and makes the assembly between it and the insert 91 more secure, so as to prevent the insert 921 from disintegrating from the insert 91 under vibration, thereby achieving the purpose of fastening.

[0077] Reference Figure 1 The longitudinal vibration damping module 11 includes two pairs of fixed plates 111 fixed to the two sides of the inner side of the lower support 1. Two sets of longitudinal vibration damping dampers 113 are fixed to the wall surface opposite each pair of fixed plates 111. An inner support 112 is fixed between the two sets of longitudinal vibration damping dampers 113. The two vertical plates of the inner support 112 slide through the lower support 1 and are fixed to the upper support 2.

[0078] Through the cooperation of longitudinal damping 113 and inner support 112, the vertical vibration is smoothly reduced, ensuring the stable operation of the device.
