Description

Technical Field

[0001] The invention belongs to the technical field of spraying equipment, and more specifically, particularly relates to a spraying equipment for steel pipes of fitness equipment. Background Art

[0002] Modern people pay more and more attention to physical health, and the society has an increasing demand for fitness equipment. Fitness equipment will be manufactured into various shapes suitable for sports. A large number of steel pipes will be used in the structure of fitness equipment. The steel pipes will be bent into different shapes, and then steel pipes of different shapes will be welded together and spliced ​​into the required structure.

[0003] 1. Fitness equipment is usually composed of steel pipes of various shapes and sizes that are cleverly combined and installed. When used, the steel pipes will gradually wear out due to frequent friction and contact, causing the protective paint originally coated on the surface of the steel pipe to gradually peel off. When the protective paint on the surface of the steel pipe falls off, the staff needs to remove the involved steel pipe connectors one by one. Removing the relevant connecting parts one by one consumes a lot of time, and also causes the fitness equipment to be idle for a long time.

[0004] 2. The steel tubes of fitness equipment are of different types, such as round tubes, square tubes, and oval tubes. Multiple different types of steel tubes will be used on the same fitness equipment. There is no universal clamp when clamping and spraying the steel tubes. To fix different types of steel tubes, tools need to be replaced, which will extend the spraying time. Summary of the invention

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] In the present invention, the protective paint is introduced into the interior of the connecting pipe through the pipeline connecting joint, and the protective paint solution is pushed to flow inside the connecting pipe into the interior of the fixing ring by using the high-pressure airflow, and is sprayed out through multiple nozzles to spray the surface of the steel pipe. At the same time, the steel pipe is clamped by two mounting shells and sprayed by the internal nozzle. There is no need to disassemble the fitness equipment, the operation is more convenient, and the idle time of the fitness equipment is also reduced.

[0011] In the present invention, by rotating the rotating buckle in the opposite direction, the rotating buckle drives the transmission rod to rotate in the opposite direction of the first fixed box, and the end of the second pull rod rotates counterclockwise inside the second connecting block, and the counterclockwise rotating third pull rod deflects to the side of the first clamping plate, and the third pull rod applies a thrust to the guide slider. Due to the different lengths and deflection angles of the first rotating rod and the second rotating rod, and the first push plate and the second push plate are at different horizontal positions inside the second clamping plate and the first clamping plate, the second clamping plate and the first clamping plate are squeezed respectively, so that the second clamping plate and the first clamping plate are rotated and deflected in sections, and can be clamped and fixed by square tubes, round tubes or elliptical tubes, thereby increasing the versatility of the equipment.

[0012] In the present invention, by pushing the second fixing box, the second fixing box drives the two first fixing boxes to slide inside the first guide plate, and the two second fixing boxes respectively enter the interior of the mounting shell along the first guide plate, driving the two bases to be respectively extruded toward the surface of the steel pipe, and by fitting the two bases and the inner sides of the arc blocks with the surface of the steel pipe and fixing them, since the two different bases and the arc blocks move and extrude in two symmetrical directions respectively, the steel pipe is subjected to a bidirectional force, and thrust is applied to the two bases and the arc blocks in opposite directions, so that the two bases and the arc blocks can clamp the steel pipe while fixing steel pipes of different diameters.

[0013] In the present invention, the rotating buckle is rotated to rotate on the outside of the second fixed box, and a bevel gear is installed at the end of the rotating buckle to connect with two transmission rods, so that the transmission rod drives the threaded rod to rotate. Through the rotation of the threaded rod, a thrust is applied to the threaded rod, so that the threaded rod slides directionally inside the first fixed box. The movement of the threaded rod pushes the two second pull rods to deflect at the bottom end of the threaded rod, and the base surface of the base and the arc block is expanded by pushing the two arc blocks to slide on the side ends of the base. At the same time, the angle of the arc block is adjusted, and the arc block drives the first clamping plate and the second clamping plate to deflect, thereby increasing the force area.

[0027] A second push plate 51 is slidably mounted inside each first clamping plate 23, a second rotating rod 52 is rotatably mounted on the top of each second push plate 51, a second connecting block 55 is fixedly mounted inside each arc block 22, a third pull rod 54 is fixedly mounted on both side ends of each second pull rod 45, two mounting grooves 27 are provided on the outside of each mounting shell 11, a limited slider 28 is slidably mounted on the inner side wall of each mounting groove 27, a spring rod 29 is fixedly mounted on the side end of each limited slider 28, and a third pull rod 54 is fixedly mounted on the top of each mounting shell 11. Two first card seats 17 are installed, and a fixing plate 18 is rotatably installed inside each first card seat 17. Second guide plates 33 are fixedly installed on the two side ends of each first fixing box 13. By moving the two mounting shells 11, the two mounting shells 11 are aligned with each other, and the two ends of the mounting shells 11 are symmetrically fitted. The steel pipe is first wrapped by the two mounting shells 11, and the two fixing plates 18 are rotated to rotate inside the first card seat 17. The fixing plate 18 deflects to one side and enters the inside of the mounting groove 27. The bottom end of the inner wall is provided with an arc-shaped groove, which is aligned with the side end of the fixing plate 18. The fixing plate 18 rotates into the inside of the installation groove 27 and maintains a horizontal state. By releasing the pulling force on the limit slider 28, under the reverse force of the spring rod 29, the spring rod 29 applies a thrust to the limit slider 28, so that the limit slider 28 moves toward the fixing plate 18 inside the installation groove 27. The top of the fixing plate 18 is provided with a groove, and one side of the limit slider 28 is a convex design. The limit slider 28 moves to dock with the side end of the fixing plate 18. First, the two mounting shells 11 are inserted The assembled installation is carried out in rows, two positioning rods 35 are slidably installed inside each second guide plate 33, and the side ends of the two positioning rods 35 are fixedly installed with the first connecting blocks 34, and a rotating buckle 38 is rotatably installed on the outer side of each second fixed box 14, and a connecting shaft 36 is slidably installed at the end of each rotating buckle 38, and a ring 39 is rotatably installed on the surface of each rotating buckle 38, and a first pull rod 41 is rotatably installed on both sides of each ring 39. The first pull rod 41 is a T-shaped design, and the ends of the first pull rod 41 are rotatably connected to the two first connecting blocks 34.

[0028] Working principle:

[0029] In the first step, the two mounting shells 11 are moved to align the two mounting shells 11 with each other, and the two ends of the mounting shells 11 are symmetrically fitted. The steel pipe is first wrapped by the two mounting shells 11, and the two fixing plates 18 are rotated inside the first holder 17, and the fixing plate 18 is deflected to one side and enters the inside of the mounting groove 27. An arc-shaped groove is provided at the bottom end of the inner wall of the mounting groove 27, which is aligned with the side end of the fixing plate 18. The fixing plate 18 is rotated to enter the inside of the mounting groove 27 and maintains a horizontal state. By releasing the pulling force on the limit slider 28, the spring rod 29 applies a thrust to the limit slider 28 under the reverse force of the spring rod 29, so that the limit slider 28 moves toward the fixing plate 18 inside the mounting groove 27, and the top of the fixing plate 18 A groove is provided at the end, and one side of the limit slider 28 is a convex design. The limit slider 28 moves to connect the side end of the fixing plate 18. The two mounting shells 11 are first assembled and installed, and two fixing rings 25 are installed on the inner side of the second fixing box 14. A plurality of nozzles 26 are installed inside the fixing ring 25. The protective paint is introduced into the interior of the connecting pipe 19 through the pipeline connecting joint 31. The protective paint solution is pushed to flow inside the connecting pipe 19 into the interior of the fixing ring 25 by using high-pressure airflow, and is sprayed out through a plurality of nozzles 26 to spray the surface of the steel pipe. At the same time, the steel pipe is clamped by the two mounting shells 11, and sprayed by the internal nozzle 26. There is no need to disassemble the fitness equipment additionally, and the operation is more convenient, and the idle time of the fitness equipment is also reduced.

[0030] By pulling the two rotating buckles 38 respectively, the ends of the rotating buckles 38 slide along the top of the connecting shaft 36, and the rotating buckles 38 move outward on the surface of the second fixing box 14, and the rotating buckles 38 drive the two sleeves 39 to move. The sleeves 39 are sleeved on the surface of the rotating buckles 38 and can rotate. At the same time, the two ends of the sleeves 39 are respectively rotated to connect the first pull rod 41. The movement of the sleeves 39 applies a pulling force to the first pull rod 41, so that one end of the first pull rod 41 moves with the sleeves 39. The first pull rod 41 is subjected to the force to move obliquely. The first pull rod 41 is continuously deflected, and the end of the first pull rod 41 applies a pulling force to the two first connecting blocks 34, driving the positioning rod 35 to slide inside the second guide plate 33, and one end of the positioning rod 35 leaves the interior of the positioning hole 16. The first fixing box 13 and the second fixing box 14 are fixed in a state, and by pushing the second fixing box 14, the second fixing box 14 drives the two first fixing boxes 13 to slide inside the first guide plate 12, and the two second fixing boxes 14 respectively enter the interior of the installation shell 11 along the first guide plate 12, driving the two bases 21 to separate. The inner sides of the two bases 21 and the arc blocks 22 are respectively pressed against the surface of the steel pipe, and the steel pipe is subjected to a bidirectional force because the two different bases 21 and the arc blocks 22 are respectively moved and pressed in two symmetrical directions. The two bases 21 and the arc blocks 22 are thrusted in opposite directions, so that the two bases 21 and the arc blocks 22 clamp the steel pipe while increasing the stability of the mounting shell 11. At the same time, the rotating buckle 38 is pushed to move the rotating buckle 38 toward the side end of the second fixing box 14, driving the collar 39 to fit the second fixing box 14. The surface of the fixing box 14, and the ring 39 fits with the surface of the second fixing box 14. During the movement, one end of the first pull rod 41 is pushed to rotate the first pull rod 41 to a horizontal state. The end of the first pull rod 41 applies a reverse thrust to the two first connecting blocks 34, so that the first connecting blocks 34 drive the positioning rod 35 to move in the opposite direction inside the second guide plate 33, and the end of the positioning rod 35 is inserted into the positioning hole 16. A plurality of positioning holes 16 are opened on the inner side of the first guide plate 12, which can be clamped and fixed according to steel pipes of different sizes.

[0031] The second step is to rotate the rotating buckle 38 to rotate the rotating buckle 38 on the outside of the second fixed box 14. At the same time, the rotating buckle 38 and the collar 39 are mechanisms that slide with each other. The rotating buckle 38 drives the collar 39 to rotate inside the second fixed box 14. The end of the rotating buckle 38 is equipped with a bevel gear connected to two transmission rods 37. The two transmission rods 37 are symmetrically installed inside the second fixed box 14. Bevel gears are installed at both ends of the transmission rod 37. At the same time, one end of the transmission rod 37 passes through the first fixed box 13 and the second fixed box 14. One end of the transmission rod 37 fits with the threaded rod 42. The transmission rod 37 and the threaded rod 42 are perpendicular to each other. Through the meshing of the bevel gears, the transmission rod 37 drives the threaded rod 42 to rotate. The threaded rod 42 is mounted inside the first fixed box 13. The end of the threaded rod 42 is a threaded design, which is rotatably connected to the top of the sliding sleeve 32. The end of the threaded rod 42 is inserted into the interior of the sliding sleeve 32. Through the rotation of the threaded rod 42, The threaded rod 42 applies a thrust to allow the threaded rod 42 to slide in a directional manner inside the first fixing box 13. The movement of the threaded rod 42 pushes the two second pull rods 45 to deflect at the bottom end of the threaded rod 42, and at the same time, the other end of the second pull rod 45 is connected to the second connecting block 55, and the second connecting block 55 is respectively connected to the two arc blocks 22. At the same time, the base 21 is fixed on the inner side wall of the mounting shell 11, and the oblique thrust allows the arc block 22 to slide on the side ends of the base 21. The two ends of the base 21 are respectively installed with docking plates 53, and at the same time, a groove is provided inside the arc block 22. Since the docking plate 53 is an arc-shaped design, by pushing the two arc blocks 22 to slide on the side ends of the base 21, the base surface of the base 21 and the arc block 22 is expanded, and at the same time, the angle of the arc block 22 is adjusted, and the arc block 22 drives the first clamping plate 23 and the second clamping plate 24 to deflect, which can increase the force-bearing area. At the same time, the two arc blocks 22 drive the first clamping plate 23 to slide along the docking plate 53, so that the elliptical tube can be quickly fixed.

[0032] At the same time, the second pull rod 45 rotates at the bottom end of the sliding sleeve 32, the second pull rod 45 deflects symmetrically with each other, one end of the second pull rod 45 rotates inside the second connecting block 55, and one end of the second pull rod 45 rotates clockwise inside the second connecting block 55. At the same time, two third pull rods 54 are fixed on both sides of the second connecting block 55, and the second connecting block 55 rotates clockwise, driving the third pull rod 54 to deflect. At the same time, the third pull rod 54 itself is a retractable design, and the third pull rod 54 rotates clockwise. One end of the third pull rod 54 is connected to the side end of the guide slider 46, applying tension to the guide slider 46, so that the guide slider 46 The bottom end of the third guide plate 44 slides toward the side of the arc block 22, and at the same time, the bottom ends of the two guide sliders 46 are respectively connected to the first rotating rod 49 and the second rotating rod 52, and the ends of the first rotating rod 49 and the second rotating rod 52 are respectively rotatably connected to the first push plate 48 and the second push plate 51, pulling the first push plate 48 and the second push plate 51 to slide upward inside the second clamping plate 24 and the first clamping plate 23, and adjusting the first clamping plate 23 and the second clamping plate 24 to a mutually horizontal state. At this time, cooperate with the first clamping plate 23 and the second clamping plate 24 on the other side to form a mutually vertical state, and clamp and fix the square tube and the elliptical square tube.

[0033] In the third step, by rotating the rotating buckle 38 in the opposite direction, the rotating buckle 38 drives the transmission rod 37 to rotate in the opposite direction of the first fixed box 13. The transmission rod 37 is connected to the threaded rod 42. The threaded rod 42 rotating in the opposite direction applies a force to the sliding sleeve 32. The sliding sleeve 32 slides upward inside the first fixed box 13. The sliding sleeve 32 moves upward, applies a pulling force to the two second pull rods 45, and the second pull rods 45 rotate at the bottom end of the sliding sleeve 32. At the same time, the second pull rods 45 deflect upward, and the end of the second pull rod 45 rotates counterclockwise inside the second connecting block 55. The counterclockwise rotating third pull rod 54 moves toward the first One side of the clamping plate 23 deflects, and at the same time, the top end of the third pull rod 54 is rotatably connected to one side of the guide slider 46. At the same time, the two guide sliders 46 are connected by a support rod 47. A spring is installed inside the support rod 47, and the support rod 47 is a multi-section structure. The third pull rod 54 applies a thrust to the guide slider 46, so that one of the guide sliders 46 first drives the second rotating rod 52 to deflect, so that the second rotating rod 52 deflects at the top end of the second push plate 51, and the second rotating rod 52 rotates to a vertical state. The second push plate 51 applies a downward thrust to the second push plate 51, so that the second push plate 51 slides downward inside the first clamping plate 23, and at the same time, the guide slider The guide slider 46 slides at the bottom end of the third guide plate 44 to squeeze the support rod 47. When the support rod 47 is squeezed, the force applied by the third pull rod 54 is transmitted to another guide slider 46 through the support rod 47. The guide slider 46 slides at the bottom end of the third guide plate 44, driving the first rotating rod 49 to deflect. At the same time, the deflection angle of the first rotating rod 49 is different from that of the second rotating rod 52. The deflection angle of the first rotating rod 49 is larger. The guide slider 46 drives the first rotating rod 49 to deflect. The end of the first rotating rod 49 rotates at the top end of the first push plate 48, pushing the first push plate 48 to slide downward inside the second clamping plate 24. The first push plate 48 and the second push plate 51 slide in sections at different distances inside the second clamp plate 24 and the first clamp plate 23 respectively. When the first push plate 48 and the second push plate 51 slide downward to the end inside the second clamp plate 24 and the first clamp plate 23, the two guide sliders 46 continue to slide and apply pressure to the second clamp plate 24 and the first clamp plate 23 respectively, so that the second clamp plate 24 rotates and deflects at the side end of the first clamp plate 23, and at the same time, the first clamp plate 23 rotates and deflects inside the arc block 22, and the first clamp plate 23 and the second clamp plate 24 are bent and compressed inwardly, cooperating with the base 21 and the arc block 22 to clamp and fix the round tube.
