Description

Technical Field

[0001] This utility model belongs to the field of explosion-proof flexible tube processing technology, and specifically relates to a positioning device for explosion-proof flexible tube processing. Background Technology

[0002] Explosion-proof flexible conduit is a flexible connection device specifically designed for explosive hazardous environments, and is mainly used for the protection and connection of circuits in explosion-proof electrical equipment.

[0003] Currently, Chinese utility model patent CN221160044U discloses a positioning device for processing stainless steel explosion-proof flexible tubes. However, this patent uses elastic clamping, which means the flexible tube is subjected to force during processing, and the spring force is easily overcome, making it prone to detachment. Furthermore, although multiple clamping slots are provided, they are uniformly clamped, preventing individual adjustment and limiting its ability to clamp only flexible tubes of a fixed diameter. While the processing angle of the clamped flexible tube can be adjusted, the uniform gear size and the high-speed rotation of the motor directly driving the tube's rotation result in a high speed, hindering precise angle adjustment and thus limiting its practicality. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for processing explosion-proof flexible tubes. Its advantages are that it can easily and securely clamp various explosion-proof flexible tubes of different diameters and can slowly and accurately adjust the processing angle of the explosion-proof flexible tubes.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a positioning device for processing explosion-proof flexible tubes, including a first bearing, a fixed carrier plate and a fixed plate respectively rotatably connected to the side of the first bearing and the second bearing that are close to each other, a threaded shaft rotatably connected between the fixed carrier plate and the fixed plate, a movable carrier plate being threadedly sleeved on the surface of the threaded shaft, and a semi-circular gear rotatably connected to the inside of the first bearing being bolted to the side of the fixed carrier plate away from the movable carrier plate, and a small gear rotatably connected to the first bearing being meshed at the bottom of the surface of the semi-circular gear.

[0006] Using the above technical solution, by rotating the pinion and engaging the semi-circular gear, the semi-circular gear, whose diameter is much larger than the pinion, causes the fixed and movable carrier plates to slowly rotate to both sides between the first and second bearings. This allows for precise adjustment of the processing angle of the explosion-proof flexible tube. By placing multiple explosion-proof flexible tubes of different diameters into the slots, and then individually rotating the screw to drive the abutment plate, a secondary rigid clamping of the explosion-proof flexible tubes in each slot is achieved. This not only makes the processing of the explosion-proof flexible tubes more stable and less prone to falling off, but also allows for clamping various explosion-proof flexible tubes of different diameters, improving practicality.

[0007] The present invention is further configured such that: a lifting plate is slidably connected to the top of both the fixed carrier plate and the movable carrier plate; springs are bolted to both sides of the top of the lifting plate and fixedly connected to the fixed carrier plate and the movable carrier plate respectively; slots are provided on the top of both the fixed carrier plate and the movable carrier plate and at the bottom of the lifting plate; a screw is threaded through the interior of the lifting plate; and a stop plate that cooperates with the slot is welded to the bottom of the screw.

[0008] By adopting the above technical solution, not only can the explosion-proof flexible tube be processed more stably and not easily fall off, but it can also clamp a variety of explosion-proof flexible tubes of different diameters.

[0009] The present invention is further configured such that a scale is marked on the side of the second bearing near the fixed plate.

[0010] The above technical solution facilitates precise adjustment of the rotation angles of the fixed and moving carrier plates by observing the scale, and facilitates accurate processing of explosion-proof flexible tubes.

[0011] The present invention is further configured such that: a handwheel is fixedly sleeved on the surface of the threaded shaft near the fixed plate, and limiting rods bolted to the fixed plate and the fixed plate are slidably connected through both sides inside the movable carrier plate.

[0012] Using the above technical solution, the threaded shaft is rotated by turning the handwheel and engages with the threaded plate of the moving carrier. At the same time, the moving carrier is limited by the limiting rod, so that the moving carrier can slide on the surface of the threaded shaft and adjust the distance between it and the fixed carrier, thereby straightening the explosion-proof flexible tube.

[0013] The present invention is further configured such that: a limiting bolt that engages with a semi-circular gear is threaded through the side of the first bearing away from the fixed carrier plate.

[0014] Using the above technical solution, by turning the limiting bolt out of the first bearing, the pinion can drive the semi-circular gear to rotate. When the limiting bolt turns back into the first bearing, the semi-circular gear can be secured by the threaded meshing friction, thereby limiting the angle of the fixed plate and the moving plate after rotation adjustment.

[0015] The present invention is further configured such that a screw cap is welded to the end of the pinion away from the interior of the first bearing and the end of the screw away from the interior of the lifting plate.

[0016] The above technical solution facilitates adjustment by turning the screw cap to drive the pinion or screw to rotate.

[0017] The present invention is further provided with: the inner surface of the slot is provided with anti-slip pads that are respectively bonded to the fixed carrier plate, the movable carrier plate and the lifting plate.

[0018] By adopting the above technical solution, the friction of the inner surface of the slot is increased to prevent the explosion-proof flexible tube from coming loose when it is clamped inside the slot.

[0019] The present invention is further configured such that: both ends of the lifting plate are slidably connected with positioning rods, and the springs are sleeved on the surface of the positioning rods.

[0020] By adopting the above technical solution, the stability of the lifting plate sliding up and down on the top of the fixed or moving carrier plate is improved, making it easier to stably lock the two ends of the explosion-proof flexible tube inside the slot.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. By rotating the pinion gear and engaging the semi-circular gear, the diameter of the semi-circular gear is much larger than that of the pinion gear, thus causing the fixed carrier plate and the moving carrier plate to slowly rotate to both sides between the first and second bearings. This allows for precise adjustment of the processing angle of the explosion-proof flexible conduit.

[0023] 2. By placing multiple explosion-proof flexible tubes of different diameters into the slots, and then individually rotating the screw to drive the abutment plate to perform a secondary rigid clamping of the explosion-proof flexible tubes in different slots, the processing of the explosion-proof flexible tubes is made more stable and less prone to falling off. It can also clamp various explosion-proof flexible tubes of different diameters, improving practicality. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] refer to Figure 1 , Figure 3The explosion-proof flexible tube processing positioning device includes a first bearing 1. A fixed carrier plate 4 and a fixed plate 3 are rotatably connected to the sides of the first bearing 1 and second bearing 2 respectively, close to each other. A threaded shaft 5 is rotatably connected between the fixed carrier plate 4 and the fixed plate 3. A movable carrier plate 6 is threadedly fitted onto the surface of the threaded shaft 5. A semi-circular gear 7, rotatably connected to the inside of the first bearing 1, is bolted to the side of the fixed carrier plate 4 away from the movable carrier plate 6. A small gear 8, rotatably connected to the first bearing 1, meshes with the bottom of the surface of the semi-circular gear 7. By rotating the small gear 8 to mesh with the semi-circular gear 7, since the diameter of the semi-circular gear 7 is much larger than that of the small gear 8, the fixed carrier plate 4 and the movable carrier plate 6 will slowly rotate to both sides between the first bearing 1 and the second bearing 2. This allows for precise adjustment of the processing angle of the explosion-proof flexible tube.

[0031] refer to Figure 1 The second support 2 has a scale 14 marked on the side near the fixed plate 3. This allows for precise adjustment of the rotation angle of the fixed carrier plate 4 and the movable carrier plate 6 by observing the scale 14, facilitating accurate processing of the explosion-proof flexible tube.

[0032] refer to Figure 1 A handwheel 15 is fixedly sleeved on the surface of the threaded shaft 5 near the fixed plate 3. Limiting rods 16, bolted to the fixed plate 4 and the fixed plate 3, are slidably connected to both sides of the movable carrier plate 6. Rotating the handwheel 15 causes the threaded shaft 5 to rotate and engage with the threaded portion of the movable carrier plate 6. Simultaneously, the limiting rods 16 limit the movement of the movable carrier plate 6, allowing it to slide on the surface of the threaded shaft 5, adjusting the distance between it and the fixed plate 4, thereby straightening the explosion-proof flexible conduit.

[0033] refer to Figure 1 The first bearing 1, on the side away from the fixed carrier plate 4, is threaded with a limiting bolt 17 that engages with the semi-circular gear 7. By rotating the limiting bolt 17 out of the first bearing 1, the pinion 8 can drive the semi-circular gear 7 to rotate. When the limiting bolt 17 rotates back into the first bearing 1, the semi-circular gear 7 can be secured by the threaded engagement friction, thereby limiting the angle after the fixed carrier plate 4 and the movable carrier plate 6 have been rotated and adjusted.

[0034] Brief description of the usage process: By rotating the pinion 8 to mesh with the semi-circular gear 7, since the diameter of the semi-circular gear 7 is much larger than that of the pinion 8, the pinion 8 will drive the semi-circular gear 7 to rotate slowly. Then, the semi-circular gear 7 drives the fixed carrier plate 4 and the fixed plate 3 to rotate slowly between the first bearing 1 and the second bearing 2, thereby driving the fixed carrier plate 4 and the movable carrier plate 6 to rotate slowly to both sides to adjust the processing angle of the explosion-proof flexible tube. Finally, the adjusted angle is locked and limited by rotating the limit bolt 17.

[0035] Example 2:

[0036] refer to Figure 1 , Figure 2 The explosion-proof flexible tube processing positioning device has a lifting plate 9 slidably connected to the top of both the fixed carrier plate 4 and the movable carrier plate 6. Springs 10, respectively fixedly connected to the fixed carrier plate 4 and the movable carrier plate 6, are bolted to both sides of the top of the lifting plate 9. Slots 11 are provided on the top of the fixed carrier plate 4 and the movable carrier plate 6, as well as at the bottom of the lifting plate 9. A screw 12 is threaded through the inside of the lifting plate 9, and a stop plate 13, which mates with the slot 11, is welded to the bottom of the screw 12. By placing multiple explosion-proof flexible tubes of different diameters into the slots 11, and then individually rotating the screw 12 to drive the stop plate 13, a secondary rigid clamping is performed on the explosion-proof flexible tubes inside the different slots 11. This not only makes the explosion-proof flexible tubes more stable during processing and less prone to falling off, but also allows for clamping various explosion-proof flexible tubes of different diameters, improving practicality.

[0037] refer to Figure 1 , Figure 2 Both the end of the pinion 8 furthest from the interior of the first bearing 1 and the end of the screw 12 furthest from the interior of the lifting plate 9 are welded with a cap 18. This allows for adjustment by turning the cap 18 to rotate the pinion 8 or the screw 12 respectively.

[0038] refer to Figure 1 , Figure 2 The inner surface of the slot 11 is provided with anti-slip pads 19 that are respectively bonded to the fixed carrier plate 4, the movable carrier plate 6, and the lifting plate 9. This increases the friction of the inner surface of the slot 11 and prevents the explosion-proof flexible tube from coming loose when it is clamped inside the slot 11.

[0039] refer to Figure 2 Both ends of the lifting plate 9 are slidably connected to positioning rods 20, and springs 10 are sleeved on the surface of the positioning rods 20. This improves the stability of the lifting plate 9 as it slides up and down on the top of the fixed carrier plate 4 or the movable carrier plate 6, and makes it easier to stably lock both ends of the explosion-proof flexible tube inside the slot 11.

[0040] Brief description of the usage process: By pulling the lifting plate 9 upward to overcome the elastic force of the spring 10, the slots 11 at the top of the fixed carrier plate 4 and the movable carrier plate 6 can be opened simultaneously. Then, multiple explosion-proof flexible tubes of different diameters are placed as needed, and after the lifting plate 9 is lowered, the spring force of the spring 10 is used to clamp and initially position the explosion-proof flexible tubes. Afterwards, by individually rotating the screw 12 to engage with the threaded lifting plate 9, the abutment plate 13 is moved downward to perform a secondary rigid tightening of the explosion-proof flexible tubes inside the different slots 11.

[0041] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
