Description

Technical Field

[0001] This utility model relates to the field of threaded sleeve technology, specifically to a threaded sleeve connection device. Background Technology

[0002] In the construction industry, threaded sleeve mechanical connections have been widely used. In the process of connecting steel bars with threaded sleeves, the connection between the steel bar threads and the threaded sleeve is generally achieved by tightening with a pipe wrench or steel bar wrench. First, one steel bar is fixed in place, the threaded sleeve is screwed on, and then the other corresponding steel bar is screwed into the threaded sleeve until the connection between the two steel bars is completed, thus completing the connection between the steel bar and the threaded sleeve.

[0003] According to a publicly disclosed threaded sleeve connection device (publication number: CN217167370U), the above application uses a first cylinder to drive a support plate to move to the left via a first output shaft, facilitating the screwing of a reinforcing bar into the threaded sleeve. A spring fixes the reinforcing bar in a rotating shaft, and a motor drives the reinforcing bar to rotate via the rotating shaft, thereby screwing the reinforcing bar into the threaded sleeve. A slider slides in a groove to restrict the position of the support plate. A second cylinder drives a transmission plate to move downward via an output shaft, and the transmission plate drives a fixing plate to move downward via a transmission rod, facilitating the fixing of the threaded sleeve. The main arc groove and the secondary arc groove cooperate to facilitate the fixing of the threaded sleeve position.

[0004] However, in the aforementioned application, simply using springs to fix the reinforcing bars is often insufficient in practice to maintain their stability during rotation, especially when the reinforcing bars have a large diameter or are made of hard material. This can easily lead to slippage. This not only affects the connection quality between the reinforcing bar and the threaded sleeve but may also damage the connection device itself, increasing construction costs and risks. Utility Model Content

[0005] The purpose of this utility model is to provide a threaded sleeve connection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a threaded sleeve connection device, including a base, a cylinder fixed to the top of the base, a fixing plate fixed to the output end of the cylinder, the fixing plate being slidably connected to the top of the base, a motor fixed to the left side of the fixing plate, a fixing component for fixing reinforcing bars provided on the surface of the output shaft of the motor, a stabilizing plate fixed to the top of the base, and a positioning component for convenient centering and fixing provided on the surface of the stabilizing plate, the fixing component including:

[0007] A circular plate is fixed to the surface of the output shaft of the motor. A fixing frame is fixed to the left side of the circular plate. A cavity is opened inside the fixing frame. A rotating plate is rotatably connected to the inner wall of the cavity.

[0008] Preferably, the fixing component further includes a movable hole, which is formed on the surface of the rotating plate. The inner wall of the movable hole abuts against a short rod. A stabilizing block is fixed to the surface of the short rod. The left side of the stabilizing block passes through the fixing frame and is slidably connected to the fixing frame. A clamping block is fixed to the left side of the stabilizing block. A through hole is formed on the surface of the fixing frame. A locking tooth is fixed to the surface of the rotating plate and passes through the through hole. A knob is rotatably connected to the surface of the circular plate. The output shaft of the knob passes through a gear and is fixedly connected to the knob and the gear. The gear meshes with the locking tooth. The movable hole is arc-shaped. The fixing component also includes a limiting member. Rotating the knob, the gear, and the locking tooth can synchronously drive the rotating plate to rotate. The inner wall of the movable hole abuts against the surface of the short rod, which can drive the stabilizing block and the clamping block to move radially synchronously. This allows the clamping block to clamp the pair of reinforcing bars, preventing displacement during subsequent connection.

[0009] Preferably, the limiting component includes a sliding plate through which a knob passes and is slidably connected to the knob. A rod is fixed to the surface of the sliding plate, with a gear passing through the end of the rod away from the sliding plate. A spring is fixed to the surface of the sliding plate, with the end of the spring away from the sliding plate fixed to the surface of the gear. A slot is formed on the surface of the circular plate, and a stabilizing hole is formed on the surface of the sliding plate. A rotating rod is rotatably connected to the surface of the gear, with a baffle fixed to the end of the rotating rod away from the gear. A fixing block is fixed to the surface of the gear, and a sliding groove is formed on the inner side of the fixing block. A movable column is slidably connected to the inner wall of the sliding groove, and a second spring is fixed to the surface of the movable column, with the end of the second spring away from the movable column fixed to the inner wall of the sliding groove. A stabilizing groove is formed on the surface of the rotating rod. When clamped, releasing the sliding plate causes the spring to move the sliding plate and the rod back to their original positions, and the rod enters the slot, thus limiting the knob and gear. Rotating the baffle again causes the baffle position to intersect with the stabilizing hole, thus limiting the sliding plate. This prevents accidental contact with the sliding plate during connection, which could cause the knob and gear to rotate.

[0010] Preferably, the positioning component includes a second rotating plate, the surface of which has a second movable hole, and a connecting frame is fixed to the surface of the stabilizing plate. The second rotating plate is rotatably connected to the inner side of the connecting frame. The inner wall of the second movable hole abuts against a second short rod, and a second clamping block is fixed to the surface of the second short rod. The second clamping block penetrates the connecting frame and is slidably connected to the connecting frame. There are four sets of second clamping blocks, and all four sets of second clamping blocks are arranged in a circumferential array with the center of the connecting frame as the axis. A bolt is rotatably connected to the surface of one set of second clamping blocks. The end of the bolt away from the second clamping block penetrates the connecting frame and is threadedly connected to the connecting frame. By rotating the bolt, the second clamping block moves closer to the threaded sleeve. Through the second short rod, each second clamping block moves radially synchronously, thereby fixing the threaded sleeve.

[0011] Preferably, the end of the movable column away from the second spring is set in an arc shape. When the rotating rod rotates, the inner wall of the stabilizing groove abuts against the surface of the movable column, thereby driving the movable column into the sliding groove.

[0012] Preferably, the second movable hole is arc-shaped, which allows the second short rod and the second clamping block to move radially synchronously when rotating with the second rotating plate.

[0013] Preferably, the surface of the stabilizing plate has a placement hole to facilitate the placement of the threaded sleeve.

[0014] Compared with the prior art, this utility model provides a threaded sleeve connection device, which has the following features:

[0015] Beneficial effects:

[0016] 1. This threaded sleeve connection device, through the set fixing components, places the reinforcing bar on the surface of the fixed frame. Pulling the sliding plate causes the insert rod to disengage from the slot. Turning the knob causes the gear, locking teeth, and rotating plate to rotate. The inner wall of the movable hole abuts against the surface of the short rod, which drives the stabilizing block and clamping block to move radially in sync. This clamping block clamps the reinforcing bar, preventing misalignment during subsequent connection. When clamping, releasing the sliding plate causes the spring to drive the sliding plate and insert rod to reset. The insert rod then enters the slot, limiting the knob and gear. Turning the baffle again causes the baffle position to intersect with the stabilizing hole, limiting the sliding plate. This prevents accidental contact with the sliding plate during connection, which could cause the knob and gear to rotate and affect the stability of the reinforcing bar.

[0017] 2. The threaded sleeve connection device, through the positioning component, places the threaded sleeve into the placement hole of the stabilizing plate. By rotating the bolt, the clamping block two moves closer to the threaded sleeve. Through the short rod two, each clamping block two moves radially synchronously, thus fixing the threaded sleeve. At this time, the center of the threaded sleeve and the center of the reinforcing bar are on the same horizontal line, which facilitates subsequent connection. Attached Figure Description

[0025] like Figures 1-6 As shown, this utility model provides a technical solution: a threaded sleeve connection device, including a base 1, a cylinder 2 fixed to the top of the base 1, a fixing plate 3 fixed to the output end of the cylinder 2, the fixing plate 3 slidably connected to the top of the base 1, a motor 4 fixed to the left side of the fixing plate 3, a fixing component 5 for fixing reinforcing bars provided on the surface of the output shaft of the motor 4, a stabilizing plate 6 fixed to the top of the base 1, and a positioning component 7 for convenient centering and fixing provided on the surface of the stabilizing plate 6. 5 includes: a circular plate 50, a fixed frame 51, a cavity 52, a rotating plate 53, a short rod 54, a stabilizing block 55, a clamping block 56, a through hole 57, a locking tooth 58, a gear 500, a knob 501, a movable hole 502, a limiting component 59, a sliding plate 590, a plug rod 591, a spring 592, a slot 593, a stabilizing hole 594, a baffle 595, a rotating rod 596, a fixed block 597, a sliding groove 598, a movable column 599, a second spring 5900, and a stabilizing groove 5901.

[0026] A circular plate 50 is fixed to the output shaft surface of the motor 4. A fixing frame 51 is fixed to the left side of the circular plate 50. A cavity 52 is opened inside the fixing frame 51. A rotating plate 53 is rotatably connected to the inner wall of the cavity 52. ​​The fixing assembly 5 also includes a movable hole 502, which is opened on the surface of the rotating plate 53. A short rod 54 abuts against the inner wall of the movable hole 502. A stabilizing block 55 is fixed to the surface of the short rod 54. The left side of the stabilizing block 55 passes through the fixing frame 51, and the stabilizing block 55 is slidably connected to the fixing frame 51. A clamping block 56 is fixed to the left side of the stabilizing block 55. A through hole 57 is opened on the surface of the fixing frame 51. The surface of the rotating plate 53 is fixed with a locking tooth 58, which passes through the through hole 57. The surface of the circular plate 50 is rotatably connected with a knob 501. The output shaft of the knob 501 passes through the gear 500, and the knob 501 is fixedly connected to the gear 500. The gear 500 meshes with the locking tooth 58. The movable hole 502 is set in an arc shape. The fixing component 5 also includes a limiting member 59. When the knob 501 and the gear 500 are rotated, the locking tooth 58 is driven to rotate. The inner wall of the movable hole 502 abuts against the surface of the short rod 54, which drives the stabilizing block 55 and the clamping block 56 to move radially in sync, so that the clamping block 56 can clamp the steel bar.

[0027] The limiting component 59 includes a sliding plate 590, through which a knob 501 passes, and the sliding plate 590 is slidably connected to the knob 501. A rod 591 is fixed to the surface of the sliding plate 590, with one end of the rod 591 away from the sliding plate 590 passing through a gear 500. A spring 592 is fixed to the surface of the sliding plate 590, with one end of the spring 592 away from the sliding plate 590 fixed to the surface of the gear 500. A slot 593 is formed on the surface of the circular plate 50, and a stabilizing hole 594 is formed on the surface of the sliding plate 590. A rotating rod 596 is rotatably connected to the surface of the gear 500, with a baffle 595 fixed to one end of the rotating rod 596 away from the gear 500. A fixing block 597 is fixed to the surface of the gear 500, and a groove 598 is formed on the inner side of the fixing block 597. The inner wall of the groove 598 is slidably connected to... A movable column 599 is connected, and a second spring 5900 is fixed to the surface of the movable column 599. The end of the second spring 5900 away from the movable column 599 is fixed to the inner wall of the slide groove 598. A stabilizing groove 5901 is opened on the surface of the rotating rod 596. The end of the movable column 599 away from the second spring 5900 is set to be arc-shaped. When clamping, the slide plate 590 is released, and the first spring 592 drives the slide plate 590 and the insertion rod 591 to return to their original positions. The insertion rod 591 enters the slot 593, which can limit the knob 501 and the gear 500. The baffle 595 is rotated again so that the position of the baffle 595 is staggered with the stabilizing hole 594, which can limit the slide plate 590. This can prevent the knob 501 and the gear 500 from being accidentally touched during connection, which would affect the stability of the steel bar.

[0028] The positioning component 7 includes a rotating plate 70, with a movable hole 72 on its surface. A connecting frame 71 is fixed to the surface of the stabilizing plate 6. The rotating plate 70 is rotatably connected to the inner side of the connecting frame 71. A short rod 73 abuts against the inner wall of the movable hole 72. A clamping block 74 is fixed to the surface of the short rod 73, penetrating the connecting frame 71 and slidably connected to it. Four sets of clamping blocks 74 are provided, and each set is arranged in a circular array around the center of the connecting frame 71. One set of components 74 has a rotatable connection to a bolt 75. The end of the bolt 75 furthest from the clamping block 74 passes through the connecting frame 71, and the bolt 75 is threadedly connected to the connecting frame 71. The movable hole 72 is arc-shaped. When the threaded sleeve is placed into the placement hole of the stabilizing plate 6, rotating the bolt 75 causes the clamping block 74 to move closer to the threaded sleeve. Through the short rod 73, all clamping blocks 74 move radially synchronously, thus fixing the threaded sleeve. At this point, the center of the threaded sleeve and the center of the reinforcing bar are on the same horizontal line, facilitating subsequent connections. The surface of the stabilizing plate 6 has a placement hole for the threaded sleeve to pass through.

[0029] When connection is required, place the reinforcing bar on the surface of the fixed frame 51. Rotate the baffle 595 so that its position is parallel to the stabilizing hole 594. Simultaneously, as the baffle 595 rotates, it drives the rotating rod 596 to rotate. At this time, the inner wall of the stabilizing groove 5901 abuts against the surface of the movable column 599, causing the movable column 599 to enter the sliding groove 598, compressing the spring 5900. When the movable column 599 is parallel to the stabilizing groove 5901, the spring 5900 is released, thus stabilizing the rotating rod 596 and the baffle 595. Then, pull the sliding plate 590 to disengage the insertion rod 591 from the slot 593. Normally rotate the knob 501 and gear 500, causing the locking tooth 58 to rotate. The inner wall of the movable hole 502 abuts against the surface of the short rod 54, thus driving the stabilizing block 55 and the clamping block 56 to move radially synchronously, clamping the reinforcing bar. When clamping, release the sliding plate 590, and the spring... 592 drives the slide plate 590 and the insertion rod 591 to reset. At this time, the insertion rod 591 enters the slot 593, which limits the knob 501 and gear 500. Rotating the baffle 595 again makes the position of the baffle 595 intersect with the stabilizing hole 594, which limits the slide plate 590. This can prevent the knob 501 and gear 500 from rotating due to accidental contact with the slide plate 590 during connection, which would affect the stability of the steel bar. At this time, the threaded sleeve is placed into the placement hole of the stabilizing plate 6. Rotating the bolt 75 will make the clamping block 74 move closer to the threaded sleeve. Through the short rod 73, each clamping block 74 moves radially synchronously, which can fix the threaded sleeve. At this time, the center of the threaded sleeve and the center of the steel bar are on the same horizontal line. At this time, the cylinder 2 can be opened, which makes the fixing plate 3 drive the motor 4 and the circular plate 50 to move closer to the stabilizing plate 6. At the same time, the motor 4 is turned on, which makes the fixing component 5 and the steel bar rotate, and the connection can be made.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
