Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, and more specifically, to a steel bar threaded connection device. Background Technology

[0002] When processing reinforcing bars, there are situations where two bars need to be connected using sleeves to extend their length. This requires the use of a reinforcing bar connector for installation or disassembly. Most existing connectors clamp onto the reinforcing bar, and a motor or electric gun drives the clamped part to rotate, thus rotating the reinforcing bar for installation or disassembly. However, since the actual working environment of reinforcing bars is mostly on construction sites, the conditions of different reinforcing bars vary. Reinforcing bars may have mud or rust on them. When the connector is driven, this mud or rust may enter the connector's interior. Therefore, lubrication of the drive mechanism inside the connector is necessary. Current lubrication methods typically involve the operator finding grease after feeling a jam, applying it to the clamped part of the reinforcing bar, and then rotating it to draw the grease into the device. This process is relatively complex. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a rebar thread connection device with the advantage of convenient lubrication.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a rebar threaded connection device, comprising a housing, wherein a transmission component is movably connected inside the housing, and a drive component is provided above the housing;

[0005] A connecting assembly is fixedly installed on the front side of the outer shell. The connecting assembly includes a fixed shell, a positioning frame is fixedly installed in the middle of the fixed shell, and a bevel gear is rotatably connected to the middle of the positioning frame.

[0006] The top of the fixed shell is provided with an injection assembly, which includes a flange and a replenishment box. A connecting block is fixedly installed at the rear end of the flange, a pressure plate is fixedly installed at the bottom end of the connecting block, a one-way hole is fixedly installed at the front end of the replenishment box, and a through hole is opened at the top of the shell.

[0007] As a preferred embodiment of the present invention, the connecting assembly further includes a movable shaft, which is movably connected to the second bevel gear, and a safety spring is sleeved on the surface of the movable shaft.

[0008] As a preferred embodiment of this utility model, the transmission component includes a locking block, which is rotatably connected to the bottom end of the housing. A driven gear and a driving gear are rotatably connected to the middle of the housing. A bevel gear is fixedly installed at the front end of the driving gear, and a positioning clamp is fixedly installed at the rear end of the housing.

[0009] As a preferred embodiment of this utility model, the driving assembly includes a driving electric gun, a connecting flange is fixedly installed at the bottom end of the driving electric gun, and a transmission shaft is fixedly sleeved at the output end of the bottom end of the driving electric gun.

[0010] As a preferred technical solution of this utility model, the connecting flange and the flange frame are fixedly connected by bolts, and the transmission shaft is inserted into the regular hexagonal hole opened at the top of the moving shaft.

[0011] As a preferred technical solution of this utility model, the first bevel gear meshes with the second bevel gear, there are two driven gears, the two driven gears are located on the left and right sides of the inner cavity of the outer shell respectively, and both driven gears mesh with the driving gear and the locking block.

[0012] As a preferred technical solution of this utility model, the bottom end of the card block is provided with a "U" shaped groove, and the distance between the two driven gears is less than the width of the "U" shaped groove at the bottom end of the card block.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses a flange that can move up and down. When placed on a steel bar, the flange can be pressed down by driving the electric gun. This causes the pressure plate to move down in the replenishment box, injecting the grease in the replenishment box into the outer shell for replenishment. This replenishes the components inside the outer shell and simultaneously causes the grease to flow inside the outer shell to improve the lubrication effect. This achieves automatic grease replenishment and is easy to operate.

Only after pressure is applied to the drive electric gun can the movable shaft and the second bevel gear be positioned and connected in the horizontal direction. When the device is not in use, the elasticity of the safety spring can push the movable shaft and the second bevel gear apart, thus separating the second bevel gear from the movable shaft. After separation, even if the drive electric gun is accidentally activated, it cannot drive the locking block to rotate, thereby avoiding injury to personnel due to accidental activation of the locking block and improving safety.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figures 1 to 6As shown, this utility model provides a rebar threaded connection device, including a housing 101, a transmission component movably connected inside the housing 101, and a drive component provided above the housing 101;

[0029] A connecting assembly is fixedly installed on the front side of the outer shell 101. The connecting assembly includes a fixed shell 201, a positioning frame 202 is fixedly installed in the middle of the fixed shell 201, and a bevel gear 203 is rotatably connected to the middle of the positioning frame 202.

[0030] The top of the fixed shell 201 is provided with an injection assembly, which includes a flange 301 and a replenishment box 305. A connecting block 302 is fixedly installed at the rear end of the flange 301, and a pressure plate 303 is fixedly installed at the bottom end of the connecting block 302. A one-way hole 304 is fixedly installed at the front end of the replenishment box 305, and a through hole 306 is opened at the top of the shell.

[0031] The transmission assembly includes a locking block 102, which is rotatably connected to the bottom end of the housing 101. A driven gear 103 and a driving gear 104 are rotatably connected to the middle of the housing 101. A bevel gear 105 is fixedly mounted at the front end of the driving gear 104. A positioning clamp 106 is fixedly mounted at the rear end of the housing 101. The drive assembly includes a drive electric gun 401, with a connecting flange 402 fixedly mounted at its bottom end. A drive shaft 403 is fixedly sleeved at the output end of the drive electric gun 401. The bevel gear 105 meshes with the bevel gear 203. There are two driven gears 103. Driven gears 103 are located on the left and right sides of the inner cavity of housing 101, respectively. Both driven gears 103 mesh with driving gear 104 and locking block 102. The bottom end of locking block 102 is provided with a "U" shaped groove. The distance between the two driven gears 103 is less than the width of the "U" shaped groove at the bottom end of locking block 102. The inner wall of fixed housing 201 is provided with a square groove. The bottom end of flange bracket 301 is fixedly installed with a positioning piece, which is slidably connected in the square groove. Through hole 306 connects housing 101 and replenishment box 305. The top end of housing 101 is provided with an addition hole, and a sealing plug is inserted into the addition hole.

[0032] By providing an addition hole, a large amount of grease can be added directly to the housing 101 after the sealing plug is opened, making it convenient and easy to use. A square groove is provided to vertically position the movement of the positioning plate, preventing the flange 301 from rotating and ensuring its stability against offset or skew. A U-shaped groove is provided to allow the reinforcing bar to enter the center of the clamping block 102. A figure-eight shaped clamping strip is fixedly installed on the front side of the clamping block 102 to accommodate reinforcing bars of different diameters. Setting the diameter between the two driven gears 103 to be greater than the width of the U-shaped groove ensures that at least one driven gear 103 is engaged when the U-shaped groove rotates to the top. 03 engages with the locking block 102 to ensure smooth operation of the device. The drive electric gun 401 serves as a power generation mechanism, driving the transmission shaft 403 to rotate and thus drive the device. The flange 301, which can move up and down, can be pressed down on the reinforcing bar by pressing down the drive electric gun 401. This causes the pressure plate 303 to move down in the replenishment box 305, injecting the grease in the replenishment box 305 into the outer shell 101 for replenishment. This lubricates the components inside the outer shell 101 and simultaneously allows the grease to flow within the outer shell 101, improving the lubrication effect. This achieves automatic grease replenishment and is easy to operate.

[0033] Example 2

[0034] like Figures 3 to 5 As shown, this utility model provides a rebar threaded connection device. The connection component also includes a movable shaft 204, which is movably connected to a bevel gear 203. A safety spring 205 is sleeved on the surface of the movable shaft 204. A transmission rod is fixedly installed at the bottom end of the movable shaft 204. A transmission hole is opened at the top end of the bevel gear 203, which is located directly below the transmission rod. The safety spring 205 is sleeved on the surface of the transmission rod.

[0035] After the movable shaft 204 is pressed down, the transmission rod can be pressed into the transmission hole. After the drive electric gun 401 is started, the drive electric gun 401 drives the movable shaft 204 and the second bevel gear 203 to rotate through the transmission shaft 403. This drives the first bevel gear 105 and the driving gear 104 to rotate. Through the meshing of the driven gear 103 and the locking block 102, the locking block 102 can be driven to rotate, ultimately driving the steel bar to rotate. By setting the movable shaft 204, which can float up and down, between the second bevel gear 203 and the transmission shaft 403, the rotation is achieved. Only after pressure is applied to the drive electric gun 401 can the moving shaft 204 and the second bevel gear 203 be positioned and connected in the horizontal direction. When the device is not in use, the elasticity of the safety spring 205 can push the moving shaft 204 and the second bevel gear 203 apart, so that the second bevel gear 203 is separated from the moving shaft 204. After separation, even if the drive electric gun 401 is accidentally activated, it will not be able to drive the locking block 102 to rotate, thereby avoiding injury to personnel due to accidental activation of the locking block 102 and improving safety.

[0036] Example 3

[0037] like Figure 2 As shown, this utility model provides a rebar threaded connection device, wherein the connecting flange 402 and the flange bracket 301 are fixedly connected by bolts, and the transmission shaft 403 is inserted into the regular hexagonal hole opened at the top of the movable shaft 204.

[0038] The connecting flange 402 and the flange frame 301 are fixedly connected by bolts. The bolts can be removed to remove the drive electric gun 401 and to replace it with different drive electric guns 401 to meet different torque requirements. Different shapes of drive electric guns 401 are used in different application scenarios. The motor can also be directly installed on the flange frame 301 to reduce the volume occupied by the device and the dependence on the swing battery power.

[0039] Working principle and usage process of this utility model:

[0040] When in use, two steel bars need to be connected or disassembled. The positioning clamp 106 is clamped on one of the steel bars, and then the opening of the clamping block 102 is aligned with the other steel bar. The outer shell 101 is pressed down so that the clamping block 102 is clamped on the steel bar. Then the drive electric gun 401 is pressed down so that the drive electric gun 401 drives the flange 301 to slide down, thereby driving the connecting block 302 and the moving shaft 204 to press down.

[0041] After the movable shaft 204 is pressed down, the transmission rod can be pressed into the transmission hole. After the connecting block 302 is pressed down, the pressure plate 303 can be moved down in the replenishment box 305, squeezing the grease in the replenishment box 305 into the housing 101. While replenishing the grease in the housing 101, it can also drive the grease in the housing 101 to move, thereby achieving lubrication of the components in the housing 101.

[0042] Then, the drive electric gun 401 is started. The drive electric gun 401 drives the moving shaft 204 and the second bevel gear 203 to rotate through the transmission shaft 403, which in turn drives the first bevel gear 105 and the driving gear 104 to rotate. Through the meshing of the driven gear 103 and the locking block 102, the locking block 102 can be driven to rotate, and finally the steel bar is driven to rotate.
