Description

Technical Field

[0001] The utility model relates to the technical field of double-headed screws, and particularly relates to a double-headed screw with high stability and high brightness. Background Technique

[0002] Double-headed bolts are mainly used for the fixed connection function of machinery. They have threads at both ends and a screw rod in the middle, with different thicknesses. They are applicable to mining machinery, bridges, automobiles, motorcycles, boiler steel structures, tower cranes, large-span steel structures, and large buildings, etc.

[0003] When using a double-headed bolt, some users, for the sake of convenience in holding, will directly pinch the end of the double-headed bolt that is not installed in the device, and then rotate the bolt with their fingers to insert one end of the bolt into the machinery that needs to be connected. However, if the environment where the bolt is placed is not good, there may be some impurities adsorbed inside the threads. These impurities will block the surface of the bolt and affect the overall brightness of the bolt. Moreover, when the user screws the bolt into the machinery, the small impurities in the threads may pierce into the user's hand. And these small impurities may jam the bolt in the screw hole when using the bolt, making it rather inconvenient to use. To solve this technical problem, the utility model proposes a double-headed screw with high stability and high brightness. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a double-headed screw with high stability and high brightness, which can effectively solve the problems mentioned in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A double-headed screw with high stability and high brightness, including a screw rod body. A chute is provided inside the screw rod body. A clamping plate is clamped inside the screw rod body. A sleeve ring is connected to the outer surface of the clamping plate. A brush is installed on the outer surface of the sleeve ring. A limiting plate is threadedly connected inside the screw rod body. An anti-slip block is connected to the outer surface of the limiting plate. A cross bar is connected to the outer surface of the limiting plate. A spring is connected inside the cross bar. A limiting block is connected to the output end of the spring. A limiting rod is connected to the outer surface of the cross bar.

[0007] Preferably, a support rod is connected inside the screw rod body. An adjusting plate is rotatably connected to the outer surface of the support rod.

[0008] Preferably, the outer surface of the adjusting plate is slidably connected to the inside of the screw rod body. An adjusting block is connected to the upper surface of the adjusting plate.

[0009] Preferably, a blocking block is clamped inside the screw rod body. An insertion block is connected inside the blocking block. The outer surface of the insertion block is slidably connected to the inside of the adjusting plate.

[0010] Preferably, the outer surface of the clamping plate is slidably connected to the inside of the barrier block, and the outer surface of the collar is in contact with the outer surface of the barrier block.

[0011] Preferably, the outer surface of the brush is slidably connected to the outer surface of the screw body, the outer surface of the anti-slip block is slidably connected to the inside of the screw body, and the outer surface of the cross bar is slidably connected to the inside of the screw body.

[0012] Preferably, the outer surface of the limit block is slidably connected to the inside of the cross bar, the outer surface of the limit block is slidably connected to the inner side wall of the chute, and the outer surface of the limit rod is slidably connected to the inside of the limit block.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, through the cooperation between components such as the brush and the cross bar, first, the brush can move. When the user uses the device, the user needs to first remove the collar from the threaded rod. When removing the collar, the user can rotate it to let the brush clean the fine impurities hidden in the thread of the screw body, so that these fine impurities will not get stuck in the device when the screw body is connected to the device. The cross bar can be pulled out from the screw body. When the user picks up the screw, the cross bar can be pulled out from the inside of the screw, so that the user can move the screw body by holding the cross bar, without the user having to hold the threaded part of the screw body, thus avoiding the user being pricked by fine impurities and preventing the dirt on the hand from being printed on the bolt, which is very convenient and solves the problem of inconvenient use due to fine impurities in the thread. At the same time, by cleaning the impurities in the thread, the stability of the device is improved, and by reducing the direct contact of the user with the surface of the bolt, the high gloss of the bolt body itself when it is manufactured is prevented from being covered with dust.

[0015] In the utility model, through the cooperation between components such as the adjusting plate and the insertion block, the adjusting plate can be opened. After the adjusting plate is opened, the user can move the adjusting plate to make the support rod drive the threaded rod body to rotate, so that the user can tightly connect one end of the screw body to the machine without using external objects. The insertion block can be inserted into the inside of the adjusting plate. By inserting the insertion block into the inside of the adjusting plate, the adjusting plate cannot be unfolded, so that after the screw body connects the two machines together, the adjusting block will not be opened due to shaking, and the stability is high and it is very easy to use.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, a high-stability and high-brightness double-headed screw includes a screw body 1. A chute 2 is provided inside the screw body 1, and a clamping plate 3 is clamped inside the screw body 1. The inner side wall of the chute 2 is relatively smooth, and the friction force received by other objects when moving on the inner side wall of the chute 2 is small. After the clamping plate 3 is inserted into the screw body 1, the screw body 1 will limit the position of the clamping plate 3.

[0024] A collar 4 is connected to the outer surface of the clamping plate 3, and a brush 5 is installed on the outer surface of the collar 4. The clamping plate 3 will fix the position of the collar 4, and when the collar 4 moves, it will drive the clamping plate 3 to move. The collar 4 will fix the position of the brush 5, and when the collar 4 moves, it will drive the brush 5 to move.

[0025] A limit disk 6 is threadedly connected inside the screw body 1, and an anti-slip block 7 is connected to the outer surface of the limit disk 6. The limit disk 6 can be placed inside the screw body 1 by rotation, and the connection method of the thread makes the limit disk 6 unable to be directly pulled out of the screw body 1. The limit disk 6 will fix the position of the anti-slip block 7, and the anti-slip block 7 can facilitate the rotation of the limit disk 6. When the user rotates the anti-slip block 7, the anti-slip block 7 will drive the limit disk 6 to rotate.

[0026] A cross bar 8 is connected to the outer surface of the limit disk 6, and a spring 9 is connected inside the cross bar 8. The limit disk 6 will fix the position of the cross bar 8, and when the limit disk 6 moves, it will drive the cross bar 8 to move. The cross bar 8 will limit the position of the spring 9.

[0027] The output end of the spring 9 is connected to the limit block 10, and the outer surface of the cross bar 8 is connected to the limit rod 11. The spring 9 can provide a thrust to the limit block 10, so that when the limit block 10 is not affected by other external forces, the spring 9 can push out the limit block 10. The cross bar 8 will fix the position of the limit rod 11 and drive the limit rod 11 to move when the cross bar 8 moves.

[0028] The inside of the screw body 1 is connected with a support rod 12, and the outer surface of the support rod 12 is rotatably connected with an adjusting plate 13. The screw body 1 will limit the position of the support rod 12 to prevent the support rod 12 from moving. The support rod 12 can provide support for the adjusting plate 13 to enable the adjusting plate 13 to rotate around the support rod 12.

[0029] The outer surface of the adjusting plate 13 is slidably connected to the inside of the screw body 1, and the upper surface of the adjusting plate 13 is connected with an adjusting block 14. The screw body 1 will limit the position of the adjusting plate 13 to prevent the adjusting plate 13 from moving horizontally. The adjusting plate 13 will fix the position of the adjusting block 14, and the user can move the adjusting plate 13 by moving the position of the adjusting block 14.

[0030] A barrier block 15 is clamped inside the screw body 1, and an insertion block 16 is connected inside the barrier block 15. The outer surface of the insertion block 16 is slidably connected to the inside of the adjusting plate 13. When the barrier block 15 is inserted into the screw body 1, the screw body 1 will limit the position of the barrier block 15, and the barrier block 15 will fix the position of the insertion block 16. When the barrier block 15 moves, it will drive the insertion block 16 to move. The insertion block 16 can be inserted into the inside of the adjusting plate 13. When the insertion block 16 is inserted into the inside of the adjusting plate 13, the adjusting plate 13 cannot rotate.

[0031] The outer surface of the clamping plate 3 is slidably connected to the inside of the barrier block 15, and the outer surface of the collar 4 is in contact with the outer surface of the barrier block 15. The clamping plate 3 will pass through the barrier block 15 and insert into the screw body 1.

[0032] The outer surface of the brush 5 is slidably connected to the outer surface of the screw body 1, the outer surface of the anti-sliding block 7 is slidably connected to the inside of the screw body 1, and the outer surface of the cross bar 8 is slidably connected to the inside of the screw body 1. When the brush 5 moves, it can clean out the fine impurities inside the screw body 1. The inside of the collar 4 will be in contact with the outer surface of the screw body 1. When the collar 4 drives the brush 5 to move, the brush 5 will not shake. The screw body 1 will limit the position of the anti-sliding block 7 to prevent the position where the anti-sliding block 7 moves from deviating, and the screw body 1 will limit the direction in which the cross bar 8 can move.

[0033] The outer surface of the limit block 10 is slidably connected to the inside of the cross bar 8, the outer surface of the limit block 10 is slidably connected to the inner side wall of the chute 2, the outer surface of the limit rod 11 is slidably connected to the inside of the limit block 10, and the limit rod 11 restricts the direction in which the limit block 10 can move, so that the position where the limit block 10 moves will not deviate, and the chute 2 restricts the position where the limit block 10 can move.

[0034] Working principle: When using this device, first rotate to pull out the collar 4 with the clamping plate 3 from the screw body 1, then rotate the collar 4 to remove the screw body 1. Then rotate the anti-slip block 7 to pull out the limit disc 6 from the screw body 1. The movement of the limit disc 6 will drive the cross bar 8 to move. After moving the cross bar 8 to a position where one end of the limit block 10 is in contact with the chute 2, the user can hold the cross bar 8 with the palm of the hand and press the thumb against one end of the screw body 1 to move it to the other end and press it against the machine to be connected. Then the user moves the blocking block 15 away and pulls out the adjusting plate 13. Then rotate the adjusting plate 13 to install the screw body 1 in the machine to be connected.
