Description

Technical Field

[0001] This utility model belongs to the field of bolt threaded rod technology, and in particular relates to a corrosion-resistant threaded rod. Background Technology

[0002] Bolt: A mechanical part, a cylindrical threaded fastener used with a nut. It is a type of fastener consisting of a head and a shank (a cylinder with external threads), which needs to be used with a nut to fasten two parts with through holes. The threaded shank of the bolt is also called a threaded rod.

[0003] The existing bolts and threaded rods are generally integrated, so when installing parts of different thicknesses (such as chassis fans of different thicknesses), bolts of different lengths are required for fixing, thus reducing the applicable range of bolts. Utility Model Content

[0004] This invention provides a corrosion-resistant threaded rod, aiming to solve the problem that existing bolts and threaded rods are generally integrated, thus requiring bolts of different lengths for fixing parts of different thicknesses (such as chassis fans of different thicknesses), thereby reducing the applicable range of bolts.

[0005] This utility model is implemented as follows: a corrosion-resistant toothed strip includes a first connecting frame and a second connecting frame. Both the first and second connecting frames are U-shaped and are staggered. The first and second connecting frames are slidably connected. One side of the first connecting frame has an end, and the toothed strip is fixedly connected to one side of the second connecting frame. An adjustment mechanism is provided between the first and second connecting frames to adjust the distance between the toothed strip and the end.

[0006] The adjusting mechanism includes a threaded sleeve and a rotating rod, with the end of the threaded sleeve fixedly connected to the second connecting frame.

[0007] The rotating rod is disposed through the middle of the first connecting frame, the rotating rod is rotatably connected to the first connecting frame, the outer circumference of the rotating rod is provided with threads, one end of the rotating rod is fixedly connected to the end, the other end of the rotating rod is threadedly connected to the threaded sleeve, and a locking structure is provided between the first connecting frame and the rotating rod;

[0008] By rotating the end relative to the first connecting frame, the rotating rod can be driven to rotate relative to the first connecting frame. Since the rotating rod is threadedly connected to the threaded sleeve, and the second connecting frame, which is fixedly connected to the threaded sleeve, cannot rotate relative to the first connecting frame, the rotating rod can drive the threaded sleeve to move around the outer circumference of the rotating rod when it rotates. At the same time, the threaded sleeve will drive the second connecting frame to move relative to the first connecting frame. Therefore, by adjusting the rotation direction of the end, the distance between the first and second connecting frames can be adjusted, thereby adjusting the distance between the end and the toothed bar, and thus adjusting the overall length of the device.

[0009] Preferably, the locking structure includes a locking groove and a recess, the locking groove is formed on the outer periphery of the rotating rod, and the number of locking grooves is set to multiple, with the multiple locking grooves distributed around the center of the rotating rod;

[0010] The groove is formed on the surface of the first connecting frame, and a fixing bolt is threadedly connected to the middle of the groove;

[0011] Once the distance between the end and the toothed bar is appropriate, the end of the fixing bolt can be inserted into the locking groove on the outer circumference of the rotating rod by rotating the fixing bolt, thereby locking the rotating rod. At this time, the rotating rod and the end cannot rotate relative to the first moving frame, thus locking the distance between the end and the toothed bar. At this time, rotating the end can drive the toothed bar to rotate synchronously.

[0012] Preferably, the surface of the toothed bar is provided with an electroplated layer, which is made of zinc;

[0013] Applying an electroplating layer to the surface of the feed bar can improve its corrosion resistance, thus preventing it from corroding in humid environments.

[0014] Preferably, the end of the fixing bolt is chamfered, and the end of the fixing bolt matches a plurality of locking grooves;

[0015] By setting a chamfer at the end of the fixing bolt, the end of the fixing bolt can be easily inserted into the locking groove on the outer circumference of the rotating rod.

[0016] Preferably, a washer is provided on one side of the end, and the surface of the washer is provided with anti-slip texture;

[0017] By using washers, when the device is installed inside a fixed object, noise caused by vibration between the device and the fixed object can be prevented when the installed object vibrates.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] By coordinating the adjustment mechanism and the locking mechanism, the distance between the end of the device and the toothed bar can be adjusted, thereby adjusting the length of the device. This allows the device to be adjusted to fit the thickness of the object to be fixed, thus improving its applicability. Attached Figure Description

[0033] Please see Figure 1-3 This utility model provides a technical solution: a corrosion-resistant toothed strip, including a first connecting frame 1 and a second connecting frame 11, both the first connecting frame 1 and the second connecting frame 11 are U-shaped, the first connecting frame 1 and the second connecting frame 11 are staggered and slidably connected, the first connecting frame 1 and the second connecting frame 11 are provided with an end 12 on one side, and a toothed strip 13 is fixedly connected to one side of the second connecting frame 11. An adjustment mechanism 2 is provided between the first connecting frame 1 and the second connecting frame 11, the adjustment mechanism 2 is used to adjust the distance between the toothed strip 13 and the end 12;

[0034] The adjusting mechanism 2 includes a threaded sleeve 21 and a rotating rod 22, with the end 12 of the threaded sleeve 21 fixedly connected to the second connecting frame 11;

[0035] The rotating rod 22 is installed through the first connecting frame 1 in the middle. The rotating rod 22 is rotatably connected to the first connecting frame 1. The outer circumference of the rotating rod 22 is threaded. One end of the rotating rod 22 is fixedly connected to the end 12, and the other end of the rotating rod 22 is threadedly connected to the threaded sleeve 21. A locking structure 23 is provided between the first connecting frame 1 and the rotating rod 22.

[0036] Furthermore, the locking structure 23 includes a locking groove 231 and a recess 232. The locking groove 231 is formed on the outer periphery of the rotating rod 22. The number of locking grooves 231 is set to multiple, and the multiple locking grooves 231 are distributed around the center of the rotating rod 22.

[0037] A groove 232 is formed on the surface of the first connecting frame 1, and a fixing bolt 233 is threadedly connected to the middle of the groove 232.

[0038] Furthermore, the surface of the toothed rod 13 is provided with an electroplated layer 3, which is made of zinc.

[0039] Furthermore, the end 12 of the fixing bolt 233 is chamfered, and the end 12 of the fixing bolt 233 matches the multiple locking grooves 231.

[0040] Furthermore, a washer 4 is provided on one side of the end 12, and the surface of the washer 4 is provided with anti-slip texture 5.

[0041] The working principle and usage process of this utility model: After the utility model is installed, by rotating the end 12 relative to the first connecting frame 1, the rotating rod 22 can be rotated relative to the first connecting frame 1. Because the rotating rod 22 is threadedly connected to the threaded sleeve 21, and the second connecting frame 11, which is fixedly connected to the threaded sleeve 21, cannot rotate relative to the first connecting frame 1, the rotating rod 22 can drive the threaded sleeve 21 to move around the outer periphery of the rotating rod 22. At the same time, the threaded sleeve 21 will drive the second connecting frame 11 to move relative to the first connecting frame 1. Therefore, by adjusting the rotation direction of the end 12, the distance between the first connecting frame 1 and the second connecting frame 11 can be adjusted, thereby adjusting the distance between the end 12 and the toothed bar 13, and thus adjusting the overall length of the device.

[0042] When the distance between end 12 and toothed rod 13 is appropriate, the end 12 of the fixing bolt 233 can be inserted into the locking groove 231 on the outer periphery of the rotating rod 22 by rotating the fixing bolt 233, thereby locking the rotating rod 22. At this time, the rotating rod 22 and end 12 cannot rotate relative to the first moving frame, thereby locking the distance between end 12 and toothed rod 13. At this time, rotating end 12 can drive toothed rod 13 to rotate synchronously.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
