Description

Technical Field

[0001] The utility model belongs to the technical field of double-ended threaded rods, in particular to a double-ended threaded rod which is easy to install. Background Art

[0002] Double-ended threaded rods are a type of connection element widely used in machinery, construction, and other fields. They are usually used to connect two or more components. Their unique design gives them superior performance and convenience in specific applications. With the acceleration of industrialization and modernization, the market demand for connection elements continues to increase, especially for products that are easy to install and disassemble.

[0003] Among the traditional connection methods, common threaded connection, welding and gluing methods can meet certain needs, but they often have problems such as complex installation, difficult disassembly, and time-consuming. The double-ended threaded rod perfectly solves this problem. It can achieve quick connection through a simple rotation operation, greatly reducing installation time.

[0004] However, there are still some problems in the actual use of this device. For example, in actual use, since the diameter of the double-ended tooth bar itself is fixed, various sizes need to be matched with it when it is actually inserted, which is inconvenient to use. A single double-ended tooth bar cannot penetrate holes of different diameters, which results in the inability to perfectly match the hole in actual use.

[0005] Therefore, in order to solve the above problems, a double-ended toothed rod which is easy to install is proposed. Utility Model Content

[0006] In order to make up for the shortcomings of the existing technology and solve the problem that various sizes need to be matched during insertion, which is inconvenient to use, a single double-ended tooth rod cannot be integrated to pass through holes of different calibers, which leads to the problem that it cannot be perfectly matched with the holes during actual use. A double-ended tooth rod that is easy to install is proposed.

[0007] The technical solution adopted by the present invention to solve its technical problems is: the double-headed tooth bar that is easy to install described in the present invention comprises a supporting outer rod, the inner wall of the supporting outer rod is movably connected with a movable ball rod, the surface of the movable ball rod is fixedly connected with a supporting shaft rod, the interior of the supporting outer rod is movably connected with a rotating inner rod, the surface of the rotating inner rod is clamped with a clamping plate, the side of the clamping plate away from the rotating inner rod is movably connected with one end of the supporting shaft rod, the surface of the rotating inner rod is provided with an interlocking positioning groove, the interior of the rotating inner rod is movably connected with a rotating inner sleeve, both ends of the rotating inner sleeve are provided with positioning rings, and the side of the positioning ring close to the rotating inner sleeve is provided with an abutting positioning groove.

[0008] Preferably, the abutment positioning groove is opened in a circular array, and protrusions matching the abutment positioning groove are provided at both ends of the top support outer rod. The protrusions are used to fix the positioning ring and the abutment positioning groove in rotation, ensuring the fixing effect of the abutment positioning groove.

[0009] Preferably, the supporting shaft is connected to the inside of the interlocking positioning groove, and the side of the clamping plate close to the rotating inner rod is engaged with the surface of the rotating inner sleeve. The interlocking positioning groove is used to limit the moving direction of the supporting shaft, thereby ensuring the supporting strength of the supporting shaft and preventing it from breaking due to improper force.

[0010] Preferably, the positioning ring is a pull-out structure design, the length of the rotating inner rod is smaller than the length of the rotating inner sleeve, the positioning ring is used to rotate the angular direction of the rotating inner sleeve, the surface of the rotating inner sleeve is provided with a latching tooth, and the side of the clamping plate close to the rotating inner rod is provided with a tooth groove matching the latching tooth, thereby avoiding the outer rod being able to be reset when the rotating inner sleeve is fixed.

[0011] Preferably, a clip strip is provided at the end of the rotating inner sleeve, and a long groove formed by a matching clip strip is provided on the side of the positioning ring close to the rotating inner sleeve. The positioning ring is fixedly connected to the rotating inner sleeve through the long groove engaging clip strip, thereby ensuring that the positioning ring can drive the rotating inner sleeve to rotate simultaneously during the rotation process.

[0012] Preferably, the width of the protrusion on the surface of the top support outer rod that matches the positioning groove is smaller than the opening width of the positioning groove, and the height of the protrusion on the surface of the top support outer rod that matches the positioning groove is greater than the opening depth of the positioning groove, thereby improving the installation convenience of the positioning ring.

[0013] Beneficial effects of the utility model:

[0014] The utility model provides a double-ended toothed rod which is easy to install. By arranging related mechanisms such as a rotating inner rod and a supporting shaft rod, the supporting outer rod is layered as a whole, so that the supporting outer rod can fine-tune its own diameter so that it can completely fit into a hole which is slightly larger or slightly smaller than the original diameter during the process of connecting with the connecting piece, thereby avoiding the problem that the existing supporting outer rod is prone to shaking when inserted into the hole groove.

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Specific examples are given below.

[0023] See also Figure 1-3 The utility model provides a double-ended tooth bar that is easy to install, comprising a supporting outer rod 1, the inner wall of the supporting outer rod 1 is movably connected with a movable ball rod 2, the surface of the movable ball rod 2 is fixedly connected with a supporting shaft rod 3, the interior of the supporting outer rod 1 is movably connected with a rotating inner rod 5, the surface of the rotating inner rod 5 is clamped with a clamping plate 4, the side of the clamping plate 4 away from the rotating inner rod 5 is movably connected to one end of the supporting shaft rod 3, the surface of the rotating inner rod 5 is provided with an engaging positioning groove 6, the interior of the rotating inner rod 5 is movably connected with a rotating inner sleeve 7, both ends of the rotating inner sleeve 7 are provided with positioning rings 8, and the side of the positioning ring 8 close to the rotating inner sleeve 7 is provided with an abutting positioning groove 9.

[0024] In this embodiment, the device needs to rotate the positioning ring 8 during use, thereby driving the rotating inner sleeve 7 to rotate at the same time. During the rotation of the rotating inner sleeve 7, it can be found that the rotating inner sleeve 7 can effectively drive the card plate 4 engaged thereon to move, and during the movement of the card plate 4, the spacing between the rotating inner sleeve 7 and the supporting outer rod 1 is increased to support the supporting outer rod 1 through the supporting shaft rod 3. During this process, the movable ball rod 2 moves inside the supporting outer rod 1 to support the supporting outer rod 1, thereby ensuring that the supporting outer rod 1 can fine-tune its own diameter by rotating the rotating inner sleeve 7, thereby effectively ensuring that there will be no gap between it and the hole that needs to be plugged in.

[0025] Reference Figure 1-3 Among them, the abutment positioning groove 9 is opened in a circular array, and protrusions matching the abutment positioning groove 9 are provided at both ends of the top support outer rod 1. The protrusions are used to fix the positioning ring 8 and the abutment positioning groove 9 to rotate.

[0026] In this embodiment, through such an arrangement, the abutting positioning groove 9 is opened in a circular array to match the protrusions on the surface of the top support outer rod 1 for fixing. During the fixing process, since the size of the abutting positioning groove 9 itself is larger than the size of the protrusions on the surface of the top support outer rod 1, the abutting positioning groove 9 can still fix the top support outer rod 1 even if there is an offset, thereby ensuring the fixing effect of the abutting positioning groove 9.

[0027] Reference Figure 1-3 Among them, the supporting shaft rod 3 passes through and is connected to the inside of the interlocking positioning groove 6, and the side of the clamping plate 4 close to the rotating inner rod 5 is engaged with the surface of the rotating inner sleeve 7, and the interlocking positioning groove 6 is used to limit the moving direction of the supporting shaft rod 3.

[0028] In this embodiment, such an arrangement ensures that the movable direction of the supporting shaft 3 can be fixed by the clamping plate 4 during the use of the device, and the supporting shaft 3 is also clamped by the clamping plate 4 during the process of engaging the clamping plate 4 in the positioning groove 6, thereby ensuring the use effect of the device.

[0029] Reference Figure 1-3 Among them, the positioning ring 8 is a pull-out structure design, the length of the rotating inner rod 5 is smaller than the length of the rotating inner sleeve 7, the positioning ring 8 is used to rotate the angular direction of the rotating inner sleeve 7, the surface of the rotating inner sleeve 7 is provided with a latch tooth, and the side of the clamping plate 4 close to the rotating inner rod 5 is provided with a tooth groove matching the latch tooth.

[0030] In this embodiment, by such an arrangement, the device can effectively ensure that the positioning ring 8 can fix the rotating inner sleeve 7, the rotating inner rod 5 and the supporting outer rod 1 during use, thereby ensuring the use effect of the device.

[0031] Reference Figure 1-3 Among them, a clamping strip is provided at the end of the rotating inner sleeve 7, and a long groove opened by a matching clamping strip is provided on the side of the positioning ring 8 close to the rotating inner sleeve 7. The positioning ring 8 is fixedly connected to the rotating inner sleeve 7 by engaging the clamping strip through the long groove.

[0032] In this embodiment, such an arrangement ensures that the device can be matched and fixed with the positioning ring 8 during use, so that the positioning ring 8 can drive the rotating inner sleeve 7 to rotate at the same time when it rotates. It should also be noted that when the positioning ring 8 and the supporting outer rod 1 are fixed, it is necessary to first pull it outward from the limit of the rotating inner rod 5 for a distance, and then match it with the supporting outer rod 1 for engagement and fixation.

[0033] Reference Figure 1-3 Among them, the width of the protrusion on the surface of the top support outer rod 1 that matches the positioning groove 9 is smaller than the opening width of the positioning groove 9, and the height of the protrusion on the surface of the top support outer rod 1 that matches the positioning groove 9 is greater than the opening depth of the positioning groove 9.

[0034] In this embodiment, by such an arrangement, during use of the device, even if the installation positions of the positioning ring 8 and the supporting outer rod 1 do not completely coincide, the supporting outer rod 1 can still be effectively engaged and fixed.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
