Description

Technical Field

[0001] The utility model relates to the technical field of locomotives, and in particular to a base structure for a fastened locomotive handlebar. Background Art

[0002] The steering rod is an important part of a motorcycle. It connects the handlebars and the body and is responsible for controlling the steering of the vehicle. The design and quality of the steering rod have a crucial impact on the handling and safety of the motorcycle. The base structure is a component for connecting the steering rod. Usually, the base and the steering rod are fixedly connected to ensure that they will not fall off during use.

[0003] In the prior art, the faucet rod and the base are fixedly connected, and the specific method is to insert the faucet rod into the base by extrusion, and then tightly connect the base and the faucet rod by welding. Although this method can quickly connect the faucet rod and the base, when in use, the faucet rod needs to be squeezed between the base before the faucet rod can be fixed on the base. In this process, due to the influence of the squeezing force, the base is easily squeezed by the faucet rod and damaged, affecting the use of the base. Utility Model Content

[0004] The purpose of the utility model is to provide a base structure for a fastened motorcycle steering rod, which solves the problem that the steering rod needs to be squeezed between the base before the steering rod can be fixed on the base. During this process, due to the influence of the squeezing force, the base is easily squeezed by the steering rod and damaged, thus affecting the use of the base.

[0005] The utility model provides the following technical solutions: a base structure for a tightening locomotive handlebar, comprising a base body and a handlebar body, the outer wall of the base body is integrally formed with a side arm frame, the upper top of the side arm frame is provided with a side mounting hole adapted to an external front fork rod, the upper top of the base body is provided with a main mounting hole, and the inside of the main mounting hole is provided with an expansion mechanism for tightening the handlebar body.

[0006] By adopting the above scheme, the faucet rod body and the base body are fixed to each other. During the installation process, the faucet rod body needs to be inserted into the main mounting hole and welded, so as to fix the faucet rod body. In order to avoid the faucet rod body and the base body from falling off before welding, an expansion mechanism is provided to limit the faucet rod body, thereby ensuring that the faucet rod body can maintain a certain stability and avoid falling off to affect welding.

[0007] As a preferred embodiment of the above technical solution, the expansion mechanism includes placement grooves symmetrically opened on the inner wall of the main mounting hole and an expansion member placed in the main mounting hole, the expansion member is composed of an outer protective layer, an inner protective layer and two protective plates, the protective plates are symmetrically vulcanized at the ends of the outer protective layer and the inner protective layer, and a cavity for dispersing pressure is formed at the interval between the outer protective layer and the inner protective layer, and a number of pressurized parts are evenly arranged inside the cavity.

[0008] By adopting the above scheme, after the faucet rod body is inserted into the main mounting hole, the expansion part will be squeezed. At this time, the inner protective layer squeezes the pressure-bearing part, and the pressure-bearing part will be compressed due to the squeezing force and dispersed inside the cavity, thereby transmitting the pressure to the inside of the cavity. As the faucet rod body gradually comes into place, the pressure-bearing part will cause the inner protective layer to be tightly attached to the outer wall of the faucet rod body due to the influence of pressure, thereby playing a tightening role.

[0009] As a preferred embodiment of the above technical solution, a plurality of anti-detachment strips for preventing the faucet rod body from detaching are arranged in the inner annular array of the inner protective layer, and only the two ends of the anti-detachment strips are fixedly connected.

[0010] By adopting the above scheme, since only the two ends of the anti-detachment strip are fixedly connected to the inner protective layer, and the middle part of the anti-detachment strip is squeezed on the inner protective layer by the faucet rod body, when the faucet rod body is detached accordingly, the anti-detachment strip will bend and form a wave shape due to the rear pulling force of the faucet rod body, thereby achieving the purpose of preventing the faucet rod body from detaching. As for the forward movement force of the faucet rod body, it will be difficult for the faucet rod body to detach due to the increase in friction.

[0011] As a preferred embodiment of the above technical solution, the expansion member is fixedly connected to the inside of the placement groove through a guard plate.

[0012] By adopting the above scheme, the expansion piece can be restricted in the main installation hole by fixing the guard plate of the expansion piece inside the placement groove. At the same time, the setting of the guard plate can facilitate the installation and disassembly of the expansion piece, thereby achieving the purpose of quick disassembly and assembly.

[0013] As a preferred embodiment of the above technical solution, the faucet rod body is divided into an upper end and a lower end, the lower end of the faucet rod body is inserted into the interior of the main mounting hole, and the end size ratio of the upper end and the lower end is 1 to 1.5.

[0014] By adopting the above scheme, the lower end of the faucet rod body is inserted into the interior of the installation hole. After the installation is completed, the base body and the lower end of the faucet rod body can be quickly welded. At the same time, the size of the lower end is wider, which can quickly exert pressure on the expansion piece.

[0015] As a preferred embodiment of the above technical solution, the center points of the main mounting hole, the faucet rod body and the expansion member are all at the same position.

[0016] By adopting the above solution, to a certain extent, the three are at the same center of the circle, which can ensure stability during the installation process and avoid installation problems due to errors.

[0017] As a preferred embodiment of the above technical solution, the expansion member is made entirely of rubber material, and the guard plate is made of metal material.

[0018] With the above scheme, the expansion piece is made of rubber material, and the rubber material has a certain elastic change, and will not be seriously damaged due to extrusion force or tension during use, so as to extend the service life of the device. The guard plate is made of metal material, which can ensure a close connection between the guard plate and the placement groove, and avoid the guard plate from being separated from the placement groove due to external force during use.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] In the utility model, an expansion mechanism is provided. When the faucet rod body is inserted into the main mounting hole, the expansion mechanism will expand by being squeezed, so that the expansion mechanism can wrap the faucet rod body. At this time, the squeezing force of the faucet rod body is applied to the expansion mechanism, and the expansion mechanism will expand by itself, thereby avoiding the squeezing force of the faucet rod body from being applied to the base body, so as to ensure that the base body will not be damaged by the squeezing force. At the same time, different models of faucet rod bodies can be assembled through the expansion mechanism, and a certain tightening effect can be provided. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a base structure for a fastening locomotive steering rod, comprising a base body 1 and a steering rod body 2, the outer wall of the base body 1 is integrally formed with a side arm frame 11, the upper top of the side arm frame 11 is provided with a side mounting hole 12 adapted to the external front fork rod, the upper top of the base body 1 is provided with a main mounting hole 13, the inside of the main mounting hole 13 is provided with an expansion mechanism for fastening the steering rod body 2, so as to stabilize the steering rod body 2 before welding.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the expansion mechanism includes a placement groove 14 symmetrically opened on the inner wall of the main installation hole 13 and an expansion member 3 placed in the main installation hole 13. The expansion member 3 is composed of an outer protective layer 32, an inner protective layer 35 and two protective plates 31. The protective plates 31 are symmetrically vulcanized at the ends of the outer protective layer 32 and the inner protective layer 35. The vulcanization makes the connection between the protective plates 31 and the expansion member 3 tighter. The expansion member 3 is fixedly connected to the inside of the placement groove 14 through the protective plates 31 to fix the expansion member 3 in the main installation hole 13. The interval between the outer protective layer 32 and the inner protective layer 35 is A cavity 33 for dispersing pressure is formed, and a plurality of pressure-bearing parts 34 are evenly arranged inside the cavity 33. After being squeezed, the pressure-bearing parts 34 disperse the pressure in the cavity 33. The inner annular array of the inner protective layer 35 is provided with a plurality of anti-detachment strips 36 for preventing the faucet rod body 2 from detaching, and only the two ends of the anti-detachment strips 36 are fixedly connected. The anti-detachment strips 36 are in contact with the outer wall of the faucet rod body 2. When the faucet rod body 2 wants to detach, the middle part of the anti-detachment strip 36 forms a wave shape due to the pulling force, thereby preventing the faucet rod body 2 from detaching.

[0029] like Figure 1 and Figure 4As shown, the faucet rod body 2 is divided into an upper end 21 and a lower end 22. The lower end 22 of the faucet rod body 2 is inserted into the main mounting hole 13, so that the faucet rod body 2 can be installed more quickly and welding work can be performed. The end size ratio of the upper end 21 and the lower end 22 is 1 to 1.5. The center points of the main mounting hole 13, the faucet rod body 2 and the expansion piece 3 are all in the same position. The expansion piece 3 is made of rubber material as a whole. The rubber material has good ductility, so that it can better withstand pressure and work, and the guard plate 31 is made of metal material.

[0030] Working principle: when in use, insert the faucet rod body 2 into the main mounting hole 13, at which time the faucet rod body 2 will squeeze the expansion member 3, and due to the setting of the internal cavity 33 of the expansion member 3, when the expansion member 3 is squeezed, the pressure-bearing member 34 can disperse the pressure to avoid the pressure being concentrated in one place, and at this time, after the faucet rod body 2 squeezes the expansion member 3, the inner protective layer 35 contacts the outer wall of the faucet rod body 2, thereby achieving a wrapping effect, and at the same time, due to the squeezing of the expansion member 3 by the faucet rod body 2, the anti-slip strip 36 will be in an extruded state, and since the anti-slip strip 36 and The inner protective layer 35 is not fully fitted. When the faucet rod body 2 wants to fall off, the extrusion force generated will be applied to the faucet rod body 2, thereby achieving the purpose of preventing the faucet rod body 2 from falling off. When the end of the faucet rod body 2 is parallel to the end of the base body 1, the staff can weld the parallel surfaces to make the connection between the faucet rod body 2 and the base body 1 tighter. Through the setting of the expansion mechanism, different models of faucet rod bodies 2 can be assembled quickly and provide a certain tightening effect, thereby achieving the purpose of bearing greater loads and impacts.

[0031] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
