Description

Technical Field

[0001] The utility model belongs to the technical field of pull ring equipment, in particular to a novel pull ring with self-damping. Background Art

[0002] With the advancement of science and technology in modern society, the development of the automobile industry is also becoming more and more rapid. Especially in the aspect of automobile accessories, people pay more attention to the design of details. The trunk of a car is one of the automobile accessories. At present, common cars all have a trunk for placing various items. When needed, the trunk lid can be opened to take and put items in the trunk, which is very convenient. Nowadays, the trunk space of cars is relatively large, but many times, people will put relatively small things in the trunk. The objects in the trunk of the car are running around in the box, which is messy and the noise is too loud, which affects driving and judging the running status of the car. Therefore, a hanging ring is set in the trunk of the car.

[0003] For example, the Chinese patent automobile D-type pull ring, application number 201210502486.X, includes a base, a torsion spring, a positioning rod and a pull buckle. The base is a round or square base, and a groove is provided in the middle of the base. When the D-type pull ring is not in use, the pull buckle is placed at the notch of the groove due to the torsion of the torsion spring to prevent the pull buckle from moving around and being unfavorable for use. However, the automobile D-type pull ring uses the torsion spring to reset the pull buckle, and during use, the pull ring cannot be kept in one position for a long time under the action of the torsion spring. The user needs to control the position of the pull ring and connect the item to the hanging ring at the same time, which is inconvenient for the user to use. Utility Model Content

[0004] In view of this, the utility model provides a novel self-damping pull ring which can realize rotation adjustment and fixation at any position to meet industrial needs.

[0005] A new type of self-damping pull ring includes a pull ring base, a rotating shaft arranged on the pull ring base, and a pull ring fixedly connected to the rotating shaft. The pull ring base includes a base body, a mounting frame arranged on the base body and used to accommodate the rotating shaft, and two elastic clamping frames symmetrically arranged on the base body. The mounting frame includes a mounting frame body fixedly connected to a side edge of the base body, and a mounting hole arranged on the mounting frame body. Each of the elastic clamping frames includes a clamping frame body and an arc-shaped clamping head arranged at one end of the clamping frame body. The rotating shaft includes a rotating shaft body inserted into the mounting hole, and at least one pull ring mounting section arranged at one end of the rotating shaft body and fixedly connected to the pull ring. During the assembly process, the arc-shaped clamping head is obliquely arranged on the side of the mounting frame facing away from the pull ring base. When assembled, the arc-shaped clamping head coincides with the central axis of the mounting hole, the rotating shaft body is accommodated in the mounting hole, and the pull ring mounting section is fixedly connected to the pull ring.

[0006] Furthermore, the pull ring base also includes a plurality of limit baffles arranged at the bottom of the base body, and a protective cover limit baffle arranged on one side of the base body.

[0007] Furthermore, the limit baffle includes a limit baffle body and an elastic protrusion arranged on a side wall of the limit baffle body.

[0008] Furthermore, the novel self-damping pull ring also includes a protective cover sleeved on the pull ring base. When the protective cover and the pull ring base are assembled together, the protective cover limit baffle is clamped on the inner wall of the protective cover.

[0009] Furthermore, the pull ring base also includes a screw rod screwed onto the base body.

[0010] Furthermore, the pull ring includes a pull ring body and two pull ring mounting holes arranged on the pull ring body, and the pull ring mounting section and the pull ring mounting holes are spline-connected.

[0011] Furthermore, when the pull ring is installed on the rotating shaft, the pull ring and the side wall of the base body on the opposite side are parallel to each other.

[0012] Compared with the prior art, the new self-damping pull ring provided by the utility model fixes the rotating shaft through the mounting frame and the elastic clamping frame in the pull ring base, and forms a damping feeling between the rotating shaft, the mounting hole, and the elastic clamping frame. The mounting frame includes a mounting frame body fixedly connected to the edge of one side of the base body, and a mounting hole set on the mounting frame body. The elastic clamping frame includes a clamping frame body and an arc-shaped clamping head set at one end of the clamping frame body. During the assembly process, the arc-shaped chuck is tilted on the side of the mounting frame facing away from the pull ring base. When assembled, the arc-shaped chuck coincides with the central axis of the mounting hole, the rotating shaft body is accommodated in the mounting hole, and the pull ring mounting section is fixedly connected to the pull ring, so that the pull ring drives the rotating shaft to rotate. When assembled, the elastic clamping frame is deformed, and the elastic clamping frame applies pressure to the rotating shaft body, so that the mounting hole and the arc-shaped chuck are tightly fitted together with the rotating shaft, so that damping is formed between the elastic clamping frame, the mounting frame and the rotating shaft body. It can be seen from this that the new self-damping pull ring has a simple structure, is easy to assemble, improves the damping sense between the rotating shaft and the pull ring base, and realizes the rotation fixation of the pull ring at any position.

[0017] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0018] like Figures 1 to 4As shown, it is a schematic diagram of the structure of the new self-damping pull ring provided by the utility model. The new self-damping pull ring includes a pull ring base 10, a rotating shaft 20 arranged on the pull ring base 10, a pull ring 30 fixedly connected to the rotating shaft 20, and a protective cover 40 sleeved on the pull ring base 10. The new self-damping pull ring also includes some other functional modules, such as assembly components, etc., which should be well known to those skilled in the art and will not be described in detail here.

[0019] The pull ring base 10 includes a base body 11, a mounting frame 12 arranged on the base body 11, and two elastic clamping frames 13 symmetrically arranged on the base body 11, a plurality of limit baffles 14 arranged at the bottom of the base body 11, a protective cover limit baffle 15 arranged on one side of the base body 11, and a screw 16 screwed to the base body 11.

[0020] The base body 11 is used to be fixed to the mounting device. The base body 11, the mounting frame 12, and the elastic clamping frame 13 are all existing technologies and will not be described in detail. The base body 11, the mounting frame 12, and the elastic clamping frame 13 are all integrally formed to ensure the structural stability of the pull ring base 10. The mounting frame 12 and the elastic clamping frame 13 are both inclined.

[0021] The mounting frame 12 includes a mounting frame body 121 fixedly connected to a side edge of the base body 11 , and a mounting hole 122 disposed on the mounting frame body 121 .

[0022] Each of the elastic clamping frames 13 includes a clamping frame body 131 and an arc-shaped clamping head 132 disposed at one end of the clamping frame body 131 .

[0023] The arc-shaped clamp 132 is used to fix the rotating shaft 20 , and the arc-shaped clamp 132 will be described in detail in conjunction with the rotating shaft 20 .

[0024] The limit baffle 14 is disposed at the bottom of the base body 11. The limit baffle 14 is used to guide and limit the installation position of the base body 11. The limit baffle 14 includes a limit baffle body 141 and an elastic protrusion 142 disposed on the side wall of the limit baffle body 141. When the pull ring base 10 is installed in the installation hole of the installation device, the limit baffle 14 is inserted into the installation hole, and one end of the elastic protrusion 142 abuts against the edge of the installation hole to limit the position of the pull ring base 10 in the installation hole of the installation device, so as to realize the rapid installation of the pull ring base 10.

[0025] The protective cover limiting baffle 15 is used to limit the protective cover 40, and the screw 16 fixes the base body 11 to other devices. The limiting baffle 14, the protective cover limiting baffle 15, and the screw 16 are all existing technologies.

[0026] The rotating shaft 20 includes a rotating shaft body 21 inserted into the mounting hole 122, and at least one pull ring mounting section 22 disposed at one end of the rotating shaft body 21 and fixedly connected to the pull ring 30. The rotating shaft body 21 and the pull ring mounting section 22 are integrally formed to ensure the structural stability of the rotating shaft 20. The rotating shaft body 21 is accommodated in the mounting hole 122 and the arc-shaped clamp 132, and the rotating shaft 20 can rotate in the mounting hole 122 and the arc-shaped clamp 132. The pull ring mounting section 22 is used to connect the pull ring 30, and the pull ring 30 is fixedly connected to the rotating shaft 20.

[0027] The pull ring 30 includes a pull ring body 31 and two pull ring mounting holes 32 arranged on the pull ring body 31. The pull ring mounting section 22 and the pull ring mounting holes 32 are spline-connected to achieve a fixed connection between the pull ring 30, and rotating the pull ring 30 drives the rotating shaft 20 to rotate.

[0028] During the assembly process, the arc-shaped clamp 132 is obliquely arranged on the side of the mounting frame 12 facing away from the pull ring base 10, that is, the arc-shaped clamp 132 is staggered with the central axis of the mounting hole 122. During assembly, the arc-shaped clamp 132 coincides with the central axis of the mounting hole 122, the rotating shaft body 21 is accommodated in the mounting hole 122, the pull ring mounting section 22 is fixedly connected to the arc-shaped clamp 132, and the pull ring mounting section 22 is fixedly connected to the pull ring 30, that is, during the assembly process, the elastic clamping frame 13 is deformed so that the arc-shaped clamp 132 coincides with the mounting frame 12, and the elastic clamping frame 13 uses its own elasticity to apply force to the rotating shaft 20, and because the arc-shaped clamp 132 is obliquely arranged, that is, the elastic clamping frame 13 uses its own elasticity to apply a force to the rotating shaft 20 as an inclined force, thereby tilting and pressing down the rotating shaft 20, so that the rotating shaft 20 abuts against one side of the mounting hole 122. When the pull ring 30 is installed on the rotating shaft 20 , the pull ring 30 and the side wall of the base body 11 on the opposite side are parallel to each other, so that the pull ring 30 and the base body 11 are aligned, and this position is the initial position of the pull ring 30 .

[0029] When the pull ring 30 is rotated, the pull ring 30 drives the rotating shaft 20 to rotate. Due to the restoring elastic force formed by the arc-shaped clamp 132 during the assembly process, the mounting hole 122 and the arc-shaped clamp 132 are tightly fitted together with the rotating shaft 20, so that a damping feeling is formed between the rotating shaft 20 and the arc-shaped clamp 132.

[0030] The protective cover 40 is used to protect the pull ring base 10 . When the protective cover 40 and the pull ring base 10 are assembled together, the protective cover limit baffle 15 is clamped on the inner wall of the protective cover to limit the position of the protective cover 40 on the pull ring base 10 .

[0031] Compared with the prior art, the novel self-damping pull ring provided by the utility model fixes the rotating shaft 20 through the mounting frame 12 and the elastic clamping frame 13 in the pull ring base 10, and forms a damping feeling between the rotating shaft 20, the mounting hole 122, and the elastic clamping frame 13. The mounting frame 12 includes a mounting frame body 121 fixedly connected to the edge of one side of the base body 11, and a mounting hole 122 set on the mounting frame body 121. The elastic clamping frame 13 includes a clamping frame body 131, and an arc-shaped clamping head 132 set at one end of the clamping frame body 131. During the assembly process, the arc-shaped chuck 132 is tiltedly arranged on the side of the mounting frame 12 facing away from the pull ring base 10. When assembled, the arc-shaped chuck 132 coincides with the central axis of the mounting hole 122, the shaft body 21 is accommodated in the mounting hole 122, and the pull ring mounting section 22 is fixedly connected to the pull ring 30, so that the pull ring 30 drives the shaft 20 to rotate. When assembled, the elastic clamping frame 13 is deformed, and the elastic clamping frame 13 applies pressure to the shaft body 21, so that the mounting hole 122 and the arc-shaped chuck 132 are tightly fitted together with the shaft 20, so that damping is formed between the elastic clamping frame 13, the mounting frame 12 and the shaft body 21. It can be seen from this that the new self-damping pull ring has a simple structure and is easy to assemble, which improves the damping sense between the shaft 20 and the pull ring base 10 and realizes the rotation fixation of the pull ring 30 at any position.
