[0002] The limiting ring of the automobile seat headrest rod is a device located on the headrest rod, which is used to limit the movement range of the headrest, such as the extreme positions when adjusting the height or moving forward and backward. The limiting ring can ensure that the headrest remains stable after being adjusted to a suitable position. For example, in a rear-end collision or other accident of the vehicle, the headrest can accurately be in the best position to protect the head and neck of the driver and passengers, play a buffering role, prevent the head from tilting backward or shifting excessively, and reduce the risk of neck injury.
[0003] In the prior art, after the headrest rod is installed, a guide groove for the sliding of the guide block is opened on the headrest rod, and a plurality of limiting grooves for restricting the up and down movement of the limiting ring are opened. However, in the prior art, the product of the limiting ring adopts a limiting structure composed of a plurality of scattered parts such as springs, buttons and limiting rods to realize the installation and disassembly of the headrest. Due to the large number of scattered parts, the production cost is relatively high, and due to the excessive number of parts, the parts are easily damaged during the frequent operation of moving the limiting ring up and down, affecting the service life. Summary of the Utility Model
[0004] The utility model provides a new type of integrated seat headrest rod limiting ring for automobiles, which is beneficial to reducing the overall production cost of the limiting ring and reducing the damage of parts.
[0005] In order to solve the problems of the prior art, the utility model discloses a new type of integrated seat headrest rod limiting ring for automobiles, which comprises a limiting ring body.
[0006] An activity groove is opened in the middle of the front end of the limiting ring body. A limiting rod is arranged in the activity groove. The limiting rod extends into the limiting ring body through the activity groove. A left arc-shaped elastic rod is fixed at the left end of the limiting rod. An arc-shaped fixing rod is fixed at the rear end of the left arc-shaped elastic rod. A U-shaped handle is arranged at the right end of the limiting rod. A right arc-shaped elastic rod is connected between one end of the U-shaped handle and the right end of the limiting rod. An elastic clamping rod is connected to the other end of the U-shaped handle. A limiting block for abutting against the elastic clamping rod is fixed on the right side of the limiting ring body. The limiting rod, the left arc-shaped elastic rod, the right arc-shaped elastic rod, the arc-shaped fixing rod, the U-shaped handle and the elastic clamping rod are integrally formed.
[0007] Furthermore, a left limiting plate is fixed on the left side of the limiting ring body. A left activity port penetrating through the front and back is opened in the left limiting plate. The arc-shaped fixing rod passes through the left activity port.
[0008] Further, a right limiting plate is fixed to the right side of the limiting ring body. The right limiting plate is located in front of the limiting block, and a right moving port that penetrates through the front and back is formed in the right limiting plate. The other end of the U-shaped handle passes through the right moving port.
[0009] Further, the elastic clamping rod is arc-shaped and bent.
[0010] Further, at least three uniformly distributed guide blocks are connected to the inner wall of the limiting ring body.
[0011] Further, the limiting rod, the left arc-shaped elastic rod, the right arc-shaped elastic rod, the arc-shaped fixing rod, the U-shaped handle and the elastic clamping rod are all made of beryllium copper alloy.
[0012] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:
[0013] 1. When the limiting rod is clamped with the limiting groove on the pillow rod, at this time, the bent part at the front end of the elastic clamping rod abuts against the rear end of the limiting block, which is beneficial to prevent the limiting ring body from sliding up and down along the pillow rod. Moreover, by pulling the U-shaped handle, the limiting rod can be conveniently driven out of the limiting ring body, and thus the limiting rod can be conveniently removed from the limiting groove on the pillow rod. At the same time, the bent part at the rear end of the elastic clamping rod can be conveniently abutted against the front end of the limiting block to prevent the limiting rod from resetting. Therefore, the limiting ring body can be conveniently moved up and down around the pillow rod.
[0014] 2. By integrally forming the limiting rod, the left arc-shaped elastic rod, the right arc-shaped elastic rod, the arc-shaped fixing rod, the U-shaped handle and the elastic clamping rod, and all are made of beryllium copper alloy with good elastic performance, it is not easy to be damaged compared with the prior art, effectively ensuring the service life of the limiting rod, the left arc-shaped elastic rod, the right arc-shaped elastic rod, the arc-shaped fixing rod, the U-shaped handle and the elastic clamping rod. It saves the use of a limiting structure composed of multiple scattered parts to realize the installation and disassembly of the headrest, thereby facilitating the reduction of production costs.

Detailed implementation mode
[0020] A new type of integrated seat headrest rod limiting ring for automobiles:
[0021] As Figures 1-4 shown, in this embodiment, it includes a limiting ring body 1. A movable groove 6 is opened in the middle of the front end of the limiting ring body 1. A limiting rod 8 is arranged in the movable groove 6. The limiting rod 8 extends into the limiting ring body 1 through the movable groove 6. A left arc-shaped elastic rod 13 is fixed at the left end of the limiting rod 8. An arc-shaped fixed rod 9 is fixed at the rear end of the left arc-shaped elastic rod 13. A U-shaped handle 7 is arranged at the right end of the limiting rod 8. A right arc-shaped elastic rod 12 is connected between one end of the U-shaped handle 7 and the right end of the limiting rod 8. An elastic clamping rod 11 is connected to the other end of the U-shaped handle 7. A limiting block 10 for resisting the elastic clamping rod 11 is fixed on the right side of the limiting ring body 1. The limiting rod 8, left arc-shaped elastic rod 13, right arc-shaped elastic rod 12, arc-shaped fixed rod 9, U-shaped handle 7 and elastic clamping rod 11 are integrally formed. The elastic clamping rod 11 is in an arc-shaped bent shape.
[0022] When the limiting ring body 1 is sleeved around the pillow rod for use and the limiting rod 8 is clamped with the limiting groove on the pillow rod, at this time, the bent part at the front end of the elastic clamping rod 11 abuts against the rear end of the limiting block 10, which is beneficial to preventing the limiting ring body 1 from sliding up and down along the pillow rod. Moreover, by pulling the U-shaped handle 7 to drive the deformation of the left arc-shaped elastic rod 13, the limiting rod 8 can be conveniently driven to move out of the limiting ring body 1 through the movable groove 6, and the limiting rod 8 can be conveniently moved out of the limiting groove on the pillow rod. When the U-shaped handle 7 drives the elastic clamping rod 11 to tilt and move away from the limiting block 10, the bent part at the front end of the elastic clamping rod 11 is moved away from the rear end of the limiting block 10, and then the bent part at the rear end of the elastic clamping rod 11 can be conveniently abutted against the front end of the limiting block 10 to prevent the limiting rod 8 from resetting. Therefore, the limiting ring body 1 can be conveniently moved up and down around the pillow rod, and the operation is convenient.
[0023] As Figure 1 、 3 、4 shown, in this embodiment, the limiting rod 8, left arc-shaped elastic rod 13, right arc-shaped elastic rod 12, arc-shaped fixed rod 9, U-shaped handle 7 and elastic clamping rod 11 are integrally formed, and the limiting rod 8, left arc-shaped elastic rod 13, right arc-shaped elastic rod 12, arc-shaped fixed rod 9, U-shaped handle 7 and elastic clamping rod 11 are all made of beryllium copper alloy.
[0024] By integrally forming the limit rod 8, the left arc-shaped elastic rod 13, the right arc-shaped elastic rod 12, the arc-shaped fixing rod 9, the U-shaped handle 7 and the elastic clamping rod 11, and all of them are made of beryllium copper alloy with good elastic performance, they are not easily damaged compared with the prior art, effectively ensuring the service life of the limit rod 8, the left arc-shaped elastic rod 13, the right arc-shaped elastic rod 12, the arc-shaped fixing rod 9, the U-shaped handle 7 and the elastic clamping rod 11. It eliminates the need to use a limit structure composed of multiple scattered parts to achieve the installation and disassembly of the headrest, thereby facilitating the reduction of production costs.
[0025] As Figure 1 , 3 shown, in this embodiment, a left limit plate 2 is fixed to the left side of the limit ring body 1. A left moving port 4 that penetrates through the front and back is opened in the left limit plate 2. The arc-shaped fixing rod 9 passes through the left moving port 4. A right limit plate 3 is fixed to the right side of the limit ring body 1. The right limit plate 3 is located in front of the limit block 10, and a right moving port 5 that penetrates through the front and back is opened in the right limit plate 3. The other end of the U-shaped handle 7 passes through the right moving port 5.
[0026] By limiting the arc-shaped fixing rod 9 through the left moving port 4 in the left limit plate 2 and limiting the other end of the U-shaped handle 7 through the right moving port 5 in the right limit plate 3, the movement of the U-shaped handle 7 driving the elastic clamping rod 11 can be limited, which helps to prevent the accidental ejection of the U-shaped handle 7 and thus reduces the safety hazard during operation.
[0027] As Figure 3 shown, in this embodiment, at least three uniformly distributed guide blocks 14 are connected to the inner wall of the limit ring body 1.
[0028] By slidingly matching the guide blocks 14 with the guide grooves on the pillow rod, when the limit ring body 1 moves up and down along the pillow rod, the guide blocks 14 slide up and down in the guide grooves, avoiding the accidental rotation of the limit ring body 1 outside the pillow rod, thereby ensuring the smoothness of the up and down movement of the limit ring body 1.
