Description

Technical Field

[0001] This utility model relates to the field of headrest locking block installation equipment, specifically a headrest locking block automatic insertion device into the headrest rod. Background Technology

[0002] Car headrests are mainly used to support the head of passengers, and the headrests also play a cushioning role. In order to facilitate the installation and adjustment of car headrests, headrest guide sleeves are usually used to lock the car headrests. Existing headrest guide sleeves require a locking button to unlock the headrest, and the locking button is located directly below the headrest. The headrest locking block needs to be installed during the initial headrest installation.

[0003] According to the patent document CN221023386U, a headrest locking mechanism includes a guide sleeve assembly, an installation assembly, and an unlocking assembly. The guide sleeve assembly includes a first guide sleeve and a second guide sleeve fixed to a horizontal tube on the backrest. Both the first and second guide sleeves include a conduit for inserting a headrest rod. The upper end of the conduit is provided with a cap, and the cap is provided with a first through hole communicating with the conduit. In use, by adding the installation assembly and the unlocking assembly, the unlocking button is positioned away from directly below the headrest, which avoids the headrest obstructing the unlocking button and causing inconvenience in locking operation. Furthermore, by adding the unlocking assembly, the lateral thrust of unlocking the existing headrest guide sleeve is transformed into a downward pressing force, making the locking operation more convenient. Regarding the above technical solution, although it facilitates the locking operation, it is inconvenient to install the locking block by clamping and fixing the headrest rod in the early stage. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an automatic headrest locking block insertion device for the headrest rod, thereby solving the problems mentioned in the background art. This utility model has a novel structure. In use, the headrest rod is installed inside the mounting groove and the fixing groove. The left and right limits of the headrest rod are achieved by the movement of the limiting seat, and the front and rear limits of the headrest rod are achieved by the horizontal movement of the movable seat, ensuring the fixation of the headrest rod and facilitating the subsequent assembly of the locking rod and the headrest cover.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic headrest locking block insertion headrest rod device, comprising a base, a fixing column fixed at the bottom of the base, a fixing tube movably installed at one end of the fixing column, a reinforcing rod welded between the fixing tubes, a horizontal plate welded between the reinforcing rods, displacement mechanisms fixed at both ends of the base, a fixing block fixed at the top of the base, a pushing mechanism fixedly installed on the fixing block, and a movable seat fixed at one end of the pushing mechanism.

[0006] Furthermore, the base has a groove, and a slider is movably installed inside the groove, with one end of the slider fixed to the bottom of the movable seat.

[0007] Furthermore, the base has a slot, a support block is fixed inside the slot, and a threaded post is fixed at the bottom of the support block.

[0008] Furthermore, a threaded tube is rotatably mounted on the threaded column, and the threaded tube is mounted on the horizontal plate via a bearing seat.

[0009] Furthermore, a movable column is installed on the displacement mechanism, and a limit seat is fixed at one end of the movable column.

[0010] Furthermore, a limiting block is fixed on the limiting seat, and a limiting groove is opened on the base, with the limiting block movably installed inside the limiting groove.

[0011] Furthermore, the limiting seat has a fixing groove, which cooperates with the groove.

[0012] Furthermore, the movable seat has a mounting groove, and a headrest rod is movably mounted inside the mounting groove.

[0013] The beneficial effects of this utility model are:

[0014] 1. In use, the headrest rod is installed inside the mounting groove and the fixing groove. The left and right limits of the headrest rod are completed by the movement of the limiting seat, and the front and rear limits of the headrest rod are completed by the horizontal movement of the movable seat, so as to ensure the fixation of the headrest rod and facilitate the later assembly of the locking rod and the headrest cover.

[0015] 2. In this utility model, the height between the base and the ground is adjusted according to the length of the headrest rod. The headrest rod slides inside the fixed groove and contacts the ground, so that the mounting seat at the headrest rod contacts the movable seat for limiting. The threaded tube rotates on the threaded column to push the fixed tube up and down to adjust the overall height of the base. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: an automatic headrest locking block insertion device for headrest rods, including a base 1, a fixing column 3 fixed at the bottom of the base 1, a fixing tube 4 movably installed at one end of the fixing column 3, a reinforcing rod 5 welded between the fixing tubes 4, a cross plate 6 welded between the reinforcing rods 5, a displacement mechanism 2 fixed at both ends of the base 1, a fixing block 7 fixed at the top of the base 1, a pushing mechanism 8 fixedly installed on the fixing block 7, a movable seat 9 fixed at one end of the pushing mechanism 8, a sliding groove 12 opened on the base 1, a slider 15 movably installed inside the sliding groove 12, one end of the slider 15 fixed to the bottom of the movable seat 9, the pushing mechanism 8 and the displacement mechanism 2 are both linear reciprocating electric push rods, the displacement mechanism 2 drives the limiting seat 16 to move through the movable column 19, and the movement of the limiting seat 16 completes the limiting and fixing of the headrest rod 11 through the fixing groove 18.

[0025] In this embodiment, the base 1 has a slot 13, and a support block 14 is fixed inside the slot 13. A threaded column 22 is fixed at the bottom of the support block 14. A threaded tube 20 is rotatably mounted on the threaded column 22. The threaded tube 20 is mounted on the horizontal plate 6 through a bearing seat 21. A movable column 19 is mounted on the displacement mechanism 2. A limit seat 16 is fixed at one end of the movable column 19. The position of the threaded tube 20 on the threaded column 22 is changed by rotating the bearing seat 21. The displacement of the threaded tube 20 pushes the fixed tube 4 to move on the fixed column 3, thereby adjusting the height of the base 1 from the ground.

[0026] In this embodiment, a limiting block 17 is fixed on the limiting seat 16, a limiting groove is opened on the base 1, the limiting block 17 is movably installed inside the limiting groove, a fixing groove 18 is opened on the limiting seat 16, the fixing groove 18 cooperates with the slot 13, an installation groove 10 is opened on the movable seat 9, a headrest rod 11 is movably installed inside the installation groove 10, and the limiting block 17 slides inside the limiting groove to provide secondary upper and lower limiting force for the limiting seat 16 as a whole, ensuring the horizontal movement of the limiting seat 16 in the future.

[0027] Working principle: In use, the headrest rod 11 is installed inside the fixed groove 18 through the mounting groove 10. The headrest rod 11 moves downward so that one end contacts the ground. When the headrest seat installed on the headrest rod 11 is not in contact with the top of the movable seat 9, the threaded tube 20 moves on the threaded column 22 by rotating. The movement of the threaded tube 20 pushes the fixed tube 4 on the fixed column 3 through the horizontal plate 6 and the reinforcing rod 5. The movement of the fixed tube 4 pushes the base 1 upward, so that one end of the headrest rod 11 contacts the ground and the headrest seat contacts the top of the movable seat 9. The movable seat 9 and the headrest seat cooperate to achieve the headrest... The upper and lower limits of the headrest rod 11 are set by activating the displacement mechanism 2 after the headrest rod 11 is installed, which drives the limit seat 16 to move to both ends. The movement of the limit seat 16 causes the headrest rod 11 to be limited to the left and right under the tension of the fixed groove 18. After the headrest rod 11 is limited to the left and right, the push mechanism 8 is activated to push the movable seat 9 to move. The movement of the movable seat 9 completes the front and rear compression limit of the headrest rod 11 through the inner wall of the mounting groove 10. After the headrest rod 11 is limited and fixed, the headrest locking block is installed at the headrest rod 11 and the headrest seat. Then the headrest cover is installed on the headrest seat for use, which facilitates the overall assembly of the headrest later.
