[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of a simple child safety seat with an adjustable seat angle mechanism. The mechanism is mounted on a base 2, which serves as the mounting and support foundation for the entire adjustment mechanism. It directly adapts to the car seat or related vehicle body structure. The upper surface of the base 2 is provided with a seat body 1, which is the main component for the child to sit on. Its core function is to provide a comfortable and stable seating space for the child. The inner wall of the base 2 has locking holes 5, which, through cooperation with limiting pins 44, provide multiple fixed angle options for the seat body 1. The inner wall of the base 2 is provided with an adjustment component 3, which includes a wrench bracket 3. 1. The wrench bracket 31 is used to drive the chair body 1 to slide along the inner wall of the base 2, directly transmitting the angle adjustment action. The wrench bracket 31 is installed on the lower surface of the chair body 1 and is slidably connected to the inner wall of the base 2. The inner wall of the wrench bracket 31 is provided with a wrench assembly 4, which includes a first sliding block 41. The first sliding block 41 is used to slide on the inner wall of the wrench bracket 31, converting the tension of the elastic strip 45 and the thrust of the spring 33 into the insertion and removal action of the limit pin 44, directly controlling the switching of the locking and unlocking states. The first sliding block 41 is slidably connected to the inner wall of the wrench bracket 31. A spring limiting block 43 is fixedly connected to one end of the wrench bracket 31 near the center. The spring limiting block 43 is used to evenly transmit the pushing or pulling force of the spring 33 to the first sliding block 41, preventing the spring 33 from directly acting on the first sliding block 41 and causing local deformation due to force. A second sliding block 42 is fixedly connected to the lower surface of the first sliding block 41. The second sliding block 42 increases the sliding contact point, improving the stability of the first sliding block 41 during sliding and preventing the first sliding block 41 from wobbling or deviating during horizontal movement. A limiting pin 44 is fixedly connected to the front end of the first sliding block 41 to limit movement. Pin 44 is used to mechanically lock the relative sliding of wrench bracket 31 and base 2, and fix the angle of chair body 1. The front end of the first sliding block 41 is fixedly connected to an elastic strip 45. The elastic strip 45 is used to convert the pulling force of the operator squeezing the handle block 47 into the power to pull the first sliding block 41 and trigger the unlocking action. The front end of the elastic strip 45 is fixedly connected to a connecting block 46. The connecting block 46 is used to buffer the instantaneous impact force of the hand when the operator squeezes the handle block 47, and avoid the pulling force directly acting on the elastic strip 45, causing the elastic strip 45 to break or deform, thereby improving the operating feel and component durability.

[0033] Reference Figure 4 - Figure 5The upper surface of the wrench bracket 31 is provided with a buckle 32, which is used to limit and guide the elastic strip 45. Both the left and right ends of the wrench bracket 31 are provided with second limiting holes 35, which are used to restrict the movement direction of the limiting pin 44, ensuring that the limiting pin 44 can only slide horizontally. This allows it to align with the locking hole 5 of the base 2, preventing misalignment and locking failure. The limiting pin 44 is slidably connected to the inner wall of the second limiting hole 35. The spring limiting block 43 is elastically connected to the inner wall of the wrench bracket 31 via a spring 33. The spring 33 provides the power source for the locking and resetting of the first sliding block 41, and the second sliding block 42 slides... The connecting block 46 is connected to the inner wall of the wrench bracket 31. The front end of the connecting block 46 is fixedly connected to the handle block 47. The handle block 47 is the operating part that the operator can directly contact. The left and right ends of the handle block 47 are fixedly connected to the second limiting block 48. The second limiting block 48 can increase the friction between the hand and the handle block 47 when the operator squeezes the handle block 47, so as to prevent the hand from slipping and causing the operation to fail. The elastic strip 45 is slidably connected to the inner wall of the buckle 32. Multiple sets of buckle holes 5 are provided. Multiple sets of buckle holes 5 are arranged horizontally from front to back on the inner wall of the base 2. The elastic strip 45 is set as a curved structure. The connecting block 46 has elastic deformation capability.

[0034] Working principle: When the chair body angle needs to be adjusted, the operator squeezes the handle block 47. The second limit blocks 48 at both ends of the handle block 47 prevent the hand from slipping or the operation from deviating, ensuring stable force application. The handle block 47 drives the connecting block 46 fixed at the rear end to move. Because the connecting block 46 has elastic deformation capability, it can adapt to the small displacement during the force application process. At the same time, the connecting block 46 pulls the elastic strip 45, causing the bent elastic strip 45 to slide along the inner wall of the buckle 32 and gradually straighten. The rear end of the elastic strip 45 is fixed to the first sliding block 41. Its pulling force drives the first sliding block 41 to move towards the center of the wrench bracket 31. The second sliding block 42 below the sliding block 41 slides synchronously along the inner wall of the wrench bracket 31 to ensure that the first sliding block 41 moves smoothly. When the first sliding block 41 moves, the spring 33 is compressed, which at the same time drives the limit pin 44 to be pulled out from the locking hole 5 of the base 2 until the limit pin 44 is completely retracted into the second limit hole 35 of the wrench bracket 31. At this time, the relative sliding restriction between the wrench bracket 31 and the base 2 is released and it enters the adjustable state. After unlocking, since the wrench bracket 31 is fixedly connected to the chair body 1 and the wrench bracket 31 can slide along the inner wall of the base 2, when the chair body 1 is pushed, the wrench bracket 31 will move back and forth synchronously along the inner wall of the base 2.

[0035] Move the chair body 1 to the position corresponding to the target angle. The multiple sets of horizontally arrayed locking holes 5 on the inner wall of the base 2 provide adjustment positions for different angles. The appropriate locking hole 5 position can be selected according to actual needs. After adjusting to the target angle, release the handle block 47. The tension of the elastic strip 45 disappears, and the compressed spring 33 releases its elastic potential energy, pushing the spring limit block 43 to move away from the spring. This causes the first sliding block 41 and the second sliding block 42 to reset. When the first sliding block 41 resets, its front end limit pin 44 passes through the second limit hole 35 again and inserts into the corresponding locking hole 5 in the base 2, thus re-fixing the wrench bracket 31 to the base 2. At the same time, the elastic strip 45 returns to its bent state under its own elasticity and slides back to the initial position along the inner wall of the buckle 32. The handle block 47 and the connecting block 46 reset with the elastic strip 45, and the entire device returns to the locked state. The angle of the chair body 1 is fixed at the target position, and the adjustment process is completed.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
