Description

Technical Field

[0001] The utility model belongs to the technical field of locking gas springs, and more particularly, to an end pressing mechanism of a locking gas spring. Background Art

[0002] The operation method of the traditional locking gas spring of a baby crib is as follows: First, use one hand to lift the grip of the end pressing mechanism of the locking gas spring upward, touch and press the piston rod at the end of the gas spring to make the gas spring in a telescopic state, and then use the other hand to swing the baby crib frame to complete the displacement of the structure; in this process, the force for lifting the grip may not be in the same direction as the force for swinging the baby crib, making it inconvenient to exert force. Therefore, the defects of the existing operation method of the locking gas spring of a baby crib are: 1. It requires two hands to operate, and the operation process is not comfortable; 2. The operation method of the locking gas spring of a baby crib can only lift the grip in one direction to make the gas spring in a telescopic state. At this time, another force is required to make the gas spring telescopic and drive the baby crib to tilt. This additional force may not be in the same direction as the direction of lifting the grip, forming two reverse forces and affecting the operation comfort.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN 218258318 U discloses a basin-type baby stroller. When in use, the baby basin is arranged on the support frame. By operating the tilting mechanism, the angle of the support frame can be manually adjusted. After the baby basin is adjusted to a suitable position, reset the operating end of the tilting mechanism, and the tilting mechanism locks in the adjusted position, solving the problem that the baby crib cannot tilt. However, its disadvantages are as follows: When the first telescopic member adjusts the tilting position by telescoping, it is easy to operate unstably, causing the baby stroller to vibrate greatly and affecting the comfort of the baby. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an end pressing mechanism of a locking gas spring.

[0005] In order to achieve the above object, the utility model is realized by adopting the following technical solutions:

[0006] An end pressing mechanism of a locking gas spring includes a fixed housing, a grip, a rocker arranged in the fixed housing, and a grip connection welding part arranged on one side of the rocker.

An installation cylinder for connecting with the piston rod of the gas spring is arranged on the side surface of the fixed housing.

[0007] Preferably, a nylon sheet is arranged on the side surface of the rocker, and the nylon sheet is arranged between the grip connection welding part and the rocker. The nylon sheet is connected to the side surface of the rocker by screws.

[0008] Preferably, a threaded hole for threaded connection with the piston rod of the gas spring is provided in the installation cylinder, and when the piston rod of the gas spring is connected to the installation cylinder, the piston rod abuts against the side surface of the rocker.

[0009] Preferably, the handle connecting weldment is hingedly connected to the end of the fixed housing through the first nut and the first bolt.

[0010] Preferably, the end of the rocker is hingedly connected to the fixed housing through the second bolt and the second nut.

[0011] Preferably, the handle connecting weldment is of a U-shaped structure.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the combined design of the fixed housing, rocker, handle connecting weldment and handle, effective pressing control of the piston rod of the gas spring is achieved. The installation cylinder is directly integrated on the side of the fixed housing, simplifying the assembly process of the gas spring and improving the compactness and stability of the overall structure;

[0014] 2. A nylon sheet is added on the side of the rocker, located between the handle connecting weldment and the rocker, to make the force transmission effect better, effectively reducing friction and wear during movement, improving the service life of the mechanism, reducing noise during operation, and enhancing the use experience;

[0015] 3. By connecting the nylon sheet to the side of the rocker with screws, it not only facilitates the installation and replacement of the nylon sheet, but also ensures the stability of the nylon sheet under the stressed state, further optimizing the wear resistance and working reliability of the mechanism;

[0016] 4. A threaded hole for threaded connection with the piston rod of the gas spring is designed in the installation cylinder, achieving precise docking of the piston rod and the pressing mechanism, enhancing the fastening and sealing of the connection, ensuring the stability and response speed of the gas spring during operation, and improving the overall working efficiency of the system;

[0017] 5. The handle connecting weldment is hingedly connected to the end of the fixed housing by the first nut and the first bolt, which not only facilitates adjustment and maintenance, but also enhances the flexibility and load-bearing capacity of the structure, making the operation of the handle smoother and more durable;

[0018] 6. The design that the end of the rocker is hingedly connected to the fixed housing through the second bolt and the second nut improves the strength and stability of the hinged part, ensuring the smoothness and accuracy of the rocker movement under long-term use, and avoiding functional failure caused by loosening;

[0019] 7. The handle connecting weldment adopts a U-shaped structure, enhancing the strength of the fixed connection with the bottom of the baby crib;

[0020] In summary, the utility model utilizes a cam-rocker mechanism to complete the function of a two-way drive locking gas spring. The handle connecting weldment can be regarded as a cam. When the handle is swung up and down, the handle connecting weldment rotates up and down, which can push the rocker to swing, and then touch the piston rod at the end of the locking gas spring, making the gas spring become a telescopic state. Thus, the tilting operation of the baby crib can be realized. Since swinging the handle in both directions can make the gas spring become a telescopic state, it is ensured that the swinging direction of the handle is always consistent with the tilting direction of the baby crib, so that all the forces received during the tilting of the baby crib do positive work, making the tilting operation process of the baby crib more comfortable.
