Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing technology and relates to a manual locking mechanism for a radiator water chamber. Background Technology

[0002] As the core component of a radiator, the radiator water chamber mainly consists of an inlet chamber, an outlet chamber, and a sealing structure connected to the radiator core. Its functions include coolant distribution, pressure bearing, and structural sealing. Traditional water chambers are mostly injection molded using PA66+GF30, with internal reinforcing ribs (such as external wall reinforcing ribs and horizontal tie ribs) to improve structural strength. Some water chambers adopt a split design to adapt to the piping layout.

[0003] In the assembly process, the quality of the engagement between the main plate and the snap-fit ​​teeth directly affects the water chamber's sealing performance. The main plate is typically a thin metal sheet with multiple snap-fit ​​teeth along its edges, requiring precise engagement with the plastic water chamber shell to form a seal. Traditional engagement processes often rely on manual hammering or pressing with simple tools, which presents the following problems:

[0004] 1. Inaccurate control of the fastening force can easily lead to excessive deformation of the fastening teeth or loose fastening.

[0005] 2. Low operational efficiency, making it difficult to achieve consistency in mass production;

[0006] 3. Manual operation can easily cause damage to the surface of the main film. Utility Model Content

[0007] In view of this, the purpose of this utility model is to solve the above problems and provide a manual locking mechanism for radiator water chambers.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A manual locking mechanism for a radiator water chamber includes a guide rail. A main plate is placed on one side of the guide rail via a positioning fixture, and a slider is provided on the other side for sliding engagement with the main plate. The slider has a first connecting block and a second connecting block. One end of the first connecting block is rotatably connected to the slider via a shaft, and the second connecting block is rotatably connected to the other end of the first connecting block via a shaft. A handle and a locking block are fixedly provided on the second connecting block, with one end of the locking block extending from the second connecting block to one side of the main plate. A limiting block is fixedly provided on the side of the first connecting block closest to the main plate to limit the rotation angle of the first connecting block.

[0010] A spring is provided between the first connecting block and the second connecting block. The spring is always in a compressed state, and the initial elastic force of the spring is greater than the yield force of the teeth to be pushed down on the main plate. When fastening, the handle drives the first connecting block, the second connecting block, and the fastening block to rotate synchronously around the slider. During the rotation, the fastening block pushes down the teeth on the main plate. When the first connecting block reaches the rotation limit, the handle drives the connecting B to compress the spring, so that the second connecting block drives the fastening block to rotate around the first connecting block, thereby pressing down the teeth on the main plate.

[0011] Furthermore, the height of the rotational connection point between the second connecting block and the first connecting block is greater than the height of the rotational connection point between connection A and the slider.

[0012] Furthermore, when the main sheet is pressed down, the first connecting block rotates at a 3° angle relative to the slider, and the second connecting block rotates at a 1° angle relative to the first connecting block.

[0013] Furthermore, the guide rail is arranged parallel to the main piece, and the fastening block is perpendicular to the main piece.

[0014] Furthermore, the first connecting block is provided with a mounting hole, and the spring is disposed in the mounting hole.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1) Staged operation to ensure fastening accuracy: This utility model ensures the accuracy and reliability of the fastening process by dividing the fastening process into two stages: pushing down the main teeth and pressing down the main teeth, thus avoiding fastening failure due to improper operation.

[0017] 2) Optimize mechanical design to improve operational stability: In the first stage, the fastening block pushes down the main teeth, reducing the resistance of the main teeth; in the second stage, the second connecting block drives the fastening block to press down the main teeth, ensuring the stability of the fastening process and reducing the uncertainty in the operation process.

[0018] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention.

[0028] Please see Figures 1-4This is a manual locking mechanism for a radiator water chamber, comprising a guide rail 1, on one side of which a main plate 2 is placed via a positioning fixture, and on the other side of which a slider 4 is slidably engaged with the main plate 2. The slider 4 is provided with a first connecting block 6 and a second connecting block 8. One end of the first connecting block 6 is rotatably connected to the slider 4 via a shaft, and the second connecting block 8 is rotatably connected to the other end of the first connecting block 6 via a shaft. A handle 5 and a locking block 3 are fixedly mounted on the second connecting block 8, with one end of the locking block 3 extending from the second connecting block 8 to one side of the main plate 2. The guide rail 1 is arranged parallel to the main plate 2, and the locking block 3 is perpendicular to the main plate 2. A limit block is fixedly mounted on the side of the first connecting block 6 closest to the main plate 2 to limit the rotation angle of the first connecting block 6.

[0029] A spring 7 is provided between the first connecting block 6 and the second connecting block 8. The spring 7 is always in a compressed state, and the initial elastic force of the spring 7 is greater than the yield force of the teeth to be pushed down on the main plate 2. When fastening, the handle 5 drives the first connecting block 6, the second connecting block 8, and the fastening block 3 to rotate synchronously around the slider 4. During the rotation, the fastening block 3 pushes down the teeth on the main plate 2. When the first connecting block 6 reaches the rotation limit, the handle 5 drives the connecting block B to compress the spring 7, so that the second connecting block 8 drives the fastening block 3 to rotate around the first connecting block 6, thereby pressing down the teeth on the main plate 2.

[0030] The height of the rotating connection point between the second connecting block 8 and the first connecting block 6 is greater than the height of the rotating connection point between connection A and slider 4. When the main plate 2 is pressed down, the rotation angle of the first connecting block 6 relative to the slider 4 is 3°, and the rotation angle of the second connecting block 8 relative to the first connecting block 6 is 1°. A mounting hole is provided inside the first connecting block 6, and the spring 7 is located in the mounting hole.

[0031] After all the parts to be processed are installed, they are pushed into the guide rail 1. The main piece 2 is hung on the guide rail 1 by the tooling. The fastening block 3 and the handle 5 are fastened to the second connecting block 8 by screws. The spring 7 is between the first connecting block 6 and the second connecting block 8. Because spring 7 is always under compression, its force is greater than the yield force of the teeth that push down the main plate 2. The first connecting block 6 and the second connecting block 8 are connected by a shaft (hinged). The fastening process is divided into two stages. In the first stage, when the handle 5 is pulled up, the second connecting block 8 is driven, and spring 7 pushes against the first connecting block 6. The first connecting block 6 and the slider 4 are connected by a shaft (hinged). At this time, the second connecting block 8, the fastening block 3, spring 7, and the first connecting block 6 rotate simultaneously along the axis center on the slider 4. During the rotation of the fastening block 3, the teeth on the main plate 2 are pushed down by the fastening block 3. During this process, the smaller the horizontal center position distance A of the hinge point, the closer the movement trajectory of the fastening block 3 is to the horizontal. In the second stage, the handle 5 is pulled up again. When the first connecting block 6 reaches the limit point and stops moving, spring 7 begins to compress. At this time, the second connecting block 8 and the fastening block 3 rotate along the axis center on the second connecting block 8 to achieve the fastening (pressing) of the main plate 2. During this process, the smaller the vertical center position distance B of the hinge point, the closer the movement trajectory of the fastening block 3 is to the vertical downward.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
