Description

Technical Field

[0001] The utility model relates to the technical field of sealing strips, in particular to an anti-deformation sealing strip for the inner side of an automobile roof rack. Background Art

[0002] An automobile roof rack is a device installed on the roof of an automobile for carrying luggage, goods or equipment. Its primary function is to increase additional luggage storage space for the automobile. When the roof rack carries luggage or equipment, due to the vibration during vehicle driving, relative movement will occur between the roof rack and the vehicle roof. The sealing strip can serve as a buffer layer to reduce the direct friction between the two, thereby reducing wear. The existing anti-deformation sealing strips for the inner side of automobile roof racks are subject to various external forces during use, prone to excessive deformation, affecting their sealing effect and having low stability; and when the automobile roof rack is subjected to external pressure, the sealing strip is prone to excessive deformation due to the inability to buffer the pressure in time, and may even be crushed, with low anti-deformation ability. Content of the Utility Model

[0003] The purpose of the utility model is to solve the defects existing in the prior art, and to propose an anti-deformation sealing strip for the inner side of an automobile roof rack.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: an anti-deformation sealing strip for the inner side of an automobile roof rack, including a first sealing strip body and a second sealing strip body. One end of the first sealing strip body and the second sealing strip body close to each other is fixedly connected with a buffer cavity. A first rubber block is fixedly connected to the bottom end inside the buffer cavity. A groove is formed inside the first rubber block. A convex block is slidably connected inside the groove. A second rubber block is fixedly connected to the top of the convex block. One end of the second rubber block is fixedly connected to the top end inside the buffer cavity.

[0005] As a further description of the above technical scheme:

[0006] One end of the first sealing strip body and the second sealing strip body close to each other is fixedly connected with spring sheets, and multiple groups of spring sheets are provided.

[0007] As a further description of the above technical scheme:

[0008] Hard rubber layers are fixedly connected to both ends of the first sealing strip body and the second sealing strip body far from each other. Card slots are formed on the inner walls of the hard rubber layers.

[0009] As a further description of the above technical scheme:

[0010] Reinforcing ribs are slidably connected inside the card slots. One side of the reinforcing ribs is fixedly connected to the outer sides of the first sealing strip body and the second sealing strip body.

[0011] As a further description of the above technical scheme:

[0012] The sealing strip body 1 and the sealing strip body 2 are in symmetrical directions.

[0013] As a further description of the above technical solution:

[0014] The spring piece is located outside the buffer cavity.

[0015] As a further description of the above technical solution:

[0016] There are multiple groups of the grooves and the bumps.

[0017] The utility model has the following beneficial effects:

[0018] 1. In the utility model, when an external force acts on the car roof rack, the sealing strip body 1 will be squeezed. The sealing strip body 1 squeezes the bump through the buffer cavity and the rubber block 2, so that the bump and the groove can be engaged with each other, which can limit the excessive deformation of the sealing strip body 1 and the sealing strip body 2 in all directions, maintain a relatively stable shape, thereby maintaining a good sealing effect and improving the stability of the anti-deformation sealing strip for the inner side of the car roof rack.

[0019] 2. In the utility model, by arranging a spring piece between the sealing strip body 1 and the sealing strip body 2, it can elastically deform according to the magnitude of the applied pressure, absorb part of the external force energy, thereby reducing the pressure directly borne by the sealing strip and enhancing the anti-deformation ability of the anti-deformation sealing strip for the inner side of the car roof rack.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Referring to Figures 1 - 3 , an embodiment provided by the present invention: a deformation-resistant sealing strip for the inner side of an automobile roof rack, including a first sealing strip body 1 and a second sealing strip body 2. One end of the first sealing strip body 1 and the second sealing strip body 2 close to each other is fixedly connected with a buffer cavity 3. A first rubber block 4 is fixedly connected to the bottom end inside the buffer cavity 3. A groove 5 is formed inside the first rubber block 4. A convex block 6 is slidably connected inside the groove 5. A second rubber block 7 is fixedly connected to the top of the convex block 6. One end of the second rubber block 7 is fixedly connected to the top end inside the buffer cavity 3.

[0027] One end of the first sealing strip body 1 and the second sealing strip body 2 close to each other is fixedly connected with a plurality of spring sheets 8. Both ends of the first sealing strip body 1 and the second sealing strip body 2 far from each other are fixedly connected with hard rubber layers 9, which can effectively protect the first sealing strip body 1 and the second sealing strip body 2 and prevent them from being damaged. A clamping groove 10 is formed in the inner wall of the hard rubber layer 9. A reinforcing rib 11 is slidably connected inside the clamping groove 10, which can effectively resist the bending deformation of the first sealing strip body 1 and the second sealing strip body 2. One side of the reinforcing rib 11 is fixedly connected to the outer sides of the first sealing strip body 1 and the second sealing strip body 2. The first sealing strip body 1 and the second sealing strip body 2 are in a symmetric direction. The spring sheets 8 are located outside the buffer cavity 3. Both the groove 5 and the convex block 6 are provided in plurality.

[0028] Working principle: When an external force acts on the automobile roof rack, it first acts on the first sealing strip body 1. Due to the existence of the buffer cavity 3 at one end of the first sealing strip body 1 and the second sealing strip body 2 close to each other, the external force will be transmitted into the buffer cavity 3. In the buffer cavity 3, the second rubber block 7 will drive the convex block 6 to slide into the groove 5, so that the convex block 6 and the groove 5 are engaged with each other to prevent excessive deformation. During the deformation process, the spring sheets 8 will elastically expand and contract with the deformation of the first sealing strip body 1 and the second sealing strip body 2, absorb part of the external force energy, reduce the pressure, and improve the anti-deformation ability.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
