Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of lower shell cover, more specifically to the suction base. BACKGROUND

[0002] The lower shell cover can be adsorbed on a smooth plane, and the object is conveniently installed on the smooth plane. The products commonly adsorbed on the smooth plane in life include a lower shell cover hook, a lower shell cover type mobile phone support and the like. The lower shell cover is generally in a bowl shape.

[0003] The working principle of the lower shell cover is that a user places the lower shell cover on a smooth plane, presses the center of the lower shell cover, and squeezes out the air between the lower shell cover and the smooth plane. The lower shell cover is pressed on the smooth plane by atmospheric pressure.

[0004] The common reasons for failure of the lower shell cover are as follows:

[0005] 1. Aging of the lower shell cover: The material of the lower shell cover will age and become hard, losing elasticity, and affecting the adsorption effect due to long-term use or exposure to high temperature, ultraviolet light and the like.

[0006] 2. Foreign matter in the lower shell cover: Dust or sundries entering the inside of the lower shell cover will damage the sealing property, resulting in failure.

[0007] At the same time, the lower shell cover type mobile phone support of the prior art is prone to falling off due to vibration and the like, and the bowl-shaped lower shell cover is prone to deformation failure due to long-term close contact with the plane. SUMMARY

[0008] Therefore, the utility model provides a suction base suitable for being installed on a desktop or a vehicle center console and stable in assembly.

[0009] In order to achieve the above purpose, the utility model adopts the following technical scheme: a suction base comprising:

[0010] an upper shell cover;

[0011] a lower shell cover installed at the bottom of the upper shell cover;

[0012] a support located in the upper shell cover and connected with the lower shell cover;

[0013] a handle movable or rotatable relative to the upper shell cover, the handle being connected with the support through a shaft body;

[0014] When the handle is moved or rotated relative to the upper shell cover, the shaft body drives the support to move away from or close to the adsorbed surface of the lower shell cover, so that the volume of the cavity formed between the lower shell cover and the adsorbed surface changes.

[0015] As one preferred scheme of the utility model, the lower shell cover comprises: an adsorption part and a deformable part, the adsorption part is arranged at the outer edge of the deformable part; the bottom edge of the upper shell cover is assembled with the upper surface of the adsorption part.

[0016] As one preferred scheme of the utility model, the support is connected with the deformable part partially.

[0017] As one preferred scheme of the utility model, the support is partially covered in the deformable part.

[0018] As one preferred scheme of the utility model, the lower shell cover further comprises: a force applying part, the force applying part is connected with the outer edge of the adsorption part and protrudes radially;

[0019] The adsorption part, the deformable part and the force applying part are integrally injection molded.

[0020] As one preferred scheme of the utility model, the support comprises: a bottom plate and a connecting lug; the shaft body passes through the connecting lug;

[0021] A spring is arranged between the bottom plate and the connecting lug.

[0022] As one preferred scheme of the utility model, the upper shell cover is provided with a waist-shaped hole; the handle is provided with a boss, one end of the boss is provided with a shaft hole;

[0023] The shaft body is inserted into the shaft hole after passing through the waist-shaped hole.

[0024] As one preferred scheme of the utility model, the upper shell cover is provided with a contact surface below the waist-shaped hole;

[0025] The outer peripheral wall of the boss is in contact with the contact surface;

[0026] When the handle rotates, the shaft body is pushed to move along the waist-shaped hole with the change of the contact position of the contact surface and the boss.

[0027] As one preferred scheme of the utility model, the handle can be rotated to a first position and a second position;

[0028] When the handle is rotated to the second position, the handle is located at the circumferential side of the upper shell cover.

[0029] As one preferred scheme of the utility model, the bottom of the upper shell cover is provided with a mounting position.

[0030] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects: The present invention is simple to use. After placing the suction base on a flat surface, turning the handle can drive the bracket to rise, which increases the volume of the cavity formed between the lower shell cover and the suction surface, forming a negative pressure. The air pressure is used to press the lower shell cover tightly onto the flat surface, and the installation is stable, and the suction base is not easy to fall off. Furthermore, when the suction base is applied to the field of mobile phone holders, it enables the mobile phone holder to be stably installed on the center console.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0042] For the suction base, please refer to [link / reference]. Figures 1-6 As shown, it includes: an upper cover 100, a lower cover 200, a bracket 300, and a handle 400.

[0043] The lower cover 200 is installed at the bottom of the upper cover 100, and the lower cover 200 and the upper cover 100 form an installation space. The upper cover 100 can be made of metal or hard plastic, while the lower cover 200 can be made of soft rubber. The lower cover 200 has the characteristics of being able to fit tightly to a smooth surface and being deformable.

[0044] The handle 400 is installed on the upper cover 100. The handle 400 can move or rotate relative to the upper cover 100. The handle 400 is connected to the bracket 300 through the shaft 500.

[0045] When the handle 400 moves or rotates relative to the upper cover 100, it drives the bracket 300 to move away from or closer to the adsorption surface of the lower cover 200 via the shaft 500, causing a change in the volume of the cavity formed between the lower cover 200 and the adsorption surface.

[0046] Specifically, when the handle 400 moves or rotates relative to the upper cover 100, the shaft 500 moves upward, pulling the middle of the lower cover 200 to deform, which in turn increases the cavity area formed between the lower cover 200 and the adsorption surface, thereby reducing the negative pressure in the cavity. The edge of the lower cover 200 is pressed against the adsorption surface by external air pressure, making the suction base installation stable.

[0047] Furthermore, the lower shell cover 200 includes an adsorption portion 210 and a deformable portion 220, with the adsorption portion 210 disposed on the outer edge of the deformable portion 220; the bottom edge of the upper shell cover 100 is fitted to the upper surface of the adsorption portion 210.

[0048] Specifically, the deformable part 220 of the lower cover 200 is circular, the adsorption part 210 is distributed on the outer edge of the deformable part 220, and the lower surface of the adsorption part 210 is a smooth surface with a certain degree of inclination.

[0049] like Figure 6 As shown, the lower surface of the adsorption section 210 gradually slopes upward from the outside to the inside;

[0050] Optionally, the lower surface of the adsorption part 210 may also be a horizontally arranged smooth surface.

[0051] After the suction base is placed on the adsorption surface, the lower surface of the adsorption part 210 is attached to the adsorption surface, thus isolating the cavity formed between the deformable part 220 and the adsorption surface from the outside air.

[0052] Furthermore, the bracket 300 is partially connected to the deformable part 220;

[0053] Specifically, the bracket 300 is connected at the middle part of the deformable part 220, and the deformation of the deformable part 220 is better controlled;

[0054] Further, since the deformable part 220 is made of soft rubber material, the bracket 300 is partially covered in the deformable part 220 during manufacturing. This manufacturing method is simple and effectively reduces the assembly steps.

[0055] Optionally, the bracket 300 and the deformable part 220 can also be connected through other connection structures, such as being mounted through the embedded structure of the concave-convex matching between the bracket 300 and the deformable part 220.

[0056] The bracket 300 can be made of metal material or hard plastic material.

[0057] In an embodiment, the lower shell cover 200 further comprises a force applying part 230 connected to the outer edge of the suction part 210 and radially protruding; the suction part 210, the deformable part 220 and the force applying part 230 are integrally injection molded.

[0058] The lower shell cover 200 is simple and convenient to manufacture as a whole.

[0059] After the handle 400 of the suction base is restored to the position as shown in Figure 1 The bracket 300 moves downward, the deformable part 220 resets, and the cavity area decreases. Then the user applies force to pull the force applying part 230 from one side, which makes it easier to lift the suction base.

[0060] Further, the bracket 300 comprises a bottom plate 310 and a connecting lug 320; the shaft body 500 passes through the connecting lug 320; and a spring 330 is arranged between the bottom plate 310 and the connecting lug 320.

[0061] The spring 330 prevents the suction base from being released after the handle 400 is moved, and the suction base is more stable in suction.

[0062] Further, the upper shell cover 100 is provided with a waist-shaped hole 110; the handle 400 is provided with a boss 410, one end of the boss 410 is provided with a shaft hole 411;

[0063] The shaft body 500 passes through the waist-shaped hole 110 and is inserted into the shaft hole 411;

[0064] As shown in Figure 3 The waist-shaped hole 110 is vertically arranged, the handle 400 is generally in the shape of U, and the handle 400 is rotatably connected to the upper shell cover 100 through the shaft body 500;

[0065] As shown in Figure 1As shown, before sucking the suction base to the adsorption surface, the handle 400 is in the first position, which is roughly rotated away from the side of the upper shell cover 100;

[0066] After rotating the handle 400 by force, and rotating to Figure 2 the second position shown, the handle 400 is rotated to the side of the upper shell cover 100, and the suction base can suck the adsorption surface.

[0067] Further, the bottom of the upper shell cover 100 is provided with a mounting position, so that the handle 400 can be stored in the side of the upper shell cover 100, and the overall structure is more regular.

[0068] Further, the upper shell cover 100 is provided with a contact surface 120 below the waist-shaped hole 110; the outer peripheral wall of the boss 410 is in contact with the contact surface 120; when the handle 400 rotates, the shaft body 500 moves along the waist-shaped hole 110 with the change of the contact position of the contact surface 120 and the boss 410.

[0069] The specific use principle of the utility model will be further described below:

[0070] Please refer to Figures 1-3 the drawing, Figure 1 the handle 400 is in the first position, the suction base is placed on the smooth plane, the adsorption part 210 is in contact with the smooth plane, and at this time the shaft body 500 is located at the lower end of the waist-shaped hole 110;

[0071] Rotate the handle 400 by force, and rotate the handle 400 to Figure 2 the second position shown, and in the rotating process, under the action of the variable diameter of the boss 410 and the interaction of the boss 410 and the contact surface 120, the rotary motion of the handle 400 is converted into the linear motion of the shaft body 500, and the shaft body 500 moves upward and can move to the upper end of the waist-shaped hole 110;

[0072] In the process of moving the shaft body 500 upward, the bracket 300 is moved upward, and the deformable part 220 is deformed upward, so that the space volume between the deformable part 220 and the smooth plane is increased, and then the negative pressure is formed, and the lower shell cover 200 is pressed tightly on the smooth plane by atmospheric pressure;

[0073] When disassembling, rotate the handle 400 in the opposite direction, and reset the handle 400 to Figure 1 the first position shown, at this time the shaft body 500 and the bracket 300 move downward, so that the space volume between the deformable part 220 and the smooth plane is reduced, so that the internal and external pressures are parallel or tend to be parallel;

[0074] Finally, the lower shell cover 200 is pulled by the force part 230, and the entire lower shell cover 200 is lifted, and the suction base is disassembled.

[0075] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application.
