[0035] In order to make the technical problems, technical schemes and beneficial effects to be solved in the present application more clearly, the present application will be further described in detail in combination with the drawings and embodiments.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0041] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0042] In order to solve the technical problem in the prior art that when the connection between the transmission rod 2 and the rubber sleeve 31 is not stable, it is easy to cause the adsorption plate to fail to form sufficient negative pressure due to the inability to properly extract air, thereby reducing the adsorption force of the adsorption plate on the bonding surface, this utility model embodiment provides an air exhaust structure.

[0043] The following describes in detail the specific structure of an air exhaust and suction structure provided by an embodiment of this utility model, according to the appendix. Figures 1-4 As shown, the specific structure of the air exhaust and suction structure includes a driver 1, a transmission rod 2, an exhaust and suction assembly 3, and a locking assembly 4.

[0044] according to Figure 1 As shown, one end of the transmission rod 2 is connected to the driver 1 for driving.

[0045] Specifically, the driver 1 serves as a power source, which can rotate to generate power through a power output shaft. Since the transmission rod 2 is connected to the power output shaft, the power generated by the power output shaft is transmitted to the exhaust and suction assembly 3 through the transmission rod 2, so that the exhaust and suction assembly 3 operates to achieve the extraction of air and form a negative pressure between the adsorption disc and the adhering surface.

[0046] According to Figure 1 As shown in FIGS. 1, 2 and 3, the exhaust and suction assembly 3 comprises a rubber sleeve 31 and an exhaust and suction member 32, and the exhaust and suction member 32 has a gas cavity 321 formed therein. The rubber sleeve 31 is arranged to be sleeved on the other end of the connecting rod and arranged to be embedded in the gas cavity 321 of the exhaust and suction member 32.

[0047] Specifically, when the driver 1 is used to drive the transmission rod 2 to move, the rubber sleeve 31 is pulled to move and expand when the transmission rod 2 moves. At this time, the volume of the gas cavity 321 in the exhaust and suction member 32 gradually increases, the internal air pressure decreases to form a negative pressure, and the external air is then sucked into the gas cavity 321. Conversely, when the driver 1 is used to drive the transmission rod 2 to reset, the direction of the force of the transmission rod 2 on the rubber sleeve 31 changes, and the rubber sleeve 31 gradually returns to its original shape. In this process, the rubber sleeve 31 shrinks, the volume of the gas cavity 321 decreases, and the pressure of the gas in the gas cavity 321 increases according to Boyle's law. When the volume of the gas cavity 321 decreases, the pressure of the gas in the gas cavity 321 increases, and the gas is then discharged to the outside through the exhaust passage under the action of the pressure difference. Thus, as the rubber sleeve 31 gradually returns to its original shape under the driving of the transmission rod 2, the gas in the gas cavity 321 is gradually discharged, and the exhaust process is completed.

[0048] According to Figure 3 and Figure 4 As shown in FIGS. 1, 2 and 3, the exhaust and suction assembly 3 comprises a rubber sleeve 31 and an exhaust and suction member 32, and the exhaust and suction member 32 has a gas cavity 321 formed therein. The rubber sleeve 31 is arranged to be sleeved on the other end of the connecting rod and arranged to be embedded in the gas cavity 321 of the exhaust and suction member 32.

[0049] Specifically, by setting the locking cover 41 on the rubber sleeve 31, at this time the locking hole 411 of the locking cover 41 is in correspondence with the fixed hole 21 on the transmission rod 2, and then the locking member 42 is simultaneously threaded into the locking hole 411 and the fixed hole 21, so that the rubber sleeve 31 and the transmission rod 2 are more firmly connected. In this way, when the driver 1 drives the transmission rod 2 to move, the rubber sleeve 31 can stably follow the movement of the transmission rod 2 and deform, ensuring that the volume of the air cavity 321 effectively changes, thereby realizing stable air suction and exhaust functions and preventing the rubber sleeve 31 from being easily displaced or detached from the transmission rod 2.

[0050] In addition, since the locking member 42 is detachably threaded into the locking hole 411 and the fixed hole 21, the rubber sleeve 31 and the transmission rod 2 are more convenient to assemble and disassemble. For example, during assembly, the rubber sleeve 31 can be easily assembled with one end of the transmission rod 2 through the locking cover 41 and the locking member 42, thereby improving assembly efficiency. During use, if the rubber sleeve 31 or the transmission rod 2 needs to be replaced or repaired due to damage or aging, the locking member 42 can be quickly disassembled, and then the rubber sleeve 31 can be separated from one end of the transmission rod 2.

[0051] In some specific embodiments, the locking member 42 is a bolt, and the fixed hole 21 is a screw hole.

[0052] Specifically, when the bolt is threaded through the locking hole 411 of the locking cover 41, it is aligned with the screw hole on the transmission rod 2, and then the bolt is inserted into the screw hole and rotated. Since the external threads of the bolt and the internal threads of the screw hole match each other, when the bolt is rotated, the external threads of the bolt and the internal threads of the screw hole will generate a mutual force. With the continuous rotation of the bolt, the bolt advances along the helical line direction of the threads, while generating an axial tension, which generates a friction force between the mating surfaces of the bolt and the screw hole. The friction force prevents the bolt from loosening, thereby achieving the fastening connection of the bolt and the screw hole. Since the locking cover 41 is set on the rubber sleeve 31 at this time, when the bolt is threaded through the locking hole 411 and the screw hole in turn and tightened, the tension of the bolt is transmitted to the rubber sleeve 31 through the locking cover 41, so as to fasten the locking cover 41 on the transmission rod 2, and thereby firmly fix the rubber sleeve 31 on one end of the transmission rod 2.

[0053] In addition, the detachability of the bolt provides convenience for the replacement and maintenance of the rubber sleeve 31. For example, by unscrewing the bolt, the locking cover 41 and the rubber sleeve 31 can be easily removed.

[0054] According to Figure 4 As shown in FIG. 8, in a further embodiment, the hole wall of the locking hole 411 is formed with a first inclined surface 412, and one end of the bolt is provided with a screw cap formed with a second inclined surface 421 for abutting against the first inclined surface 412.

[0055] Specifically, when the bolt is inserted into the locking hole 411 and moves to the position where the first inclined surface 412 and the second inclined surface 421 are in contact, under the guidance of the second inclined surface 421, even if there is a certain angular deviation when the bolt is initially inserted, it can be gradually guided to the correct position under the action of the second inclined surface 421, so that the bolt can be accurately aligned with the screw hole on the transmission rod 2, facilitating subsequent tightening operation, thereby improving the accuracy and convenience of installation, and by the first inclined surface 412 and the second inclined surface 421 being in close contact, compared with planar contact, a larger contact area can be provided in a smaller space, thereby helping to disperse the pressure generated when the bolt is tightened, reducing local stress concentration, so that the pressure on the rubber sleeve 31 when it is fixed is more uniform, to improve the stability and reliability after the rubber sleeve 31 is fixed. In addition, when the bolt is tightened, the second inclined surface 421 of the screw cap generates a component force perpendicular to the inclined surface under the action of the first inclined surface 412, which can further increase the friction between the bolt and the screw hole, thereby enhancing the fastening effect of the bolt connection, making it difficult for the rubber sleeve 31 to loosen during long-term use.

[0056] According to Figure 3 and Figure 4 It is shown that in some specific embodiments, the transmission rod 2 is provided with a protruding portion 22 at one end close to the rubber sleeve 31, and the rubber sleeve 31 is sleeved on the outer side wall of the protruding portion 22.

[0057] Specifically, the protruding portion 22 is used to define the installation position of the rubber sleeve 31, when the rubber sleeve 31 is sleeved on the outer side wall of the protruding portion 22, so that the rubber sleeve 31 can be accurately positioned on the transmission rod 2, ensuring that the relative position between the rubber sleeve 31 and the transmission rod 2 is fixed and accurate, avoiding the rubber sleeve 31 from shifting or shaking during installation, thereby ensuring the assembly accuracy of the two, and the protruding portion 22 is used to increase the contact area between the transmission rod 2 and the rubber sleeve 31, that is, when the rubber sleeve 31 is sleeved on the outside of the protruding portion 22, the friction and bonding force between the two are stronger, making it difficult for the rubber sleeve 31 to fall off the transmission rod 2, thereby improving the stability of the connection between the rubber sleeve 31 and the transmission rod 2.

[0058] According to Figure 4 It is shown that in some optional embodiments, the locking cover 41 is recessed with an annular groove 413, and the rubber sleeve 31 is protruded with an annular protrusion 311 for being inserted into the annular groove 413, and the annular protrusion 311 is inserted into the annular groove 413; or, the rubber sleeve 31 is recessed with an annular groove 413, and the locking cover 41 is protruded with an annular protrusion 311 for being inserted into the annular groove 413.

[0059] Specifically, since the annular protrusion 311 and the annular groove 413 are matched in shape and size, when the annular protrusion 311 on the rubber sleeve 31 is inserted into the corresponding annular groove 413 of the locking cover 41, accurate positioning for the installation of the rubber sleeve 31 is provided, ensuring that the rubber sleeve 31 can be accurately assembled at the specified position of the locking cover 41. This arrangement can prevent errors during installation and avoid the situation that the rubber sleeve 31 is not installed in place. In addition, when the annular protrusion 311 is inserted into the annular groove 413, a tight fit is formed between the two, which increases the contact area and connection points between the rubber sleeve 31 and the locking cover 41, making the connection between the rubber sleeve 31 and the locking cover 41 more stable.

[0060] It should be noted that the two setting modes of the above embodiments are not limited here.

[0061] According to Figure 2 and Figure 4 As shown in some specific embodiments, the exhaust and suction member 32 includes a housing 322 and a cover plate 323. The air cavity 321 is formed in the housing 322, and the cover plate 323 is detachably covered on the housing 322 to block the air cavity 321.

[0062] Specifically, the air cavity 321 is formed by connecting the housing 322 and the cover plate 323. Since the cover plate 323 is detachably covered on the housing 322, this arrangement facilitates the disassembly or assembly of the overall structure. For example, during production, the various parts can be first installed in the housing 322, and then the cover plate 323 is covered on the housing 322 to form a complete exhaust and suction member 32. In this way, it is convenient for later maintenance and repair. If the rubber sleeve 31 in the air cavity 321 is damaged, the cover plate 323 can be removed from the housing 322, and the rubber sleeve 31 can be directly taken out from the air cavity 321.

[0063] It can be understood that the housing 322 of the foregoing embodiment is provided with a threaded hole, and the cover plate 323 is provided with a through hole for communicating with the threaded hole. A locking member 42 such as a bolt or a screw is simultaneously inserted into the through hole and the threaded hole to fix the cover plate 323 on the housing 322.

[0064] According to Figures 5-7As shown, the shell 322 is provided with a first cavity 3221 and a second cavity 3222, and the first cavity 3221 and the second cavity 3222 are communicated with the air cavity 321, and the utility model embodiment further includes an air inlet valve 324 and an air outlet valve 325, and the air inlet valve 324 and the air outlet valve 325 are both concave with air holes, by setting the air inlet valve 324 in the first cavity 3221, by connecting the air hole of the air outlet valve 325 with the second cavity 3222, because the air inlet valve 324 and the air outlet valve 325 are both made of silica gel material, when the external gas pressure is higher than the pressure in the air cavity 321, a pressure difference is formed, the air inlet valve 324 is affected by the external gas pressure, because the air inlet valve 324 is silica gel material, has excellent elasticity and flexibility, under the impetus of the pressure difference, the air inlet valve 324 deforms, and the air hole opens, the external gas enters the first cavity 3221 through the air hole of the air inlet valve 324, and then flows into the air cavity 321, realizing the air suction process, when the pressure in the air cavity 321 gradually rises to balance with the external pressure, the air inlet valve 324 restores to the original state under the action of the elastic force, at this time, the air hole is closed, preventing the backflow of gas, ensuring only one-way air intake process, so that the stability of the gas in the flow process is improved.

[0065] According to Figure 4 As shown, in further embodiments, the end face of the cover plate 323 is concave with a positioning groove 3231; the rubber sleeve 31 is provided with a positioning part 312, and the positioning part 312 is inserted into the positioning groove 3231.

[0066] Specifically, by inserting the positioning part 312 into the positioning groove 3231, the positioning part 312 can be accurately inserted into the positioning groove 3231 of the cover plate 323, so that the rubber sleeve 31 can be quickly and accurately assembled at the specified position during installation, ensuring the relative position accuracy between the rubber sleeve 31 and the cover plate 323, thereby ensuring the assembly accuracy of the entire air suction structure, and after the positioning part 312 is inserted into the positioning groove 3231, a close fit is formed between the two to increase the contact area between the rubber sleeve 31 and the cover plate 323, and this close fit can effectively prevent the rubber sleeve 31 from shifting or shaking relative to the cover plate 323 during use, thereby enhancing the stability of the connection between the rubber sleeve 31 and the cover plate 323.

[0067] It can be understood that the positioning groove 3231 of the utility model embodiment is annular, and correspondingly, the positioning part 312 is annular.

[0068] In some specific embodiments, the driver 1 is a motor, and the power output shaft of the motor is sleeved with an eccentric wheel, and the eccentric wheel is provided with a connecting shaft, and one end of the transmission rod 2 is sleeved outside the connecting shaft.

[0069] Specifically, by setting the eccentric sleeve on the motor power output shaft, since the geometric center of the eccentric and the rotation center of the motor power output shaft are not coincident, when the motor power output shaft rotates, the eccentric can be driven to perform eccentric circular motion, the connecting shaft of the eccentric performs eccentric circular motion together with the eccentric, and one end of the transmission rod 2 is sleeved outside the connecting shaft, the connecting shaft is used for transmitting the motion of the eccentric to the transmission rod 2, so when the connecting shaft is driven by the eccentric, the motion track of the connecting shaft is eccentric circle with the motor power output shaft as the center, and since the transmission rod 2 is sleeved on the connecting shaft, the transmission rod 2 can only perform linear motion in a certain direction, so when the connecting shaft performs eccentric circular motion, an acting force is applied to the transmission rod 2 to make the transmission rod 2 move linearly and reciprocally in the specified direction, and the linear reciprocating motion of the transmission rod 2 can directly affect the volume change of the air cavity 321; for example, when the transmission rod 2 moves outward (away from the rubber sleeve 31), the volume in the air cavity 321 increases, at this time, air enters the air cavity 321, so that the air suction effect is realized; conversely, when the transmission rod 2 is pushed to move in the opposite direction, air can be discharged.

[0070] The specific structure of the adsorption structure provided in the embodiment of the utility model is described in detail below, and the air suction and exhaust structure in any of the above embodiments is arranged in the adsorption structure.

[0071] Specifically, the bottom of the adsorption structure is provided with an adsorption disc for directly contacting the adsorbed object (such as a table top, a wall, etc.). The air suction and exhaust structure is provided with an air suction and exhaust structure for changing the air pressure in the adsorption disc, so as to realize the functions of fixing and releasing the adsorption disc on the adsorbed object. In this way, the adsorption disc is tightly adsorbed on the surface of the adsorbed object to fix the mobile phone support, or the adsorption force of the adsorption disc on the surface of the adsorbed object is weakened, so that the mobile phone support can be easily taken out.

[0072] The above is only a specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the utility model, and these modifications or replacements should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
