[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.

[0028] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.

[0029] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0030] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a positioning assembly, which is arranged between the first adjusting member 2 and the second adjusting member 3 whose relative positions need to be adjusted. It should be noted that the first adjusting member 2 and the second adjusting member 3 are used to represent any two objects whose relative positions need to be adjusted. For example, if the positioning assembly is used on a laptop computer, since the position between the display screen and the body of the laptop computer needs to be adjusted, when the positioning assembly is arranged between the display screen and the body, the first adjusting member 2 can be the display screen, and the second adjusting member 3 can be the body. Of course, the two can also be interchangeable. In order to realize the rotational connection between the first adjusting member 2 and the second adjusting member 3, it is usually adopted that a connecting shaft 21 is provided on the first adjusting member 2, and a connecting hole 31 is provided on the second adjusting member 3. It can also be that a connecting hole is provided on the first adjusting member 2, and a connecting shaft is provided on the second adjusting member 3, as long as the connecting shaft is movably inserted into the connecting hole. It can be understood that the rotational connection between the first adjusting member 2 and the second adjusting member 3 can also be other structures, and the installation and function of the positioning assembly can be realized. In the embodiment of the utility model, in order to clearly describe the structure and working principle of the positioning assembly, the movable connection between the first adjusting member 2 and the second adjusting member 3 is set as an example of the matching connection between the connecting shaft 21 and the connecting hole 31, and the rotational connection between the first adjusting member 2 and the second adjusting member 3 is not limited.

[0031] like Figure 1 and Figure 2As shown, in the embodiment of the utility model, the positioning assembly includes a pressing member 11 and a friction member 12. The pressing member 11 is connected to the connecting shaft 21 through a connecting structure, and a friction zone 14 is formed between the pressing member 11 and the second adjusting member 3. The friction member 12 is arranged in the friction zone 14, and abuts against the pressing member 11 and the second adjusting member 3 respectively. Specifically, after the connecting shaft 21 is inserted into the connecting hole 31, the pressing member 11 is connected to the connecting shaft 21. The pressing member 11 can be a plate-shaped member. After being connected to the connecting shaft 21, the pressing member 11 covers the connecting shaft 21 and extends toward the edge of the connecting hole 31, and a friction zone 14 is formed between the pressing member 11 and the second adjusting member 3, that is, the pressing member 11 also covers part of the second adjusting member 3 to form the friction zone 14. The friction member 12 is arranged in the friction zone 14, and abuts against the pressing member 11 and the second adjusting member 3 respectively, so that there is a certain amount of friction between the pressing member 11 and the friction member 12, and between the second adjusting member 3 and the friction member 12. The friction member 12 is made of a material with good wear resistance and high friction performance (such as rubber or silicone that can undergo elastic deformation). Therefore, it can undergo elastic deformation under the extrusion of the pressing member 11, and always maintain contact with the pressing member 11 and the second adjusting member 3, thereby generating a large friction force, realizing the rotation adjustment between the first adjusting member 2 and the second adjusting member 3 and the stable maintenance of the adjustment position, and the adjustment position will not change arbitrarily.

[0032] The position adjustment assembly provided in the embodiment of the utility model not only realizes the rotation adjustment between the first adjustment member 2 and the second adjustment member 3 by using the cooperation between the pressing member 11 and the friction member 12, but also the rotation position can be stably maintained and will not change at will, which well meets the use requirements of the rotation adjustment between the first adjustment member 2 and the second adjustment member 3. In addition, the position adjustment assembly has a simple structure and low production cost. At the same time, during installation, it only needs to place the friction member 12 between the pressing member 11 and the second adjustment member 3, and then connect the pressing member 11 to the connecting shaft 21 on the first adjustment member 2. The installation steps are simple and the design is ingenious.

[0033] like Figure 1 and Figure 3 As shown, in some embodiments, a mounting groove 15 may be provided on the pressing member 11 and / or the second adjusting member 3, and the friction member 12 may be arranged in the mounting groove 15. This design enables the friction member 12 to fully contact the inner wall of the mounting groove 15, thereby increasing the contact area between the friction member 12 and the pressing member 11 and the second adjusting member 3, and the friction member 12 is not easily misaligned with the relative rotation of the first adjusting member 2 and the second adjusting member 3, thereby providing a more stable friction force to maintain the relative position between the first adjusting member 2 and the second adjusting member 3, and improving the stability of the adjustment.

[0034] Understandably, Figure 3The mounting groove 15 shown is exemplarily opened on the second adjusting member 3. In some other embodiments, the mounting groove 15 can also be opened on the clamping member 11, or opened on the clamping member 11 and the second adjusting member 3 at the same time. The above methods can achieve reliable positioning of the friction member 12, and then reliably achieve the function of on-demand adjustment and stable positioning of the relative position between the first adjusting member 2 and the second adjusting member 3.

[0035] In some embodiments, the mounting groove 15 is arranged around the connecting hole 31, so the friction member 12 arranged in the mounting groove 15 can be an annular structure with the same shape as the mounting groove 15, and can be a circular ring, which has good stability during rotation adjustment. Moreover, the cross-sectional shape of the friction member 12 in the radial direction can be circular or quadrilateral, etc., and the cross-sectional shape of the mounting groove 15 in the radial direction also keeps matching, so that the friction member 12 can be stable in the mounting groove 15 and will not loosen.

[0036] like Figure 2 and Figure 3 As shown, in some embodiments, the positioning assembly further includes a limit block 16 and a limit groove 17, and the limit block 16 is located in the limit groove 17; wherein, the limit block 16 is arranged on the first adjusting member 2, and the limit groove 17 is provided on the second adjusting member 3; or the limit groove 17 is provided on the first adjusting member 2, and the limit block 16 is arranged on the second adjusting member 3. Specifically, in the circumferential rotation direction, the limit groove 17 is not continuously arranged in a circular ring structure, but is partially discontinuous to achieve positioning, and the range of the limit groove 17 in the circumferential direction is determined according to actual use requirements. For example, if it is necessary to enable the first adjusting member 2 and the second adjusting member 3 to rotate within a range of about 270°, the corresponding range of the limit groove 17 in the circumferential direction is about 270°, and the remaining part is a solid structure and can interact with the limit block 16 to prevent the limit block 16 from continuing to rotate to achieve the purpose of positioning. Through the above design, the limit block 16 rotates in the limit groove 17 and can be limited by the two ends of the limit groove 17 in the circumferential direction, so that the first adjustment member 2 and the second adjustment member 3 can rotate and adjust the relative position within a set range. When adjusted to the limit position, the limit block 16 abuts against the inner wall of the end of the limit groove 17 in the circumferential direction, thereby playing a role of limiting and prompting the user, avoiding the problem of damage to related components due to excessive adjustment, and improving the convenience and reliability of use.

[0037] like Figure 1 and Figure 3As shown, in some embodiments, the positioning assembly further includes a gasket 18, which is disposed between the first adjusting member 2 and the second adjusting member 3, so as to avoid direct contact between the first adjusting member 2 and the second adjusting member 3 at the position where the gasket 18 is disposed. The gasket 18 has a buffering effect between the first adjusting member 2 and the second adjusting member 3, and is usually made of a material with good wear resistance, so that when the first adjusting member 2 and the second adjusting member 3 are rotated and adjusted, the direct collision and friction between the two can be reduced to reduce collision noise, and at the same time, the first adjusting member 2 and the second adjusting member 3 can be prevented from being damaged or the gap widened due to direct wear, thereby improving durability.

[0038] like Figure 2 and Figure 3 As shown, in some embodiments, the connection structure includes a connection piece (not shown in the figure), a first connection hole 131 provided on the pressing piece 11, and a second connection hole 132 provided on the connecting shaft 21, and the connection piece passes through the first connection hole 131 and extends into the second connection hole 132 for fixed connection. Specifically, the first connection hole 131 is a through hole provided through the pressing piece 11, and the second connection hole 132 can be a through hole or a blind hole, so that the connection piece at least completely passes through the first connection hole 131 for fixed connection. Optionally, the connection piece can be a structure such as a screw, a bolt, a snap, etc. When the connection piece is a threaded fastener such as a screw or a bolt, an internal thread can be correspondingly provided in the second connection hole 132, or a nut can be provided at the second connection hole 132. The specific connection method of the connection structure is not further limited, and it only needs to be able to be connected to the connection piece to achieve the function of connecting the pressing piece 11 with the connecting shaft 21.

[0039] like Figure 4 As shown, the embodiment of the utility model also provides a vertical hair dryer 4, including a fan head 41 for generating airflow, a support rod 42 for supporting the fan head 41, and the above-mentioned adjustment component; the fan head 41 is connected to the support rod 42, and the adjustment component is arranged between the fan head 41 and the support rod 42; wherein, when the above-mentioned adjustment component is arranged on the vertical hair dryer 4, the first adjustment member 2 can be the fan head 41, the second adjustment member 3 can be the support rod 42, or the first adjustment member 2 can be the support rod 42, and the second adjustment member 3 can be the fan head 41. In this way, the rotation adjustment between the fan head 41 and the support rod 42 can be realized by providing the adjustment component, and the position can be kept stable and will not change after the rotation adjustment. At the same time, the vertical hair dryer 4 provides support for the fan head 41 through the support rod 42, and does not need to be held during use, freeing the user's hands, and is convenient and flexible to use, which greatly improves the user's actual use experience.

[0040] In some embodiments, the depth of the connection hole 31 can be set to be greater than or equal to the length of the connection shaft 21. When the above design is adopted, the connection shaft 21 can be completely inserted into the connection hole 31, achieving a tight fit without leaving gaps, improving the aesthetics of the connection, and reducing the problem of dirt and grime hiding in the connection. At the same time, it can also prevent the end face of the excessively long connection shaft 21 from generating a reaction force on the pressing member 11, thereby reducing the extrusion force generated by the pressing member 11 on the friction member 12, so that the damping effect generated by the friction member 12 between the first adjustment member 2 and the second adjustment member 3 is reduced, resulting in a situation where the effect of rotational positioning between the first adjustment member 2 and the second adjustment member 3 is deteriorated. With this setting, the pressing member 11 can reliably press the friction member 12, so that there is a good damping effect between the first adjustment member 2 and the second adjustment member 3, the hand feel is good during rotation adjustment, and reliable positioning can be achieved.

[0041] like Figure 3 and Figure 4 As shown, in some embodiments, a first wire hole 43 is provided on the pressing member 11, and a second wire hole 44 is provided on the connecting shaft 21, and the first wire hole 43 and the second wire hole 44 are coaxially arranged. The first wire hole 43 and the second wire hole 44 are arranged to allow the wires connecting the blower head 41 and the support rod 42 to pass through to achieve electrical connection. Through the above design, when the blower head 41 and the support rod 42 are rotated and adjusted, the wires inside the vertical hair dryer 4 will not be affected by the torsion, thereby avoiding damage to the circuit due to the adjustment, and ensuring the reliability of the use of the vertical hair dryer 4.

[0042] like Figure 4 As shown, in some embodiments, the fan head 41 includes a shell 411 and a fan assembly (not shown in the figure) arranged in the shell 411, and the shell 411 is respectively provided with an air inlet (not shown in the figure) and an air outlet 4111, and the fan assembly sucks in air from the air inlet and discharges it from the air outlet 4111; wherein, when the shell 411 is the first adjusting member 2, the second adjusting member 3 is the support rod 42; or when the shell 411 is the second adjusting member 3, the first adjusting member 2 is the support rod 42.

[0043] like Figure 4 As shown, in some embodiments, the vertical hair dryer 4 further includes a noise reduction net 45, which is arranged at the air inlet and connected to the housing 411. The noise reduction net 45 has a plurality of meshes. In this design, the meshes of the noise reduction net 45 allow outside air to enter the housing 411, and other solid parts forming the meshes can block a part of the noise generated by the fan assembly from being transmitted through the air inlet, thereby achieving the noise reduction effect of the hair dryer and improving the comfort of use.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
