Description

Technical Field

[0001] The utility model belongs to the technical field of locking mechanisms, and in particular relates to a press locking structure and a selfie stick. Background Art

[0002] As a common mechanical structure, the locking mechanism can assist in achieving functions such as clamping objects and restricting the movement or rotation of objects. It is widely used in fields such as electronic equipment and its auxiliary accessories.

[0003] With the development of science and technology, especially the upgrading of smartphones, smartphones are now rich in various functions, especially the increasingly high pixel of their cameras, which have already carried most of the functions of daily photo and video recording. People like to use their mobile phones to take photos, live broadcasts or watch videos. In addition, most people use their mobile phones to take photos when traveling, and mobile phones have replaced the function of cameras in more and more occasions. However, mobile phone photography has certain limitations, that is, it is necessary to hold the mobile phone to take photos, and the length of the hand limits the distance between the mobile phone and the person when taking photos. Once the hand is stretched far, it is impossible to obtain a satisfactory angle and composition. At the same time, it is easy to shake the hand, making the photo unclear. In addition, if the mobile phone is held for a long time, the hand will be tired and sore, affecting the user experience.

[0004] In order to solve this problem, selfie sticks were invented. Mobile phones and other camera devices can be clamped on selfie sticks to take selfies, thus achieving a better photo-taking experience.

[0005] A traditional selfie stick usually includes a telescopic rod, a clamping device and a fixed base. The lower end of the telescopic rod is connected to the fixed base and can be used by people to hold or place on the ground. The upper end of the telescopic rod is rotatably connected to the clamping device, so as to adjust the height and rotation angle of the clamping device to provide people with a wider shooting angle. However, the existing telescopic rod controls the telescopic rod through the fixed base to achieve a rotation locking function, that is, a locking mechanism is provided on the fixed base to control the rotation locking of the telescopic rod, and the fixed base is also compatible with the control of a tripod support structure, which results in a relatively complex structural setting, inconvenient operation, and low efficiency of use, which is inconvenient to a certain extent. Summary of the invention

[0057] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0058] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0059] Embodiment 1:

[0060] In order to solve the problems of the relative rotation function between the telescopic rod and the clamping device of the selfie stick in the prior art, the telescopic rod is controlled by a locking mechanism arranged in a fixed base to achieve a rotation locking function, which has complex structure, inconvenient operation, low efficiency, etc., and a push locking structure is provided.

[0061] Please see attached Figure 1-2 The push-locking structure of the utility model includes: a locking body 10, a locking component 20 and a limiting component 30.

[0062] The locking body 10 has an active cavity, and a first locking portion 101 is arranged in the active cavity.

[0063] The locking assembly 20 is nested and installed in the active cavity of the locking body 10 , and can reciprocate along the axial direction of the locking body 10 in the active cavity to achieve locking or unlocking with the locking body 10 .

[0064] Specifically, the locking assembly 20 is provided with a second locking portion 2021. When the locking assembly 20 moves upward to the maximum distance, the locking assembly 20 is locked with the first locking portion 101 of the locking body 10 through the second locking portion 2021. In the locked state, the second locking portion 2021 is locked with the first locking portion 101. It can also be understood that the second locking portion 2021 is clamped with the first locking portion 101, so that the locking assembly 20 and the locking body 10 are radially fixed and cannot rotate relative to each other in the horizontal direction; when the locking assembly 20 moves upward a short distance or downward, the locking assembly 20 is unlocked with the first locking portion 101 of the locking body 10 through the second locking portion 2021. In the unlocked state, the second locking portion 2021 and the first locking portion 101 are staggered up and down so that the locking assembly 20 can rotate in the horizontal direction relative to the locking body 10.

[0065] The upper end of the limit assembly 30 is embedded in the active cavity of the locking body 10 and connected to the locking body 10. The limit assembly 30 has a first reset cavity, which accommodates the locking assembly 20 and limits the axial movement distance of the locking assembly 20. When the locking assembly 20 is in a locked state, the limit assembly 30 can be in a locked state synchronously with the locking assembly 20. When the locking assembly 20 is in an unlocked state, the limit assembly 30 can rotate synchronously with the locking assembly 20.

[0066] This embodiment is a preferred embodiment, and the locking assembly 20 includes: a pressing member 201, a locking member 202 and a rotating member 203. The locking member 202 has a second reset cavity. The rotating member 203 is installed in the second reset cavity through the first elastic member 204 and can reciprocate axially along the second reset cavity. The pressing member 201 is fixedly connected to the upper end of the locking member 202. The rotating member 203 cooperates with the pressing member 201 and can reciprocate axially along the second reset cavity and rotate in the second reset cavity during the pressing process of the pressing member 201. The second locking portion 2021 is arranged on the outer wall of the upper end of the locking member 202.

[0067] That is, during the downward pressing process, the pressing member 201 forces the rotating member 203 to move downward in the second reset chamber while also rotating. After the pressing member 201 finishes the pressing operation, the rotating member 203 moves upward during the reset process of the first elastic member 204. The locking member 202 moves synchronously with the pressing member 201 to achieve locking or unlocking with the locking body 10.

[0068] In some optional embodiments, the first locking portion 101 includes a plurality of first limiting grooves arranged on the surface of the first limiting portion 102 opposite to the locking member 202, and the second locking portion 2021 includes a plurality of first limiting protrusions arranged on the outer wall of the upper end portion of the locking member 202 and matching the first limiting grooves, and the first limiting protrusions can be embedded in the first limiting grooves so that the locking member 202 is locked with the locking body 10; or, the first locking portion 101 includes a plurality of second limiting protrusions extending in the direction of the locking member 202 on the surface of the first limiting portion 102 opposite to the locking member 202, and the second locking portion 2021 includes a plurality of second limiting grooves arranged on the outer wall of the upper end portion of the locking member 202 and matching the second limiting protrusions, and the second limiting protrusions can be embedded in the second limiting grooves so that the locking member 202 is locked with the locking body 10.

[0069] In some optional embodiments, it can also be set as follows: the first locking part 101 includes a plurality of first limiting grooves and second limiting protrusions connected end to end, and the second locking part 2021 includes a plurality of first limiting protrusions and second limiting grooves connected end to end, the first limiting groove corresponds to the first limiting protrusion, the second limiting protrusion corresponds to the second limiting groove, the first limiting protrusion is embedded in the first limiting groove and / or the second limiting protrusion is embedded in the second limiting groove, so as to realize the locking of the locking assembly 20 and the locking body 10.

[0070] The limiting assembly 30 includes: a limiting plate 301 and a limiting sleeve 302 provided with a first reset cavity. The limiting plate 301 is fixedly connected to the upper end of the limiting sleeve 302, and the limiting plate 301 is located between the pressing piece 201 and the locking piece 202; the lower end of the locking piece 202 is embedded in the first reset cavity through the second elastic piece 205 and can reciprocate axially along the first reset cavity with the cooperation of the pressing piece 201.

[0071] That is, the end of the limiting sleeve 302 opposite to the limiting plate 301 is fixedly connected to the limiting plate 301 by passing through the connecting structure of the locking member 202, or, the surface of the limiting plate 301 opposite to the limiting sleeve 302 is fixedly connected to the limiting sleeve 302 by passing through the connecting structure of the locking member 202, so that the pressing member 201, the locking member 202, the limiting plate 301 and the limiting sleeve 302 move synchronously in the radial direction.

[0072] And considering that the lower end of the locking member 202 is embedded in the first reset cavity of the limiting sleeve 302 through the second elastic member 205 and can make axial reciprocating motion along the first reset cavity with the cooperation of the pressing member 201, the height of the connecting structure between the limiting sleeve 302 and the limiting plate 301 can limit the maximum axial movement distance of the locking member 202.

[0073] like Figure 3-4As shown, this embodiment can be understood as follows: the locking body 10 is fixed, the limiting assembly 30 is installed in the locking body 10, the limiting plate 301 and the limiting sleeve 302 of the limiting assembly 30 are fixedly connected, the limiting plate 301 and the limiting sleeve 302 are respectively located at the upper and lower ends of the active cavity of the locking body 10, and the locking body 10 limits the axial installation position of the limiting plate 301 and the limiting sleeve 302, so that the axial position of the active cavity of the locking body 10 is fixed; the locking assembly 20 is nested and installed in the active cavity of the locking body 10, the pressing piece 201 of the locking assembly 20 is located above the limiting plate 301, and the locking piece 202 is located between the limiting plate 301 and the limiting sleeve 302 and embedded in the limiting sleeve In the first reset cavity of the cylinder 302, it can also be understood that the limit plate 301 is located between the pressing member 201 and the locking member 202, and the pressing member 201 and the locking member 202 are fixedly connected. The locking member 202 moves synchronously with the pressing member 201 in the axial direction during the pressing process of the pressing member 201. During the rotation of the rotating member 203, when the locking member 202 reaches the maximum axial movement distance, it is locked with the locking body 10, and the locking assembly 20 and the limit assembly 30 are synchronously in a locked state. When the locking member 202 moves a short distance in the axial direction or moves downward, it is unlocked with the locking body 10, and the locking assembly 20 and the limit assembly 30 can rotate synchronously relative to the locking body 10.

[0074] The push-lock structure provided in this embodiment uses the limit assembly 30 to limit the axial movement distance of the locking assembly 20, so that it can be locked or unlocked with the locking body 10 during the axial reciprocating movement, thereby enabling the locking assembly 20 to drive the limit assembly 30 to be locked or rotated in the horizontal direction relative to the locking body 10. The push-lock structure is arranged at the end where the clamping device of the selfie stick is located, and has a simple structure, convenient operation, and high utilization rate.

[0075] Embodiment 2:

[0076] This embodiment discloses a push-locking structure, which optimizes the specific structure of the locking component and the limiting component and the matching relationship between the locking component and the limiting component on the basis of Embodiment 1.

[0077] Specifically, the specific structure of the locking assembly 20 is as follows: Figure 5-7 As shown, the opposite surface of the pressing member 201 to the locking member 202 extends a first guide portion 2011 in the direction of the locking member 202, and the opposite end of the rotating member 203 to the pressing member 201 is provided with a second guide portion 2031 matching the first guide portion 2011. When the pressing member 201 is pressed downward, the first guide portion 2011 cooperates with the second guide portion 2031, and forces the rotating member 203 to rotate while driving the rotating member 203 to move downward.

[0078] Specifically, the end of the first guide portion 2011 extends a plurality of first teeth 2012 toward the locking member 202, and the plurality of first teeth 2012 are distributed in a ring shape. The end of the second guide portion 2031 opposite to the pressing member 201 extends a plurality of second teeth 2032 toward the pressing member 201, and the plurality of second teeth 2032 are distributed in a ring shape. The number, shape and size of the first teeth 2012 and the second teeth 2032 correspond. When the pressing member 201 is pressed downward, the first teeth 2012 and the second teeth 2032 abut against each other, thereby forcing the rotating member 203 to rotate and also forcing the rotating member 203 to move downward.

[0079] In addition, a third guide portion 2013 is provided on the outer wall of the first guide portion 2011 along the movement direction of the pressing member 201, and a fourth guide portion 2033 having the same structure as the third guide portion 2013 is provided on the outer wall of the second guide portion 2031 along the movement direction of the second guide portion 2031. During the rotation of the rotating member 203, the fourth guide portion 2033 and the third guide portion 2013 can correspond to each other, so that the locking assembly 20 reaches the maximum displacement during the upward movement, and when the locking assembly 20 reaches the maximum displacement during the upward movement, it is locked with the locking body 10.

[0080] In some optional embodiments, the third guide portion 2013 and the fourth guide portion 2033 can both be guide grooves or guide strips arranged along the axial direction, and the number of the third guide portion 2013 and the fourth guide portion 2033 is the same and is respectively smaller than the number of the first teeth 2012 and / or the second teeth 2032. Therefore, the pressing member 201 needs to be pressed at least twice to enable the rotating member 203 to rotate to the fourth guide portion 2033 and the third guide portion 2013 to correspond.

[0081] For example, assuming that the number of the first teeth 2012 and the number of the second teeth 2032 are set to 6 respectively, then when the pressing member 201 is pressed once, the rotating member 203 can rotate 60°, and the number of the third guide portion 2013 and the fourth guide portion 2033 are set to 3 respectively, the rotating member 203 needs to rotate 120° to make the fourth guide portion 2033 correspond to the third guide portion 2013, that is, the pressing member 201 needs to be pressed twice to achieve this.

[0082] The fixing structure of the pressing member 201 and the locking member 202 is as follows: a first stud 2022 extends from the surface of the locking member 202 opposite to the pressing member 201 in the direction of the pressing member 201 , and the pressing member 201 is fixedly connected to the locking member 202 by a first fixing screw 2014 .

[0083] The specific structure of the limiting component 30 is as follows: Figure 8-9As shown, the limiting plate 301 extends an annular limiting cylinder 3011 toward the locking member 202 , and the annular limiting cylinder 3011 can be embedded in the reset cavity of the locking member 202 . The upper end of the rotating member 203 is embedded in the annular limiting cylinder 3011 and can reciprocate axially along the annular limiting cylinder 3011 .

[0084] A fifth guide portion 3012 is axially provided on the inner wall of the annular limiting cylinder 3011 , and the fifth guide portion 3012 can cooperate with the pressing member 201 and the rotating member 203 to limit the movement distance of the locking assembly 20 , thereby controlling the locking or unlocking state of the locking assembly 20 .

[0085] Specifically, the fifth guide portion 3012 matches the third guide portion 2013 and the fourth guide portion 2033, that is, when the third guide portion 2013 and the fourth guide portion 2033 are guide grooves, the fifth guide portion 3012 is a guide bar that can be embedded in the guide grooves; when the third guide portion 2013 and the fourth guide portion 2033 are guide bars, the fifth guide portion 3012 is a guide groove in which the guide bar can be embedded.

[0086] The axial movement process of the locking assembly 20 is that the third guide portion 2013 and the fifth guide portion 3012 are nested so that the pressing member 201 moves axially along the fifth guide portion 3012 through the third guide portion 2013, and when the rotating member 203 rotates to correspond to the fourth guide portion 2033 and the third guide portion 2013 during the pressing process of the pressing member 201, the fourth guide portion 2033 can also move axially along the fifth guide portion 3012, thereby making the rotating member 203 move upward to the maximum distance during the resetting process of the first elastic member 204, and further making the locking member 202 move upward to the maximum distance during the resetting process of the second elastic member 205, thereby achieving locking with the locking body 10.

[0087] In some optional embodiments, the mounting structure between the limiting assembly 30 and the locking body 10 and the mounting structure between the locking assembly 20 and the limiting assembly 30 are further disclosed.

[0088] The connection structure between the limiting assembly 30 and the locking assembly 20 is as follows: a plurality of first through holes 3013 for the first studs 2022 to pass through are provided on the limiting plate 301 , and the first studs 2022 of the locking member 202 pass through the first through holes 3013 and are fixed to the pressing member 201 by the first fixing screws 2014 .

[0089] A second stud 3022 extends from the surface of the limiting sleeve 302 opposite to the limiting plate 301 toward the limiting plate 301, and a plurality of second through holes 2023 are provided on the upper end surface of the locking member 202 for the second stud 3022 to pass through. The second stud 3022 of the limiting sleeve 302 passes through the second through holes 2023 and is fixed to the limiting plate 301 by a second fixing screw 3014.

[0090] The assembly structure of the limiting component 30, the locking component 20 and the locking body 10 is as follows: a first limiting portion 102 and a second limiting portion 103 are provided on the inner wall of the accommodating cavity of the locking body 10, the limiting plate 301 is provided above the first limiting portion 102 and between the pressing member 201 and the locking member 202, the first locking portion 101 is provided on the surface of the first limiting portion 102 opposite to the locking member 202, and the limiting sleeve 302 is provided below the second limiting portion 103.

[0091] The first limiting portion 102 and the second limiting portion 103 can be used to limit the distance between the limiting plate 301 and the limiting sleeve 302 .

[0092] In some optional embodiments, the second limiting portion 103 is configured as a first annular groove, and an annular limiting protrusion 3021 that can be embedded in the first annular groove extends from the upper end surface of the limiting sleeve 302, thereby limiting the limiting sleeve 302 in the radial direction so that it can only rotate along the first annular groove and cannot shake.

[0093] In addition, in some optional embodiments, a second annular groove 1021 is provided on the upper end surface of the first limiting portion 102 to limit the pressing member 201 in the radial direction.
