[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] like Figure 1-5 As shown in the figure, the adapter barrel for a telescopic lens camera according to this embodiment of the present invention includes an adapter barrel body 100. The length of the adapter barrel body 100 is greater than the telescopic stroke of the telescopic lens camera, and its outer end (i.e., front end) has a filter connecting part 101. The filter connecting part 101 can be an external thread or an internal thread, used to install filters with different functions at the front end of the adapter barrel body 100; the inner end (i.e., rear end) of the adapter barrel body 100 has a mounting surface. The mounting part 102 protrudes towards the axis of the adapter barrel body 100 and extends along the inner edge of the adapter barrel body 100. By rotating the adapter barrel body 100 with the mounting part 102, it is locked into the slot 201 provided with the telescopic lens camera 200, thus assembling the adapter barrel body 100 onto the telescopic lens camera 200. Rotating the adapter barrel body 100 in the opposite direction separates the mounting part 102 from the slot 201, allowing the adapter barrel body 100 to be disassembled. This new adapter barrel allows for filter installation without altering the structure of the telescopic lens camera, meeting various shooting needs and offering strong versatility.

[0019] For example Figure 1-5As shown, the outer surface of the mounting clip 102 in this embodiment of the present invention is provided with a locking hole 103. When the adapter barrel body 100 is assembled to the telescopic lens camera 200, the decorative ring mounting ball 202 (which is a telescopic positioning ball that is already available on the market, and its structure and working principle will not be described in detail here) of the telescopic lens camera 200 is first compressed inward by the mounting clip 102. Then, the adapter barrel body 100 is rotated until the mounting clip 102 is engaged in the slot 201. At this time, the decorative ring mounting ball 202 bounces outward to reset and engages in the locking hole 103, thereby locking the adapter barrel body 100. This improves the assembly stability and reliability of the adapter barrel body 100 and the telescopic lens camera 200, avoids the risk of the adapter barrel body 100 falling off due to accidental twisting, and improves the safety of use. Moreover, the adapter barrel is locked by using the decorative ring mounting ball 202 of the telescopic lens camera 200, which is ingenious and also ensures the universality of the adapter barrel.

[0020] Furthermore, the outer surface of the adapter barrel body 100 of this utility model is also provided with an unlocking mechanism 104 for pressing down the decorative ring assembly ball 202 to unlock the adapter barrel body 100. The specific structure of the unlocking mechanism 104 is as follows: the unlocking mechanism 104 includes an unlocking key 105, an unlocking lever 106, and an elastic element 107; the unlocking key 105 is disposed on the outer surface of the adapter barrel body 100 and can move along the axial direction of the adapter barrel body 100. Specifically, the outer surface of the adapter barrel body 100 is provided with an assembly hole 108, the assembly hole 108 is provided with a slide rail 109, and the bottom of the unlocking key 105 is provided with a sliding connection part 110. The connecting part 110 is slidably connected to the slide rail 109, allowing the unlocking key 105 to be movably mounted on the outer surface of the adapter barrel body 100 along the axial direction of the adapter barrel body 100. More specifically, the mounting hole 108 has two parallel and spaced slide rails 109, and the bottom of the unlocking key 105 has two spaced sliding connecting parts 110. Both sliding connecting parts 110 are hooks with barbs at the ends, arranged symmetrically on the left and right, and can slide back and forth to hook onto the two slide rails 109 respectively. This structure ensures both the assembly stability of the unlocking key 105 and the adapter barrel body 100 and good movement performance of the unlocking key 105.

[0021] The unlocking lever 106 is arranged along the axial direction of the adapter barrel body 100 and connected to the unlocking key 105. The elastic element 107 is assembled on the unlocking lever 106, driving the unlocking lever 106 and the unlocking key 105 to reset. Specifically, the bottom of the unlocking key 105 is also provided with a mounting base 111. The other end of the unlocking lever 106 is mounted on the mounting base 111. For example, the mounting base 111 is located in the middle of the two sliding connecting parts 110 and is provided with a insertion hole. The other end of the unlocking lever 106 is installed in the insertion hole. The elastic element 107 is a spring, which is sleeved on the unlocking lever 106. Preferably, the sliding connecting part 110 and the mounting base 111 are integrally formed with the unlocking key 105, which can further improve the assembly stability and reliability of the unlocking key 105 and the adapter barrel body 100. For example, the sliding connecting part 110 and the mounting base 111 are integrally injection molded on the bottom of the unlocking key 105.

[0022] When unlocking the adapter barrel body 100, push the unlock button 105 along the axis of the adapter barrel body 100 toward the telescopic lens camera 200. This drives one end of the unlocking lever 106 to extend into the locking hole 103 and press down the decorative ring mounting ball 202, causing the decorative ring mounting ball 202 to disengage from the locking hole 103, thus completing the unlocking. Then, rotate the adapter barrel body 100 to disassemble the adapter barrel of this utility model. The unlocking operation is easy and simple. Moreover, the inward (i.e., toward the telescopic lens camera 200) push unlocking method is not only beneficial for unlocking the unlock button 105 when holding the camera, but also avoids the risk of the rotating barrel falling when pushing it outward to unlock and disassemble the rotating barrel, thus improving operational safety.

[0023] like Figure 1 , 2 As shown in Figures 4 and 5, in this embodiment of the present invention, the unlocking button 105 has an unlocking operation part 112 at one end away from the filter connection part 101. The unlocking operation part 112 has an arc-shaped operation surface 113. The arc-shaped operation surface 113 smoothly transitions with the surface of the unlocking button 105 to form a finger pressure operation position 114, which further improves the comfort of the unlocking operation and facilitates the unlocking operation. Preferably, the unlocking operation part 112, the arc-shaped operation surface 113, and the finger pressure operation position 114 are integrally formed with the unlocking button 105. For example, the unlocking operation part 112, the arc-shaped operation surface 113, and the finger pressure operation position 114 are integrally injection molded with the unlocking button 105, which simplifies the structure.

[0024] For example Figure 1 , 2 As shown in Figures 4 and 5, the outer surface of the adapter barrel body 100 in this embodiment of the present invention is provided with an unlocking operation indicator 115 and an installation alignment indicator 116. The unlocking operation indicator 115 is located beside the unlocking button 105 of the unlocking mechanism 104, and can be composed of at least one of icons, patterns, and text, for example... Figure 1 The unlocking operation indicator 115 consists of an arrow icon, a lock pattern, and the word "unlock," which helps users clearly understand the direction of the adapter barrel's unlocking operation. During the initial screwing and assembly of the adapter barrel body 100, by aligning the installation alignment mark 116 with the unlocking position mark 203 on the telescopic lens camera 200, the adapter barrel can be quickly and accurately aligned, further improving the convenience of the installation operation and making assembly more efficient.

[0025] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
