[0011] Optionally, the side wall of the fastener is provided with a locking groove, and the locking block is disposed in the locking groove.
[0012] Optionally, the locking structure further includes a control button, which is movably disposed on the fixing member. When the control button is driven to move toward the fixing member, the control button drives the second segment to slide within the sliding space.
[0013] Optionally, the control button includes a slide rod and a pressing base. One end of the slide rod is slidably disposed within the fixing member. A second elastic member is sandwiched between one end of the slide rod and the fixing member. The other end of the slide rod is at least partially exposed outside the fixing member and connected to the pressing base. The side wall of the pressing base is provided with an actuating part, which is used to drive the second segment to slide into the sliding space.
[0014] Optionally, the fixing member is provided with a first sliding groove and a second sliding groove that are connected. The bottom of the first sliding groove is provided with a third clearance opening. One end of the sliding rod passes through the third clearance opening.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0028] This utility model embodiment provides a locking structure 100, such as Figures 1 to 7 As shown, the locking structure 100 includes a fixing member 1, a movable rod 2, and a locking assembly 3. The fixing member 1 has a locking block 12 on its side wall, and the movable rod 2 has a sliding space 21 on its inner wall. The locking assembly 3 includes a locking member 31 and a first elastic member 32. The locking member 31 includes a first segment 311, a second segment 312, and a hook portion 313. The first segment 311 is slidably disposed within the sliding space 21. The second segment 312 and the hook portion 313 are respectively disposed at both ends of the first segment 311 and are both exposed outside the sliding space 21. The first elastic member 32 is located within the sliding space 21, and its two ends are respectively connected to the first segment 311 and the inner wall of the movable rod 2. The hook portion 313 locks with the locking block 12 under the elastic force of the first elastic member 32, thereby locking the movable rod 2 to the fixing member 1. When the second segment 312 is driven to slide into the sliding space 21, the hook portion 313 disengages from the locking block 12.
[0029] Specifically, the first segment 311 is slidably disposed within the sliding space 21, the second segment 312 and the locking hook 313 are respectively disposed at both ends of the first segment 311 and are both exposed outside the sliding space 21, the first elastic member 32 is located within the sliding space 21, and the two ends of the first elastic member 32 are respectively connected to the inner wall of the first segment 311 and the movable rod 2. Thus, when the locking hook 313 is engaged with the locking block 12 on the fixing member 1, the first elastic member 32 can pre-tighten the first segment 311 within the sliding space 21, so that the locking hook 313 on the first segment 311 can be stably locked onto the locking block 12 under the elastic force of the first elastic member 32, thereby locking the movable rod 2 onto the fixing member 1 and realizing the close fit and storage of the movable rod 2 and the fixing member 1, effectively preventing the movable rod 2 from accidentally dislodging from the fixing member 1 when it is accidentally touched by external force, and ensuring the stability of the storage of the movable rod 2.
[0030] Furthermore, since the second segment 312 is exposed outside the sliding space 21, it is convenient for the user to drive the second segment 312 to slide into the sliding space 21, thereby causing the first segment 311 to slide, so that the locking hook 313 disengages from the locking block 12, unlocking the movable rod 2 from the fixing member 1 for use. It can be understood that during the process of driving the second segment 312 to slide into the sliding space 21, the first elastic member 32 can be compressed, so that when the locking hook 313 disengages from the locking block 12, the first elastic member 32 can drive the locking member 31 to automatically reset.
[0031] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 6 As shown, the inner wall of the movable rod 2 is provided with an installation groove 22 and an installation block 24. The installation block 24 is located in the installation groove 22. The inner wall of the installation block 24 is recessed with a first slide rail 241. The first slide rail 241 and the installation groove 22 enclose and define a sliding space 21. The first segment 311 is slidably disposed along the first slide rail 241. The bottom of the installation groove 22 is provided with a first clearance opening 2221. The second segment 312 passes through the first clearance opening 2221. At the first clearance opening 2221, the first segment 311 abuts against the bottom of the installation groove 22.
[0032] Specifically, the inner wall of the movable rod 2 is provided with a mounting groove 22 and a mounting block 24. The mounting block 24 is located in the mounting groove 22, and the inner wall of the mounting block 24 is recessed with a first slide rail 241, so that the first slide rail 241 and the mounting groove 22 can enclose and define a stable sliding space 21, thereby ensuring that the first segment 311 can be accommodated in the first slide rail 241 and slide along the first slide rail 241. The bottom of the mounting groove 22 is provided with a first clearance opening 2221, so that the second segment 312 can pass through the first clearance opening 2221, so as to facilitate the driving of the second segment 312 to slide into the sliding space 21 when unlocking. Moreover, the first segment 311 abuts against the bottom of the mounting groove 22 at the first clearance opening 2221, thereby restricting the first segment 311 within the first slide rail 241, so as to prevent the first segment 311 from disengaging from the sliding space 21 and realize the stability of the operation of the locking member 31.
[0033] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 5 As shown, the mounting groove 22 includes a first groove 221 and a second groove 222 arranged in an L-shape. The first groove 221 is parallel to the first slide 241. The first clearance opening 2221 is located at the bottom of the second groove 222. The first section 311 abuts against the bottom of the second groove 222.
[0034] Specifically, the first groove 221 and the second groove 222 of the mounting groove 22 are arranged in an L-shape, and the first groove 221 is parallel to the first slide rail 241. Thus, the second groove 222 can be located in the sliding direction of the first segment 311, so that the first segment 311 can abut against the bottom of the second groove 222 at the first clearance opening 2221, thereby preventing the first segment 311 from sliding away from the first slide rail 241.
[0035] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 5 As shown, the second groove 222 extends outward from the first clearance opening 2221 and is provided with a second slide 2222. The second section 312 slides along the second slide 2222 and is partially exposed outside the second slide 2222.
[0036] Specifically, the second groove 222 extends outward from the first clearance opening 2221 and is provided with a second slide rail 2222. The second segment 312 slides along the second slide rail 2222. Thus, the second slide rail 2222 can guide the second segment 312, so that after driving the second segment 312, the second segment 312 can slide smoothly along the second slide rail 2222 and stably drive the first segment 311 in the sliding space 21 to slide along the first slide rail 241, thereby ensuring that the locking hook 313 can smoothly disengage from the locking block 12.
[0037] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 6 As shown, the mounting groove 22 has a mounting part 23 on the side of the groove away from the first clearance opening 2221. The mounting part 23 has a fixing hole 231. The mounting block 24 has a hook part 242, which is fixed in the fixing hole 231.
[0038] Specifically, the mounting groove 22 has a mounting part 23 on the side of the groove away from the first clearance opening 2221. The mounting part 23 has a fixing hole 231. The mounting block 24 has a hook part 242, which is fixed in the fixing hole 231. Thus, the mounting block 24 can be fixedly installed in the mounting groove 22 through the cooperation of the hook part 242 and the fixing hole 231. Compared with fixing methods such as screws, the cooperation of the hook part 242 and the fixing hole 231 allows the mounting block 24 to be quickly fixed in the mounting groove 22 and is also easy to disassemble, thereby improving the assembly efficiency of the mounting block 24. In addition, it is easy to repair when the locking member 31 and the first elastic member 32 in the sliding space 21 malfunction.
[0039] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 6 As shown, the side wall of the mounting block 24 is provided with a second clearance opening 243 that communicates with the first slide rail 241, and the locking hook part 313 is exposed outside the second clearance opening 243.
[0040] Specifically, by providing a second clearance opening 243 that communicates with the first slide rail 241 on the side wall of the mounting block 24, the locking hook portion 313 can be exposed outside the sliding space 21 through the second clearance opening 243, so that the locking hook portion 313 can be engaged with the locking block 12.
[0041] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 4 and Figure 7 As shown, the side wall of the fastener 1 is provided with a locking groove 11, and the locking block 12 is disposed in the locking groove 11.
[0042] Compared to the locking block 12 being directly set on the side wall of the fixing member 1, the locking block 12 is set in the locking groove 11, so that after the movable rod 2 is disengaged from the fixing member 1, the locking groove 11 can protect the locking block 12 and prevent the locking block 12 from being damaged.
[0043] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 4 and Figure 7 As shown, the locking structure 100 also includes a control button 4, which is movably mounted on the fixing member 1. When the control button 4 is driven to move toward the fixing member 1, the control button 4 drives the second segment 312 to slide into the sliding space 21.
[0044] By implementing this example, the user can easily and conveniently drive the locking hook 313 to disengage from the locking block 12 simply by pressing the control button 4, thereby releasing the fixation between the movable rod 2 and the fixing member 1. Specifically, when the control button 4 is pressed, the control button 4 moves toward the fixing member 1 and drives the second segment 312 of the locking member 31 to slide into the sliding space 21, so that the locking hook 313 of the locking member 31 disengages from the locking block 12 of the fixing member, thereby allowing the movable rod 2 to disengage from the fixing member and unfold.
[0045] It is worth mentioning that when the fixing member 1 is provided with multiple locking blocks 12, and the locking members 31 on the multiple movable rods 2 are all locked to the corresponding locking blocks 12 on the fixing member 1, by implementing this example, the drive control movable rod 2 button can simultaneously drive the second segment 312 of multiple locking members 31 to slide into the sliding space 21 of the corresponding movable rod 2, so as to unlock multiple movable rods 2 at the same time. There is no need to operate the second segment 312 of each locking member 31 one by one, making the unlocking operation simple and convenient, thereby improving the unlocking efficiency.
[0046] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 4 and Figure 7 As shown, the control button 4 includes a slide rod 41 and a pressing base 42. One end of the slide rod 41 is slidably disposed in the fixing member 1. A second elastic member 5 is sandwiched between one end of the slide rod 41 and the fixing member 1. The other end of the slide rod 41 is at least partially exposed outside the fixing member 1 and is connected to the pressing base 42. The side wall of the pressing base 42 is provided with an actuating part 421, which is used to drive the second segment 312 to slide into the sliding space 21.
[0047] Specifically, one end of the slide rod 41 is slidably disposed within the fixing member 1, while the other end of the slide rod 41 is at least partially exposed outside the fixing member 1 and connected to the pressing seat 42. The pressing seat 42 increases the pressing area of the control button 4, making it easier to press the control button 4. By pressing the pressing seat 42, one end of the slide rod 41 can slide into the fixing member 1, and during the sliding process, the actuating part 421 on the side wall of the pressing seat 42 can abut against the second section 312 of the locking member 31, thereby driving the locking member 31 to move, so that the locking hook part 313 disengages from the locking block 12, thereby releasing the fixing member 1 from the movable rod 2.
[0048] Furthermore, since a second elastic element 5 is sandwiched between one end of the slide rod 41 and the fixing member 1, when the pressing seat 42 is pressed to make one end of the slide rod 41 slide inward toward the fixing member 1, the slide rod 41 will compress the second elastic element 5. Thus, when the pressing seat 42 is released, the second elastic element 5 can make one end of the slide rod 41 slide outward toward the fixing member 1, so that the control button 4 can be automatically reset.
[0049] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 4 As shown, the fixing member 1 is provided with a first sliding groove 13 and a second sliding groove 14 that are connected. The bottom of the first sliding groove 13 is provided with a third clearance opening 131. One end of the sliding rod 41 passes through the third clearance opening 131. A limiting member 411 is provided on one end of the sliding rod 41. The limiting member 411 is located in the second sliding groove 14, and the width of the limiting member 411 is greater than the width of the third clearance opening 131. The other end of the sliding rod 41 is slidably arranged along the first sliding groove 13. The second elastic member 5 is provided between the other end of the sliding rod 41 and the bottom of the first sliding groove 13.
[0050] Specifically, one end of the slide rod 41 is provided with a limiting member 411, which is located within the second slide groove 14. The limiting member 411 allows one end of the slide rod 41 to slide within the second slide groove 14, ensuring that the control button 4 will not detach from the fixed seat, thus helping to ensure the stability and reliability of the control button 4. The bottom of the first slide groove 13 is provided with a third clearance opening 131, through which one end of the slide rod 41 passes. This allows the other end of the slide rod 41 to slide along the first slide groove 13 while one end slides along the second slide groove 14, thereby increasing the stability of the slide rod 41. Furthermore, the second elastic member 5 is located between the other end of the slide rod 41 and the bottom of the first slide groove 13, so that after the pressing seat 42 is released, the second elastic member 5 can drive the control button 4 to automatically reset.
[0051] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
