Description

Technical Field

[0001] This utility model relates to the field of flexible screen technology, and in particular to a flexible screen stretch lock. Background Technology

[0002] With the development of display technology, there is a demand for curved or arc-shaped screens, where multiple display unit cabinets are connected at a certain angle to form an arc, or flexible screens are bent into an arc, resulting in an overall curved display screen. In existing technologies, tension locks or adjustment mechanisms are typically installed on the display unit cabinets to achieve angle adjustment and provide a locking function.

[0003] In a specific implementation of the arc-shaped adjustment mechanism, Chinese patent document CN112443566A discloses an arc-shaped adjustment mechanism, which specifically includes two first telescopic mechanisms and a limiting mechanism. The first telescopic mechanism includes a first fixed base, a first movable member, a second movable member, and a second fixed base, with the first and second movable members slidingly engaged. The limiting mechanism is located between the two first telescopic mechanisms, with its two ends connected to the second movable member. This limiting mechanism can both lock the relative position between the first and second movable members, thereby maintaining the bending angle of the flexible screen, and also serves as an adjustment handle between the two first telescopic mechanisms.

[0004] However, this technical solution has significant shortcomings in practical applications: because the limiting mechanism simultaneously serves as both a locking function and an adjusting handle, it is prone to loosening after prolonged and frequent use. This loosening not only affects the accuracy and feel of operation but also leads to a loosening of the entire arc-shaped adjusting mechanism's structure, reducing its reliability in maintaining the preset angle.

[0005] Therefore, how to overcome the problems of loose structure and insufficient reliability of existing arc-shaped adjustment mechanisms has become an urgent technical problem to be solved in this field. Utility Model Content

[0014] Optionally, the tensioning handle includes two locking sleeves and a handle, with the two locking sleeves arranged side by side and the two ends of the handle respectively connected to the first ends of the two locking sleeves; The number of the locking rod assemblies is two sets, and the two locking rod assemblies are respectively set one-to-one with the two locking sleeves; The two ends of the locking mechanism extend into the sliding grooves of the two locking sleeves respectively, and the two ends of the locking mechanism are respectively engaged with the two telescopic rods for locking or releasing the telescopic rods.

[0023] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0024] Large LED screens are composed of multiple smaller screen units connected together. The angle of adjacent LED screens or the overall curvature of the LED screen can be adjusted by changing the angle of adjacent screen units. This requires the use of tools such as... Figure 1 The flexible screen stretch lock shown stretches adjacent screen units from the back of the LED screen. Of course, the flexible screen stretch lock can also serve as a frame stretching structure for the entire flexible screen, with multiple screen units between the flexible screen stretch locks acting as a fixed and adjustable structure for the frame.

[0025] like Figure 2-4 The flexible screen tension lock shown includes a tensioning assembly and a locking rod assembly. The tensioning assembly includes a tension handle 1, a locking mechanism 2, and a first hinge seat 3. The tension handle 1 includes a locking sleeve 11 and a handle 12 disposed at the first end of the locking sleeve 11. The first end of the locking sleeve 11 has a groove 111 extending to the second end. The second end of the locking sleeve 11 is connected to the first hinge seat 3. The locking mechanism 2 is disposed within the handle 12. The locking rod assembly includes a telescopic rod 4 and a second hinge seat 5. The first end of the telescopic rod 4 is connected to the second hinge seat 5, and the second end of the telescopic rod 4 extends into the groove 111 and slides in cooperation with the locking sleeve 11. The locking mechanism 2 partially extends into the groove 111 and engages with the telescopic rod 4, used to lock or release the telescopic rod 4.

[0026] In this invention, by lifting and pressing the tension handle 1, specifically the handle 12, the telescopic rod 4 can slide freely. The locking mechanism 2 controls the sliding and locking of the telescopic rod 4 within the sliding groove 111 of the locking sleeve 11. When the locking mechanism 2 is released, lifting and pressing the tension handle 1 allows the telescopic rod 4 to slide freely, enabling length adjustment of the flexible screen tension lock, thereby adjusting the curvature or angle of the flexible screen. When the locking mechanism 2 is locked, the telescopic rod 4 is fixed, maintaining the set tension length and locking the curvature or angle adjustment of the flexible screen. The first hinge seat 3 and the second hinge seat 5 are used to connect different screen units, and the bending angle of the display screen is controlled by adjusting the length of the tension lock. In this utility model, the flexible screen tension lock is configured with two main structures: a tensioning component and a locking rod component. The handle 12 and the locking sleeve 11 are integrated onto the tension handle 1 as a whole structure. The locking mechanism 2 is integrated into the tension handle 1, and the handle 12 is no longer part of the locking mechanism 2. This avoids the independent assembly of the handle 12 and the locking mechanism 2, reduces the problem of loosening of the handle 12 and the locking mechanism 2, improves the stability of the assembly, reduces outdoor maintenance and adjustment, and avoids the problems of loose structure and insufficient reliability in the prior art.

[0027] In some embodiments of the locking mechanism 2, such as Figure 3 , Figure 4 As shown, the locking mechanism 2 includes a locking rod 21, an elastic element 22, and an unlocking rod 23. The locking rod 21 is slidably disposed in the handle 12, and the first end of the locking rod 21 extends into the slide groove 111 and abuts against the telescopic rod 4 to lock it. The elastic element 22 is disposed in the handle 12 and abuts against the locking rod 21 to push the locking rod 21 to maintain the locked state. The outer end of the unlocking rod 23 extends out of the handle 12, and the inner end of the unlocking rod 23 abuts against the locking rod 21 to push the locking rod 21 to unlock the telescopic rod 4.

[0028] In this embodiment, the elastic force of the elastic element 22 continuously pushes the locking rod 21 to press the telescopic rod 4, achieving a normally closed locking mechanism. When unlocking, pressing the unlocking rod 23 overcomes the elastic force, causing the locking rod 21 to retract and releasing the locking state. This embodiment ensures that the mechanism remains locked in the absence of external force, greatly improving safety and reliability. The elastic element 22 not only provides locking force but also acts as a buffer, making the locking process smoother.

[0029] The handle 12 has a through hole through which the unlocking lever 23 can pass. The unlocking lever 23 can be rod-shaped or plate-shaped.

[0030] Furthermore, such as Figure 4As shown, the telescopic rod 4 has several positioning grooves 41 extending along its length on its side; the first end of the locking rod 21 has a positioning protrusion 211. When the first end of the locking rod 21 abuts against the telescopic rod 4 and is locked, the positioning protrusion 211 is embedded in the positioning groove 41.

[0031] The locking rod 21 achieves precise locking through the mechanical engagement of the first positioning member 211 and the positioning groove 41. Multiple positioning grooves 41 provide multiple preset locking positions, making adjustment more precise and reliable. When the locking rod 21 is inserted into the positioning groove 41 under the guidance of the positioning protrusion 211, a reliable mechanical interlock is formed, effectively preventing accidental slippage of the telescopic rod 4 under stress, making it particularly suitable for display installation scenarios that need to withstand certain loads.

[0032] Regarding unlock lever 23, specifically, as follows: Figure 3 As shown, the middle part of the unlocking lever 23 is pivotally connected to the handle 12. The first end of the unlocking lever 23 extends into the handle 12. The first end of the unlocking lever 23 abuts against the locking lever 21, pushing the unlocking lever 23 to move in the unlocking direction of the locking lever 21. The second end of the unlocking lever 23 extends out of the handle 12.

[0033] The unlocking lever 23 uses the lever principle to transmit force. Through the pivot point, the small operating force applied by the user to the second end of the unlocking lever 23 is converted into a larger force to move the locking lever 21, thus achieving effortless operation. This design significantly reduces the force required for unlocking, making the adjustment process easier and more convenient, and is particularly suitable for applications that require frequent adjustments.

[0034] In some further embodiments of the locking mechanism 2, such as Figure 3 , Figure 4 and Figure 5 As shown, the locking mechanism 2 also includes a locking slider 24, which includes a sliding part 241, a push part 242, and a locking part 243. The sliding part 241 is slidably disposed in the handle 12. The push part 242 is connected to the side of the sliding part 241 and protrudes from the handle 12. The locking part 243 is disposed on the sliding part 241 and extends to the unlocking rod 23 to lock the unlocking rod 23 and prevent it from swinging.

[0035] This invention adds a secondary locking function to the basic locking mechanism 2. The locking slider 24, through the linear motion of the sliding part 241, drives the locking part 243 to lock or release the unlocking rod 23. When the locking part 243 is in the locked position, it can effectively prevent accidental unlocking due to accidental contact or vibration, providing additional safety. This double safety mechanism is particularly suitable for applications in vibration environments or applications with high safety requirements.

[0036] Furthermore, such as Figure 6As shown, the unlocking lever 23 has at least two locking grooves 231 arranged along its length on its side; the locking part 243 has a pointed tip that can be inserted into the locking groove 231 to prevent the unlocking lever 23 from swinging downwards. Through the cooperation of the pointed tip and the locking groove 231, precise control of the swing angle of the unlocking lever 23 is achieved. Multiple locking grooves 231 correspond to different locking states, such as fully locked and ready-to-unlock states. The pointed tip, after being inserted into the groove, forms a mechanical interlock, providing a reliable locking effect. This design ensures the stability of the locking state while providing clear operational feedback to the user.

[0037] The sliding part 241 is arranged along the width direction of the handle 12. The middle of the sliding part 241 is also provided with a clearance groove 2411 for avoiding the locking rod 21. The sliding part 241 is provided with a guide groove 2412, and the handle 12 is also provided with a guide rail that matches the guide groove 2412. The precise fit between the guide groove 2412 and the guide rail ensures that the locking slider 24 slides smoothly along a predetermined trajectory, preventing skewing and jamming. The design of the clearance groove 2411 avoids motion interference between the locking slider 24 and the locking rod 21, allowing all components to work in coordination. This precise guiding mechanism improves the overall service life and operating feel of the product.

[0038] In some embodiments of the tension handle 1, as described above, the tension handle 1 includes a locking sleeve 11 and a handle 12. Of course, in some preferred embodiments, such as... Figure 2 As shown, the tension handle 1 includes two locking sleeves 11 and a handle 12. Specifically, the two locking sleeves 11 are arranged side by side, and the two ends of the handle 12 are respectively connected to the first ends of the two locking sleeves 11; there are two sets of locking rod assemblies, and the two locking rod assemblies are respectively arranged in a one-to-one correspondence with the two locking sleeves 11; the two ends of the locking mechanism 2 extend into the sliding grooves 111 of the two locking sleeves 11, and the two ends of the locking mechanism 2 are respectively engaged with the two telescopic rods 4 for locking or releasing the telescopic rods 4.

[0039] The symmetrical arrangement of two locking systems provides more balanced and stable support. A single handle 12 controls both locking mechanisms 2, enabling synchronous operation and ensuring consistent length adjustment of the telescopic rods 4 on both sides. This design is particularly suitable for the installation of large flexible screens, effectively distributing stress and improving the stability and reliability of the overall structure. Furthermore, integrating the two locking sleeves 11 and the handle 12 into a tension handle 1 reduces assembly, increases overall structural strength, and prevents loosening issues that may occur over prolonged use.

[0040] Furthermore, such as Figure 4As shown, each of the two telescopic rods 4 has several positioning grooves 41 extending along its length on its first side. The first side of each telescopic rod 4 also has a receiving groove 42 extending along its length, extending through to the second side of the telescopic rod 4 opposite to its first side. The two telescopic rods 4 are arranged side-by-side with their first sides in the same direction. The first end of the locking mechanism 2 extends from the first side of one of the telescopic rods 4 into the receiving groove 42, or the first end of the locking mechanism 2 has a positioning protrusion 211 adapted to the positioning groove 41. The second end of the locking mechanism 2 extends from the second side of the other telescopic rod 4 into the receiving groove 42, protruding from the first side of the telescopic rod 4, and also has a positioning protrusion 211 adapted to the positioning groove 41. The positioning protrusions 211 at both ends of the locking mechanism 2 are located on the first side of the two telescopic rods 4, respectively.

[0041] The double-locking scheme accommodates the movement of the locking mechanism 2 through the receiving groove 42, with the locking mechanism 2 partially passing through the receiving groove 42. The second end of the locking mechanism 2 passes through the receiving groove 42. On the locking mechanism 2, the positioning protrusion 211 is located on the first side of the corresponding telescopic rod 4. When the locking mechanism 2 is locked in a moving manner, both ends of the locking mechanism 2 can be locked and engaged with the positioning groove 41 on the first side of the corresponding telescopic rod 4 through the positioning protrusion 211, thereby achieving unidirectional locking of the two locking rod assemblies.

[0042] Specifically, such as Figure 3 As shown, the specific structure of the locking mechanism 2 is as described above. The receiving groove 42 is specifically used to receive the locking rod 21. The second end of the locking rod 21 passes through the receiving groove 42. The second end of the locking rod 21 is provided with a positioning protrusion 211. The positioning protrusions 211 at both ends of the locking rod 21 are respectively located on the first side of the corresponding telescopic rod 4. In this way, the locking rod 21 maintains the tendency to move towards the second side of the telescopic rod 4 under the drive of the elastic member 22, and continuously locks the first side of the telescopic rod 4 through the positioning protrusion 211.

[0043] Regarding the aforementioned telescopic rod 4, as Figure 4 As shown, the telescopic rod 4 is equipped with scale markings 43 arranged along its length, and the locking sleeve 11 is equipped with a display window 112 for displaying stretching data. The intuitive scale markings 43 and display window 112 provide users with a precise length reference. Users can directly read the current stretching length, thereby precisely controlling the bending angle of the display screen.

[0044] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
