Description

Technical Field

[0001] This utility model relates to the field of display screen assembly structure technology, specifically a non-loosening snap-fit ​​display screen splicing frame. Background Technology

[0002] Display screen frames are supporting components that adapt to the structure of display screens. They are usually made of plastic and are wrapped around or embedded around the display screen. They mainly serve to fix the screen module, protect internal components, and assist in assembly and positioning. At the same time, they can optimize the structural stability and edge protection performance of the display screen and adapt to the installation needs of display screens of different sizes and types.

[0003] Publication number CN221650768U discloses an anti-loosening splicing display frame. It involves merging a first and second frame, inserting a toothed plate into the inner side of the splicing groove, and then installing a locking block at the groove opening. The locking blocks' feet embed into the locking groove formed by the junction of the toothed plate and the splicing groove, simultaneously engaging the protruding teeth with the toothed plate. A countersunk screw passes through the countersunk hole and is screwed into the screw hole to secure the locking block, thus ensuring a tight fit between the first and second frames and guaranteeing the stability of the splicing between them, effectively preventing loosening. However, this patent still has the following problems in practical use: In existing technologies, splicing display screen frames mostly adopt a two-section structure design, which is assembled by interlocking toothed plates with splicing slots and fixing them with screws. However, this has many drawbacks in practical applications: during assembly, it is necessary to manually align the interlocking parts of the toothed plates and splicing slots precisely, and the interlocking and screwing operations must be completed sequentially, which is cumbersome and leads to low installation efficiency; during long-term use, the screws are prone to loosening due to vibration, and the interlocking parts lack elastic compensation structures, which can easily create gaps and affect the stability of the splicing frame; at the same time, the two-section splicing structure lacks a flexible corner connection design, making it difficult to adapt to the assembly requirements of display panels of different sizes, and disassembly and assembly require the removal of fasteners one by one, which is inconvenient and has high maintenance costs.

[0004] Therefore, a non-loosening snap-fit ​​display splicing frame is proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-loosening snap-fit ​​display splicing frame to solve the problems of cumbersome installation, poor stability and low adaptability of the current two-section structure of splicing display frames mentioned in the background art, which leads to low efficiency and high maintenance costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-loosening snap-fit ​​display splicing frame, comprising a display panel and a frame assembly disposed around the periphery of the display panel. The frame assembly includes corner connecting frames disposed at the four top corners of the display panel, and a long frame body and a short frame body connected between two adjacent corner connecting frames; The corner connecting frame is equipped with a quick-positioning latch and a self-locking anti-loosening component at the connection end with the long or short frame body. The quick positioning latch includes a guide pin, which is used to achieve alignment and initial engagement between the corner connecting frame and the long or short frame body. The self-locking anti-loosening component includes a locking post slidably disposed inside the corner connecting frame, and a driving member for moving the locking post; the locking post is used to engage with an elastic locking pin disposed on the long or short side frame when in the locked position to prevent the side frame from loosening from the corner connecting frame.

[0007] Preferably, the outer sides of both ends of the guide pin are respectively engaged with the corner connecting frame and the long or short frame body, and the inner sides of both ends of the guide pin are fixedly connected with elastic retaining rings for providing radial preload.

[0008] Preferably, the driving component is a knob driving mechanism, which includes an unlocking slide rod slidably connected to the locking post, and an unlocking knob for driving the unlocking slide rod to move axially; the unlocking knob is threadedly connected to the corner connecting frame.

[0009] Preferably, the locking post has a sliding rod guide groove inside, and the unlocking sliding rod is slidably connected to the inside of the sliding rod guide groove; a connecting rod is fixedly connected to the top center of the unlocking sliding rod, and the top end of the connecting rod is rotatably connected to the unlocking knob; both the unlocking sliding rod and the connecting rod are slidably connected to the corner connecting frame.

[0010] Preferably, a return spring is fixedly connected to one end of the locking post, and the other end of the return spring abuts against the internal cavity of the corner connecting frame to provide a return force to the locking post toward the locking position.

[0011] Preferably, the elastic locking pin includes a pin seat fixedly connected to the long frame or the short frame, and an expansion clamp fixedly connected to one end of the pin seat. The expansion clamp extends into the corner connecting frame and can be clamped by the locking post in the locking position to achieve locking.

[0012] Preferably, the internal structures at both ends of the corner connecting frame are arranged symmetrically along the diagonal.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This anti-loosening snap-fit ​​display splicing frame, through quick-positioning latches, self-locking anti-loosening components and modular design, achieves precise positioning, stable anti-loosening and convenient assembly and disassembly of the splicing frame, improving assembly efficiency and structural adaptability. The specific details are as follows: Firstly, this utility model sets a quick-positioning latch at the connection end of the corner connecting frame and the long / short frame body. Its guide pin can directly realize the precise alignment and initial engagement of the two without the need for manual repeated calibration of the position of the toothed plate and the splicing groove. At the same time, the elastic retaining rings on the inner side of both ends of the guide pin can provide radial pre-tightening force, so that a stable fit can be formed in the initial engagement stage, eliminating the need for separate pre-fixing operation, simplifying the assembly process and shortening the assembly time.

[0014] Secondly, this utility model enhances the connection stability of the frame splicing through its anti-loosening structure design, overcoming the defects of existing technologies such as easy loosening of screws and easy gaps in the locking parts. In the self-locking anti-loosening component, the locking pin can be tightly engaged with the elastic locking pin on the long / short frame body under the action of the driving component, preventing the frame body and the corner connecting frame from loosening due to vibration; the return spring can continuously provide the locking pin with a return force towards the locking position, ensuring a stable and reliable locking state; and the cooperation between the expansion clamp of the elastic locking pin and the locking pin, as well as the pre-tightening effect of the elastic retaining ring, can elastically compensate for the assembly gap, further improving the tightness of the connection and ensuring the structural stability of the frame for long-term use.

[0015] Finally, this utility model possesses excellent adaptability and ease of maintenance, solving the problems of poor adaptability and inconvenient assembly and disassembly in existing two-section splicing structures. The frame assembly adopts a modular design combining corner connecting frames and long / short frame bodies. With the symmetrical internal structure along the diagonal at both ends of the corner connecting frames, it can flexibly adapt to the assembly requirements of display panels of different sizes without the need to redesign the overall structure for specific sizes. At the same time, the self-locking anti-loosening component adopts a knob-driven mechanism. The movement and unlocking of the locking pin can be achieved by rotating the unlocking knob, without the need to disassemble the fasteners one by one, reducing the difficulty of disassembly and assembly and maintenance costs.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] like Figure 1-8 As shown, the anti-loosening snap-fit ​​display splicing frame provided by this utility model mainly consists of a display panel 1 and a frame assembly. The frame assembly is a splicing structure, specifically including four corner connecting frames 2, two long frame bodies 5, and two short frame bodies 6. The four corner connecting frames 2 are respectively installed at the four top corners of the display panel 1. The long frame bodies 5 connect between two opposite corner connecting frames 2 and are adapted to the length of the long side of the display panel 1. The short frame bodies 6 connect between the other two opposite corner connecting frames 2 and are adapted to the length of the short side of the display panel 1. Through the splicing of the corner connecting frames 2 and the long and short frame bodies, a frame structure for fixing the display panel 1 is formed.

[0020] The corner connecting frame 2, the long frame body 5, and the short frame body 6 are all made of high-strength engineering plastic through one-piece injection molding, which has the characteristics of being lightweight, corrosion-resistant, and structurally stable. Their inner sidewalls are provided with limiting grooves that fit the edge of the display panel 1, and the edge of the display panel 1 is embedded in the limiting groove to achieve axial positioning.

[0021] The quick positioning latch 3 is set at the connection end of the corner connecting frame 2 and the long side frame 5 and the short side frame 6. Its core function is to realize quick alignment and initial locking during splicing. It is mainly composed of guide pin 301 and elastic retaining ring 302.

[0022] The guide pin 301 has a double-arrow-shaped structure, with its axis perpendicular to the splicing surface of the corner connecting frame 2 and the frame body. The connecting end of the corner connecting frame 2 has a first slot that matches one end of the guide pin 301, and the ends of the long frame body 5 and the short frame body 6 have corresponding second slots that match the other end of the guide pin 301. The inner walls of the first slot and the second slot have corresponding locking protrusions. After the two ends of the guide pin 301 are inserted into the first slot and the second slot respectively, the locking protrusions are embedded in the annular locking groove to achieve axial engagement and complete the initial fixation.

[0023] The elastic retaining ring 302 is a ring-shaped rubber part, which is fixedly sleeved on the inner side of both ends of the guide pin 301. When the guide pin 301 is inserted into the slot, the elastic retaining ring 302 is in a compressed state, applying radial preload to the inner wall of the slot, eliminating the gap between the guide pin and the slot, and avoiding slight shaking after splicing.

[0024] The self-locking anti-loosening component 4 is arranged adjacent to the quick positioning lock 3 to lock and fix the corner connecting frame 2 and the frame body, preventing loosening during long-term use or under vibration. It mainly consists of a locking post 401, a driving component, a return spring 406 and an elastic locking pin 407.

[0025] Locking post 401: A cylindrical structure, slidably mounted within a guide cavity inside the corner connecting frame 2, with the guide cavity extending perpendicular to the splicing surface. An inclined slide guide groove 402 is provided inside the locking post 401 along its length. Drive mechanism: A knob-driven mechanism is adopted, including an unlocking slide 403, a connecting rod 404, and an unlocking knob 405. The unlocking slide 403 slides through the slide guide groove 402, and its top center is vertically fixed to the connecting rod 404. The top of the corner connecting frame 2 has a guide hole adapted to the connecting rod 404. After the top of the connecting rod 404 passes through the guide hole, it is rotatably connected to the unlocking knob 405 through a bearing. The inner side of the unlocking knob 405 has an internal thread, and the top of the corner connecting frame 2 has a corresponding external thread. The unlocking knob 405 is threadedly connected to the corner connecting frame 2.

[0026] Return spring 406: It is a compression spring. One end of it is fixedly connected to the end of the locking pin 401 away from the elastic locking pin 407, and the other end abuts against the inner wall of the end of the guide cavity. Under normal conditions, the return spring 406 is in a compressed state, applying a return force toward the elastic locking pin 407 to the locking pin 401, so that the locking pin 401 is kept in the locked position.

[0027] Elastic locking pin 407: Fixedly installed on the end side of the long frame body 5 and the short frame body 6, including pin seat 4071 and expansion clamp 4072. Pin seat 4071 is a cylindrical metal part, which is fixed in the mounting hole at the end of the frame body by screws; expansion clamp 4072 is an elastic metal clamp, one end of which is fixedly connected to pin seat 4071, and the other end is a free end and is in an expanding shape. When the frame body is spliced ​​with the corner connecting frame 2, the expansion clamp 4072 extends into the corresponding through hole opened inside the corner connecting frame 2. Locking pin 401 moves to the locking position under the action of return spring 406. Locking pin 401 is sleeved on the inside of expansion clamp 4072 and squeezes it to expand, so that expansion clamp 4072 fits tightly with the inner wall of the through hole, preventing locking pin 401 from retracting.

[0028] The internal structures at both ends of the corner connecting frame 2 are symmetrically arranged along their diagonal lines. That is, the installation positions and structures of the quick-positioning latches 3 and the self-locking anti-loosening components 4 in the two connecting ends of the corner connecting frame 2 (which connect to the long side frame and the short side frame respectively) are completely symmetrical. This design makes the structures of the four corner connecting frames 2 completely identical, eliminating the need to distinguish between long-side dedicated and short-side dedicated frames, reducing the cost of production molds and the difficulty of identification during assembly, and improving assembly efficiency.

[0029] Working principle: Before using this type of anti-loosening snap-fit ​​display splicing frame, it is necessary to check the overall condition of the device to ensure it can work normally. Figure 1 - Figure 8 As shown, during assembly, the four corner connecting frames 2 are first placed to correspond to the four top corners of the display panel 1. Then, the long frame body 5 and the short frame body 6 are aligned with the connecting ends of two adjacent corner connecting frames 2 and mated. At this time, the guide pin 301 in the quick positioning latch 3 plays a core positioning role. Its two outer ends are precisely engaged with the corresponding slots of the corner connecting frames 2 and the mating slots of the long frame body 5 or the short frame body 6, directly completing the axial alignment of each frame component and avoiding splicing misalignment. At the same time, the elastic retaining rings 302 fixedly connected to the inner ends of the guide pin 301 undergo radial deformation, applying a continuous radial preload to the mating surface, so that the corner connecting frame 2 and the frame body are initially fixed, laying the foundation for the subsequent locking process.

[0030] After the initial engagement is completed, the self-locking anti-loosening component 4 automatically enters the locking state. The locking pin 401 is slidably disposed in the internal cavity of the corner connecting frame 2, and the return spring 406 at one end is always in a pre-compressed state, applying a return force towards the locking position to the locking pin 401. When the long frame body 5 or the short frame body 6 is aligned with the corner connecting frame 2, the elastic locking pin 407 fixed on the frame body extends into the corner connecting frame 2 during the alignment action. Its pin seat 4071 is rigidly connected to the frame body to ensure installation stability, while the extended expansion clamp 4072 is exactly within the locking stroke range of the locking pin 401. Under the driving force of the return spring 406, the locking pin 401 slides towards the elastic locking pin 407, and finally clamps the expansion clamp 4072. Through mechanical engagement, the axial displacement of the elastic locking pin 407 is limited, thereby completely preventing the long frame body 5, the short frame body 6 and the corner connecting frame 2 from loosening, achieving long-term anti-loosening.

[0031] When it is necessary to disassemble the plastic frame, rotate the unlocking knob 405. The threaded transmission converts the rotational motion into the axial movement of the unlocking slide bar 403. The unlocking slide bar 403 drives the locking pin 401 to overcome the elastic force of the return spring 406 and slide away from the elastic locking pin 407, so that the locking pin 401 and the expansion clamp 4072 are disengaged. At this time, the corner connecting frame 2 can be easily separated from the long frame body 5 or the short frame body 6, and the disassembly is completed.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
