Description

Technical Field

[0001] This utility model relates to the field of display connection technology, specifically to a joint anti-foolproof structure and a display bracket. Background Technology

[0002] In the mass production of monitor bracket assemblies, to meet market demands for uniform product appearance, different monitor models typically use identical external designs for their neck structures. However, this homogenized design makes it impossible to visually distinguish between neck connectors of different specifications. During production, manual verification of models or labeling is relied upon, which easily leads to model mismatches. When assembly workers mistakenly connect heavy-duty neck components to lightweight screens, the excessive load on the joint causes abnormal rotational noises. Conversely, matching low-duty neck connectors to heavy screens results in premature wear or even breakage of the hinge, and the resulting large gaps affect the overall aesthetics, leading to a high rework rate. More seriously, the disassembly process after incorrect installation easily damages the locking mechanism at the bottom of the rotating joint and the insertion slot of the column base, causing cracks in the outer wall of the column base and increasing rework costs. Furthermore, traditional manual error-proofing methods are difficult to adapt to the requirements of automated production lines. Therefore, a foolproof design with a physical structure is needed to allow for the matching of different models of neck connectors with screens, and the structure should be simple enough to be expanded and differentiated according to the number of models. Utility Model Content

[0003] One of the purposes of this invention is to provide a joint anti-misfit structure that solves the problems of easy mismatch in existing joint structures and difficulty in distinguishing different models by visual inspection.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A joint anti-misalignment structure includes a joint seat, an anti-misalignment component, and a column seat. The anti-misalignment component is disposed on the joint seat, and the column seat is inserted into the anti-misalignment component. The anti-misalignment component includes a cavity and at least one retaining strip. The cavity is disposed in the anti-misalignment component and has an opening at one end penetrating through the anti-misalignment component. The at least one retaining strip is disposed on the side wall of the anti-misalignment component along the connection direction of the anti-misalignment component. The column seat includes a mating groove and at least one retaining slot. The mating groove is disposed on the column seat and is inserted into the anti-misalignment component. The at least one retaining slot is disposed on the inner wall of the mating groove along the insertion direction of the column seat. The retaining strip falls into the retaining slot. By differentiating the position, spacing, and length of the retaining strip, screen joint structures of different models with the same appearance can be made. The structure can be expanded according to the number of models, ensuring stable and reliable connection and physical anti-misalignment, thus eliminating the risk of mixed assembly.

[0006] Furthermore, the foolproof component includes multiple locking strips, which are disposed on the side wall of the foolproof component along the connection direction of the foolproof component. The column base includes multiple slots, which are disposed on the inner wall of the mating groove along the insertion direction of the column base. The locking strips and the slots are slidably engaged in a one-to-one correspondence. By changing the position, spacing, and length of the multiple locking strips on the inner wall of the foolproof component, the column base can be matched to achieve connection of different screen models. By combining the number of locking strips, the number of distinguishable models can be further expanded.

[0007] Furthermore, the at least one clip has a partition groove in the middle, which divides the at least one clip into two collinear segments. This ensures that some clips can play a guiding and positioning role when misassembly occurs, thereby improving the fault tolerance rate during assembly.

[0008] Furthermore, a slot is provided at one end of the column base, and a locking platform is provided on the bottom side wall of the joint base. The locking platform falls into the slot, and the column base and the joint base form a locking connection, which improves the stability of the connection and prevents shaking.

[0009] Furthermore, the anti-mistake component also includes an elastic fastener, which is disposed on the other side wall of the anti-mistake component and can deform and extend outward. The side wall of the column base is provided with a slot, and the elastic fastener falls into the slot when it is in the extended state to form a snap-fit ​​connection. It is easy to disassemble and assemble, and has a feel and a sound when it is inserted, which can be used to detect whether the insertion is in place.

[0010] Preferably, a spring is also included. The elastic fastener extends outward along one side wall of the anti-fooling component and then extends in a direction parallel to one side wall of the anti-fooling component to form a locking portion. One end of the spring abuts against one side wall of the anti-fooling component, and the other end abuts against the locking portion, thereby increasing the rebound force of the elastic fastener and ensuring stability during long-term use.

[0011] Preferably, the column base is provided with a through hole and a guide strip. The through hole is located at the other end of the column base, and the guide strip is arranged along the axial direction of the through hole on the inner side wall of the through hole for connecting the column.

[0012] Preferably, the top of the anti-misalignment component is provided with a countersunk hole, and the anti-misalignment component is fixedly connected to the joint seat by a fastener passing through the countersunk hole, so as to fix the anti-misalignment component and the joint seat as one unit.

[0013] As a preferred embodiment, the joint seat includes a turntable, a rotating shaft, a first bracket, and a second bracket. The rotating shaft is fixedly connected to the turntable, and both ends of the rotating shaft extend outwards. The first bracket and the second bracket are rotatably connected to the two ends of the rotating shaft, respectively, for supporting the screen.

[0014] The second objective of this utility model is to provide a monitor bracket that solves the problem of easy confusion when assembling the neck of the same model of screen, resulting in a high return rate.

[0015] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0016] A monitor stand, including the joint anti-misfit structure described above, can be used for installing screens of different sizes but with the same appearance. The physical structure prevents misfitting, has a good anti-misfit effect, and high assembly efficiency.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) The anti-mistaken component sidewall clips on the joint anti-mistaken structure are configured differently. Different screen models are distinguished by the position, spacing and length of the clips. The clips and slots are slidably connected to form a structural lock, so that screen brackets with the same appearance can be inserted smoothly without interference only when the models are completely matched. Incorrect models cannot be inserted due to the misalignment of the clips and slots, eliminating the risk of mixed assembly caused by human identification errors, and preventing joint noise and shaft breakage caused by mismatch of load-bearing components. By changing the position, spacing and length of the clips and slots, a variety of models can be distinguished and the expansion is strong, which is suitable for anti-mistaken use of different types of screen joint parts.

[0019] (2) The sliding fit of the locking strip and the slot of the joint anti-foolproof structure is combined with the self-locking mechanism of the elastic fastener automatically locking into the slot in the relaxed state. During the assembly process, blind insertion can be performed without inspection, which significantly improves the efficiency of automated production. Moreover, the transformation of different types of joint structures only requires adjusting the layout of the anti-foolproof ribs or the distribution of the screen seat slots. The cost of mold production is low, which reduces the overall manufacturing cost. Attached Figure Description

[0028] 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 in the application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Example 1

[0030] like Figures 1-6 As shown, this embodiment discloses a joint anti-mistake structure, including a joint seat 3, an anti-mistake component 2, and a column seat 1. The anti-mistake component 2 is disposed on the joint seat 3, and the column seat 1 is inserted into the anti-mistake component 2. The anti-mistake component 2 includes a cavity 22 and at least one retaining strip 21. The cavity 22 is disposed in the anti-mistake component 2, and the cavity 22 penetrates one end of the anti-mistake component 2 to form an opening. The joint seat 3 is inserted into the anti-mistake component 2 through the opening of the cavity 22. The assembly action is simple and the connection is stable. At least one retaining strip 21 is disposed on the side wall of the anti-mistake component 2 along the connection direction of the anti-mistake component 2, that is, the retaining strip 21 is in the same insertion direction as the anti-mistake component 2. The retaining strip 21 plays a guiding and positioning role during insertion. The column seat 1 includes a docking groove 11 and at least one retaining groove 12. The docking groove 11 is disposed on the column seat 1. On the base 1, the docking groove 11 is inserted into the anti-foolproof component 2 for positioning. At least one slot 12 is set on the inner wall of the docking groove 11 along the insertion direction of the column base 1. The locking strip 21 falls into the slot 12 to form a sliding fit. Through the structural matching of the locking strip 21 and the slot 12, the joint base 3 and the column base 1 can be aligned during assembly. If the locking strip 21 and the slot 12 do not align, they cannot be inserted, fundamentally eliminating the mismatch between the joint base 3 and the column base 1, preventing joint noise and shaft breakage caused by load mismatch, and reducing the rework rate. In addition, the number of screen models that can be distinguished can be increased by expanding the mating position and length of the locking strip 21 and the slot 12. It has strong expandability and is mainly used for anti-foolproofing of the neck of the monitor bracket.

[0031] Furthermore, at least one card strip 21 has a partition groove 23 in the middle, which divides at least one card strip 21 into two collinear segments. After the card strip 21 is separated, it can still be accurately guided, and it can also prevent the structure from being completely damaged and unable to install the screen after incorrect insertion, thus improving the fault tolerance rate of the insertion.

[0032] Furthermore, a slot 13 is provided on one end of the column base 1, and a locking platform 32 is provided on the bottom side wall of the joint base 3. The locking platform 32 falls into the slot 13. Multiple slots 13 can be provided on the end face of the column base 1. Multiple slots 13 are distributed around the center of the docking groove 11, which effectively prevents the column base 1 and the joint base 3 from shaking relative to each other after they are inserted, and improves the stability of the supporting screen.

[0033] Furthermore, the foolproof component 2 also includes an elastic fastener 24, which is located on the other side wall of the foolproof component 2 and can deform and extend outward. The side wall of the column base 1 is provided with a latch 16. When the elastic fastener 24 is in the extended state, it falls into the latch 16 to form a latch connection. Pressing the elastic fastener 24 so that it moves toward the side wall of the column base 1 can unlock the latch between the column base 1 and the foolproof component 2. During use, the screen and the column can be quickly disassembled and assembled. The elastic fastener 24 has a certain feel and sound when it is pressed into the latch 16, which can be used to judge the completion of the insertion without visual inspection, thus improving the assembly efficiency.

[0034] Preferably, it also includes a spring 6. The elastic fastener 24 extends outward along one side wall of the anti-foolproof member 2 and then extends in a direction parallel to one side wall of the anti-foolproof member 2 to form a locking part. One end of the spring 6 abuts against one side wall of the anti-foolproof member 2, and the other end abuts against the locking part, which is used to support the elastic fastener 24, increase the magnitude of the rebound force, and ensure that the elastic fastener 24 can still rebound stably to form a locking part after a long time.

[0035] More preferably, the column base 1 is provided with a through hole 14 and a guide strip 15. The through hole 14 is provided at the other end of the column base 1, and the guide strip 15 is provided on the inner side wall of the through hole 14 along the axial direction of the through hole 14. The through hole 14 is used to connect the column, and the guide strip 15 contacts the surface of the column, reducing the friction when inserting the column, and allowing for the manufacturing tolerance of the column, making assembly easier.

[0036] More preferably, the top of the anti-mistake component 2 is provided with a recessed hole, and the anti-mistake component 2 is fixedly connected to the joint seat 3 by fasteners passing through the recessed hole. The anti-mistake component 2 and the joint seat 3 are connected as one unit. After the column seat 1 is connected to the screen, it is inserted into the column, and the structure is reasonably distributed.

[0037] More preferably, the joint seat 3 includes a turntable 4, a rotating shaft 41, a first bracket 51 and a second bracket 54. The rotating shaft 41 is fixedly connected to the turntable 4, and both ends of the rotating shaft 41 extend outwards. The first bracket 51 and the second bracket 54 are respectively rotatably connected to the two ends of the rotating shaft 41. The first bracket 51 and the second bracket 54 are connected to the screen to expand the area supporting the screen and improve the load-bearing capacity and support stability.

[0038] More preferably, the joint seat 3 also includes a plug-in platform 31, which is fixedly connected to one end face of the turntable 4. The side wall of the connection end face of the plug-in platform 31 and the turntable 4 protrudes outward to form a locking platform 32. The locking platform 32 cooperates with the slot 13 and the guide block on the side wall of the plug-in platform 31 contacts the inner wall of the cavity 22 to guide and position the column seat 1 into the anti-foolproof component 2, and the insertion is smooth.

[0039] More preferably, a first torsion spring 52 and a second torsion spring 55 are respectively sleeved on the rotating shaft 41, and the two are respectively connected to the first bracket 51 and the second bracket 54 to provide the torsional force for screen pitch. A first slack nut 53 and a second slack nut 56 are connected to both ends of the rotating shaft 41 to adjust the damping of the bearing 5.

[0040] The assembly process of this joint anti-fouling structure is as follows:

[0041] Select the appropriate anti-misalignment component 2 according to the different screen models. Align the opening of the cavity 22 of the anti-misalignment component 2 with the insertion platform 31 of the joint seat 3 and insert it. Use fasteners to pass through the countersunk hole at the top of the anti-misalignment component 2 to fix the anti-misalignment component 2 to the joint seat 3. Install the spring 6 between the elastic fastener 24 and the side wall of the anti-misalignment component 2 and press to check. Take the corresponding column seat 1 of the anti-misalignment component 2, so that the docking groove 11 is opposite to the anti-misalignment component 2. After being guided by the slot 12 and the clip 21, insert it to the bottom. After being inserted to the bottom, the end face slot 13 of the column seat 1 and the insertion platform 31 form a fit. At this time, the elastic fastener 24 falls into the slot 16 to form a snap connection, that is, the assembly is in place.

[0042] Example 2

[0043] See Figure 6This embodiment also discloses a joint anti-mistake structure. The anti-mistake component 2 includes multiple locking strips 21, which are disposed on the side wall of the anti-mistake component 2 along the connection direction of the anti-mistake component 2. The column base 1 includes multiple locking slots 12, which are disposed on the inner wall of the docking groove 11 along the insertion direction of the column base 1. The locking strips 21 and the locking slots 12 are slidably engaged in a one-to-one correspondence. By changing the position, spacing and length of the multiple locking strips 21 on the inner wall of the anti-mistake component 2, the column base 1 can be matched to achieve connection of different types of screens. The number, position and length of the locking strips 21 and the locking slots 12 can be arranged and combined according to the different number of screen models of the same type, so that the screen neck structure can be distinguished. Furthermore, by changing the cross-section of the insertion cavity 22 of the anti-mistake component 2, the joint anti-mistake structure can be extended to the assembly and use of other types of screens, thereby reducing manufacturing costs.

[0044] Specifically, the anti-foolproof component 2 has two locking strips 21 on its side wall, and the two locking strips 21 have different lengths. The inner wall of the column base 1 is provided with two corresponding slots 12, and the depth of the two slots 12 corresponds one-to-one with the two locking strips 21. More specifically, the two locking strips 21 and the two slots 12 are set to be either left longer than right or left shorter than right, which can be used to distinguish between two types of screen neck structure components.

[0045] Example 3

[0046] This embodiment also discloses a display bracket, including a joint anti-foolproof structure, a screen and a column. The screen is connected and supported by a first bracket 51 and a second bracket 54 on the carrier 5. The screen can rotate around the pivot 41. The column is inserted into the through hole 14. The outer wall of the column contacts the guide strip 15 to provide support.

[0047] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and any modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
