Detailed implementation manners

[0034] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0035] As Figure 5 , Figure 6 and Figure 9As shown, an embodiment of the utility model provides a hanging arm assembly. The hanging arm assembly includes a hanging arm 10, on which a buckle position 11 is provided; a locking component, including a lock 21 and a pulling member 22, wherein the lock 21 is movable relative to the hanging arm 10, and the lock 21 and the buckle position 11 form a clamping space capable of clamping or releasing the wall panel 1; an operating component 30, which is located on the side of the lock 21 away from the buckle position 11; wherein the pulling member 22 is connected to the lock 21, and the lock 21 is pulled to a locking position locked with the hanging arm 10 by the pulling member 22, and the lock 21 is away from the buckle position 11; the operating component 30 is linked with the lock 21, and the lock 21 is pushed to an unlocking position separated from the hanging arm 10 by the operating component 30, and the lock 21 is close to the buckle position 11.

[0036] In the above technical solution, by pulling the pulling member 22, the lock buckle 21 is moved in the direction away from the buckle position 11, so that the lock buckle 21 and the hanging arm 10 are locked and matched, so that the lock buckle 21 can be maintained in the locked position away from the buckle position 11. In this way, the lock buckle 21 and the buckle position 11 can form a space for releasing the wall panel 1, so as to facilitate the removal of the hanging arm 10 from the wall panel 1. Compared with the need to pull the pulling member 22 all the time to remove the hanging arm 10, in the utility model, the hanging arm 10 can be removed from the wall panel 1 without pulling the pulling member 22 all the time, thereby making the operation of removing the hanging arm 10 more convenient.

[0037] Specifically, in the embodiment of the utility model, by pushing the operating component 30, the lock buckle 21 is moved in the direction close to the buckle position 11, so that the lock buckle 21 can be in the unlocked position disengaged from the hanging arm 10, so that the lock buckle 21 and the buckle position 11 form a space that can clamp the wall panel 1.

[0038] Specifically, in the embodiment of the present invention, the pulling member 22 is a pulling rope.

[0039] Specifically, in the embodiment of the present invention, the buckle position 11 is a protrusion disposed toward the lock buckle 21 .

[0040] like Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown, in an embodiment of the utility model, the operating component 30 includes a linkage member 31, which is located on a side of the lock buckle 21 away from the buckle position 11, and the linkage member 31 is movably arranged relative to the hanging arm 10 so that the linkage member 31 has a first position close to the lock buckle 21 and a second position away from the lock buckle 21; when the linkage member 31 moves to the first position, the lock buckle 21 switches from the locked position to the unlocked position, and when the linkage member 31 moves to the second position, the pulling member 22 is pulled, and the lock buckle 21 switches from the unlocked position to the locked position.

[0041] In the above technical solution, when it is necessary to lock the latch 21, the linkage member 31 moves away from the latch 21 so that the linkage member 31 is in the second position. In this way, a certain space can be given for the latch 21 to move downward, and then by pulling the pulling member 22, the latch 21 is moved away from the buckling position 11 and locked with the hanging arm 10. In this way, the latch 21 can be kept in the locked position away from the buckling position 11, so as to facilitate removing the hanging arm 10 from the wall panel 1; when it is necessary to unlock the latch 21, by pushing the linkage member 31, the latch 21 can be pushed to move towards the buckling position 11. The linkage member 31 moves to the first position, and the latch 21 is in the unlocked position where it is disengaged from the hanging arm 10, enabling the latch 21 to form a clamping space for clamping the wall panel 1 with the buckling position 11. In this way, the latch 21 and the buckling position 11 can jointly clamp the wall panel 1.

[0042] As Figure 5 , Figure 6 , Figure 7 and Figure 9 shown, in the embodiment of the present invention, a first sliding groove 12 is provided on the hanging arm 10, and a first convex portion 33 is provided on the linkage member 31. The first convex portion 33 is in sliding fit with the first sliding groove 12.

[0043] Through the above settings, the first convex portion 33 can slide in the extending direction of the first sliding groove 12 to limit the moving direction of the linkage member 31, so that the linkage member 31 can switch between the first position close to the latch 21 and the second position away from the latch 21, thereby facilitating the switching of the latch 21 between the unlocked position and the locked position.

[0044] It should be noted that in the embodiment of the present invention, the first sliding groove 12 and the first convex portion 33 are in clearance fit, and the two can slide relative to each other.

[0045] Specifically, in the embodiment of the present invention, the hanging arm 10 further includes two second sliding grooves 28, and two fifth convex portions 29 are provided on the linkage member 31. The two fifth convex portions 29 are in sliding fit with the two second sliding grooves 28. In this way, not only can the moving direction of the linkage member 31 be further limited, but also the linkage member 31 can move more stably.

[0046] As Figure 5 , Figure 6 , Figure 7 and Figure 9 shown, in the embodiment of the present invention, the latch 21 has a fixed position 210, and the fixed position 210 is located at one end of the latch 21 away from the buckling position 11. The latch component further includes an elastic member 24. One end of the elastic member 24 is connected to the hanging arm 10, and the other end of the elastic member 24 is connected to the fixed position 210.

[0047] Through the above arrangement, the elastic member 24 can make the lock buckle 21 tend to approach the buckle position 11, so that the lock buckle 21 can be maintained in the unlocked position close to the buckle position 11, so that the lock buckle 21 and the buckle position 11 can clamp the wall panel 1.

[0048] Specifically, in the embodiment of the present invention, the elastic member 24 is a spring.

[0049] Specifically, in an embodiment of the utility model, two through holes are provided on the hanging arm 10, and the hanging arm assembly also includes a fastener 25, which is passed through the two through holes and fixedly connected to the hanging arm 10, wherein one end of the elastic member 24 is connected to the fastener 25, and the other end of the elastic member 24 is connected to the fixed position 210.

[0050] Specifically, in the embodiment of the utility model, two third sliding grooves 26 are provided on both sides of the lock buckle 21, and the two third sliding grooves 26 are slidably matched with the fastener 25. In this way, the moving direction of the lock buckle 21 on the hanging arm 10 can be limited so that the lock buckle 21 can switch between the unlocked position and the locked position.

[0051] In the prior art, the inventors found that the distance between the display stand and the wall is relatively close, so it is difficult for the user to lay the wires, and thus it is difficult to realize the wiring function. Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in the embodiment of the utility model, the operating component 30 also includes a support member 32, which is located on the side of the linkage member 31 away from the lock buckle 21, and the support member 32 is rotatably arranged on the hanging arm 10. The support member 32 is rotated to an abutting state, and the support member 32 abuts against the linkage member 31. The support member 32 is rotated to a flattened state, and the support member 32 is arranged at an angle to the hanging arm 10.

[0052] In the above technical solution, by rotating the support member 32 to the flattened state, on the one hand, the support member 32 can form a certain angle with the hanging arm 10, so that the support member 32 can be supported on the wall surface. In this way, a certain angle and distance will be generated between the hanging arm 10 and the wall surface, which is convenient for the user to route wires to achieve the wire routing function. On the other hand, under the action of gravity, the linkage member 31 moves in a direction away from the lock 21, so that the linkage member 31 is in the second position. In this way, by pulling the pulling member 22, the lock 21 can be moved in a direction away from the buckling position 11, so that the lock 21 and the hanging arm 10 are locked, and thus the lock 21 can be kept in the locked position away from the buckling position 11, which is convenient for removing or installing the hanging arm assembly 2 from the wall panel 1. By rotating the support member 32 to the abutting state, the support member 32 can push the linkage member 31 to move in a direction close to the lock 21, so that the linkage member 31 can move to the first position, and the linkage member 31 can push the lock 21 to move in a direction close to the buckling position 11, so that the lock 21 and the hanging arm 10 are disengaged, so that the lock 21 is in the unlocked position, so that a clamping space capable of clamping the wall panel 1 is formed between the lock 21 and the buckling position 11. Compared with directly pushing the lock 21, by rotating the support member 32 to make the linkage member 31 push the lock 21 to move, the convenience of operation can be improved.

[0053] As Figures 5 to 11 shown, in the embodiment of the present invention, a first inclined surface 34 is provided on the linkage member 31. The first inclined surface 34 extends from the linkage member 31 in a direction close to the support member 32, and the first inclined surface 34 is inclined from the linkage member 31 in the direction of the hanging arm 10. The first inclined surface 34 can be in abutting cooperation with the support member 32.

[0054] In the above technical solution, in Figure 11 , by rotating the support member 32 clockwise, the end of the support member 32 facing the linkage member 31 can abut against the left end of the first inclined surface 34. At this time, by continuing to rotate the support member 32 clockwise, the end of the support member 32 facing the linkage member 31 moves from the left end of the first inclined surface 34 to the right end of the first inclined surface 34 and abuts against the right end of the first inclined surface 34. During the rotation process of the support member 32, the support member 32 can push the linkage member 31 to move in a direction close to the lock 21, so that the lock 21 and the hanging arm 10 are disengaged, so that the lock 21 is in the unlocked position, and thus a clamping space capable of clamping the wall panel 1 can be formed between the lock 21 and the buckling position 11.

[0055] It should be noted that in the embodiment of the present invention, as Figure 11 shown, the right end of the first inclined surface 34 is the end close to the hanging arm 10, and the left end of the first inclined surface 34 is the end far from the hanging arm 10.

[0056] As Figure 6 , Figure 8 , Figure 9 andFigure 11 As shown, in the embodiment of the present invention, a curved wall 35 is provided on one side of the support member 32 facing the linkage member 31 .

[0057] Through the above arrangement, the support member 32 is rotated to the abutment state, and the end of the support member 32 facing the linkage member 31 abuts against the first inclined surface 34. By setting the arc wall 35, the end of the support member 32 facing the linkage member 31 can slide more smoothly on the first inclined surface 34, so that the operation can be more convenient.

[0058] In one embodiment, the arc-shaped wall 35 can be configured as a flat surface.

[0059] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in an embodiment of the utility model, the support member 32 has a first end and a second end that are relatively arranged, the first end can abut against the linkage member 31, and the second end is provided with a second protrusion 37 protruding from the hanging arm 10, and the second protrusion 37 extends toward the side of the support member 32 away from the hanging arm 10, and the pivot point between the support member 32 and the hanging arm 10 is located between the first end and the second end.

[0060] In the above technical scheme, when wiring is required, the hanging arm assembly 2 is brought close to the wall, and the second protrusion 37 contacts the wall relative to the hanging arm 10 first. According to the lever principle, the supporting force of the wall can make the second end rotate around the pivot point in the direction close to the hanging arm 10, so that the first end of the support member 32 can rotate around the pivot point in the direction away from the hanging arm 10, and then the support member 32 can be disengaged from the linkage member 31, so that the support member 32 is no longer in abutment state. In this way, the linkage member 31 moves in the direction away from the lock buckle 21 under the action of gravity, so that the linkage member 31 moves to the second position, so that the pulling member 22 can be pulled to make the lock buckle 21 move in the direction away from the buckle position 11, so that the lock buckle 21 and the hanging arm 10 are locked. In this way, the lock buckle 21 can be maintained in the locked position away from the buckle position 11, so that the lock buckle 21 and the buckle position 11 can form a space for releasing the wall panel 1, so as to facilitate the removal of the hanging arm assembly 2 from the wall panel 1.

[0061] Furthermore, after the support member 32 is separated from the linkage member 31, under the action of gravity, the first end of the support member 32 continues to rotate around the pivot point in a direction away from the hanging arm 10, so that the support member 32 can be rotated to a flattened state, thereby facilitating wiring operations.

[0062] Specifically, in the embodiment of the present invention, the first end of the support member 32 is provided with the above-mentioned arc-shaped wall 35 .

[0063] Specifically, in the embodiments of the present utility model, there are two rotating holes 27 provided on the hanging arm 10, and two convex platforms 43 are provided on the support member 32. The two convex platforms 43 of the support member 32 are rotationally connected to the hanging arm 10 through the two rotating holes 27. Among them, the convex platform 43 is located between the first end and the second end of the support member 32.

[0064] Specifically, in the embodiments of the present utility model, the hanging arm 10 has a first plane 44. When the support member 32 rotates to the flattened state, the first plane 44 contacts the second convex portion 37. At this time, the first plane 44 limits the rotation angle of the support member 32, and the support member 32 cannot continue to rotate, so that the support member 32 is maintained in the flattened state, that is, the included angle between the first plane 44 and the support member 32 is 90°.

[0065] Specifically, in the embodiments of the present utility model, the support member 32 further includes a second plane 45, and the second convex portion 37 is higher than the second plane 45. In this way, the second convex portion 37 can contact the wall surface first to enable the support member 32 to rotate.

[0066] As Figures 5 to 9 shown, in the embodiments of the present utility model, a first side wall 13 is provided on the hanging arm 10, and a third convex portion 38 is provided at one end of the support member 32 facing the linkage member 31. The third convex portion 38 can abut against the first side wall 13 to keep the linkage member 31 in the first position.

[0067] In the above technical solution, by providing the third convex portion 38, when the support member 32 is switched from the flattened state to the abutting state, the third convex portion 38 can be abutted against the first side wall 13 to keep the support member 32 in the abutting state, that is, to keep the support member 32 in abutment with the linkage member 31. In this way, the linkage member 31 can be kept in the first position, so that the lock 21 is kept in the unlocking position away from the hanging arm 10. In this way, a clamping space capable of clamping the wall panel 1 can be formed between the lock 21 and the buckling position 11, so as to facilitate the installation of the hanging arm assembly 2 on the wall panel 1.

[0068] Specifically, in the embodiments of the present utility model, the third convex portion 38 and the first side wall 13 are in interference fit. When the third convex portion 38 abuts against the first side wall 13, a frictional force is generated, and the support member 32 is kept in the abutting state through the frictional force.

[0069] Specifically, in the embodiment of the present utility model, the distance between the second end of the support member 32 and the pivot point forms a power arm, and the distance between the first end of the support member 32 and the pivot point forms a resistance arm. Since the supporting force provided by the wall surface to the second end is greater than the frictional force generated between the third convex portion 38 of the support member 32 and the first side wall 13 of the hanging arm 10, in this way, the support member 32 can be rotated, and the third convex portion 38 can be separated from the first side wall 13. On the one hand, under the action of gravity, the first end of the support member 32 continues to rotate around the pivot point in a direction away from the hanging arm 10, so that the support member 32 can be rotated to a flattened state, which is convenient for wiring operation. On the other hand, under the action of gravity, the linkage member 31 is switched from the first position to the second position.

[0070] As Figures 5 to 9 shown, in the embodiment of the present utility model, a second side wall 14 is provided on the hanging arm 10, and a fourth convex portion 39 is provided on the lock 21; the lock 21 is slidably engaged with the hanging arm 10. When the lock 21 is moved to the locking position, the fourth convex portion 39 abuts against the second side wall 14. When the lock 21 is moved to the unlocking position, the fourth convex portion 39 is separated from the second side wall 14.

[0071] In the above technical solution, when the lock 21 is in the unlocking position, by pulling the pulling member 22, the fourth convex portion 39 can slide on the hanging arm 10 in a direction close to the second side wall 14, so that the fourth convex portion 39 moves to a position in contact with the second side wall 14 and generates a frictional force with the second side wall 14. In this way, the lock 21 can abut against the second side wall 14, so that the lock 21 is kept in a locked state away from the buckling position 11, which is convenient for removing the hanging arm assembly 2 from the wall panel 1; when the linkage member 31 drives the lock 21 to move in a direction away from the second side wall 14, the fourth convex portion 39 is separated from the second side wall 14, and the lock 21 can be in an unlocked state. In this way, a clamping space capable of clamping the wall panel 1 can be formed between the lock 21 and the buckling position 11.

[0072] Specifically, in the embodiment of the present utility model, the fourth convex portion 39 is provided in two.

[0073] Specifically, in the embodiment of the present utility model, when the lock 21 contacts the second side wall 14 to generate a frictional force, when the lock 21 is in the locking position, the pulling force provided by the elastic member 24 to the lock 21 is less than the frictional force between the lock 21 and the second side wall 14. In this way, the lock 21 can be fixed on the hanging arm 10, and the lock 21 is kept in the locking position.

[0074] As Figure 5 、 Figure 6 、 Figure 8 and Figure 9As shown, in the embodiment of the present utility model, the operating member 30 includes a linkage member 31. One side of the operating member 30 facing the latch 21 is provided with a first end face 41, and one side of the latch 21 facing the operating member 30 is provided with a second end face 42. There is a first distance between the first end face 41 and the second end face 42; when the latch 21 is in the unlocked position and the linkage member 31 is in the first position, along the moving direction of the latch 21, there is a second distance between the center point of the fourth convex portion 39 and the top end of the second side wall 14, and the first distance is less than the second distance.

[0075] If the first distance is set to be greater than the second distance, when the linkage member 31 switches from the second position to the first position, the linkage member 31 cannot contact the latch 21. In this way, the latch 21 cannot be switched from the locked position to the unlocked position. Therefore, in this embodiment, the first distance is set to be less than the second distance. During the process of the linkage member 31 switching from the second position to the first position, it can contact the latch 21 and push the latch 21 to move towards the direction close to the buckling position 11. In this way, the latch 21 can be switched from the locked position to the unlocked position, so that a clamping space capable of clamping the wall panel 1 can be formed between the latch 21 and the buckling position 11 to clamp the wall panel 1.

[0076] Specifically, in the embodiment of the present utility model, since the first distance is less than the second distance, pulling the pulling member 22 cannot make the center point of the fourth convex portion 39 contact the top end of the second side wall 14. In this way, the latch 21 and the second side wall 14 cannot generate frictional force, so that the wall panel 1 can be directly placed in the clamping space formed by the latch 21 and the buckling position 11 without performing locking and unlocking operations on the latch 21.

[0077] Preferably, in the embodiment of the present utility model, the fourth convex portion 39 is a cylinder, and the center point of the fourth convex portion 39 is the geometric center of the cylinder, that is, a point on the axis line of the cylinder; the top end of the second side wall 14 is the end of the second side wall 14 close to the buckling position 11.

[0078] In one embodiment, the fourth convex portion 39 can be an irregular structure, and the center of the fourth convex portion 39 is its geometric center.

[0079] As Figure 5 、 Figure 6 and Figure 12 shown, in the embodiment of the present utility model, a groove 36 for accommodating the elastic deformation position of the fourth convex portion 39 is provided between the fourth convex portion 39 and the latch 21. The fourth convex portion 39 is provided with a second inclined surface 40, and the second inclined surface 40 facilitates the fourth convex portion 39 to enter the second side wall 14.

[0080] In the above technical solution, by providing the groove 36, the fourth convex portion 39 can be elastically deformed in a direction close to the latch 21, so that the fourth convex portion 39 can slide into the space between the two second side walls 14 and abut against the second side walls 14; and by providing the second inclined surface 40, it is convenient for the fourth convex portion 39 to enter the second side wall 14; in this way, it is convenient to switch the latch 21 from the unlocked position to the locked position.

[0081] In one embodiment, the groove 36 may not be provided, and the fourth convex portion 39 may be made of rubber material.

[0082] Specifically, in the embodiment of the present invention, when the latch 21 is in the locked position, the fourth convex portion 39 and the second side wall 14 are in interference fit.

[0083] Such as Figure 5 、 Figure 6 、 Figure 8 and Figure 9 As shown in

[0084] With the above arrangement, when the linkage member 31 is in the second position, the phenomenon of interfering with the stroke of the latch 21 can be avoided, so as to avoid limiting the extreme position of the latch 21, and thus the latch 21 can be switched from the unlocked position to the locked position.

[0085] Specifically, in the embodiment of the present invention, the stroke of the latch 21 refers to the length of the third chute 26 in the moving direction of the latch 21.

[0086] Specifically, in the embodiment of the present invention, when the linkage member 31 is switched from the second position to the first position, the first end face 41 and the second end face 42 come into contact, which can push the latch 21 to move in a direction close to the buckling position 11. At this time, the pushing force for pushing the latch 21 is greater than the frictional force between the fourth convex portion 39 of the latch 21 and the second side wall 14 of the hanging arm 10, and the latch 21 is switched from the locked state to the unlocked state. After the hanging arm assembly 2 contacts the wall panel 1, the function of automatic locking is realized, thereby realizing the operation process.

[0087] Specifically, in the embodiment of the present invention, the latch 21 further includes a third inclined surface 23, and when the hanging arm assembly 2 is installed on the wall panel 1, the third inclined surface 23 automatically buckles after contacting the wall panel 1.

[0088] Specifically, in the embodiments of the present utility model, the linkage operation of the support member 32 and the linkage member 31 with the lock 21 can be used to achieve the switching between the locked state and the unlocked state, and can also achieve the function of wiring.

[0089] As Figure 3 and Figure 4 shown, the embodiments of the present utility model provide a monitor bracket. The monitor bracket includes a wall panel 1 and the above-mentioned hanging arm assembly 2, and the hanging arm assembly 2 is installed on the wall panel 1.

[0090] The above-mentioned monitor bracket has all the advantages of the above-mentioned hanging arm assembly 2, which will not be elaborated here.

[0091] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: By pulling the pulling member, the lock moves away from the buckling position, so that the lock and the hanging arm are locked and matched, so that the lock can be kept at the locking position away from the buckling position. In this way, a space for releasing the wall panel can be formed between the lock and the buckling position, so as to facilitate the removal of the hanging arm assembly from the wall panel. Compared with the need to continuously pull the pulling member to remove the hanging arm assembly, in the present utility model, the hanging arm assembly can be removed from the wall panel without continuously pulling the pulling member, thereby making the operation of removing the hanging arm assembly more convenient.

[0092] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
