There are many ways to connect the fixing arm 110 to a wall, such as by screws, snaps, etc. The first support arm 120 may also take many forms, such as a column, a rod, etc., for example, a long strip. One end of the first support arm 120 is fixedly connected to the fixed arm 110, and the other end extends away from the fixed arm 110, and the two ends are connected in a plurality of manners, such as by screws, buckles, clamping grooves, etc., and in some embodiments, in order to improve the strength of the support 100 and simplify the connection process, the fixed arm 110 and the first support arm 120 are integrally formed. The first supporting arm 120 and the fixed arm 110 are disposed at an angle of 80 ° to 100 °, for example, 90 °. It should be noted that, in some embodiments, for example, the weight of the support frame 100 is reduced, and a hollow structure may be formed on the support frame 100. The mounting position is disposed at one end of the first support arm 120 far away from the fixed arm 110, and the through hole 121 penetrates through the first support arm 120, so that the upper side and the lower side of the first support arm 120, which are oppositely disposed, are communicated, wherein the mounting position for mounting the support block 200 is disposed on the upper side.
The shape of the support block 200 may be varied, such as square, triangular, etc., and is exemplified by a circular configuration. The support block 200 may be made of a variety of materials, such as stainless steel. The bottom surface of supporting shoe 200 is installed on the installation position, and the shape of top surface can be with waiting the shape adaptation at support piece top, so, is favorable to waiting to support the piece better. The support piece to be supported is placed on top of the support block 200, and the support block 200 supports the support piece to be supported. The middle part of supporting block 200 is formed with spacing through-hole 210, is provided with internal thread 211 in the spacing through-hole 210, with the external screw thread 331 adaptation on the fastening portion 330, namely under a certain state of hanging the support, fastening portion 330 can with spacing through-hole 210 threaded connection, and avoid fastening knob 300 dropping under the effect of gravity.
The radial dimension of the stopper 310 of the fastening knob 300 is greater than the aperture of the through hole 121, so that the stopper 310 may remain under the first connection arm when the fastening portion 330 is fixed with the support to be fitted through the through hole 121 and the support block 200, thereby fixing the support to be fixed on the first connection arm. The shape of the stopper 310 may be varied, such as circular, square, etc., and is exemplified by a cylindrical or disk-shaped configuration. The overall shape of the limiting portion 320 and the fastening portion 330 may be many, for example, a cylindrical shape is taken as an example, and the outer side wall of the fastening portion 330 has an external thread 331, where the external thread 331 may be matched with the internal thread 211 in the limiting through hole 210 or may be matched with the internal thread 211 on the to-be-supported member. The stopper portion 310, the stopper portion 320, and the fastening portion 330 may be integrally formed.
In this embodiment, during the use of the wall hanging bracket, the wall hanging bracket has an idle state and a working state, in the idle state, the fastening portion 330 passes through the through hole 121 to be matched with the internal thread 211 in the limiting through hole 210, and in the case that the fastening knob 300 is not matched with the to-be-supported piece (or in the case that the to-be-supported piece is not mounted), the fastening knob 300 is not dropped due to the action of gravity, so that the wall hanging bracket can be stably mounted on the support frame 100; in the working state, the fastening part 330 passes through the through hole 121 and the limiting through hole 210 to be fixedly connected with the to-be-supported piece, and the limiting part 320 is positioned in the limiting through hole 210, at this time, the fastening part 330 is only fixedly connected with the to-be-supported piece and is no longer connected with the threads in the limiting through hole 210, so that the internal threads 211 in the limiting through hole 210 do not bear the load applied by the to-be-supported piece when the to-be-supported piece is installed, and damage to the internal threads 211 due to overload bearing is avoided, thereby being beneficial to prolonging the service life of the support block 200; meanwhile, in the working state, the supporting block 200 is only subjected to the pressure exerted by the to-be-supported piece (clamping of the first supporting arm 120 and the to-be-supported piece), and does not bear radial load, so that stable working of the supporting block 200 is facilitated.
In some embodiments, in order to achieve adjustment of the deflection angle of the support, the mounting position includes a support boss 500, and a top surface 510 of the support boss 500 is a convex arc surface; the bottom of the supporting block 200 is provided with a deflection groove 230, the inner side wall of the deflection groove 230 is provided with a concave arc surface, and the concave arc surface is provided with a convex arc surface, so that the supporting block 200 can deflect relative to the supporting boss 500.
Specifically, in this embodiment, the entire shape of the supporting boss 500 is a truncated cone, or is a partially spherical surface, and the via hole 121 penetrates the supporting boss 500. The top surface 510 of the supporting boss 500 may be a convex arc surface, which may be a convex partial sphere, and the sidewall of the deflection groove 230 at the bottom of the supporting block 200 may be a concave arc surface, which may be a concave partial sphere. The arc degrees of the convex arc surface and the concave arc surface are equivalent, so that the deflection groove 230 can be attached to different positions of the top of the support boss 500, and the support block 200 can be stably and reliably connected with the support boss 500 at a plurality of angles. In this way, a stable state in which the support side of the support block 200 has a plurality of different angles can be achieved, and when the support to be supported is installed at the support side, the support to be supported can be made to have different deflection angles. Taking a projector as an example, the supporting side of the supporting block 200 supports the top of the projector, the fastening knob 300 is in threaded connection with the bottom of the projector casing, and when the projector needs to adjust the deflection angle, the deflection angles of the supporting block 200 and the fastening knob 300 can be integrally adjusted compared with the deflection angles of the supporting boss 500, so that the orientation of the supporting side of the supporting block 200 is changed, and the adjustment of the projector angle is realized. By setting the contact surface to the arc surface, the stability of the cooperation of the support block 200 and the support boss 500 can be ensured in the case of a plurality of angles while ensuring a sufficient contact area. It should be noted that, in some embodiments, in order to simplify the connection process between the support boss 500 and the first support arm 120, the support boss 500 is located at an end of the first support arm away from the fixed arm 110, and is integrally formed with the first support arm 120. In this way, the connection strength of the support boss 500 and the first support arm is improved while the installation process is greatly simplified.
In some embodiments, in order to improve the compactness of the structure and the stability of installation, a side of the supporting boss 500 opposite to the supporting block 200 is provided with a avoiding groove 520, and at least a part of the limiting portion 320 may be received in the avoiding groove 520. The inner side wall of the avoidance groove 520 is provided with a concave arc surface, the wall hanging bracket further comprises a first buffer cushion 610, and the first buffer cushion 610 is arranged between the stop part 310 and the inner side wall of the avoidance groove 520; the first cushion 610 has a convex arc surface on a side facing the escape groove 520, and a side facing the stopper 310 is in contact with the stopper 310.
Specifically, in the present embodiment, the side of the support boss 500 facing the fastening knob 300 is formed with a relief groove 520, and the groove wall surface of the relief groove 520 corresponds to the shape of the top surface 510 of the support boss 500. When the fastening knob 300 is engaged with the supporting block 200 or the to-be-supported member, the fastening part 330, the limiting part 320, and the stopper part 310 move upward. The radial dimension of the stopping portion 310 is smaller than that of the notch of the avoidance groove 520, when the fastening knob 300 is connected with the supporting block 200 or the to-be-supported piece, the stopping portion 310 can be at least partially positioned in the avoidance groove 520, so that the compactness of the structure is improved, meanwhile, the influence of the external environment on the stopping portion 310 is reduced as much as possible, the stability of the fixing of the stopping portion 310 is improved, and the stability of the fastening knob 300 in operation is ensured. The overall shape of the first cushion 610 may be quite large, taking a partial sphere as an example, the convex arc surface at the top of the first cushion is equivalent to the concave arc surface curvature in the avoidance groove 520, so that the first cushion 610 can be attached to the inner side wall of the avoidance groove 520 under various conditions (multiple positions). The side of the first cushion pad 610 facing the stopper portion 310 is a plane, and the portion of the stopper portion 310 facing the first cushion pad 610 is a plane, and when the fastening knob 300 is fastened, the first cushion pad 610 is attached to the stopper portion 310. The first cushion pad 610 is provided with a first coupling hole 611, and the fastening portion 330 and the limiting portion 320 pass through the first coupling hole 611. The first buffer pad 610 is made of an elastic material, and prevents the stopper 310 (made of a hard material, such as metal) from directly contacting the support boss 500 (made of a hard material, such as metal), thereby advantageously improving the installation stability of the structural knob.
Of course, in some embodiments, to improve the stability of installation, the wall hanging bracket further includes a second cushion pad 620, and the second cushion pad 620 is disposed between the support block 200 and the support boss 500; one side of the second buffer is attached to the side wall of the concave arc-shaped deflection groove 230, and the other side is attached to the top surface 510 of the convex arc-shaped support boss 500. In this embodiment, the second cushion 620 is a hollow partial sphere, and the upper surface and the lower surface of the second cushion are both cambered surfaces. The upper surface is convex arc setting and is jointed with the inner side wall of the avoidance groove 520, and the lower surface is concave arc surface and is jointed with the convex arc surface of the support boss 500. The second buffer pad 620 is provided with a second matching hole 621, and the fastening part 330 and the limiting plate pass through the second matching hole 621 to be matched with the supporting block 200 and the to-be-supported piece, so that the installation stability of the second buffer pad 620 is improved.
