Abstract

The utility model relates to a multi-angle rotatable and retractable hanging bracket used in a liquid crystal TV or an LCD (liquid crystal display), which mainly comprises a base, an upper support, a lower support, a first connecting rod, a second connecting rod and a fixed bracket. The upper support and the lower support can be fixed on the round convex hall of the base through a bolt and form a rotating mechanism (Z); the lower support, the first connecting rod, the second connecting rod and the fixed bracket are connected in turn though a socket head screw, a copper pad and a special screw, and form a rotating mechanism (Y2), a rotating mechanism (Y1) and a rotating mechanism (X). The liquid crystal TV and the LCD are connected with the fixed bracket by a screw, and after collecting the liquid crystal TV or the LCD, the base of the hanging bracket is nailed on a wall or a susceptive board by a metal expanded screw and then tightly fixed by a nut. Through the relatively rotating movement among the four rotating mechanisms, the rotation and expansion of the liquid crystal TV or the LCD connected with the hanging bracket in multi-direction of the space can be achieved.

Description

But multi-angle rotation and flexible wall hanging frame

Technical field

The utility model relates to a kind of wall hanging frame, detailed it, refer to especially a kind ofly LCD TVs or liquid crystal display to be coupled together and can need be installed on the wall with the user, but and multi-angle rotation and flexible wall hanging frame.

Background technique

Now LCD TVs and display device generally adopt base to be placed on form on the desktop, adopt also having of wall hanging mode, but its angle of swing is smaller, rotary freedom is few, so the angle of swing that realizes and and function such as sense of rotation on be subjected to suitable restriction in addition, influenced the effect of watching and the convenience of use.

The model utility content

But the technical problems to be solved in the utility model provides a kind of multi-angle rotation and flexible wall hanging frame, can realize the rotation of a plurality of directions and flexible, and its angle of swing is enough big, the deficiencies in the prior art have been remedied, satisfied user's multi-angle, multi-faceted demand of watching LCD TVs or liquid crystal display.

But the technical solution of the utility model provides a kind of multi-angle rotation and flexible wall hanging frame, it mainly comprises pedestal 1, upper bracket 2, undersetting 3, head rod 4, second connecting rod 5 and analog bracket 6, it is characterized in that: pedestal 1 is mounted on described wall hanging frame on the wall by expansion of metal screw 9 and nut 10, there is the corresponding circular hole of two rows upper bracket and undersetting can be fixed by bolts on the circular convex closure on the pedestal 1 on upper bracket 2 and the undersetting 3, and formation rotating machinery Z, undersetting 3, the head rod 4 and second connecting rod 5 are by socket head screw 13, copper backing I12 links to each other successively with special screw hole I11 and forms rotating machinery Y2 and rotating machinery Y1, second connecting rod 5 and analog bracket 6 are by socket head screw 13, two copper backing II15 link to each other with special screw hole II14 and form rotating machinery X, and analog bracket 6 and LCD TVs or liquid crystal display (7) are connected together with screw by its corresponding mounting hole.

Four rotating machinerys in this wall hanging frame adopt socket head screw, copper backing and the mode that the special screw hole is connected, and big coupling mechanism force is arranged, and the frictional force that this Connecting format produces can be born bigger turning torque and pulling force, and it is attractive in appearance that outward appearance is had more.By pulling the correlated parts of this wall hanging frame, can realize being attached at rotation on a plurality of directions in space of LCD TVs on this wall hanging frame or liquid crystal display and flexible.

The wall hanging frame that provides of the present utility model rotatablely moves by four rotating machinerys, has realized rotation on multi-direction of LCD TVs or liquid crystal display and flexible.This wall hanging frame is simple and reasonable, is guaranteeing to make in safe in utilization the watcher can adjust LCD TVs or the liquid crystal display orientation to various needs easily.

Embodiment

Below by a specific embodiment the utility model is described in further detail, but the utility model is not limited to this specific embodiment.

But consult accompanying drawing 1 rotation of the utility model multi-angle and flexible wall hanging frame as can be known, mainly comprise pedestal 1, upper bracket 2, undersetting 3, head rod 4, second connecting rod 5 and analog bracket 6 link by certain union piece between each major part, have formed four independently rotating machinerys.LCD TVs is connected with analog bracket 6 by screw 16 with liquid crystal display, connect LCD TVs or liquid crystal display after, the pedestal of wall hanging frame at wall or above the plank that can be stressed, uses nut 10 fastening by 9 dozens on expansion of metal screw again.

Cooperate Fig. 2 as can be known, a circular convex closure 17 is arranged on the utility model pedestal 1, two corresponding screwed holes are respectively arranged on upper bracket 2 and the undersetting 3, upper bracket 2 and undersetting 3 can be fixed on the circular convex closure 17 on the pedestal 1 with the corresponding bolt 8 of this hole size with two, form a rotating machinery Z, its angle of swing can be arbitrarily angled.The shape of pedestal 1 can be as shown in Figure 2 square, also can be shapes such as rhombus, circle, ellipse, and the position and the number that are used to the U type mounting hole of locating on the pedestal can design as required.

Cooperate Fig. 3 and Fig. 4 as can be known, undersetting 3, head rod 4 and second connecting rod 5 link to each other successively by socket head screw 13, copper backing I12 and special screw hole I11 and form two independently rotating machinery Y2 and rotating machinery Y1.The left end of the right-hand member of undersetting 3, head rod 4 two ends and second connecting rod 5 is a circular arc, like this rotating machinery Y1 and rotating machinery Y2 when rotated each part can not collide, and undersetting 3 is along 0～180 ° of Y2 axle rotation relatively for head rod 4, and second connecting rod 5 head rod 4 relatively rotates 0～180 ° along the Y1 axle.The effect of copper backing mainly provides enough frictional force, and the size of frictional force can change by the tightness of adjusting socket head screw.

Cooperate Fig. 5 as can be known, two analog brackets 6 of layout in second connecting rod, 5 both sides symmetries, link to each other with special screw hole II14 and form rotating machinery X by socket head screw 13, two copper backing II15, the hole at two ends, described second connecting rod, 5 left and right sides becomes spatial vertical to arrange, this has just guaranteed that the running shaft of rotating machinery X and the running shaft of rotating machinery Y1 also become spatial vertical to distribute.The position of the shape of analog bracket 6 and its mounting hole can be according to the flexible design that requires of LCD TVs or liquid crystal display, and the number of the mounting hole of each analog bracket 6 can be 2～8.

Requirement design according to above embodiment has formed four rotating machinerys, can three directions rotate around the space, can realize the flexible of LCD TVs and liquid crystal display again by the relative rotation between four rotating machinerys.Can increase a little lubricant oil so that rotate at each rotating machinery place along sliding, before being installed on the wall, the user to screw the socket head screw 13 of rotating machinery X to LCD TVs or display device, assurance has bigger frictional force, can bear the turning torque (M＞50N.m) of LCD TVs or liquid crystal display, after being installed in LCD TVs or liquid crystal display on the wall, whether the frictional force of checking each rotary joint place is even, at last everywhere screw is tightened, the user just can adjust the orientation according to the needs of oneself.

It should be noted that and when the function of its generation and effect do not exceed the design of specification of the present utility model and accompanying drawing, all limit with claim of the present utility model if conceive the structural change of being done according to the utility model.
