Description

Hook fitting

Technical Field

The utility model relates to a technical field is fixed in the installation of frame particularly, relates to a couple accessory.

Background

In order to fix the picture frame on the display wall or the wall surface, hook corner connectors are required to be installed on the back surface of the picture core plate, so that the picture frame can be hung on fixing nails or fixing hooks which are arranged on the display wall or the wall surface in advance through the hook corner connectors. The hook corner brace commonly used at present mainly comprises two parts: one part is a flat plate part which is fixed on the back of the picture core plate through screws; the other part is a suspended part, a hanging hole is arranged on the suspended part, the hanging hole is generally formed by a large hole part and a small hole part which are communicated, and the head of a fixed hook on the wall or the wall surface enters the suspended part through the large hole part and then slides to the small hole part to realize locking.

The design of the traditional hook corner fastener is that the picture frame is designed to be fixed along the wall surface, however, for the superposed decorative picture frame or the large-size picture frame, the back plate part of the picture core plate in the combined state is not necessarily positioned on the same plane, and the traditional hook corner fastener is not suitable for the structure that the back surface of the picture core plate has a certain distance with the wall surface. In addition, the whole picture frame is large in size, and the hanging holes of the conventional hook corner connectors are small, so that the picture frame cannot be quickly positioned on a fixed hook on a wall when in use, and the installation is inconvenient; and if the size of the hanging hole is directly made large, the stability of installation is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a be applicable to stack formula frame or jumbo size frame couple angle sign indicating number, simple structure is but stability is good, and fixes a position more accurate, the installation of being convenient for when using.

The purpose of the utility model is realized like this:

the utility model provides a couple accessory for hang on the couple on the stationary plane make the object of being connected with fix on the stationary plane, the couple accessory is the cell body structure that the cross-section is "M" type, includes: the mounting structure comprises a first wall surface and a second wall surface which are parallel to each other, wherein the first wall surface and the second wall surface respectively extend outwards from the bottoms of the first wall surface and the second wall surface at an angle of 90 degrees to form a first mounting surface and a second mounting surface respectively, and mounting holes are formed in the first mounting surface and the second mounting surface; the fixing member is formed on the tops of the first wall surface and the second wall surface and stretches across the two wall surfaces, the middle of the fixing member is sunken to a certain height towards the bottom directions of the first wall surface and the second wall surface, so that a groove with a groove line parallel to the first wall surface is formed in the middle of the fixing member, a notch is cut in the bottom surface of the groove, and the outer edge of the notch is in a sawtooth shape.

During the use, will the couple accessory is fixed at the back of drawing the core board through two installation faces, hangs fixed component on the coupler body of fixed hook, carries on spacingly through the sawtooth of recess breach outward flange, prevents to move about the frame, also makes the frame when the installation more easy accurate hanging. The sawtooth is hung on the inner slope of the hook body of the hook and is close to the wall surface under the influence of gravity after being hung on the wall, so that the upper surface (namely the surfaces on the two sides of the groove) of the fixing component is attached to the wall surface, and the upper surface and the wall surface form a contact surface to enable the whole body to be parallel to the wall surface to form attaching force.

Preferably, an upper surface of the fixing member is a plane perpendicular to the first wall surface and the second wall surface.

Preferably, the groove bottom width of the groove is smaller than the notch width of the groove. As an example, the cross section of the groove may be designed as a trapezoid.

Preferably, the depth of the groove is slightly smaller than the slope thickness of the hook body of the hook. The saw teeth can just fall on the slope surface of the hook, and the stability is better.

Drawings

Further advantages and features of the invention are illustrated by the following description of an embodiment of the invention, given by way of example and not by way of limitation, with reference to the accompanying drawings, in which:

fig. 1 is a schematic side view of a preferred embodiment of the hook assembly of the present invention.

Fig. 2 is a top view of the embodiment shown in fig. 1.

Fig. 3 is a schematic structural diagram of the embodiment shown in fig. 1 applied to fixing of a superimposed picture frame.

Detailed Description

As shown in fig. 1, the hook fitting 1 is a groove structure having an "M" shaped section, and includes: the first wall surface 11 and the second wall surface 12 which are parallel to each other extend outwards from the bottom of the first wall surface 11 and the bottom of the second wall surface 12 at an angle of 90 degrees to form a first mounting surface 110 and a second mounting surface 120 respectively, and two mounting holes 14 are formed in the first mounting surface 110 and the second mounting surface 120 respectively. A fixing member 13 is formed on the top of the first wall 11 and the second wall 12 to cross the two walls, and as shown in fig. 2, the middle of the fixing member 13 is recessed toward the bottom of the first wall 11 and the second wall 12 by a certain height h, so that a groove 131 is formed in the middle of the fixing member 13, the groove line of which is parallel to the first wall 11. The groove 131 has an inverted trapezoidal cross section with a groove bottom width less than the slot width. The bottom surface of the groove 131 is cut with a notch, and the outer edge 132 of the notch is designed to be serrated. The upper surface 130 of the fixing member 13 located on both sides of the recess 131 is a plane perpendicular to the first wall surface 11 and the second wall surface 12.

Use utility model in the fixed of stack formula frame product. The superposed picture frame is formed by combining two picture frames which are overlapped, as shown in fig. 3, the picture frame 21 is fixed close to a wall, but the back surface of the picture core plate 3 of the picture frame 22 which is overlapped with the picture frame 21 is separated from the wall by a certain distance. Therefore, adopt the utility model discloses cooperation no trace nail 5 is fixed. As shown in fig. 3, the hook fitting 1 is fixed on the back of the picture frame 22 on the drawing core plate 3 by the first mounting surface 110 and the second mounting surface 120 through the screws 4, then the fixing member 13 is hung on the hook body of the traceless nail 5, and the fixing member is limited by the saw teeth on the notch outer edge 132 of the groove 131, so that the picture frame is prevented from moving left and right, and the picture frame is also easily and accurately hung during mounting. The depth h of the groove 131 is preferably slightly less than the slope thickness of the hook body of the traceless hook 5, so that the saw teeth can just fall on the slope surface of the hook body, and the stability is better. The inner slope position of the hook body of the traceless nail 5, where the sawteeth are hung, can approach the wall surface under the influence of gravity after being hung on the wall, so that the upper surface 130 (namely, the surfaces on two sides of the groove) of the fixing member 13 is attached to the wall surface, and the upper surfaces 130 on two sides and the wall surface form contact surfaces to form an attaching force parallel to the wall surface integrally.

Although the present invention has been described in terms of the preferred embodiments, it is not intended that the scope of the invention be limited to the exact construction and arrangement shown and described, and it is intended that all equivalent alterations and modifications that can be devised readily by those skilled in the art based on the foregoing description be embraced by the scope of the invention.
