Detailed Description

The following describes specific embodiments of the utility model with reference to the drawings and examples:

it should be noted that the structures, proportions, sizes, etc. shown in the drawings are merely for the purpose of understanding and reading the disclosure, and are not intended to limit the scope of the utility model, which is defined by the appended claims.

Also, the terms such as "upper," "lower," "left," "right," "middle," and "a" and the like recited in the present specification are merely for descriptive purposes and are not intended to limit the scope of the utility model, but are intended to provide relative positional changes or modifications without materially altering the technical context in which the utility model may be practiced.

Embodiment 1, in combination with fig. 1, this embodiment provides a writing board suspension latch, including first hasp body 1, second hasp body 2 and with the suspension member 5 that writing board hung, the one end of first hasp body 1 and second hasp body 2 is through fixed knot structure connection formation closed end, is provided with suspension member connection structure on the closed end, and suspension member 5 passes through suspension member connection structure and closed end connection, and the other end of first hasp body 1 and second hasp body 2 forms the open end at interlock writing board border, be provided with on the corresponding open end inboard of first hasp body 1 and second hasp body 2 and be used for realizing stable interlock limit structure 3 with writing board border cooperation. The writing board edge is inserted from the opening end of the hanging lock catch, the writing board edge is firmly clamped by the hanging lock catch through the limiting structure 3 arranged by the hanging lock catch, in addition, the hanging piece connecting structure is arranged on the closed ends of the first lock catch body 1 and the second lock catch body 2, and under the condition that the writing board edge is firmly clamped by the hanging lock catch, the hanging piece 5 penetrates through the hanging piece connecting structure to hang the writing board on the wall body. The writing board can be hung on the wall body only through the hanging lock catch without arranging a mounting hole.

The limit structure 3 is a limit step for abutting the edge of the writing board. The surface of the limit step is abutted against the edge of the writing board. In an embodiment, the limit step is inclined to the limit face of the tablet edge contact, since the tablet edge has a certain arc, in order to make a better abutment of the limit step with the tablet edge, the step thereof is provided with an inclination matching the arc of the tablet edge. The further abutting of the limit step and the edge of the writing board greatly improves the clamping force of the hanging lock catch on the writing board.

The middle part of the opening end is provided with a yielding groove 6, the yielding groove is formed into a space for accommodating the edge of the writing board after the first lock catch body 1 and the second lock catch body 2 are connected, and further, the accommodating space is matched with the shape of the edge of the writing board. According to the writing board, the abdication groove 6 is formed in the middle of the first lock catch body 1 and the second lock catch body 2 according to the shape of the writing board edge, the containing space formed by the abdication groove 6 is consistent with the writing board edge, and when the hanging lock catch clamps the writing board, the writing edge is completely clamped into the containing space, so that the writing board is prevented from falling off from the hanging lock catch.

The inner sides of the opening ends of the first lock catch body 1 and the second lock catch body 2 are provided with anti-slip structures 4. Specifically, the anti-slip structure 4 is a plurality of anti-slip stripes which are arranged in parallel, and the arrangement direction of the anti-slip stripes is perpendicular to the suspension direction of the writing board. The reason for the writing board sliding off is that the friction force between the hanging lock catch and the writing board is smaller than the gravity action of the writing board. The main purpose of the anti-slip stripes is thus to increase the friction between the suspension catches and the writing tablet, which is arranged in a direction perpendicular to the suspension direction of the writing tablet, which increases the friction between each other to a maximum extent.

The fixed knot constructs for the bolt, first hasp body and second hasp body correspond respectively and set up screw 10, realize hanging the hasp to the adjustment of writing board edge interlock degree through the cooperation of bolt and screw 10. The adjustment of the engagement degree of the hanging lock catch on the edge of the writing board is realized by adjusting the tightening degree of the bolt. Although bolts are not shown in fig. 1, bolts are installed in the screw holes 10. The first lock catch body 1 and the second lock catch body 2 are tightly connected by screwing the bolts, the open ends are firmly meshed when being inserted into the edges of the writing board, and the edges of the writing board are completely embedded into the accommodating space. When the bolt is unscrewed, the hanging lock catch can be easily detached from the writing board.

The closing end is further provided with a clamping structure, the clamping structure comprises a clamping concave 8 and a clamping convex 7, the clamping concave 8 is located on the first lock catch body 1, the clamping convex 7 is located on the second lock catch body 2, and the clamping convex 7 and the clamping concave 8 are engaged when the first lock catch body 1 and the second lock catch body 2 are closed. The clamping concave 8 on the first lock catch body 1 and the clamping convex 7 on the second lock catch body 2 are matched with each other, so that the problem that the clamping force of the hanging lock catch on the writing board is reduced due to dislocation between the first lock catch body 1 and the second lock catch body 2 is prevented.

The hanging piece connecting structure is a through hole, and the through hole is formed by correspondingly arranging grooves 9 on the first lock catch body 1 and the second lock catch body 2. The suspension element is a closed loop metal loop. The first latch body 1 and the second latch body 2 are connected by a fixing structure, and then the grooves 9 of the first latch body and the second latch body form through holes, and the hanging piece penetrates through the through holes to be connected with the closed end. The opening end of the hanging lock catch is meshed with the edge of the writing board, and then the writing board is hung on the wall body through the hanging piece.

Many other changes and modifications may be made without departing from the spirit and scope of the utility model. It is to be understood that the utility model is not to be limited to the specific embodiments, but only by the scope of the appended claims.
