Detailed Description

The following describes the embodiments of the present utility model further with reference to the attached drawings; the following examples are illustrative of the utility model and are not intended to limit the scope of the utility model. And the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be made by one of ordinary skill in the art without the need for inventive faculty, are within the scope of the present disclosure, based on the described embodiments of the present disclosure.

Unless defined otherwise, technical or scientific terms used in this disclosure should be given the ordinary meaning as understood by one of ordinary skill in the art. The use of the terms "comprising" or "includes" and the like in this disclosure is intended to cover an element or article listed after that term and equivalents thereof without precluding other elements or articles.

Referring to fig. 1, in one embodiment, the connecting portion 5 is provided with a threaded hole 8 along the axis and the retaining and anti-disengaging portion 6 is disposed at a side of the threaded hole 8 and is fixedly connected with the connecting portion 5 by welding or an integrally formed manner. By this arrangement, the connecting portion 5 can perform a connecting function through the screw hole 8, and the retaining and anti-releasing portion 5 can perform a mounting and fixing function on itself.

Referring to fig. 1, in one embodiment, the retaining and anti-disengaging portion 6 is a spring plate 9, on a central plane of a through hole axis of the threaded hole 8, a point where the spring plate 9 is connected with the connecting portion 5 is a corner point, an end point where the spring plate 9 is far away from the connecting portion 5 is a free point, and an included angle between a connecting line of the corner point and the free point and the hole axis is an acute angle. After the connecting part 5 and the anti-back and anti-falling part 6 are installed, the elastic piece 9 is not easy to reversely fall off after being installed due to the angle of the elastic piece.

Referring to fig. 2, an assembled apartment bed includes a fixing frame, an assembly part 2 and a connecting piece, wherein a mounting hole is formed in the fixing frame, a plurality of axial inner holes 3 are formed in the assembly part 2 and used for providing mounting positions for the connecting portions 5, the number of the axial inner holes 3 is the same as that of the connecting portions 5, the connecting piece comprises screws and pipe connecting pieces, the pipe connecting pieces are mounted in the axial inner holes 3, the screws penetrate through the mounting hole and are in threaded connection with the threaded holes 8, and the anti-back anti-falling portions 6 are used for preventing the connecting portions 5 from falling out of the axial inner holes 3.

Referring to fig. 3, 4 and 5, the anti-back-out portion 6 can be locked into the axial bore 3, i.e., the connecting portion 5 can be inserted into the axial bore 3 through the anti-back-out portion 6. The connecting part 5 enters the axial inner hole 3 along the axial direction of the connecting part, and one end of the retaining and anti-falling part 6 connected with the connecting part 5 firstly enters the axial inner hole 3 along the axial direction of the connecting part. In one embodiment, the periphery of the notch of the axial inner hole 3 protrudes toward the center, and the anti-withdrawal portion 6 in the axial inner hole 3 is limited. The periphery of the elastic sheet 9 extends out of a part obliquely upwards, the area of the anti-backing-off prevention part 6 is larger than the area of the notch of the axial inner hole 3 when the connecting part 5 is seen in the axial direction, and the arrangement is that the inclined surface part around the elastic sheet 9 contacts with the notch of the axial inner hole 3, so that the elastic sheet 9 is more convenient to be pressed into the axial inner hole 3 under the action of human force, and the elastic sheet 9 enters the axial inner hole 3 and is more difficult to separate from the axial inner hole 3 due to the acting force provided by the inclined surface of the elastic sheet 9. Further, the above state can be achieved by setting the material and thickness of the elastic sheet 9, that is, the elastic sheet 9 can be slightly deformed to be squeezed into the axial inner hole 3 under the manual pressing.

Referring to fig. 1, in one embodiment, two elastic pieces 9 are fixedly disposed on each connecting portion 5, and when two elastic pieces 9 on the same connecting portion 5 enter the axial inner hole 3, the two elastic pieces 9 are respectively located at the notch and the groove bottom of the axial inner hole 3, so that the elastic pieces 9 cannot slide any more and possibly escape from the axial inner hole 3. The two elastic sheets 9 are arranged in such a way that the central axis of the connecting piece cannot deviate after being clamped into the working position, so that the stability of the connecting effect is improved; and the structure of the anti-back-off part 6 is ensured by one more step, even if the first elastic sheet 9 is separated from the axial inner hole 3, the second elastic sheet 9 can play a role in connection, so that the danger of a user when the user installs the assembly 2 at the upper and lower positions is avoided.

Referring to fig. 5, in one embodiment, a plurality of positioning strips 4 are disposed in each of the axial inner holes 3 in a protruding manner, and each of the spring plates 9 is provided with the same number of positioning holes 7, and the positioning holes 7 are connected with the positioning strips 4 in a clamping manner, and the shapes and positions of the positioning strips are corresponding to each other. The positioning strip 4 can limit the rotation of the elastic sheet 9 through the positioning hole 7 after the elastic sheet 9 enters the axial inner hole 3, so that the elastic sheet 9 is prevented from rotating in the axial inner hole 3, and noise is generated.

Referring to fig. 2 and 5, the axial inner hole is a shrinkage hole, so that space is effectively saved and materials are saved.

The following description of the steps of the utility model follows:

s1, after a worker transfers the assembly part 2 and the fixing frame to a destination, taking out the pipe connecting piece and the screw;

s2, pressing the anti-back-off part 6 on the connecting part 5 into the axial inner hole 3 on the assembly part 2;

s3, using a screw to penetrate through a mounting hole of the fixing frame and be screwed into the threaded hole 8 on the connecting part 5, and fixing the assembly part 2 on the fixing frame;

and S4, when the assembly part 2 is required to be disassembled, the assembly part 2 can be disassembled by unscrewing a screw.
