Description

The present invention relates to a sleeve assembly in which a sleeve is fixed to a pipe body. In particular, the present invention relates to a sleeve assembly having a side lock structure.

Known sleeve assemblies have a tube body and a sleeve, and there are a wide variety of fixed types. The most well-known fixed type is to fix the relative position of the sleeve and the tube body by the threaded member directly penetrating the tube wall of the sleeve and the tube body. When this is applied only to a thin tube main body and is used for a thin tube main body, loosening tends to occur between the sleeve and the pipe main body.

Currently, portable tables and chairs for camping, shelves for storerooms, and stands for photography are mainly light weighted. It seems that it is not suitable to operate the fixed type as it is. Since the known tube main body is thick, it can be fixed by inserting a general screwing member into the sleeve and the tube wall, but it becomes heavy and difficult to carry. When such a type is applied to a thin tube body, the contact area between the screwing member and the tube body is too small, so that loosening tends to occur.

In view of the above, an object of the present invention is to increase the contact area between the pipe body and the screwing member by the fitting portion thread formed between the screwing member and the pipe body, and to connect the pipe body and the sleeve. It is an object of the present invention to provide a side lock sleeve assembly that is not only loosely fixed but also tightly fixed.

A known sleeve assembly structure is one in which a sleeve and a tube body are penetrated by a screwing member, which is applicable only to a thick tube body, and when used in a thin tube body, Since the contact area of the tube body is too small, loosening tends to occur. In contrast, the present invention provides a structure of a side lock sleeve assembly, which has a first pipe and a sleeve wall, a part of which is a first coupling part, and the first coupling part is a first coupling part. An opening is provided at a predetermined location between the central portion of the first housing portion and the outer periphery of the sleeve wall in the first coupling portion, and the first pipe is connected to the first housing portion. A sleeve accommodated in one end and a side end as a penetration end, the other side end as an operation end, the diameter decreases from the operation end toward the penetration end, and the penetration end pivots into the opening. A screwing member that abuts between the sleeve and the first tube, and when the penetration end of the screwing member is swung into the opening, The screwing member is in contact with the first pipe, and a fitting thread that is blended with the surface shape of the screwing member is formed on the tube wall of the first pipe. Characterized in that it is made.

In the present invention, the sleeve is stably fixed at a predetermined position of the first pipe through such a structure, and sliding or rotation in the first pipe due to an external force is less likely to occur. Also, since another part of the sleeve of the present invention can be a second coupling part, there are two different preferred embodiments. In a first preferred embodiment, the second coupling part is a coupling base, and the coupling base can be coupled to a camera pan head, a photographing lamp, or photographing equipment. In addition, other operations are possible, for example, it is possible to operate on a connection base of photographing equipment at the top of a tripod.

In a second preferred embodiment, the second coupling part further has a second accommodating part, and the second pipe having a smaller diameter penetrates the second accommodating part and the first pipe, and The tube is slidable on the second housing portion and the first tube, and a fixing member is installed on the second joint portion. The fixing member includes the second tube, the second coupling portion, and the second tube. The relative position of the tube and the first tube can be fixed. Thereby, an expansion-contraction tube structure is formed and can be used for the middle expansion-contraction sleeve of a tripod.

The present invention further has a third preferred embodiment. In this embodiment, at least three lateral coupling portions are provided on the periphery of the sleeve, and at least one lateral support member is provided on each lateral coupling portion. Thereby, it can be used for the base of the middle tube of the tripod.

Finally, the present invention further has a fourth preferred embodiment. In this embodiment of the present invention, the sleeve has a plurality of first receiving portions, which can be assembled and operated as a shelf by combining them with a plurality of first tubes. In this embodiment, the sleeve has at least two first pipes, the sleeve has at least two first coupling portions, and a central portion of each first accommodating portion and each sleeve wall in each first coupling portion. Openings are provided at appropriate locations between the outer peripheries, and each first pipe is accommodated in each first accommodating portion, and at least two screwing members are respectively drilled while turning into the respective openings, The screwing members are in contact with the sleeves and the first tubes, respectively, and fitting screw threads are formed on the first tubes to be blended with the surface shape of the screwing members. A shelf can be assembled through a plurality of assemblies of the present invention, and furniture such as a table, a hanger, and a figurine shelf can be manufactured together with other types of parts.

In the side lock sleeve assembly provided by the present invention, the threaded member, the first pipe, and the first pipe are formed on the pipe wall of the first pipe, since the fitting part thread to be blended with the surface shape of the screwed member is formed. A larger contact fit area between the threaded member and the sleeve provides an improvement over known sleeve assemblies. As a result, the first pipe operated by the present invention is thinner, lighter and more robust and can be assembled quickly, and it is necessary to align the hole holes and screw in when assembling like a known sleeve assembly. Therefore, it is advantageous for mass production because the assembly work is saved.
