Problems solved by technology

The screw holes 121 on the housing of the projector 12 are generally formed by heat-melting or injecting and embedding studs with internal threads, and the studs cannot be disassembled and recycled after being assembled into the housing, resulting in a decrease in the product recovery rate. And it is impossible to classify plastic shells and metal studs

Embodiment Construction

[0013] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0014] See also Figure 2A and Figure 2B , Figure 2A It is a top view of the stud structure of an embodiment of the present invention, Figure 2B It is an A-A sectional view of a stud structure according to an embodiment of the present invention. The stud structure 2 includes a hollow bolt body 21 , an adjustment portion 22 and a blocking piece 23 . The bolt body 21 is provided with a first threaded portion 211 outside, and the bolt body 21 is provided with a second threaded portion 212 inside, and the first threaded portion 211 and the second threaded portion 212 have different helical directions. The different rotation direction of the thread is to consider the use characteristics of the wall mount for the projector, and design the different rotation direction...

Abstract

The invention provides a stud structure and a projector applying the same. The stud structure comprises a hollow bolt body, an adjusting part and a separation blade, wherein a first thread part is arranged outside the stud body; a second thread part is arranged inside the stud body; and the thread screwing direction of the first thread part is different from that of the second thread part. The adjusting part is arranged at one end of the bolt body; and the adjusting part is used for being matched with a detaching tool when the stud structure is detached. The separation blade is arranged between the adjusting part and the bolt body; and the cross sectional area of the separation blade is greater than that of the bolt body. According to the invention, the stud structure can be conveniently detached from an electronic product casing and recovering. In addition, with the design of the separation blade and the adjusting part at one end of the bolt body, the phenomenon that internal elements of the projector are damaged because a user uses an overlong screw to lock and attach to the projector can be avoided.

Description

technical field [0001] The present invention relates to a stud structure and a projector using the same, in particular to a stud structure that is easy to disassemble and recycle and a projector using the same. Background technique [0002] During the use of the projector, it is often necessary to install the projector on a wall mount. See figure 1 In the prior art, a plurality of screws 11 are used to lock the corresponding screw holes 121 on the casing of the projector 12 to fix the projector 12 and the wall mount 13 . The screw holes 121 on the housing of the projector 12 are generally formed by heat-melting or injecting and embedding studs with internal threads, and the studs cannot be disassembled and recycled after being assembled into the housing, resulting in a decrease in the product recovery rate. And it is impossible to classify plastic shells and metal studs. At present, many certification systems or industry standards for electronic products require the produ...
