[0014] Please also refer to figure 1 and figure 2 , is the fixing device 100 according to the first embodiment of the present invention, which includes a nut 10 having a threaded through hole 17 and a base plate 20 , and the nut 10 is accommodated in the base plate 20 .

[0015] The base plate 20 includes a body part 22 , two clamping parts 24 and a limiting part 26 . The body portion 22 is provided with a through hole 220 passing through the body portion 22 , and the through hole 220 corresponds to the threaded through hole 17 of the nut 10 . The main body 22 can be a casing of an electronic device, such as a projector or a TV casing, or the main body 22 can be separately formed on the casing of an electronic device. The two clamping elements 24 are vertically disposed on the body portion 22 and symmetrically distributed around the through hole 220 . The two clamping parts 24 are elastic structures, and each clamping part 24 includes a supporting part 240 and an engaging ...

no. 2 approach

[0022] see Figure 4 , is a schematic cross-sectional view of the fixing device 200 according to the second embodiment of the present invention. The difference from the first embodiment is that the limiting part 260 is a circular counterbore opened on the body part 222, and the limiting part 260 The position portion 260 and the clamping member 240 form a receiving space 280 . The shape of the limiting portion 260 is not limited to the circular shape in this embodiment, and may also be a hexagonal shape, as long as it is consistent with the shape of the nut 102 to ensure that the nut 102 is tightly accommodated in the receiving space 280 .

[0023] It can be understood that the limiting portion can be combined with the baffle in the first embodiment and the counterbore in the second embodiment, so that the receiving space formed by the limiting portion and the clamping member can accommodate the nut more tightly.

[0024] In the embodiment of the present invention, the fixing ...

Abstract

The present invention relates to a fixing device including at least one nut with thread through hole and a base plate, wherein at least two guide way evenly distributed on the outer surface of the nut; a noumenon part, at least two clamping parts and a limiting part set base plate; a through hole penetrating the noumenon part which is corresponding to the thread through hole set on the noumenon part; each clamping part set on the noumenon vertically and scarred around the through hole; the limiting part positioned in noumenon part; the clamping part and limiting part form a collecting space to collect the nut; the collecting space connects with the through hole; the clamping part coordinates with the nut guideway to clamp nut collected in collecting space; the fixing device collects nut through collecting space formed by clamping part and limiting part, and clamps the nut with clamping part. Assembling is simple and production efficiency of electronic device thereafter.

Description

technical field [0001] The invention relates to a fixing device, in particular to a fixing device for hanging electronic devices. Background technique [0002] With the vigorous development of science and technology, the application of electronic devices is becoming more and more extensive. For example, projectors currently have four projection modes: front projection, rear projection, ceiling projection and ceiling rear projection, depending on the actual use environment. Among them, the ceiling projection and ceiling rear projection projectors need to have specific fixing devices to fix the projector and the boom, so as to realize the ceiling projection and ceiling rear projection functions of the projector. Another example is that television sets in public places are usually hung on high places for the convenience of viewers to watch. The TV set is also required to have a specific fixing device if it is hung in a high place. In addition, electronic devices such as camer...
