VI. Description of the invention: [Technical Field of the Invention] [0001] The present invention relates to a housing adjustment device. [Prior Art] [0002] Many electronic devices require an adjustment device capable of adjusting the height, and the adjustment device is generally disposed on a housing of the electronic device. For example, the cover of the projector generally has a foot for adjusting the height or For hanging screws. The projector's foot or screw is typically movably coupled to the cover by mating with a pre-formed nut within the cover. The pre-formed nut in the cover body is integrally formed with the cover body, and when the nut is slipped due to repeated use of the nut, it is difficult to replace the nut. [0003] In addition, the nut cannot be recycled and does not meet environmental protection requirements. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide a housing adjustment device that is easy to replace. [0005] A housing adjusting device having a first through hole. The housing adjustment device includes a nut, a screw, and a limiting device. The limiting device includes a plurality of side walls. The ends of the plurality of side walls are connected to each other by a bottom plate. The plurality of side walls and the bottom plate form a receiving space for receiving and defining the nut. The receiving space is in communication with the first through hole. The screw is screwed to the nut through the first through hole. The containment space has a notch having a lateral dimension greater than or equal to a maximum lateral dimension of the nut. A flexible baffle is disposed on each side of the notch, and the elastic brace is symmetrically disposed with respect to the notch. [0006] A housing adjusting device having a first through hole. The case 097132090 Form No. A0101 Page 3 of 13 1003297586-0 1351908 The next year, the shuttle is replaced by a nut and a screw. The adjustment device also includes a limiting device. The limiting device includes a plurality of side walls. The side wall encloses a receiving space having a notch. The receiving space is configured to receive and define the nut and communicate with the first through hole. The screw is screwed to the nut through the first through hole. At least one elastic baffle is disposed on opposite sides of the receiving space, and the end of the elastic brace extends a snap structure. [0007] The housing adjusting device of the present invention adds a limiting device to the housing, and the nut is added It is placed in the limiting device, and the height of the housing is adjusted by the cooperation with the screw. When the nut shows a slip phenomenon, the nut is directly taken out from the limiting device and replaced. [Embodiment] [0008] First Embodiment [0009] Please refer to circle 1 and FIG. 2 together, which is a housing adjustment device 100 according to a first embodiment of the present invention for adjusting the height of a casing 101 and a horizontal plane. . The housing 101 has a first through hole 102 therein. The housing adjustment device 100 includes a nut 10 , a screw 20 , and a limiting device 30 . The limiting device 30 has a receiving space 301 for receiving and defining the nut 10 , and the receiving space 301 and the first through hole 102 . Connected. The limiting device 30 is disposed on the inner side of the housing 101. The screw 20 is movably connected to the nut 10 through the first through hole 102 and partially received in the receiving space 301. [0010] In the embodiment, the housing 101 It is the outer casing of the projector. The size of the first through hole 102 is the same as the size of the screw 20. 097132090 Form No. Α0101 Page 4 of 13 1003297586-0 On August 17th, 100th, the shuttle replacement page 1.351908 [0011] In the present embodiment, the nut 10 is a common hex nut. [0012] The limiting device 30 is integrally formed with the housing 101. The limiting device 30 includes a plurality of side walls 31. The ends of the plurality of side walls 31 are connected to each other by a bottom plate 32. The plurality of side walls 31 and the bottom plate 32 form the receiving space 301. Specifically, each of the two adjacent side walls 31 forms an angle which is equal to the corner of the nut 10. When the nut 10 is received in the receiving space 301, the angle is matched with the corner of the nut 10 to limit The nut 10 rotates. In the present embodiment, the included angle is 120 degrees. The bottom plate 32 is for defining the nut 10 in the receiving space 301. A second through hole 321 is defined in the bottom plate 32. The second through hole 321 is opposite to the nut 10, and the diameter of the second through hole 321 is equal to the diameter of the screw 20. When the screw 20 is screwed into the nut 10, the screw 20 can also pass through the second through hole 321, so that the stroke of the screw 20 is not limited. In the embodiment, the second through hole 321 is a screw hole. The receiving space 301 has a notch 33 having a lateral dimension greater than or equal to the maximum lateral dimension of the nut 10. In this embodiment, at least one elastic baffle 34 is disposed on each side of the notch 33, and the elastic baffle 34 is symmetrically disposed with respect to the notch. When the nut 10 is pushed toward the notch 33, the elastic baffle 34 is elastically deformed, so that the nut 10 can be received in the receiving space 301; the elastic baffle 34 can maintain the external force without external force The nut 10 is stored in a state to prevent the nut 10 from coming off the receiving space 301. [0013] When the housing adjustment device 100 is used, the nut 10 is pushed into the accommodating space 301 from the notch 33. When the nut 10 is fixed, the screw 20 is screwed into the nut 10 from the outside of the housing 101 through the first through hole 102. By adjusting the length of the nut 20 screwed into the nut 10, the height of the housing 101 and the horizontal plane can be adjusted. 097132090 Form No. A0101 Page 5 of 13 1003297586-0 1351908 IDO is on the 17th of August. If the nut 10 has a slip wire, the nut 1 can be directly removed and replaced. [0014] Referring to FIG. 3, the clamshell adjusting device 200 according to the second embodiment of the present invention is different from the casing adjusting device 100 of the first embodiment in that the limiting device 230 of the present embodiment does not The bottom plate 32 is used, and at least one elastic baffle 234 is disposed on opposite sides of the accommodating space 2301. The end of the elastic brace 234 extends a snap structure 235, and the elastic brace 234 and the snap structure 235 The total length is equal to the longitudinal length of the nut 10. The snap structure 235 abuts against the surface of the nut 10 to define the nut 10 in the receiving space 2301. In the present embodiment, the snap structure 235 is formed in an inwardly extending barb shape. [0016] When the housing adjusting device 200 is used, the nut 10 is inserted into the receiving space 2301 from the notch 33, and then the screw 20 is screwed into the nut 10 from the outside of the housing 101. The nut 10 is clamped by the snap structure 235, and the nut 10 can be screwed to the screw 20 in a limited manner. When the nut 10 needs to be removed, the screw 2 is unscrewed and the nut 10 is removed from the notch 33 for the next use. [0017] The housing adjusting device of the present invention adds a limiting device to the housing, and places a nut in the limiting device, thereby adjusting the height of the housing by cooperating with the screw. When the nut shows a slip phenomenon, the nut is directly taken out from the limiting device and replaced. At the same time, because the nut can be recycled, it is more environmentally friendly. [0018] In summary, the present invention has indeed met the requirements of the invention patent, 遂 097132090 Form No. Α 0101 Page 6 / Total 13 pages 1003297586-0 Γ 351908 100 August 17, revised replacement page Patent application.
