Wherein, blocking sections 60 can be arranged near the first and second mounting holes 54, 58. The blocking section 60 can be a part of the arm portion 50, or the blocking section 60 can be a component arranged on the arm portion 50, the present invention is not limited thereto. Moreover, each of the first and second mounting holes 54, 58 can comprise a first hole portion 62 and a second hole portion 64. The second hole portion 64 is smaller (or narrower) than the first hole portion 62, and communicated with the first hole portion 62. The blocking section 60 can be arranged near the second hole portion 64.
The cable management device 38 can be detachably mounted to the first cable management arm 34. The cable management device 38 comprises abase 66, a first mounting portion 68 and an elastic portion 70, and preferably further comprises a second mounting portion 72. The first mounting portion 68 and the second mounting portion 72 respectively correspond to the first mounting hole 54 and the second mounting hole 58 of the arm portion 50 of the first cable management arm 34. On the other hand, the elastic portion 70 corresponds to the positioning hole 56 of the arm portion 50. Specifically, the first mounting portion 68 and the second mounting portion 72 are connected to the base 66, and each of the first mounting portion 68 and the second mounting portion 72 can comprise a first protruding section 74 and a second protruding section 76 substantially connected to the first protruding section 74 perpendicularly. The elastic portion 70 is arranged on the base 66. Preferably, the elastic portion 70 can be made of a flexible material and comprise a first section 78a and a second section 78b corresponding to the first section 78a. The first section 78a is connected to the base 66, and a clasp arm 80 is arranged adjacent to the first section 78a. In addition, a space 82 (or a notch) is defined on the base 66 of the cable management device 38, and the second section 78b of the elastic portion 70 corresponds to the space 82.
As shown in FIG. 4 and FIG. 5, during a mounting process, the first mounting portion 68 and the second mounting portion 72 of the cable management device 38 can be respectively aligned to the first mounting hole 54 and the second mounting hole 58 of the arm portion 50 of the first cable management arm 34, so that the first protruding sections 74 of the first mounting portion 68 and the second mounting portion 72 can enter the first mounting hole 54 and the second mounting hole 58 respectively. On the other hand, the first section 78a and the clasp arm 80 of the elastic portion 70 of the cable management device 38 are capable of entering the positioning hole 56 of the arm portion 50. When the first section 78a and the clasp arm 80 enter the positioning hole 56 of the arm portion 50, the second section 78b of the elastic portion 70 of the cable management device 38 is pressed by the arm portion 50, and the second section 78b temporarily enters the space 82 of the base 66 of the cable management device 38, so that the elastic portion 70 can accumulate an elastic force.
Please refer to FIG. 5 and FIG. 6. The cable management device 38 can be further moved toward a first direction D1. During this process, the first protruding sections 74 of the first mounting portion 68 and the second mounting portion 72 enter the second hole portions 64 from the first hole portions 62 of the first mounting hole 54 and the second mounting hole 58 respectively. Please also refer to FIG. 7. The second protruding sections 76 of the first mounting portion 68 and the second mounting portion 72 are blocked by corresponding blocking sections 60. On the other hand, the elastic portion 70 of the cable management device 38, such as the second section 78b of the elastic portion 70 releases the accumulated elastic force and enters the positioning hole 56 of the arm portion 50, and the elastic portion 70 is blocked by at least one blocking wall of the arm portion 50 of the first cable management arm 34. For example, the first section 78a and the second section 78b of the elastic portion 70 can be blocked by a first blocking wall 84a and a second blocking wall 84b of the arm portion 50 respectively. In addition, the clasp arm 80 arranged on the first section 78a of the elastic portion 70 can clasp with the arm portion 50 of the first cable management arm 34, in order to enhance reliability of mounting the cable management device 38 to the cable management arm. More particularly, because the first mounting hole 54 and the second mounting hole 58 are arranged at two corresponding positions on the arm portion 50 of the first cable management arm 34 (or the second cable management arm 36), when the first mounting portion 68 and the second mounting portion 72 are respectively mounted to the first mounting hole 54 and the second mounting hole 58, stability of mounting the cable management device 38 to the cable management arm is further enhanced.
As shown in FIG. 8, when detaching the cable management device 38 from the first cable management arm 34 (or the second cable management arm 36), the elastic portion 70 can be operated (for example, pressing one part of the second section 78b of the elastic portion 70) to avoid being blocked by the second blocking wall 84b of the arm portion 50 of the first cable management arm 34. Therefore, the cable management device 38 can be moved toward a second direction D2 opposite to the first direction D1, such that the second protruding sections 76 of the first mounting portion 68 and the second mounting portion 72 of the cable management device 38 is capable of moving apart from the blocking section 60 toward the second direction D2 and leave the second hole portion 64. Thus the first mounting portion 68 and the second mounting portion 72 can be detached from the first mounting hole 54 and the second mounting hole 58. Therefore, the cable management device 38 can be rapidly mounted to or detached from the cable management arm, so as to increase installation efficiency for operators.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
