[0017] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Before the present utility model is described in detail, it should be noted that similar elements are represented by the same reference numerals in the following description.

[0018] Please see Figures 1-6As shown, a preferred embodiment of this utility model discloses a quick-release fixture 10 for fixing a device under test (DUT) 130, applicable to a cabinet 200, comprising: a support plate 110, a front panel 120, the DUT 130, and a fixing fixture 140. Specifically, the support plate 110 is mounted on the cabinet 200, the front panel 120 is mounted on the cabinet 200 near the support plate 110, the DUT 130 is mounted on the support plate 110 near the front panel 120, and the fixing fixture 140 is mounted on the support plate 110, with the DUT 130 positioned between the front panel 120 and the fixing fixture 140. This application allows the DUT 130 to move closer to the front panel 120, and the fixing fixture 140 pushes against the DUT 130, thereby fixing the DUT 130 to the cabinet 200 and improving the quick-release efficiency of the DUT 130, but is not limited thereto.

[0019] In one embodiment of this utility model, two side plates 111 are provided on both sides of the support plate 110. The side plates 111 are provided with a plurality of positioning holes 113 and a plurality of positioning pins 114. The positioning pins 114 are installed in the positioning holes 113 and used to fix the support plate 110 to the cabinet 200. The front panel 120 is square and each corner is provided with a mounting hole 121. The mounting holes 121 are for the positioning pins 114 to be installed, so as to fix the front panel 120 to the cabinet 200. In this way, with the cooperation of the positioning holes 113 and the positioning pins 114, and the mounting holes 121 and the positioning pins 114, the support plate 110 and the front panel 120 are mounted on the cabinet 200. The fixing fixture 140 is provided with a stop member 141 and two stop parts 142. The stop member 141 is used to stop the middle of the rear side of the device under test 130, and the stop parts 142 are used to stop the two ends of the rear side of the device under test 130. With the stopper 141 and stopper 142 configured, the fixing fixture 140 slowly pushes against the rear side of the device under test 130, so that the device under test 130 moves closer to the front panel 120. It should be noted that the surface of the support plate 110 is provided with a plurality of through holes 112, and the bottom of the fixing fixture 140 is provided with a plurality of protrusions 143. By installing the protrusions 143 into the through holes 112, the fixing fixture 140 is fixed to the support plate 110.

[0020] In detail, firstly, the support plate 110 is fixed to the cabinet 200 with the cooperation of the positioning pin 114 and the positioning hole 113. Of course, this application does not limit the fixing of the support plate 110 to the cabinet 200 to only using the positioning pin 114 and the positioning hole 113; it can be changed according to different cabinets 200 and the support plate 110, but is not limited thereto. Secondly, the front panel 120 is fixed to the cabinet 200 with the cooperation of the positioning pin 114 and the mounting hole 121, and the front panel 120 is positioned close to the support plate 110. Of course, this application does not limit the fixing of the front panel 120 to the cabinet 200 to only using the positioning pin 114 and the mounting hole 121; it can be changed according to different cabinets 200 and the front panel 120, but is not limited thereto. Thirdly, the device under test 130 is placed close to the front panel 120 and mounted on the support plate 110. Finally, with the stopper 141 of the fixing fixture 140 stopping the middle of the rear side of the device under test 130, and the stopper 142 of the fixing fixture 140 stopping the two ends of the rear side of the device under test 130, the fixing fixture 140 pushes the device under test 130 closer to the front panel 120, thereby positioning the device under test 130 between the front panel 120 and the fixing fixture 140, thus fixing the front and rear sides of the device under test 130. At the same time, when the fixing fixture 140 slowly pushes the device under test 130, one side of the fixing fixture 140 abuts against the side plate 111, and the other side of the fixing fixture 140 abuts against the device under test 130, serving as a stopper to fix the left and right sides of the device under test 130. Through the above-described configuration, the device under test 130 can be quickly installed or removed from the cabinet 200. This effectively solves the problem of using screws to fix the device under test 130. Furthermore, it allows for the replacement of the appropriate fixing fixture 140 depending on the device under test 130 and the cabinet 200, avoiding the need for time-consuming and laborious screw removal, which consumes a lot of manpower and resources. This effectively solves the shortcomings of the prior art and significantly improves the efficiency of quick removal.

[0021] By the way, Figure 5This is a cross-sectional view of the quick-release fixture 10 from one angle. The diagram shows that the protrusion 143 is installed on the through hole 112 to fix the fixing fixture 140 to the support plate 110. The diagram also shows that the abutment 141 is located in the middle of the rear side of the device under test 130, and the abutment portions 142 are located at both ends of the rear side of the device under test 130. One side of the fixing fixture 140 abuts against the side plate 111, and the other side abuts against the device under test 130. In other words, the diagram shows that the abutment portion 142 on one side of the fixing fixture 140 is close to the rear end of one side of the device under test 130, and the abutment portion 142 on the other side of the fixing fixture 140 is close to the rear end of the other side of the device under test 130. Furthermore, the fixing fixture 140 is slightly higher than the side wall of the side plate 111. Therefore, the fixing fixture 140 can fix the device under test 130 on all four sides (front, back, left, and right).

[0022] By the way, Figure 6 This is a cross-sectional view of the quick-release fixture 10 along line FF. The view shows that the stop 141 is close to the rear side of the device under test 130, and in conjunction with... Figure 5 The device under test (DUT) 130 is brought close to the front panel 120, and is pushed against the DUT 130 by the fixing fixture 140, thereby fixing the front and rear sides of the DUT 130. It should be noted that, since the fixing fixture 140 is designed to take into account the tolerance of actual production, if the fixing fixture 140 is completely flush with the DUT 130, it may cause problems with actual assembly. Therefore, there will be a small gap between the fixing fixture 140 and the DUT 130 to solve the above-mentioned tolerance problem. Of course, these gaps will be filled with foam to prevent the device from shaking and thus play a role in fixing it, but this is not the only limitation.

[0023] Furthermore, one side of the fixing fixture 140 abuts against the side plate 111, and the other side of the fixing fixture 140 abuts against the device under test 130. The fixing fixture 140 is configured to provide resistance, thereby fixing the left and right sides of the device under test 130. Please refer to [link / reference]. Figure 2 and Figure 5To allow the fixture 140 to push the device under test 130 against the front panel 120, the fixture 140 is inserted between the side plate 111 and the device under test 130, such that one side of the fixture 140 is positioned between the side plate 111 and the device under test 130, and the fixture 140 is slightly higher than the side wall of the side plate 111 to provide a blocking effect. Similarly, the other side of the fixture 140 is similar to the first side, so it will not be described in detail here. Through the above operation, the fixture 140 can be positioned so that one side of the fixture 140 abuts against the side wall of the side plate 111, and the other side of the fixture 140 abuts against the device under test 130, thereby fixing both sides of the fixture 140, but this is not a limitation.

[0024] Furthermore, the fixture 140 is made of photosensitive resin. It should be noted that photosensitive resin is characterized by rapid curing and precise processing. In addition, fixtures 140 with different features can be rapidly manufactured using 3D printing technology to meet the needs of fixing different models of the device under test 130 in different models of cabinets 200, but this is not a limitation.

[0025] Furthermore, the fixing fixture 140 is arranged in an E-shape. See also... Figure 2 , Figure 4 and Figure 5 It should be noted that the shape of the fixing fixture 140 is not particularly limited and can be changed according to actual needs, but is not limited thereto. The shape of the fixing fixture 140 is only to be able to push the device under test 130 so that the device under test 130 can be fixed to the support plate 110 through the fixing fixture 140. In other words, different shapes of fixing fixtures 140 can be used depending on the different devices under test 130 to achieve the purpose of pushing or fixing.

[0026] Additionally, the retaining member 141, retaining part 142, protrusion 143, dimensions, and plate thickness of the fixing fixture 140 are all integrally molded. Specifically, the integral molding method of producing the fixing fixture 140 makes it suitable for mass production, effectively improving production efficiency. Furthermore, specific details can be modified according to different situations of the device under test 130 to meet different production needs, but this is not a limitation.

[0027] In summary, the quick-release fixture 10 of this utility model, through the cooperation of the blocking member 141 of the fixing fixture 140 blocking the middle of the rear side of the device under test 130, and the blocking part 142 of the fixing fixture 140 blocking the two ends of the rear side of the device under test 130, allows the device under test 130 to be brought close to the front panel 120, and the fixing fixture 140 to push against the device under test 130, thereby fixing the front and rear sides of the device under test 130. One side of the fixing fixture 140 abuts against the side plate 111, and the other side of the fixing fixture 140 abuts against the device under test 130, thereby fixing the left and right sides of the device under test 130. This achieves the purpose of fixing the device under test 130 through this application, improving disassembly efficiency, making it convenient to use, and providing excellent practicality. Furthermore, other objectives and advantages of this utility model can be further understood from the technical features disclosed in this utility model.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
