Description

Technical Field

[0001] This utility model relates to the field of EMS testing equipment technology, and in particular to a multifunctional control cabinet and EMS testing system. Background Technology

[0002] Multifunctional control cabinets have a variety of functions and complex parameter settings, which makes installation and commissioning relatively complicated. They often require professional technicians to operate them to ensure correct installation and normal operation.

The second groove element 61 is disposed in the middle of the corresponding first sliding unit 20 and connected to it. The second limiting element 62 is movably disposed inside the first sliding unit 20 and is slidably connected to the second groove element 61 and limitedly connected to the second sliding unit 30, thereby limiting the displacement range of the second sliding unit 30. The second elastic element 63 is disposed between the second groove element 61 and the second limiting element 62.

[0153] Specifically, the second groove element 61 is disposed in the middle of the first sliding element 21 and communicates with the second connecting element 23 and is connected to the first sliding element 21; the second limiting element 62 is movably disposed inside the first sliding element 21 and is limitedly connected to the second sliding element 31.

[0154] More specifically, the second groove element 61 is disposed in the middle of the side plate; the second limiting element 62 is movably disposed between the two side plates.

[0155] In some embodiments, the connection between the second groove element 61 and the first sliding element 21 includes, but is not limited to, welding and screw connection.

[0156] The dimensions of the second slot element 61 are matched with the dimensions of the second connecting element 23. Generally, the radial dimension (e.g., width, height) of the inner contour of the second slot element 61 is not less than the radial dimension (e.g., width, height) of the second connecting element 23.

[0157] In some embodiments, the second groove element 61 has a U-shaped cross-section. Specifically, the open end of the second groove element 61 is located on the outside of the side plate and surrounds the second connecting element 23.

[0158] In some of these embodiments, the second slot element 61 is a receiving slot.

[0159] The dimensions of the second limiting element 62 are matched with the dimensions of the second connecting element 23. Generally, the radial dimension (e.g., height, length) of the second limiting element 62 is not greater than the radial dimension (e.g., height, length) of the second connecting element 23.

[0160] The dimensions of the second limiting element 62 are matched with the dimensions of the second slot element 61. Generally, the radial dimension (e.g., height, length) of the second limiting element 62 is smaller than the radial dimension (e.g., height, length) of the second slot element 61, and the width of the second limiting element 62 is smaller than the depth of the second slot element 61.

[0161] The dimensions of the second limiting element 62 are matched with the dimensions of the first sliding element 21. Generally, the width of the second limiting element 62 is less than 1 / 2 of the radial dimension (such as width) of the base plate.

[0162] In some embodiments, the cross-section of the second limiting element 62 is an isosceles obtuse triangle. Specifically, the obtuse angle of the second limiting element 62 is disposed towards the inside of the first sliding element 21, and the base of the second limiting element 62 is disposed towards the second groove element 61.

[0163] In some of these embodiments, the second limiting element 62 is a second locking block.

[0164] In some embodiments, the connection between the first elastic element 53 and the second limiting element 62 and the second groove element 61 is including but not limited to welding.

[0165] The dimensions of the first elastic element 53 are matched with the dimensions of the second groove element 61. Generally, in its natural state, the length of the first elastic element 53 is equal to the depth of the second groove element 61; in its maximum compressed state, the sum of the length of the first elastic element 53 and the width of the second limiting element 62 is not greater than the depth of the second groove element 61.

[0166] In some of these embodiments, the first elastic element 53 includes, but is not limited to, a spring.

[0167] The method of using this utility model is as follows:

[0168] The advantage of this utility model is that by setting an opening unit that can slide along the cabinet unit after opening, the opening unit can be prevented from closing when the staff operates the equipment in the cabinet unit. At the same time, it expands the staff's operating space, improves work efficiency, and solves the problems of existing multi-functional control cabinets where the opening fan cannot be fixed after opening and the staff's operating space is limited.

[0169] Example 2

[0170] This embodiment is a supplementary embodiment to Embodiment 1.

[0171] like Figure 8 As shown, the multi-functional control cabinet also includes several heat dissipation units 70. These heat dissipation units 70 are respectively disposed in corresponding opening units 40 and are used to dissipate heat from the cabinet unit 10.

[0172] Specifically, several heat dissipation units 70 are respectively disposed on the corresponding opening element 41.

[0173] The number of heat dissipation units 70 matches the number of opening units 40. Generally, the number of heat dissipation units 70 is equal to the number of opening units 40, that is, there is a one-to-one correspondence between heat dissipation units 70 and opening units 40.

[0174] In some embodiments, the heat dissipation unit 70 includes, but is not limited to, a perforated heat sink and heat dissipation louvers.

[0175] The advantage of this embodiment is that by setting a heat dissipation unit in the opening unit, the heat dissipation performance of the multi-functional control cabinet is enhanced, and the service life of the EMS testing device is extended.

[0177] This embodiment relates to the EMS testing system of this utility model.

[0178] An EMS testing system includes a multi-functional control cabinet as described in Embodiments 1 and 2, and an EMS testing device. The EMS testing device is located inside the enclosure unit 10 of the multi-functional control cabinet.

[0179] Specifically, the EMS testing device is located inside the support element 11.

[0180] In some embodiments, the connection between the EMS testing device and the support element 11 includes, but is not limited to, screw connections.

[0181] In some embodiments, the EMS testing apparatus includes a rotatable display screen, a UPS, a battery pack, an air switch, a power control system, a coordination controller, a protocol conversion device, a TAOKE collector, a protocol converter, and a monitoring workstation.

[0182] The advantages of this utility model are basically the same as those of Embodiment 1, and will not be repeated here.

[0183] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
