Detailed Implementation
[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0030] Example 1
[0031] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a differential mode ripple injection detection device, which includes a detection component 100 and a side plate mechanism 200. The detection component 100 can be used to evaluate the electronic equipment's tolerance to differential mode ripple interference. The side plate mechanism 200 facilitates the disassembly and assembly of the side plate, making it convenient for internal maintenance. Disassembly does not require tools, and a complete side plate is divided into multiple parts, reducing the weight of each installation.
[0032] Specifically, the testing component 100 includes a housing 101, in which a testing machine 102 is placed. The testing machine 102 is a differential mode ripple injection tester, which is existing technology. The working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here. The housing 101 has a groove 103 and a positioning groove 104. The groove 103 provides a position for the installation of the fixing component 105. The positioning groove 104 is used to insert the card plate 204 to limit and fix the mesh plate 201. The fixing component 105 is installed in the groove 103. The fixing component 105 can limit and fix the testing machine 102 inserted into the housing 101, and can also be unlocked.
[0033] Specifically, the side plate mechanism 200 is installed on the surface of the housing 101 and located on both sides, including a mesh plate 201. The mesh plate 201 is movably connected to the surface of the housing 101. There are three mesh plates 201 on each side of the housing 101. The corresponding mesh plate 201 can be removed according to the area to be inspected, and the corresponding testing machine 102 can be released at the same time, which facilitates the operator to carry out maintenance. The inner cavity of the mesh plate 201 is rotatably connected to a round shell 202, which provides a position for the installation of the adjusting component 203. When it rotates, it can drive the adjusting component 203 to rotate.
[0034] An adjusting component 203 is installed at one end of the round shell 202. A retaining plate 204 is slidably connected to the inner cavity of the mesh plate 201. One corresponding retaining plate 204 extends through the box body 101 to the surface of the fixing component 105, and the other corresponding retaining plate 204 extends through the mesh plate 201 to the inner cavity of the positioning groove 104. By inserting the retaining plate 204 into the groove 103 and the positioning groove 104, the mesh plate 201 can be fixed in the box body 101. When one retaining plate 204 is inserted into the groove 103 and squeezes the limiting block 105a, the limiting block 105a moves out of the box body 101, thereby limiting and fixing the testing machine 102 inserted into the box body 101.
[0035] Example 2
[0036] Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0037] Specifically, the fixing component 105 includes a limiting block 105a, the surface of which is provided with an inclined surface. One end of the clamping plate 204 is chamfered. The limiting block 105a is slidably connected in the groove 103, and one end extends through the box 101 to the surface of the testing machine 102. The chamfer of the clamping plate 204 moves and presses the inclined surface of the limiting block 105a, which facilitates the movement of the limiting block 105a. This allows one end of the limiting block 105a to be moved out of the box 101, thereby limiting the testing machine 102 inserted into the box 101.
[0038] The inner wall of the groove 103 is provided with a guide groove 105b, and a guide block 105c is slidably connected in the guide groove 105b. The guide block 105c is fixedly connected to the surface of the limiting block 105a. The guide groove 105b and the guide block 105c guide and limit the limiting block 105a, so that the limiting block 105a can only move along its guiding direction. A second spring 105d is fixedly connected to the surface of the guide block 105c. The second spring 105d moves on the clamping plate 204. As the device continuously detaches from the limiting block 105a, its retraction causes the limiting block 105a to move into the groove 103, releasing the limiting fixation on the testing machine 102. This indicates that the testing machine 102 at the corresponding position needs to be pulled out for maintenance, or the card plate 204 needs to be moved. The screen plate 201 needs to be unlocked, the screen plate 201 needs to be removed, and the corresponding part located in the box 101 needs to be maintained. One end of the second spring 105d is fixedly connected to the inner wall of the guide groove 105b.
[0039] The side plate mechanism 200 also includes a roller 205, which is fixedly connected to one end of the clamping plate 204. The roller 205 reduces the resistance when the adjusting member 203 drives the clamping plate 204, so that when the adjusting member 203 rotates, the roller 205 and the clamping plate 204 can move smoothly to the corresponding position. A short block 206 is fixedly connected to the surface of the clamping plate 204, and a first spring 207 is fixedly connected to the surface of the short block 206. The short block 206 and the first spring 207 provide the clamping plate 204 with the power to move towards the adjusting member 203. After the adjusting member 203 is rotated and adjusted, the roller 205 is located in the recess on the adjusting member 203. One end of the first spring 207 is fixedly connected to the inner wall of the mesh plate 201.
[0040] A driving component 208 is installed on the surface of the round shell 202. The driving component 208 drives the round shell 202, thereby driving the adjusting component 203 and moving the clamping plate 204 to the corresponding position. A slot 209 is provided on one side of the mesh plate 201. The slot 209 limits the rotation of the driving component 208 to prevent the mesh plate 201 from being opened and removed without human intervention. The slot 209 cooperates with the driving component 208.
[0041] A mating block 210 is fixedly connected to the surface of the mesh plate 201 and is located on both sides of the mesh plate 201. A mating groove that mates with the mating block 210 is opened on the surface of the box body 101. Through the mating block 210 and the mating groove, the mesh plate 201 can be initially mated to the box body 101, so that the card plate 204 can be accurately inserted into the groove 103 and the positioning groove 104, thereby fixing the mesh plate 201 to the box body 101.
[0042] The adjusting component 203 includes a turntable 203a, which is sleeved on one end surface of the circular shell 202. The surface of the turntable 203a is respectively provided with a first limiting groove 203b, a second limiting groove 203c and a third limiting groove 203d. The surface of the roller 205 is in contact with the surface of the turntable 203a. When the roller 205 is located in the first limiting groove 203b, a clamping plate 204 makes close contact with the limiting block 105a, causing it to be squeezed and causing the limiting block 105a to move out of the housing 101 to limit and fix the testing machine 102. One end of the other clamping plate 204 is still inserted into the positioning groove 104.
[0043] When the roller 205 is in the second limiting groove 203c, the clamping plate 204 moves towards the turntable 203a under the action of the first spring 207 and the short block 206. One clamping plate 204 is released from the pressure of the limiting block 105a, and the limiting block 105a moves back under the action of the second spring 105d, losing its limiting position on the inspection machine 102 and being released from fixation. One end of the other clamping plate 204 is half-filled with the positioning groove 104. When the roller 205 is in the third limiting groove 203d, both clamping plates 204 are released from the limiting position of the box 101 at the same time, so that the mesh plate 201 can be removed from the box 101.
[0044] The driving component 208 includes a square post 208a, which is slidably connected to the surface of the circular shell 202. The square post 208a is limited by a block 208b to prevent it from detaching from the circular shell 202 when the square post 208a is pulled. One end of the square post 208a extends into the inner cavity of the circular shell 202 and is fixedly connected to the block 208b. The square post 208a can move on the circular shell 202. When it rotates, it can drive the circular shell 202 to rotate, which in turn drives the turntable 203a to rotate, squeezing and moving the roller 205, and then springing back to move into the corresponding limiting groove.
[0045] A handle 208c is fixedly connected to the end of the square column 208a away from the square block 208b. By pulling the handle 208c, the square column 208a can be moved easily. A locking post 208d is fixedly connected to the surface of the handle 208c. The locking post 208d is inserted into the locking slot 209. By inserting the locking post 208d into the locking slot 209, the handle 208c, the square column 208a and the round shell 202 are limited, thereby limiting and fixing the turntable 203a after rotation adjustment.
[0046] A third spring 208e is fitted on the surface of the square column 208a. Under the action of the elastic force of the third spring 208e, the locking column 208d is inserted into the locking slot 209 and will not be dislodged from the locking slot 209 without human intervention. When dislodging, the corresponding elastic force needs to be overcome to improve the safety of use. The two ends of the third spring 208e are fixedly connected to the inner wall of the round shell 202 and the surface of the square block 208b, respectively.
[0047] When in use, when it is necessary to pull out the corresponding testing machine 102 from the front of the device for maintenance, hold the handle 208c on the corresponding mesh plate 201 and pull it to make the locking post 208d disengage from the locking groove 209, so that the square post 208a and the block 208b move and the third spring 208e is compressed. Then, turn the handle 208c to drive the square post 208a, the block 208b, the round shell 202 and the turntable 203a to rotate, so that the roller 205 is squeezed and disengaged from the first limiting groove 203b, and rotated to the second limiting groove 203c and aligned with the roller 205.
[0048] Under the action of the first spring 207, the short block 206 and the clamping plate 204 move, and the roller 205 moves into the second limiting groove 203c. The limiting block 105a gradually loses the effect of the clamping plate 204. Under the action of the second spring 105d, the limiting block 105a is reset and moves into the groove 103 to break away from the limiting and fixing of the testing machine 102. Then, the clamping post 208d is inserted into the corresponding clamping groove 209, so that the testing machine 102 can be pulled out of the box 101.
[0049] When it is necessary to remove the mesh plate 201 from the housing 101 for maintenance, continue to rotate the turntable 203a so that the roller 205 is in the third limiting groove 203d. At this time, the clamping plate 204 is released from the restriction of the housing 101, and the mesh plate 201 can be removed from the housing 101. The corresponding mesh plate 201 can be disassembled as needed, or all of them can be removed. It is not necessary to disassemble a complete and heavy side plate at once, while reducing the space occupied.
[0050] In summary, the fastener 105, under the action of the clamping plate 204, can easily limit and fix the detector on the cabinet. Compared with the prior art, it does not require bolts for installation, making it very convenient for maintenance and disassembly. The side plate mechanism 200 facilitates the disassembly and assembly of the side plate, making it convenient for internal maintenance. Compared with the prior art, it does not require tools for disassembly. At the same time, dividing a complete side plate into multiple parts reduces the weight of a single installation. Disassembly and assembly can be completed by a single person, which is very convenient.
[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
