Description
TECHNICAL FIELD
[0001] The utility model relates to a carrying device technical field, especially a type changing device. BACKGROUND
[0002] Products need to be tested in different ways during production to ensure product quality. Different testing equipment with different functions, sizes and shapes is needed during different testing processes. Because the testing equipment is usually heavy and relatively large in size, at least two operators are usually needed to manually carry it, which not only wastes human resources but also is inefficient. At the same time, the operators are likely to be injured or the clamps are likely to be damaged during the carrying process, which is a high safety risk.
[0003] Therefore, there is an urgent need for a type changing device that can solve the above problems. If the type changing device is to be used for testing equipment in different testing processes, it needs to have an adjustable function. However, because some testing equipment is heavy, the type changing device with an adjustable function may fail due to the weight of the testing equipment, and there is no need to adjust the testing equipment for different testing processes. SUMMARY
[0004] The utility model aims at solving the technical problems of high labor cost of the carrying method of the existing testing equipment and easy failure of the ordinary type changing device due to the gravity of the testing equipment. The utility model provides a type changing device that can save labor cost, be suitable for testing equipment of different sizes, be efficient and not easily affected by the testing equipment.
[0005] To solve the above technical problems, an embodiment of the utility model discloses a type changing device, which comprises:
[0006] a main body part;
[0007] a first sliding part connected to the main body part in a slidable manner along a first direction;
[0008] an adjusting part comprising a second sliding part, a third sliding part and at least two first guide rails, the at least two first guide rails being arranged at intervals along the first direction, and the at least two first guide rails extending along a second direction and being connected to the first sliding part, the second sliding part and the third sliding part being connected to the at least two first guide rails in a slidable manner along the second direction;
[0009] The telescopic part includes a first telescopic component and a second telescopic component, the first telescopic component and the second telescopic component respectively extend along a third direction, the first telescopic component is connected with the second sliding part, and the second telescopic component is connected with the third sliding part; the first telescopic component and the second telescopic component are respectively used for telescoping along the third direction, and the first telescopic component and the second telescopic component are used for collectively clamping an external device.
[0010] The first direction, the second direction and the third direction are perpendicular to each other.
[0011] By using the technical scheme, the model changing device can be applied to model changing transportation of different test devices in printed circuit board assembly (PCBA). That is, the model changing device can be adjusted in the first direction (for example, the height direction), the second direction (for example, the length direction) and the third direction (for example, the width direction), so as to adapt to test devices of different sizes and shapes. For example, the sizes and shapes of test devices used in different test processes such as in-circuit test (ICT), flash programming and function circuit test (FCT) are different. When the printed circuit board assembly is tested one by one, different test devices need to be replaced, and the heights, lengths and widths of various test devices are different. Since the model changing device can be adjusted in the above three directions, it can be compatible with all test device model changes.
[0012] Specifically, the adjusting part and the telescopic part can simultaneously move relative to the main part through the first sliding part, so as to realize adjustment in the first direction. The telescopic part includes two telescopic components (that is, the first telescopic component and the second telescopic component), the two telescopic components are used for collectively clamping an external test device, and the first telescopic component and the second telescopic component can respectively telescope along the third direction. Therefore, the first telescopic component and the second telescopic component can adapt to test devices of different depths (that is, lengths along the third direction).
[0013] At the same time, the first telescopic component and the second telescopic component are respectively connected with the second sliding part and the third sliding part in the adjusting part, and the second sliding part and the third sliding part can slide along the second direction, so as to adapt to test devices of different widths (that is, lengths along the second direction).
[0014] Therefore, the model changing device does not need to be manually carried by multiple operators, and only needs to be operated by one operator, so that human resource waste, test device damage, operator injury and other adverse conditions can be avoided, and the time for replacing test devices can be saved, and the efficiency is high.
[0015] On the other hand, due to the weight of part of the test equipment, if the ordinary adjusting part (i.e. the ordinary sliding part and the guide rail) is used, and the test equipment is clamped by the first telescopic assembly and the second telescopic assembly, the sliding part in the adjusting part for driving the first telescopic assembly and the second telescopic assembly respectively will be affected by the gravity of the test equipment, so as to be unable to slide relative to the guide rail.
[0016] It can be understood that the ordinary sliding part is affected by the gravity of the heavy test equipment, so as to generate a gravity center offset, that is, the sliding part will generate an additional lateral force relative to the guide rail, so as to jam the guide rail, and the sliding part is unable to move to continue to slide along the guide rail. Further, the sliding part generating the gravity center offset can also continue to deform downward in the first direction, so as to press the guide rail in sliding cooperation therewith, and then the situation that the sliding part is unable to slide is aggravated.
[0017] Therefore, the adjusting part of the embodiment of the present application adopts at least two first guide rails, the at least two first guide rails are arranged in the first direction and extend in the second direction, and the second sliding part in the adjusting part is connected with the at least two first guide rails, and the third sliding part is connected with the at least two first guide rails, that is, if two first guide rails are used for example, the second sliding part is connected with the two first guide rails in sliding cooperation at the same time, and correspondingly, the third sliding part is connected with the two first guide rails in sliding cooperation at the same time.
[0018] Then, since the number of the first guide rails is increased to two (or three, four, or more), the two first guide rails can disperse the pressure received by the first telescopic assembly (connected with the second sliding part) and the second telescopic assembly (connected with the third sliding part), that is, disperse the pressure of the second sliding part and the third sliding part, so as to avoid the gravity center offset of the second sliding part (and the first telescopic assembly connected therewith) and the third sliding part (and the second telescopic assembly connected therewith), and ensure that the second sliding part and the third sliding part can slide relative to the two first guide rails. At the same time, it can further prevent the second sliding part and the third sliding part from deforming to press the corresponding guide rail, and avoid the situation that the second sliding part and the third sliding part are unable to slide.
[0019] According to another specific embodiment of the present application, the adjusting part further comprises a first connecting piece and a second connecting piece, wherein,
[0020] One side of the first connecting piece is connected with the second sliding part, and the other side of the first connecting piece is connected with the first telescopic assembly;
[0021] One side of the second connecting piece is connected with the third sliding part, and the other side of the second connecting piece is connected with the second telescopic assembly.
[0022] According to another specific embodiment of the present application, the second sliding part comprises a plurality of first sliders corresponding to the at least two first guide rails one by one, and each first slider is in sliding fit with the corresponding first guide rail.
[0023] According to another specific embodiment of the present application, the second sliding part comprises a third slider, and the third sliding part comprises a fourth slider, and the third slider and the fourth slider are respectively provided with a plurality of sliding grooves, wherein,
[0024] The number of the sliding grooves of the third slider corresponds to the number of the first guide rails, and the sliding grooves of the third slider are in sliding fit with the corresponding first guide rails;
[0025] The number of the sliding grooves of the fourth slider corresponds to the number of the first guide rails, and the sliding grooves of the fourth slider are in sliding fit with the corresponding first guide rails.
[0026] According to another specific embodiment of the present application, the first telescopic assembly of the telescopic part comprises a first supporting arm and a first sliding groove, and the second telescopic assembly comprises a second supporting arm and a second sliding groove, wherein,
[0027] The first sliding groove extends along the third direction and is connected with the second sliding part, and the second sliding groove extends along the third direction and is connected with the third sliding part;
[0028] Along the third direction, the first supporting arm is in slidable connection with the first sliding groove, and the second supporting arm is in slidable connection with the second sliding groove;
[0029] And the sliding distance of the first supporting arm along the third direction is equal to the length of the first sliding groove, and the sliding distance of the second supporting arm along the third direction is equal to the length of the second sliding groove.
[0030] By adopting the above technical scheme, the first supporting arm can slide relative to the first sliding groove along the third direction, and the second supporting arm can slide relative to the second sliding groove along the third direction, so that the sliding distance of the first supporting arm and the second supporting arm relative to the corresponding sliding grooves can be adjusted to adapt the changing device to test equipment with different depths (i.e. length along the third direction).
[0031] Meanwhile, the sliding distance of the first branch arm is equal to the length of the first sliding groove, and the sliding distance of the second branch arm is equal to the length of the second sliding groove, which means that the pressure between the first branch arm and the first sliding groove and between the second branch arm and the second sliding groove is uniformly distributed during the whole sliding process, and the first and second branch arms have more accurate linear guiding capability. For example, if the sliding distance of the first branch arm is less than the length of the first sliding groove, the first branch arm is prone to deviation during the sliding process, and the second branch arm is the same. Therefore, the first and second telescopic assemblies have better sliding performance, and the first branch arm of the first telescopic assembly and the second branch arm of the second telescopic assembly will not deviate during the sliding process.
[0032] According to another specific embodiment of the utility model, along the first direction, the side of the first branch arm facing the first sliding groove is provided with a fifth sliding block, and the side of the second branch arm facing the second sliding groove is provided with a sixth sliding block, wherein,
[0033] The fifth sliding block extends along the third direction and is in sliding cooperation with the first sliding groove, and along the third direction, the length of the fifth sliding block is equal to the length of the first sliding groove;
[0034] The sixth sliding block extends along the third direction and is in sliding cooperation with the second sliding groove, and along the third direction, the length of the sixth sliding block is equal to the length of the second sliding groove.
[0035] According to another specific embodiment of the utility model, the fifth sliding block and the sixth sliding block are dovetail-shaped protrusions, and the first sliding groove and the second sliding groove are dovetail-shaped.
[0036] By adopting the above technical scheme, the fifth sliding block and the first sliding groove and the sixth sliding block and the second sliding groove are set as dovetail-shaped (i.e. trapezoidal), compared with the traditional rectangular shape, the two inclined surfaces of the dovetail shape are easier to be turned and processed, and the fifth sliding block with such a shape cooperates with the first sliding groove and has a clamping function itself, while the traditional rectangular protrusion and the traditional rectangular sliding groove will fall off along the first direction, if the connection between the traditional rectangular protrusion and the traditional rectangular sliding groove is to be realized, a limiting wall needs to be processed on the inner wall of the rectangular sliding groove, or the sliding groove is directly processed into a back-shaped groove body, and the process is relatively complex.
[0037] According to another specific embodiment of the utility model, the side of the first branch arm away from the second sliding part is provided with a first ear plate, the side of the second branch arm away from the third sliding part is provided with a second ear plate, the first ear plate and the second ear plate are oppositely arranged along the second direction and are respectively used for clamping with the handle of the external device to jointly support the external device.
[0038] According to another specific embodiment of the utility model, the telescopic part further comprises a first adjusting nut and a second adjusting nut; the first supporting arm and the second supporting arm are respectively provided with at least one threaded through hole; the first sliding groove and the second sliding groove are respectively provided with a plurality of adjusting screw holes, and the plurality of adjusting screw holes are arranged at intervals along the third direction, wherein,
[0039] The first adjusting nut is sequentially and threadedly connected with the threaded through hole of the first supporting arm and any one of the plurality of adjusting screw holes of the first sliding groove;
[0040] The second adjusting nut is sequentially and threadedly connected with the threaded through hole of the second supporting arm and any one of the plurality of adjusting screw holes of the second sliding groove.
[0041] According to another specific embodiment of the utility model, the changing device further comprises a counterweight, which is arranged at the bottom of the main body along the first direction.
[0042] By adopting the technical scheme, the counterweight can keep the changing device stable under the conditions of turning, accelerating, uneven load and the like, and avoid the center of gravity from tilting. BRIEF DESCRIPTION OF DRAWINGS

[0053] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.
[0054] Reference Figure 1An embodiment of the present application provides a type changing device 100 , including a main body 110 , a first sliding portion 102 , an adjusting portion 140 and a telescopic portion 150 .
[0055] As can be seen, the main body 110 serves as the supporting portion of the mold changing device 100 according to the embodiment of the present application. The adjustment portion 140 is connected to the main body 110, and the telescopic portion 150 is further connected to the adjustment portion 140. For example, two legs 111 with sliding wheels are provided at the bottom of the main body 110. This allows the mold changing device 100 to be pushed by the operator, saving time and effort. In other words, for example, the mold changing device 100 can be a mold changing cart, but is not limited thereto.
[0056] In one possible implementation, Figure 1 The main body 110 is exemplarily shown to have a trapezoidal structure, but the embodiments of the present application are not limited to this. The main body 110 can also be other shapes, such as a disc, a square, a hexagon, an octagon, etc.
[0057] For example, the embodiment of the present application does not impose any specific restrictions on the number of the above-mentioned legs 111. For example, one, three, four, etc. legs 111 can be provided. For example, the embodiment of the present application does not impose any specific restrictions on the number of sliding wheels installed on each leg 111. For example, one, two, three, four, etc. sliding wheels can be provided. As long as the number of sliding wheels enables the changing device 100 to be pushed, it falls within the scope of protection of the embodiment of the present application.
[0058] Continue to refer Figure 1 The first sliding portion 102 is moved along a first direction (eg Figure 1 The Z direction shown in FIG) is slidably connected to the main body 110 and is used to move along a first direction (such as Figure 1 The Z direction shown in FIG moves relative to the main body 110.
[0059] Specifically, the shape-changing device 100 further includes a fourth sliding portion 103, which extends along the first direction and is fixed to the main body 110, and the first sliding portion 102 can be slidably matched with the fourth sliding portion 103, that is, the first sliding portion 102 is slidably connected to the fourth sliding portion 103, and the first sliding portion 102 can move upward relative to the fourth sliding portion 103 along the first direction (such as Figure 1 Z1 direction shown in the figure) and downward movement (as shown in the figure) Figure 1 Z2 direction shown in FIG).
[0060] Exemplarily, the first sliding part 102 is a sliding block, and the fourth sliding part 103 is a guide rail, and the two sliding parts are slidingly matched along the first direction. Exemplarily, the fourth sliding part 103 can also be a sliding groove. The embodiments of the present application do not make specific limitation on the shape and structure of the first sliding part 102 and the fourth sliding part 103, as long as the first sliding part 102 can move relative to the main body part 110 along the first direction, which falls within the protection scope of the embodiments of the present application.
[0061] With continuous reference to Figure 1 , the adjusting part 140 includes a second sliding part 141, a third sliding part 142 and two first guide rails 143. As can be seen, the two first guide rails 143 are spaced apart along the first direction (for example, the Z direction shown in Figure 1 ) and extend along the second direction (for example, the Y direction shown in Figure 1 ) and are fixed with the first sliding part 102. For example, as shown in Figure 1 , the two first guide rails 143 are arranged on a rectangular plate body which is fixed with the first sliding part 102.
[0062] Further, the second sliding part 141 is slidingly connected with the two first guide rails 143, that is, the second sliding part 141 can slide relative to the two first guide rails 143 along the second direction (for example, the Y direction shown in Figure 1 ).
[0063] The third sliding part 142 is also slidingly connected with the two first guide rails 143, that is, the third sliding part 142 can slide relative to the two first guide rails 143 along the second direction (for example, the Y direction shown in Figure 1 ).
[0064] That is, the operator can adjust either one or both of the second sliding part 141 and the third sliding part 142 in the second direction. For example, the operator can adjust the second sliding part 141 to slide relative to the two first guide rails 143 along the second direction towards the third sliding part 142 (for example, the Y2 direction shown in Figure 1 ).
[0065] For example, the operator can adjust the third sliding part 142 to slide relative to the two first guide rails 143 along the second direction towards the second sliding part 141 (for example, the Y1 direction shown in Figure 1 ).
[0066] For another example, the operator can jointly adjust the second sliding part 141 and the third sliding part 142 with both hands to slide relative to the two first guide rails 143 towards each other or away from each other.
[0067] The above sliding mode of the second sliding part 141 and the third sliding part 142 is not specifically limited in the embodiments of the present application, and can be selected according to actual application conditions.
[0068] In addition, the number of the first guide rails 143 is not limited in the embodiments of the present application. For example, three, four, five or other numbers of the first guide rails 143 can also be provided, as long as the number of the first guide rails 143 can ensure that the second sliding part 141 and the third sliding part 142 normally slide on all the first guide rails 143, which belongs to the protection scope of the embodiments of the present application.
[0069] With reference to Figure 1 , the telescopic part 150 includes a first telescopic assembly 151 and a second telescopic assembly 152, which are used to jointly hold an external device (for example, a test device in a circuit board test process, not shown in the figure). The first telescopic assembly 151 and the second telescopic assembly 152 extend along a third direction (for example, the X direction shown in Figure 1 , the first telescopic assembly 151 is connected with the second sliding part 141, and the second telescopic assembly 152 is connected with the third sliding part 142. And the first telescopic assembly 151 and the second telescopic assembly 152 can respectively extend and retract along the third direction.
[0070] It should be noted that the above first direction (for example, the X direction shown in Figure 1 , for example, the height direction), the second direction (for example, the Y direction shown in Figure 1 , for example, the length direction), and the third direction (for example, the X direction shown in Figure 1 , for example, the width direction) intersect with each other, and the embodiments of the present application are described by taking the perpendicularity of the three directions as an example.
[0071] In some possible implementation manners, the type changing device 100 further includes a counterweight (not shown in the figure), which is arranged at the bottom of the main body part 110 along the first direction (that is, the side indicated by the Z2 direction in Figure 2 . With this technical solution, in the case of turning, accelerating, uneven load, etc., the counterweight can keep the type changing device 100 stable and avoid the center of gravity tilting.
[0072] With reference to Figure 1The type conversion device 100 can be applied to type conversion transportation of different test equipment in printed circuit board assembly (PCBA). That is, the type conversion device 100 can be adjusted in the first direction (for example, the height direction), the second direction (for example, the length direction) and the third direction (for example, the width direction), so as to adapt to test equipment of different sizes and shapes. For example, the sizes and shapes of test equipment used in ICT online testing, FCT functional circuit testing and Flash programming are different. When printed circuit boards are tested one by one, different test equipment needs to be replaced, and the heights, lengths and widths of various test equipment are different. Since the type conversion device 100 can be adjusted in the above three directions, it can be compatible with all test equipment type conversion.
[0073] Specifically, the adjusting part 140 and the telescopic part 150 can simultaneously move relative to the main body part 110 through the first sliding part 102, so as to realize adjustment in the first direction. The telescopic part 150 includes two telescopic assemblies (that is, the first telescopic assembly 151 and the second telescopic assembly 152), which are used to jointly hold external test equipment, and the first telescopic assembly 151 and the second telescopic assembly 152 can each be telescoped in the third direction, so that the first telescopic assembly 151 and the second telescopic assembly 152 can adapt to test equipment of different depths (that is, lengths in the third direction).
[0074] Meanwhile, the first telescopic assembly 151 and the second telescopic assembly 152 are respectively connected with the second sliding part 141 and the third sliding part 142 in the adjusting part 140, and the second sliding part 141 and the third sliding part 142 can slide in the second direction, so as to adapt to test equipment of different widths (that is, lengths in the second direction).
[0075] Therefore, the type conversion device 100 does not need to be manually carried by multiple operators, and only needs to be operated by one operator, so as to avoid waste of human resources, damage to test equipment, injury to operators and other adverse conditions, and can save time for replacing test equipment and has high efficiency.
[0076] On the other hand, since the weight of part of the test equipment is large, if the ordinary adjusting part 140 (that is, the ordinary sliding part and guide rail) is used and the test equipment is held by the first telescopic assembly 151 and the second telescopic assembly 152, the sliding parts in the adjusting part 140 for driving the first telescopic assembly 151 and the second telescopic assembly 152 will be affected by the gravity of the test equipment, so as to be unable to slide relative to the guide rail.
[0077] It can be understood that the weight of the heavier test equipment exerts a center of gravity offset on the standard sliding portion. This creates an additional lateral force on the sliding portion relative to the guide rail, which can cause the sliding portion to jam and prevent it from sliding along the rail. Furthermore, this center of gravity offset may cause the sliding portion to further deform downward in the first direction, compressing the guide rail with which it slidably engages, further exacerbating the sliding portion's inability to slide.
[0078] Therefore, the adjustment portion 140 of the embodiment of the present application adopts at least two first guide rails 143, and the at least two first guide rails 143 are arranged at intervals along the first direction and extend along the second direction. At the same time, the second sliding portion 141 in the adjustment portion 140 is connected to the at least two first guide rails 143, and the third sliding portion 142 is connected to the at least two first guide rails 143. That is to say, if, for example, two first guide rails 143 are used, the second sliding portion 141 is simultaneously slidably connected to the two first guide rails 143, and accordingly, the third sliding portion 142 is simultaneously slidably connected to the two first guide rails 143.
[0079] Then, since the number of first guide rails 143 is increased to two (or more), the two first guide rails 143 will disperse the pressure on the first telescopic assembly 151 (which is connected to the second sliding portion 141) and the second telescopic assembly 152 (which is connected to the third sliding portion 142). In other words, the pressure on the second sliding portion 141 and the third sliding portion 142 is dispersed, thereby preventing the second sliding portion 141 (and the first telescopic assembly 151 connected thereto) and the third sliding portion 142 (and the second telescopic assembly 152 connected thereto) from being offset in center of gravity, ensuring that the second sliding portion 141 and the third sliding portion 142 can slide relative to the two first guide rails 143. At the same time, the second sliding portion 141 and the third sliding portion 142 can be further prevented from deforming and squeezing the corresponding guide rails, thereby avoiding aggravating the disadvantage of the second sliding portion 141 and the third sliding portion 142 being unable to slide.
[0080] refer to Figure 2 Combined with Figure 2 In some possible implementations, the adjustment portion 140 further includes a first connecting member 144 and a second connecting member 145 .
[0081] like Figure 1 As shown, one side of the first connecting member 144 (ie Figure 2 The side indicated by the X2 direction in the middle) and the second sliding portion 141 (as Figure 1 As shown) connection, the other side of the first connecting member 144 (ie Figure 2 The side indicated by the X1 direction in the middle) and the first telescopic component 151 (such as Figure 1 shown) connection;
[0082] At the same time, one side of the second connecting member 145 (ieFigure 2 The other side of the second connecting piece 145 (i.e., the side pointed by the X1 direction) is connected with the second telescopic assembly 152 (as shown in the figure). Figure 1 The other side of the second connecting piece 145 (i.e., the side pointed by the X1 direction) is connected with the second telescopic assembly 152 (as shown in the figure). Figure 2 The other side of the second connecting piece 145 (i.e., the side pointed by the X1 direction) is connected with the second telescopic assembly 152 (as shown in the figure). Figure 3 Exemplarily, the first connecting piece 144 and the second connecting piece 145 are sheet metal pieces.
[0083] With reference to Figure 1 and Figure 4 and in combination with Figure 1 In some possible implementation manners, the second sliding part 141 includes two first sliding blocks 1411, and the third sliding part 142 includes two second sliding blocks 1412, where the number of the first sliding blocks 1411 corresponds to the number of the first guide rails 143 one by one, and each first sliding block 1411 is in sliding fit with a corresponding first guide rail 143.
[0084] The number of the second sliding blocks 1412 corresponds to the number of the first guide rails 143 one by one, and each second sliding block 1412 is in sliding fit with a corresponding first guide rail 143.
[0085] Exemplarily, the number of the first sliding blocks 1411 and the second sliding blocks 1412 is not limited in the embodiments of the application, for example, three, four, five or the like number of the first sliding blocks 1411 and the second sliding blocks 1412 can also be provided, as long as they can correspond to the number of the first guide rails 143 one by one, which all belong to the protection scope of the embodiments of the application. Exemplarily, the first sliding blocks 1411 and the second sliding blocks 1412 are valve blocks.
[0086] In another possible implementation manner, the second sliding part 141 includes one third sliding block (not shown in the figure), and the third sliding part 142 includes one fourth sliding block (not shown in the figure). It can be understood that one third sliding block can be in sliding connection with two first guide rails 143 at the same time, and one fourth sliding block can also be in sliding connection with two first guide rails 143 at the same time.
[0087] Specifically, the third sliding block and the fourth sliding block are respectively provided with a plurality of sliding grooves (not shown in the figure), where the number of the sliding grooves of the third sliding block corresponds to the number of the first guide rails 143 one by one, and the sliding grooves of the third sliding block (not shown in the figure) are in sliding fit with the first guide rails 143.
[0088] Correspondingly, the number of the sliding grooves (not shown in the figure) of the fourth sliding block 1414 corresponds to the number of the first guide rails 143 one by one, and the sliding grooves of the fourth sliding block 1414 are in sliding fit with the first guide rails 143.
[0089] With reference to Figure 4 and in combination with Figure 4In some possible embodiments, the first telescopic component 151 of the telescopic part 150 comprises a first supporting arm 1511 and a first sliding groove 1512, and the second telescopic component 152 comprises a second supporting arm 1521 and a second sliding groove 1522. The first sliding groove 1512 extends along a third direction (e.g., the X direction shown in FIG. 6) and is connected with the second sliding part 141. The second sliding groove 1522 extends along the third direction (e.g., the X direction shown in FIG. 6) and is connected with the third sliding part 142. Specifically, the first sliding groove 1512 is first connected with the first connecting piece 144 (as shown in FIG. 6) and then connected with the second sliding part 141. The second sliding groove 1522 is first connected with the second connecting piece 145 (as shown in FIG. 6) and then connected with the third sliding part 142. Figure 2 Figure 2 Figure 4 Figure 5
[0090] Along the third direction (e.g., the X direction shown in FIG. 6), the first supporting arm 1511 is slidably connected with the first sliding groove 1512, that is, the first supporting arm 1511 can slide relative to the first sliding groove 1512 along the third direction. The second supporting arm 1521 is slidably connected with the second sliding groove 1522, that is, the second supporting arm 1521 can slide relative to the second sliding groove 1522 along the third direction. Figure 5
[0091] Figure 5 Figure 5 An exploded view of the first telescopic component 151 is shown.
[0092] In the embodiments of the present application, the first telescopic component 151 and the second telescopic component have the same structure and arrangement, and thus, the first telescopic component 151 is taken as an example for detailed description herein. It can be understood that the second telescopic component can be arranged by referring to the first telescopic component 151.
[0093] As shown in FIG. 6, the sliding distance of the first supporting arm 1511 along the third direction (e.g., the X direction shown in FIG. 6) (that is, the length L1 of the fifth sliding block 1513 described below) is equal to the length L2 of the first sliding groove 1512. Figure 5 Figure 5 In some possible embodiments, along the first direction (e.g., the Z direction shown in FIG. 6), the side of the first supporting arm 1511 facing the first sliding groove 1512 (that is, the side indicated by the Z2 direction in FIG. 6) is provided with a fifth sliding block 1513. The fifth sliding block 1513 extends along the third direction (e.g., the X direction shown in FIG. 6) and is in sliding cooperation with the first sliding groove 1512. Along the third direction, the length L1 of the fifth sliding block 1513 is equal to the length of the first sliding groove 1512.
[0094] Figure 5 Figure 4 Figure 5
[0095] Correspondingly, the sliding distance of the second arm along the third direction is equal to the length of the second sliding groove, and the side of the second arm facing the second sliding groove is provided with a sixth sliding block extending along the third direction and in sliding fit with the second sliding groove, and the length of the sixth sliding block along the third direction is equal to the length of the second sliding groove.
[0096] With reference to Figure 4 and Figure 5 By adopting the above technical solutions, the first arm 1511 can slide relative to the first sliding groove 1512 along the third direction, and the second arm 1521 can slide relative to the second sliding groove 1522 along the third direction, so that the sliding distance of the first arm 1511 and the second arm 1521 relative to the corresponding sliding groove can be adjusted to make the conversion device 100 applicable to test equipment with different depths (i.e., length along the third direction).
[0097] Meanwhile, the sliding distance of the first arm 1511 (i.e., the length L1 of the fifth sliding block 1513 along the third direction) is equal to the length of the first sliding groove 1512, and the sliding distance of the second arm 1521 (i.e., the length of the sixth sliding block along the third direction) is equal to the length of the second sliding groove 1522, which means that the pressure between the first arm 1511 and the first sliding groove 1512 and between the second arm and the second sliding groove is uniformly distributed and has more precise linear guiding ability during the entire sliding process. For example, if the sliding distance of the first arm 1511 is less than the length of the first sliding groove 1512, the first arm 1511 is prone to deviation during sliding, and the second arm is the same. Therefore, the first telescopic assembly 151 and the second telescopic assembly 152 of the embodiment have better sliding performance, and the first arm 1511 of the first telescopic assembly and the second arm 1521 of the second telescopic assembly will not deviate during sliding.
[0098] In some possible embodiments, the fifth sliding block 1513 and the sixth sliding block are dovetail-shaped protrusions, and the inner walls of the first sliding groove 1512 and the second sliding groove 1522 are dovetail-shaped. Exemplarily, the dovetail-shaped protrusions are trapezoidal protrusions, and the dovetail-shaped inner walls are trapezoidal inner walls.
[0099] According to the technical scheme, the fifth sliding block 1513 and the first sliding groove 1512 and the sixth sliding block and the second sliding groove 1522 are in dovetail type (i.e. trapezoidal), compared with the traditional rectangle, the two inclined surfaces of the dovetail type are easier to be turned, and the fifth sliding block 1513 cooperates with the first sliding groove 1512, and the fifth sliding block 1513 has the clamping function, and the traditional rectangular protrusion and the traditional rectangular sliding groove are separated along the first direction, if the traditional rectangular protrusion and the traditional rectangular sliding groove are connected, a limiting wall needs to be machined on the inner wall of the rectangular sliding groove, or the sliding groove is directly machined into a back-shaped groove, and the process is relatively complex.
[0100] Reference Figure 4 and Figure 4 In some possible embodiments, the side of the first supporting arm 1511 away from the second sliding part 141 is provided with a first ear plate 1514, and the side of the second supporting arm 1521 away from the third sliding part 142 is provided with a second ear plate 1524, and the first ear plate 1514 and the second ear plate 1524 are oppositely arranged along the second direction (e.g. Y direction shown in Figure 2 In some possible embodiments, the first ear plate 1514 and the second ear plate 1524 are respectively used for clamping with the handle (not shown in the figure) of the external device along the first direction (e.g. Z direction shown in Figure 4 In some possible embodiments, the first ear plate 1514 and the second ear plate 1524 are respectively used for clamping with the handle (not shown in the figure) of the external device along the first direction (e.g. Z direction shown in

[0102] According to the foregoing, since the structures and arrangement modes of the first telescopic assembly 151 and the second telescopic assembly are the same, this part will be described in detail only by taking the first telescopic assembly 151 as an example.
[0103] As shown in Figure 5 It can be seen that the plurality of adjusting screw holes 1500 are arranged at intervals along the third direction (e.g. X direction shown in The first supporting arm 1511 and the second supporting arm 1521 are respectively provided with at least one threaded through hole 1501 (as shown in The first adjusting nut 1515 is in threaded connection with the threaded through hole 1501 of the first supporting arm 1511 and any one of the plurality of adjusting screw holes 1500 of the first sliding groove 1512 in sequence (i.e. the Z direction shown in the figure), so as to realize the tightening and loosening between the first supporting arm 1511 and the first sliding groove 1512.
