[0036] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0037] The core of the present utility model is to provide a shielding mechanism that uses the shielding mechanism to protect the maintenance body and is easy to operate when maintaining the maintenance body.

[0038] The present utility model provides a shielding mechanism for protecting the maintenance body 1, including a shielding member 2, a first mounting seat 3, a second mounting seat 4, and a locking assembly 5.

[0039] Among them, the first mounting seat 3 is used to be mounted on the front of the maintenance body 1. The first end of the shielding member 2 is rotatably arranged on the first mounting seat 3 with the first direction as the axis to shield or expose the maintenance body 1; the second mounting seat 4 is used to be mounted on the front of the maintenance body 1, and the second mounting seat 4 is located on the rotation path of the second end of the shielding member 2; the locking assembly 5 is mounted on the second mounting seat 4 and / or the second end of the shielding member 2 to fix or unlock the second end of the shielding member 2.

[0040] Such as Figure 1As shown, the right end of the shielding member 2 is rotatably arranged on the first mounting seat 3 with the Y direction as the axis through a rotating shaft or hinge, etc. The shielding member 2 can adopt a cover structure or a plate structure, etc., and a locking component 5 is arranged on the second mounting seat 4 and / or the shielding member 2. After rotating the shielding member 2 to make it close to the second mounting seat 4 and after rotating the shielding member 2 to a preset position, adjusting the locking component 5 can lock or unlock the shielding member 2.

[0041] It should be noted that the type of the locking component 5 is not limited. For example, the locking component 5 can adopt a locking tongue rotatably arranged on the second mounting seat 4. Correspondingly, the left end of the shielding member 2 has a clamping structure. During use, open the clamping structure, rotate the locking tongue to make it snap into the clamping structure, and then loosen the clamping structure to clamp the locking tongue, which can limit the shielding member 2 from rotating. Conversely, open the clamping structure and then rotate the locking tongue to make it away from the shielding member 2 to unlock the shielding member 2; or, the locking component 5 can adopt a vacuum suction cup. After the shielding member 2 rotates to abut against the opening of the vacuum suction cup, create a vacuum environment in the inner cavity of the vacuum suction cup to suck tightly the shielding member 2 to limit its rotation. Conversely, remove the vacuum environment in the inner cavity of the vacuum suction cup to unlock the shielding member 2; as long as the locking or unlocking of the shielding member 2 can be realized.

[0042] It should also be noted that the types of the first mounting seat 3 and the second mounting seat 4 are not limited, as long as the above functions can be satisfied.

[0043] During use, install this shielding mechanism on the front of the maintenance body 1 to shield or expose the maintenance body 1 through the shielding member 2. When it is necessary to repair the maintenance body 1, first adjust the locking component 5 to unlock the shielding member 2, and then rotate the shielding member 2 to expose the maintenance body 1. Conversely, after repairing the maintenance body 1, first rotate the shielding member 2 to reset it to shield the maintenance body 1, and then adjust the locking component 5 to lock the shielding member 2.

[0044] To adjust the position of the shielding member 2 in the first direction, on the basis of the above embodiment, the first end of the shielding member 2 is arranged on the first mounting seat 3 through an adjusting component 6, and the adjusting component 6 can drive the shielding member 2 to move along the first direction. It should be noted that the type of the adjusting component 6 is not limited. For example, the adjusting component 6 includes a linear slide rail and a connecting seat. The shielding member 2 is rotatably arranged on the connecting seat, and the connecting seat is slidably arranged on the linear slide rail, and the linear slide rail extends along the Y direction. During use, drive the connecting seat to slide along the Y direction through the linear slide rail, and the movement of the shielding member 2 to different positions can be indirectly adjusted.

[0045] While simplifying the shielding mechanism and ensuring that the shielding member 2 can rotate, on the basis of the above embodiment, the adjusting assembly 6 includes a first gasket 61, a second gasket 62 and a pushing assembly 63; both the first gasket 61 and the second gasket 62 are sleeved outside the rotating shaft connecting the first end of the shielding member 2 and the first mounting seat 3, and the first gasket 61 is located on one side of the shielding member 2 along the first direction, and the second gasket 62 is located on the other side of the shielding member 2 along the first direction; the first end of the pushing assembly 63 abuts against the first gasket 61, the second end abuts against the second gasket 62, and the pushing assembly 63 can push the first gasket 61, the second gasket 62 and the shielding member 2 to move along the first direction.

[0046] As Figure 1 and Figure 2 shown, a first gasket 61 and a second gasket 62 are sleeved outside the rotating shaft where the shielding member 2 is rotatably connected to the first mounting seat 3, and a pushing assembly 63 is arranged on the first mounting seat 3. The first gasket 61 is located on the upper side of the shielding member 2, and the second gasket 62 is located on the lower side of the shielding member 2. Correspondingly, the upper end of the pushing assembly 63 abuts and cooperates with the first gasket 61, and the lower end abuts and cooperates with the second gasket 62. In this embodiment, by adjusting the pushing assembly 63, the position of the shielding member 2 can be adjusted, and under the action of the first gasket 61 and the second gasket 62, the shielding member 2 can rotate smoothly.

[0047] It should be noted that the type of the pushing assembly 63 and the method of arranging it on the first mounting seat 3 are not limited, as long as the above functions can be realized. For example, taking Figure 1 the shown orientation as a reference, the pushing assembly 63 includes a lead screw, a first pushing member and a second pushing member. The lead screw is rotatably arranged on the first mounting seat 3 with the Y direction as the axis. The first pushing member and the second pushing member are both slidably arranged on the first mounting seat 3 along the Y direction, and the first pushing member is in threaded cooperation with one end of the lead screw, and the second pushing member is in threaded cooperation with the other end of the lead screw. The first pushing member abuts against the first gasket 61, and the second pushing member abuts against the second gasket 62. Then, by rotating the lead screw, the first pushing member and the second pushing member can be driven to move synchronously along the Y direction to adjust the position of the shielding member 2.

[0048] To ensure the smooth rotation of the shielding member 2, on the basis of the above embodiment, the number of the first gaskets 61 and the number of the second gaskets 62 are both greater than or equal to two. At least one of the first gaskets 61 and the second gaskets 62 is a metal gasket, and at least one of the first gaskets 61 and the second gaskets 62 is a nylon gasket. And both sides of the two shielding members 2 along the first direction can abut against the nylon gaskets, and the pushing assembly 63 can abut against the metal gaskets.

[0049] As Figure 2As shown in the figure, there are at least two first gaskets 61 on the upper side of the shielding member 2. Among the several first gaskets 61, a nylon gasket is close to the shielding member 2 and can be in direct contact with it, and a metal gasket is far from the shielding member 2 and can be in direct contact with the pushing assembly 63.

[0050] Similarly, as Figure 2 shown in the figure, there are at least two second gaskets 62 on the lower side of the shielding member 2. Among the several second gaskets 62, a nylon gasket is close to the shielding member 2 and can be in direct contact with it, and a metal gasket is far from the shielding member 2 and can be in direct contact with the pushing assembly 63.

[0051] During use, after adjusting the pushing assembly 63, it directly abuts against the metal gaskets on both sides of the shielding member 2, so as to transmit the thrust through the remaining first gaskets 61 and second gaskets 62, thereby pushing the shielding member 2 to move along the Y direction. Under the action of the nylon gasket in direct contact with the shielding member 2, it is beneficial for the smooth rotation of the shielding member 2.

[0052] To facilitate locking the shielding member 2 that moves to different positions along the Y direction, on the basis of the above-mentioned embodiment, the second mounting seat 4 includes a base 41 and a support seat 42. The base 41 is used for mounting on the front surface of the maintenance body 1. The support seat 42 is slidably arranged on the base 41 along the first direction, and the support seat 42 can drive the support seat 42 to move along the first direction through the adjusting member 7; the locking assembly 5 includes a detachably connected first connecting portion 51 and a second connecting portion 52. The first connecting portion 51 is mounted on the support seat 42, and the second connecting portion 52 is mounted on the second end of the shielding member 2, and the first connecting portion 51 is located on the rotation path of the second end of the shielding member 2 to connect or separate from the second connecting portion 52.

[0053] As Figure 1 shown in the figure, in the locking assembly 5, the first connecting portion 51 is mounted on the support seat 42, the second connecting portion 52 is located at the left end of the shielding member 2, and the first connecting portion 51 and the second connecting portion 52 are detachably connected to be able to lock or unlock the shielding member 2.

[0054] It should be noted that the types of the first connecting portion 51 and the second connecting portion 52 are not limited. For example, the first connecting portion 51 is the above-mentioned locking tongue, the second connecting portion 52 is the above-mentioned clamping structure, or both the first connecting portion 51 and the second connecting portion 52 are clamping terminals. During use, the first connecting portion 51 and the second connecting portion 52 can be clamped and matched, etc. As long as the first connecting portion 51 and the second connecting portion 52 can be detachably connected.

[0055] Correspondingly, as Figure 1As shown, the second mounting base 4 includes two parts, namely, a base 41 and a support base 42. The base 41 is used to be directly mounted on the maintenance body 1, and the support base 42 is slidably arranged on the base 41 along the Y direction. In order to adjust the position of the support base 42, an adjusting member 7 capable of driving the support base 42 is arranged on the base 41. It should be noted that the type of the adjusting member 7 is not limited. For example, a screw arranged on the base 41 and threadedly matched with the support base 42, or a driving component of the linear slide rail, etc., can be used as long as it can drive the support to slide.

[0056] It should be noted that there is no limitation on the sliding cooperation mode between the base 41 and the support seat 42. For example, the base 41 may have a slide groove extending along the Y direction, or a linear slide rail installed on the base 41 and extending along the Y direction, as long as the support seat 42 can be slidably arranged on the base 41 along the Y direction.

[0057] It should also be noted that there is no limitation on the way the base 41 and the first mounting seat 3 are arranged on the maintenance body 1, such as welding or threaded connection, as long as the installation requirements can be met.

[0058] In order to improve the ability to lock the shielding member 2 while reducing the difficulty of operation, based on the above embodiment, the second connecting part 52 includes a buckle 521 and a nut structure 522; the buckle 521 can be arranged on the second end shaft portion of the shielding member 2 and rotate relative to it, and is used to hang or move away from the first connecting part 51; the nut structure 522 is threadedly matched with the shaft portion to tighten or loosen the buckle 521.

[0059] like Figure 1 As shown, with respect to the second connecting portion 52, the left end of the shielding member 2 has a columnar protrusion as a rotating shaft portion, and one end of the buckle 521 is arranged on the rotating shaft portion and can rotate relative to the rotating shaft. Optionally, the buckle 521 is sleeved on the outside of the rotating shaft portion, or the rotating shaft portion is provided with a radial through hole, and the buckle 521 passes through the through hole, etc., and in coordination, with respect to the first connecting portion 51, a columnar protrusion is provided on the support seat 42 as the first connecting portion 51, and the buckle 521 can be hung on the first connecting portion 51, for example, sleeved on the outside of the first connecting portion 51, or inserted into a radial hole opened in the first connecting portion 51, etc.

[0060] The outer side of the rotating shaft has a thread, and a nut structure 522 matching with the thread is provided. The nut structure 522 is screwed to make it close to the buckle 521 to tighten it, and the buckle 521 can be loosened by screwing the nut structure 522 in the opposite direction.

[0061] When it is necessary to open the shielding member 2, turn the nut structure 522 to loosen the buckle 521, and then toggle the buckle 521 to separate it from the first connecting portion 51. Then, rotate the shielding member 2 to expose the maintenance body 1. Conversely, when it is necessary to close the shielding member 2, rotate the shielding member 2 so that its left end moves towards the support seat 42 until the shielding member 2 is reset to shield the maintenance body 1. Then, rotate the buckle 521 so that it is hung on the first connecting portion 51, and then turn the nut to press the buckle 521 tightly.

[0062] Preferably, the second end of the shielding member 2 has a plug hole, and the first connecting portion 51 can be inserted into the plug hole. Such a setting is beneficial to a certain extent to ensure that the buckle 521 can be hung on the first connecting portion 51 and is also beneficial to improving the connection strength between the shielding member 2 and the second mounting seat 4.

[0063] To ensure that the buckle 521 can be hung on the first connecting portion 51, based on the above embodiment, a positioning pin 8 is further included. The second end of the shielding member 2 has a first positioning hole, and the support seat 42 has a second positioning hole. When the shielding member 2 rotates to the position where it shields the maintenance body 1, the positioning pin 8 can be inserted into the first positioning hole and the second positioning hole at the same time, and the positioning pin 8 can be pulled out from the second positioning hole. When it is necessary to open the shielding member 2, pull out the positioning pin 8 from the second positioning hole, then turn the nut structure 522 to loosen the buckle 521, and then toggle the buckle 521 to separate it from the first connecting portion 51. Then, rotate the shielding member 2 to expose the maintenance body 1. Conversely, when it is necessary to close the shielding member 2, rotate the shielding member 2 so that its left end moves towards the support seat 42 until the shielding member 2 is reset to shield the maintenance body 1. Then, press the positioning pin 8 into the second positioning hole, and toggle the buckle 521 so that it is hung on the first connecting portion 51, and then turn the nut to press the buckle 521 tightly.

[0064] To reduce the manufacturing and maintenance difficulty of the shielding mechanism, based on the above embodiment, the shielding member 2 includes a shielding member body 21 and a mounting portion 22; the shielding member body 21 is rotatably arranged on the first mounting seat 3, and the first end of the mounting portion 22 is arranged at the second end of the shielding member body 21. The buckle 521, the nut structure 522, and the first positioning hole are all located at the second end of the mounting portion 22. As Figure 1 shown, the right end of the mounting portion 22 is fixedly installed on the left end of the shielding member 2, such as by bolt connection or welding, etc. The left end of the mounting portion 22 is provided with a buckle 521, a nut, and a first positioning hole is provided.

[0065] Preferably, the installation part 22 adopts a bent structure with a right - angle included angle. The first end of the installation part 22 is fixedly installed on the end face of the second end of the shielding part 2, and the installation part 22 is bolt - connected to the shielding part body 21. Such a setting is conducive to improving the strength of the shielding part 2 while simplifying the structure, and this shielding mechanism is convenient for maintenance and has a lower maintenance cost.

[0066] To improve the ability to lock the shielding part 2, on the basis of the above - mentioned embodiment, the first positioning hole is located at the middle position of the shielding part 2 along the first direction, and both sides of the first positioning hole along the first direction have second connecting parts 52; the second positioning hole is located at the middle position of the support seat 42 along the first direction, and both sides of the second positioning hole along the first direction have first connecting parts 51.

[0067] As Figure 1 shown, buckle rings 521 are arranged on both the upper side and the lower side of the installation part 22, and a first positioning hole is opened at the middle position for inserting a positioning pin 8. Correspondingly, first connecting parts 51 are arranged above and below the support seat 42 for cooperating with the corresponding buckle rings 521, and a second positioning hole is opened at the middle position of the support seat 42 for the positioning pin 8 to be inserted, thereby positioning the installation part 22.

[0068] To simplify the structure of this shielding mechanism and reduce the operation difficulty, on the basis of the above - mentioned embodiment, the adjusting part 7 is a threaded rod, the support seat 42 has an installation hole extending along the first direction, and the adjusting part 7 is in threaded cooperation with the installation hole and abuts against the base 41.

[0069] As Figure 1 shown, a threaded through - hole along the Y - direction is opened on the structure extending horizontally at the upper end of the support seat 42 as the installation hole, and an adjusting part 7 in threaded cooperation with it is inserted into the installation hole. When the position of the support seat 42 needs to be adjusted, just turn the adjusting part 7. Assuming that the adjusting part 7 is turned clockwise, the support seat 42 can be driven to move upward along the Y - direction, then when the adjusting part 7 is turned counter - clockwise, the support seat 42 can be driven to move downward along the Y - direction.

[0070] Preferably, correspondingly, the support seat 42 has a long strip through - hole extending along the first direction, the guiding part is inserted into the long strip through - hole, the first end of the guiding part is threadedly connected to the base 41, and the second end of the guiding part can abut against the support seat 42 or be separated from the support seat 42. When the second end of the guiding part is separated from the support seat 42, the support seat 42 can move relative to the base 41. Then, in use, first turn the guiding part to make its second end separated from the support seat 42, operate the adjusting part 7 to drive the support seat 42 to move along the Y - direction, and then turn the guiding part to make its second end abut against the support seat 42, thereby pressing the support seat 42 tightly on the base 41. Such a setting is conducive to simplifying the structure of the second support seat 42.

[0071] In order to simplify the structure of the shielding structure and ensure smooth rotation of the shielding member 2, on the basis of the above embodiment, the pushing assembly 63 includes a plurality of first threaded rods 631 and a plurality of second threaded rods 632, and the first threaded rods 631 extend along the first direction and can abut against the first gasket 61, the second threaded rods 632 extend along the first direction and can abut against the second gasket 62, the plurality of first threaded rods 631 are evenly arranged around the rotation center of the shielding member 2, and the plurality of second threaded rods 632 are evenly arranged around the rotation center of the shielding member 2.

[0072] like Figure 1 As shown, a plurality of first threaded rods 631 extending along the Y direction abut against the first gasket 61 located above the shielding member 2, and a plurality of first threaded rods 631 are evenly arranged around the rotation center of the right end of the shielding member 2; similarly, a plurality of second threaded rods 632 extending along the Y direction abut against the second gasket 62 located below the shielding member 2, and a plurality of second gaskets 62 are evenly arranged around the rotation center of the right end of the shielding member 2. When it is necessary to adjust the position of the right end of the shielding member 2 along the Y direction, firstly screw the first threaded rod 631 located above to move upward to leave a preset distance for the shielding member 2 to move, and then screw the first threaded rod 631 located below to move upward to leave a preset distance for the shielding member 2 to move. The second threaded rod 632 on the right side moves upward to lift the shielding member 2 until the first gasket 61 located at the top abuts against the first threaded rod 631, thus completing the operation of moving the shielding member 2 upward. Alternatively, the second threaded rod 632 located at the bottom is first twisted to move downward to leave a preset distance for the shielding member 2 to move, and then the first threaded rod 631 located at the top is twisted to move it downward until the first threaded rod 631 abuts against the first gasket 61 located at the top, thus completing the operation of moving the shielding member 2 downward. Such a configuration is conducive to uniform force on the shielding member 2 and is relatively easy to operate.

[0073] In order to improve the smoothness of rotation of the shielding member 2 and reduce the volume of the shielding mechanism, based on the above embodiment, a sliding bearing is provided on the outside of the rotating shaft connecting the shielding member 2 and the first mounting seat 3, so that the shielding member 2 can rotate smoothly and slide smoothly along the Y direction.
