[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0036] This embodiment provides a testing device, such as Figures 1 to 3As shown, it includes a rack frame 1, an inspection door 2, a driving member 3 and an adjusting member 4; the rack frame 1 is provided with an inspection port 11 exposing a motion actuator, and the inspection door 2 is rotatably installed at the inspection port 11, and the two ends of the driving member 3 are respectively rotatably connected to the rack frame 1 and the inspection door 2, and the driving member 3 is used to apply a force to the inspection door 2 to open the inspection port 11; the inspection door 2 has a limiting state for limiting the driving member 3 from opening the inspection door 2 and an unlocking state for allowing the driving member 3 to open the inspection door 2; the adjusting member 4 is movably connected to the inspection door 2, and when the inspection door 2 is in the limiting state, the adjusting member 4 is used to abut against the inner wall of the rack frame 1 to adjust the size of the rotation margin of the inspection door 2.

[0037] Reference Figures 1 to 3 The inspection and maintenance process of the motion actuator is explained in detail. Figure 1 As shown, the test equipment provided by the above embodiment breaks away from the traditional method of using a large sheet metal to enclose the motion actuator, but instead opens an inspection port 11 on the rack frame 1 to expose the motion actuator, and sets an inspection door 2 at the inspection port 11 that can open and close the inspection port. When the motion actuator needs to be repaired, the inspection door 2 is adjusted to the unlocked state, such as Figure 2 As shown, the driving member 3 applies a force to the inspection door 2, forcing the inspection door 2 to rotate counterclockwise, opening the inspection port 11, and the personnel can inspect the motion actuator. After the inspection is completed, the personnel overcome the force of the driving member 3 and close the inspection door clockwise. After the inspection door 2 is closed, the inspection door 2 is adjusted to the limit state. At this time, when the driving member 3 applies a force to the inspection door 2, as shown in FIG. Figure 3 As shown, the adjusting member 4 is against the inner wall of the rack frame, and there is a gap d between the inspection door 2 and the folded edge 12 in the rack frame 1. The inspection door 2 has a certain rotation margin. The personnel can enlarge or reduce the above-mentioned gap d by adjusting the position of the adjusting member 4 relative to the inspection door, so as to adjust the size of the rotation margin of the inspection door 2, and then the fastening state of the inspection door 2 and the flatness between the first outer surface 2121 of the inspection door 2 and the second outer surface 141 of the rack frame 1 can be adjusted.

[0038] The above-mentioned motion actuators include but are not limited to the translation and tensioning actuators at the top of the left and right sliding doors.

[0039] To ensure that the first outer surface 2121 of the inspection door 2 and the second outer surface 141 of the rack frame 1 can be as coplanar as possible, in an optional embodiment, the rack frame 1 has a recessed folded edge 12 corresponding to the inspection opening 11, so that when the inspection door 2 is in a buckled state, its edge can enter the recessed space of the folded edge 12, reducing or even avoiding the inspection door 2 protruding from the outer surface of the rack frame 1.

[0040] It can be understood that the above-mentioned “concave” direction is the direction close to the inside of the rack frame 1 .

[0041] like Figure 3 As shown, when the inspection door 2 is in a limited position, the outer surface of the folded edge 12 facing the outside can limit the angle of the inspection door 2 rotating clockwise relative to the rack frame 1, thereby limiting the rotation of the inspection door 2.

[0042] The folded edge 12 may be formed integrally with other parts of the rack frame 1 ; the folded edge 12 may also be independently provided, in which case the folded edge 12 may be welded to other parts of the rack frame 1 .

[0043] Of course, in some other embodiments, the above-mentioned folded edge 12 may not be provided.

[0044] In an optional embodiment, the rack frame 1 has a folded edge 12 inwardly concave at the inspection opening 11, and when the inspection door 2 is in a limited position, Figure 3 As shown, the adjusting member 4 can abut against the inner surface of the folded edge 12 facing away from the outside, so as to prevent the inspection door 2 from being expanded under the push of the driving member 3.

[0045] When the rack frame 1 is not provided with a folded edge 12 at a position corresponding to the inspection opening 11 , the adjustment member 4 can abut against other inner surfaces of the rack frame 1 .

[0046] In an optional embodiment, if Figure 4 As shown, in order to facilitate the door body 21 to switch between the limited state and the unlocked state, the inspection door 2 includes a door body 21 and a door lock assembly 22, wherein:

[0047] The door body 21 is rotatably mounted at the inspection opening 11 , and the door lock assembly 22 is connected to the door body 21 . The switching between the above two states can be achieved by turning on and off the door lock assembly 22 .

[0048] Among them, the door lock assembly 22 can adopt various forms, such as the more common latch lock in the prior art, which realizes locking through the linear movement or rotational movement of the latch in the latch lock. Any door lock structure that can realize the switching of the inspection door 2 between the limited state and the unlocked state can be used.

[0049] In an optional embodiment, the door lock assembly 22 has a swing arm 221, and the adjustment member 4 is movably connected to the swing arm 221. The swing axis of the swing arm can be as follows: Figure 4 The illustrated embodiment is parallel to the rotation axis of the door body 21 when it is opened and closed, and may also be perpendicular to the first outer surface 2121 of the side door body 21 in the door body 21 .

[0050] When the inspection door 2 is in a limited state, the swing arm 221 can swing to the first position where the adjustment member 4 thereon abuts against the inner wall of the rack frame 1; when the inspection door 2 is in an unlocked state, the swing arm 221 swings to the second position where the adjustment member 4 thereon abuts against the inner wall of the rack frame 1.

[0051] The following is a detailed description:

[0052] When the swing axis of the swing arm is parallel to the rotation axis of the door body 21 when it is opened and closed, Figure 5 The figure shows a schematic diagram of the door lock assembly 22. The door lock assembly 22 includes a swing arm 221, a first housing 222, a button 223, a first spring 224, and a second spring 225; one end of the button 223 is located in the first housing 222 and is hinged to the first housing 222, a first spring 224 is provided between the top of the end and the first housing 222, and the bottom of the end is engaged with one end of the swing arm 221 under the elastic force of the first spring 224, limiting the clockwise rotation of the swing arm 221, and the other end of the button 223 extends out of the first housing 222; the middle part of the swing arm 221 is hinged to the first housing 222, one end of the swing arm 221 close to the button 223 extends into the first housing 222 and is engaged with the button 223, and a second spring 225 is provided between the first housing 222, and the other end of the swing arm 221 extends out of the first housing 222 and is movably connected with the adjustment member 4.

[0053] When it is necessary to open the door 21, Figure 5 As shown, the elastic force of the first spring 224 is overcome and the button 223 is rotated counterclockwise to extend out of the first housing 222, and the button 223 is no longer engaged with the swing arm 221. The swing arm 221 swings clockwise under the push of the second spring 225, and the adjustment member 4 is no longer in contact with the inner wall of the rack frame 1, and swings upward to avoid the second position, so that the door body 21 can be opened smoothly; when it is necessary to adjust the door body 21 to the limited position, the top of the swing arm 221 can be rotated counterclockwise so that the top of the swing arm 221 is engaged with the button 223. Under the elastic force of the first spring 224 and the second spring 225, the button 223 limits the swing arm 221 to be stationary at Figure 5 In the state shown, the swing arm 221 is in the first working position.

[0054] The first spring 224 and the second spring 225 may be coil springs.

[0055] When the swing axis of the swing arm is perpendicular to the first outer surface 2121 of the access door 2, as shown in FIG. Figure 6As shown, it is a schematic diagram of the principle of the door lock assembly 22. The thin dotted line in the figure is the swing axis of the swing arm 221. The door lock assembly 22 includes a second shell 226. The swing arm 221 is hinged to the second shell 226 along the above-mentioned swing axis. One end of the swing arm 221 is provided with a knob 227 extending to the outside of the door body 21, and the other end of the swing arm 221 is movably connected to the adjustment part 4.

[0056] When the door 21 needs to be opened, the swing arm 221 is swung by releasing the constraint on the knob 227, and the adjusting member 4 is no longer in contact with the inner wall of the rack frame 1, and is swung upward to release the rotation constraint on the door 21. At this time, the swing arm 221 is in the second position, and the door 21 can be opened smoothly. When the door 21 needs to be adjusted to the limit state, the swing arm 221 can be dropped back to the limit position by turning the knob 227. Figure 6 In the state shown, the swing arm 221 is in the first position, and the adjustment member 4 abuts against the inner wall of the rack frame 1 .

[0057] It should be noted that the door lock assembly 22 is not limited to the above-mentioned types, and it can also be other types of door lock structures.

[0058] In an optional embodiment, when the door lock assembly 22 has a swing arm 221, the swing arm 221 is provided with a connecting hole, and the adjusting member 4 is threadedly connected to the connecting hole, thereby facilitating the adjustment of the position of the adjusting member 4.

[0059] The rotation axis of the adjustment member 4 is preferably perpendicular to the first outer surface 2121 of the access door 2 .

[0060] The adjusting member 4 is preferably a bolt.

[0061] In an optional embodiment, if Figure 4 As shown, the door body 21 includes a top door body 211 and a side door body 212 connected to the top door body 211 , and one end of the top door body 211 away from the side door body 212 is rotatably connected to the rack frame 1 .

[0062] Compared with the case where the door body 21 only includes the side door body 212 or only includes the top door body 211, the above arrangement can provide a wider field of vision for people when the door body 21 is opened.

[0063] The top door body 211 and the side door body 212 may adopt an integrated structure.

[0064] When the door body 21 includes a top door body 211 and a side door body 212, the driving member 3 can be as follows: Figure 4 As shown, it is rotatably connected to the top door body 211.

[0065] When the door body 21 is opened, the driving member 3 has an outward force to assist the opening of the door body 21; when the door body 21 is closed, the driving member 3 still has an outward force. At this time, the driving member 3 needs to be compressed when the door body 21 falls, so that the driving member 3 gives a resistance to the falling of the door body 21, thereby assisting in reducing the closing speed of the door body 21.

[0066] In some other embodiments, when the door body 21 includes a top door body 211 and a side door body 212 , the driving member 3 is rotationally connected to the side door body 212 .

[0067] In an optional embodiment, when the driving member 3 is rotatably connected to the side door body 212 , one end of the driving member 3 rotatably connected to the rack frame 1 is higher than one end of the driving member 3 rotatably connected to the side door body 212 .

[0068] The above installation method can achieve the purpose of opening angle limit by fully extending the driving member 3 when the door body 21 is opened, and the door body 21 can be suspended at the set opening angle without falling by calculating the elastic force of the driving member 3 and the gravity of the door body 21. When the door body 21 is closed, the force of the driving member 3 changes from upward and outward when opening to downward and outward force, which can significantly reduce the downward force of the operator when closing the door body 21, thereby making the opening and closing of the door body 21 more labor-saving and efficient.

[0069] It should be noted that, those skilled in the art can calculate the balance between the elastic force of the driving member 3 and the gravity of the door body 21 itself based on common knowledge.

[0070] On the basis of the above-mentioned embodiments, the driving member 3 can be selected as a nitrogen spring, which can effectively reduce the speed of opening and closing the door, thereby providing good protection for operators and equipment. The above-mentioned nitrogen spring can be directly purchased from outside.

[0071] In an optional embodiment, if Figure 1 As shown, the rack frame 1 includes a main frame 13 and a door frame beam 14 connected to the main frame 13 , an inspection opening 11 is formed between the door frame beam 14 and the main frame 13 , and a first outer surface 2121 of the side door 212 is flush with a second outer surface 141 of the door frame beam 14 .

[0072] The above arrangement can make the transition between the first outer surface 2121 and the second outer surface 141 smoother and more beautiful in appearance.

[0073] In an optional embodiment, a buckle 5 is rotatably connected to the door body 21 or the rack frame 1. When the door body 21 opens the inspection port 11, the buckle 5 is used to engage with the drive member 3 to limit the rotation of the drive member 3 relative to the door body 21, and there is no need to manually support the door body 21 during the inspection process.

[0074] When the motion actuator of the top automatic door body 21 needs to be maintained, the door body 21 is opened, and the driving member 3 is rotated into the buckle 5. The driving member 3 is held by the buckle 5 to limit the opening and closing of the door body 21, making it easier for personnel to maintain the motion actuator.

[0075] It should be noted that when the buckle 5 is disposed on the door body 21 , the buckle 5 can be pivotally connected to the top door body 211 , and the pivot axis is parallel to the top surface of the top door body 211 and perpendicular to the telescopic direction of the driving member 3 itself.

[0076] When the buckle 5 is arranged on the rack frame 1 , the buckle 5 can be connected to the inner wall of the rack frame 1 through a universal joint, so as to avoid the moving space of the door body 21 and avoid interference with the door body 21 during the opening and closing process of the door body 21 .

[0077] Of course, in some implementations, the buckle 5 may not be provided.

[0078] In an optional embodiment, if Figure 7 As shown, the rack frame 1 is surrounded by an air duct 15 and a receiving space 16 located on the top of the air duct 15 for installing a motion actuator, and the inspection port 11 is arranged opposite to the receiving space 16 .

[0079] The air duct 15 is provided with a heater 6 , an evaporator 7 and the like, and the accommodating space 16 is provided with a fan 8 and the like.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
