DETAILED DESCRIPTION

[0035] In order for the personnel in the technical field to better understand the utility model scheme, the technical scheme in the utility model embodiments will be described clearly and completely below in combination with the drawings in the utility model embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the personnel in the field without making creative labor should belong to the protection scope of the utility model.

[0036] In order for the personnel in the technical field to better understand the utility model scheme, the technical scheme in the utility model embodiments will be described clearly and completely below in combination with the drawings.

[0037] As shown in Figure 1 , Figure 2 and Figure 3 , the machine room cold aisle maintenance tool comprises a sleeve 1, a lifting part is arranged near the top end of the sleeve 1, the tool is convenient to hold through the lifting part; a self-locking structure 3, a compression structure 4 and a transmission mechanism 5 are arranged in the sleeve 1 from top to bottom, a center rod 6 is further arranged on the sleeve 1, the center rod 6 is connected with part of the self-locking structure 3, the compression structure 4 and the transmission mechanism 5, the self-locking structure 3 is driven to move, the compression structure 4 is compressed and the transmission mechanism 5 is driven to move through pressing the center rod 6;

[0038] Since the hooking rod 7 is connected to the transmission mechanism 5, and the transmission mechanism 5 can convert the received movement into rotary movement, when the part of the transmission mechanism 5 rotates, the hooking rod 7 is driven to rotate, so when the tool is used and the hooking rod 7 is extended through the hole below the ventilation floor, the hooking rod 7 is passively rotated to be horizontally blocked on the ventilation floor, and is forced to be pulled up and is pulled off the ventilation floor under the driving of the hooking rod 7, and finally the transmission mechanism 5 is rotated again to drive the hooking rod 7 to rotate, so that the hooking rod 7 is reset to the initial state (see below for details), and the hooking rod 7 in this state can be pulled out of the hole on the ventilation floor and enter.

[0039] As shown in Figure 1 , Figure 2 and Figure 3 , the pulling part includes at least one handle 8 rotatably connected to the sleeve 1, two handles 8 are shown in the figure, and the supporting mechanism 2 includes a sleeve shell 21, a blocking ring 22 and at least one connecting rod 23 (the number is determined according to the number of handles 8), the sleeve shell 21 is slidably sleeved outside the sleeve 1, the blocking ring 22 is fixed outside the sleeve 1, and the diameter of the blocking ring 22 is greater than the diameter of the sleeve shell 21, one end of the connecting rod 23 is rotatably connected to one side of the sleeve shell 21, and the other end of the connecting rod 23 is rotatably connected to the bottom of one end of the handle 8;

[0040] The handle 8 can be limited to a parallel and easy-to-grasp state by the supporting mechanism 2, and the handle 8 can also be limited to a state of being close to the sleeve 1 for storage in a corner, and the two states are switched by the active movement of the sleeve shell 21. Specifically, when the sleeve shell 21 slides upwards outside the sleeve 1 until it contacts the blocking ring 22, the connecting rod 23 rotatably connected to the sleeve shell 21 and the handle 8 presents an inclination angle of about forty-five degrees, so as to support the handle 8 to be parallel to the vertical sleeve 1; when the sleeve shell 21 slides downwards outside the sleeve 1 away from the blocking ring 22, the connecting rod 23 is pulled to be close to the vertical angle and is attached to one side of the sleeve 1, and the connecting rod 23 pulls the handle 8 to rotate at the connection point with the sleeve 1, and the other end approaches the sleeve 1, so as to fold the handle 8 on the sleeve 1.

[0041] As shown in Figures 4-6 , the self-locking structure 3 includes an upper tooth column 31, a locking piece 32, a lower tooth column 33 and a lining cylinder 34, the opposite ends of the upper tooth column 31 and the lower tooth column 33 are each provided with a plurality of inclined surfaces 35, the upper tooth column 31 is provided with a first guide groove 36 adapted to the locking piece 32, the lower tooth column 33 is provided with at least two second guide grooves 37 adapted to the locking piece 32, the first guide groove 36 and the inclined surface 35 are arranged alternately on the upper tooth column 31, the second guide groove 37 and the inclined surface 35 are arranged alternately on the lower tooth column 33, the locking piece 32 is fixed to the sleeve 1, and the lining cylinder 34 is located at the bottom of the lower tooth column 33;

[0042] A button 9 is fixed to the top of the center rod 6. The bottom end of the center rod 6 passes through the upper toothed column 31, the locking member 32, the lower toothed column 33, the bushing 34 and the compression structure 4 and is then fixed to a part of the transmission mechanism 5. A part of the center rod 6 is fixed to the inside of the upper toothed column 31.

[0043] Pressing the center rod 6 with button 9 will cause the upper toothed column 31 to move downward within the sleeve 1. Then, the upper toothed column 31 presses down on the lower toothed column 33, causing the locking member 32, which was originally located in the second guide groove 37 on the lower toothed column 33, to disengage and finally enter the first guide groove 36 on the upper toothed column 31. Because the locking member 32 is fixed to the inner wall of the sleeve 1, it will not move with the movement of the upper toothed column 31 and the lower toothed column 33. Instead, it will switch the position of the first guide groove 36 and the second guide groove 37. That is, the first guide groove 36 on the upper toothed column 31 will come to the locking member 32 as it moves downward.

[0044] After the locking member 32 disengages from the second guide groove 37 of the lower toothed column 33, the inclined surface 35 on the upper toothed column 31 will slide and cut the inclined surface 35 on the lower toothed column 33. At this time, the lower toothed column 33 is not restricted by the locking member 32 and rotates slightly on the bushing 34, so that the inclined surface 35 on the upper toothed column 31 and the inclined surface 35 on the lower toothed column 33 contact the side protrusion. The angle of the slight rotation of the upper toothed column 31 causes the locking member 32 and the inclined surface 35 of the lower toothed column 33 located in the first guide groove 36 of the upper toothed column 31 to be in the same vertical direction. Finally, under the elastic reset of the compression structure 4, the bottom end of the locking member 32 also contacts the inclined surface 35 of the lower toothed column 33. Under the elastic reset stroke of the compression structure 4, the inclined surface 35 on the upper toothed column 31 moves up to the side above the side protrusion of the inclined surface 35 on the lower toothed column 33, thereby limiting the length of the downward transmission of the center rod 6; the above steps are repeated when pressing again.

[0045] The liner 34 moves downwards to compress the structure 4 due to the movement of the lower toothed column 33. When the liner 34 does not compress the structure 4, it transmits the upward restoring force of the compression structure 4 to the lower toothed column 33 located at the top.

[0046] Furthermore, such as Figure 7 As shown, the compression structure 4 includes a spring 41 and a baffle 42. The baffle 42 is fixed inside the sleeve 1, and the spring 41 is located on the baffle 42. The bottom end of the bushing 34 extends downward and contacts the top of the spring 41. The bottom end of the bushing 34 is pressed by the movement of the lower toothed column 33, which compresses the spring 41 located on the baffle 42. The spring 41 is compressed, allowing the bushing 34 to move downward. The bottom end of the center rod 6 not only passes through the upper toothed column 31, the locking member 32, the lower toothed column 33, and the bushing 34, but also passes through the spring 41 and the baffle 42 and is partially fixed to the transmission mechanism 5, so that the center rod 6 moves downward to transmit the linear driving force to the transmission mechanism 5.

[0047] Further, the transmission mechanism 5 comprises a blocking shell 51 fixedly connected to the bottom of the sleeve 1, a gear 52 rotatably connected in the blocking shell 51, and a rack 53 vertically arranged between the sleeve 1 and the blocking shell 51 and engaged with the gear 52, the top end of the rack 53 is fixed to the bottom end of the central rod 6, and the bottom end of the rack 53 can extend out of the blocking shell 51, the hook rod 7 is connected to the gear 52 through the connecting body 10, and is further rotated by the rotation of the gear 52.

[0048] When the central rod 6 moves downward, the rack 53 moves downward, and the engaged gear 52 rotates, the rotation of the gear 52 further drives the hook rod 7 to rotate, so that the hook rod 7 is in a parallel state with the vertical sleeve 1, and the hook rod 7 in this state can hook up the ventilation floor.

[0049] In some examples, as shown in Figure 8 the connecting body 10 is fixed between the hook rod 7 and the gear 52 along a first direction (i.e. a transverse direction intersecting the length direction of the sleeve 1), specifically, one end of the connecting body 10 is fixed to one end of the hook rod 7, and the other end passes through the blocking shell 51 and is fixed to the rotating shafts on both sides of the gear 52, and the blocking shell 51 is not only provided with a through hole through which the bottom end of the rack 53 can extend out, but also provided with a through groove through which the connecting body 10 can rotate along with the gear 52, and the hook rod 7 of the connecting body 10 is arranged to be close to perpendicular to the length direction of the sleeve 1 and between the sleeve 1 and the blocking shell 51;

[0050] Specifically, in this embodiment, the gear 52 is rotated by 80 degrees by the downward movement of the rack 53 driven by the central rod 6, and the gear 52 is rotated by 10 degrees by the rebound movement of the rack 53 driven by the central rod 6 (the central rod 6 is rebounded by the spring 41), and the hook rod 7 is rotated by 80 degrees by the gear 52 through the connecting body 10 with the rotating point being the axis of the gear 52, and after removing the rebound degree, as shown in Figure 1 when the hook rod 7 needs to be folded to be detached from the floor after hooking up the ventilation floor, the gear 52 is further rotated by 10 degrees through the connecting body 10 in the direction of the unfolded state angle as shown in Figure 1 , and finally rotated by 80 degrees in the opposite direction to be folded on one side of the sleeve 1, so as to be detached from the ventilation floor, the shape of the hook rod 7 is only schematic and is not limited here, and can be determined according to actual application.

[0051] In some embodiments, as shown in Figure 9As shown, the connecting body 10 is fixed between the hook rod 7 and the gear 52 along the second direction (i.e. the vertical direction consistent with the length direction of the sleeve 1), specifically, one end of the connecting body 10 is fixed with one end of the hook rod 7, and the other end is fixed with the rotating shaft on both sides of the gear 52 by passing through the blocking shell 51, and the blocking shell 51 is not only provided with a through hole for leaking out the bottom end of the rack 53, but also provided with a through groove for not limiting the rotation of the connecting body 10 following the rotation of the gear 52, and the hook rod 7 of the connecting body 10 is vertically located at the bottom of the blocking shell 51;

[0052] Specifically, in the present embodiment, the rack 53 is driven by the descending movement of the center rod 6 to rotate the gear 52 by ninety degrees, and the rack 53 is driven by the rebound movement of the center rod 6 to rotate the gear 52 by ten degrees, and the gear 52 drives the hook rod 7 to remove the ninety degrees of rotation after rebounding through the connecting body 10 with the axis of the gear 52 as the rotation point, as shown in the hook rod 7 state in Figure 1 When the hook rod 7 needs to be folded to be detached from the board after completing the hooking of the air baffle, the gear 52 continues to rotate ten degrees in the direction of the unfolded state angle as shown in Figure 1 , i.e. continues to rotate ten degrees towards the center rod 6, and finally rotates ninety degrees in the opposite direction to reset at the bottom of the blocking shell 51, and then can be detached from the ventilation floor, and the shape of the hook rod 7 is only schematic and is not limited here, and is determined according to actual application.
