For clarity of explanation of the technical solution of the present application, upper, lower, front, rear, left and right are defined as shown in fig. 1. Note that, unless otherwise specifically stated, the vertical, front-to-back, and horizontal directions described below refer to the state when the tool box system 100 is left to stand as shown in fig. 1. As shown in fig. 1 to 6, the tool box system 100 includes: handle means 10, running gear 20, storage means 30, auxiliary handle means 20a, locking means 30a and interlocking means 40. The storage device 30 is an integral part of the tool box system 100, the storage device 30 comprises at least one storage box 31, the storage box 31 is used for storing articles, and of course, the tool box system 100 can also comprise a plurality of storage boxes 31, and the interlocking device 40 is used for locking the storage boxes 31. The storage box 31 includes a box body 32 having a receiving chamber 310 and an upper cover 33 for closing the receiving chamber 310, and articles can be stored in the receiving chamber 310. The locking device 30a is used to lock the case 32 and the upper cover 33 so that the case 32 and the upper cover 33 remain relatively fixed. The handle device 10 is connected to a storage box 31, the handle device 10 having a pull rod 11 for being held by a user, the pull rod 11 being movable relative to the storage box 31. Running gear 20 is connected to storage box 31, running gear 20 includes one or more wheels 21, and running gear 20 enables storage box 31 to move relative to the ground. The user can rotate the wheel 21 with respect to the ground by pulling or pushing the pull rod 11 to move the storage box 31. The auxiliary handle device 20a is connected to the storage box 31, and the auxiliary handle device 20a includes a first side wall handle 21a and a second side wall handle 22a provided at left and right side walls 326 of the storage box 31, and a user can hold the first side wall handle 21a and the second side wall handle 22a to lift the storage box 31. In some other embodiments, the tool box system 100 further includes a plurality of storage boxes 31, and the interlocking device 40 is used to connect the storage boxes 31 so that the storage boxes 31 can be kept relatively fixed.

When the tool box system 100 is resting on the ground as shown in fig. 1, the support points of the wheels 21 and the storage box 31 and the ground, both of which comprise at least three support points with the ground, wherein the plane of the three support points is positioned as the support plane P. It should be noted that the ground surface may also refer to other contact surfaces 61 for placing the tool box system 100, and is not limited to the ground. It should also be noted that the present application also includes the toolbox system 100 not having the running gear 20, so that when the storage box 31 is resting on the ground as shown in fig. 1, at least three supporting points are included between the storage box 31 and the ground, and the planes of the three supporting points are defined and positioned as supporting planes, where two supporting planes refer to a plane in the present application unless otherwise specified.

The handle device 10 is provided at the rear side of the storage box 31, and the handle device 10 includes a guide rail 12 for guiding the movement of the pull rod 11 and a locking assembly 13 for locking and releasing the pull rod 11. The guide rail 12 is fixedly connected with the storage box 31, and the locking assembly 13 is connected with the guide rail 12.

Referring to fig. 7 to 14, the pull rod 11 has an active state 111, a locked state 112 and a separated state 113 with respect to the storage box 31. When the pull rod 11 is in the active state 111, the pull rod 11 can be driven to move relative to the guide rail 12, and in particular, when the pull rod 11 is in the active state 111, the user can drive the pull rod 11 to move reciprocally in the extending direction of the guide rail 12. When the pull rod 11 is in the locked state 112, the pull rod 11 moves, the guide rail 12 moves together with the pull rod 11, i.e. when the pull rod 11 moves, the storage box 31 can move together with the pull rod 11, specifically, when the pull rod 11 is in the locked state 112, the locking assembly 13 locks at least part of the pull rod 11 with the guide rail 12 so that the pull rod 11 and the guide rail 12 are kept basically fixed in the extending direction along the guide rail 12, and when a user pulls the pull rod 11 to move, the storage box 31 can move along with the pull rod. It should be noted here that the tie rod 11 remains at least partially fixed to the guide rail 12 in the direction of extension along the guide rail 12, and that only the locking portion 134 of the tie rod 11 to the guide rail 12 remains fixed to the guide rail 12 in the direction of extension along the guide rail 12, and that no movement of the tie rod 11 in the other direction is restricted. When the pull rod 11 is in the disengaged state 113, the pull rod 11 is disengaged from the guide rail 12, i.e. the pull rod 11 can be disengaged from the guide rail 12 as a separate component, although in some other embodiments the pull rod 11 has an active state 111 and a locked state 112, but the disengaged state 113 is absent, i.e. the pull rod 11 is at least partially in contact with the guide rail 12 throughout. In the present embodiment, the pull rod 11 has a separated state 113. In the present application, the extending direction of the guide rail 12 is substantially coincident with the up-down direction, and the guide rail 12 includes a first rail 121 and a second rail 122, which are substantially symmetrically disposed about one bisecting plane a, in the left-right direction.

The tie rod 11 includes a pair of oppositely disposed tie rods, specifically a first tie rod 114 and a second tie rod 115, a grip rod 116 for connecting the pair of tie rods and a separation assembly 14 at a lower end of each tie rod. The two connecting rods are arranged at intervals basically parallel, and the upper ends of the connecting rods are connected with the holding rods 116. The grip lever 116 is at least partially covered by a sleeve to improve the grip of the handle. The sleeve may be made of, for example, rubber, wood, plastic, or any other grip-improving material.

The rear side of the box body 32 of the storage box 31 protrudes backward to form two hollow parts, namely a first hollow part 321 and a second hollow part 322, which penetrate vertically in the vertical direction, and the guide rail 12 is fixedly arranged in the hollow parts. The first rail 121 and the second rail 122 of the guide rail 12 are used for guiding the first connecting rod 114 and the second connecting rod 115, respectively, and the first rail 121 and the second rail 122 are fixedly disposed in the first hollow 321 and the second hollow 322, respectively. The upper and lower ends of the rail are formed with upper and lower through holes through which the connection rod passes, i.e., it can be understood that the lower end of the tie rod 11 can pass through the lower through hole of the rail. Of course, in some other embodiments, the lower end of the pull rod 11 may not pass through the lower through hole of the rail.

The connecting frame 15 connects the first rail 121 and the second rail 122, and the connecting frame 15 is fixedly connected with the first rail 121 and the second rail 122, the locking assembly 13 can be driven by a user, the locking assembly 13 is at least partially disposed in the connecting frame 15, and the locking assembly 13 is used for fixing and maintaining the oppositely disposed first connecting rod 114 and the second connecting rod 115 in the locking state 112. In the present embodiment, the locking assembly 13 is symmetrically disposed about the bisecting plane a, and the locking assembly 13 includes at least: a first transmission member 131, a second transmission member 132, a third transmission member 133, a locking portion 134, and a biasing member 135. The first transmission member 131 can be driven by a user to reciprocate in the first linear direction 101. The second transmission member 132 can be driven by the first transmission member 131 to rotate about the second linear direction 102. The third transmission member 133 is drivable by the second transmission member 132 to move in the third linear direction 103. The locking portion 134 is fixedly provided in the first connecting rod 114, or the locking portion 134 is formed of the first connecting rod 114, the pull rod 11 is in the locking state 112 when the locking portion 134 is in contact with the third transmission member 133, and the pull rod 11 is in the movable state 111 when the locking portion 134 is separated from the third transmission member 133. The biasing member 135 is in contact with the third transmission member 133, and the biasing member 135 can provide a driving force to the third transmission member 133 toward the first connecting rod 114. Specifically, the first transmission member 131 includes a contact portion 1311 and a transmission portion 1312, where the contact portion 1311 is at least partially disposed outside the connection frame 15 and can be contacted by a user, and the transmission portion 1312 is fixedly connected with the contact portion 1311 or integrally formed, that is, the transmission portion 1312 and the contact portion 1311 synchronously move, and the transmission portion 1312 is at least partially contacted with the second transmission member 132, so that the user can press the contact portion 1311 to move the transmission portion 1312 downward along the first linear direction 101, and further the transmission portion 1312 drives the second transmission member 132 to rotate around the second linear direction 102. Further, the transmission portion 1312 is in a long saw-tooth shape, the second transmission member 132 is a gear, and the transmission portion 1312 and the second transmission member 132 are always engaged. The third transmission member 133 passes through the transmission portion 1312 of the first transmission member 131, that is, the transmission portion 1312 has a through hole through which the third transmission member 133 passes, where the third transmission member 133 includes a supporting portion 1331, a driving portion 1332, and a limiting end, the supporting portion 1331, the driving portion 1332 and the limiting end are fixedly connected or integrally formed, the second transmission member 132 and the driving portion 1332 are always engaged, that is, the driving portion 1332 can be driven by the second transmission member 132, and when the second transmission member 132 is driven to rotate around the second linear direction 102, the driving portion 1332 is driven to move along the third linear direction 103 in a direction away from the first connecting rod 114, that is, the limiting end is separated from the locking portion 134, and at this time, the first connecting rod 114 can freely move in the first track 121. One end of the biasing member 135 abuts against the abutting portion 1331, and when the driving portion 1332 moves in a direction away from the first connecting rod 114, the biasing member 135 deforms. When the user releases the first transmission member 131, the biasing member 135 can provide a driving force to the abutting portion 1331, so that the limiting end moves towards the direction approaching the first connecting rod 114. When the biasing member 135 is installed, a biasing force is applied to the biasing member 135, so that the biasing force is applied to the third transmission member 133, and a driving force is applied to the third transmission member 133 in a direction approaching the first connecting rod 114. The biasing member 135 may be a spring.

In fact, the locking portion 134 is a locking hole formed in the first connecting rod 114, and at least two locking holes through which the limiting ends at least pass are formed in the first connecting rod 114 in a direction along which the first connecting rod 114 extends. For convenience of explanation, it is defined herein as a first locking hole 1341 and a second locking hole 1342, the first locking hole 1341 being located at an upper side of the second locking hole 1342 in an extending direction along the first connecting rod 114, and the pull rod 11 being in the locked state 112 when the limit end passes through the locking hole. When the limiting end contacts the first locking hole 1341, the first connecting rod 114 is mostly retracted into the first track 121, which is called that the pull rod 11 is at the first locking position 1343. When the limiting end contacts the second locking hole 1342, the first connecting rod 114 extends out of the first track 121 mostly, which is called that the pull rod 11 is at the second locking position 1344. The draw bar 11 may be placed in the first locking position 1343 for storage when the tool box system 100 is stored. When the user needs to move the tool box system 100, the pull rod 11 may be placed in the second locking position 1344, at which point the user may pull the pull rod 11 to move the tool box system 100. Of course, in some other embodiments, one or more middle locking holes may be disposed between the first locking hole 1341 and the second locking hole 1342, so as to adjust the height of the pull rod 11, which may be convenient for the user to adjust according to his own needs.

Since the locking assembly 13 is symmetrically disposed about the bisecting plane a, that is, the locking assembly 13 and the second connecting rod 115 have the same structure, i.e., the structure and principle of both sides are basically identical, which is not described herein.

As shown in fig. 13 to 19, the lower ends of the first connecting rod 114 and the second connecting rod 115 are respectively provided with a separating assembly 14, which is a first separating assembly 141 and a second separating assembly 142, and since the first connecting rod 114 and the second connecting rod 115 are symmetrically arranged about the bisecting plane a, the first separating assembly 141 and the second separating assembly 142 are also symmetrically arranged about the bisecting plane a, and in order to avoid excessively long description, only the specific structure and principle of the first separating assembly 141 will be described, and the specific structure and principle of the second separating assembly 142 are substantially the same as those of the first separating assembly 141.

The first separating assembly 141 is connected to the first connecting rod 114, the first separating assembly 141 includes a first operating member 1412, the first operating member 1412 is capable of moving in a direction perpendicular or intersecting the extending direction of the first connecting rod 114, the first operating member 1412 includes at least a linkage position 144 and a separating position 145 during movement, when the first operating member 1412 is in the linkage position 144, the first connecting rod 114 cannot be separated from the first rail 121, and when the first operating member 1412 is in the separating position 145, the first connecting rod 114 can be separated from the first rail 121, so that the pull rod 11 can be placed alone. When the draw bar 11 is at the first locking position 1343, the ratio of the distance A1 from the upper cover 33 of the storage box 31 to the supporting plane P in the up-down direction to the distance D2 from the draw bar 11 to the supporting plane P is smaller than 1, that is, the height of the storage box 31 is generally lower than the position of the draw bar 11, in which case, when the user stores the storage box 31, more space is necessary, so that the tool box system 100 can be safely stored, which is inconvenient for the user to manage and store, and the space is wasted. It should be noted that the linkage position 144 and the separation position 145 do not specifically refer to a specific position, but refer to some positions capable of achieving the above functions.

The first separating assembly 141 includes a support 1411, a first operating member 1412, and a stopper 1413. The supporting member 1411 is at least partially disposed in the first connecting rod 114, is fixedly disposed in the first connecting rod 114, and is capable of moving along with the first connecting rod 114. The first operating element 1412 is at least partially disposed within the support 1411, and the first operating element 1412 is capable of reciprocating with the first connecting rod 114 in the direction in which the first connecting rod 114 extends, while the first operating element 1412 is capable of moving relative to the first connecting rod 114 in a direction that intersects or is perpendicular to the direction in which the first connecting rod 114 extends, and a user is capable of actuating the first operating element 1412 to effect a switch between the linkage position 144 and the separation position 145. The stopper 1413 is limited by the first rail 121 and the connection frame 15 such that the stopper 1413 is at least partially secured within the first rail 121, and the stopper 1413 is capable of cooperating with the first operator 1412 to effect a switch between the interlocked position 144 and the disengaged position 145.

Specifically, the supporting member 1411 includes at least a first receiving groove 1414 capable of being clamped with the limiting end, a second receiving groove 1415 for allowing the first operating member 1412 to move, and the first receiving groove 1414 is disposed on the upper side of the second receiving groove 1415 in the vertical direction, that is, when the pull rod 11 is in the first locking position 1343, the first operating member 1412 can be easily contacted by a user through the above arrangement, so as to switch between the linkage position 144 and the separation position 145. In this embodiment, the support 1411 is made of a flexible material.

Referring to fig. 21 to 22, the first operating element 1412 includes a grip portion 1416, a first stopper portion 1417, a second stopper portion 1418, a third stopper portion 1419, and a switching portion 146, and the grip portion 1416, the first stopper portion 1417, the second stopper portion 1418, the third stopper portion 1419, and the switching portion 146 are fixedly connected or integrally formed, and in this embodiment, the grip portion 1416, the first stopper portion 1417, the second stopper portion 1418, the third stopper portion 1419, and the switching portion 146 are integrally formed. The grip 1416 can be actuated by a user, the switch 146 can be configured to cooperate with the support 1411 to effect a position switch, the first stop 1417 can cooperate with the stop 1413, and the second stop 1418 can cooperate with the support 1411. The user pushes the holding portion 1416 forward along the first direction 104, the switching portion 146 is forced to overcome the stopping force provided by the supporting member 1411, and moves forward along the first direction 104 until the second stopping portion 1418 abuts against the supporting member 1411, at this time, the first stopping portion 1417 of the first operating member 1412 extends out of the supporting member 1411 at least partially, and the first operating member 1412 extending out of the supporting member 1411 can abut against the limiting member 1413, so that the first connecting rod 114 cannot be separated from the first rail 121 when moving along the extending direction of the first connecting rod 114.

When the user separates the pull rod 11 from the tool box system 100 according to the requirement, the user only needs to pull the holding portion 1416 backward along the first direction 104, the switching portion 146 is forced to overcome the stopping force provided by the supporting member 1411, and moves backward along the first direction 104 until the third stopping portion 1419 abuts against the first connecting rod 114, the first stopping portion 1417 is substantially completely retracted into the supporting member 1411, at this time, the user pulls the pull rod 11 along the extending direction of the first connecting rod 114, and the pull rod 11 can be separated from the first rail 121.

The support 1411 is provided with a shift portion 147 for switching between the linked position 144 and the disengaged position 145 in cooperation with the first operating member 1412. The shift portion 147 is fixedly connected to the support 1411 or integrally formed, and in this embodiment, the shift portion 147 is integrally formed with the support 1411. The cross section of the shift portion 147 is trapezoidal in the front-rear direction, that is, the shift portion 147 has a first inclined surface and a second inclined surface, the extending direction of the first inclined surface and the extending direction of the second inclined surface obliquely intersect, the first inclined surface is disposed on the front side of the second inclined surface, and also in order to cooperate with the shift portion 147 of the support 1411, the switch portion 146 of the first operating element 1412 has a corresponding first adapting surface 1461 and second adapting surface 1462, the first adapting surface 1461 is disposed on the front side of the second adapting surface 1462, and the cross section of the shift portion 147 is trapezoidal in the front-rear direction. When the user switches the first operating element 1412 from the separated position 145 to the linked position 144, the switching portion 146 is forced to move the first adapting surface 1461 of the switching portion 146 forward against the resistance of the second inclined surface of the shifting portion 147 until the second stop portion 1418 abuts against the supporting element 1411, in order to prevent the first operating element 1412 from retracting during the movement of the pull rod 11, the first inclined surface of the shifting portion 147 is disposed on the retracting path of the first operating element 1412, and the first inclined surface is used for abutting against the second adapting surface 1462, so that the first operating element 1412 is restricted from moving backward along the first direction 104 without external force driving the first operating element 1412, and the first stop portion 1417 always extends out of the supporting element 1411. That is, when the first operating element 1412 is in the linked position 144, the first and second engagement surfaces 1461, 1462 of the switching portion 146 are located on the front side of the first inclined surface of the shifting portion 147. When the user switches the first operating element 1412 from the linkage position 144 to the release position 145, the switching portion 146 is forced to move the second adapting surface 1462 of the switching portion 146 backward against the resistance of the first inclined surface of the shifting portion 147 until the third stopper 1419 abuts against the first connecting rod 114, and also to prevent the first operating element 1412 from protruding during the movement of the pull rod 11, the second inclined surface of the shifting portion 147 is disposed on the path of the first operating element 1412 protruding from the supporting element 1411, and the second inclined surface is adapted to abut against the first adapting surface 1461, so that the first operating element 1412 is restricted from moving forward in the first direction 104 without external force driving the first operating element 1412, and the first stopper 1417 is always retracted into the supporting element 1411. That is, when the first operating element 1412 is in the disengaged position 145, the first and second engagement surfaces 1461, 1462 of the switching portion 146 are located at the rear side of the second inclined surface of the shifting portion 147.

When the first operating member 1412 is in the separated position 145, the pull rod 11 sequentially goes through the first locking position 1343, the movable state 111, the second locking position 1344, and the separated state 113 as the user pulls the pull rod 11 from the bottom to the top in the extending direction of the first connecting rod 114. When the tool box system 100 is placed still, the pull rod 11 is generally at the first locking position 1343, when a user needs to drag the tool box system 100, the user firstly dials the separating assembly 14 to the linkage position 144, then drives the first transmission member 131 of the locking assembly 13 by one hand to withdraw the limiting part from the second locking hole 1342, releases the pull rod 11, holds the holding rod 116 of the pull rod 11 by the other hand, and enables the pull rod 11 to freely move along the extending direction of the first connecting rod 114, which may also be referred to as that the pull rod 11 is in the active state 111, and in the process of holding the pull rod 11 to move upwards, the user can release the first transmission member 131 until the limiting end passes through the second locking hole 1342 due to the driving force of the biasing member 135, so that the pull rod 11 is in the second locking position 1344. Of course, when the user is in the active state 111, the user may continuously press the first transmission member 131, and the biasing member 135 always has a driving force on the limiting portion, that is, the user will continuously abut against the first connecting rod 114 after releasing the first transmission member, so that the user continuously presses the first transmission member 131 to save more effort in the upward moving process of the pull rod 11.

When the tool box system 100 needs to be stored or carried, the tie rod 11 needs to be separated from the tool box system 100. After the user pulls the pull rod 11 to the first locking position 1343, the separating assembly 14 is pulled to the separating position 145, and then the user continuously presses the first transmission member 131 of the locking assembly 13 with one hand to withdraw the limiting end from the second locking hole 1342, release the pull rod 11, hold the holding rod 116 of the pull rod 11 with the other hand, and enable the pull rod 11 to freely move upwards along the extending direction of the first connecting rod 114 until the pull rod 11 is in the separating state 113.

When a user carries the tool box system 100 from a tool storage place to a working place, a plurality of tools, accessories, fan units 60 and the like which need to be used are stored in the storage box 31, the more complicated working places are working conditions, the more tools the user needs to carry, the more tools need to be carried to and fro to the tool storage place and the working place are needed to be carried to the user, the working efficiency of the user is seriously affected, through the arrangement, the user can directly fix the fan units 60 on the storage box 31 when transporting, the user does not need to place the fan units in the containing cavity 310, the space in the containing cavity 310 is released, the user can place more tools in the containing cavity 310, the space utilization rate of the storage box 31 is improved, the reciprocating times of the user can be reduced, and the efficiency of the user is improved. The detachable fixed connection refers to that the fan unit 60 is separated from the storage box 31 on the basis of not damaging the original structures of the fan unit 60 and the storage box 31, for example, the fan unit 60 and the storage box 31 form a snap connection, a screw connection, etc., and of course, a combination of a plurality of connection modes is also possible. The tool box system 100 further comprises a snap-in assembly by which the fan unit 60 is connected to the storage box 31. Specifically, the fan unit 60 may be coupled to the sidewall of the storage box 31 by a snap-fit assembly, or to the upper cover 33 of the storage box 31.

The fan unit 60 and the storage box 31 have at least one contact surface 61, and a distance E1 between the contact surface 61 and the support plane P in the up-down direction is 100mm or more, that is, the contact surface 61 between the fan unit 60 and the storage box 31 may be disposed anywhere from the support plane P to 100mm or more, as long as the connection between the fan unit 60 and the storage box 31 is stable, and the fan unit 60 is not separated from the storage box 31 during the rest or movement of the tool box system 100. Further, in the present embodiment, the tool box system 100 may include one or more storage boxes 31, and the fan unit 60 may be detachably and fixedly connected to any one of the storage boxes 31, that is, a user may stack one or more storage boxes 31 on an upper side of the storage box 31 according to a requirement, so as to implement the height adjustment of the fan unit 60. At the work site, when the user places the fan unit 60 at the work site, the user generally hangs the fan unit 60 at a high place and directly places the fan unit on the ground, that is, the place where the fan unit 60 was placed is relatively fixed, and by using the detachable function between the storage boxes 31 through the above arrangement, the height of the storage boxes 31 can be adjusted to the height required by the user, and then the fan unit 60 is fixed on the storage boxes 31, thereby improving the diversity of user selection. Meanwhile, the tool box system 100 comprises the running gear 20, namely, a user can directly fix the fan unit 60 on the storage box 31 and then push the storage box 31 to enable the fan unit 60 to move along with the storage box 31, and under the working condition that some users replace working sites in a short distance, the user can directly push the storage box 31 or carry the storage box 31 to enable the fan unit 60 to blow against the user, and the user does not need to find a place to place or hang the fan unit 60, so that the working efficiency of the user is improved.

The snap assembly comprises a first snap assembly 41 and a second snap assembly 42, the first snap assembly 41 and the second snap assembly 42 cooperate to lock the fan unit 60, the fan unit 60 being detachably fixedly connected to the upper cover 33 of the storage case 31. The upper cover 33 is provided with a first fastening assembly 41, and the first fastening assembly 41 includes a first fastening member 42, a positioning member 43, and an elastic member 44. The positioning piece 43 is fixedly connected with the fan unit 60 or integrally formed, the first clamping piece 42 is mounted on the upper cover 33, the clamping groove 331 is formed in the upper cover 33, the first clamping piece 42 is arranged in the clamping groove 331, the first clamping piece 42 can move relative to the clamping groove 331, the elastic piece 44 is arranged on the upper cover 33, and the elastic piece 44 is connected with the first clamping piece 42. The first fastening member 42 has at least a first position and a second position relative to the upper cover 33, when the first fastening member 42 is in the first position, the positioning member 43 is kept separate from the first fastening member 42, and when the first fastening member 42 is in the second position, the first fastening member 42 is interlocked with the positioning member 43. When no external force is applied to the first fastening member 42, the elastic member 44 can apply an elastic force to the first fastening member 42 to keep the first fastening member 42 in the second position, that is, the elastic force of the elastic member 44 needs to be overcome when the first fastening member 42 moves from the second position to the first position.

Further, the first locking member 42 is switched between the first position and the second position by rotating, and the first locking member 42 is in the second position, i.e. the positioning member 43 can be locked with the first locking member 42 from top to bottom. The first fastening component 42 is in the first position, i.e., the positioning component 43 is unlocked from the first fastening component 42 and separated from the first fastening component 42. The first position is a position where the first fastening member 42 is turned by a certain angle in a direction away from the positioning member 43, and the first fastening member 42 is reached when the first fastening member 42 is disengaged from the positioning member 43. The second position is a position where the first catch member 42 rotates in a direction approaching the positioning member 43 until it engages with the positioning member 43 and cannot continue to rotate in that direction. When the user realizes the interlocking function of the first fastening piece 42 and the positioning piece 43, the positioning piece 43 is only required to be inserted into the fastening groove 331 of the upper cover 33 from top to bottom, at this time, the first fastening piece 42 is at the second position, when the positioning piece 43 moves downwards towards the inside of the fastening groove 331, the first fastening piece 42 is propped against the first fastening piece 42 and pushed to rotate towards the direction away from the positioning piece 43, and as the positioning piece 43 sinks, the first fastening piece 42 gradually rotates from the second position to the first position under the pushing of the positioning piece 43. When the first fastening member 42 reaches the first position, the positioning member 43 completely enters the fastening slot 331 and is no longer in contact with the first fastening member 42, and cannot continuously push the first fastening member 42 to rotate. After the supporting and pushing action of the positioning element 43 is lost, the first fastening element 42 rebounds from the first position to the second position under the action of the elastic element 44, so that the positioning element 43 is locked in the fastening slot 331. Therefore, the user only needs to insert the positioning member 43 into the locking groove 331 from top to bottom, and the first locking member 42 automatically switches the first locking member 42 from the second position to the first position and back to the second position, thereby automatically completing the interlocking of the first locking member 42 and the positioning member 43. When the first fastening member 42 is detached from the positioning member 43, the first fastening member 42 is rotated to the first position, and the positioning member 43 can be separated from the first fastening member 42, so that the first fastening member 42 and the positioning member 43 can be detached, i.e. the mounting and dismounting processes of the fan unit 60 are very convenient.

The first fastening member 42 is hinged in the fastening groove 331, that is, the first fastening member 42 includes a body 421, a hinge portion 422, a hook 423, a hinge rod 424, a stopper 427, an operation portion 428, and a limiting protrusion 429. The hook 423 is fixedly connected with the body 421 or integrally formed, the hook 423 is disposed at the upper end of the body 421, and the hook 423 is used for being clamped with an interlocking hole formed by the positioning piece 43 to realize the interlocking between the fan unit 60 and the upper cover 33. The hinge portion 422 is fixedly connected with the body 421 or integrally formed, the hinge portion 422 is disposed at the lower end of the body 421, and the hinge portion 422 is connected with the clamping groove 331. The hinge rod 424 passes through both the hinge portion 422 and the clamping groove 331, so that the first clamping member 42 can rotate relative to the clamping groove 331. The operation portion 428 is fixedly connected with the body 421 or integrally formed, and the operation portion 428 is used for driving by a user. The stopper 427 is disposed on the inner side of the body 421, i.e., the side facing the positioning member 43, and the stopper 427 is capable of cooperating with the positioning member 43 to maintain the first locking member 42 in the first position. The limiting protruding portion 429 is fixedly connected with the body 421 or integrally formed, the limiting protruding portion 429 is used for limiting the rotation angle of the first fastening piece 42 and preventing the first fastening piece 42 from falling out of the fastening groove 331, that is, the limiting protruding portion 429 is abutted with one end of the elastic piece 44, and the other end of the elastic piece 44 is abutted with the upper cover 33. In this embodiment, the user drives the first buckle 42 to rotate, and the limiting boss 429 rotates along with the first buckle 42, so that the limiting boss 429 compresses the elastic member 44 until the limiting boss 429 abuts against the upper cover 33. Specifically, the elastic member 44 is specifically a torsion spring.

The stopper 427 includes a main body portion 4271 attached to the main body 421, a telescopic member 4272 provided in the main body portion 4271, and a telescopic elastic member 4273 provided in the main body portion 4271 and connected to the telescopic member 4272. The main body 4271 is connected to the main body 421, and the stopper 427 is rotatable along with the first fastening member 42. The main body portion 4271 is cylindrical, and the expansion elastic members 4273 and 4272 are disposed in the main body portion 4271, and the number of the expansion members 4272 is two and respectively abuts against two ends of the expansion elastic members 4273. In this embodiment, the expansion elastic member 4273 is an expansion spring. Due to the elastic force of the expansion elastic members 4273, in a natural state, one end of the two expansion elastic members 4272 away from the expansion elastic members 4273 protrudes out of the main body portion 4271. When an external force is applied to the two expansion members 4272 to expose one end of the main body portion 4271, the two expansion members 4272 can overcome the elastic force of the expansion elastic members 4273 and retract and even be completely hidden in the main body portion 4271. Because the first fastening piece 42 has a rebound effect, there is a problem that the user always controls the first fastening piece 42 to avoid rebound and lifts the fan unit 60 to separate from the first fastening piece 42, which causes inconvenience to the user. Through the above arrangement, the stopper 427 is disposed on the first locking member 42 and can cooperate with the positioning member 43 to hold the first locking member 42 in the first position, so that the user does not need to manually control the first locking member 42 to hold the first locking member 42 in the first position all the time, and the fan unit 60 and the upper cover 33 can be detached more conveniently. That is, when the first locking member 42 is located at the first position, the interlocking hole and the hook 423 are not in contact, the positioning member 43 and the first locking member 42 are in an unlocked state, and the first locking member 42 does not automatically rebound to the second position, at this time, the user can conveniently remove the fan unit 60.

The hook 423 is disposed inside the first fastening member 42, i.e., near the positioning member 43, and has a substantially triangular shape. In the present embodiment, the number of hooks 423 is two, and the hooks are symmetrically located at two ends of the body 421. The operation portion 428 is located between the two hooks 423, and a user can separate the hooks 423 from the interlocking hole by pulling the operation portion 428. Because the number of the hooks 423 is two, two corresponding interlocking holes which are connected with the hooks 423 in a clamping way are also arranged, and the two corresponding interlocking holes are a first interlocking hole 431 and a second interlocking hole 432 respectively. The first interlocking hole 431 and the second interlocking hole 432 are arranged at intervals, the stopping piece 427 is located between the hooks 423, and the stopping piece 427 is located between the first interlocking hole 431 and the second interlocking hole 432. When the first interlocking hole 431 and the second interlocking hole 432 are disposed at intervals and are located in the clamping groove 331 and cooperate with the hook 423 to lock the fan unit 60 and the upper cover 33, the main body portion 4271 is located between the first interlocking hole 431 and the second interlocking hole 432, and the distance between the first interlocking hole 431 and the second interlocking hole 432 is not smaller than the length of the main body portion 4271. The first interlocking hole 431 and the second interlocking hole 432 are provided with a mating surface 433 on a side close to the main body portion 4271, a first groove 434 and a second groove 435 are respectively provided at a lower end of the mating surface 433, that is, at an end close to the first fastening member 42, the first groove 434 is close to an opening direction of the first interlocking hole 431, the second groove 435 is far from the opening direction of the first interlocking hole 431, and the first groove 434 and the second groove 435 are separated by a protrusion 436. The distance between the protrusions 436 of the first and second interlocking holes 431 and 432 is smaller than the distance between the first and second grooves 431 and 435 of the second interlocking hole 432.

When the positioning member 43 does not completely enter the locking groove 331, the first locking member 42 is at the second position, the extension member 4272 on the positioning member 43 extends out and is exposed to the main body portion 4271 under the elastic force of the extension elastic member 4273, and the extension member 4272 is far away from the protrusion 436 of the first interlocking hole 431 and the second interlocking hole 432. When the positioning member 43 enters the locking groove 331 from top to bottom, the positioning member 43 pushes the first locking member 42 to rotate from the second position to the first position along with the mutual abutment of the positioning member 43 and the hook 423, and the positioning member 43 also rotates along with the first locking member 42. During this process, the extension member 4272 remains extended from the main body portion 4271 and rotates with the first locking member 42 within the range of the second slot 435 until the extension member 4272 rotates to and abuts the boss 436. At this time, the first fastening member 42 is also rotated to the first position, and the hook 423 is no longer abutted against the corresponding interlocking hole. After the abutting is lost, under the action of the elastic force of the elastic member 44, the first buckling member 42 can automatically rebound from the first position to the second position, the telescopic member 4272 also rotates from the position abutting against the boss 436 to the initial position far away from the boss 436, and meanwhile, the buckling hooks 423 are embedded into the interlocking holes on the positioning member 43, so that the fan unit 60 and the upper cover 33 are locked. During the above-described locking process, the expansion member 4272 always rotates in the range of the second groove 435 with the rotation of the first catch member 42.

When the locking between the fan unit 60 and the upper cover 33 needs to be released, the user can pull the first buckle 42 through the operation portion 428 on the first buckle 42, overcome the elastic force of the elastic member 44, and rotate the first buckle from the second position to the first position until the hook 423 completely exits the interlocking hole, and the telescopic member 4272 abuts against the protrusion 436. Continuing to apply force to the first buckle 42 to continue to rotate, the telescopic members 4272 rotate together with the first buckle, and are simultaneously extruded by the protruding portions 436, so that the two telescopic members 4272 retract into the main body portion 4271 against the elastic force of the telescopic elastic members 4273. After the protrusion 436 is not pressed, the two telescopic members 4272 are automatically extended and exposed out of the main body 4271 under the elastic force of the telescopic elastic members 4273. At this time, the user stops applying force to the first fastening member 42, and the first fastening member 42 automatically rotates to the second position under the elastic force of the elastic member 44 until the expansion member 4272 abuts against the protrusion 436. After the external force applied to the first fastening member 42 by the user is lost, the telescopic member 4272 cannot overcome the elastic force of the telescopic elastic member 4273 and retract, and cannot pass over the protrusion 436 and enter the second slot 435. The protrusion 436 abuts the telescoping member 4272 within the first slot 434 to retain the first catch member 42 in the first position. At this time, the end of the expansion member 4272 remote from the expansion elastic member 4273 is also kept in a state of being extended and exposed to the main body portion 4271. Thus, the user can conveniently remove the fan unit 60, and after the user removes the fan unit 60, the first fastening member 42 returns to the second position under the action of the elastic member 44.
