The positioning assembly 150 in the locked position is used to position the tray 130 such that the tray 130 is secured. The hinge shaft 170 is spaced apart from the positioning assembly 150 in the height direction of the cabinet 100. Therefore, the positioning assembly 150 can limit the tray 130 in the overturning direction, so that the positioning assembly 150 can limit the overturning of the tray 130.

Specifically, the tray 130 includes a slide rail 131, and an extending direction of the slide rail 131 is substantially parallel to a moving direction of the tray 130. The slide rail 131 can play a guiding role for the movement of the tray 130. The positioning assembly 150 is disposed through the sliding rail 131. The positioning assembly 150 in the unlocked position is capable of relative movement with the sliding rail 131. In this way, the positioning assembly 150 in the unlocked position and the tray 130 are able to move relative to each other. Thus, the positioning assembly 150 in the unlocked position does not restrict the movement of the slide rail 131, ensuring that the tray 130 can move between the closed position and the open position.

The positioning assembly 150 enables the pallet 130 to hover. The tray 130 further includes a positioning groove 132, and the positioning groove 132 protrudes from the sliding rail 131. The protruding direction of the positioning groove 132 intersects with the extending direction of the slide rail 131. The positioning groove 132 is connected to the positioning assembly 150 in the locking position, and the sliding rail 131 does not move with respect to the positioning assembly 150 in the locking position, so that the tray 130 does not move with respect to the cabinet 110, thereby allowing the tray 130 to be positioned. Thereby, the tray 130 is ensured not to move.

According to the cabinet 100 of the application, the cabinet 100 comprises a cabinet body 110, a tray 130 and a positioning assembly 150, the tray 130 is hinged with the cabinet body 110, the tray 130 comprises a sliding rail 131 and a positioning groove 132 protruding from the sliding rail 131, the positioning assembly 150 can move between an unlocking position and a locking position relative to the cabinet body 110, the positioning assembly 150 is arranged in the sliding rail 131 in a penetrating mode, the tray 130 can turn over relative to the cabinet body 110, the positioning assembly 150 located at the unlocking position and the sliding rail 131 can move relatively, and the positioning groove 132 is connected with the positioning assembly 150 located at the locking position so that the tray 130 can be positioned.

In order to facilitate movement of the operating member 151, as shown in fig. 8 and 9, the operating member 151 includes a sleeve 155 and a handle 156, and the sleeve 155 is configured in a cylindrical structure. The sleeve 155 is inserted into the mating hole, and the sleeve 155 is movable with respect to the mating hole. The sleeve 155 and the handle 156 are detachably connected. The handle 156 can be inserted into the sleeve 155, and the handle 156 and the sleeve 155 are connected together by a connector such as a bolt. The handle 156 is located on the exterior of the cabinet 110. The handle 156 may be constructed in a flat configuration to facilitate manual manipulation by an operator.

To facilitate connection of the positioning assembly 150 in the locked position with the positioning slot 132, the positioning assembly 150 further includes a first limiting member 152, where the first limiting member 152 is located inside the cabinet 110. The first stopper member 152 is located outside the tray 130. The first stopper member 152 is connected to the operating member 151. In particular, the first stop member 152 is connected to the sleeve 155. The sleeve 155 and the first stop member 152 may be integrally formed. The first limiting member 152 protrudes from the sleeve 155 in a radial direction of the sleeve 155. The first stop member 152 of the positioning assembly 150 in the unlocked position is spaced apart from the slide rail 131. In this way, the first stop member 152 of the positioning assembly 150 in the unlocked position does not interfere with the rotation of the sliding rail 131. The first limiting member 152 of the positioning assembly 150 located at the locking position is engaged with the positioning groove 132. In this way, the first stopper member 152 of the positioning assembly 150 in the locked position blocks the sliding rail 131 from rotating, thereby maintaining the tray 130 in either of the open positions.

In order to ensure the accuracy of the movement of the operating member 151, the positioning assembly 150 further includes a second limiting member 153, and the second limiting member 153 is located outside the cabinet 110. The second and first stopper members 153 and 152 are located on both sides of the upright 111 in the first direction D1, respectively. The second limiting member 153 and the sleeve 155 may be detachably coupled together by a screw coupling. The second spacing member 153 has a size larger than the size of the mating hole. In particular, the dimension of the second stopper member 153 in the radial direction of the fitting hole is larger than the diameter of the fitting hole. In this way, the second limiting member 153 can abut against the cabinet 110. In particular, the second limiting member 153 can abut against the upright 111, thereby preventing the operating member 151 from moving.

The second stopper member 153 can restrict displacement of the operating member 151 in the first direction D1. The second limiting member 153 of the positioning assembly 150 located at the locking position abuts against the cabinet 110. In this way, the cabinet 110 blocks the second limiting member 153 from moving further in the first direction D1. When the second limiting member 153 abuts against the cabinet 110, the first limiting member 152 is inserted into the positioning slot 132 to block the rotation of the tray 130, thereby fixing the tray 130.

The second limiting member 153 of the positioning assembly 150 in the unlocking position is spaced apart from the cabinet 110. The operating member 151 at the unlock position moves in the direction of the tray 130 along the first direction D1, the second limiting member 153 moves in the direction of the cabinet 110, and the first limiting member 152 moves in the direction of the tray 130. The operating member 151 in the unlocked position moves to the locked position, the first limiting member 152 of the positioning assembly 150 in the locked position engages with the positioning slot 132, and the second limiting member 153 abuts against the cabinet 110. Thereby, the accuracy of positioning the tray 130 is ensured.

In order to prevent the positioning assembly 150 from separating from the tray 130, the positioning assembly 150 further includes a third limiting member 154, and the third limiting member 154 is located inside the tray 130. The first and third limiting members 152 and 154 are located at both sides of the sidewall 136 along the first direction D1, respectively. The third stop member 154 and the sleeve 155 may be removably coupled together by threaded connection. The third limiting member 154 has a size larger than that of the slide rail 131. The positioning groove 132 protrudes from the sliding rail 131. The size of the positioning groove 132 in the radial direction of the slide rail 131 is larger than the size of the slide rail 131. In order to avoid the third limiting member 154 from penetrating out through the positioning groove 132, the size of the third limiting member 154 is larger than the size of the positioning groove 132. Thereby, the third stopper member 154 can abut against the side wall 136 of the tray 130 to restrict displacement of the operating member 151 in the first direction D1 in a direction away from the tray 130. The positioning assembly 150 can be in a modularized design, and each component is convenient to split and install.

To enable the tray 130 to remain in the closed position, as shown in fig. 12, the cabinet 100 further includes a closure assembly 180, the closure assembly 180 connecting the tray 130 and the cabinet 110 in the closed position. The closure assembly 180 includes a locking ring 181, a locking hole 182 (the locking hole 182 is shown in fig. 6), and a latch 183, the axial direction of the locking ring 181 being perpendicular to the axial direction of the locking hole 182. The locking ring 181 is inserted into the locking hole 182. The locking ring 181 is inserted into the locking hole 182 in the axial direction of the locking hole 182. The locking ring 181 includes a central hole, and a portion of the central hole of the locking ring 181 located in the locking hole 182 is exposed. The latch 183 is inserted into the locking ring 181. In particular, the latch 183 is inserted into the exposed center hole of the locking ring 181 to fix the locking ring 181 and the locking hole 182.

One of the cabinet 110 and the tray 130 is provided with a locking ring 181, and the other is provided with a locking hole 182. For example, in the embodiment shown in fig. 12, the cabinet 110 is provided with a locking ring 181 and the bottom wall 137 of the tray 130 is provided with a locking hole 182. The locking holes 182 of the tray 130 in the closed position correspond to the positions of the locking rings 181. The locking ring 181 is inserted into the locking hole 182 of the tray 130 in the closed position. The latch 183 is inserted into the locking ring 181 and the latch 183 abuts the tray 130 in the closed position. In this way, the tray 130 located at the closed position can be prevented from falling down. Of course, in an embodiment not shown, the cabinet 110 is provided with a locking hole 182 and the tray 130 is provided with a locking ring 181.
