[0043] The glass partition plate 3, the workbench 10 and the cabinet body 1 can form a sealed work area, and the lifting of the glass partition plate 3 can adjust the size of the opening through which the operator's hand extends into the work area.

[0044] In order to exclude the original air in the work area, in the embodiment, as shown in Figure 2 and Figure 4 , it further comprises a first filter 71, a second filter 72, a centrifugal fan 73 and a static pressure tank 74, wherein the second filter 72 is installed at the top of the work area, and the second filter 72 is used to deliver clean air to the work area, and the workbench 10 is provided with an air outlet 101, so that the air in the work area is discharged downward from the air outlet 101;

[0045] Specifically, the first filter 71 is installed at the air inlet of the centrifugal fan 73, the static pressure tank 74 is installed at the air outlet of the centrifugal fan 73, and the air outlet of the static pressure tank 74 points to the second filter 72, so as to realize the filtering treatment of the air.

[0046] In order to realize the stable up-and-down sliding of the glass partition plate 3, in the embodiment, as shown in Figure 3 and Figure 5As shown in the drawings, the glass partition 3 is provided with a frame 32, and the side wall of the frame 32 is provided with a guide rib 321. The inner wall of the track 2 is provided with a sliding groove 21 arranged along the longitudinal direction, and the guide rib 321 is inserted into the sliding groove 21, and the side wall of the guide rib 321 is in sliding connection with the inner wall of the sliding groove 21, so that the stable sliding of the glass partition 3 is realized.

[0047] When the worker is working, the gravity of the glass partition 3 will be applied to the arm of the worker, the arm is compressed, the blood circulation is affected, and the normal work of the worker is affected.

[0048] Therefore, in the embodiment, as shown in the drawings, Figure 2 , Figure 6 and Figure 7 , the side wall of the frame 32 is provided with a longitudinal rack 31, the track 2 is provided with a locking tooth 4 matched with the rack 31, and a driving mechanism 5 for driving the locking tooth 4 to move is further included, as shown in the drawings, Figure 7 when the locking tooth 4 is inserted into the tooth groove of the rack 31, the locking of the glass partition 3 is realized, and the downward movement of the glass partition 3 under the action of its own gravity is prevented, and when the driving mechanism 5 drives the locking tooth 4 to move away from the tooth groove of the rack 31, as shown in the drawings, Figure 9 at this time, the locking tooth 4 releases the restriction of the glass partition 3, so that the glass partition 3 can move downward.

[0049] It is worth mentioning here that the rack 31 and the locking tooth 4 are both provided with two groups and are arranged on both sides of the glass partition 3, so that the stable locking of the glass partition 3 is realized.

[0050] As shown in the drawings, Figure 7 or Figure 9 , the longitudinal section of the locking tooth 4 is a right triangle, the locking surface of the locking tooth 4 is horizontally arranged, the guide inclined surface of the locking tooth 4 is obliquely arranged, the tooth groove of the rack 31 is matched with the locking tooth 4, when the locking tooth 4 is inserted into the tooth groove of the rack 31, the vertical downward sliding of the glass partition 3 can be restricted, but under the action of the upward thrust of the glass partition 3, the guide inclined surface of the locking tooth 4 cooperates with the tooth groove of the rack 31, and the glass partition 3 is pushed upward, so that the one-way movement of the glass partition 3 is realized, and at this time, the locking tooth 4 has the function of one-way locking.

[0051] When it is needed to move the glass partition 3 downward, the driving mechanism 5 is used to drive the locking tooth 4 to interact away from the glass partition 3, so that the locking tooth 4 releases the locking of the glass partition 3, and the downward movement of the glass partition 3 is facilitated.

[0052] Specifically, in order to make the locking tooth 4 stably slide and release the restriction of the glass partition 3, as shown in the drawings, Figure 7As shown, the driving mechanism 5 comprises a transmission plate 51, the locking teeth 4 are fixedly installed on the transmission plate 51, the side wall of the cabinet body 1 is further provided with a guide hole 11, a guide rod 12 is slidingly connected in the guide hole 11, wherein the guide rod 12 is slidingly connected with the transmission plate 51, so as to limit the stable movement of the transmission plate 51.

[0053] It is worth mentioning here that the transmission plate 51 is arranged in the track 2, the axis of the guide rod 12 is horizontally arranged and perpendicular to the rack 31.

[0054] Further comprising a compression spring 6, wherein the compression spring 6 is sleeved on the guide rod 12, one end of the compression spring 6 abuts against the inner wall of the track 2, the other end of the compression spring 6 abuts against the transmission plate 51, and the compression spring 6 can be used to stably insert the locking teeth 4 into the tooth groove of the rack 31, so as to lock the glass partition plate 3.

[0055] Since the locking teeth 4 are arranged in two groups and are located on the two sides of the glass partition plate 3, in order to make the locking teeth 4 synchronously disengage from the same side of the rack 31, in the embodiment, as shown in Figure 2 and Figure 8 As shown, the workbench top 10 is further provided with a mounting groove 102, wherein the mounting groove 102 is arranged along the axial direction of the guide rod 12, the driving mechanism 5 comprises a transmission rod 52, a hinged plate 53 and a pressing plate 54, wherein the transmission rod 52 is arranged in two groups and is slidingly installed in the mounting groove 102, each transmission rod 52 is fixedly connected with the same side of the transmission plate 51, the pressing plate 54 is horizontally arranged and located directly above the workbench top 10, the two transmission rods 52 are located on the two sides of the pressing plate 54, the hinged plate 53 is arranged in two groups, one end of the hinged plate 53 is hinged to the pressing plate 54, and the other end of the hinged plate 53 is hinged to the transmission rod 52.

[0056] Among them, the hinged plate 53 is arranged obliquely, the two hinged plates 53 are in the shape of "eight", when the pressing plate 54 is pressed downward, the two transmission rods 52 are slidingly moved away from each other through the hinged plate 53, the transmission plate 51 is moved through the transmission rod 52 and the compression spring 6 is extruded, so that the locking teeth 4 can be separated from the rack 31 through the transmission plate 51, and the locking of the glass partition plate 3 is released.

[0057] In order to stably move the pressing plate 54 downward and maintain the horizontal state, in the embodiment, as shown in Figure 8 The bottom wall of the mounting groove 102 is provided with a slot hole 55 extending vertically downward, the bottom wall of the pressing plate 54 is fixedly provided with a slot rod 56 inserted into the slot hole 55, the side wall of the slot rod 56 is slidingly connected with the inner wall of the slot hole 55, thereby maintaining the stable downward movement of the pressing plate 54.

[0058] When the glass partition 3 needs to be lifted upward, the operator directly pushes the glass partition 3 upward with the arm during the work process, when the glass partition 3 needs to be moved downward, the arm of the operator presses the pressing plate 54 on the workbench 10, so that the locking teeth 4 and the rack 31 are out of contact, the locking of the glass partition 3 is released, and the glass partition 3 can move downward under the action of its own gravity, facilitating the adjustment of the position of the glass partition 3.
