[0024] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0025] Embodiment 1

[0026] As Figure 1 、 Figure 2 shown, in this example, the external trachea lifting and adjusting device includes a nozzle mechanism 2 and a bracket 1. The nozzle mechanism 2 is installed on the bracket 1. The bracket adopts a frame structure. Specifically, the nozzle mechanism 2 is installed at the frame opening of the rectangular frame, and the screw-type lifting mechanism 3 and the guiding mechanism 4 are installed on the side of the frame. When in use, the guiding mechanism 4 guides the lifting of the bracket 1. When in use, if the material passes below the frame opening, it is processed by the nozzle mechanism, and the layout is more reasonable. Of course, the installation position of the lifting mechanism can be selected according to requirements, such as being installed above, below, etc. in the middle of the bracket. The corresponding bracket can adopt a non-frame configuration, such as a plate shape, etc.

[0027] In this utility model, the lifting mechanism 3 includes a lead screw 31 and a nut seat 32 that cooperates with the lead screw. The nut seat 32 is longitudinally fixed on the side of the frame of the bracket 1 (such as Figure 1 、 Figure 2 shown on the right side) or can be directly integrally formed, etc. The longitudinal lead screw 31 passes through and meshes with the nut seat 32. The guiding mechanism 4 is installed at the four corners of the frame of the bracket 1. By rotating the lead screw, the nut seat drives the bracket to move up and down under the guidance of the guiding mechanism. The lead screw can be selected as a self-locking type according to requirements to stably stay at the required position.

[0028] For the convenience of installation, in this example, a first fixing seat 5 is added. The first fixing seat 5 is installed at the end of the corresponding lead screw 31 above and below the bracket 1. For example, the tail end of the lead screw 31 is connected and rotatably fitted in the hole of the corresponding first fixing seat 5, and the head end of the lead screw 31 passes through and rotatably fits in the hole of the corresponding first fixing seat 5. The first fixing seat is used to receive the installation surface. Installation holes (such as through holes, threaded holes, etc.) can be pre-formed on the seat body of the first fixing seat, or bolts, etc. can be pre-installed in advance. The orientation of the installation holes can be selected according to requirements, and the specific shape of the first fixing seat can be selected according to requirements.

[0029] For the convenience of driving the lead screw to rotate, a driving mechanism is added in this example, such as Figure 1As shown in the figure, the handwheel 10 is used as the driving mechanism. The handwheel 10 is installed at the head end of the lead screw 31. By holding the handle of the handwheel and turning it, the lead screw can be driven to rotate synchronously, thereby lifting the bracket.

[0030] For the guiding mechanism, as Figure 1 shown, the guiding mechanism 4 includes a guiding rod 42 and a matching guiding cylinder 41. The guiding cylinder 41 is fixed at the four corners of the frame of the bracket 1 and can be integrally formed. The guiding rod 42 passes through the guiding cylinder 41. During the lifting process of the bracket, the guiding cylinder and the guiding rod cooperate to guide the movement of the bracket.

[0031] For the convenience of installation, in this example, fixing seats II 6 are installed at the ends of the guiding rods 42 above and below the bracket 1. The fixing seats II are docked with the surface to be installed. Installation holes (such as through holes, threaded holes, etc.) can be pre-formed on the seat body of the fixing seat II 6, or bolts, etc. can be pre-installed. The orientation of the installation holes can be selected according to requirements, and the specific shape of the fixing seat II can be selected according to requirements.

[0032] In this example, the nozzle mechanism includes a pipe body 21 and a nozzle 22. As Figure 1 、 Figure 2 shown, the pipe body 21 is horizontally arranged. A number of air outlet nozzles are formed at intervals along the length direction at the bottom surface of the pipe body 21, and nozzles 22 are installed at the air outlet nozzles. An air inlet nozzle 23 is installed at the middle position of the top surface of the pipe body 21. The number of air outlet nozzles can be selected according to requirements. The air inlet nozzle is connected to an external gas conveying mechanism and is ejected through the nozzle, such as for cleaning or cutting, etc.

[0033] In addition, for the convenience of docking the nozzle mechanism with the bracket, a fixing mechanism is added in this example. The fixing mechanism is installed at the end of the pipe body 21. The fixing mechanism includes a connecting plate 7, a bolt 8, and a nut 9. The bottom of the plate-shaped connecting plate is fixed to the pipe body. A reinforcing plate can be added between the connecting plate and the pipe body according to requirements. A bolt 8 is horizontally fixed at the head end of the connecting plate 7. A groove is formed at the top surface of the side of the frame of the bracket 1. The bolt 8 passes through the groove, and nuts 9 are installed on both bolts on both sides of the groove. During installation, after assembling the pipe body, nozzle, connecting plate, nut, etc., place the nozzle mechanism above the bracket and align the bolt with the groove opening, lower it so that part of the bolt is in the groove, and turn the nuts towards each other. The two nuts clamp the frame at the groove to fix it.

[0034] Embodiment 2

[0035] The difference from Embodiment 1 is that as Figure 3As shown, in this example, the driving mechanism is the motor 11. The output end of the motor 11 is connected to the head end of the lead screw 31, such as through a coupling. The motor 11 is fixed on the mounting seat 12. For example, the mounting seat is of a frame type, and the motor 11 is located inside the cavity of the mounting seat 12. The first fixing seat 5 is fixed to the mounting seat 12 to dock the mounting seat with the surface to be mounted, etc. For example, mounting holes are pre-formed on the seat body of the mounting seat, or bolts are pre-installed, etc., so that the motor drives the lead screw to rotate. In addition, a displacement sensor, etc. can be added. For example, a displacement sensor is fixed on the mounting seat, or a displacement sensor is installed on the bracket. The displacement sensor and the motor are both connected to the control end. After lifting to the predetermined position, the control end receives the signal of the displacement sensor and controls the motor to stop.

[0036] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
