Description

Technical Field

[0001] This utility model relates to the field of damper adjustment technology, and more specifically to a multi-mode damper adjustment device for excavators. Background Technology

[0002] Excavators typically have air conditioning vents on their center console, and these vents are equipped with air deflectors. Operators can control the airflow by moving the deflectors. Excavators usually work outdoors, facing harsh environments such as dust and mud. These impurities can easily contaminate the air deflectors. To ensure clean airflow, the air deflectors usually need to be removed from the vents periodically for cleaning.

[0003] Existing excavator air conditioner air deflectors generally utilize the elastic deformation properties of plastic to be fixed at the air conditioner outlet. However, excavator air deflectors are frequently disassembled and reassembled. After repeated disassembly and reassembly, the plastic is prone to wear and aging, which can lead to loosening of the installation and, in severe cases, breakage. Utility Model Content

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The multi-mode damper adjustment device for excavators involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This utility model provides a multi-mode damper adjustment device for excavators, including an extension groove 1, which is opened on the central control panel of the excavator and connected to the air conditioning outlet. A limit ring 3 is fixedly connected to the wall of the extension groove 1. A guide plate 2 is provided on the front side of the limit ring 3, and a positioning component 4 and a control component 5 are provided on the rear side of the limit ring 3. The positioning component 4 is used to fix the guide plate 2 to the front side of the limit ring 3, and the control component 5 is used to release the fixation of the guide plate 2.

[0022] Furthermore, two positioning components 4 are symmetrically arranged. Positioning components 4 include a receiving strip 41, an L-shaped rod 42, a support frame 44, and a sleeve 47. The support frame 44 is fixedly installed on the rear side of the limiting ring 3, and a guide rod 45 is fixedly connected to the support frame 44. A moving frame 43 is fixedly connected to the side of the receiving strip 41 away from the middle of the limiting ring 3. The moving frame 43 is sleeved on the surface of the guide rod 45, and the moving frame 43 and the guide rod 45 form a sliding guide fit along the axis of the guide rod 45. A compression spring 46 is sleeved on the surface of the guide rod 45. One end of the compression spring 46 is fixedly connected to the side of the moving frame 43 away from the receiving strip 41, and the other end is fixedly connected to the side of the support frame 44 facing the moving frame 43. The elastic force of the compression spring 46... The motion frame 43 can be driven to move away from the support frame 44. One end of the L-shaped rod 42 is fixedly connected to the top of the receiving strip 41, and the other end is fixedly connected to the trigger plate 421. The receiving strip 41 has a positioning groove 411 on one side facing the middle of the limiting ring 3. The receiving strip 41 is also provided with a guide arc surface 412. The sleeve 47 is fixedly installed on the rear side of the limiting ring 3. The L-shaped rod 42 is sleeved inside the sleeve 47. The sleeve 47 plays the role of supporting the L-shaped rod 42 and ensuring its stability. The rear side of the air guide plate 2 is fixedly connected to the fixing frame 21. There are two symmetrically arranged fixing frames 21. The fixing frame 21 is fixedly connected to the positioning rod 22. The positioning rod 22 matches the positioning groove 411. The top of the air guide plate 2 has an avoidance opening 23.

[0023] Furthermore, the control component 5 includes a rotating rod 51, which is rotatably mounted on the limiting ring 3. One end of the rotating rod 51 extends to the front side of the limiting ring 3, and the other end extends to the rear side of the limiting ring 3. A rotating handle 53 is fixedly connected to one end of the rotating rod 51, and the rotating handle 53 is located inside the clearance opening 23. A rotating block 52 is fixedly connected to the other end of the rotating rod 51, and the rotating block 52 is located between the two trigger plates 421. An eccentric block 521 is fixedly connected to the surface of the rotating block 52, and two eccentric blocks 521 are symmetrically arranged. The eccentric block 521 is matched with the trigger plate 421. The operator can turn the rotating handle 53 by hand to make the rotating rod 51 rotate around its own axis. While the rotating rod 51 is rotating, it squeezes the trigger plate 421 through the eccentric block 521, so that the two trigger plates 421 move in opposite directions. A coil spring 54 is sleeved on the surface of the rotating rod 51. The coil spring 54 plays a reset role. When the operator turns the rotating handle 53 and releases it, the elastic force of the coil spring 54 can drive the rotating rod 51 back to the initial position.

[0024] The working principle of this utility model is as follows: The operator inserts the air guide plate 2 into the extension slot 1 on the central control panel of the excavator. During this process, the positioning rod 22 first contacts the guide arc surface 412. Under the compression of the positioning rod 22, the receiving strip 41 and the moving frame 43 move together along the guide rod 45 towards the support frame 44. The compression spring 46 contracts and increases its elasticity under the compression of the moving frame 43. When the air guide plate 2 and the front side of the limiting ring 3 come into contact with each other, the positioning rod 22 separates from the guide arc surface 412. The elasticity of the compression spring 46 is released and drives the receiving strip 41 to move away from the support frame 44. The positioning rod 22 enters the positioning slot 411. The positioning rod 22 and the positioning slot 411 cooperate with each other to fix the position of the air guide plate 2.

[0025] When the air guide plate 2 needs to be disassembled, the operator manually turns the rotating handle 53 to make the rotating rod 51 rotate around its own axis. The rotating rod 51 rotates and drives the rotating block 52 to rotate synchronously around the axis of the rotating rod 51. At the same time, the rotating block 52 rotates and squeezes the trigger plate 421 through the eccentric block 521, causing the two L-shaped rods 42 to move in opposite directions. The movement of the L-shaped rods 42 drives the two receiving strips 41 to move synchronously in opposite directions, so that the positioning rod 22 is disengaged from the positioning groove 411. At this time, the operator can take the air guide plate 2 out of the extension groove 1.
