[0004] The existing support structure for excavator power distribution cabinets suffers from inconvenient installation and adjustment. Due to the diverse sizes and specifications of power distribution cabinets and the varying structures of excavator bodies, traditional fixing methods often require cumbersome adjustments using specialized tools. This makes it difficult to quickly adapt to the installation needs of power distribution cabinets of different sizes during installation, and the lack of an effective quick-locking mechanism results in low on-site installation efficiency. This is especially inconvenient when operating inside the space-constrained excavator cab. This structural defect directly affects the installation quality and maintenance efficiency of the power distribution cabinet. Utility Model Content

[0015] Beneficial effects
[0016] This utility model provides a support base for an excavator's electrical control cabinet. Compared with the prior art, it has the following advantages:
[0017] 1. By connecting the fixing components at both ends of the positioning component to the load-bearing component, the vertically positioned waist-shaped head is inserted into the waist-shaped fixing hole. By pinching the lever and pushing the pin inward, the waist-shaped head is fully passed through the hole. Then, it is rotated 90 degrees to a horizontal position. At this time, the spring's rebound force pushes the turntable, causing the pin to move forward, so that the waist-shaped head tightly presses against the rear end of the mounting base, forming a lock. This allows the positioning component to fix the distribution cabinet to the load-bearing component through the fixing components. Quick installation and disassembly can be achieved through a simple rotation operation, significantly improving maintenance efficiency. Furthermore, the fit between the waist-shaped head and the waist-shaped fixing hole ensures installation accuracy while allowing for a certain amount of positional adjustment.
[0018] 2. The combination of the third and fourth oblong holes allows the L-shaped bracket and the fixed frame to be adjusted according to the width of the distribution cabinet; the combination of the first and second oblong holes allows the cross frame and the L-shaped bracket to be adjusted according to the length of the distribution cabinet; when the positioning component secures the distribution cabinet to the load-bearing component through the fixing component, the rubber sleeve forms a flexible contact with the metal corner of the front end of the distribution cabinet; the elastic properties of the rubber sleeve effectively absorb and buffer the vibration and impact generated during excavator operation, significantly reducing the mechanical stress transmitted to the distribution cabinet.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a support base for an excavator power distribution cabinet, including a support mechanism 1 for fixing and supporting the power distribution cabinet, the support mechanism 1 including:
[0026] The supporting component 11 includes a mounting base 111 fixed to the excavator body, a mounting plate 112 fixed to the upper end of the mounting base 111, and a plurality of waist-shaped fixing holes 113 arranged in a longitudinal array on both the left and right sides inside the mounting plate 112.
[0027] Positioning component 12 is disposed on the support component 11 and is used to fix the power distribution cabinet on the support component 11;
[0028] The fixing component 13 includes a fixing bracket 131 disposed on the positioning component 12. The fixing bracket 131 has a fourth waist-shaped hole 132 inside. A housing 133 is fixed to the rear end of the fixing bracket 131. A pin 134 is slidably installed through the housing 133. A waist-shaped head 135 is fixed to the rear end of the pin 134 and is adapted to the waist-shaped fixing hole 113. A turntable 136 is rotatably installed on the front end of the pin 134 and is located inside the housing 133. A spring 137 is sleeved on the outside of the pin 134 and is located inside the housing 133.
[0029] In this embodiment, after the load-bearing component 11 is fixed to the excavator body, the power distribution cabinet is placed on the mounting base 111 with its rear end fitting against the mounting plate 112. After adjusting the length and width of the positioning component 12 to match the power distribution cabinet, the fixing components 13 at both ends of the positioning component 12 are connected to the load-bearing component 11. The vertical waist-shaped head 135 is inserted into the waist-shaped fixing hole 113. By pinching the button rod 139, the pin rod 134 is pushed inward to make the waist-shaped head 135 completely pass through the hole. Then, it is rotated 90 degrees to a horizontal position. At this time, the rebound force of the spring 137 pushes the turntable 136 to move the pin rod 134 forward, so that the waist-shaped head 135 tightly presses against the rear end of the mounting base 111 to form a lock. This allows the positioning component 12 to fix the power distribution cabinet to the load-bearing component 11 through the fixing components 13. Quick installation and disassembly can be achieved through a simple rotation operation, which significantly improves maintenance efficiency. Furthermore, the cooperation between the waist-shaped head 135 and the waist-shaped fixing hole 113 ensures installation accuracy while allowing a certain amount of position adjustment margin.
[0030] Specifically, the fixing component 13 also includes a groove 138 opened at the front end of the pin 134, and a toggle 139 is fixed inside the groove 138, and the toggle 139 is parallel to the waist-shaped head 135.
[0031] In this embodiment, by setting a groove 138 at the front end of the pin 134 and fixing a toggle 139 parallel to it, the locking state is visualized intuitively and operated conveniently.
[0032] Specifically, the positioning component 12 includes a crossbeam 121 located in front of the mounting base 111. Both ends of the crossbeam 121 are equipped with L-shaped brackets 123. The L-shaped brackets 123 have a third oblong hole 125 inside their side ends. The L-shaped brackets 123 are fixed to the fixing bracket 131 by bolts through the third oblong hole 125 and the fourth oblong hole 132.
[0033] In this embodiment, the cooperation of the third oblong hole 125 and the fourth oblong hole 132 allows the L-shaped bracket 123 and the fixed bracket 131 to be adapted and adjusted according to the width of the power distribution cabinet.
[0034] Specifically, the positioning component 12 also includes a first waist-shaped hole 122 opened inside the crossbeam 121, and a second waist-shaped hole 124 opened inside the front end of the L-shaped bracket 123. The crossbeam 121 is fixed to the L-shaped bracket 123 by the first waist-shaped hole 122 and the second waist-shaped hole 124 through the bolt.
[0035] In this embodiment, the first waist-shaped hole 122 and the second waist-shaped hole 124 are matched to allow the crossbar 121 and the L-shaped bracket 123 to be adapted and adjusted according to the length of the power distribution cabinet.
[0036] Specifically, the positioning component 12 also includes a rubber sleeve 126 that covers and fixes the corners of the L-shaped bracket 123.
[0037] In this embodiment, when the positioning component 12 fastens the power distribution cabinet to the bearing component 11 through the fixing component 13, the rubber sleeve 126 forms a flexible contact with the metal corner of the front end of the power distribution cabinet; the elastic characteristics of the rubber sleeve 126 effectively absorb and buffer the vibration impact generated during the excavator operation, significantly reducing the mechanical stress transmitted to the power distribution cabinet.
[0038] Specifically, the support component 11 also includes mounting holes 114 formed at the four corners inside the mounting base 111.
[0039] In this embodiment, the mounting base 111 is fixed to the excavator body with bolts through the mounting hole 114. Alternatively, the mounting base 111 can also be fixed to the excavator body with bolts through the waist-shaped fixing hole 113. The two fixing methods are suitable for the installation requirements of different models of excavators.
[0040] The working principle and usage process of this utility model are as follows: First, after fixing the bearing component 11 to the excavator body, place the power distribution cabinet on the mounting base 111, with its rear end fitting against the mounting plate 112. Then, adjust the length and width of the positioning component 12 to match the power distribution cabinet. Next, connect the fixing components 13 at both ends of the positioning component 12 to the bearing component 11. After inserting the vertical waist-shaped head 135 into the waist-shaped fixing hole 113, push the pin 134 inward by pinching the button rod 139 to make the waist-shaped head 135 completely pass through the hole. Then rotate 90 degrees to a horizontal position. At this time, the rebound force of the spring 137 pushes the turntable 136 to move the pin 134 forward, so that the waist-shaped head 135 tightly presses against the rear end of the mounting base 111 to form a lock. This allows the positioning component 12 to fix the distribution cabinet on the bearing component 11 through the fixing component 13. Quick installation and disassembly can be achieved through a simple rotation operation, which significantly improves maintenance efficiency. In addition, the cooperation between the waist-shaped head 135 and the waist-shaped fixing hole 113 ensures the installation accuracy while allowing a certain position adjustment margin.
