Description

Technical Field

[0001] This utility model relates to the field of protective plate technology, and in particular to a bottom protective plate. Background Technology

[0002] The excavator water tank serves the functions of water storage and heat dissipation. Its main function is to absorb and remove heat from the engine and hydraulic oil tank through circulating water, ensuring the normal operation of the excavator. During the assembly of the excavator water tank, some surfaces will be exposed, which requires protection. For example, the bottom of the excavator water tank is protected by a bottom guard plate.

[0003] Traditional excavator water tank bottom guards are installed by first attaching the guard to the surface of the water tank, then inserting four bolts through the mounting holes at the four corners of the guard, and finally threading the bolts onto the water tank to fix the guard in place. This prevents the bottom of the excavator water tank from being damaged or broken by objects like gravel. However, in actual use, it has been found that the bottom guard does not have a proper contact connection with the excavator during assembly. This leaves the water tank with its bottom suspended, reducing its stability and thus diminishing its practicality and protective effect. Utility Model Content

[0004] The technical problem this utility model aims to solve is that when the bottom guard plate is assembled and used, there is no contact connection between it and the excavator. At this time, the water tank will be suspended at the bottom, which will reduce the stability of the water tank. The practicality of the bottom guard plate will also be somewhat defective, reducing the protective effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a bottom guard plate, including a guard plate body, a support device, and a connecting device. Mounting holes are respectively opened at the four corners of the guard plate body. The support device is installed and fixed to the surface of the guard plate body by means of the connecting device. The support device includes a mounting plate. Support frames are rotatably connected to both sides of the surface of the mounting plate. A connecting rod is fixed to one side of the inner wall of the support frame that is close to each other. An installation tube is rotatably connected to the arc surface of the connecting rod. A sliding groove is opened on the side of the mounting plate away from the guard plate body. Two sliders are slidably connected to the inner wall of the sliding groove. Support rods are rotatably connected to the inner walls of the two sliders. The support rods are fixedly connected to the arc surface of the installation tube. A positioning plate is snapped onto the surface of the two sliders. A screw is inserted through the surface of the positioning plate and slidably connected to the inner wall of the sliding groove.

[0006] The effects achieved by the above components are as follows: when in use, the guard plate body can form a certain connection with the excavator, which can better protect the water tank, prevent the water tank from being suspended in the air, improve the stability of the water tank, and further improve the functionality and practicality of the guard plate body.

[0007] Preferably, springs are fixedly connected to one side surface of each of the two sliders, and the other end of the springs is fixedly connected to the inner wall of the groove.

[0008] The effect achieved by the above components is as follows: by setting the spring, when the guard plate body is installed at the bottom of the water tank, the slider will slide on the inner wall of the groove under the elastic force of the spring, so that the support frame can quickly contact the surface of the excavator, which facilitates the subsequent positioning.

[0009] Preferably, an operating block is fixedly connected to the surface of the screw, and the surface of the operating block is provided with a plurality of anti-slip protrusions.

[0010] The effect achieved by the above components is that the operation block makes the screw more convenient and quick to use, thereby enabling the screw to connect with the inner wall of the chute more quickly and the support frame to contact and press against the surface of the excavator more quickly.

[0011] Preferably, the two ends of the support frame are respectively fixedly connected with reinforcing pads, and the reinforcing pads are rubber pads.

[0012] The effect achieved by the above components is that, by setting up the reinforcing pad, the friction force between the support frame and the surface of the excavator is further increased, thus making it more stable and further improving the performance of the support device.

[0013] Preferably, a washer is fitted on the arc surface of the screw, the washer being a metal washer, and the washer abuts against the surface of the positioning plate.

[0014] The effect achieved by the above components is that, through the setting of the washer, the screw can be stably attached to the surface of the positioning plate during use, thereby the positioning plate can more stably fix the position of the slider.

[0015] Preferably, the connecting device includes two mounting shafts, which are fixedly connected to the surface of the guard plate body, and connecting plates are rotatably connected to the arc surfaces of the two mounting shafts. Bolts are inserted through the surface of the connecting plates, and connecting grooves are respectively opened on both sides of the surface of the mounting plates. The connecting plates are engaged with the inner walls of the connecting grooves, and the bolts are threaded to the inner walls of the connecting grooves.

[0016] The effects achieved by the above components are: the support device is more convenient and quick to use, thus better supporting and protecting the water tank on one side of the protective plate body, and also improving the ease of use of the support device.

[0017] Preferably, a connecting rope is fixedly connected to the surface of the bolt, and the other end of the connecting rope is fixedly connected to the surface of the connecting plate.

[0018] The effect achieved by the above components is that the bolts are easier to handle during use by setting up the connecting rope, which in turn makes the installation and fixing of the support device more convenient and further improves the ease of use of the connecting device.

[0019] Preferably, torsion springs are respectively fitted on the arc surfaces at both ends of the two mounting shafts, and the two ends of the torsion springs are respectively fixedly connected to the surfaces of the mounting shaft and the connecting plate.

[0020] The effect achieved by the above components is as follows: by setting the torsion spring, when the mounting plate is disassembled, after the rotating bolt separates from the connecting groove, the connecting plate will rotate under the torsional force of the torsion spring, thereby facilitating the removal of the mounting plate and further improving the functionality of the connecting device.

[0021] The beneficial effects of this utility model are:

[0022] When in use, the protective plate body of this utility model can form a certain connection with the excavator, which can better protect the water tank, prevent the water tank from being suspended in the air, improve the stability of the water tank, and further improve the functionality and practicality of the protective plate body.

[0031] Figure 1 The excavator water tank bottom guard plate shown includes a guard plate body 1, a support device 3 and a connecting device 4. Mounting holes 2 are respectively opened at the four corners of the guard plate body 1. The support device 3 is installed and fixed on the surface of the guard plate body 1 by means of the connecting device 4.

[0032] Figure 1 , Figure 2 and Figure 3The support device 3 shown includes a mounting plate 31. Support frames 32 are rotatably connected to both sides of the surface of the mounting plate 31. Connecting rods 33 are fixed to the inner walls of the support frames 32 on their closest sides. Mounting tubes 34 are rotatably connected to the arc surface of the connecting rods 33. A groove 36 is formed on the surface of the mounting plate 31 away from the protective plate body 1. Two sliders 37 are slidably connected to the inner wall of the groove 36. Support rods 35 are rotatably connected to the inner walls of the two sliders 37. The support rods 35 are fixedly connected to the arc surface of the mounting tube 34. A positioning plate 38 is snapped onto the surface of the two sliders 37. A screw 39 is inserted through the surface of the positioning plate 38 and slidably connected to the inner wall of the groove 36. When the protective plate body 1 protects the bottom of the water tank, the protective plate body 1 is first fixed to the bottom of the water tank using screws and mounting holes 2 on its surface. Then, the two sliders 37 on the inner wall of the groove 36 on the surface of the mounting plate 31 are slidably connected. The slider 37 pulls the support rod 35 on the slider 37, causing the mounting tube 34, which is fixedly connected to one end of the support rod 35, to rotate on the arc surface of the connecting rod 33 on the surface of the support frame 32. During the rotation, the support frame 32 rotates on the surface of the mounting plate 31 until both ends of the support frame 32 contact and press against the surface of the excavator. Then, the two ends of the positioning plate 38 are respectively snapped into the inner walls of the two sliders 37. The screw 39 is then inserted through the surface of the positioning plate 38, so that the screw 39 is threadedly connected to the inner wall of the groove 36 until the nut of the screw 39 contacts and presses against the surface of the positioning plate 38, thus fixing the position of the support frame 32. At this time, when the guard plate body 1 is in use, it can form a certain connection with the excavator, which can better protect the water tank, prevent the water tank from being suspended, improve the stability of the water tank, and further improve the functionality and practicality of the guard plate body 1.

[0033] Figure 1 , Figure 2 and Figure 3 Two sliders 37 are shown, each with a spring 310 fixedly connected to one side surface. The other end of the spring 310 is fixedly connected to the inner wall of the groove 36. With the spring 310, when the guard plate body 1 is installed at the bottom of the water tank, the slider 37 will slide on the inner wall of the groove 36 under the elastic force of the spring 310, so that the support frame 32 can quickly contact the surface of the excavator, which is convenient for subsequent positioning. The screw 39 is fixedly connected to the surface of the screw 39. The surface of the operation block 312 is provided with several anti-slip protrusions. With the operation block 312, the screw 39 is more convenient and quick to use, so that the screw 39 can connect to the inner wall of the groove 36 more quickly, and the support frame 32 can contact and press against the surface of the excavator more quickly.

[0034] Figure 1 , Figure 2 and Figure 3The support frame 32 shown has reinforcing pads 311 fixedly connected to both ends of its surface. The reinforcing pads 311 are rubber pads. By setting the reinforcing pads 311, the friction force of the support frame 32 pressing against the surface of the excavator is further increased, thus making it more stable and further improving the performance of the support device 3. A washer 313 is fitted on the arc surface of the screw 39. The washer 313 is a metal pad and abuts against the surface of the positioning plate 38. By setting the washer 313, the screw 39 can be stably attached to the surface of the positioning plate 38 during use, so that the positioning plate 38 can more stably fix the position of the slider 37.

[0035] Figure 1 and Figure 4 The connecting device 4 shown includes two mounting shafts 41, which are fixedly connected to the surface of the protective plate body 1. Connecting plates 42 are rotatably connected to the arc surfaces of the two mounting shafts 41. Bolts 43 are inserted through the surface of the connecting plates 42. Connecting grooves 44 are respectively opened on both sides of the surface of the mounting plate 31. The connecting plates 42 are engaged with the inner walls of the connecting grooves 44. The bolts 43 are threadedly connected to the inner walls of the connecting grooves 44. When the support device 3 is installed on the protective plate body 1, the mounting plate 31 is first attached to the surface of the protective plate body 1. Then, the connecting plates 42 on the mounting shafts 41 are rotated so that the connecting plates 42 are engaged into the connecting grooves 44 on the surface of the mounting plate 31. Then, the bolts 43 are inserted through the surface of the connecting plates 42 until the bolts 43 are threadedly connected to the inner walls of the connecting grooves 44 of the mounting plate 31. At this time, the support device 3 is more convenient and quick to use, thus better supporting and protecting the water tank on one side of the protective plate body 1, and also improving the ease of use of the support device 3.

[0036] Figure 1 and Figure 4 A connecting rope 45 is fixedly connected to the surface of the bolt 43 shown. The other end of the connecting rope 45 is fixedly connected to the surface of the connecting plate 42. The setting of the connecting rope 45 makes it easier to pick up the bolt 43 during use, thereby making it easier to install and fix the support device 3, and further improving the ease of use of the connecting device 4. Torsion springs 46 are respectively sleeved on the arc surfaces at both ends of the two mounting shafts 41. The two ends of the torsion springs 46 are fixedly connected to the surfaces of the mounting shafts 41 and the connecting plate 42, respectively. With the setting of the torsion springs 46, when the mounting plate 31 is disassembled, after the bolt 43 is separated from the connecting groove 44, the connecting plate 42 will rotate under the torsional force of the torsion springs 46, thereby making it easier to remove the mounting plate 31, and further improving the functionality of the connecting device 4.

[0037] Working principle: When the protective plate body 1 protects the bottom of the water tank, it is first fixed to the bottom of the water tank with screws and mounting holes 2 on the surface. Then, the two sliders 37 on the inner wall of the sliding groove 36 on the surface of the sliding mounting plate 31 are pulled, thereby pulling the support rod 35 on the slider 37. This causes the mounting tube 34, which is fixedly connected to one end of the support rod 35, to rotate on the arc surface of the connecting rod 33 on the surface of the support frame 32. During the rotation, the support frame 32 rotates on the surface of the mounting plate 31 until both ends of the support frame 32 contact and press against the surface of the excavator. Then, the two ends of the positioning plate 38 are... The screw 39 is inserted into the inner wall of the two sliders 37 respectively, and then the screw 39 is passed through the surface of the positioning plate 38. The operating block 312 fixedly connected to the screw 39 is rotated to make the screw 39 threadedly connected to the inner wall of the slide groove 36 until the nut of the screw 39 contacts and presses against the surface of the positioning plate 38, so that the position of the support frame 32 is fixed. At this time, when the guard plate body 1 is in use, it can form a certain connection with the excavator, which can better protect the water tank, prevent the water tank from being suspended, improve the stability of the water tank, and further improve the functionality and practicality of the guard plate body 1.

[0038] When the support device 3 is installed on the protective plate body 1, the mounting plate 31 is first attached to the surface of the protective plate body 1. Then, the connecting plate 42 on the mounting shaft 41 is rotated so that the connecting plate 42 is engaged in the connecting groove 44 on the surface of the mounting plate 31. Then, the bolt 43 fixedly connected to the connecting rope 45 is passed through the surface of the connecting plate 42 until the bolt 43 is threaded into the inner wall of the connecting groove 44 of the mounting plate 31. At this time, the support device 3 is more convenient and quick to use, thus better supporting and protecting the water tank on one side of the protective plate body 1, and also improving the ease of use of the support device 3.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
