Description

Technical Field

[0001] This utility model relates to the field of engineering vehicle control box technology, specifically an engineering vehicle control box that is easy to maintain. Background Technology

[0002] Nowadays, all kinds of large machinery are widely used, which liberates manpower and improves productivity. Various large machinery adopts hydraulic or electric control methods. In order to allow operators to control the hydraulic system and the electric system better and more conveniently, designers have designed the handrail box.

[0003] Currently, the control box of the engineering vehicle is located on the right side of the driver's seat. When maintenance is required, the staff can only remove the entire outer shell of the control box to carry out internal maintenance operations. This is time-consuming and laborious. In addition, if the box is not aligned properly after maintenance, it can easily cause unstable installation. Therefore, we propose an engineering vehicle control box that is easier to maintain. Summary of the Invention

[0004] The purpose of this invention is to provide an easy-to-maintain control box for engineering vehicles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an easy-to-maintain engineering vehicle control box, comprising a control box body, an openable box door provided on the back of the control box body, and a limiting component for restricting the box door provided on the back of the control box body. The limiting components include: A baffle is used to block and restrict the door of the container, preventing it from being opened. The fixed base is used to support the baffle and, together with the spiral spring, applies a rotational force to the baffle. The lever is used to engage with the slot on the side of the baffle near the control box body to restrict the baffle. Connecting plate, used to control the lever via the support rod.

[0006] Preferably, the fixed base is fixed to the back of the control box body, the baffle is rotatably mounted on the side of the fixed base away from the control box body, a spiral spring is fixed to the outer wall of the baffle, the end of the spiral spring away from the baffle is fixed to the fixed base, the locking rod passes through the fixed base, a fixing rod is fixed to the inner wall of the fixed base, the fixing rod passes through the locking rod and is slidably connected to the locking rod, a support spring is fixed to the end of the locking rod near the fixing rod, the end of the support spring away from the locking rod is fixed to the inner wall of the fixed base, the connecting plate passes through the side of the fixed base near the box door and is slidably connected to the fixed base, a support rod is hinged to the end of the connecting plate away from the box door, and the support rod is hinged to the end of the connecting plate away from the connecting plate. The end is hinged to the lever. A contact plate is fixed on the side of the door near the fixed base. A slot is opened on the side of the baffle near the control box body. When the operator needs to open the door to maintain the inside of the control box body, he only needs to manually rotate the baffle so that the baffle no longer abuts against the surface of the door. After the baffle is rotated to a vertical position, the door opens, and the door opens along with the contact plate. The inclined surface of the contact plate no longer abuts against the inclined surface of the connecting plate, so the connecting plate is no longer restricted. At this time, under the action of the support spring, the lever can spring up and insert into the slot of the baffle to restrict the baffle. The overall maintenance is convenient and does not require the operator to remove the entire outer shell of the control box body, which effectively improves the overall maintenance efficiency.

[0007] Preferably, a fixing plate is fixed to the front of the box door, and a hinge seat is fixed to the back of the control box body. The box door is hinged to the hinge seat. A spiral spring II is fixed to the outer wall of the box door. The end of the spiral spring II away from the box door is fixed to the hinge seat. Through the fixing plate, the fixing plate can support the baffle, so that the baffle can only rotate to a state perpendicular to the fixing seat. The baffle can stably restrict the box door. When the box door is no longer restricted, the box door can rotate and open under the action of the spiral spring II. This can prevent the box door from being accidentally closed during maintenance, which could cause the staff to be trapped.

[0008] Compared with the prior art, this utility model provides an easy-to-maintain control box for engineering vehicles, which has the following advantages: 1. This easy-to-maintain engineering vehicle control box, through its set limiting components and door, allows operators to easily open the door for maintenance when needed. They simply need to manually rotate the baffle so that it no longer contacts the door surface, allowing the door to open automatically. The door opens along with the baffle, and the inclined surface of the baffle no longer contacts the inclined surface of the connecting plate, thus freeing the connecting plate from restriction. At this point, under the action of the support spring, the locking rod springs up and inserts into the baffle's slot, restricting the baffle. Overall maintenance is convenient, eliminating the need for operators to completely disassemble the control box's outer shell, effectively improving overall maintenance efficiency.

[0009] 2. This easy-to-maintain engineering vehicle control box, through the setting of a fixing plate, can support the baffle, so that the baffle can only rotate to a state perpendicular to the fixing seat. The baffle can stably restrict the box door. When the box door is no longer restricted, the box door can be rotated and opened under the action of the spiral spring. This can prevent the box door from being accidentally closed during maintenance, which could cause workers to be trapped. Attached Figure Description

[0012] like Figures 1-6 As shown, this utility model provides a technical solution: an easy-to-maintain engineering vehicle control box, including a control box body 1, an openable box door 2 provided on the back of the control box body 1, and a limiting component 3 for restricting the box door 2 provided on the back of the control box body 1, the limiting component 3 including: a baffle 31, a fixing seat 32, a spiral spring 33, a locking rod 34, a connecting plate 35, a support rod 36, a fixing rod 37, a support spring 38, and a contact plate 39.

[0013] The mounting base 32 is fixed to the back of the control box body 1. The baffle 31 is rotatably mounted on the side of the mounting base 32 away from the control box body 1. A spiral spring 33 is fixed to the outer wall of the baffle 31. The end of the spiral spring 33 away from the baffle 31 is fixed to the mounting base 32. The locking rod 34 passes through the mounting base 32. A fixing rod 37 is fixed to the inner wall of the mounting base 32. The fixing rod 37 passes through the locking rod 34 and is slidably connected to the locking rod 34. A support spring 38 is fixed to the end of the locking rod 34 near the fixing rod 37. The end of the support spring 38 away from the locking rod 34 is fixed to the mounting base 32. On the inner wall of the fixed seat 32, a connecting plate 35 passes through the side of the fixed seat 32 near the door 2, and the connecting plate 35 is slidably connected to the fixed seat 32. A support rod 36 is hinged to the end of the connecting plate 35 away from the door 2, and the end of the support rod 36 away from the connecting plate 35 is hinged to a locking rod 34. An abutment plate 39 is fixed to the side of the door 2 near the fixed seat 32. A slot is provided on the side of the baffle 31 near the control box body 1. When the operator needs to open the door 2 to maintain the inside of the control box body 1, he only needs to manually rotate the baffle 31 so that the baffle 31 is no longer in contact with the door 2. The surface of the baffle plate 39 is in contact with the baffle plate 35 until the baffle plate 31 rotates to a vertical position. Then, the door 2 opens, along with the baffle plate 39. The inclined surface of the baffle plate 39 no longer contacts the inclined surface of the connecting plate 35, thus the connecting plate 35 is no longer restricted. At this point, under the action of the support spring 38, the locking rod 34 can spring up and insert into the slot of the baffle plate 31, restricting the baffle plate 31. Overall maintenance is convenient, eliminating the need for personnel to completely disassemble the outer shell of the control box body 1, effectively improving overall maintenance efficiency. After maintenance, personnel only need to manually close the door 2. At this time, the door 2 rotates together with the abutment plate 39 until the inclined surface of the abutment plate 39 abuts against the inclined surface of the connecting plate 35. Then, the connecting plate 35 can be pushed to move into the fixed seat 32. The connecting plate 35 can then push the locking rod 34 to move away from the baffle 31 through the support rod 36. The locking rod 34 can then exit from the slot of the baffle 31, releasing the restriction on the baffle 31. At this time, the baffle 31 can rotate under the action of the spiral spring 33. The baffle 31 can then block the surface of the door 2 again, restricting the door 2, thereby closing the door 2.

[0014] A fixing plate 4 is fixed to the front of the box door 2, and a hinge seat 5 is fixed to the back of the control box body 1. The box door 2 is hinged to the hinge seat 5. A spiral spring 6 is fixed to the outer wall of the box door 2. The end of the spiral spring 6 away from the box door 2 is fixed to the hinge seat 5. Through the fixing plate 4, the fixing plate 4 can support the baffle 31, so that the baffle 31 can only rotate to a state perpendicular to the fixing seat 32. The baffle 31 can stably restrict the box door 2. When the box door 2 is no longer restricted, the box door 2 can rotate and open under the action of the spiral spring 6. This can prevent the box door 2 from being accidentally closed during maintenance, which could cause the staff to be trapped.

[0015] In this utility model, when the operator needs to open the door 2 to maintain the inside of the control box body 1, they only need to manually rotate the baffle 31 so that the baffle 31 no longer abuts against the surface of the door 2. After the baffle 31 is rotated to a vertical position, the door 2 is no longer restricted and can be rotated and opened under the action of the spiral spring 6. The door 2 opens together with the abutment plate 39. The inclined surface of the abutment plate 39 no longer abuts against the inclined surface of the connecting plate 35, so the connecting plate 35 is no longer restricted. At this time, under the action of the support spring 38, the locking rod 34 can spring up and insert into the slot of the baffle 31 to restrict the baffle 31. The overall maintenance is convenient and does not require the operator to completely remove the outer shell of the control box body 1, which effectively improves the overall maintenance efficiency.

[0016] After maintenance, the staff only needs to manually close the box door 2. At this time, the box door 2 rotates together with the abutment plate 39 until the inclined surface of the abutment plate 39 abuts against the inclined surface of the connecting plate 35. Then, the connecting plate 35 can be pushed to move into the fixed seat 32. The connecting plate 35 can then push the locking rod 34 to move away from the baffle 31 through the support rod 36. The locking rod 34 can then exit from the slot of the baffle 31, releasing the restriction on the baffle 31. At this time, the baffle 31 can rotate under the action of the spiral spring 33. The baffle 31 can then block the surface of the box door 2 again, restricting the box door 2, thereby closing the box door 2.

[0017] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
