Description

Technical Field

[0001] This utility model relates to the field of engine maintenance technology, and in particular to a portable engine cylinder carbon deposit visualization device. Background Technology

[0002] In car maintenance, engine maintenance is necessary. The condition of carbon deposits inside the engine cylinders needs to be visually observed using devices such as endoscopes, so that the corresponding maintenance plan can be selected based on the carbon deposit condition.

[0003] Current engine cylinder endoscopes use a flexible wire to insert a camera into the cylinder through spark plug holes, fuel injection holes, or other parts. After the camera is inserted into the cylinder, due to the limited diameter of the hole, it is difficult to control the camera to bend to the side, making it difficult to observe the carbon buildup on the inner walls of the engine cylinder, resulting in a rather one-sided observation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable engine cylinder carbon deposit visualization device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable engine cylinder carbon deposit visualization device includes a main unit with a display screen fixedly embedded thereon. One end of a telescopic rod is connected to the side wall of the main unit, and the other end of the telescopic rod is connected to a bending head. A camera is mounted on the bending head. Wires are installed inside the telescopic rod and the bending head, and the wires electrically connect the main unit and the camera.

[0007] Preferably, the telescopic rod includes a guide cylinder, a fixed column is fixedly installed at one end of the guide cylinder, the fixed column is rotatably connected to the main unit, a slide rod is slidably engaged at the other end of the guide cylinder, a guide block is fixedly installed on the slide rod, a guide groove is opened on the inner wall of the guide cylinder, and the guide block is slidably engaged with the guide groove.

[0008] Preferably, the bending head includes an intermediate block and a mounting head. The mounting head is located at the end of the slide rod away from the guide cylinder, and multiple intermediate blocks are provided between the mounting head and the slide rod. A rotating block is fixedly installed at the end of the slide rod and the intermediate blocks away from the guide cylinder. A rotating groove is opened at the end of the mounting head and the intermediate blocks near the guide cylinder. A short shaft is fixedly installed on the rotating block. The short shaft rotates and engages with the rotating groove. One end of the pull rope is fixedly connected to the side wall of the mounting head. A fixing plate is fixedly installed on the outer wall of the guide cylinder. The pull rope slides through the fixing plate and is fixedly connected to the pull ball.

[0009] Preferably, the inner walls on both sides of the rotating groove have round holes for engaging short shafts, and a torsion spring is installed between the short shaft and the round hole. The middle block and the end of the mounting head at the rotating groove have arc-shaped surfaces and stop surfaces on both sides, respectively. The stop surfaces movably fit against the sliding rods on both sides of the rotating block and the end of the middle block. A limit rod is fixedly installed on the side of the arc-shaped surface away from the stop surface.

[0010] Preferably, the axis of the arc-shaped surface coincides with the axis of the short axis, the intersection of the arc-shaped surface and the stop surface is located in the middle of the end face of the intermediate block and the mounting head, a camera is fixedly installed at the end of the mounting head away from the intermediate block, and multiple lighting beads are installed around the camera.

[0011] Preferably, a conductive slip ring is provided between the fixed column and the main unit, one end of the wire passes through the fixed column and is electrically connected to the conductive slip ring, the wire inside the guide cylinder has an elastic spiral structure, and the wire passes through the slide rod, the intermediate block, the rotating block and the mounting head and is electrically connected to the camera and the lighting lamp.

[0012] The portable engine cylinder carbon deposit visualization device proposed in this utility model has the following advantages:

[0013] 1. When the pull rope is not pulled, the torsion spring causes the middle block and the mounting head to rotate toward the stop surface, so that the ends of the slide rod and the middle block are in contact with the stop surface, achieving the purpose of automatic straightening. This makes it easy for the device to be inserted into or slide out of the engine cylinder. After being inserted into the engine cylinder, pulling the ball will pull the pull rope to move the mounting head. At this time, the mounting head and the middle block slide along the arc surface, thereby achieving the purpose of bending. The limit rod serves to limit the angle, so that the camera bends toward the inner wall of the engine cylinder, making it easy to fully observe the carbon deposits in the cylinder. It is convenient to use.

[0014] 2. The slide bar slides along the guide cylinder, which facilitates telescopic control. The guide block and guide groove serve as guides and limits the movement. The device can be reduced in size when not in use, making it easy to carry. The fixed column rotates between the main unit and the main unit, which allows the guide cylinder to be rotated after the bending head is bent, so that the camera can observe the inner wall of the cylinder.

[0022] Reference Figure 1 This application provides a portable engine cylinder carbon deposit visualization device, including a main unit 1, a display screen 2 fixedly embedded in the main unit 1, one end of a telescopic rod 3 connected to the side wall of the main unit 1, the other end of the telescopic rod 3 connected to a bending head 4, a camera mounted on the bending head 4, and wires 5 installed inside the telescopic rod 3 and the bending head 4, and the wires 5 electrically connect the main unit 1 and the camera. When not in use, the telescopic rod 3 is retracted to reduce the size of the device and make it easy to carry. When in use, the telescopic rod 3 is extended to control the bending head 4 to be in a straight state, so as to facilitate the insertion of the camera into the engine cylinder. Then, the bending head 4 is controlled to bend to the side, so as to facilitate full observation of the carbon deposits on the side wall of the engine cylinder. It is convenient to use.

[0023] Reference Figure 1 and Figure 2The telescopic rod 3 includes a guide cylinder 31. A fixed column 32 is fixedly installed at one end of the guide cylinder 31. The fixed column 32 is rotatably connected to the host 1. A sliding rod 33 is slidably engaged at the other end of the guide cylinder 31. A guide block 35 is fixedly installed on the sliding rod 33. A guide groove 34 is opened on the inner wall of the guide cylinder 31. The guide block 35 is slidably engaged with the guide groove 34. The sliding rod 33 slides along the guide cylinder 31, which facilitates telescopic control. The guide block 35 and the guide groove 34 serve as guides and limits. The fixed column 32 rotates with the host 1, which facilitates the rotation of the guide cylinder 31 after the bending head 4 is bent, so that the camera can observe the inner wall of the cylinder.

[0024] Furthermore, a rubber damping ring is fixedly installed on the inner wall of the end of the guide cylinder 31, and the damping ring is tightly attached to the outer wall of the slide rod 33 to achieve the purpose of sealing and improving damping, so that it can be fixed by friction after extension and contraction.

[0025] Reference Figure 1 , Figure 3 and Figure 4The bending head 4 includes an intermediate block 41 and a mounting head 42. The mounting head 42 is located at the end of the slide rod 33 away from the guide cylinder 31, and multiple intermediate blocks 41 are provided between the mounting head 42 and the slide rod 33. Rotating blocks 44 are fixedly installed at the ends of the slide rod 33 and the intermediate blocks 41 away from the guide cylinder 31. Rotating grooves 43 are opened at the ends of the mounting head 42 and the intermediate blocks 41 near the guide cylinder 31. Short shafts 45 are fixedly installed on the rotating blocks 44, and the short shafts 45 rotatably engage with the rotating grooves 43. The sidewall of the mounting head 42 One end of the pull rope 46 is fixedly connected. A fixing plate 47 is fixedly installed on the outer wall of the guide cylinder 31. The pull rope 46 slides through the fixing plate 47 and is fixedly connected to the pull ball. The inner walls of both sides of the rotating groove 43 have round holes for engaging the short shaft 45, and a torsion spring is installed between the short shaft 45 and the round hole. The middle block 41 and the end of the mounting head 42 at the rotating groove 43 have arc-shaped surfaces 431 and stop surfaces 432 on both sides respectively. The stop surfaces 432 movably fit against the sliding rods 33 on both sides of the rotating block 44 and the end of the middle block 41. A limit rod 433 is fixedly installed on the side of the arc-shaped surface 431 away from the stop surface 432. The axis of the arc-shaped surface 431 coincides with the axis of the short axis 45. The intersection of the arc-shaped surface 431 and the stop surface 432 is located in the middle of the end faces of the intermediate block 41 and the mounting head 42. A camera is fixedly installed on the end of the mounting head 42 away from the intermediate block 41, and multiple lighting beads are installed around the camera. When the pull rope 46 is not pulled, the torsion spring causes the intermediate block 41 and the mounting head 42 to rotate towards the stop surface 432, thus... The ends of the slide bar 33 and the intermediate block 41 are attached to the stop surface 432 to achieve automatic straightening, making it easy for the device to extend into or slide out of the engine cylinder. After extending into the engine cylinder, pulling the pull ball will pull the pull rope 46 to pull the mounting head 42. At this time, the mounting head 42 and the intermediate block 41 slide along the arc surface 431 to achieve bending. The limiting rod 433 serves to limit the angle, so that the camera bends towards the inner wall of the engine cylinder, making it easy to fully observe the carbon deposits in the cylinder and convenient to use.

[0026] Reference Figure 2 A conductive slip ring is provided between the fixed column 32 and the main unit 1. One end of the wire 5 passes through the fixed column 32 and is electrically connected to the conductive slip ring. The wire 5 inside the guide cylinder 31 has an elastic spiral structure. The wire 5 passes through the slide rod 33, the intermediate block 41, the rotating block 44 and the mounting head 42 and is electrically connected to the camera and the lighting lamp. The conductive slip ring can rotate the guide cylinder 31 while keeping the display screen 2 facing the staff, so that the camera can observe the inside of the cylinder. The elastic spiral structure of the wire 5 makes it easy for the slide rod 33 to automatically extend and retract synchronously.

[0027] Working principle: When the pull rope 46 is not pulled, the torsion spring causes the intermediate block 41 and the mounting head 42 to rotate toward the stop surface 432, so that the ends of the slide rod 33 and the intermediate block 41 are in contact with the stop surface 432, achieving automatic straightening. This facilitates the device's insertion into or sliding out of the engine cylinder. After being inserted into the engine cylinder, pulling the pull ball causes the pull rope 46 to pull the mounting head 42. At this time, the mounting head 42 and the intermediate block 41 slide along the arc surface 431, thereby achieving bending. The limiting rod 433 serves as an angle limiter, allowing the camera to bend toward the inner walls of the engine cylinder, facilitating full observation of carbon deposits inside the cylinder. It is convenient to use. The slide rod 33 slides along the guide cylinder 31, facilitating telescopic control. The guide block 35 and the guide groove 34 serve as guides and limits, reducing the size of the device when it is not in use, making it easy to carry. The fixed column 32 rotates between the main unit 1, allowing the guide cylinder 31 to rotate after the bending head 4 bends, enabling the camera to observe the inner walls of the cylinder.
