Description

Technical Field

[0001] The invention relates to the technical field of vehicle parts, and in particular to a cable winding drum structure which can be turned upside down. Background Art

[0002] For general-purpose vehicles or special-purpose vehicles equipped with cable reels, when it is necessary to power the equipment on the vehicle, the cable reel needs to be manually rotated to unfold the cable to connect to the external power supply. In the prior art, since the wheels occupy a large height, the cable reel is located at a high position in the vehicle compartment, which makes it difficult for workers to retract and release the cable, which is time-consuming and laborious. Moreover, when the cable is unfolded, the cable reel rotates rapidly, and the impact force is large, which may cause impact damage to the vehicle body and the cable reel itself. At the same time, the large impact force also poses a safety hazard to the operator. Summary of the invention

[0003] The purpose of the present invention is to provide a cable reel structure that can be turned upside down to solve the problem that the cable reel in the prior art is located at a high position in the vehicle, which makes it inconvenient, time-consuming and labor-intensive for workers to operate when reeling in and out the cables.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A cable reel structure that can be flipped up and down, comprises a fixed base, a sliding base, a flip base and a cable reel, the fixed base is fixedly arranged on a vehicle body, a slide rail along the horizontal direction is provided between the sliding base and the fixed base, the sliding base can slide along the slide rail until it partially extends out of the fixed base, the extended end of the sliding base is hinged to the flip base, the hinge axis is along the horizontal direction and perpendicular to the slide rail, the cable reel is rotatably connected to the flip base, and the flip base can drive the cable reel to flip along the hinge axis between above and below the sliding base.

[0006] The present invention adopts the above-mentioned technical solution, by adding a fixed base, a sliding base and a flip base to the cable reel. When the cable needs to be retracted or released, the sliding base is first slid out from the fixed base (to prevent the subsequent flip base from flipping downward and interfering with the vehicle body), and then the flip base is used to drive the cable reel to flip from the top of the sliding base to the bottom, thereby reducing the height of the cable reel. Compared with the prior art in which the cable reel in the vehicle is located at a higher position, which makes it inconvenient, time-consuming and labor-intensive for workers to operate when retracting and releasing the cables, the present invention can flip the cable reel to a lower position, making it convenient for workers to operate when retracting and releasing the cables, saving time and effort.

[0007] Furthermore, the cross-sections of the fixed base and the sliding base are both U-shaped with the opening upward, the sliding base is embedded in the fixed base, the sliding rail is provided between the side walls on the same side of the fixed base and the sliding base, the sliding rail is provided between the bottom plates of the fixed base and the sliding base, and multiple sliding rails are provided between the fixed base and the sliding base, so that the sliding connection between the fixed base and the sliding base is more stable and reliable.

[0008] Furthermore, a sliding locking pin is provided at the front end of the side wall of the fixed base, and a first pin hole and a second pin hole cooperating with the sliding locking pin are respectively provided at the front end and the rear end of the side wall of the sliding base; a flip locking pin is provided above the bottom plate of the sliding base, and a third pin hole cooperating with the flip locking pin is provided on the flip base; a rotating locking pin is provided on the flip base, and a fourth pin hole cooperating with the rotating locking pin is provided on the cable reel. When the cable reel flipping structure is in a folded state, the sliding base, the flipping base and the cable reel are locked by respectively cooperating with the first pin hole, the third pin hole and the fourth pin hole through the sliding locking pin, the flip locking pin and the rotating locking pin; when the cable needs to be retracted or released, the sliding base slides outward, and the fixed base and the sliding base are locked by cooperating with the second pin hole through the sliding locking pin, and at the same time the flip locking pin and the rotating locking pin are in an unlocked state, which is convenient for flipping the flip base and rotating the cable reel.

[0009] Furthermore, a limit block is provided on the flip base. When the flip base is flipped to the bottom of the sliding base, the limit block is used to abut against the lower surface of the bottom plate of the sliding base to limit the flipping of the flip base. The limit block limits the position of the flip base to prevent its shaking from affecting the staff's retracting and releasing of cables.

[0010] Furthermore, a protruding elastic pad is provided on the limit block, and the limit block is abutted against the sliding base through the elastic pad. The elastic pad is used for buffering to prevent the flip base from colliding with the sliding base and causing damage after flipping downward.

[0011] Furthermore, the centers of both ends of the cable drum are respectively provided with a first rotating shaft and a second rotating shaft protruding outward, and the cable drum is rotatably connected to the flip base via the first rotating shaft and the second rotating shaft, the first rotating shaft is inserted into a wire-releasing damper preset on the flip base, and the second rotating shaft is inserted into a connecting bearing preset on the flip base, and the wire-releasing damper mitigates the large impact force generated by the rapid rotation of the cable drum when the cable is unfolded, thereby reducing the impact damage that may be caused to the vehicle body and the cable drum itself.

[0012] Furthermore, the end of the second rotating shaft is connected to the wire-reeling rocker arm through a steering gear, and the rotating axis of the wire-reeling rocker arm is perpendicular to the second rotating shaft. Rotating the wire-reeling rocker arm can drive the second rotating shaft to rotate, thereby driving the cable drum to rotate and reel in.

[0013] Furthermore, the wire-reeling rocker arm comprises a rocker arm connecting tube and a rocker arm handle which are pluggable. The rocker arm connecting tube is connected to the steering gear. When the cable reel flipping structure is in a folded state, the rocker arm handle is removed to reduce the space occupied by the structure. When the cable needs to be retracted or released, the rocker arm handle is plugged in, which is convenient and quick.

[0014] Furthermore, arc-shaped handles are provided on the flip base at both ends close to the cable drum, so that the cable drum can be flipped by holding the handles, which makes the operation more convenient and safer.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the cable reel can be flipped to a lower position, making it convenient for workers to operate when retracting and releasing the cable, saving time and effort; a newly added wire-releasing damper reduces the large impact force generated by the rapid rotation of the cable reel when the cable is unfolded, reducing the impact damage that may be caused to the vehicle body and the cable reel itself; a handle is provided on the flip base, which is convenient for flipping the cable reel by holding the handle, making the operation more convenient and safer.

[0028] A sliding lock pin 5 is provided at the front end of the side wall of the fixed base 1, and a first pin hole and a second pin hole are provided at the front end and the rear end of the side wall of the sliding base 2 respectively, which cooperate with the sliding lock pin 5; a flip lock pin 6 is provided above the bottom plate of the sliding base 2, and a third pin hole is provided on the flip base 3 to cooperate with the flip lock pin 6; a rotating lock pin 7 is provided on the flip base 3, and a fourth pin hole is provided on the cable drum 4 to cooperate with the rotating lock pin 7; Figure 5 As shown, a first lock pin bracket 17 is provided on the bottom plate of the sliding base 2, and the flip lock pin 6 is installed on the first lock pin bracket 17; Figure 7 As shown, a second lock pin bracket 18 is provided on the flip base 3, and the rotating lock pin 7 is installed on the second lock pin bracket 18;

[0029] A limit block 13 is provided on the flip base 3. When the flip base 3 is flipped to below the sliding base 2, the limit block 13 is used to abut against the lower surface of the bottom plate of the sliding base 2 to limit the flipping of the flip base 3.

[0030] The limit block 13 is provided with a protruding elastic pad 16, and the limit block abuts against the sliding base 2 through the elastic pad 16;

[0031] The cable drum 4 is provided with a first rotating shaft and a second rotating shaft protruding outward at the centers of both ends thereof, respectively. The cable drum 4 is rotatably connected to the flip base 3 via the first rotating shaft and the second rotating shaft. The first rotating shaft is inserted into a wire-releasing damper 8 preset on the flip base 3, and the second rotating shaft is inserted into a connection bearing 20 preset on the flip base 3.

[0032] The end of the second rotating shaft is connected to the wire-receiving rocker arm through a steering gear 19, and the rotating axis of the wire-receiving rocker arm is perpendicular to the second rotating shaft;
