Description

Technical Field

[0001] The utility model belongs to the field of vehicle tarpaulins, in particular to a new type of tarpaulin. Background Art

[0002] A vehicle tarpaulin is a covering material specially designed for vehicles, mainly used to protect the cargo loaded on the vehicle, the interior of the vehicle or the top of the vehicle from weather conditions such as rain, snow, sun exposure, dust and other environmental factors. This tarpaulin is usually made of high-quality fabric materials and has the characteristics of being waterproof, UV-resistant, wear-resistant, and weather-resistant, and can adapt to harsh outdoor environments. An existing vehicle tarpaulin includes a tarpaulin 1 such as Figure 1 As shown, a plurality of evenly distributed slip rings 2 are installed on the tarpaulin 1, and the slip rings 2 are sleeved on the steel wire rope 3. One end of the steel wire rope 3 is fixedly connected to the bobbin 4, and the bobbin 4 is rotatably installed on the upper side of the cab 100. The bobbin 4 is driven by a motor 30. The other end of the steel wire rope 3 is fixedly connected to a bending rod 9, and the bending rod 9 is rotatably installed on the bottom plate of the truck bucket 101. The bending rod 9 and the bottom plate are connected by a tension spring 10. When the tarpaulin 1 does not need to cover the truck bucket 101, the motor 30 drives the bobbin 4 to rotate forward, thereby driving the steel wire rope 3 to be wound around the bobbin 4, and the distance between the plurality of slip rings 2 is shortened, and the tarpaulin 1 is folded. The bending rod 9 stretches the tension spring 10, so that the tension spring 10 is in a stretched state. When the tarpaulin 1 is needed to cover the truck bed 101, the motor 30 drives the spool 4 to rotate in the opposite direction to loosen the wire rope 3 wound on the spool 4. Under the tension of the tension spring 10, the bending rod 9 rotates to drive the tarpaulin 1 to partially unfold. When the tension spring 10 is reset, the tarpaulin 1 is fully unfolded under the action of the gravity of the bending rod 9. However, the above structure has a great disadvantage, that is, due to the presence of the bending rod 9 on the front and rear sides of the truck bed 101, the bucket doors on the front and rear sides of the truck bed 101 cannot be opened, resulting in low efficiency in loading and unloading goods. For this reason, we have designed a new tarpaulin. Utility Model Content

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] A new type of tarpaulin, such as Figure 1 , 2, 3, 4, 5, and 6, comprising a tarpaulin 1, on which are mounted several evenly distributed slip rings 2, the slip rings 2 being arranged in several rows, each row being provided with several slip rings 2, the upper side of the tarpaulin 1 being fixedly connected to the slip rings 2, the corresponding slip rings 2 being sleeved on the steel wire ropes 3, one end of the several steel wire ropes 3 passing through the transverse plate 7 to be fixedly connected to the bobbin 4, the transverse plate 7 being provided with several through holes, the steel wire ropes 3 being slidably mounted in the corresponding through holes, the bobbin 4 being rotatably mounted on the cab 100, the two ends of the bobbin 4 being rotatably mounted on the upper side of the cab 100 through the axle seats, and the cab 100 The upper side is provided with a driving device for driving the wire shaft 4 to rotate, the other end of the wire rope 3 is fixedly connected to the rotating rod 5 through the connecting plate 6, one side of the tarpaulin 1 is fixedly connected to the connecting plate 6, and the other side of the tarpaulin 1 is fixedly connected to the cross plate 7. A bucket 101 is provided on one side of the cab 100, and the bucket 101 includes a bottom plate and side baffles on the front and rear sides and a rear baffle away from the cab 100. It is characterized in that: the front and rear sides of the cab 100 are respectively rotatably installed with a sliding sleeve 8, the rotating rod 5 is slidably installed in the sliding sleeve 8, and the inner wall of the sliding sleeve 8 is in sliding contact with the outer wall of the rotating rod 5. The utility model has a simple structure and an ingenious design. By changing the position of the end of the rotating rod 5, the rotating rod 5 does not block the side baffles on the front and rear sides of the bucket 101, so that the side baffles on the front and rear sides can be opened smoothly, which can meet actual needs and is suitable for promotion. When the utility model is used and the cargo in the truck bed 101 does not need to be shielded, the driving device is used to drive the spool 4 to rotate in the forward direction, driving several steel wires 3 to be wound around the spool 4, and the steel wires 3 drive the end of the tarpaulin 1 to move through the slip ring 2, and at the same time drive the connecting plate 6, the rotating rod 5 and the sliding sleeve 8 to rotate. As the angle of the rotating rod 5 changes, the rotating rod 5 slides along the inner circumference of the sliding sleeve 8. Since the length of the rotating rod 5 extending out of the end of the sliding sleeve 8 becomes shorter, the tarpaulin 1 can be stored and folded as the steel wires 3 are tightened, and the truck bed 101 can be opened at this time. The side baffles on the front and rear sides are used to load and unload goods; when the goods in the truck bed 101 need to be shielded, the side baffles on the front and rear sides of the truck bed 101 are first folded up, and then the driving device is used to drive the spool 4 to rotate in the opposite direction, and several steel wire ropes 3 are loosened. At this time, as several steel wire ropes 3 are loosened and the rotating rod 5 is manually rotated to a horizontal state, until the tarpaulin 1 completely covers the truck bed 101, when the steel wire ropes 3 are wound around the spool 4, due to the presence of the cross plate 7, several slip rings 2 are blocked, so that the slip rings 2 will not be wound around the spool 4 together with the steel wire ropes 3.

[0017] Specifically, as shown in the figure, the outer circumference of the bobbin 4 in this embodiment is fixedly mounted with a plurality of annular partitions 20. The annular partitions 20 separate the plurality of steel wire ropes 3 to prevent the steel wire ropes 3 from sliding and winding in the axial direction.

[0018] Further, as shown in the figure, the driving device described in this embodiment includes a motor 30, the output shaft of the motor 30 is fixedly installed with a coaxial worm 21, the worm 21 is rotatably installed on the upper side of the cab 100 through the shaft seat, one side of the worm 21 is meshed with a worm wheel 22, the worm wheel 22 is coaxially fixedly connected with the spool 4, and the worm wheel 22 and the worm 21 are self-locking. The output shaft of the motor 30 rotates to drive the worm 21 to rotate, and then drives the worm wheel 22 meshed with the worm 21 to rotate, thereby driving the spool 4 to rotate.

[0019] Furthermore, as shown in the figure, the rotating rod 5 described in this embodiment includes an outer tube 40, which is slidably installed in the sliding sleeve 8, and the inner rod 41 is slidably installed in the outer tube 40, and the end of the inner rod 41 is fixedly connected to the connecting plate 6. The inner rod 41 and the outer tube 40 are connected by a first spring 42, and the first spring 42 is sleeved on the outer periphery of the inner rod 41, one end of the first spring 42 is fixedly connected to one end of the outer tube 40, and the other end of the first spring 42 is fixedly connected to the outer periphery of the inner rod 41, and the outer tube 40 and the sliding sleeve 8 are connected by a second spring 43, the second spring 43 is sleeved on the outer periphery of the outer tube 40, one end of the second spring 43 is fixedly connected to the outer periphery of the outer tube 40, and the other end of the second spring 43 is fixedly connected to the sliding sleeve 8. When the rotating rod 5 rotates to a vertical state, the inner rod 41 enters the outer tube 40, the first spring 42 and the second spring 43 are compressed, and the length of the rotating rod 5 is shortened, so that the rotating rod 5 occupies less space in the vertical state. When the rotating rod 5 returns to a horizontal state, under the action of the elastic force of the first spring 42 and the second spring 43, the inner rod 41 moves to the outside of the outer tube 40, and the rotating rod 5 returns to its original length, which does not affect its use.

[0020] Furthermore, as shown in the figure, the two ends of the outer tube 40 in this embodiment are provided with retaining rings 50, and the outer diameter of the retaining ring 50 is larger than the inner diameter of the sliding sleeve 8. The retaining ring 50 can prevent the outer tube 40 from sliding out of the sliding sleeve 8.

[0021] Furthermore, as shown in the figure, a stopper 60 is provided on one side of the sliding sleeve 8 of the present embodiment, and the stopper 60 is fixedly mounted on the cab 100, and the side wall of the sliding sleeve 8 can abut against and contact with the side wall corresponding to the stopper 60. When the sliding sleeve 8 is placed horizontally, the lower side of the sliding sleeve 8 abuts against and contacts with the upper side of the stopper 60, so that the sliding sleeve 8 is more stable when placed horizontally, and the sliding sleeve 8 is prevented from tilting to the lower left; when the sliding sleeve 8 is placed vertically, the left side of the sliding sleeve 8 abuts against and contacts with the right side of the stopper 60, so that the sliding sleeve 8 is more stable when placed vertically.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
