Description

Technical Field

[0001] The invention relates to the technical field of inflatable pulp boards, and in particular to an inflatable pulp board with adjustable length. Background Art

[0002] Inflatable paddle board, also known as inflatable paddle board or inflatable stand-up paddle board (SUP), is a light, easy to carry and store water sports equipment. Inflatable paddle boards can be divided into many types according to their uses and sizes, such as racing, leisure, fishing, etc. Different types of inflatable paddle boards differ in board width, length, thickness and additional accessories to meet the needs of different users.

[0003] Features and Benefits Portability: The inflatable paddle board can be deflated and folded into a smaller volume when not in use, making it easy to carry and store, making it ideal for travel or home use.

[0004] Durability: Inflatable paddle boards are usually made of high-strength materials such as PVC or nylon, which have good wear and weather resistance and long service life.

[0005] Stability: Compared with traditional hard paddle boards, inflatable paddle boards usually have wider boards and thicker edges, which can provide better stability and buoyancy, and are suitable for beginners and children.

[0006] Existing inflatable paddle boards are usually designed with a fixed length. Once inflated, the length cannot be adjusted. This limits its applicability in different scenarios and conditions. Since the length cannot be adjusted, inflatable paddle boards may not be suitable for different waters, different users or different usage needs.

[0024] like Figure 3 As shown, two clamping holes A101 are provided on one side of the paddle board head 1 close to the paddle board body 3 .

[0025] Two snap-in holes B201 are provided on one side of the paddle board tail 2 close to the paddle board body 3 .

[0026] like Figure 4 As shown, two plug-in blocks 301 are connected and fixedly arranged on both sides of the spliced ​​pulp board body 3, and a snap-in block 302 is slidably arranged in the plug-in block 301. A spring A303 is connected and fixedly arranged at the bottom end of the snap-in block 302, and the other end of the spring A303 is connected and fixedly arranged with the inner wall of the plug-in block 301. The top of the plug-in block 301 is provided with an inclined surface, and two snap-in holes C304 are provided on both sides of the spliced ​​pulp board body 3.

[0028] like Figure 6As shown, the outer wall of the top of the sealing plug 5 is movably plugged with the inner wall of the air guide hole 404, the bottom of the sealing plug 5 is sleeved with a spring B501, the bottom of the sealing plug 5 is connected and fixed with a contact rod 502, the contact rod 502 is slidably matched with the inner wall of the air guide seat 4, the inner wall of the contact rod 502 is rotatably connected with a limit rod 503, and the bottom end of the limit rod 503 is movably contacted with the bottom end of the air guide seat 4. The spring B501 realizes the automatic reset of the sealing plug 5. The contact rod 502 drives the connected sealing plug 5 to move downward, so that the air guide hole 404 is connected. At this time, air is inflated into the inflatable cushion 8 through the air pump. When the inflation end of the air pump is removed after the inflation is completed, the spring B501 will drive the sealing plug 5 to reset and seal the air guide hole 404. At the same time, when exhaust is needed, after manually pressing the contact rod 502, the limit rod 503 is rotated to make its bottom end contact with the bottom end of the air guide seat 4 for limiting, so that the sealing plug 5 remains in an open state for rapid exhaust.

[0029] like Figure 7 As shown, the adjustment mechanism 6 includes a universal joint 601, which is rotatably connected to the inner wall of the paddle board head 1, a knob 602 is fixedly connected to the outer end of the universal joint 601, a worm 603 is fixedly connected to the inner end of the universal joint 601, the worm 603 is rotatably connected to the inner wall of the paddle board head 1, a worm wheel 604 is meshingly provided on one side of the worm 603, the worm wheel 604 is rotatably connected to the inner wall of the paddle board head 1, and a push rod 605 is fixedly connected to the worm wheel 604. The knob 602 is turned to drive the worm 603 connected to the knob 602 through the universal joint 601 to rotate, so that the worm 603 drives the push rod 605 connected to the worm wheel 604 to rotate.

[0030] like Figure 8 As shown, the support and protection mechanism 7 includes two moving plates 701, the moving plates 701 are slidably matched with the inner wall of the paddle board head 1, the inner end of the moving plates 701 is connected and fixedly provided with a moving rod 702, the moving rod 702 is slidably contacted with the outer wall of the push rod 605, a plurality of tension springs B703 are connected and fixedly provided between the moving plates 701 and the inner wall of the paddle board head 1, a rotating rod 704 is rotatably connected and provided through the inner wall of one end of the moving plates 701, a supporting rod 705 is connected and fixedly provided at the outer end of the rotating rod 704, a transmission groove 706 is provided on the outer wall of the inner end of the rotating rod 704, a fixed guide head 707 is slidably matched with the inner wall of the transmission groove 706, and the fixed guide head 707 is connected and fixedly provided with the inner wall of the paddle board head 1. The tension spring B703 realizes the automatic reset of the moving plate 701. When the push rod 605 rotates, the moving plate 701 connected to the moving rod 702 is pushed out. At this time, under the action of the fixed guide head 707, the rotating rod 704 with a transmission groove 706 is rotated, thereby driving the support rod 705 to stand up.

[0031] like Fig. 9As shown, a limit block 901 is slidably provided on the inner wall of the opening on one side of the placement seat 9, an inclined surface is provided on the outer end of the limit block 901, a spring C902 is connected and fixedly provided on the inner end of the limit block 901, and the spring C902 is connected and fixedly provided on the inner wall of the placement seat 9. The spring C902 ensures the stable limit of the limit block 901.

[0032] Working principle: When the inflatable paddle board is needed, the plug block 301 at one end of the spliced ​​paddle board body 3 is inserted into the clamping hole A101 of the paddle board head 1. At this time, the spring A303 will drive the clamping block 302 to clamp in the clamping hole A101, so as to realize the splicing between it and the paddle board head 1, and at the same time, the other spliced ​​paddle board bodies 3 are spliced ​​with the paddle board tail 2; After the splicing is completed, the inflatable cushion 8 is inflated. First, the cover plate 403 connected to the sliding rod 401 is pulled up and rotated, and then the inflatable end of the air pump is threadedly connected to the air guide seat 4. At this time, the inflatable end of the air pump will contact and squeeze the contact rod 502, so that the contact rod 502 drives the connected sealing plug 5 to move downward, so that the air guide hole 404 is connected. At this time, the air pump is used to inflate the inflatable cushion 8. When the inflatable end of the air pump is removed after the inflation is completed, the spring B501 drives the sealing plug 5 to reset and seal the air guide hole 404. At the same time, when exhaust is required, after manually pressing the contact rod 502, the limit rod 503 is rotated to make its bottom end movably contact with the bottom end of the air guide seat 4 for limiting, so that the sealing plug 5 remains in an open state for rapid exhaust. When the inflatable paddle board is in use, the limit block 901 is pulled open, and the paddle 10 is taken out of the placement seat 9 for use. When the inflatable paddle board is not in use temporarily, the knob 602 is turned, so that the knob 602 drives the connected worm 603 to rotate through the universal joint 601, so that the worm 603 drives the push rod 605 connected to the worm gear 604 to rotate; When the push rod 605 rotates, the moving plate 701 connected to the moving rod 702 is pushed out. At this time, under the action of the fixed guide head 707, the rotating rod 704 with a transmission groove 706 is rotated, thereby driving the support rod 705 to stand upright, supporting the inflatable paddle board and preventing its bottom from contacting the ground.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
