Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Such as Figures 1-6As shown in the figure, an adjustable-angle forklift protection handrail includes a forklift main body 1; an operating rod 11 is installed on the top of the forklift main body 1; a bracket 12 is fixedly connected to the middle of the forklift main body 1; two groups of connecting rods 13 are installed in the middle of the bracket 12; a connecting block 14 is fixedly connected to the end of the connecting rod 13; a rotating plate 15 is rotatably connected to the middle of the connecting block 14; a handrail main body 16 is fixedly connected to the top of the rotating plate 15; a plurality of card slots 17 are formed in the middle of the rotating plate 15; a plurality of first springs 18 are fixedly connected to the inner wall of the connecting block 14; the bottoms of the plurality of first springs 18 are fixedly connected to a pin 19; the pin 19 is slidably arranged on the inner wall of the connecting block 14; the top of the pin 19 is arranged to match the shape of the card slot 17; during work, the staff needs to stand on the middle of the forklift main body 1 first, then turn on the switch of the forklift main body 1 and use the operating rod 11 to drive it, and transfer the goods to be transported. By arranging a handrail main body 16 in the middle of the forklift main body 1, the staff can place their arms on the top of the handrail main body 1. When the placement angle of the handrail main body 1 needs to be adjusted, the staff can respectively pull the bottoms of the two groups of pins 19, so that the pins 19 slide in the middle of the connecting block 14. At this time, the length of the first spring 18 will change until the top of the pin 19 is separated from the inner wall of the card slot 17. Then the staff can rotate the top of the handrail main body 1 and make a plurality of card slots 17 approach the top of the pin 19 in turn. After the angle of the handrail main body 1 is adjusted, the staff can release the bottom of the pin 19 and use the reaction force generated after the first spring 18 is stretched, so as to transfer the top of the pin 19 to the middle of the card slot 17 and fix the working position of the handrail main body 1. This step, combined with the rotatable handrail main body 1 in the middle of the connecting block 14, can improve the flexibility of the handrail main body 1 during work and reduce the problem that the position of the staff's arm is difficult to adjust for a long time due to the fixed installation of the handrail main body 1, resulting in hand soreness, and improve the comfort of the staff when driving the forklift main body 1.

[0026] As Figures 1-6As shown in the figure, a rotating pipe 2 is rotatably connected to the middle of the bracket 12; two groups of screw rods 21 are threadedly connected between the rotating pipe 2 and the middle of the bracket 12; the two groups of screw rods 21 are symmetrically arranged; two groups of slide rails 22 are fixedly connected to the middle of the forklift body 1; a slider 23 is slidably connected to the middle of the slide rail 22; the slider 23 is rotatably arranged at the end of the screw rod 21; the middle of the slider 23 is fixedly connected to the connecting rod 13; during operation, by providing a rotatable rotating pipe 2 in the middle of the bracket 12, when it is necessary to adjust the distance between the two armrest bodies 16, the staff can touch the middle of the rotating pipe 2 with their hands and rotate the rotating pipe 2 clockwise or counterclockwise. Since the two groups of screw rods 21 are symmetrically arranged between the rotating pipe 2 and the middle of the bracket 12, during the rotation of the rotating pipe 2, the two groups of screw rods 21 will gradually move away from or close to each other. Cooperating with the slide rail 22, the slider 23 can slide in the middle of the slide rail 22, so as to adjust the distance between the two armrest bodies 16. This step, combined with the two groups of screw rods 21 provided in the middle of the bracket 12, can adjust and change the distance between the two armrest bodies 16, further improving the flexibility of the armrest body 16 during operation, reducing the problem that the distance is too close or too short when the staff with significantly different body shapes place their arms on the middle of the armrest body 16 when driving in the middle of the forklift body 1, further improving the comfort of the staff when driving the forklift body 1, and reducing the problem of troublesome operation when operating the forklift body 1.

[0027] As Figures 1-6 shown, a clamping member 3 is fixedly connected to the end of one group of the armrest bodies 16; an elastic rope 31 is fixedly connected to the end of the other group of the armrest bodies 16; a clamping block 32 matching the shape of the clamping member 3 is fixedly connected to the end of the elastic rope 31; during operation, by providing a clamping block 32 in the middle of the armrest body 16, after the staff stands on the middle of the forklift body 1, they can turn and clamp the clamping block 32 on the middle of the clamping member 3, thereby enclosing the staff. This step, combined with the elastic rope 31 provided in the middle of the two groups of armrest bodies 16, can reduce the problem that the staff's body topples over in the middle of the forklift body 1 due to a large inertia when turning.

[0028] As Figures 1-6 shown, a plurality of second springs 4 are fixedly connected to the side wall of the armrest body 16; a top plate 41 is fixedly connected to the end of the second spring 4; during operation, by providing a top plate 41 on the side wall of the armrest body 16, when the staff's body approaches both sides of the armrest body 16 during driving, it will first hit the middle of the top plate 41 and squeeze a plurality of second springs 4 to make their lengths retract. This step uses the top plate 41 made of a soft material to reduce the force when the staff hits the middle of the top plate 41, and at the same time, using the retractable second springs 4 will further reduce the force when the staff hits the middle of the top plate 41.

[0029] As shown Figures 1-6 As shown, a scraper 5 is fixedly connected to the end of the bracket 12; the inner wall of the scraper 5 is in contact with the middle part of the screw rod 21; during operation, by arranging the scraper 5 in the middle of the bracket 12, when the screw rod 21 rotates in the middle of the bracket 12, the middle part of the screw rod 21 will directly contact the inner wall of the scraper 5 made of soft material. This step, combined with the contact surface between the inner groove of the screw rod 21 and the scraper 5, can improve the cleanliness of the middle part of the screw rod 21 and reduce the problem of large resistance during rotation due to a large amount of surface impurities when the screw rod 21 rotates in the middle of the bracket 12.

[0030] As shown Figures 1-6 As shown, a reinforcing rod 6 is fixedly connected to the middle of the top plate 41; during operation, by arranging the reinforcing rod 6 on the inner wall of the top plate 41, the reinforcing rod 6 will reinforce the top plate 41. This step, combined with the reinforcing rod 6, can reduce the problem of inward curling of the top plate 41 after long-term use and improve the stability of the top plate 41 during operation.

[0031] As shown Figures 1-6 As shown, the middle part of the rotating pipe 2 is recessed; during operation, by setting the middle part of the rotating pipe 2 to be recessed, this step, combined with the recessed groove body in the middle of the rotating pipe 2, can improve the friction force when the staff rotates the rotating pipe 2 and reduce the phenomenon of hand slipping.

[0032] As shown Figures 1-6 As shown, a rubber pad 7 is fixedly connected to the top of the armrest main body 16; the middle part of the rubber pad 7 is arc-shaped; during operation, by arranging the rubber pad 7 made of soft material on the top of the armrest main body 16, the staff's arm will directly contact the rubber pad 7. This step, combined with the soft material rubber pad 7, can increase the contact area between the staff's arm and the rubber pad 7 and improve the friction force when the staff's arm is placed on the top of the armrest main body 16.

[0033] Working principle: First, stand on the middle part of the forklift body 1, then turn on the switch of the forklift body 1 and use the operating lever 11 to drive it, and transfer the position of the goods to be transported. Since there is a handrail main body 16 provided in the middle of the forklift body 1, the arms of the staff can be placed on the top of the handrail main body 16. When it is necessary to adjust the placement angle of the handrail main body 16, the staff can respectively pull the bottoms of the two groups of pins 19, so that the pins 19 slide in the middle of the connecting block 14. At this time, the length of the first spring 18 will change until the top of the pin 19 is separated from the inner wall of the card slot 17. Then, the staff can rotate the top of the handrail main body 16 and make multiple card slots 17 approach the top of the pin 19 in turn. After the angle adjustment of the handrail main body 16 is completed, the staff can release the bottom of the pin 19, and use the reaction force generated after the first spring 18 is stretched, and then transfer the top of the pin 19 to the middle of the card slot 17 and fix the working position of the handrail main body 16. Since there is a rotatable rotating pipe 2 provided in the middle of the bracket 12, when it is necessary to adjust the distance between the two groups of handrail main bodies 16, the staff can contact the middle of the rotating pipe 2 with the hand and rotate the rotating pipe 2 clockwise or counterclockwise. Since the two groups of screw rods 21 are symmetrically arranged in the middle of the rotating pipe 2 and the bracket 12, when the rotating pipe 2 is rotated, the two groups of screw rods 21 will gradually move away from or close to each other. Cooperating with the slide rail 22, the slider 23 can slide in the middle of the slide rail 22, so as to adjust the distance between the two groups of handrail main bodies 16. Since there is a clamping block 32 provided in the middle of the handrail main body 16, after the staff stands on the middle part of the forklift body 1, they can turn and clamp the clamping block 32 on the clamping part 3, so as to enclose the staff. Since there is a top plate 41 provided on the side wall of the handrail main body 16, when the staff approaches the two sides of the handrail main body 16 when driving the forklift body 1, they will first hit the middle of the top plate 41 and squeeze the multiple second springs 4 so that their lengths contract. Since there is a scraper 5 provided in the middle of the bracket 12, when the screw rod 21 rotates in the middle of the bracket 12, the middle of the screw rod 21 will directly contact the inner wall of the scraper 5 made of soft material. Since there is a reinforcing rod 6 provided on the inner wall of the top plate 41, the reinforcing rod 6 will reinforce the top plate 41. The middle of the rotating pipe 2 is set to be concave.
