DETAILED DESCRIPTION OF THE EMBODIMENTS

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

[0025] Please refer to Figures 1-3 , the present invention provides a new technical solution: a swivel arm that is convenient for installation and fixation, including a fixed base 1, a swivel arm body 15 is fixedly connected to the fixed base 1, a bolt plate 16 is provided on the swivel arm body 15, a fixing component is provided on the fixed base 1, and the fixing component is used to fix the swivel arm body 15. The fixing component includes a chain fixing block 4, a chain 5, a first anti-slip strip 6, a sprocket 8, a worm wheel 10, a worm 12 and a motor 13;

[0026] Both of the chain fixing blocks 4 in the fixing component are fixedly connected to one side of the fixed base 1, and the two chains 5 are respectively fixedly connected to the chain fixing blocks 4, and two sliding grooves 2 are opened on the fixed base 1;

[0027] A plurality of rollers 3 are rotatably connected in each of the two sliding grooves 2, and the plurality of rollers 3 are used to reduce the friction force. The two chains 5 are respectively located in the corresponding sliding grooves 2.

[0028] Furthermore, a plurality of first anti-slip strips 6 are respectively fixedly connected to the side of the corresponding chain 5 close to the roller 3. The plurality of first anti-slip strips 6 are used to increase the fixing friction force, and the plurality of first anti-slip strips 6 are evenly distributed at equal intervals.

[0029] Furthermore, a plurality of fixing plates 7 are provided on the fixed base 1. Two sprockets 8 are respectively rotatably connected between the corresponding two fixing plates 7. The two sprockets 8 are respectively adapted to the corresponding chains 5, and the sprockets 8 are used to drive the tightening of the chains 5.

[0030] Furthermore, a worm gear shaft 9 is fixedly sleeved inside the worm gear 10. Both ends of the worm gear shaft 9 are fixedly inserted into the corresponding sprockets 8. The rotation of the worm gear shaft 9 can drive the two chains 5 to tighten simultaneously.

[0031] Furthermore, a worm gear fixing frame 11 is fixedly connected to the fixed base 1. A worm 12 is rotatably connected to the top plate of the worm gear fixing frame 11. A motor fixing groove is formed on the fixed base 1. A motor 13 is fixedly installed in the motor fixing groove. The output shaft of the motor 13 is fixedly inserted into the worm 12, and the worm 12 is meshed with the worm gear 10.

[0032] Furthermore, the bottom surface of the fixed base 1 is an arc surface. A plurality of second anti-slip strips 14 are fixedly connected to the bottom surface of the fixed base 1. Bolt plates 16 for fixing the loading arm with bolts when necessary are fixedly connected to both sides of the fixed base 1.

[0033] Furthermore, during use, the fixed base 1 is placed at a suitable fixing position, then the chain 5 is wound around the fixed trestle, and then the roller 3 is reinserted so that the sprocket 8 can be meshed with the chain 5. At this time, by starting the motor 13, the output shaft of the motor 13 drives the worm 12 thereon to rotate. When the worm 12 rotates, it can drive the two sprockets 8 to rotate through the worm gear shaft 9. When the two sprockets 8 rotate, they can drive the chain 5 to move to one side, thereby realizing the tightening of the chain 5. The fixing of the fixed base 1 and the loading arm body 15 is achieved by the tightening of the two chains 5. This avoids the situation of damaging the fixed object by opening holes in the fixed trestle and the oil tank when using bolts for fixing in the traditional method. And this tightening type of fixing can fix and install trestles and oil tanks of different sizes within the length range of the chain 5, which improves the applicability of the loading arm body 15.

[0034] Furthermore, due to the self-locking property of the worm gear 10 and the worm 12, the fixed base 1 and the articulated pipe body 15 thereon can be well fixedly connected to the loading and unloading trestle. Even when the motor 13 stops rotating, the chain 5 will not loosen, which greatly improves the stability of the articulated pipe fixation and prevents the accident of tipping during the use of the articulated pipe for loading and unloading materials due to excessive extension of the articulated pipe and large change in the center of gravity.

[0035] Furthermore, by providing a plurality of first anti-slip strips 6 on the chain 5, when the chain 5 is tightened, it can have a certain degree of friction with the fixed trestle, thereby further improving the stability of the chain 5 when tightened and fixed on the trestle. And by providing the second anti-slip strip 14, when the fixed base 1 is installed on the arched trestle or oil tank, the second anti-slip strip 14 can impose certain restrictions on the lateral movement of the fixed base 1, making the articulated pipe on the fixed base 1 more reliably fixed.

[0036] Working principle: During use, place the fixed base 1 at a suitable fixed position, then wind the chain 5 around the fixed trestle, and then reinsert the roller shaft 3 so that the sprocket 8 can mesh with the chain 5. At this time, start the motor 13, and the output shaft of the motor 13 drives the worm 12 thereon to rotate. When the worm 12 rotates, it can drive the two sprockets 8 to rotate through the worm gear shaft 9. When the two sprockets 8 rotate, they can drive the chain 5 to move to one side, thereby realizing the tightening of the chain 5.

[0037] Furthermore, due to the self-locking property of the worm gear 10 and the worm 12, the fixed base 1 and the articulated pipe body 15 thereon can be well fixedly connected to the loading and unloading trestle, so that even when the motor 13 stops rotating, the chain 5 will not loosen.

[0038] Furthermore, by providing a plurality of first anti-slip strips 6 on the chain 5, when the chain 5 is tightened, it can have a certain degree of friction with the fixed trestle, thereby further improving the stability of the chain 5 when tightened and fixed on the trestle. And by providing the second anti-slip strip 14, when the fixed base 1 is installed on the arched trestle or oil tank, the second anti-slip strip 14 can impose certain restrictions on the lateral movement of the fixed base 1.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
