Description of the new model: [Technical field to which the new model belongs] This creation relates to the structure of a shock-absorbing caster, which is mainly aimed at the shock-absorbing caster with upper and lower two-stage complementary shock-absorbing cushioning settings to make it shock-proof. In addition to stabilizing compressive stress, casters can also effectively balance shocks during the undulations through the ground pits, so as to highlight the substantial benefits of the product structure of the suspension casters. [Prior art] Press, please refer to the first to third figures to learn the structure of one of the suspension feet and wheels, including: a fixed base (1 0), the fixed base (1 0) is installed at the bottom of a vehicle (such as a cart, not shown); a swivel base (20), which is a movable pivot under the fixed base (1 0), can be It is used for rotation; a wheel frame (30) is located below the turntable (2), and a wheel (301) is fixedly pivoted, and one end of the wheel frame (30) and the turntable (2) 0) the corresponding side is pivotally combined; _ an elastic element (40), the elastic element (40) (such as a spring) abuts horizontally between the turntable (20) and the wheel frame (30); When the fixed base (1 0) of the shock-absorbing caster is under heavy pressure from the carrier, the wheel frame (30) immediately compresses the elastic element (40), and the characteristics of the elastic element (40) are used to achieve shock absorption. effect. In addition, please refer to the fourth and fifth figures, the structure of the second suspension caster is known, and it is also pivoted with the fixed base (10), the swivel (20), and the wheel frame (30). The wheel (3 0 1) has the same technology, but its difference is 5 M267086, which is attached to the wheel frame (30) on both sides of the corresponding side are provided with a swing arm (50), a square arm (50)-end An extension section (501) is formed, and an elastic unit (60) (such as a hydraulic shock absorber) is pivotally arranged on the extension section (501), and the elastic unit (60)-the end and the wheel (30)丄) The sleeve center is in a frame setting position. According to this, when the fixed base (10) is under heavy pressure from the carrier, the elastic unit (6 is controlled between the rotary arm (5 ^ and the axis of the wheel (3 G 1)) 〇) to produce a shock-absorbing effect of the shock-absorbing ability. Elasticity I: The above—or the other two—the structure of the shock-absorbing casters, the setting of the ==: (40) or the elastic unit (60), both The t-force caster in the compressed state passes through the uneven ground and has a simple suction-hole function. However, when the shock-absorbing caster passes through the ground from the pit == 2 sections, the elastic element (4〇) or the bomb is released, and Order suspension The stored energy will be the damage of the vehicle. The large-scale vibration rebounds and jumps, and then the caster structure is built. 1 Whether it is one or two of the shock absorbers that roll across the ground = / 1, when it vibrates in the amplitude The situation ^ φ has caused a rapid rebound, but there is still a great improvement in the design, with a view to improving the advancement of the ground pit 2 surgery and then make progress == the essence of the persuasion product: beneficial shock absorption and release energy This creative system provides a 1 shock The structure of the caster mainly includes a fixed M267086 fixed seat, a turntable, a caster with a wheel frame, upper and lower elastic elements, and a connecting rod. The upper and lower elastic elements are respectively disposed above and below the wheel frame, and = The objects are sequentially passed through the upper and lower elastic elements and positioned at 0 'of the wheel frame to the turntable, so that the upper miscellaneous element is abutted on the wheel frame ^ to the turntable, and the lower elastic wheel is between the end of the connecting rod; According to this, the buffer setting for the two or two slave-type auxiliary shock absorption is provided to avoid the sudden rebound of the suspension caster as it rolls through the pothole, and Tiida improves the suspension capacity of the suspension caster. [Embodiment] A. About the purpose and effect of this creation The number of technical hands & sections used by the author and the structure of the "author" is better and practical, and the illustrations are as follows: First, please refer to the sixth figure. The suspension caster structure of this creation mainly includes: Fix the base body ⑴, the turn base (2), the chatter wheel (4) with the frame (3), the upper and lower elastic elements (5), (6), and the connecting rod, where: the fixed base body (1) The device is fixed on the bottom of the carrier (not shown in the cart); the swivel base (2) is a movable pivot located under the fixed base (work) for rotation use, and the swivel base (2) two The corresponding side has a position 4 (2 1) pivotally connected to the wheel frame (3), and a _ channel (2 2) is provided on the swivel base (2) for the connecting rod (7) to pass through and position; The wheel frame (3) is provided to support the pivoting caster wheel (4), and a pivot joint (3 workers) is provided at the position corresponding to the positioning part (2) # 2 of the swivel seat (2) for the swivel seat ( 2) Pivot combination, and the wheel frame (3) corresponding to the channel (2) of the turntable (2) is provided with long perforations (3 2); M267086 The upper and lower elastic elements ⑴, (6) are Respectively arranged on the wheel frame (3) with its long perforations 3 2) upper and lower positions, one end of the connecting rod (7) is provided with a removable nut (7 1), and the other end is provided with an integrally extending protrusion (7 2), and the lower elasticity The element (5) and the cymbal are positioned up-down at the turning seat and the wheel frame (3). Please refer to the seventh figure. Based on the design of the above structure, this creation has a shock-absorbing elastic structure. The link (7) is used to sleeve the lower element (6) from the bottom to the top and penetrate the wheel frame ( 3) Long perforation (3 2), so that the two ends of the lower elastic element (6) abut the top wheel frame (3) and the connecting rod (7 $ I # ® outlet (7 2), and the connecting rod (7) — The end is sleeved with an elastic element (5) and the dog is worn out of the channel (22) of the turntable (2), and the nut (7'-1) can be used to fix the connecting rod (7) to the turntable (2) ) Of the channel (2 2), so that the two ends of the upper elastic element (5) abut against the wheel frame (3) and the turntable (2) respectively; thereby forming a kind of auxiliary shock absorption buffer with upper and lower sections The set of shock-absorbing casters. Λ When the shock-absorbing caster passes over the ground with pits, the caster (4) will pull the wheel frame (3), so that the lower elastic element (6) is subjected to / compression " to absorb the casters ( 4) the pressure from the top of the pothole to the bottom, and when the caster (4) climbs from the bottom of the pothole to the top, the elastic element (5) above the wheel frame (3) will be compressed accordingly And absorb the elasticity accordingly, ( 6) The resilience of the spring, slowing down the rebound vibration force of the caster (4) passing through the bottom to the top of the pothole, so that the shock-absorbing caster can effectively perform balanced top-down shock absorption when it is = pothole, Trent's excellent 8 M267086 According to the above, it can be clearly known that the structure of this shock absorber caster uses the upper and lower two-stage complementary shock-absorbing cushioning settings to make the shock absorber casters in addition to cushion the heavy pressure stress above the vehicle 'It can also effectively absorb the vibration generated during the passage through the ground potholes', and then solve the problem of the sudden rebound of the conventional suspension casters due to the vibration through the potholes, which shows the substantial progress of the creation of the suspension casters. And industrial use value. In addition, as shown in the ninth figure, a brake device (8) may be provided between the wheel frame (3) and the turntable (2) for the suspension caster of this creation, so that the suspension caster Equipped with a brake positioning function. In summary, 'this creative embodiment can indeed achieve the expected use of function and the specific structure disclosed, not only has not been seen in similar products-= nor has it been disclosed before the towel, sincerely Fully qualified And-Mai Yi 3 patent application, please review it and grant the patent, then you will feel a sense of convenience.
