Description

Technical Field

[0001] The utility model relates to the technical field of directional wheels and provides a reinforced directional wheel with a shock absorbing structure. Background Art

[0002] Fixed wheels are widely used in various equipment and tools that require flexible movement and steering, such as refrigerators and industrial equipment. However, existing fixed wheel designs have some significant shortcomings that affect their service life and performance.

[0003] First, the directional wheels currently on the market usually lack effective shock absorption mechanisms. This results in the inability of the directional wheels to effectively absorb shock and vibration on uneven surfaces or in environments with obstacles, which in turn affects the smooth operation of the equipment and increases the risk of wear and damage to the equipment and the directional wheels themselves. For example, in industrial applications, equipment often needs to move on rough ground, and the existing directional wheel design cannot effectively alleviate the impact in such an environment, resulting in unstable equipment operation and affecting production efficiency and safety.

[0004] Secondly, the existing directional wheel structure is prone to deformation when subjected to lateral force. This deformation not only reduces the bearing capacity of the directional wheel, but may also cause the wheel body to get stuck and turn inflexibly, and in severe cases even cause the directional wheel to fail. This defect is particularly obvious in application environments with frequent turns or large lateral forces. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a reinforced directional wheel with a shock absorbing structure, comprising:

[0006] A bracket, the bracket comprising a mounting plate and supporting arms arranged on both sides of the mounting plate, wherein a slide groove is arranged in the supporting arm to provide a shock-absorbing displacement margin for the directional wheel;

[0007] A directional wheel, wherein the directional wheel is arranged between the two supporting arms, and a wheel axle is arranged at the axis of the directional wheel, and the wheel axle passes through the slide groove, and the wheel axle can slide along the slide groove;

[0008] The shock absorbing mechanism is arranged at the slide groove and fixedly installed on the outside of the support arm, including a sleeve, a spring is arranged in the sleeve, one end of the spring is connected to the sleeve, and a slider is arranged at the other end of the spring.

[0013] Specifically, mounting holes are arranged at four corners of the mounting plate.

[0014] Specifically, the bottom of the sliding block is in an arc shape, matching the shape of the wheel axle.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model introduces a shock-absorbing mechanism in the directional wheel, which can effectively absorb shock and vibration during the movement of the equipment, especially on uneven surfaces or in environments with obstacles, significantly improving the stability and operating efficiency of the equipment and reducing the wear and damage of the directional wheel and the equipment.

[0017] 2. The utility model optimizes the design of the bracket structure, arranges reinforcing ribs at the bending part of the support arm and the mounting plate, and arranges outwardly extending extensions at both ends of the bending part, which can greatly improve the deformation resistance of the directional wheel when subjected to lateral force.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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. The specific implementation of the utility model is described in detail below in combination with specific embodiments.

[0025] like Figure 1-Figure 4 As shown, the utility model provides a reinforced directional wheel with a shock absorbing structure, comprising a bracket and a directional wheel 6 installed in the bracket, wherein the bracket comprises a mounting plate 1 and support arms 2 arranged on both sides of the mounting plate 1 .

[0026] The mounting plate 1 is provided with mounting holes 11, which are arranged at the four corners of the mounting plate 1. The directional wheel 6 can be installed at the bottom of the transport frame and other equipment by bolts. The arm 2 is bent and arranged on both sides of the mounting plate 1. A reinforcing rib 4 is arranged at the bend of the arm 2. An extension 5 extending outward is arranged at both ends of the bend, so that the arm 2 increases the extension amount extending outward. The arrangement of the reinforcing rib 4 and the extension 5 strengthens the strength of the structure, which can significantly improve the moment of inertia of the arm 2 and the deformation resistance of the directional wheel 6 when the equipment is turned and subjected to lateral force. Even if the directional wheel 6 turns frequently or is subjected to a large lateral force, the arm 2 structure can still remain stable and is not easy to deform, avoiding the common problems of jamming and failure in the prior art. The two sides of the arm 2 are provided with triangular bent plates 21 bent outward to increase the strength of the arm 2 and prevent the arm 2 from deforming during use.

[0027] The directional wheel 6 is arranged between the two arms 2, and includes a wheel body 61. Slots are arranged on both sides of the wheel body 61, and wrist guards 62 are engaged in the slots. A sleeve 63 and a wheel axle 64 sleeved in the sleeve 63 are arranged at the axis of the directional wheel 6. The sleeve 63 is arranged between the two wrist guards 62, and the wheel axle 64 passes through both sides of the wrist guard 62.

[0028] A slide groove 22 is opened in the support arm 2 along the vertical direction, and the shock absorbing mechanism 3 is arranged at the slide groove 22 and welded to the outer side of the support arm 2. The shock absorbing mechanism 3 includes a sheath 31, and a spring 32 is arranged in the sheath 31. One end of the spring 32 is fixedly connected to the sheath 31, and a slider 33 is arranged at the other end of the spring 32. The slider 33 is connected to the spring 32. The shield wraps the spring 32 and the slider 33 therein to protect the shock absorbing mechanism 3 and limit the movement of the spring 32 and the slider 33. The slider 33 can slide in the sheath 31 along the length direction of the sheath 31.

[0029] The wheel axle 64 passes through the slide groove 22 and is engaged in the sleeves 31 on both sides. The wheel axle 64 abuts against the bottom of the slider 33. The bottom of the slider 33 is arc-shaped, matching the shape of the wheel axle 64. The wheel axle 64 can slide along the slide groove 22, and the slide groove 22 provides a shock-absorbing displacement margin for the directional wheel 6. When the equipment is moving, especially when it moves on rough ground or ground with obstacles, the impact and vibration of the bottom caster are transmitted to the shock-absorbing mechanism 3 through the wheel axle 64. The spring 32 absorbs the impact and vibration and deforms, reducing the vibration amplitude of the equipment, significantly improving the stability and operating efficiency of the equipment, and reducing the wear and damage of the directional wheel 6 and the equipment due to bumps.

[0030] By improving the structure of the support arm 2 and adding a shock absorbing mechanism 3, it can be ensured that the equipment can operate stably in various complex application environments, which not only improves the operating efficiency of the equipment, but also increases the safety of the equipment and reduces the operating risks.
