Technical Field

The utility model relates to a buffer oil pressure foot pad, in particular to a buffer oil pressure foot pad suitable for a supporting platform.

Background

When the desk is used in daily life, the individual desk legs of the desk are not landed and easy to shake due to the factors of uneven ground, errors of the desk legs, movement of the desk and the like, and if the desk is carelessly touched, articles on the desk can be overturned, so that people can feel restless. Currently, the existing foot pads on the market are generally divided into two types, one type is fixed, the other type is adjustable, and the height of the foot pads is adjusted by manually screwing nuts, so that the foot pads are very troublesome and the experience of users is poor.

Therefore, in order to achieve the self-balancing effect of the foot pad without manual adjustment of the balance, manufacturers have developed a buffering oil pressure foot pad similar to the present case in the past, such as the prior art disclosed in taiwan patent publication No. I605774B, however, in the prior art, the hydraulic cylinder is directly arranged on the regulator body, so that damping oil needs to be directly filled in the cylinder body of the regulator body, and a small gap needs to exist between the piston rod and the regulator body to ensure ventilation between the cylinder body and the inside and outside during the reciprocating motion of the piston rod, so that the risk of oil leakage is increased. In addition, the design of the upper side oil chamber and the lower side oil chamber used in the prior art can reduce the bearing capacity of the buffer oil pressure foot pad, can not bear heavier objects for a long time, is easy to break from the gap or the oil chamber, and is further easier to cause oil leakage.

The applicant has paid attention to the spirit of active creation, and has made a buffering oil pressure foot pad capable of solving the above problems, and has completed the present utility model through several research experiments.

Disclosure of Invention

The utility model mainly aims at providing the buffering oil pressure foot pad, and the structural design of the buffering oil pressure foot pad can ensure that a supporting platform provided with the foot pad does not need to manually adjust the balance, so that the balance of the supporting platform can be automatically adjusted in an effective range, and the stability of the supporting platform is ensured, and the supporting platform is not easy to shake. In addition, the self-balancing effect is achieved by matching the buffer damper with the gear and rack structure, and the damping oil is different from the buffer oil pressure foot pad which needs to be directly filled with damping oil in the foot pad body, so that the oil leakage can be effectively prevented, and longer time and larger bearing capacity are ensured.

In order to achieve the above objective, the buffering oil pressure foot pad of the present utility model is installed on a supporting platform, and comprises a foot pad body, a movable component, a buffering damper, a gear and a fixed connecting piece. The foot pad body is provided with a foot pad accommodating space. The movable part is provided with a rack which is accommodated in the foot pad accommodating space and is abutted against the foot pad body by a bearing spring. The cushion damper is assembled on the foot pad body, and damping oil is filled in the cushion damper. The gear is sleeved on the buffer damper and meshed with the rack. The fixed connecting piece is fixedly arranged on the movable part and used for connecting the supporting platform.

Through the design, the supporting force of the bearing spring and the buffer structure of the buffer damper are utilized, so that the flatness of the supporting platform can be adjusted within the effective adjusting height of the buffer oil pressure foot pad, namely, the supporting platform can be kept balanced and not swaying within the effective adjusting height, and even if a user touches the supporting platform carelessly by hands, the buffer oil pressure foot pad has a larger damping effect, and therefore, the buffer oil pressure foot pad cannot shake easily due to carelessly touching a table.

The foot pad body can comprise an upper cover and a lower cover, wherein the upper cover is assembled on the lower cover, and the foot pad body is formed by assembling two-piece structures.

The rubber pad can be arranged at the bottom of the lower cover, so that knocking abnormal sounds between the bottom of the buffer oil pressure foot pad and the ground can be reduced, and the buffer effect is achieved.

The movable part can be provided with a buckling hook, the inner surface of the foot pad body can be provided with a flange, and the buckling hook can be buckled on the flange. Therefore, when the buffer oil pressure foot pad is empty, the upper limit value of the adjusting height of the movable part can be limited against the elastic restoring force of the bearing spring.

The buffer damper can comprise a base, a top cover, blades and a sealing ring, wherein the top cover is provided with a through hole and is assembled on the base to form a damping accommodating space, the blades and the sealing ring are accommodated in the damping accommodating space, a rotating shaft of each blade protrudes out of the through hole and is sleeved with a gear, and damping oil is filled in the damping accommodating space. Therefore, the buffer damper can obtain dampers with different damping values by injecting damping oil with different viscosities, and meets the requirements of different buffer characteristics.

The fixing connecting piece can be a fixing screw. Therefore, the support platform can be locked on the support platform by using the fixing screws to assist in automatically adjusting the balance of the support platform.

In this embodiment, the support platform 1 is a table including a first support leg 11, a second support leg 12, a third support leg 13, and a fourth support leg 14, where the first support leg 11 and the second support leg 12 respectively mount the first fixed foot a and the second fixed foot b, and the third support leg 13 and the fourth support leg 14 respectively mount the first buffer oil pressure foot c and the second buffer oil pressure foot d. The first and second fixed foot pads a and b cannot be adjusted to be fixed ends, and the first and second buffer oil pressure foot pads c and d can be automatically adjusted to be movable ends. In the present embodiment, the effective adjustment height of the first buffer oil pressure pad c and the second buffer oil pressure pad d is 6mm (i.e. the supporting platform 1 can keep balance without shaking within the ground flatness fall of 6 mm), but the utility model is not limited thereto, and other values are also possible.

As shown in fig. 1, the first cushion hydraulic footpad c is in an extended state, which means that the ground is low, and the first cushion hydraulic footpad c is not compressed by force when not contacting the ground in the initial stage, so that the adjustment height is automatically increased until the first cushion hydraulic footpad c contacts the ground again, so as to maintain the flatness of the supporting platform 1; in contrast, the ground surface on which the second hydraulic cushion pad d is located is higher, and the adjustment height is automatically reduced to a balanced state due to the larger compression force given by the ground surface by the second hydraulic cushion pad d in the initial stage, so as to maintain the flatness of the support platform 1.

Fig. 2A to 5 are a perspective view, another perspective view, an exploded view, a sectional view and a sectional view of another perspective view of a cushion oil pressure pad according to a preferred embodiment of the present utility model. The first buffering oil pressure foot pad c comprises a foot pad body 2, a movable part 3, two buffering dampers 4, two gears 5 and a fixed connecting piece 6. The foot pad body 2 includes an upper cover 21, a lower cover 22 and two flanges 23, the upper cover 21 is assembled on the lower cover 22, and has a foot pad accommodating space 20, and the foot pad body 2 of the embodiment is formed by assembling the upper cover 21 and the lower cover 22 in two-piece structure, but not limited thereto, and may be an integral structure. Two flanges 23 are provided on the inner surfaces of the two sides of the footpad body 2, respectively. In addition, the rubber pad 221 is installed at the bottom of the lower cover 22, so as to reduce the knocking noise between the bottom of the first buffer oil pressure foot pad c and the ground, and achieve the buffer effect.

In addition, two racks 31 are disposed at positions of the movable part 3 corresponding to the two gears 5, the movable part 3 is accommodated in the foot pad accommodating space 20, and the bearing spring 32 abuts against the inner bottom of the lower cover 22 of the foot pad body 2 to provide elastic restoring force, so that the movable part 3 can perform linear displacement in the height direction in the foot pad accommodating space 20 to provide effective height adjustment. Furthermore, the two sides of the movable component 3 are respectively provided with a hook 33, so that when the first buffer oil pressure foot pad c is empty, the hook 33 can be buckled on the flange 23 for resisting the elastic restoring force of the bearing spring 32 and limiting the upper limit value of the adjusting height of the movable component 3.

Referring to fig. 6, an exploded view of a buffering damper according to a preferred embodiment of the present utility model is shown. As shown in the figure, the two buffer dampers 4 are respectively assembled on the upper cover 21 of the foot pad body 2, and comprise a base 41, a top cover 42, a blade 43 and a sealing ring 44, wherein the top cover 42 is provided with a through hole 421 and assembled on the base 41 to form a damping accommodating space 40, the blade 43 and the sealing ring 44 are accommodated in the damping accommodating space 40, a rotating shaft 431 of the blade 43 protrudes out of the through hole 421 and is sleeved with a gear 5, and the damping accommodating space 40 is filled with damping oil. Therefore, the buffer damper 4 can obtain buffer dampers with different damping values by injecting damping oil with different viscosities, so as to meet the requirements of different buffer characteristics, and the buffer damper 4 can achieve a damping effect no matter the blades 43 rotate clockwise or counterclockwise, namely, the bidirectional damping is realized. The assembly and finishing process of the damper 4 of the present utility model is generally as follows: after the base 41 is filled with damping oil, the blades 43 are placed in the damping accommodating space 40, then the sealing ring 44 and the top cover 42 are assembled, the base 41 and the top cover 42 are welded by ultrasonic after the assembly is completed, the buffer damper 4 with good sealing performance and the damping oil is not easy to leak out is formed, and the gear 5 sleeved on the rotating shaft 431 is meshed with the rack 31 positioned on the movable part 3 to transfer the damping characteristic.

Furthermore, the fixed connecting piece 6 is fixedly arranged on the movable component 3, and the fixed connecting piece 6 used in the embodiment is a fixed screw. Therefore, the first buffer oil pressure foot pad c can be locked on the supporting platform 1 by using the fixing screws to assist in automatically adjusting the balance of the supporting platform 1.

Referring to fig. 7A and 7B, internal state diagrams of the cushion oil pressure foot pad before and after compression according to a preferred embodiment of the present utility model are shown. As shown in fig. 7A, when the first cushion oil pressure foot pad c is in the unloaded state, the movable member 3 has not yet started to compress the load spring 32, at which time the maximum effective adjustment height D will be maintained. As shown in fig. 7B, when the first buffering oil pressure pad c is in a stressed state, the movable component 3 is stressed to compress the bearing spring 32 downwards, and at this time, the rack 31 of the movable component 3 drives the gear 5 to rotate in a homeotropic manner, but in this process, the buffering damper 4 provides the buffering force of the gear 5 to prevent the movable component 3 from sliding downwards rapidly, so that the self-balancing effect of the downward pressure and the spring force can be achieved progressively. Vice versa, when the stress of the first buffering oil pressure foot pad c is reduced or returns to the idle state, the spring restoring force of the bearing spring 32 will resist the movable part 3 to move upwards, and at this time, the rack 31 of the movable part 3 will drive the gear 5 to rotate in a clockwise direction, but in this process, the buffering damper 4 will provide the buffering force of the gear 5 to prevent the movable part 3 from rising rapidly, so that the self-balancing effect of the downward pressure and the spring force can be achieved progressively. Alternatively, the hook 33 of the movable component 3 may be locked to the flange 23 of the foot pad body 2, so as to limit the upper limit value of the height of the movable component 3 against the elastic restoring force of the bearing spring 32, and restore to the idle state.
