Description

Technical Field

[0001] This utility model relates to a support leg, and more specifically, to a movable support leg with retractable rollers. Background Technology

[0002] For some furniture products, rollers are usually installed on the bottom of the furniture to facilitate movement and handling. At the same time, in order to maintain stability when movement is not required, a braking structure is also installed on the rollers. The braking structure locks the rollers in place by friction, so as to prevent the rollers from rolling and keep the furniture in a stable position.

[0003] However, in current furniture products, the roller components still produce a slight wobbling even when the brake is locked, which prevents the furniture from being stably supported. Especially when the brakes on the roller components are worn, the braking effect will be further reduced, which may cause more wobbling.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a retractable movable support foot with a roller.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a roller-type movable support foot, including a cylindrical support member, the cylindrical support member having an upper end and a lower end, the upper end being fixedly connected to a connecting block, and the lower end forming an opening;

[0007] It also includes a lifting block and rollers. The lifting block is installed inside the cylindrical support member and can slide up and down along the cylindrical support member to adjust its position. It has an upward adjustment position and a downward adjustment position. A spring is elastically pressed between the upper side of the lifting block and the connecting block. The rollers are installed on the lower side of the lifting block. When the lifting block is in the upward adjustment position, the rollers are retracted into the cylindrical support member. When the lifting block is in the downward adjustment position, the rollers can at least partially protrude from the lower end of the support member.

[0008] The present invention is further configured such that the lifting block has a horizontally arranged through hole, an adjusting block is slidably connected in the through hole, and the adjusting block has a protrusion integrally connected in the direction of the outer periphery of the cylindrical support member.

[0009] The cylindrical support member has a lower limit hole and an upper limit hole. The protrusion can be inserted into the lower limit hole and the upper limit hole respectively to achieve the limit. The protrusion can extend out of the cylindrical support member.

[0010] The present invention is further configured such that adjusting blocks are respectively installed at both ends of the through hole, and a spring is elastically pressed between the two adjusting blocks.

[0011] The present invention is further configured such that two lower limit holes and two upper limit holes are symmetrically arranged and correspond to two adjusting blocks respectively.

[0012] The present invention is further configured such that a wheel seat is rotatably connected to the lower side of the lifting block via a rotating shaft, and the roller is rotatably mounted on the wheel seat.

[0013] The present invention is further configured such that the axis of the rotating shaft is vertically arranged up and down, and the axis of the roller is horizontally arranged.

[0014] The present invention is further configured such that, when the lifting block is in the upward position, the protrusion is embedded in the upper limit hole; when the lifting block is in the downward position, the protrusion is embedded in the lower limit hole.

[0015] The present invention is further configured such that the upper limit hole is an oblong hole and runs vertically, the upper side of the inner periphery of the upper limit hole forms an upper edge, and the lower side of the inner periphery forms a lower edge; the protrusion can slide and adjust between the upper edge and the lower edge.

[0016] The present invention is further configured such that when the protrusion is embedded in the upper limit hole and abuts against the lower side edge, the lower side portion of the roller protrudes from the lower end.

[0017] The present invention is further configured such that when the protrusion is embedded in the upper limit hole and abuts against the upper side edge, the roller is fully retracted into the lower end.

[0018] In summary, this utility model has the following beneficial effects:

[0019] By installing rollers inside a hollow cylindrical support, the rollers can be adjusted up and down within the support. When the rollers are adjusted to the upward position, they retract into the support, at which point the lower end of the support directly supports the ground, ensuring stability. When movement is required, the rollers can be lowered relative to the support, allowing the support to extend from its lower end, with the rollers directly contacting the ground. This allows for rolling adjustment using the rollers, facilitating the movement of furniture and other items. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This embodiment discloses a retractable movable support foot with a roller, see reference. Figures 1-4 As shown, it includes a cylindrical support member 1, which is generally cylindrical in shape; the cylindrical support member 1 has an upper end 11 and a lower end 12, a connecting block 2 is fixedly connected to the upper end 11, the connecting block 2 can be connected to the bottom of the furniture to realize the installation of the support legs; an opening is formed at the lower end 12, and the opening at the lower end 12 can be used for the extension and retraction adjustment of the roller 5.

[0030] The retractable movable support foot of the roller in this embodiment also includes a lifting block 3 and a roller 5. The outer periphery of the lifting block 3 is adapted to the inner periphery of the cylindrical support 1 and is installed inside the cylindrical support 1. The lifting block 3 can slide up and down along the cylindrical support 1 and has an upward adjustment position and a downward adjustment position.

[0031] The roller 5 is installed on the lower side of the lifting block 3 and can adjust accordingly as the lifting block 3 rises and falls. When the lifting block 3 is in the upward position, the roller 5 is retracted into the cylindrical support member 1, and the lower end 12 of the cylindrical support member 1 directly contacts the bottom surface, which can stably support the furniture; when the lifting block 3 is in the downward position, the roller 5 can at least partially protrude from the lower end 12 of the support member 1, and the roller 5 rolls in contact with the ground, which can facilitate the sliding adjustment of the furniture.

[0032] A limiting structure is installed on the lifting block 3 and the cylindrical support 1 to limit their positions, thereby maintaining them in the corresponding upward and downward positions.

[0033] Specifically, a horizontally arranged through hole 31 is provided in the lifting block 3, and an adjusting block 32 is slidably connected in the through hole 31. The adjusting block 32 is connected to a protrusion 33 in the direction of the outer periphery of the cylindrical support member 1. The adjusting block 32 and the protrusion 33 are integrally connected, and the outline size of the protrusion 33 is slightly smaller than that of the adjusting block 32.

[0034] The cylindrical support 1 has a lower limit hole 13 and an upper limit hole 14, with the lower limit hole 13 located below the upper limit hole 14. When the lifting block 3 is adjusted up and down within the cylindrical support 1, the protrusion 33 engages with different lower limit holes 13 and upper limit holes 14, thereby achieving positioning. In the upward position, the protrusion 33 is embedded in the upper limit hole 14; in the downward position, the protrusion 33 is embedded in the lower limit hole 13.

[0035] Two lower limit holes 13 and two upper limit holes 14 are symmetrically arranged, that is, four limit holes are formed on the outer periphery of the cylindrical support member 1. One lower limit hole 13 and one upper limit hole 14 form a group, which are distributed vertically. During the vertical movement of the adjusting block 32, it can be aligned with the lower limit hole 13 and the upper limit hole 14. The protrusion 33 of the adjusting block 32 falls into the corresponding limit hole to form a locking limit.

[0036] Adjusting blocks 32 are installed at both ends of the through hole 31, i.e., there are two adjusting blocks 32. A spring 34 is elastically pressed between the two adjusting blocks 32. The spring 34 is embedded in the through hole 31 and its two ends are respectively limited by the elastic blocking of the two adjusting blocks 32.

[0037] When the protrusion 33 of the adjusting block 32 is misaligned with both the lower limit hole 13 and the upper limit hole 14, the protrusion 33 is confined within the cylindrical support 1 and is limited by the inner wall of the cylindrical support 1, while the spring 34 is compressed. When the protrusion 33 moves to the corresponding lower limit hole 13 or upper limit hole 14, the protrusion 33 can be inserted into the corresponding limit hole, and the protrusion 33 can extend through the limit hole to the outside of the cylindrical support 1. The protrusion 33 can be partially exposed on the outer periphery of the cylindrical support 1, thus facilitating pressing and adjustment of the protrusion 33, enabling both to be unlocked, and facilitating the storage and extension adjustment of the roller 5.

[0038] A second spring 6 is elastically pressed between the upper side of the lifting block 3 and the connecting block 2. The second spring 6 is located on the inner circumference of the cylindrical support member 1. The second spring 6 can apply a downward elastic force to the lifting block 3. After the protrusion 33 and the corresponding limiting hole unlock each other, the lifting block 3 can slide within the cylindrical support member 1.

[0039] For the installation of roller 5, this embodiment uses wheel seat 4 to connect roller 5 to lifting block 3. Wheel seat 4 is installed on the underside of the bottom surface 301 of lifting block 3. Wheel seat 4 is rotatably connected to lifting block 3 via a rotating shaft 41, and the axis of the rotating shaft 41 is vertically aligned with the sliding direction of lifting block 3. The roller 5 allows for convenient adjustment of its rolling motion, improving adjustment flexibility.

[0040] The wheel seat 4 has a mounting groove 42, and the roller 5 is located in the mounting groove 42 and is rotatably connected to the wheel seat 4 via a wheel axle. The roller 5 can achieve smooth rotation adjustment, and the axis of the roller 5 is set horizontally, allowing it to roll with the ground.

[0041] This embodiment also discloses another type of retractable movable support foot with rollers, which is based on the above embodiment and further refers to... Figures 5-7 Please provide a detailed explanation.

[0042] In this embodiment, the upper limit hole 14 is an oblong hole and runs vertically. The width of the upper limit hole 14 is slightly larger than that of the protrusion 33, allowing the protrusion 33 to be smoothly inserted into the upper limit hole 14. The height of the upper limit hole 14 is greater than that of the protrusion 33.

[0043] Reference Figure 6 As shown, the upper edge 141 is formed on the upper inner periphery of the upper limit hole 14, and the lower edge 142 is formed on the lower inner periphery; the protrusion 33 can slide and adjust between the upper edge 141 and the lower edge 142, thereby enabling the lifting block 3 and the roller 5 to form a small height adjustment space when the lifting adjustment is to the upper position.

[0044] Reference Figure 7As shown, when the protrusion 33 is inserted into the upper limit hole 14 and abuts against the lower edge 142, the lower part of the roller 5 protrudes from the lower end 12. When the protrusion 33 is inserted into the upper limit hole 14 and abuts against the upper edge 141, the roller 5 is completely retracted into the lower end 12.

[0045] In this embodiment, the retractable movable support legs are typically installed at the bottom of the furniture, which has a certain weight; see reference. Figure 5 As shown, when the roller 5 is not needed for movement and adjustment, the roller 5 retracts into the cylindrical support 1. At this time, the protrusion 33 is embedded in the upper limit hole 14 and is approximately located in the middle of the upper limit hole 14. Under the elastic action of the second spring 6, the roller 5 is kept in contact with the ground.

[0046] When the roller 5 needs to be moved and adjusted, the furniture can be lifted appropriately and the protrusion 33 can be pressed. After the protrusion 33 is retracted into the upper limit hole 14, under the elastic action of the spring 6, the lifting block 3 will slide down and adjust until the protrusion 33 is opposite to the lower limit hole 13 and is embedded in the lower limit hole 13. At this time, the roller 5 on the lower side of the lifting block 3 can be exposed at the lower end 12 of the cylindrical support 1, and the roller 5 can roll and contact the ground, making it convenient to move the furniture.

[0047] When the roller 5 needs to be stored, the furniture can be lifted appropriately, and the protrusion 33 can be pressed down. After the protrusion 33 retracts into the lower limit hole 13, the furniture can be lowered, and the roller 5 will contact the ground. Under the weight of the furniture, the elasticity of the spring 6 can be overcome, and the lifting block 3 and the roller 5 can move upward relative to the cylindrical support 1, and the roller 5 can retract into the cylindrical support 1. Since the upper limit hole 14 is an oblong hole with a certain length in the vertical direction, the protrusion 33 will be pre-retracted into the upper limit hole 14 before the lower end of the cylindrical support 1 abuts against the ground, ensuring that the protrusion 33 can be locked and limited by the upper limit hole 14; see reference. Figure 7 As shown, as the cylindrical support 1 continues to descend, the roller 5 can contact the ground, and the spring 6 can provide a buffering effect in the final stage of clamp placement, preventing the clamp from suddenly falling and colliding. Finally, the lower end of the cylindrical support 1 is supported by contact with the ground.

[0048] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
