Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chairs, in particular to a combined pull-out chair. Background Art
[0002] The existing traditional chairs are bulky and inconvenient to move at home, especially in order to add rubber pads for protection and anti-skid on wooden boards or tiles, which makes the chair difficult to drag and move, and the whole chair is heavy to carry, so this case is proposed. Utility Model Content
[0003] The technical problem to be solved by the utility model is: in order to overcome the above problems, a combined pull-out chair is provided, which solves the above problems.
[0004] The utility model solves the technical problem by adopting the following technical solutions:
[0005] A combined pull-out chair comprises a chair and an auxiliary cavity arranged at the lower end of the chair support foot, a universal ball seat is arranged in the auxiliary cavity, a steel ball is rolled at the lower end of the universal ball seat for moving the chair, and a spring is arranged in the auxiliary cavity for pushing the universal ball seat downward.
[0006] Preferably, the elastic supporting force of the spring can only lift up the chair, that is, when a person sits down, the universal ball seat retracts into the auxiliary cavity to avoid sliding and ensure stability.
[0007] Preferably, a non-slip rubber foot pad for anti-slip and shock absorption is fixedly provided on the lower end surface of the supporting foot of the chair.
[0008] Preferably, grease is provided in the auxiliary cavity to facilitate the smooth up and down movement of the universal ball seat to avoid jamming.
[0009] Preferably, a sponge sleeve is provided on the outside of the universal ball seat, and grease is filled in the sponge sleeve, which can effectively increase the effective lubrication time and improve the service life.
[0010] Preferably, rubber gaskets are provided at both ends of the spring.
[0011] The advantages and positive effects of the utility model are: safety and stability. After a person sits down, the chair can be non-slip and fixed by the anti-slip rubber foot pad to protect the wooden floor tiles. When the person stands up, the spring lifts the chair so that the steel ball touches the ground, which is very convenient and labor-saving when dragging. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0013] Figure 1 It is a structural schematic diagram of the utility model;
[0014] Figure 2 yes Figure 1 Schematic diagram of the structure. DETAILED DESCRIPTION
[0015] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.
[0016] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:
[0017] like Figure 1-2 As shown, a combined pull-out chair described in the utility model includes a chair 10 and an auxiliary cavity 12 arranged at the lower end of the supporting foot of the chair 10, a universal ball seat 14 is provided in the auxiliary cavity 12, and a steel ball 15 is rolled at the lower end of the universal ball seat 14 for moving the chair, and a spring 13 is provided in the auxiliary cavity 12 for pushing the universal ball seat 14 downward.
[0018] Preferably, the elastic supporting force of the spring 13 can only lift up the chair 10, that is, when a person sits down, the universal ball seat 14 retracts into the auxiliary cavity 12 to avoid sliding and ensure stability.
[0019] Preferably, a non-slip rubber foot pad 16 for anti-slip and shock absorption is fixedly provided on the lower end surface of the supporting foot of the chair 10 .
[0020] Preferably, grease is provided in the auxiliary cavity 12 to facilitate the smooth up and down movement of the universal ball seat 14 to avoid jamming.
[0021] Preferably, a sponge sleeve 17 is provided on the outside of the universal ball seat 14, and grease is filled in the sponge sleeve 17, which can effectively increase the effective lubrication time and improve the service life.
[0022] Preferably, rubber gaskets are provided at both ends of the spring 13 .
[0023] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manner derived by those skilled in the art based on the technical solution of the present invention also falls within the scope of protection of the present invention.
