Description

Technical Field

[0001] The utility model relates to the technical field of bearing human bodies, in particular to a drawer-type bearing mechanism. Background Art

[0002] When people need to take out objects placed at a high place on a furniture cabinet, they often use a ladder or a stool, and they step on the ladder or the stool to take out the objects at a high place on the furniture cabinet, which is time-consuming and laborious for people to move the ladder or the stool.

[0003] The existing method is to set the load-bearing mechanism to be movable and retractable on the cabinet. When the load-bearing mechanism is needed, it is pulled out from the cabinet. When it is not needed, it is stored in the cabinet like a drawer. However, when the load-bearing mechanism is pulled out from the outer end of the cabinet, one end of the load-bearing mechanism can be supported on the moving rail, and the other end of the load-bearing mechanism needs to be provided with a supporting foot. The supporting foot contacts the supporting surface (ground) when the load-bearing mechanism is in the load-bearing state. Therefore, when the load-bearing mechanism needs to be stored in the cabinet, the load-bearing mechanism will drive the supporting foot to slide, so that the supporting foot will rub against the ground during the sliding process to produce abnormal noise, causing wear on the bottom of the supporting foot.

[0004] In order to solve the above technical solution, a caster is provided for the supporting foot, and the caster is relatively large, so the accommodating space of the cabinet for the load-bearing mechanism is increased, which will lead to an increase in production costs. Utility Model Content

[0005] The utility model aims to provide a drawer-type load-bearing mechanism, which elastically floats a support plate assembly on a moving rail. When the support plate assembly is in a non-load-bearing pending state, the support plate assembly floats on the moving rail due to elasticity. In this way, when the support plate assembly is pulled on the cabinet, the bottom of the supporting foot piece will not contact the supporting surface, thereby avoiding sliding friction between the supporting foot piece and the supporting surface during the storage process of the support plate assembly, thereby playing an anti-wear role.

[0006] The purpose of the utility model is achieved in this way:

[0007] A drawer-type load-bearing mechanism includes a movable rail for supporting a support plate assembly, an elastic assembly is provided between the support plate assembly and the movable rail, the support plate assembly is elastically floated up and down on the movable rail by the elastic assembly, and when the support plate assembly is in a load-bearing state, the elastic assembly elastically limits and deforms between the support plate assembly and the movable rail.

[0008] The support plate assembly floats on the moving rail due to its elasticity, so when the support plate assembly is pulled on the cabinet, the bottom of the supporting leg will not contact the supporting surface, thereby preventing the supporting leg from sliding and rubbing against the supporting surface during the storage of the support plate assembly, thereby playing an anti-wear role. When the support plate assembly is in a load-bearing state, the elastic assembly is compressed and the supporting leg will contact the supporting surface.

[0009] An elastic component is arranged between the front and rear ends of the support plate assembly and the moving rail; when the support plate assembly switches from a load-bearing state to a non-load-bearing pending state, the front and rear ends of the support plate assembly are synchronously elastically reset through the elastic component.

[0010] The support plate assembly can be provided with only an elastic assembly at its front end (because the supporting foot is located on the front end of the support plate assembly), and the rear end of the support plate assembly can be fixed on the moving rail. However, in this way, only the front end of the support plate assembly will float up and down elastically, and under long-term use, the support plate assembly will deform.

[0011] Therefore, the preferred solution is to provide elastic components at the front and rear ends of the support plate assembly. The support plate assembly switches from a load-bearing state to a non-load-bearing pending state, and the front and rear ends of the support plate assembly are elastically reset synchronously through the elastic components, thereby solving the technical problem that only the front end of the support plate assembly is elastically floating and prone to deformation.

[0012] One end of the elastic component at the rear end is provided with a first connecting portion fixedly connected to the support plate assembly, and the other end of the elastic component at the rear end is provided with a second connecting portion detachably connected to the movable rail. Since the rear end of the support plate assembly is prone to warping when a human body stands on the support plate assembly, one end of the elastic component at the rear end is fixed to the support plate assembly, and the other end of the elastic component is fixed to the movable rail. On the one hand, the support plate assembly and the movable rail can be indirectly connected, and on the other hand, the rear end of the support plate assembly can be prevented from easily warping, thereby avoiding displacement of the elastic component at the rear end of the support plate assembly.

[0013] A groove is provided on the support plate assembly, one end of the elastic assembly is limitedly installed on the groove, and the other end of the elastic assembly is supported on the movable rail, so that the elastic assembly is limited up and down between the support plate assembly and the movable rail.

[0014] The elastic component includes a fixed part, a movable part, and an elastic part. The fixed part is limitedly installed on the support plate assembly. A movable limiting matching part is provided between the fixed part and the movable part. The elastic part is arranged between the fixed part and the movable part. The movable part is elastically limited on the fixed part by the elastic part and the movable limiting matching part to prevent the movable part from detaching from the fixed part.

[0015] The support plate assembly includes a supporting foot located above the supporting surface; the support plate assembly is in a non-load-bearing pending state, the supporting foot does not act on the supporting surface and has a suspended distance L1 between the supporting surface, so that when the support plate assembly is pulled on the cabinet, the bottom of the supporting foot will not contact the supporting surface, thereby avoiding sliding friction between the supporting foot and the supporting surface during the storage of the support plate assembly, thereby playing an anti-wear role.

[0016] The supporting foot piece is provided with an adjusting member for adjusting the suspension distance L1 between the supporting foot piece and the supporting surface. The adjusting member is telescopically arranged on the supporting foot piece up and down. When the adjusting member moves up and down, the telescopic position of the adjusting member on the supporting foot piece is changed.

[0017] When the support plate assembly is in a load-bearing state and there is still a suspension distance L1 between the support foot and the support surface, it can be adjusted by the adjusting member. When the adjusting member moves downward, it can act on the support surface to compensate for the suspension distance L1 between the support foot and the support surface.

[0018] The support plate assembly includes a support plate. The support plate assembly is in a non-load-bearing pending state. The support plate does not act on the movable rail and has an up-and-down floating spacing L2 with the movable rail.

[0019] The support plate is provided with a support reinforcement member for increasing its load-bearing strength.

[0020] The movable rail is slidably arranged on the fixed rail, and the fixed rail is arranged on the cabinet body; when the support plate assembly is in a non-load-bearing waiting state, the support plate assembly reciprocates on the fixed rail of the cabinet body through the movable rail.

[0021] The beneficial effects of the utility model are as follows:

[0022] The support plate assembly is elastically floated up and down on the moving rail by the elastic assembly. When the support plate assembly is in a load-bearing state, the elastic assembly elastically limits and deforms between the support plate assembly and the moving rail. The support plate assembly floats on the moving rail due to its elasticity, so that when the support plate assembly is pulled on the cabinet, the bottom of the support foot piece will not contact the support surface, avoiding sliding friction between the support foot piece and the support surface during the storage process of the support plate assembly, thereby playing an anti-wear role. When the support plate assembly is in a load-bearing state, the elastic assembly is compressed, and the support foot piece will contact the support surface. BRIEF DESCRIPTION OF THE DRAWINGS
