Description

Technical Field

[0001] The utility model belongs to the technical field of profiles, and specifically relates to a column profile. The utility model also relates to a frame structure and a medical cart using the column profile. Background Art

[0002] In the fields of furniture and equipment manufacturing, profiles can be used as columns, on which various components are further connected to form a frame, and then panels and equipment are overlapped on the frame to form products. Column profiles are usually used as support points in frame structures, and notches are set on column profiles for connecting other components.

[0003] In the prior art, other components are generally connected to column profiles in two ways. One is to drill holes in the column profile, and other components are directly connected to the column profile through bolts. The accuracy of manual drilling is limited, and inaccurate hole positions may cause difficulties in product assembly. Using CNC machine tools for drilling can ensure processing accuracy, but CNC machine tools are expensive, and some downstream manufacturers that provide customized services do not have the processing conditions. In order to ensure that there are no problems during installation, it is often necessary to overlap the frame and then send it out in the form of a frame, resulting in large shipping volume and high logistics costs. In addition, the exposed bolts are not beautiful, and when the material of the column profile is not corrosion-resistant, rust will also begin to occur from the screw holes.

[0004] Another approach is to insert other components directly into the notch of the column profile, and limit the displacement of the component by matching the notch with the shape of the component edge, but this requires customization of the column profile and / or component, and places high demands on processing accuracy. In order to remove customization, this approach has another variant, that is, connecting a slider at the end of the component, and the shape of the slider matches the notch. However, in the prior art, the component and the slider are generally connected by bolts, and the opening direction of the notch is parallel to the extension direction of the component. This structure will cause the component to be connected to the slider in the thickness direction, and the tightness is difficult to adjust. It is time-consuming and laborious to install, and requires high installation skills from the installer. The notch and the component cannot be perfectly fitted, which leads to customers questioning the quality of the product. In addition, when the length range of the component does not cover the entire notch, the notch section without the component is exposed, affecting the appearance of the product.

[0005] In summary, the column profile in the prior art has the problem that it is not possible to connect components of different thicknesses conveniently and beautifully. Utility Model Content

[0006] In order to solve the above technical problems, it is necessary to provide a column profile that can cooperate with a slider to connect components of different thicknesses conveniently and beautifully.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A column profile comprises a first wall surface and a second wall surface arranged at an angle, and also comprises a connecting inner rib connecting the first wall surface and the second wall surface, wherein the connecting inner rib and the first wall surface and the second wall surface surround to form a structural hole, a first notch is arranged on the inner surface of the first wall surface on the outer side of the connecting inner rib, and the opening direction of the first notch is perpendicular to the first wall surface, and a second notch is arranged on the inner surface of the second wall surface on the outer side of the connecting inner rib, and the opening direction of the second notch is perpendicular to the second wall surface.

[0009] In the column profile provided by the utility model, at least one connecting inner rib is arranged between the first wall surface and the second wall surface, and the connecting inner rib, the first wall surface and the second wall surface together form the column shape. A notch with an opening direction perpendicular to the first wall surface is arranged on the inner surface of the first wall surface, and when viewed from the outside of the column profile, i.e., the outside of the first wall surface and the second wall surface, the first notch is hidden inside the first wall surface, and similarly, the second notch is hidden inside the second wall surface; after inserting a slider into the notch, the component can be connected to the column profile through the slider, and since the component is generally linear, the notch direction is set to be perpendicular to the wall surface so that the component is parallel to the wall surface, and the gap between the component and the column profile can be eliminated by fitting and pressing, and the wall surface direction of the component and the column profile is consistent, and the line is smoother after connection. The general connection method is to set a screw hole on the slider, and the bolt penetrates the component to be connected and cooperates with the screw hole to connect. Since the bolt insertion direction is in the thickness direction of the component, and the edge of the component is located above the notch instead of inside, the thickness of the component is not limited by the width of the notch mouth, and the production of a column profile of one specification can be suitable for connecting components of various thicknesses; since the bolt is inserted from the mouth of the notch to the bottom, compared with the prior art, the action process when tightening the bolt will not be hindered by the structure, making the operation more convenient, and the tightness between the slider and the component no longer affects the installation process, while the tightness between the slider and the component in the prior art will affect the length of the component and the slider after connection, and the bolt cannot be tightened after the slider is installed in the notch, and it needs to be taken out for adjustment, resulting in installation difficulties; when the screw hole is a through hole, the end of the bolt can be further made to abut against the bottom of the notch to lock the slider, while in the prior art, if the component is to be load-bearing, it is necessary to add bolts for fixing. The column profile provided by the utility model can be connected with components of different thicknesses in conjunction with a slider, and the position of the component can be freely adjusted and fixed. It is not easy to leave a gap at the joint between the column profile and the component, and the requirement for installation accuracy is reduced, making installation more convenient.

[0010] Preferably, the first notch is a C-shaped notch, one end of the notch mouth extends from the outer surface of the connecting inner rib, and the other end is formed by the end of the first wall surface hooking back. In this structure, the first notch is arranged close to the connecting inner rib, and a part of the outer surface of the connecting inner rib is also the inner surface of the first notch, so that the overall volume of the column profile is small, the structure is simplest, and it is not easy to deform.

[0011] Preferably, the root of the connecting inner rib located in the first notch is in a triangular wedge shape. This structure strengthens the ability of the column profile to resist deformation. Since the notch is not arranged on the main body of the column profile composed of the connecting inner rib and the first wall surface and the second wall surface but is arranged on the side of the main body, the notch may be bent relative to the main body when subjected to force, and the ability of the structure to resist deformation is improved by thickening the root of the connecting inner rib.

[0012] Preferably, the outer surface of the connecting inner rib includes a first plane perpendicular to the first wall surface, a second plane perpendicular to the second wall surface, and a third plane connecting the first plane and the second plane. In this structure, the outer surface of the connecting inner rib includes at least three planes. The first plane perpendicular to the first wall surface and the second plane perpendicular to the second wall surface ensure the structural reinforcement of the connecting inner rib. The third plane connecting the first plane and the second plane is used to connect other components. The plane structure is convenient for bolting.

[0013] Preferably, a step surface is provided on the outer surface of the first notch, and the step surface is used to buckle the flat seal. In the prior art, there are flat seals that can seal the notch of unconnected components to prevent dirt. The step surface is provided to offset the thickness of the top surface of the flat seal, so that the edge of the flat seal is flush with the outer surface of the notch after buckling into the notch, and the flat seal is more firmly and beautifully engaged.

[0014] A frame structure includes at least three vertically arranged column profiles as described above, wherein the cross sections of the first wall surface and the second wall surface of all the column profiles are located on the same convex polygon. Since it includes the column profiles as described above, the frame structure has all the beneficial technical effects brought by the column profiles, which will not be described one by one here.

[0015] Preferably, it further comprises at least one plate parallel to the ground, and all the column profiles are connected to the plate.

[0016] A medical cart comprises a body and a caster assembly connected to the bottom of the body, wherein the body comprises the frame structure as described above. Since the cart comprises the frame structure as described above, the cart has all the beneficial technical effects brought by the frame structure, which will not be described one by one here.

[0017] Preferably, the caster assembly includes a caster seat, a connecting column arranged on the top surface of the caster seat, and a caster connected to the bottom of the caster seat, and the connecting column is used to be inserted into the structural hole of the column profile from the bottom, so that the caster assembly and the column profile are detachably connected. In this structure, the caster assembly is plugged into the column profile, which is convenient for caster connection, and because the caster is arranged at the bottom of the column profile as a structural support point, the structure of the medical cart is relatively stable.

[0018] Preferably, it also includes a table top arranged on the top of the vehicle body, and a mounting post that penetrates the table top from top to bottom and extends into the structural hole. In this structure, the mounting post penetrates the table top and extends into the structural hole, which facilitates the addition of accessories on the table top to meet the needs of medical scenarios.

[0033] In a preferred embodiment, the root of the connecting inner rib 5 located in the first notch 3 is in a triangular wedge shape. This structure strengthens the ability of the column profile to resist deformation. Since the notch is not provided on the main body of the column profile composed of the connecting inner rib 5 and the first wall 1 and the second wall 2 but is provided beside the main body, the notch may be bent relative to the main body when subjected to force, and the ability of the structure to resist deformation is improved by thickening the root of the connecting inner rib 5.

[0034] In a preferred embodiment, the outer surface of the connecting inner rib 5 includes a first plane 51 perpendicular to the first wall 1, a second plane 52 perpendicular to the second wall 2, and a third plane 53 connecting the first plane 51 and the second plane 52.

In other embodiments, there may be three vertically arranged column profiles, all of which are located on the same triangle, or there may be six vertically arranged column profiles, all of which are located on the same convex hexahedron. In this case, the outer surfaces of the first wall 1 and the second wall 2 are both facing outward, while the opening direction of the notch is toward a position that is difficult to observe in the center of the frame. In a preferred embodiment, the angle between the first wall 1 and the second wall 2 is a right angle. In other embodiments, it can be set arbitrarily according to requirements.
