Description

Handrail with clamping function

Technical Field

The utility model relates to a handrail especially relates to a handrail with clamping function, belongs to handrail technical field.

Background

In the decoration of stairs, there is a supporting structure using glass or other plate-like materials as a supporting member under a handrail, and the installation of the structure requires that a clamping groove is arranged under the handrail and glue is injected to clamp the glass or plate-like materials.

For example, chinese patent No. CN 203603384U discloses a solid wood handrail sheet clip on a glass balustrade panel, which has a typical structure: handrail face and be used for the centre gripping groove of centre gripping glass.

In order to save cost, the handrail in the prior art is often formed by gluing three density boards, referring to the attached drawing 1 in the specification, one density board in the middle is dug out to form a clamping groove, the binding force between the glued boards of the handrail under the action of glass or other boards is limited, the structure is easy to scatter after long-term use, and the service life is limited.

And the existing handrail with the structure can not eat nails and is not easy to operate under the condition that further reinforcement is needed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses above-mentioned technical problem will be solved to a handrail with clamping function is provided, has that intensity is good, long service life and can eat the advantage of nail.

The utility model provides a technical scheme as follows of above-mentioned problem:

handrail with clamping function, its characterized in that contains:

an outer cover;

an inner cover disposed at an opposite side of the outer cover;

a support portion disposed between the outer cover and the inner cover;

and the clamping groove is formed on the surface of the inner covering part.

When centre gripping glass or panel, fix glass or panel through injecting glue in to the centre gripping inslot, through the supplementary fixed glass of the cohesion of interior covering part material self or plate-like material, strengthened the bulk strength of handrail.

Preferably, in the above aspect, the holding groove is formed on a surface of the inner covering portion, and a part of the holding groove is provided on the support portion.

The supporting part is made of a material with better strength, so that the clamping groove is deeply embedded into the material of the supporting part, the glass or the plate-shaped material can be fixed in an auxiliary manner by utilizing the self-bonding force of the material of the supporting part with higher strength, and the overall strength of the handrail is further enhanced.

Preferably, in the above-described aspect, the holding groove is a rectangular groove.

The inner contour of the clamping groove is adapted to the edge contour of the glass or plate material.

Preferably, in the above technical solution, the depth of the portion of the clamping groove on the supporting portion is 4 to 7 mm.

Preferably, in the above aspect, the corners of the outer cover and the inner cover are chamfered.

Preferably, in the above technical solution, the support portion is a laminate supported by a plywood.

The support part may be made of a material having a certain strength and toughness, such as solid wood, and plywood is preferred as the material of the support part for cost saving purposes.

Preferably, in the above aspect, the outer cover and the inner cover are both layers made of density plates.

Preferably, the outer cover and the support portion, and the inner cover and the support portion are connected to each other by an adhesive layer.

Preferably, the surface of the handrail is provided with an outer coating.

The outer coating can protect the handrail, prevent the damage that the corruption and striking brought, thereby can also play certain decorative effect through control line and colour.

Preferably, the outer coating is a PVC film.

To sum up, the utility model discloses following beneficial effect has:

the connecting layers among the outer covering part, the supporting part and the inner covering part are not directly acted by external force brought by glass or layered materials to be clamped any more, so that the overall strength of the handrail is improved;

the clamping groove is arranged on the inner covering part of the integrated material, or the clamping groove contains a supporting part of the integrated material, and the glass or the plate-shaped material is fixed by the self-bonding force of the integrated material, so that the overall strength of the handrail is further improved;

the supporting part is made of materials capable of eating nails, and when the objects need to be further reinforced or connected, the handrail provides a precondition foundation for the operation.

Detailed Description

This detailed description is merely illustrative of the present invention and is not intended to be limiting. Any changes that may be made by one skilled in the art after reading the specification of the invention are, within the scope of the claims, protected by the patent laws.

Example 1: referring to fig. 3, the handrail with a clamping function comprises an outer covering part 1 and an inner covering part 2 supported by a middle density board, and a supporting part 3 made of plywood, wherein an outer coating 4 prepared by coating PVC film and glue is arranged outside the handrail, corners of the outer covering part 1 and the inner covering part 2 are chamfered, and the supporting part 3 is arranged between the outer covering part 1 and the inner covering part 2 and bonded by an adhesive layer.

The handrail of this embodiment still include that a cross-section is the centre gripping groove a of rectangle, when centre gripping glass, fix glass through injecting glue to the centre gripping inslot.

The clamping groove a is arranged on the surface of the integrally formed inner covering part 2, and the glass or the plate-shaped material is assisted and fixed through the self-bonding force of the material of the inner covering part 2, so that the overall strength of the handrail is enhanced.

Example 2: the armrest having the gripping function, referring to fig. 4, is different from embodiment 1 in that: the clamping groove a is arranged on the surface of the integrally formed inner covering part 2 and continuously extends into the supporting part 3, the depth of the part, located on the supporting part 3, of the clamping groove a is 4-7 mm, glass or plate-shaped materials are fixed in an auxiliary mode mainly through the self binding force of the materials of the plywood supporting part 3 with higher strength, and the overall strength of the handrail is enhanced.
