Description

Crawler profile

Technical field

The invention relates to a profile structure, in particular to a track profile. Background technique

As is known to all, the original cabinets and cabinets are mostly in the form of sliding doors, which will occupy a large space when the door is opened. Therefore, some people invented the structure of the sliding door. Although it can solve the problem of occupying space when opening the door, when the sliding door is opened, it can only be opened half. If these cabinets are equipped with electrical equipment such as gas and shower, it is easy. It is inconvenient to cause the operation and maintenance of electrical equipment. In order to solve these problems, some people have further invented the retractable cabinet and cabinet door structure.

For example, the Chinese invention patent specification (authorization bulletin number: CN2546597Y) discloses a wardrobe door which is composed of a take-up tube, a rail and a door body, and the take-up tube is arranged on one side of the closet, and has a center inside. The shaft, the central shaft is provided with a winding reel and a scroll spring, and the winding reel is wound with a drawstring. When the rope is pulled out of the take-up tube, the scroll spring is wound to store the elastic force, and the track is arranged at the side of the wardrobe; The body is in a folded state, which is combined with the drawstring and has its side engaged with the track. When the door body is pulled or the door body is pulled by the drawstring, the door body can be moved along the track, which can be pulled up or down or left and right. It is opened, closed, and has the function of elastic automatic retraction. It is very convenient to open and close, and it is ideal for use. It can guarantee that the door does not take up too much space when it is opened. In addition, when electrical equipment is placed in such a cabinet, since the door body can be completely opened, it does not affect the operation and maintenance of the electrical equipment after the door is opened. The door body described in the above product is composed of a plurality of blade-like bodies and can be folded The louvered structure, of course, can also be made of a flexible cloth.

However, the above products also have the following deficiencies:

1. Although the structure of the door body can be folded, the lining (leaf-like body or flexible cloth) used in it is a material with low mechanical strength, and therefore is not suitable for long-term use.

2. The material used for the door body (blade or elastic cloth) has poor moisture barrier, heat insulation and heat preservation effect, especially the structure of the blade body, which inevitably causes the door body to have a large gap. Therefore, it is not conducive to items stored or placed in the cabinet or cabinet.

3. The door body is a one-piece structure. If an area in the door body is damaged (especially the part that is often folded or slid), it must be replaced as a whole, thus causing an increase in the use cost and waste. Summary of the invention

The object of the invention is to provide a crawler profile, which mainly solves the technical problem that the material of the door body of the existing sliding door structure is not high in mechanical strength and has poor moisture insulation, heat insulation and heat preservation effect, and can be used for cabinets and cabinets. Doors, canopies, roller shutters, bathroom sliding doors, electrical sliding doors, house partition sliding doors and other fields.

To solve the above problems, the present invention is implemented as follows:

A crawler profile characterized in that: it is composed of a connection portion between a first connection end, a second connection end and two connection ends; wherein the first connection end has a C-shaped connection groove in a cross section, and the second connection The end shape is coincident with the c-shaped connecting groove of the first connecting end, and the outer diameter of the second connecting end is larger than the open end of the C-shaped connecting groove. The crawler profile is characterized in that: the arc of the open end of the C-shaped connecting groove has a length of: rr r/2, and r is a radius of the C-shaped connecting groove.

The crawler profile is characterized in that: the distance between a starting end of the open end of the C-shaped connecting groove and the axis connecting line L of the two connecting ends is half of the thickness of the connecting portion.

The crawler profile is characterized in that: the connecting portion is an elongated plate-shaped wall, and the two ends of the wall are respectively connected with connecting ends.

The crawler profile is characterized in that: the second connecting end is a hollow round pipe structure. The crawler profile is characterized in that: the second connecting end is a solid cylindrical structure. The crawler profile is characterized in that: an upper end of the first connecting end extends toward the upper end of the second connecting end and an extending portion, and the upper end surface of the extending portion is a flat surface.

With the above technical solution, the beneficial effects of the present invention are:

1. The profile of the present invention has a certain mechanical strength, and therefore can be used for a long time when used for sliding doors and sliding windows, and has a longer service life than existing products.

2. The sliding door and sliding window composed of the profile of the invention have the effects of heat insulation, moisture insulation, sound insulation and heat preservation.

3. The sliding door and sliding window composed of the profile of the invention can be partially replaced after being worn in a certain part, and no overall replacement is needed, thereby reducing the use cost and avoiding waste. DRAWINGS
