Abstract

The utility model relates to a railing, which comprises transversal pipes and vertical pipes, wherein the transversal pipes comprise surface pipes at the top and flat pipes at the bottom; the bottom of the surface pipes is provided with punch holes; the top ends of the vertical pipes extend into the punch holes for installation; and the vertical pipes and the edges of the punch holes are fixedly welded at the joint. The utility model has the advantages of reasonable structure, simple product process and reliable quality. Because the top ends of the vertical pipes extend into the punch holes for installation, the products do not have the conditions such as failure, desquamation and the like when in use.

Description

A kind of railing

Technical field

The utility model relates to a kind of railing.

Background technology

The main body of common metal railing generally is made of the transverse tube and the vertical tube of hollow, the transverse tube at railing top is the bigger facial canal of body, mainly be to use as handrail, when making, be connected in the bottom surface of facial canal, when welding, can adopt spot welding maybe will connect the mode of welding entirely with the upper end welding of vertical tube or with bolt.But no matter be that spot welding connects or full solid welding is decided, all there is weak point: at first, as the vertical tube end points being welded in the bottom surface of facial canal, its structure is firm inadequately, situation about coming off appears in use easily, and because dock with the facial canal bottom surface upper end of vertical tube, this position the slit can occur unavoidably, thereby influences the attractive in appearance of railing; If the complete weld all around of the interface between vertical tube and the facial canal is got up, though it is firm like this, but cause tubing welding deformation to occur in welding process easily, influence next step processing or influence the overall appearance of railing, to add man-hour in polishing also inconvenient for this soldering opening simultaneously.And when adopting bolt to connect, then have complex process, the shortcoming of trouble is installed.

The utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of reliable in quality, stressed railing reasonable, that process easily.

The technical scheme that the utility model adopted is:

A kind of railing, this railing comprises transverse tube, vertical tube, and described transverse tube comprises the facial canal at top and the flat tube of bottom, and the bottom of described facial canal is provided with punching, and the top of described vertical tube is stretched in the punching and is installed, and the contact position spot welding at vertical tube and punching edge is fixed.

The beneficial effects of the utility model are: the bottom of facial canal is provided with punching, when producing, the top of vertical tube stretched in the punching and install, fix in the contact position spot welding at vertical tube and punching edge again, this product rational in infrastructure, production technology is simple, and reliable in quality is installed because the top of vertical tube is stretched in the punching, therefore product is when making, and situation such as can not occur rupturing, come off.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that partial sectional view is amplified at the A position of Fig. 1;

Fig. 3 is the STRUCTURE DECOMPOSITION figure of facial canal and vertical tube;

Fig. 4 is the square-section schematic diagram of facial canal;

Fig. 5 is the another kind of cross sectional shape schematic diagram of facial canal.

The specific embodiment

Referring to figs. 1 through Fig. 5, a kind of railing, this railing comprises transverse tube, vertical tube 1, described transverse tube comprises the facial canal 2 at top and the flat tube 3 of bottom, the bottom of facial canal 2 is provided with punching 21, this adaptation of cross sectional shape of the shape of punching and vertical tube, when producing, the top of vertical tube 1 is stretched in the punching 21, carry out spot welding at vertical tube 1 with the contact position at punching 21 edges again and fix, the technology of this product is simple, and is all more convenient when location and assembling, technical requirements to operating personnel is not high, product is fit to produce in batches, and the sound construction of product, reliable in quality, durable.

As required, the shape of described facial canal 2 can be multiple, and as shown in Figure 4, the cross sectional shape of described facial canal is a rectangle, in addition, also can be as the accompanying drawing 5 described special pipes of projection up, or the cross section of other shape.

The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection domain, so long as realize that with essentially identical means the purpose of this utility model all should belong to protection domain of the present utility model.

Claims (3)

1. railing, this railing comprises transverse tube, vertical tube (1), described transverse tube comprises the facial canal (2) at top and the flat tube (3) of bottom, it is characterized in that: the bottom of described facial canal (2) is provided with punching (21), the top of described vertical tube (1) is stretched in the punching (21) and is installed, and vertical tube (1) is fixed with the contact position spot welding at punching (21) edge.

2. a kind of railing according to claim 1 is characterized in that: the cross section of described facial canal (2) is a rectangular shape.

3. a kind of railing according to claim 1 is characterized in that: described facial canal (2) is the cross section top special pipe of projection up.
