Abstract
The utility model provides a combined-type coupling pin employing a steel structure, which is characterized by the inclusion of an internal pin and an external pin in a matched manner, the external pin is inserted in the internal pin, the internal pin and the external pin adopt the same shape and structure, and one edge is an inclined plane. The angle of the inclined plane of the coupling pin ranges from 60 degrees to 82 degrees. Compared with the connector used in the prior market, the coupling pin provided by the utility model has the following advantages that the installation and the disassembly are convenient, and the transportation and installation cost during the production process can be reduced effectively; the operation is stable and reliable, because the pin is arranged on two contact surfaces, and contacted against the inclined plane, when inserted and connected, the pins are bound with each other, therefore the stability of the structure is improved greatly without the trembling caused by the bad connection; the carrying capacity is high, because the several surfaces of the coupling pins are contacted with each other, the carrying weight is improved greatly, and the service life is improved. After the coupling pin is inserted, because the inclined plane is in contact, the larger the load is, the better the restriction is, the more tight the locking is, and the moresafe and reliable the coupling pin is; and the combined-type coupling pin is suitable for various steel structures such as square pipes, stand pipes, horizontal tubes, elliptical tubes for the bedsiderails and the like.
Description
Technical field
The utility model is a kind of combined type attachment pegs that is used for various steel structure.
Background technique
The most steel structure of existing market all is bolted form, this form is all cumbersome when making and assemble, when particularly assembling, some workpiece volume is bigger, connect with bolt take a lot of work, time-consuming, and expense is higher, the steel structure that part plug tenon head is also arranged on the market, tenon are on the angle of hollow tube, though can assemble fast, reduced cost of transportation and expense, but carrying and stability shortcoming.
Summary of the invention
The purpose of this utility model provides a kind of combined steel structure connecting pin of quick and easy for installation, long service life.
The technical solution of the utility model is: combined steel structure connecting pin is made of sold inside the country and export trade cooperation, and is sold inside the country identical with shape, the structure of export trade in export trade is inserted and is sold inside the country, Yi Bian be the inclined-plane.
The range of bevel angles of attachment pegs is 60 °～82 °.
Attachment pegs of the present utility model has been compared following advantage with the connector that uses in the market:
1. installation, convenient disassembly effectively reduce transportation and installation cost in the production.
2. reliable and stable, owing on two surface of contact, all be by the inclined-plane contact, when inserting connection, constraint has improved stability of structure greatly mutually, can not produce rocking of bad connection.
3. the bearing capacity height because be that several persons of attachment pegs are in contact with one another, has improved load capacity greatly, has improved working life.
4. after this attachment pegs was inserted, owing to be the inclined-plane contact, load was big more, and it is good more to retrain, and locks tightly more, more safe and reliable.
5. this attachment pegs is applicable to various steel structure, as square tube, standpipe, transverse tube, bed shelves elliptical tube etc.
Description of drawings
Fig. 1 is the sold inside the country structural representation of attachment pegs of the present utility model;
Fig. 2 is an attachment pegs export trade structural representation of the present utility model;
Fig. 3 is an attachment pegs scheme of installation of the present utility model;
Fig. 4 is an attachment pegs user mode schematic representation of the present utility model.
Embodiment
As shown in Figure 1, 2, attachment pegs of the present utility model by sold inside the country 1 and export trade 2 cooperate and constitute, export trade insert sold inside the country in, sold inside the country identical with shape, the structure of export trade, Yi Bian be the inclined-plane.This range of bevel angles is 60 °～82 °, is 78 ° among the figure.Be illustrated in figure 3 as sold inside the country and export trade assembling schematic representation.Figure 4 shows that a kind of Placement that is applied on the high sunken bed.
Claims (2)
1, a kind of combined steel structure connecting pin is characterized in that being made of sold inside the country and export trade cooperation, and is sold inside the country identical with shape, the structure of export trade in export trade is inserted and is sold inside the country, Yi Bian be the inclined-plane.
2, combined steel structure connecting pin according to claim 1, the range of bevel angles that it is characterized in that attachment pegs is 60 °～82 °.
