Abstract
The invention discloses a train door lock used inner triangular tube, whose section is provided with a special-shaped structure, wherein the outer wall of the train door lock used inner triangular tube is round, and the inner wall of the train door lock used inner triangular tube is triangular. The train door lock used inner triangular tube provided by the invention has the advantages of high intensity, long service life, good abrasive resistance and high precision, can well utilize the special-shaped structure of the inner wall of the tube body to be adaptive to a lock head, so as to achieve the purpose of unlocking.
Description
Technical field
The present invention relates to a kind of steel tubing in different shapes, be specifically related to a kind of train door lock with interior three cornues.
Background technique
Seamless steel tube production is one of national pillar industry, and along with development and national economy, the demand of seamless steel pipe is the trend of cumulative year after year.Seamless steel pipe is used to make structural members such as automobile, train, aircraft, steamer, space gun; And components of machine such as agricultural, mine, engineering, electrician, weaving, military project, seamless steel pipe civil area still be military industry field application all very extensively.Because the circular section steel pipe is stressed more even when bearing inside or outer radial pressure; So obtain a large amount of uses; But in many cases; The circular section steel pipe can not satisfy the specific usage requirement of structure member or mechanical part, therefore just needs extraordinary steel tubes come manufacturing structure parts or mechanical part, improves stock utilization and simplifies purposes such as production technology, shortening manufacture cycle to reach.
Steel tubing in different shapes is compared with pipe, and the sectional shape of pipe is limited, has certain narrow limitation; Can't be used for some specified conditions and environment, and steel tubing in different shapes has more the Economic Section advantage, adapt to the particularity of service condition; Can practice thrift metal; Improve stock utilization, simplify manufacturing process, raise labour productivity; Steel tubing in different shapes is compared with pipe, and steel tubing in different shapes all is superior to pipe in the overall appearance moulding and the design concept of product; Steel tubing in different shapes is compared with pipe, is satisfying under the conditions such as equal usability, and steel tubing in different shapes can alleviate structure weight greatly; The moment of inertia and the section modulus of pipe are less, and under the condition that receives plane bending and distortion, it is big to be not so good as steel tubes resistance to flexure and anti-twist ability; The pipe and the steel tubing in different shapes of the same length of side and diameter, steel tubing in different shapes bearing capacity and shock resistance are better; More than multiple reason limited the service condition and the scope of pipe; Under some particular surroundingss and condition; So adopt steel tubing in different shapes to make structure member or mechanical part, for example: it is good that the train door lock is had an intensity height, long service life, wear resistance with the requirement of pipe, service conditions such as precision height; But also need possess complicated shape and structure, therefore just can not adopt steel tubing in different shapes to make with pipe.
Summary of the invention
A technical problem to be solved by this invention is: provide a kind of intensity height, long service life, wear resistance good, the high train door lock of precision is with interior three cornues.
For solving the problems of the technologies described above; The present invention adopts following technological scheme: a kind of train door lock is with interior three cornues; Said train door lock is abnormally-structured with the cross section of interior three cornues; Said train door lock is with the rounded setting of the outer wall of interior three cornues, and said train door lock is with the setting triangular in shape of the inwall of interior three cornues.
As a kind of optimized technical scheme, said train door lock is the equilateral triangle setting with the inwall of interior three cornues.
As a kind of optimized technical scheme, the center of said inwall and the center of outer wall coincide.
Beneficial effect of the present invention: the train door lock among the present invention is good with interior three cornue intensity height, long service life, wear resistance, and precision is high, can be good at utilizing the abnormally-structured and tapered end of inboard wall of tube body to match, and plays the purpose of unblanking.
Description of drawings
Fig. 1 is the sectional structure schematic representation of train door lock with interior three cornues.
Among Fig. 1: 1, the train door lock is with interior three cornues, and 10, outer wall, 11, inwall.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
See also Fig. 1, a kind of train door lock is with interior three cornues 1, and said train door lock is abnormally-structured with the cross section of interior three cornues, and said train door lock is with the outer wall 10 rounded settings of interior three cornues, and said train door lock is with inwall 11 settings triangular in shape of interior three cornues 1.Said train door lock is the equilateral triangle setting with the inwall 11 of interior three cornues 1.The center of the center of said inwall 11 and outer wall 10 coincides.
Train door lock among the present invention is good with interior three cornue intensity height, long service life, wear resistance, and precision is high, can be good at utilizing the abnormally-structured and tapered end of inboard wall of tube body to match, and plays the purpose of unblanking.
What should explain at last is: the above is merely the preferred embodiments of the present invention; Be not limited to the present invention; Although the present invention has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, and perhaps part technical characteristics wherein is equal to replacement.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (3)
1. a train door lock is characterized in that with interior three cornues: said train door lock is abnormally-structured with the cross section of interior three cornues, and said train door lock is with the rounded setting of the outer wall of interior three cornues, and said train door lock is with the setting triangular in shape of the inwall of interior three cornues.
2. a kind of train door lock as claimed in claim 1 is characterized in that with interior three cornues: said train door lock is the equilateral triangle setting with the inwall of interior three cornues.
