SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a section bar to guarantee carriage frame's anti bending ability.

In order to achieve the above purpose, the utility model discloses a scheme does: the utility model provides a section bar, includes the section bar body, and the middle part of section bar body cross section is two liang of three rectangle frames and meets and the L shape that makes up, and one side of cross section outwards extends two first pterygoid laminas that are parallel to each other along the cross section side is parallel, and the opposite side of cross section outwards extends the second pterygoid lamina along the cross section side is parallel, first pterygoid lamina, second pterygoid lamina and three rectangle frame three integrated into one piece.

The working principle and the beneficial effects of the scheme are as follows: the middle part of the cross section is a structure formed by connecting three rectangular frames in pairs, and the section bar is ensured to have enough bending resistance under the condition of reducing weight to the maximum extent. The L-shaped structure is very suitable for being applied to the corner part of the frame, the corner of the frame is constructed by utilizing the sectional material, the structural strength is high, and the appearance is simple and neat. And the pterygoid lamina of section bar body both sides then can be very fast, firmly be connected with the curb plate structure in carriage, wherein two first pterygoid laminas of parallel extension are convenient for very much to be connected with the curb plate both sides in carriage, and the curb plate joint in carriage can also guarantee installation accuracy and joint strength behind two first pterygoid laminas. And the second wing plate only needs one piece, so that the installation strength can be ensured, and the second wing plate can be conveniently connected with a carriage side plate. The integral molding fully ensures the structural strength.

Optionally, the profile body, the first wing plate or the second wing plate is provided with a U-shaped groove, and the profile further comprises a bayonet lock matched with the U-shaped groove. The bayonet lock is used for fixing on the lateral plate of carriage. The section bar, the first wing plate, the second wing plate and the side plate can be clamped by matching the U-shaped groove and the clamping pin, and the installation is convenient.

Optionally, the cross-section of the bayonet is U-shaped to match the U-shaped channel. The bayonet lock matches with the U-shaped groove completely for area of contact between them is bigger, and the joint is more stable, and life is also longer.

Optionally, the U-shaped groove is formed with a latch bent into an L-shape. The pressure between the clamping pin and the clamping tongue is reduced, the abrasion is reduced, and the service life is prolonged.

Optionally, the lateral end surface of the latch tongue is in a convex arc shape. The processing is more convenient.

Optionally, the transverse end surface of the latch tongue is in the shape of an inward concave arc, and a cylindrical reinforcing rib matched with the inward concave shape is further integrally formed at the bottom of the bayonet lock. The structural strength of the card house and the card pin is enhanced.

Optionally, the lateral end face of the latch is provided with a nylon pad. The clamping tongue is prevented from being in direct contact with the clamping pin, and meanwhile, the clamping pin is prevented from being abraded by the clamping tongue when the vehicle vibrates due to the damping of the nylon cushion.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the section bar comprises a section bar body 1, a U-shaped groove 2, a clamping tongue 3, a transverse end face 4, a clamping pin 5, a reinforcing rib 6, a nylon cushion 7, a first wing plate 8 and a second wing plate 9.

Example one

The embodiment is basically as shown in fig. 1 and fig. 2: the utility model provides a section bar, includes section bar body 1, and the middle part of section bar body 1 cross section is two liang of three rectangle frames and meets and the L shape that makes up, and one side of cross section outwards extends two first pterygoid laminas 8 that are parallel to each other along the cross section side is parallel, and the opposite side of cross section outwards extends second pterygoid lamina 9 along the cross section side is parallel, first pterygoid lamina 8, second pterygoid lamina 9 and three rectangle frame three integrated into one piece. The profile body 1, the first wing plate 8 or the second wing plate 9 are provided with a U-shaped groove 2. A bayonet 5 matched with the U-shaped groove 2 is welded on the side plate of the compartment. The section of the bayonet 5 is in a U shape matched with the U-shaped groove 2. The U-shaped groove 2 is formed with a latch 3 bent into an L shape. The transverse end surface 4 of the clamping tongue 3 is in a convex arc shape.

First pterygoid lamina 8, second pterygoid lamina 9 and section bar body 1 all carry out the joint location through the cooperation of U-shaped groove 2 with bayonet lock 5, and latch 3 offsets with the side of bayonet lock 5, and first pterygoid lamina 8, second pterygoid lamina 9 and section bar body 1 can also be further fixed through modes such as welding, riveting with the fixed of carriage curb plate or other carriage components. The section bar body 1 has enough bending resistance because the three rectangular frames are connected in pairs to form a structure. The whole section is very suitable for being formed on the right-angle side of the carriage frame, and not only has high structural strength, but also is convenient to install.

Example two

The present embodiment is different from the first embodiment in that: as shown in the attached figure 3, the transverse end face 4 of the clamping tongue 3 is in the shape of an inwards concave arc, the bottom of the clamping pin 5 is also integrally formed with a cylindrical reinforcing rib 6 matched with the inwards concave shape, and the transverse end face 4 of the clamping tongue 3 is adhered with a nylon pad 7. The U-shaped groove 2 and the bayonet 5 are connected stably and have a long service life through the concave cross section and the cylindrical reinforcing rib 6, and the nylon cushion 7 absorbs shock to prevent the bayonet 3 from wearing the bayonet 5 when the vehicle vibrates.

The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be pointed out that to those skilled in the art, without departing from the structure of the present invention, a plurality of modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the utility of the present invention.
