Description

A kind of clamping structure of track

Technical field

The utility model relates to goods shelf equipment fields, more particularly to a kind of clamping structure of track.

Background technique

Holder in refrigerator-freezer available on the market has horizontal, also has inclined, all has and hold the function of bottled cargo Energy.There are multiple roller bearings on Holder and carry multiple rolling shaft supports, each roller bearing is thin ends and thick middle multi-diameter shaft, often The groove being caught at two minor diameters of a roller bearing at left and right sides of bracket, and arrangement is opened radially, it is grand at the major diameter of roller bearing Arising from bracket avoids the bottom of bottled cargo from touching bracket, and final effect is that bottled cargo can move on roller bearing, and Each roller bearing only needs rotation.

Holder is assembled side by side by several tracks, to note here is that the structure of track itself.Traditional rail Road needs the preboring screw hole on plastic part in an assembling process, is then connected when aluminium alloy sheet body coating plastic part by screw It connects, although this method makes track have stronger stability, but process flow is more.It is found in practice, track Intensity still be able to after reduction using.

Utility model content

The purpose of this utility model is to provide a kind of clamping structures of the processing is simple track easy to use.

Technical solution adopted in the utility model is:

A kind of clamping structure of track, the sheet metal including bracket and at left and right sides of carriage length direction, bracket The back side is equipped with groove at head and the tail both ends, and two sheet metals are equipped with punching hole at head and the tail both ends, and each punching hole is in sheet metal The other side form protrusion, the spacing between the punching hole at sheet metal head and the tail both ends be equal to bracket head and the tail both ends groove between Spacing.

As an improvement of the above scheme, the outer ledge of groove is equipped with chamfering or rounded corner, and the protrusion that punching hole is formed is Prismatic table shape or truncated cone-shaped.

As an improvement of the above scheme, bracket uses plastic material, passes through injection molding.

As an improvement of the above scheme, sheet metal is aluminium flake, and the section of sheet metal in the longitudinal direction is U-shaped, every one side Sheet metal encase the one of edge side of bracket.

As an improvement of the above scheme, the head and the tail both ends of bracket are respectively equipped with a frame and tailstock, and head frame and tailstock are aluminium The section of piece, head frame and tailstock be U-shaped and can clamping carrier, bracket is all provided with grooved hole at head and the tail both ends, and head frame and tailstock are all provided with There is punching hole, punching hole forms protrusion in the inside of head frame or tailstock and is embedded in slot.

The utility model has the beneficial effects that this clamping structure guarantees the connection of sheet metal and bracket using pairs of protrusion, The protrusion of specifically head and the tail is clamped in respectively in the groove at head and the tail both ends；The design reduces procedure of processing, and the back of track Face seems very smooth, and protrusion, which is located inside sheet metal, will not generate sharp edge, will not hurt hand naturally.

Detailed description of the invention

The utility model is described in further detail with reference to the accompanying drawing:

Fig. 1 is the partial schematic diagram of clamping structure；

Fig. 2 is the schematic diagram of entire track.

Specific embodiment

Referring to Figures 1 and 2, the utility model is that a kind of clamping structure of track is cut in Fig. 1 since track is too long Intermediate duplicate part.Bracket includes separable head, body and tail, and three's sequential concatenation forms；Face is equipped with several rollings with it The track in left side is the schematic diagram for eliminating body in axis, Fig. 1 and Fig. 2.Clamping structure include bracket and be located at carriage length side The back side of the sheet metal 1 of two sides to the left and right, bracket is equipped with groove 2 at head and the tail both ends, and groove 2 prolongs along the width direction of bracket It stretches.Further, it is processed using Sheet Metal Forming Technology, two sheet metals 1 are equipped with punching hole 3 at head and the tail both ends, and each punching hole 3 is in gold The other side for belonging to piece 1 forms protrusion, and the spacing between the punching hole 3 at 1 head and the tail both ends of sheet metal is equal to the ditch at bracket head and the tail both ends Spacing between slot 2.By taking Fig. 1 as an example, the distance between the right and the left side of groove 2 of tail portion of the groove 2 on head are equal to head The distance between the left side of the protrusion on the right and tail portion of the protrusion in portion；It of courses, " being equal to " said herein allows to have processing to miss Difference.

In the present embodiment, bracket uses plastic material, passes through injection molding.Sheet metal 1 is aluminium flake, and sheet metal 1 is in length Section on direction is U-shaped, and the sheet metal 1 on every one side encases the one of edge side of bracket.The head and the tail two of each sheet metal 1 A protrusion is respectively set in end.

As preferred embodiment, the outer ledge of groove 2 is equipped with chamfering or rounded corner, the protrusion that punching hole 3 is formed For prismatic table shape or truncated cone-shaped.Inclined-plane and inclined-plane cooperation are more easier to position and compress, and offset mismachining tolerance.

This clamping structure guarantees the connection of sheet metal 1 and bracket, the specifically protrusion of head and the tail using pairs of protrusion respectively It is clamped in the groove 2 at head and the tail both ends；The design reduces the back sides of procedure of processing, and track to seem very smooth, protrusion Sharp edge will not be generated inside sheet metal 1, will not hurt hand naturally.

As preferred embodiment, the head and the tail both ends of bracket are respectively equipped with a frame 4 and tailstock 5, and head frame 4 and tailstock 5 are equal For aluminium flake, the section of head frame 4 and tailstock 5 be U-shaped and can clamping carrier, bracket is all provided with grooved hole, head frame 4 and tail at head and the tail both ends Frame 5 is equipped with punching hole 3, and punching hole 3 forms protrusion in the inside of head frame 4 or tailstock 5 and is embedded in slot.The design principle and upper Face it is identical, be all to try to increase the track back side flatness.At the same time, sheet metal 1, head frame 4 and tailstock 5 track just Face does not need setting punching hole 3.

Certainly, the design creation is not limited to above embodiment, and the combination of the various embodiments described above different characteristic can also To reach good effect.Those skilled in the art can also make without departing from the spirit of the present invention It is all included in the scope defined by the claims of the present application with deformation or replacement, these equivalent variation or replacement.
