Abstract
The utility model discloses a kind of clamping structures of track, sheet metal including bracket and at left and right sides of carriage length direction, the back side of bracket is equipped with groove at head and the tail both ends, two sheet metals are equipped with punching hole at head and the tail both ends, each punching hole forms protrusion in the other side of sheet metal, and the spacing between the punching hole at sheet metal head and the tail both ends is equal to the spacing between the groove at bracket head and the tail both ends.The protrusion of head and the tail is clamped in respectively in the groove at head and the tail both ends;The design reduces the back sides of procedure of processing, and track to seem very smooth, and protrusion, which is located inside sheet metal, will not generate sharp edge, will not hurt hand naturally.This utility model is used for goods shelf equipment field.
Description
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.
