Description

A kind of self weight sliding rail that frictional force is small

Technical field

The utility model relates to goods shelf equipment fields, more particularly to a kind of self weight sliding rail that frictional force is small.

Background technique

Self weight sliding rail in refrigerator-freezer available on the market have it is horizontal, also have it is inclined, all have hold bottled cargo Function.It is self-possessed on sliding rail with multiple roller bearings and carries multiple rolling shaft supports, each roller bearing is thin ends and thick middle ladder Axis, the groove being caught at two minor diameters of each roller bearing at left and right sides of bracket, and arrangement is opened radially, the major diameter of roller bearing Place's protuberance avoids the bottom of bottled cargo from touching bracket in bracket, and final effect is that bottled cargo can be moved up in roller bearing It is dynamic, and each roller bearing only needs rotation.

Discovery has bottled commodity card among self weight sliding rail once in a while in use, and tracing it to its cause is that roller bearing rotation has some setbacks The bottom of (the small multi-diameter shaft at the head and the tail both ends of roller bearing and the contact surface of bracket are too big), bottled cargo has touched self weight sliding rail (some bottled cargos are flat moulding, and injection hole sometimes can protrude from bottom of bottle because of mismachining tolerance), acts in two factors The critical value that lower frictional force just reaches.In order to reduce roller bearing and be self-possessed sliding rail between friction, in order to reduce bottled cargo with The friction of self weight sliding rail, existing self weight sliding rail still have improved space.

Utility model content

The purpose of this utility model is to provide a kind of self weight sliding rails that frictional force is small.

Technical solution adopted in the utility model is:

A kind of self weight sliding rail that frictional force is small, including the bracket for bearing roller bearing, the front of bracket is set along its length There are several slot positions, self-assembling formation partition between adjacent two slot position, each partition is equipped with notch in middle position, each slot position Head and the tail both ends are equipped with the deep gouge of storage roller bearing, and each deep gouge opening upwards, the bottom of each deep gouge sets bossed step.

As an improvement of the above scheme, each notch is the cambered surface to lower recess.

As an improvement of the above scheme, each step is the cambered surface swelled upwards.

As an improvement of the above scheme, after being put into roller bearing in slot position, the top edge of bracket lower than roller bearing top edge 3~ 5mm。

As an improvement of the above scheme, bracket includes positioned at the head and tail portion at head and the tail both ends, the top surface on head and tail portion It is equipped with card slot along the width direction of bracket with bottom surface, each clamp bar slot runs through bracket, and each clamp bar slot is equipped in the position of inlet and outlet Angle or rounding.

As an improvement of the above scheme, the top edge of each partition is equipped with cylindrical card column in the left and right sides of notch, The spacing of card column on adjacent two partition is less than the spacing of adjacent two partition.

As an improvement of the above scheme, the bottom hollow processing of each slot position.

The utility model has the beneficial effects that the centre of this self weight sliding rail has notch, it can be to avoid the bottled cargo in part Injection hole touches bracket, avoids stuck；And the effect of step is to reduce the contact area of roller bearing and bracket, reduces frictional force, A roller bearing line approximate in the theory of interface of bracket at this time；Above-mentioned two improvement combines, so that bottled cargo Movement is very smooth.

Detailed description of the invention

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

Fig. 1 is the overall schematic of bracket；

Fig. 2 is the enlarged drawing on bracket head；

Fig. 3 is the enlarged drawing of deep gouge position；

Fig. 4 is the cross-sectional view of deep gouge position.

Specific embodiment

Referring to figs. 1 to Fig. 4, the utility model is a kind of self weight sliding rail that frictional force is small, and self weight track passes through injection molding Processing, including the bracket 1 for bearing roller bearing 6, the front of bracket 1 is equipped with several slot positions along its length, and several are rolled Axis 6 is placed in slot position.Some structures of self weight sliding rail belong to the prior art, and which is not described herein again.

Here is improvement, self-assembling formation partition 2 between adjacent two slot position, and each partition 2 is equipped with notch in middle position 7, the head and the tail both ends of each slot position are equipped with the deep gouge 3 of storage roller bearing 6, and each 3 opening upwards of deep gouge, the bottom of each deep gouge 3 is set Bossed step 4.Each notch 7 is the cambered surface to lower recess；Each step 4 is the cambered surface swelled upwards.

Step 4 in the present embodiment is cambered surface, the step 4 of rectangle different from the past, since 4 position of step is less than normal, i.e., The higher precision that mold is needed in injection molding；And the advantages of step 4 of cambered surface compared to the step 4 of rectangle, reduce the rib of mold Angle, mold are more easier to manufacture and correct.

Notch 7 can touch bracket 1 to avoid the injection hole of the bottled cargo in part, avoid stuck；And the effect of step 4 is The contact area of roller bearing 6 and bracket 1 is reduced, reduces frictional force, roller bearing 6 is one approximate in the theory of interface of bracket 1 at this time Line；Above-mentioned two improvement combines, so that the movement of bottled cargo is very smooth.

As preferred embodiment, after being put into roller bearing 6 in slot position, the top edge of bracket 1 is lower than the top edge of roller bearing 6 3~5mm.When the design is that the bottled cargo bottom of reply is bigger than normal, the bottom margin of bottled cargo is likely to be exposed lacking for bracket 1 Point.Also for frictional force is reduced, so that the movement of bottled cargo is smooth.This improvement and both the above improvement group close Come, self weight sliding rail in addition to have the function of it is initial other than, the bottled cargo of various complexity can be coped with, with very strong versatility.

As preferred embodiment, bracket 1 includes positioned at the head and tail portion at head and the tail both ends, the top surface on head and tail portion It is equipped with card slot along the width direction of bracket 1 with bottom surface, each clamp bar slot runs through bracket 1, and each clamp bar slot is equipped in the position of inlet and outlet Chamfering or rounding.

The top edge of each partition 2 is equipped with cylindrical card column 5, the card on adjacent two partition 2 in the left and right sides of notch 7 The spacing that the spacing of column 5 is less than adjacent two partition 2 is used to hospitalize roller bearing 6 in this way.Roller bearing 6, can be first during being put into slot position Two adjacent partitions 2 are strutted, are then inserted into.The bottom hollow processing of each slot position mitigates the weight of bracket 1.

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.
