Description

Miniature directional pulley in pull frame bottom

Technical Field

The utility model relates to a pull frame technical field specifically is a miniature directional pulley in pull frame bottom.

Background

Contain the base on the pull frame and on the base gliding drawer, can slide relative base when current drawer pull, owing to adopt the slip mode of face and face contact, so make the drawer pull unsmooth, overall speaking just two product direct friction carry out the pull and put and get article, the slip effect is poor, the abnormal sound appears in the pull, influences product life and product use and experiences.

Therefore, the utility model provides a miniature directional pulley in pull frame bottom.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a miniature directional pulley in pull frame bottom to solve the problem that proposes in the above-mentioned background art, the utility model discloses a set up sliding assembly between base on the pull frame and the drawer and reduce contact friction power, make the pull smooth and easy noiselessness more.

In order to achieve the above purpose, the present invention is realized by the following technical solution: a miniature directional pulley at the bottom of a drawing frame comprises a sliding component positioned between a base and a drawer, wherein the base is in sliding fit with the drawer through the sliding component.

Furthermore, the sliding assembly is provided with a roller and a roller shaft positioned in the middle of the roller, and the base is in contact with the drawer through the roller.

Furthermore, the peripheral wall of running roller and drawer lower extreme face just are close to the position contact of avris.

Furthermore, running roller and roller fixed connection, just for rotating the connection in the roller embedding base.

Furthermore, the roller is the one end setting that is close to the base.

Furthermore, the periphery wall of the roller wheel is provided with a notch positioned at one end.

The utility model has the advantages that: the utility model relates to a miniature directional pulley at the bottom of a drawing frame, which comprises a base; a drawer; a sliding assembly; a roller; a notch; and (4) a roll shaft.

1. Set up the sliding component between base and drawer, the last setting of sliding component is located base up end and drawer under the running roller between the terminal surface, running roller and base rotate to be connected, when the pull drawer, can reduce the contact friction between drawer and the base under the effect of running roller, and then make the pull smooth and easy.

2. The sliding assembly is provided with a roller shaft fixedly connected with the roller wheel, the roller shaft is embedded into the base and is rotatably connected with the base, and therefore the size of the drawing frame can be greatly reduced, and the manufacturing difficulty is reduced.

3. The breach that is close to one end is seted up to the periphery wall of running roller, and this breach can avoid the drawer to appear skidding when with the running roller contact motion.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1 to 5, the present invention provides a technical solution: the utility model provides a miniature directional pulley in pull frame bottom, including the sliding component 3 that is located between base 1 and the drawer 2, base 1 passes through sliding component 3 and 2 sliding fit of drawer, it is specific to be provided with running roller 31 on the sliding component 3 and be located the roller 32 at running roller 31 middle part, base 1 passes through running roller 31 and the contact of drawer 2, during manual pull drawer 2, running roller 31 rolls and reduces the frictional force between drawer 2 and the base 1, wherein the position contact of terminal surface and the avris under running roller 31's the periphery wall and the drawer 2, that is to say running roller 31 sets up the stub roll structure into, its distributes and is close to the position of both sides on base 1, in this embodiment, the quantity of running roller 31 between base 1 and the drawer 2 is two.

This embodiment, running roller 31 and roller 32 fixed connection, that is to say that both are the structure of formula of one-piece, roller 32 imbeds in the base 1 and connects for rotating, it is concrete to set up the U type recess that matches with running roller 31 and roller 32 at base 1's up end, roller 32 and U type recess adopt clearance fit's mode to realize rotating the connection, can reduce the volume that the pull frame occupy from this, wherein the breach 311 that is located one end is seted up to running roller 31's periphery wall, this breach 311 can increase the frictional force of running roller 31 periphery wall and the contact of drawer 2, avoid roller 32 to appear the nonrotative phenomenon of jamming.

This embodiment, roller 32 are the one end setting of being close to base 1, and specific saying so is exactly after the drawer 2 outwards stimulates certain stroke, and running roller 31 still contacts with the lower terminal surface of drawer 2, and smooth and easy pull drawer 2 is not influenced in this kind of setting, reduces the degree of difficulty of pull frame preparation.

When the drawing frame is used, the drawer 2 is manually drawn, the roller 31 rolls under the action of friction force, the roller shaft 32 rotates on the base 1, and then the drawer 2 is smoothly drawn.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
