Description

Retractable cover that simplifies the process

The present invention relates to a mechanical accessory, and more particularly to a telescopic cover that simplifies the process.

In general, mechanical or machine tools, in order to prevent components such as lead screws and linear slides from being contaminated by chips, cutting fluid, dust, etc., most of them will be equipped with a telescopic cover between the moving parts and the fixed parts, such as TW Patent No. M432496, The patent case of M421853 and the like is disclosed.

In the case of TW Patent No. M432496, the folding barrier mechanism includes an upper blocking portion and a front blocking portion, and the ends of the front blocking portion are each bent to produce a flap. In order to bend the flap, the folding barrier mechanism has a complicated process, the manufacturing cost is increased, and the productivity is relatively decreased. Therefore, there is room for improvement for different cost requirements.

In addition, the protective plate of the TW M421853 patent also has a multi-fold shape formed by the connecting portion, the cover portion and the inner curved portion, and also because of the arrangement of the inner curved portion, the process is complicated, the manufacturing cost is high, and the production capacity is high. Also lower.

Therefore, the purpose of the present invention is to provide a simple structure, A low-cost, retractable cover that simplifies the process.

Thus, the present invention simplifies the process of the telescopic cover, comprising a scale unit and a shielding unit. The scale unit has a plurality of scales which are arranged on each other in an axial direction, and each of the scales is integrally formed and sequentially sleeved along the axial direction from small to large, and the scales are inverted L-shaped parallel to the axial cross-sectional shape. Each has a connecting plate and an extending plate that intersects the connecting plate, and each of the extending plates has a fixed end portion connected to the connecting plate and a distal end portion opposite to the fixed end portion, the extending plates The fixed end portion extends to the end portion in a straight shape, and the scales are operated in a condensed state in which the end portions approach each other, and are operated in an extended state in which the end portions are apart from each other, in a condensed state. The connecting plates of the two adjacent scales are also close to each other. In the extended state, the connecting plates of the adjacent two scales are also away, and the end portion of one of the scales is placed at the fixed end of the other scale. Between the end portion and the end portion. The shielding unit is coupled to the scale unit and is made of a flexible cloth material, and has a plurality of fixing portions respectively fixed to the connecting plates and a plurality of shielding portions integrally connected to the fixing portions.

The effect of the present invention is that the scales are inverted L-shaped parallel to the axial cross-sectional shape, and the extension plates extend from the fixed end portion to the end portion in a straight shape, and the scales are simple in structure Easy to manufacture, reducing production costs and increasing production capacity.

Other features and effects of the present invention will be apparent from the following description of the drawings, in which: 1 is a plan sectional view showing an embodiment of the present invention, which can simplify the process of the telescopic cover; FIG. 2 is a partial enlarged view of FIG. 1, illustrating a plurality of scales in an extended state; and FIG. A condensation diagram of one of the above examples illustrates the scales in a condensed state.

Referring to FIG. 1 and FIG. 2, an embodiment of the present invention simplifies the process of the telescopic cover, comprising a scale unit 1, a shielding unit 20 and a locking unit 30.

The scale unit 1 has a plurality of scales 10 which are arranged on each other along an axial direction X. Each of the scales 10 is integrally formed and sleeved in a small to large direction along the axial direction X. The scales 10 are parallel to the axial direction X. The cross-sectional shape is inverted L-shaped, and each has a connecting plate 11 and an extending plate 12 perpendicularly intersecting the connecting plate 11. Each of the extending plates 12 has a fixed end portion 121 connected to the connecting plate 11 and a reverse At the end portion 122 of the fixed end portion 121, the extension plates 12 extend from the fixed end portion 121 to the end portion 122 in a straight shape.

The shielding unit 20 is coupled to the scale unit 1 and is provided with a flexible cloth material, and has a plurality of fixing portions 21 respectively fixed to the connecting plates 11 and a plurality of shielding portions 22 integrally connected to the fixing portions 21, respectively. .

The locking unit 30 can be fixed to the scale unit 1 , and each of the locking units 30 has a clamping plate for clamping the fixing portion 21 of the shielding unit 20 to the connecting plates 11 . 31 and a plurality of rivets 32 that connect the splint 31 to the connecting plate 11.

As shown in FIG. 1 and FIG. 2, after the telescopic cover is integrally assembled, and the telescopic cover is displayed in an extended state, the end portions 122 of the scales 10 are distant from each other and adjacent to each other. The connecting plates 11 of the two scales 10 are also away from each other, and the end portion 122 of one of the scales 10 is disposed between the fixed end portion 121 of the other scale 10 and the end portion 122, and is closer to the fixed end. Part 121.

Further, when the telescopic cover is unfolded, the distal end portion 122 of one of the outer scales 10 is erected between the fixed end portion 121 of the inner scale 10 and the distal end portion 122, so that the phase can be made The occlusion of the adjacent two scales 10 produces a shadowing effect. The shielding unit 20 is subjected to the distance of the scales 10 from each other, and the shielding portions 22 are in an extended state.

As shown in FIG. 3, when the telescopic cover is subjected to an external force such that opposite ends along the axial direction X are pressed inwardly, the scales 10 can be operated by the extended state to make the end portions 122 mutually inclined. In the near condensation state, in the condensed state, the connecting plates 11 of the adjacent two scales are also in a close shape, and the shielding unit 20 is subjected to the approaching of the scales 10, and the shielding portions 22 are pressed. Wavy.

Therefore, the telescopic cover of the present invention has an inverted L shape by perpendicularly intersecting the connecting plate 11 of the scale 10 and the extension plate 12, which is not only simple in structure, but also relatively easy to manufacture, and can reduce manufacturing cost and increase productivity. Achieve the purpose of this new type.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, any simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification are It is still within the scope of this new patent.
