In order to further understand the functions, technical means, and expected effects of the cooperation of the various components of the present invention, it is to be noted that the following is a more in-depth and specific understanding of the present invention.

Referring to FIG. 4, before the telescopic shield with the embedded restraint band of the present invention is to be combined, the body 31 of the restraining strip 30 and the connecting member 32 are previously integrated by a high-frequency connection, and the shielding unit 20 is fixed. The portion 21 is also connected to the side edge 11 of each of the support plates 10 by high frequency in advance, and the fixed portions 21 and the side edges 11 of each of the support plates 10 are subjected to high-frequency welding.

Next, when the present type of telescopic shield with embedded restraint straps is to be combined, as shown in FIG. 5, the operator first operates the extensions 322 in an original state (see FIGS. 3 and 4) into a curl. a deformed state, and the flaps 324 in the state of the curled state are wound relative to the intermediate section 323, the wings 324 are overlapped with each other, and the width of the curled deformed portions 322 along the transverse axis Y is changed. Small, and the curled deformed portions 322 can pass through the corresponding slots 213 of the shielding unit 20, and when the curled deformed portions 322 pass through the slots 213, the extensions The 322 is disposed between the support plates 10 and the shielding portions 22, and the side flaps 324 of the extending portions 322 are unfolded relative to the intermediate portion 323 by the material properties of the extending portions 322. The extensions 322 are restored to the original state (see FIGS. 3 and 4), and the shoulder portions 325 are used to lock the fixing portions 21 on both sides of the slots 213, and the wings 324 are utilized. Positioning is generated with respect to the shielding unit 20, so that the limiting band 30 as a whole and the shielding Unit 20 produces a connection and assembly is complete.

As shown in FIG. 3 and FIG. 6 , the shielding unit 20 and the limiting band 30 are displayed in an extended state. At this time, the supporting members 10 are away from each other, the fixing portions 21 of the shielding unit 20, and the connections are The member 32 is also in a state of being distant, and the body 31 is unfolded into a flat shape. When the support members 10 are externally applied and close to each other (not shown), the shielding unit 20 and the body 31 of the restriction band 30 are in a condensed state (not shown).

Therefore, the present invention utilizes the arrangement of the restriction band 30 to avoid excessive expansion of the telescopic shield and to extend the service life of the telescopic shield. And the connecting member 32 is pre-connected to the main body 31. The support plate 10 is also integrated with the shielding unit 20 in advance, and the connecting members 32 that operate the restraining strip 30 are operated from the original state into a curled state. The connecting members 32 can be positioned in the shielding unit 20 in an embedded manner, and the extending portions 322 can be positioned relative to the shielding portions 22 without using an adhesive manner, and the overall structure is simple and the manufacturing is assembled. It is also quite easy.

In addition, the efficacy of the new type of telescopic shield with embedded restraint band is summarized as follows:

1. The extensions 322 of the restraining strips 30 can be operated in a curled state from the original state, and the stretched portions 322 of the warp-deformed state can be easily passed through the corresponding slots 213 of the shielding unit 20, and such The extension portion 322 is positioned relative to the shielding unit 20, so that the connection between the restriction band 30 and the shielding unit 20 does not need to pass through the adhesive or apply a high-frequency operation to generate a connection, which can save the process and reduce the cost.

2. The connecting strip 30 and the shielding unit 20 can be connected without passing through the adhesive. Even if the oil or water is affected, the connecting member 32 of the limiting strip 30 does not easily fall off from the shielding unit 20. Extends the life of the bellows.

3. The ratio of the first width w1 to the second width w2 is 0.5, and the second width w2 of the extensions 32 and the shielding portion 22 of the shielding unit 20 correspond to the total width w of the transverse axis Y. If the ratio is 0.4, the width of the slots 213 corresponding to the transverse axis Y need not be too large, and the structural strength of the shield unit 20 as a whole is not damaged.

In summary, the present invention has a telescopic shield with an embedded restraint belt, the overall structure is simple, the manufacturing assembly is easy, and the service life of the telescopic shield can be extended, and the purpose of the novel can be achieved.

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, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
