Description

Infinite tandem screw strap for multi-size screws

This writing is about a kind of screw belt; more specifically, it can be used to make the screws of different sizes fully align by the structure of the belt itself, and can be infinitely connected to each unit of the screw belt to fully position the multi-size screw. Infinite tandem screw strap.

According to the development of science and technology, human building technology is also constantly improving. It is also the tool for building use, which is constantly innovating, in order to enable people working on construction sites to work safer and more efficiently; Screw belts have become an indispensable auxiliary tool for the construction industry, especially for those who need to operate at a dangerously high position. With the aid of nailing machines and screw belts, it can be carried out quite conveniently. Screw-locked work to improve work safety and efficiency.

At present, there is a screw belt structure with similar functions on the market. Please refer to FIG. 1 , which is a conventional belt body 1 ′. The conventional belt body 1 ′ is provided with several equidistant adjacent conventional screw inserts. The solid portion 11' and the locking portion 12 that facilitates the series connection with each other are followed by the locking hole 13.

Continuing to refer to FIG. 2, the conventional screw insertion portion 11' includes a through hole 111, and the through hole 111 defines a bearing groove 1111. And an introduction cylinder 112 extends downward to provide an introduction for the insertion of the screw. The introduction cylinder 112 is a hollow conical cylinder having a plurality of slits 113 on the surface. This design enables the polyethylene strip with elastic variables to accommodate screws of different sizes.

At the end of the introduction cylinder 112, it is designed as a positioning ring body 114', and a clamping piece body 1141' is provided at the inner edge of the positioning ring body 114' to assist in guiding the screws.

However, although the above structure can achieve the intended function, the depth of the loading slot 1111 formed in the through hole 111 is insufficient, and the positioning ring body 114' disposed under the introduction cylinder 112 and the screw for securing the screw are provided. The thickness of the clamping piece 1141' is too thin, and the polyethylene material of the belt body is made of a non-rigid material and a crack 113 is opened for implanting screws of different sizes, so that the whole is actually used as shown in FIG. situation.

Referring to FIG. 3, since the above structural strength is insufficient (the loading groove 1111 in FIG. 2 is too shallow and the positioning ring body 114' and the clamping piece body 1141' are too thin), the screw 2 can only be practically operated. With the through hole 111 and the positioning ring body 114' as a fixed fulcrum, an irregular tilting swing is generated on the screw belt after the screw is implanted, resulting in "the screw that can not be screwed, and the screw is stably aligned." The problem of setting the center point of the position causes great inconvenience in operation and use, which affects the efficiency of the screw screw setting, so that there is still room for improvement in the overall structural composition.

Based on this, the creators of this case have been engaged in research and development experience in related fields for many years, and have conducted in-depth discussions on the above-mentioned shortcomings, and actively sought solutions according to the above-mentioned needs. After long-term efforts and multiple tests, creation.

The problem that this creation is to solve is that when using the conventional screw belt, the strength of the screw belt is often insufficient, resulting in an irregular tilting swing on the screw belt after the screw is implanted, resulting in "cannot put the screw on it. Screw, stable alignment to the center of the screwing position."

In order to solve the above problems, the creation system increases the position of the screw body and the positioning groove by modifying the structure of the screw inserting portion, so as to assist the automatic guiding and positioning of the screw, thereby improving the situation that the prior screw arrangement is easily offset and the central axis is irregularly dumped. .

Further, the improved structural effect of the present invention can completely replace the loading groove and the clamping sheet of the existing structure for assisting the clamping of the screw, and the processing steps in the manufacturing process can be greatly reduced.

What's more, because this creation system uses the existing structure with the screw-on-fixed part of the body to make the extension improvement, the overall change is not large at first glance, but it can achieve several times more than the existing structure. .

The main feature of this creation is that the positioning ring body of the conventional screw inserting portion is widened and made into a hollow conical cylinder (improved as a positioning cylinder) like the introduction of the cylinder body. This design can increase the screw after implantation and The contact area of the screw inserting portion makes the screw have more positioning points and can be more completely covered by the covering.

Moreover, the "holding piece for stabilizing the screw" originally disposed in the positioning ring body is replaced by "several positioning grooves" to increase the contact point and friction between the screw screw and the positioning cylinder. Make the screw insert more stable Position the screws so that they do not tilt and swing.

The secondary feature of this creation is that the two ends of the strip are provided with corresponding locking parts and locking holes. The two parts are used for connecting the screw belt and the screw belt in series, so that a large number of continuous locking operations can be obtained. More convenient to complete.

In the structure of the series connection, the two different structural designs are also adopted, which are respectively a general flat belt body, and a "bending portion" is provided to allow the belt body to maintain the same plane after the series connection. Flex the belt body.

The present invention will be further described in conjunction with the drawings and specific embodiments, so that those skilled in the art can more easily understand and implement the present invention.

In order to make the purpose, effect and features of this creation more detailed As far as we can understand, the preferred embodiment is described with reference to the drawings.

First, please refer to FIG. 4, which is a schematic perspective view of the screw belt of the present invention; as in the conventional screw belt, the screw belt of the present invention is still composed of a belt body 1 integrally formed of polyethylene material. The belt body 1 is provided with a plurality of adjacently arranged screw fitting portions 11, a locking portion 12, and a locking hole 13.

The screw insertion portion 11 is composed of a plurality of equally spaced adjacent through holes 111 opened in the belt body 1 and a hollow tapered cylindrical introduction cylinder 112 extending downward from the through holes 111.

The surface of the introduction cylinder 112 is provided with a plurality of mutually symmetric cracks 113. In the design of the crack 113, the creator particularly sets the adjacent two slits 113 to different sizes, so that the screw can be easily worn. The screw insertion portion 11 is released; after the threading, the direction of the rupture of the belt body 1 is also uniform, thereby reducing the occurrence of discontinuities in the nail insertion operation.

The essence of the creation is the design of the positioning cylinder 114 and the positioning groove 1141 presented in the partial enlarged view.

The positioning cylinder 114 is an extension structure of the positioning ring body 114' in FIG. 2. This modification greatly improves the situation in which the positioning ring body 114' is too thin to cause a weak positioning effect; and the number of the inner edge of the positioning cylinder 114 is opened. The strip positioning groove 1141 is used in place of the holding sheet body 1141' mentioned in FIG. 2, and the purpose of the structure is greatly enhanced, so that the screw can be effectively clamped and positioned by the screw fitting portion 11.

Next, please refer to FIG. 5, which is a cross-sectional structural view of the screw fitting portion 11 of the present invention; It is seen that the screw insertion portion 11 extends downwardly from the insertion hole 111 into the cylindrical body 112 and then extends downwardly out of the positioning cylinder 114. The crack 113 is located on the surface of the introduction cylinder 112, and the inside of the positioning cylinder 114 is A plurality of positioning grooves 1141 axially parallel to the screw fitting portion 11 are opened.

When the angle is changed from AA VIEW to the positioning cylinder 114, it can be seen that the positioning groove 1141 is annularly distributed on the inner edge of the positioning cylinder 114. This design can increase the contact between the screw of the screw and the screw fitting portion 11. Points and friction for better grip.

Please refer to FIG. 6 after the screw is implanted. FIG. 6 is a schematic view showing the screw insertion of the screw belt of the present invention; as shown in the figure, after the screw 2 passes through the through hole 111 and the positioning cylinder 114, The axis of the screw 2 can be sufficiently fixed to the axial position of the through hole 111 and the positioning cylinder 114, so that the screw 2 is no longer tilted and tilted as the screw 2 in FIG. 3, and the improvement can also make the screw belt The use is more convenient for the construction personnel to enter the nailing operation, thereby improving the efficiency of the nailing operation.

Please refer to Figure 7 to Figure 10, and Figure 7 to Figure 10 are schematic diagrams of the application of the creation on the infinite series. The 7th and 8th drawings are the general flat belts in the creation. FIG. 9 and FIG. 10 are a perspective view and a tandem front view of the flex strip body of the present invention.

From Fig. 7 and Fig. 8, we can see that the locking portion 12 at both ends of the screw belt and the locking hole 13 can be correspondingly locked. Here, it is particularly pointed out that the conventional screw belt has already been The setting of the locking parts; only some screws have only adopted a single-hole locking design, although this design is The cost is saved, but it is easy to get stuck in the alternate position of the screw when the screw gun is brought in.

Therefore, the screw belt described in the present invention adopts more than two locking component designs. Such a setting can make the connected screw belts be straight and connected in series, which is beneficial to the nailing operation.

However, as shown in FIG. 8 , when the screw belt of the general flat belt body is fastened, the two adjacent screw belts may have a plane inconsistency, as shown in the figure, two screw belts connected to each other, the positioning cylinder The position of the bottom of the body 114 is not at the same level.

Therefore, the creator also creates a screw belt with a folded belt body. As shown in FIGS. 9 and 10, the belt body 1 is provided with a bent portion 14 at the end of the locking portion 12, and the bent portion 14 is provided. The belt body 1 is caused to have a plane difference of the thickness of the belt body 1, so that when the locking portion 12 is locked with the locking hole 13, the height of the screw belts connected in series can be maintained in the same plane.

It can be seen that this creation has excellent progress and practicability in similar products. At the same time, after checking the technical information lines of such structures at home and abroad, it is true that no identical or similar structure exists before the application of this case. Therefore, the case should be submitted in accordance with the law in accordance with the patent requirements of "creative", "combined with industrial use" and "progressive".
