BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a film packing device for a roll of film which does not have a reel therein.

2. Description of the Prior Art

In order to avoid an article from falling during transportation, a roll of film is used to pack the article for providing a secure effect. In general, a film reel made of paper is provided in the roll of film. The user uses a film packing device to connect with two sides of the roll of film for packing. To consider the environmental protection, the roll of film is designed to be one without a reel. There is no support for the roll of film. The conventional film packing device can not fix the two ends of the roll of film securely, casing a little trouble to the user. This is unfavorable for packing. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve this problem.

SUMMARY OF THE INVENTION

The present invention is to provide a film packing device comprising a handle. The handle has a first connection rod and a second connection rod at two lateral ends thereof. A film packing unit and a roller unit are provided between the first connection rod and the second connection rod. The film packing unit comprises an axle tube, a first rolling member and a second rolling member. The axle tube has a first positioning portion and a second positioning portion at two ends thereof. One end of the first rolling member has a first connecting portion corresponding to the first positioning portion of the axle tube to connect with the axle tube. The other end of the first rolling member is connected with a quick-release member. The first rolling member is pivotally connected to the first connection rod through the quick-release member. One end of the second rolling member has a second connecting portion corresponding to the second positioning portion of the axle tube to connect with the axle tube. The other end of the second rolling member is connected with a pivot member. The second rolling member is pivotally connected to the second connection rod through the pivot member. A roll of film is fitted on the axle tube with the axle tube to provide a support effect for the user to pack an object in a quick, simply and convenient way.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown inFIGS. 1 to 3, a film packing device100according to a preferred embodiment of the present invention comprises a handle10and a film packing unit20.

The handle10has a first connection rod11and a second connection rod12at two lateral ends thereof. The first connection rod11has a first positioning hole111and a first fixing hole112thereon. The second connection rod12has a second positioning hole121corresponding in position to the first positioning hole111and a second fixing hole122corresponding in positioning to the first fixing hole112.

The film packing unit20is disposed between the first connection rod11and the second connection rod12. The film packing unit20comprises an axle tube21, a first rolling member22, a quick-release member23, a second rolling member24, and a pivot member25.

The axle tube21can be formed in one-piece or composed of a plurality of sleeves211which are connected one by one, as shown inFIG. 3. Each sleeve211has a first positioning portion211at one end thereof and a second positioning portion213at an opposing end thereof. With the first positioning portion212and the second positioning portion213, the sleeves211are connected together to form the axle tube21. Two ends of the axle tube21are formed with the first positioning portion212and the second positioning portion213, respectively. In this embodiment, the first positioning portion212is a protruding ring. The first positioning portion212has a positioning block214on an outer surface thereof. The second positioning portion213is a trough. The second positioning portion213has a limit groove215on an inner wall thereof to connect with the first positioning portion212. Each sleeve211further includes three tightening pieces216thereon, so that the axle tube21has a number of tightening pieces216thereon.

Referring toFIG. 4, one end of the first rolling member22has a first connecting portion221corresponding to the first positioning portion212of the axle tube21. The first connecting portion221is a trough. The first connecting portion221has a positioning groove222thereon to connect with the first positioning portion212of the axle tube21. The other end of the first rolling member22has a protruding ring223corresponding to the first positioning hole111of the handle10. The protruding ring223has two slots224thereon. The quick-release member23is disposed in the protruding ring223. The quick-release member23includes a fixing rod231and a spring232which is located between a bottom of the protruding ring223and the fixing rod231. One end of the fixing rod231, opposite to the spring232, is extended out the protruding ring223by the spring232and inserted in the first positioning hole111, such that the first rolling member22is pivotally connected to the first connection rod11. The fixing rod231has two limit levers233at two sides thereof corresponding to the two slots224for the user to apply force.

Referring toFIG. 5, one end of the second rolling member24has a second connecting portion241corresponding to the second positioning portion213of the axle tube21. The second connecting portion241is a protruding ring. The second connecting portion241has a limit block242thereon to connect with the second positioning portion213of the axle tube21. The other end of the second rolling member24has a circular trough243to connect with the pivot member25. The pivot member25includes a pivot block251received in the circular trough243. The pivot block251is rotatable in the circular trough243. The pivot block251has a threaded hole252for insertion of a pivot rod253. One end of the pivot rod253, opposite to the pivot block251, is provided with a stop block254and inserted in the second positioning hole121, such that the second rolling member24is pivotally connected to the second connection rod12.

In addition, the film packing device100further comprises a roller unit30which is disposed between the first connection rod11and the second connection rod12. The roller unit30has two rollers31. Two ends of each of the rollers31are provided with gears32to mesh with each other, so that the rollers31are driven to rotate. An outer side of the gears32is provided with a casing33. One end of the casing33is provided with a connection shaft34to be inserted in the first fixing hole112of the first connection rod11and the second fixing hole122of the second connection rod12, respectively. The casing33close to the second rolling member24has one side formed with an extension portion331. The extension portion331has a guide groove332thereon. The guide groove332is connected between the pivot block251and the stop block254of the pivot member25to confine the turning of the roller unit30.

FIG. 6andFIG. 7are schematic views showing the present invention when in use. When the user wants to use the film packing device100, a roll of film200which does not have a reel therein is mounted in the film packing device100. As shown inFIG. 4, the user pulls the limit levers233of the quick-release member23to pull up the fixing rod231towards the axle tube21, so that the fixing rod231disengages from the first positioning hole111of the first connection rod11. The film packing unit20is taken out from the handle10, and then the first rolling member22is disengaged from the axle tube21. As shown inFIG. 7, the roll of film200is fitted on the axle tube21with the fastening pieces216to prop the roll of film200, achieving a support effect. The first rolling member22is then connected to the axle tube21. As shown inFIG. 5, the pivot block251of the pivot member25is inserted in the circular trough243of the second rolling member24. As shown inFIG. 4, the fixing rod231of the quick-release member23is secured in the first positioning hole111of the first connection rod11, such that the roller of film200is mounted on the film packing device100. As shown inFIG. 7, the user uses the film packing device100of the present invention to pack an object300in a quick, simple and convenient way.
