1. Field of the Invention
The present invention relates to a simplified rotatable anti-theft tool rack suitable for a tool with a closed head. It utilizes the integral inserting body to insert into the receiving portion of the head of the tool and then directly assemble the tool on the tool rack through a simplified structure, so as to achieve the objectives of safe anti-theft, high safety and quick & easy operation.
2. Description of the Prior Art
The existing tool hanging display structures are various, they have different structures and different functions, and a lot of tool racks or display structures or anti-theft structures designed for the tools with an enclosed head have obtained the patent, for instance:
Wrench Suspension Board disclosed by TW Patent No. 86304252 uses a fastening strap as an anti-theft device, so that the anti-theft effect is rather limited and it is easy to damage the strap from outside, thus improvement is necessary.
A tool rack disclosed by Patent No. 89215602 comprises a rotatable element and a sounding element which are disposed on a rack body. The tool can be positioned on the rack body by cooperating with the rotatable element and the sounding board, the rotatable element is formed with a furcated elastic structure corresponding to the sounding plate or the end of the tool rack, although such a structure has a reverse hook for positioning the tools, the hook can be pulled out or pushed back by force, so that the tools can be taken away and accordingly the anti-theft effect is not good. Furthermore, the integral structure is comparatively complicated; in order to produce sound, between the sounding plate and the tool rack body is arranged a tooth type sound generating device which causes the interspace between the tool rack body and the sounding plate & the tool to be positioned and also causes unnecessary loose of the integral structure.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide a simplified rotatable anti-theft tool rack capable of achieving the anti-theft effect and simplifying the assembly process.
To achieve the abovementioned objectives, the simplified rotatable anti-theft tool rack utilizes the integral inserting body and the relatively simplified tool rack body to safely combine the tool head with the tool rack after the inserting body is engaged with tool head and then has relatively large check force. Thereby, there is not any elastic returning structure to reduce the anti-theft effect of the tool rack, thus achieving the objectives of assuring the anti-theft performance and simplified structure and easy assembly.
The present invention will be more clear from the following description when viewed together with the accompanying drawings, which show, for the purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to
The hanging portion 23 is formed at the center thereof with a limiting portion 231 used to position the inserting body 30. The limiting portion 231 is a through hole with a gap at one side thereof, which is C-shaped or U-shaped. The gap of the limiting portion is a little smaller than the diameter of the through hole and extended outwards to form a straight shape or an outspread trumpet shape. The narrow portion is a stopping portion 232 which is extended outwards to form a slanted open guiding portion 233, at both sides of the guiding portion 233 are formed fastening portions 234 in the form of through holes for insertion of the inserting end 241 of the strap-shaped fixing element 24 into the fixing end 240, so as to tighten and close the stopping portion 232, thus directly restricting the inserting body 30 within the limiting portion 231.
The inserting body 30 includes an engaging portion 31 of a hexagonal or multangular pattern to be inserted through the receiving portion 12 of the tool 10. One end of the engaging portion 31 is provided with a stopping flange 32 for stopping the outer edge of the receiving portion 12 of the tool 10. The other end of the engaging portion 31 is formed with a neck-shaped inserting portion 33 of a round column body or a polygon body, and the outside diameter of the inserting portion 33 is as large as the inside diameter of the limiting portion 231. At the end of the limiting portion 231 which has inserted through the limiting portion 231 is formed a convex big-diameter check portion 34.
During the assembly, when the fixing element 24 has not been inserted into the fastening portion 234, the inserting body 30 can be directly inserted into the receiving portion 12, and through the outspread guiding portion 233, the inserting portion 33 is pushed to slide along the guiding portion 233 and the stopping portion 232 into the limiting portion 231. Afterwards, the fixing element 24 is inserted through the fastening portion 234 to restrict the inserting portion 33 within the stopping portion 232.

Further referring to
The limiting portion 231 disposed on the hanging portion 23 of the tool rack 20 is a structure penetrating the hanging portion 23, that is to say the check portion 34 of the inserting body 30 protrudes out of the rear surface of the hanging portion 23. In addition, the rear surface of the hanging portion 23 of the tool rack 20 can also be in a closed form, as shown in
Further referring to
The abovementioned structure has the following advantages:
1. structure simplification: since the inserting body 30 is integrally formed, the whole of the present invention can be reduced to three components for assembly, thus not only reducing the manufacturing cost, but also reducing the cost and the number of the worker of the assembly.
2. safe anti-theft: the abovementioned structure, especially the fastening portion 234, limiting portion 231, check portion 236 and the like can be disposed in the coverage of check portion 34 of the inserting portion, so as to prevent the destroying or returning operation after the whole assembly, thus achieving the safe anti-theft effect.
3. quick assembly: especially for the structures of the second, third embodiments, the check portion 34 of the inserting body 30 can be directly inserted through the receiving portion 12 of the tool 10, then the inserting portion 33 will go through the guiding portion 233 into the limiting portion 231 and be restricted in the limiting portion 231 without other assembly structures, thus achieving the objective of quick assembly.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
