Abstract
The invention discloses a special wrench for a PVC (polyvinyl chloride) foaming plate die, which comprises a hexagonal wrench, wherein any cylinder of the hexagonal wrench is sleeved in a sleeving part at the top end of the wrench and is fixed by a fastening device, and the joint of the sleeving part and a handheld part is an arc surface. According to the invention, any one column of the inner hexagon wrench is arranged in the special wrench, and the inner hexagon wrench is rotated by the special wrench, so that the L-shaped inner hexagon wrench is prevented from being broken at the L-shaped position after being rotated vigorously.
Description
Technical Field
The invention relates to the technical field of hardware tools, in particular to a special wrench for a PVC (polyvinyl chloride) foaming plate die.
Background
The internal hexagonal wrench is also called an Allen wrench, and applies acting force to a screw through torque, so that the force intensity of a user is greatly reduced. It can be said that, among the installation tools involved in the modern furniture industry, socket head wrenches are preferred, although not the most common.
However, when a large hexagon socket countersunk head screw is tightened, the large hexagon socket countersunk head screw can be matched with the stress application pipe sleeve for use, and the hexagon socket wrench is usually broken at the L position due to the overlarge screwing distance.
Disclosure of Invention
According to the technical problem to be solved, the invention provides a special wrench for a PVC foam board die.
In order to achieve the purpose, the special wrench for the PVC foam board die comprises a hexagonal wrench, wherein any cylinder of the hexagonal wrench is sleeved in a sleeving part at the top end of the wrench and is fixed through a fastening device, and the joint of the sleeving part and the handheld part is an arc surface.
Furthermore, the center of the sleeve joint part is provided with a polygonal placing cavity corresponding to a hexagonal wrench, and the handheld part is a cylinder and is suitable for being used by a large and long force application pipe.
Furthermore, the perimeter of the hexagonal wrench placing cavity is at least 6mm larger than the perimeter of the corresponding hexagonal wrench cross section.
Furthermore, the arc length of the cambered surface is 28-32 mm.
Still further, the fastening device includes a fastening bolt and a fastening hole, the fastening hole penetrates through one side of the socket part, and the inner wall is provided with a threaded hole, and the threaded hole is in threaded connection with the fastening bolt.
Has the advantages that: according to the special wrench for the PVC foam board die, when the inner hexagonal countersunk head screw needs to be tightened, the inner hexagonal wrench cylinder is fixed in the special wrench, the special wrench drives the inner hexagonal wrench to rotate, and the L-shaped fracture phenomenon of the inner hexagonal wrench caused by overlarge screwing distance is avoided.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
FIG. 1 is a schematic diagram of the present invention.
FIG. 2 is a top view of the wrench of the present invention.
In the figure: 1 is a hexagonal wrench; 2 is a fastening bolt; 3 is a special spanner; 4 is a placing cavity; 5 is a fastening hole; and 6 is a cambered surface.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the scope of the present invention.
As shown in fig. 1 and 2, a wrench special for a PVC foam board mold comprises a hexagonal wrench, wherein any one cylinder of the hexagonal wrench 1 is sleeved in a sleeving part at the top end of the wrench 3 and is fixed by a fastening device, and a joint of the sleeving part and a handheld part is set to be an arc surface 6.
When the inner hexagon countersunk head screw needs to be tightened, one of the columns of the hexagon wrench 1 is penetrated in the hexagon wrench placing cavity 4 of the sleeving part of the wrench 3, the fastening bolt 2 is screwed up through thread fit to abut against the hexagon wrench 1, and the special wrench handle part is sleeved by the long stress application sleeve to rotate.
As shown in fig. 2, a polygonal placing cavity 4 corresponding to a hexagonal wrench is formed in the center of the sleeving part, and the handheld part is a cylinder and suitable for being used by a large and long force application pipe.
The hexagonal placing cavity 4 can meet the shape of a standard inner hexagonal wrench, and the defect that the L-shaped inner hexagonal wrench is most prone to being broken when the standard inner hexagonal wrench is pulled strongly in the using process is avoided to the maximum extent.
As shown in fig. 2, the circumference of the placing cavity 4 is at least 6mm larger than the corresponding hexagonal wrench 1.
Wherein, the circumference of the placing cavity 4 is at least 6mm larger than the circumference of the section of the corresponding hexagonal wrench 1, so that the placing cavity 4 is not blocked during installation and disassembly.
As shown in FIG. 2, the arc length of the arc surface 6 is 28-32 mm.
Wherein, the cambered surface 6 is arranged at the joint for reducing stress and increasing strength.
As shown in fig. 1 and 2, the fastening device includes a fastening bolt 2 and a fastening hole 5, the fastening hole 5 penetrates one side of the socket part, and the inner wall is provided with a threaded hole which is in threaded connection with the fastening bolt 2.
Wherein, through the screw-thread fit in fastening bolt 2 and the fastening hole 5, when rotating spanner 3, can prevent that hexagonal spanner 1 from rocking placing chamber 4 in.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.
The above examples are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention, and all designs identical or similar to the present invention are within the scope of the present invention.
