[0028] To solve the problems in the prior art, the embodiments of the present application provide a multifunctional key.
[0029] As Figure 1 shown, a multifunctional key comprises a T-shaped wrench 1, a first key 2, a second key 3, a third key 4 and a magnetic member 5; the T-shaped wrench 1 is provided with one or more mounting positions 11; the magnetic member 5 is mounted on the mounting position 11; the first key 2 is detachably mounted on a first end 12 of the T-shaped wrench 1; the second key 3 is detachably mounted on a second end 13 of the T-shaped wrench 1; and the third key 4 is detachably mounted on a third end 14 of the T-shaped wrench 1.
[0030] The multifunctional key of the utility model, based on setting the first key 2, the second key 3 and the third key 4 on the three ends of the T-shaped wrench 1 respectively, can open three different locks; by setting the magnetic member 5 in the mounting position 11, the multifunctional key can be fixed by magnetic attraction, which is convenient for storage and use.
[0031] In some preferred embodiments, as Figure 2 and Figure 3 shown, the first key 2 is a hexagonal key; the end face of the first end 12 is provided with a first accommodating part 121; the first accommodating part 121 is recessed inward from the end face of the first end 12, the cross section shape of the first accommodating part 121 perpendicular to the depth direction is a regular polygon, which is used for mounting the tail end of the first key 2 (i.e. the end opposite to the key head), such as setting the tail end of the first key 2 in the shape of the first accommodating part 121, and is used for tightening the regular polygon bolt; preferably, the cross section shape of the first accommodating part 121 perpendicular to the depth direction is a square or a regular hexagon, so as to form a structure similar to a socket wrench, which can be used as a wrench for loosening the bolt.
[0032] In some preferred embodiments, the second key 3 is a hexagonal key; the end face of the second end 13 is provided with a second accommodating part 131; the second accommodating part 131 is recessed inward from the end face of the second end 13, the cross section shape of the second accommodating part 131 perpendicular to the depth direction is a regular polygon, which is used for mounting the tail end of the second key 3, and is used for tightening the regular polygon bolt; preferably, the cross section shape of the second accommodating part 131 perpendicular to the depth direction is a square or a regular hexagon, so as to form a structure similar to a socket wrench, which can be used as a wrench for loosening the bolt.
[0033] In some preferred embodiments, the third key 4 is a twist lock key, such as a straight twist lock key, which is connected with the third end 14 of the T-shaped wrench 1 by a bolt; specifically, the third end 14 of the T-shaped wrench 1 has a mounting notch, and the tail end of the third key 4 is mounted in the mounting notch.
[0034] In some preferred embodiments, the material of the T-shaped wrench 1 is stainless steel, such as 30Cr13 stainless steel, which has good atmospheric resistance, certain wear resistance and corrosion resistance, and high hardness.
[0035] In some preferred embodiments, the mounting position 11 is a through hole; since the magnetic suction member 5 is installed in the through hole, it is convenient to install the magnetic suction member 5 on the one hand, and the magnetic attraction and fixing effect of the magnetic suction member 5 can be improved on the other hand.
[0036] In some preferred embodiments, the end face of the first end 12 is recessed inward to form a first receiving portion 121; the end face of the second end 13 is recessed inward to form a second receiving portion 131; the cross-sectional shape of the first receiving portion 121 and the second receiving portion 131 perpendicular to the depth direction is a regular hexagon with different sizes, which are used to be inserted and connected with the first key 2 and the second key 3 respectively; the first key 2 and the second key 3 are internal hexagonal keys with different sizes, and one end of the first key 2 and / or the second key 3 can be adapted to be inserted into the first receiving portion 121, and the other end can be adapted to be inserted into the second receiving portion 131, that is, three different sizes of internal hexagonal wrenches can be realized. For example, both ends of the first key 2 are hexagonal prisms with different sizes, and the key end of the second key 3 has different sizes from both ends of the first key 2; the second key 3 is similar, and will not be described in detail.
[0037] In some preferred embodiments, such as Figure 4 and Figure 5 As shown, the T-shaped wrench 1 includes a first rod 15 and a second rod 16. The first rod 15 has a non-circular cross-section, such as an ellipse or polygon, and its two ends are a first end 12 and a second end 13, respectively. The second rod 16 is perpendicular to the first rod 15, with one end fitted onto the first rod 15, which restricts the second rod 16 from rotating around the axis of the first rod 15 and from moving along the first rod 15. The other end is a third end 14. Based on this, the first rod 15 and the second rod 16 can be separated and stored, reducing the size and making storage easier. Furthermore, the second rod 16 can move along the first rod 15, which can change the insertion depth of the first key 2 and the second key 3, thus increasing its usability.
[0038] In some preferred embodiments, the end of the second rod 16 is provided with a regular polygonal hole 17; the cross-sectional shape of the first rod 15 is adapted to fit and be inserted into the regular polygonal hole 17, and the two cooperate to restrict the second rod 16 from rotating about the first rod 15 axially; preferably, the size of the regular polygonal hole 17 is adapted to the size of the bolt so that it can be used as a wrench.
[0039] Preferably, the regular polygonal hole 17 is a double hexagonal hole, which is formed by rotating and misaligning two coaxial regular hexagonal holes, thus forming a structure similar to a box wrench, so that it is easier to put on the bolt when used as a wrench.
[0040] Preferably, the second rod 16 is provided with a mounting position 11 on the side near the polygonal hole 17; based on this, when the position of the second rod 16 is adjusted to that of the first rod 15, the second rod 16 and the first rod 15 have a certain magnetic attraction, which can achieve a small adjustment, and the fixed position also makes it easy to align and unlock during use.
[0041] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
