Description
Technical Field
The utility model belongs to the technical field of the double-screw bolt, specifically speaking relate to a cross nonstandard double-end stud.
Background
Studs, also known as studs or studs. The double-end stud in the prior art has threads at two ends and a polished rod in the middle, and the diameters of the two ends and the middle are the same. Studs are used very widely in machine equipment, the most typical use being: the foundation studs or the thick connection of places similar to the foundation studs are mainly used for occasions where one of connected parts is large in thickness and compact in required structure or cannot be connected by bolts due to frequent disassembly when common bolts cannot be used for connection.
The two-end threads of the stud bolt are connected with the threads of the connected piece in a poor stability, and the phenomenon of looseness can occur under the influence of factors such as vibration.
In addition, the screw lengths of the two ends of the double-ended stud in the prior art are the same, so that the double-ended stud cannot be used when the lengths of the two ends are required to be unequal in special cases.
Disclosure of Invention
The utility model aims at providing a cross nonstandard stud, its stability is good, convenient dismantlement.
In order to solve the technical problem, the purpose of the utility model is to realize like this:
a cross-shaped non-standard stud comprises a screw, wherein a first connecting plate is arranged on the screw, and the axis of the screw is mutually perpendicular to the central line of the first connecting plate to form a cross shape; the first connecting plate divides the screw into a first screw section and a second screw section, and the length of the first screw section is half of that of the second screw section; two countersunk holes are formed in the first connecting plate from the second screw section to the first screw section, and the two countersunk holes are respectively located on two sides of the screw; two end faces of the screw rod are inwards sunken to form a cross-shaped groove, and the lower surface of the first connecting plate is parallel to the end face of the screw rod.
On the basis of the above scheme and as a preferable scheme of the scheme: the length of the first screw rod is 3-4 cm, and the length of the second screw rod is 6-8 cm.
On the basis of the above scheme and as a preferable scheme of the scheme: the diameter of the screw is 10-20 mm, and the length of the screw is 10-15 cm.
Compared with the prior art, the utility model outstanding and profitable technological effect is:
the utility model discloses a cross nonstandard stud, including the screw rod, add first connecting plate on the screw rod, first connecting plate and screw rod are the cross, and first connecting plate separates the screw rod into first screw rod section, second screw rod section, can adapt to the connecting piece of different screw depth, has seted up the counter sink on the first connecting plate, and the counter sink is followed second screw rod section towards first screw rod section, can make shorter first screw rod section be connected with the connecting piece, and stability is better, connects more firmly; the cross grooves are arranged on the two end faces of the screw rod, so that the screw rod is convenient to disassemble and assemble; the lower surface of first connecting plate is parallel with the terminal surface of screw rod, and is more level and more smooth during the connection.

Detailed Description
In the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like refer to the orientation or position relationship shown in the drawings, or the orientation or position relationship that the product of the present invention is usually placed when in use, or the orientation or position relationship that one skilled in the art conventionally understands, and are only for convenience of describing the present invention and simplifying the description, but do not refer to or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
The present invention will be further described with reference to the following detailed description;
the embodiment provides a cross-shaped non-standard stud, which comprises a screw rod 01, wherein the diameter of the screw rod is 10-12 mm, the length of the screw rod is 10-15 cm, a first connecting plate 02 is arranged on the screw rod and fixed on the screw rod to be integrally formed, a bearing of the screw rod is mutually perpendicular to the central line of the first connecting plate to form a cross shape, and the cross-shaped stud can ensure that connecting pieces at two ends are stably connected;
the first connecting plate divides the screw into a first screw section 010 and a second screw section 011, the length of the first screw section is half of that of the second screw section, the length of the first screw section is 3-4 cm, and the length of the second screw section is 6-8 cm, so that connecting pieces with different thread hole depths at two ends can be met; the first connecting plate is a cuboid, and the width of the first connecting plate is the same as the diameter of the screw;
two countersunk holes 020 are formed in the first connecting plate from the second screw section to the first screw section, and are respectively positioned on two sides of the screw; the countersunk head screw passes through the countersunk head hole to be connected with the connecting piece, so that the connecting strength between the connecting piece and the utility model is increased, the connecting piece is more stable, and the looseness is not easy to occur; because the length of the first screw section is smaller than that of the second screw section, the direction of the countersunk hole is set to face the first screw section, so that the connection stability on the first screw section is improved, and the firmness is better;
the two end faces of the screw rod are inwards sunken to form a cross-shaped groove 012, and the cross-shaped groove can be convenient for an operator to screw in the connecting piece, so that the connecting piece is quick to disassemble and assemble, convenient and labor-saving, and more practical; the lower surface of first connecting plate is parallel with the terminal surface of screw rod, can be more parallel and level with the connecting piece.
The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
