Abstract
Description
A long oval locking hoop Technical Field
[0001] This technology belongs to the field of fasteners for pipe fittings in metal machinery. Background Technology
[0002] Hose clamps (also known as metal clamps) used in both domestic and mechanical applications are circular in shape and are typically wrapped around rigid pipes to lock the flexible hoses on the rigid pipes, preventing leaks at the connection point. Currently, there are two types of hose clamps: double-wire and flat-band. Both rely on the bolts and threads on the clamp to tighten or loosen. The flat-band type has threads pressed into the flat band, and the threaded bolt engages with the threaded grooves on the band. Rotating the bolt tightens or loosens the band, thus securing the pipe. Since the pipe is circular, the bolt base is arc-shaped, and the band used for tightening and loosening is also arc-shaped. The biggest advantage of hose clamps is their ease and speed of assembly and disassembly, as well as their high reliability. However, in daily life and work, it is common to need to connect two pipes or two parts in parallel, requiring easy assembly and disassembly. Current circular hose clamps do not meet these requirements, and even when assembled, the effect is often unsatisfactory. Summary of the Invention
[0003] This invention discloses an elongated elliptical locking clamp with semi-circular arc edges at both ends and a straight edge in the middle. The bolt base is straight, and the tightening and loosening flat band is also straight, which can conveniently, quickly and reliably fasten two round tubes together.
[0004] A type of elongated elliptical locking clamp is characterized by the following: the locking clamp is made of a galvanized steel or stainless steel flat strip with a thickness of 1mm and a width of 12mm. Both ends are semi-circular clamps with a diameter equal to the diameter of the pipe being locked. The middle is a straight clamp with a length equal to the center distance between the two pipes being locked. These are connected together to form an elongated elliptical locking clamp. A bolt base is embedded at the junction of the straight clamp and the semi-circular clamp. An adjustable M8 bolt is located inside the bolt base. The bolt head has a cross and slotted groove. The tail of the clamp and the section of the bolt base have a pressed threaded groove. The thread of the M8 bolt is engaged in the threaded groove. Rotating the bolt tightens or loosens the locking clamp.
[0005] With this design, the locking clamp has round semicircular ends, the diameter of which is the diameter of the pipe, and a straight clamp in the middle. By rotating the bolt left or right with a screwdriver, the clamp can be tightened or loosened. The semicircular clamps securely fasten the two pipes together conveniently, quickly, and reliably, and they can also be easily and quickly disassembled. This provides a reliable accessory for situations where two pipes need to work together, require a certain amount of time, and need to be disassembled. Attached Figure Description

[0007] Figure 2 shows a side view of an elongated elliptical locking hoop.
[0008] In Figures 1 and 2, 1 is a semi-circular hoop, 2 is a bolt, 3 is a bolt seat, 4 is a tail hoop, 5 is a straight hoop, and 6 is a threaded groove. Detailed Implementation
[0009] The method of implementing this utility model is described in detail below with reference to the accompanying drawings. Figure 1 is a front view of an elongated elliptical locking clamp, and Figure 2 is a side view of an elongated elliptical locking clamp. The drawings are drawn at a 1:1 scale. The tail clamp 4 in Figure 2 is intentionally drawn slightly obliquely to illustrate its existence and length. The elongated elliptical locking clamp is made of galvanized steel or stainless steel flat strip with a thickness of 1mm and a width of 12mm. It is a commonly used rust-free material. The two ends are semi-circular clamps 1, the diameter of which is the diameter of the pipe being locked. The middle is a straight clamp 5, the length of which is the center distance between the two locked pipes. This arrangement ensures that the clamps are at their shortest distance when clamping the two pipes. The semi-circular clamps 1 are in full contact with the pipes for fastening, and the circular surface of the semi-circular clamp 1 fits seamlessly with the pipe surface. The long elliptical locking clamp achieves reliable mechanical fastening. The bolt seat 3 is placed at the junction of one end of the straight clamp 5 and the semi-circular clamp 1. This placement minimizes the impact on appearance and facilitates the rotation of the bolt 2. The bolt 2 is placed inside the bolt seat 3 and is enclosed by it, allowing it to rotate only left and right within the seat. The bolt 2 has an M8 thread, and the bolt head has a cross and slotted groove for easy rotation with a cross or slotted screwdriver. The flat band at the last section of the bolt seat 3 and the tail clamp 4 have pressed threaded grooves with the same angle as the bolt 2 thread. The bolt 2 thread is engaged in the threaded grooves. When the bolt 2 rotates, the tail clamp 4 can be retracted or released under the action of the thread, achieving the locking or loosening of the long elliptical locking clamp.
[0010] The advantages of this setup are: by rotating the Phillips or slotted head of the bolt with a screwdriver, the flat band of the locking clamp can be tightened or loosened. The long oval clamp allows for convenient, quick, and reliable fastening of two pipes together, and also convenient and quick disassembly. This setup can be configured with multiple specifications according to pipe size. In practical applications, when encountering pipes with slightly different diameters within a 5mm range, the clamps in this setup can still be used. Therefore, setting a specification for every 5mm can cover all pipe combinations. With the rapid development of technology and the increasing variety of new products, the required types of accessories are also increasing. This technology adds an assembly component to the field of mechanical assembly.
[0011] The above description is merely a preferred embodiment of the present invention and is illustrative rather than restrictive. Many dimensions and shapes can be appropriately modified to achieve the same effect as the hose clamp. This is readily understood by those skilled in the art. Many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, and all of these will be within the protection scope of the present invention.
