Description

Technical Field

[0001] The present application relates to the technical field of nitrogen springs, and in particular to a nitrogen spring that is easy to install. Background Art

[0002] The mold-specific nitrogen spring, referred to as the die nitrogen spring or nitrogen spring or nitrogen cylinder or nitrogen cylinder, is a new type of elastic component using high-pressure nitrogen as the working medium. It is small in size, large in elasticity, long in stroke, stable in operation, precisely manufactured, long in service life, with a gentle elastic curve, and no need for pre-tightening, etc. It can perform tasks that are difficult to accomplish with conventional elastic components such as metal springs, rubbers, and air cushions, simplify mold design and manufacturing, facilitate mold installation and adjustment, extend mold service life, and ensure stable product quality. It can also be designed into a nitrogen spring system and work as part of the mold. It can easily achieve constant pressure and delayed action in the system. It is a new generation of the most ideal elastic component with flexible performance.

[0003] Existing ammonia springs are fixed by multiple bolts during installation, which is time-consuming and laborious to install and remove. In addition, nitrogen springs on the market are prone to overloading when the plug rod moves back and forth during use, which causes the plug rod to scratch the cylinder body and leak, thereby reducing the service life of the product. Therefore, those skilled in the art provide a nitrogen spring that is easy to install to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the present application provides a nitrogen spring that is easy to install.

[0005] The present application provides a nitrogen spring that is easy to install and adopts the following technical solution:

[0006] A nitrogen spring that is easy to install comprises a cylinder, a mounting assembly is arranged near the bottom of the cylinder, the mounting assembly comprises a disc, three mounting holes are arranged in an annular shape on the upper end of the disc, a mounting column is fixedly installed on the upper end of the disc between two adjacent mounting holes, a positioning hole is arranged on the outside of the mounting column, a connecting block is fixedly installed in an annular shape near the bottom of the cylinder, a through hole is arranged on the upper end of the connecting block, and a positioning rod is passed through one side of the connecting block.

[0007] Preferably, the mounting column is inserted into the through hole, and a return spring is sleeved on the outside of the positioning rod.

[0008] Preferably, one end of the return spring is fixedly connected to one end of the positioning rod, the other end of the return spring is fixedly connected to the outside of the connection block, and the positioning rod passes through the interior of the positioning hole.

[0009] Preferably, a piston column movably penetrates the upper end of the cylinder, and a dust cover is fixedly installed on the upper end of the cylinder, and the dust cover is wrapped around the outside of the piston column.

[0010] Preferably, an anti-deflection component is fixedly installed on the outside of the cylinder, and the anti-deflection component includes two fixing blocks, which are symmetrically fixed on the outside of the cylinder and fixedly connected to the cylinder by positioning bolts.

[0011] Preferably, a buffer sleeve rod is fixedly mounted on the upper end of the fixed block, and a semicircular piece is fixedly mounted on the top of the buffer sleeve rod.

[0012] Preferably, the two semicircular pieces are wrapped around the outside of the piston column, and a guide pad is fixedly installed on the inner side of the semicircular piece.

[0013] In summary, the present application includes the following beneficial technical effects: by setting the installation assembly, after the through holes of the three connection blocks are sleeved on the outside of the installation column, the positioning rod is pulled outward to put the reset spring in a stretched state, and when the installation column and the through hole are completely penetrated, the positioning rod is loosened so that one end of the positioning rod just penetrates the positioning hole to complete the fixing of the cylinder. Compared with the traditional method of fixing the nitrogen spring by multiple bolts, the installation assembly is more convenient for installation and disassembly;

[0014] Through the anti-deflection assembly, when the piston column moves up and down, the two semicircular pieces and the guide pad guide the piston column, thereby realizing the vertical movement of the piston column and preventing deviation. After the buffer sleeve moves downward, the buffer spring inside the buffer sleeve is squeezed, thereby sharing the impact of external force on the inside of the cylinder, protecting the cylinder from starting, and increasing the service life of the nitrogen spring. The entire anti-deflection assembly can be disassembled and replaced. BRIEF DESCRIPTION OF THE DRAWINGS

A mounting column 13 is fixedly installed between two adjacent mounting holes 12 at the upper end of the disc 11, and a positioning hole 15 is opened on the outside of the mounting column 13. A connecting block 14 is fixedly installed in an annular manner near the bottom of the cylinder 1, and a through hole 16 is opened on the upper end of the connecting block 14. The connecting block 1 A positioning rod 17 is passed through one side of 4. First, when installing the cylinder 1, the disc 11 is fixed at a certain place through the mounting hole 12, and then the through holes 16 of the three connecting blocks 14 are sleeved on the outside of the mounting column 13 through the provided mounting assembly 4. At this time, the positioning rod 17 is pulled outward to put the reset spring 18 in a stretched state. When the mounting column 13 and the through hole 16 are completely penetrated, the positioning rod 17 is loosened so that one end of the positioning rod 17 just penetrates the positioning hole 15 to complete the fixing of the cylinder 1.

Through the anti-deflection component 3, when the piston column 2 moves up and down, the two semicircular pieces 9 and the guide pad 10 guide the piston column 2, thereby realizing the vertical movement of the piston column 2 and preventing deviation. After the buffer sleeve 8 moves downward, the buffer spring inside the buffer sleeve 8 is squeezed, thereby sharing the impact of external force on the inside of the cylinder 1, and protecting the cylinder 1 from starting, thereby increasing the service life of the nitrogen spring, and the entire anti-deflection component 3 can be disassembled and replaced.

[0028] The implementation principle of a nitrogen spring that is easy to install in the embodiment of the present application is as follows: first, when installing the cylinder 1, the disc 11 is fixed at a certain place through the mounting hole 12, and then the through holes 16 of the three connecting blocks 14 are sleeved on the outside of the mounting column 13 through the provided mounting assembly 4. At this time, the positioning rod 17 is pulled outward to put the reset spring 18 in a stretched state. After the mounting column 13 and the through hole 16 are completely penetrated, the positioning rod 17 is loosened so that one end of the positioning rod 17 just penetrates the positioning hole 15 to complete the fixation of the cylinder 1. Through the provided anti-bias assembly 3, when the piston column 2 moves up and down, the two semicircular pieces 9 and the guide pad 10 guide the piston column 2, thereby realizing the movement of the piston column 2 in the vertical direction and preventing deviation. After the buffer sleeve 8 moves downward, the buffer spring inside the buffer sleeve 8 is squeezed, thereby sharing the impact of the external force on the inside of the cylinder 1, and protecting the cylinder 1 from starting, thereby increasing the service life of the nitrogen spring, and the entire anti-bias assembly 3 can be disassembled and replaced.
