Description

Technical Field

[0001] This utility model relates to the field of connecting component technology, specifically a modular adjustable hydraulic cylinder double-hole hinge connecting component. Background Technology

[0002] Hydraulic cylinders, commonly known as hydraulic cylinders, are core components of hydraulic systems. They are primarily responsible for efficiently converting hydraulic energy into mechanical energy, thereby achieving linear reciprocating motion or oscillating motion. Common types of hydraulic cylinders include single-acting cylinders, double-acting cylinders, and multi-stage cylinders. Hydraulic cylinders are fixed in a specific position by hinged connecting components, ensuring that they do not move unexpectedly during operation, thus improving work efficiency.

[0003] When using hinged lug connections, a hinged lug connection assembly is used for fixation. One end of the lug connects to the piston rod or cylinder barrel of the hydraulic cylinder, while the other end connects to other equipment via a pin. Different sizes of hydraulic cylinders require corresponding connection assemblies, making a single hinged lug connection assembly insufficient to meet the fixation requirements of various hydraulic cylinders. The lugs used need to meet high strength and wear resistance to withstand large loads and frequent movements. The insufficient tightness between double-hole hinges makes them difficult to secure effectively. Therefore, we propose a modular adjustable double-hole hinged lug connection assembly for hydraulic cylinders to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a modular adjustable hydraulic cylinder double-hole hinge lug connection assembly, which solves the problems of existing hinge lug connection assemblies being unable to adjust the spacing to suit different hydraulic cylinders during use, and the insufficient tightness of the hinge lug connection.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a modular adjustable hydraulic cylinder double-hole hinge lug connection assembly, comprising a base structure, the base structure including a mounting seat, the mounting seat having square mounting openings around its top perimeter, and insertion holes on both outer sides of the mounting seat, with an adjusting column installed inside the insertion hole, and a sleeve fitted over the adjusting column; a fixing seat is connected to the top of the mounting seat via a protrusion, and a hinge lug assembly is provided on the top of the fixing seat; the hinge lug assembly includes a hinge lug plate one, with pins installed around its inner perimeter, the pins being internally connected to a pin shaft in a cover plate structure; the cover plate structure includes a hinge lug plate two, with a pin shaft at its bottom, and a bushing installed on the outside of the hinge lug plate two, the bushing containing a pin shaft and an inner ring.

[0007] By setting an adjustable base structure at the bottom of the hinge assembly, the corresponding spacing can be adjusted according to the specifications of the hydraulic cylinder to improve the application range of the connecting assembly. The different angles of the protrusion at the bottom of the fixing seat and the mounting seat enable the connecting assembly to be installed from the front and the side, which facilitates corresponding installation and improves the flexibility of the connecting assembly.

[0008] Furthermore, the mounting base has two sets of symmetrically distributed mounting holes. Square mounting openings are evenly distributed around the bottom of the mounting base. Circular insertion holes are fixedly opened on the outer side of the mounting base. The insertion holes extend to the symmetrical plane. An adjusting column is movably installed inside the insertion hole. A telescopic spring is sleeved on the outside of the adjusting column. A sleeve is movably installed on the outside of the adjusting column. The sleeve is fitted and connected to the outer side of the mounting base.

[0009] Furthermore, the top of the mounting base is movably connected to the fixed base via a protrusion, and protrusions are symmetrically fixedly installed on both sides of the bottom of the fixed base. The protrusions are the same size as the square mounting opening, and the top of the fixed base is connected to the hinge plate in the hinge assembly.

[0010] Furthermore, a pin is fixedly provided around the inner side of the hinge plate, and the pin is provided in several groups arranged in a circumferential array at equal distances. The pin is provided with a circular insertion port inside, and the insertion port in the pin is movably connected to the insertion shaft in the cover plate structure.

[0011] Furthermore, the cover plate structure includes a second hinge plate, and insert shafts are fixedly installed around the bottom of the second hinge plate. The insert shafts are distributed and movably connected to the insertion ports.

[0012] Furthermore, a bushing is movably mounted on the outside of the hinge plate. The bushing has two sets of bolt holes that are movably connected by pins. Bolt holes are symmetrically opened on both sides of the outer side of the bushing, and fixing bolts are installed inside the bolt holes.

[0013] Furthermore, an inner ring is movably mounted on the top of the pin, and the inner ring is distributed in a circular pattern inside the bushing.

[0014] This utility model has the following beneficial effects:

[0015] (1) This utility model: By setting an adjustable base structure at the bottom of the hinge assembly, the corresponding spacing can be adjusted according to the specifications of the hydraulic cylinder to make it suitable, thereby improving the application range of the connecting assembly. The different angles of the protrusion at the bottom of the fixed seat and the mounting seat enable the connecting assembly to be installed from the front and the side, which facilitates corresponding installation and use, and improves the flexibility of the connecting assembly.

[0016] (2) This utility model: By providing a pin and a shaft at the bottom of the hinge assembly, the hinge plate one and the hinge plate two are fixedly installed. The connection tightness between the hinge assembly is improved by multiple sets of pins and shafts, so that the connecting assembly can ensure normal fixing function during use, and improve tightness and stability.

An adjusting column 103 is installed inside the insertion hole, and a sleeve 104 is fitted around the adjusting column 103. A fixing base 105 is connected to the top of the mounting base 101 through a protrusion 106. A hinge lug assembly 2 is provided on the top of the fixing base 105. The hinge lug assembly 2 includes a hinge lug plate 201, with pins 202 installed around the inner perimeter of the hinge lug plate 201. The pins 202 are connected to the insertion shaft 302 in the cover plate structure 3. The cover plate structure 3 includes a second hinge lug plate 301, with the insertion shaft 302 at the bottom of the second hinge lug plate 301. A bushing 401 is installed on the outside of the second hinge lug plate 301, and a pin 402 and an inner ring 403 are provided inside the bushing 401.

[0028] By setting an adjustable base structure 1 at the bottom of the hinge assembly 2, the corresponding spacing can be adjusted according to the specifications of the hydraulic cylinder to improve the application range of the connecting assembly. The different angles of the protrusion 106 at the bottom of the fixed seat 105 and the mounting seat 101 enable the connecting assembly to be installed from the front and from the side, which facilitates corresponding installation and improves the flexibility of the connecting assembly.

[0029] The mounting base 101 has two sets of symmetrically distributed square mounting openings 102 evenly distributed around the bottom of the mounting base 101. A circular insertion hole is fixedly opened on the outside of the mounting base 101, extending to the symmetrical plane. An adjusting post 103 is movably installed inside the insertion hole. A telescopic spring is sleeved on the outside of the adjusting post 103. A sleeve 104 is movably installed on the outside of the adjusting post 103, and the sleeve 104 is fitted and connected to the outer side of the mounting base 101.

[0030] The top of the mounting base 101 is movably connected to the fixed base 105 via a protrusion 106. The fixed base 105 has protrusions 106 symmetrically fixed on both sides of its bottom. The protrusions 106 are the same size as the square mounting opening 102. The top of the fixed base 105 is connected to the hinge plate 201 in the hinge assembly 2.

[0031] By providing a pin 202 at the bottom of the hinge assembly 2 to cooperate with the insertion shaft 302, the hinge plate 1 201 and the hinge plate 2 301 are fixedly installed. The pin 202 is fixedly provided around the inner side of the hinge plate 1 201. The pin 202 has several groups of pins arranged in a circumferential array at equal distances. The pin 202 has a circular insertion port inside. The insertion port in the pin 202 is movably connected to the insertion shaft 302 in the cover plate structure 3.

[0032] The cover plate structure 3 includes a hinge plate 2 301. Insert shafts 302 are fixedly installed around the bottom of the hinge plate 2 301. The insert shafts 302 are distributed and movably connected to the insertion port. The connection tightness between the hinge plate assembly 2 is improved by multiple sets of pins 202 and insert shafts 302, so that the connection assembly can ensure normal fixing function during use, and improve tightness and stability.

[0033] The hinge plate 301 is externally mounted with a bushing 401. The bushing 401 has two sets of bushings that are movably connected by pins 402. Bolt holes are symmetrically opened on both sides of the outer side of the bushing 401, and fixing bolts 303 are installed inside the bolt holes.

[0034] An inner ring 403 is movably mounted on the top of the pin 402, and the inner ring 403 is distributed in a circular pattern inside the bushing 401.

[0035] Working principle: During use, the spacing between the two sets of mounting seats 101 in the base structure 1 is adjusted according to the size of the hydraulic cylinder to accommodate the piston rod position of the hydraulic cylinder for fixing, thereby increasing the application range of the connecting assembly. By installing the protrusion 106 at the bottom of the fixing seat 105 into the square mounting opening 102 inside the mounting seat 101, the hinge plate 201 and hinge plate 301 in the hinge assembly 2 are fixed to the corresponding positions of the piston rod of the hydraulic cylinder. The bushing 401 and pin 402 reduce friction and wear with the hinge assembly 2, and the inner ring 403 strengthens the fixing effect on the hydraulic cylinder. The hinge plate 201 and hinge plate 301 have multiple sets of pins 202 and pins 302 connected to each other on their inner sides, making the hinge connecting assembly tightly connected and improving the fastening effect.
