Description

Technical Field

[0001] This utility model relates to the field of guide rod technology, specifically a fracture-resistant guide rod with a lubrication structure. Background Technology

[0002] As a major component of guiding devices, guide rods have a wide range of applications. Guide rods can control the reciprocating motion trajectory of pistons. In the express delivery industry and factories, when using conveyor belts to transport goods, guide rods are also needed to protect and guide the goods, preventing them from falling off the conveyor belt and causing damage during movement.

[0003] According to a search, Chinese patent document, publication number CN219905709U, discloses a guide rod that is easy to assemble. By placing two guide rods together and screwing the insert of the first guide rod body into the groove of the second guide rod body, assembly is quick and the length of the guide rod is increased. When the guide rod needs to be moved, it can be disassembled into multiple guide rod bodies. The shorter guide rod bodies are easier to move and the length of the guide rod can be flexibly adjusted, reducing the limitations of the guide rod. When the guide rod is assembled, lubricating oil is injected into the U-shaped tube through the oil injection pipe and flows out through the oil outlet, spreading between the insert and the groove, which lubricates the insert and prevents rust at the insert, thus preventing the guide rod body from being unable to be disassembled. However, during the connection process, although the assembled components can achieve the connection effect, the internal structure is complex and difficult to manufacture. Moreover, lubricating oil needs to be injected into the U-shaped tube through the oil injection pipe and flow out through the oil outlet to spread between the insert and the groove to lubricate the insert and prevent rust. The cost of use is high. Furthermore, during use, the guide rod will wear and jam due to friction with the guide component, which also requires lubrication. Therefore, during use, manual lubrication and maintenance are required, which is troublesome and time-consuming. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a fracture-resistant guide rod with a lubrication structure. It has a self-lubricating effect, improves the ease of use of the guide rod and reduces the difficulty of manual maintenance. It also has the advantages of simple and quick assembly and low operating cost, thus solving the above-mentioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fracture-resistant guide rod with a lubrication structure, comprising a first guide rod and a second guide rod. The bottom side of the first guide rod is threadedly connected to the second guide rod, and the top side of the first guide rod is threadedly connected to a lubrication seat. An oil control seat is fixedly installed on the top side of the lubrication seat, and an oil reservoir is movably installed on the outer side of the oil control seat. A connecting frame is provided between the oil reservoir and the lubrication seat, and a sealing plug is installed on the top side of the oil reservoir by a snap-fit ​​mechanism.

[0008] Preferably, the first guide rod and the second guide rod are the same size and shape, and the first guide rod has a mating groove on its top side, a threaded hole on the inner side of the mating groove, a mating seat fixedly installed at the bottom end of the first guide rod, and a first threaded post fixedly installed on the bottom side of the mating seat.

[0009] With the above technical solution, during assembly, the mating seats on the first guide rod and the second guide rod are aligned with the mating grooves, and then they are snapped together and rotated to form a threaded connection for fixation, which facilitates assembly and extension. At the same time, the lubrication seat is installed at the top of the first guide rod in the same convenient way, which facilitates self-lubrication during use. Moreover, by snapping the mating grooves and mating seats together, the stability of the connection position can be effectively improved and the use cost can be reduced.

[0010] Preferably, a No. 2 threaded post is fixedly installed on the bottom side of the lubrication seat, and the No. 2 threaded post is connected to the inside of the threaded hole by thread. The top and bottom sides of the lubrication seat are respectively provided with oil storage grooves, and a number of oil holes are provided on the inner side of the oil storage grooves. The top side of the lubrication seat is respectively provided with a protective sleeve and a limiting hole.

[0011] Through the above technical solution, the No. 2 threaded column facilitates connection and fixation with the No. 1 guide rod, the oil reservoir facilitates the storage of lubricating oil and the oil hole facilitates oil delivery, and the protective sleeve and limiting hole facilitate the prevention of impurities from entering and improve the stability of the oil reservoir when it moves.

[0012] Preferably, the outer side of the oil control seat is provided with an oil outlet groove, and a total of six oil outlet grooves are provided, which are arranged in a ring at equal intervals, and the lowest end of the oil outlet groove is a sloping structure.

[0013] Through the above technical solution, the six oil outlet grooves arranged in a ring at equal intervals facilitate the transportation and discharge of lubricating oil. Moreover, the inclined structure at the bottom of the oil outlet grooves improves the oil transportation effect.

[0014] Preferably, the top side of the oil reservoir has a sealing hole, the inner side of the oil reservoir has an oil storage cavity, and the bottom side of the oil storage cavity has a through hole. The size and shape of the through hole match the oil control seat, and a cover plate is fixedly installed on the outer side of the oil reservoir.

[0015] With the above technical solution, during lubrication, the oil reservoir rises, and at this time the through hole slightly passes the oil outlet groove, allowing the lubricating oil to flow from the oil outlet groove to the inside of the oil reservoir groove. Then, it flows through the oil hole along the outside of the guide rod, thus lubricating the sliding parts during their movement. During this process, the oil reservoir rises and leaks out of the oil outlet groove at one end of the slope and then stops moving. This facilitates the delivery of lubricating oil and improves the stability of movement and the engagement accuracy under the action of the oil control seat.

[0016] Preferably, the connecting frame includes a top plate, a limiting rod, and a spring. There are a total of two top plates, and a limiting rod is fixedly installed between the top side of the top plate and the oil reservoir. A spring is installed between the top side of the top plate and the oil reservoir. Rubber pads are installed on the top and bottom sides of the top plate.

[0017] With the above technical solution, when the sliding part moves in the opposite direction, the oil reservoir is reset under the action of the spring, thereby blocking the oil from the oil outlet. Repeated operation facilitates automatic lubrication, reduces the difficulty of manual maintenance, and the limiting rod and limiting hole can effectively improve the movement stability of the oil reservoir. The rubber pad helps to reduce the impact force.

[0018] Compared with the prior art, this utility model provides a fracture-resistant guide rod with a lubrication structure, which has the following beneficial effects:

[0019] 1. This utility model uses the mating seats and mating grooves on the first guide rod and the second guide rod to be aligned, and then snapped and rotated to form a threaded connection and fixation, which facilitates assembly and extension. At the same time, the lubricating seat is installed at the top of the first guide rod in the same way, which facilitates self-lubrication during use. Moreover, the snapping installation of the mating groove and the mating seat can effectively improve the stability of the connection position and reduce the cost of use.

[0020] 2. In the process of using this utility model, when the sliding member slides on the outside of the guide rod, it moves to the top plate and continues to move, thereby pushing the connecting frame and the oil reservoir to rise. At this time, the through hole slightly passes the oil outlet groove, allowing the lubricating oil to flow from the oil outlet groove to the inside of the oil reservoir groove. Then, it flows along the outside of the guide rod through the oil hole, thus lubricating the sliding member during its movement. When the sliding member moves in the opposite direction, the oil reservoir groove is reset by the action of the spring, thereby blocking the oil from the oil outlet groove. Repeated operation facilitates automatic lubrication and reduces the difficulty of manual maintenance. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0028] like Figure 1-5 As shown, the present invention provides a fracture-resistant guide rod with a lubrication structure, including a first guide rod 1 and a second guide rod 2. The second guide rod 2 is threadedly connected to the bottom side of the first guide rod 1, and a lubrication seat 3 is threadedly connected to the top side of the first guide rod 1. An oil control seat 4 is fixedly installed on the top side of the lubrication seat 3, and an oil reservoir 5 is movably installed on the outer side of the oil control seat 4. A connecting frame 6 is provided between the oil reservoir 5 and the lubrication seat 3, and a sealing plug 7 is installed on the top side of the oil reservoir 5 by snap-fit.

[0029] Specifically, guide rod 1 and guide rod 2 are the same size and shape. Guide rod 1 has a meshing groove 101 on its top side and a threaded hole 1011 on its inner side. A meshing seat 102 is fixedly installed at the bottom end of guide rod 1, and a threaded post 1021 is fixedly installed on the bottom side of meshing seat 102. The advantage is that by aligning the meshing seats 102 on guide rod 1 and guide rod 2 with the meshing groove 101, and then engaging and rotating them for threaded connection and fixation, assembly and extension are convenient. Similarly, the lubrication seat 3 can be conveniently installed at the very top of guide rod 1, facilitating self-lubrication during use. Furthermore, the engagement of the meshing groove 101 and meshing seat 102 effectively improves the stability of the connection and reduces usage costs.

[0030] Specifically, a second threaded post 301 is fixedly installed on the bottom side of the lubrication seat 3. The second threaded post 301 is threadedly connected to the inner side of the threaded hole 1011. Oil storage grooves 302 are respectively provided on the top and bottom sides of the lubrication seat 3. Several oil holes 3021 are equidistantly arranged on the inner side of the oil storage grooves 302. A protective sleeve 303 and a limiting hole 304 are respectively provided on the top side of the lubrication seat 3. The advantages are that the second threaded post 301 facilitates connection and fixation with the first guide rod 1; the oil storage groove 302 facilitates the storage of lubricating oil and the oil holes 3021 facilitate oil delivery; and the protective sleeve 303 and the limiting hole 304 help prevent impurities from entering and improve the stability of the oil storage seat 5 during movement.

[0031] Specifically, the outer side of the oil control seat 4 is provided with six oil outlet grooves 401, which are arranged in a ring at equal intervals, and the lower end of the oil outlet grooves 401 is sloping. The advantage is that the six oil outlet grooves 401 arranged in a ring at equal intervals facilitate the delivery and discharge of lubricating oil, and the sloping structure at the lower end of the oil outlet grooves 401 improves the oil delivery efficiency. Example 2

[0032] like Figure 1-5As shown, this is an improvement on the previous embodiment. Specifically, a sealing hole 501 is provided on the top side of the oil reservoir 5, an oil storage cavity 502 is provided on the inner side of the oil reservoir 5, and a through hole 503 is provided on the bottom side of the oil storage cavity 502. The size and shape of the through hole 503 match the oil control seat 4, and a cover plate 504 is fixedly installed on the outer side of the oil reservoir 5. The advantage is that when the oil reservoir 5 rises, the through hole 503 slightly passes the oil outlet groove 401, allowing the lubricating oil to flow from the oil outlet groove 401 to the inner side of the oil storage groove 302. Then, it flows along the outer side of the guide rod through the oil hole 3021, thereby lubricating the sliding part during its movement. During this process, the oil reservoir 5 rises and leaks out of the oil outlet groove 401 at one end of the slope and stops moving. This facilitates the delivery of lubricating oil and improves the movement stability and engagement accuracy under the action of the oil control seat 4.

[0033] Specifically, the connecting frame 6 includes a top plate 601, a limiting rod 602, and a spring 603. Two top plates 601 are provided, and the limiting rod 602 is fixedly installed between the top side of the top plate 601 and the oil reservoir 5. A spring 603 is installed between the top side of the top plate 601 and the oil reservoir 5. Rubber pads are provided on the top and bottom sides of the top plate 601. The advantage is that by moving the sliding member in the opposite direction, the oil reservoir 5 is reset under the action of the spring 603, thereby blocking the oil outlet 401 from flowing out. Repeated operation facilitates automatic lubrication, reducing the difficulty of manual maintenance. Furthermore, the limiting rod 602 and the limiting hole 304 effectively improve the movement stability of the oil reservoir 5.

[0034] In use, the mating seats 102 on guide rod 1 and guide rod 2 are aligned with the mating grooves 101, and then locked and rotated for threaded connection and fixation, facilitating assembly and extension. Simultaneously, the lubrication seat 3 is conveniently installed at the top of guide rod 1, enabling self-lubrication during use. Furthermore, the engagement of the mating groove 101 and mating seat 102 effectively improves the stability of the connection. Then, during use, when the sliding component slides on the outside of the guide rod, the… The sliding member moves to the top plate 601 and continues to move, thereby pushing the connecting frame 6 and the oil reservoir 5 to rise. At this time, the through hole 503 passes slightly past the oil outlet groove 401, allowing the lubricating oil to flow from the oil outlet groove 401 to the inside of the oil reservoir 302. Then, it flows along the outside of the guide rod through the oil hole 3021, thus lubricating the sliding member during its movement. When the sliding member moves in the opposite direction, the oil reservoir 5 is reset under the action of the spring 603, thereby blocking the oil outlet groove 401 from discharging oil. Repeated operation facilitates automatic lubrication and reduces the difficulty of manual maintenance.
