Description

Technical Field

[0001] This utility model relates to the field of hydraulic lock technology, and in particular to a one-way hydraulic lock. Background Technology

[0002] Hydraulic locks, as components of hydraulic systems, function to lock the oil circuit, preventing the flow of oil and ensuring that the cylinder remains stationary even under external loads, thus guaranteeing the safe operation of the hydraulic equipment. In practical applications of large-scale hydraulic systems, multiple hydraulic locks need to be used side-by-side. However, each hydraulic lock is used individually and is not connected to the others; each lock needs to be individually fixed to form a row. This method of individually fixing the hydraulic locks is cumbersome and time-consuming. Utility Model Content

[0003] The purpose of this utility model is to solve the problem mentioned in the background art that the hydraulic locks are used individually and are not connected to each other. Each hydraulic lock needs to be fixed separately to form a row of hydraulic locks. The installation process of fixing the hydraulic locks individually is cumbersome and time-consuming.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A one-way hydraulic lock includes a body and a connecting assembly; the body has oil ports on both the upper and lower sides; the connecting assembly includes a connecting groove on one side of the body, and a plug is fixedly connected to the other side of the body, the plug being adapted to the connecting groove, and the plug and the connecting groove being fixed laterally.

[0006] Preferably, a limiting component is provided on the upper side of the main body. The limiting component includes a limiting block, which is slidably connected to the main body. A limiting groove is formed on the main body, and a plate extending from one side of the limiting block is inserted into the limiting groove.

[0007] Preferably, the limiting block and the insert block are located on the same side of the body, and the limiting groove and the connecting groove are located on the same side of the body.

[0008] Preferably, a slide rod is fixed on the main body, the slide rod slides in cooperation with the limiting block, and a limiting part is fixed at the end of the slide rod.

[0009] Preferably, a protrusion is fixedly connected to the side wall of the limiting groove, one side of the limiting block extends out of the plate, and a groove is formed on the side of the plate facing the anti-slip protrusion.

[0010] Preferably, the top surface of the limiting block has multiple anti-slip protrusions.

[0011] Preferably, the main body is provided with mounting plates on both the top and bottom, and the mounting plates are provided with mounting holes.

[0012] Preferably, the upper mounting plate is positioned to the right, and the lower mounting hole is positioned to the left.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The T-shaped connecting slot and plug design of the connecting components allows multiple one-way hydraulic locks to be easily spliced ​​laterally, changing the current situation where hydraulic locks are used individually and not connected, meeting the diverse application needs of hydraulic systems, and eliminating the need for each hydraulic lock to be fixed.

[0015] In the limiting assembly, the plate of the limiting block is inserted into the limiting groove, which realizes the fixation of the two bodies in the longitudinal direction. It works together with the connecting assembly for the transverse fixation so that the combination of multiple one-way hydraulic locks can remain stable in both the longitudinal and transverse directions.

[0016] The anti-slip protrusions on the top surface of the limit block facilitate the operator's movement of the limit block. At the same time, the cooperation between the protrusions on the side wall of the limit groove and the groove of the plate ensures that the limit block remains stable after being fixed, preventing the plate from shifting laterally and detaching. During maintenance, only the limit block needs to be slid and the mounting hole bolts need to be removed to easily take out the main body that needs maintenance in the middle. There is no need to disassemble the entire hydraulic lock assembly on a large scale, which greatly reduces the difficulty and workload of maintenance, improves the maintenance efficiency of the equipment, and reduces downtime.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0031] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0032] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0033] Please see Figures 1-10A one-way hydraulic lock includes a body 1 and a connecting component 2. Oil ports are provided on the upper and lower sides of the body 1. The structure of the body 1 and its internal structure is prior art and will not be described further.

[0034] The connecting component 2 includes a connecting groove 21 opened on one side of the main body 1. The connecting groove 21 is a vertical through groove and is T-shaped. A plug 22 is fixedly connected to the other side of the main body 1. The plug 22 is also T-shaped. The plug 22 is adapted to the connecting groove 21 and is fixed to the connecting groove 21 in the horizontal direction.

[0035] A limiting component 3 is provided on the upper side of the main body 1. The limiting component 3 includes a limiting block 31, which is slidably connected to the main body 1. A limiting groove 32 is formed on the main body 1. A plate 33 extends from one side of the limiting block 31 and is inserted into the limiting groove 32. The plate 33 is a thin plate and can deform. The limiting groove 32 has space for the plate 33 to deform. The upper surface of the plate 33 contacts the top wall of the limiting groove 32, and the lower surface of the plate 33 contacts the bottom wall of the limiting groove 32. The plate 33 is inserted into the limiting groove 32, so that the two main bodies 1 are fixed in the longitudinal direction. The horizontal and vertical fixing effectively prevents the hydraulic lock from loosening or shifting due to vibration and other factors during the operation of the hydraulic system, thus ensuring the safety and reliability of the hydraulic equipment.

[0036] The limiting block 31 and the insert block 22 are located on the same side of the main body 1. The limiting groove 32 and the connecting groove 21 are located on the same side of the main body 1. A sliding rod 34 is fixed on the main body 1. The sliding rod 34 slides in cooperation with the limiting block 31. A limiting part 35 is fixed at the end of the sliding rod 34. A sliding groove for the limiting part 35 to enter is opened on the limiting block 31.

[0037] The top surface of the limiting block 31 has multiple anti-slip protrusions 36, which facilitate the movement of the limiting block 31. Mounting plates 4 are provided on both the top and bottom of the main body 1. The mounting plates 4 are fixed to the main body 1 by bolts. Mounting holes 41 are provided on the mounting plates 4, allowing the main body 1 to be fixed in place using bolts and mounting holes 41. The upper mounting plate 4 is positioned to the right, and the lower mounting hole 41 is positioned to the left, facilitating the passage of bolts through the mounting holes 41.

[0038] The side wall of the limiting groove 32 is fixedly connected with a protrusion 37. The plate 33 has a groove 38 on the side facing the anti-slip protrusion 36. The end of the plate 33 has a guide surface. The sliding limiting block 31 causes the plate 33 to move until the protrusion 37 is stuck in the groove 38, so that the limiting block 31 remains stable and prevents the plate 33 from moving laterally and falling off. The assembled hydraulic lock can be reinforced by bolts to the mounting plate 4 at every other point. Of course, the reinforcement location can also be determined by the user.

[0039] If a particular body 1 needs to be removed for maintenance, simply slide the limiting blocks 31 on both sides of body 1 to separate the plate 33 from the anti-slip protrusion 36 until the plate 33 moves into the range of its respective body 1. Then, release the limiting blocks 31, keeping them stationary. Next, remove the bolts on the mounting holes 41. At this point, one of the body 1s can be removed by moving it up or down directly. This eliminates the need for large-scale disassembly of the entire hydraulic lock assembly, significantly reducing maintenance difficulty and workload, and improving equipment maintenance efficiency.

[0040] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
