Description

Technical Field

[0001] This utility model relates to the field of bidirectional hydraulic jacks, and in particular to a bidirectional hydraulic jack. Background Technology

[0002] A two-way hydraulic jack is a lifting device that uses the bidirectional flow of hydraulic oil to achieve lifting and retraction. It is widely used in automotive repair, building support, and industrial equipment installation. Unlike unidirectional hydraulic jacks, two-way jacks actively control lifting and lowering via a hydraulic system, resulting in more efficient and precise operation.

[0003] Existing two-way hydraulic jacks require connection to hydraulic hoses to transmit pressure. These hoses are typically connected to the jack using a threaded ring. However, this threaded ring lacks an anti-reverse component, allowing it to rotate and become unstable, resulting in an inconvenient connection between the hydraulic hoses and the jack. Therefore, we offer a new type of two-way hydraulic jack. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing bidirectional hydraulic jacks in terms of insufficient stability when connected to hydraulic oil pipes, and to provide a bidirectional hydraulic jack.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bidirectional hydraulic jack, comprising: a jack body, a fixing mechanism on one side of the jack body, the fixing mechanism including a push ring, the push ring being sleeved on the outer surface of the jack body, a spring on one side of the push ring, a conical block on one side of the push ring, the conical block being fixedly connected to the push ring, a fixing rod on one side of the conical block, a sleeve block sleeved on the outer surface of the fixing rod, the sleeve block being slidably connected to the fixing rod, a spring on the outer surface of the fixing rod, an inclined block fixedly connected to one side of the sleeve block, a locking block fixedly connected to one side of the sleeve block, a limit plate fixedly connected to one end of the fixing rod, and a connecting mechanism on one side of the push ring.

[0006] In a preferred embodiment, the push ring is slidably connected to the jack body, the spring is sleeved on the outer surface of the jack body, and the fixing rod is fixedly connected to the jack body.

[0007] In a preferred embodiment, the sleeve block is slidably connected to the fixed rod, and the two ends of the second spring are respectively fixedly connected to the outer surfaces of the sleeve block and the limiting plate.

[0008] In a preferred embodiment, the connecting mechanism includes a hydraulic hose, which is sleeved inside the jack body and slidably connected to the jack body.

[0009] In a preferred embodiment, a retaining ring is fitted onto the outer surface of the hydraulic oil pipe, the retaining ring is fixedly connected to the hydraulic oil pipe, and an annular groove is formed on the retaining ring.

[0010] In a preferred embodiment, an O-ring is provided in the mounting groove on the hydraulic oil pipe, and the O-ring is slidably connected to the hydraulic oil pipe.

[0011] In a preferred embodiment, the two ends of the spring are fixedly connected to the outer surfaces of the push ring and the jack body, respectively.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention, through the setting of a fixing mechanism, prevents the connecting mechanism from detaching from the jack body after insertion. A fixing block is provided that engages with the annular groove on the fixing ring, preventing the fixing ring from sliding under the action of multiple fixing blocks. A second spring is also provided, applying pressure to the sleeve block, ensuring the fixing block, which is fixedly connected to the sleeve block, is securely placed inside the fixing ring. Furthermore, a conical block is provided, which can cooperate with an inclined block, allowing the height of the inclined block to be adjusted.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Example 1

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a bidirectional hydraulic jack, comprising: a jack body 1, a fixing mechanism 2 on one side of the jack body 1, the fixing mechanism 2 including a push ring 21, the push ring 21 being sleeved on the outer surface of the jack body 1, a spring 22 on one side of the push ring 21, a conical block 23 on one side of the push ring 21, the conical block 23 being fixedly connected to the push ring 21, a fixing rod 24 on one side of the conical block 23, a sleeve block 25 sleeved on the outer surface of the fixing rod 24, and the sleeve block 25 being connected to the fixing rod 24. The sliding connection includes a spring 26 fitted onto the outer surface of the fixed rod 24, a bevel block 27 fixedly connected to one side of the sleeve block 25, a locking block 28 fixedly connected to one side of the sleeve block 25, a limiting piece 29 fixedly connected to one end of the fixed rod 24, a connecting mechanism 3 provided on one side of the push ring 21, the push ring 21 being slidably connected to the jack body 1, a spring 22 fitted onto the outer surface of the jack body 1, the fixed rod 24 being fixedly connected to the jack body 1, and the two ends of the spring 26 being fixedly connected to the outer surfaces of the sleeve block 25 and the limiting piece 29, respectively.

[0025] In this embodiment, by setting a push ring 21, the user can drive the conical block 23 through the push ring 21 and pull the spring 22. When the conical block 23 slides, it can drive multiple inclined blocks 27, so that the inclined blocks 27 can change their height while sliding in contact with the conical block 23. When the height of the inclined block 27 increases, the locking block 28 will be raised at the same time under the action of the sleeve block 25, so that the position of the locking block 28 will not affect the installation of the hydraulic oil pipe 31 and ensure that the position of the fixing ring 32 is in the proper state. The spring 22 is set, and the spring 22 can generate elastic force after being stretched and deformed. When the push ring 21 is stopped, the elastic force of the spring 22 will be released instantly, so that the push ring 21 and the conical block 23 can automatically reset. Thus, the position of the inclined block 27 can be restored to the initial position, and at this time the locking block 28 can enter the interior of the fixing ring 32, so that the fixing ring 32 will not move after installation.

[0026] Example 2

[0027] like Figures 1-4 As shown, the connecting mechanism 3 includes a hydraulic oil pipe 31, which is sleeved inside the jack body 1 and slidably connected to the jack body 1. A fixing ring 32 is sleeved on the outer surface of the hydraulic oil pipe 31 and is fixedly connected to the hydraulic oil pipe 31. An annular groove 33 is provided on the fixing ring 32. An O-ring seal 34 is provided in the mounting groove on the hydraulic oil pipe 31 and is slidably connected to the hydraulic oil pipe 31.

[0028] In this embodiment, a second spring 26 is provided, and the second spring 26 can generate elastic force after being compressed by the sleeve block 25. The elastic force of the second spring 26 can act on the sleeve block 25 and the locking block 28, so that the locking block 28 can not only be reset into the interior of the fixing ring 32, but also ensure that the locking block 28 is in a stable state. An O-ring 34 is provided, and there are two O-rings 34. The O-rings 34 can be installed in the mounting groove opened on the hydraulic oil pipe 31. Thus, the O-rings 34 can enter the interior of the jack body 1 under the drive of the hydraulic oil pipe 31, and seal the hydraulic oil pipe 31 and the jack body 1 with the O-rings 34.

[0029] Working principle:

[0030] like Figures 1-4As shown, in use, the connecting mechanism 3 needs to be connected to the jack body 1. First, push the push ring 21, which drives the conical block 23 to slide. As the conical block 23 slides, its special shape compresses and drives the inclined block 27, causing the inclined block 27 to slide on the surface of the conical block 23. Simultaneously, the inclined block 27 moves upwards, allowing the sleeve block 25 to slide on the outer surface of the fixed rod 24. At the same time, the push ring 21 stretches and deforms the first spring 22, generating elastic force. Furthermore, the sleeve block 25 compresses the second spring 26 as it slides on the fixed rod 24, also generating elastic force. Then, as the position of the inclined block 27 changes, the position of the locking block 28 changes simultaneously, allowing the hydraulic oil pipe 31 in the connecting mechanism 3 to be installed inside the jack body 1. The installation of the hydraulic oil pipe 3... First, two O-rings 34 need to be installed inside the mounting groove on the hydraulic oil pipe 31. Then, the hydraulic oil pipe 31 drives the O-rings 34 into the jack body 1. At this time, the O-rings 34 will deform under the combined action of the hydraulic oil pipe 31 and the inner wall of the jack body 1. The O-rings 34 can fill the gap between the hydraulic oil pipe 31 and the jack body 1, so that the hydraulic oil pipe 31 is sealed. Then, the push ring 21 is released. At this time, the elastic force of the first spring 22 will be released instantly, and the push ring 21 and the conical block 23 will be pulled back to their original positions. As the conical block 23 is reset, the elastic force of the second spring 26 will be released instantly, and the sleeve block 25, the inclined block 27 and the locking block 28 will be reset. The multiple locking blocks 28 will engage inside the annular groove 33 on the fixing ring 32, and limit the fixing ring 32, so that the hydraulic oil pipe 31 remains stable after installation.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
