Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic jack technology, and in particular to a rotary hydraulic jack. Background Technology
[0002] In existing hydraulic jacks, once an object is lifted, it is fixed to the ground by the object's weight, making it impossible to adjust the working angle. While this fixed design meets basic needs in general use, it may not be suitable for adjusting the working angle in certain special applications. For example, in situations requiring rotation or adjustment of the working position, existing hydraulic jacks are not flexible enough. Because the contact point between the hydraulic jack and the object is affected by gravity, once the object is lifted, its position and angle cannot be changed. This makes it difficult for hydraulic jacks to meet the needs of rotation or angle adjustment in some confined or complex workspaces. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies. In conventional hydraulic jacks, after lifting an object, the jack is typically fixed to the ground by the object's weight, preventing adjustment of its working angle. While this fixed design meets basic needs in general use, it may not be suitable for adjusting the working angle in certain special applications. For example, in situations requiring rotation or adjustment of the working position, existing hydraulic jacks are not flexible enough. Because the contact point between the jack and the object is affected by gravity, once the object is lifted, its position and angle cannot be changed. This makes it difficult for hydraulic jacks to meet the needs of rotation or angle adjustment in confined or complex workspaces. Therefore, this invention provides a rotary hydraulic jack.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rotary hydraulic jack, comprising a base, a hydraulic pipe fixedly installed on the top of the base, a piston rod slidably connected to the inner wall of the hydraulic pipe, a control mechanism provided on the top of the base, and a rotating mechanism provided on the bottom of the base and the top of the piston rod. The rotating mechanism includes two support plates, one side of which is fixedly connected to the bottom of the base, and the bottom of the other support plate is fixedly connected to the top of the piston rod. A shaft is fixedly connected to one side of the support plate, and a support shell is rotatably connected to one end of the shaft.
[0005] In a preferred embodiment, a rotating plate is fixedly sleeved on the outer surface of the shaft, and the outer surface of the rotating plate has multiple slots.
[0006] In a preferred embodiment, a card plate is slidably connected to the inner wall of the card slot, and a groove is formed on the inner wall of the support shell, with the inner wall of the groove slidably connected to the outer surface of the card plate.
[0007] In a preferred embodiment, the inner wall of the groove is provided with a support hole, and a support rod is provided on the inner wall of the support hole. One end of the support rod is fixedly connected to one side of the card plate.
[0008] In a preferred embodiment, a handle is fixedly connected to one end of the support rod, and a rotating groove is provided on one side of the handle, with a rotating ring rotatably connected to the inner wall of the rotating groove.
[0009] In a preferred embodiment, a spring is provided on the outer surface of the support rod, one end of the spring is fixedly connected to the outer surface of the support shell, and the other end of the spring is fixedly connected to one side of the swivel.
[0010] In a preferred embodiment, the outer surface of the support rod is provided with a first positioning groove, and the outer surface of the support shell is provided with a second positioning groove.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] This invention uses a control mechanism to control the piston rod's up-and-down movement. The support shells, via a shaft and support plates, allow the structure between the two support plates to rotate simultaneously. After the control mechanism lifts the object by controlling the piston rod, the two support shells contact the object and the ground respectively. The friction between the object / ground and the two support shells prevents them from rotating, while the support plates connected by the shaft can rotate. This rotation control mechanism then drives the base to rotate. The base's rotation, via hydraulic pipes and the piston rod, drives the top support plate to rotate, which in turn drives the bottom support plate to rotate, allowing for position adjustment. The groove allows for... The mechanism allows the card plate to enter, and when the rotating plate rotates, the outermost side pushes the card plate into the groove, preventing interference with the rotation of the rotating plate. When the card plate is in the slot, the support rod can drive the card plate to rotate. After rotating 90 degrees, the card plate can slide into the slot, thus fixing the rotating plate and preventing it from rotating. A spring, through a rotating ring, applies a force to the handle towards the rotating plate, causing the card plate to automatically enter the slot. The rotating ring prevents the spring from failing to rotate, which would affect the handle's ability to drive the support rod. The first positioning groove and two second positioning grooves work together to position the angle of the handle's rotation. Attached Figure Description

[0020] 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.
[0021] Example 1
[0022] like Figure 1-4 As shown, this utility model provides a technical solution: a rotary hydraulic jack, including a base 1, a hydraulic pipe 3 fixedly installed on the top of the base 1, a piston rod 4 slidably connected to the inner wall of the hydraulic pipe 3, a control mechanism 5 provided on the top of the base 1, and a rotating mechanism 2 provided on the bottom of the base 1 and the top of the piston rod 4. The rotating mechanism 2 includes two support plates 21, one side of which is fixedly connected to the bottom of the base 1, and the bottom of the other support plate 21 is fixedly connected to the top of the piston rod 4. A shaft 23 is fixedly connected to one side of the support plate 21, and a support shell 22 is rotatably connected to one end of the shaft 23.
[0023] Through the above embodiments, the control mechanism 5 can control the piston rod 4 to move up and down. The support shell 22, through the cooperation of the shaft 23 and the support plate 21, can make the structure between the two support plates 21 rotate simultaneously. After the control mechanism 5 controls the piston rod 4 to drive the support plate 21 to lift the object, the two support shells 22 contact the object and the ground respectively. Thus, through the friction between the object, the ground and the two support shells 22, the two support shells 22 cannot rotate, while the support plate 21, which is rotatably connected by the shaft 23, can rotate. Then, the rotation control mechanism 5 can drive the base 1 to rotate. The rotation of the base 1 can drive the top support plate 21 to rotate through the hydraulic pipe 3 and the piston rod 4. The rotation of the base 1 can drive the bottom support plate 21 to rotate, thereby adjusting the position.
[0024] A rotating plate 24 is fixedly sleeved on the outer surface of the shaft 23, and multiple slots 25 are opened on the outer surface of the rotating plate 24.
[0025] The inner wall of the slot 25 is slidably connected to the card plate 26, and the inner wall of the support shell 22 is provided with a groove 27, the inner wall of the groove 27 being slidably connected to the outer surface of the card plate 26.
[0026] Through the above embodiments, the outer wall of the card slot 25 is curved, which can cooperate with the side wall of the card plate 26;
[0027] The inner wall of the groove 27 is provided with a support hole 28, and a support rod 29 is provided on the inner wall of the support hole 28. One end of the support rod 29 is fixedly connected to one side of the clamping plate 26.
[0028] Through the above embodiments, the groove 27 allows the clamping plate 26 to enter, and when the rotating plate 24 rotates, the outermost side can push the clamping plate 26 into the interior of the groove 27, thus avoiding affecting the rotation of the rotating plate 24. When the clamping plate 26 is located in the slot 25, the support rod 29 can drive the clamping plate 26 to rotate. After the clamping plate 26 rotates ninety degrees, it can slide into the interior of the slot 25, thereby fixing the rotating plate 24 through the clamping plate 26 and the support rod 29, thus preventing the rotating plate 24 from rotating.
[0029] One end of the support rod 29 is fixedly connected to a handle 210. A rotating groove is provided on one side of the handle 210, and a rotating ring 212 is rotatably connected to the inner wall of the rotating groove.
[0030] A spring 211 is provided on the outer surface of the support rod 29. One end of the spring 211 is fixedly connected to the outer surface of the support shell 22, and the other end of the spring 211 is fixedly connected to one side of the swivel ring 212.
[0031] Through the above embodiments, the spring 211, through the rotating ring 212, gives the handle 210 a force toward the rotating plate 24, thereby enabling the locking plate 26 to automatically enter the slot 25. The rotating ring 212 can prevent the spring 211 from being unable to rotate, thus affecting the handle 210's ability to rotate the support rod 29.
[0032] The outer surface of the support rod 29 is provided with a first positioning groove 213, and the outer surface of the support shell 22 is provided with a second positioning groove 214;
[0033] In the above embodiments, the first positioning groove 213 and the two second positioning grooves 214 cooperate to position the angle of rotation of the handle 210.
[0034] Working principle:
[0035] like Figure 1-4 As shown, during use, when rotation is required, the handle 210 drives the support rod 29 to move, and the movement of the support rod 29 drives the locking plate 26 to move. After the locking plate 26 contacts the inner wall of the support shell 22, the handle 210 drives the support rod 29 to rotate, and the rotation of the support rod 29 drives the locking plate 26 to rotate. Rotation can be stopped by observing that the first positioning groove 213 is aligned with the vertical second positioning groove 214. At this time, the locking plate 26 separates from the locking groove 25. After the control mechanism 5 controls the piston rod 4 to drive the support plate 21 to lift the object, the two support shells 22 contact the object and the ground respectively. Thus, through the friction between the object, the ground and the two support shells 22, the two support shells 22 cannot rotate. The support plate connected by the shaft 23 rotates. 21 can rotate, and then the rotation control mechanism 5 can drive the base 1 to rotate. The rotation of the base 1 can drive the top support plate 21 to rotate through the hydraulic pipe 3 and the piston rod 4. The rotation of the base 1 can drive the bottom support plate 21 to rotate, so that the position can be adjusted. After the adjustment is completed, check whether the first positioning groove 213 is aligned with the outer surface of the support shell 22. If it is not aligned, fine adjust the control mechanism 5 to make it aligned. If it is aligned, control the handle 210 to drive the support rod 29 to rotate. When the first positioning groove 213 on the support rod 29 is aligned with the horizontal second positioning groove 214, the handle 210 can be released. At this time, under the action of the spring 211, the locking plate 26 can be driven into the interior of the locking groove 25.
[0036] 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.
