Description

Technical Field

[0001] This utility model relates to the field of hydraulic power technology, and in particular to a telescopic device for a hydraulic power mechanism. Background Technology

[0002] Hydraulic power mechanisms are now widely available on the market. The telescopic devices of hydraulic power mechanisms mainly rely on the combined action of hydraulic cylinders and piston rods to achieve the extension and retraction of the piston rod. However, due to the unstable nature of hydraulic power, the piston rod linkage, i.e., synchronous action, is rarely found on the market.

[0003] Existing hydraulic power mechanism telescopic devices suffer from left-right and front-back swaying during extension and retraction, affecting their use. Furthermore, the inability to lock the device during extension and retraction makes operation and use inconvenient. Therefore, this invention proposes a hydraulic power mechanism telescopic device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of left-right and front-back swaying during the extension and retraction of existing hydraulic power mechanism telescopic devices, which affects their use. At the same time, the hydraulic power mechanism telescopic device cannot be positioned and locked during extension and retraction, which makes operation and use inconvenient. Therefore, a hydraulic power mechanism telescopic device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hydraulic power mechanism telescopic device, comprising

[0007] Hydraulic rod;

[0008] The mounting brackets are of two types, and the two mounting brackets are fixedly installed on the left and right sides of the hydraulic rod, respectively;

[0009] The support frame has its top fixedly sleeved on the output shaft at the top of the hydraulic rod, and the two support frames are slidably connected to the left and right sides of the two mounting frames respectively on the side that is close to each other.

[0010] The system includes an unlocking mechanism and a positioning mechanism, each in two sets, with the unlocking mechanism cooperating with the mounting bracket and the positioning mechanism respectively.

[0011] The support mechanism consists of four sets, and includes: a blocking frame, a blocking spring, and a spring seat;

[0012] The blocking frame is slidably connected to the mounting frame. The blocking frame cooperates with the support frame. The blocking frame is fixedly connected to the blocking spring. The blocking spring is fixedly connected to the spring seat. The spring seat is fixedly connected to the mounting frame.

[0013] As a preferred embodiment of this utility model, the unlocking mechanism includes: two fixing frames and an unlocking frame;

[0014] Two fixed brackets are fixedly connected to the front of two adjacent blocking brackets respectively, and the unlocking bracket is slidably connected to the front of the mounting bracket, with the unlocking bracket cooperating with the fixed bracket.

[0015] As a preferred embodiment of this utility model, the positioning mechanism includes: a fixing plate, a positioning frame, a positioning spring, a fixing block, and an unlocking rod;

[0016] The fixing block is fixedly installed on the front side of the mounting frame, the positioning frame is slidably connected to the front side of the unlocking frame, the positioning frame is fixedly connected to the positioning spring, the positioning spring is fixedly connected to the fixing block, the fixing block is fixedly connected to the unlocking frame, and the unlocking rod is fixedly connected to the positioning frame.

[0017] As a preferred embodiment of this utility model, the fixing plate is provided with symmetrically arranged positioning grooves, and a positioning block is fixedly installed on the positioning frame. The positioning block and the positioning groove can be detachably snapped together.

[0018] As a preferred embodiment of this utility model, symmetrically arranged circular blocks are fixedly installed on the front side of the unlocking frame, and the two circular blocks are slidably connected to the inner sides of the two fixed frames respectively.

[0019] As a preferred embodiment of this utility model, the support frame has multiple equally spaced blocking grooves on its left, right, front and rear sides, and the blocking frame is fixedly installed with blocking blocks, which can be detachably engaged with the inner wall of the blocking groove.

[0020] Beneficial effects:

[0021] 1. After the unlocking frame is pressed down, the unlocking frame can drive the two round blocks to descend, so that the two round blocks slide vertically downward on the inside of the fixed frame. This allows the two round blocks to push the two fixed frames away from each other, and the two fixed frames can then drive the two blocking frames at the current position to disengage from the support frame. This allows the support frame on one side to be unlocked. Both sides of the support frame use the same unlocking method, so that the support frame can extend and retract with the hydraulic rod, which facilitates the support of the hydraulic rod.

[0022] 2. After the positioning frame engages with the fixed plate, the positioning frame can connect the fixed plate and the unlocking frame to block the movement of the unlocking frame on the fixed plate. This allows the unlocking frame to position the two fixed frames. Positioning the unlocking frame at the top position allows the two blocking frames to be stably attached to the support frame. When the unlocking frame is positioned at the bottom position, it will continuously push the fixed frame and the blocking frame apart. The blocking frame can continuously disengage from the support frame and continuously unlock, making it convenient to use the support frame.

[0023] In this invention, the support frame and the mounting frame are slidably connected, so that the support frame can stably support the hydraulic rod on the mounting frame, which greatly reduces the problem of the hydraulic rod swaying left and right and back and forth. In addition, the position of the support frame on the mounting frame can be fixed, so that the support frame can position and lock the hydraulic rod, which is convenient for use.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example

[0031] Reference Figures 1-4 A hydraulic power mechanism telescopic device, comprising

[0032] Hydraulic rod 1;

[0033] Mounting bracket 3, there are two mounting brackets 3, and the two mounting brackets 3 are fixedly installed on the left and right sides of the hydraulic rod 1 respectively;

[0034] Support frame 2, the top of support frame 2 is fixedly sleeved on the output shaft at the top of hydraulic rod 1, and the two support frames 2 are slidably connected to the left and right sides of the two mounting frames 3 respectively on the side that is close to each other;

[0035] There are two sets of unlocking and positioning mechanisms. The unlocking mechanism is used in conjunction with the mounting bracket 3 and the positioning mechanism, respectively.

[0036] The support mechanism consists of four sets, including: a blocking frame 4, a blocking spring 5, and a spring seat 6.

[0037] The blocking frame 4 is slidably connected to the mounting frame 3. The blocking frame 4 cooperates with the support frame 2. The blocking frame 4 is fixedly connected to the blocking spring 5. The blocking spring 5 is fixedly connected to the spring seat 6. The spring seat 6 is fixedly connected to the mounting frame 3.

[0038] With the above structure, the support frame 2 can stably support the hydraulic rod 1 on the mounting frame 3 through the sliding connection between the support frame 2 and the mounting frame 3, which greatly reduces the problem of the hydraulic rod 1 swaying left and right and back and forth. In addition, the position of the support frame 2 on the mounting frame 3 can also be positioned, so that the support frame 2 can position and lock the hydraulic rod 1 for convenient use.

[0039] As a preferred embodiment of this utility model, the unlocking mechanism includes: two fixing frames 7 and an unlocking frame 8;

[0040] Two fixed frames 7 are fixedly connected to the front of two adjacent blocking frames 4 respectively. The unlocking frame 8 is slidably connected to the front of the mounting frame 3. The unlocking frame 8 cooperates with the fixed frame 7. After the unlocking frame 8 is pressed down, the unlocking frame 8 can drive the two round blocks to descend, so that the two round blocks slide vertically downward inside the fixed frame 7, so that the two round blocks can squeeze the two fixed frames 7 away from each other. The two fixed frames 7 can then drive the two blocking frames 4 at the current position to disengage from the support frame 2, so that the support frame 2 at one side can be unlocked. The same unlocking method is used on both sides of the support frame 2, so that the support frame 2 can extend and retract with the hydraulic rod 1, which facilitates the support of the hydraulic rod 1.

[0041] As a preferred embodiment of this utility model, the positioning mechanism includes: a fixing plate 9, a positioning frame 10, a positioning spring 11, a fixing block 12, and an unlocking rod 13;

[0042] The fixing block 12 is fixedly installed on the front side of the mounting bracket 3. The positioning bracket 10 is slidably connected to the front side of the unlocking bracket 8. The positioning bracket 10 is fixedly connected to the positioning spring 11, the positioning spring 11 is fixedly connected to the fixing block 12, the fixing block 12 is fixedly connected to the unlocking bracket 8, and the unlocking rod 13 is fixedly connected to the positioning bracket 10. After the positioning bracket 10 engages with the fixing plate 9, the positioning bracket 10 can connect the fixing plate 9 and the unlocking bracket 8 to block the movement of the unlocking bracket 8 on the fixing plate 9, so that the unlocking bracket 8 can position the two fixing brackets 7. Positioning the unlocking bracket 8 at the upper position allows the unlocking bracket 8 to position the two fixing brackets 7, so that the two blocking brackets 4 can stably fit against the support bracket 2. When the unlocking bracket 8 is positioned at the lower position, it will continuously open the fixing brackets 7 and the blocking brackets 4. The blocking brackets 4 can continuously disengage from the support bracket 2 and continuously unlock, making it convenient to use the support bracket 2.

[0043] As a preferred embodiment of this utility model, the fixing plate 9 is provided with symmetrically arranged positioning grooves, and the positioning frame 10 is fixedly installed with positioning blocks. The positioning blocks and positioning grooves can be detachably snapped together. When the positioning blocks are inserted into the inner side of the positioning grooves, the positioning blocks can block the movement of the unlocking frame 8, thereby achieving the positioning of the unlocking frame 8.

[0044] As a preferred embodiment of this utility model, symmetrically arranged circular blocks are fixedly installed on the front side of the unlocking frame 8. The two circular blocks are slidably connected to the inner sides of the two fixed frames 7 respectively. The circular blocks are used to connect the unlocking frame 8 and the fixed frames 7, so that the unlocking frame 8 can drive the fixed frames 7 away from each other when it moves.

[0045] As a preferred embodiment of this utility model, the support frame 2 has multiple blocking grooves arranged at equal intervals on its left, right, front and rear sides. The blocking frame 4 is fixedly installed with blocking blocks. The blocking blocks can be disengaged from the inner wall of the blocking grooves. When the blocking grooves engage with the support frame 2, the blocking frame 4 can continuously block the movement of the support frame 2, so that the support frame 2 can continuously support the hydraulic rod 1.

[0046] The working principle of this utility model is as follows: When the hydraulic rod 1 needs to be used, first pull the unlocking rod 13 to move it, so that the unlocking rod 13 can drive the positioning frame 10 to disengage from the fixed plate 9, unlocking the unlocking frame 8. Then, press the unlocking frame 8 down. After the unlocking frame 8 is pressed down, the unlocking frame 8 can drive the two round blocks to descend, so that the two round blocks slide vertically downward on the inner side of the fixed frame 7, so that the two round blocks can squeeze the two fixed frames 7 away from each other. The two fixed frames 7 can then drive the two blocking frames 4 at the current position to disengage from the support frame 2, thus unlocking the support frame 2 at one side. Both sides of the support frame 2 adopt the same unlocking method, so that the support frame 2 can extend and retract with the hydraulic rod 1, which is convenient for supporting the hydraulic rod 1. At this time, release the positioning frame 10, so that the positioning frame 10 can automatically engage with the fixed rod. After the positioning frame 10 engages with the fixed plate 9, the positioning frame 10 can connect the fixed plate 9 and the unlocking frame 8 to block the movement of the unlocking frame 8 on the fixed plate 9, so that the unlocking frame 8 can unlock the position of the two fixed frames 7. Positioning is performed so that when the unlocking frame 8 is positioned in the lower position, it continuously expands the fixed frame 7 and the blocking frame 4. The blocking frame 4 can continuously disengage from the support frame 2, continuously unlocking, facilitating the use of the support frame 2. Through the sliding connection between the support frame 2 and the mounting frame 3, the support frame 2 can stably support the hydraulic rod 1 on the mounting frame 3, greatly reducing the problem of the hydraulic rod 1 swaying left and right and back and forth. Then, the unlocking frame 8 is unlocked again and released, so that the unlocking frame 8 can release the two blocking frames 4, allowing the two blocking frames 4 to reset and engage with the support frame 2. Then, the unlocking frame 8 is positioned above the fixed plate 9. Positioning the unlocking frame 8 in the upper position allows the unlocking frame 8 to position the two fixed frames 7, so that the two blocking frames 4 can stably fit against the support frame 2. When the blocking groove engages with the support frame 2, the blocking frame 4 can continuously prevent the support frame 2 from moving, allowing the support frame 2 to continuously support the hydraulic rod 1, positioning and locking the hydraulic rod 1 for convenient use.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
