DETAILED DESCRIPTION
[0021] The utility model can be explained in detail through the following examples, the purpose of the utility model is to protect all technical improvements in the scope of the utility model, in the description of the utility model, it needs to be understood that if the orientation or position relation indicated by the terms "upper", "lower", "front", "rear", "left", "right" and the like, only corresponds to the drawing of the application, in order to facilitate the description of the utility model, and not indicate or imply that the indicated device or element must have a particular orientation.
[0022] Please refer to Figures 1-5 The utility model provides the following technical schemes:
[0023] Example 1: a built-in oil circuit's lift device structure, including oil tank 1, telescopic oil cylinder 2, seat body 4 and gear pump 5, oil tank 1 and gear pump 5 are installed on the upper portion both sides of seat body 4, and telescopic oil cylinder 2 is located between oil tank 1 and gear pump 5, the lower portion of seat body 4 is equipped with connecting shaft 3, and ear seat 2.4 of telescopic oil cylinder 2 is gap fit with connecting shaft 3.
[0024] Telescopic oil cylinder 2 has oil inlet channel 2.3 and oil outlet channel 2.2, and one end of oil inlet channel 2.3 and oil outlet channel 2.2 is communicated with the inner cavity of ear seat 2.4, and the other end of oil inlet channel 2.3 and oil outlet channel 2.2 is communicated with the both ends of cylinder body 2.1 of telescopic oil cylinder 2 respectively.
[0025] Seat body 4 is equipped with oil return channel 4.2 communicated with oil tank 1, and connecting shaft 3 is equipped with flow channel one 3.1 communicated with oil return channel 4.2 and oil outlet channel 2.2.
[0026] Seat body 4 is equipped with oil supply channel 4.1 communicated with gear pump 5, and connecting shaft 3 is equipped with flow channel two 3.2 communicated with oil supply channel 4.1 and oil inlet channel 2.3.
[0027] Seat body 4 is further equipped with channel 4.3 communicated with oil tank 1 and gear pump 5.
[0028] It is understandable that the gear pump 5 supplies oil to the telescopic cylinder 2 through the oil supply channel 4.1, the flow channel 2 3.2, and the oil inlet channel 2.3. Under the action of oil pressure, the piston rod inside the telescopic cylinder 2 moves upward, and the telescopic cylinder 2 extends. The oil inside the telescopic cylinder 2 enters the oil tank 1 through the oil outlet channel 2.2, the flow channel 1 3.1, and the oil return channel 4.2, and then returns to the gear pump 5 through the channel 4.3, realizing oil circulation. When the gear pump 5 reverses, the telescopic cylinder 2 retracts, and the above process is reversed. By using the built-in oil circuit, the traditional external oil pipe connection method is eliminated, which solves the problem of oil leakage caused by bumps and knocks of the traditional external oil pipe, resulting in shutdown and inability to operate normally. This improves the safety performance of the equipment and ensures safe use.
[0029] Example 2: Unlike Example 1, the ear seat 2.4 is provided with an annular groove 2.41 that communicates with the oil outlet channel 2.2, and the ear seat 2.4 is provided with an annular groove 2.42 that communicates with the oil inlet channel 2.3.
[0030] like Figure 5 As shown, flow channel 3.1 includes an axial blind hole, the opening of which is sealed. The axial blind hole connects to radial through hole one and radial through hole two. Radial through hole one is connected to an annular groove one 2.41, and radial through hole two is connected to the oil return channel 4.2. Flow channel 3.2 includes an axial blind hole, the opening of which is sealed. The axial blind hole connects to radial through hole one and radial through hole two. Radial through hole one is connected to an annular groove two 2.42, and radial through hole two is connected to the oil supply channel 4.1. Corresponding connection; that is, when the lug 2.4 rotates around the connecting shaft 3, the oil circuit can also circulate normally. For example, when the gear pump 5 supplies oil, the high-pressure oil enters the radial through hole 2 in the flow channel 3.2 through the oil supply channel 4.1, and then flows to the radial through hole 2 through the axial blind hole. Subsequently, it enters the telescopic cylinder 2 through the annular groove 2.42 and the oil supply channel 4.1. Similarly, the oil enters the oil tank 1 through the oil outlet channel 2.2, the flow channel 3.1 and the return channel 4.2.
[0031] In addition, the gear pump 5 integrates a motor, which drives the gear pump 5 in both directions.
[0032] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents in the content of this utility model.
