DETAILED DESCRIPTION

[0018] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0019] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0020] The automobile steering gear transfer platform provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0021] Example 1: An embodiment of the present application provides a car steering gear transfer platform, including a platform 1 and a plurality of clamps 2, which are symmetrically distributed in two rows on the platform 1, and the clamps 2 include an inner tube 21, an outer tube 22, a lifting sleeve 23, an annular cavity 24 and two pairs of clamps 25; the inner tube 21 and the outer tube 22 are both fixedly mounted on the top surface of the platform 1, and the annular cavity 24 is formed between the outer ring of the inner tube 21 and the inner ring of the outer tube 22; the lifting sleeve 23 can be lifted and lowered along the inner tube 21, and the clamps 25 are rotatably sleeved on the outer ring of the lifting sleeve 23 and establish a transmission connection with the inner ring of the outer tube 22, and a clamping groove 26 is provided on the top of the clamps 25; when the lifting sleeve 23 rises or falls, each pair of clamps 25 performs a lifting action synchronously, and the corresponding pair of clamps 25 are separated or closed from each other, thereby achieving the clamping and release of the car steering gear.

[0022] like Figure 1 and Figure 4As shown, due to the adoption of the above-mentioned structure, when the automobile steering gear needs to be transported, the end of the automobile steering gear is placed on the top of the lifting sleeve 23, and the operator acts on the automobile steering gear through external force to transmit the external force to the lifting sleeve 23, causing it to move downward along the inner tube 21. During the descending process of the lifting sleeve 23, the splint 25 that establishes a transmission connection with the inner ring of the outer tube 22 will synchronously perform the lifting action based on the transmission relationship. At the same time, as the lifting sleeve 23 descends, the splints 25 will close together due to the characteristics of the transmission connection, and clamp and fix the steering gear through the clamping groove, thereby realizing stable transportation of the automobile steering gear. This structural design makes the operation of the transfer platform more intuitive, and the clamping of the steering gear can be completed by a simple operation of the lifting sleeve 23, which effectively improves the transportation efficiency.

[0023] Example 2: The difference from Example 1 is that, in this embodiment, in addition to the structural features of the aforementioned embodiment, the clamp 2 also includes a rotating ring groove 27 and a rotating slider. The rotating ring groove 27 is opened on the outer peripheral wall of the lifting sleeve 23, and the rotating slider is slidably installed in the rotating ring groove 27 and fixed on the inner wall of the clamp 25.

[0024] In this embodiment of the present application, there is a pair of rotating ring grooves 27 , the number of rotating sliders corresponds to the number of rotating ring grooves 27 , and each rotating ring groove 27 is slidably matched with each rotating slider one by one.

[0025] like Figure 4 As shown, due to the adoption of the above-mentioned structure, when the lifting sleeve 23 drives the splint 25 to perform lifting and rotating movements, the rotating slider slides in the rotating ring groove 27. The cooperation between the rotating ring groove 27 and the rotating slider, on the one hand, limits the rotation direction of the splint 25, ensures its rotation stability, and avoids the splint 25 from deflecting or shaking during the rotation process; on the other hand, in the process of the splint 25 rotating to separate or close each other, the sliding of the rotating slider in the rotating ring groove 27 plays a guiding and supporting role, making the rotation of the splint 25 smoother, further improving the reliability of the splint 25 clamping the automobile steering gear, and even if encountering bumps and the like during transportation, it can ensure that the splint 25 stably clamps the steering gear, reducing the possibility of steering gear shaking.

[0026] Example 3: The difference from Example 2 is that, in addition to the structural features of the aforementioned embodiments, spiral grooves 28 corresponding to the number of splints 25 are provided on the inner circumferential wall of the outer tube 22, and each splint 25 is fixed with a transmission slider that slides with the corresponding spiral groove 28. Through the cooperation between the transmission slider and the spiral groove 28, when the lifting sleeve 23 is lifted and lowered along the inner tube 21, the transmission slider slides along the track of the spiral groove 28, driving the splints 25 to rotate around the lifting sleeve 23, thereby realizing the synchronous separation or closing action of the splints 25.

[0027] like Figures 4 and 5 As shown, due to the adoption of the above-mentioned structure, when the lifting sleeve 23 is lifted and lowered along the inner tube 21, the transmission slider on the splint 25 will slide along the track of the spiral groove 28 on the inner circumferential wall of the outer tube 22. As the transmission slider slides in the spiral groove 28, the splint 25 is driven to rotate around the lifting sleeve 23, thereby realizing the synchronous separation or closing action of the splint 25. This transmission method based on the spiral groove 28 and the transmission slider converts the linear lifting motion of the lifting sleeve 23 into the rotational motion of the splint 25, and can accurately control the opening and closing degree of the splint 25.

[0028] When the lifting sleeve 23 rises, the transmission slider rises along the spiral groove 28 and drives the clamping plate 25 to rotate outward and separate; when the lifting sleeve 23 descends, the transmission slider descends along the spiral groove 28 and drives the clamping plate 25 to rotate inward and close. Through this ingenious transmission coordination, the automobile steering gear can be clamped and released quickly and stably without the need for a complicated operating mechanism.

[0029] Example 4: The difference from Example 3 is that, in addition to the structural features of the aforementioned embodiments, the clamp 2 also includes a reset ring groove 29, a reset spring 210, a locking member 3 and an unlocking member 4; the reset ring groove 29 is opened at the top of the inner cavity of the inner tube 21, and the reset spring 210 is installed in the reset ring groove 29, and the top of the reset spring 210 abuts against the top of the inner cavity of the lifting sleeve 23; when the lifting sleeve 23 descends to the top of its inner cavity and contacts the top of the inner tube 21, the locking member 3 is used to fix the lifting sleeve 23; the unlocking member 4 is used to release the lock member 3 from the fixation of the lifting sleeve 23, so that the lifting sleeve 23 can be released from the fixed state.

[0030] like Figure 4 As shown, due to the adoption of the above-mentioned structure, when the lifting sleeve 23 descends to the top of its inner cavity and contacts the top of the inner tube 21, the return spring 210 is in a compressed state, providing an upward return tendency for the lifting sleeve 23, and the insert block 31 in the locking member 3 will automatically insert into the slot 32 on the inner wall of the lifting sleeve 23 under the action of the preload spring 33, firmly fixing the lifting sleeve 23 on the inner tube 21, preventing the lifting sleeve 23 from accidentally rising during transportation, and ensuring that the automobile steering gear is stably clamped. When the steering gear needs to be released, the locking member 3 is used to release the fixing of the lifting sleeve 23. The setting of the unlocking member 4 enables the operator to conveniently control the fixing and unlocking states of the lifting sleeve 23, while ensuring the stability of transportation, it also facilitates the loading and unloading operations of the steering gear, making the transportation process safer and more efficient.

[0031] Example 5: The difference from Example 4 is that, in addition to the structural features of the aforementioned embodiments, the locking member 3 includes an insert block 31 symmetrically slidably inserted on the side wall of the inner tube 21, and a slot 32 symmetrically arranged on the inner wall of the lifting sleeve 23. A pre-tightening spring 33 is installed between the inner ends of a pair of insert blocks 31, and the outer ends are inclined to form an upward guide surface 34.

[0032] In this embodiment of the present application, the unlocking member 4 includes a fixed column 41 fixed on the top of the inner cavity of the lifting sleeve 23, and a rotating sleeve 42 rotatably installed at the bottom of the fixed column 41. The lower end of the rotating sleeve 42 is fixed with an unlocking lever 43, and a lifting groove 44 symmetrically provided on the side wall for sliding cooperation with the insertion block 31. The top of the lifting groove 44 is provided with an unlocking lever block 45, and the top surface of the insertion block 31 is provided with a triangular lever groove 46 for transmission with the unlocking lever block 45.

[0033] In this embodiment of the present application, the unlocking member 4 also includes a lifting groove 47 symmetrically arranged on the inner wall of the inner tube 21, a reset groove 48 arranged at the bottom of the lifting groove 47 and extending circumferentially, and a reset slider 49 symmetrically fixed on the outer wall of the rotating sleeve 42. The top surface of the reset groove 48 is inclined and the higher end is connected to the lifting groove 47. The reset slider 49 can slide in the lifting groove 47 and the reset groove 48.

[0034] like Figures 4 to 8 As shown, due to the adoption of the above-mentioned structure, when locking is required, the lifting sleeve 23 descends, the lower end contacts the guide surface 34 and pushes the pair of plug blocks 31 to retract into the inner tube 21, and the pre-tightening spring 33 is compressed to store elastic potential energy until the slot 32 moves to correspond to the plug block 31, and the pre-tightening spring 33 releases the elastic potential energy to push the outer end of each plug block 31 into the corresponding slot 32, completing the fixation of the lifting sleeve 23. When unlocking is required, the operator uses external force to toggle the unlocking lever 43 to rotate the rotating sleeve 42, and the unlocking lever 45 extends into and cooperates with the triangular groove 46 on the top surface of the plug block 31, pulling and pushing the plug block 31 toward the inner tube 21. The inner cavity moves, causing the insert block 31 to withdraw from the slot 32 of the lifting sleeve 23, thereby releasing the locking piece 3 from the fixation of the lifting sleeve 23, and the reset slider 49 slides to the reset groove 48 and one end of the lifting groove 47. Since the top surface of the reset groove 48 is inclined and connected to the lifting groove 47, after the unlocking operation is completed, the reset slider 49 on the outer wall of the rotating sleeve 42 slides from the higher end of the reset groove 48 into the lifting groove 47 under the action of the reset spring 210, driving the rotating sleeve 42 to automatically reset and prepare for the next unlocking operation. The entire unlocking process is simple to operate, and the various components cooperate closely, which can reliably realize the unlocking and resetting of the lifting sleeve 23.

[0035] A ring groove is provided at the bottom of the fixed column 41, and a ring edge is provided at the top of the rotating sleeve 42. Arc grooves are symmetrically provided on the ring edge, and the ring edge can be rotatably sleeved in the ring groove. A fixing pin is passed through the lower end of the fixed column 41, and both ends of the fixing pin are slidably engaged with a pair of ring grooves.

[0036] Example 6: The difference from Example 5 is that, in addition to the structural features of the aforementioned embodiments, a groove 5 is provided at the bottom of the table 1, and a number of unlocking rods 6 are slidably installed in the groove 5 through a shaft sleeve. One end of the unlocking rod 6 is aligned with the unlocking lever 43, and the other end is connected to the same pull rod 7. A vertical plate 8 is provided at one end of the groove 5, and the pull rod 7 is also slidably installed in the groove 5 through a shaft sleeve, and one end is movable through the vertical plate 8 and is fixed with a handle 9. A return spring 10 is provided on the pull rod 7, and one end of the return spring 10 is fixed to the pull rod 7, and the other end is in contact with the inner wall of the vertical plate 8.

[0037] like Figure 3 As shown, due to the adoption of the above-mentioned structure, when multiple clamps 2 need to be unlocked at the same time, the operator only needs to pull the handle 9, and the pull rod 7 slides through the shaft sleeve in the groove 5, driving the unlocking rod 6 connected thereto to move synchronously. The unlocking rod 6 follows the guide of the shaft sleeve and accurately transmits the moving force to the aligned unlocking lever 43, pushing the unlocking lever 43 to rotate, thereby triggering the rotation of the rotating sleeve 42 to achieve synchronous unlocking of the plug blocks 31 of each clamp 2.

[0038] The return spring 10 is compressed during the pulling process of the pull rod 7, storing elastic potential energy; when the operator releases the handle 9, the return spring 10 releases the elastic potential energy, pushes the pull rod 7 to reset, and drives the unlocking rod 6 back to the initial position. At the same time, the rotating sleeve 42 of each clamp 2 is also automatically reset with the cooperation of the reset slider 49, the reset groove 48, and the lifting groove 47, preparing for the next unlocking operation.

[0039] This structural design integrates the unlocking operations of multiple clamps 2 into one handle 9 control, greatly improving the unlocking efficiency and reducing the workload of the operator. The cooperation of the return spring 10 and the bushing and other components ensures the stability and reliability of the unlocking and resetting process. Even if the operation is frequent, it is not prone to failure, further optimizing the user experience of the automobile steering gear transfer stand.

[0040] Example 7: The difference from Example 6 is that, in addition to the structural features of the aforementioned embodiments, columns 11 are provided at the four corners of the top surface of the table top 1, columns 12 are provided at the top of each column 11, and L blocks 13 adapted to the columns 12 are provided at the four corners of the bottom surface of the table top 1.

[0041] like Figure 1 and Figure 2As shown, due to the adoption of the above-mentioned structure, when the transfer platforms need to be stacked, the operator aligns the L-block 13 on the bottom surface of one transfer platform with the column 12 on the top surface column 11 of another transfer platform, and then slowly lowers it. During the lowering process, the L-block 13 gradually embeds into it along the shape of the column 12, and the two transfer platforms are firmly connected together through the adaptation structure of the L-block 13 and the column 12. This stacking method not only saves storage space, but also after stacking, the transfer platforms can maintain a stable connection state, and are not prone to shaking or separation. When the transfer platforms need to be used, they can also be easily separated without affecting the normal use of a single transfer platform, thereby improving the convenience and space utilization of the transfer platforms during storage and transfer.

[0042] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
