Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figure 1-4 This embodiment of the present invention provides an ultra-low-position hydraulically adjustable electric operating table, comprising: The support assembly 100 includes a base 101, a column 102 fixedly connected to the end of the base 101, a sleeve 103 sleeved on the end of the column 102, a connector 104 fixedly connected to the end of the sleeve 103, a support rod 105 rotatably mounted on the end of the connector 104, and a support plate 106 fixedly connected to the end of the support rod 105. The support rods 105 are symmetrically arranged on the bottom side wall of the support plate 106. The adjusting assembly 200 includes a hydraulic rod 201 fixedly connected inside the support rod 105, a support block 202 fixedly connected to the end of the hydraulic rod 201, a connecting rod 203 fixedly connected to the side wall of the sleeve 103, a positioning seat 204 fixedly connected to the side wall of the connecting rod 203, a support rod 205 rotatably inserted into the middle of the positioning seat 204, and a positioning block 206 hinged to the end of the support rod 205. The end of the positioning block 206 is bolted to the side wall of the support rod 105, and the end of the support block 202 slides in contact with the bottom of the support plate 106.

[0019] The base 101 provides fixed ground support for the entire equipment. The column 102 fixed at its end serves as the vertical load-bearing body. A sleeve 103 is fitted onto the end of the column 102, forming a relatively sliding telescopic structure that provides a basic travel for height adjustment. The connector 104 at the end of the sleeve 103 is connected to the support rod 105 via a rotatable engagement. The support rod 105 is symmetrically arranged at the bottom of the support plate 106, forming a balanced load-bearing structure on both sides. The tilt angle of the support plate 106 is adjusted using hydraulic drive and multi-link positioning. The hydraulic rod 201 is fixed inside the support rod 105, and its end, the support block 202, slides in contact with the bottom of the support plate 106. The telescopic movement of the hydraulic rod pushes the support block to slide along the bottom of the support plate, generating a tilting thrust. Simultaneously, the connecting rod 203 on the side wall of the sleeve 103 is rotatably connected to the support rod 205 via a positioning seat 204. The positioning block 206 hinged at the end of the support rod 205 is fixed to the side wall of the support rod 105 by bolts, forming an adjustable linkage support structure. When the hydraulic rod pushes the support plate to tilt, the support rod 205 rotates around the positioning seat 204. The tilt angle is limited by the fixed relationship between the positioning block and the support rod, thus achieving attitude locking.

[0020] Specifically, the adjustment assembly 200 also includes a housing 207 fixedly connected to the end of the connecting rod 203, a handle 208 rotatably mounted on the side wall of the housing 207, a main gear 209 adapted to be mounted on the end of the handle 208, and a gear plate 210 fixedly connected to the side wall of the end of the column 102. The teeth on the side wall of the main gear 209 mesh with the teeth on the side wall of the gear plate 210. A transmission shaft 211 is rotatably connected to the side wall of the housing 207. The housing 207 is symmetrically arranged at the end of the transmission shaft 211. A secondary gear 212 is fixedly connected to the end of the transmission shaft 211. The teeth on the side wall of the secondary gear 212 mesh with the teeth on the side wall of the main gear 209.

[0021] The synchronous transmission system comprises a housing 207, a handle 208, a main gear 209, a gear plate 210, a transmission shaft 211, and a secondary gear 212. The housing 207 is fixed to the end of the connecting rod 203 and symmetrically arranged at both ends of the transmission shaft 211. The handle 208 is rotatably mounted on the side wall of the housing 207, and its end-fitting main gear 209 meshes with the gear plate 210 on the side wall of the column 102. When the handle 208 is rotated, the main gear 209 moves vertically along the gear plate 210, causing the sleeve 103 to rise and fall along the column 102, thereby driving the support plate 106 to complete height adjustment. To ensure synchronous adjustment on both sides, the transmission shaft 211 connects the two housings, and its end-fitting secondary gear 212 meshes with the main gear 209, forming a symmetrical transmission structure. This avoids tilting of the support plate caused by unilateral adjustment and ensures consistent horizontal height adjustment.

[0022] Furthermore, a locking block 213 is fixedly connected to the side wall of the support rod 105, and a locking groove is opened in the middle of the locking block 213 to cooperate with the support rod 205.

[0023] The locking block 213 is used to fix the support rod 205. When the operating table needs to be folded, the support rod 205 is pulled out from the middle of the positioning seat 204, and then the support rod 205 is locked in the middle of the locking block 213 for easy storage.

[0024] Preferably, a support rod 107 is fixedly connected to the side wall of the support rod 105, and a support plate 106 is fixedly connected to the side wall of the support rod 107. The support rod 105 is symmetrically installed at the ends of the support rod 107.

[0025] To enhance support stability, a bearing rod 107 is added to the side wall of the support rod 105, and the support plate 106 is fixed to the side wall of the bearing rod 107. Through the lateral force dispersion effect of the bearing rod, the support plate is prevented from deforming due to local force concentration.

[0026] It should be noted that the side wall of the support rod 105 is provided with a sliding groove, the end of the connector 104 is slidably inserted into the middle of the sliding groove on the side wall of the support rod 105, and the end of the connector 104 is rotatably mounted with a guide wheel 108, the side wall of the guide wheel 108 is in rolling contact with the inner wall of the support rod 105.

[0027] The support rod 105 has a groove on its side wall, and the end of the connector 104 is slidably inserted into the groove. The guide wheel 108, which is rotatably installed at the end, rolls in contact with the inner wall of the support rod 105. This not only allows for fine adjustment of the angle of the support rod relative to the connector, but also reduces frictional loss during rotation and ensures the flexibility of posture adjustment.

[0028] Preferably, a roller 109 is rotatably mounted on the side wall of the sleeve 103, and the side wall of the roller 109 makes rolling contact with the end side wall of the column 102.

[0029] Among them, the roller 109 rotatably mounted on the side wall of the sleeve 103 makes rolling contact with the end side wall of the column 102, converting the sliding friction between the sleeve and the column into rolling friction, which significantly reduces the mechanical resistance during height adjustment and improves the smoothness of operation.

[0030] In use, the operator rotates the handle 208 on the side wall of the housing 207, driving the main gear 209 at the end of the handle 208 to rotate. Since the main gear 209 meshes with the toothed plate 210 fixed on the side wall of the column 102, the main gear 209 moves vertically along the toothed plate 210 when it rotates, thereby driving the sleeve 103 to move up and down along the column 102. At the same time, the transmission shaft 211 connects the housings 207 arranged symmetrically on both sides, and the auxiliary gear 212 at its end meshes with the main gear 209, so that the main gears 209 on both sides move synchronously along the toothed plate 210, ensuring that the lifting and lowering actions of the sleeve 103 are consistent on both sides. The roller 109 on the side wall of the sleeve 103 makes rolling contact with the side wall of the column 102, converting sliding friction into rolling friction and improving the smoothness of operation.

[0031] When the operating table needs to be stored, loosen the bolts connecting the positioning block 206 and the support rod 105, pull the support rod 205 out of the positioning seat 204, and then snap the support rod 205 into the slot of the side wall snap block 213 of the support rod 105 to achieve fixed storage of the support rod 205, reduce the space occupied by the equipment, and facilitate storage and transportation.

[0032] In summary, the synchronous transmission system formed by the drive shaft 211 and the auxiliary gear 212 enables simultaneous adjustment of the operating table height on both sides, effectively preventing the table surface (support plate 106) from tilting and ensuring horizontal accuracy in the ultra-low position. The hydraulic rod 201, in conjunction with the multi-link positioning structure, can be adapted to the installation and use of support plates 106 of different specifications, thus improving its applicability. The rollers 109 on the side wall of the sleeve 103 work in conjunction with the guide wheels 108 inside the support rod 105 to improve the smoothness of operation, reduce component wear, and extend the service life of the equipment. The symmetrically arranged support rods 105 and the added load-bearing rods 107 prevent localized stress concentration on the support plate 106 through force dispersion, enhancing structural strength and load-bearing capacity, and adapting to the surgical needs of patients of different weights. The ultra-low position adjustment stroke design can meet the operational needs of special scenarios such as pediatric surgery and surgery for elderly patients, improving the clinical adaptability of the equipment. The design of the combination of the locking block 213 and the support rod 205 enables the support rod 205 to be detached and stored, reducing the space occupied when the equipment is not in use, facilitating the space planning of the operating room and the transportation and storage of equipment, and improving the ease of use.
