Description

Technical Field

[0001] The utility model mainly relates to the technical field of electric operating tables, in particular to an ultra-low position electric operating table. Background Art

[0002] The ultra-low-position electric operating table is an operating table that can be raised, lowered and tilted. The electric operating table has the characteristic of facilitating the surgeon to directly adjust the operating position.

[0003] In order to facilitate the movement of the electric operating bed, the prior art provides a groove on the base of the electric operating bed and installs a hydraulic device and rollers in the groove. When the electric operating bed needs to be moved, the hydraulic device is used to push the rollers out of the groove, thereby achieving the mobility of the electric operating bed.

[0025] Please refer to the attached Figure 1-3A super-low-position electric operating bed comprises a base 1, a hydraulic system 2 and a bed body 3. The hydraulic system 2 is installed on the upper surface of the base 1, and the bed body 3 is installed on the movable end of the hydraulic system 2. A first groove is opened at the center of the lower surface of the base 1, and a fixed bidirectional hydraulic rod 6 is connected and fixed at the top center of the first groove, and a fixed connecting plate 7 is connected to both movable ends of the bidirectional hydraulic rod 6, and a fixed connecting rod 4 is connected to both the front and rear sides of a side of the connecting plate 7 away from the hydraulic rod, and one end of the connecting rod 4 away from the connecting plate 7 is connected to a fixed supporting block 11 with an isosceles trapezoidal cross section, and then second grooves are opened at the four corners of the lower surface of the base 1, and a through groove is opened between the first groove and the second groove, and one end of the connecting rod 4 away from the connecting plate 7 is inserted into the through groove.

[0026] A support block 12 is slidably connected in the second groove, a third groove is formed on a side of the support block 12 facing outside the second groove, and a roller 13 is arranged in the third groove, a speaker groove which is connected to the third groove and has the same size as the supporting block 11 is formed on a side of the support block 12 facing inside the second groove, and a rectangular rod 14 is inserted into the speaker groove, and one end of the rectangular rod 14 is connected and fixed to the roller 13.

[0027] By slidingly connecting the support block 12 in the second groove and installing the roller 13 in the support block 12, when the abutment block 11 contacts the support block 12, the support force that supports the electric operating bed to leave the ground and move upward is borne by the support block 12, thereby reducing the probability of damage to the roller 13, and a connecting structure composed of a connecting plate 7 and a connecting rod 4 is arranged in the first groove, and the connecting structure is connected and fixed to the two movable ends of the two-way hydraulic rod 6. When the movable ends of the two-way hydraulic rod 6 are extended at the same time, the connecting structure can be used to simultaneously drive the four rollers 13 to move downward, thereby saving the use of the hydraulic device.

[0028] Preferably, the connecting member includes a connecting plate 7, and the two movable ends of the bidirectional hydraulic rod 6 are connected and fixed with the connecting plate 7. A connecting rod 4 corresponding to the position of the second groove is connected and fixed on the side of the connecting plate 7 facing the second groove. The connecting rod 4 is inserted in the through groove, and the supporting block 11 is connected and fixed to the lower surface of the connecting rod 4 facing the second groove.

[0029] A fixed pipe sleeve 9 is connected to the top of the second groove, and a movable rod 10 is inserted into the end of the pipe sleeve 9 away from the top of the second groove. One end of the movable rod 10 in the pipe sleeve 9 is connected to a fixed elastic member 8, and the elastic member 8 is a spring. The elastic member 8 is in a normal state. The end of the elastic member 8 away from the movable rod 10 is connected and fixed to the pipe sleeve 9, and the end of the movable rod 10 away from the pipe sleeve 9 is connected and fixed to the support block 12.

[0030] In order to enhance the protection of the bidirectional hydraulic rod 6 in the first groove, a protection plate 5 is installed at the opening of the first groove.

[0031] The specific operation process of the utility model is as follows: start the two-way hydraulic rod 6, the two movable ends of the two-way hydraulic rod 6 are extended and drive the connecting plate 7 and the connecting rod 4 to move toward the second groove, thereby driving the supporting block 11 to squeeze the supporting block 12, so that the supporting block 12 and the roller 13 move downward. When the supporting block 12 contacts the ground and cannot continue to move downward, the supporting block 11 squeezes the supporting block 12 to move the entire electric operating bed upward, and the force of the entire electric operating bed when moving upward is all applied to the supporting block 12, and the supporting block 12 is used to support the entire electric operating bed, thereby protecting the roller 13 and avoiding damage to the roller 13.

[0032] As the entire electric operating bed moves upward, the elastic member 8 is gradually in a stretched state. When the abutment block 11 continues to reach the horn groove, the abutment block 11 no longer contacts the support block 12. The support block 12 moves upward under the pull of the elastic member 8, but the rectangular rod 14 is still abutted by the abutment block 11 so that the roller 13 does not move upward. When the support block 12 is separated from the ground, the roller 13 contacts the ground, thereby the entire electric operating bed can be moved.

[0033] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
