[0053] The embodiment of the present application discloses a support arm mounting assembly and a support arm device to meet the requirements of stable and reliable installation, no damage to the support arm, no influence on the rotation of the support arm, etc.

[0054] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0055] The support arm mounting assembly provided by the present application is used for mounting a support arm on a corresponding device, which is applicable but not limited to mounting the support arm on a medical trolley, a medical lifting tower, a medical main machine, a hospital bed and the like. The end of the support arm is mounted with a medical device, including but not limited to a probe and the like. For example, the probe of an endoscope ultrasonic diagnostic device is fixed to the end of the support arm, and the support arm can be mounted on a medical trolley or a lifting tower through the support arm mounting assembly. The main body structure of the support arm is not specifically limited in the present application. In an optional example, the support arm includes multiple support arm units, and adjacent support arm units are rotationally connected. It should be noted that the plural in the present application refers to two or more. The support arm mounting assembly provided by the present application is applicable to a support arm with a connecting shaft end, which can be one end of the support arm itself or a protruding part provided on the support arm for connection. The cross section of the connecting shaft end is circular, i.e. the connecting shaft end is in the shape of a cylinder, so as to meet the requirement of rotation in the state of support arm installation. The structure of the support arm mounting assembly is mainly described in the following embodiments.

[0056] In some specific embodiments, please refer to Figures 1-6The support arm mounting assembly provided by the application comprises a base 100 and a clamp 200. The base 100 is arranged on a corresponding device to which a support arm 300 is to be mounted. The base 100 is provided with a first fixing portion 101 for mounting the clamp 200. The clamp 200 comprises a clamp body 201 and a second fixing portion 203. The clamp body 201 is used to tightly hold the connecting shaft end 310 of the support arm 300 and to vertically support the connecting shaft end 310. The second fixing portion 203 is used to connect with the first fixing portion 101 so as to mount the clamp 200 on the base 100 and thus mount the support arm 300 on the corresponding device. The second fixing portion 203 is arranged on the clamp body 201. It can be understood that the second fixing portion 203 and the clamp body 201 can be an integral structure or separate parts connected by a conventional fixing manner. The second fixing portion 203 is used to connect with the first fixing portion 101. The shape of the second fixing portion 203 corresponds to the shape of the first fixing portion 101. The clamp body 201 is provided with a receiving groove 202 for receiving the connecting shaft end 310 of the support arm 300. The periphery of the receiving groove 202 is used to apply pressure to the outer periphery of the connecting shaft end 310. The shape of the receiving groove 202 corresponds to the shape of the connecting shaft end 310. It can be understood that the connecting shaft end 310 can be inserted into the receiving groove 202. The connecting shaft end 310 can be inserted into the receiving groove 202 by using the elasticity of at least part of the clamp body 201 or by setting the clamp body 201 as a split structure and inserting the connecting shaft end 310 into the receiving groove 202 by the activity of the split structure. The base 100 is arranged on the device in a mounting direction. The receiving groove 202 of the clamp body 201 has an upward opening. Specifically, the receiving groove 202 extends vertically. When the connecting shaft end 310 is arranged in the receiving groove 202, the clamp body 201 can vertically support the connecting shaft end 310 and thus support the support arm 300, i.e. mount the support arm 300 on the corresponding device. When the connecting shaft end 310 is arranged in the receiving groove 202, the periphery of the receiving groove 202 can contact and apply pressure to the outer periphery of the connecting shaft end 310 so as to tightly hold the connecting shaft end 310 and prevent it from shaking. It can be understood that the tight holding in the application means that the clamp 200 can limit the shaking of the connecting shaft end 310. Specifically, the size of the pressure applied by the periphery of the receiving groove 202 to the connecting shaft end 310 can be set by matching the inner diameter of the receiving groove 202 with the outer diameter of the connecting shaft end 310 so that the connecting shaft end 310 can rotate in the receiving groove 202.

[0057] The support arm mounting assembly provided in the application is used to mount the support arm 300 on the trolley, tower crane and other equipment by the cooperation of the base 100 and the clamp 200. During the mounting, the base 100 is arranged at the corresponding position of the equipment, the connecting shaft end 310 of the support arm 300 is inserted into the accommodating groove 202 of the clamp 200, the periphery of the side wall of the accommodating groove 202 is in contact with the outer periphery of the connecting shaft end 310 and applies pressure to the outer periphery of the connecting shaft end 310, so as to tightly hold the connecting shaft end 310 and prevent it from shaking, then the second fixing part 203 of the clamp 200 is inserted into the first fixing part 101 of the base 100 and connected with the base 100, so as to mount the support arm 300 on the corresponding equipment, and the end of the support arm 300 can be connected with the medical equipment such as the ultrasonic probe. By using the support arm mounting assembly, compared with the conventional screw 400 pressing method, the support arm 300 is mounted reliably and has small shaking amount, and at the same time, the connecting shaft end 310 of the support arm 300 can be in surface contact, which is fixed firmly and is not easy to damage the support arm 300. In addition, by adjusting the holding force of the side wall of the accommodating groove 202 on the connecting shaft end 310, the clamp 200 is stably realized, and the support arm 300 can rotate in the accommodating groove 202, that is, the support arm 300 will not be locked, so as to meet the need of adjusting the position of the support arm 300.

[0058] In some embodiments, the clamping device 200 comprises a clamping seat 210 and a clamping block 220. The top end of the clamping seat 210 is provided with a groove 211, and the side wall of the groove 211 is provided with a notch 212 extending to the top end of the clamping seat 210. The clamping block 220 is movably arranged in the notch 212, and the clamping block 220 is fixed in the state of surrounding the clamping seat 210 to form a receiving groove 202, and the second fixing part 203 is arranged at the bottom end of the clamping seat 210. In this embodiment, the clamping device 200 adopts a split structure, that is, it comprises a clamping seat 210 and a clamping block 220, which cooperate to form the above-mentioned receiving groove 202. Specifically, the clamping seat 210 has a groove 211 and a notch 212, and the notch 212 is located on the side wall of the groove 211, and the notch 212 extends to the top end of the clamping seat 210, that is, the end of the clamping seat 210 forming the slot of the groove 211, and the clamping block 220 is arranged corresponding to the notch 212, and the clamping block 220 can move relative to the clamping seat 210, so that when the clamping block 220 exits from the notch 212, the receiving groove 202 surrounded by the clamping block 220 and the clamping seat 210 is opened, so that the connecting shaft end 310 can be inserted thereinto. After the connecting shaft end 310 is inserted into the appropriate position, the clamping block 220 is placed in the notch 212 and fixed, so as to tightly clamp the connecting shaft end 310. The clamping device 200 adopts the above-mentioned split structure, the connecting shaft end 310 is convenient to disassemble and assemble, and the tightness of the clamping device 200 can be conveniently adjusted by adjusting the position of the clamping block 220 relative to the clamping seat 210. In addition, the clamping device 200 can be compatible with the support arm 300 whose diameter of the connecting shaft end 310 is within a certain diameter range, so that the installation assembly of the support arm 300 has better universality. In this embodiment, part of the clamping seat 210 and the clamping block 220 form the above-mentioned clamping main body 201, and the other part of the clamping seat 210 can be used as the second fixing part 203. For example, referring to Figure 4 , the clamping seat 210 comprises a seat body and a second fixing part 203 protruding from the end face of the seat body, and the seat body is provided with the above-mentioned groove 211 and notch 212, and the seat body and the clamping block 220 form the above-mentioned clamping main body 201.

[0059] In some embodiments, the clamping block 220 is detachably connected with the clamping seat 210. That is, the movable connection mode of the clamping block 220 and the clamping seat 210 comprises detachable connection. During installation, the clamping block 220 can be first detached from the clamping seat 210, the connecting shaft end 310 is inserted into the groove 211 of the clamping seat 210, then the clamping block 220 is installed in the notch 212 of the clamping seat 210, and the clamping block 220 and the clamping seat 210 are fixedly connected, so as to tightly clamp the connecting shaft end 310 in the receiving groove 202 surrounded by the clamping block 220 and the clamping seat 210. The clamping block 220 and the clamping seat 210 adopt detachable connection, and the clamping block 220 can be integrally detached from the clamping seat 210, so that a larger space is provided for the installation of the connecting shaft end 310, and the interior of the groove 211 is convenient to maintain and adjust.

[0060] In some other embodiments, instead of detachable connection between the clamp block 220 and the clamp seat 210, the clamp block 220 can be in sliding connection with the clamp seat 210, i.e. the clamp block 220 is connected to the clamp seat 210 and can slide relative to the clamp seat 210. The clamp block 220 is slidably arranged in the notch 212 along the radial direction of the accommodating groove 202 and can be locked to the clamp seat 210 to tightly hold the connecting shaft end 310. During installation, the clamp block 220 can be first moved outward along the radial direction of the accommodating groove 202, the connecting shaft end 310 is inserted into the groove 211 of the clamp seat 210, and then the clamp block 220 is moved inward along the radial direction of the accommodating groove 202. When the clamp block 220 is moved to a proper position, the clamp block 220 is locked, so that the connecting shaft end 310 is tightly held. The clamp block 220 and the clamp seat 210 are in sliding connection, which can facilitate the disassembly and assembly of the connecting shaft end 310, and the clamp block 220 will not be separated from the clamp seat 210, thereby avoiding the loss of the clamp block 220.

[0061] Specifically, the clamp block 220 and the clamp seat 210 are connected by screws. On the one hand, the screw connection is convenient and reliable. On the other hand, the screw connection can conveniently adjust the tightness of the clamp block 220, i.e. by tightening the screw to adjust the position of the clamp block 220 relative to the clamp seat 210, and then adjust the pressure applied by the clamp seat 210 and the clamp block 220 to the outer surface of the connecting shaft end 310. Specifically, the clamp seat 210 is provided with a threaded hole, and the clamp block 220 is provided with a fastening through hole. The screw is arranged in the fastening through hole and threadedly cooperates with the threaded hole. The length of the screw screwed into the threaded hole is different, and the tightness of the clamp 200 formed by the clamp block 220 and the clamp seat 210 relative to the connecting shaft end 310 is also different.

[0062] In the above embodiments, the clamp body 201 adopts a split structure. In some other embodiments, the clamp body 201 can also adopt an integrated structure. In one way, at least part of the clamp body 201 is made of a deformable material. When the connecting shaft end 310 is inserted into the accommodating groove 202, the deformable material part of the clamp body 201 deforms correspondingly, and the connecting shaft end 310 can be smoothly inserted into the accommodating groove 202. The restoring force generated by the deformation of the deformable material part can act on the connecting shaft end 310, thereby tightly holding the connecting shaft end 310. In addition, the size of the holding force of the side wall of the accommodating groove 202 on the connecting shaft end 310 can be controlled by selecting the specific material of the deformable material part.

[0063] In another way, the side wall of the accommodating groove 202 is provided with a slit along the extension direction of the accommodating groove 202. By providing the slit, it can be deformed when the connecting shaft end 310 is inserted into the accommodating groove 202 to meet the insertion of the connecting shaft end 310, and the side wall of the accommodating groove 202 tightly holds the connecting shaft end 310 under the action of the restoring force after the connecting shaft end 310 is inserted. That is, in the above embodiment, the elastic deformation is provided by the at least partially elastic material of the clamping body 201, and in this embodiment, the elastic deformation is provided by the slit on the side wall of the accommodating groove 202, which can reliably hold the connecting shaft end 310, and the integrated structure is convenient for processing and preparation, and the overall reliability is high.

[0064] In some embodiments, the clamping 200 further comprises a clamping sleeve 230, which is arranged in the accommodating groove 202, and the clamping sleeve 230 has a slot and is used to be sleeved on the connecting shaft end 310. By arranging the clamping sleeve 230 between the connecting shaft end 310 and the clamping body 201, the clamping sleeve 230 can be made of a material with lower hardness and better wear resistance to reduce the wear of the connecting shaft end 310 and the clamping body 201, and when the clamping sleeve 230 is worn to a certain extent, it can be conveniently replaced to save the cost of replacing the connecting shaft end 310 or the clamping body 201. The clamping sleeve 230 has a slot, that is, the clamping sleeve 230 is a semi-open structure, and the inner diameter of the clamping sleeve 230 can change within a certain range. Specifically, the clamping sleeve 230 is in interference fit with the clamping body 201. When assembling, the connecting shaft end 310 is sleeved into the clamping sleeve 230, and then the connecting shaft end 310 sleeved with the clamping sleeve 230 is placed into the accommodating groove 202, the side wall of the accommodating groove 202 tightly holds the clamping sleeve 230, and at the same time drives the inner diameter of the clamping sleeve 230 to shrink to tightly hold the supporting arm 300, thereby preventing the supporting arm 300 from shaking. Specifically, at this time, the supporting arm 300 can be rotated to adjust the position and cannot be pulled out of the clamping sleeve 230.

[0065] In some embodiments, the first fixing part 101 is a mounting hole, and the second fixing part 203 is an insertion part for inserting into the mounting hole. The insertion part can protrude from the clamping body 201, and the end face of the clamping body 201 provided with the insertion part is used to abut against the end face of the base 100 provided with the mounting hole, so as to realize the positioning and reliable installation of the clamping 200 and the base 100. By arranging the base 100 in the installation direction of the equipment, the hole opening of the mounting hole faces upward, and after the insertion part is inserted into the mounting hole, the slot of the accommodating groove 202 is inserted.
