DETAILED DESCRIPTION

[0038] The utility model will be further described in connection with the drawings below.

[0039] The utility model discloses an embodiment provides a kind of hanging support, it includes support part 1, telescopic hanging rod 2 and clamping piece 3.Support part 1 is configured to be detachably fixed to corresponding medical equipment, and first side surface of support part 1 is configured with first clamping groove 13;The end of telescopic hanging rod 2 is provided with the rotary part 21 of being rotatably cooperated in support part 1, and the first end surface of rotary part 21 corresponds first side surface, and first end surface is configured with second clamping groove 211;Clamping piece 3 is cooperated in two clamping grooves and is configured to be able to switch the cooperation state with two clamping grooves, and cooperation state includes that clamping piece 3 is simultaneously in first clamping groove 13 and second clamping groove 211 and clamping piece 3 is integrally in first clamping groove 13 or second clamping groove 211.

[0040] Specifically, the main structure of the hanging support of the utility model includes support part 1 and telescopic hanging rod 2, and the overall structure is as shown in the drawing Figure 1 And Figure 8 As shown in the drawing. Wherein support part 1 is configured as plate structure, mainly used to connect corresponding medical equipment, with corresponding medical equipment as the base of support, so that the volume of support part 1 itself can be greatly reduced, from the drawing Figure 1 And Figure 8 It can also be seen that the radial dimension of support part 1 itself is not much different from telescopic hanging rod 2. One end of telescopic hanging rod 2 is provided with rotary part 21, for connecting support part 1;As shown in the drawing Figure 2 And Figure 3As shown, the side surface of the rotating part 21 is configured with an interface 212, the end of the telescopic hanging rod 2 can be inserted into the interface 212, and then transversely inserted into a locking pin to realize the connection of the telescopic hanging rod 2 and the rotating part 21. The rotating part 21 is in a block structure as a whole, is assembled to the first side surface of the supporting part 1, and can rotate relative to the supporting part 1 in a plane parallel to the first side surface, so that the posture of the telescopic hanging rod 2 can be adjusted, for example, the telescopic hanging rod 2 can be adjusted to be upright or laid down, corresponding to the use state and the storage state respectively. At the same time, the telescopic hanging rod 2 itself can also be telescopic to meet the needs of different use heights.

[0041] Among them, the relative rotation or relative locking between the telescopic hanging rod 2 and the supporting part 1 is realized through the clamping piece 3. The first side surface of the supporting part 1 is provided with a first clamping groove 13, and the first end surface of the rotating part 21 corresponding to the first side surface is provided with a second clamping groove 211. When the rotating part 21 rotates relative to the supporting part 1 to correspond the second clamping groove 211 to the first clamping groove 13, the clamping piece 3 can be matched in the first clamping groove 13 and the second clamping groove 211 at the same time. At this time, due to the limiting action of the clamping piece 3, the rotating part 21 cannot rotate relative to the supporting part 1 any more. At this time, the telescopic hanging rod 2 and the supporting part 1 are in a relative locking state. The relative locking state can correspond to the telescopic hanging rod 2 in the upright use state. The locking function of the clamping piece 3 can keep the stability of the telescopic hanging rod 2 in the upright state when hanging the corresponding object (such as physiological saline). When it is needed to release the locking, the clamping piece 3 as a whole is moved into the first clamping groove 13 or the second clamping groove 211 through external force, so that the rotation locking of the clamping piece 3 on the telescopic hanging rod 2 and the supporting part 1 is released. Then the telescopic hanging rod 2 and the rotating part 21 as a whole can rotate relative to the supporting part 1 to the laid-down storage state.

[0042] Therefore, the hanging bracket of the present application directly connects the corresponding equipment with the supporting part 1 to take the equipment as the bracket base, which avoids the conventional base with large volume and weight. At the same time, based on the telescopic structure of the telescopic hanging rod 2 itself and the rotation connection structure between the telescopic hanging rod 2 and the supporting part 1, the adjustment of the hanging height can be realized, and the telescopic hanging rod 2 can be rotated as needed to make it upright or laid down, which meets the two aspects of needs of use and storage, and greatly improves the convenience of storage.

[0043] In one embodiment, the second clamping groove 211 is configured as a rotationally symmetrical structure, so that when the rotating part 21 rotates by a preset angle, the corresponding part of the second clamping groove 211 can correspond to the first clamping groove 13.

[0044] Specifically, as shown in the accompanying drawings Figure 2 With Figure 4As shown, in the embodiment, the second clamping groove 211 is configured as a cross-shaped rotational symmetric structure, and the first clamping groove 13 is configured as a linear structure, so that after the rotating part 21 rotates by 90° (i.e., the preset angle is 90°), the corresponding part of the second clamping groove 211 can correspond to the first clamping groove 13, so that the clamping piece 3 can realize the rotational locking of the telescopic hanging rod 2 and the support part 1 in two orientations that are opposite to each other by 90°, so that the telescopic hanging rod 2 can maintain the stability of its state in different orientations through the locking of the clamping piece 3. In the embodiment, the two orientations of the cross-shaped second clamping groove 211 that are opposite to each other by 90° correspond to the upright and horizontal laid-down states of the telescopic hanging rod 2, respectively, so that the stability of the telescopic hanging rod 2 in the use and storage states can be maintained through the locking of the clamping piece 3.

[0045] In addition, according to needs, the second clamping groove 211 can be configured as other rotational symmetric structures, for example, the relative angle between two adjacent parts of the second clamping groove 211 can be changed, and the second clamping groove 211 can be configured as a horizontal bar-shaped structure or other structures, so that in addition to being able to maintain the stability of the telescopic hanging rod 2 in the use and storage states, the other use angles of the telescopic hanging rod 2 in the use state can be further adjusted and stabilized, and the corresponding angles in the upright state are no longer limited, so that different use requirements can be met.

[0046] In one embodiment, as shown in the accompanying drawings Figure 2 With Figure 3 As shown, the first side of the support part 1 is configured with a rotating shaft part 14 extending outward, and the rotating part 21 is sleeved on the rotating shaft part 14 to realize the rotational cooperation between the rotating part 21 and the support part 1.

[0047] Preferably, as shown in the accompanying drawings Figures 2 to 5 As shown, the rotating part 21 is in a sleeve-shaped structure that is sleeved on the rotating shaft part 14, and in order to limit the position of the rotating part 21 in the axial direction of the rotating shaft part 14 and avoid the rotating part 21 from being separated from the rotating shaft part 14 in the axial direction, the rotating shaft part 14 is further configured with a corresponding limiting structure. According to needs, the limiting structure can have different structures that can be selected, for example, the surface of the rotating shaft part 14 is configured with a circumferentially extending ring groove 141, and the ring groove 141 is provided with an elastic stop ring 6 that partially protrudes from the ring groove 141, and the rotating part 21 is limited between the first side and the elastic stop ring 6, so that the position of the rotating part 21 in the axial direction of the rotating shaft part 14 is limited from both ends of the rotating part 21 by the first side and the elastic stop ring 6 on the rotating shaft part 14; for another example, the rotating shaft part 14 can be threadedly connected with at least one limiting sleeve ring (not shown in the accompanying drawings), and the specific structure of the limiting sleeve ring can directly adopt a nut, so that the rotating part 21 can also be limited in the axial direction between the first side and the limiting sleeve ring.

[0048] In one embodiment, the connecting position of the connecting end of the rotation shaft part 14 connected with the first side corresponds to the position where the first clamping groove 13 is located, the connecting end partially covers the first clamping groove 13, and the uncovered part of the first clamping groove 13 can correspond to the communicating second clamping groove 211; wherein the rotation shaft part 14 is internally configured with a central hole 142 extending along the axial direction thereof, and the state switching piece 4 connected with the clamping piece 3 is arranged in the central hole 142, and the end of the state switching piece 4 is exposed at the extending end of the rotation shaft part 14.

[0049] Specifically, as shown in the accompanying drawings Figures 2 to 5 , one end of the rotation shaft part 14 is directly connected at the position where the center of the first clamping groove 13 is located, that is, the center of the first clamping groove 13 corresponds to the rotation center of the rotating part 21, so that the end of the rotation shaft part 14 connected with the first side of the support part 1 shields the slot of the partial area of the first clamping groove 13. Based on this structure, the central hole 142 is configured in the interior of the rotation shaft part 14, and the state switching piece 4 (in this embodiment, the state switching piece 4 is configured in a rod shape) connected with the clamping piece 3 is arranged in the central hole 142. The clamping piece 3 can be pushed or pulled by the state switching piece 4, so as to control the position of the clamping piece 3 relative to the first clamping groove 13 and the second clamping groove 211, so as to switch the locking and unlocking states of the clamping piece 3 relative to the telescopic hanging rod 2.

[0050] In addition, the rotation shaft part 14 is arranged to correspond to the first clamping groove 13, and the state switching piece 4 is arranged in the central hole 142 of the rotation shaft part 14, because in this way, the positions of the state switching piece 4 and the clamping piece 3 in the circumferential direction and the radial direction do not change during the rotation of the rotating part 21, so that the number of the first clamping groove 13 and the second clamping groove 211 is only one, and when the clamping piece 3 is locked again after rotation, it is matched with the same first clamping groove 13 and second clamping groove 211, so that the structure and the locking and unlocking operation of the clamping piece 3 can be simplified.

[0051] In one embodiment, the end face of the connecting end is configured with a third clamping groove 143 corresponding to the first clamping groove 13, and the third clamping groove 143 can form a containing space with the second clamping groove 211 when the second clamping groove 211 rotates with the rotating part 21 to correspond to the first clamping groove 13, so as to at least partially contain the clamping piece 3.

[0052] Specifically, as shown in the accompanying drawings Figure 4 and Figure 5As shown, based on the correspondence between the rotating shaft part 14 and the first clamping groove 13, the rotating shaft part 14 itself does not affect the fitting of the clamping piece 3 in the first clamping groove 13. However, when the clamping piece 3 is fitted into the second clamping groove 211, it is obvious that the clamping piece 3 needs to at least partially enter the second clamping groove 211 from the first clamping groove 13, at which time the connecting end of the rotating shaft part 14 can interfere with the movement of the clamping piece 3. Therefore, a third clamping groove 143 corresponding to the second clamping groove 211 is arranged on the end face of the connecting end of the rotating shaft part 14, the side face of the third clamping groove 143 is in communication with the second clamping groove 211. In this embodiment, the third clamping groove 143 is equivalent to being embedded in the second clamping groove 211, and the two ends of the third clamping groove 143 are in communication with two parts at both ends of the second clamping groove 211 at a specific angle, that is, the third clamping groove 143 can jointly enclose an accommodation space with the second clamping groove 211 when the rotating part 21 is rotated to correspond to the first clamping groove 13, so as to eliminate the influence that the connecting end of the rotating shaft part 14 can interfere with the movement of the clamping piece 3 by using the third clamping groove 143.

[0053] In one embodiment, the center hole 142 is provided with an elastic piece 5, one end of the elastic piece 5 abuts against a first positioning step face arranged on the inner wall of the center hole 142, and the other end of the elastic piece 5 abuts against a second positioning step face arranged on the outer wall of the state switching piece 4; wherein the state switching piece 4 can keep the clamping piece 3 in a fitting state in the first clamping groove 13 and the second clamping groove 211 at the same time under the pre-tightening elastic force of the elastic piece 5.

[0054] Specifically, in order to ensure the stability of the relative state of the telescopic hanging rod to the support part in the hanging support at a corresponding angle, the pre-tightening elastic force of the elastic piece makes the clamping piece always in a locking state of simultaneously being in the first clamping groove and the second clamping groove to rotate and lock the telescopic hanging rod without external force. After the pre-tightening elastic force of the elastic piece is overcome by the external force acting on the state switching piece, the rotating and locking state of the clamping piece to the telescopic hanging rod can be released.

[0055] In one embodiment, the first positioning step face is closer to the first clamping groove 13 than the second positioning step face, the depth of the first clamping groove 13 is not less than the thickness of the clamping piece 3, and the depth of the second clamping groove 211 is less than the thickness of the clamping piece 3; or the second positioning step face is closer to the first clamping groove 13 than the first positioning step face, the depth of the first clamping groove 13 is less than the thickness of the clamping piece 3, and the depth of the second clamping groove 211 is not less than the thickness of the clamping piece 3.

[0056] Specifically, based on the pre-tightening elastic force of the elastic piece 5 to keep the rotating and locking state of the clamping piece 3 to the telescopic hanging rod 2, according to the different relative positions of the first positioning step face corresponding to the two ends of the elastic piece 5 to the second positioning step face in the axial direction of the rotating shaft part 14, the operation to unlock the rotating and locking state of the clamping piece 3 to the telescopic hanging rod 2 is slightly different, which is as follows:

[0057] As shown in the accompanying drawings Figure 4 andFigure 5 As shown, in the embodiment, the first positioning step surface is closer to the first clamping slot 13 than the second positioning step surface, and the second positioning step surface needs to move towards the first positioning step surface to overcome the pre-tightening elastic force of the elastic member 5. Therefore, in the embodiment, the state switching member 4 and the clamping member 3 as a whole need to move towards the position where the first clamping slot 13 is located. Therefore, to unlock the clamping member 3, the clamping member 3 as a whole needs to be separated from the second clamping slot 211 and enter the first clamping slot 13. Therefore, the depth of the first clamping slot 13 needs to be able to completely accommodate the clamping member 3, i.e., the depth needs to be not less than the thickness of the clamping member 3 in the depth direction of the first clamping slot 13. The pre-tightening elastic force of the elastic member 5 will make the clamping member 3 enter the second clamping slot 211. At this time, in order to ensure that the clamping member 3 enters the second clamping slot 211 while also being in the first clamping slot 13, it is necessary to ensure that the second clamping slot 211 cannot completely accommodate the clamping member 3, so the depth of the second clamping slot 211 needs to be less than the thickness of the clamping member 3. At this time, from the end of the extension end of the state switching member 4 exposed to the rotating shaft part 14, the operation of unlocking needs to press the end of the state switching member 4. Therefore, a pressing operation part 41 with a certain area is arranged at the end of the extension end of the state switching member 4 exposed to the rotating shaft part 14 for pressing.

[0058] If the second positioning step surface is closer to the first clamping slot 13 than the first positioning step surface, and the second positioning step surface needs to move towards the first positioning step surface to overcome the pre-tightening elastic force of the elastic member 5. Therefore, the state switching member 4 and the clamping member 3 as a whole need to move away from the position where the first clamping slot 13 is located. Therefore, to unlock the clamping member 3, the clamping member 3 as a whole needs to be separated from the first clamping slot 13 and enter the second clamping slot 211. Therefore, the depth of the second clamping slot 211 needs to be able to completely accommodate the clamping member 3, i.e., the depth needs to be not less than the thickness of the clamping member 3 in the depth direction of the second clamping slot 211. The pre-tightening elastic force of the elastic member 5 will make the clamping member 3 enter the first clamping slot 13. At this time, in order to ensure that the clamping member 3 enters the first clamping slot 13 while also being in the second clamping slot 211, it is necessary to ensure that the first clamping slot 13 cannot completely accommodate the clamping member 3, so the depth of the first clamping slot 13 needs to be less than the thickness of the clamping member 3. At this time, from the end of the extension end of the state switching member 4 exposed to the rotating shaft part 14, the operation of unlocking needs to pull the end of the state switching member 4. Therefore, a pulling operation part (not shown in the figure) capable of being gripped by a person's hand is arranged at the end of the extension end of the state switching member 4 exposed to the rotating shaft part 14.

[0059] For the above two schemes, in the first scheme, the state switching member 4 and the clamping member 3 as a whole are located in the first clamping slot 13 after unlocking, and do not rotate with the rotating part 21; in the second scheme, the state switching member 4 and the clamping member 3 as a whole are located in the second clamping slot 211 after unlocking, and will rotate with the rotating part 21. Therefore, from the perspective of operational convenience, the first scheme is more preferred.

[0060] In one embodiment, the end of the telescopic hanging rod 2 is provided with a hook assembly 7, which comprises a connecting piece 72 mounted at the end of the telescopic hanging rod 2 and a hook body 71 hingedly connected to the connecting piece 72 through a pin shaft.

[0061] Specifically, as shown in the drawings Figure 6 With Figure 7 The main body of the connecting piece 72 is in a columnar structure similar to the rod structure of the telescopic hanging rod 2, and the connecting piece 72 can be fixed at the end of the rod of the telescopic hanging rod 2 in a threaded or interference fit manner. The hook body is hingedly connected to the side surface of the connecting piece 72, which can adapt to different hanging angles.

[0062] In one embodiment, the telescopic hanging rod 2 is composed of a plurality of rod members nested in sequence, and two rod members adjacent to each other in the radial direction of the telescopic hanging rod 2 are an inner sleeve rod 201 and an outer sleeve rod 202. The inner sleeve rod 201 and the outer sleeve rod 202 can move relative to each other in the axial direction, so as to realize relative telescopic extension and contraction. Figure 6 With Figure 7 As shown in the drawings When the inner sleeve rod 201 and the outer sleeve rod 202 are relatively retracted, the locking hole 2021 corresponds to the telescopic locking piece 22, so that the telescopic locking piece 22 can be partially clamped into the locking hole 2021, thereby realizing the locking of the telescopic extension and contraction between the inner sleeve rod 201 and the outer sleeve rod 202. When it is needed to relatively extend the inner sleeve rod 201 and the outer sleeve rod 202, the telescopic locking piece 22 is pressed into the assembly groove 2011 to overcome the elastic force of the elastic member, so that the telescopic locking piece 22 is separated from the locking hole 2021, thereby realizing the unlocking of the telescopic extension and contraction between the inner sleeve rod 201 and the outer sleeve rod 202.

When connected with the ablation device body, the bottom plate part 11 is inserted into the limiting groove on the bottom surface of the ablation device body from the side, and the support body 12 is attached to the side of the ablation device body, and then the threaded connecting piece 72 is inserted into the connecting hole of the bottom plate part 11 to the threaded hole at the bottom of the limiting groove, so that the bottom plate part 11 is fixed on the bottom surface of the ablation device body, and then the suspension bracket is fixed on the ablation device body and directly uses the ablation device body as the bracket base.
