[0036] The utility model provides a support assembly 100 which is applied to an endoscope system.

[0037] In the embodiments of the present utility model, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The support assembly 100 includes a shell assembly 110 and a rotating frame 120. The shell assembly 110 is used to be fixedly installed on the back of the endoscope host 200; one end of the rotating frame 120 is rotatably installed on the shell, and the other end is formed with a gripping portion 120a.

[0038] The shell assembly 110 is used to be installed on the endoscope host 200, for example, installed on the back or side of the endoscope host 200, which can be achieved by screw connection, snap connection or magnetic connection. The shell assembly 110 is mainly used to connect between the rotating frame 120 and the endoscope host 200, so that when the rotating frame 120 rotates relative to the shell assembly 110, the rotating frame 120 rotates relative to the endoscope host 200. The setting of the shell assembly 110 makes it unnecessary for the endoscope host 200 to change its own structure in order to set the rotating frame 120. It only needs to install the overall structure formed by the shell assembly 110 and the rotating frame 120 on the endoscope host 200. It is more convenient to install it through the shell assembly 110 and the back of the endoscope host 200, reducing the space occupied inside the endoscope host 200. The shell assembly 110 can be an integrally formed shell, or it can be formed by connecting a plurality of components that are separately arranged.

[0039] In actual application, when the rotating frame 120 rotates to different positions, the angle between it and the endoscope host 200 (or the shell group 110) is also different, so that the installation angle of the endoscope host 200 can be adjusted. The rotating frame 120 has a folded state and a supported state during the rotation process. When the rotating frame 120 rotates to the supported state, the end of the rotating frame 120 away from the shell group 110 and the bottom of the endoscope host 200 jointly form a supporting surface, thereby achieving the effect of supporting the endoscope host 200 by a rotating frame 120. In addition, by forming a gripping portion 120a at the other end of the rotating frame 120 (i.e., the end of the rotating frame 120 away from the shell group 110), when the rotating frame 120 rotates to a state that is almost parallel to the shell group 110 and the gripping portion 120a is located above the rotating shaft of the rotating frame 120, the user can hold the gripping portion 120a to achieve the effect of carrying the endoscope host 200. With such a configuration, the rotating frame 120 in the technical solution of the utility model can not only achieve the effect of supporting the endoscope body, but also achieve the function of being carried by the user, so that it is convenient for the user to carry the endoscope system using the bracket assembly 100. The rotating frame 120 can be a rectangular frame structure or a circular frame structure. In this case, the structure of the rotating frame 120 itself makes the rotating frame 120 form a hollow structure, and the hollow structure can be used as a gripping portion 120a for the user to grip. Alternatively, the rotating frame 120 is a plate structure, and the gripping portion 120a is separately provided at one end of the plate structure away from the shell group 110. The gripping portion 120a can be a gripping handle protruding from the plate structure, or can be a structure such as a hand gripping groove opened on the plate structure.

[0040] The technical solution of the utility model is that one end of the rotating frame 120 is rotatably mounted on the shell group 110, and the shell group 110 is used to be fixedly mounted on the back of the endoscope mainframe 200, so that when the rotating frame 120 rotates relative to the shell group 110, the rotating frame 120 can rotate relative to the endoscope mainframe 200, so that the end of the rotating frame 120 away from the shell group 110 and the bottom of the endoscope mainframe 200 can be used together as a support surface to support the endoscope mainframe 200. In addition, a gripping portion 120a is formed at the other end of the rotating frame 120, so that the user's hand can also grip the gripping portion 120a to achieve the effect of hand-carrying the endoscope mainframe 200 and the bracket assembly 100, so as to facilitate carrying and transporting the endoscope mainframe 200. The bracket assembly 100 in the technical solution of the utility model can achieve the effect of supporting the endoscope main body and the effect of being hand-carried by the user, so that the bracket assembly 100 has multiple functions.

[0041] In an example, please refer to Figures 1 to 8The shell assembly 110 includes a shell body 111 and a fixing bracket 112 . The fixing bracket 112 is detachably connected to the shell body 111 . One end of the rotating frame 120 is rotatably connected to the fixing bracket 112 .

[0042] It is understandable that the volume of the shell body 111 is larger than that of the fixed bracket 112. Therefore, if the rotating frame 120 is directly connected to the shell body 111, the shell body 111 is easy to block the installation line of sight and the operation is inconvenient. In this example, by detachably connecting the fixed bracket 112 to the shell body 111, one end of the rotating frame 120 is rotatably connected to the fixed bracket 112. In the assembly process of the bracket assembly 100, the rotating frame 120 can be connected to the fixed bracket 112 first, and then the fixed bracket 112 can be installed on the shell body 111, so that the assembly process of the bracket assembly 100 is more convenient. The fixed bracket 112 and the shell body 111 in this example can be connected by snap connection or screw connection.

[0043] In an example, please refer to Figures 1 to 4 , or in combination with reference Figures 5 to 9 The shell group 110 is provided with an arc-shaped limiting groove 112a, and the center of the arc-shaped limiting groove 112a is located on the rotation axis of the rotating frame 120; the rotating frame 120 is provided with a rotating rod 130, and the extension direction of the rotating rod 130 is parallel to the rotation axis of the rotating frame 120, and the rotating rod 130 passes through the arc-shaped limiting groove 112a and can slide in the arc-shaped limiting groove 112a.

[0044] By providing the arc-shaped limit groove 112a on the shell assembly 110, and providing the rotating frame 120 with a rotating rod 130, and the rotating rod 130 passes through the arc-shaped limit groove 112a and slides in the limit groove, the rotating frame 120 can achieve the effect of being able to rotate along a stable trajectory through the cooperation of the rotating rod 130 and the arc-shaped limit groove 112a, thereby improving the effectiveness of the rotation of the rotating frame 120. In addition, by providing the arc-shaped limit groove 112a on the shell assembly 110, the provision of the arc-shaped limit groove 112a can limit the rotation angle of the rotating frame 120, so as to reduce the risk of the rotating frame 120 colliding with the shell assembly 110 or the endoscope body due to excessive rotation angle. It should be noted that, based on the solution that the shell group 110 includes the above-mentioned shell body 111 and the fixed bracket 112, the arc-shaped limit groove 112a can be provided on the fixed bracket 112, so as to achieve the effect of the rotating rod 130 passing through the arc-shaped limit groove 112a while installing the rotating bracket on the fixed bracket 112, thereby making the assembly process simple and efficient.

[0045] In an example, please refer to Figures 1 to 4 , or in combination with reference Figures 5 to 9The support assembly 100 further includes a damping assembly 140 , which is connected between the rotating frame 120 and the housing assembly 110 .

[0046] By providing a damping assembly 140 between the rotating frame 120 and the shell assembly 110, the rotating frame 120 has a certain damping effect during the rotation process, so that the rotating frame 120 can provide good support for the endoscope body after rotating to any angle, and the rotating frame 120 can stop rotating at any position, thereby widening the adjustment range of the installation angle of the endoscope host 200.

[0047] In an example, please refer to Figures 1 to 4 , or in combination with reference Figures 5 to 9 The damping assembly 140 includes a positioning sleeve 141 and a fastener 142. The positioning sleeve 141 is sleeved outside the rotating rod 130, and one side of the positioning sleeve 141 abuts against the shell group 110 in its axial direction; the fastener 142 is connected to the rotating rod 130, and abuts against the side of the positioning sleeve 141 away from the shell group 110 in the axial direction of the positioning sleeve 141.

[0048] By sleeve-arranging the positioning sleeve 141 outside the rotating rod 130, the rotating rod 130 drives the positioning sleeve 141 to rotate when it rotates with the rotating frame 120. By having one side of the positioning sleeve 141 abut against the shell group 110 in its axial direction and the other side being abutted by the fastener 142, when the positioning sleeve 141 rotates with the rotating frame 120, there is a large friction force between it and the shell group 110, thereby having a certain damping effect. With such a configuration, when the rotating frame 120 rotates to any angle, if the external force driving is removed, it can remain in the current state without continuing to rotate, thereby ensuring that it has a high stability when supporting each other with the endoscope host 200. The positioning sleeve 141 in this example can be made of elastic material or non-elastic material.

[0049] Based on the solution that the damping assembly 140 includes the positioning sleeve 141, please refer to Figures 8 to 10 The outer wall of the positioning sleeve 141 is provided with a spiral groove 141a.

[0050] By opening a spiral groove 141a on the outer wall of the positioning sleeve 141, when the fastener 142 presses against the side of the positioning sleeve 141 away from the shell group 110, the positioning sleeve 141 can undergo a certain elastic deformation, so that when the positioning sleeve 141 is pressed by the fastener 142, the positioning sleeve 141 can have a greater pressing force on the shell group 110, thereby further improving the friction between the positioning sleeve 141 and the shell group 110, so as to further increase the damping, so that after the rotating frame 120 rotates to a certain angle, it has a more stable supporting effect on the endoscope host 200.

[0051] In addition, after the spiral groove 141a is opened on the outer wall of the positioning sleeve 141, the positioning sleeve 141 has a certain elasticity in its axial direction. Therefore, the fastener 142 can be used to adjust the supporting force between the positioning sleeve 141 and the shell group 110, and then the damping between the two can be adjusted to make it more suitable for the use feel of different users.

[0052] In an example, please refer to Figures 8 to 10 The positioning sleeve 141 includes a sleeve portion 1411 and a supporting portion 1412 . The sleeve portion 1411 is sleeved outside the rotating rod 130 ; the supporting portion 1412 is protruded from the outer edge of the sleeve portion 1411 and supports the housing assembly 110 .

[0053] By protruding the supporting portion 1412 from the outer edge of the sleeve portion 1411 and supporting the shell assembly 110, the contact area between the positioning sleeve 141 and the shell assembly 110 is made larger, thereby achieving a better supporting effect and providing sufficient space for the setting of the elastic positioning protrusion 141b described below.

[0054] In an example, please refer to Figures 8 to 10 A resilient positioning protrusion 141b is provided on the side of the positioning sleeve 141 facing the shell group 110, and a plurality of positioning grooves 112b distributed in an annular shape are provided on the shell group 110. The distribution centers of the plurality of positioning grooves 112b fall on the rotating shaft of the positioning sleeve 141, and the resilient positioning protrusion 141b can be inserted into a positioning groove 112b.

[0055] With such arrangement, when the positioning sleeve 141 rotates with the rotating rod 130 and the rotating frame 120, the elastic positioning protrusion 141b on the positioning sleeve 141 can be selectively inserted into one of the positioning grooves 112b, so that the rotating frame 120 can be in a relatively stable state, and a click sound can be made to remind the user that the state of the rotating frame 120 is relatively stable in this state, and the position of the rotating frame 120 is reliable. When the rotating frame 120 continues to rotate, the elastic positioning protrusion 141b is squeezed and disengaged from the previously inserted positioning groove 112b, so as to enter the next positioning groove 112b. Before entering the next positioning groove 112b, the abutment force between the elastic positioning protrusion 141b and the shell group 110 is relatively large, thereby increasing the friction between the two, further improving the damping feeling, and enhancing the stability of the rotating frame 120 after the external force is removed.

[0056] In an example, please refer to Figures 1 to 7 One end of the rotating rod 130 is connected to the rotating frame 120 , and the other end passes through the arc-shaped limiting groove 112 a . The positioning sleeve 141 is located on a side of the arc-shaped limiting groove 112 a away from the rotating frame 120 .

[0057] By sleeve-mounting the positioning sleeve 141 on the side of the arc-shaped limiting groove 112a away from the rotating frame 120, it is convenient for the user to hold the positioning sleeve 141 against the shell assembly 110 with the arc-shaped limiting groove 112a through the fastener 142, making the assembly process of each component more convenient.

[0058] Of course, in other examples, the positioning sleeve 141 may also be located on the side of the arc-shaped limiting groove 112 a facing the rotating frame 120 , that is, the positioning sleeve 141 abuts against the side of the housing assembly 110 facing the rotating frame 120 .

[0059] Based on the solution that the positioning sleeve 141 is located on the side of the arc-shaped limiting groove 112a away from the rotating frame 120, in one example, please refer to Figure 3 , Figure 4 , Figure 7 , Figure 8 and Fig. 9 An end of the rotating rod 130 away from the rotating frame 120 is provided with an external thread, and the fastener 142 is a nut, which is threadedly connected to the external thread and abuts against a side of the positioning sleeve 141 away from the shell assembly 110.

[0060] By providing an external thread on the end of the rotating rod 130 away from the rotating frame 120 and threadably connecting the fastener 142 to the external thread, the fastener 142 can, on the one hand, limit and fix the side of the positioning sleeve 141 away from the shell group 110, and on the other hand, can also achieve the effect of adjusting the elastic expansion and contraction amount of the positioning sleeve 141. This connection method is simple and stable.

[0061] In another example, please refer to Figure 3 , Figure 4 and Figure 7 The support assembly 100 further includes a damping shaft 150 , one end of the damping shaft 150 is connected to the rotating frame 120 , and the other end is connected to the shell assembly 110 .

[0062] It should be noted that the damping shaft 150 is a component well known to those skilled in the art. One end of the damping shaft 150 is connected to the rotating frame 120, and the other end is connected to the shell assembly 110, so that the rotating frame 120 can have a certain damping force effect when rotating relative to the shell assembly 110, thereby increasing the hand feel of the user when rotating the rotating frame 120, and further enhancing the stability of the rotating frame 120 when it stops at any position. Based on the solution that the shell assembly 110 includes a shell body 111 and a fixed bracket 112, one end of the damping shaft 150 is connected to the rotating frame 120, and the other end can be connected to the fixed bracket 112.

[0063] In one example, if Figure 6As shown, the rotating frame 120 includes a connecting rod and two rotating rods, the two rotating rods are arranged opposite to each other, one end of the two rotating rods is rotatably mounted on the opposite sides of the shell group 110, and the connecting section of the connecting rod is respectively connected to the other end of the two rotating rods, and the two rotating rods and the connecting rod are enclosed together to form a gripping portion 120a. At this time, the gripping portion 120a is a handle hole structure.

[0064] In this configuration, the connecting rod of the rotating frame 120 can be used as a supporting member to support the endoscope host 200, and the rotating frame 120 itself naturally forms a hollow cavity, so that when manufacturing the rotating frame 120, the process of separately setting the gripping portion 120a can be reduced.

[0065] Based on the solution that the above-mentioned bracket assembly 100 includes a damping assembly 140 and a damping shaft 150, the above-mentioned damping assembly 140 and damping shaft 150 can be connected between each rotating rod and the shell group 110, and the two groups of damping assemblies 140 are symmetrically arranged with each other, and the two damping shafts 150 are symmetrically arranged with each other.

[0066] The utility model also provides an endoscope system, please refer to Figure 1 and Figure 5 The endoscope system includes an endoscope host 200 and a support assembly 100. The specific structure of the support assembly 100 refers to the above embodiment. Since the endoscope system adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the support assembly 100 is installed on the endoscope host 200.

[0067] By installing the support assembly 100 on the endoscope main unit 200, when the rotating frame 120 in the support assembly 100 is rotated until its gripping portion 120a is located below the rotation axis, it can serve as a supporting surface together with the bottom of the endoscope main unit 200 to support the entire endoscope main unit 200 or the endoscope system.

[0068] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
