[0029] In the description of the present utility model, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0030] Next, refer to Figures 1 to 6 Describe the handle mechanism according to the embodiment of the present utility model.

[0031] As Figure 1 and Figure 2As shown in the figure, the handle mechanism according to an embodiment of the present invention includes a mounting base 100, a handle 200, and an elastic ball mechanism 300. The handle 200 includes a connecting portion 210 for rotatably connecting with the mounting base 100. The elastic ball mechanism 300 is disposed on the mounting base 100 and includes a ball and an elastic member. The elastic member applies an elastic force to the ball towards the connecting portion 210, so that the ball elastically presses against the connecting portion 210.

[0032] By elastically pressing the ball against the connecting portion 210, a damping force is generated on the handle 200. When the external force applied to the handle 200 disappears, the handle 200 can be positioned at a set rotation angle through this damping force. The situation where the handle 200 drops due to its own weight is less, and it is not easy to accidentally turn outwards when the handle 200 is stored, which is convenient for the use or storage of the handle.

[0033] Specifically, since the ball is elastically pressed by the elastic member, it has a certain rolling resistance. When the connecting portion 210 abuts against the ball, the rotation of the connecting portion 210 will cause the ball to roll, thereby using the rolling resistance of the ball to form a rotational damping force on the handle 200, achieving the effect of positioning the handle 200.

[0034] It should be noted that the ideal state of the ball in the elastic ball mechanism 300 is a rollable state. When the elastic force of the elastic member is too large and the rolling resistance generated by the elastic member on the ball is greater than the sliding friction between the ball and the outer wall of the connecting portion 210, when the connecting portion 210 rotates, it does not drive the ball to rotate, and the ball slides relative to the outer wall of the connecting portion 210, which can also generate a resistance to the rotation of the handle 200, achieving the effect of positioning the handle 200.

[0035] In some embodiments of the present invention, the mounting base 100 is generally disposed on the outer shell of the device or is a part of the outer shell of the device.

[0036] In some embodiments of the present invention, the elastic ball mechanism 300 is a ball head plunger, and the mounting base 100 is disposed in a mounting groove 101 for loading the ball head plunger, so as to meet the positioning requirements of the handle 200.

[0037] Specifically, the ball head plunger includes a housing. The ball and the elastic member are both disposed in the housing. A narrow opening is provided at the upper part of the housing. The ball is elastically pressed by the elastic member to the narrow opening and partially exposed. Since the ball is elastically pressed by the elastic member, it has a certain rolling resistance.

[0038] It can be understood that in some embodiments of the present invention, a groove capable of loading the ball and the elastic member may also be provided on the mounting base 100, and an end cover is provided at the opening of the groove. A through hole for partially exposing the ball is provided on the end cover, which can also meet the effect of elastic pressing of the ball and generate a rotational resistance on the handle 200.

[0039] Such asFigure 3 , Figure 4 , Figure 5 As shown, in some embodiments of the present invention, the connecting portion 210 is provided with at least one recess 211 corresponding to the ball. When the connecting portion 210 is rotated until the recess 211 corresponds to the position of the ball, the ball can be inserted into the recess 211, thereby enhancing the positioning effect of the elastic ball mechanism 300 on the handle 200.

[0040] Specifically, under normal conditions, the connecting portion 210 presses the ball to move a certain distance, compresses the elastic member, and ensures the contact effect between the ball and the connecting portion 210, so that the connecting portion 210 can roll with the ball when rotating, thereby generating a damping force on the handle 200. When the connecting portion 210 rotates to the concave position 211 corresponding to the position of the ball, the ball can be inserted into the concave position 211, and the shape of the concave position 211 corresponds to the upper part of the ball. At this time, if the handle 200 needs to be rotated, a certain force needs to be provided to make the inner wall of the concave position 211 squeeze the ball backward. Therefore, the force required to act on the handle 200 is relatively large, that is, the handle 200 is not easy to rotate, and the positioning of the handle 200 is more stable and reliable.

[0041] like Figure 5 As shown, in some embodiments of the present invention, the connecting portion 210 is provided with three recesses 211. When the three recesses 211 cooperate with the ball bearings respectively, the handle 200 can be positioned to an angle of 0°, 45°, and 90° with the mounting base 100, thereby achieving stable positioning of the handle 200 at 0°, 45°, and 90°.

[0042] It is understandable that in some embodiments of the present invention, the recessed position 211 may also be configured to position the handle 200 at other angles, such as 30°, 60°, 120°, etc., which will not be described in detail herein.

[0043] It should be noted that, from the above discussion, it can be seen that when the ball elastically pushed by the elastic member is driven to roll by the rotation of the handle 200, it will also generate a damping force on the rotation of the handle 200, which can meet the stop positioning of the handle 200 at any angle (without setting a limiting structure); that is, in the position where the ball does not correspond to the recess 211, the elastic ball mechanism 300 can also have a certain positioning effect on the handle 200.

[0044] like Figure 2 As shown, in some embodiments of the present invention, the mounting base 100 is provided with a groove 102 corresponding to the connecting portion 210, and one side of the groove 102 is an open structure so that the handle 200 can be rotated to be flush with the mounting base 100, and the groove wall 103 on the other side of the groove 102 can resist the connecting portion 210 to limit the rotation angle of the handle 200.

[0045] Specifically, the handle 200 can rotate towards the opening side of the groove 102 until it is flush with the mounting base 100, facilitating the storage of the handle 200. The groove wall 103 on the other side of the groove 102 limits the rotation range of the handle 200. For example, the rotation angle range of the handle 200 is limited to 0° to 90° or 0° to 120°, etc.

[0046] It can be understood that in some embodiments of the present invention, both side walls of the groove 102 are provided with an open structure, enabling the handle 200 to rotate within an angle range of 0° to 180°.

[0047] Such as Figure 2 As shown, in some embodiments of the present invention, a recessed structure corresponding to the handle 200 is formed by extending the opening side of the groove 102, and the handle 200 can rotate to this recessed structure, enabling the handle 200 to be stored within the mounting base 100.

[0048] Such as Figure 6 As shown, in some embodiments of the present invention, the connecting portion 210 is provided with an abutting portion 212 that can abut against the groove wall 103 to improve the positioning effect of the abutment between the connecting portion 210 and the groove wall 103.

[0049] Specifically, the abutting portion 212 protrudes from the outer edge of the connecting portion 210 to form a raised structure. When the handle 200 is turned up to the extreme position, the abutting portion 212 abuts against the groove wall 103 first to form a limit. That is, a relatively stable positioning position can be formed by the abutment between the abutting portion 212 and the groove wall 103, avoiding the direct contact between the outer edge of the handle 200 and the groove wall 103, which may cause uncertainties in the fit, such as the influence of assembly errors, processing errors, etc., resulting in differences in the abutting positions of the handles 200 and the groove walls 103 of each product, which has a certain impact on the product quality control. At the same time, in actual production, the abutting portion 212 or its vicinity can also be thickened to improve the structural strength and reduce the occurrence of damage to the handle 200.

[0050] In some embodiments of the present invention, the abutting portion 212 is provided with a soft rubber layer to buffer the abutment between the abutting portion 212 and the groove wall 103 and slow down the impact.

[0051] Such as Figure 5 、 Figure 6As shown, in some embodiments of the present utility model, the groove wall 103 of the groove 102 can limit the handle 200 to be perpendicular to the mounting base 100. The connecting portion 210 is provided with at least one recess 211 corresponding to the ball. At least one recess 211 positions the handle 200 at an angle of 90° with respect to the mounting base 100. An extension transition groove 213 is provided on the side of the recess 211 facing the groove wall 103 that positions the handle 200 at an angle of 90° with respect to the mounting base 100. The extension transition groove 213 does not limit the ball located in the recess 211 or reduces the limiting effect on the ball located in the recess 211, that is, only the groove wall 103 limits the extreme position of the handle 200, improving the reliability of the limit.

[0052] Although both the recess 211 and the groove wall 103 can position the handle 200 in a vertical state, due to assembly or processing errors, in actual application, it is difficult for the groove wall 103 to accurately position the handle 200 at an angle of 90° with respect to the mounting base 100. For example, the groove wall 103 positions the handle 200 at an angle of 90.5° with respect to the mounting base 100, and the recess 211 is still designed at the 90° position. When people use it, they habitually turn the handle 200 up to the extreme position where it touches the groove wall 103 (at the same time, due to the application of external force, the recess 211 cannot completely position the ball). At this time, the recess 211 is misaligned with the ball, not only failing to achieve the positioning effect of the recess 211, but also causing the ball and the elastic member to be in a squeezed state for a long time, affecting the performance of the elastic member. Therefore, in the present utility model, the extension transition groove 213 has a smaller squeezing effect on the ball relative to the outer edge of the connecting portion 210. By providing the extension transition groove 213, the unilateral positioning effect of the recess 211 on the ball is cancelled or reduced, and only the groove wall 103 limits the extreme position of the handle 200, improving the reliability of the limit, and at the same time avoiding the elastic ball mechanism 300 being in a compressed state for a long time and maintaining the good performance of the elastic ball mechanism 300.

[0053] Specifically, when the handle 200 is in a vertical state, the extension transition groove 213 extends from the bottom of the recess 211 in the direction in which the handle 200 is restricted from rotating (towards the groove wall 103), thereby reducing the extrusion of the elastic ball mechanism 300 when the handle 200 rotates beyond the recess 211.

[0054] Such as Figure 5 、 Figure 6 As shown, in some embodiments of the present utility model, the surface of the connecting portion 210 in contact with the ball is an arc surface, and the recess 211 is provided on the arc surface to maintain a better abutting effect between the connecting portion 210 and the elastic ball mechanism 300.

[0055] Specifically, the center of the arc surface is approximately located on the rotation axis of the handle 200, so that the contact effect between the outer edge of the connecting portion 210 and the elastic ball mechanism 300 remains consistent.

[0056] In some embodiments of the present invention, the arc surface is provided with a soft rubber layer to increase the contact effect with the ball, so that when the connecting portion 210 rotates, it can stably drive the ball to roll and achieve the set damping effect.

[0057] Such as Figure 2 、 Figure 3 、 Figure 4 As shown in, in some embodiments of the present invention, the connecting portion 210 is installed on the mounting base 100 through a rotating shaft 220. The connecting portion 210 is provided with a shaft hole 214 through which the rotating shaft 220 can pass. The mounting base 100 is provided with a through hole 104 corresponding to the rotating shaft 220. The rotating shaft 220 can pass through the shaft hole 214 of the connecting portion 210 and the through hole 104 of the mounting base 100 and is fixed to the mounting base 100 through a fixing mechanism, thereby installing the handle 200 on the mounting base 100.

[0058] It can be understood that in some embodiments of the present invention, rotating shafts can also be extended and provided on both sides of the connecting portion 210, which can also meet the requirement of rotatable installation of the handle 200.

[0059] Such as Figure 2 、 Figure 3 、 Figure 4 As shown in, in some embodiments of the present invention, the fixing mechanism is a screw 221. The rotating shaft 220 is provided with a mounting hole 222 through which the screw 221 can pass. The mounting base 100 is provided with a threaded hole 106 that cooperates with the screw 221. The fixing of the rotating shaft 220 is completed through the cooperation of the screw 221 with the mounting hole 222 and the threaded hole 106.

[0060] It can be understood that in some embodiments of the present invention, the fixing mechanism can also be a pin mechanism, a snap mechanism, etc., which will not be elaborated here.

[0061] Such as Figure 3 、 Figure 4 As shown in, in some embodiments of the present invention, the mounting end of the rotating shaft 220 is a flat structure, and the mounting hole 222 is provided at this flat structure. Through this flat structure, the mounting stability between the mounting end of the rotating shaft 220 and the mounting base 100 can be improved.

[0062] Specifically, the mounting base 100 is provided with a receiving platform corresponding to this flat structure. The receiving platform is provided with a mounting plane corresponding to this flat structure, and the threaded hole 106 is provided at this receiving platform.

[0063] Such as Figure 3 、 Figure 4As shown, in some embodiments of the present utility model, the inner diameter of the shaft hole 214 gradually expands along the insertion direction of the rotating shaft 220, that is, the inner diameter of the end of the shaft hole 214 close to the screw 221 is larger than the inner diameter of the end far from the screw 221, so as to facilitate the installation and fixation of the rotating shaft 220.

[0064] Specifically, the inner diameter of the end of the shaft hole 214 close to the screw 221 is slightly larger than the outer diameter of the rotating shaft 220, and the inner diameter of the end of the shaft hole 214 far from the screw 221 is approximately equal to the outer diameter of the rotating shaft 220. After the rotating shaft 220 passes through the shaft hole 214 of the connecting part 210 and the through hole 104 of the mounting seat 100, the setting end of the mounting hole 222 of the rotating shaft 220 can swing within a small range, so as to facilitate the alignment of the mounting hole 222, the screw 221 and the screw 221, and facilitate the installation and fixation of the rotating shaft 220.

[0065] As Figure 2 shown, in some embodiments of the present utility model, an avoidance structure 105 capable of allowing the rotating shaft 220 to pass through is provided on the side surface of the mounting seat 100, so as to facilitate the installation of the rotating shaft 220.

[0066] As Figure 1 、 Figure 2 shown, in some embodiments of the present utility model, the handle 200 is of a U-shaped structure, and connecting parts 210 are respectively arranged at the ends of the two U-shaped arms of the handle 200, forming a handle 200 structure with double connection points, which is more stable and reliable.

[0067] In some embodiments of the present utility model, elastic ball mechanisms 300 are arranged at the installation positions corresponding to the two connecting parts 210 of the handle 200, that is, the handle 200 has a damping positioning structure, so that the handle 200 is more stable when there is no external force.

[0068] In a specific embodiment, the handle 200 is made of plastic material, and the two elastic ball mechanisms 300 can provide a rotational resistance of about 20 N for the handle 200, which can basically meet the requirement of positioning and staying at any position of the handle 200. In cooperation with the concave position 211 at the set position, the stable positioning requirement of the handle 200 at a specific position (the positioning resistance is greater than other positions) can be met, so that the handle 200 will not shift during the processes of carrying and moving the equipment.

[0069] Of course, the creation of the present utility model is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or replacements without departing from the spirit of the present utility model, and these equivalent deformations or replacements are all included in the scope defined by the claims of this application.
