When the mounting device 1 needs to be disassembled, an external force is applied to the pressing piece 13 to enable the pressing piece 13 to slide towards one side close to the elastic rod 14, namely, slide along the arrow a direction in fig. 5, namely, the pressing piece 13 slides towards the inner side of the mounting seat 11, the pressing piece 13 drives the elastic rod 14 to be separated from the shaft hole 11a, the elastic rod 14 is separated from the rotating shaft 21, namely, the elastic rod 14 loses the limiting effect on the rotating shaft 21, and the mounting device 1 can axially move relative to the rotating shaft 21. In the case of assembly, the rotating shaft 21 is inserted into the shaft hole 11a, the elastic rod 14 is far away from the shaft hole 11a under the expansion and extrusion of the rotating shaft 21, and when the rotating shaft 21 moves to a proper position, the elastic rod 14 enters the shaft hole 11a under the elastic action of the elastic rod 14 to limit the rotating shaft 21. Therefore, the mounting device 1 of the embodiment of the application has simple and convenient disassembly process and assembly process.

The specific structural form of the positioning cylinder 12 is not limited as long as it can facilitate the formation of the shaft hole 11a in the inside thereof. The axial direction of the positioning cylinder 12 is the same as that of the shaft hole 11 a. The circumferential surface of the positioning body 12 refers to a surface other than the end surface in the axial direction of the shaft hole 11a, and the specific position is not limited as long as it can be facilitated that the elastic rod 14 can be snapped into the through groove 12a from one lateral side of the positioning body 12.

The structure of the mount 11 is not limited as long as the mounting space 11c can be provided. In the embodiment of the present application, referring to fig. 1, the mounting seat 11 includes a base 110 and a skirt 112 protruding from an edge of the base 110, the base 110 and the skirt 112 together enclose the mounting space 11c, wherein the mounting hole 11b penetrates through the skirt 112, and the shaft hole 11a penetrates through the base 110. That is, in the embodiment of the present application, the extending direction of the mounting hole 11b is substantially perpendicular to the extending direction of the shaft hole 11a, thus facilitating the mounting arrangement of the pressing piece 13.

For example, in order to facilitate the assembly of the structure of the mounting device 1 itself, the side of the mounting space 11c is open, in particular, the side of the mounting space 11c facing away from the base body 110.

The shape of the mounting hole 11b and the shape of the pressing piece 13 are matched so that the pressing piece 13 can slide relatively smoothly in the mounting hole 11 b. In order to facilitate the abutment between the pressing piece 13 and the elastic rod 14, referring to fig. 4 and 5, an inclined guide surface 13a is formed at one end of the pressing piece 13 close to the elastic rod 14, and one end of the elastic rod 14 abuts against the inclined guide surface 13 a. The pressing piece 13 is under the condition of no external force action, namely under the condition of not being pressed, the elastic rod 14 is abutted against the inclined guide surface 13a under the action of self elastic force; when an external force acts on the pressing piece 13, during the sliding process of the pressing piece 13 towards the inner side of the mounting seat 11, the inclined guide surface 13a continuously pushes the elastic rod 14 to displace towards the direction away from the shaft hole 11a, and finally the elastic rod 14 is separated from the shaft hole 11a, and then after the external force is removed, the elastic rod 14 drives the pressing piece 13 to reset to the initial position under the action of the elastic force of the elastic rod 14.

Referring to fig. 4, in the embodiment of the present application, the pressing member 13 includes a pressing body 131 and a limiting portion 132, the pressing body 131 is slidably disposed in the mounting hole 11b, and the inclined guide surface 13a is formed on the pressing body 131. The limiting portion 132 protrudes from the surface of the pressing body 131, the limiting portion 132 can limit the pressing body 131, and the limiting portion 132 can abut against the inner side of the skirt portion 112 facing the installation space 11c, that is, when the pressing piece 13 slides to a certain position toward the outer side of the installation seat 11, the limiting portion 132 can abut against the inner side of the skirt portion 112, so that the pressing piece 13 cannot continuously slide outward, and the pressing piece 13 is prevented from being separated from the installation seat 11.

The shape of the stopper 132 is not limited as long as it can perform a stopper function. Referring to fig. 4, in the embodiment of the present application, the limiting portion 132 is substantially plate-shaped, so as to better adhere to the inner surface of the base 110, so as to increase the sliding stability of the pressing body 131, and further, the size of the mounting device along the axial direction of the shaft hole 11a is not additionally increased, so that the mounting device is compact in structure.

It is understood that the number of the inclined guide surfaces 13a is at least one when the number of the elastic rods 14 is one, and the number of the inclined guide surfaces 13a is at least two when the number of the elastic rods 14 is two.

Referring to fig. 4, in the embodiment of the present application, the pressing member 13 further includes a plate 133, the plate 133 extends from an edge of a side of the pressing body 131 away from the mounting hole 11b toward the positioning cylinder 12, a thickness of the plate 133 is smaller than a thickness of the pressing body 131, and a part of the structure of the elastic rod 14 is located between the plate 133 and the base 110. The plate 133 and the base 110 limit the movement of the elastic rod 14, and prevent the elastic rod 14 from swinging along the axial direction of the shaft hole 11a, so that the elastic rod 14 can move smoothly in a plane parallel to the base 110, and the movement reliability of the elastic rod 14 can be improved.

Referring to fig. 4, in an embodiment of the present application, a guide groove 13b is formed on one of a surface of the pressing member 13 close to the base 110 and a surface of the base 110 facing the pressing member 13, and a rib (not shown) slidably engaged with the guide groove 13b is formed on the other surface, and the engagement between the guide groove 13b and the rib can provide a better guiding function for the sliding of the pressing member 13.

Referring to fig. 1, the mounting device 1 according to the embodiment of the present application further includes two guide blocks 16 disposed at intervals, the guide blocks 16 are connected to the mounting base 11, specifically, the guide blocks 16 are connected to the base 110, the pressing member 13 is located between the two guide blocks 16, and the two guide blocks 16 guide the sliding of the pressing member 13, so as to further prevent the pressing member 13 from swinging away from the sliding direction during the sliding process.

It is understood that the mounting means may be selected from the above-described guide block 16 and guide groove 13b and rib, or both.

Referring to fig. 4, an arc structure 141 is formed at an end of the elastic rod 14 facing the pressing member 13, the arc structure 141 is bent in a direction away from the pressing member 13, that is, a curvature center of the arc structure 141 and the pressing member 13 are located at opposite sides of the arc structure 141, the elastic rod 14 abuts against the pressing member 13 through the arc structure 141, so that the elastic rod 14 and the pressing member 13 can be in smooth point contact, and an end of the elastic rod 14 does not directly contact with the pressing member 13, thereby reducing a probability of a clamping stagnation phenomenon occurring during a mutual movement process between the elastic rod 14 and the pressing member 13.

In the embodiment of the present application, the number of the elastic rods 14 is two, first ends of the two elastic rods 14, which are far away from the pressing member 13, are fixedly connected, second ends of the two elastic rods 14, which are close to the pressing member 13, are spaced from each other, and one end of the pressing member 13, which is close to the elastic rod 14, is clamped between the two elastic rods 14. The pressing member 13 is formed with at least two inclined guide surfaces 13a, and each of the elastic rods 14 corresponds to at least one inclined guide surface 13 a. In the process that the pressing piece 13 slides towards the elastic rods 14, the pressing piece 13 is gradually wedged between the two elastic rods 14, so that the distance between the second ends of the two elastic rods 14 is gradually enlarged until the two elastic rods 14 are separated from the shaft hole 11a, in the process, the reaction component forces of the two elastic rods 14 on the pressing piece 13 in the direction perpendicular to the sliding direction are basically equal in magnitude and opposite in direction, and therefore the probability of the transverse deflection of the pressing piece 13 can be reduced, and the sliding stability of the pressing piece 13 is improved. Further, when the external force is removed, the two elastic rods 14 jointly apply a force to the pressing piece 13 to slide in the outward direction in the axial direction of the mounting hole 11b, and the reliability of the return of the pressing piece 13 can be increased.

In order to provide the two elastic rods 14 with better structural strength and better elasticity, the two elastic rods 14 are of an integrally formed structure. Referring to fig. 1, the first end of the elastic rod 14 is formed with a smooth transition structure 142, and the transition structures 142 of the two elastic rods 14 are connected together, so as to avoid forming a sharp corner and prevent stress concentration from reducing the structural strength. The two elastic rods 14 may be made of plastic or metal.

It can be understood that one end of the elastic rod 14 facing the pressing member 13 is a movable end, i.e. the elastic rod 14 can move under the driving of the pressing member 13, and the other end of the elastic rod 14 is a fixed end, i.e. the elastic rod 14 needs to be installed and positioned, so that the elastic rod 14 can perform elastic deformation to generate elastic force.

Referring to fig. 1, the mounting device 1 further includes a fixing unit 15, the fixing unit 15 is connected to the mounting base 11, and specifically, in this embodiment, the fixing unit 15 is connected to the base 110. The first ends of the two elastic rods 14 are fixedly connected with the fixing unit 15. It should be noted that, the first ends of the two elastic rods 14 are fixedly connected with the fixing unit 15, which means that there is no relative displacement between the first ends of the elastic rods 14 and the fixing unit 15, and the fixing unit 15 can play a role in positioning the first ends of the elastic rods 14.

With reference to fig. 1, the fixing unit 15 includes a first fixing element 151 and a second fixing element 152, the second fixing element 152 is disposed on a side of the first fixing element 151 close to the elastic rod 14, and the first fixing element 151 and the second fixing element 152 are clamped on two opposite sides of the transition structure 142.

Referring to fig. 1, the first fixing member 151 is substantially in the shape of an arc plate bending toward one side of the elastic rod 14, and the shape of the side of the first fixing member 151 facing the elastic rod 14 is matched with the transition structure 142 of the two elastic rods 14, specifically, in the projection of the pressing member 13 in the sliding direction, the transition structure 142 is located within the range of the first fixing member 151, so that, when the two elastic rods 14 are expanded under the driving of the pressing member 13, the inner side of the first fixing member 151 facing the elastic rod 14 blocks the transition structure 142, thereby preventing the transition structure 142 from being excessively deformed to cause structural damage, and protecting the structure of the elastic rod 14.

The second fixing element 152 includes a fixing portion 1521 and supporting portions 1522 protruding from two opposite sides of the fixing portion 1521, the fixing portion 1521 is located between the two elastic rods 14, the thickness of the supporting portions 1522 is smaller than that of the fixing portion 1521, and the elastic rods 14 are located on one side of the supporting portions 1522 away from the base 110. The fixing portion 1521 can support the first ends of the two elastic rods 14, and the supporting portion 1522 can position the first ends of the two elastic rods 14 to prevent the two elastic rods 14 from swinging towards the base 110.
