[0002] In the related art, a lamp, a camera or the like to-be-assembled device is generally assembled to a support through a locking mechanism. The locking force of the locking mechanism is generally small. When the load of the to-be-assembled device is large, the stability of the to-be-assembled device is poor, and the to-be-assembled device is prone to relative movement, which is difficult to meet the use requirement.

[0003] In some cases, the locking force of the locking mechanism can be increased to improve the stability of the to-be-assembled device. For example, the locking mechanism includes two locking members, the two locking members are connected to the to-be-assembled device and the support respectively, and the two locking members are locked by mutual locking. By increasing the diameter of the locking member, the locking force of the locking mechanism can be increased to improve the stability of the to-be-assembled device.

[0062] Please refer to the following: Figures 1 to 7 And in conjunction with other accompanying figures.

Figure 2 This is an exploded view of the support structure 1000 provided in some embodiments of this application. Figure 3 for Figure 2 A magnified view of a portion of the image. Figure 4 This is a cross-sectional view of the support structure 1000 provided in some embodiments of this application. Figure 5 for Figure 4 A magnified view of a portion of the image. Figure 6 This is a perspective view of the first lock attachment 10 of the locking mechanism 100 provided in some embodiments of this application. Figure 7 This is a perspective view of the second locking attachment 20 of the bracket structure 1000 provided in some embodiments of this application. The locking mechanism 100 provided in the embodiments of this application is mainly used in conjunction with the bracket 200 and the device to be assembled. The device to be assembled may be a lamp, a camera, etc.

[0063] The locking mechanism 100 provided by the embodiments of the present application comprises a first locking accessory 10, a second locking accessory 20 and an adjusting assembly 30. The first locking accessory 10 is arranged on a support 200, and the second locking accessory 20 is arranged on a device to be assembled. The second locking accessory 20 is arranged along a first direction Y with the first locking accessory 10. In the first direction Y, a side of the first locking accessory 10 facing the second locking accessory 20 is provided with a plurality of first contact surfaces 101 arranged at intervals. In the first direction Y, a side of the second locking accessory 20 facing the first locking accessory 10 is provided with a plurality of second contact surfaces 201 arranged at intervals. The plurality of first contact surfaces 101 and the plurality of second contact surfaces 201 are arranged in a position corresponding manner. The second locking accessory 20 has a locked position and an unlocked position. In the locked position, the first contact surfaces 101 and the second contact surfaces 201 abut each other along the first direction Y. In the unlocked position, the first contact surfaces 101 and the second contact surfaces 201 are arranged at intervals. The adjusting assembly 30 is used to adjust the position of the second locking accessory 20 along the first direction Y, so as to switch the second locking accessory 20 between the locked position and the unlocked position, and adjust the abutting degree of the first contact surfaces 101 and the second contact surfaces 201 in the locked position.

[0064] The first locking accessory 10 can be arranged on the support 200 by means of bolt fastening, riveting or the like.

[0065] The device to be assembled can be arranged on the second locking accessory 20 by means of bolt fastening, riveting or the like.

[0066] The first locking accessory 10 and the second locking accessory 20 are two components arranged to be locked with each other. In the locked position, it can be understood that the second locking accessory 20 is in the locked position. In the unlocked position, it can be understood that the second locking accessory 20 is in the unlocked position.

[0067] The second locking accessory 20 is arranged along the first direction Y with the first locking accessory 10, which means that the first locking accessory 10 and the second locking accessory 20 are arranged along the first direction Y in a general manner, but not necessarily in an absolute manner. That is, it is allowed that part of the first locking accessory 10 and part of the second locking accessory 20 are arranged along a direction other than the first direction Y. For example, in the locked position, the first protrusion 121 and the second groove 203 are inserted and matched along the first direction Y, so that the first protrusion 121 and the second protrusion 221 are arranged along the radial direction of the screw rod 31. It can be understood that the first direction Y is the general arrangement direction of the first locking accessory 10 and the second locking accessory 20, and the first direction Y does not limit the arrangement order of the first locking accessory 10 and the second locking accessory 20, and is a double arrow direction.

[0068] The first direction Y is arranged in a general perpendicular manner with the radial direction of the screw rod 31, and the radial direction of the screw rod 31 is shown by the direction X in the drawing.

[0069] The first direction Y and the circumferential direction are substantially perpendicular to each other, and the circumferential direction is shown by the direction W in the drawings.

[0070] The first contact surface 101 is a surface of the first locking accessory 10 for abutting against the second locking accessory 20 along the first direction Y, and the second contact surface 201 is a surface of the second locking accessory 20 for abutting against the first locking accessory 10 along the first direction Y.

[0071] In the first direction Y, the side of the first locking accessory 10 facing the second locking accessory 20 is provided with a plurality of first contact surfaces 101 arranged at intervals, such that the surface area of each first contact surface 101 is smaller than the surface area of the side of the first locking accessory 10 facing the second locking accessory 20 along the first direction Y, and the sum of the surface areas of the plurality of first contact surfaces 101 is also smaller than the surface area of the side of the first locking accessory 10 facing the second locking accessory 20 along the first direction Y, so that each first contact surface 101 is a contact surface with a small surface area, which is conducive to the control of the flatness of the first contact surface 101. Correspondingly, in the first direction Y, the side of the second locking accessory 20 facing the first locking accessory 10 is provided with a plurality of second contact surfaces 201 arranged at intervals, such that the surface area of each second contact surface 201 is smaller than the surface area of the side of the second locking accessory 20 facing the first locking accessory 10 along the first direction Y, and the sum of the surface areas of the plurality of second contact surfaces 201 is also smaller than the surface area of the side of the second locking accessory 20 facing the first locking accessory 10 along the first direction Y, so that each second contact surface 201 is a contact surface with a small surface area, which is conducive to the control of the flatness of the second contact surface 201. Understandably, the first locking accessory 10 and the second locking accessory 20 are each provided with a plurality of contact surfaces with small surface areas.

[0072] In the locked position, the first contact surface 101 and the second contact surface 201 abut against each other along the first direction Y to generate an acting force, so that the first locking accessory 10 and the second locking accessory 20 are locked, thereby enabling the first locking accessory 10 and the second locking accessory 20 to be relatively stationary as much as possible, so that the device to be assembled and the bracket 200 can be relatively stationary as much as possible. In the locked position, other surfaces of the first locking accessory 10 and other surfaces of the second locking accessory 20 can be arranged at intervals or at least partially abut against each other.

[0073] In the unlocked position, the first contact surface 101 and the second contact surface 201 can be arranged at intervals along the first direction Y, so that the first locking accessory 10 and the second locking accessory 20 are unlocked, thereby enabling the first locking accessory 10 and the second locking accessory 20 to move relative to each other.

[0074] The plurality of first contact surfaces 101 and the plurality of second contact surfaces 201 are arranged in position correspondence, that is, each first contact surface 101 and each second contact surface 201 in the plurality of first contact surfaces 101 and the plurality of second contact surfaces 201 are arranged in position correspondence. In the unlocked position, each first contact surface 101 and each second contact surface 201 can be arranged in interval and relative to the first direction Y. In the locked position, each first contact surface 101 and each second contact surface 201 abut along the first direction Y.

[0075] The adjusting assembly 30 is an assembly for adjusting the position of the second locking accessory 20 in the first direction Y. The adjusting assembly 30 adjusts the position of the second locking accessory 20 in the second direction, which can achieve the adjustment of the relative position of the second locking accessory 20 and the first locking accessory 10 in the first direction Y. Through the adjusting assembly 30, the position of the second locking accessory 20 in the second direction can be adjusted from the unlocked position to the locked position, or from the locked position to the unlocked position. In the locked position, the adjusting assembly 30 adjusts the position of the second locking accessory 20 in the second direction, which can achieve the adjustment of the abutting degree of the first contact surface 101 and the second contact surface 201, that is, the adjustment of the fitting degree of the first contact surface 101 and the second contact surface 201, thereby achieving the adjustment of the locking force of the first locking accessory 10 and the second locking accessory 20.

[0076] The locking mechanism 100 provided by the embodiments of the present application is arranged in that the side of the first locking accessory 10 facing the second locking accessory 20 is provided with a plurality of first contact surfaces 101 arranged in interval, the side of the second locking accessory 20 facing the first locking accessory 10 is provided with a plurality of second contact surfaces 201 arranged in interval, the plurality of first contact surfaces 101 and the plurality of second contact surfaces 201 are arranged in position correspondence, and in the locked position, the first contact surface 101 and the second contact surface 201 abut each other. Compared with the scheme that the two locking accessories abut each other through the contact surfaces with large surface area in the locked position, the first locking accessory 10 and the second locking accessory 20 are both provided with a plurality of contact surfaces with small surface area, which is conducive to the control of the flatness of the first contact surface 101 and the second contact surface 201, so as to help improve the flatness of the first contact surface 101 and the second contact surface 201, thereby facilitating the improvement of the fitting degree of the first contact surface 101 and the second contact surface 201 in the locked position. In this way, the technical problem that the increase of the locking force of the locking mechanism 100 leads to the increase of the volume and weight can be solved, that is, the locking force of the first locking accessory 10 and the second locking accessory 20 can be improved without excessively increasing the volume and weight of the locking mechanism 100, thereby helping to improve the stability of the to-be-assembled device, so as to meet the use requirements.

[0077] In some embodiments, please refer to Figures 3 to 7, and in conjunction with other drawings. The adjusting assembly 30 comprises a screw rod 31 and an adjusting piece 32. The screw rod 31 is arranged in at least one of the first locking accessory 10 and the second locking accessory 20 along the first direction Y. The adjusting piece 32 is threadedly connected to the screw rod 31 and used to adjust the position of the second locking accessory 20 along the first direction Y when rotating relative to the screw rod 31.

[0078] It can be understood that the outer surface of the screw rod 31 is provided with external threads, and the adjusting piece 32 is provided with internal threads. The internal threads of the adjusting piece 32 are threadedly connected with the external threads of the screw rod 31. When the adjusting piece 32 rotates relative to the screw rod 31, the adjusting piece 32 will move relative to the screw rod 31 along the first direction Y. Under the limiting action of the adjusting piece 32 and the screw rod 31, the second locking accessory 20 will move along the first direction Y to achieve the position adjustment of the second locking accessory 20 along the first direction Y.

[0079] In this way, the position adjustment of the second locking accessory 20 along the first direction Y can be achieved by rotating the adjusting piece 32. This makes the switching of the second locking accessory 20 between the locked position and the unlocked position and the adjustment of the locking force of the second locking accessory 20 and the first locking accessory 10 in the locked position very simple and convenient.

[0080] In some possible designs, the first locking accessory 10 can be provided with a first through hole 102 along the first direction Y. The screw rod 31 is arranged in the first locking accessory 10 along the first direction Y, which means that the screw rod 31 is arranged in the first through hole 102 along the first direction Y.

[0081] In some possible designs, the second locking accessory 20 can be provided with a second through hole 202 along the first direction Y. The screw rod 31 is arranged in the second locking accessory 20 along the first direction Y, which means that the screw rod 31 is arranged in the second through hole 202 along the first direction Y.

[0082] In some embodiments, please refer to Figure 3 and Figure 5 , and in conjunction with other drawings. The screw rod 31 comprises a rod body 311 and a head 312. The rod body 311 and the head 312 are arranged along the first direction Y. The adjusting piece 32 is threadedly connected with the rod body 311.

[0083] It can be understood that the external threads of the screw rod 31 are arranged on the rod body 311.

[0084] The cross section of the head 312 perpendicular to the first direction Y is greater than the cross section of the rod body 311 perpendicular to the first direction Y.

[0085] In some embodiments, please refer to Figure 3 , Figures 5 to 7, and in combination with other drawings. The rod body 311 is used to be sequentially arranged in the support 200, the first locking accessory 10 and the second locking accessory 20 along the first direction Y, and the rod body 311 is rotationally stopped with the support 200.

[0086] Specifically, the support 200 is formed with a third through hole along the first direction Y. The rod body 311 is arranged in the support 200 along the first direction Y, which means that the rod body 311 is arranged in the third through hole along the first direction Y. It can be understood that the rod body 311 is sequentially arranged in the third through hole, the first through hole 102 and the second through hole 202 along the first direction Y.

[0087] The rod body 311 is rotationally stopped with the support 200, which means that the rod body 311 cannot rotate relative to the support 200 through the cooperation between the rod body 311 and the support 200, specifically, the rod body 311 cannot rotate in the third through hole. As an example, the inner circumferential wall of the third through hole is recessed to form a limiting groove, and the outer surface of the rod body 311 is formed with a protruding portion, the protruding portion and the limiting groove are recessed and protruding matched to limit the rotation of the rod body 311 in the third through hole. As another example, the cross section of the part of the rod body 311 arranged in the third through hole perpendicular to the first direction Y is non-circular, and the cross section of the third through hole perpendicular to the first direction Y is also non-circular.

[0088] In some possible designs, please refer to Figure 3 , Figures 5 to 7 , and in combination with other drawings. In the first direction Y, the head 312 is limited on the side of the second locking accessory 20 away from the first locking accessory 10. In the first direction Y, the adjusting piece 32 is used to be limited on the side of the support 200 away from the first locking accessory 10.

[0089] Based on this, when the adjusting piece 32 is rotated, the rod body 311 can move in the direction in which the second locking accessory 20 points to the first locking accessory 10 along the first direction Y under the action of the adjusting piece 32, and the adjusting piece 32 can move to the support 200 along the first direction Y under the action of the rod body 311, so that the second locking accessory 20 is close to the first locking accessory 10 along the first direction Y under the limiting action of the head 312, so that the second locking accessory 20 can be switched from the unlocking position to the locking position, or the fitting degree of the first contact surface 101 and the second contact surface 201 in the locking position can be improved.

[0090] When the adjusting piece 32 is rotated, the adjusting piece 32 can move away from the support 200 along the first direction Y, and the rod body 311 can also move in the direction in which the first locking accessory 10 points to the second locking accessory 20 along the first direction Y under the action of the adjusting piece 32, so that the first locking accessory 10 and the second locking accessory 20 are unlocked, thereby facilitating the second locking accessory 20 to be switched from the locking position to the unlocking position.

[0091] It can be understood that the rod body 311 is arranged to be movable relative to the third through hole in the first direction Y and is rotationally fixed with the third through hole.

[0092] By limiting the adjusting piece 32 on the side of the support 200 away from the first locking accessory 10 in the first direction Y, the problem that the adjusting piece 32 interferes with the device to be assembled on the second locking accessory 20 can be adjusted.

[0093] In some possible designs, the head 312 is used to limit on the side of the support 200 away from the first locking accessory 10 in the first direction Y. In the first direction Y, the adjusting piece 32 is limited on the side of the second locking accessory 20 away from the first locking accessory 10.

[0094] Therefore, when the adjusting piece 32 is rotated, the adjusting piece 32 can move towards the second locking accessory 20 in the first direction Y, so that the second locking accessory 20 is moved towards the first locking accessory 10 in the first direction Y under the limiting action of the adjusting piece 32, and thus the second locking accessory 20 can be switched from the unlocked position to the locked position or the fitting degree of the first contact surface 101 and the second contact surface 201 in the locked position is improved.

[0095] When the adjusting piece 32 is rotated, the adjusting piece 32 can move away from the second locking accessory 20 in the first direction Y, so that the first locking accessory 10 and the second locking accessory 20 are unlocked, and thus the second locking accessory 20 can be switched from the locked position to the unlocked position.

[0096] The rod body 311 can be arranged to be movable relative to the third through hole in the first direction Y and rotationally fixed with the third through hole. The rod body 311 can also be fixedly connected with the support 200 to achieve the rotationally fixed connection.

[0097] In the case that the rod body 311 is arranged to be movable relative to the third through hole in the first direction Y and rotationally fixed with the third through hole, when the adjusting piece 32 is rotated, under the action of the adjusting piece 32, the rod body 311 can move in the direction in which the first locking accessory 10 points to the second locking accessory 20 in the first direction Y, so that the head 312 moves towards the support 200 in the first direction Y, and thus the second locking accessory 20 moves towards the first locking accessory 10 in the first direction Y. When the adjusting piece 32 is rotated, under the action of the adjusting piece 32, the rod body 311 can also move in the direction in which the second locking accessory 20 points to the first locking accessory 10 in the first direction Y, so that the head 312 moves away from the support 200 in the first direction Y, and thus the second locking accessory 20 is switched to the unlocked position.

[0098] By adopting the above technical solutions, the adjusting assembly 30 has more position adjustment schemes for the second locking accessory 20 in the first direction Y, and is flexible in design and simple in structure.

[0099] In some embodiments, please refer toFigure 3 and Figure 5 The adjustment assembly 30 further comprises a first gasket structure 33, which is arranged around the outer periphery of the rod body 311 and abuts between the head 312 and the second lock accessory 20 along the first direction Y.

[0100] It can be understood that the head 312 is limited along the first direction Y on the side of the second lock accessory 20 away from the first lock accessory 10.

[0101] In some possible designs, the first gasket structure 33 can comprise a first gasket 331 having a buffering performance, which is limited along the first direction Y between the head 312 and the second lock accessory 20, so as to provide a pre-tightening force between the head 312 and the second lock accessory 20, which helps to improve the fitting degree of the first contact surface 101 and the second contact surface 201.

[0102] Here, the first gasket 331 can be arranged around the outer periphery of the head 312.

[0103] Here, the first gasket 331 can be, but is not limited to, a silica gel gasket, a rubber gasket or the like.

[0104] In some possible designs, the first gasket structure 33 can comprise a second gasket, which is limited along the first direction Y between the head 312 and the second lock accessory 20, so as to reduce the damage degree of the head 312 or the second lock accessory 20.

[0105] Here, the second gasket can be, but is not limited to, a metal gasket.

[0106] Here, in the direction in which the second lock accessory 20 points to the head 312 along the first direction Y, the second gasket and the first gasket 331 can abut in sequence, and the second gasket abuts against the second lock accessory 20, and the first gasket 331 abuts against the head 312.

[0107] In some embodiments, please refer to Figure 3 and Figure 5 The adjustment assembly 30 further comprises a second gasket structure 34, which is arranged around the outer periphery of the rod body 311 and is used to abut between the adjustment piece 32 and the bracket 200 along the first direction Y.

[0108] It can be understood that the adjustment piece 32 is limited along the first direction Y on the side of the bracket 200 away from the first lock accessory 10.

[0109] In some possible design, the second gasket structure 34 can include a third gasket 341 having a buffering performance, the third gasket 341 being located between the adjusting member 32 and the bracket 200 along the first direction Y, so that a pre-tightening force can be provided between the adjusting member 32 and the bracket 200, and the fitting degree of the first contact surface 101 and the second contact surface 201 can be improved.

[0110] The third gasket 341 can be, but is not limited to, a silica gel gasket, a rubber gasket or the like.

[0111] In some possible design, the second gasket structure 34 can include a fourth gasket 342, the fourth gasket 342 being located between the adjusting member 32 and the bracket 200 along the first direction Y, so that the damage degree of the adjusting member 32 and the bracket 200 can be reduced, and the abutting force of the adjusting member 32 can be dispersed, so that the force transmission can be realized to facilitate the abutting of the first contact surface 101 and the second contact surface 201.

[0112] The fourth gasket 342 can be, but is not limited to, a metal gasket.

[0113] In the direction in which the adjusting member 32 points to the bracket 200 along the first direction Y, the third gasket 341 and the fourth gasket 342 can abut in sequence, and the fourth gasket 342 abuts against the bracket 200, and the third gasket 341 abuts against the adjusting member 32.

[0114] By adopting the technical solution, at least one of the first gasket structure 33 and the second gasket structure 34 can provide a pre-tightening force for the locking operation of the first locking accessory 10 and the second locking accessory 20, and can realize wear protection for the locking mechanism 100.

[0115] In some embodiments, in the first direction Y, when the head 312 is used to limit the side of the bracket 200 away from the first locking accessory 10, and the adjusting member 32 is located on the side of the second locking accessory 20 away from the first locking accessory 10, the gasket structure can also abut between the head 312 and the bracket 200 and between the second locking accessory 20 and the adjusting member 32.

[0116] In some embodiments, the screw rod 31 is fixedly connected with the second locking accessory 20, and the adjusting member 32 is located on the side of the bracket 200 away from the first locking accessory 10 along the first direction Y. The screw rod 31 can pass through the second locking accessory 20 along the first direction Y or not.

[0117] The gasket structure can abut between the adjusting member 32 and the bracket 200.

[0118] In some embodiments, the screw rod 31 is fixedly connected with the bracket 200, and the adjusting member 32 is located on the side of the second locking accessory 20 away from the first locking accessory 10 along the first direction Y.

[0119] The adjusting member 32 and the second locking member 20 can abut against a gasket structure.

[0120] In some embodiments, the rod 31 is not disposed in the bracket 200, and is disposed in the first locking member 10 along the first direction Y. The head 312 is limited on a side of the first locking member 10 away from the second locking member 20 along the first direction Y, and the adjusting member 32 is limited on a side of the second locking member 20 away from the first locking member 10 along the first direction Y.

[0121] The adjusting member 32 and the second locking member 20, and the head 312 and the first locking member 10 can abut against a gasket structure.

[0122] In some embodiments, the rod 31 is not disposed in the bracket 200, and is disposed in the second locking member 20 along the first direction Y. The rod 31 and the first locking member 10 are fixedly connected, and the adjusting member 32 is limited on a side of the second locking member 20 away from the first locking member 10 along the first direction Y. The rod 31 can be disposed in the first locking member 10 along the first direction Y or not.

[0123] The adjusting member 32 and the first locking member 10 can abut against a gasket structure.

[0124] In some embodiments, the rod 31 is not disposed in the bracket 200, and is disposed in the second locking member 20 along the first direction Y. The rod 31 and the first locking member 10 are fixedly connected, and the adjusting member 32 is limited on a side of the second locking member 20 away from the first locking member 10 along the first direction Y. The rod 31 can be disposed in the first locking member 10 along the first direction Y or not.

[0125] The adjusting member 32 and the second locking member 20 can abut against a gasket structure.

[0126] In some embodiments, please refer to Figure 3 , Figures 5 to 7 , and in combination with other drawings. Each first contact surface 101 is disposed around the outer periphery of the rod 31, and a plurality of first contact surfaces 101 are disposed at intervals along the radial direction of the rod 31.

[0127] It can be understood that the plurality of first contact surfaces 101 are sequentially disposed around.

[0128] Correspondingly, each second contact surface 201 is disposed around the outer periphery of the rod 31, and a plurality of second contact surfaces 201 are disposed at intervals along the radial direction of the rod 31, so that each first contact surface 101 and each second contact surface 201 can abut along the first direction Y at the locking position.

[0129] In some embodiments, the at least part of the first contact surfaces 101 are circumferentially spaced apart to collectively surround the outer periphery of the screw 31.

[0130] It can be appreciated that the number of the at least part of the first contact surfaces 101 is plural. The number of the at least part of the second contact surfaces 201 is also plural, and the at least part of the second contact surfaces 201 are circumferentially spaced apart to collectively surround the outer periphery of the screw 31, so that each of the first contact surfaces 101 can abut against each of the second contact surfaces 201 in the first direction Y.

[0131] In some possible designs, all of the first contact surfaces 101 can be circumferentially spaced apart to collectively surround the outer periphery of the screw 31. Correspondingly, all of the second contact surfaces 201 can be circumferentially spaced apart to collectively surround the outer periphery of the screw 31.

[0132] In other possible designs, all of the first contact surfaces 101 can be divided into a plurality of portions, and the plurality of portions are distributed along the radial direction of the screw 31 in sequence, and each of the portions of the first contact surfaces 101 are circumferentially spaced apart to collectively surround the outer periphery of the screw 31. Correspondingly, all of the second contact surfaces 201 can be divided into a plurality of portions, and the plurality of portions are distributed along the radial direction of the screw 31 in sequence, and each of the portions of the second contact surfaces 201 are circumferentially spaced apart to collectively surround the outer periphery of the screw 31.

[0133] In other possible designs, all of the first contact surfaces 101 can be divided into a plurality of portions. In at least one portion, each of the portions of the first contact surfaces 101 are circumferentially spaced apart to collectively surround the outer periphery of the screw 31, and the remaining portions can be arranged in other manners. Correspondingly, all of the second contact surfaces 201 can be divided into a plurality of portions. In at least one portion, each of the portions of the second contact surfaces 201 are circumferentially spaced apart to collectively surround the outer periphery of the screw 31, and the remaining portions can be arranged in other manners. As an example, in the remaining portions of the first contact surfaces 101, each portion includes one first contact surface 101, each of the first contact surfaces 101 surrounds the outer periphery of the screw 31, and the plurality of portions are distributed along the radial direction of the screw 31 in sequence. Correspondingly, in the remaining portions of the second contact surfaces 201, each portion includes one second contact surface 201, each of the second contact surfaces 201 surrounds the outer periphery of the screw 31, and the plurality of portions are distributed along the radial direction of the screw 31 in sequence.

[0134] By using the above technical solutions, the force generated by the contact between the first contact surfaces 101 and the second contact surfaces 201 is distributed around the outer periphery of the screw 31, and the distribution is relatively uniform, which is beneficial for the first locking member 10 and the second locking member 20 to achieve stable locking, thereby helping to improve the locking force of the locking mechanism 100, and facilitating the improvement of the stability of the device to be assembled.

[0135] In some embodiments, please refer to Figure 3 , Figures 5 to 7 , and the other drawings. The first locking accessory 10 comprises a first part and a second part 12. The first part 11 is used to connect the bracket 200, and the threaded rod 31 is arranged in the first part 11 along the first direction Y. The second part 12 is connected to the outer periphery of the first part 11, and the first contact surface 101 is arranged on the side of the second part 12 facing the second locking accessory 20 along the first direction Y.

[0136] The first part 11 and the second part 12 are two parts of the first locking accessory 10 distributed along the radial direction of the threaded rod 31.

[0137] The first part 11 can be connected to the bracket 200 by means of bolting, riveting, etc.

[0138] The first part 11 is formed with the first through hole 102 through it along the first direction Y, and the threaded rod 31 is arranged in the first through hole 102 along the first direction Y.

[0139] The second part 12 is connected to the outer periphery of the first part 11, which means that the second part 12 is wrapped around the outer periphery of the first part 11 and connected to the first part 11.

[0140] It can be understood that the second locking accessory 20 comprises a third part 21 and a fourth part 22, and the fourth part 22 is connected to the outer periphery of the third part 21. The threaded rod 31 is arranged in the third part 21 along the first direction Y, and the second contact surface 201 is arranged on the side of the fourth part 22 facing the first locking accessory 10 along the first direction Y.

[0141] The third part 21 and the fourth part 22 are two parts of the second locking accessory 20 distributed along the radial direction of the threaded rod 31.

[0142] The third part 21 is formed with the second through hole 202 through it along the first direction Y, and the threaded rod 31 is arranged in the second through hole 202 along the first direction Y.

[0143] In the first direction Y, the first part 11 and the third part 21 are arranged opposite to each other, and the second part 12 and the fourth part 22 are arranged opposite to each other, so that the first contact surface 101 on the second part 12 and the second contact surface 201 on the fourth part 22 are positionally corresponding.

[0144] By adopting the above technical solution, the first contact surface 101 and the second contact surface 201 are relatively far away from the threaded rod 31 along the radial direction of the threaded rod 31, which helps to increase the size of the force arm of the acting force generated by the contact of the first contact surface 101 and the second contact surface 201, thereby helping to increase the equivalent moment, so as to improve the locking force of the first locking accessory 10 and the second locking accessory 20, and improve the stability of the device to be assembled.

[0145] In some embodiments, please refer to the following: Figure 3 , Figures 5 to 9 And in conjunction with other accompanying figures. Figure 8 for Figure 6 Enlarged view of point A in the middle. Figure 9 for Figure 7 Enlarged view at point B. In the first direction Y, the first locking accessory 10 has a first protrusion 121 and a first groove 103 on the side facing the second locking accessory 20. In the first direction Y, the second locking accessory 20 has a second protrusion 221 and a second groove 203 on the side facing the first locking accessory 10. The first protrusion 121, the first groove 103, the second protrusion 221, and the second groove 203 are all arranged around the outer periphery of the screw 31. In the radial direction of the screw 31, the first protrusion 121 and the first groove 103 are arranged alternately. In the radial direction of the screw 31, the second protrusion 221 and the second groove 203 are arranged alternately. In the first direction Y, the first protrusion 121 is used for insertion and engagement with the second groove 203. In the first direction Y, the second protrusion 221 is used for insertion and engagement with the first groove 103.

[0146] In the radial direction of the screw 31, the first protrusion 121 and the first groove 103 are arranged alternately, meaning that the first protrusion 121 and the first groove 103 are alternately arranged in a concave-convex manner in the radial direction of the screw 31. In the radial direction of the screw 31, the second protrusion 221 and the second groove 203 are arranged alternately, meaning that the second protrusion 221 and the second groove 203 are alternately arranged in a concave-convex manner in the radial direction of the screw 31.

[0147] In the first direction Y, the surface of the first protrusion 121 facing the second lock accessory 20 extends beyond the surface of the first groove 103 facing the second lock accessory 20. Similarly, in the first direction Y, the surface of the second protrusion 221 facing the first lock accessory 10 extends beyond the surface of the second groove 203 facing the first lock accessory 10.

[0148] Specifically, the first protrusion 121 and the first groove 103 are formed on the side of the second component 12 facing the second lock accessory 20 along the first direction Y. It can be understood that the second component 12 includes a first main body 122 and the aforementioned first protrusion 121. The first main body 122 is connected to the outer periphery of the first component 11, and the first protrusion 121 is provided on the side of the first main body 122 facing the second lock accessory 20 along the first direction Y.

[0149] The first groove 103 can be disposed at various positions on the side of the second component 12 facing the second lock accessory 20 along the first direction Y. For example, as Figure 6As shown, a first groove 103 may be formed between the first component 11 and the first protrusion 121 that are radially adjacent to each other along the screw 31. For example, when there are multiple first protrusions 121, the multiple first protrusions 121 are arranged at radial intervals along the screw 31, and a first groove 103 may be formed between two first protrusions 121 that are radially adjacent to each other along the screw 31.

[0150] Specifically, the second protrusion 221 and the second groove 203 are formed on the side of the fourth component 22 facing the first lock accessory 10 along the first direction Y. It can be understood that the fourth component 22 includes a second main body portion 222 and the aforementioned second protrusion 221. The second main body portion 222 is connected to the outer periphery of the third component 21, and the second protrusion 221 is provided on the side of the second main body portion 222 facing the first lock accessory 10 along the first direction Y.

[0151] The second groove 203 can be disposed at various positions on the side of the fourth component 22 facing the first lock accessory 10 along the first direction Y. For example, as Figure 7 As shown, when there are multiple second protrusions 221, the multiple second protrusions 221 are arranged radially spaced along the screw 31, and a second groove 203 can be formed between two adjacent second protrusions 221 along the radial direction of the screw 31. For example, a second groove 203 can be formed between the third component 21 and the second protrusions 221 that are adjacent along the radial direction of the screw 31.

[0152] In some possible designs, in the first direction Y, the first protrusion 121 has a first contact surface 101 on the side facing the second lock accessory 20, and the second groove 203 has a second contact surface 201 on the side facing the first lock accessory 10.

[0153] Understandably, in the first direction Y, the surface of the first protrusion 121 facing the second lock accessory 20 can be the first contact surface 101. In the first direction Y, the surface of the second groove 203 facing the first lock accessory 10 can be the second contact surface 201.

[0154] In the locked position, the first protrusion 121 is inserted into the second groove 203 along the first direction Y, and the second protrusion 221 is inserted into the first groove 103 along the first direction Y. The second contact surface 201 of the second groove 203 and the first contact surface 101 of the first protrusion 121 abut against each other along the first direction Y to generate a force.

[0155] Please refer to the following in some possible designs. Figures 5 to 7 In conjunction with other accompanying drawings, in the first direction Y, the first groove 103 has a first contact surface 101 on the side facing the second lock accessory 20, and the second protrusion 221 has a second contact surface 201 on the side facing the first lock accessory 10.

[0156] It can be understood that, in the first direction Y, the side surface of the second protrusion 221 facing the first locking accessory 10 can be the second contact surface 201. In the first direction Y, the side surface of the first groove 103 facing the second locking accessory 20 can be the first contact surface 101.

[0157] In the locked position, the first protrusion 121 is inserted into the second groove 203 in the first direction Y, the second protrusion 221 is inserted into the first groove 103 in the first direction Y, and the second contact surface 201 of the second protrusion 221 and the first contact surface 101 of the first groove 103 abut against each other in the first direction Y to generate an acting force.

[0158] It can be understood that the first protrusion 121 is formed with the first contact surface 101, the first groove 103 is not formed with the first contact surface 101, the second groove 203 is formed with the second contact surface 201, and the second protrusion 221 is not formed with the second contact surface 201. Alternatively, as shown in Figure 6 and Figure 7 the first protrusion 121 is not formed with the first contact surface 101, the first groove 103 is formed with the first contact surface 101, the second groove 203 is not formed with the second contact surface 201, and the second protrusion 221 is formed with the second contact surface 201. Alternatively, the first protrusion 121 and the first groove 103 are both formed with the first contact surface 101, and the second protrusion 221 and the second groove 203 are both formed with the second contact surface 201.

[0159] In some embodiments, please refer to Figures 5 to 7 together with other drawings. The number of the first grooves 103 and the number of the second protrusions 221 are both plural, the plural first grooves 103 are arranged at intervals in the radial direction of the screw rod 31, and the plural second protrusions 221 are arranged at intervals in the radial direction of the screw rod 31. In the first direction Y, the side of the plural first grooves 103 facing the second locking accessory 20 is provided with the first contact surface 101, and the side of the plural second protrusions 221 facing the first locking accessory 10 is provided with the second contact surface 201.

[0160] It can be understood that, in the radial direction of the screw rod 31, two adjacent first contact surfaces 101 are arranged at intervals by the first protrusion 121, and two adjacent second contact surfaces 201 are arranged at intervals by the second groove 203.

[0161] In the locked position, the first protrusion 121 is inserted into the second groove 203 along the first direction Y, the second protrusion 221 is inserted into the first groove 103 along the first direction Y, and the first contact surface 101 of the first groove 103 and the second contact surface 201 of the second protrusion 221 abut against each other along the first direction Y to generate the force. At this time, in the first direction Y, the side surface of the second groove 203 and the side surface of the first protrusion 121 can be in contact or can be spaced apart. In the radial direction of the screw rod 31, the side wall of the first protrusion 121 and the side wall of the second groove 203 can be in contact or can be spaced apart.

[0162] By spacing apart the first protrusion 121 and the second groove 203 in the locked position, the dispersion of the force at positions other than the first contact surface 101 and the second contact surface 201 can be reduced, thereby facilitating an increase in the locking force of the first locking member 10 and the second locking member 20.

[0163] In some embodiments, the number of first protrusions 121 and the number of second grooves 203 are both plural, the plurality of first protrusions 121 are spaced apart in the radial direction of the screw rod 31, and the plurality of second grooves 203 are spaced apart in the radial direction of the screw rod 31. In the first direction Y, the side of each of the plurality of first protrusions 121 facing the second locking member 20 is provided with a first contact surface 101. In the first direction Y, the side of each of the plurality of second grooves 203 facing the first locking member 10 is provided with a second contact surface 201.

[0164] It can be understood that, in the radial direction of the screw rod 31, two adjacent first contact surfaces 101 are spaced apart by a first groove 103, and two adjacent second contact surfaces 201 are spaced apart by a second protrusion 221.

[0165] In the locked position, the first protrusion 121 is inserted into the second groove 203 along the first direction Y, the second protrusion 221 is inserted into the first groove 103 along the first direction Y, and the first contact surface 101 of the first protrusion 121 and the second contact surface 201 of the second groove 203 abut against each other along the first direction Y to generate the force. At this time, in the first direction Y, the side surface of the second protrusion 221 and the side surface of the first groove 103 can be in contact or can be spaced apart. In the radial direction of the screw rod 31, the side wall of the first groove 103 and the side wall of the second protrusion 221 can be in contact or can be spaced apart.

[0166] By spacing apart the first groove 103 and the second protrusion 221 in the locked position, the dispersion of the force at positions other than the first contact surface 101 and the second contact surface 201 can be reduced, thereby facilitating an increase in the locking force of the first locking member 10 and the second locking member 20.

[0167] By adopting the technical scheme, the plurality of first contact surfaces 101 are spaced and dispersedly arranged, the plurality of second contact surfaces 201 are also spaced and dispersedly arranged, and the sum of the surface areas of the plurality of first contact surfaces 101 is small, and the sum of the surface areas of the plurality of second contact surfaces 201 is also small, which is beneficial to the control of the flatness of the plurality of first contact surfaces 101 and the plurality of second contact surfaces 201, thereby helping to improve the flatness of the first contact surface 101 and the second contact surface 201, and being beneficial to improving the fitting degree of the first contact surface 101 and the second contact surface 201 at the locked position, so as to improve the locking force of the first locking member 10 and the second locking member 20.

[0168] In some embodiments, please refer to Figure 3 , Figures 5 to 7 , and in combination with other drawings. The elastic member 40 is connected between the first locking member 10 and the second locking member 20, the elastic member 40 is spaced apart from the first contact surface 101, and the elastic member 40 is spaced apart from the second contact surface 201, and the elastic member 40 is used to apply a force to the second locking member 20 away from the first locking member 10.

[0169] Specifically, the elastic member 40 abuts between the first part 11 of the first locking member 10 and the third part 21 of the second locking member 20 along the first direction Y.

[0170] The elastic member 40 can be a spring, a spring piece, a clockwork, or the like.

[0171] By adopting the technical scheme, the elastic member 40 can be opened to the second locking member 20 along the first direction Y to move the second locking member 20 away from the first locking member 10 along the first direction Y in the process of rotating the adjusting member 32 to switch the second locking member 20 from the locked position to the unlocked position, thereby being beneficial to switching the second locking member 20 to the unlocked position.

[0172] In some embodiments, please refer to Figure 3 , Figures 5 to 7 , and in combination with other drawings. The side of the first locking member 10 facing the second locking member 20 along the first direction Y can be formed with a first counterbore 105, the side of the second locking member 20 facing the first locking member 10 along the first direction Y can be formed with a second counterbore 205, and the elastic member 40 is limited in the first counterbore 105 and the second counterbore 205. In this way, the elastic member 40 can stably provide a force to the second locking member 20.

[0173] Specifically, the first counterbore 105 is arranged on the first part 11 of the first locking member 10, and the second counterbore 205 is arranged on the third part 21 of the second locking member 20.

[0174] In some embodiments, please refer to Figures 6 to 9, and in conjunction with other drawings. The first contact surface 101 is formed with a plurality of first mesh holes 104 arranged at intervals, and the second contact surface 201 is formed with a plurality of second mesh holes 204 arranged at intervals. In the locked position, the first mesh holes 104 and the second mesh holes 204 are staggered and communicated with each other.

[0175] It can be understood that the first contact surface 101 is formed with meshed ribs so that the first contact surface 101 is formed with a plurality of first mesh holes 104. The second contact surface 201 is formed with meshed ribs so that the second contact surface 201 is formed with a plurality of second mesh holes 204.

[0176] In the locked position, the first mesh holes 104 and the second mesh holes 204 are staggered and communicated with each other, which means that in the locked position, one part of a certain first mesh hole 104 and a certain second mesh hole 204 are directly opposite and communicated, and the other part of the second mesh hole 204 is not directly opposite and communicated with the first mesh hole 104, but is directly opposite and communicated with other first mesh holes 104. In this way, the ribs on the first contact surface 101 can be matched with the second mesh holes 204, and the ribs on the second contact surface 201 can be matched with the first mesh holes 104.

[0177] In this way, the friction coefficient of the first contact surface 101 and the second contact surface 201 can be increased, so that in the locked position, the force formed by the mutual abutting of the first contact surface 101 and the second contact surface 201 can be improved, and the equivalent moment of the force formed by the mutual abutting of the first contact surface 101 and the second contact surface 201 can be improved, which helps to improve the locking force of the first locking member 10 and the second locking member 20, and to improve the stability of the device to be assembled.

[0178] In some embodiments, the first contact surface 101 is formed with a plurality of first teeth, the first teeth are arranged in a circumferential direction, and the plurality of first teeth are distributed along the radial direction of the first teeth in sequence. The second contact surface 201 is formed with a plurality of second teeth, the second teeth are arranged in a circumferential direction, and the plurality of second teeth are distributed along the radial direction of the second teeth in sequence. In the locked position, the first teeth and the second teeth are engaged with each other.

[0179] In some possible designs, each first tooth can be arranged around the outer periphery of the screw rod 31, and the radial direction of the first tooth is the radial direction of the screw rod 31. Correspondingly, each second tooth is arranged around the outer periphery of the screw rod 31, and the radial direction of the second tooth is the radial direction of the screw rod 31.

[0180] It can be understood that along the radial direction of the first teeth, a first tooth groove is formed between two adjacent first teeth, and a second tooth groove is formed between two adjacent second teeth. In the locked position, the first teeth and the second teeth are engaged with each other, which means that the first teeth are inserted into the second tooth groove in the first direction Y, and the second teeth are inserted into the first tooth groove in the first direction Y.

[0181] By setting the first teeth on the first contact surface 101 and the second teeth on the second contact surface 201, the friction coefficient of the first contact surface 101 and the second contact surface 201 can be increased. By engaging the first teeth and the second teeth with each other at the locking position, the force formed by the mutual abutting of the first contact surface 101 and the second contact surface 201 can be improved. In this way, the equivalent moment of the force formed by the mutual abutting of the first contact surface 101 and the second contact surface 201 can be improved, thereby helping to improve the locking force of the first locking member 10 and the second locking member 20, so as to improve the stability of the device to be assembled.
