Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, the present invention provides a camera module, a hoisting bracket 100 and a threaded connection socket 200. The camera module includes a hoisting bracket 100 and a camera (not shown) mounted on the hoisting bracket 100. The camera module is used in the fields of video monitoring, internet of things and the like, and the hoisting support 100 enables the camera to be hoisted.

Referring to fig. 2 and 3, the hoisting bracket 100 of the preferred embodiment of the present invention includes a threaded connection seat 200 and a connection rod 120. The threaded connection socket 200 includes a base 110, a threaded sleeve 130 and an axial acting element 140.

The base 110 is used for mounting to a wall or other support structure and is typically made of metal. The base 110 has a mounting hole 111, and an inner wall of the mounting hole 111 is provided with an internal thread. Therefore, the connection rod 120 may be screw-coupled with the base 110.

Specifically, in the present embodiment, the base 110 has a disk-shaped mounting plate 112, a cylindrical structure 113 is formed in the middle of the mounting plate 112, and the mounting hole 111 is formed in the cylindrical structure 113. Furthermore, the mounting plate 112 is provided with a plurality of fixing holes (not shown) along the circumferential direction of the cylindrical structure 113, so as to be matched with the threaded fasteners to stably mount the base 110 on a wall surface or other supporting members.

The connecting rod 120 is provided at one end with an external thread. The region of the connecting rod 120 where the external thread is provided is referred to as a threaded region (not shown), and the region where the external thread is not provided is referred to as a polished rod region (not shown). The connecting rod 120 is inserted into the mounting hole 111, and the external thread of the connecting rod 120 is screwed with the internal thread of the mounting hole 111, so as to realize the threaded connection between the connecting rod 120 and the base 110.

The connecting rod 120 is a long rod, and the polished rod area can be a round rod or a square rod, but is generally cylindrical. The connecting rod 120 may be solid, hollow, or partially hollow. However, to save cost, reduce mass, and facilitate routing, the connecting rod 120 is generally a hollow tubular structure. The camera is mounted at an end of the connecting rod 120 remote from the base 110. For convenience of installation, in this embodiment, a camera adapter 121 is disposed at an end of the connecting rod 120 away from the base 110.

The threaded sleeve 130 is installed in the base 110. The threaded sleeve 130 is sleeved on the connecting rod 120 and is screwed with the external thread of the connecting rod 120. Thus, the threaded sleeve 130 is fixed to the connecting rod 120. The threaded sleeve 130 may be a ring or a shaped ring, and is typically made of metal. The inner wall of the threaded sleeve 130 is provided with internal threads to engage the threaded region of the connecting rod 120.

In this embodiment, the connecting rod 120 is cylindrical, and the diameter of the polished rod region is greater than that of the threaded region, and the threaded sleeve 130 is sleeved on the threaded region and abuts against the polished rod region. Therefore, when the threaded region of the connecting rod 120 is screwed with the internal thread of the mounting hole 111 and is continuously tightened, the threaded sleeve 130 may be clamped between the hole wall of the mounting hole 111 and the polished rod region, thereby making the installation of the threaded sleeve 130 more stable.

In this embodiment, the mounting hole 111 is a stepped hole having a large hole 1112 and a small hole 1114 communicating with each other, an inner wall of the small hole 1114 is provided with an internal thread, and the threaded sleeve 130 is accommodated in the large hole 1112.

Specifically, the external threads of the connecting rod 120 are threadedly engaged with the internal threads of the aperture 114. The threaded sleeve 130 is received in the large hole 1112, so that the threaded sleeve can be mounted in a concealed manner, and the overall appearance of the hoisting bracket 100 can be improved.

The axial acting member 140 acts on the threaded sleeve 130 and the base 110, and applies a force to the threaded sleeve 130 in the direction along the central axis of the mounting hole 111. Specifically, since the extending direction of the tie bar 120 coincides with the central axis direction of the mounting hole 111, the urging direction of the axial direction acting element 140 coincides with the axial direction of the tie bar. Further, since the threaded sleeve 130 is fixed integrally with the tie rod 120, the urging force of the axial effector 140 on the threaded sleeve 130 can also act on the tie rod 120. The direction of the force is along the axial direction of the connecting rod 120, and the force can be directed to the base 110 or away from the base 110.

This axial force increases the axial pressure between the external threads of the connecting rod 120 and the internal threads of the mounting hole 111, thereby increasing the frictional force therebetween. After the friction force is increased, relative sliding is not easy to generate between the external thread of the connecting rod 120 and the internal thread of the mounting hole 111, so that the anti-loosening effect is achieved. Further, since the axial acting member 140 does not directly act on the tie bar 120, it does not press the external thread and the sidewall of the tie bar 120 from the side. Therefore, the side wall and the external thread of the tie bar 120 are not easily damaged.

There are various ways of implementing the axial acting element 140. For example, in the present embodiment, the axial acting element 140 is a locking screw, a through hole 131 extending along the axial direction of the connecting rod 120 is formed on the side wall of the threaded sleeve 130, and the locking screw is inserted into the through hole 131 and screwed or abutted with the hole wall of the mounting hole 111.

Specifically, the locking screw is screwed or pressed against the wall of the mounting hole 111, so that the base 110 and the threaded sleeve 140 interact with each other to provide an axial force to the threaded sleeve 140. Moreover, the locking screw can not only provide axial acting force, but also limit the threaded sleeve 140 in the circumferential direction and the radial direction, thereby further improving the anti-loosening effect.

Further, in the present embodiment, a locking screw hole 1116 is formed in a position of the hole wall of the mounting hole 111 corresponding to the through hole 131, and the locking screw passes through the through hole 131 and is screwed with the locking screw hole 1116.

Specifically, the through hole 131 may be a screw hole or a through hole. The locking screw is engaged with the locking screw hole 1116 to generate a pulling force, which presses the threaded sleeve 130 to generate a tight force with the base 110. At this time, the direction of the axial force applied by the axial force acting member 140 is directed toward the base 110.

In this embodiment, the sidewall of the threaded sleeve 130 forms an outwardly protruding flange 133, and the perforations 131 are located on the flange 133. The edge of the opening of the large hole 1112 is recessed to form a catch 1118, and the flange 133 is received in the catch 1118.

In particular, the threaded sleeve 130 may be a profile nut. The flange 133 may be a protruding plate-like structure or a lug structure. The perforations 131 are made in the flange 133, which on the one hand avoids the perforation of the side wall of the threaded sleeve 130 axially through it, and thus reduces the mechanical strength of the threaded sleeve 130. On the other hand, the flange 133 and the clamping groove 1118 form circumferential limitation, so that the threaded sleeve 130 can be prevented from rotating in the stepped hole, and the anti-loosening effect is further improved.

Further, in the present embodiment, the end surface of the threaded sleeve 130 abuts against the step of the stepped hole. At this time, the step may form a support to the threaded sleeve 130 so that the threaded sleeve 130 remains stable.

The assembly process of the hoisting bracket 100 in the above embodiment is as follows:

a locking screw is passed through the through hole 131 and screwed into the locking screw hole 1116 to connect but unlock the base 110 with the threaded sleeve 130; screwing the threaded region of the connecting rod 120 into the threaded sleeve 130 and continuing to screw into the small hole 1114 of the stepped bore after the threaded region of the connecting rod 120 is screwed out of the threaded sleeve 130; continuing to screw in the connecting rod 120 until the threaded sleeve 130 is pushed into the stepped hole and the end face of the threaded sleeve 130 is in contact with the step of the stepped hole; finally, the locking screw is tightened.

It can also be: the threaded area of the connecting rod 120 is first screwed into the threaded sleeve 130 and the threaded area is made to pass through the threaded sleeve 130; then the threaded region of the connecting rod 120 is screwed into the internal threads of the stepped bore hole 1114; the threaded sleeve 130 is adjusted by rotating to align with the stepped hole of the base 110, and the threaded sleeve 130 can be pushed into the stepped hole of the base 110 by continuously screwing the connecting rod 120, so that the end surface of the threaded sleeve is in contact with the step of the stepped hole; finally, the locking screw is tightened.

It should be noted that there may be a certain clearance between the end face of the threaded sleeve 130 and the step of the stepped bore, and the base 110 and the threaded sleeve 130 interact directly through the locking screw.

Referring to fig. 4 and 5, in another embodiment, the through hole 131 is a screw hole, and the locking screw is screwed into the through hole 131 and abuts against the wall of the mounting hole 111. This embodiment differs from the previous embodiment in that: the wall of the mounting hole 111 is not provided with a screw hole corresponding to the through hole 131.

Specifically, the locking screw is screwed with the through hole 131, which is a screw hole, so that the locking screw and the threaded sleeve 130 are held to each other. Further, the locking screw generates a pushing force by abutting against the wall of the mounting hole 111, and the pushing force tends to separate the threaded sleeve 130 from the base 110. At this time, the direction of the axial force applied by the axial acting member 140 is directed away from the base 110.

In this embodiment, the locking screw is forced into engagement with the threaded sleeve 130 by a threaded tightening action, so that compression of the screw head is not required. Thus, in this embodiment, the locking screw is a countersunk screw or a headless screw. At this time, the hidden installation of the locking screw can be realized in a structure with smaller size, the appearance is further improved, and meanwhile, the material cost can be saved.

The locking screw (axial acting member 140) shown in fig. 1 to 5 is only one. Obviously, a plurality of locking screws may be provided along the circumference of the threaded sleeve 130.

It is noted that the axial acting element 140 is not limited to the implementation in the above two embodiments. For example, in other embodiments, the axial acting element 140 may also be an elastic stud disposed on a step of a stepped bore. When the connecting rod 120 is screwed with the base 110 and tightened, the threaded sleeve 130 may compress the elastic boss. At this time, the elastic protruding pillar exerts an axial acting force on the threaded sleeve 130 in a direction away from the base 110, and the axial acting force also acts to increase the friction between the external thread of the connecting rod 120 and the internal thread of the mounting hole 111.

The camera module 10 is hoisted by matching the threaded connection base 200 with the connecting rod 120. The axial acting member 140 applies a force to the threaded sleeve 130 in the direction of the central axis of the mounting hole 111, the direction of the force being the same as the axial direction of the tie rod, so that the axial pressure between the external thread of the tie rod 120 and the internal thread of the mounting hole 111 is increased, and the friction between the two is increased. The friction force is increased, so that the relative sliding between the external thread of the connecting rod 120 and the internal thread of the mounting hole 111 is not easy to generate, thereby playing a role in preventing looseness. The axial force acting for preventing looseness does not directly press the external thread and the side wall of the connecting rod 120 from the side. Therefore, the threaded connection base 200 and the connecting rod 120 cannot be damaged by the side wall and the external threads when being matched, so that the reliability of the camera module is effectively improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
