Description

Technical Field

[0001] The utility model belongs to the technical field of optical devices, and in particular relates to a rotary pull rod structure of an optical device. Background Art

[0002] A pull rod for unlocking the module is provided on the housing of the optical device. The pull rod is located on the side of the housing facing the optical fiber, and the end of the pull rod extends toward one side of the optical fiber. Therefore, during the process of plugging and unplugging the optical fiber, the pull rod will block the operating space of the hands. In order to solve the above problems, the utility model patent with authorization announcement number CN221124934U discloses a rotating pull rod structure of the optical device, including a housing and a pull rod. The housing is provided with a mounting hole, and a rotating shaft is provided in the mounting hole. The pull rod is rotatably connected to the housing through the rotating shaft. The utility model is provided with a pull rod that can rotate relative to the housing. The pull rod can be rotated before plugging and unplugging the optical fiber to adjust the position of the pull rod, thereby avoiding the pull rod from blocking the fingers when plugging and unplugging the optical fiber.

[0003] However, the above mechanism has the following problems: the pull rod structure is connected to the shell only through the rotating shaft of the steel wire structure. Therefore, during the process of pushing and pulling the pull rod, the force-bearing point structure of the pull rod and the shell is weak and prone to breakage. In addition, during the process of pushing and pulling the pull rod, the pushing and pulling force easily causes the pull rod to rotate relative to the shell, affecting the normal operation of the pull rod. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a rotatable pull rod structure for an optical device, so as to solve the problem that the stress point structure of the existing rotatable pull rod and the shell is weak and prone to breakage and detachment. In addition, during the process of pushing and pulling the pull rod, the pushing and pulling force easily causes the pull rod to rotate relative to the shell, affecting the normal operation of the pull rod.

[0005] To achieve the above objectives, the utility model adopts a technical solution: a rotating pull rod structure of an optical device, comprising a shell, the front end of the shell is rotatably connected to a pull rod through a rotating shaft, both sides of the pull rod are connected to clamping plates, the clamping plates are composed of side plates, a connecting section and a clamping ring, both sides of the shell are connected to clamping blocks, and the clamping blocks are adapted to clamp the clamping rings.

[0006] The beneficial effect of the utility model is that when the pull rod rotates to be parallel to the shell, the clamping ring can produce elastic deformation and then be clamped on the outside of the clamping block. The clamping and matching rotating shaft of the clamping block and the clamping plate can stably connect the pull rod and the shell, thereby improving the connection strength between the rotatable pull rod and the shell.

[0007] In order to enable the clamping ring to be smoothly clamped with the clamping block;

[0008] As a further improvement of the above technical solution: the axes of the clamping block and the clamping ring are on the same circle, and the axis of the circle is collinear with the axis of the rotating shaft. The open end of the clamping ring is arranged towards the clamping block.

[0009] The beneficial effect of this improvement is that during the rotation of the pull rod to be parallel to the housing, the clamping ring can smoothly clamp the clamping block.

[0010] To ensure the stability of the connection between the clamping ring and the clamping block;

[0011] As a further improvement of the above technical solution: the width of the open end of the clamping ring is not greater than the diameter of the clamping block.

[0012] The beneficial effect of this improvement is that after the clamping ring is elastically clamped outside the clamping block, it is not easy to disengage from the clamping block, thereby stably improving the connection strength between the clamping ring and the clamping block.

[0013] To ensure the stability of the connection between the clamping ring and the clamping block;

[0014] As a further improvement of the above technical solution: the inner diameter of the clamping ring is the same as the diameter of the clamping block.

[0015] The beneficial effect of this improvement is that the clamping ring can be stably clamped outside the clamping block.

[0016] To further improve the limiting effect of the clamping block;

[0017] As a further improvement of the above technical solution: the clamping block is a stepped cylindrical structure.

[0018] The beneficial effect of this improvement is that after the clamping ring is clamped on the surface of the narrower cylinder of the clamping block, the wider cylinder of the clamping block plays a role in limiting the clamping plate in the axial direction, further improving the connection stability between the pull rod and the housing.

[0019] To ensure the connection stability between the clamping plate and the pull rod;

[0020] As a further improvement of the above technical solution: the side plates are formed on both sides of the pull rod, and the two ends of the connecting section are respectively connected to the side plates and the clamping ring.

[0021] The beneficial effect of this improvement is that the clamping plate is stably arranged on both sides of the pull rod, and together with the clamping block, it provides stable connection support for the pull rod.

[0022] The parts not involved in this device are the same as the prior art or can be implemented using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0028] Embodiment 1:

[0029] As shown in Figure 1 —3: The rotary pull rod structure of the optical device includes a housing 1. The front end of the housing 1 is rotatably connected to a pull rod 3 through a rotating shaft 2. Clamping plates 5 are connected to both sides of the pull rod 3. The clamping plate 5 is composed of a side plate 51, a connecting section 52 and a clamping ring 53. Clamping blocks 4 are connected to both sides of the housing 1. The clamping block 4 is adapted to clamp the clamping ring 53. When the pull rod 3 rotates to be parallel to the housing 1, the clamping ring 53 can be elastically deformed and then clamped outside the clamping block 4. Through the clamping cooperation between the clamping block 4 and the clamping plate 5, the rotating shaft 2 enables the pull rod 3 to be stably connected to the housing 1, thereby improving the connection strength between the rotatable pull rod 3 and the housing 1. The axes of the clamping block 4 and the clamping ring 53 are on the same circle, and the axis of the circle is collinear with the axis of the rotating shaft 2. The open end of the clamping ring 53 is arranged towards the direction of the clamping block 4. During the process of the pull rod 3 rotating to be parallel to the housing 1, the clamping ring 53 can be smoothly clamped to the clamping block 4. The width of the open end of the clamping ring 53 is not greater than the diameter of the clamping block 4. After the clamping ring 53 is elastically clamped outside the clamping block 4, it is not easy to disengage from the clamping block 4, thereby stably improving the connection strength between the clamping ring 53 and the clamping block 4. The inner diameter of the clamping ring 53 is the same as the diameter of the clamping block 4, and the clamping ring 53 can be stably clamped outside the clamping block 4. The clamping block 4 is a stepped cylindrical structure. After the clamping ring 53 is clamped on the narrower cylindrical surface of the clamping block 4, the wider cylinder of the clamping block 4 plays a role in limiting the clamping plate 5 in the axial direction, further improving the connection stability between the pull rod 3 and the housing 1. The side plates 51 are formed on both sides of the pull rod 3. The two ends of the connecting section 52 are respectively connected to the side plate 51 and the clamping ring 53. The clamping plate 5 is stably arranged on both sides of the pull rod 3, and cooperates with the clamping block 4 to provide stable connection support for the pull rod 3.

[0030] The working principle of this technical solution is as follows: The fiber optic jumper is connected and fixed to the housing 1 by means of the clamping method of the existing technology. Before pushing the fiber optic jumper connector to move, the pull rod 3 can be rotated. The pull rod 3 can be rotated to avoid the pull rod 3 blocking the finger from pushing the jumper connector. When the pull rod 3 is rotated, the clamping ring 53 undergoes elastic deformation and disengages from the clamping block 4, enabling the pull rod 3 to rotate smoothly under the support of the rotating shaft 2. When it is necessary to fix the angle of the pull rod 3 to improve the structural stability of the pull rod 3 when it is linearly pushed or pulled, the clamping ring 53 is elastically clamped outside the clamping block 4, so that the pull rod 3 is limited by both the rotating shaft 2 and the clamping block 4, ensuring the connection strength between the pull rod 3 and the housing 1.
