Description

Technical Field

[0001] The utility model relates to the technical field of optical dust-proof protection cover processing equipment, in particular to an optical dust-proof protection cover clamping device. Background Technique

[0002] An optical dust-proof protection cover is a protection device designed to protect the mobile phone camera. It is aimed at preventing dust from falling on the lens surface and at the same time providing a certain buffering effect to reduce the damage suffered by the lens when it is knocked. When the optical dust-proof protection cover is produced and processed, it usually needs to be fixed, so a special clamping device is required.

[0003] The existing optical dust-proof protection cover clamping devices generally clamp the two outer sides of the optical dust-proof protection cover simultaneously through two groups of clamping blocks to achieve the effect of fixing it. Since the optical dust-proof protection cover used for mobile phone cameras is small in size, it is easy to deform or even break due to extrusion during clamping, which not only causes unnecessary losses, but also affects the normal processing of the optical dust-proof protection cover. Therefore, we provide an optical dust-proof protection cover clamping device. Content of the Utility Model

[0004] To solve the problem that the optical dust-proof protection cover is easily deformed or even broken due to external clamping and fixing in the above-mentioned background technique, the utility model provides an optical dust-proof protection cover clamping device.

[0005] The utility model is realized by adopting the following technical solutions: an optical dust-proof protection cover clamping device, comprising:

[0006] A base, on which a processing table is fixedly connected through a bracket;

[0007] A clamping assembly, the clamping assembly includes a lead screw rotatably connected to the bottom of the processing table through a bearing, an external thread of the lead screw is threadedly connected with a threaded sleeve, strip-shaped grooves are equidistantly circumferentially formed on the processing table, a butting rod is slidably connected inside the strip-shaped grooves, and a connecting rod is hinged between the butting rod and the threaded sleeve through a hinge member.

[0008] As a further improvement of the above solution, guide rods are symmetrically fixedly connected to the bottom of the processing table, and guide blocks are slidably connected to the outside of the guide rods and fixedly connected between the guide blocks and the threaded sleeve.

[0009] As a further improvement of the above solution, a limiting plate is fixedly connected to the bottom of the guide rod.

[0010] As a further improvement of the above solution, the width of the strip-shaped groove is smaller than the diameter of the butting rod.

[0011] As a further improvement of the above solution, a notch is provided at a position corresponding to the strip-shaped groove on the abutting rod.

[0012] As a further improvement of the above solution, an anti-slip pad is added to the outer surface of the abutting rod.

[0013] As a further improvement of the above solution, screw holes are symmetrically provided on the base, and bolts are threadedly connected inside the screw holes.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. In the process of driving the threaded sleeve threadedly connected thereto to move vertically upward by rotating the lead screw in the present utility model, by utilizing the hinged action between the threaded sleeve, the abutting rod and the connecting rod, and the sliding fit between the abutting rod and the strip-shaped groove, the abutting rod can be pushed to move outward. When the abutting rod contacts the inner side surface of the optical dust-proof protection cover, the purpose of clamping the optical dust-proof protection cover from the inner side surface can be achieved, effectively avoiding the problem that the optical dust-proof protection cover is easily deformed or even broken due to being clamped and fixed from the outside, and it has strong practicability.

[0016] 2. By clamping and fixing the optical dust-proof protection cover from the inner side surface in the present utility model, its surface can be completely exposed and unobstructed, thereby facilitating processing of its surface, and further improving the practicability of the device.

[0022] Next, in combination with the drawings and the specific embodiments, the present utility model will be further described. It should be noted that on the premise of no conflict, any combination can be formed between the following described embodiments or technical features.

[0023] Example 1:

[0024] Please refer to Figures 1-3 , a clamping device for an optical dust-proof protection cover in this embodiment, includes:

[0025] Base 1, on which a processing table 2 is fixedly connected through a bracket. Screw holes are symmetrically opened on the base 1, and bolts 3 are threadedly connected inside the screw holes, facilitating the installation and fixation of the base 1 and ensuring the stability of the device during use;

[0026] Clamping assembly. The clamping assembly includes a lead screw 101 rotatably connected to the bottom of the processing table 2 through a bearing. A threaded sleeve 102 is threadedly connected to the outside of the lead screw 101. Strip-shaped grooves 103 are equidistantly circumferentially opened on the processing table 2. A contact rod 104 is slidably connected inside the strip-shaped grooves 103. A connecting rod 105 is hinged between the contact rod 104 and the threaded sleeve 102 through a hinge member. Guide rods 106 are symmetrically fixedly connected to the bottom of the processing table 2. A guide block 107 is slidably connected to the outside of the guide rods 106 and is fixedly connected to the threaded sleeve 102, which can play a certain guiding role in the vertical movement of the threaded sleeve 102. A limit plate 108 is fixedly connected to the bottom of the guide rod 106, which can prevent the guide block 107 from separating from the guide rod 106. The width of the strip-shaped groove 103 is smaller than the diameter of the contact rod 104. A notch 109 is opened at the position of the contact rod 104 corresponding to the strip-shaped groove 103, which can play a certain guiding role in the horizontal movement of the contact rod 104.

[0027] The implementation principle of a clamping device for an optical dust-proof protection cover in an embodiment of this application is as follows: First, place the optical dust-proof protection cover upside down on the processing table 2 and make the contact rod 104 in the circular hole on the optical dust-proof protection cover. Then rotate the lead screw 101. By rotating the lead screw 101, the threaded sleeve 102 threadedly connected to it is driven to move vertically upward. Under the hinge action between the threaded sleeve 102, the contact rod 104 and the connecting rod 105, and the sliding fit between the contact rod 104 and the strip-shaped groove 103, the contact rod 104 can be pushed to move outward. When the contact rod 104 contacts the inner side surface of the circular hole of the optical dust-proof protection cover, the purpose of clamping the optical dust-proof protection cover from the inner side surface can be achieved, effectively avoiding the problem that when clamping and fixing the optical dust-proof protection cover from the outside, it is easily deformed or even cracked due to extrusion. At the same time, by clamping and fixing the optical dust-proof protection cover from the inner side surface, its surface can be completely exposed and unobstructed, thus facilitating processing of its surface. Finally, after processing is completed, release the optical dust-proof protection cover and take it away.

[0028] Example 2:

[0029] On the basis of Embodiment 1, the further improvement of this embodiment lies in that: an anti-slip pad is added to the outer surface of the abutting rod 104, which can increase the friction between the abutting rod 104 and the optical dust-proof protection cover, so as to improve the clamping and fixing effect on the optical dust-proof protection cover.

[0030] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and the scope of protection of the present invention cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
