Description

Technical Field

[0001] This utility model relates to the field of optical lens barrel technology, and in particular to a plastic composite optical lens barrel. Background Technology

[0002] In PCR micro-instruments, the optical tube is an important component. The optical tube is used to mount the corresponding optical parts so that the equipment can work stably.

[0003] In the existing technology, most traditional optical tubes are integral structures. When some parts are damaged, the whole thing needs to be replaced. For the remaining parts that can still function, replacing them directly will greatly increase the cost of use. Utility Model Content

[0004] The purpose of this invention is to provide a plastic composite optical tube, which solves the problem that most traditional optical tubes are integral structures. When some parts are damaged, the whole tube needs to be replaced directly. However, replacing the remaining functional parts directly would greatly increase the cost of use.

[0005] To achieve the above objectives, this utility model provides a plastic composite optical lens barrel, which is composed of four shells of the same size connected together. Each shell is provided with a main arc-shaped cavity and an auxiliary arc-shaped cavity, and the auxiliary arc-shaped cavities are symmetrically arranged on both sides of the main arc-shaped cavity. The housing is provided with vertically symmetrical connecting ears, and the connecting ears between the housings are connected by connectors; The mounting portion of the housing has multiple through holes.

[0006] Among them, the inner wall of the auxiliary arc-shaped cavity is provided with supporting semi-ring structures at intervals, and the supporting semi-ring structures are arranged in a straight line.

[0007] The housing is also provided with a semi-circular groove, which is connected to the auxiliary arc-shaped cavity.

[0008] The top of the semi-circular groove is provided with an auxiliary step and a mating part. The auxiliary step has a U-shaped structure. The mating part is located on the other side of the notch in the auxiliary step.

[0009] The housing is also provided with a weight-reducing structure, which is disposed between the mounting part and the main arc-shaped cavity.

[0010] This utility model discloses a plastic composite optical tube. The optical tube of this application is formed by connecting and assembling four shells of the same size. During subsequent use, when a part is damaged in the corresponding shell, only the damaged shell needs to be replaced. The remaining usable shells do not need to be replaced. Compared with the traditional one-piece structure, this application can replace the damaged shell separately, while the usable parts are reassembled with new shells. This solves the problem that most traditional optical tubes are one-piece structures. When a part is damaged, the whole structure needs to be replaced. However, replacing the remaining usable parts directly would greatly increase the cost of use. Attached Figure Description

Detailed Implementation

[0015] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0016] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the plastic-assembled optical lens barrel. Figure 2This is a structural diagram of the housing. This utility model provides a plastic composite optical lens barrel: the plastic composite optical lens barrel is composed of four housings 101 of identical dimensions connected together. Each housing 101 has a main arc-shaped cavity 102 and an auxiliary arc-shaped cavity 103. Connecting lugs 104 are vertically symmetrically arranged on each housing 101. Multiple through holes 106 are provided on the mounting portion of each housing 101. This solution solves the problem that traditional optical lens barrels are mostly integral structures, requiring complete replacement of the entire unit when some parts are damaged. Replacing the remaining functional parts directly would significantly increase operating costs due to the resulting scrap. Therefore, this solution can help reduce operating costs.

[0017] In this embodiment, the plastic composite optical lens barrel is composed of four housings 101 of the same size connected together. This split structure allows for direct replacement of damaged housings 101, while housings 101 that can still be used do not need to be replaced.

[0018] The housing 101 is provided with a main arc-shaped cavity 102 and an auxiliary arc-shaped cavity 103, with the auxiliary arc-shaped cavity 103 symmetrically arranged on both sides of the main arc-shaped cavity 102. After the four housings 101 are connected and assembled, the main arc-shaped cavity 102 can form a mating cavity that facilitates the installation of optical elements. Similarly, after the four housings 101 are connected and assembled, the auxiliary arc-shaped cavity 103 can facilitate the installation of mating optical elements.

[0019] The housing 101 is vertically symmetrically provided with connecting ears 104, and the connecting ears 104 between the housings 101 are connected by a connector 105; the connecting ears 104 are integrally formed with the housing 101 and are provided with through holes; the connector 105 adopts a T-shaped screw and a nut, and the optical axis end of the T-shaped screw is slidably connected with the through hole of the connecting ear 104, which serves as a positioning pin structure.

[0020] The mounting portion of the housing 101 is provided with a plurality of through holes 106. The plurality of through holes 106 facilitate the fixing of the housing 101 itself or its installation in conjunction with other components, and the through holes for fixing itself are the through holes at the two outermost ends.

[0021] Secondly, the inner wall of the auxiliary arc-shaped cavity 103 is provided with supporting semi-ring structures 107 at intervals, and the supporting semi-ring structures 107 are arranged in a straight line. After the four housings 101 are connected and assembled, the supporting semi-ring structures 107 form an integral supporting and limiting ring structure, and the corresponding working parts can be directly inserted and installed.

[0022] Then, a semi-circular groove 108 is also provided on the housing 101, and the semi-circular groove 108 communicates with the auxiliary arc-shaped cavity 103. The semi-circular groove 108 forms a circular cavity after the four housings 101 are assembled, which also facilitates the installation of auxiliary components.

[0023] Furthermore, the top of the semicircular groove 108 is provided with an auxiliary step portion 109 and a mating portion 110. The auxiliary step portion 109 has a U-shaped structure; the mating portion 110 is located on the other side of the notch in the auxiliary step portion 109. The circular cavity formed by the auxiliary step portion 109 and the semicircular groove 108 is connected and integrally formed with the housing 101. The mating portion 110 is integrally formed with the auxiliary step portion 109 and is provided with a threaded hole for mounting and fixing optical components.

[0024] Finally, a weight-reducing structure 111 is also provided on the housing 101, which is disposed between the mounting part and the main arc-shaped cavity 102. The weight-reducing structure 111 adopts a through-cavity structure and can be rectangular or other shapes, for the purpose of reducing the weight of the housing 101.

[0025] This invention addresses the problem that traditional optical barrels are mostly monolithic structures, where damage to a portion necessitates replacing the entire barrel, while replacing the remaining functional parts results in significant increased operating costs. The optical barrel of this application is assembled from four identical housings 101. During use, if a portion of a housing 101 is damaged, only the damaged portion needs to be replaced; the remaining functional housings do not require replacement. Compared to traditional monolithic structures, this invention allows for the individual replacement of damaged housings 101, while the usable parts are reassembled with new housings 101. This solves the problem of traditional optical barrels being monolithic structures, where damage to a portion necessitates replacing the entire barrel, while replacing the remaining functional parts results in significant increased operating costs.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
