Description

Technical Field

[0001] This utility model relates to the field of pressure-holding cap technology, specifically a thickened pressure-holding cap. Background Technology

[0002] With the advancement of science and technology, mobile robots are being used more and more widely. Robot communication methods include wireless and wired communication, with wireless communication being the most common. However, wired communication is still necessary in complex electromagnetic environments such as underwater, in the field, and underground in mines. Fiber optic communication, as a wired communication method with ultra-high speed, ultra-large capacity, and ultra-long distance transmission, is receiving increasing attention and adoption.

[0003] Existing pressure-holding covers for robots have poor positioning accuracy and relatively poor pressure-holding performance. To address this, we propose a thickened pressure-holding cover. Utility Model Content

[0004] The purpose of this invention is to provide a thickened pressure-holding cap to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a thickened pressure-holding cap, comprising a pressure-holding cap body, wherein an inner groove is formed on one side of the pressure-holding cap body, and multiple annular reinforcing ribs and multiple strip reinforcing ribs are provided on the pressure-holding cap body at the inner groove, wherein the strip reinforcing ribs and annular reinforcing ribs are intersecting; an annular groove is formed on the outer side of the pressure-holding cap body at the inner groove; multiple fixing ears are provided on the outer side of the pressure-holding cap body, wherein the fixing ears have first through holes, and multiple second through holes are formed on the outer side of the annular groove of the pressure-holding cap body.

[0006] Preferably, there are two annular reinforcing ribs and eight strip reinforcing ribs, which are evenly distributed.

[0007] Preferably, each of the annular reinforcing ribs has eight grooves, and the spacing between adjacent grooves is the same.

[0008] Preferably, the bottom of the pressure-holding cover body has a concave step structure at the second through hole, and the pressure-holding cover body has a blind hole at the concave step structure.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the pressure-holding cover body is provided with multiple annular reinforcing ribs and multiple strip reinforcing ribs in the inner groove, and the strip reinforcing ribs and annular reinforcing ribs are intersected to enhance the pressure-holding performance of the pressure-holding cover; the bottom of the pressure-holding cover body is provided with an inner concave step structure at the second through hole, and a blind hole is provided at the inner concave step structure. The inner concave step structure can play a good positioning role, making the device installation more accurate; when applied to fiber optic accessory robots, through rigorous structural design, while ensuring the structural strength of the product, high-precision machining is also required to ensure that the product assembly accuracy reaches ±0.01mm, forming an effective sealing effect.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0018] Please see Figure 1-5 In this embodiment of the utility model, a thickened pressure-holding cover includes a pressure-holding cover body 1. An inner groove 6 is formed on one side of the pressure-holding cover body 1. Multiple annular reinforcing ribs 7 and multiple strip reinforcing ribs 8 are provided on the pressure-holding cover body 1 at the inner groove 6. The strip reinforcing ribs 8 and annular reinforcing ribs 7 are intersecting to enhance the pressure-holding performance of the pressure-holding cover. There are two annular reinforcing ribs 7 and eight strip reinforcing ribs 8, which are evenly distributed. Each annular reinforcing rib 7 has eight slots, with the same spacing between adjacent slots. An annular groove 5 is formed on the outer side of the inner groove 6 of the pressure-holding cover body 1. Applied to fiber optic accessory robots, through rigorous structural design, while ensuring the structural strength of the product, high-precision machining is also required to ensure that the product assembly accuracy reaches ±0.01mm, forming an effective sealing effect.
