Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing covers, and particularly relates to a split spiral cap structure. Background Art
[0002] Sealing covers are often used to seal bottled liquids or gases, and the sealing effect of the sealing cover also determines the length of the storage time of the items. The plastic bucket lids in the prior art have the problem of leakage, that is, poor sealing performance, and are inevitably damaged during transportation. Content of the Utility Model
[0003] Aiming at the deficiencies of the prior art, the main purpose of the utility model is to provide a split spiral cap structure with good sealing performance and convenient disassembly and assembly.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A split spiral cap structure includes an outer ring cap and an inner ring cap threadedly connected to the outer ring cap. The outer ring cap includes a fixing layer located outside the plastic bucket and a connecting layer located inside the plastic bucket. A clamping groove that can be sleeved on the plastic bucket is formed between the fixing layer and the connecting layer. A fixing ring with an inverted hook-shaped cross-section is arranged on the clamping groove. An internal thread section is arranged on the connecting layer. The outer ring cap includes a cap body and an external thread section that cooperates with the internal thread section.
[0005] Preferably, a rubber sealing ring is arranged at the top of the clamping groove.
[0006] Preferably, an extended positioning ring is arranged at the top of the cap body, and a positioning groove corresponding to the extended positioning ring is arranged at the top of the outer ring cap.
[0007] Preferably, a plurality of lower grooves are arranged on the inner ring cap.
[0008] The utility model has the following advantages compared with the prior art: It solves the problem of poor sealing of plastic buckets. The split spiral cap tightly buckles the outer ring cap on the plastic bucket, then places the inner ring cap inside the outer ring cap, and then rotates and tightens it, so as to achieve the function of sealing the plastic bucket. The inner ring cap and the outer ring cap of the split spiral cap should fit closely. It solves the situation of liquid overflow during long-distance transportation. Preferably, a rubber sealing ring is arranged at the top of the clamping groove. The rubber sealing ring can play an auxiliary sealing role. Description of the Drawings
[0009] Figure 1 It is a schematic structural diagram of the inner ring cap of a split spiral cap structure of the utility model;
[0010] Figure 2 It is a schematic structural diagram of the outer ring cap of a split spiral cap structure of the utility model;
[0011] Figure 3 This is a schematic structural view of the inner ring cover and the outer ring cover of a split spiral cap structure of the present utility model when they are fitted together.
[0012] In the figure: 1. Outer ring cover; 11. Fixed layer; 12. Connecting layer; 121. Inner thread section; 13. Clamping groove; 131. Fixed ring; 132. Rubber sealing ring; 14. Positioning groove; 2. Inner ring cover; 21. Cover body; 211. Extended positioning ring; 22. Outer thread section; 23. Lower groove. Specific embodiments
[0013] The present utility model will be further described below with reference to the accompanying drawings.
[0014] As Figure 1 shown, a split spiral cap structure includes an outer ring cover 1 and an inner ring cover 2 threadedly connected to the outer ring cover 1. The outer ring cover 1 includes a fixed layer 11 located outside the plastic bucket and a connecting layer 12 located inside the plastic bucket. A clamping groove 13 that can be sleeved on the plastic bucket is formed between the fixed layer 11 and the connecting layer 12. A fixed ring 131 with an inverted hook-shaped cross section is provided on the clamping groove 13. An inner thread section 121 is provided on the connecting layer 12. The inner ring cover 2 includes a cover body 21 and an outer thread section 22 that cooperates with the inner thread section 121.
[0015] The split spiral cap structure of this solution solves the problem of poor sealing of plastic buckets. For the split spiral cap, the outer ring cover 1 is tightly fastened on the plastic bucket, and then the inner ring cover 2 is placed inside the outer ring cover 1 and rotated and tightened, so as to achieve the function of sealing the plastic bucket. The inner ring cover 2 and the outer ring cover 1 of the split spiral cap should fit closely. It solves the problem of liquid overflow during long-distance transportation. Preferably, a rubber sealing ring 132 is provided at the top of the clamping groove 13. The rubber sealing ring 132 can play an auxiliary sealing role.
[0016] Preferably, an extended positioning ring 211 is provided at the top of the cover body 21, and a positioning groove 14 corresponding to the extended positioning ring 211 is provided at the top of the outer ring cover 1.
[0017] The purpose of such a design is to facilitate the assembly of the inner ring cover 2 and the outer ring cover 1 in place, with more precise cooperation and ensure sealing performance.
[0018] Preferably, a plurality of lower grooves 23 are provided on the inner ring cover 2. The inner ring cover 2 has a concave design of the lower grooves 23, so that it can be better fastened on the toilet bowl and is more convenient to take. The inner ring has a concave design and grid design, making the liquid more stable during transportation.
[0019] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
