Description

Technical Field

[0001] The present invention relates to the technical field of diving devices, and more particularly to a pressure-resistant diving suit. Background Art

[0002] A diving suit is diving equipment used to prevent the body temperature from dropping too fast during diving, resulting in hypothermia. At the same time, it can also protect divers from the harm of reefs or harmful animals and plants. When wearing a dry diving suit, the body is completely isolated from water. Depending on the water temperature, a sweater can be worn inside to enhance heat preservation. It must be used after training and is used for diving in cold areas. In cold waters, dry diving suits are more commonly used. Of course, they are also more expensive than wet diving suits. The styles are mostly one-piece, and there are at least three materials for dry diving suits: foam synthetic rubber, synthetic rubber, and nylon materials.

[0003] For the pressure-resistant diving suit used in shallow waters, it is generally close to the user's body and relatively tight. When in use, in order to facilitate its wearing and taking off, the diving suit used in shallow waters generally does not have a headgear. When diving in shallow waters, it needs to be used in conjunction with an oxygen supply device, that is, wearing a breathing mask. The breathing mask is head-mounted, that is, it is worn on the head through an elastic band until the breathing mask is worn properly. During this process, when in use, the elastic band for wearing the breathing mask may become loose or shift in position when the user is diving. This has an impact on the wearing of the breathing mask, that is, the rubber mask that fits and seals with the face may have a gap with the face, causing water to infiltrate, which has a certain impact on its use safety. The existing diving suits used in shallow waters lack an auxiliary structure that matches with the breathing mask for use to improve its use safety.

[0035] This solution provides a connection function for both the headgear 2 and the diving suit main body 1 through the provided connection components. On the basis of ensuring the connection sealing stability between the headgear 2 and the diving suit main body 1, it is convenient to disassemble and assemble, that is, convenient to wear. When it is necessary to take off the headgear 2, first release the clamping connection between the connection plug 404 and the fastening buckle 503, that is, pull out the connection plug 404, and then release the clamping connection between the sealing snap ring 502 and the sealing slot 402. The operation is convenient.

[0036] When performing the wearing work of the breathing mask 3, generally, the elastic headband 31 connected to the breathing mask 3 is put on the user's head. In order to prevent the elastic headband 31 from sliding during use and affecting the use of the breathing mask 3, this solution uses a stabilizing component provided on the back side of the headgear 2 in cooperation with the elastic headband 31 to improve the wearing stability of the elastic headband 31 and prevent the breathing mask 3 from shifting or loosening during use, thereby improving the use stability and safety of the breathing mask 3. That is, the connection patch plate 601 in the stabilizing component is fixedly arranged at the back side position of the headgear 2, and a hanging buckle groove body 602 is arranged in the middle position of the outer wall surface of the connection patch plate 601. An accommodating through groove 603 is arranged in the connection patch plate 601, and the accommodating through groove 603 is symmetrically arranged with respect to the hanging buckle groove body 602. The accommodating through groove 603 and the hanging buckle groove body 602 are communicated. The connection sealing plate 604 and one end of the connection patch plate 601 are fixedly connected by screws. The length of the carrier 606 is set to be equal to the notch length of the accommodating through groove 603; on one side of the connection sealing plate 604, connection springs 605 are symmetrically fixedly arranged, and the other ends of the connection springs 605 are fixedly arranged on one side of the carrier 606. The carrier 606 is connected to the loading structure.

[0037] Among them, the placement cavity 701 in the loading structure is arranged on one side of the carrier 606, the mounting plate member 702 is arranged at the cavity opening position of the placement cavity 701, and the mounting plate member 702 and the carrier 606 are fixed by screws. Through slots 703 are equidistantly arranged in the mounting plate member 702. The support bar 704 is inserted through the through slots 703. One end of the support bar 704 is fixedly arranged on one side of the auxiliary plate bar 705, and the other end of the support bar 704 is fixedly welded on the side wall of the support bar body 707. The auxiliary plate bar 705 is placed in the placement cavity 701, and auxiliary springs 706 are symmetrically arranged on the upper and lower sides of the auxiliary plate bar 705. The width of the slot opening of the through slot 703 is equal to the thickness of the support bar 704, and the length of the slot opening of the through slot 703 is greater than the thickness of the support bar 704. The number of sets of the through slot 703 and the support bar 704 is the same, that is, one support bar 704 is inserted through one through slot 703. The auxiliary plate bar 705 is movably arranged in the placement cavity 701 and is provided with one set. An auxiliary structure is arranged on one side of the support bar body 707. The auxiliary structure includes a limit extension stud 801 and an anti-slip barb 802. The limit extension studs 801 are equidistantly fixed on one side of the support bar body 707, and anti-slip barbs 802 are equidistantly fixed on the side of the limit extension stud 801. The anti-slip barbs 802 are symmetrically arranged on both sides of the column surface of the limit extension stud 801 and are inclined downward. A stable auxiliary fitting is also arranged on the connection patch plate 601, which includes a threaded hole groove 901, a fastening screw 902, and a cylindrical handle 903. The threaded hole groove 901 is arranged in the connection patch plate 601, and the threaded hole groove 901 is communicated with the accommodation through slot 603. The threaded hole groove 901 is threadedly connected with the fastening screw 902 in a matching manner. One end of the fastening screw 902 is fixedly provided with a cylindrical handle 903.

[0038] For the installation and use of the stabilizing assembly, firstly, the support strip 704 on one side of the auxiliary strip 705 is correspondingly inserted into and penetrated through the through groove 703 in the mounting plate 702. After the support strip 704 passes through the through groove 703, one end of the support strip 704 is attached to one side of the support strip body 707, and then they are welded and fixed one by one. At the same time, the auxiliary strip 705 set at the other end of the support strip 704 is placed in the placement cavity 701 in the carrier 606, and then the mounting plate 702 and The cavity opening of the cavity 701 is sealed, that is, the mounting plate 702 is in contact with the carrier 606, and then connected and fixed by screws; then the carrier 606 and the supporting strip 707 are placed in the receiving groove 603 of the connecting plate 601, until the set connecting sealing plate 604 is in contact with the outer end of the connecting plate 601, that is, the connecting sealing plate 604 seals one end of the receiving groove 603, and then connects and fixes by screws. After installation, the supporting strip 707 is set at the other end. The limit extension column head 801 on one side will be in the buckle groove body 602 of the connecting plate 601 at the beginning. Since the carrier 606 is connected to the connecting sealing plate 604 through the connecting spring 605, the carrier 606 can move in the receiving groove 603, and the limit extension column head 801 can also be retracted into the receiving groove 603 by pressing the finger when the elastic headband 31 is engaged with the buckle groove body 602. At this time, when the limit extension column head 801 is pressed into the receiving groove 603 The connecting spring 605 arranged between the carrier 606 and the mounting plate 702 will also be squeezed. When the elastic headband 31 is stuck in the hook groove 602, the limiting extension column head 801 will be loosened, that is, the squeezing of the limiting extension column head 801 will be released. At the same time, the limiting extension column head 801 will also enter the hook groove 602 under the rebound action of the connecting spring 605, thereby providing a limiting effect on the elastic headband 31, making it difficult for the elastic headband 31 to separate from the hook groove 602.

[0039] When a component in the stabilizing assembly is damaged, it can also be quickly disassembled for inspection and maintenance, that is, the connecting sealing plate 604 is directly removed to release the connection and fixing work between the connecting sealing plate 604 and the connecting plate 601, and then the connecting plate 601 can be disassembled. When the connecting plate 601 is removed, the carrier 606 and the supporting strip 707 are taken out at the same time, and then the connection and fixing of the mounting plate 702 and the carrier 606 are released, and the screw fixing connection between the two is released, which is easy to operate and convenient for use and subsequent maintenance work; after the inspection, the installation can be quickly completed according to the same installation operation as mentioned above.

[0040] After the carrier 606 and the support strip 707 are installed, the initial state of the support strip 707 is set corresponding to the position of the threaded hole groove 901. That is, in this solution, a fastening screw 902 is threadedly connected in the threaded hole groove 901, and the fastening screw 902 is driven by a cylindrical handle 903 provided at its end. At this time, the fastening screw 902 can provide an extrusion effect on the support strip 707. The purpose is to drive the limit extension stud 801 to move by extruding the support strip 707, so that the limit extension stud 801 has better stability for the elastic headband 31 stuck in the hanging buckle groove body 602.

[0041] When putting the elastic headband 31 on the user's head, the elastic headband 31 needs to be passed through the hanging buckle groove body 602 at the middle position on the outside of the connecting patch panel 601. Before this process, since the installed limit extension stud 801 will be in the hanging buckle groove body 602, it is necessary to press the limit extension stud 801 with a finger to make the limit extension stud 801 retract into the receiving through groove 603. While pressing the limit extension stud 801, the elastic headband 31 is stuck in the hanging buckle groove body 602. After the elastic headband 31 is stuck in the hanging buckle groove body 602, the extrusion on the limit extension stud 801 is released. That is, the limit extension stud 801 rebounds under the action of the connecting spring 605 and will still be in the hanging buckle groove body 602, and the support strip 707 connected to the limit extension stud 801 reaches the position directly below the threaded hole groove 901. At this time, the elastic headband 31 is in close contact with the bottom end of the hanging buckle groove body 602, and the limit extension stud 801 provides a limiting effect on the elastic headband 31. Then, the wearing position of the breathing mask 3 can be adjusted.

[0042] In order to further improve the wearing stability of the elastic headband 31, after the elastic headband 31 is clamped in the hanging buckle groove body 602, at the same time, the fastening screw 902 is rotated by the cylindrical handle 903, so that one end of the fastening screw 902 squeezes the support strip body 707. Among them, the support strip 704 connected to one side of the support strip body 707 can move up and down in the through groove body 703. That is, when the fastening screw 902 squeezes the support strip body 707, the support strip body 707 will move downward, and the support strip body 707 drives the limit extension stud 801 on its other side to move downward. The purpose is to further improve the limit stability of the elastic headband 31. And this solution also has anti-slip barbs 802 on the cylindrical side wall of the limit extension stud 801. That is, after the support strip body 707 is pressed down by the fastening screw 902, the limit extension stud 801 drives the anti-slip barbs 802 to move until the anti-slip barbs 802 contact and squeeze the elastic headband 31. Finally, the fastening screw 902 is tightened by the cylindrical handle 903. The anti-slip barbs 802 provided squeeze and clamp the elastic headband 31, providing a locking effect on the elastic headband 31, which can well prevent the elastic headband 31 from shifting in position during use, and further avoid the problems of position shift or loose wearing of the breathing mask 3 during use.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
