Detailed Description
The following specific examples are given by way of illustration only and not by way of limitation, and it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made in the examples without inventive faculty, and yet still be protected by the scope of the claims.
The scheme is realized by the following technical means:
example 1: as a common product in life, the inflatable equipment appliance is widely applied to the fields of inflatable trampoline castle toys for children to play actively, inflatable archways for arranging scene activities, temporary tents for fighting flood and relieving disaster, aspects and the like. In these products, a gas chamber is enclosed by an outer covering, which is usually made of double-sided mesh PVC cloth, and thus has good sealing properties, thereby isolating the gas chamber from the external space. For the purpose of inflating the air chamber, an inflation connection socket 2 for connecting with an inflation tube 1 is usually installed by sewing or bonding on the surface of the covering material layer.
In this embodiment, a connecting device for an inflation tube seat is provided, which has a simple structure, is convenient to assemble and disassemble, and is efficient and stable in connection. Similar to the conventional structure, the inflation tube socket connecting device also comprises an inflation tube 1 for inflating the air chamber of the product to be inflated and an inflation connecting socket 2 for matching and installing the inflation tube 1. The inflation tube 1 is made of nylon or PVC and other materials with certain elastic deformation capacity, is in a hollow cylinder shape, one end of the inflation tube 1 protrudes outwards to form a cylindrical tubular connecting part 1a which is used for being connected and fixed with the inflation connecting seat 2, and the other end of the inflation tube is fixedly connected with an air outlet pipe which is directly led out outwards by an air pump device or a compressed air tank. The center of the air inflation connecting seat 2 is provided with a receiving part 2a which is corresponding to the connecting part 1a and penetrates through the inner wall surface and the outer wall surface of the air chamber and is also in a cylindrical hole shape, the radial dimension of the receiving part 2a is slightly larger than that of the connecting part 1a, so that the connecting part 1a can still reciprocate along the common central axis direction after being inserted into the receiving part 2 a. The most important structure of the connecting device of the inflation tube seat is a connecting component 3 which is arranged between the connecting part 1a and the accommodating part 2a and can quickly complete locking, fixing, disassembling and separating of two parts.
The connecting assembly 3 comprises a locking connecting piece 4 which can prevent the two parts from moving reversely to separate from each other and keep a stable connecting state after the connecting part 1a is inserted into the accommodating part 2a from the outside to the inside, and an unlocking trigger piece 5 which can release the connecting and fixing effect of the locking connecting piece 4 when the two parts are required to be disassembled and separated. The locking connecting piece 4 is formed by processing iron-carbon alloy serving as a main material, and has good resilience resetting performance and certain rigidity strength. The locking connecting piece 4 is a hollow ring shape as a whole, the outer side surface of the locking connecting piece is fixedly connected with the inner wall surface of the accommodating part 2a, and meanwhile, the inner side surface of the locking connecting piece 4 is inwards protruded and extended to form a plurality of movable clamping connection parts 4a which are uniformly distributed along the annular inner side surface and are used for abutting against the outer wall surface of the connecting part 1 a. Specifically, a step surface is formed in an inner cavity of the accommodating part 2a, the locking connecting piece 4 is placed in the accommodating cavity in a horizontal state, the lower surface of the locking connecting piece is tightly attached to the upper surface of the step surface, and then a compression ring which is in interference fit with the inner wall of the accommodating cavity is pressed into the upper part of the locking connecting piece 4 along the radial direction of the accommodating cavity and abuts against the upper surface of the locking connecting piece 4, so that the locking connecting piece 4 is completely fixed. It should be noted that the locking connector 4 is disposed along a direction parallel to the radial section of the plug-in receiving portion 2a, and the outer portion of the locking connector is fixedly connected with the plug-in receiving portion 2a by engaging or locking so that the locking connector 4 can no longer move relative to the plug-in receiving portion 2 a. When the locking connector 4 is manufactured, the movable connecting portion 1a is bent toward one end of the plug receiving portion 2a along the direction in which the plug connecting portion 1a is inserted, and the thickness of the movable engaging portion 4a itself at each position is gradually reduced from the position where the movable engaging portion is connected to the annular body of the locking connector 4 toward the end portion thereof, and the radial dimension of the hollow region surrounded by all the movable engaging portions 4a must be smaller than the radial dimension of the plug connecting portion 1 a.
When the connecting part 1a is gradually inserted into the cavity of the accommodating part 2a from outside to inside, the end part of the accommodating part 2a firstly abuts against and props against the upper side surface of the movable clamping part 4a from outside to inside, so that the movable clamping part is bent downwards and the hollow area formed by the surrounding of each movable clamping part 4a is expanded; when the plug-in connector 1a continues to move inward and is inserted, the inner portion of the movable engaging portion 4a keeps abutting against the outer wall surface of the plug-in connector 1a and slides along the outer wall surface until the end of the plug-in connector 1a abuts against and cannot move inward. At this time, if the connecting portion 1a is pulled out with respect to the receiving portion 2a, the movable engaging portion 4a annularly distributed around the outer side of the connecting portion 1a on the locking connecting member 4 is more closely attached to or even embedded into the connecting portion 1a near the inner end, thereby achieving the locking and fixing effect on the inflation tube 1 and the inflation connecting seat 2.
In the connection assembly 3, an unlocking trigger 5 is further included for releasing the fixed state between the connection portion 1a and the receiving portion 2a when the inflation tube 1 and the inflation connection seat 2 need to be disassembled to separate the two portions. This unblock trigger 5 wholly is a hollow tubulose, can cup joint install in between connecting portion 1a and the portion of acceping 2a and along the axial of gas tube 1 carries out reciprocating motion, unblock trigger 5 includes can insert connecting portion 1a outer wall with the butt portion 5a in the space between the portion of acceping 2a inner wall, when connecting portion 1a and portion of acceping 2a are in locking connecting piece 4 uses down fixed connection together, unblock trigger 5 can move to locking connecting piece 4 one end and through self lower edge to the upper surface of activity joint portion 4a supports and leans on, makes further buckling deformation of activity joint portion 4a and with the outer wall phase separation of connecting portion 1a releases locking fixed state. Specifically, unblock trigger 5 still includes and is located its spacing portion 5b that extends along the horizontal direction by outside tip, spacing portion 5 b's radial dimension is greater than the radial dimension of portion 2a is being pressed spacing portion 5b makes unblock trigger 5 wholly when inwards moving, through spacing portion 5 b's lower surface with the laminating of portion 2 a's upper surface is supported and is leaned on the effect, realizes getting into the restriction of the inside degree of depth of portion 2a to connecting portion 1a, avoids it excessively to get into can't outwards pop out.
When the inflation tube seat connecting device is actually used, sometimes the inflation tube 1 and the inflation connecting seat 2 do not need to be disassembled, but the inserting depth of the two parts needs to be adjusted, namely, the connection locking effect needs to be immediately recovered after the connection locking state between the connecting part 1a and the accommodating part 2a is temporarily released. According to the use requirement, when the locking connecting piece 4 and the unlocking trigger 5 are used in cooperation, the two components are designed in structural dimensions such that when the unlocking trigger 5 is pressed downwards to the lowest position, the lower surface of the limiting portion 5b abuts against and is attached to the upper surface of the accommodating portion 2a, the movable clamping portion 4a is bent and deformed through pressing, and at the moment, the lower edge of the limiting portion 5b does not exceed the movable clamping portion 4 a. The upper surface of movable joint portion 4a just can laminate with the lower terminal surface of unblock trigger 5 all the time this moment, realizes when removing the extrusion to unblock trigger 5, and it can be reset by jack-up upwards under the elastic action of movable joint portion 4a, avoids appearing unblock trigger 5 and takes place the unable condition that kick-backs and reset of auto-lock.
Preferably, in order to further improve the effect of fixing the connection, a plurality of annular clamping grooves which are annularly recessed and are axially arranged along the connection portion 1a at intervals may be formed on the outer circumferential surface of the connection portion 1a, and are used for matching with the movable clamping portion 4a to obtain a larger abutting acting force. Furthermore, connecting portion 1a can be made of nylon materials with certain elasticity, and not only can the friction force when the medial extremity of activity joint portion 4a is closely attached to its surface or is embedded be increased, but also can be recovered by oneself in the state of not atress when the outer wall face of the part is depressed and damaged due to leaning against the atress, effectively leaning against the fixed ability to activity joint portion 4a again.
Example 2: in the solution described in the above embodiment 1, it is considered that when the inflation tube seat connecting device is actually used, although the inflation tube 1 achieves stable locking connection with the inflation connecting seat 2, as the process of gradually inflating into the air chamber progresses, the air pressure in the air chamber cavity gradually increases until the external atmospheric pressure is exceeded. At this moment, the gap space between the inflation tube 1 and the inflation connecting seat 2 can lead to gas leakage outwards, so that the inflation efficiency is reduced, the resource is wasted, and particularly when the inflation tube seat connecting device is applied to gas storage devices of flammable and combustible types such as oxygen and gas, the leakage happens, and serious potential safety hazards are brought to peripheral personnel.
Therefore, in the present embodiment, a self-sealing structure 6 capable of preventing the gas in the gas chamber from leaking out from the gap between the connection portion 1a and the receiving portion 2a is further provided inside the gas charging connector holder 2. Specifically, the self-sealing structure 6 of the self-sealing structure 6 mainly includes an annular elastic sealing ring 6a installed inside the accommodating part 2a, the elastic sealing ring 6a is installed between the locking connector 4 and the step surface, the outer peripheral surface of the elastic sealing ring is closely attached and fixed to the inner wall of the accommodating part 2a, and the inner peripheral surface of the elastic sealing ring 6a extends from outside to inside to form a conical sealing part 6a1 protruding toward the air chamber side. When the inflation tube 1 is inserted, the inner wall surface of the conical sealing part 6a1 is attached to the outer side tube wall at the lower part, and when the leaked partial gas enters the annular space at the side, close to the air chamber, of the conical sealing part 6a1 from inside to outside, the conical sealing part 6a1 can be attached to the surface of the inflation tube 1 more closely, the sealing effect can be better along with the increase of the air pressure, and the effective blocking sealing effect is achieved.
While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
