Detailed Description

For the purpose of making apparent the objects, technical solutions and advantages of the present utility model, the present utility model will be further described in detail with reference to the following examples and the accompanying drawings, wherein the exemplary embodiments of the present utility model and the descriptions thereof are for illustrating the present utility model only and are not to be construed as limiting the present utility model.

As shown in fig. 1-5, the embodiment of the utility model provides an inflatable matching head special for a french air tap, which comprises an integrally formed cylinder 1 and a joint 2, wherein the cylinder 1 is provided with an air passage 3 in a penetrating manner, the joint 2 is positioned at one end of the air passage 3, and the joint 2 is provided with a through hole 4 communicated with the air passage 3; the other end of the air passage 3 is provided with a horn-shaped flaring 5, and the air passage 3 of the cylinder 1 positioned at one end of the joint 2 is further outwards expanded to form a containing cavity 6 with a large space.

In the implementation, barrel 1 is mainly used to pair french air cock, connect 2 mainly used with the pump pair and be connected, when wearing to the french air cock, compress tightly the tubaeform flaring 5 of barrel 1 in the air cock mouth of french air cock and form sealedly, the air cock valve of french air cock is got into and is fixed a position in holding chamber 6 through tubaeform flaring 5, air flue 3 at this moment, when aerifing, after gas passes through holding chamber 6, air flue 3, tubaeform flaring 5 and gets into the french air cock through holding chamber 4 jack-up air cock, accomplish to aerify, after the completion of aerifing, the air cock valve then compresses tightly in the drill way position of through-hole 4, avoid gas leakage, when needs to pull out, only need take barrel 1 off, and ensure that the air cock valve withdraws from barrel 1 can. Based on this, this embodiment sets up through simple small and exquisite structure, can realize inflating the quick pair installation of pair head and french air cock, convenient to use.

In a specific implementation, the joint 2 is externally provided with external threads. The joint 2 can be quickly and detachably connected with the inflation port of the inflator pump through external threads, so that the joint 2 is convenient to detach and is convenient to carry independently.

In the concrete implementation, the outer part of the joint 2 and the joint of the cylinder body 1 is also concavely provided with an annular groove 7, and a sealing ring is arranged in the annular groove 7. After the connector 2 is connected with the corresponding inflation port of the inflator pump, the sealing ring in the annular groove 7 is extruded to seal the inflation port, so that the inflation is prevented from being influenced by air leakage at the corresponding position.

During implementation, one end of the connector 2 is provided with a clamping ring 8, one end of the cylinder body 1 is inwards sunken to form a clamping groove 9, and the connector 2 is connected with the clamping groove 9 in a matched mode through the clamping ring 8 and is bent and hot-pressed to form an integrated structure through the cylinder body 1 outside the clamping groove 9. The cylinder 1 is higher in its internal air pressure when aerifing, in the prior art in the past, when joint 2 and cylinder 1 adopt split connection, joint 2 and cylinder 1 are connected and leak gas easily, and the two are easy to separate and damage under the atmospheric pressure effect, therefore, this embodiment is based on above problem, adopt integral type structure setting with joint 2 and cylinder 1, utilize snap ring 8 and draw-in groove 9 to pair to connect two zonulae occludens, rethread cylinder 1 buckles and will holistic joint 2 fixedly, rethread hot pressing mode further fuses with two snap ring 8 and draw-in groove 9 junction, thereby can ensure the connection steadiness of both, and adopt the mating mode of snap ring 8 and draw-in groove 9, also make both can respectively earlier processing again integrated into one piece, with the reduction of manufacturing degree of difficulty and cost.

In specific implementation, the outer side of the cylinder body 1 is provided with knurling lines for skid resistance. The knurling of reticulate pattern can increase the roughness of the outside of the cylinder body 1, and then can play a very good anti-skid effect when in use.

In a specific implementation, the end surface of the cylinder 1, which is positioned at one end of the trumpet-shaped flaring 5, is also provided with a marking groove 10. Corresponding identification numbers, symbols and the like are arranged in the marking slot 10 and are used for displaying corresponding information such as product types, names and the like.

In a specific implementation, the inflatable matching head further comprises a deformation cushion (not shown in the figure), wherein the deformation cushion is installed in the air passage 3 between the trumpet-shaped flaring 5, the accommodating cavity 6 and the trumpet-shaped flaring 5, and the middle part of the deformation cushion is penetrated and provided with a through hole.

When in use, because the end part of the cylinder body 1 is tightly pressed at the end part of the French air tap, the cylinder body 1 still is easy to leak air when inflated because the cylinder body 1 needs to be manually pressed or is tightly pressed through a corresponding structure of an inflator pump, therefore, the embodiment can make the air tap valve squeeze and deform to enter or exit the air tap by arranging the deformation cushion and utilizing the deformation characteristic of the deformation cushion, the deformation cushion and the end part of the French air tap squeeze and deform to form a sealing surface which is more attached when in compression, the integral tightness when in inflation is ensured, and the cylinder body 1 can be clamped on the French air tap by utilizing the deformation of the deformation cushion even without additionally pressing the extrusion force of the deformation cushion when in inflation, so that the use is simpler and more convenient.

In a specific implementation, a limiting ring (not shown in the figure) is further arranged at the port of the flared mouth 5 to limit the deformation cushion in the installation area. When the unloading is needed after the inflation is finished, the air tap valve is pressed into the deformation cushion, and then when the air tap valve is pulled out, the deformation cushion is pulled out together easily, and then the deformation cushion is damaged, so that the installation stability of the air tap valve is ensured by arranging the corresponding limiting ring structure and limiting the deformation cushion in the installation area by using the limiting ring.

The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the utility model, and is not meant to limit the scope of the utility model, but to limit the utility model to the particular embodiments, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the utility model are intended to be included within the scope of the utility model.
