Abstract

The utility model relates to an adjustable aerated shoe stretcher, composed of a front bung and a rear bracing plate. The front bung is an air bag, and the air bag and the rear bracing plate are connected by a connecting bracket. The connecting bracket is provided with a gas tube which is through the air bag. The connecting bracket is provided with a staggered regulating mechanism or an integral fixed bracket. Because the front bung is the air bag, the shoe stretcher doesn't need to be aerated when in use, and can be put in the shoes. The rear bracing plate is put in the heel, and then the connecting bracket is adjust. No adjustment is needed if the bracket is the integral fixed bracket, and then the gas is aerated into the front bung to make everywhere of the anterior part of the shoes obtains supporting. The effect is good, and the utility model is not afraid of being pressed and can not distort physically.

Description

The adjustable type inflatable shoe tree

Technical field

The utility model relates to a kind of fillers, belongs to daily living article, can be widely used in leather shoes, boots, sneakers etc.

Background technology

Footwear are the most frequently used requirement, kind is a lot, and most footwear to be afraid of to be squeezed, the time of putting has been grown also and can be out of shape naturally, for example leather shoes, leather boots, leather sneakers etc. will directly sustain damage after vamp is squeezed on the one hand, produce concave deformation on the other hand, the while footwear have been put for a long time footwear nation and also can be out of shape naturally, influence attractive in appearance.Therefore, people are squeezed and distortion naturally in order to prevent footwear, just put chock in footwear, existing footwear chock adopts plastics or sponge to make, and the often unified typing of size, shape is regulated very poor automatically, particularly toe cap etc. is located to be difficult to relate to, so original footwear chock support effect is poor.

Summary of the invention

The purpose of this utility model provides a kind of length and can regulate, and size can be flexible, the adjustable type inflatable shoe tree that support effect is good.

The technical scheme of the utility model adjustable type inflatable shoe tree is: be made up of preceding plug and rear bearing sheet, it is characterized in that described preceding plug is an air bag, there is the support of connection to link to each other between air bag and the rear bearing sheet, connect in the support and be shaped on gas tube, in the gas tube ventilation capsule, connecting support has length governor motion or unitary fixed support.

The utility model adjustable type inflatable shoe tree is because preceding plug is an air bag, begin in use not inflate, can at first put into difform footwear, and rear bearing sheet is put in the heel of a shoe, regulate the connection support again, if the unitary fixed support just need not regulated, then charge into gas in the plug forward, each position, front portion in the footwear is supported, effective, be not afraid of pressurized, can be out of shape naturally.Can chew by the simple gas of mounting structure for the gas tube position, structure and kind that gas is chewed are a lot, can chew as tire gas, and swimming lifesaving circle gas is chewed etc.More convenient for air inlet, better effects if can be shaped on the valve pocket of the check valve of taper in gas is chewed, steel ball is installed in the valve pocket.

The specific embodiment

The utility model discloses a kind of adjustable type inflatable shoe tree, mainly partly make up by preceding plug (with anterior cooperation the in the footwear) and two of rear bearing sheets (cooperating) with heel of a shoe, plug is an inflatable air bag 1 before its main being characterised in that, link to each other by being connected support 3 between air bag and the rear bearing sheet 12, connect in the support and be shaped on gas tube 4, in the gas tube 4 ventilation capsules 1, so air bag 1 has the secure fit place with the junction that is connected support 3, and connect support length (length) governor motion is arranged, make fillers be applicable to different big or small footwear, or the unitary fixed support.And described air bag can be made by various inflatable materials such as rubber or plastics, shape as shown in each view, the front portion of similar shoes or socks, but also can be other shape.Have gas to chew hole 5 ' installation gas in gas tube 4 and

chew

5,17, gas has been chewed and has been covered 6, helps air inlet and pressurize, the gas of structure that gas is chewed such as tire (automobile, bicycle) chews 17, and as Fig. 8, shown in Figure 9, or swimming lifesaving circle gas is chewed, as Fig. 1-shown in Figure 7, technical scheme is a lot.And can in gas is chewed, be shaped on the valve pocket shape of check valve, and steel ball is installed in the valve pocket, the one-way valve structures as commonly used makes the inflation better effects if.The technical scheme that the length of described connection support is regulated (stretching) mechanism also is diversified, can be shown in Fig. 1, Fig. 2 etc., be to connect support 3 to be shaped on adjusting screw(rod) 7, in rear bearing sheet 12, be shaped on sleeve pipe 11, screw rod 7 is inserted in the sleeve pipe 11, the adjusting nut 9 that is shaped on internal thread is installed, the threads engaged of adjusting nut 9 and screw rod 7 at the sleeve pipe head, the outside of adjusting nut 9 has a turning collar 10 to drive, and turning collar drives nut.For air bag and rear bearing sheet are not rotated when rotating adjusting nut, can on screw rod 7, be shaped on guide-localization groove 8, be shaped on guiding tenon 13 at sleeve pipe 11 inwalls, guiding tenon 13 matches with guide-localization groove 8.But also can be shaped on

guide plate

14,15 on connection support 3, cover plate 19 is arranged on the rear bearing sheet 12, cover plate 19 is formed the semicircle buckets with gripper shoe 12, and guide plate 14 inserts in cover plates 19 second drums, as shown in Figure 3, Figure 4.And can between turning collar 10 inwalls and adjusting nut 9 outer walls, be shaped on fit key, make when rotation two keys good reliability of working in coordination.

For easy when adjusting nut and turning collar are installed, described adjusting nut 9 can be made and split two halves slit bamboo or chopped wood shape, shown in Fig. 2 waits, and in the end, be shaped on snap ring 9 ', be shaped on draw-in groove 16 at sleeve pipe 11 oral area outer walls, draw-in groove 16 and snap ring 9 ' match.In order to make air bag and the firm and reliable connection that is connected support, can connect baffle plate 2 with being connected between the support 3 to install at air bag 1, connect support 3 have interface 3 ', air bag have connecting portion 1 ', by the connecting portion 1 of the interface 3 ' insertion air bag 1 that connects support 3 ' in, connecting portion 1 ' have outward dead ring 2 ' fix dead ring 2 ' make one or split with baffle plate 2, as Fig. 2, shown in Figure 4.Its concrete technical scheme of length governor motion that connects support has a lot, and the example of another type is to connect support to be shaped on straight-bar, is shaped on sleeve pipe in rear bearing sheet, is shaped on pinhole on straight-bar and the sleeve pipe respectively, and pin is installed in the pinhole.Be about to adjusting screw(rod) and change straight-bar into, the sleeve pipe of rear bearing sheet is the same substantially, and the pinhole in straight-bar or the sleeve pipe can have many, is fixed by the hole on the diverse location, and the length of fillers is just different.The example of another type is shaped on hole clipping for the length governor motion that connects support is to connect support to be shaped on straight-bar in the straight-bar, be shaped on clamp in rear bearing sheet, and the head of clamp is shaped on trip, and the trip of clamp head matches with hole clipping in the straight-bar.Be that first type adjusting screw(rod) is changed into straight-bar equally, and the sleeve pipe in the rear bearing sheet is changed into clamp (card), and the trip of clamp head and the hole clipping of straight-bar fix, and hole clipping has many, trip inserts the hole clipping of diverse location, and the length of fillers is just different.And unitary fixed support technology scheme is more, but shown in the illustration 10, support 18 connects rear bearing sheets, and preceding have an air bag 1, air bag connecting portion 1 ' with carriage interface 3 ' match, support has gas to chew 5.
