Description

Collude wrist unscrambler

Technical Field

The utility model relates to the technical field of teaching aids, in particular to a wrist hooking corrector.

Background

The writing wrist hooking means that when a pupil writes, the palm bends towards the inner side of the wrist in a wrong posture and habit, the wrist hooking can cause that children write and ugly write slowly, some devices for preventing the wrist hooking exist in the market, but most devices are arranged on the arm and the palm, the length is insufficient, when the device is used, the wrist hooking and the writing of the thumb towards the direction of 9 points inwards cannot be completely prevented, and the effectiveness is incomplete.

Disclosure of Invention

In order to solve the problems in the prior art, the utility model designs the wrist hooking corrector which can effectively correct the wrist hooking problem when a student writes.

The technical scheme adopted by the utility model is as follows: the wrist hooking corrector comprises a keel plate, the front end of the keel plate protrudes forwards to form a narrow plate section, and the keel plate and the protruding narrow plate section are respectively provided with a fixing belt. The keel plate is fixed on the arm through the fixing band, the front convex narrow plate section is fixed on the second joint of the thumb through the fixing band, the thumb and the arm are kept in a straight line during writing, the writing wrist hooking is prevented, and the wrist hooking correction effect is achieved.

Furthermore, be provided with two fixed bands on the keel plate, constitute by the magic subsides respectively, the both ends that are close to the plate body on the keel plate are provided with the perforation respectively, and two magic subsides pass from two perforations respectively.

Furthermore, the narrow plate section is also provided with a through hole, the fixing band of the narrow plate section is composed of an elastic band, and the elastic band penetrates through the through hole of the narrow plate section.

Furthermore, the keel plate is a long straight plate, the upper side edge of the front convex narrow plate section is flush with the upper side edge of the keel plate, and the joint of the front side end of the keel plate and the lower side edge of the narrow plate section is an arc-shaped edge jointed with a connecting arc line of a thumb and a wrist.

Furthermore, the keel plate and the inner side surface of the front convex narrow plate section are integrally provided with a layer of soft gasket.

Further, the length of the keel plate is 12cm, the width of the keel plate is 4cm, and the length of the narrow plate section is 3cm, and the width of the narrow plate section is 2 cm.

Compared with the prior art, the wrist hooking corrector designed by the patent of the utility model has the advantages that: the front end of the keel plate is provided with the front convex narrow plate section to fix the thumb of the writing hand, and the keel plate is bound on the arm through the fixing belt, so that the thumb and the arm can be ensured to be in a straight line during writing, and the wrist is not hooked inwards, thereby not only effectively preventing the writing from hooking the wrist, but also preventing the thumb and the forefinger from facing to the 9 o' clock direction during writing; the keel plate and the narrow plate section are respectively bound through magic tapes or elastic bands, so that the adjustment is convenient, and the use requirements of different students are met; the soft pad on the inner side protects the skin and prevents the arm from being damaged by long-term use.

Drawings

Fig. 1 is a schematic structural diagram of the wrist hooking corrector.

Fig. 2 is another structural schematic diagram of the wrist hooking corrector.

In the figure, 1 keel plate, 2 narrow plate sections, 3 magic tapes, 4 elastic bands, 5 liners, 6 perforations and 7 arc-shaped edges.

Detailed Description

The utility model is further described with reference to the following figures and specific embodiments. The technical solutions in the embodiments of the present invention are clearly and completely described, and the described embodiments are only some embodiments, but not all embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative effort belong to the protection scope of the present invention.

Example 1

Referring to fig. 1, the present invention discloses a first embodiment of an ankle-hooking orthosis, which comprises a keel plate 1, wherein a narrow plate section 2 protrudes forward from the anterior end of the keel plate 1. The keel plate 1 is a long straight plate, the upper side edge of the keel plate is flush with the upper side edge of the front convex narrow plate section 2, and the joint of the front side end of the keel plate and the lower side surface of the narrow plate section 2 is a smoothly-bent arc-shaped edge 7 which is attached to the connecting arc line of the thumb and the wrist. The length of the keel plate 1 is 12cm, the width of the keel plate except for the arc edge 7 is 4cm, and the front end of the keel plate is a forward convex narrow plate section 2 which is 3cm long and 2cm wide.

The position that keel board 1 is close to the plate body preceding, the rear end bonds respectively and has the fixed band that the wide magic of round was pasted 3 and is constituted the arm, also bonds on the protruding narrow plate section 2 in front of it and has the fixed band that the narrow magic of round pasted 3 and is constituted the thumb.

In addition, a layer of pad 5 made of sponge or other soft materials is adhered to the inner side of the whole keel plate 1 and the front convex narrow plate section 2, which is contacted with the arm, and the pad 5 is in a concave-convex shape fitting the appearance of the hand and the wrist.

Example 2

As shown in fig. 2, the present invention discloses a second embodiment of a wrist-hooking orthosis, which is different from embodiment 1 in that the medial surface of the keel plate 1 is directly formed into a concave-convex shape fitting the contour arcs of the hand and wrist by a mold during the manufacturing process, and the entire lateral surface of the keel plate 1 is wrapped by a cloth with a soft lining.

The keel plate 1 is opened in the position that is close to the both ends of plate body has twice square perforation 6, has worn the magic respectively in twice square perforation 6 and has pasted 3, and the lower side of plate body is crossed to the magic 3 packages, constitutes keel plate 1's fixed band.

The front convex narrow plate section 2 is also provided with a through hole, an elastic annular loose tightening belt 4 is arranged at the through hole, and the elastic belt 4 is wrapped on the narrow plate section 2 to form a fixing belt.

When the wrist hooking corrector disclosed by the utility model is used, the keel plate 1 is arranged from the thumb to the middle section of the forearm, the front convex narrow plate section 2 is attached to the thumb, the keel plate 1 is tightly bound with the forearm through the magic tape 3, the thumb passes through the elastic band 4 of the narrow plate section 2 to be fixed, and then writing is carried out, at the moment, the wrist hooking corrector can ensure that the thumb and the forearm of a hand writing are always positioned on a straight line, so that the wrist hooking is avoided.

The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the scope of the utility model, which is defined by the appended claims and the description of the utility model.
