Description

Technical Field

[0001] The utility model relates to an opener, more specifically to an opener for animals. Background Art

[0002] Keep the animal's mouth open to facilitate the delivery of food, medicine, or inspection or treatment of its oral cavity. The opener in the prior art is an upper and lower circumferential closed structure. The lower circumferential structure is used to cover the lower jaw of the animal, so that the upper circumferential closed structure can be located in the animal's mouth to keep the animal's mouth open. This opener is easy to use, but it needs to be carried on the person and put on the animal's mouth when it is needed. The solution of the prior art is to use a headband to cover the animal's neck, but it is generally used in conjunction with an anti-bite product. The anti-bite structure has hoops on the animal's mouth. This headgear keeps the animal's mouth closed, and the animal's mouth cannot be in a freely open state when used. The tongue cannot be used to dissipate heat in hot weather. Utility Model Content

[0003] The utility model provides an animal mouth opener, which can be worn on the head and does not affect the free opening of the animal's mouth when not in use.

[0004] The above purpose is achieved through the following technical solutions:

[0005] A veterinary mouth opener comprises an upper jaw cover, a headband is fixedly connected to the upper jaw cover, a guide rail is fixedly connected to the upper jaw cover, a bite device is slidably connected to the guide rail, and the bite device comprises a slider, a support column is fixedly connected to the slider, a bite piece is fixedly connected to the support column, and the slider is slidably connected to the guide rail.

[0006] The guide rail is located at the side of the animal mouth, the bite piece extends toward the center of the animal mouth, and the rear part of the guide rail is extended out of the animal mouth, so that the bite piece can be covered at the animal mouth when it is at the rear part of the guide rail.

[0007] The guide rail extends backwards, is parallel to the bottom edge of the upper jaw cover, and the axis of the supporting column is horizontal.

[0008] After the headband is worn on the animal's head, the height of the guide rail is lower than the bottom of the upper jaw teeth of the animal.

[0009] The articulator also includes a fastener. An internal threaded hole is arranged on the outer end surface of the slider. The fastener is screwed into the internal threaded hole through threaded matching. The fastener can be pressed against the guide rail.

[0010] There are two articulators arranged in mirror symmetry on the left and right sides.

[0011] The beneficial effects of the veterinary mouth opener of the utility model are:

[0012] Among them, after the headband is worn on the animal's head, the height of the guide rail is lower than the bottom of the animal's upper jaw teeth, and the bite piece extends toward the center of the animal's mouth to block between the upper and lower rows of teeth and keep the animal's mouth open. The rear part of the guide rail is extended out of the animal's mouth, so that the articulator is detached from the animal's mouth when it is at the rear of the guide rail. The bite piece is located outside the animal's mouth and can be blocked at the animal's mouth, obstructing the animal's mouth and the target to be bitten, thereby achieving bite prevention.

[0022] A kind of veterinary mouth opener, reference Figures 1 to 3 , including an upper jaw cover 1 of an arc-shaped plate structure, the middle part of the upper jaw cover 1 bulges upward, the upper jaw cover 1 is used to cover the upper jaw part of the animal, the bottom edge of the upper jaw cover 1 is arranged close to the upper teeth of the animal, but not lower than the upper teeth, and the upper jaw cover 1 can be made of single-layer or multi-layer cowhide, composite cowhide, metal plate or carbon fiber plate;

[0023] A headband 2 is fixed to the upper jaw cover 1. The headband 2 is of prior art and is one or more of a belt or a braided belt. The headband 2 includes: two horizontally extending connecting belts I extending toward the neck of the animal, the rear ends of the two connecting belts I are respectively fixed to the left and right ends of the upper jaw cover 1, and also includes a connecting belt II that is sleeved on the neck of the animal, the front ends of the two connecting belts I are respectively fixed to the left and right ends of the connecting belt II, the connecting belt I and / or the connecting belt II can imitate the structure of a waist belt to achieve size changes, the headband 2 also includes a connecting belt III attached to the top of the animal's head, the two ends of the connecting belt III are respectively fixed to the upper end of the connecting belt II and the upper part of the upper jaw cover 1, the connection scheme of the connecting belt III can use Velcro to achieve detachable connection, and the connection position can be changed to achieve size changes.

[0024] To further illustrate, two guide rails 3 are fixedly connected to the upper jaw cover 1, and the two guide rails 3 are respectively located on two sides of the animal mouth, that is, the animal mouth is located between the two guide rails 3, and an articulator is slidably connected to each guide rail 3;

[0025] Further explanation, combined with Figure 5 The articulator includes a slider 4, a support column 5 is fixedly connected to the slider 4, a bite piece 6 is fixedly connected to the support column 5, the slider 4 is slidably connected to the guide rail 3 by being plugged into the guide rail 3, and the slider 4 can only slide forward and backward; the guide rail 3 extends to the rear side, the guide rail 3 is parallel to the bottom edge of the upper jaw cover 1, and the axis of the support column 5 is horizontal;

[0026] Among them, after the headband 2 is worn on the animal's head, the height of the guide rail 3 is lower than the bottom of the animal's upper jaw teeth, and the bite piece 6 extends toward the center of the animal's mouth to block between the upper and lower rows of teeth and keep the animal's mouth open. The rear part of the guide rail 3 is extended out of the animal's mouth, so that the bite device is separated from the animal's mouth when it is at the rear of the guide rail 3. The bite piece 6 is located outside the animal's mouth and can be blocked at the animal's mouth, blocking the animal's mouth and the bitten target, thereby achieving anti-bite;
