Description

Technical Field

[0001] This utility model relates to an oral cavity retractor, and more particularly to an animal oral cavity retractor. Background Technology

[0002] An oral retractor is an instrument used to open the mouth. It is used during oral treatment in animals to prevent the animal's mouth from interfering with the veterinarian's work.

[0003] For example, Chinese Patent Publication No. CN219835709U discloses an animal oral retractor that solves the problem that most existing oral retractors cannot compress the animal's tongue, causing the tongue to move and affecting veterinarians' oral examinations or medication administration. The animal oral retractor includes two mounting plates. A cylinder is fixedly connected to the lower mounting plate, passing through the upper mounting plate and slidably connected to it. The two mounting plates are elastically connected by a spring. Each mounting plate has a tooth storage groove for accommodating animal teeth. A rotating component is provided on the lower mounting plate to compress the animal's tongue. This invention effectively compresses the animal's tongue, preventing tongue movement from interfering with veterinarian operations.

[0004] Some problems have been found when using the existing animal oral retractor. First, the device needs to be inserted into the animal's mouth. Animals that need treatment are often sick and their mouths may contain a large number of bacteria. If the device is inserted directly into the animal's mouth, it will be contaminated with a large number of bacteria. Second, it is difficult to clean and disinfect components such as the tongue depressor later. Utility Model Content

[0005] The purpose of this invention is to provide an animal oral cavity opener to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an animal oral cavity opener, comprising two connecting seats, a telescopic connecting rod fixedly connected between the two connecting seats, an extension connecting member fixedly connected to the rear of the connecting seats, a first bidirectional screw fixedly connected to the top of the extension connecting member, two sliders symmetrically threaded on the first bidirectional screw, a hook fixedly connected to the protruding edge of one side of the slider, an opening cloth provided between the two sides of the slider, and eyelets embedded in the opening cloth near the two side edges, the eyelets cooperating with the hooks.

[0007] Preferably, a first knob is fixedly connected to the upper end of the first bidirectional screw.

[0008] Preferably, the telescopic connecting rod includes a second bidirectional screw and a threaded sleeve, one end of which is fixedly connected to the connecting seat, and the other end of which is threadedly engaged with the second bidirectional screw.

[0009] Preferably, a second knob is fixedly connected to the second bidirectional screw.

[0010] Preferably, a threaded sleeve is embedded in the slider, and the threaded sleeve is threadedly engaged with the first bidirectional screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By using the hook and eyelet to work together, after reducing the distance between the two first bidirectional screws, the stretching cloth is in a relaxed state, which makes it easy to remove the stretching cloth that is in contact with the animal's mouth, making it convenient to clean and disinfect the stretching cloth.

[0013] 2. By using a softer fabric to stretch the cloth, damage to the internal structures of the animal's mouth can be minimized when it comes into contact with the oral cavity.

[0014] 3. The connecting seat is rotatably connected to the first bidirectional screw through the extension connector, so that the spreading cloth and the telescopic connecting rod are vertically offset, so as to avoid interference between the animal's lower jaw and the telescopic connecting rod during the downward movement of the lower spreading cloth.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an animal oral cavity opener, including two connecting seats 1, a telescopic connecting rod 2 fixed between the two connecting seats 1, an extension connecting member 101 fixed to the rear of the connecting seats 1, a first bidirectional screw 102 fixed to the extension connecting member 101, two sliders 3 symmetrically threaded on the first bidirectional screw 102, a hook 302 fixed to the protruding edge of one side of the slider 3, an opening cloth 4 between the two sliders 3, and eyelets 401 embedded in the opening cloth 4 near the two side edges, the eyelets 401 and the hooks 302 cooperating with each other.

[0022] In this embodiment, by designing the hook 302 to be curved outwards, the fabric 4 is stretched and taut. The eyelet 401 then engages with the hook 302, connecting the stretched fabric 4 to the slider 3. At this point, the stretched fabric 4 is difficult to remove. The two stretched fabrics 4 are inserted into the animal's mouth. Adjusting the distance between the two sliders 3 on the same first bidirectional screw 102 causes the sliders 3 to move, thus adjusting the distance between the stretched fabrics 4. The two stretched fabrics 4 move further apart, thereby opening the animal's mouth. The stretched fabrics 4 are made of a relatively soft material. Firstly, when in contact with the internal tissues of an animal's mouth, damage to the internal components of the mouth can be minimized. Secondly, the stretching cloth 4 is secured to the hook 302 using the corn eyelet 401. After use, the telescopic connecting rod 2 can be shortened to reduce the distance between the connecting seats 1. The connecting seats 1 will drive the first bidirectional screw 102 to move, thereby reducing the distance between the two side sliders 3. At this time, the stretching cloth 4 will be in a relaxed state, and the corn eyelet 401 can be easily removed from the hook 302. The stretching cloth 4 can then be removed separately for cleaning, avoiding the problem of excessive bacteria on the stretching cloth 4 later, which makes it difficult to clean and disinfect.

[0023] In order to achieve the purpose of adjusting the distance between the connecting seats 1, the device adopts the following technical solution: the upper end of the first bidirectional screw 102 is fixedly connected to the first knob 103, the telescopic connecting rod 2 includes the second bidirectional screw 201 and the threaded sleeve 202, one end of the threaded sleeve 202 is fixedly connected to the connecting seat 1, and the other end of the threaded sleeve 202 is threadedly engaged with the second bidirectional screw 201.

[0024] The first knob 103 can drive the first bidirectional screw 102 to rotate. The second bidirectional screw 201 is threadedly engaged with the threaded sleeve 202. Rotating the second bidirectional screw 201 can drive the threaded sleeve 202 to move. The movement of the threaded sleeve 202 will drive the connecting seat 1 to move, thereby adjusting the distance between the two connecting seats 1.

[0025] In order to achieve the purpose of adjusting the spacing between the spread fabrics 4, the device adopts the following technical solution: a second knob 203 is fixedly connected to the second bidirectional screw 201, and a threaded sleeve 301 is embedded in the slider 3, which is threadedly engaged with the first bidirectional screw 102.

[0026] The second knob 203 can be used to drive the second bidirectional screw 201 to rotate. The threaded sleeve 301 is threadedly engaged with the first bidirectional screw 102, thereby threading the slider 3 onto the first bidirectional screw 102. Rotating the first bidirectional screw 102 can adjust the distance between the two sliders 3, thereby adjusting the distance between the spread fabrics 4.

[0027] The working principle and usage process of this utility model are as follows: When using it, the two sliders 3 located on the same first bidirectional screw 102 need to be brought close to each other so that the two stretching cloths 4 are as close together as possible. Then, the two stretching cloths 4 are inserted into the animal's mouth. At the same time, the first knob 103 is rotated to drive the two first bidirectional screws 102 to rotate. The rotation of the first bidirectional screws 102 will drive the sliders 3 to move, thereby adjusting the distance between the stretching cloths 4. As the distance between the stretching cloths 4 increases, the animal's mouth will gradually open. After use, the second knob 203 can be used to drive the second bidirectional screw 201 to rotate, which will drive the two connecting seats 1 to move close to each other. The movement of the connecting seats 1 will drive the sliders 3 on both sides to move close to each other, thereby making the stretching cloths 4 in a relaxed state. At this time, the corn buckle 401 can be easily removed from the hook 302, and the stretching cloth 4 that has been in contact with the animal's mouth can be removed separately for easy cleaning and disinfection.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
