[0002] Existing electronic thermometers are mostly composed of the following structure: a shell, a temperature sensing probe is connected to the front of the shell, the rear of the shell is open and has an opening, the rear is connected to a cap body by plug-in fitting, and the core module for temperature measurement can be installed in the shell through this opening.

[0003] Most electronic thermometers on the market are provided with an annular contraction portion at the rear of the shell, on which are opened several annular protrusions, and an annular groove matching with the annular protrusions is provided in the cap body. When the cap body and the shell body are plugged together, the annular protrusion will be stuck in the annular groove; this design is for the convenience of users to repair the movement module or replace the battery, and the entire movement module can be taken out by simply unplugging the cap body; but the existing electronic thermometers only clamp the battery through the buckle of the battery installation slot in the movement module, so that children without cognitive ability can easily pull off the cap body and pick out the button battery and swallow it by mistake. Summary of the invention

[0004] In order to solve the above-mentioned technical problems, the purpose of the utility model is to provide an electronic thermometer, which connects the shell and the cap body through a connecting plate, and then fixes the connecting plate to the shell with screws. The connecting plate can effectively prevent the cap body from falling off the shell, reducing the possibility of children pulling off the cap body and contacting the button battery, thereby further improving safety.

[0005] The technical solution of the utility model is achieved in this way:

[0008] Preferably, the connecting plate is in the shape of an I-beam as a whole, and the connecting plate includes a connecting plate body and limiting parts extending in the width direction at both ends of the connecting plate body; a first T-shaped slot is provided at the rear end of the shell, and a second T-shaped slot is provided at the cap body; the first T-shaped slot is composed of a first limiting slot and a first vertical slot, the first limiting slot extends along the width direction of the shell, one end of the first vertical slot is connected to the middle of the first limiting slot, and the other end is connected to the rear end of the shell; the second T-shaped slot is composed of a second limiting slot and a second vertical slot, the second limiting slot extends along the width direction of the cap body, one end of the second vertical slot is connected to the middle of the second limiting slot, and the other end is connected to the rear end of the cap body; when the cap body is plugged into the shell, the first T-shaped slot and the second T-shaped slot are combined into an I-shaped slot; when the connecting plate is installed, the connecting plate is embedded in the I-shaped slot as a whole; the connecting plate is an I-shaped plate that is integrally injection molded, has a simple structure, and is easy to mold. The cap body and the shell are also made by integral injection molding, and there is no need to add a process for the slot body.

[0009] Preferably, the two limiting portions of the connecting plate are respectively embedded in the first limiting groove and the second limiting groove, and the connecting plate is hung on the shell and the cap body by limiting the two limiting portions of the connecting plate in the first limiting groove and the second limiting groove respectively; the limiting portion at one end of the connecting plate is hung in the second limiting groove of the cap body, and the limiting portion at the other end of the connecting plate is hung in the first limiting groove of the shell. When the electronic thermometer receives a pulling force from the cap body and the shell, the connecting plate can limit the movement of the cap body or the shell in the direction of the pulling force, thereby limiting the cap body from falling off.

[0010] Preferably, the limiting portion of the connecting plate is not higher than the outer surfaces of the shell and the cap body, so that the transition between the connecting plate and the shell and the cap body is smooth and more beautiful.

[0011] Preferably, the first limiting groove and the first vertical groove are sunken grooves, the connecting plate body is provided with via holes and through holes, the corresponding positions of the shell are provided with threaded holes, and the connecting plate is fixedly connected to the shell by screws after being installed in place.

[0012] Preferably, the through hole is a countersunk hole for accommodating the screw head, and the screw head is hidden by the through hole so that it does not protrude from the surface of the connecting plate.

[0013] Preferably, the rear end of the shell is provided with a contraction portion that is plugged into and cooperates with the cap body, and the contraction portion is provided with a first annular groove for accommodating a sealing ring, and a second annular groove that cooperates with the sealing ring is provided on the inner side of the cap body; the first annular groove is located at the rear end of the shell, and a distance is left between it and the first T-slot in the direction of the temperature sensing head, and the two do not intersect with each other; in order to achieve the hanging effect of the connecting plate on the cap body and the shell, a first T-slot is opened at the opening of the shell, and at the same time, a first annular groove is preset on the outer wall of the shell near one end of the shell opening for cooperation with the sealing ring, and in order to simultaneously achieve the hanging effect of the connecting plate on the cap body and the shell and the waterproof effect of the sealing ring, a distance is left between the first annular groove and the first T-slot, and the two do not intersect with each other.

[0014] Preferably, the cap brim of the cap body has two convex teeth protruding forward with symmetrical intervals, the second limiting groove is arranged between the two convex teeth, and a corresponding avoidance groove matching the convex teeth is arranged on the surface of the shell; when the cap body is plugged into the shell, the convex teeth are embedded in the preset avoidance groove of the shell, and when the cap body is subjected to a pulling force, the convex teeth are stopped by the groove wall of the avoidance groove. The wall thickness of the cap body is mostly very thin. If the second limiting groove is directly hollowed out on the cap body, even if there is a stopping effect of the connecting plate, the cap body is easily deformed and easily separated from the shell when subjected to a large pulling force; and the convex tooth design forms the second limiting groove between the two convex teeth, which is separated from the cap body itself, in order to transfer the deformation force received by the cap body to the convex teeth, and then to the avoidance groove on the surface of the shell, and finally to be borne by the shell, and the shell wall thickness and strength are greater than the cap body, thereby avoiding deformation of the cap body itself and the convex teeth, and avoiding the cap body directly separating from the shell when subjected to a large pulling force; the convex tooth design also avoids the second T-shaped groove and the second annular groove from being interconnected.

[0015] The principle and beneficial effects of the utility model using the above technical solution are:

[0016] 1. The utility model provides an electronic thermometer, which adds a connecting plate as a component, connects the connecting plate with the shell and the cap, and uses screws to fix the connecting plate to the shell, thereby preventing unaware children from directly pulling out the cap and taking out the battery, greatly reducing the possibility of unaware children accidentally swallowing the battery.

[0017] 2. The connecting plate hangs the shell and the cap body together. When the cap body is subjected to a pulling force, the limiting grooves of the shell and the cap body confront the limiting parts of the connecting plate, and the shell and the cap body cannot be separated by pulling.

[0018] 3. Fix the connecting plate to the housing with screws. When you need to replace the battery or repair the movement, just use a screwdriver to unscrew the screws. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0026] The specific implementation of the utility model is as follows:

[0027] See also Figure 1-4 , this embodiment proposes an electronic thermometer, including a shell 2, a temperature sensing probe, a core module, a cap body 1, a connecting plate 3, and a sealing ring 5; the temperature sensing probe is connected to the front end of the shell 2, and the temperature sensing probe is electrically connected to the circuit board on the core module; the focus of the utility model is that the cap body 1 is fixedly connected to the opening at the rear end of the shell 2 through the connecting plate 3, the connecting plate 3 spans the junction between the shell 2 and the cap body 1, and the two ends of the connecting plate 3 are respectively hung on the shell 2 and the cap body 1 to limit the cap body 1 from being pulled out of the shell 2. After the connecting plate 3 is installed in place, it is fixedly connected to at least one of the shell 2 and the cap body 1 through screws 4, that is, the connecting plate can be connected to the shell by screws, the connecting plate can be connected to the cap body by screws, and the connecting plate can also be connected to the cap body and the shell at the same time by screws.

[0028] like Figure 2 As shown, in order to enable the connecting plate to be able to hook the shell and the cap body, the connecting plate 3 is in an I-shape as a whole, and the connecting plate 3 includes a connecting plate body 302 and limiting portions 301 extending in the width direction at both ends of the connecting plate body 302. When the connecting plate 3 is installed and matched with the shell 2 and the cap body 1, the limiting portions 301 can resist the force from the shell 2 and the cap body 1 in the direction of the shell 2 and the cap body 1 on both sides.

[0029] Furthermore, the connecting plate or the limiting groove is not limited to a certain shape. As long as the connecting plate 3 is installed and matched with the limiting groove, the limiting groove can transmit the force from the shell 2 or the cap body 1 along the length direction of the thermometer to form a countermeasure with the limiting portion 301 of the connecting plate 3. Therefore, the limiting groove can be designed as a cuboid, a cylinder with a trapezoidal cross-section, or a cylinder with arc surfaces at both ends, etc. In the present embodiment, the limiting groove is designed as a cylinder with arc surfaces at both ends.

[0030] In this embodiment, reference Figure 1 A first T-shaped groove 201 is provided at the rear end of the shell 2, and a second T-shaped groove 101 is provided at the cap body 1; the first limiting groove 201a extends along the width direction of the shell 2, and the middle part of the first limiting groove 201a is connected to the rear end of the shell 2 through the first vertical groove 201b, so that the first limiting groove 201a and the first vertical groove 201b constitute the first T-shaped groove 201; the second limiting groove 101a extends along the width direction of the cap body 1, and the middle part of the second limiting groove 101a is connected to the rear end of the cap body 1 through the second vertical groove 101b, so that the second limiting groove 101a and the second vertical groove 101b constitute the second T-shaped groove 101; when the cap body 1 is plugged into the shell 2, the first T-shaped groove 201 and the second T-shaped groove 101 are combined into an I-shaped groove; when the connecting plate 3 is installed, the connecting plate 3 is embedded in the I-shaped groove as a whole.

[0031] Specifically, the hanging function of the connecting plate is realized as follows: the limiting parts 301 at both ends of the connecting plate 3 are respectively embedded in the first limiting groove 201a and the second limiting groove 101a, and the connecting plate 3 is hung on the shell 2 and the cap body 1 by limiting the two limiting parts 301 of the connecting plate 3 in the first limiting groove 201a and the second limiting groove 101a respectively; when the electronic thermometer receives a pulling force from the cap body 1 and the shell 2, the second T-shaped groove 101 of the cap body 1 forms an opposition with the limiting part 301 at one end of the connecting plate 3, and the first T-shaped groove 201 of the shell 2 forms an opposition with the limiting part 301 at the other end of the connecting plate, so when an unaware child pulls the cap body, the cap body cannot be removed.

[0032] Furthermore, the limiting portion 301 of the connecting plate 3 is not higher than the outer surfaces of the shell 2 and the cap body 1, so that the transition between the connecting plate 3 and the shell 2 and the cap body 1 is smooth and more beautiful.

[0033] In order to fix the connecting plate to the electronic thermometer in the thickness direction of the thermometer so that it does not fall off, Figure 1 Or 4, after the connecting plate 3 is installed in place, it is fixedly connected to at least one of the shell body 2 and the cap body 1 by screws 4; in this embodiment, the connecting plate body 302 is placed on the shell body 2, and the connecting plate 3 is connected to the shell body 2 by screws 4; in order to support the connecting plate, the first limiting groove 201a and the first vertical groove 201b are sunken grooves; in order to cooperate with the screws, a through hole 303 is provided on the connecting plate body 302, and a threaded hole 203 is provided at the corresponding position of the shell 2.

[0034] Of course, there are other connection methods. For example, the connecting plate body 302 is placed on the cap body 1, and the connecting plate 3 is connected to the cap body 1 by screws 4. In order to support the connecting plate 3, the second limiting groove 101a and the second vertical groove 101b provided on the cap body 1 are recessed grooves. In order to cooperate with the screws 4, the connecting plate body 302 is provided with a through hole 303, and the corresponding position of the cap body 1 is provided with a threaded hole. After the connecting plate 3 is installed in place, it is fixedly connected to the cap body 1 by screws 4; or the shell body 2 and the cap body 1 are both provided with recessed grooves, both supporting the connecting plate 3, that is, the connecting plate 3 is fixedly connected to the shell body 2 and the cap body 1 at the same time. Therefore, the utility model is not limited to connecting and fixing the connecting plate 3 to the shell body 2 or the cap body 1.

[0035] like Figure 3 It can be seen that the through hole 303 is a countersunk hole for accommodating the head of the screw 4. The through hole 303 is used to hide the head of the screw 4 so that it does not protrude from the surface of the connecting plate 3. This can prevent the user from being hit by the screw 4 when holding the electronic thermometer. It can also prevent the head of the screw 4 from scratching or catching the wool of clothes, etc., which is convenient for users to use in daily life.

[0036] like Figure 4 As shown, the rear end of the shell 2 is provided with a contraction portion 205 that is plugged with the cap body 1, and a first annular groove 202 for accommodating the sealing ring 5 is provided on the contraction portion 205, and a second annular groove 103 that cooperates with the sealing ring 5 is provided on the inner side of the cap body 1; after the sealing ring 5 is installed at the groove of the shell 2, the cap body 1 is plugged with the shell 2, and the waterproof effect of the electronic thermometer is achieved to a certain extent; in order to ensure the waterproof sealing effect of the sealing ring 5, the first annular groove 202 is located at the rear end of the shell 2, and a certain distance is left between it and the first T-shaped groove 201 in the direction of the temperature sensing head, and they are not staggered, that is, compared with the first T-shaped groove 201, the first annular groove 202 is closer to the rear end of the shell 2, and the first annular groove 202 and the first T-shaped groove 201 are two separated grooves, so that the first annular groove 202 and the first T-shaped groove 201 are prevented from being connected to each other or the first T-shaped groove 201 is closer to the end of the shell 2, resulting in failure of the sealing ring 5.

[0037] Furthermore, in order to increase the force that the cap can withstand, Figure 1As shown, the cap brim of the cap body 1 protrudes forward with two symmetrically spaced protruding teeth 102, the thickness of the protruding teeth can be set to be thicker than the cap body wall thickness, the second limiting groove 101a is set between the two protruding teeth 102, and the surface of the shell 2 is correspondingly provided with an avoidance groove 204 matching the protruding teeth 102; when the cap body 1 is plugged into the shell 2, the protruding teeth 102 are embedded in the avoidance groove 204 preset in the shell 2, and when the cap body 1 is subjected to a pulling force, the protruding teeth 102 are stopped by the groove wall of the avoidance groove 204; As the electronic thermometer is small in size and compact in structure, if there is no convex tooth 102 structure, the position of the second T-shaped groove 101 needs to be moved toward the closed end of the cap body 1. At this time, the second T-shaped groove 101 of the cap body 1 will be connected to the second annular groove 103 on the cap body 1, which will affect the sealing effect of the sealing ring 5. At the same time, the structural design of the convex tooth 102 can prevent the user from pulling the cap body 1 too hard, causing the cap body 1 to deform, and the connecting plate 3 cannot be well hooked on the cap body, so that the cap body 1 falls off the shell 2.

[0038] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
