Description

Technical Field

[0001] This utility model belongs to the field of dental testing instrument technology, specifically relating to a pulp temperature tester. Background Technology

[0002] The dental pulp temperature tester is a clinical testing method that assesses the vitality of dental pulp through cold and hot stimuli. It is one of the methods for testing the vitality of dental pulp. Its core principle is to observe the reaction of dental pulp nerves by using temperature changes. Specifically, it can be divided into two categories: cold test method and hot test method.

[0003] Currently available pulp temperature testing devices are basically composed of a testing device body and a heat-conducting rod inserted into the testing device body. When the testing device is not in use, in order to prevent damage to the heat-conducting rod, the heat-conducting rod is pulled out of the testing device and then plugged back in for the next use. This not only requires temporary assembly each time it is used, making it inconvenient to use immediately, but also means that the heat-conducting rod may be lost.

[0004] Therefore, it is necessary to provide a pulp temperature tester to address the aforementioned technical issues.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a pulp temperature tester that solves the problem of inconvenience in using existing pulp temperature testers.

[0007] To achieve the above objectives, a specific embodiment of the present invention provides a dental pulp temperature tester, comprising: a tester body and a folding device;

[0008] The detector body is provided with a display panel and a switch. A storage box is slidably disposed on the detector body. A rotating plate is rotatably disposed inside the storage box. Multiple pairs of claws are installed on the rotating plate.

[0009] The folding device is mounted on the detector body. The folding device includes a connecting body. A pair of fixed shafts are fixed inside the detector body. The connecting body rotates on the pair of fixed shafts. A heat-conducting rod is mounted on the connecting body. A groove is carved on the detector body. The heat-conducting rod is placed in the groove. A pair of second contact bodies are mounted inside the connecting body. A pair of first contact bodies corresponding to the second contact bodies are mounted on the connecting body. A plug rod is slidably disposed inside the detector body. A pair of slots are carved on the connecting body. The end of the plug rod near the connecting body is inserted into the slot.

[0010] In one or more embodiments of this utility model, a pair of slide rails are cut into the body of the detector, and a pair of sliders are fixed on the storage box. The pair of sliders slide within the pair of slide rails, thereby enabling the storage box to slide on the body of the detector.

[0011] In one or more embodiments of this utility model, a slot is chiseled in the inner wall of the detector body, and an elastic buckle is fixed on the storage box. The elastic buckle is engaged in the slot, thereby securing the storage box to the detector body.

[0012] In one or more embodiments of this utility model, a pair of sliding grooves are cut into the storage box, and a push plate is fixed inside the detector body. The push plate passes through the pair of sliding grooves and is located at the bottom of the rotating plate. When the storage box is pulled outward, the push plate slides at the bottom of the rotating plate, causing the rotating plate to rotate, thereby lifting the outward end of the rotating plate, which makes it convenient to pick up the heat-conducting rod stuck on the claw.

[0013] In one or more embodiments of this utility model, multiple pairs of the claws are used to store heat-conducting rods. Heat-conducting rods of different sizes are clipped onto the claws and stored in a storage box for easy access when in use.

[0014] In one or more embodiments of this utility model, a torsion spring is installed on each of the pair of fixed shafts between the connecting body and the inner wall of the detector body. The torsion provided by the torsion spring is used to drive the connecting body to rotate, so that the connecting body rotates the heat-conducting rod out of the groove.

[0015] In one or more embodiments of this utility model, a circular groove and a clamping groove are formed in the connecting body. The inner diameter of the clamping groove is smaller than the inner diameter of the circular groove. A pushing block is installed on the connecting body. The pushing block slides on the circular groove. When the pushing block drives the clamping gripper to be clamped in the clamping groove, since the inner diameter of the clamping groove is smaller than the inner diameter of the circular groove, the clamping gripper tightens the heat-conducting rod, thereby clamping the heat-conducting rod in the connecting body.

[0016] In one or more embodiments of this utility model, a plurality of clamping claws are fixed at one end of the pushing block located in the annular sliding groove. The clamping claws are engaged in the clamping groove. The pushing block clamps the heat-conducting rod in the connecting body by pushing the clamping claws into the clamping groove.

[0017] In one or more embodiments of this utility model, the insertion rod is externally fixed with a push block, which is used to drive the insertion rod to move so that the insertion rod is moved out of the slot.

[0018] In one or more embodiments of this utility model, a spring is installed between the insertion rod and the inner wall of the detector body. The spring force is used to push the insertion rod to move towards the connector, so that the end of the insertion rod is inserted into the slot.

[0019] Compared with the prior art, this utility model can effectively solve the problem of improving the ease of use of the pulp temperature tester through relevant structural design. Attached Figure Description

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0034] like Figure 1-10 As shown, the pulp temperature tester in one embodiment of the present invention includes: a tester body 1 and a folding device 2.

[0035] like Figure 1-5 As shown, the detector body 1 is equipped with a display panel 101 and a switch 102. A storage box 103 is slidably mounted on the detector body 1. The storage box 103 is used to store other heat-conducting rods 202 of different models for easy access during use. A rotating plate 108 is rotatably mounted inside the storage box 103. Multiple pairs of claws 109 are installed on the rotating plate 108. When the storage box 103 is pulled out of the detector body 1, the outer end of the rotating plate 108 is lifted upward, thereby lifting the heat-conducting rod 202 placed on the rotating plate 108 out of the storage box 103 for easy access. The claws 109 clamp the heat-conducting rod 202 onto the rotating plate 108 to prevent the heat-conducting rod 202 from swinging back and forth inside the storage box 103 and causing damage to the heat-conducting rod 202.

[0036] like Figure 1-5As shown, a pair of slide rails 104 are carved inside the detector body 1, and a pair of sliders 105 are fixed on the storage box 103. The pair of sliders 105 slide within the pair of slide rails 104, thereby enabling the storage box 103 to slide onto the detector body 1. A slot 106 is carved into the inner wall of the detector body 1, and an elastic buckle 107 is fixed on the storage box 103. The elastic buckle 107 is engaged within the slot 106, thereby securing the storage box 103 onto the detector body 1.

[0037] like Figure 1-5 As shown, a pair of sliding grooves 111 are carved into the storage box 103. A push plate 110 is fixed inside the detector body 1. The push plate 110 passes through the pair of sliding grooves 111 and is located at the bottom of the rotating plate 108. When the storage box 103 is pulled outward, the push plate 110 slides at the bottom of the rotating plate 108, causing the rotating plate 108 to rotate. This lifts the outward-facing end of the rotating plate 108, making it easier to retrieve the heat-conducting rod 202 that is held in the claw 109. Multiple pairs of claws 109 are used to store the heat-conducting rod 202. Heat-conducting rods 202 of different sizes are held in the claws 109 and stored in the storage box 103 for easy retrieval during use.

[0038] like Figure 6-10 As shown, the folding device 2 is installed on the main body 1 of the detector. The folding device 2 includes a connecting body 201. A pair of fixed shafts 204 are fixed inside the main body 1. The connecting body 201 rotates on the pair of fixed shafts 204. The connecting body 201 is used to connect the heat-conducting rod 202. At the same time, the rotation of the connecting body 201 drives the heat-conducting rod 202 to rotate. The heat-conducting rod 202 is installed on the connecting body 201. A groove 203 is carved on the main body 1. The heat-conducting rod 202 is placed in the groove 203. When the instrument is no longer in use, the connecting body 201 drives the heat-conducting rod 202 to rotate into the groove 203 to prevent damage to the heat-conducting rod 202. At the same time, folding reduces the length of the instrument, making it convenient for storage.

[0039] like Figure 6-10As shown, a pair of second contact bodies 207 are installed inside the connector 201, and a pair of first contact bodies 206 corresponding to the second contact bodies 207 are installed on the connector 201. When using this device, the connector 201 drives the heat-conducting rod 202 to rotate and open from the detector body 1. After opening, the second contact bodies 207 and the first contact bodies 206 come into contact with each other, thereby transferring heat energy to the heat-conducting rod 202 through the connector 201. A plug rod 208 is slidably arranged inside the detector body 1, and a pair of slots 211 are carved on the connector 201. One end of the plug rod 208 near the connector 201 is inserted into the slot 211. By inserting the end of the plug rod 208 near the connector 201 into the slot 211, the connector 201 is stabilized and cannot be rotated. The positions of the pair of slots 211 correspond to the positions where the heat-conducting rod 202 is folded in the groove 203 and the positions where the heat-conducting rod 202 is opened for use.

[0040] like Figure 6-10 As shown, a pair of fixed shafts 204 are each equipped with a torsion spring 205 between the connecting body 201 and the inner wall of the detector body 1. The torsion provided by the torsion spring 205 is used to drive the connecting body 201 to rotate, so that the connecting body 201 rotates the heat-conducting rod 202 out of the groove 203. The connecting body 201 has a circular slide groove 214 and a clamping groove 215. The inner diameter of the clamping groove 215 is smaller than the inner diameter of the circular slide groove 214. A push block 212 is installed on the connecting body 201. The push block 212 slides on the circular slide groove 214. When the push block 212 drives the clamping gripper 213 to be engaged in the clamping groove 215, since the inner diameter of the clamping groove 215 is smaller than the inner diameter of the circular slide groove 214, the clamping gripper 213 tightens the heat-conducting rod 202, thereby clamping the heat-conducting rod 202 in the connecting body 201.

[0041] like Figure 6-10 As shown, a plurality of clamping claws 213 are fixed at one end of the push block 212 located within the annular slide groove 214. The clamping claws 213 are engaged in the clamping groove 215. The push block 212 clamps the heat-conducting rod 202 into the connector 201 by pushing the clamping claws 213 into the clamping groove 215. A push block 210 is fixed to the outside of the detector body 1 for the insertion rod 208. The push block 210 is used to move the insertion rod 208, causing the insertion rod 208 to move out of the slot 211. A spring 209 is installed between the insertion rod 208 and the inner wall of the detector body 1. The elastic force of the spring 209 is used to push the insertion rod 208 towards the connector 201, so that the end of the insertion rod 208 is inserted into the slot 211.

[0042] Working principle: When using this device, first push the push block 210 away from the connector 201. The push block 210 drives the insertion rod 208 out of the slot 211, so that the insertion rod 208 is no longer stuck in the connector 201. Then, the torque of the torsion spring 205 drives the connector 201 to rotate. The connector 201 drives the heat-conducting rod 202 out of the groove 203 and rotates to the open state. Then, after releasing the push block 210, the elastic force of the spring 209 pushes the insertion rod 208 towards the connector 201, pushing the end of the insertion rod 208 into another slot 211, thereby locking the connector 201. Then, this device can be used for testing.

[0043] When it is necessary to replace the heat conduction rod 202 with a different model, first pull out the storage box 103. While the storage box 103 moves the rotating plate 108 outward, the push plate 110 slides along the bottom of the rotating plate 108, causing the rotating plate 108 to rotate. This causes the outer end of the rotating plate 108 to lift upward. As the rotating plate 108 moves the heat conduction rod 202, which is clamped on the claw 109, upward, one end of the rotating plate 108 lifts upward. The push plate 110 slides from one end of the slide groove 111 to the other end. Then the heat conduction rod 202 on the claw 109 can be removed. Then the heat conduction rod 202 inserted into the connector 201 is pulled out. When the heat conduction rod 202 is pulled outward, the heat conduction rod 202 causes the clamping claw 213 to move from the clamping groove 215 to the annular slide groove 214. After that, the clamping claw 213 no longer clamps the heat conduction rod 202. At this time, the heat conduction rod 202 can be pulled out.

[0044] Then, insert another type of heat-conducting rod 202 into the push block 212. After inserting it a certain distance, the protective shell on the heat-conducting rod 202 pushes the push block 212 to move. The push block 212 drives the clamping gripper 213 to move. When the heat-conducting rod 202 drives the clamping gripper 213 from the annular slide groove 214 into the clamping groove 215, the clamping gripper 213 clamps the heat-conducting rod 202 onto the connector 201, thus completing the installation of the heat-conducting rod 202. Then, put the replaced heat-conducting rod 202 into the groove 203 and push the groove 203 into the detector body 1.
