Description

Technical Field

[0001] This utility model relates to the field of water bath sterilizer technology, specifically to an improved active temperature probe for a water bath sterilizer. Background Technology

[0002] A water bath sterilizer is a device specifically designed for the high-temperature sterilization of pharmaceuticals. It utilizes high-temperature circulating water as the sterilization medium, spraying water to evenly heat the items, causing the proteins of microorganisms to denature and inactivate, thus killing bacteria, spores, and viruses. To strictly control the temperature inside the sterilizer, a temperature probe is required, typically a PT100 resistance temperature sensor. The probe is secured by clamps, and the end of the welded tube of the clamp is then welded to the inner wall of the water bath sterilizer. With this method of fixation, adjusting the position and angle of the probe requires loosening the clamps and rotating the entire probe; it also prevents rotation of the probe relative to the welded tube, resulting in limited flexibility and inconvenience. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an improved movable temperature probe for a water bath sterilizer that allows the probe to rotate relative to the connection point with the water bath sterilizer, thereby adjusting the angle.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] An improved active temperature probe for a water bath sterilizer, the key technology of which includes:

[0006] A temperature probe, comprising a metal protective tube and a probe disposed at one end of the metal protective tube;

[0007] A pipe clamp, comprising a movable clamping body and a fixed clamping body for clamping the metal protective pipe, wherein a clamping body sleeve is provided on one side of the fixed clamping body;

[0008] The regulator includes a base plate fixed on the inside of a water bath sterilizer, a support tube disposed on the base plate, a variable diameter section disposed at one end of the support tube, and a sliding sleeve slidably disposed on the support tube. A compression spring is disposed between the sliding sleeve and the base plate. After the clamping sleeve is rotated and disposed on the variable diameter section, the compression spring drives the sliding sleeve to press against the clamping sleeve to limit the rotation of the tube clamp.

[0009] In one embodiment of this utility model, the end of the clamp sleeve is sequentially connected with a reduced diameter hole and a rotating hole, wherein the diameter of the reduced diameter hole is smaller than the diameter of the rotating hole.

[0010] The variable diameter section includes a variable diameter boss disposed on the end of the support tube, and the variable diameter boss is provided with a variable diameter groove through the middle of the support tube.

[0011] After the variable diameter boss abuts against the edge of the reduced diameter hole, it undergoes elastic deformation, causing the two sides of the variable diameter groove to come together, thereby reducing the distance between the edges of the variable diameter boss to pass through the reduced diameter hole; after the variable diameter boss enters the rotating hole, the distance between the variable diameter grooves is restored, allowing the clamping sleeve to be rotatably mounted on the variable diameter part.

[0012] In one embodiment of this utility model, the edge of the variable diameter boss is provided with a chamfer structure, so that when the variable diameter boss abuts against the edge of the reduced diameter hole, the variable diameter boss receives radial pressure and thus reduces the diameter.

[0013] As one embodiment of this utility model, the support tube is provided with a slide hole in the axial direction, and the support tube is provided with a through long pin hole in the radial direction, and the slide hole passes through the variable diameter boss.

[0014] A sliding column is slidably disposed in the slide hole, and a pin is inserted through one end of the sliding column. The pin passes through the pin through hole and is connected to the sliding sleeve, thereby restricting the rotation of the sliding sleeve and allowing the sliding column and the sliding sleeve to slide synchronously.

[0015] In one embodiment of this utility model, when the sliding sleeve slides to one end of the support tube, one end of the sliding column protrudes from the end of the variable diameter boss.

[0016] The clamping sleeve is rotatably mounted on the variable diameter part, and after the sliding sleeve abuts against the clamping sleeve, one end of the sliding column is located inside the variable diameter boss, thereby supporting the variable diameter boss and preventing the variable diameter boss from shrinking in diameter.

[0017] In one embodiment of this utility model, the end of the sliding sleeve is provided with an annular flange portion, the flange portion is provided with an end face tooth structure, and the end of the clamping sleeve is provided with an end face tooth structure corresponding to the flange portion. The flange portion abuts against the clamping sleeve, and the two end face tooth structures mesh with each other, thereby restricting the rotational movement of the clamping sleeve relative to the support tube.

[0018] As one embodiment of this utility model, the sliding sleeve is symmetrically provided with two protruding ears.

[0019] The beneficial effects of adopting the above technical solution are as follows:

[0020] The temperature probe of this invention is clamped and connected by a pipe clamp, which is detachably mounted on the support tube of the regulator. A sliding sleeve driven by a compression spring can press the clamp body sleeve, thereby restricting the rotation of the pipe clamp. During operation, pressing the sliding sleeve moves it away from the clamp body sleeve, allowing the pipe clamp to rotate relative to the support tube. After adjusting to a suitable angle, releasing the sliding sleeve causes it to press against the clamp body sleeve, thus fixing the pipe clamp and temperature probe at the appropriate angle. This achieves full rotational adjustment of the temperature probe relative to the support tube, providing a more flexible angle adjustment method and convenient operation.

[0032] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0033] First, existing pipe clamps can be found in [reference]. Figure 6 The welded tube at its lower end is used to weld to the inner wall of the water bath sterilizer. With this structural design, it is impossible to rotate the temperature probe relative to the welded tube.

[0034] See Figures 1 to 5 In this embodiment, the improved water bath sterilizer uses an active temperature probe with the following structure designed to achieve the overall rotation function of the temperature probe relative to the support structure: temperature probe 100, tube clamp 200 and regulator 300.

[0035] Among them, see Figure 1 and Figure 2 The temperature probe 100 includes a metal protective tube 101 and a probe 102 disposed at one end of the metal protective tube 101. The other end of the metal protective tube 101 is a wire 103 for wire harness connection.

[0036] See Figures 3 to 5 The pipe clamp 200 includes a movable clamp 201 and a fixed clamp 202 for clamping the metal protective pipe 101. A clamp sleeve 204 is provided on one side of the fixed clamp 202. One end of the movable clamp 201 is hinged to the fixed clamp 202, and the other end of the fixed clamp 202 is connected to the other end of the movable clamp 201 via a through bolt assembly, thereby clamping the metal protective pipe 101. The movable clamp 201 and the fixed clamp 202 have arc-shaped structures corresponding to the metal protective pipe 101 to adapt to its contour.

[0037] See Figure 3 and Figure 4 The regulator 300 includes a base plate 302 fixed to the inside of the water bath sterilizer, a support tube 303 disposed on the base plate 302, a variable diameter portion disposed at one end of the support tube 303, and a sliding sleeve 305 slidably disposed on the support tube 303. A compression spring 304 is disposed between the sliding sleeve 305 and the base plate 302. After the clamping sleeve 204 is rotated onto the variable diameter portion, the compression spring 304 drives the sliding sleeve 305 to press against the clamping sleeve 204 to restrict the rotation of the pipe clamp 200. In this embodiment, a threaded shaft 301 is provided at one end of the base plate 302 for threaded connection with a nut post disposed on the inside of the water bath sterilizer. Two lugs 305-3 are symmetrically provided on the sliding sleeve 305 to facilitate the operator to press the sliding sleeve 305.

[0038] See Figure 4 and Figure 5 The end of the clamp sleeve 204 is sequentially connected to a reducing hole 204-1 and a rotating hole 204-2, the diameter of the reducing hole 204-1 being smaller than the diameter of the rotating hole 204-2.

[0039] The variable diameter section includes a variable diameter boss 306 disposed on the end of the support tube 303, and a variable diameter groove 307 is provided through the middle of the support tube 303 on the variable diameter boss 306.

[0040] After the variable diameter boss 306 abuts against the edge of the reduced diameter hole 204-1, it undergoes elastic deformation, causing the two sides of the variable diameter groove 307 to come together. This reduces the distance between the edges of the variable diameter boss 306, allowing it to pass through the reduced diameter hole 204-1. After the variable diameter boss 306 enters the rotating hole 204-2, the distance between the variable diameter grooves 307 returns to normal, allowing the clamping sleeve 204 to rotate and be mounted on the variable diameter section. At this time, the sliding sleeve 305, driven by the compression spring 304, abuts against the end of the clamping sleeve 204, causing the inner side of the reduced diameter hole 204-1 to abut against the variable diameter boss 306. This utilizes the friction between the surfaces to restrict the rotation of the clamping body 200 relative to the support tube 303.

[0041] See Figure 3 and Figure 4 The variable diameter boss 306 has a chamfered edge, so that when the variable diameter boss 306 abuts against the edge of the reduced diameter hole 204-1, the variable diameter boss 306 receives radial pressure and thus reduces its diameter.

[0042] See Figure 4 and Figure 5 The support tube 303 has an axially oriented slide hole 303-1 and a radially extending through-hole 303-2 for a pin. The slide hole 303-1 passes through the variable diameter boss 306. A sliding column 305-1 is slidably disposed within the slide hole 303-1. One end of the sliding column 305-1 is fitted with a pin 305-2. The pin 305-2 passes through the pin through-hole 303-2 and connects to the sliding sleeve 305, thereby restricting the rotation of the sliding sleeve 305 and allowing the sliding column 305-1 to slide synchronously with the sliding sleeve 305. When the sliding sleeve 305 slides to one end of the support tube 303, one end of the sliding column 305-1 protrudes from the end of the variable diameter boss 306. The clamp sleeve 204 is rotatably mounted on the variable diameter part, and after the sliding sleeve 305 abuts against the clamp sleeve 204, one end of the sliding column 305-1 is located inside the variable diameter boss 306, thereby supporting the variable diameter boss 306 and preventing the variable diameter boss 306 from shrinking when the sliding sleeve 305 abuts against the clamp sleeve 204, thus avoiding the problem of the clamp sleeve 204 detaching from the support tube 303.

[0043] See Figures 1 to 4The sliding sleeve 305 has an annular flange 305-4 at its end. The inner diameter of the flange 305-4 is larger than the edge size of the reducing boss 306, so that the end of the flange 305-4 is flush with the end of the reducing boss 306 after the sliding sleeve 305 has slid into place. The flange 305-4 has an end face tooth structure, and the end of the clamping sleeve 204 has an end face tooth structure corresponding to the flange 305-4. The flange 305-4 abuts against the clamping sleeve 204, and the two end face tooth structures mesh, thereby restricting the rotation of the clamping sleeve 204 relative to the support tube 303.
