Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to a disassembly device for the housing of a temperature measuring gun probe connector. Background Technology

[0002] In many applications, the temperature of molten steel (iron) is measured using a contact method. This involves the temperature-sensing element of the temperature-sensing gun directly contacting the molten steel, allowing for sufficient heat exchange between the measured medium and the sensing element, bringing them to the same temperature for measurement. The temperature-sensing gun head consists of a housing and connectors. Because of the contact measurement method, the ambient temperature is very high, and the connectors are prone to thermal expansion. Furthermore, the temperature-sensing gun head is tightly sealed at the factory, making disassembly of the housing difficult, time-consuming, and inefficient for on-site calibration. Prolonged operation in high-temperature environments also poses a high risk of heatstroke for workers.

[0003] Therefore, the difficulty in disassembling the nozzle insert housing of the temperature measuring gun is a problem that urgently needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide a disassembly device for the housing of a temperature gun probe connector. Using this disassembly device to disassemble the housing of the connector can greatly reduce the labor intensity of the workers, save a lot of effort, effectively improve the disassembly efficiency of the connector, and save disassembly time. This can reduce the time that workers spend working in high-temperature environments and help reduce the risk of heatstroke among workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for disassembling the housing of a temperature gun probe connector, comprising:

[0007] A handle that extends along a first direction;

[0008] A locking portion is provided at one end of the handle. The locking portion includes an arc-shaped groove and a locking pin disposed within the arc-shaped groove. The arc-shaped groove is located on the side of the locking portion away from the handle. The arc-shaped groove is used to engage with the outer periphery of the connector housing. The locking portion has an opening communicating with the arc-shaped groove along the arc-shaped extension direction. The arc-shaped groove has a first end and a second end distributed along the arc-shaped extension direction. The locking pin is located at the end of the first end. One end of the locking pin is connected to the arc-shaped concave surface of the arc-shaped groove, and the other end forms a free end. The locking pin is used to pass through and engage with a socket on the connector housing.

[0009] In a plane perpendicular to the axis of the arc-shaped groove: there is a first line connecting the first end and the center of the arc-shaped groove, and a second line connecting the second end and the center of the arc-shaped groove. The angle between the first line and the second line is greater than or equal to 90° and less than or equal to 110° in the direction extending from the first end along the arc-shaped groove to the second end.

[0010] When the above-mentioned disassembly device is applied to the temperature measurement of molten steel (iron), a temperature measuring gun is used. To verify the inner thermocouple connector, the probe's connector housing needs to be removed. During disassembly, the disassembly device described in this embodiment can be used. The worker holds the handle, inserts the locking pin into the connector housing's insertion hole, and engages the arc-shaped locking groove with the circumferential fit of the connector housing. The engaging part "hugs" the outer wall of the connector housing, and the locking pin is inserted into the insertion hole to lock it in place. The worker holds the handle and applies a force perpendicular to the handle's extension direction. Using the lever principle, the engaging part, along with the connector housing, rotates around the connector's axis, thereby unlocking the connection between the connector housing and the connector, allowing the connector housing to be disassembled. This method of disassembling the connector housing significantly reduces the worker's labor intensity, is very labor-saving, effectively improves the disassembly efficiency of the connector, and saves disassembly time. This reduces the time workers spend working in high-temperature environments, thus reducing the risk of heatstroke.

[0011] Optionally, the concave surface of the arc-shaped slot is used to mate with the outer wall surface of the connector housing to form an arc-shaped mating surface, and the arc-shaped mating surface is provided with a micro-serrated anti-slip structure.

[0012] Optionally, the free end of the locking pin faces the axis of the arc-shaped groove, and the axis of the locking pin is perpendicular to the axis of the arc-shaped groove; the dimension of the locking pin along its axis is greater than the wall thickness of the connector housing and less than or equal to the distance between the outer wall of the connector housing and the outer wall of the connector.

[0013] Optionally, the engaging portion is further provided with a tapered post, which is located outside the arc-shaped slot and extends toward the outside of the opening.

[0028] refer to Figure 1 , Figure 2 and Figure 4 As shown, this utility model embodiment provides a disassembly device for the probe connector housing of a temperature measuring gun, used to disassemble the probe connector housing of a temperature measuring gun. The temperature measuring gun 1 has a rod-shaped structure, with a temperature measuring probe at one end. The probe includes an inner coupling head connector 11 and a connector housing 12 sleeved on the outer periphery of the inner coupling head connector 11. There is a certain gap between the connector housing 12 and the inner coupling head connector 11. The inner coupling head connector has a cylindrical structure, and the connector housing is a cylindrical structure. The side wall of the connector housing 12 is provided with… It has a socket 121 that penetrates the side wall of the connector housing 12 and communicates with the interior of the connector housing 12; in the radial direction of the inner head connector, the distance between the connector housing and the inner head connector is generally between 2 mm and 4 mm, specifically 3 mm; the outer diameter of the connector housing is between 14 mm and 18 mm, specifically 15 mm, 15.5 mm or 16 mm; the length of the connector housing in the direction of its axis extension is generally between 40 mm and 50 mm, specifically 45 mm; and the material of the connector housing is brass.

[0029] refer to Figure 3 and Figure 4As shown, the disassembly device 2 for the temperature gun probe connector housing in this embodiment includes: a handle 21 and a locking part 22. The handle 21 extends along a first direction; the locking part 22 is disposed at one end of the handle 21 and connected to one end of the handle 21. The other end and the middle part of the handle 21 form a gripping part for human hand to hold. The locking part 22 includes an arc-shaped groove 221 and a locking pin 222 disposed in the arc-shaped groove 221. The arc-shaped groove 221 is located on the side of the locking part 22 away from the handle 21. The arc-shaped groove 221 is used to engage with... The outer periphery of the connector housing 12 is fitted with an arc-shaped groove that matches the outer wall of the connector housing. The connector housing is cylindrical, and the arc-shaped groove 221 is an arc-shaped groove. The axis of the arc-shaped groove 221 extends along a second direction, which is perpendicular to the first direction. The arc-shaped groove 221 penetrates the engaging portion 22 in the second direction. When the arc-shaped groove 221 is fitted with the connector housing 12, the axis of the arc-shaped groove 221 coincides with the axis of the connector housing 12. It should be noted that the coincidence of the axis of the arc-shaped groove 221 with the axis of the connector housing 12 means that, within the allowable deviation range, their axes can be considered to coincide. The engaging part 22 has an opening communicating with the arc-shaped groove 221 along the arc-shaped extension direction. The arc-shaped groove 221 has a first end and a second end distributed along the arc-shaped extension direction, and the opening is located between the first end and the second end. The locking pin 222 is located at the end of the first end, and one end of the locking pin 222 is connected to the arc-shaped groove 221. The concave surface is curved, and the other end forms a free end. The locking pin 222 is used to pass through the insertion hole 121 on the connector housing 12 and cooperate with the insertion hole 121 on the connector housing 12. The locking pin 222 and the insertion hole are in clearance fit. Preferably, in order to facilitate the insertion of the locking pin 222 into the insertion hole, a rounded chamfer or a straight chamfer is formed between the end face of the free end of the locking pin 222 and the outer wall surface of the locking pin 222. The top edge of the locking pin 222 is chamfered so that a small section of the top edge of the locking pin 222 has a slightly smaller diameter, which makes it easier to insert into the insertion hole.

[0030] Among them, such as Figure 3 As shown, in a plane perpendicular to the axis of the arc-shaped slot 221: there is a first line connecting the first end and the center of the arc-shaped slot 221, and a second line connecting the second end and the center of the arc-shaped slot 221. In the direction extending from the first end along the arc-shaped slot 221 to the second end, the angle θ between the first line and the second line is greater than or equal to 90° and less than or equal to 110°. The angle θ between the first line and the second line can be regarded as the central angle θ of the arc-shaped slot 221. Preferably, the angle θ between the first line and the second line can be set to 90°, 95° or 100°.

[0031] The above-mentioned disassembly device is used before molten steel (iron) temperature measurement. A temperature measuring gun is required for molten steel (iron) temperature measurement. Before the temperature measuring gun is used, the probe's connector housing needs to be removed to verify the inner thermocouple head connector. During disassembly, the disassembly device in this embodiment can be used. The operator holds the handle, and the connector housing is inserted into the arc-shaped groove at the opening. The locking pin is inserted into the insertion hole of the connector housing, and the arc-shaped groove and the connector housing are circumferentially fitted together. The locking part "hugs" the outer wall of the connector housing, and the locking pin is inserted into the insertion hole to lock it in place. By holding the handle and applying a force perpendicular to its extension direction, the operator can utilize the lever principle to rotate the engaging part along with the connector housing around the connector's axis, thereby unlocking the connection between the connector housing and the connector and disassembling the connector housing. This disassembly device significantly reduces the labor intensity of the operator, saving considerable effort and effectively improving the disassembly efficiency of the connector. It also saves disassembly time, thereby reducing the time operators spend working in high-temperature environments and helping to reduce the risk of heatstroke.

[0032] For details, please refer to Figure 3 As shown, the handle 21 and the engaging part 22 can be welded together, or the handle 21 and the engaging part 22 can be a single integrated structure. Both the handle 21 and the engaging part 22 are made of stainless steel. The connection between the handle 21 and the engaging part 22 has a smooth transition, which helps to enhance the connection strength between the handle 21 and the engaging part 22. Specifically, the part where the handle 21 and the engaging part 22 are connected is located between the first end and the second end in the arcuate extension direction of the arcuate groove 221, and one end of the handle 21 is connected to the part of the engaging part 22 near the second end. The engaging part 22 has a local annular structure with a central angle of 90° to 110°, specifically a local annular structure with a central angle of 100°. The inner arc-shaped groove of the local annular structure forms an arc-shaped locking groove 221. In the extension direction of the axis of the local annular structure, the thickness of the engaging part 22 is 5 mm to 10 mm. Specifically, the thickness of the engaging part 22 can be 6 mm or 7 mm, as long as the strength is sufficient. This embodiment is not limited to this.

[0033] For the operating principle of the disassembly device in this embodiment, please refer to... Figure 4 As shown, the connector housing can be snapped into the arc-shaped slot at the opening of the engaging part. The locking pin 222 is inserted into the socket of the connector housing 12. The arc-shaped concave surface on the inner side of the arc-shaped slot 221 fits against the outer periphery of the connector housing. The arc-shaped slot 221 "holds" the connector housing 12. A pressure F perpendicular to the extension direction of the handle 21 is applied to the other end of the handle 21. The locking pin 222 will be locked at the socket. The locking pin 222 will have a tangential force F1 on the side wall of the socket that is tangential to the connector housing. The side wall of the socket is subjected to a tangential force F1, generating torque. The connector housing is rotated under force and is disassembled.

[0034] Specifically, the concave surface of the arc-shaped slot is used to mate with the outer wall surface of the connector housing to form an arc-shaped mating surface. This arc-shaped mating surface is equipped with a micro-serrated anti-slip structure. The micro-serrated anti-slip structure increases the friction between the connector and the outer wall surface, facilitating the twisting of the connector housing.

[0035] refer to Figure 4 As shown, to facilitate gripping and applying force, anti-slip textures are provided on the outer side wall of the handle 21, making it easier for operators to hold and operate. For example, the anti-slip textures can be grid-like protrusions.

[0036] In one possible implementation, such as Figure 3 As shown, the free end of the locking pin 222 faces the axis of the arc-shaped groove 221, and the axis of the locking pin 222 is perpendicular to the axis of the arc-shaped groove 221. The dimension of the locking pin 222 along its axis is greater than the wall thickness of the connector housing and less than or equal to the distance between the outer wall of the connector housing and the outer wall of the connector. The wall thickness of the connector housing is the thickness of the side wall of the connector housing in the radial direction. The length of the locking pin 222 is greater than the wall thickness of the connector housing, which allows it to be well locked at the insertion hole. Applying torque at the insertion hole facilitates the rotation of the connector housing. The length of the locking pin 222 is less than or equal to the distance between the outer wall of the connector housing and the outer wall of the connector to avoid jamming with the connector. Preferably, the length of the locking pin 222 can be set to be less than the distance between the outer wall of the connector housing and the outer wall of the connector.

[0037] Continue to refer to Figure 3 As shown, in the above-mentioned disassembly device, the engaging part 22 is also provided with a conical post 223. The conical post 223 is located outside the arc-shaped slot 221 and extends outward towards the opening. It will not interfere with the engagement between the arc-shaped slot 221 and the connector housing. The conical post 223 can be inserted between the connector housing and the connector at the top of the connector housing to clean debris in the gap between the connector housing and the connector. This can play a certain role in maintaining the temperature gun probe. When disassembling, the conical post 223 is used to clean the gap between the connector housing and the connector to prevent foreign objects from blocking the locking pin 222 from being inserted into the insertion hole. For example, the conical post 223 can be a cylindrical post with a rounded chamfer at the tip. This rounded chamfer at the tip of the cylindrical post makes the tip smooth and eliminates the sharp point, preventing injury to personnel and ensuring safety during use. The diameter of the largest part of the conical column ranges from 2 mm to 4 mm, and can be specifically set to a maximum diameter of 3 mm. The length of the conical column in the direction of its axis extension is 40 mm to 50 mm, and the length of the conical column can be specifically set to 45 mm. The size of the conical column 223 is adapted to the size of the connector housing and the connector, so as to facilitate insertion into the gap between the connector housing and the connector. This embodiment does not impose any specific limitations.

[0038] Specifically, such as Figure 3 As shown, the tapered post 223 is located in the engaging part 22, adjacent to the first end of the arc-shaped groove 221. The tangent of the tapered post 223 at the first end of the arc-shaped groove 221 is away from the arc-shaped groove 221. The axis of the tapered post 223 can be parallel to the tangent at the first end of the arc-shaped groove 221. This results in a relatively large angle between the tapered post 223 and the handle 21, facilitating operation when the operator holds the handle 21 to clean foreign objects from the connector housing. Alternatively, the tapered post 223 is located in the engaging part 22 adjacent to the second end of the arc-shaped groove 221, and the tangent of the tapered post 223 at the second end of the arc-shaped groove 221 is away from the arc-shaped groove 221. The axis of the tapered post 223 can be parallel to the tangent at the second end of the arc-shaped groove 221. The angle between the tapered post 223 and the handle 21 is relatively large, which makes it convenient for the operator to operate when cleaning foreign objects inside the connector housing by holding the handle 21.

[0039] Specifically, in the extension direction of the handle, the total length of the disassembly device can be set to 16 cm to 20 cm, preferably 18 cm.

[0040] In one possible implementation, such as Figure 3 As shown, a hanging hole 211 is provided at the other end of the handle 21, through which the disassembly device can be hung on the tool wall in the factory for easy storage and convenient access.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
