Description

Technical Field

[0001] This utility model relates to the field of measuring instruments, specifically to a thermometer fixing clip. Background Technology

[0002] A thermometer is an instrument used to measure temperature and is widely used in various fields, such as scientific experiments, industrial production, and daily life. Due to their different structures and functions, there are many types of thermometers, such as semiconductor thermometers and thermocouple thermometers. The accuracy of a thermometer directly affects the quality of experimental results and production processes.

[0003] Current thermometer mounting brackets consist of only a single clamp, with a very simple structure. When in use, this clamp holds the thermometer and the bracket together. However, the clamping force is insufficient, often resulting in the thermometer becoming loose, tilted, or falling off, which is detrimental to measurement or calibration. This can lead to inaccurate results and waste the operator's time and effort. Utility Model Content

[0004] The purpose of this utility model is to provide a thermometer fixing clip to solve the problem of insufficient clamping force when fixing the thermometer in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A thermometer fixing clip includes a fixing device, an extension rod mounted on the fixing device, and a clamping assembly fixedly mounted on the extension rod at one end away from the fixing device. The clamping assembly is provided in at least one set, and each set of clamping assemblies includes two elastic clips. The elastic clips are symmetrically installed, and each elastic clip is provided with a groove. The grooves of the two symmetrically installed elastic clips form a clamping opening, which is used to fix the thermometer.

[0007] In the above technical solution, the user installs the fixing device of the device on an external fixing body, and the fixing device can be fixed to the external fixing body. Then, the user places the thermometer in the clamp, and the symmetrically installed elastic clips will deform, generating a clamping force to tighten the thermometer, thereby fixing the thermometer at the clamp and preventing loosening. Since the elastic clips are fixedly connected to the extension rod, and the extension rod is installed on the fixing device, the entire device can remain fixed, and the thermometer can also remain relatively fixed.

[0008] Preferably, the inner surfaces of the elastic clips are in contact with each other. When the thermometer is installed in the clamp, compared to the state where the elastic clips are not in contact, the elastic clips with their inner surfaces in contact are stretched at a larger angle by the thermometer, resulting in greater deformation. This allows the elastic clips to exert a greater clamping force on the thermometer, resulting in better stability.

[0009] Preferably, the end of the extension rod away from the fixing device is provided with a mounting groove, and the elastic clip and the extension rod are fixed in the mounting groove by a fixing member. Under the action of the fixing member, the elastic clip fits more tightly, and at the same time, the elastic clip and the extension rod are firmly fixed, resulting in better stability.

[0010] Preferably, it also includes an adjustment device located between the clamp and the fixing member. The adjustment device is used to adjust the clamping force between the elastic clips, for example, by adjusting the tightness between the two elastic clips, or by adjusting the distance between the deformation fulcrum of the elastic clip and the clamp, thereby better fixing the thermometer and improving adjustability.

[0011] Preferably, the adjusting device includes an adjusting bolt and an adjusting nut, which are threadedly connected; the adjusting bolt passes through and connects two elastic clips. The adjusting bolt brings the deformation fulcrum of the elastic clips closer to the clamping jaws, increasing the clamping force and improving stability. In use, the user adjusts the adjusting nut according to the size of the thermometer, thereby changing the clamping force of the elastic clips. Different sizes of thermometers require different clamping forces, providing greater adaptability.

[0012] Preferably, the groove of the elastic clip is a V-shaped groove. The thermometer and the elastic clip have line contact. Compared with the arc-shaped clip, the clamping opening formed by the V-shaped groove has more contact positions with the thermometer. When thermometers of different diameters are installed in the clamping opening, there are always four contact positions with the clamping opening, which can be used for thermometers of more diameters. At the same time, the force points of the thermometer in the clamping opening are more dispersed, reducing the risk of the thermometer's outer wall breaking due to excessive clamping force, thus improving applicability and safety.

[0013] Preferably, the end of the elastic clip away from the fixing device is provided with a bent portion, and the bent portions of the two elastic clips form a guide opening. When installing the thermometer, it is inserted through the guide opening. Because the guide opening has a certain angle, when installing the thermometer, inserting the thermometer through the guide opening will cause the thermometer to spread open the two elastic clips, widening the clamping opening and clamping the thermometer, avoiding the need for the user to manually pry open the elastic clips, thus improving convenience.

[0014] Preferably, an anti-slip pad is provided on the inner side of the clamp. This increases the friction between the thermometer and the clamp, improves the fixing effect, and reduces wear caused by direct contact between the outer surface of the thermometer and the clamp, resulting in better stability and protection.

[0015] Preferably, the fixing device includes a sleeve, a fixing rod, and a first fixing bolt. The fixing rod is mounted on the outer surface of the sleeve; the first fixing bolt is threadedly connected to the sleeve and extends into the inner cavity of the sleeve. In use, an external fixing object passes through the sleeve. When adjusted to a suitable position, the first fixing bolt can be turned, which will press the external fixing object against the inner wall of the sleeve, generating a clamping force on the external fixing object, thereby fixing the fixing device to the external fixing object. This provides higher adjustability and better stability.

[0016] Preferably, the end of the fixed rod away from the jacket is provided with a sliding cavity. The extension rod is installed on the sliding cavity and slidably connected to the fixed rod. The second fixing bolt is threaded to the fixed rod and can extend into the sliding cavity to fix the extension rod. The extension rod is longer than the fixed rod, and the surface of the extension rod that contacts the second fixing bolt is flat. In use, the length of the extension rod extending out of the fixed rod is adjusted according to actual needs. When it reaches a suitable position, the second fixing bolt is turned, and the second bolt will press the extension rod into the sliding cavity, generating a clamping force on the extension rod, thereby fixing the extension rod on the sliding cavity of the fixed rod. This provides higher adjustability and better stability. The flat surface of the contact surface between the extension rod and the second fixing bolt improves the stabilizing effect of the second fixing bolt on the extension rod. At the same time, the flat surface on the extension rod prevents the extension rod from rotating axially relative to the sliding cavity, resulting in better stability.

[0017] The beneficial effects of this utility model are:

[0018] The fixing device and extension rod allow the entire device to be fixed to an external fixed object. The elastic clips deform when the thermometer is installed in the clamp, creating a clamping force to hold the thermometer firmly in the clamp. This avoids situations where the thermometer loosens, tilts, or falls due to insufficient clamping force, which is detrimental to measurement or calibration. It reduces measurement errors and saves time and effort for operators. At the same time, the elastic clips can also clamp thermometers of different sizes, improving applicability.

[0023] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0024] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0025] Example 1:

[0026] like Figure 1-2 An embodiment 1 of a thermometer fixing clip shown includes a fixing device 1 and an extension rod 2 mounted on the fixing device 1. The fixing device 1 includes a sleeve 101, a fixing rod 102, and a first fixing bolt 103. The fixing rod 102 is mounted on the outer surface of the sleeve 101. The first fixing bolt 103 is threadedly connected to the sleeve 101 and can extend into the inner cavity of the sleeve 101. A sliding cavity is provided at the end of the fixing rod 102 away from the sleeve 101. The extension rod 2 is mounted on the sliding cavity and slidably connected to the fixing rod 102. The second fixing bolt 203 is connected to the fixing rod 102. The fixed rod 102 is threaded and extends into the sliding cavity to fix the extension rod 2. The extension rod 2 is longer than the fixed rod 102. The side of the extension rod 2 that contacts the second fixing bolt 201 is flat. The system also includes a clamping assembly fixedly mounted on the extension rod 2 at the end away from the fixing device 1. At least one set of clamping assemblies is provided. Each set of clamping assemblies includes two elastic clips 4, which are symmetrically installed. Each elastic clip 4 has a groove 401. The grooves 401 of the two symmetrically installed elastic clips 4 form a clamping opening 402 for fixing the thermometer. The inner surfaces of the elastic clips 4 are in contact with each other. The end of the extension rod 2 away from the fixing device 1 has a mounting groove. The elastic clips 4 and the extension rod 2 are fixed in the mounting groove by a fastener 3.

[0027] Specifically, the sleeve 101 is a hollow cylinder extending from top to bottom. When the user uses it, they first slip the sleeve 101 onto the outer rod-shaped object, initially adjusting the sleeve 101 to the desired height. Holding the device with one hand, the user tightens the first fixing bolt 103 with the other. The first fixing bolt 103 presses the outer rod against the inner wall of the sleeve 101, generating a clamping force on the outer rod-shaped object, thus fixing the sleeve 101 to the outer rod-shaped object. The fixing rod 102 can be a long strip with rounded corners. The fixing rod 102 has a sliding cavity inside, with a sliding cavity opening at one end away from the sleeve 101. The other end of the fixing rod 102 is welded to the outer surface of the sleeve 101. The fixing rod 102 can also be integrally formed with the sleeve 101 or threadedly connected, improving strength and stability. The axis of the fixing rod 102 is perpendicular to the axis of the sleeve 101, which is more in line with the conventional thermometer usage orientation. The shape of the sliding connection between the extension rod 2 and the fixed rod 102 matches the shape of the sliding cavity. The contact surface between the extension rod 2 and the second fixing bolt 201 is flat, which improves the fixing effect of the second fixing bolt 201 on the extension rod 2. At the same time, the flat surface on the extension rod 2 prevents the extension rod 2 from rotating axially relative to the sliding cavity, resulting in better stability. The user can pull the extension rod 2, which will slide within the sliding cavity. After initially pulling the extension rod 2 to a suitable length, tightening the second fixing bolt 201 will press the extension rod 2 into the sliding cavity, generating a clamping force and thus fixing the extension rod 2 in the sliding cavity of the fixed rod 102. The fastener 3 installed on the extension rod 2 consists of two parallel rivets, which fix the elastic clip 4, whose inner surface is tightly fitted, to the mounting groove at the end of the extension rod 2 away from the clip 101. This not only fixes the elastic clip 4 to the extension rod 2 but also ensures the axial stability of the elastic clip 4, preventing the thermometer from tilting. During thermometer installation, the user places the thermometer in the clamp 402. The symmetrically installed elastic clips 4 deform, generating a clamping force to hold the thermometer in place at the clamp 402, preventing loosening. Therefore, the entire device remains fixed, and the thermometer remains relatively stable. Simultaneously, the elastic clips 4, under the action of the fixing element 3, can fit more tightly, resulting in greater deformation and providing a stronger clamping force.

[0028] The beneficial effects of this embodiment are as follows: The fixing device 1 and the extension rod 2 can fix the entire device to an external fixed object. The elastic clamp 4 deforms when the thermometer is installed in the clamp 402, generating clamping force to firmly hold the thermometer in the clamp 402. This avoids situations where the thermometer loosens, tilts, or falls due to insufficient clamping force, which is detrimental to measurement or calibration, reducing measurement errors and saving operators' time and effort. The elastic clamp 4 can also hold thermometers of different sizes, improving applicability. The design of the sliding cavity on the extension rod 2 and the design of the clamp 101 enable the thermometer to be fixed in different positions, improving adjustability.

[0029] Example 2:

[0030] A second embodiment of a thermometer clamp differs from the first embodiment in that it further includes an adjusting device 5. The adjusting device is located between the clamping opening 402 and the fixing member 3. The adjusting device is used to adjust the clamping force between the elastic clamping pieces 4. The adjusting device 5 includes an adjusting bolt 501 and an adjusting nut 502, which are threaded together. The adjusting bolt 501 passes through and connects the two elastic clamping pieces 4. When using this device, the user should loosen the adjusting nut 502 appropriately before installing the thermometer, adjusting the degree of loosening according to the size of the thermometer to facilitate insertion. After the thermometer is inserted into the clamping opening 402, the adjusting nut 502 is tightened to increase the clamping force, resulting in better stability and greater adaptability.

[0031] In addition, another implementation of the adjustment device 5 is provided, such as Figure 3 As shown, the difference from the above embodiment is that an adjustment groove 503 is provided between the clamping opening 402 of the elastic clamp 4 and the fixing member 3. The screw portion of the adjusting bolt 501 passes through the adjustment groove 503. The width of the adjustment groove 503 is smaller than the diameter of the nut of the adjusting bolt 501 and the adjusting nut 502. The direction of movement of the adjusting bolt 501 in the adjustment groove 503 is consistent with the direction of movement of the extension rod 2 in the sliding cavity of the fixing rod 102. When using this device, the user can change the position of the deformation fulcrum of the elastic clamp 4 by changing the position of the adjusting bolt 501 in the adjustment groove 503, thereby changing the degree of deformation of the elastic clamp 4 and adjusting the clamping force. The closer the adjusting bolt 501 is to the clamping opening 402, the greater the deformation of the elastic clamp 4 when a thermometer of the same size is installed in the clamping opening 402, and the greater the clamping force. The farther the adjusting bolt 501 is from the clamping opening 402, the smaller the deformation of the elastic clamp 4, and the smaller the clamping force.

[0032] Example 3:

[0033] Embodiment 3 of a thermometer fixing clip differs from Embodiment 1 or Embodiment 2 in that the groove 401 of the elastic clip 4 is a V-shaped groove, the grooves 401 of the two elastic clips 4 are symmetrical, the preferred angle range of the V-shaped groove is 100°-150°, and in this embodiment, the included angle of the V-shaped groove is 120°. In addition, those skilled in the art can also make adaptive adjustments to the included angle of the V-shaped groove according to the size of the thermometer. A bending portion 403 is provided at the end of the elastic clip 4 away from the fixing device 1, and the bending portions 403 of the two elastic clips 4 form a guide opening. The preferred angle range of the guide opening is 90°-120°, and in this embodiment, the angle of the guide opening is preferably 90°. In addition, those skilled in the art can also make adaptive adjustments to the angle of the guide opening according to the size of the thermometer. An anti-slip pad is provided on the inner side of the clamp 402.

[0034] Specifically, when using the device, the thermometer probe faces downwards, and the outer wall of the thermometer is directly inserted into the clamp 402 through the guide port. This avoids the user having to manually pry open the elastic clips 4. Because the guide port has a certain angle, when installing the thermometer, inserting it through the guide port will cause the thermometer to spread open the two elastic clips, widening the clamp and tightening the thermometer, making installation easier. The clamp 402, formed by the V-groove, has more contact points with the thermometer. When thermometers of different diameters are installed in the clamp, there are always four contact points with the clamp, making it suitable for thermometers of different diameters. At the same time, the force on the thermometer is more distributed in the clamp 402, reducing the risk of the thermometer's outer wall breaking due to excessive clamping force. This improves applicability and safety. The raised design increases the contact area between the elastic clips 4 and the thermometer, improving the fixing effect and stability. The anti-slip pad on the inner side of the clamp 402 increases the friction between the thermometer and the clamp 402, improving the fixing effect. At the same time, it reduces the wear caused by direct contact between the outer surface of the thermometer and the clamp 402, resulting in better stability and protection.

[0035] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
