[0044] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0045] In order to solve the problems described in the related art, an embodiment of the present application provides a handheld thickness measuring device, which includes a rod-shaped body, an adapter and a detection device. The detection device is provided on the adapter to be connected to the rod-shaped body through the adapter. The locking bolt of the adapter has a first preset state and a second preset state. When the locking bolt is in the first preset state, the first matching structure and the second matching structure of the adapter are matched to lock the first bracket and the second bracket. When the locking bolt is in the second preset state, the first matching structure and the second matching structure are separated to form a preset spacing, so that the first bracket and the second bracket are unlocked. In the present disclosure, by providing an adapter to connect the detection device and the rod-shaped body, it is convenient to realize the detection of various structures without changing the holding method; and the adapter controls the matching structure on the first bracket and the second bracket to form or release the matching through the locking bolt. The matching strength of the matching structure is high, which can prevent the adapter from colliding with the external structure and causing the shape of the adapter to change, which is conducive to improving the user experience.

[0046] According to an exemplary embodiment of the present application, Figure 1 As shown, this embodiment provides a handheld thickness measuring device. After the economizer has been working for a long time, its inner wall will become thinner due to corrosion. The staff can hold the handheld thickness measuring device and insert the handheld thickness measuring device into the designated position of the economizer to detect the thickness of the designated position. The handheld device has the advantages of being easy to carry and accurate in measuring position.

[0047] like Figure 1 As shown, the handheld thickness measuring device includes a rod-shaped body 10, which can be hollow or solid. The length of the rod-shaped body 10 can be any value, and the embodiment of the present disclosure does not impose any restrictions on the length of the rod-shaped body 10. In some optional embodiments, the rod-shaped body 10 can also be configured as a retractable structure, so that the length can be arbitrarily adjusted during use to provide an optimal user experience.

[0048] like Figure 1 As shown, the handheld thickness measuring device further includes an adapter 20 and a detection device 30 . The adapter 20 is disposed at one end of the rod-shaped body 10 . The detection device 30 is connected to the rod-shaped body 10 through the adapter 20 . The adapter 20 is used to install the detection device 30 .

[0049] Wherein, when the holding method remains unchanged, the adapter 20 can also enable the detection device 30 to have different angles to adapt to economizers of different shapes, for example, to detect curved pipes of economizers.

[0050] like Figure 2 and Figure 3 As shown, the adapter 20 includes a first bracket 21 and a second bracket 22. The first bracket 21 and the second bracket 22 are rotatably connected around a first preset rotation axis. The first bracket 21 is connected to the rod-shaped body 10, and the second bracket 22 is connected to the detection device 30. That is, by rotating the first bracket 21 and the second bracket 22, the positional relationship between the detection device 30 and the rod-shaped body 10 can be adjusted, thereby adjusting the detection direction.

[0051] See Figure 2 and Figure 3 A first matching structure 211 is provided on the first bracket 21, and a second matching structure 221 is provided on the second bracket 22. When the first matching structure 211 and the second matching structure 221 are matched, the first bracket 21 and the second bracket 22 are fixedly connected. When the first matching structure 211 and the second matching structure 221 are released from matching, the first bracket 21 and the second bracket 22 can be rotated arbitrarily around the first preset rotation axis, and even the first bracket 21 and the second bracket 22 can be disassembled and separated into two independent brackets.

[0052] See Figure 2 and Figure 3 The adapter 20 further includes a locking bolt 23. When the locking bolt 23 is in a first preset state, the first mating structure 211 can mate with the second mating structure 221 to lock the rotation angle of the first bracket 21 and the second bracket 22. When the locking bolt 23 is in a second preset state, the first mating structure 211 and the second mating structure 221 separate to unlock the first bracket 21 and the second bracket 22.

[0053] It should be noted that the locking bolt 23 can be switched between the first preset state and the second preset state by rotating the locking bolt 23. For example, by rotating the locking bolt 23 clockwise a certain number of times, the locking bolt 23 enters the first preset state. Correspondingly, by rotating the locking bolt 23 counterclockwise a certain number of times, the locking bolt 23 enters the second preset state.

[0054] In the embodiments of the present disclosure, by providing an adapter to connect the detection device and the rod-shaped main body, it is beneficial to detect various structures without changing the holding manner. Moreover, the adapter controls the mating structures on the first bracket and the second bracket to form a fit or release the fit through a locking bolt. The mating strength of the mating structures is high, which can prevent the adapter from hitting an external structure and causing a change in the shape of the adapter, thus enhancing the user experience.

[0055] In one exemplary embodiment, as Figure 1 and Figure 2 shown, this embodiment provides a handheld thickness measuring device. The handheld thickness measuring device includes a rod-shaped main body, an adapter, and a detection device. The detection device is arranged on the adapter to be connected to the rod-shaped main body through the adapter. The locking bolt of the adapter has a first preset state and a second preset state. When the locking bolt is in the first preset state, the first mating structure and the second mating structure of the adapter form a fit to lock the first bracket and the second bracket. When the locking bolt is in the second preset state, the first mating structure and the second mating structure are separated to form a preset distance, so that the first bracket and the second bracket are unlocked.

[0056] In some embodiments, as Figure 2 and Figure 3 shown, one of the first mating structure 211 and the second mating structure 221 is a plurality of protrusions, and the other is a plurality of grooves. The plurality of protrusions and the plurality of grooves are opposite to each other and are both arranged at intervals along the circumferential direction of the first preset rotation axis. Refer to Figure 3 , for example, the first mating structure 211 is a plurality of protrusions, and the second mating structure 221 is a plurality of grooves. When the locking bolt 23 is in the first preset state, the plurality of protrusions extend into the plurality of grooves, and the protrusions and the grooves form an interference fit, which can ensure that the protrusions can enter or exit from the grooves, and can also prevent the protrusions and the grooves from generating relative movement in the circumferential direction of the first preset rotation axis, thereby preventing the first bracket 21 and the second bracket 22 from rotating relative to each other.

[0057] In this embodiment, the shapes of each protrusion and each groove are not limited. The protrusion can be a fan-shaped convex block, a cylinder, a cuboid, etc.

[0058] In other embodiments, the opposing surfaces of the first mating structure 211 and the second mating structure 221 are frosted surfaces. It is understood that the locking bolt 23 can provide a force acting on the first mating structure 211 and the second mating structure 221 in the axial direction of the locking bolt 23. For example, when the locking bolt 23 is in the first preset state, an abutment force is formed between the first mating structure 211 and the second mating structure 221. Therefore, the opposing surfaces of the first mating structure 211 and the second mating structure 221 can be set as frosted surfaces to increase the friction between the first mating structure 211 and the second mating structure 221, thereby preventing the first mating structure 211 and the second mating structure 221 from moving relative to each other in the circumferential direction of the first preset rotation axis.

[0059] Among them, such as Figure 3 As shown, the first bracket 21 includes a mounting seat 21a and a mounting frame 21b. One side of the mounting seat 21a is connected to the rod-shaped body 10, and the other side of the mounting seat 21a is connected to the mounting frame 21b. Figure 3 A first preset through hole is provided on the mounting frame 21b, and a second preset through hole is provided on the second bracket 22. The axial directions of the first preset through hole and the second preset through hole coincide with the first preset rotating shaft, and at least part of the structure of the locking bolt 23 is located in the first preset through hole and the second preset rotating shaft.

[0060] Among them, such as Figure 3 As shown, two mounting brackets 21b are provided. The mounting base 21a and the two mounting brackets 21b are arranged in a U-shape to define a U-shaped cavity. At least part of the structure of the detection device 30 is located within the U-shaped cavity. In this embodiment, the provision of two mounting brackets 21b helps to reduce the length of the adapter 20, thereby reducing or preventing the adapter 20 from colliding with external structures.

[0061] Among them, such as Figure 3 As shown, the locking bolt 23 includes a bolt shank 231 , and the bolt shank 231 is threadedly engaged with one of the first preset through hole and the second preset through hole, and is clearance-engaged with the other one.

[0062] For example, see Figure 3 The locking bolt 23 also includes a bolt head 232, which is located on the side of the second bracket 22 away from the mounting frame 21b. The bolt rod 231 is threadedly matched with the first preset through hole and has a clearance fit with the second preset through hole. By rotating the locking bolt 23, the bolt head 232 can be made close to and squeeze the second bracket 22, so that the second bracket 22 is matched and locked with the mounting frame 21b.

[0063] In some optional embodiments (not shown in the accompanying drawings), the shank of the locking bolt is rotatably connected to the first predetermined through-hole and threadably engaged with the second predetermined through-hole. This rotatable connection means that the shank can only rotate relative to the first predetermined through-hole and cannot move relative to the axial direction. Therefore, when the locking bolt is rotated, the locking bolt can drive the second bracket toward or away from the mounting bracket of the first bracket, thereby switching between a locked state and a disengaged state.

[0064] Among them, such as Figure 2 and Figure 3 As shown, the preset position of the first bracket 21 has a preset mark 212, and the preset mark 212 is such as an arrow pattern engraved or plated on the first bracket 21. The present disclosure does not limit the preset position too much, and any position near the first matching structure 211 can be used as the preset position. Figure 2 and Figure 3 The second bracket 22 is provided with a plurality of angle scales 222, which are arranged along the circumference of the first predetermined rotation axis. It is understood that when the second bracket 22 and the first bracket 21 are rotated, different angles on the second bracket 22 may align with the predetermined mark 212, thereby determining the relative position of the second bracket 22 and the first bracket 21.

[0065] Among them, such as Figure 2 and Figure 3 As shown, the rod-shaped body 10 includes a first rod body 11 and a second rod body 12. A control unit 40 is provided between the first rod body 11 and the second rod body 12. The first rod body 11 is provided with an adapter 20 on the side away from the control unit 40. The control unit 40 may include a switch, a display screen, a communication module, and a power supply.

[0066] Among them, such as Figure 1 As shown, the first rod body 11 is a cylindrical structure and defines an accommodating cavity. The detection device 30 is electrically connected to the control unit 40 through a signal line, and the signal line passes through the accommodating cavity.

[0067] Among them, such as Figures 1 to 3 As shown, the detection device 30 includes a thickness sensor 31, which is rotatably connected to the second bracket 22 about a second predetermined rotation axis. The detection device 30 also includes a visual sensor 32, which is rotatably connected to the second bracket 22 about a third predetermined rotation axis. The second predetermined rotation axis and the third predetermined rotation axis are both parallel to the first predetermined rotation axis.

[0068] Among them, fasteners 24 (such as bolts) are provided at the second preset rotating shaft and the third preset rotating shaft. By rotating the bolts, the thickness sensor 31 and the visual sensor 32 can be locked so that the thickness sensor 31 and the visual sensor 32 have a specific detection angle.

[0069] Other embodiments of the present application will be readily contemplated by those skilled in the art upon consideration of the specification and practice of the disclosure herein. The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include known common general knowledge or conventional technical means in the technical field not disclosed in the present application.
