Description

Technical Field

[0001] This utility model relates to the field of paint surface measurement technology, specifically a Bluetooth-connected paint coating thickness measuring device. Background Technology

[0002] Coating thickness is generally measured using a coating thickness gauge. The coating thickness gauge can non-destructively measure the thickness of non-magnetic coatings on magnetic metal substrates and the thickness of non-conductive coatings on non-magnetic metal substrates. Coating thickness gauges have the characteristics of small measurement error, high reliability, good stability and easy operation.

[0003] However, existing coating thickness gauges require manual on / off operation during use, making them inconvenient for measuring paint surfaces. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given that the above-mentioned or existing technologies require manual on / off operation of the coating thickness gauge during use, making it inconvenient to use the coating thickness gauge for measuring paint surface.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A Bluetooth-connected paint coating thickness measuring device, characterized in that it includes:

[0008] The rebound mechanism includes a housing, a paint surface measurement module disposed inside the housing, and a probe monitoring component electrically fixed to one side of the paint surface measurement module.

[0009] The protective assembly includes a sleeve threaded to the outside of the housing, a support bracket fixed inside the sleeve, and an amplification assembly fixed to one end of the support bracket.

[0010] As a further improvement of this utility model: the outer shell has two external threaded grooves with a symmetrical structure, and a fluorescent sleeve is provided between the two external threaded grooves. A contact piece that can be electrically connected to the paint surface measurement module is embedded on one side of the fluorescent sleeve.

[0011] As a further embodiment of this utility model: a conductive post is electrically fixed to one side of the paint surface measuring module, and an extended conductive block is elastically connected inside the conductive post through an elastic element. The extended conductive block can abut and limit the contact plate.

[0012] As a further improvement of this utility model: a display module is embedded on one side of the paint surface measurement module. The display module is lower than the plane of the paint surface measurement module and can be electrically fixed to the probe monitoring component.

[0013] As a further embodiment of this utility model: the probe monitoring assembly includes a sliding column that is slidably located inside the housing. A thickness measuring probe is fixedly connected to one end of the sliding column. An induction coil is electrically fixedly connected to one side of the thickness measuring probe. The induction coil is fixedly connected in the groove of the sliding column, and a power supply coil is electrically contacted on one side of the induction coil. The power supply coil is fixed inside the housing and can abut against and limit the contact plate. The axis of the power supply coil and the axis of the support frame are on the same axis line.

[0014] As a further embodiment of this utility model: the support frame includes a spacer ring that can abut against and limit the sliding column, and two T-rods are fixedly connected to the outside of the spacer ring in a symmetrical structure. A collar is fixed between the two T-rods, and the collar is sleeved and installed with the amplification component through a sealing element.

[0015] As a further improvement of this invention: the magnifying component includes a convex lens, and the convex lens is coated with a protective film.

[0016] As a further improvement of this invention, the protective film is coated with a heat-insulating agent.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention allows the sleeve to be screwed off with an external threaded groove at one end. As the sleeve rotates outward, it can cause the support bracket to disengage from the elastic contact with the probe monitoring component. This allows the probe monitoring component, which has disengaged from the support bracket's contact limit, to extend elastically and make electrical contact with the paint surface measurement module, thereby enabling the device to start automatically and improving the efficiency of testing.

Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0031] Please see Figure 1-7 This is the first embodiment of the present invention, which provides a Bluetooth-connected paint coating thickness measuring device, comprising:

[0032] The rebound mechanism 100 includes a housing 101, a paint surface measurement module 102 disposed inside the housing 101, and a probe monitoring component 103 electrically fixed to one side of the paint surface measurement module 102.

[0033] The protective component 200 includes a sleeve 201 threaded to the outside of the housing 101, a support bracket 202 fixed inside the sleeve 201, and an amplification component 203 fixed to one end of the support bracket 202.

[0034] Specifically, the outer shell 101 has two external threaded grooves 101a with a symmetrical structure on the outside. A fluorescent sleeve 101b is provided between the two external threaded grooves 101a. A contact piece 101c that can be electrically connected to the paint surface measurement module 102 is embedded on one side of the fluorescent sleeve 101b.

[0035] Furthermore, after the sleeve 201 is screwed off with the external thread groove 101a at one end, as the sleeve 201 rotates outward, it can drive the support bracket 202 to disengage from the elastic contact with the probe monitoring component 103. This allows the probe monitoring component 103, which is disengaged from the contact limit of the support bracket 202, to extend elastically and make electrical contact with the paint surface measurement module 102, thereby realizing the automatic start-up of the device and improving the efficiency of detection and use.

[0036] Specifically, a conductive post 102a is electrically fixed to one side of the paint surface measurement module 102. An extended conductive block 102b is elastically connected inside the conductive post 102a through an elastic element. The extended conductive block 102b can abut and limit the contact with the contact piece 101c.

[0037] Furthermore, by extending the conductive block 102b to electrically connect with the conductive post 102a under the action of the elastic element, when the paint surface measurement module 102 is inserted into the housing 101, the conductive post 102a can be tightly abutted against the contact piece 101c, ensuring smooth circuit and avoiding poor connection.

[0038] Specifically, a display module 102c is embedded on one side of the paint surface measurement module 102. The display module 102c is lower than the plane of the paint surface measurement module 102 and can be electrically fixed to the probe monitoring component 103.

[0039] Furthermore, by making the display module 102c lower than the plane of the paint surface measurement module 102, it can be ensured that when the sleeve 201 is screwed onto the outer shell 101, the internal support 202 of the displaced sleeve 201 is less likely to rub against the display module 102c and cause accidental touches when using the display module 102c.

[0040] Specifically, the probe monitoring assembly 103 includes a sliding column 103a that is slidably limited inside the housing 101. One end of the sliding column 103a, which is fitted with an elastic element, is fixedly connected to a thickness measuring probe 103b. An induction coil 103c is electrically fixedly connected to one side of the thickness measuring probe 103b. The induction coil 103c is fixedly connected to the groove of the sliding column 103a, and a power supply coil 103d is electrically contacted on one side of the induction coil 103c. The power supply coil 103d is fixed inside the housing 101 and can abut against and limit the contact plate 101c. The axis of the power supply coil 103d is on the same axis as the axis of the support frame 202.

[0041] Furthermore, after the sleeve 201 is spirally separated from the outer shell 101, the slide column 103a, which is separated from the inner bracket 202 of the sleeve 201 and abuts against the limit, can be pushed to extend the limit of the slide column 103a retracted into the outer shell 101 by the support of the elastic element of compression reset. This allows the induction coil 103c installed in the slide column 103a to make electrical contact with the power supply coil 103d, restoring the overall power supply of the paint surface measuring device, realizing the automatic start of the device and improving work efficiency.

[0042] In summary, the Bluetooth-connected paint coating thickness measuring device uses a sleeve 201 to spirally separate from the outer shell 101, allowing the slide column 103a to be pushed and extended within the outer shell 101 by the elastic element supported by compression and reset. This causes the induction coil 103c installed inside the slide column 103a to make electrical contact with the power supply coil 103d, restoring the overall power supply to the paint coating measuring device, enabling automatic start-up of the device and improving work efficiency.

[0043] Please see Figure 8 and Figure 4 This is the second embodiment of the present invention, which provides an improved design for a Bluetooth-connected paint coating thickness measuring device.

[0044] Specifically, the support frame 202 includes a spacer ring 202a that can abut against and limit the sliding column 103a. The spacer ring 202a has two T-bars 202b fixedly connected to it in a symmetrical structure. A collar 202c is fixed between the two T-bars 202b. The collar 202c is fitted and installed with the amplification component 203 through a sealing element.

[0045] Furthermore, by using a spacer ring 202a that can abut against and limit the sliding column 103a, the sleeve 201 will not come into contact with or interfere with the thickness probe 103b after the sleeve 201 is threadedly connected to the outer shell 101 to the limit, thus ensuring the safety of the thickness probe 103b when it is sleeved inside the sleeve 201 for protection.

[0046] Specifically, the magnifying component 203 includes a convex lens 203a, and the convex lens 203a is coated with a protective film 203b.

[0047] Furthermore, the protective film 203b can protect the surface of the convex lens 203a from scratches, thereby improving the service life of the convex lens 203a.

[0048] Specifically, the protective film 203b is coated with a heat-insulating agent.

[0049] Furthermore, the heat-insulating agent coated on the outside of the protective film 203b can effectively maintain the service life of the protective film 203b without affecting the refractive function of the convex lens 203a.

[0050] When using this device to detect the thickness of the paint surface, the user screws off the sleeve 201 that is threaded onto the end of the probe monitoring component 103. As the sleeve 201 and the external thread groove 101a of the sleeve 201 are displaced and released, the probe monitoring component 103, which is elastically abutting against the support bracket 202 fixed inside the sleeve 201, elastically elongates and is exposed.

[0051] At this time, under the action of the bracket 202 in the sleeve 201, the sliding column 103a in the exposed probe monitoring component 103 can be pushed to extend the sliding column 103a that is retracted into the outer shell 101, supported by the elastic element that is compressed and reset. This allows the induction coil 103c installed in the sliding column 103a to make electrical contact with the power supply coil 103d, restoring the overall power supply of the paint surface measuring device and realizing the automatic start-up of the device.

[0052] When the display module 102c or the display environment is poor, the sleeve 201 is screwed to the external thread groove 101a of the outer housing 101, and the convex lens 203a inside the sleeve 201 can magnify it.

For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered.
