Figures 1 and 2 are the three-dimensional assembly and exploded schematic diagram of the detection device 1 of the present invention. As shown in Figures 1 and 2, the detection device 1 includes an actuating element 10, a positioning element 11, a driving component 1a, and an electronic component 1b. In this embodiment, the detection device 1 is used to detect the fixing strength of expansion screws. There are many types of expansion screws, and there are no special restrictions.

The actuator 10 is a rod body, such as a screw, which has a first end 10a and a second end 10b opposite to each other.

The positioning member 11 is arranged at the first end 10a of the actuating member 10, and has a first joint part 11a and a second joint part 11b, and the first joint part 11a is displaceably jointed relative to the actuating member 10. The actuator 10 and the second joint portion 11b are used to join a target test object 9 such as an expansion screw (as shown in FIG. 3).

In this embodiment, the positioning member 11 is a joint, such as a hexagonal nut. The first joint portion 11 a has a first opening 111, and the second joint portion 11 b has a second opening 112. For example, the first joining portion 11a and the second joining portion 11b are located on opposite sides (ie, upper and lower sides) of the positioning member 11.

Furthermore, the first opening 111 and the second opening 112 are in communication with each other. For example, the hole center of the first opening 111 and the hole center of the second opening 112 are located on the same axis L.

In addition, the first joint portion 11a is screwed to the actuator 10, and the second joint portion 11b is a screw connection structure. For example, the first opening 111 and the second opening 112 are screw holes.

In addition, according to the size of the actuator 10 and the target test object 9, the diameter of the first opening 111 can be the same as (not shown in the figure) or different from (as shown in Figure 3) the diameter of the second opening 112. Aperture.

The driving component 1a drives the actuator 10 to move linearly, and includes a bearing member 12 passing through the actuator 10, a driving member 13, a passive member 14 and a limiting member 15.

In this embodiment, the passive component 14 and the limiting component 15 are closely abutted (the two can be regarded as one body). The bearing member 12 is a thrust bearing, which is equipped with a plurality of annularly arranged balls 120, and the driving member 13 is arranged on the bearing member 12. When the driving member 13 is rotated, the driving member 10 is actuated to produce an upward linear movement At this time, the actuating member 10 can be caused to drive the positioning member 11 to produce displacement.

Furthermore, the bearing member 12 and the driving member 13 are arranged adjacent to each other between the first end 10a and the second end 10b of the actuating member 10. The bearing member 12 can be closer to the actuating member than the driving member 13 The first end 10a of the piece 10.

In addition, the active member 13, the passive member 14 and the limiting member 15 are all nut caps, which are screwed to the actuating member 10 to form a drawing screw assembly. For example, the passive element 14 and the limiting element 15 are arranged adjacent to the second end 10b of the actuating element 10, and the limiting element 15 is closer to the second end 10b.

The electronic component 1b is connected to the driving component 1a, and it includes a load cell 16 and a display 17 connected to the load cell 16 in communication (for example, through a wire 170 or wirelessly).

In this embodiment, the load cell 16 has a perforation 160 for the actuator 10 to pass through, so that the load cell 16 measures the operating force of the actuator 10 and displays the operating force value on the display 17 . For example, the bearing element 12 is arranged on the load element 16 to reduce the friction force applied to the load element 16 and facilitate the rotation of the driving element 13.

Furthermore, the supporting member 18 is a screw bolt group to screw the load element 16. For example, the load element 16 has a through hole 160 through which the actuating member 10 can pass and a screw hole 161 located on the left and right of the through hole 160, so that the screw hole 161 is screwed to the screw 18a of the support member 18, and The bolt head 18b of the supporting member 18 is used as a base to support the load element 16.

In addition, the bottom surface of the bolt head 18b of the supporting member 18 and the environmental surface S of the floor (as shown in Figure 3) are on the same plane, and the bottom surface of the second joint 11b of the positioning member 11 is set on a On the fixed seat 30 (as shown in FIG. 3) fixed by the target test object 9, the target test object 9 fixes the fixed seat 30 below the environmental surface S. In this embodiment, an expansion screw is used as the target test object 9, which is fixed in the cement under the surface S of the environment.

The detection device 1 tests the pulling force of the target test object 9 fixed below an environmental surface S (such as a product structure surface, a wall, a floor, or a ceiling, etc.). This embodiment mainly tests the pull-out force of the expansion screw used in the fixing seat 30 of a raised floor to fix on the floor, that is, the pull-out force of the expansion screw to loosen the cement floor.

When using the detection device 1, as shown in Figure 3, the driving assembly 1a is first installed on the actuating member 10, and then the actuating member 10 is passed through the load cell 16 to screw the positioning member 11 In the first joining portion 11a, the actuating member 10 is a rod body. Then, one end of the supporting members 18 is screwed to the screw holes 161 on the left and right of the load element 16, and then one end of the positioning member 11 is fixed to the target test object 9, and the positioning member 11 is It is set on the fixed seat 30 fixed to the target test object 9, and one end surface of the support 18 is erected on the environmental surface S. Afterwards, rotate (in the direction of rotation R as shown in Figure 1) the driving member 13. Since most of the bolts are right-handed threads, the driving member 13 rotates clockwise, so that the actuator 10 can only perform linear displacement movement. (As shown in the upward direction Z in Figures 1 and 3), at this time, the actuating member 10 will generate an upward force on the positioning member 11 to generate an upward pulling force on the target test object 9, and the load The element 16 measures the upward working force, and displays the value of the upward working force on the display 17.

Therefore, if the display 17 shows the test value and the specified pulling force has been reached, the test is stopped, that is, the target test object 9 has not moved upward (or the positioning member 11 has not left the environment where the fixing seat 30 is located. Surface S), it means that the fixed strength of the target test object 9 fixed on the environmental surface S meets the requirements; on the contrary, if the display 17 shows the test value and the specified pull-out force is not reached, it is the target test object 9 has moved upward (or the positioning member 11 has left the environmental surface S where the fixing seat 30 is located), and the expansion screw (the target test object 9) has been loosened, which means that the target test object 9 is fixed on the environmental surface S The fixing strength does not meet the requirements. For example, the required pull-out force is related to the size of the target test object 9. For example, the pull-out force of the M6 bolt (target test object 9) must be 800 kg or more, and the M12 bolt (target test object 9) The pulling force must be more than 2000 kg.

In summary, the detection device 1 of the present invention can easily detect the fixing strength of the expansion screw through the cooperation of the actuating member 10 and the positioning member 11, which is beneficial to know the reliability of the product using the expansion screw. degree.
