[0001] The utility model relates to the technical field of lighter measurement, in particular to a lighter measurement fixture. Background Art

[0002] Before leaving the factory, lighters need to be subjected to product tests, in which the appearance dimensions of the lighters are measured to ensure the dimensional consistency of the lighters. Among them, the dimensions of the lighter itself and the line widths on the surface patterns of the lighters need to be measured. Therefore, when measuring the dimensions of the lighter, the lighter needs to be placed in different states to measure the elements at the required positions on the lighter.

[0003] When measuring a lighter, it is necessary to position and clamp the lighter accordingly. Therefore, corresponding fixtures are required to position or clamp the lighter. Currently, corresponding fixtures need to be configured for the lighter in different placement states. For example, when the top surface of the lighter is facing up, it is necessary to use corresponding positioning and clamping of the bottom surface of the lighter to expose the top surface of the lighter for measurement; when the front surface of the lighter is facing up, it is necessary to use corresponding positioning and clamping of the back surface of the lighter to expose the front surface of the lighter for measurement. Therefore, corresponding fixtures need to be configured for lighters in different placement states, resulting in poor versatility of the fixtures and increased fixture costs. Summary of the Utility Model

[0025] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part rather than all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 1 to 5 As shown, the lighter measuring fixture of the present utility model includes a measuring base 1, a first positioning member 2 and a second positioning member 3. The first positioning member 2 and / or the second positioning member 3 are slidably arranged on the measuring base 1. On one side of the first positioning member 2 close to the second positioning member 3, a first positioning surface 4 is arranged. On one side of the second positioning member 3 close to the first positioning member 2, a second positioning surface 5 is arranged. The first positioning surface 4 and the second positioning surface 5 are relatively close to or away from each other. A third positioning surface 6 is arranged on the base. A variable positioning groove 7 is formed among the first positioning surface 4, the second positioning surface 5 and the third positioning surface 6.

[0027] The lighter measuring fixture of the present application positions different surfaces of the lighter through the variable positioning groove 7 to improve the versatility of the lighter testing fixture. Specifically, it includes a measuring base 1, a first positioning member 2 and a second positioning member 3. The first positioning member 2 and / or the second positioning member 3 are slidably arranged on the measuring base 1. Preferably, both the first positioning member 2 and the second positioning member 3 of the present application are slidably arranged on the measuring base 1 to realize the relative approach or separation of the first positioning member 2 and the second positioning member 3. Further, at one end of the first positioning member 2 close to the second positioning member 3, a first positioning surface 4 is arranged. At one end of the second positioning member 3 close to the first positioning member 2, a second positioning surface 5 is arranged. Since the first positioning member 2 and the second positioning member 3 are oppositely arranged, the first positioning surface 4 and the second positioning surface 5 are oppositely arranged. In addition, a third positioning surface 6 is arranged on the measuring base 1. Therefore, a variable positioning groove 7 is formed among the first positioning surface 4, the second positioning surface 5 and the third positioning surface 6, and it is a rectangular groove. Since the lighter is rectangular, the rectangular groove is convenient for clamping and positioning the lighter. Since the first positioning surface 4 and the second positioning surface 5 can be relatively close to or away from each other, the groove width of the variable positioning groove 7 can be adjusted, so that the variable positioning groove 7 can clamp and position the lighter in the width direction, height direction and thickness direction, realizing the clamping and positioning of the lighter in three dimensions. Then, through corresponding measuring mechanisms (such as measuring projectors and other measuring mechanisms), any side of the lighter can be measured, which not only improves the versatility of the lighter, but also improves the measuring efficiency.

[0028] In one embodiment, a sliding groove 8 is provided on the measuring base 1, a sliding block 9 is provided on the first positioning member 2, and the sliding block 9 is slidably arranged in the sliding groove 8.

[0029] As Figure 1 , Figure 2 and Figure 3 shown, the first positioning member 2 needs to move on the measuring base 1 to achieve the adjustment function of the variable positioning groove 7. Specifically, a sliding groove 8 is provided on the measuring base 1, a sliding block 9 is provided on the first positioning member 2, and the sliding block 9 is slidably arranged in the sliding groove 8. Therefore, the cooperation between the sliding block 9 and the sliding groove 8 can realize the relative sliding of the first positioning member 2 on the measuring base 1.

[0030] In one embodiment, the sliding direction of the first positioning member 2 on the measuring base 1 is the first direction, a positioning block 10 is provided on the measuring base 1, a sliding rod 11 is provided on the positioning block 10, the sliding rod 11 is along the first direction, and the first positioning member 2 and the second positioning member 3 are sleeved on the sliding rod 11.

[0031] As Figure 1 , Figure 2 and Figure 3 shown, the second positioning member 3 needs to move on the measuring base 1 to achieve the adjustment function of the variable positioning groove 7. Specifically, the sliding direction of the first positioning member 2 on the measuring base 1 is the first direction, a positioning block 10 is provided on the measuring base 1, the positioning block 10 is fixedly connected to the measuring base 1, or the positioning block 10 is integrally formed with the measuring base 1. Preferably, the positioning block 10 is integrally formed with the measuring base 1. Further, a sliding rod 11 is provided on the positioning block 10, the axial direction of the sliding rod 11 is along the first direction, both the first positioning member 2 and the second positioning member 3 are sleeved on the sliding rod 11, and the second positioning member 3 being sleeved on the sliding rod 11 can realize the sliding of the second positioning member 3 relative to the measuring base 1 on the sliding rod 11. Since the first positioning member 2 realizes the sliding relative to the measuring base 1 through the cooperation between the sliding block 9 and the sliding groove 8, the first positioning member 2 being sleeved on the sliding rod 11 can further improve the sliding stability of the first positioning member 2 on the measuring base 1.

[0032] In one embodiment, the sliding rod 11 includes a first sliding rod 12 and a second sliding rod 13 arranged in parallel, first sliding holes 14 and second sliding holes 15 are provided on both the first positioning member 2 and the second positioning member 3, the first sliding holes 14 on the first positioning member 2 and the second positioning member 3 are sleeved on the first sliding rod 12, and the second sliding holes 15 on the first positioning member 2 and the second positioning member 3 are sleeved on the second sliding rod 13.

[0033] AsFigure 1 , Figure 2 and Figure 3 As shown in Figure 2 , Figure 3 , the sliding rod 11 includes a first sliding rod 12 and a second sliding rod 13. The first positioning member 2 and the second positioning member 3 are inserted through the corresponding sliding rod 11 to further improve the sliding stability. Specifically, the first sliding holes 14 and the second sliding holes 15 are provided on both the first positioning member 2 and the second positioning member 3. The first sliding holes 14 on the first positioning member 2 and the second positioning member 3 are simultaneously inserted through the first sliding rod 12, and the second sliding holes 15 on the first positioning member 2 and the second positioning member 3 are simultaneously inserted through the second sliding rod 13. The diameters of the first sliding rod 12 and the second sliding rod 13 are the same, and the diameters of the first sliding holes 14 and the second sliding holes 15 are the same. It is only necessary that the diameters of the first sliding holes 14 and the second sliding holes 15 are slightly larger than the diameters of the first sliding rod 12 and the second sliding rod 13, which can not only realize the relative sliding of the first positioning member 2 and the second positioning member 3 on the first sliding rod 12 and the second sliding rod 13, but also prevent the first sliding rod 12 and the second sliding rod 13 from moving around in the first sliding holes 14 and the second sliding holes 15.

[0034] In one of the embodiments, a compression spring 16 is further included. The first positioning member 2, the second positioning member 3, and the positioning block 10 are sequentially arranged on the measuring base 1. A first mounting groove 17 is provided on one side of the second positioning member 3 close to the positioning block 10, and a second mounting groove 18 is provided on one side of the positioning block 10 close to the second positioning member 3. One end of the compression spring 16 is arranged in the first mounting groove 17, and the other end of the compression spring 16 is arranged in the second mounting groove 18.

[0035] As Figure 1 , Figure 2 and Figure 3 As shown in Figure 1 , Figure 2 , Figure 3 , a compression spring 16 is provided on the lighter measuring device of the present application. The positioning clamping force of the first positioning surface 4 and the second positioning surface 5 on the variable positioning groove 7 on the lighter can be adjusted through the compression spring 16. Specifically, the first positioning member 2, the second positioning member 3, and the positioning block 10 are sequentially arranged on the measuring base 1 in order. Since the second positioning member 3 and the positioning block 10 are adjacent to each other, a first mounting groove 17 is provided on one side of the second positioning member 3 close to the positioning block 10, and a second mounting groove 18 is provided on one side of the positioning block 10 close to the second positioning member 3. The first mounting groove 17 and the second mounting groove 18 are arranged in alignment along the first direction. Therefore, one end of the compression spring 16 is installed in the first mounting groove 17, and the other end of the compression spring 16 is installed in the second mounting groove 18. When the lighter is clamped in the variable positioning groove 7 on the measuring base 1, the elastic force of the compression spring 16 acts on the second positioning member 3, and the second positioning member 3 gives the lighter a force, so that the lighter is reliably limited in the variable positioning groove 7.

[0036] In one of the embodiments, a first threaded hole 19 is provided on the positioning block 10, and a positioning bolt 20 is disposed in the first threaded hole 19. The axis of the first threaded hole 19 is along the first direction.

[0037] To prevent the acting force of the compression spring 16 from being too large and causing clamping damage to the surface of the lighter, a positioning bolt 20 is provided on the positioning block 10 to limit the elastic force of the compression spring 16 through the positioning bolt 20. Specifically, as Figure 1 and Figure 2 shown, a first threaded hole 19 is provided on the positioning block 10. The axis of the first threaded hole 19 is along the first direction. The first threaded hole 19 is threadedly connected with a positioning bolt 20. Therefore, the axis of the positioning bolt 20 is also along the first direction. Since the positioning bolt 20 is threadedly connected to the positioning block 10, the positioning bolt 20 can be rotated to adjust the distance between the end of the positioning bolt 20 and the positioning block 10, which is equivalent to adjusting the maximum elastic force generated by the compression spring 16. When the user clamps the lighter and the second positioning member 3 contacts the end of the positioning bolt 20, it means that the maximum pressure that the lighter can withstand is reached at this time, and the user can stop applying clamping pressure to the lighter to prevent clamping damage to the surface of the lighter. In addition, the user can also observe the distance between the second positioning member 3 and the positioning bolt 20. When the second positioning member 3 is about to contact the positioning bolt 20, the user can stop applying clamping pressure to the lighter. Among them, as Figure 1 and Figure 2 shown, two first threaded holes 19 and positioning bolts 20 can be provided and symmetrically arranged on the positioning block 10.

[0038] In one of the embodiments, a support seat 21 is provided on the measuring base 1, a second threaded hole 22 is provided on the support seat 21, and an adjusting bolt 23 is disposed in the second threaded hole 22. The adjusting bolt 23 cooperates with the first positioning member 2 to convert its rotational motion into a linear motion of the first positioning member 2 along the first direction.

[0039] The positioning and clamping force of the first positioning surface 4 and the second positioning surface 5 on the variable positioning groove 7 for the lighter is adjusted by the adjusting bolt 23. Specifically, as Figure 1 、 Figure 2 and Figure 3As shown, a support base 21 is provided on the measuring base 1, and a second threaded hole 22 is provided on the support base 21. Preferably, the axis of the second threaded hole 22 is along the first direction. An adjusting bolt 23 is threadedly connected in the second threaded hole 22. Therefore, the axis direction of the adjusting bolt 23 is along the first direction. The adjusting bolt 23 cooperates with the first positioning member 2 to convert the rotational movement of the adjusting bolt 23 around its axis into a linear movement of the first positioning member 2 along the first direction, thereby realizing the sliding of the first positioning member 2 on the measuring base 1. That is, the sliding of the first positioning member 2 on the measuring base 1 is realized through the adjusting bolt 23. When it is necessary to clamp the lighter, for example, when it is necessary to stand the lighter on the measuring base 1 to measure the size of the pattern on the top surface of the lighter, the adjusting bolt 23 needs to be rotated so that the first positioning member 2 slides on the measuring base 1 and the sliding rod 11, and the distance between the first positioning member 2 and the second positioning member 3 is greater than the thickness of the lighter. Then the lighter is placed in the variable chute 8 formed by the first positioning surface 4, the second positioning surface 5 and the third positioning surface 6. The third positioning surface 6 supports the bottom surface of the lighter. Rotate the adjusting bolt 23 again so that the first positioning member 2 moves closer to the second positioning member 3, and the lighter moves closer to the second positioning member 3 on the third positioning surface 6 until both the first positioning surface 4 and the second positioning surface 5 are in contact with the front and back surfaces of the lighter. Continue to rotate the adjusting bolt 23 so that the lighter moves further in the direction of the positioning block 10 under the clamping of the variable positioning groove 7 on the third positioning surface 6. At the same time, both the first positioning member 2 and the second positioning member 3 move towards the positioning block 10, and the compression spring 16 is compressed between the positioning block 10 and the second positioning member 3. The elastic force generated by the compression spring 16 is transmitted to the lighter. The elastic force of the compression spring 16 is always equal to the clamping force of the first positioning surface 4 and the second positioning surface 5 on the front and back surfaces of the lighter. When the clamping force between the lighters reaches the clamping force required by the user, the user can stop rotating the adjusting bolt 23. The lighter is positioned and clamped in the variable positioning groove 7 under the action of the compression spring 16, so that when measuring the top surface of the lighter, the lighter will not be displaced and affect the measurement result. Similarly, when it is necessary to measure other sides of the lighter, turn the lighter so that the surface to be measured is facing up, rotate the adjusting bolt 23 so that the variable positioning groove 7 can accommodate the lighter, and the surface of the lighter opposite to the surface to be measured can be placed on the third positioning surface 6, and then the lighter can be clamped by rotating the adjusting bolt 23. A scale 31 can be provided on the third positioning surface 6 of the measuring base 1. The corresponding scale on the side of the second positioning member 3 close to the positioning block 10 corresponds to the elastic force generated by the compression spring 16 on the second positioning member 3, that is, the elastic force generated by the second positioning surface 5 on the second positioning member 3 on the lighter. The elastic force is directly marked on the scale 31, so that the user can determine the elastic force generated by the compression spring 16, that is, determine the clamping force borne by the lighter.Among them, the two largest surfaces of the lighter are the front and rear surfaces, the distance between the front and rear surfaces is called the thickness, the two smallest surfaces among the six surfaces of the lighter are the top surface and the bottom surface, the distance between the top surface and the bottom surface is called the height, and the two surfaces other than the front and rear surfaces, the top surface, and the bottom surface are the two side surfaces, and the distance between the two side surfaces is called the width.

[0040] In one embodiment, an intermediate connecting portion 24 is provided on the adjusting bolt 23, and a handle 25 is provided on the intermediate connecting portion 24.

[0041] For the convenience of the user's operation, a handle 25 is provided on the adjusting bolt 23. Specifically, as Figure 1 and Figure 2 shown, the handle 25 is connected to the adjusting bolt 23 through the intermediate connecting portion 24.

[0042] In one embodiment, a connecting column 26 is provided at one end of the adjusting bolt 23 connected to the first positioning member 2. A connecting end 27 is provided on the first positioning member 2. A cylindrical groove 28 is provided on the connecting end 27. The connecting column 26 is rotatably arranged in the cylindrical groove 28. A blocking portion 29 for preventing the connecting column 26 from disengaging from the cylindrical groove 28 is provided on the connecting end 27.

[0043] The rotational movement of the adjusting bolt 23 is converted into a linear movement of the first positioning member 2 in the first direction to realize the position adjustment of the first positioning member 2 on the measuring base 1 in the first direction. Specifically, a connecting column 26 is provided at one end of the adjusting bolt 23 connected to the first positioning member 2. A connecting end 27 is provided on the first positioning member 2. A cylindrical groove 28 is provided on the connecting end 27. When the adjusting bolt 23 rotates, the connecting column 26 is rotatably arranged in the cylindrical groove 28. As Figure 4 and Figure 5As shown, a blocking portion 29 is further provided on the connection end 27. The connection column 26 is prevented from detaching from the cylindrical groove 28 through the blocking portion 29. Therefore, the connection column 26 can only perform a rotational movement in the cylindrical groove 28, and there is no sliding movement of the connection column 26 relative to the cylindrical groove 28 in the axial direction. The specific working principle is as follows: The user rotates the adjusting bolt 23 through the handle 25, and the adjusting bolt 23 drives the connection column 26 to move. Therefore, the movement of the connection column 26 is a combined movement of rotational movement and linear sliding movement along its axis. The rotational movement of the connection column 26 along its axis is restricted in the cylindrical groove 28, and the linear movement of the connection column 26 along its axis drives the jig base to perform a sliding movement on the operating table in the first direction through the blocking portion 29, so as to realize the position adjustment of the first positioning member 2 on the measuring base 1. In addition, since the adjusting bolt 23 is threadedly connected to the support seat 21, relying on the self-locking function of the thread, when the user does not rotate the adjusting bolt 23, the adjusting bolt 23 will not generate a sliding movement along its axis, and the first positioning member 2 will not generate a sliding movement along its first direction on the measuring base 1. Therefore, there is no need to provide an additional positioning mechanism to prevent the movement of the first positioning member 2 relative to the measuring base 1. Among them, the mass of the handle 25 is relatively light, and its own weight is not sufficient to drive the adjusting bolt 23 to rotate.

[0044] In one embodiment, profiling grooves 30 are provided on both the first positioning surface 4 and the second positioning surface 5, and the profiling grooves 30 on the first positioning surface 4 and the second positioning surface 5 are arranged in alignment along the first direction.

[0045] As Figure 1 、 Figure 2 and Figure 3 shown, profiling grooves 30 are provided on both the first positioning surface 4 and the second positioning surface 5, and the profiling grooves 30 on the first positioning surface 4 and the second positioning surface 5 are arranged in alignment along the first direction. Therefore, when the lighter needs to be placed in the variable positioning groove 7 for clamping and positioning, the surface of the lighter to be clamped can be installed in the profiling groove 30. The profiling groove 30 facilitates the positioning of the lighter and can position the lighter at the position required by the user. In addition, the profiling groove 30 can be set according to the width, height, and thickness of the lighter to match the positioning of the lighter in different states. Different states refer to the placement states of the lighter with its height direction along the vertical direction, width direction along the vertical direction, and thickness direction along the vertical direction.
