Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] See Figures 1 to 6 The first aspect of this application provides a detachable handle bevel fitting and fixing structure, including handle body 1.
[0034] The handle body 1 has a handle fixing protrusion 11 at its bottom. That is, the lower part of the handle body 1 is composed of the handle fixing protrusion 11. The handle fixing protrusion 11 can be a strip structure, for example, it can be rectangular. Below the handle fixing protrusion 11 is a protrusion region 12, the perimeter of which gradually decreases from the top edge to the bottom surface, forming a protrusion slope 13. For example, the protrusion region 12 can be a trapezoid or other polygonal structure. It should be noted that the area of the horizontal cross-section at the top of the protrusion region 12 is larger than the area of its bottom surface, thus forming a shape that is larger at the top and smaller at the bottom, resulting in a sloped sidewall, i.e., the protrusion slope 13.
[0035] When the top of the gas leak detection imaging device body 2 is provided with a fixing area for fixing the handle body 1, and the inner walls of the fixing area 21 are inclined, when the fixing inclined surface is assembled with the boss inclined surface 13, the fixing inclined surface can adjust the assembly direction of the boss inclined surface 13 of the boss area 12 so that the bottom surface of the boss area 12 is aligned with the bottom surface of the fixing area 21.
[0036] It should be noted that when the handle body 1 is assembled with the gas leak detector imager body 2, the boss slope 13 not only serves as a guide (when the fixing area 21 of the gas leak detector imager body 2 used to fix the handle body 1 also has a slope, the two slopes can cooperate to guide the movement direction of the handle body 1), that is, if the side wall of the boss area 12 below the handle fixing boss 11 is a vertical straight wall, if it is to be assembled with the gas leak detector imager body 2, and the fixing area 21 of the gas leak detector imager body 2 also has a straight wall, the two need to be aligned before assembly, which adds an alignment step. When the boss area 12 is trapezoidal, the area at the bottom is small, while when the fixed area 21 of the gas leak detection imager is inclined, the area at the opening end is large. This makes alignment easier. After alignment, when the boss area 12 moves within the fixed area 21 of the gas leak detection imager body 2, since both are inclined, the inclined surfaces can guide the movement of the bottom surface of the boss area 12 after they come into contact, so that the bottom surface of the boss area 12 automatically aligns with the bottom surface of the fixed area 21. After the two are assembled, the bottom surface of the boss area 12 will come into contact with the bottom surface of the fixed area 21.
[0037] In addition, when the boss area 12 and the inclined surface of the fixed area 21 come into contact, the direction of the force formed by the contact of the two inclined surfaces is perpendicular to the inclined surface. When the boss area 12 and the fixed area 21 are fixed by screws, the force of the two is perpendicular to each other. The different directions of the forces can effectively reduce the problem of handle shaking.
[0038] In one embodiment, the handle fixing boss 11 has multiple spaced first screw holes 14 along its length. The first screw holes 14, in conjunction with screws, secure the handle body 1 to the gas leak detector imager body 2.
[0039] Specifically, the number of first screw holes 14 can be set according to the length of the handle fixing boss 11. For example, the number of first screw holes 14 is two.
[0040] In one embodiment, a detachable handle bevel fitting fixing structure further includes a screw, which is screwed into a first screw hole 14 so that the screw passes through the first screw hole 14 and can be screwed into the fixing area 21 on the top surface of the gas leak detection imager body 2 for fixing the handle body 1.
[0041] Specifically, the screw passes through the first screw hole 14 and is screwed into the fixing area 21 of the gas leak detection imager body 2, thus fixing the handle body 1 and the gas leak detection imager body 2. For example, the screw can be a captive screw 3. This way, even if the handle body 1 is separated from the gas leak detection imager body 2, there is no need to worry about the screw separating from the handle body 1, avoiding the problem of screw loss. At the same time, it also facilitates the assembly of the handle body 1 and the gas leak detection imager.
[0042] In one embodiment, the bottom surface of the protrusion region 12 adjacent to the gas leak detection imager body 2 is partially concave to form a concave structure 15; the fixed region 21 is partially convex to form a convex structure 22, so that when the protrusion region 12 and the fixed region 21 are assembled, the concave structure 15 and the convex structure 22 are aligned.
[0043] Specifically, the concave structure 15 has several grooves with openings facing the main body 2 of the gas leak detection imager, and the concave region 15 between adjacent grooves has a first screw hole 14.
[0044] It should be noted that the concave structure 15 refers to the formation of a concave area in the center of the bottom surface of the protruding area 12, so that the center of the bottom surface of the protruding area 12 is separated from the bottom surface of the fixed area 21 of the gas leak detection imaging instrument body 2 by a certain distance. In this way, when the center of the bottom surface of the fixed area 21 protrudes upward to form a protruding structure 22, the protruding area is embedded in the concave area 15, forming an interlocking fit with the protruding area 12.
[0045] Next, when the concave structure 15 has several grooves, the grooves not only reduce weight but also form a receiving space. For example, the description uses two first screw holes 14; when there are multiple screw holes, the number of grooves can be adjusted as needed. When there are two first screw holes 14, the several grooves include at least two groove groups, each groove group including a first groove 16 and a second groove 17, with the first groove 16 and the second groove 17 separately disposed on both sides of the first screw hole 14. Figure 6As shown, one of the two first screw holes 14 has a first groove 16 on its left and a second groove 17 on its right, with the groove wall between the first groove 16 and the second groove 17 serving as the screw hole; the other of the two first screw holes 14 has a second groove 17 on its left and a first groove 16 on its right. Thus, the groove between the two first screw holes 14 is the second groove 17, and the groove outside the two first screw holes 14 is the first groove 16. As mentioned above, the openings of the grooves face downwards, forming a receiving space when they enclose the bottom surface of the fixed area 21. At this time, if a rubber pad (not shown in the figure) is placed in the receiving space, that is, the groove is filled with a rubber pad, it can be ensured that the groove and the bottom surface of the fixed area 21 are filled with a rubber pad, thus preventing gaps from causing gas leaks. After the gas leak detection imaging device body 2 and the handle body 1 are assembled, it plays a role in sealing and buffering the assembly collision force.
[0046] In one embodiment, when the concave structure 15 abuts against the convex structure 22, there is a certain distance between the adjacent surfaces of the protruding area 12 and the fixed area 21; or, when the adjacent surfaces of the protruding area 12 and the fixed area 21 abut against each other, there is a certain distance between the concave structure 15 and the convex structure 22. This ensures a perfect fit for any type of end-face mating, fixing the handle body 1 and the gas leak detector body 2 without any gaps or wobbling.
[0047] This application also provides a gas leak detection imager, including a gas leak detection imager body 2 and the aforementioned detachable handle inclined surface fixing structure; wherein,
[0048] The top of the gas leak detection imaging device body 2 is provided with a fixing area 21 for fixing the handle body 1. The inner walls of the fixing area 21 are inclined to form a fixing inclined surface. When the gas leak detection imaging device body 2 and the detachable handle inclined surface are assembled together, the fixing inclined surface can adjust the assembly direction of the boss inclined surface 13 of the boss area 12 so that the bottom surface of the boss area 12 is aligned with the bottom surface of the fixing area 21.
[0049] It should be noted that the shape of the inner wall of the fixed area 21 is adapted to the side wall of the boss area 12 so that the inclined surfaces of the two can abut against each other. The bottom surface of the fixed area 21 is provided with the same number of second screw holes 23 as the first screw holes 14. The positions of the second screw holes 23 are opposite to the first screw holes 14. Both second screw holes 23 are located on the protruding structure 22 on the bottom surface of the fixed area 21. Thus, the bottom surface of the fixed area 21 forms an upward protruding structure only where the second screw holes 23 are located, while the other areas are on the same plane as the bottom surface of the fixed area 21. This structure facilitates the cooperation with the first groove 16 and the second groove 17, which helps to seal the accommodating space of the rubber gasket.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
