DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without any creative work fall within the protection scope of the present application.

[0033] Please refer to Figure 1As shown, the embodiment provides a quick-release handle for a lung function tester, which is composed of a front shell 1, a rear shell 2, a rotating shaft 3, a clamping key 4, a reset spring 5, a clamping plate, a blowpipe support 7, a sensor 8 and a sensor fixing cover 9. The sensor 8 is an inductive device for the flow rate of the user's blowing, which is assembled in the water pipe support and connected with the main machine through a wire. The front shell 1 is one of the handle housings of the lung function tester, and the rear shell 2 is the other handle housing. The front shell 1 is connected with the rear shell 2 through the rotating shaft 3, so as to realize the clamping and opening between the two. The clamping key 4, the reset spring 5, the clamping plate and the blowpipe support 7 are all fixed on the rear shell 2. The blowpipe support 7 is located between the front shell 1 and the rear shell 2. The blowpipe support is a fixing device for the blowpipe inserted during the use of the lung function tester.

[0034] A sliding groove is formed on the side of the rear shell 2 which is symmetrical to the rotating shaft 3. The clamping key 4 is installed in the sliding groove. The clamping key 4 can slide in the sliding groove. A cylinder is fixedly installed on one side of the clamping key 4. The reset spring 5 is installed on the cylinder, and is located between the clamping key 4 and the side wall of the sliding groove and in contact with the side wall. The clamping plate 6 is installed on the upper part of the sliding groove, as shown in Figure 2 and Figure 3 .

[0035] When the clamping key 4, the reset spring 5 and the clamping plate are installed, the reset spring 5 is installed on the cylinder of the clamping key 4, and then the clamping key 4 is installed in the clamping key groove of the rear shell 2. The clamping plate 6 is fixed by using screws. At this time, the clamping key can smoothly slide along the sliding rail of the rear shell 2, as shown in Figure 2 .

[0036] When the handle is normally used, the front shell 1 rotates along the handle rotating shaft 3. The buckle on the front shell 1 is clamped with the buckle on the clamping key 4. The clamping key 4 is fixed on the rear shell 2, so as to achieve the clamping of the front shell 1 and the rear shell 2.

[0037] When the handle is disassembled, the clamping key 4 is slid. The buckle on the clamping key 4 is separated from the buckle on the front shell 1. The front shell 1 and the rear shell 2 are in an open state, as shown in Figure 2 .

[0038] The sensor 8 is installed on the blowpipe support 7 through a sensor groove. The outer end of the sensor 8 is covered with a fixing cover 9. The sensor 8 can be sleeved into the inside of the fixing cover 9. The fixing cover 9 is clamped and fixed with the blowpipe support 7, as shown in Figure 4 , Figure 5 and Figure 6 . A clamping groove is formed on the side of one end of the blowpipe support 7 where the sensor 8 is installed. A buckle is formed on the outer side wall of the fixing cover 9. The buckle and the clamping groove can be clamped together by rotating the fixing cover 9. The fixing cover 9 is counterclockwise rotated to be clamped and fixed with the blowpipe support 7, as shown in Figure 6 .

[0039] When the sensor is disassembled, the sensor fixing cover 9 is rotated clockwise to be separated from the clamping of the blowpipe support 7, and the sensor fixing cover 9 and the sensor 8 are taken out.

[0040] In a further embodiment, a T-shaped slot 81 is arranged symmetrically on the shell of the sensor 8, and the T-shaped slot 81 is placed upside down, as shown in Figure 7 The T-shaped slot 81 includes a horizontal slot and a vertical slot, and the horizontal slot and the vertical slot are arranged vertically. The vertical slot of the T-shaped slot 81 extends to the top of the sensor 8 and is arranged as an open structure. The inner side wall of the fixing cover 9 is fixedly installed with a clamping block 91. The clamping block 91 is also arranged symmetrically between the two clamping blocks 91 inside the fixing cover 9, and the clamping block 91 can be inserted into the inside of the T-shaped slot 81.

[0041] When the fixing cover 9 is closed, the clamping block 91 is inserted into the inside of the T-shaped slot 81, and then the fixing cover 9 is rotated. The clamping block 91 can slide in the T-shaped slot 81, so that the clamping buckle on the fixing cover 9 and the clamping slot on the blowpipe support 7 are clamped together.

[0042] When disassembled, the fixing cover 9 is rotated in the opposite direction, so that the fixing cover 9 with the clamping block 91 is rotated in the opposite direction in the horizontal slot of the T-shaped slot 81, so that the clamping buckle on the fixing cover 9 and the clamping slot on the blowpipe support 7 are separated, and the fixing cover 9 can be removed. However, under the action of the horizontal slot of the T-shaped slot 81 and the clamping block 91, the clamping block 91 can slide horizontally in the T-shaped slot, so it does not affect the rotation of the fixing cover 9. When the T-shaped slot 81 horizontal slot and the clamping block 91 are clamped together, the sensor 8 and the fixing cover 9 are connected together, and when the fixing cover 9 is removed, the sensor 8 can be directly removed, avoiding the secondary infection of the sensor 8 caused by holding the sensor 8, and also avoiding the influence of the sensor 8 on the replacement personnel.

[0043] When the sensor 8 and the fixing cover 9 need to be separated, the clamping block 91 is only needed to be slid out of the vertical slot part of the T-shaped slot 81, so that the sensor 8 and the fixing cover 9 can be separated.

[0044] The fixing cover 9 provides a pressing force to the sensor 8, so that the sensor 8 is installed more stably.

[0045] The fixing cover 9 and the blowpipe support 7 can also be connected by threads. An internal thread is formed on the inner side wall of the fixing cover 9, and an external thread is formed on the outer side of the end of the blowpipe support 7 where the sensor 8 is installed. The internal thread and the external thread are connected, and the detachable connection of the fixing cover 9 and the blowpipe support 7 can also be achieved.

[0046] A plurality of mounting columns 21 are fixedly installed on the inner bottom of the rear shell 2. The upper part of the mounting column 21 is provided with a clamping joint. A connecting seat 71 is fixedly installed on the side of the blowpipe support 7. A plurality of clamping holes are formed on the connecting seat 71 and connected with the clamping joint, as shown inFigure 1 As shown.

[0047] Put the blowpipe support 7 into the rear shell 2, and make the clamping holes on the blowpipe support 7 and the clamping joints on the rear shell 2 fit together, so as to place the blowpipe support 7 in the rear shell 2, and then buckle the front shell 1 and the rear shell 2 together, and the handle assembly is completed, as shown. Figure 1 As shown.

[0048] In addition to the clamping joints and the clamping holes, the support frame is also used to connect the blowpipe support 7 and the rear shell 2. The annular seat 11 for placing the blowpipe support 7 is installed at the front and rear ends of the interior of the rear shell 2, and the annular seat 11 is located at the pipe opening of the blowpipe support 7, as shown. Figures 8-9 As shown. The two sides of the annular seat 11 are rotatably installed with the support legs 10 through the rotating shafts, two support legs 10 are installed on each annular seat 11, and the two support legs 10 are arranged in a spreader shape. The springs 12 are installed between the two support legs 10, and the springs 12 provide elastic force to the support legs 10.

[0049] The bottom of the rear shell 2 is provided with the sliding groove 22, and the cross section of the sliding groove 22 is T-shaped structure. The bottom of the support leg 10 is arranged in the interior of the sliding groove 22, and when the annular seat 11 is subjected to pressure, the bottom of the support leg 10 can slide in the sliding groove 22, that is, the bottoms of the two support legs 10 slide outward under the action of the pressure, so that the spreader structure between the support legs 10 is larger, thereby moving the annular seat 11 and the blowpipe support 7 downward and locating them in the interior of the rear shell 2, as shown. Figure 8 As shown.

[0050] The inner side wall of the front shell 1 is fixedly installed with the compression ring 13, and when the front shell 1 and the rear shell 2 are closed together, the compression ring 13 provides compression force to the blowpipe support 7. During the buckling of the front shell 1 and the rear shell 2, the compression ring 13 provides pressure to the blowpipe support 7, and with the closing of the front shell 1, the blowpipe support 7 is gradually moved downward, and the bottom of the support leg 10 slides outward in the sliding groove 22 under the action of the compression force, so as to slide to the two ends of the sliding groove 22, and the two support legs 10 are opened to the maximum state. In this state, the spring 12 is stretched to the longest state, thereby fixing the blowpipe support 7.

[0051] In this embodiment, in order to make the support leg 10 more stable when moving to the outermost part, the limit block 23 is fixedly installed at the edges of the two ends of the sliding groove 22

[0052] Moreover, when the front shell 1 and the rear shell 2 are closed together, a triangular support part is formed between the two support legs 10 and the compression ring 13, so that the blowpipe support 7 is more stably installed.

[0053] When the ring-shaped seat 11 is not forced, that is, the blowpipe support 7 is not placed on the ring-shaped seat 11, the spring 12 is in a natural elongation state, the bottom of the support leg 10 is inclined outward, the inclination angle of the support leg 10 is relatively small, the vertical distance between the upper end of the support leg 10 and the bottom of the rear shell 2 is the largest in this state, and therefore the ring-shaped seat 11 is in the highest state.

[0054] When the blowpipe support 7 needs to be taken out, the buckle key 4 is only needed to be slid to open the buckling part of the front shell 1 and the rear shell 2, and the extrusion force of the front shell 1 on the blowpipe support 7 is reduced. Since the spring 12 is in the maximum stretching state when the front shell 1 and the rear shell 2 are buckled together, the spring 12 always provides a pulling force to the support leg 10. When the connecting force between the two shells is removed, the bottom of the support leg 10 is contracted under the action of the spring 12, the distance of the support leg 10 in the vertical direction is increased, the ring-shaped seat 11 and the blowpipe support 7 are moved upward, and the blowpipe support 7 is stretched out of the rear shell 2, thereby facilitating the taking of the blowpipe support 7.

[0055] When the blowpipe support 7 is placed, the ring-shaped seat 11 is in the highest state under the action of the pulling force of the spring 12, and is not located in the interior of the rear shell 2, and therefore it is also relatively convenient to place the blowpipe support 7.

[0056] After the blowpipe support 7 is placed, the front shell 1 is only needed to be closed downward, the pressing ring 13 is in contact with the upper end of the blowpipe support 7, and an extrusion force is provided to the blowpipe support 7, so that the support leg 10 is slid outward.

[0057] In a further embodiment, the pressing ring 13 and the ring-shaped seat 11 are both circular arc structures, and the diameters of the inner rings of the two are the same as the outer diameter of the blowpipe support 7. The blowpipe support 7 is placed on the ring-shaped seat 11 and is tightly attached to the ring-shaped seat 11.

[0058] When the front shell 1 is closed on the rear shell 2, the pressing ring 13 is located directly above the blowpipe support 7 and is in contact with the upper part of the blowpipe support 7. During the closing of the two shells, the blowpipe support 7 and the ring-shaped seat 11 are always in contact with the arc of the pressing ring 13 due to the action of the bottom arc surface of the arc-shaped pressing ring 13.

[0059] Even if the blowpipe support 7 and the ring-shaped seat 11 are deviated during the closing, the blowpipe support 7 and the ring-shaped seat 11 will be slid to the state of being completely attached to the pressing ring 13 under the action of the arc surface of the pressing ring 13, and therefore the pressing ring 13 has the functions of positioning and locating the blowpipe support 7 and the ring-shaped seat 11, so that the blowpipe support 7 and the ring-shaped seat 11 are kept in the normal use state.

[0060] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
