Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a detection tool for a composite gas detector. Background Art

[0002] As a gas detection instrument, a composite gas detector can simultaneously detect multiple toxic or flammable gases, including but not limited to H2S (hydrogen sulfide), CO (carbon monoxide), SO2 (sulfur dioxide), and other gases. When the composite gas detector detects that the concentration of combustible gas or toxic and harmful gas exceeds the standard, the instrument will emit an alarm sound and vibrate to alert the staff. Most existing handheld composite gas detectors on the market have a spring clip on the back. The staff uses the spring clip to clamp the composite gas detector to their own clothing, making it easy to carry it to various testing environments for gas detection.

[0003] Since the handheld composite gas detector can only be used by staff holding the composite gas detector and entering the detection environment to detect the gas in the detection environment, when gas detection is required in some dangerous environments, staff are also required to enter the dangerous environment. This detection method has a large safety hazard. In addition, for some small or closed environments that are inconvenient for staff to enter, the above detection method cannot meet actual detection needs. Utility Model Content

[0004] The purpose of this utility model is to provide a detection tooling for a composite gas detector to address the deficiencies of the existing technology. It solves the problem in the existing technology that when gas detection is required in some dangerous environments, workers are required to enter the dangerous environment. This detection method has great safety hazards. In addition, for some narrow or closed environments that are inconvenient for some workers to enter, the above-mentioned detection method cannot meet the actual detection needs.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A detection tool for a composite gas detector includes an installation component for installing the composite gas detector body. The installation component is detachably connected to a connecting rod. The head of the rear connecting rod is detachably connected to the tail of the front connecting rod. The front and rear connecting rods are assembled with each other by head-to-tail docking.

[0007] Furthermore, a protrusion is provided on the head of the connecting rod, and a first groove is provided on the tail of the connecting rod. The front and rear connecting rods are relatively fixed in the vertical direction by inserting the protrusion of the rear connecting rod into the first groove of the front connecting rod. A limiting component is provided on the connecting rod for achieving relative fixation of the front and rear connecting rods in the horizontal direction.

[0008] Furthermore, the limit assembly includes a slide groove arranged on one side of the opening of the first groove, and the connecting rod is slidably connected to a limit block for limiting the protrusion through the slide groove. The limit block is provided with a toggle rod, and one end of the spring is connected to the limit block, and the other end of the spring is connected to the connecting rod. The movement direction of the spring is the same as the sliding direction of the limit block.

[0009] Furthermore, the protrusion and the first groove are T-shaped structures corresponding to each other.

[0010] Furthermore, the head and tail of the connecting rod are both inclined structures with an angle of 45°.

[0011] Furthermore, the mounting assembly includes a mounting seat, which is provided with a slot for installing the composite gas detector body, and a rubber plug for fixing the composite gas detector body is provided above the slot. The mounting seat is connected to an extension rod, and the extension rod is detachably connected to the connecting rod.

[0012] Furthermore, the extension rod is provided with a second groove at the connecting end with the connecting rod, and the relative fixation of the extension rod and the connecting rod in the vertical direction is achieved by inserting the protrusion of the connecting rod into the second groove of the extension rod. The extension rod is provided with a limiting component for achieving relative fixation of the extension rod and the connecting rod in the horizontal direction.

[0029] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0030] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0031] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0033] For easier understanding, see Figure 1 、 Figure 2 and Figure 6This embodiment provides a detection tool for a composite gas detector, including a mounting assembly 1 and a plurality of connecting rods 3. The mounting assembly 1 is used for mounting and fixing the composite gas detector body 2. The mounting assembly 1 is detachably connected to a connecting rod 3. The head and tail of the front and rear connecting rods 3 are detachably connected, and the multiple connecting rods 3 are assembled with each other by butting heads and tails. Before the actual detection operation, the staff first installs the composite gas detector body 2 on the mounting assembly 1, and then assembles the multiple connecting rods 3 with each other in turn by butting heads and tails, and then connects them with the mounting assembly 1, thus completing the assembly of the entire detection tool. By installing the detection tool with the composite gas detector body 2, the staff can detect dangerous environments or spaces that are inconvenient for staff to enter, thereby expanding the detection range of the composite detector body.

[0034] For easier understanding, see Figures 1 to 4 A T-shaped protrusion 31 is provided on the head of the connecting rod 3, and a corresponding T-shaped first groove 32 is opened on the tail of the connecting rod 3. Since the protrusion 31 and the first groove 32 are T-shaped structures corresponding to each other, after the protrusion 31 is inserted into the first groove 32, the front and rear connecting rods 3 can be relatively fixed in the vertical direction. A limit assembly 4 is provided on the connecting rod 3, and the limit assembly 4 is used to realize the relative fixation of the front and rear connecting rods 3 in the horizontal direction, which includes a slide groove 41. The slide groove 41 is opened on the same side as the opening side of the first groove 32. The connecting rod 3 is slidably connected with the limit block 42 through the slide groove 41. The limit block 42 is used to limit the protrusion 31 located in the first groove 32 in the horizontal direction. A toggle rod 43 is provided on the limit block 42. The end of the limit block 42 is fixedly connected to one end of the spring 44, and the other end of the spring 44 is fixedly connected to the connecting rod 3. The movement direction of the spring 44 is in the same direction as the sliding direction of the limit block 42. When the spring 44 is not subjected to external force, the limit block 42 is covered by the spring 44 on the outside of the protrusion 31, thereby limiting the protrusion 31 in the horizontal direction.

[0035] When assembling multiple connecting rods 3, the staff first applies axial pressure to the spring 44 of the first connecting rod 3 through the toggle rod 43 on the first connecting rod 3. The spring 44 contracts after being compressed, driving the limit block 42 of the first connecting rod 3 to slide back in the slide groove 41. At this time, the protrusion 31 of the second connecting rod 3 is inserted into the opening of the first groove 32 of the first connecting rod 3 until the protrusion 31 of the second connecting rod 3 contacts the end of the first groove 32 of the first connecting rod 3, that is, the protrusion 31 of the second connecting rod 3 is completely inserted into the first groove 32 of the first connecting rod 3. The first connecting rod 3 and the second connecting rod 3 are now relatively fixed in the vertical direction; then, the toggle rod 43 on the first connecting rod 3 is released, stopping the pressure on the spring 44 of the first connecting rod 3. The spring 44 releases its elastic potential energy, driving the limit block 42 on the first connecting rod 3 to move forward and reset, covering the outside of the protrusion 31 of the second connecting rod 3, thereby achieving the relative fixation of the first connecting rod 3 and the second connecting rod 3 in the horizontal direction, thus completing the assembly of the first connecting rod 3 and the second connecting rod 3; repeating the above assembly steps, multiple connecting rods 3 can be assembled together end to end. Furthermore, when the limit assembly 4 is actually installed on the connecting rod 3, the spring 44 is designed to be hidden to prevent other external factors from affecting the normal movement of the spring 44.

[0036] For easier understanding, please refer to Figures 1 to 4 The mounting assembly 1 includes a mounting base 11. A slot 12 is provided on the front of the mounting base 11. A rubber plug 13 is provided at the slot 12. The slot 12 corresponds to the spring clip structure on the back of the composite gas detector body 2. The staff completes the installation of the composite gas detector body 2 by clamping the spring clip of the composite gas detector body 2 on the slot 12 of the mounting base 11 and covering the opening of the slot 12 with the rubber plug 13. An extension rod 14 is connected to the back of the mounting base 11. The extension rod 14 is detachably connected to the connecting rod 3. Specifically, a T-shaped second groove 141 is provided at the end of the extension rod 14, that is, at the connecting end of the extension rod 14 and the connecting rod 3. Since the protrusion 31 of the connecting rod 3 and the second groove 141 of the extension rod 14 are T-shaped structures corresponding to each other, after the protrusion 31 is inserted into the second groove 141, the relative fixation of the extension rod 14 and the connecting rod 3 in the vertical direction can be achieved. The extension rod 14 is provided with a limiting assembly 4 that is the same as the connecting rod 3, which is used to achieve relative fixation of the extension rod 14 and the connecting rod 3 in the horizontal direction (the structure of the limiting assembly 4 of the extension rod 14 is the same as the structure of the limiting assembly 4 of the above-mentioned connecting rod 3, and will not be repeated here).

[0037] When the connecting rod 3 and the extension rod 14 are assembled, the staff first applies axial pressure to the spring 44 of the extension rod 14 through the toggle rod 43 on the extension rod 14. The spring 44 contracts after being compressed, driving the limit block 42 of the extension rod 14 to slide back in the slide groove 41. At this time, the protrusion 31 of the connecting rod 3 is inserted into the opening of the second groove 141 of the extension rod 14 until the protrusion 31 of the connecting rod 3 contacts the end of the second groove 141 of the extension rod 14, that is, the protrusion 31 of the connecting rod 3 is completely inserted into the second groove 141 of the extension rod 14, thereby achieving relative fixation of the extension rod 14 and the connecting rod 3 in the vertical direction; then release the toggle rod 43 on the extension rod 14, stop applying pressure to the spring 44 of the extension rod 14, the spring 44 releases its elastic potential energy, driving the limit block 42 on the extension rod 14 to move forward and reset, covering the outer side of the protrusion 31 of the connecting rod 3, thereby achieving relative fixation of the extension rod 14 and the connecting rod 3 in the horizontal direction, that is, completing the assembly action of the extension rod 14 and the connecting rod 3. Furthermore, in order to facilitate the carrying of the staff, the mounting base 11 and the extension rod 14 are detachably connected, and the length of the extension rod 14 is similar to the length of the connecting rod 3, so that they can be conveniently carried together to the testing environment.

[0038] For easier understanding, see Figures 4 to 6 The head and tail of the connecting rod 3, as well as the connection surface between the extension rod 14 and the connecting rod 3, are all inclined structures at a 45° angle. There are two ways to connect the connecting rods 3 to each other and the extension rod 14 to the connecting rod 3: vertical connection and horizontal connection. The staff can switch between the two connection methods at will by simply changing the direction of the connecting rod 3. Through different connection methods, the detection tooling can be extended vertically or horizontally. That is, the same set of detection tooling components can achieve extension effects in multiple directions, improving the practicality of the detection tooling. The connecting rod 3 is provided with an anti-slip sleeve 33. The anti-slip sleeve 33 is a structure that is narrow in the middle and expanded at both ends. It is also provided with anti-slip grooves, which is convenient for staff to hold and meets the various hand sizes of different staff members, further improving the practicality of the detection tooling.

[0039] Although the present invention has been described using the above preferred embodiments, they are not intended to limit the scope of protection of the present invention. Any person skilled in the art may make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention, and the changes and modifications still fall within the scope of protection of the present invention.
