Description

Technical Field

[0001] The invention relates to the technical field of hazardous chemical detectors, in particular to a portable hazardous chemical detector. Background Art

[0002] In the current field of industrial safety and environmental monitoring, the detection of toxic and harmful gases that may exist in the air is crucial, especially in some specific working environments, such as the cabin of a ship. Due to the possible presence of high concentrations of harmful gases, direct entry for detection may pose a serious threat to the health and safety of operators. Therefore, portable hazardous chemical detectors have come into being. These devices are usually equipped with a hose to extend the sensor of the detector to the area to be tested, thereby avoiding direct exposure of operators to potentially dangerous environments.

[0003] However, the existing technology faces a series of challenges in the application process. When it is necessary to conduct gas detection from a high place such as a ship deck to a lower chamber, the operator usually needs to hold the detector with one hand and lower the hose to the area to be tested with the other hand. This operation method is not only cumbersome, but also very easy to cause the detector to fall due to inconvenient operation, causing equipment damage or even personal injury. In order to solve this problem, the existing technology attempts to set a strap on the detector, aiming to fix the detector to the operator's hand through the strap to improve the stability and safety of the operation. However, this solution has little effect in actual application. When lowering the hose, the operator often ignores the fixing function of the strap due to the inconvenience of operation, resulting in the strap being useless. At the same time, after the detection is completed, it is inconvenient for the staff to store the hose, which brings an additional burden to the operator's daily work. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1, reference Figure 1 to Figure 14 , which is the first embodiment of the present invention, and provides a portable hazardous chemicals detector. The portable hazardous chemicals detector includes a main body component 100, including a detector body 101, a connecting tube 102 and a display screen 103. The connecting tube 102 is fixed on one side of the detector body 101, and the display screen 103 is on the other side of the detector body 101.

[0034] The main component 100 is a prior art. The pump body built into the detector body 101 can suck the gas in the air through the connecting tube 102 to detect the components in the air. The display screen 103 is used to display the operation information of the detector body 101.

[0035] The detection assembly 200 is arranged on the detector body 101, and includes a fixing block 201a fixed to one side of the detector body 101, a first connector 201b is clamped in the fixing block 201a, a strap 201c is fixed to one side of the first connector 201b, a second connector 201d is fixed to the other end of the strap 201c, a clamping head 201e is arranged on the surface of the second connector 201d, and a retractable belt 201f is fixed to one side of the clamping head 201e, and the detector A protective shell 201g is fixed to one side of the main body 101, and the telescopic belt 201f slides in the protective shell 201g. An elastic rope 201h is fixed to the end of the telescopic belt 201f, and a sliding rod 201i is fixed to the other end of the elastic rope 201h. A pull rope 201j is fixed to the surface of the sliding rod 201i, and a slider 201k is fixed to the end of the pull rope 201j. A first spring 201l is fixed to one side of the slider 201k, and a driving block 201m is fixed to one side of the slider 201k.

[0036] The fixed block 201a is used to limit the first connecting head 201b, the clamping head 201e is used to limit the second connecting head 201d, the elastic rope 201h is in a stretched state, the detector body 101 is symmetrically provided with two protective shells 201g and two fixed blocks 201a, and the two protective shells 201g are both provided with clamping heads 201e, telescopic belts 201f and elastic ropes 201h, and the sliding rod 201i slides in the two protective shells 201g.

[0037] Through the design of the fixing block 201a, the first connector 201b, the second connector 201d and the clamp 201e, the strap 201c can be quickly connected to the retractable belt 201f, so that the strap 201c can be easily replaced to the other side of the detector body 101, so as to facilitate use by users with different habits.

[0038] The first spring 201l is in a stretched state, and is used to pull the slider 201k. When the detector body 101 needs to be fixed to the user's hand, the strap 201c is first pulled to make the strap 201c leave the detector body 101. At this time, the user's hand is inserted between the strap 201c and the detector body 101, and the hand is in a state of naturally holding the detector body 101. At this time, the strap 201c will be tightly attached to the back of the user's hand. The material of the strap 201c is internal nylon weaving, and there is a layer of silicone on the surface, so as to increase the friction with the back of the user's hand and prevent the detector body 101 from detaching.

[0039] When the strap 201c is pressed against the back of the user's hand, the retractable belt 201f is pulled and moves toward the outside of the protective shell 201g. At the same time, the retractable belt 201f pulls the slide bar 201i through the elastic rope 201h, so that the slide bar 201i pulls the pull rope 201j, so that the pull rope 201j drives the slider 201k to move, and the slider 201k drives the driving block 201m to move.

[0040] Specifically, the detection component 200 also includes a connecting part 202, which is arranged on one side of the detector body 101, including a positioning strip 202a fixed to the surface of the connecting tube 102, and a mounting plate 202b arranged on one side of the detector body 101, and a positioning block 202c is fixed on the inner wall of the mounting plate 202b, and the positioning block 202c is located on one side of the positioning strip 202a.

[0041] The positioning bar 202a is used to limit the positioning block 202c. The positioning block 202c can pass between the two positioning bars 202a. The positioning bar 202a squeezes the positioning block 202c so that the mounting plate 202b is tightly attached to one side of the detector body 101, thereby positioning the mounting plate 202b.

[0042] Specifically, the connecting member 202 also includes a supporting block 202d fixed in the mounting plate 202b, the surface of the supporting block 202d is rotatably connected to a rotating block 202e, one side of the rotating block 202e is fixed with a snap-in block 202f, a positioning groove 101-1 is opened on the surface of the detector body 101, the snap-in block 202f is located in the positioning groove 101-1, and a second spring 202g is fixed to the other side of the rotating block 202e.

[0043] The other end of the second spring 202g is fixed to the inner wall of the mounting plate 202b, and the second spring 202g is in a compressed state. The support block 202d is used to support the rotating block 202e. By pushing the rotating block 202e, the rotating block 202e can squeeze the second spring 202g, thereby driving the end of the clamping block 202f to move out of the positioning groove 101-1, thereby releasing the limit on the mounting plate 202b.

[0044] When installing the mounting plate 202b, it is only necessary to press the positioning block 202c from between the two positioning strips 202a and rotate the mounting plate 202b so that the snap-in block 202f moves to one side of the positioning groove 101-1. At this time, under the elastic force of the second spring 202g, the end of the snap-in block 202f can be snapped into the positioning groove 101-1.

[0045] Specifically, the connecting member 202 further includes an extrusion rod 202h that slides in the mounting plate 202b, a positioning plate 202i is fixed to the surface of the extrusion rod 202h, and a button 202j is fixed to the end of the extrusion rod 202h.

[0046] The positioning plate 202i slides in the mounting plate 202b and is used to limit the extrusion rod 202h. By pressing the button 202j, the button 202j can push the extrusion rod 202h, so that the extrusion rod 202h pushes the rotating block 202e, so that the end of the clamping block 202f moves out of the positioning groove 101-1, thereby releasing the limit on the mounting plate 202b.

[0047] Specifically, the detection component 200 also includes a storage member 203 arranged on one side of the mounting plate 202b, including a storage shell 203a fixed on one side of the mounting plate 202b, a storage rod 203b is rotatably connected to the storage shell 203a, the storage rod 203b is inserted into the connecting tube 102, a driving wheel 203c is fixed to the surface of the storage rod 203b, a conduit 203d is wrapped around the surface of the storage rod 203b, a ventilation groove 203b-1 is opened in the storage rod 203b, the end of the conduit 203d is inserted into the ventilation groove 203b-1, a storage groove 203a-1 is opened on the surface of the storage shell 203a, the other end of the conduit 203d is located in the storage groove 203a-1, and a positioning ring 203e is fixed to the surface of the conduit 203d.

[0048] The storage shell 203a is used to protect the conduit 203d inside it, and the storage rod 203b is used to store the conduit 203d.

[0049] By rotating the driving wheel 203c, the storage rod 203b can be driven to rotate, so that the storage rod 203b can store the catheter 203d on the surface. The setting of the positioning ring 203e can prevent the catheter 203d from completely entering the storage shell 203a, so that a section of the catheter 203d leaks out of the storage shell 203a, thereby facilitating the use of the catheter 203d.

[0050] Optionally, the driving wheel 203c is replaced with an electric driving structure in the prior art, so that the catheter 203d can be stored more quickly.

[0051] The setting of the ventilation groove 203b-1 allows the air in the area to be tested to be transported into the ventilation groove 203b-1 through the conduit 203d, and then transported from the ventilation groove 203b-1 to the connecting pipe 102, thereby entering the sensor of the detector body 101, so as to analyze the components in the air.

[0052] Example 2, reference Figure 1 to Figure 14 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0053] Specifically, the storage component 203 also includes a connecting shell 203f fixed on the surface of the storage rod 203b, a limiting disk 203g is fixed on one side of the connecting shell 203f, a limiting groove 203g-1 is provided on the surface of the limiting disk 203g, an insert block 203h is inserted in the limiting groove 203g-1, the limiting disk 203g is located on one side of the mounting disk 202b, and the insert block 203h slides in the mounting disk 202b.

[0054] By inserting the insert block 203h into the limiting groove 203g-1, the limiting plate 203g will not rotate relative to the mounting plate 202b, so that the storage rod 203b will not rotate, thereby preventing the catheter 203d on the surface of the storage rod 203b from being released.

[0055] Specifically, the detection component 200 also includes an adjustment member 204 arranged in the mounting plate 202b, including an adjustment rod 204a rotatably connected to the mounting plate 202b, a sleeve 204b is slidably connected to the surface of the adjustment rod 204a, an insert block 203h is rotatably connected to the sleeve 204b, a third spring 204c is fixed to one side of the adjustment rod 204a, and the other end of the third spring 204c is fixed to the inner wall of the mounting plate 202b.

[0056] By moving the adjusting rod 204a, the adjusting rod 204a can drive the sliding sleeve 204b to move, so that the sliding sleeve 204b drives the insert block 203h to move out of the limiting groove 203g-1. At this time, the insert block 203h is only inserted into the mounting plate 202b, thereby releasing the limit on the limiting plate 203g, and the third spring 204c is in a stretched state, so that the third spring 204c can pull the adjusting rod 204a.

[0057] Specifically, an adjustment block 204d is slidably disposed in the mounting disk 202b, a fourth spring 204e is fixed in the adjustment block 204d, the other end of the fourth spring 204e is fixed to the inner wall of the mounting disk 202b, an extrusion surface 204d-1 is provided on the surface of the adjustment block 204d, and the end of the adjustment rod 204a is located on the surface of the adjustment block 204d.

[0058] The fourth spring 204e is in a stretched state, and is used to pull the adjustment block 204d, and the adjustment block 204d is used to drive the adjustment rod 204a.

[0059] When the driving block 201m is pulled by the slider 201k, the driving block 201m can push the adjusting block 204d, so that the extrusion surface 204d-1 of the adjusting block 204d squeezes the end of the adjusting rod 204a, so that the adjusting rod 204a drives the insert block 203h to move, so that the insert block 203h moves out of the limiting groove 203g-1, thereby releasing the limit on the limiting plate 203g.

[0060] During use, when the catheter 203d needs to be used for detection, first press the positioning block 202c from between the two positioning strips 202a, and rotate the mounting plate 202b to move the snap-in block 202f to the side of the positioning groove 101-1. At this time, under the elastic force of the second spring 202g, the end of the snap-in block 202f can be snapped into the positioning groove 101-1, thereby fixing the mounting plate 202b.

[0061] Then pull the strap 201c to make the strap 201c leave the detector body 101. At this time, insert the user's hand between the strap 201c and the detector body 101, and the hand will naturally hold the detector body 101. At this time, the strap 201c will be tightly attached to the back of the user's hand to prevent the detector body 101 from falling off.

[0062] When the strap 201c is pressed against the back of the user's hand, the retractable belt 201f is pulled and moves toward the outside of the protective shell 201g. At the same time, the retractable belt 201f pulls the slide bar 201i through the elastic rope 201h, so that the slide bar 201i pulls the pull rope 201j, so that the pull rope 201j drives the slider 201k to move, and the slider 201k drives the driving block 201m to move. When the driving block 201m is pulled by the slider 201k, the driving block 201m can push the adjusting block 204d, so that The extrusion surface 204d-1 of the adjusting block 204d squeezes the end of the adjusting rod 204a, so that the adjusting rod 204a drives the insert block 203h to move, so that the insert block 203h moves out of the limiting groove 203g-1, thereby releasing the limit on the limiting plate 203g, so that the conduit 203d outside the storage shell 203a can be pulled, so that the conduit 203d is released, so as to detect the air in the test area, so that the detector body 101 will not fall when the user adjusts the length of the conduit 203d.

[0063] After the detection is completed, it is only necessary to rotate the driving wheel 203c so that the catheter 203d is wound around the surface of the storage rod 203b, thereby realizing a convenient storage of the catheter 203d.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
