Description

Technical Field

[0001] The utility model belongs to the technical field of intrinsically safe interphones, in particular to an intrinsically safe interphone. Background Art

[0002] Intrinsically safe intercom is a type of intercom. Compared with traditional intercom, this type of intercom has more comprehensive functions and higher security.

[0003] Existing intrinsically safe walkie-talkies have multiple functions, such as voice communication, instant messaging, location sharing, etc. Therefore, intrinsically safe walkie-talkies are currently generally suitable for the field of mining production to manage and locate personnel.

[0004] It has been found through long-term use and observation that existing intrinsically safe intercoms are easily sweated during use because the environment in which they are used is relatively closed. When sweat is in contact with the shell of the intrinsically safe intercom for a long time, the shell of the intrinsically safe intercom will be corroded by the sweat, resulting in damage.

[0005] To this end, the utility model provides an intrinsically safe intercom. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the utility model to solve the technical problem is as follows: the utility model describes an intrinsically safe intercom, comprising an intrinsically safe intercom body; a pad is fixedly connected to the side wall of the intrinsically safe intercom body; two groups of limiters are fixedly connected to the side wall of the pad; the two groups of limiters are symmetrically arranged; an elastic band is slidably connected to the middle of the limiter; a first Velcro is arranged on the side wall of the elastic band; a second Velcro is arranged on the inner side wall of one end of the elastic band adjacent to the first Velcro, and through the above structure, sweat on the hands can be adsorbed through the arrangement of the pad, thereby reducing the direct contact between sweat and the shell of the intrinsically safe intercom body. At the same time, by setting two elastic bands, the intrinsically safe intercom body can be fixed for the second time, which reduces the possibility of the intrinsically safe intercom body falling off after long-term use. At the same time, the elastic band can create a certain height difference between the elastic band and the intrinsically safe intercom body, so that when the intrinsically safe intercom body falls off from the hand and falls to the ground, the height difference between the intrinsically safe intercom body and the elastic band can be used to reduce the contact area between the intrinsically safe intercom body and the ground, thereby protecting the intrinsically safe intercom body.

[0008] Preferably, a heat dissipation hole is formed on the side wall of the pad; a dustproof net is fixedly connected to the middle of the heat dissipation hole. Through the above structure, the pad can be prevented from being adsorbed on the rear wall of the intrinsically safe intercom body for a long time, which makes it difficult for the heat of the intrinsically safe intercom body to dissipate, thereby causing the intrinsically safe intercom body to heat up and be damaged. At the same time, by providing a dustproof net, the dust or impurities adsorbed on the rear wall of the intrinsically safe intercom body, which makes it difficult for the heat to dissipate, can be reduced.

[0009] Preferably, two elastic bands are fixedly connected to the middle of the two elastic bands; the two elastic bands are respectively located on the two side walls of the intrinsically safe intercom body; a plurality of through holes are opened in the middle of the two elastic bands; the plurality of through holes are equidistantly distributed. Through the above structure, the two side walls of the intrinsically safe intercom body can be protected, and at the same time, overly close contact can be reduced to prevent overheating.

[0010] Preferably, two groups of fixed bases are fixedly connected to one side wall of the intrinsically safe intercom body away from the pad; the two groups of fixed bases are symmetrically arranged and located at the four corners of the intrinsically safe intercom body; two groups of screws are fixedly connected to the middle of the elastic band; the two groups of screws penetrate the elastic band and are threadedly matched with the fixed base. Through the above structure, when the elastic band is pulled to drive the elastic band to stretch synchronously, one end of the elastic band can be fixed, thereby reducing the elastic band from being over-stretched, which makes it difficult to protect the side wall of the intrinsically safe intercom body.

[0011] Preferably, the side wall of the elastic band is fixed with an anti-skid pad layer; the anti-skid pad layer is located on the opposite side of the second Velcro. Through the above structure, the loosening caused by insufficient friction between the hand and the elastic band when pulling the elastic band can be reduced.

[0012] Preferably, a gauze is fixed to the side wall of the pad; the gauze is in contact with the side wall of the intrinsically safe intercom body. Through the above structure, the pad and the intrinsically safe intercom body are too closely fitted, which reduces the difficulty in heat dissipation.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The intrinsically safe intercom described in the utility model absorbs sweat from the hands through the setting of the pad, thereby reducing the direct contact between the sweat and the shell of the intrinsically safe intercom body, thereby reducing the damage to the shell of the intrinsically safe intercom body. At the same time, by setting two elastic bands, the intrinsically safe intercom body can be fixed for a second time, thereby reducing the falling off of the intrinsically safe intercom body after long-term use. At the same time, the setting of the elastic band can create a certain height difference between the elastic band and the intrinsically safe intercom body, so that when the intrinsically safe intercom body falls off from the hand and falls to the ground, the height difference between the intrinsically safe intercom body and the elastic band is used to reduce the contact area between the intrinsically safe intercom body and the ground, thereby protecting the intrinsically safe intercom body.

[0015] 2. The utility model describes an intrinsically safe intercom, which makes it difficult for the heat of the intrinsically safe intercom body to dissipate by lowering the pad to be adsorbed on the rear side wall of the intrinsically safe intercom body for a long time, thereby causing the intrinsically safe intercom body to heat up and be damaged. At the same time, by setting a dustproof net, it is possible to reduce the situation in which dust or impurities are adsorbed on the rear side wall of the intrinsically safe intercom body, causing the heat to be difficult to dissipate.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 4As shown, an intrinsically safe intercom described in an embodiment of the utility model comprises an intrinsically safe intercom body 1; a backing plate 12 is fixedly connected to the side wall of the intrinsically safe intercom body 1; two groups of limit members 15 are fixedly connected to the side wall of the backing plate 12; the two groups of limit members 15 are symmetrically arranged; an elastic band 13 is slidably connected to the middle of the limit member 15; a first Velcro 14 is provided on the side wall of the elastic band 13; a second Velcro 16 is provided on the inner side wall of one end of the elastic band 13 adjacent to the first Velcro 14. When working, the intrinsically safe intercom body 1 can be used to realize the wireless intercom function. Usually, when using the intrinsically safe intercom body 1, the person in conversation needs to hold the intrinsically safe intercom body 1 and then The user can talk to the receiving end of the intrinsically safe interphone body 1. At this time, as the signal is transmitted, a long-distance conversation can be achieved. At this time, as the user holds the intrinsically safe interphone body 1 for a long time, the sweat of the hand will be adsorbed on the shell of the intrinsically safe interphone body 1. Since the shell of the intrinsically safe interphone body 1 is usually made of plastic, as time goes by, the shell of the intrinsically safe interphone body 1 is eroded by sweat for a long time, which will cause the shell of the intrinsically safe interphone body 1 to corrode, thereby causing damage. At this time, by installing a pad 12 on the rear side wall of the intrinsically safe interphone body 1, the pad 12 can be used to isolate the intrinsically safe interphone body 1 from the hand to a certain extent. At this time, the pad 12 can absorb the sweat of the user's hands, thereby reducing the direct contact between the user's hands and the intrinsically safe intercom body 1. At this time, when the intrinsically safe intercom body 1 is installed, by pulling the elastic band 13, as the elastic band 13 is pulled, the first Velcro 14 and the second Velcro 16 of the inner and outer walls of the elastic band 13 can be adhered together, and the elastic band 13 can be fixed to the side wall of the intrinsically safe intercom body 1. At this time, the two elastic bands 13 are limited and fixed by the limiting member 15 at the same time. Through the above structure, the pad 12 can be set to absorb the sweat of the hands, thereby reducing the direct contact between the sweat and the intrinsically safe intercom body. At the same time, by providing two elastic bands 13, the intrinsically safe intercom body 1 can be fixed for a second time, thereby reducing the possibility of the intrinsically safe intercom body 1 falling off after a long period of use. At the same time, by providing the elastic band 13, a certain height difference can be generated between the elastic band 13 and the intrinsically safe intercom body 1, so that when the intrinsically safe intercom body 1 falls off from the hand and falls to the ground, the height difference between the intrinsically safe intercom body 1 and the elastic band 13 can be used to reduce the contact area between the intrinsically safe intercom body 1 and the ground, thereby protecting the intrinsically safe intercom body 1.

[0024] like Figure 3As shown, the side wall of the pad 12 is provided with a heat dissipation hole 2; the middle part of the heat dissipation hole 2 is fixedly connected with a dustproof net 21. When working, the pad 12 is installed on the rear side wall of the intrinsically safe intercom body 1. At this time, as the pad 12 is installed, the sweat of the hand can be absorbed, thereby reducing the direct contact between the sweat and the intrinsically safe intercom body 1. At this time, the pad 12 is installed on the rear side wall of the intrinsically safe intercom body 1, which will affect the heat dissipation of the intrinsically safe intercom body 1. At this time, by opening the heat dissipation hole 2, the outside wind can be blown to the intrinsically safe intercom body through the heat dissipation hole 2. 1, and at the same time, by setting the dustproof net 21, the dust or impurities from the outside can be reduced from being adsorbed on the rear side wall of the intrinsically safe interphone body 1 through the heat dissipation holes 2. Through the above structure, the pad 12 can be reduced from being adsorbed on the rear side wall of the intrinsically safe interphone body 1 for a long time, thereby causing the heat of the intrinsically safe interphone body 1 to be difficult to dissipate, thereby causing the intrinsically safe interphone body 1 to heat up and be damaged. At the same time, by setting the dustproof net 21, the dust or impurities adsorbed on the rear side wall of the intrinsically safe interphone body 1 can be reduced, causing the heat to be difficult to dissipate.

[0025] like Figure 2 and Figure 3 As shown, two elastic bands 3 are fixedly connected to the middle of the two elastic bands 13; the two elastic bands 3 are respectively located on the two side walls of the intrinsically safe intercom body 1; a plurality of through holes 31 are opened in the middle of the two elastic bands 3; the plurality of through holes 31 are equidistantly distributed. During operation, as the elastic bands 13 are stretched, the elastic bands 3 on the two side walls are also stretched at the same time. At this time, as the elastic bands 3 are stretched, the elastic bands 3 will surround the two side walls of the intrinsically safe intercom body 1. At this time, by opening the through holes 31, the adhesion between the elastic bands 3 and the intrinsically safe intercom body 1 can be reduced, thereby reducing the occurrence of overheating. Through the above structure, the two side walls of the intrinsically safe intercom body 1 can be protected, and at the same time, the overly close contact can be reduced, thereby reducing the occurrence of overheating.

[0026] like Figure 1 and Figure 2As shown, two groups of fixed bases 4 are fixedly connected to one side wall of the intrinsically safe intercom body 1 away from the pad 12; the two groups of fixed bases 4 are symmetrically arranged and located at the four corners of the intrinsically safe intercom body 1; two groups of screws 41 are fixedly connected to the middle of the elastic band 3; the two groups of screws 41 penetrate the elastic band 3 and are threadedly matched with the fixed base 4. When working, the fixed base 4 is installed inside the screw 41, and the screw 41 passes through the elastic band 3. At this time, the screw 41 passes through the elastic band 3 and is connected to the fixed base 4, and the elastic band 3 can be fixed and limited at this time. Through the above structure, when the elastic band 13 is pulled to drive the elastic band 3 to stretch synchronously, one end of the elastic band 3 can be fixed, thereby reducing the elastic band 3 from being over-stretched, which makes it difficult to protect the side wall of the intrinsically safe intercom body 1.

[0027] like Figure 4 As shown, the side wall of the elastic band 13 is fixedly connected with an anti-skid pad layer 5; the anti-skid pad layer 5 is located on the opposite side of the second Velcro 16. When working, the elastic band 13 is stretched, and the first Velcro 14 and the second Velcro 16 are matched, so that the elastic band 13 can be fixed to the middle part of the intrinsically safe intercom body 1. At this time, by providing the anti-skid pad layer 5, the hand can contact the anti-skid pad layer 5 when the elastic band 13 is pulled, thereby increasing the friction between the hand and the elastic band 13. Through the above structure, the loosening caused by insufficient friction between the hand and the elastic band 13 when the elastic band 13 is pulled can be reduced.

[0028] like Figure 3 As shown, the side wall of the pad 12 is fixedly connected with a gauze 6; the gauze 6 is in contact with the side wall of the intrinsically safe intercom body 1. When working, the pad 12 is installed on the rear side wall of the intrinsically safe intercom body 1. At this time, by installing the gauze 6 on the inner side wall of the pad 12, a certain insulation layer can be generated between the pad 12 and the intrinsically safe intercom body 1. Through the above structure, the pad 12 and the intrinsically safe intercom body 1 are too closely fitted, which makes it difficult to dissipate heat.

[0029] like Figure 2 and Figure 3 As shown, there is a gap between the elastic band 3 and the intrinsically safe intercom body 1. Through the above arrangement, the elastic band 3 and the intrinsically safe intercom body 1 can be prevented from being too closely fitted, which may cause difficulty in heat dissipation.

[0030] When working, the intrinsically safe intercom body 1 is used to realize the wireless intercom function. Usually, when the intrinsically safe intercom body 1 is used, the interlocutor needs to hold the intrinsically safe interlocutor body 1 and then speak to the receiving end of the intrinsically safe interlocutor body 1. At this time, with the transmission of the signal, a long-distance conversation can be realized. At this time, as the user holds the intrinsically safe interlocutor body 1 for a long time, the sweat on the hand will be adsorbed on the shell of the intrinsically safe interlocutor body 1. Since the shell of the intrinsically safe interlocutor body 1 is usually made of plastic, as time goes by, the shell of the intrinsically safe interlocutor body 1 is corroded by sweat for a long time, which will cause the shell of the intrinsically safe interlocutor body 1 to be corroded, thereby causing damage. At this time, by using the intrinsically safe interlocutor body 1 A pad 12 is installed on the rear side wall of the machine body 1, and the pad 12 can be used to isolate the intrinsically safe intercom body 1 from the hand to a certain extent. At this time, the pad 12 can absorb the sweat of the user's hand, thereby reducing the direct contact between the user's hand and the intrinsically safe intercom body 1. At this time, when the intrinsically safe intercom body 1 is installed, by pulling the elastic band 13, as the elastic band 13 is pulled, the first Velcro 14 and the second Velcro 16 of the inner and outer walls of the elastic band 13 can be adhered together, and the elastic band 13 can be fixed to the side wall of the intrinsically safe intercom body 1. At this time, the two elastic bands 13 are limited and fixed by the limiting member 15 at the same time, and the pad 12 is installed on the rear side wall of the intrinsically safe intercom body 1. At this time, as the pad 12 is installed, the sweat on the hands can be absorbed, thereby reducing the direct contact between the sweat and the intrinsically safe intercom body 1. At this time, installing the pad 12 on the rear wall of the intrinsically safe intercom body 1 will affect the heat dissipation of the intrinsically safe intercom body 1. At this time, by providing the heat dissipation holes 2, the outside wind can pass through the heat dissipation holes 2 to blow to the rear wall of the intrinsically safe intercom body 1. At the same time, by providing the dustproof net 21, the outside dust or impurities can be reduced from being adsorbed on the rear wall of the intrinsically safe intercom body 1 through the heat dissipation holes 2. As the elastic band 13 is stretched, the elastic bands 3 on the two side walls are also stretched at the same time. At this time, as the elastic band 3 is stretched, the elastic band 3 will surround the two side walls of the intrinsically safe intercom body 1. At this time, through The through hole 31 is provided to reduce the adhesion between the elastic band 3 and the intrinsically safe interphone body 1, thereby reducing the occurrence of overheating. The fixed base 4 is installed inside the screw 41, and the screw 41 passes through the elastic band 3. At this time, the screw 41 passes through the elastic band 3 and is connected to the fixed base 4. At this time, the elastic band 3 can be fixed and limited. The elastic band 13 is stretched, and the first Velcro 14 and the second Velcro 16 are matched to fix the elastic band 13 in the middle of the intrinsically safe interphone body 1. At this time, by providing the anti-skid pad layer 5, the hand can contact the anti-skid pad layer 5 when pulling the elastic band 13, thereby increasing the friction between the hand and the elastic band 13. The pad 12 is installed on the rear side wall of the intrinsically safe interphone body 1.At this time, by installing the gauze 6 on the inner wall of the backing plate 12, a certain insulation layer can be formed between the backing plate 12 and the intrinsically safe intercom body 1.
