Description
Technical field
The utility model relates to the waterproof seal that a kind of cargo tracking device is used.
Background technique
The cargo tracking device is mainly used in goods is followed the trail of, so that the position of Real Time Monitoring goods and transmit mode etc., its general working environment is open-air, is easily drenched with rain or is soaked by rainwater, therefore it is higher to the waterproof sealing performance requirement.Traditional waterproof seal mainly is to use sealing gasket, between box body and lid planar sealing pad is set, and planar sealing pad is clipped between the outer of box body and lid, then by screw fixed bin body and lid.This waterproof seal generally needs larger pressure that planar sealing pad is worked, because pressure is excessive, easily makes box body or lid produce distortion; And planar sealing pad installation location is difficult, and planar sealing pad easily produces and departs from the time of installation, thereby causes sealing effect poor.At present, a kind of new waterproof seal arrangement occurred, it arranges groove by the connecting part at box body and lid, O-ring seals is placed in this groove, and is screwed connection box body and lid.This kind structure has solved the problem that the location is installed, and also improved to a certain extent sealing effect, but waterproof sealing effect still is not fine, leaks than being easier to.
Summary of the invention
The purpose of this utility model is to solve at least one of technical problem that exists in the prior art.
For this reason, the waterproof seal that the utility model provides a kind of cargo tracking device to use, the elastic seal ring that it comprises main body, is installed in the loam cake on the main body and is used for waterproof, elastic seal ring is provided with groove, main body or on cover and be provided with the first projection, the first projection can be inserted in the groove, to seal.
Preferably, on the connecting part of main body or loam cake, also be provided with the containing groove of accommodating elastic seal ring.
Preferably, the side of described the first projection has gradient.
Preferably, the top of described the first convex cross section is semicircle.
Preferably, on the connecting part of described main body and described loam cake, also be provided with some the second projections.
Preferably, the cross section of described the second projection is triangle.
Preferably, described the second projection is 2, and lays respectively at the both sides of described the first projection.
The waterproof seal of using according to the cargo tracking device that provides of the present utility model by cooperating of the groove on the first projection and the elastic seal ring, can be good at installing and locates; And by interference fit, can be adjacent between two sides of the first projection and the sidewall of groove between the first projection and the groove, produce multi-sealed effect, its sealing effect is better, antileaking.

Embodiment
Clearer for technical problem, technological scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further described in detail.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The waterproof seal that a kind of cargo tracking device is used, the elastic seal ring 3 that it comprises main body 1, is installed in the loam cake 2 on the main body 1 and is used for waterproof, elastic seal ring 3 is provided with groove 31, main body 1 or loam cake 2 are provided with the first projection 21, the first projection 21 can be inserted in the groove 31, to seal, as shown in figures 1 and 3.After the first projection 21 was inserted grooves 31, two inwalls of extruding elastic seal ring 3 so that two inwalls of two sides of the first projection 21 and elastic seal ring 3 fit tightly, formed multi-sealedly, and its sealing effect is good.When installing, because the existence of the first projection 21 and groove 31 only needs the first projection 21 and groove 31 are aimed at and can pressing be installed, elastic seal ring 3 can not occur in the process of installing situation about departing from is installed.The first projection 21 can be arranged on the main body 1, also can be arranged on the loam cake 2, only needs to guarantee that the first projection 21 and groove on the elastic seal ring 3 can cooperatively interact gets final product.
In a preferred embodiment of the present utility model, on main body 1 or loam cake 2, also be provided with the containing groove 11 of accommodating elastic seal ring 3, as shown in Figure 2.Elastic seal ring 3 is contained in the containing groove 11, has better guaranteed the accurate installation location of elastic seal ring 3.Equally, containing groove 11 can be arranged on the main body 1, also can be arranged on the loam cake 2.To should be noted that in order making simple for structurely, to be convenient to install, containing groove 11 is installed on the different parts from the first projection 21, and when namely containing groove 11 was installed on the main body 1, the first projection preferably was arranged on the loam cake 2; When containing groove 11 was installed on the loam cake 2, the first projection preferably was arranged on the main body 1.
In a preferred embodiment of the present utility model, the side of the first projection 21 has gradient, so that the first projection 21 can produce interference fit when inserting groove 31.Because the side of the first projection 21 has certain gradient, it can strut the groove 31 on the elastic seal ring 3 after inserting groove 31, and from the bottom to top gradually increase of the adhesive force between the first projection 21 and the groove 31, and sealing effect strengthens gradually.Simultaneously, this set of the first projection 21 more is conducive to the first projection 21 and is assembled in the groove 31 on the elastic seal ring 3.
In a preferred embodiment of the present utility model, the top of the first protruding 21 cross sections is semicircle, as shown in Figure 2.The top cross section of the first projection 21 is set to semicircle, and it can better fit tightly with elastic seal ring 3, and in the situation that intensified pressure, the area of contact of the top of the first projection 21 and elastic seal ring 3 strengthens gradually, and sealing effect can get a promotion.
In order further to promote the sealability of the waterproof seal that cargo tracking device of the present utility model uses, can some the second projections 22 be set in main body 1 or loam cake 2, as shown in Figure 2.In the present embodiment, after the installation, two surperficial interference fit outside the second projection 22 and elastic seal ring 3 upper grooves 31, the second projection 22 is pushed elastic seal ring 3 and is fitted tightly and forms sealing under the combination force effect between loam cake 2 and the body 1, it produces multi-sealed effect with the first projection 21.
As further improvement, the cross section of the second projection 22 is triangle, in the process of installing, for the line face cooperates, is conducive to the second protruding 22 compression elastic seal rings 3 between the second projection 22 and the elastic seal ring 3.
As further improvement, the second projection 22 is 2, and lays respectively at the both sides of the first projection 21, with the pressure of balance the first protruding 21 both sides, prevents that main body 1 or loam cake 2 from producing distortion.
The waterproof seal of using according to the cargo tracking device of the utility model above-described embodiment by cooperating between the groove 33 on the first projection 21 and the elastic seal ring 3, can be good at installing and locates; And pass through interference fit between the first projection 21 and the groove 31, can fit tightly between two sides of the first projection 21 and the sidewall of groove 31, produce multi-layer sealed effect, its sealing effect is better, antileaking.By some the second projections 22 are set, can further improve the sealability of the waterproof seal that cargo tracking device of the present utility model uses.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; therefore, as long as use any modification that the utility model specification and accompanying drawing content do, be equal to and replace and improvement etc., all should be included in protection domain of the present utility model.
