Detailed description of the invention
The explanation of following embodiment is graphic with reference to what add, can in order to the specific embodiment implemented in order to illustrate the utility model.The direction term that the utility model is mentioned, such as " on ", D score, "front", "rear", "left", "right", " interior ", " outward ", " side " etc., be only the direction with reference to annexed drawings.Therefore, the direction term of use is in order to illustrate and to understand the utility model, and is not used to limit the utility model.
In the drawings, the unit that structure is similar represents with identical label.
Please refer to Fig. 1, Fig. 1 is the detonation configuration figure of the first preferred embodiment of environmental protection pull head of the present utility model.The environmental protection pull head 10 of this preferred embodiment comprises pull head body 11, self-locking body 12, horse hook 13, pulling-on piece 14, shell fragment 15, shell fragment fixture 16 and cap 17.Wherein pull head body 11 comprises top board 111 and base plate 112, wherein top board 111 is provided with a locating hole 113; Self-locking body 12 is arranged in locating hole 113, for positioning operation to horse hook 13; Horse hook 13 arranges in self-locking body 12; Whether pulling-on piece 14 is arranged between self-locking body 12 and horse hook 13, carry out from latching operation for controlling horse hook 13; Shell fragment 15 is arranged on the upside of horse hook 13, for carrying out spacing to horse hook 13; Shell fragment fixed mount 16 is arranged between shell fragment 15 and cap 17, for being fixed in cap 17 by shell fragment 15; Cap 17 is arranged on the outside of self-locking body 12, horse hook 13, shell fragment 15 and shell fragment fixed mount 16, for the protection of above-mentioned parts.
Wherein self-locking body 12 is fixed on the top board 111 of pull head body 11 by the mode of riveted joint, and cap 17 is fixed on the upper surface of the top board 111 of pull head body 11 by the mode of welding.Although self-locking body 12 does not have and pull head body 11 integrated design like this, also preferably self-locking body 12 can be fixed in the locating hole 113 of pull head body 11, ensure that the service life of this pull head 10.
Meanwhile, because baroque self-locking body 12 is independent parts, and the parts such as pull head body 11, horse hook 13, pulling-on piece 14, shell fragment 15, shell fragment fixed mount 16 and cap 17 are parts relatively simple for structure.Therefore self-locking body 12 is designed to the alloy self-locking body of being convenient to carry out structure processing, as kirsite self-locking body etc.The parts such as pull head body 11, horse hook 13, pulling-on piece 14, shell fragment 15, shell fragment fixed mount 16 and cap 17 can be designed to the stainless steel part not needing electro-cladding, to reduce the harm to environment and operating personnel's health; Self-locking body 12, owing to being arranged in cap 17, does not therefore need to arrange electro-cladding on surface yet.
Preferably, in order to ensure the normal use of the environmental protection pull head 10 of this preferred embodiment, shell fragment fixed mount 16 can be fixed on the inner side of cap 17, as arranged the fixed leg being used for fixation spring tab fixed mount 16 in the inner side of cap 17, or directly shell fragment fixed mount 16 is connected to the inner side of cap 17.
In addition shell fragment fixed mount 16 is provided with at least one the 3rd Access Division, the two ends of shell fragment 15 are provided with at least one the 4th Access Division, 3rd Access Division and the 4th Access Division one_to_one corresponding, 3rd Access Division of shell fragment fixed mount 16 forms the second buckle with the 4th Access Division of shell fragment 15 and is connected, and shell fragment 15 is fastened in cap 17 by the second buckle.Specifically as shown in Figures 2 and 3, shell fragment 15 in fig. 2 has two grooves 151 as the 4th Access Division, and shell fragment fixed mount 16 has two projection pieces 161 as the 3rd Access Division, and the two ends of projection piece 161 form the second buckle with corresponding groove 151 and are connected.Shell fragment 15 in figure 3 has two grooves 152 as the 4th Access Division, shell fragment fixed mount 16 has two projection pieces 162 as the 3rd Access Division, spacing between two projection pieces 162 is less than the spacing between two grooves 152, and therefore projection piece 162 also forms the second buckle with corresponding groove 152 and is connected.Preferably horse hook 13 can be fixed in self-locking body 12 under the extruding of shell fragment 15 like this.
When the environmental protection pull head 10 of this preferred embodiment is assembled, first horse hook 13 and pulling-on piece 14 are installed on pull head body, then shell fragment 15, shell fragment fixed mount 16 are fixed on cap 17, subsequently cap 17 is welded to the upper surface of the top board 111 of pull head body 11, miscellaneous part is arranged in the spatial accommodation of cap 17 and the formation of top board 111 upper surface.
When the environmental protection pull head 10 of this preferred embodiment uses, when pulling-on piece 14 does not have not when pulled, horse hook 13 is projected in slideway by self-locking body 12, thus can stop the slip of chain tooth in slideway.When pulling-on piece 14 is pulled by manpower, horse hook 13 is pulled up under the effect of pulling-on piece 14, thus chain tooth can be free to slide in slideway.Namely the auto-lock function of environmental protection pull head 10 is achieved.
Please refer to Fig. 4, Fig. 4 is the detonation configuration figure of the second preferred embodiment of environmental protection pull head of the present utility model.The environmental protection pull head 20 of this preferred embodiment comprises pull head body 21, self-locking body 22, horse hook 23, pulling-on piece 24, shell fragment 25, shell fragment fixture 26 and cap 27.Wherein pull head body 21 comprises top board 211 and base plate 212, wherein top board 211 is provided with a locating hole 213; Self-locking body 22 is arranged in locating hole 213, for positioning operation to horse hook 23; Horse hook 23 arranges in self-locking body 22; Whether pulling-on piece 24 is arranged between self-locking body 22 and horse hook 23, carry out from latching operation for controlling horse hook 23; Shell fragment 25 is arranged on the upside of horse hook 23, for carrying out spacing to horse hook 23; Shell fragment fixed mount 26 is arranged between shell fragment 25 and cap 27, for being fixed in cap 27 by shell fragment 25; Cap 27 is arranged on the outside of self-locking body 22, horse hook 23, shell fragment 25 and shell fragment fixed mount 26, for the protection of above-mentioned parts.
Wherein self-locking body 22 is fixed on the top board 211 of pull head body 21 by the mode of riveted joint, cap 27 comprises at least one first Access Division, the top board 211 of pull head body 21 comprises at least one second Access Division, wherein the first Access Division and the second Access Division one_to_one corresponding, first Access Division of cap 27 forms the first buckle with the second Access Division of the top board 211 of pull head body 21 and is connected, and cap 27 connects the upper surface being arranged on the top board 211 of pull head body 21 by the first buckle.As shown in Figure 4, cap 27 in the diagram has three projection pieces 271 as the first Access Division, and pull head body 21 has three depressed parts 214 as the second Access Division, and three projection pieces 271 form the first buckle with three depressed parts 214 and are connected.Although self-locking body 22 does not have and pull head body 21 integrated design like this, also preferably self-locking body 22 can be fixed in the locating hole 213 of pull head body 21, ensure that the service life of this pull head 20.
