Detailed description of the invention
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not being interpreted as restriction of the present utility model.
As shown in Figures 1 to 5, the installation tapped bore that front drag-hook device of the present utility model is also provided with mounting seat 1 and is arranged on subframe front cross rail 6 except mounting sleeve 2 and towing hook 4, the bar portion of this towing hook 4 has outside thread, and mounting sleeve 2 has the negative thread suitable with outside thread.In the utility model, this mounting sleeve 2 is fixedly connected with mounting seat 1, mounting seat 1 is provided with mounting hole 14, the Demountable that mounting seat 1 is connected with installation tapped bore screw thread fit through mounting hole 14 by hold-down bolt 5 is fixedly mounted on subframe front cross rail 6.
When needs use front drag-hook device of the present utility model, only the mounting seat 1 of carrying mounting sleeve 2 need be fixedly mounted on subframe front cross rail 6 by hold-down bolt 5, then towing hook 4 is threaded connection is fixedly mounted on mounting sleeve 2 and can uses; When without the need to using front drag-hook device of the present utility model; the mounting seat 1 of carrying mounting sleeve 2 can be disassembled to be placed in driver's tool case from subframe front cross rail 6 and deposit; at this; for the ease of depositing front drag-hook device; usually also need again towing hook 4 to be disassembled from mounting sleeve 2; if the space of driver's tool case is enough large certainly, the location mode no longer dismantling towing hook 4 also can be taked.
As can be seen here, front drag-hook device of the present utility model effectively can solve the problem that mounting sleeve is easy to because of outside exposed for a long time be corroded, and then greatly can extend the service life of front drag-hook device; Moreover, because subframe front cross rail relative vehicle longeron, front bumper beam have larger tensile strength, and mounting sleeve is just arranged on subframe front cross rail within the short period used, therefore, front drag-hook device of the present utility model can not have any impact to vehicle body sheet metal.In addition, the mounting sleeve due to front drag-hook device of the present utility model is fixed on subframe front cross rail by mounting seat, therefore, without the need to offering mounting hole on front bumper, and then also can not have any impact to front bumper.
In order to be reduced on subframe front cross rail, installation tapped bore is set on the impact of subframe front cross rail strength and stiffness, as shown in Figures 1 to 5, above-mentioned installation tapped bore can be formed to be installed in threaded line pipe 3, and threaded line pipe 3 is installed runs through subframe front cross rail 6 from top to bottom, and be fixed together with subframe front cross rail 6, this installation threaded line pipe 3 such as can adopt the mode of welding and subframe front cross rail 6 to be fixed together.Like this, when fixedly mounting base 1, hold-down bolt 5 through mounting hole 14 be formed at the installation tapped bore screw thread fit installed in threaded line pipe 3 and be connected, at this, owing to installing the support of threaded line pipe 3, not only can not reduce the strength and stiffness of subframe front cross rail 6 because punching on subframe front cross rail 6, the strength and stiffness of subframe front cross rail 6 in punching place can be increased on the contrary.
For the ease of fixedly mounting base 1 and make, between mounting seat 1 and subframe front cross rail 6, there is higher Joint strenght on subframe front cross rail 6, as shown in Figure 3, above-mentioned mounting seat 1 can comprise the first installation wing 11, second installs the wing 12 and installs the wing 11 and second first and install middle transition portion 13 between the wing 12, middle transition portion 13 installs the wing 11 and described second respectively and installs the wing 12 phase and accept with first at two ends, the first installation wing 11 and the second installation wing 12 respectively arrange an above-mentioned mounting hole 14, accordingly, front drag-hook device of the present utility model should arrange two hold-down bolts 5 and two installation tapped bore, above-mentioned mounting sleeve 2 is then arranged in middle transition portion 13.
For the ease of mounting sleeve 2 is fixed in mounting seat 1, as shown in Figure 3, the inside face in this middle transition portion 13 has the shape suitable with the outside face of mounting sleeve 2, make middle transition portion 13 form the structure of semi-surrounding mounting sleeve 2, this kind of structure is convenient to be fixed in mounting seat 1 by mounting sleeve 2 by the mode of welding.
The centerline direction of above-mentioned mounting hole 14 is preferably orthogonal with the centerline direction of mounting sleeve 2, to be conducive to making the structure of front drag-hook device compacter.
In order to increase mounting seat 1 intensity and and subframe front cross rail 6 between Joint strenght, as shown in Figure 3, the inside face of this mounting seat 1 can be formed in the periphery of mounting hole 14 strengthens boss 15, as shown in Figure 1, Figure 4 and Figure 5, mounting seat 1 is resisted against on the bottom surface of subframe front cross rail 6 by strengthening boss 15.Another effect of this reinforcement boss is, for the ease of installation threaded line pipe 3 is welded in subframe front cross rail 6, the top of installation threaded line pipe 3 can be made protruding relative to subframe front cross rail 6 with bottom, therefore, if be that the bottom being greater than or equal to installation threaded line pipe 3 is relative to the outwardly directed length of subframe front cross rail 6 by the Thickness Design strengthening boss 15, the part of stretching out just can be made to be placed in completely and to strengthen in boss 15, like this, when fixedly mounting base 1, the surface of the surface of reinforcement boss 15 and subframe front cross rail 6 just can be made to fit completely, to increase Joint strenght further.The mode that this reinforcement boss 15 has the brace panel of through hole by welding on the inside face of mounting seat 1 is formed, the through hole of this brace panel and mounting hole 14 up/down perforation.
Structure of the present utility model, feature and action effect is described in detail above according to graphic shown embodiment; the foregoing is only preferred embodiment of the present utility model; but the utility model does not limit practical range with shown in drawing; every change done according to conception of the present utility model; or be revised as the Equivalent embodiments of equivalent variations; do not exceed yet specification sheets with diagram contain spiritual time, all should in protection domain of the present utility model.
