Description

Extension device for hood telescopic mandrel

The present invention relates to an extension device for a telescopic top rod of a hood, in particular to an extension device that is erected between the telescopic top rod and the hood, thereby increasing the opening angle of the hood.

Press, when the engine room of the car is being repaired, the hood must be opened and erected in the open position. As shown in Figure 1, the hood 11 is located in the open position by the top of a telescopic top rod 12. However, In the maintenance process, in order to facilitate the operation, it is often necessary to increase the opening angle of the hood 11. In this case, as shown in FIG. 2, an extension assembly 13 is assembled between the telescopic ejector rod 12 and the hood 11. However, although the aforementioned extension assembly 13 The purpose of increasing the opening angle of the hood 11 can be achieved, but there is still a lack of adjusting the length in use. Since the length cannot be adjusted, in order to apply to most types of automobiles, maintenance operators must prepare a variety of extension components 13 of different specifications. It is necessary to select a suitable extension assembly 13 for each vehicle, which not only causes inconvenience in maintenance, but also increases the purchase cost of the extension assembly 13 .

Therefore, the purpose of the present invention is to provide an extension device for the hood telescopic top rod with adjustable length.

Therefore, the extension device of the telescopic top rod of the hood of the present invention is assembled on the telescopic top rod to extend the length of the telescopic top rod. The hood is provided with a joint, the telescopic top rod The two ends of the telescopic top rod are respectively connected to a vehicle body and the joint to support the hood in the open position. One end of the telescopic top rod can be detached from the joint. The extension device has an extension piece and an adjustment The extension piece includes a socket part that can be sleeved on the telescopic top rod, and a screw extension part extending upward from the socket part, and one end of the adjustment piece is screwed on the screw extension part, The adjustment piece can be screwed relative to the extension part, and the other end of the adjustment piece can be connected to the joint. Since the adjustment piece can be screwed relative to the extension part of the extension piece to adjust the length, the extension device of the present invention can be adjusted. It can be applied to more types of vehicles, which is very convenient in use, and at the same time can save the purchase cost of the extension device.

FIG. 6 is an exploded perspective view of the extension device of the hood telescopic ejector rod according to another preferred embodiment of the present invention.

Referring to Figures 3 and 4, the extension device 3 of the hood telescopic mandrel 2 according to a preferred embodiment of the present invention does not show the hood and the vehicle body in this embodiment, but only shows the one assembled on the hood The joint 4 is connected to the erection head 5 on the car body, and one end of the telescopic mandrel 2 is connected to the car body On the erection head 5, the other end is detachably connected with the joint 4 to support the hood in the open position of the original design of the car. The extension device 3 has an extension piece 6 and an adjustment piece 7, the extension The element 6 includes a sleeve portion 61 that can be sleeved on the telescopic mandrel 2, and a screw extension portion 62 extending upward from the sleeve portion 61. In this embodiment, the screw extension portion 62 is assembled On the socket portion 61, a screw hole 621 is formed inside, but the socket portion 61 and the screw extension portion 62 can also be selected to be integrally processed and formed. The screwed section 71 in the hole 621, and a socket 72 extending from the screwed section 71, the screwed section 71 can be rotated relative to the screw hole 621 to fine-tune the position of the adjustment member 7 relative to the extension member 6, the socket 72 can be sleeved on the joint 4. Under normal conditions, the sleeve part 61 of the extension part 6 and the screw extension part 62 are assembled together with each other, and the screw connection section 71 of the adjustment part 7 is screwed on. The screw hole 621 of the screw extension 62 can be rotated to fine-tune the length.

When the extension device 3 of this embodiment is in use, one end of the telescopic top rod 2 is first detached from the joint 4 , and then the sleeve portion 61 of the extension device 3 is sleeved on the telescopic top rod 2 , and then as described in the first step 5. Rotate the adjusting member 7 as shown in Fig. 5, so that the threaded section 71 can be extended to an appropriate length relative to the threaded portion 62, and then the sleeve 72 is sleeved on the joint 4 to complete the extension of the telescopic top rod 2. During the operation of the hood, the telescopic mandrel 2 and the extension part 62 are pressed against each other at the same time. When disassembling, it is only necessary to detach the sleeve head 72 from the joint 4 and pull out the sleeve part 61. The telescopic mandrel 2 is sufficient. Since the screwing section 71 of the adjusting member 7 can be screwed relative to the screwing portion 62 of the extension member 6 to adjust the length, the extension device 3 of the present invention can be applied to more vehicle types. It is very convenient to use, and at the same time, the purchase cost of the extension device 3 can be saved.

Please refer to FIG. 6 , the extension device 3 of the hood telescopic top rod 2 according to another preferred embodiment of the present invention also has an extension piece 6 and an adjustment piece 7 , and the main difference is that the socket portion 61 has different inner diameters. a first segment 611 and a second segment 612, in this embodiment the second segment The inner diameter of 612 is larger than that of the first section 611, so as to be suitable for the telescopic mandrel 2 with a larger outer diameter. The first section 611 is connected to the screw extension 62, and the second section 612 is sleeved on the On the telescopic top rod 2 , as in the previous embodiment, the purpose of extending the telescopic top rod 2 can be achieved, and the functions of convenient use and reduction of the purchase cost of the extension device 3 can be achieved.
