Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of adjustable hold down gag embodiment for the assembling of the utility model engine truck journal box spring;
Fig. 2 is the use state reference map of adjustable hold down gag embodiment for the assembling of the utility model engine truck journal box spring.
The specific embodiment
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As Figure 1-Figure 2, the adjustable hold down gag of the present embodiment engine truck journal box spring assembling, comprise lower U-shaped 3 that two 2 and two of upper U-shaped of being oppositely arranged are oppositely arranged, the end of the side arm of upper U-shaped 2 is provided with upper clipping claw 20, on the end face of upper U-shaped 2, be provided with the first screwed hole (not shown), the end of the side arm of lower U-shaped 3 is provided with lower claw 30, on the end face of lower U-shaped 3, be provided with the second screwed hole (not shown), the first screwed hole is contrary with the hand of spiral of the second screwed hole, upper U-shaped 2 with corresponding lower U-shaped 3 between be provided with studs 1, the hand of spiral at studs 1 both ends is contrary, the end correspondence of studs 1 is threaded in the first screwed hole and the second screwed hole.
Particularly, the assembling of the present embodiment engine truck journal box spring with adjustable hold down gag in use, two upper U-shaped 2 of being oppositely arranged can be stuck in the installing plate 40 on journal box spring 4 tops from both sides by upper clipping claw 20, two lower U-shaped 3 of being oppositely arranged can be stuck in the installing plate 40 of journal box spring 4 bottoms from both sides by lower claw 30, thereby journal box spring 4 is wrapped in upper U-shaped 2 and lower U-shaped 3 formed spaces, after the studs 1 of both sides is rotated, can drive upper U-shaped 2 of respective side and lower U-shaped 3 mutually close, thereby journal box spring 4 is pushed, complete the compression operation before journal box spring assembling.Owing to adopting studs 1 to realize, compress processing, can be for the journal box spring of different size, by regulating studs 1, make U-shaped 2 and lower U-shaped 3 formed spaces can hold corresponding journal box spring, to strengthen the versatility of adjustable hold down gag for the assembling of the present embodiment engine truck journal box spring.
