Abstract
A sleeve-type spring screw belongs to the technical field of fastening pieces for die assembly of tubular pile steel dies. The sleeve-type spring screw comprises a screw rod and a nut, wherein, the nut is in threaded fit with the screw rod; a sleeve is in sleeve joint with the screw rod; and a spring is arranged between the screw rod and the sleeve. The sleeve-type spring screw with simple structure and reasonable design is convenient to maintain and can be separated; each part can be replaced independently; the use cost can be saved; each part can be changed only by a common worker through pincers; the spring is arranged between the screw rod and the sleeve, so that the close integration of the screw rod and the nut can be enhanced; and the sleeve-type spring screw has the advantages of quick assembly, no loosening of screw, low loss and the like, and can shorten the die assembly time greatly.
Description
Technical field
The utility model belongs to pile tube steel die technical field of fastening, is specifically related to telescopic Spring screws.
Background technique
At present, pile tube is widely used in the foundation engineering of the projects such as all types of industries and civil building basis and harbour, harbour, bridge.In process of production, the pile tube steel die need to be used Spring screws, and existing Spring screws can not split, changes complicatedly, needs the machine shop worker of specialty be with oxygen, electric welding just can change.And labor intensity is high, and is time-consuming, take a lot of work, and working life is short, increases cost.
The model utility content
For the problem that prior art exists, the purpose of this utility model is to design the technological scheme that telescopic Spring screws is provided.
Described telescopic Spring screws is characterized in that comprising screw rod and the nut that is equipped with screw flight, and on described screw rod, socket arranges sleeve, between described screw rod and sleeve, spring is set.
Described telescopic Spring screws is characterized in that being fixedly installed ring washer on described screw rod, and described ring washer is separated into linkage section and thread section to screw rod.
Described telescopic Spring screws is characterized in that described spring socket is arranged on the screw flight section.
Described pile tube punching block closes the film Spring screws, it is characterized in that being fixedly installed on described sleeve wear-resisting seat.
Described pile tube punching block closes the film Spring screws, it is characterized in that described nut is fixedly installed in lower spiral shell seat.
Above-mentioned telescopic Spring screws, simple in structure, reasonable in design, easy to maintenance, but split, each part can be changed separately, saves user cost, only need the common laborer to take pliers just can change, and between screw rod and sleeve, spring is set, strengthens combining closely of screw rod and nut, have quick assembling, greatly shorten the matched moulds time, the screw advantages such as loss is few that do not get loose.
Description of drawings
Fig. 1 is use status architecture schematic diagram of the present utility model;
Fig. 2 is the structural representation of screw rod in the utility model.
In figure: the 1-screw rod; The 101-linkage section; The 102-ring washer; The 103-thread section; The wear-resisting seat of 2-; The 3-sleeve; The 4-spring; The 5-punching block; The 6-nut; Spiral shell seat under 7-.
Embodiment
Further illustrate the utility model below in conjunction with Figure of description.
As shown in the figure, telescopic Spring screws comprises screw rod 1, nut 6, sleeve 3 and spring 4.Screw rod 1 and nut 6 screw-thread fit settings, in order to increase the steadiness of nut 6, nut 6 is fixedly installed in lower spiral shell seat 7.Be fixedly installed ring washer 102 on screw rod 1, ring washer 102 is separated into linkage section 101 and thread section 103 to screw rod 1.On screw rod 1, socket arranges sleeve 4, and the linkage section 103 of screw rod 1, ring washer 102 and thread section 103 run through whole sleeve 4.Between screw rod 1 and sleeve 3, spring 4 is set, spring 4 sockets are arranged on the thread section 103 of screw rod 1, have strengthened combining closely of screw rod 1 and nut 6, have quick assembling, greatly shorten the matched moulds time.In addition in order to strengthen the wear resistance between screw rod 1 and sleeve 3, be fixedly installed wear-resisting seat 2, longer service life on sleeve 3 tops.
During installation, screw rod 1 passes punching block 5 and contacts with nut 6 and coordinate, and rotary screw 1 makes the thread section 103 of screw rod 1 fix with nut 6 screw threads.Between screw rod 1 and sleeve 3, spring 2 is set, spring 2 sockets are arranged on the thread section 103 of screw rod 1, can really effectively improve screw rod 1 and screw rear loosening effect, improve the quality of product.
Shown in the above and figure is only preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
