Background technology
Have a plurality of cover shoe last or hat block operations in the technique of shoemaking flow process, be about to the semi-finished product shoe cover in footwear mould shoe last, shoe tree and product shoes are made the as a whole follow-up shoe-making process of proceeding again.
Existing last complex structure, staff's operating difficulties of cover shoe last or hat block, and can not be fully when the last clamping last being clamped, when the operator overlaps shoe last or hat block once firmly producing displacement or loosening phenomenon.
The utility model content
The purpose of this utility model is the above-mentioned defect for prior art, and a kind of last structure is provided.
for solving the above-mentioned defect of prior art, technical scheme to be solved in the utility model is: a kind of last structure, comprise the shoe tree that is formed by heel mould and sole mould, shoe tree is fixedly arranged on a clamping device, the joint face middle part of described heel mould and sole mould is equipped with the slide rail of mutual clamping, the link of described heel mould and described clamping device is provided with the first conduit, described clamping device comprises connector and clamping element, one end of the corresponding described heel mould of described connector is provided with the second conduit that is connected with described the first conduit, both sides, the lower end level of described clamping element extends outward a projection, the both sides of described clamping element are respectively equipped with a plurality of the second grooves that are connected with clamping device, be provided with a push rod in described the first conduit, described push rod end is provided with a push pedal, the position of the corresponding described push pedal of described clamping element is provided with two corresponding shell fragments.
As a kind of improvement of the utility model last structure, the both sides of described connector are interval with respectively a plurality of projections.Both sides at connector arrange projection, have conveniently helped the vamp of shoestring to carry out fastening, shoestring is tied up on projection, and can be prevented the function of vamp distortion.
As a kind of improvement of the utility model last structure, the other end of described connector is inclined upwardly and is extended a baffle plate by bottom, and the end of described baffle plate is provided with an inserted link.Shoestring is tied up when the projection and needed first around bundling to latch again.
As a kind of improvement of the utility model last structure, the both sides of described connector are interval with respectively two projections, and two projections can be according to the difference of shoestring, and chosen distance more closely or projection far away, prevents that shoestring from falling short of and can't tighten.
As a kind of improvement of the utility model last structure, the both sides of described clamping element are respectively equipped with 2 the second grooves that are connected with clamping device.
As a kind of improvement of the utility model last structure, the joint face of described heel mould and sole mould is respectively equipped with plastic plate.Plastic plate increases the wearability of heel mould and sole mould.
Compared with prior art, the utility model has the advantages that: the utility model adopts shoe tree to be connected with a clamping device, by clamping device, shoe tree is fixed on cover shoe last or hat block work station, the handled easily workman overlaps shoe last or hat block, adopt the through hole that arranges in projection to be connected with the inserted link at production work station, the utility model firmly is fixed on cover shoe last or hat block work station.The utility model is simple in structure, and is easy to operate, is highly suitable for overlapping on the shoe last or hat block work station.

Fig. 2 is the utility model reverse side structural representation.
Attached number in the figure title: 1, shoe tree 2, heel mould 3, sole mould 4, clamping device 5, the first conduit 6, push rod 7, push pedal 8, shell fragment 9, plastic plate 41, connector 42, clamping element 43, the second conduit 44, projection 45, the second groove 46, projection 47, baffle plate 48, inserted link.
The specific embodiment
Below just with reference to the accompanying drawings the utility model is further described.
as depicted in figs. 1 and 2, a kind of last structure, comprise the shoe tree 1 that is formed by heel mould 2 and sole mould 3, shoe tree 1 is fixedly arranged on a clamping device 4, the joint face middle part of heel mould 2 and sole mould 3 is equipped with the slide rail of mutual clamping, heel mould 2 is provided with the first conduit 5 with the link of clamping device 4, clamping device 4 comprises connector 41 and clamping element 42, one end of the corresponding heel mould 2 of connector 41 is provided with the second conduit 43 that is connected with the first conduit 5, both sides, the lower end level of clamping element 42 extends outward a projection 44, the both sides of clamping element 42 be respectively equipped with 2 be connected with clamping device the second groove 45, be provided with a push rod 6 in the first conduit 5, push rod 6 ends are provided with a push pedal 7, the position of the corresponding push pedal 7 of clamping element 42 is provided with two corresponding shell fragments 8, two corresponding shell fragments 8 are used for chucking push pedal 7.
Wherein, the both sides of connector 41 are interval with respectively 2 projections 46.2 projections 46 are set in the both sides of connector 41, have conveniently helped the vamp of shoestring to carry out fastening, shoestring is tied up on projection 46, and can prevent the function of vamp distortion.Two projections 46 can be according to the difference of shoestring, and chosen distance more closely or projection 46 far away, prevents that shoestring from falling short of and can't tighten.
The other end of connector 41 is inclined upwardly and is extended a baffle plate 47 by bottom, and the end of baffle plate 47 is provided with an inserted link 48.Shoestring is tied up when the projection 46 and needed first around bundling to inserted link 48 again.
The joint face of heel mould 2 and sole mould 3 is respectively equipped with plastic plate 9, and plastic plate 9 increases the wearability of heel mould 2 and sole mould 3.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the utility model is not limited to the specific embodiment disclosed and described above, to modifications and changes more of the present utility model, also should fall in the protection domain of claim of the present utility model.In addition, although used some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
