Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
The utility model provides a kind of hand vice for construction opening back-up ring, as shown in Figures 1 to 5, comprise the first tong arm 1 and the second tong arm 2 be hinged by bearing pin 3, wherein, two clamping areas 11,21 that described first tong arm 1 and the second tong arm 2 form jaw are respectively arranged with locating slot 12,22, and the bottom land of this locating slot 12,22 is formed as the curved surface matched with the outer peripheral edge of described split washer.
By technique scheme, make hand vice of the present utility model can be suitable for construction opening back-up ring.Because the bottom land of locating slot and the outer peripheral edge of split washer match, therefore, it is possible to prevent split washer slippage from locating slot, realize the installation of split washer quickly and safely.
Particularly, during use, first split washer is placed into the draw-in groove place on to be installed (as oil connection), then hand vice are moved, the first tong arm 1 is made to support on the outer peripheral edge of split washer, second tong arm 2 is supported on to be installed, ensures that split washer aimed at by the locating slot 12 on the first tong arm 1.In clamping process, the second tong arm 2 keeps motionless, and split washer moves towards the second tong arm 2 with the first tong arm 1, and the locating slot 22 on the second tong arm 2 ensures that split washer has the space of yielding, so that split washer can be in place.
Locating slot 12,22 can be formed in the optional position on clamping area 11,21 accordingly.Such as, described locating slot 12,22 can be formed in the middle part of described clamping area 11,21, to make locating slot 12,22 be formed as U-lag (groove of U-shaped profile), thus can to split washer along hand vice thickness direction move carry out spacing.The middle part of clamping area 11,21 mentioned here refers to the middle part along hand vice thickness direction of clamping area.
Two surfaces relative along its thickness direction of hand vice can be defined as upper surface and lower surface respectively.As a kind of preferred embodiment of the present utility model, as shown in Figure 5, described locating slot 12,22 is formed in the side of the upper surface 4 of the close described hand vice of described clamping area 11,21, to make locating slot 12,22 be formed as L shape groove (groove that cross section is L-shaped), thus can more easily split washer be assembled in locating slot.In this embodiment, more preferably, bottom land and the sidewall of described locating slot 12,22 acutangulate, can ensure that split washer is stably engaged in locating slot while convenient for assembly.
Preferably, described two clamping areas 11,21 are formed as curved surface respectively.Here, by making the clamping area 11 on the first tong arm 1 be formed as curved surface, can ensure that split washer is in place; By making the clamping area 21 on the second tong arm 2 be formed as curved surface, to coordinate with the outer peripheral face of to be installed, can ensure that the second tong arm 2 is stably fastened on to be installed.
Preferably, as shown in figures 1 and 3, described first tong arm 1 is formed with the first pin-and-hole 13 mated with described bearing pin 3, described second tong arm 2 is formed with multiple second pin-and-holes 23 mated with described bearing pin 3.By arranging multiple second pin-and-hole 23 on the second tong arm 2, make it possible to the span of jaw size adjusting hand vice according to the size of to be installed flexibly, the installation of convenient split washer.
Below preferred embodiment of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
