Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The advantage of the fixture for boiler heat exchanger tube of the present invention is: have " n " shape connection box and butt hook, makes this " n " shape connection box have the enclosed construction of movable adjustment, uniform force, and fixed effect is better, and security is higher, easy to use.
As shown in Figure 1, a kind of fixture for boiler heat exchanger tube, comprise a base 1, one " n " shape connection box 2, one screw rod 3, one operating grip 4 and a movable holddown 5, as shown in Figure 2, this base 1 is provided with two the first engaging lugs 11, as shown in Figure 3, the middle part of being somebody's turn to do " n " shape connection box 2 is provided with a screwed hole 21, as shown in Figure 1, this screw rod 3 be threaded with this screwed hole 21 with this, this operating grip 4 is connected with the upper end of this screw rod 3 is mutually vertical, lower end and this movable holddown 5 of this screw rod 3 are rotationally connected mutually, as shown in Figure 2, this first engaging lug 11 is provided with one first and connects projection 111, as shown in Figure 3, " n " shape connection box 2 should be provided with one second engaging lug 22, as Fig. 1, shown in Fig. 5, this fixture being used for boiler heat exchanger tube also comprises a butt hook 6, the upper end of this butt hook 6 is provided with one the 3rd engaging lug 61, lower end is provided with one second and connects projection 62, 3rd engaging lug 61 is rotationally connected mutually with this second engaging lug 22, this first connects projection 111 and second is connected projection 62 with this and mutually engages, the one end of being somebody's turn to do " n " shape connection box 2 is connected with this first engaging lug 11.When this butt hook 6 is opened, this " n " shape connection box 2 can be rotated, can avoid from the end of heat exchanger tube, heat exchanger tube being inserted in this " n " shape connection box 2, when this butt hook 6 is fastened, enclosed construction should be had by " n " shape connection box 2, and use safer.
As shown in Figure 1 and Figure 2, this base 1 is provided with two lower clamping plates 12 be arranged in parallel, as shown in Figure 4, this movable holddown 5 is provided with clamping plate 51 on, this lower clamping plate 12 and on this clamping plate 51 be " V " shape structure, as shown in Figure 1, Figure 2, Figure 4 shows, these two lower clamping plates 12 with this on the interlaced layout of clamping plate 51; Interlaced arrangement can effectively prevent heat exchanger tube from sliding, and reaches better fixed effect.
As shown in Figure 2, Figure 4 shows, this lower clamping plate 12 and on this surface uniform of " V " shape structure of clamping plate 51 be provided with anti-slop serrations; Further raising skidproof effect.
As shown in Fig. 1, Fig. 3, Fig. 4, the left and right sides of being somebody's turn to do " n " shape connection box 2 is respectively arranged with a guide plate 23, and the two ends of this movable holddown 5 are respectively arranged with a gathering sill 52, and this guide plate 23 is slidably connected mutually with this gathering sill 52; Arranging this guide plate and guide groove 52 can make this movable holddown 5 can movement more stably, can prevent this movable holddown 5 from rotating simultaneously, thus clamping plate 51 on this can be entered between these two lower clamping plates 12 quickly and accurately.
Below only in one embodiment mentality of designing of the present invention is described, when system allows, the present invention can expand to external more functional module simultaneously, thus expands its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
