Specific embodiment

The present invention will be further illustrated below in conjunction with specific embodiments, it should be appreciated that these embodiments are merely to illustrate this Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms also fall within application The appended claims limited range.

It is the utility model structure diagram referring to Fig. 1-, a kind of fire door butt hinge spanner, including hand block 1, hand block 1 Front surface offer first sliding groove 2, the rear side right end of first sliding groove 2 is rotatably equipped with driving gear 3, after first sliding groove 2 Side left end is rotatably equipped with rotary shaft 4, and the lateral wall rear end fixing sleeve of rotary shaft 4 is connected to driven gear 5, driving gear 3 and from The lateral wall engagement of moving gear 5 is equipped with internal tooth conveyer belt 6, and internal tooth conveyer belt 6 is assembled in the internal slide of first sliding groove 2, The lateral wall front end fixing sleeve of rotary shaft 4 is connected to drive bevel gear 7, and the left end of hand block 1 is rotatably equipped with driven wheel of differential 8, And driven wheel of differential 8 and the engagement assembly of drive bevel gear 7, the left surface fixing assembling of driven wheel of differential 8 have universal shaft assembly 9, The left end fixing assembling of universal shaft assembly 9 has sleeve 10.

It here between first sliding groove 2 and rotary shaft 4 is connected by sliding bearing, such rotary shaft 4 can not be first The inside of sliding slot 2 is moved forward and backward.

Universal shaft assembly 9 includes the first connection frame 901, and the first connection frame 901 is securely fitted in a left side for driven wheel of differential 8 Surface, the equal fixing assembling in left end front and rear sides of the first connection frame 901 have the first transverse slat 902, the left end of two the first transverse slats 902 Inside fixing assembling has the first round bar 903, and the lateral wall fixing sleeve of the first round bar 903 is connected to the second round bar 904, the second round bar 904 two sides up and down are rotatably connected to the second transverse slat 905, and the left end fixing assembling of two the second transverse slats 905 has the second connection Frame 906, and the second connection frame 906 is securely fitted in the right side of sleeve 10.

It here is to be connected by sliding bearing between the second round bar 904 and two the second transverse slats 905, such second circle Bar 904 is in the process of movement without departing from two the second transverse slats 905.

When universal shaft assembly 9 is started to work in this programme, two the second transverse slats 905 are first rotated, two transverse slats 905 pass through the Two apertures of the connection frame 906 with moving sleeve 10 rotate the first connection frame 901 towards setscrew and matched connection, and first Connection frame 901 drives the first round bar 903 to rotate around the center of the first connection frame 901 by two the first transverse slats 902, Jin Er One round bar 903 drives the second connection frame 906 and 10 rotation of sleeve by the second round bar 904 and two the second transverse slats 905, in this way should The sleeve 10 of hinge spanner can put in narrow place, convenient that the screw in narrow place is dismantled or installed.

The right end fixing assembling of hand block 1 has telescopic device 11, and telescopic device 11 includes cylinder 111, and a left side for cylinder 111 End is securely fitted in the right end of hand block 1, and the inner sidewall of cylinder 111 offers second sliding slot 112, the inside of second sliding slot 112 Sliding block 113 is slidably connected, the right end fixing assembling of sliding block 113 has cross bar 114, and cross bar 114 runs through cylinder 111.

Move cross bar 114 to the right, the side slip to the right inside second sliding slot 112 of sliding block 113 can stretch entire hinge Spanner can use a hand rotating handles 12, the hand steered firmly cross bar 114 of another when screwing the screw of depths, rather than need Two hands lift hand block 1 and rotating handles 12 simultaneously, more labor-saving in this way.

Fixing assembling has handle 12 in the middle part of the front surface of driving gear 3, and the lateral wall of internal tooth conveyer belt 6 is equipped with anti-slip layer 13, and anti-slip layer 13 is slidedly assemblied in the inside of first sliding groove 2.

Handle 12 can be convenient people and rotate driving gear 3.

Anti-slip layer 13 can prevent internal tooth conveyer belt 16 from touching first sliding groove 2 in rotary course, reduce and pass to internal tooth Send the friction of band 16.

The cross section of 10 inner sidewall of sleeve is interior hexagon.

This sleeve 10 can be convenient rotation outer-hexagonal bolts, be not limited to this in this programme.

First transverse slat 902 is identical with the size shape of the second transverse slat 905.

What universal shaft assembly 9 rotated in this way is more stable, and effect is good.

When utility model works, rotating handles 12, handle 12 drives driving gear 3 to rotate, and driving gear 3 passes through internal tooth Conveyer belt 6 drives 5 rotation of driven gear, and driven gear 5 drives 8 rotation of driven wheel of differential by drive bevel gear 7, and then driven For bevel gear 8 by universal shaft assembly 9 with 10 rotation of moving sleeve, such hinge spanner does not need unitary rotation, can be narrow by space The setscrew at small place is dismantled or installation, improves efficiency.
