Being provided with can be with respect to the pushing block of its sliding, and the railroad of the door closer further includes the spring leaf of strip, the spring
Piece includes the fixed section being arranged successively along its length, limit section, and the fixed section is fixed in the mounting base, institute
It states limit section to be partially disposed in the sliding slot and towards arching upward in the sliding slot, the limit section is far from the fixed section
End is against on the pushing block, and the spacing of the pushing block and the fixed section is bigger, then the limit section more enters described
In sliding slot.
Preferably, the lug boss extended towards the spring leaf, the end energy of the lug boss are provided on the sliding block
It is enough to be contradicted with the spring leaf.
It is further preferred that the end of the lug boss is the steel ball being embedded in the sliding block.
Preferably, the length extending direction of the spring leaf is parallel with the direction of motion of the sliding block.
Preferably, the direction of motion of the sliding block is parallel with the direction of motion of the pushing block.
Preferably, supporting walls are provided in the mounting base, the supporting walls are parallel with the direction of motion of the pushing block, institute
Pushing block is stated to be resisted against on the supporting walls far from one end of the spring leaf.
It is further preferred that the pushing block includes the extending direction support portion vertical with the pushing block direction of motion, extends
The end of the direction sliding part parallel with the pushing block direction of motion, the support portion contradicts the cunning on the spring leaf
Dynamic portion contradicts on the supporting walls.
It is further preferred that the adjustment tank that the mounting base has extending direction parallel with the sliding slot, the pushing block is sliding
Movingly it is arranged in the adjustment tank, the adjustment tank constitutes the supporting walls far from the cell wall of the spring leaf.
Preferably, electromagnet apparatus is provided in the mounting base, the electromagnet apparatus is included at least and is fixed at
Electromagnet ontology in the mounting base, the push rod for capableing of the relatively described electromagnet ontology movement, the pushing block are fixed at
On the push rod.
Due to the application of the above technical scheme, the utility model has the advantage that this is practical new compared with prior art
The railroad of the door closer of type can change the degree that spring leaf enters sliding slot by controlling the position of pushing block, spring leaf into
Enter sliding slot volume it is less when, then sliding block can overcome spring leaf elastic force, therefore can be free to slide in sliding slot, sliding rail dress
It sets in the unlocked state；Spring leaf enter sliding slot volume it is more when, then can not continue forward when slide block movement is at spring leaf
Movement, railroad are in the lock state.Therefore the railroad can be realized the locking and unlocking to sliding block, and the letter of its structure
Single, cost is relatively low.

Specific embodiment
The technical solution of the utility model is further elaborated with reference to the accompanying drawing.
It is referring to figure 1 and figure 2 a kind of railroad of door closer of the utility model, includes at least mounting base 1,
Sliding slot 11 is offered in mounting base 1, be provided with sliding block 2 with being slidably matched in sliding slot 11, and being provided in mounting base 1 can be with respect to it
The pushing block 3 of sliding, the railroad of door closer further include the spring leaf 4 of strip, and spring leaf 4 includes fixed section 41 and limit section
42, fixed section 41 is fixed in mounting base 1, and limit section 42 is partially disposed in sliding slot 11 and towards encircleing in sliding slot 11
It rises, limit section 42 is against on pushing block 3 far from the end of fixed section 41, and pushing block 3 and the spacing of fixed section 41 are bigger, then limit section 42
More enter in sliding slot 11.Therefore by the position of control pushing block 3, the depth that spring leaf 4 enters sliding slot 11, bullet can be changed
Reed 4 enter sliding slot 11 volume it is less when, then sliding block 2 can overcome spring leaf 4 elastic force, therefore can in sliding slot 11 from
By sliding, railroad is in the unlocked state (as shown in Figure 2)；Spring leaf 4 enter sliding slot 11 volume it is more when, then sliding block 2
It can not move forward when moving at spring leaf 4, railroad is in the lock state (as shown in Figure 1).Preferably
In embodiment, in the railroad of the door closer using the utility model, the position of door closer is adjusted, so that closing when door is in
When closed state, sliding block 2 is moved to the position of Fig. 1, and railroad is adjusted to lock state at this time, then door is kept in off position
It is locked.
The lug boss 21 extended towards spring leaf 4 is provided on sliding block 2, the end of lug boss 21 can be with spring leaf 4
Section 42 is limited to contradict, when limit section 42 is prominent more in sliding slot 11, limit 42 inner barrier sliding block 2 of section movement.In this implementation
In example, the end of lug boss 21 is the steel ball being embedded in sliding block 2, so that when unlocked, sliding block 2 passes through spring leaf
4 movements are more smooth, reduce the abrasion that spring leaf 4 is subject to.
The length extending direction of spring leaf 4 is parallel with the direction of motion of sliding block 2, is hurt and grinds by spring leaf 4 to avoid sliding block 2
Damage, while also simplifying structure.
The direction of motion of pushing block 3 is parallel with the length extending direction of spring leaf 4, one time preferably control spring leaf 4 limit
The projecting degree of position section 42.
Supporting walls 12 are provided in mounting base 1, supporting walls 12 are parallel with the direction of motion of pushing block 3, and pushing block 3 is far from spring leaf
4 one end is resisted against on supporting walls 12, and supporting walls 12 play the role of support and guiding to pushing block 3 simultaneously.
As a preferred embodiment, pushing block 3 includes the extending direction support portion vertical with 3 direction of motion of pushing block
31, the extending direction sliding part 32 parallel with 3 direction of motion of pushing block, the end of support portion 31 contradicts on spring leaf 4, for pair
Spring leaf 4 provides thrust, and sliding part 32 contradicts on supporting walls 12, and sliding part 32 and the contact area of supporting walls 12 are larger, have
Conducive to sliding.
Adjustment tank is arranged in being slidably matched in the adjustment tank 13 that mounting base 1 has extending direction parallel with sliding slot 11, pushing block 3
In 13, adjustment tank 13 constitutes supporting walls 12 far from the cell wall of spring leaf 4, therefore the structure of the railroad is more compact.
Electromagnet apparatus 5 is provided in mounting base 1, electromagnet apparatus 5 includes at least the electricity being fixed in mounting base 1
Magnet ontology 51, the push rod 52 for capableing of the movement of opposed electromagnets ontology 51, pushing block 3 are fixed on push rod 52.Electromagnet dress
Set 5 cost is more cheap, compact, be relatively suitably applied on the railroad.When door is in close state, electromagnet
Device 5 is powered, and push rod 52 pushes the limit section 42 of 3 driving spring piece 4 of pushing block towards protrusion in sliding slot 11, so that sliding block 2 is locked
Fixed, door remains off, and when needing to open the door, need to only power off to electromagnet apparatus 5, spring leaf 4 return back to limit section 42 from
It is partly extracted out in sliding slot 11, sliding block 2 is enabled to continue to slide in sliding slot 11.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
