Description

Single slide rail door closer

Technical field

The utility model is relevant with door closer, is meant a kind of single slide rail door closer that allows applied door-plate adjust apace to be unlocked the location difficulty especially.

Background technology

A kind of positioner that is used for door as No. 398196 patent case announcement of European Announcement Number.Positioner is provided with a slide rail in a doorframe of door, and in slide rail, be provided with a slide block and a brake component, wherein slide block with the door a door-plate between utilize a cursor slide to be connected, and brake component includes a stator and a trimmer, and stator is fixed in the slide rail, and has a long slot bore, trimmer is installed in stator, and be positioned at the top of long slot bore, make the trimmer can displacement between the two ends of long slot bore, in order to adjust the difficulty that slide block combines with shell fragment.When door-plate was pushed open by external force, cursor slide can drive slide block and move along slide rail, and slide block is combined with shell fragment, in order to the location door-plate.

If will make the door-plate location that more easily is unlocked, the position of trimmer can be adjusted to the right-hand member of long slot bore, as if making door-plate be not easy the location that is unlocked, then the position of trimmer can be adjusted to the left end of long slot bore.Yet, in adjusting the process of trimmer, must be earlier the screw of stator be unclamped, again stator and trimmer are taken off from slide rail, then adjust the position of trimmer, after adjusting, in the slide rail of again stator and trimmer being packed into, packing screw at last.Just whole brake component to be disassembled just and can adjust, suitable inconvenience concerning general user, and, when stator puts in back in the slide rail, the position of stator may thus, will influence the adjusted effect of trimmer with adjusting preceding position deviation to some extent.

Summary of the invention

At the problems referred to above, main purpose of the present utility model is to provide a kind of single slide rail door closer, the difficulty that it can allow applied door-plate adjustment be unlocked and locate, and adjustment process is quite simple, can increase the convenience in the use.

For achieving the above object, the utility model by the following technical solutions: a kind of door closer, connect the door-plate that a doorframe and is hubbed at described doorframe, it includes: a holder, be installed in described doorframe, described holder has a slide rail; One brake unit, be located at the slide rail of described holder slippingly, described brake unit has a shell fragment, a forcing piece and a trimmer, and wherein said shell fragment has a detent and a long slot bore, and described forcing piece passes described long slot bore and is connected with described trimmer; One slide block is located at the slide rail of described holder slippingly, and combines with the detent of described shell fragment; One link arm connects described slide block and described door-plate respectively.

In the above-mentioned the technical solution of the utility model, described brake unit also has a stator, and described shell fragment is located at described stator.

Described stator has a dead bolt, and described dead bolt removably is installed in described holder.

Described holder has a plurality of fixing holes, described dead bolt selectively located therein one described fixing hole.

Adopt technique scheme, the utility model need only utilize and screw or unscrew forcing piece, can adjust the position of trimmer, and do not need whole brake unit is disassembled, make the utility model adjust the difficulty that slide block combines with detent according to the demand of different situations, adjusting the door-plate difficulty of location that is unlocked, and quite convenient when adjusting, can increase the convenience in the use.

The specific embodiment

In order to describe structure of the present utility model and characteristics in detail, existing following preferred embodiment of act and conjunction with figs. are described as follows.

As shown in Figure 1, be single slide rail door closer 10 of the utility model one preferred embodiment, it includes a holder 20, a brake unit 30, a slide block 40 and a link arm 50.

Holder 20 is installed in the doorframe 60, and as shown in Figure 2, holder 20 has the fixing hole 24 of a slide rail 22 and four preset distances of being separated by.

As Fig. 1, shown in Figure 3, brake unit 30 has a stator 32, a shell fragment 34, a forcing piece 36 and a trimmer 38.Stator 32 is installed in the slide rail 22, make the stator 32 can be along slide rail 22 left and right sides slippages, and stator 32 has a dead bolt 322, and dead bolt 322 can be locked in a wherein fixing hole 24 of holder 20, in order to stator 32 is fixed on a precalculated position of holder 20.One end of shell fragment 34 utilizes a screw 324 to be locked in the top of stator 32, and the bottom surface of the other end has an outstanding detent 342 downwards, and the central authorities of shell fragment 34 have a long slot bore 344.Forcing piece 36 from bottom to top passes long slot bore 344 and is connected with trimmer 38, make trimmer 38 be positioned at the top of shell fragment 34, and the restriction of the whole body portion 364 that can be by forcing piece 36 and displacement between the two ends of long slot bore 344, screw forcing piece 36, make a head 362 of forcing piece 36 be tight against shell fragment 34, trimmer 38 can be fixed.

Slide block 40 is installed in the slide rail 22 of holder 20, and can be along slide rail 22 left and right sides slippages.Slide block 40 has a draw-in groove 42.

One end of link arm 50 is locked in slide block 40, and the other end is locked in a door-plate 62 that is hubbed at doorframe 60.

Through adopting said structure, when door-plate 62 was opened by external force, link arm 50 can be subjected to the drive of door-plate 62 and interlock slide block 40 moves, make the detent 342 of slide block 40 extrusion elastic 40, snap in the draw-in groove 42 of slide block 40 (as shown in Figure 4) up to detent 342, thus, door-plate 62 is promptly finished the location.And when door-plate 62 cut out, link arm 50 meeting interlock slide blocks 40 made detent 342 disengagings (as shown in Figure 3) of draw-in groove 42 with the shell fragment 40 of slide block 40, to close door-plate 62.

If in the time of will adjusting the position of trimmer 38, with a screwdriver forcing piece 36 is changeed pine earlier, and the head 362 of mobile forcing piece 36, can be with moved further trimmer 38.When trimmer 38 moves to the right-hand member of long slot bore 344, forcing piece 36 is changeed tight.As shown in Figure 6, distance between the detent 342 of this moment and the head 362 of forcing piece 36 can be long, shell fragment 34 has an end of detent 342 can be more flexible, makes the detent 342 of shell fragment 34 than being easier to snap in the draw-in groove 42 of slide block 40, and just door-plate 62 is positioned than being easier to.If when trimmer 38 is moved to the left end of long slot bore 344, as shown in Figure 5, distance between the detent 342 of this moment and the head 362 of forcing piece 36 can be shorter, the end that shell fragment 34 has detent 342 does not just relatively have elasticity yet, make the detent 342 of shell fragment 34 relatively be not easy to snap in the draw-in groove 42 of slide block 40, door-plate 62 also just relatively is not easy to be positioned.

In addition, if will change the angle that door-plate 62 is opened, as long as unscrew dead bolt 322, and mobile brake unit 30 is locked in dead bolt 322 corresponding fixing hole 24 again to user's preposition, can change the angle that door-plate 62 is opened easily.

Thus, the utility model can be adjusted the position of trimmer according to different actual needs, allows door-plate can change the difficulty that it opens the location according to the demand of different situations, makes application door-plate of the present utility model have quite high use elasticity.And, in the process of adjusting, need only utilize a simple screwdriver can allow general user finish the action of adjustment, and not need whole brake unit is disassembled, can reach the purpose that increases ease of use.
