Technical Field

The invention relates to the technical field of building hardware accessories, in particular to a damping-adjustable sliding block structure.

Background

The supporting block is also called a wind brace, is widely applied to casement doors and windows and is used for protecting window sashes from being damaged by wind power. The conventional wind bracing sliding block slides in the transmission notch of the door and window without effective sliding damping adjustment, so that the wind bracing cannot effectively protect the window sash or the door and window. In order to solve the above problems, it is necessary to provide a sliding damper on the spreader, however, the existing damper lacks an adjustable function.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a damping-adjustable sliding block structure which is novel and reliable in structure and can simply adjust the resistance of a damping block.

In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: the utility model provides an adjustable damped slider structure, includes unable adjustment base, grip block, regulation ejector pad and adjusting screw, the shaping of the unable adjustment base bottom left and right sides has the sand grip, grip block and regulation ejector pad all with unable adjustment base sliding fit, this grip block left and right sides shaping has the convex part simultaneously, convex part and sand grip cooperation centre gripping, grip block one side shaping has first wedge, simultaneously the regulation ejector pad shaping has the second wedge, first wedge is contradicted with the cooperation of second wedge, adjusting screw and unable adjustment base threaded connection drive the regulation ejector pad and contradict to the grip block.

The invention has the beneficial effects that: the accessible is twisted and is moved adjusting screw and drive the regulation ejector pad and push to the grip block, because first wedge face contradicts with the cooperation of second wedge face, consequently can drive the grip block downstream when adjusting the ejector pad and promoting the grip block to it is inseparabler to the centre gripping of section bar between convex part and the sand grip, make the damping piece increase to the sliding friction power of section bar, only need reverse twist when needs reduce the frictional force between damping piece and the section bar move adjusting screw can, can realize the damping quick adjustment through above-mentioned mode.

Preferably, a third wedge-shaped surface symmetrical to the first wedge-shaped surface is formed on the opposite side of the first wedge-shaped surface of the clamping block, and a fourth wedge-shaped surface matched and abutted with the third wedge-shaped surface is formed on the fixing base. Through the mutual cooperation of third wedge-shaped surface and fourth wedge-shaped surface, can further make the grip block descend under the push action of adjusting the ejector pad.

Preferably, a temperature-sensitive rubber block is arranged between the adjusting screw and the adjusting push block, and two sides of the temperature-sensitive rubber block are respectively abutted against the adjusting screw and the adjusting push block. When fire occurs, the temperature sensing rubber block is affected by temperature to melt, the melted temperature sensing rubber block does not abut against the adjusting screw and the adjusting push block, and the friction effect of the clamping block on the section bar disappears, so that the action of automatically closing the fire window or quickly closing the fire window by hands can be realized.

Preferably, the fixed base is formed with a first guide groove for guiding the sliding of the adjusting push block and a second guide groove for guiding the sliding of the clamping block. The first guide groove and the second guide groove can be used for respectively guiding and adjusting the push block and the clamping block to slide stably, and deviation and dislocation in the sliding process of the push block and the clamping block are avoided.

Preferably, the fixing device further comprises a fixing panel covering the fixing base.

Detailed Description

The claimed invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 5, the adjustable damper in this embodiment is connected to the sliding brace by a rivet and is also slidably connected to the notch of the profile.

The adjustable damping comprises a fixed base 1, a fixed panel 6 covering the fixed base 1, a clamping block 2, an adjusting push block 3, a temperature-sensitive rubber block 5 and an adjusting screw 4.

In this embodiment, the left and right sides of the bottom of the fixing base 1 are formed with protruding strips 11, and meanwhile, the fixing base 1 is formed with a first guide groove 13 for guiding the sliding of the adjusting push block 3 and a second guide groove 14 for guiding the sliding of the clamping block 2.

The left side and the right side of the clamping block 2 are provided with convex parts 21, and the convex parts 21 and the convex strips 11 are matched with the two sides of the notch of the clamping section bar. In the present embodiment, the clamping block 2 has a trapezoid structure, and a first wedge surface 22 and a third wedge surface 23 are formed symmetrically on the left and right sides of the clamping block 2. Meanwhile, the adjusting push block 3 is respectively formed with a second wedge-shaped surface 31, the fixing base 1 is formed with a fourth wedge-shaped surface 12, wherein the first wedge-shaped surface 22 is in fit interference with the second wedge-shaped surface 31, and the third wedge-shaped surface 23 is in fit interference with the fourth wedge-shaped surface 12.

Adjusting screw 4 and unable adjustment base 1 threaded connection, the block 5 is glued to the temperature sensing sets up between adjusting screw 4 and regulation ejector pad 3, and 5 both sides of block are glued to the temperature sensing respectively with adjusting screw 4 and regulation ejector pad 3 conflict.

The temperature-sensitive rubber block 5 can be driven to push the adjusting push block 3 to abut and push the clamping block 2 by screwing the adjusting screw 4. Because between first wedge-shaped surface 22 and the second wedge-shaped surface 31 and between third wedge-shaped surface 23 and the fourth wedge-shaped surface 12 the cooperation is contradicted, consequently can drive grip block 2 downstream when adjusting ejector pad 3 to grip block 2 promotion to it is inseparabler to the centre gripping of section bar between convex part 21 and the sand grip 11, make the sliding friction power of damping piece to the section bar increase, only need reverse twist adjusting screw 4 when needing to reduce the frictional force between damping piece and the section bar can, can realize the damping quick adjustment through above-mentioned mode.

Adjustable damping can use with the cooperation of fire prevention self-closing window in this embodiment, and the temperature sensing is glued the piece and is influenced by the temperature and melt when meeting fire, and the temperature sensing that melts is glued piece 5 and is no longer contradicted adjusting screw 4 and regulation ejector pad 3, and grip block 2 disappears to the friction effect of section bar to can realize the action that fire prevention window self-closing or staff closed fast.
