Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figure 1 to 11, the locking of the folding bed central controller of the present embodiment and tripper, comprise the connecting rod 4 connect that to be movably connected with central controller, described central controller comprises housing 1, cap 2, described cap 2 lid is placed on the end face of housing 1, and the bottom of cap 2 be placed in housing 1 and can be connected with the conjoined assembly that central controller moves up and down, described conjoined assembly and the connecting rod 4 stretched in housing 1 are movably connected and connect.This locking and tripper also comprise central controller, described central controller comprises housing 1, cap 2, described cap 2 lid is placed on the end face of housing 1, in the middle part of described housing 1 inner chamber, locating dowel 11 is vertically set, the top of locating dowel 11 is fixed with metal latch stator 12, the through hole 21 communicated up and down is provided with at the middle part of described cap 2, the clamping part 2a that can rotate is provided with in the bottom being positioned at cap 2, the top via through holes 21 of described clamping part 2a extend cap 2 and be placed in the pulling department that on cap 2 upper surface, stretchy cap 2 moves upward and be connected, clamping part 2a is provided with and clamping part 2a automatic rotary can be made to transfer the torsion spring 22 with metal latch stator 12 bottom surface phase buckle when clamping part 2a moves down, be provided with in the bottom of described clamping part 2a two can only be corresponding with metal latch stator 12 the button pin 23 of side 13 phase buckle.The bottom surface of described button pin 23 is respectively arranged with the oblique sliding limit 24 suitable with side 13, button pin on be respectively arranged with can with the buckling groove 25 of the corresponding side 13 phase buckle of metal latch stator 12, conflict respectively on side 13, slip into the subjacent of metal latch stator 12 in oblique sliding limit 24 when clamping part 2a moves down in clamping part 2a on two button pin 23, in described clamping part 2a, the buckling groove 25 of clamping part 2a is being snapped on the side 13 of metal latch stator 12 correspondence without automatically reversing under External Force Acting by torsion spring 22, when pulling department oppositely firmly reverses along torsion spring 22, the buckling groove 25 of clamping part 2a deviates from buckling state with the side 13 of sticking department 12, two button pin 23 of clamping part 2a move up and automatic unlocking together with cap 2.Described clamping part 2a is made up of buckle top 2c and buckle bottom 2b, described buckle bottom 2b is made up of relative two button pin 23 and top board 2e, described two button pin 23 and top board 2e are integrated the metal frame be made, and described top board 2e dismountable type is fixed on the bottom surface of buckle top 2c.Described torsion spring 22 is arranged in the container cavity 28 of buckle top 2c, and one end of described torsion spring 22 and the lug boss 26 of cap 2 bottom surface fix, and the holddown groove 27 on the other end of described torsion spring 22 and buckle top 2c fixes.Described clamping part 2a is provided with stopper slot 29, can contacts mutually with the side of lug boss 26 when a side of described stopper slot 29 is automatically torqued into extreme position in torsion spring 22 is without External Force Acting situation.
Pulling department comprises pull lever 31 and pulls button 32, described pull lever 31 two ends are stretched out to pull button 32 and can be arranged on rotationally and are pulled in button 32, described pull lever 31 two ends are provided with and prevent pull lever 31 from leaving the limiting section pulling button 32, described in pull button 32 to fix through the end face of through hole 21 with clamping part 2a.Described pull to smash reinforced sheet 33 is set, described reinforced sheet 33 can be arranged on pull lever 31 and pull between button 32 bottom surface with shirking, and by screw and clamping part 2a end face, pull and buckle 32 and be fixed together.Described limiting section is the pull handle 3 of being located at pull lever 31 two ends, and described pull handle 3 can be posted by gravity on cap 2 upper surface when not being subject to external tensile force.Described cap 2 upper surface is provided with rotation slot 20, described pull handle 3 can be arranged in rotation slot 20 rotationally, and when pull handle 3 is not when posting by external tensile force on the bottom surface of rotation slot 20, the upper level of described pull handle 3 is less than or equal to the height of cap 2 upper surface.Described cap 2 is fixed by the correspondence position of screw and conjoined assembly.
Operation principle: when clamping part moves down, oblique sliding limit contacts and relative movement mutually with the side of metal latch stator, clamping part slowly rotates, the torsion spring being now arranged in clamping part is in and stores power state gradually, until tiltedly sliding limit and side depart from, torsion spring drives clamping part to rotate backward, and buckle slot and the metal latch stator of clamping part are interlocked, and makes both closely lock together; Pull lever is added with pull handle, when needing to unlock, draws its pull handle and rotate, drive clamping part rotates, and the buckle slot of clamping part and sticking department side are departed from, and clamping part is mentioned smoothly, complete unlocking operation, the locking of this device unlocks and very rationally facilitates as can be seen here.
