Description
Technical field
The utility model relates to a kind of inhibiting device, and more particularly, it relates to a kind of limiting device.
Background technology
Hoist ceiling crane is the control handle for driving a vehicle usually, hoist ceiling crane inside can be provided with limiting device conventionally, limiting device plays a protective role in hoist ceiling crane inside, limiting device of the prior art has generally included top board and pedestal, between described top board and pedestal, be formed with U-shaped containing cavity, described top board dorsad containing cavity one side is provided with and external connecting portion, in containing cavity, be provided with stem stem, described stem stem arranges with connecting portion is concentric, on described stem stem, be relatively set with two banking stops, between two banking stops, be provided with limit spring, thereby the rotation of middle stem stem can drive two banking stop motion extruding limit spring, thereby realize protective effect.
Limiting device has very strict requirement for being assemblied in stem stem between top board and pedestal and the concentricity of connecting portion in fitting process, ensure that stem stem and the connecting portion concentricity between top board and pedestal is exactly service life and the limit effect that has ensured limiting device, concentricity for limiting device in prior art ensures by the fixed orifice working accuracy between top board and pedestal, when assembling, after being aimed at, fixed orifice on top board and pedestal is screwed into the location of realizing pedestal and top board after fastener, then in the assembling of carrying out connecting portion and stem stem, but only by the working accuracy of axis hole, and fastener between pedestal and top board still there will be between pedestal and top board play mutually, the limiting device having assembled under these circumstances can not be very desirable the requirement that reaches concentricity, affect to a certain extent the quality of product.
Utility model content
For the deficiency of prior art existence, when being to provide a kind of assembling, the purpose of this utility model can ensure the limiting device of concentricity, improve the outgoing of product.
For achieving the above object, the utility model provides following technical scheme: a kind of limiting device, comprise the pedestal and the top board that are fixedly connected with, described pedestal and top board are offered mounting hole at corresponding same position place, in described mounting hole, be provided with stop gear, the same position place that described pedestal and top board are corresponding offers knock hole.
By adopting technique scheme, described pedestal and top board are provided with knock hole on same position, when assembling, first will between pedestal and top board, use fastener to be fixed in corresponding position, in knock hole after preliminary fixing between pedestal and top board, insert the radius stay of a concentricity through overcorrection, further define the position between pedestal and top board, prevent from occurring between pedestal and top board the phenomenon of mutual play, then the assembling of carrying out stop gear just can improve the concentricity of limiting device, has improved the quality of product.
The utility model is further set to: the setting that is formed in one of the knock hole on described pedestal and top board.
By adopting technique scheme, the one-body molded concentric that can ensure the knock hole between pedestal and top board of knock hole on pedestal and top board, has further ensured the concentricity of the limiting device having assembled.
The utility model is further set to: described pedestal and top board are along being provided with two knock holees in same rectilinear direction.
By adopting technique scheme, the locating effect that is provided with two more single knock holees of knock hole is better, double shield locating effect, prevent in fitting process between pedestal and top board the situation of play mutually, improved the concentricity of limiting device.
The utility model is further set to: described top plate thickness is set to 1.5-2.5mm.
By adopting technique scheme; in prior art, the thickness of top board is traditionally arranged to be 1mm; in realizing limit function; top board usually can be hit; easily cause the modification of top board; top board is thickeied to 0.5-1mm, improved the intensity of top board, in use prevent that top board is because of the stressed situation that bends modification or occur fracture.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model limiting device embodiment.
Detailed description of the invention
With reference to Fig. 1, the utility model limiting device embodiment is described further.
A kind of limiting device, comprises the pedestal 1 and the top board 9 that are fixedly connected with, and described pedestal 1 and top board 9 are offered mounting hole 5 at corresponding same position place, in described mounting hole 5, are provided with stop gear, and the same position place of described pedestal 1 and top board 9 correspondences offers knock hole 8.
By adopting technique scheme, described pedestal 1 and top board 9 are provided with knock hole 8 on same position, when assembling, first will between pedestal 1 and top board 9, use fastener to be fixed in corresponding position, in knock hole 8 after preliminary fixing between pedestal 1 and top board 9, insert the radius stay 7 of a concentricity through overcorrection, further define the position between pedestal 1 and top board 9, prevent from occurring between pedestal 1 and top board 9 phenomenon of mutual play, then the assembling of carrying out stop gear just can improve the concentricity of limiting device, has improved the quality of product.
The setting that is formed in one of knock hole 8 on described pedestal 1 and top board 9.
By adopting technique scheme, the one-body molded concentric that can ensure the knock hole 8 between pedestal 1 and top board 9 of knock hole 8 on pedestal 1 and top board 9, has further ensured the concentricity of the limiting device having assembled.
Described pedestal 1 and top board 9 are along being provided with two knock holees 8 in same rectilinear direction.
By adopting technique scheme, the locating effect that is provided with two more single knock holees 8 of knock hole 8 is better, double shield locating effect, prevent in fitting process between pedestal 1 and top board 9 situation of play mutually, improved the concentricity of limiting device.
Described top board 9 thickness are set to 1.5-2.5mm.
By adopting technique scheme; in prior art, the thickness of top board 9 is traditionally arranged to be 1mm; in realizing limit function; top board 9 usually can be hit; easily cause the modification of top board 9; top board 9 is thickeied to 0.5-1mm, improved the intensity of top board 9, in use prevent that top board 9 is because of the stressed situation that bends modification or occur fracture.
The limiting device of prior art has generally included top board 9 and pedestal 1, between described top board 9 and pedestal 1, be formed with U-shaped containing cavity, described top board 9 dorsad containing cavity one side is provided with and external connecting portion 6, in containing cavity, be provided with stem stem 2, described stem stem 2 and the concentric setting of connecting portion 6, on described stem stem 2, be relatively set with two banking stops 3, between two banking stops 3, be provided with limit spring 4, thereby the rotation of middle stem stem 2 can drive two banking stops 3 to move pushes limit spring 4, thereby realize protective effect, be exactly connecting portion 6 and the stop gear of above mentioning specifically refers to, stem stem 2, the position limiting structure that banking stop 3 and limit spring 4 form.
The utility model specific implementation process:
In the time of assembling, first the fixed orifice of top board 9 and pedestal 1 is located mutually, then be screwed into bolt, tentatively by bolt tightening, then two knock holees 8 on pedestal 1 and top board 9 described in two groups of knock hole 8(can be along all directions setting, but in the direction setting and same straight line of arranging along fixed orifice for two knock holees 8 that ensure on the preferred described pedestal 1 of locating effect and top board 9) in insert respectively the radius stay 7 of concentricity through overcorrection, again bolt is further tightened fixing, finally carry out the assembling of stop gear, after completing the assembling of stop gear, two radius stays 7 are extracted.
