Abstract
The utility model relates to a double-roller device, in particular to a double-roller device for clamping a shower screen door. The double-roller device comprises two rollers, a support arm, a clamping device and a roller shaft, the support arm is used for mounting the two rollers, the clamping device is used for clamping a door window, a balance point of the support arm is rotatably connected with one end of the roller shaft through a fastening part, the other end of the roller shaft is arranged in the clamping device, only can move up and down and cannot axially move, and an upper elastic device is arranged in the clamping device and is supported on the upper portion of the roller shaft. As the upper elastic device and a lower elastic device are arranged on the upper side or the lower side of the roller shaft, friction force between each roller and a sliding rail is reduced, the elastic devices can function in reducing vibration, and noise generated in pulling is low.
Description
Technical field
The utility model relates to a kind of Double-pulley device, relates in particular to the Double-pulley device that a kind of clamping shower screen door is used.
Background technology
The Double-pulley device that has clamping shower screen door to use comprises two pulleys, connects the support arm of two pulleys and the fixing clamping device used of the clamping shower screen door of support arm.During use, because slide rail sunset that is uneven is to be fixed on clamping device because of support arm, not two pulleys stressed, the same, easily wearing and tearing, application life is short: the friction of two pulleys and slide rail is larger, when pulling, can produce larger noise.
The utility model content
The utility model is to overcome the deficiencies in the prior art and provide a kind of two pulleys stressed evenly, long service life, and two pulleys are little with the slide rail friction, the little Double-pulley device of generation noise when pulling.
In order to achieve the above object, the utility model is achieved in that it is a kind of Double-pulley device, and it comprises two pulleys, and the support arm of two pulleys and the clamping device that the clamping door and window is used are installed, and also comprises a pulley spindle; The equalization point of support arm is rotationally connected by an end of securing member and pulley spindle, and the other end of pulley spindle is located in clamping device and only can moves up and down and can not axially-movable; Elastic device on being provided with in clamping device, upper elastic device be supported on pulley spindle above, the pulley spindle periphery is provided with lubrication oil.
Also be provided with lower elastic device in described clamping device, lower elastic device be supported on pulley spindle below.
Be positioned in described clamping device pulley spindle above be provided with the opening that Open Side Down, be provided with the upper slot that inserts in upper shed above pulley spindle, thereby the relative clamping device of pulley spindle only can be done move up and down and can not axially-movable; Upper elastic device is located in upper shed and upper slot and supports described pulley spindle.
Be positioned in described clamping device pulley spindle below be provided with the under shed of opening upwards, be provided with the lower slot that inserts under shed below pulley spindle, thereby the relative clamping device of pulley spindle only can be done move up and down and can not axially-movable; Thereby lower elastic device is located at and supports pulley spindle under shed and slot.
Described upper elastic device and lower elastic device are back-moving spring.
Be provided with the elasticity ditch between the clamping limb of described clamping device.
A kind of Double-pulley device of the utility model compared with prior art has following advantage:
1, because support arm and the pulley spindle that is located in clamping device are rotationally connected, two pulleys can ownly be adjusted stress, pulley stressed even, long service life;
2, owing to being provided with upper and lower elastic device in the upper of pulley spindle or lower both sides, reduced the friction between pulley and slide rail, also played the effect of vibration damping, the noise that produces when therefore pulling is little.
Description of drawings
Fig. 1 is perspective view of the present utility model.
The main TV structure schematic diagram that Fig. 2 is.
Fig. 3 is the cross-sectional view of Fig. 2 A-A of place.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model specific embodiment is described:
As Figure 1-3, as the preferred forms of a kind of Double-pulley device of the utility model, it comprises two pulleys 1, and the support arm 2 of two pulleys is installed, the clamping device 4 that the clamping door and window is used and pulley spindle 8, and they all form with plastic processing.The equalization point of support arm 2 is rotationally connected by securing member 6 end with pulley spindle, and the other end of pulley spindle is located in clamping device 4 and only can moves up and down and can not axially-movable, and securing member is bolt; Be provided with elasticity ditch 43 between the clamping limb of clamping device, clamping limb can be opened when the shower screen door is installed, the convenient installation.Elastic device 7 and lower elastic device 9 on being provided with in clamping device, upper elastic device be supported on pulley spindle above, lower elastic device be supported on pulley spindle below, the pulley spindle periphery is provided with lubrication oil.
In the present embodiment, the both sides up and down that are positioned at pulley spindle in clamping device 4 are respectively equipped with the upper shed 41 that Open Side Down and the under shed 42 that Open Side Down, be provided with upper end capping 3 above upper shed, be respectively equipped with the upper slot 81 in inserting upper shed on the both sides up and down of pulley spindle 8 and insert the lower slot 82 of under shed, thereby the relative clamping device of pulley spindle only can be done move up and down and can not axially-movable.Upper elastic device 7 is located in upper shed and upper slot, and lower elastic device 9 is located under shed and lower slot, thereby makes two elastic devices support pulley spindle.Upper elastic device 7 and lower elastic device 9 are back-moving spring.
During use, in sliding process, because the rotation of support arm 2 can be regulated the stressed of two pulleys 1 automatically, make the stressed even of two pulleys, improved the application life that produces.Moreover, because there is upper and lower elastic device the upper and lower both sides at pulley spindle 8, reduced the friction between pulley and slide rail, played the effect of vibration damping, the noise that produces when therefore pulling is little.
The above has done detailed description to the utility model preferred embodiment by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skills possess, can also make a variety of changes under the prerequisite that does not break away from the utility model aim.
Do not break away from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
