For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] like Figure 1 and Figure 2 As shown, an adjustable elbow support includes a support plate and a soft layer arranged above the support plate, and a cover plate can also be arranged below the support plate. The soft layer is made of soft material and can be an existing soft material such as a foam material or a leather layer. The soft layer is installed above the support plate, and the cover plate is installed under the support plate. The support plate includes an adjustment end 1 and a fixed end 2 arranged in sequence. The fixed end 2 is connected to a workbench such as a maintenance table, and the adjustment end 1 is located behind the fixed end 2. Figure 3 and Figure 4As shown, an insert strip 11 is provided in front of the adjustment end 1, and the insert strip 11 is inserted into the fixed end 2 and the position of the insert strip 11 in the fixed end 2 is controlled by an adjustment device. After the relative distance between the adjustment end and the fixed end is changed, the length of the elbow support is changed. The adjustment device can be an existing device, preferably the following device provided in this embodiment. A baffle 12 is provided at the rear of the adjustment end 1, and the baffle 12 is set at an angle A with the front of the adjustment end 1, and the angle A is preferably an obtuse angle. The baffle is set at an obtuse angle with the adjustment end so that the soft layer set above the baffle will not bend up too steeply, thereby only preventing the user's arm from falling back and reminding the user, and will not form too many restrictions on the user's arm.
[0030] like Figure 2 As shown, the soft layer includes an adjustable end soft layer 5 and a fixed end soft layer 6, and the adjustable end soft layer 5 also includes a raised tail end 52, and the raised tail end 52 is arranged above the baffle 12, and the angle between the raised tail end and the adjustable end soft layer is the same as the angle between the baffle and the front of the adjustable end. The surfaces of the adjustable end soft layer 5 and the fixed end soft layer 6 are both provided with arc grooves. The arc grooves are extended along the length direction of the adjustable end soft layer 5 and the fixed end soft layer 6, and the surface of the arc grooves is in an arc shape, which is used to place the user's arm. The surface of the adjustable end soft layer 5 is provided with a first arc groove 51, and the surface of the fixed end soft layer 6 is provided with a second arc groove 61, and the first arc groove 51 extends to the raised tail end 52. The raised tail end 52 is slightly tilted upward, so that the user will not fall off the elbow support even if the arm moves backward when working on the workbench, thereby improving the safety of use and the comfort during use.
[0031] like Figure 4 , Figure 7 and Figure 8As shown, the fixed end 2 is provided with a longitudinal slot 21 and a transverse slot 22 that cross each other. In this embodiment, the longitudinal slot 21 and the transverse slot 22 are preferably arranged vertically and the longitudinal slot is located below the transverse slot. The insert 11 is arranged in the transverse slot 22, and the adjustment device is arranged in the longitudinal slot 21. The adjustment device engages or disengages with the insert 11 to achieve the position adjustment of the adjustment end 1. After the adjustment device engages with the insert, the adjustment end is limited and fixed. When the adjustment device and the insert are disengaged from each other, the relative position of the adjustment end and the fixed end can be moved to adjust the length of the elbow support. After the adjustment is completed, the adjustment device is used to limit and fix. A limiting slot 23 is provided at the rear of the transverse slot 22, and limiting blocks 231 are provided at the openings on both sides of the limiting slot 23. The insert 11 is provided with a sawtooth structure on both sides in the middle, and protrusions 112 are provided on both sides of the top. The insert 11 extends from the transverse slot 22 to the limiting slot 23, the limiting block 231 is adapted to the protrusion 112, and the length adjustment range of the adjustment end is consistent with the moving stroke range of the insert, that is, the insert moves in the limiting slot. Figure 5 and Figure 6 shown.
[0032] like Figure 4 , Figure 6 and Figure 7 As shown, the adjustment device includes a button 3, a push rod 32 and a latch 33. The push rod 32 is installed in the longitudinal slot 21. One end of the push rod 32 is connected to the button 3, and the other end is provided with a latch 33. The button 3 is located outside the fixed end 2. The latch 33 is provided with a serration structure. The serration structure of the latch 33 is adapted to the serration structure of the insertion strip 11, and the serration structure at the top of the latch engages with the serration structures on both sides of the insertion strip. The longitudinal slot 21 is also provided with a first pressing block 31 and a second pressing block 35 at both ends. The first pressing block 31 and the second pressing block 35 are fixedly arranged on the fixed end 2 to limit the push rod 32 in the longitudinal slot 21. The first pressing block 31 and the second pressing block 35 are fixedly arranged above the push rod 32. A spring fixing device is provided on one side of the second pressing block 35, and the other end of the second return spring 34 is connected to the second pressing block 35. The longitudinal slot 21 is arranged perpendicular to the transverse slot 22 and is located below the transverse slot 22. The push rod 32 is located in the longitudinal slot 21. The latch 33 is located on the push rod 32 and is flush with the inserting strip 11. A second return spring 34 is arranged below the latch 33. A cover plate is arranged below the support plate to cover and limit the adjustment device, the transverse slot and the inserting strip.
[0033] When adjusting, the button 3 outside the fixed end 2 is pressed to push the push rod 32 inward and drive the latch 33 to disengage the insertion strip 11, thereby releasing the insertion strip 11 and moving the adjustment end 1 to adjust the length of the elbow. After releasing the button 3, the second pressing block 35 is bounced upward by the second return spring 34 below, and the latch 33 and the insertion strip 11 are meshed with each other again, so as to limit the adjustment end 1.
[0034] like Figure 4 and Figure 6 As shown, the inserting strip 11 is further provided with an open slot 111, which is arranged along the length direction of the inserting strip, and a first return spring 4 is arranged in the open slot 111, one end of the first return spring 4 is connected to the fixed end 1, and the other end is connected to the top end of the inserting strip 11. The first return spring also plays a return role after the adjustment end moves.
[0035] The adjustable elbow support of the utility model is provided with an arc-shaped groove adapted to ergonomics on the surface of the elbow support along the length direction of the elbow support, and a tilted tail end is provided at the rear of the elbow support. When in use, the arm can be placed in the arc-shaped groove of the elbow support, thereby increasing the comfort of use. When the user's arm moves backward, the tilted tail end can prevent the user's arm from falling and serve as a reminder. The support plate portion of the elbow support includes a fixed end and an adjustment end, the fixed end is connected to the workbench, and the adjustment end is provided at the rear of the fixed end. The length of the elbow support is adjusted by engaging or disengaging the adjustment device with the insert strip in front of the adjustment end and changing the position of the adjustment end.
[0036] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
