Detailed Description
To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.
The present invention will now be further described with reference to the accompanying drawings and detailed description.
Referring to fig. 1-6, the present embodiment provides an adjusting device including a sliding sleeve 11, a sliding member 12 and a catching member 13.
Specifically, the sliding sleeve 11 has a sliding cavity disposed along a length direction thereof and having at least one open end, the surface of the sliding sleeve 11 further has a plurality of bayonets 111 disposed along the length direction thereof at intervals, each of the bayonets 111 is communicated with the sliding cavity, and the sliding sleeve 11 further has a first seating surface 112 located at a front end of the bayonet 111 closest to the open end.
The slider 12 is mounted within the slide cavity and is able to slide within the slide cavity. The slider 12 includes a first slider plate 121 and a second slider plate 122. The first sliding plate 121 has a first end located in the sliding cavity and a second end located outside the sliding cavity, the first end of the first sliding plate 121 has an extension portion 1211 extending in a direction away from the second end, and the extension portion 1211 has a first protrusion 1212 protruding toward the bayonet 111. The first end of the first sliding plate 121 is further provided with a strip-shaped through slot 1213 extending in the sliding direction of the slider 12 in the sliding chamber.
The second sliding plate 122 is provided with a convex column 1221 and a second blocking surface 1222 at two opposite ends along the sliding direction of the sliding member 12 in the sliding cavity. The convex column 1221 is matched with the strip-shaped through groove 1213, the first end of the first sliding plate 121 is assembled on the second sliding plate 122, and the convex column 1221 is located in the strip-shaped through groove 1213, and the length of the strip-shaped through groove 1213 is greater than the diameter of the convex column 1221, so that the convex column 1221 can movably slide in the strip-shaped through groove 1213, so that the first sliding plate 121 and the second sliding plate 122 can relatively slide in a certain range; the second blocking surface 1222 is located on an end surface of the second sliding plate 122 facing the bayonet 111.
One end of the card element 13 is a pivot portion 131 pivoted to the first sliding plate 121, and the other end is a blocking portion 132 disposed in match with the bayonet 111, the blocking portion 132 has a guiding inclined surface 1321 disposed in match with the bayonet 111 and a blocking surface 1322 disposed in match with the bayonet 111, and a second protrusion 133 disposed opposite to the first protrusion 1212 is disposed on a side surface of the card element 13 away from the bayonet 111.
And an elastic member 14, wherein both ends of the elastic member 14 are respectively connected to the first projection 1212 and the second projection 133, and the elastic member 14 generates a force to the card member 13 to push the card member 13 to the bayonet. In the present embodiment, the elastic member 14 is taken as a spring for illustration.
Referring to fig. 4, when the adjusting device is installed on the folding lounge chair, one end of the sliding sleeve 11 is hinged on the front leg tube 21, and one end of the first sliding plate 121 extending out of the sliding sleeve 11 is hinged on the leg rest tube 22. When the footrests are adjusted upwards, the first sliding plate 121 is forced to move, the edges of the strip-shaped through grooves 1213 on the first sliding plate 121 are abutted to the protruding columns 1221 on the second sliding plate 122 to drive the second sliding plate 122 to move together, so as to drive the clamping piece 13 and the elastic piece 14 to move together, the guide inclined plane 1321 of the clamping piece 13 is forced to move downwards along the edge of the bayonet 111, meanwhile, the elastic piece 14 is squeezed to accumulate energy, and when the clamping part 132 of the clamping piece 13 is completely separated from the bayonet 111, the sliding piece 12 can be moved integrally; when the chair moves to the next bayonet 111, the clamping piece 13 is ejected and clamped into the bayonet 111 due to the elastic force of the elastic piece 14, and the blocking surface 1322 blocks the first sliding plate 121 from returning, so that the clamping function is realized, and the switching and clamping of different bayonets 111 can be repeatedly performed, and the leg rest tube can be adjusted at different angles in the actual use of the chair.
On the contrary, when the leg rest needs to be adjusted downward, the sliding member 12 is moved to the highest position, so that the locking portion 132 of the locking member 13 abuts against the first locking surface 112 on the sliding sleeve 11, and then is pressed downward, so that the other end of the strip-shaped through slot 1213 abuts against the protruding column 1221, and meanwhile, the first locking surface 112 provides a sufficient stroke distance to allow the locking portion 132 of the locking member 13 to be locked into the second locking surface 1222 on the second sliding plate 122, so as to prevent the locking portion 132 of the locking member 13 from being ejected by the elastic force of the elastic member 14, at this time, the sliding member 12 can be retracted into the sliding sleeve 11, thereby achieving downward adjustment of the leg rest.
In this embodiment, referring to fig. 2 and 3, the first sliding plate 121 has a circular recess 1214 formed on the first end, the circular recess 1214 has a fan-shaped notch 1215 formed toward the bottom of the sliding cavity, and the pivot portion 131 of the latch 13 is a circular piece matching with the circular recess 1214, the circular piece is installed in the circular recess 1214 and can swing in the fan-shaped notch 1215 of the circular recess 1214. Due to the arrangement, the clamping piece 13 and the first sliding plate 121 can be positioned on the same thickness, so that the width of the sliding cavity can be reduced, and the thickness of the sliding sleeve can be reduced; while the circular recess 1214 also acts as a stop for the catch 13.
In this embodiment, referring to fig. 4, a positioning block 113 is further disposed at the bottom of the sliding cavity, and when the first sliding plate 121 and the second sliding plate 122 move together to the bottom of the sliding cavity, the end of the second sliding plate 122 abuts against the positioning block 113, so as to prevent the whole sliding out of the sliding sleeve, thereby playing a role of protection.
Preferably, the end of the positioning block 113 facing the second sliding plate 122 has a recess 1131, and the end of the second sliding plate 122 facing the positioning block 113 has a protrusion 1223 matching with the recess 1131. When the first sliding plate 121 and the second sliding plate 122 move together to the bottom of the sliding cavity, the protruding portion 1223 can be snapped into the recessed portion 1131 for fixing, so that the sliding member 12 will not slide out due to gravity after the folding of the folding recliner chair.
It should be clear that, in the present embodiment, the adjustment device in the present embodiment is described by taking the adjustment of the angle of the leg rest as an example, but the adjustment device can be used for the adjustment of the head position angle as well.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
