Description

Technical Field

[0001] This utility model relates to the field of armrest technology, specifically to a seat armrest structure. Background Technology

[0002] There are various types of seats, such as vehicle seats. For rear passengers, the lack of armrests means there is no auxiliary support structure when the vehicle is bumpy. To address this, seat back armrest structures have been developed that can be optionally installed on the seats.

[0003] When assembling the seat armrests, both ends of the armrests are fixed to two sets of connecting rods between the seat and the headrest for rear passengers to hold onto. Currently, the backrest seat armrests are made of a rigid rod or a soft rope, which means that the overall grip length of the armrest is not adjustable, and it cannot provide sufficient grip space when there are many people in the back seat.

[0004] The armrest structure designed in this scheme allows for adjustment of the overall length of the armrest, thereby increasing the grip space when needed by extending the length of the armrest. Utility Model Content

[0005] (a) Technical issues The present invention aims to at least solve the problem of the non-adjustable lateral length of handrails in the prior art.

[0006] (II) Technical Content This solution provides a seat armrest structure, achieved through the following specific technical means, including: The rigid tube has two sets of protrusions welded and fixed to its front side. The protrusions also have mounting holes for connecting rods to pass through. The rigid tube is used as the handrail grip part. The extension tube comes in two sets, which can be pulled out from both ends of the rigid tube to serve as extended handle grips.

[0007] Preferred technical solution 1: An embedded block is fixed in the middle of the inner cavity of the rigid tube. The embedded block divides the inner cavity of the rigid tube into two sets of receiving cavities, left and right, and the two sets of extension tubes are respectively located in the two sets of receiving cavities.

[0008] Preferred technical solution 2: It also includes a rope, with a fixed embedded block passing through the middle of the rope and both ends passing through two sets of extension tubes respectively, and a movable handle connected between the two ends of the rope.

[0009] Preferred technical solution three: The movable handle is a split structure, that is, it is formed by detachable combination of handle one and handle two.

[0010] Preferred technical solution four: Both the first and second handles are fixedly connected to the end of the rope via protruding posts at the ends; Furthermore, the diameter of the protruding post is equal to the inner diameter of the extension tube, allowing handle one and handle two to be inserted into the corresponding extension tube port via the protruding post, thus achieving docking between the two.

[0011] Preferred technical solution five: There is a protrusion on the inner wall of the outer end of the rigid tube, which is used to block the outside of the protrusion end, thereby limiting the extension length of the extension tube.

[0012] Preferred technical solution six: The rigid pipe is also equipped with a garbage bag support frame, which is a U-shaped frame with collars fixed at both ends, and the collars are rotatably fitted onto both ends of the rigid pipe; The U-shaped garbage bag holder has rectangular frames protruding on both the left and right arms. When in use, the handle of the garbage bag is placed on the rectangular frame, and the rectangular frame is used to open the handle. Meanwhile, a protruding rod extends from the upper outer side of the rectangular frame near the rigid pipe. When the garbage bag is spread out and placed vertically, the protruding rod and the upper wall of the rectangular frame form a hook for directly hooking the garbage bag.

[0013] (III) Technical Effects The above structure gives this solution the following advantages: 1. The combination of extension tube and rigid tube allows for the addition or removal of gripping points in the lateral direction, thus providing more gripping points when needed; 2. The combination of rigid tubing and movable handles allows for switching between hard and soft handrails, enabling users to choose according to their personal preferences; 3. The structure of the garbage bag opening frame allows for the hooking and opening of garbage bags or other items in various situations. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example 1:

[0017] Please see Figures 1-5 The seat armrest structure includes a rigid tube 1 and an extension tube 2, wherein the rigid tube 1 and the extension tube 2 are metal tubes, wherein: Two sets of protrusions 11 are welded and fixed on the front side of the rigid tube 1. The distance between the two sets of protrusions 11 is adapted to the distance between the two sets of connecting rods on the headrest. The protrusions 11 are also provided with mounting holes 111 for the connecting rods to pass through to fix the rigid tube 1. The rigid tube 1 is used as the armrest grip part. The length of the rigid tube 1 does not exceed the width of the chair back. The extension tube 2 has two sets, which can be pulled out from both ends of the rigid tube 1 to be used as extended handles. When not in use, the extension tube 2 can be pushed back into the rigid tube 1 for storage. Specifically: An insert block 12 is fixed in the middle of the inner cavity of the rigid tube 1, and the insert block 12 divides the inner cavity of the rigid tube 1 into two sets of receiving cavities 13, one on the left and one on the right; the two sets of extension tubes 2 are respectively located in the two sets of receiving cavities 13. The inner wall of both the inner and outer ends of the receiving cavity 13 has internal threads 14. At the same time, the inner end of the extension tube 2 has a protruding end 21. The diameter of the protruding end 21 is larger than the diameter of the extension tube 2. The outer wall of the protruding end 21 has external threads 211, which are adapted to the internal threads 14. The external thread 211 intermittently engages with the two sets of internal threads 14 in the receiving cavity 13. When the extension tube 2 is pulled out to the outer end of the receiving cavity 13 from the protruding end 21, the extension tube 2 is screwed to engage the external thread 211 with the inner thread 14 at the outer end, thus fixing the extended state of the extension tube 2. There is a protrusion 15 on the inner wall of the outer end of the rigid tube 1. The protrusion 15 is located outside the inner thread 14 on the inner wall of the outer end of the rigid tube 1. When the external thread 211 of the extension tube 2 engages with the inner thread 14 at the outer end, the protruding end 21 contacts the protruding end 15. The extension tube 2 is blocked from moving outward by the protrusion 15, thus limiting the extension length of the extension tube 2. When moving the extension tube 2 back, first twist the extension tube 2 inward so that the external thread 211 disengages from the inner thread 14 at the outer end. Then push the extension tube 2 back to the protrusion 21 and the inner end of the receiving cavity 13. Then twist the extension tube 2 so that the external thread 211 engages with the inner thread 14 at the inner end, thus fixing the receiving state of the extension tube 2. At this time, a small part of the outer end of the extension tube 2 remains outside the rigid tube 1, which is convenient for gripping when moving the extension tube 2 outward next time. Example 2:

[0018] Based on Example 1 Please see Figures 1-4 The seat armrest structure also includes a rope 3, with the middle of the rope 3 passing through and fixed to the embedded block 12. Both ends of the rope 3 extend from two sets of extension tubes 2, and a movable handle 4 is connected between the two ends of the rope 3. Due to the connection of the rope 3, the movable handle 4 has a large range of motion when gripping. Specifically: The movable handle 4 is a split structure, consisting of handle one 41 and handle two 42. Handle one 41 and handle two 42 are respectively fixed to the end of the rope 3 through protruding posts fixed to their ends. Handle one 41 and handle two 42 can be combined and connected. Handle one 41 and handle two 42 can be connected by threads, such as the external thread 211 on handle one 41 engaging with the external thread 211 on handle two 42. When the extension tube 2 is stored in the storage cavity 13, the first handle 41 and the second handle 42 can be assembled as a handle; before the extension tube 2 needs to be extended for use, the first handle 41 and the second handle 42 need to be separated, at which time the rope 3 is stored in the extended extension tube 2. The diameter of the protruding post is equal to the inner diameter of the extension tube. The first handle 41 and the second handle 42 can be inserted into the corresponding extension tube port through the protruding post, so as to realize the connection between the first handle 41 and one set of extension tubes 2, and the second handle 42 and another set of extension tubes 2. Thus, when the extension tube 2 is extended, the connection between the first handle 41 and the second handle 42 and the two sets of extension tubes 2 can prevent the first handle 41 and the second handle 42 from hanging down and shaking randomly. The sum of the lengths of the rope 3 and the two sets of protruding posts is equal to the distance between the far ends of the two sets of extension tubes 2 when the protruding ends 21 and protrusions 15 on the two sets of extension tubes 2 are in contact. That is, at this time, the first handle 41 and the second handle 42 are connected to the two sets of extension tubes 2, and the rope 3 is in a taut state. By utilizing the limitation of the posture of the rope 3, the first handle 41 and the second handle 42 also become part of the extension tube 2, further increasing the lateral gripping space. Example 3:

[0019] Based on Example 1 or Example 2 Please see Figures 1-5 The seat armrest structure includes a garbage bag support frame 5 installed on the rigid tube 1. The garbage bag support frame 5 is a U-shaped frame with collars 53 fixed at both ends of the U-shaped frame, and the collars 53 are rotatably sleeved at both ends of the rigid tube 1. When not in use, place the garbage bag holder 5 vertically on the back of the chair. When in use, rotate the garbage bag holder 5 to a tilted or flat position, and then put the garbage bag on the garbage bag holder 5 to open it for use. The garbage bag holder has a U-shaped structure with both arms bent to form a raised rectangular frame 51. When in use, the handle of the garbage bag is placed on the rectangular frame 51, and the rectangular frame 51 is used to open the handle. Meanwhile, a protruding rod 52 extends outward from the upper end of the rectangular frame 51 near the rigid tube 1. When the garbage bag opening frame 5 is placed vertically, the protruding rod 52 and the upper wall of the rectangular frame 51 form a hook for directly hooking the garbage bag. At this time, it does not have the opening effect, but it occupies little space. A fixing ring 6 is fixedly sleeved on the rigid tube 1 near a set of collars, and multiple sets of insertion holes 61 are opened around the fixing ring 6. An insertion rod 7 slides through the side arm of the garbage bag support frame 5 near the fixing ring 6. When the insertion rod 7 is pushed into a set of insertion holes 61, the posture of the garbage bag support frame 5 can be fixed. When the posture of the garbage bag support frame 5 needs to be adjusted, the insertion rod 7 should be pulled out of the insertion hole 61 first, then the garbage bag support frame 5 should be rotated to a suitable angle, and then the insertion rod 7 should be reinserted into the corresponding insertion hole 61 to fix the garbage bag support frame 5 again.
