Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to a seat assembly structure with telescopic armrests. Background Art

[0002] In outdoor or indoor environments, multiple groups of seats are usually set up. On the one hand, it increases the aesthetics, and on the other hand, it can be used for passing people to rest. The seat is composed of a seat surface, a backrest and armrests.

[0003] The armrest structure of the seat is usually directly welded and fixed on both sides of the seat surface, making it non-telescopic. Therefore, when a person with longer arms uses this armrest, the front section of the arm will be in a suspended state, resulting in a poor supporting effect of the armrest and inconvenient use. For this reason, we propose a seat assembly structure with telescopic armrests to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings of the existing technology involved in the background art, and to propose a seat assembly structure with telescopic armrests.

[0006] A seat assembly structure with telescopic armrests includes a seat frame body. Armrest frames are arranged on both sides of the seat frame body. The armrest frames are arranged in a U-shape. Extension rods are inserted at both ends of the armrest frames. A connecting rod is arranged at the end of the extension rod. A support rod is arranged at the opening at the end of the armrest frame. A handrest pad is arranged at the top of the connecting rod;

[0007] It can enable a person's hand to be placed above the handrest pad, increasing the comfort of placing the person's hand. At the same time, the connecting rod can be stretched and extended, so that people with different arm lengths can be supported, making the supporting effect better.

[0008] Preferably, a positioning rod is arranged at the end of the extension rod. A sliding groove is opened on the outer wall of the armrest frame. Both ends of the positioning rod pass through the sliding groove and are connected to the end of the extension rod;

[0009] It can limit the movement of the extension rod and avoid the situation that the extension rod moves too much and脱离 the inside of the armrest frame.

[0010] Preferably, a fixed insertion rod is inserted at the top of the armrest frame. A fixed insertion hole is opened at the top of the outer wall of the extension rod. The fixed insertion rod and the fixed insertion hole are mutually adapted;

[0011] After the extension rod is moved, the fixed embedded rod can be embedded into the fixed embedded hole for position fixing, so that the position of the hand rest pad can be adjusted and fixed, which is convenient for people to use.

[0012] Preferably, a support spring is sleeved on the outside of the fixed embedded rod, one end of the support spring is fixedly connected to the end of the fixed embedded rod, the other end of the fixed embedded rod is fixedly connected to the outer wall of the handrail frame, and one end of the fixed embedded rod extending into the fixed embedded hole is inclined;

[0013] When the connecting rod is pulled, the connecting rod drives the extension rod to move, so that the fixed embedding hole can squeeze the inclined surface of the fixed embedding rod, causing the fixed embedding rod to move, and then the fixed embedding rod is driven to restore through the supporting spring, so that the fixed embedding rod is embedded in the fixed embedding hole for limiting, thereby making it easier to pull out the connecting rod.

[0014] Preferably, a rotating rod is provided at the bottom end of the hand rest pad, a rotating block is provided at the bottom end of the rotating rod, the rotating rod and the rotating block both extend into the interior of the connecting rod, and the hand rest pad is rotatably connected to the connecting rod through the rotating rod and the rotating block;

[0015] The palm rest pad can be rotated at different angles so that support can be provided according to the habits of the user, thereby achieving a better support effect.

[0016] Preferably, a limit card block is provided at the bottom end of the rotating block, a limit card slot is provided inside the connecting rod, the limit card block and the limit card slot are adapted to each other, and the limit card slot and the limit card block are both hexagonal;

[0017] When a person's hand is placed above the hand rest pad, the arm applies gravity to the hand rest pad, so that the hand rest pad drives the limit card block to descend and embed into the inside of the limit card slot, thereby completing the limit fixation of the hand rest pad.

[0018] Preferably, a return spring is provided at the bottom end of the rotating block, a support bracket is provided at the bottom end of the return spring, the support bracket is annularly arranged, and the return spring and the support bracket are both sleeved on the outside of the limiting block;

[0019] When the arm leaves the palm rest pad, the return spring can support the rotating block, so that the rotating block drives the limit block to leave the limit slot. At this time, the palm rest pad can be adjusted in angle, making the adjustment and fixation of the palm rest pad more convenient.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. The utility model pulls the connecting rod, so that the connecting rod drives the extension rod to move, so that the extension rod drives the fixed embedding hole to contact the inclined surface of the fixed embedding rod, so that the fixed embedding rod moves, and then the fixed embedding rod is re-embedded into the fixed embedding hole through the action of the supporting spring for limited fixation, so that the support length of the handrail frame can be adjusted, which is convenient for people with different arm lengths to use.

[0022] 2. The utility model allows the person's hands to be placed above the hand rest pad, which increases the comfort of the person's hand placement.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Reference Figure 1-4A seat assembly structure with a telescopic armrest is shown. Armrest frames 2 are provided on both sides of the seat frame 1. The armrest frames 2 are in a U-shaped configuration. Then, extension rods 3 are inserted at both ends of the armrest frames 2, and a connecting rod 4 is provided at the end of the extension rod 3. At the same time, a support rod 6 is provided at the open end of the armrest frame 2, and a handrest pad 10 is provided at the top of the connecting rod 4. Then, a positioning rod 5 is provided at the end of the extension rod 3, and a chute is opened on the outer wall of the armrest frame 2. At the same time, both ends of the positioning rod 5 pass through the chute and are connected to the end of the extension rod 3. A fixed insertion rod 7 is inserted at the top of the armrest frame 2, and a fixed insertion hole 8 is opened at the top of the outer wall of the extension rod 3. Then, the fixed insertion rod 7 and the fixed insertion hole 8 are mutually adapted. At the same time, a support spring 9 is sleeved outside the fixed insertion rod 7, such that one end of the support spring 9 is fixedly connected to the end of the fixed insertion rod 7, and the other end of the fixed insertion rod 7 is fixedly connected to the outer wall of the armrest frame 2. Then, the end of the fixed insertion rod 7 extending into the fixed insertion hole 8 is inclined.

[0030] Specifically, the handrest pad 10 in this embodiment will be described. Please refer to Figure 4 , a rotating rod 11 is provided at the bottom end of the handrest pad 10. Then, a rotating block 12 is provided at the bottom end of the rotating rod 11. The rotating rod 11 and the rotating block 12 both extend into the connecting rod 4. At the same time, the handrest pad 10 is rotationally connected to the connecting rod 4 through the rotating rod 11 and the rotating block 12. A limit locking block 14 is provided at the bottom end of the rotating block 12, and a limit locking groove 13 is provided inside the connecting rod 4. Then, the limit locking block 14 and the limit locking groove 13 are mutually adapted. Both the limit locking groove 13 and the limit locking block 14 are hexagonal. At the same time, a return spring 15 is provided at the bottom end of the rotating block 12, and a support bracket 16 is provided at the bottom end of the return spring 15. The support bracket 16 is in a ring shape. The return spring 15 and the support bracket 16 are both sleeved outside the limit locking block 14.

[0031] Working principle: When the present utility model is in use, a person can directly pull the connecting rod 4, such that the connecting rod 4 drives the extension rod 3 to slide inside the armrest frame 2. At the same time, the extension rod 3 drives the fixed insertion hole 8 to squeeze the inclined surface of the fixed insertion rod 7. Then, the fixed insertion rod 7 moves along the inclined surface. When the position of the connecting rod 4 is adjusted, the support spring 9 drives the fixed insertion rod 7 to return to its original position, such that the fixed insertion rod 7 is inserted into the fixed insertion hole 8 for limit fixation, and the support length of the armrest frame 2 can be adjusted to facilitate arm support for people with different arm lengths.

[0032] The person's arm can be placed above the hand rest pad 10, and the hand rest pad 10 can be rotated and adjusted in angle, which is convenient for the person to adjust according to his or her own habits. After the adjustment is completed, the person's arm is placed above the hand rest pad 10 to apply pressure to the hand rest pad 10, causing the hand rest pad 10 to drop, thereby causing the rotating rod 11 and the rotating block 12 to drive the limiting card block 14 to be embedded in the limiting card slot 13, thereby limiting the angle of the hand rest pad 10, so that the hand rest pad 10 can better support the person. When the person's arm is out of the hand rest pad 10, the return spring 15 drives the rotating block 12 to recover, so that the rotating block 12 drives the limiting card block 14 to be out of the limiting card slot 13. At this time, the angle of the hand rest pad 10 can continue to be adjusted, making the use of the hand rest pad 10 more convenient.

[0033] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.
