[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1: A chair with round tube armrests, see Figure 1-Figure 10, including a round tube bracket 1, a first mounting rod 2, a second mounting rod 201, a fixed rod 3, a mounting frame 4, a support plate 5, a mounting sleeve 6, a support frame 7, a cushion 8 and a back cushion 801, the first mounting rod 2 is slidably provided on the rear sides of the two round tube brackets 1, and the second mounting rod 201 is slidably provided on the front sides of the two round tube brackets 1. The first mounting rod 2 and the second mounting rod 201 are jointly provided with a fixed rod 3 by welding, and the two fixed rods 3 are slidably provided with a mounting frame 4, and five support plates 5 are slidably provided on the mounting frame 4, the first mounting rod 2 is provided with two mounting sleeves 6, and the two mounting sleeves 6 are jointly provided with a support frame 7, the five support plates 5 are detachably provided with a cushion 8, and the support frame 7 is detachably provided with a back cushion 801, the left and right ends of the first mounting rod 2 are slidably provided with a first wedge block 10, and a first elastic member 9 is connected between the first wedge block 10 and the first mounting rod 2, and the round tube bracket A first pushing rod 12 is slidably provided on the rear side of the circular tube support 1, and a first extrusion block 11 is provided on the first pushing rod 12 by welding. The first pushing rod 12 is pushed so that the first extrusion block 11 can squeeze the first wedge block 10 to move backward. Second wedge blocks 14 are slidably provided on both ends of the second mounting rod 201. A second elastic member 13 is connected between the second wedge block 14 and the second mounting rod 201. A second pushing rod 16 is slidably provided on the front side of the circular tube support 1, and a second extrusion block 15 is provided on the second pushing rod 16 by welding. Five clamping blocks 401 are provided on the left and right sides of the mounting frame 4 by welding, and the clamping blocks 401 are clamped with the support plate 5. Two anti-skid pads 22 are provided at the bottom of the circular tube support 1. The anti-skid pads 22 increase the friction between the ground and the bottom of the circular tube support 1 to prevent the circular tube support 1 from moving. An anti-collision block 23 is provided on the rear side of the circular tube support 1 to prevent the circular tube support 1 from being hit and causing damage.

[0028] When the chair needs to be used, the first mounting rod 2 is inserted into the mounting groove of the round tube bracket 1, and the round tube bracket 1 squeezes the first wedge block 10 to move backward, and the first elastic member 9 is compressed accordingly. After the first mounting rod 2 is inserted, the first elastic member 9 returns to its original state to move the first wedge block 10 forward, so that the first wedge block 10 contacts the first squeezing block 11, and then the first wedge block 10 is limited, and the first mounting rod 2 is fixed on the round tube bracket 1. Repeat the above operation to fix the second mounting rod 201 on the round tube bracket 1, so that Instead of the traditional method of assembly and disassembly using bolts and mortise and tenon joints, the difficulty of disassembly and assembly is avoided when there are no assembly tools. The left and right sides of the mounting frame 4 are clamped on the fixing rod 3, and the support plate 5 is laid on the mounting frame 4 so that the support plate 5 is clamped with the clamping block 401. The support frame 7 is clamped on the two mounting sleeves 6, and the chair body is assembled, so as to facilitate loading and unloading and reduce packaging and transportation costs during transportation. The seat cushion 8 is then fixed on the support plate 5, and the back cushion 801 is fixed on the support frame 7, thereby completing the assembly of the entire chair.

[0029] Example 2: Based on Example 1, please refer to Figure 1 and Figure 5 The seat cushion 8 and the back cushion 801 are both covered with a PVC flame retardant leather cover 24, which has good flame retardancy and waterproof properties.

[0030] Before using the chair, first set the PVC flame retardant leather cover 24 on the seat cushion 8 and the back cushion 801, then fix the seat cushion 8 on the support plate 5, and fix the back cushion 801 on the support frame 7. When encountering an open flame, the PVC flame retardant leather cover 24 protects the seat cushion 8 and the back, thereby avoiding the safety hazard caused by ignition of the seat cushion 8 and the back.

[0031] See also Figure 8 , Fig. 9 and Fig.10 Two first Velcros 17 are connected to the support plate 5, a first Velcro 18 is connected to the bottom of the seat cushion 8, two fixing blocks 19 are provided on the support frame 7 by welding, a second Velcro 20 is connected to the fixing block 19, and a second Velcro 21 is connected to the rear side of the back cushion 801.

[0032] After using the chair for a long time, dust and other impurities will adhere to the seat cushion 8 and the back cushion 801. Pull the seat cushion 8 upward to disengage the first Velcro 17 and the first Velcro 18, and then pull the back cushion 801 forward to disengage the second Velcro 20 and the second Velcro 21, and then disassemble the seat cushion 8 and the backrest, so as to facilitate cleaning of the seat cushion 8 and the backrest. After cleaning, place the seat cushion 8 on the support plate 5 to make the first Velcro 17 and the first Velcro 18 stick together, and then fix the seat cushion 8 on the support plate 5. Repeat the above operations to fix the back cushion 801 on the support frame 7.
