Description

Technical Field

[0001] This utility model relates to the field of office chairs, and in particular to an office chair that is easy to disassemble and assemble. Background Technology

[0002] An office chair is a type of seating specifically designed for office environments. It is typically used in conjunction with a desk to provide a comfortable posture and good support for people working, studying, or using a computer. Office chairs are designed with ergonomics in mind, aiming to reduce fatigue from prolonged sitting and improve work efficiency. However, with the needs of social development, such as changes in home and office spaces, people increasingly desire office chairs that are easier to disassemble and reassemble for transport, especially those that can be quickly disassembled and reassembled without the use of complex tools or specialized skills.

[0003] Existing office chairs have the following shortcomings: In the actual application of existing technology, the connection and fixation of various components of office chairs mostly rely on bolts. This structural design, which uses bolts as the main fixing method, has obvious limitations in disassembly and assembly operations. When it is necessary to disassemble, move, or replace parts of the chair, the operator must use special tools such as screwdrivers to loosen and remove the bolts one by one. Not only are the operation steps cumbersome and time-consuming, but when reassembling, the screw holes must be precisely aligned and the bolts tightened one by one. If the bolts are not installed properly, it may cause the chair structure to loosen, affecting the stability and safety of use. In addition, long-term repeated bolt disassembly and tightening operations can easily cause problems such as screw hole wear and bolt stripping, further reducing the service life and maintenance convenience of the chair. Utility Model Content

[0004] This invention provides an office chair that is easy to disassemble and assemble, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An office chair that is easy to disassemble and assemble includes a support mechanism, on the top of which a seat assembly is slidably connected. The support mechanism includes a support leg, on the outer wall of which a connecting plate is fixedly connected. A set of first connecting blocks is fixedly connected to the bottom of the connecting plate. A bidirectional lead screw is movably inserted into the outer wall of the first connecting block. A set of movable plates is threaded through the outer wall of the bidirectional lead screw. A set of inserts is fixedly connected to the outer wall of the movable plates. A set of second connecting blocks is fixedly connected to the bottom of the connecting plate. A guide rod is fixedly connected to the outer wall of the second connecting blocks. With the above components, disassembly and assembly can be completed without special tools, simplifying the operation steps and shortening the time consumption.

[0006] Preferably, a set of rubber pads is fixedly connected to the bottom of the support leg. The rubber pads fixed to the bottom of the support leg can increase the friction with the ground, improve the stability of the office chair when it is placed, and prevent the chair from shifting due to slight shaking during use. At the same time, the rubber material has a cushioning effect, which can reduce the noise generated when the chair moves or is subjected to force and comes into contact with the ground, thus reducing the interference with the office environment.

[0007] Preferably, the outer walls of the support legs are all fixedly connected with reinforcing blocks. The outer walls of the reinforcing blocks are fixedly connected to the bottom of the connecting plate. The reinforcing blocks between the outer walls of the support legs and the bottom of the connecting plate form a support structure, which enhances the stability of the connection between the support legs and the connecting plate, disperses the pressure transmitted from the seat assembly to the support mechanism, and avoids deformation or breakage at the connection due to long-term load.

[0008] Preferably, the top of the connecting plate has a through-hole, and the top of each support leg has a positioning groove. The through-hole provides a through channel for the connecting parts (such as fixing blocks) of the seat assembly and the support mechanism, which facilitates precise docking of the parts.

[0009] Preferably, a handle is fixedly connected to the front of the bidirectional lead screw, and the outer wall of the guide rod is slidably connected to the inner wall of the moving plate. The handle allows the user to directly rotate the bidirectional lead screw manually without the need for tools such as screwdrivers, further simplifying the disassembly and assembly operations and reducing the requirements for the user's operating skills.

[0010] Preferably, the seat assembly includes a seat, and a positioning block is fixedly connected to the bottom of the seat. A fixing block is fixedly connected to the bottom of the seat, and a slot is provided on the outer wall of the fixing block. The positioning block cooperates with the positioning groove on the top of the support leg to achieve quick and accurate positioning of the seat assembly and simplify the alignment steps during assembly.

[0011] Preferably, a seat cushion is fixedly connected to the top of the chair seat. The seat cushion can increase the comfort of the office chair and reduce fatigue caused by prolonged sitting through the elastic cushion, which is in line with ergonomic design.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. The support mechanism of this utility model achieves quick connection with the fixing block slot of the seat assembly through the coordinated cooperation of the bidirectional lead screw, the moving plate and the insert block: simply rotate the handle of the bidirectional lead screw to drive the insert block to insert or disengage from the slot, replacing the traditional bolt tightening method. It does not require special tools such as screwdrivers. Users can complete the disassembly and assembly manually. The operation steps are simpler and the time is significantly reduced. In particular, it reduces the operation difficulty for non-professional users and improves the ease of use. 2. In this utility model, the positioning groove at the top of the support leg fits into the positioning block at the bottom of the seat, ensuring accurate positioning of the seat assembly during installation and effectively preventing lateral displacement. At the same time, the guide rod and the moving plate are slidably connected, ensuring that the insert block moves smoothly along a straight line and achieves precise docking with the slot of the fixed block, avoiding structural loosening caused by misalignment. In addition, there is no need to repeatedly adjust the alignment of the screw holes during assembly, greatly improving the connection stability and significantly reducing the safety hazards caused by component displacement during use.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Please see Figures 1-4This utility model provides an office chair that is easy to disassemble and assemble, including a support mechanism 1, with a seat assembly 2 slidably connected to the top of the support mechanism 1; the support mechanism 1 includes a support leg 101, a connecting plate 103 is fixedly connected to the outer wall of the support leg 101, a set of first connecting blocks 108 is fixedly connected to the bottom of the connecting plate 103, a bidirectional lead screw 104 is movably inserted into the outer wall of the first connecting block 108, a set of movable plates 109 is threaded through the outer wall of the bidirectional lead screw 104, a set of insert blocks 110 is fixedly connected to the outer wall of the movable plate 109, a set of second connecting blocks 112 is fixedly connected to the bottom of the connecting plate 103, and a guide rod 111 is fixedly connected to the outer wall of the second connecting block 112. With the above components, disassembly and assembly can be completed without special tools, simplifying the operation steps and shortening the time.

[0018] like Figure 2 As shown, a set of rubber pads 102 are fixedly connected to the bottom of the support leg 101. The rubber pads 102 fixed to the bottom of the support leg 101 can increase the friction with the ground, improve the stability of the office chair when it is placed, and prevent the chair from shifting due to slight shaking during use. At the same time, the rubber material has a cushioning effect, which can reduce the noise generated when the chair moves or is subjected to force and comes into contact with the ground, thus reducing the interference to the office environment.

[0019] like Figure 2 As shown, the outer walls of the support legs 101 are all fixedly connected with reinforcing blocks 105. The outer walls of the reinforcing blocks 105 are fixedly connected to the bottom of the connecting plate 103. The reinforcing blocks 105 between the outer walls of the support legs 101 and the bottom of the connecting plate 103 form a support structure, which enhances the stability of the connection between the support legs 101 and the connecting plate 103, disperses the pressure transmitted from the seat assembly 2 to the support mechanism 1, and avoids deformation or breakage at the connection due to long-term load.

[0020] like Figure 2 As shown, the top of the connecting plate 103 is provided with a through-hole 107, and the top of the support leg 101 is provided with a positioning groove 106. The through-hole 107 provides a through channel for the connecting parts (such as the fixing block 204) of the seat assembly 2 and the support mechanism 1, so as to facilitate the precise docking of the parts.

[0021] like Figure 3 As shown, a handle 113 is fixedly connected to the front of the bidirectional lead screw 104. The outer wall of the guide rod 111 is slidably connected to the inner wall of the moving plate 109. The handle 113 allows the user to directly rotate the bidirectional lead screw 104 manually without the need for tools such as screwdrivers, further simplifying the disassembly and assembly operations and reducing the requirements for the user's operating skills.

[0022] like Figure 4As shown, the seat assembly 2 includes a seat 201, and a positioning block 203 is fixedly connected to the bottom of the seat 201. A fixing block 204 is fixedly connected to the bottom of the seat 201. A slot 205 is provided on the outer wall of the fixing block 204. The positioning block 203 cooperates with the positioning groove 106 on the top of the support leg 101 to achieve quick and accurate positioning of the seat assembly 2 and simplify the alignment steps during assembly.

[0023] like Figure 4 As shown, a seat cushion 202 is fixedly connected to the top of the seat 201. The seat cushion 202 can increase the comfort of the office chair. The elastic cushion 202 reduces the fatigue caused by sitting for a long time, which is in line with ergonomic design.

[0024] The usage and working principle of this device are as follows: During assembly, first align the bottom fixing block 204 of the seat assembly 201 with the through hole 107 at the top of the connecting plate 103 of the support mechanism 1. At the same time, ensure that the positioning block 203 at the bottom of the seat 201 is precisely embedded into the positioning groove 106 at the top of the support leg 101 to complete the initial positioning and prevent lateral displacement. Then, by rotating the handle 113 on the front of the bidirectional lead screw 104, the bidirectional lead screw 104 is driven to rotate. Since the thread on the outer wall of the bidirectional lead screw 104 passes through the moving plate 109, and the inner wall of the moving plate 109 is slidably connected to the guide rod 111 on the second connecting block 112, the moving plate 109 will move smoothly towards each other along the guide rod 111, thereby driving the insert block 110 on its outer wall to insert into the outer wall of the fixing block 204. In slot 205, a firm connection is achieved between the support mechanism 1 and the seat assembly 2. During disassembly, the handle 113 is rotated in the opposite direction, and the two-way lead screw 104 drives the moving plate 109 and the insert block 110 to move in the opposite direction, so that the insert block 110 disengages from the slot 205, and the seat assembly 2 can be removed from the support mechanism 1. Throughout the process, the reinforcing block 105 on the outer wall of the support leg 101 enhances the connection stability between the support leg 101 and the connecting plate 103 and distributes the load-bearing pressure. The rubber pad 102 at the bottom of the support leg 101 increases the friction, improves the overall stability, and reduces noise. The seat cushion 202 at the top of the seat 201 provides a comfortable sitting experience. Ultimately, the function of efficiently and stably disassembling and assembling the office chair without special tools is achieved.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
