Description

Technical Field

[0001] The utility model relates to the field of seats, in particular to a seat which is easy to assemble. Background Art

[0002] The seats of existing seats on the market all have the function of sliding forward and backward adjustment. For example, a learning seat for children can slide the seat forward and backward and adjust the seat depth to be suitable for children of different ages and developmental states.

[0003] For example, in the patent for a children's chair with announcement number CN2187817, the lower end of the seat is supported by a seat support rod connected between two front height adjustment rods. In order to ensure the connection strength, front and rear adjustment rods are welded to the seat support rods, and the bottom end of the seat is connected to the front and rear adjustment rods so that the seat can slide back and forth and adjust the seat depth, but the seat still has defects.

[0004] In order to ensure that the bottom end of the seat can be placed on the front and rear adjustment rod and slide back and forth stably, a corresponding limiting component must be connected between the seat and the front and rear adjustment rod to prevent the seat from moving longitudinally when sliding back and forth. This limiting component is usually installed inside the seat to keep the seat stable when sliding; if the seat is installed on the front and rear adjustment rod and the limiting component is installed before the seat leaves the factory, the packaging volume of the seat will be too large, which will be inconvenient to transport and will lead to corresponding increased transportation costs; if the seat and other components are packaged and transported separately, it will be difficult for the user to install the limiting component inside the seat, which will affect the user experience of the seat. Summary of the invention

[0005] In order to solve the above-mentioned technical problems, the purpose of the utility model is to provide a seat that is easy to assemble.

DETAILED DESCRIPTION

[0034] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0035] In the following description, many specific details are set forth to facilitate 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 protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0036] The specific implementation of the utility model is as follows:

[0037] like Figure 1-8 As shown, the utility model provides a seat that is easy to assemble, comprising:

[0038] The seat 2 has a sliding portion 22 hanging down on both the left and right sides of the seat 2, and a slide groove 21 extending forward and backward is provided on the sliding portion 22; the slide groove 21 penetrates the sliding portion 22 in the left and right directions;

[0039] The support member 33 is symmetrically connected to the left and right sides of the seat 2, and the support member 33 is inserted into the corresponding slide groove 21. The support member 33 is provided with an avoidance hole 35 for connecting the left and right sides of the support member 33; and the outer side of the support member 33 is provided with a limit portion 34 protruding outward, and the limit portion 34 abuts against the outer side of the sliding portion 22;

[0040] The connecting assembly 5 includes a cap screw 51 and an internal threaded tube 53. The cap screw 51 is usually a locking bolt or a screw. The internal threaded tube 53 passes through the avoidance hole 35 from the inner side of the sliding part 22, and a limiting cap 54 is provided at one end of the internal threaded tube 53 on the inner side of the sliding part 22. The limiting cap 54 abuts against the inner side of the sliding part 22.

[0041] The cap screw member 51 is threadedly connected to the internal threaded tube 53 from the outside of the support member 33 , so that the sliding part 22 is always located between the limiting part 34 and the limiting cap 54 when sliding forward and backward.

[0042] Further, if Figure 3-6 As shown, the capped threaded member 51 includes a screw and a handle 52 that is arranged on the head of the screw for easy rotation. The head of the screw has a cap body (not shown in the figure). The cap body is fixedly connected to the handle 52; the handle 52 can facilitate manual assembly of the seat 2 and the support member 33; the assembled seat has a sliding state and a locking state; the handle 52 is rotated in one direction to clamp the sliding part 22 between the limiting part 34 and the limiting cap 54, and the seat is in a locked state at this time; the handle 52 is rotated in the opposite direction to loosen the capped threaded member 51 and the internal threaded tube 53, so that the seat is switched to a sliding state; after assembly, the seat 2 can also be adjusted by rotating the handle 52 to slide forward and backward and lock. The design is simple and ingenious, and it kills two birds with one stone.

[0043] Furthermore, in order to provide the seat 2 with stable support and prevent the occupant from tipping over or rocking back and forth on the seat 2 when sitting, the support member 33 should have sufficient contact with the slide groove 21, so the ratio of the front-to-back length of the support member 33 to the front-to-back length of the slide groove 21 is 1:4-1:2; and the support member 33 is a strip-shaped body, and the length range of the support member 33 is 100mm-150mm; the reasonable shape and length range of the support member 33 make the sliding connection of the seat 2 more stable.

[0044] Furthermore, in order to prevent the internal threaded tube 53 inserted from the inner side of the sliding portion 22 of the seat 2 from rotating circumferentially and to ensure that the threaded member with a cap 51 can be normally locked or loosened, a limiting rib 55 is integrally formed on the outer wall of the internal threaded tube 53, and a groove 36 is preset on the hole wall of the avoidance hole 35. The limiting rib 55 is located in the groove 36 to limit the circumferential rotation of the internal threaded tube 53 along its own axis; thereby, the internal threaded tube 53 can be tightened or loosened when the threaded member with a cap 51 rotates forward or reversely.

[0045] Furthermore, in order to form longitudinal support for the seat 2, the bottom end of the seat 2 is provided with chair legs 1 symmetrically arranged on the left and right sides of the seat 2, and the support member 33 extends downward and forms an extension portion 32, and the terminal position of the extension portion 32 has a connecting portion 31, and the connecting portion 31 is connected to the chair leg 1; and the connecting portion 31, the extension portion 32, and the support member 33 are integrally formed components; the integrally formed structure has high connection strength and is also convenient for assembly with the seat 2.

[0046] Furthermore, the connecting portion 31 is a sleeve, and the connecting portion 31 and the chair leg 1 are configured to be slidably connected; the chair leg 1 has a plurality of gear holes 11 evenly distributed along its length direction, and a control component is connected to the connecting portion 31, and the control component includes a clamping column 101 that is plugged into and matched with the gear hole 11, and the clamping column 101 is controlled to be inserted into or out of the gear hole 11 so that the connecting portion 31 can be fixed or slidably adjusted relative to the chair leg 1; so that the seat 2 can stay stably in the corresponding position after longitudinal lifting and lowering adjustment; thereby enriching the function of the seat, so that the seat 2 can be adjusted and positioned accordingly in both the horizontal and vertical directions.

[0047] Further, if Figure 7 As shown, in order to make the control component easier and more labor-saving to operate, the control component includes a blocking member and an elastic member 9 acting on the blocking member, and the blocking member includes a control part 10 connected to the clamping column 101; the control component has a locked state and an unlocked state. When the control component is in the locked state, the clamping column 101 is clamped into one of the gear holes 11 on the chair leg 1; when the control component is switched to the unlocked state, the control part 10 can make the clamping column 101 disengage from the gear hole 11 under the action of external force, and cause the elastic member 9 to deform, and at this time the connecting part 31 can slide in the length direction of the chair leg 1; when the external force is removed, the elastic member 9 is reset and generates elastic force, and the blocking member drives the clamping column 101 to be clamped into the corresponding gear hole 11 under the action of the elastic force, and at this time the control component switches back to the locked state.

[0048] Further, if Figure 8 As shown, the integrally formed connecting portion 31, the extending portion 32, and the supporting member 33 can be regarded as an integral adjusting member 3. In order to enable the adjusting members 3 on the left and right sides of the seat 2 to slide synchronously, a cross bar 4 is connected between the two adjusting members 3 on the left and right sides of the seat 2; the extending portion 32 is provided with a preset hole 37 that passes through the left and right sides, and the end of the cross bar 4 is preset with a corresponding screw hole 41, and the connecting screw 12 passes through the preset hole 37 and is screwed into the screw hole 41 to connect the end of the cross bar 4 to the adjusting member 3.

[0049] Furthermore, the inner side of the extension portion 32 has a horizontal plate a extending toward the seat 2, and a clamping area b is formed between the horizontal plate a and the strip-shaped support member 33. The slide groove 21 extends forward and backward on the sliding portion 22 of the seat 2 and divides the sliding portion 22 into an upper portion and a lower portion. In order to avoid cracking of the lower portion of the sliding portion 22, that is, the lower edge of the sliding portion 22, the lower portion is in the clamping area b, thereby sharing the supporting force of the support member 33 on the seat 2.

[0050] Furthermore, the cross bar 4 rests against the lower end of the cross board a to provide support for the cross board a, so that the cross board a can transfer the support force of the seat 2 to the cross bar 4, thereby avoiding deformation or cracking caused by excessive force on the cross board a when sharing the support force.

[0051] Furthermore, a ring-shaped protruding periphery is provided at a corresponding position of the outer wall of the sleeve, and the clamping column 101 passes through the tube wall of the sleeve inside the periphery and is clamped into the clamping hole 11; a column is provided on the outer wall of the sleeve inside the periphery, and a screw hole 38 is preset on the column. The control part 10 is a shell structure with a hollow outer side, and a corresponding avoidance area is provided on the control part 10, and the control part 10 is sleeved on the column, and the elastic member 9 is a compression spring sleeved on the column, and a limiting screw 8 is matched in the screw hole 38 on the column, and the limiting screw 8 is against the compression spring; when operating the control part 10, pulling the control part 10 can compress the compression spring and generate elastic force, so that the clamping column 101 escapes from the gear hole 11, and then the connecting part 31 and the seat 2 slide longitudinally; after releasing the control part 10, the compression spring resets and releases the elastic force, so that the clamping column 101 is clamped into the corresponding gear hole 11 to limit the up and down movement of the seat 2 after sliding into place.

[0052] Furthermore, a protective cover 7 is connected to the outside of the control unit 10 , and the protective cover 7 can block the outside of the control unit 10 to prevent debris from entering the control unit 10 .

[0053] Furthermore, a bushing 6 is connected inside the sleeve to separate the chair leg 1 and the sleeve; the bushing 6 is clamped with the sleeve; an elastic buckle 61 is provided on the bushing 6, and a bayonet 39 is provided on the sleeve. The elastic buckle 61 is clamped in the bayonet 39, thereby sliding synchronously with the sleeve and separating the chair leg 1 from the sleeve to prevent excessive wear of the sleeve and the chair leg 1.

[0054] Furthermore, a corresponding avoidance cavity 62 is provided on the bushing 6 , and the avoidance cavity 63 can provide an avoidance space for the clamping column 101 , so that the clamping column 101 can be smoothly clamped into the gear hole 11 .

[0055] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
