Description

Folding table structure

Technical Field

The utility model relates to the technical field of furniture, in particular to a folding table structure.

Background

Because of its foldable nature, folding tables take up little space in the folded state, are easy to store, and especially are favored by users with outdoor use requirements. There are various types of folding tables, such as a folding table in which a table top and a table frame are separately formed, and the two tables are separated from each other, and the table top is supported by overlapping two cross bars on the table frame during installation (the cross bars are generally disposed along the long axis direction of the table frame).

For example, chinese patent No. 202121903491.2 discloses a folding square table support structure, which includes a folding table frame, connecting members and supporting rods, wherein in the unfolded state of the folding table frame, the middle parts of two long sides of the upper surface of the folding table frame are respectively provided with a connecting member, the number of the supporting rods is four, one end parts of the supporting rods are pivotally connected and matched with the long side end parts of the upper surface of the folding table frame, and the other end parts of the supporting rods are movably matched with the connecting members. When the folding square table or the folding square table of the type (the folding table with the application numbers 202021271182.3 and 202121904643.0 can be referred to again) is folded, the outer end of the supporting rod needs to be folded outwards on the pivoting piece and then folded downwards (because the supporting rod is positioned right above the folding rod and can only be folded outwards when the supporting rod is folded), the folding square table is folded from bottom to top and from outside to inside and then supported when the folding table is unfolded, and the supporting rod needs to be folded outwards to a large extent at two sides of the support in the folding and unfolding processes of the table frame, so that a large folding space is needed, the operation is inconvenient, and if the tent is small in inner space, the operation is difficult.

In order to solve the above problems, the applicant has developed and designed a novel folding table, and particularly please refer to an improvement of the folding table structure of chinese patent application No. 202220785420.5. However, in use of the folding table of applicant, as shown in fig. 1 and 2, the two legs 11' of the longitudinal sides of the table frame are connected by at least two foldable cross-strut sets 3', each cross-strut set 3 comprising two inclined struts 31' pivotally connected at the middle, the upper connection point of the two cross-strut sets 3' located above in the intersecting connection being provided with a support 5'. The supporting member 5 'is provided with a clamping groove 51' capable of supporting the cross rod 4', and the bottom surface of the supporting member 5' is also provided with two limiting grooves 52 'for limiting the upper ends of the inclined supporting rods 31', as shown in fig. 2.

With such a folding table structure, the inner ends of the cross struts 41' are directly supported in the clamping grooves 51' of the supporting members 5', the inner ends of the cross struts 41' are simply inserted into the clamping grooves 51', and when the cross struts 41 are carelessly lifted or pushed, the inner ends of the cross struts 41 are easily released from the clamping grooves 51', the cross struts 4' cannot be fixedly supported, and the table top cannot be kept stable. When the table frame is used, the transverse rod 4' or the cross support rod group 3' which is held by hands on the longitudinal side is generally pulled outwards when the table frame needs to be moved, and the inner ends of the transverse support rods 41' are also easily separated from the clamping grooves 51' directly when the transverse rod 4' is pulled. Moreover, the cross strut group 3' is easy to deform in the moving process, so that the position of the supporting piece 5' is changed, the middle part of the cross rod 4' is easy to break away from the supporting piece 5', and the table plate 2' is inclined or sunk due to the unbalance.

In addition, when the table board 1 'is just supported between the two cross bars 4', when the cross bar group 3 'on one side moves outwards, and the cross bars 4' on the other side also move outwards, the distance between the two cross bars 4 'can change, one cross bar 4' expands outwards, one side of the table board 2 'can lose support, so that the table board 2' can collapse downwards or fall down, and a lot of trouble is added to outdoor work. Furthermore, when the table plate 2' is arranged above the two cross bars 4', in order to ensure the stability of the table plate during use, the table plate 2' needs to be fixed during installation, the installation and matching structure in the existing structure is complex, such as the form of sleeving or clamping structure arranged at the bottom of the table plate, some table plates which are not suitable for rolling are still positioned unstably during use, and the problem that the table plate is easy to fall off from the cross bars during movement of the table frame is also easily caused.

In view of the above, the present inventors have developed and designed the present utility model by continuously and intensively conceived many defects and inconveniences caused by the imperfect structural design of the folding table, and actively researching and improving the trial work.
