Description

TECHNICAL FIELD

[0001] The utility model relates to a companion chair technical field, concretely relates to a safe companion chair. BACKGROUND

[0002] The companion chair is a folding type medical ward rest chair provided for patient family members, which can be sat or lain and folded to reduce space occupation, and can be used as a medical ward accompanying bed or as a widened sickbed to place medical devices and articles.

[0003] In the prior art, such as the Chinese patent with the announcement number CN212165391U and the name of safe companion chair, the technical scheme is recorded that the device is expanded and stored through the cooperation of the screw rod and the screw sleeve, so that the companion chair can be kept stable in any form, and the middle bed plate can be used as a backrest and the angle can be adjusted through the screw rod and the screw sleeve, thereby improving the applicability and comfort. However, no dining table is arranged in the ward, which is inconvenient for the accompanying personnel to have meals. UTILITY MODEL CONTENTS

[0004] The utility model provides a safe companion chair to solve the above problems.

[0005] The utility model adopts the following technical scheme: a safe companion chair, comprising a mounting frame, a rest mechanism and a dining mechanism; the rest mechanism is arranged on the mounting frame, and the rest mechanism is used for unfolding the companion chair to facilitate the rest of the accompanying personnel; the dining mechanism comprises a mounting rod, a lifting rod, a connecting rod, a table plate and an adjusting assembly; a storage bin is fixedly installed on one side of the mounting frame, the mounting rod is vertically arranged, the mounting rod is fixedly installed in the storage bin, the lifting rod is slidingly installed on the mounting rod, the connecting rod is hingedly connected to the upper end of the lifting rod, and the table plate is hingedly connected to the end of the connecting rod away from the lifting rod; a storage groove is formed in the upper end of the table plate; the adjusting assembly is arranged in the storage bin, and the adjusting assembly is used for adjusting the height of the table plate; when in use, the lifting rod is pulled upward to drive the table plate to rise, the connecting rod is rotated to make the table plate stand upward, and then the table plate is rotated to be horizontally placed; after the use of the table plate, the table plate is folded and stored in the storage bin.

[0006] Furthermore, the adjustment assembly includes an adjustment block and a first wedge block. Multiple adjustment holes are evenly distributed on the side wall of the storage compartment. The adjustment block is fixedly installed on the lower part of the side wall of the lifting rod. An adjustment groove is formed at the end of the adjustment block near the adjustment hole. The first wedge block is slidably installed in the adjustment groove. A spring is fixedly installed between the end of the first wedge block away from the adjustment hole and the adjustment groove. The adjustment assembly also includes an L-shaped plate and a slider. A sliding groove is formed on the inner wall of the storage compartment, located above the adjustment hole. Multiple reset holes are evenly distributed on the L-shaped plate, with the positions of the reset holes corresponding to the positions of the adjustment holes. The slider is fixedly installed at the end of the L-shaped plate near the sliding groove. The slider is located above the reset hole and is slidably connected to the slide groove. A spring is fixedly installed between the lower end of the slider and the slide groove. The L-shaped plate is slidably connected to the inner wall of the storage compartment. When the lifting rod is pulled up, the lifting rod drives the first wedge block to move upward through the adjusting block, so that the first wedge block passes through the reset hole and is inserted into the adjusting hole to limit the lifting rod. Thus, the height of the table can be adjusted by the lifting rod to adapt to the height required by the caregiver. After using the table, the L-shaped plate is pressed down, so that the L-shaped plate squeezes the first wedge block through the reset hole, so that the first wedge block is disengaged from the adjusting hole, releasing the limitation on the lifting rod, making it easy to store the table back into the storage compartment.

[0007] Furthermore, the resting mechanism includes a first bed board, a second bed board, a third bed board, and a support frame. The lower end of the first bed board is hinged to the mounting frame. The second bed board is hinged to the end of the first bed board away from the mounting frame. The third bed board is hinged to the end of the second bed board away from the first bed board. The support frame is fixedly installed at the lower end of the third bed board, and a shelf is fixedly installed on the support frame. A pull ring is fixedly installed on the hinged end of the first and second bed boards. A limit plate is fixedly installed on the mounting frame, and a limit hole is formed on the limit plate. A limit groove is formed at the lower end of the third bed board for limiting movement. A second wedge block is slidably installed in the groove, and a spring is fixedly installed between the upper end of the second wedge block and the limiting groove. When the device is used as a chair, the first and second bed boards are folded and vertically mounted on the mounting frame. The first bed board is horizontally mounted on the mounting frame and is engaged in the limiting hole by the second wedge block, so that the third bed board is limited on the mounting frame and kept stable. When the caregiver rests, the third bed board is pulled forward to unfold the second and first bed boards, so that the third, second, and first bed boards are placed on the same horizontal plane for the caregiver to rest.

[0008] The beneficial effects are: the companion chair is equipped with a table, which can be folded and stored in the storage compartment. The table can be unfolded and placed horizontally above the third bed board by means of the mounting rod, lifting rod and connecting rod, making it convenient for the caregiver to use;

[0009] The height of the lifting rod can be adjusted according to the needs of the caregiver by using the first wedge block and adjustment hole; the height of the table after unfolding can be adjusted by using the L-shaped plate to easily release the limit on the lifting rod, so that the table can be folded and stored in the storage compartment.
