Bed body extending mechanism

Abstract

The utility model belongs to the field of medical instruments, and provides a bed body extending mechanism which comprises a bed frame. The extending mechanism is slidably arranged in the bed frame and used for extending the using length of the bed frame; the limiting mechanism is arranged at the bottom of the bed frame and used for limiting and fixing the extension mechanism; the sliding mechanism is fixedly arranged on the inner wall of the bed frame and assists the extension mechanism in sliding use; the supporting mechanism is arranged outside the bed frame; due to the fact that the bed leg transverse supports are connected to one side of the bed frame in the sliding mode through the two extending inner frames, after the feet and legs of a patient are subjected to an operation, when the using length of the bed frame needs to be prolonged, the two extending inner frames can be pulled out of the interior of the bed frame and are limited and fixed through matching of the pin shafts and the front holes, and therefore the using length of the whole bed frame is increased; a patient can adjust and use conveniently.

[0002] Medical beds, also known as medical beds or treatment beds, are furniture used in medical institutions (such as hospitals, clinics, nursing homes, etc.) for patients to lie down during diagnosis, treatment, nursing or rehabilitation. These beds are usually designed to be more versatile than ordinary household beds to meet the special needs of patients during medical treatment.

[0003] However, the bed length of a standard medical bed is suitable for a human body of less than 185cm in height. In actual use, the following situation may occasionally occur: after foot and leg surgery for some patients, the total length of the body plus the rehabilitation materials will be much longer than 185cm, and the patient will not be able to use the medical bed normally. In addition, the length of the medical bed is fixed and difficult to adjust, causing inconvenience to the patient.

[0004] Therefore, those skilled in the art have proposed a bed extension mechanism to solve the problems raised by the background art. Utility Model Content

[0007] Preferably, the extension mechanism comprises two extension inner frames slidably arranged on one side of the bed frame, a bed foot cross brace is fixedly arranged between the two extension inner frames; two rollers are rotatably arranged on one end of the two extension inner frames away from the bed foot cross brace.

[0008] Preferably, the limiting mechanism includes a rear hole and a front hole opened at the bottom of the extended inner frame; a pin sleeve is fixedly provided at the bottom of the bed frame, a pin is elastically and slidably provided in the pin sleeve, a wrench is rotatably provided on the outer wall of the pin sleeve, and the pin and the wrench are connected; a positioning pin is fixedly provided at the top of the extended inner frame.

[0009] Preferably, the sliding mechanism comprises a sliding sleeve fixedly arranged on the inner wall of the extended inner frame, the outer wall of the sliding sleeve is integrally formed with an outer connecting wall, and the inner wall of the sliding sleeve is integrally formed with an inner connecting hole.

[0010] Preferably, the support mechanism includes a support base rotatably arranged at the bottom of the bed frame; a headboard is fixedly arranged at one end of the bed frame, and a head plate is arranged on the headboard; the extended inner frame is fixedly provided with a footboard through a cross brace at the foot of the bed, and a foot plate is arranged on the footboard.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, by arranging two extended inner frames on one side of the bed frame and slidingly connecting a cross brace at the foot of the bed, when the use length of the bed frame needs to be extended after the patient's foot and leg surgery, the two extended inner frames can be pulled out from the inside of the bed frame and limited and fixed through the pin shaft cooperating with the front hole, so as to increase the overall use length of the bed frame and facilitate the patient to adjust and use.

[0024] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] As attached Figure 1 To Attachment Figure 9 As shown:

[0026] The utility model provides a bed extension mechanism, comprising: a bed frame 1; an extension mechanism, which is slidably arranged inside the bed frame 1 and is used to extend the use length of the bed frame 1; a limiting mechanism, which is arranged at the bottom of the bed frame 1 and is used to limit and fix the extension mechanism; a sliding mechanism, which is fixedly arranged on the inner wall of the bed frame 1 and assists the extension mechanism in sliding use; and a supporting mechanism, which is arranged outside the bed frame 1.

[0027] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 , the extension mechanism includes an extension inner frame 7, a bed foot cross brace 16 and a roller 9;

[0028] Two extended inner frames 7 are slidably connected to one side of the bed frame 1, and a bed foot cross brace 16 is fixedly connected between the two extended inner frames 7, so that the two extended inner frames 7 can be slidably adjusted and fixed for use at the same time through the bed foot cross brace 16; at the same time, rollers 9 are rotatably connected to the upper and lower sides of one end of the extended inner frame 7 away from the bed foot cross brace 16, so that when the extended inner frame 7 is used for sliding adjustment, it can be assisted by a number of rollers 9 for sliding adjustment, so as to facilitate the extension of the use length of the bed frame 1 by the extended inner frame 7, so that it is convenient for patients to adjust it when using it.

[0029] refer to Figure 2 , Figure 4 , Figure 6 and Figure 7 The limiting mechanism includes a positioning pin 8, a rear hole 10, a front hole 15, a pin sleeve 11, a pin 12 and a wrench 13;

[0030] By fixing a positioning pin 8 on the top of the extended inner frame 7, the positioning pin 8 can limit the extended inner frame 7 to prevent the extended inner frame 7 from falling off from the inside of the bed frame 1; and a rear hole 10 and a front hole 15 are opened at the bottom of the extended inner frame 7. When the extended inner frame 7 needs to be slid out of the inside of the bed frame 1 for extended use, the extended inner frame 7 is pulled out first, and the restriction on the pin 12 is loosened by rotating the wrench 13 at the bottom of the bed frame 1, so that the pin 12 is engaged with the inside of the rear hole 10 through the spring arranged in the pin sleeve 11, and the pulled out extended inner frame 7 is limited and fixed; when the extended inner frame 7 is not needed for extended support, the extended inner frame 7 is retracted into the inside of the bed frame 1, and the pin 12 is engaged with the inside of the front hole 15.

[0031] refer to Figure 2 , Figure 4 and Figure 8 , the sliding mechanism includes a sliding sleeve 14, an external wall 17 and an internal hole 18;

[0032] By fixing the sliding sleeve 14 in the inner wall of the bed frame 1, the extended inner frame 7 can be assisted in sliding by the sliding sleeve 14 when it is used for sliding adjustment. At the same time, an external wall 17 is integrally formed on the outer wall of the sliding sleeve 14. The outer surface of the external wall 17 is set to be a rough surface, which is convenient for fixing the sliding sleeve 14 to the inner wall of the bed frame 1 with screws. Secondly, the internal connection hole 18 integrally formed on the inner wall of the sliding sleeve 14 is relatively smooth, which is convenient for sliding adjustment with the extended inner frame 7.

[0033] In addition, the sliding sleeve 14 can limit the positioning nail 8 to prevent the extended inner frame 7 from falling off from the inside of the bed frame 1.

[0034] refer to Figure 1 and Figure 3 , the support mechanism includes a support base 2, a bed head 4 and a bed foot 6;
