For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Example 1 like Figure 1As shown, a lifting bed rail includes a railing 100, a set of gas springs 200 symmetrically arranged on the left and right sides of the railing 100, and outer sliders 300 symmetrically arranged on the left and right sides of the railing 100, located outside the gas springs 200 respectively, and allowing the railing to slide up and down along them.

[0030] When open, the guardrail can move up and down along the outer slider. The gas spring ensures that the guardrail will not fall due to gravity when no external force is applied, effectively preventing the guardrail from falling and hitting people or getting caught in the bed frame, thus improving the safety of the product.

[0031] like Figures 2-4 As shown, the guardrail 100 consists of a guardrail body 110, two switch boxes 120 disposed on the outer side of the guardrail body 110, two sliding locks 130 disposed inside the upper horizontal bar of the guardrail body 110 and respectively cooperating with the two switch boxes 120, two vertical side rails 140 respectively disposed on the left and right sides of the guardrail body 110, and corner connecting blocks 150 disposed at the upper and lower ends of the vertical side rails 140 and respectively connected to the upper and lower horizontal bars of the guardrail body 110.

[0032] The spacing between the two switch boxes can be selected according to actual usage needs, preferably greater than the distance between a child's outstretched arms. This is to more effectively prevent children from accidentally turning on the switch and causing the guardrail to lower, further improving the product's safety. Because of the gas spring, the product will not lower when only one switch box is open, thus ensuring that children who can only operate with one hand will not open the guardrail themselves, effectively preventing patients from falling off the bed due to the guardrail being opened.

[0033] like Figure 5 As shown, the sliding lock 130 consists of a rear top block 131 installed inside the horizontal bar on the upper side of the guardrail body 110, a pull rod 132 with its rear end bent into a collar 133 and its front end passing through the rear top block 131, a lock head 134 installed at the front end of the pull rod 132, and a spring 135 with its two ends fixed to the rear top block 131 and the lock head 134 respectively and sleeved on the pull rod 132.

[0034] The sliding lock is an existing technology. Because the collar and the switch box cooperate, and the rear top block is fixed, the lock head will remain in an outward-extending state under the action of the spring when there is no external force. In actual use, it needs to be used in conjunction with the lock holes and half slots on both sides of the guardrail to ensure that the sliding lock can be inserted into the lock hole or half slot when there is no external force, thereby limiting the movement range of the guardrail. Those skilled in the art can complete the setting and use of the sliding lock and lock hole without creative labor, so it will not be described in detail here.

[0035] The vertical side rail 140 consists of a side rail body 141, an embedding groove 142 located on the outside of the side rail body 141 and extending through the side rail body 141 both vertically and vertically, and slide rails 143 respectively vertically mounted on the two side walls of the embedding groove 142.

[0036] The recessed groove is used to install a gas spring. The pressure cylinder of the gas spring is fixed to the bottom of the groove, allowing the force of the gas spring to be fully applied to the guardrail. It can be fixed by screws, glue, or a snap-fit ​​structure. These fixing methods are all existing technologies in the field, and those skilled in the art can choose the appropriate fixing method according to actual usage requirements; therefore, they will not be elaborated upon here.

[0037] The corner connecting block 150 consists of a connecting block body 151, a connecting hole 152 that runs horizontally through the connecting block body 151 and is connected to the upper horizontal bar of the guardrail body 110, and a vertical through groove 153 that runs vertically through the connecting block body 151 and is connected to the embedded groove 142; one side of the connecting block body 151 is connected to the end of the upper or lower horizontal bar of the guardrail body 110, and the other side is connected to the upper or lower end of the side rail body 141.

[0038] The purpose of the connecting hole is to ensure that the lock cylinder can pop out normally, while the vertical through slot ensures that the gas spring can extend normally from the bottom of the product after it is fixed. It should be noted that the upper end of the gas spring should not be installed beyond the connecting hole of the upper corner connecting block to avoid the gas spring blocking the lock cylinder from popping out.

[0039] The gas spring 200 consists of a pressure cylinder 210, a piston rod 220 extending downward from the pressure cylinder 210, and a connector 230 located at the bottom end of the piston rod 220.

[0040] Gas springs are existing technology, and the connectors are mainly used to fix them to the ground or bed frame structure. Those skilled in the art can complete their setup and use without creative labor.

[0041] like Figure 2 As shown, the pressure cylinder 210 is vertically fixed in the embedding groove 142, and the lower end of the pressure cylinder 210 extends downward into the vertical through groove 153 located below.

[0042] like Figure 6 , Figure 7As shown, the outer slider 300 consists of a slider body 310, slide rail grooves disposed on both sides of the slider body 310 and respectively cooperating with two slide rails 143, several vertically arranged lock holes 320 horizontally penetrating the slider body 310 and matching the lock head 134, and several half-grooves 330 disposed on the inner side of the slider body 310 and connected to the lock holes 320 at their lower ends, with a width matching the lock head 134; the half-grooves 330 are provided on all the lock holes 320 except for the two lock holes 320 located at the top and bottom ends.

[0043] Among them, the half-groove is a blind groove, while the lock hole is a through hole or a blind hole with a depth greater than that of the half-groove.

[0044] Since guardrails are usually limited in their vertical movement range during use, when the guardrail moves to its highest or lowest position, the lock head pops out and can directly extend into the lock hole, so there is no need to set a half slot hole for cooperation.

[0045] The locking head 134 of the sliding lock 130 extends out of the connecting hole 152 and is pressed against the inside of the slider body 310 by the spring 135.

[0046] Because of the semi-groove, the product of this embodiment has an additional semi-locked state in addition to the existing locked and unlocked states of the guardrail. The three states are as follows: (1) Locked state: the lock head is inserted into the lock hole, so that the guardrail is kept at a certain height and cannot move up or down; (2) Unlocked state: the lock heads on both sides of the guardrail are disengaged from the outer slider, and the guardrail can move up and down along the outer slider under the action of the gas spring or human force; (3) Semi-locked state: the lock head pops out and enters the semi-groove, and the guardrail needs to be manually moved down to enter the lock hole. The purpose of the semi-locked state is to reduce the difficulty of adjusting the height of the guardrail. Especially when the guardrail moves up or down at high speed, the lock head may have already passed through the lock hole to which it needs to be inserted before popping out. The semi-groove provides sufficient time and distance for the lock head to pop out. After the lock head enters the semi-groove, the user can easily and quickly adjust the guardrail to the lock hole connected to the semi-groove by pressing down, which further reduces the difficulty of using the product.

[0047] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0048] Furthermore, the specific embodiments described above are exemplary. Those skilled in the art can devise various solutions inspired by the disclosure of this utility model, and these solutions all fall within the scope of this utility model and its protection. Those skilled in the art should understand that this utility model specification and its drawings are illustrative and not intended to limit the scope of the claims.
