Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a deformable walker. Background Art

[0002] Orthopedic patients often need to use crutches or walkers to assist walking, but existing walkers may have limitations in use. For example, it is more convenient to use a walker on a flat surface, but when climbing stairs or climbing high, the walker cannot be used and only a cane can be used. Therefore, there is an integrated walker in the prior art that can transform the walker into a cane.

[0003] Currently, the modification of the integrated walker is usually concentrated on the crossbeam part. By disassembling and assembling the crossbeam between the support frames on both sides, the whole device can be switched between the walker and crutch form.

[0004] However, in order to ensure the stability of the overall structure, the existing walker usually has two crossbeams, namely a top crossbeam and a side crossbeam. The method of disassembling and assembling the two crossbeams separately is rather troublesome in actual use, and the two crossbeams have a total of four joints that are connected to the support frame by a one-by-one clamping method, which is inconvenient and inefficient. Utility Model Content

[0005] The utility model aims to provide a deformable walker to solve the technical problem in the prior art that the two cross beams with four joints are gradually connected to the support frame, which causes inconvenience in use.

[0006] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0007] A deformable walker, comprising two side support frames, wherein a turning rod is telescopically arranged inside the side support frames, and a structural crossbeam is arranged between the two side support frames, wherein the structural crossbeam comprises a top crossbeam connected to the top of the side support frame and a side crossbeam connected to the side of the side support frame, wherein the top crossbeam and the side crossbeam are connected by an integral rod;

[0008] The structural beam is connected to the side support frame through a connecting assembly, and the connecting assembly includes connecting male heads respectively arranged at the ends of the structural beam and connecting female heads arranged at corresponding positions of the side support frame, and the connecting male heads are engaged with the connecting female heads by pulling upwards.

[0009] As a preferred solution of the utility model, the connecting female head includes a cover tube installed on the side support frame, and the cover tube is provided with double-sided elastic clips. The connecting male head includes a clip-on end column arranged at the end of the structural beam, and the end of the clip-on end column is connected with an inner concave arc groove, and the inner concave arc groove cooperates with the double-sided elastic clips to clip the clip-on end column in the cover tube.

[0010] As a preferred solution of the utility model, the double-sided elastic clip includes two raised nodes symmetrically arranged on the inner wall of the cover tube, an elastic member is arranged inside the raised node, a nodule head is arranged on the elastic member, and the nodule head protrudes from the raised node toward the center of the cover tube.

[0011] As a preferred solution of the utility model, an external thread is provided on the outer wall of the cover tube, and an assembly sleeve is slidably provided on the outside of the clamping end column. The assembly sleeve is arranged on the outside of the cover tube and is connected to the cover tube by threaded engagement, wherein the external thread on the outer wall of the cover tube is arranged at a position away from the end of the cover tube.

[0012] As a preferred solution of the utility model, a clamping chuck for connecting with the end side of the structural beam is provided on the side of the side support frame.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model uses an integrated rod to connect the top crossbeam and the side crossbeam to form a whole. Therefore, when in use, two crossbeams can be clamped at one time without connecting the top crossbeam and the side crossbeam separately, thereby improving the efficiency of disassembly and assembly. In addition, the connection assembly is further connected to the side support frame by a single lifting method without the need to clamp the four joints of the structural crossbeam one by one, thereby making the overall connection process lighter and faster, and more efficient to use.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1 to Figure 2 As shown, the utility model provides a deformable walker, including two side support frames 1, a turning rod 2 is telescopically arranged inside the side support frames 1, a structural beam 3 is arranged between the two side support frames 1, the structural beam 3 includes a top beam 4 connected to the top of the side support frame 1 and a side beam 5 connected to the side of the side support frame 1, and the top beam 4 and the side beam 5 are connected by an integrated rod 6.

[0022] The structural beam 3 is connected to the side support frame 1 through a connecting assembly, which includes a connecting male head 7 respectively arranged at the end of the structural beam 3 and a connecting female head 8 arranged at the corresponding position of the side support frame 1. The connecting male head 7 is engaged with the connecting female head 8 by pulling upward.

[0023] When the device is used, the structural crossbeam 3 is disassembled to release the side support frames 1 on both sides to form a single structure for use, so as to simulate the use of a crutch on the corresponding terrain, thereby completing the transformation of the overall device from a walker to a crutch and vice versa.

[0024] like Figure 1 As shown, in terms of structural design, the top crossbeam 4 and the side crossbeam 5 are connected together by an integral rod 6 to form an integral structure, so that in actual use, the structural crossbeam 3 formed by the top crossbeam 4 and the side crossbeam 5 can be directly installed on the side support frame 1, omitting the steps of separately installing the top crossbeam 4 and the side crossbeam 5.

[0025] In addition, in the specific installation and clamping steps, the device directly lifts the structural beam 3 so that its end can be directly connected to the connecting position of the side support frame 1, thereby simplifying the operation of connecting the ends of the structural beam 3 one by one.

[0026] Specifically, the connecting female head 8 includes a cover tube 9 installed on the side support frame 1, and a double-sided elastic clip 10 is arranged in the cover tube 9. The connecting male head 7 includes a clip-on end column 11 arranged at the end of the structural beam 3, and the end of the clip-on end column 11 is connected with an inner concave arc groove 12. The inner concave arc groove 12 cooperates with the double-sided elastic clip 10 to clip the clip-on end column 11 in the cover tube 9.

[0027] The double-sided elastic clip 10 includes two raised nodes 13 symmetrically arranged on the inner wall of the cover tube 9 , an elastic member 14 is arranged inside the raised node 13 , a node head 15 is arranged on the elastic member 14 , and the node head 15 protrudes from the raised node 13 and is arranged toward the center of the cover tube 9 .

[0028] like Figure 2 As shown, when the clamping end column 11 is inserted into the cover tube 9, due to the special design of the concave arc groove 12 at the end of the clamping end column 11, when it is just inserted, its end will push the nodule heads 15 on both sides to retract into the raised section 13, and when it is further inserted so that the concave arc groove 12 enters the position of the raised section 13, the nodule head 15 will be pushed by the elastic member 14 and protrude from the raised section 13 again, and inserted into the concave arc groove 12 of the end of the clamping end column 11, thereby forming a clamping connection with the connecting male head 7. When it is necessary to disassemble the structural crossbeam 3, the structural crossbeam 3 is directly pulled downward to make the nodule head 15 escape from the concave arc groove 12, thereby completing the disassembly of the structural crossbeam 3. This disassembly and assembly method is simple and convenient. As for the structural strength, since the structural crossbeam 3 serves to connect the side support rods on both sides during specific use, it is not subjected to direct vertical downward force during specific use. Therefore, this type of snap-on connection will not fall apart during specific use and can be used normally.

[0029] Furthermore, an external thread 16 is provided on the outer wall of the cover tube 9, and an assembly sleeve is slidably provided on the outside of the clamping end column 11. The assembly sleeve is arranged on the outside of the cover tube 9 and is connected to the cover tube 9 by threaded engagement, wherein the external thread 16 on the outer wall of the cover tube 9 is arranged at a position away from the end of the cover tube 9.

[0030] The assembly sleeve is set at the connection position of the structural cross beam 3 and the side support frame 1 as a double insurance to ensure the structural strength of the whole device. In actual use, it is not necessary to set four assembly sleeves. Only two assembly sleeves need to be set at the relative angles of the top cross beam 4 and the side cross beam 5. The connection between the two assembly sleeves and the cover tube 9 can stabilize the whole structure.

[0031] Among them, the external thread 16 arranged on the outside of the cover barrel 9 is to be arranged between the surface of the side support frame 1 and the double-sided elastic clamping piece 10. That is to say, in actual use, it is necessary to first clamp the clamping end column 11 with the double-sided elastic clamping piece 10, and then slide the assembly sleeve to make it contact with the external thread 16, and further rotate it to connect with the cover barrel 9. This requires that the external thread 16 on the outside of the cover barrel 9 is arranged at the rear side of the double-sided elastic clamping piece, and it cannot be arranged at a position close to the opening of the cover barrel 9, but is arranged at the bottom of the cover barrel 9 between the side support frame 1 and the double-sided elastic clamping piece 10.

[0032] In addition, the side support frame 1 is provided with a clamping head 17 for connecting with the end side of the structural beam 3. After the structural beam is removed, the structural beam can be erected and clamped on the clamping head 17, so that the removed structural beam 3 can be conveniently moved together and can be taken at any time when used next time.

[0033] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
