Description

Casing for medical equipment

Technical Field

The present invention relates to a housing for a medical device.

Background

The height of the existing medical equipment, such as a medical oxygen generator and the like, can reach 40-60 cm, and the width and the depth can reach 30cm, so that the existing medical equipment belongs to equipment with larger volume. The housing of such a device is usually divided into a plurality of housing parts made of plastic, the largest proportion of the total housing area being the housing parts on the side.

One of the existing side shell members is composed of two plastic shell members, one of the plastic shell members is formed with a plurality of screw connection posts, the other plastic shell member is formed with corresponding screw through holes, and the two plastic shell members can be fastened together by screws penetrating through the screw through holes and being fastened to the screw connection posts. However, more screw through holes can be observed on the side shell, which affects the appearance of the product, and the two plastic shell parts are manufactured by different molds, because the area of the plastic shell part is larger, the manufacturing cost of the mold is higher.

Another type of side shell element is known, which comprises several plastic shell elements, but which are connected to a load-bearing frame in a machine by means of claws and/or screws. Although the structure can reduce the manufacturing cost of the mold to a certain extent (for example, in the case that the shapes and the structures of some plastic shell pieces are the same), the manufacturing of the internal stress frame is also cost-consuming, so that the structure cannot save much cost, and the number of screws used is large, thus being not beautiful.

There is therefore a need for an improved housing structure for such medical devices.

Disclosure of Invention

The invention provides a shell for medical equipment, which aims to solve the problems of high manufacturing cost, inconvenience in maintenance and the like of the existing product.

The following technical scheme is adopted:

a shell for medical equipment comprises a top shell, side shells and a chassis; in particular, the side housing comprises several side housing pieces; at least 1 left connecting lug part and at least 1 right connecting lug part are formed on the single side shell part, the left connecting lug part is formed on one side of the side shell part, and the right connecting lug part is formed on the other side of the side shell part; the adjacent side shell pieces are fastened together through the connection of the left connecting ear of one and the right connecting ear of the other, and the side shell pieces enclose a barrel shell, and one end of the barrel shell is formed into a necking which is used for partially enveloping the chassis to fix the position of the chassis and transmit lifting force from the outside to the chassis; at least 1 of the side housing pieces also fixes the position of the top housing with the top housing by the engagement of the flange with the catch groove and serves to transmit forces between the top housing piece and the side housing piece.

The design principle of the invention is as follows:

through the technical scheme, the side shell can be formed by connecting a plurality of side shell pieces with the same shape and size, and only one set of die is needed for producing the side shell pieces, so that the cost of the die is greatly saved. On this basis, this technical scheme still solves the problem of location and power transmission between side casing and the top surface casing through the cooperation of flange and draw-in groove to and solve the problem of location and power transmission between side casing and the chassis through the throat structure of side casing, realized the effect of "shell is the skeleton".

For a one-piece side shell member, the left and right attachment ears thereof may each be provided with a screw hole. Therefore, the adjacent side shell pieces, the left connecting lug part of one side shell piece and the right connecting lug part of the other side shell piece are overlapped together and then are screwed tightly at the overlapped part, so that the two side shell pieces can be connected and fastened.

Or, for the single side shell part, the left connecting lug part is provided with a first mortise and tenon joint part, and the right connecting lug part is provided with a second mortise and tenon joint part; the first tenon-and-mortise part is one of the pin-and-tenon structures, and the second tenon-and-mortise part is the other of the pin-and-tenon structures. Thus, the adjacent side shell parts, the first mortise and tenon parts of one part and the second mortise and tenon parts of the other part are mutually inserted to form an unlocked mortise and tenon state, and then the mortise and tenon parts used as the mortise and tenon are installed, so that the two side shell parts can be connected together in a pin and tenon structure. The advantage of doing so has reduced the use quantity of screw, also can realize exempting from the screw dismouting, brings certain facility for the maintenance work in later stage. In order to improve the connection reliability, the first mortise and tenon part and the second mortise and tenon part are preferably also provided with a concave-convex guiding fit, and the guiding direction of the guiding fit is the inserting and combining direction of the first mortise and tenon part and the second mortise and tenon part.

Detailed Description

The present invention will be further described with reference to the following examples.

Example 1

As shown in fig. 1 and 2, a medical device case according to the present embodiment includes: a top case 1, a side case 2, and a chassis 3.

As shown in fig. 3, the top surface case 1 is provided with a handle portion 11 and an operation panel area 12. Side walls are also formed on the

top housing

1, and 1 flange 13 is formed on each of the two oppositely disposed side walls, and these 2 flanges 13 are intended to cooperate with the catch grooves 211 on the side housing pieces 21 described below.

As shown in fig. 3 and 9, the side case 2 of the present embodiment includes 2 side case members 21 having the same shape and size. The end of the one-piece side shell member 21 facing the top shell 1 is further provided with 2 sets of notches 211, and the 2 sets of notches 211 are simultaneously matched with the 1-way flange 13 of the top shell 1 to transmit vertical force between the top shell 1 and the side shell 2. In the case of 2-channel flanges 13 in total and 4 sets of card slots 211 in total, this vertical force can be distributed.

As shown in fig. 3, 4, 5, and 6, the single-piece side housing piece 21 has 3

left attachment ears

212 and 3 right attachment ears 213 formed thereon. 3 left coupling lugs 212 are formed at one side of the

side case member

21, and 3 right coupling lugs 213 are formed at the other side of the side case member 21. The left connecting lug 212 has a first mortise and tenon portion 2121, and the right connecting lug 213 has a second mortise and tenon portion 2131. The first mortise and tenon part 2121 of the present embodiment is further formed with a concave position 2122; the second mortise and tenon part 2131 of this embodiment further has a bump 2132. The concave 2122 and the convex 2132 form a guiding fit, and the guiding direction of the guiding fit is the inserting and combining direction of the first mortise and tenon part 2121 and the second mortise and tenon part 2131.

The first mortise and tenon part 2121 of the present embodiment is one of the pin and tenon structures, and the second mortise and tenon part 2131 is the other of the pin and tenon structures. Thus, the first mortise and tenon portion 2121 of one side casing member 21 and the second mortise and tenon portion 2131 of the other side casing member 21 are inserted into each other to form an unlocked mortise and tenon state, and thereafter, the two side casing members 21 are connected together in a pin-and-tenon structure by simply installing the mortise and tenon member 214 for mortise and tenon. The tenon member 214 may be formed with a portion that is easily held by hand to facilitate insertion and removal of the tenon member 214.

As shown in fig. 4, the end of the one-piece side case member 21 facing the chassis 3 is also formed with a bent portion 215. Thus, as shown in fig. 7, when the two side housing members 21 are fastened together to thereby enclose the cartridge housing 22, one end of the cartridge housing 22 is formed as a throat 221. As shown in fig. 9, the throat 221 will partially enclose the chassis 3. That is, the chassis 3 is enclosed in the cylinder housing 22 when the two side housing members 21 are connected together, and since the chassis 3 is configured to be limited in shape and size in the cylinder housing 22 and cannot pass through the throat 221, the position of the chassis 3 in the side housing 2 is limited in fact, and when the side housing 2 transmits an external lifting force, the lifting force is transmitted to the portion of the chassis 3 facing the ground, that is, the lifting force is transmitted to the chassis 3 in an "upward-supporting" manner. Because the contact area between the side shell 2 and the chassis 3 can be easily made larger, the pressure intensity of the relevant part of the side shell 2 is smaller, and the problem of local fracture and damage of the side shell 2 can be avoided by the upward-supporting force transmission mode and the structure.

The lifting force is used for lifting the whole machine away from the placing position. In the present embodiment, as shown in fig. 9, the transmission path of the lifting force is such that: the handle part 11 of the top shell 1 is stressed by upward force, the flange 13 and the clamping groove 211 are matched to transmit the upward force to the side shell 2, the side shell 2 transmits the upward force to the lower part of the chassis 3 through the necking opening 221 thereof, and the chassis 3 and equipment arranged on the chassis 3 are lifted away from the placing position in an upward supporting mode.

As shown in fig. 1, 2, and 3, in the present embodiment, a decorative plate 4 is further provided between adjacent side casing members 21. The trim plate 4 is for shielding and protecting the left and

right coupling ears

212 and 213. As shown in fig. 3, a plurality of holding portions 41 are formed on the side of the decorative plate 4 contacting the side case member 21. The clip portion 41 serves to define the relative position between the trim panel 4 and the side case member 21. The plaque 4 of the present embodiment is also connected to the chassis 3 by screws.

As shown in fig. 3, 2 auxiliary supporting member connecting positions 14 are further provided on the top surface case 1, and the 2 auxiliary supporting member connecting positions 14 are formed on the side walls arranged to face each other on both sides. The auxiliary support member connection site 14 of this embodiment is a slot site. In the assembly of the complete machine, 2 auxiliary supporting pieces can be included, one end of each auxiliary supporting piece is fixed on the chassis 3 or equipment on the chassis 3, and the other end of each auxiliary supporting piece is inserted into the auxiliary supporting piece connecting position 14. In this way, the top housing 1 can be in a relatively fixed position without the side housing 2 being installed, facilitating assembly and pipeline connection of the complete machine.

Example 2

The present embodiment is different from embodiment 1 in that: as shown in fig. 10, the left and right coupling ears 212b and 213b of the side case member 21b are each a flat projection provided with a screw hole 216. Thus, the adjacent side housing members, the left connecting ear 212b of one member overlapping the right connecting ear 213b of the other member, are fastened together by screws at the overlapping portions.

The description is only a preferred embodiment of the invention, and all technical equivalents which come within the spirit and scope of the invention are intended to be protected.
