Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic pressure elements, in particular to a fixing device of an air source processor and the air source processor. Background Art

[0002] The air source processor includes a plurality of air source processing parts formed by splicing and assembling. A fixing device capable of connecting and fixing two air source processing parts and docking the two air outlets is provided at the air outlet of the air source processing part. The existing fixing device can refer to the Chinese patent with announcement number CN202194889U, which discloses a fixing device of the air source processor. The device includes a mounting block and a mounting plate, which are connected by two bolts. When the bolts are tightened, the distance between the two can be reduced. The device also includes bosses protruding from both sides of the air source processing part. The wall surfaces on both sides of the boss can abut against the end faces opposite to the mounting block and the mounting plate. A groove is recessed on the opposite side of the mounting block and the mounting plate. Mounting wings capable of being inserted into the groove are protruding from both sides of the boss. A sealing member is also provided between the air source processing parts.

[0003] When assembling the above-mentioned air source processor, people need to first connect the air outlets of the air source processing parts in pairs, place a seal between the two air outlets, and keep the three in a docking state to prevent the seal from being separated from the installation position, and then drive the groove on the mounting block to engage with the mounting wing from one side of the boss. After engaging, people need to simultaneously stabilize the docking state of the two air source processing parts and the engaging state of the mounting wing and the groove, and then drive the groove on the mounting plate to engage with the mounting wing on the other side. At this time, pinching the mounting block and the mounting plate from both sides can prevent the air source processing parts from being separated. Finally, while keeping the mounting block and the mounting plate pinched, tighten the bolts to complete the assembly. Therefore, the above-mentioned fixing device lacks a pre-positioning function. During the assembly of the air source processor, the two air source processing parts need to be kept docked at all times, which makes assembly inconvenient. Therefore, there is still room for improvement in the existing air source processor fixing device. Utility Model Content

[0004] Aiming at the disadvantage that the existing fixing device of the air source processor lacks the pre-positioning function and causes inconvenience in assembly, the first object of the utility model is to provide a fixing device of the air source processor with the pre-positioning function.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A fixing device for an air source processor comprises a mounting seat, on which a mounting position for docking an air source processing component is arranged, between which an introduction portion is arranged for guiding the air source processing components from both sides of the mounting position into the mounting position until they dock with each other and restricting the two air source processing components from moving away from each other, and a limiting component is arranged on the mounting seat for restricting the air source processing components from moving away from the mounting position along the guide.

[0007] By adopting the above scheme, in the prior art, the two air source processing components need to be manually maintained in a docking state until the bolts are tightened, while the present scheme only requires the cooperation of the introduction part and the mounting seat after the air source processing components are docked to limit the air source processing components from being moved away from each other. When the limiting parts are subsequently installed, there is no need to manually maintain the docking state of the air source processing components, thus realizing the function of pre-positioning and reducing the difficulty of assembling the air source processing components.

[0008] Preferably, the mounting position includes a mounting groove recessed in the side surface of the mounting seat and passing through the two end surfaces of the mounting seat, the introduction portion includes a first guide groove recessed along the opening direction of the two side walls of the mounting groove and a guide block guided and slid into the mounting groove along the first guide groove, the guide block is sealed and fixedly arranged on the air source processing component, and a gas delivery port connected to the inner cavity of the air source processing component is opened on the guide block.

[0009] Preferably, the guide blocks on the two gas source processing components are sealed and butted against each other via a sealing member, and a pre-positioning component for pre-positioning and installing the sealing member is also provided in the installation position.

[0010] Preferably, the pre-positioning assembly includes a second guide groove opened on the side wall of the first guide groove and a retaining frame fixed to the outer ring of the seal and slidingly cooperating with the second guide groove, and the second guide groove is centrally arranged on both sides of the mounting seat.

[0011] By adopting the above scheme, the seal is made of a material with good elastic deformation ability, and the air source processing component is easily deformed after being pressed. Therefore, the air source processing component must be installed in the installation groove while being connected to ensure that the seal is in the correct position and maintains sealing. The retaining frame in this scheme can keep the seal from being subjected to radial extrusion force. Therefore, the seal in this scheme can be placed in the installation groove in advance, and then the air source processing components are installed on both sides of the seal. Compared with the prior art, there is no need to place the seal between the two air source processing components in advance, and install the three into the installation groove at the same time, which further reduces the difficulty of installation.

[0012] Preferably, the thickness of the retaining frame is smaller than the thickness of the sealing element.

[0013] The above solution is adopted to reserve axial elastic deformation space for the seal, so that the seal and the air source processing component can fit more closely.

[0014] Preferably, the limiting member includes a mounting plate that can block the mounting position opening from the end of the mounting seat and abut against one side of the guide block, the side of the guide block facing away from the mounting plate abuts against the inner wall of the mounting groove, and a fastener is provided between the mounting plate and the mounting seat to connect and fix the two to each other.

[0015] Preferably, the fastener comprises a pair of bolts passing through the mounting plate, and the mounting seat is provided with threaded holes matching with the bolts.

[0016] By adopting the above scheme, compared with the prior art, the function of the mounting plate in this scheme is only to limit the guide block to disengage along the first guide groove, and the air source processing component has been limited in the mounting groove before installing and locking the mounting plate, which is more convenient to install.

[0017] The second object of the utility model is to provide an air source processor, comprising at least two air source processing parts, which are docked and fixed by a fixing device, and the fixing device comprises a fixing device as described in any one of the above-mentioned schemes for docking and fixing.

[0018] Preferably, the guide block is integrally provided with the air source processing component.

[0019] By adopting the above scheme, the existing air source processing component can be assembled with the fixing device in the above scheme to simplify the assembly process. In this scheme, the guide block and the air source processing component are set together. This method can prevent air leakage to the greatest extent and ensure the air tightness of the air source processing component. The outer shell of the existing air source processing component generally adopts an integrated molding production method. The guide block is designed as a part of the air source processing component shell and can be produced together with the shell. There is no need to set up additional processing steps, which saves production costs.

[0020] The utility model has significant technical effects due to the adoption of the above technical scheme: in the prior art, the two air source processing parts need to be manually maintained in a docking state until the bolts are tightened, while the present scheme only requires the introduction part to cooperate with the mounting seat after the air source processing parts are docked to limit the air source processing parts from each other, and there is no need to manually maintain the docking state of the air source processing parts during the subsequent installation of the limiting parts, thereby realizing the function of pre-positioning and reducing the difficulty of assembling the air source processing parts. In addition, in the present scheme, the retaining frame can be used to make the sealing part have a certain resistance effect when subjected to radial extrusion force, which can realize distributed installation of the air source processing parts and the sealing parts, thereby further reducing the difficulty of assembly.

DETAILED DESCRIPTION

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Example

[0029] A gas source processor, according to Figures 1-2 As shown, it includes two air source processing components 2, which are connected and fixed by a fixing device. Figures 2-3 As shown, the fixing device includes a mounting seat 1, a side recess of the mounting seat 1 is provided with a mounting groove 3 that penetrates the two end surfaces of the mounting seat 1, and a first guide groove 4 is provided on the inner opposite side walls of the mounting groove 3. A guide block 5 that can slide along the first guide groove 4 and enter the mounting groove 3 is integrally provided on the air source processing component 2, and a gas delivery port 51 that is connected to the inner cavity of the air source processing component 2 is opened on the guide block 5, and the guide blocks 5 are sealed and connected by a sealing member 7.

[0030] In this embodiment, the sealing member 7 is a sealing ring, and a pre-positioning component for pre-positioning and installing the sealing member 7 is provided in the installation position. Figure 3 As shown in Fig. 5, the pre-positioning assembly includes a second guide groove 6 opened on the side wall of the first guide groove 4, and a retainer 71 is fixed to the outer ring of the seal 7. The retainer 71 can guide and slide into the second guide groove 6. The second guide groove 6 is centrally arranged on both sides of the mounting seat 1. The thickness of the retainer 71 is less than the thickness of the seal 7. Figure 3 As shown, the thickness of the retaining frame 71 is smaller than the thickness of the sealing member 7 .

[0031] The mounting seat 1 is provided with a limiting member to limit the air source processing member 2 from moving away from the mounting position along the first guide groove 4. Figure 3 As shown in or 5, the limiting member includes a mounting plate 8 that can block the mounting position opening from the end of the mounting seat 1 and abut against one side of the guide block 5. When the mounting plate 8 is in contact with the mounting seat 1, the other side of the guide block 5 can be driven to abut against the inner wall of the mounting groove 3. A bolt 9 is provided between the mounting plate 8 and the mounting seat 1 to connect and fix the two. The bolt 9 is passed through the mounting plate 8, and a threaded hole 11 that cooperates with the bolt 9 is opened on the mounting seat 1.

[0032] Combined with the above structure, reference Figures 1 to 5 It can be seen that the assembly process of an air source processor in this embodiment is as follows:

[0033] First, align and insert the guide blocks 5 on the air source processing component 2 into the first guide groove 4 respectively. Then, pinch the mounting seat 1 with one hand and let the mounting seat 1 keep the opening of the mounting groove 3 tilted upward to prevent the guide block 5 from sliding out along the first guide groove 4. Then pick up the seal 7, align the retaining frame 71 with the second guide groove 6 and insert it to make the air source guide block 5 and the seal 7 seal against each other. Finally, use the bolts 9 to connect the mounting plate 8 and the mounting seat 1 to fix the guide block 5 to complete the assembly.

[0034] In the prior art, the two air source processing components 2 need to be manually maintained in a docking state until the bolts 9 are tightened, while the present solution only requires the introduction portion to cooperate with the mounting seat 1 after the air source processing components 2 are docked to limit the air source processing components 2 from being moved away from each other. When the limiting components are subsequently installed, there is no need to manually maintain the docking state of the air source processing components 2, thereby realizing the pre-positioning function and reducing the difficulty of assembling the air source processing components 2. In addition, in the present solution, the retaining frame 71 can be used to ensure that the sealing component 7 has a certain resistance effect when subjected to radial extrusion force, which enables the air source processing component 2 and the sealing component 7 to be installed in a distributed manner, thereby further reducing the difficulty of assembly.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
