The glass window frame comprises a pair of upper and lower transverse frames which are vertically separated and transversely extend and a glass plate connected between the upper and lower transverse frames. The above features define the main components of the glazing frame. In contrast to the conventional construction of the glazing frame, the glazing frame of the invention omits a pair of left and right spaced vertical borders.

The clamping groove is a groove part arranged on the upright post of the cabinet body and is provided with a groove bottom wall and a pair of groove side walls which are arranged front and back. According to the requirement of a specific structure, a notch transverse wall which oppositely extends and narrows the notch part of the clamping groove can be arranged on the pair of the notch side walls.

The glazing frame omits a pair of left and right spaced vertical frames. This not only reduces the cost of manufacture of the mullion but also simplifies the construction and installation of the glazing frame.

2. Because friction positioner's connector stretches into in the joint recess with joint recess joint contact produces ascending frictional force and makes a pair of the both ends of upper and lower horizontal frame detachably location simultaneously arrives on the cabinet body stand. Thus, the friction positioning devices respectively arranged at the four corner positions of the glass window frame cooperatively offset the weight of the upper and lower transverse frames and the glass plate, so that the glass window frame cannot easily loosen and slide off. In addition, friction positioner's connector with joint recess joint is connected, can make again the glass window frame is fixed a position in front and back mode. Therefore, the friction positioning device can simultaneously position the glass window frame in the vertical direction and the front-back direction, so that the glass window frame can be stably and detachably positioned on the cabinet body upright post. Secondly, under the condition that the glass plate is also in a detachable connection relation with the pair of upper and lower transverse frames, when the glass plate is damaged, the connector of the friction positioning device on the upper transverse frame can be loosened to enable the upper transverse frame to move upwards to leave the glass plate, or the connector of the friction positioning device on the lower transverse frame can be loosened to enable the lower transverse frame to move downwards to leave the glass plate, so that enough space is formed between the pair of upper and lower transverse frames to detach the glass plate, and then the glass plate can be conveniently replaced without detaching the whole glass window frame from the cabinet body. The maintenance operation of the glass window frame is extremely convenient.

As regards the construction of the friction positioning device, there are several embodiments, one of which is proposed by the present invention: connecting cavities are respectively arranged at the left end part and the right end part of the transverse frame, and each connecting cavity is provided with a main cavity extending transversely and an auxiliary cavity arranged approximately vertical to the main cavity; friction positioner includes T type anchor post, tenon body and adapter sleeve, T type anchor post includes the anchor cylinder and is located the protruding connector of anchor cylinder one end, the adapter sleeve sets up vice intracavity, be provided with on the adapter sleeve and correspond to the jack of anchor cylinder, the anchor cylinder is pegged graft in the main intracavity and stretch into in the jack, the protruding connector joint of T type anchor post is in the joint recess of cabinet body stand, tenon body screw thread connects soon in the adapter sleeve and roof pressure are in make on the anchor cylinder protruding connector anchor is tightly on the joint recess.

Wherein the connecting cavity has a laterally extending main cavity and a secondary cavity arranged substantially perpendicular to the main cavity. The above features define the main structure of the connecting cavity, the main cavity of the connecting cavity extends laterally, and the auxiliary cavity of the connecting cavity can extend from front to back or from top to bottom so as to be arranged approximately perpendicular to the main cavity and communicated with the main cavity.

The tenon body is screwed on the connecting sleeve, the connection relation between the tenon body and the connecting sleeve is defined by the characteristics, the tenon body can be positioned on the transverse frame by means of the connecting sleeve, and the jacking strength of the jacking pressure on the anchoring column body can be adjusted by means of the screw thread screwing relation of the connecting sleeve, so that the anchoring force of the convex connecting head is adjusted. The arrangement of the connecting sleeve is also beneficial to omitting the inner cavity wall of the auxiliary cavity, and the inner cavity wall is provided with an inner thread screwed with the thread of the tenon body, so that the influence of the arrangement of the thread on the structural strength of the transverse frame and the structural limitation are reduced.

According to the technical scheme, the size of the anchoring force of the friction positioning device can be conveniently adjusted by rotating the tenon body. As for the anchoring mode of the convex connector, an inward contraction anchoring mode and an outward bracing anchoring mode can be adopted, and the further technical scheme can be that an inclined driving surface is arranged on the tenon body or the anchoring column body, and the tenon body can force the T-shaped anchoring column to retract inwards through the inclined driving surface so as to anchor the convex connector on the notch transverse wall of the clamping groove; or the tenon body can force the T-shaped anchoring column to extend outwards through the inclined driving surface so as to anchor the convex connecting head on the groove bottom wall of the clamping groove. Thus, the T-shaped anchoring column retracts inwards so as to enable the convex connecting head to be anchored on the transverse wall of the groove opening of the clamping groove in an anchoring mode, and the T-shaped anchoring column is in an inward-retracting anchoring mode. And the T-shaped anchoring column extends outwards so as to enable the convex connecting head to be anchored on the bottom wall of the clamping groove in an anchoring mode, and the anchoring mode belongs to an external-support anchoring mode.

As for the inclined driving surface, it may be selectively provided on the anchoring cylinder, and a further technical solution may be that a tapered hole or a tapered groove is provided on the anchoring cylinder, and a tapered surface of the tapered hole or the tapered groove becomes the inclined driving surface.

Therefore, the left end and the right end of the glass plate do not need to be matched with the cabinet body upright posts, so that the precision requirement on the transverse width dimension of the glass plate can be reduced. When the glass plate is assembled, the glass plate can be pre-installed on the pair of cabinet body upright posts by the pair of upper and lower transverse frames and is directly installed in a space defined by the pair of upper and lower transverse frames after being preliminarily positioned, and the glass plate does not need to be inserted between the pair of cabinet body upright posts from top to bottom. In the same way, when the glass plate is detached, the glass plate does not need to move from bottom to top to be detached from the pair of upright posts of the cabinet body. In addition, the horizontal gap can also be an air supplementing gap, so that the cabinet body has proper air inlet amount.

The technical scheme can also be that each transverse frame is provided with a positioning fixture block on the left end part and the right end part respectively, and the positioning fixture blocks extend into the clamping grooves of the upright posts of the cabinet body so as to reduce the front and back shaking of the glass window frame.

Due to the characteristics and advantages, the invention can be applied to cabinets with glass window frames, such as storage cabinets, ventilation cabinets and the like.

In order to detachably connect the glass window frame 2, a clamping groove 10 which vertically extends is formed in the side wall, facing the glass window frame 2, of the cabinet body stand column (1, 1 a). The clamping groove 10 is a groove part arranged on the upright post (1, 1 a) of the cabinet body and is provided with a groove bottom wall 101, groove side walls (102, 103) arranged at the front and the rear parts and a pair of groove opening transverse walls (104, 105) which are oppositely arranged and narrow the groove opening part of the clamping groove 10.

As shown in fig. 3, 4, 5 and 6, the window frame 2 includes a pair of upper and lower lateral frames (21, 21 a) spaced apart from each other in the up-down direction and extending in the lateral direction, and a glass plate 22 joined between the pair of upper and lower lateral frames (21, 21 a). Specifically, the upper horizontal frame 21 is shaped like a profile, an upper mounting groove 212 is formed on a side wall of the upper horizontal frame facing the glass plate 22, similarly, the lower horizontal frame 21a is shaped like a profile, a lower mounting groove (similar to the upper mounting groove 212 in structure, and related enlarged schematic drawings are omitted) is formed on a side wall of the lower horizontal frame facing the glass plate 22, and upper and lower edge portions of the glass plate 22 are respectively inserted into the upper mounting groove 212 and the lower mounting groove. In contrast to the conventional configuration of the glazing frame 2, the glazing frame 2 of the present invention omits a pair of left and right spaced vertical borders.

In order to connect the glass window frame 2 detachably to a pair of between cabinet body stand (1, 1 a), every be provided with friction positioner 3 on the left and right tip of horizontal frame (21, 21 a) respectively, include friction positioner (3, 3a, 3b and 3 c) respectively, the connector 311 of friction positioner 3 stretches into in the joint recess 10 with joint recess 10 joint contact produces ascending frictional force thereby make a pair of the both ends of upper and lower horizontal frame (21, 21 a) detachably fix a position simultaneously on cabinet body stand (1, 1 a). The friction positioning devices (3, 3a, 3b and 3 c) and the upper and lower transverse frames (21, 21 a) have similar structures and functions, and the friction positioning devices 3 and the upper transverse frame 21 are taken as an example for description.

As shown in fig. 7 and 8, a connection cavity 211 is further provided on the left and right end portions of the upper horizontal frame 21, respectively, the connection cavity 211 having a main cavity 211a extending laterally and a sub-cavity 211b arranged substantially perpendicular to the main cavity 211a. Wherein the sub-chamber 211b of the connection chamber 211 may extend from the front to the rear or from the top to the bottom so as to be arranged substantially perpendicular to the main chamber 211a and communicate with the main chamber 211a. The friction positioning device 3 comprises a T-shaped anchoring column 31, a tenon body 33 and a connecting sleeve 32, wherein the T-shaped anchoring column 31 comprises an anchoring column 312 and a convex connecting head 311 positioned at one end of the anchoring column 312. The anchor cylinder 312 is provided with a tapered hole having tapered surfaces (3121, 3122) disposed at left and right sides, and the tapered surfaces (3121, 3122) become inclined driving surfaces. The connecting sleeve 32 is arranged in the auxiliary cavity 211b, a jack (shielded by the anchoring cylinder 312 and not marked in the drawing) corresponding to the anchoring cylinder 312 is arranged on the connecting sleeve 32, the anchoring cylinder 312 is inserted into the main cavity 211a and extends into the jack, a convex connector 311 of the T-shaped anchoring cylinder 31 is clamped into the clamping groove 10 of the cabinet upright 1, the tenon 33 is screwed into the connecting sleeve 32 and arranged corresponding to the right conical surface 3122 of the conical hole, when the tenon 33 rotates and presses against the right conical surface 3122 of the anchoring cylinder 312, the tenon 33 can force the T-shaped anchoring cylinder 31 to retract inwards through the inclined driving surface 3122, so that the convex connector 311 is anchored on the notch transverse walls (104, 105) of the clamping groove 10. Rotating the tenon body 33 in the opposite direction can reduce the pressure of the tenon body 33 against the anchoring cylinder 312, so that the convex coupling 311 of the T-shaped anchoring post 31 releases the notch transverse walls (104, 105). Therefore, the tenon body 33 can be positioned on the upper horizontal frame 21 by means of the connecting sleeve 32, and can adjust the pressing strength pressed against the anchoring cylinder 312 by means of the thread screwing relationship with the connecting sleeve 32, so as to adjust the anchoring force of the convex connecting head 311. The arrangement of the connecting sleeve 32 is also beneficial to omitting the arrangement of an internal thread screwed with the tenon body 33 on the inner cavity wall of the auxiliary cavity 211b, so that the influence of the arrangement of the thread on the structural strength of the transverse frame and the structural limitation are reduced. The magnitude of the anchoring force of the friction positioning device 3 can be conveniently adjusted by rotating the tenon body 33. Of course, as another embodiment, it is also possible to provide the anchoring cylinder 312 with a tapered groove, the tapered surface of which becomes the inclined driving surface. The tenon body 33 can be a straight rod or the like. In this embodiment, the tenon body 33 is a pin 33 having a tapered tail. Therefore, the dowel can be easily purchased in the market as the tenon body 33, and special independent research and development and manufacturing are not needed, so that the manufacturing cost is saved.

As another embodiment, the tenon body 33 can be further arranged corresponding to the left side tapered surface 3121 of the tapered hole. In this way, the tenon body 33 can force the T-shaped anchor stud 31 to protrude outwards via the inclined driving surface 3121 so as to anchor the convex coupling head 311 against the groove bottom wall 101 of the snap-in groove 10. Of course, other embodiments of the inclined driving surface can be adopted to achieve the above effects, and are not listed here.

As shown in fig. 8, a convex ring 313 is further disposed on the anchoring cylinder 312, the convex ring 313 is disposed behind the convex connector 311, and the pressing spring 34 elastically presses between the convex ring 313 and the connecting sleeve 32 and is sleeved on the anchoring cylinder 312 in a penetrating manner. In this way, at the initial stage of installation, the pressing spring 34 can maintain the inclined driving surface 3122 and the tenon 33 in a pressed state, and the T-shaped anchor stud 31 can be preliminarily positioned.

According to the above scheme, it can be found that the friction positioning device 3 is firstly a clamping device which can clamp the left end and the right end of the upper transverse frame (21) and the lower transverse frame (21 a) into the clamping groove (10). The connector 311 of the friction positioning device 3 can pass through the upper opening of the clamping groove 10 from top to bottom and is inserted into the clamping groove 10 and slides to a proper position. In the front-rear direction, the connecting head 311 is limited by a pair of front-rear divided groove side walls (102, 103) of the clamping groove 10, so that the window frame 2 is positioned in the front-rear direction. Secondly, the friction positioning device 3 is also a bearing device which can generate enough upward friction force by being in clamping contact with the clamping groove 10 to offset the weight of the upper transverse frame (21), the lower transverse frame (21 a) and the glass plate (22), so that the glass window frame 2 can be positioned in the vertical direction. Thus, the friction positioning devices 3 respectively arranged at the four corner positions of the glass window frame 2 cooperate to firmly and detachably position the glass window frame 2 on the cabinet upright post (1, 1 a). In addition, when the glass plate 22 is damaged, the connector 311 of the friction positioning device 3 on the upper horizontal frame 21 can be loosened to allow the upper horizontal frame 21 to move upwards away from the glass plate 22, or the connector 311 of the friction positioning device 3 on the lower horizontal frame 21a is loosened to allow the lower horizontal frame 21a to move downwards away from the glass plate 22, so that a sufficient space is formed between the pair of upper and lower horizontal frames (21, 21 a) to separate the glass plate 22, and then the glass plate 22 can be conveniently replaced without detaching the whole glass window frame 2 from the cabinet body 100.

As shown in fig. 6 and 8, to reduce the back-and-forth shaking of the window frame 2. And the left end part and the right end part of the upper transverse frame 21 are respectively provided with a positioning fixture block 5. One end of the positioning fixture block 5 is clamped into the upper connecting groove 213 of the upper horizontal frame 21 and locked on the upper horizontal frame 21 by the fastener 50. The other end of the positioning fixture block 5 extends into the clamping groove 10 of the cabinet body upright post 1. Similarly, positioning locking blocks 5 are provided on the left and right end portions of the lower horizontal frame 1a, respectively. Therefore, the front and back shaking of the glass window frame 2 is greatly reduced by means of the combination of the positioning fixture blocks 5 and the clamping grooves 10.

As shown in fig. 8, in the transverse direction, the left end surface of the upper horizontal frame 21 protrudes beyond the left end surface of the glass plate 22, so that a horizontal gap L is formed between the left end surface of the glass plate 22 and the cabinet upright 1 on the left side. Similarly, a horizontal gap is formed between the right end surface of the glass plate 22 and the right cabinet upright 1a (the structure is similar to that shown in fig. 8, so that the relevant view is omitted and the understanding can be made with reference to fig. 8). Thus, the left end and the right end of the glass plate 22 do not need to be matched with the pair of cabinet upright posts (1, 1 a) for installation, and the precision requirement on the transverse width dimension of the glass plate 22 can be reduced. When the glass plate 22 is assembled, the glass plate 22 can be directly installed in a space defined by the pair of upper and lower transverse frames (21, 21 a) after the pair of upper and lower transverse frames (21, 21 a) are pre-installed on the pair of cabinet body upright posts (1, 1 a) and are initially positioned, and does not need to be inserted between the pair of cabinet body upright posts (1, 1 a) from top to bottom. Also, the glass plate 22 does not need to be moved from bottom to top to be detached from the pair of cabinet uprights (1, 1 a) during detachment. In addition, the horizontal gap can also be an air supplement gap, so that the cabinet body 100 has proper air intake.

Due to the above features and advantages, the present invention may be applied to cabinets such as storage cabinets, as well as the fume hood 100.
